Renovated hotel gives hope to homeless man
For
the first time in a long time, David Broderick has a positive outlook
on his life of 40 years. Having served time in jail, diagnosed as
HIV-positive 18 years ago and homeless for the past two-and-a-half
years, Broderick received good news in early December.
January 9, 2009
For the first time in a long time, David Broderick has a positive outlook on his life of 40 years.
Having served time in jail, diagnosed as HIV-positive 18 years ago and
homeless for the past two-and-a-half years, Broderick received good
news in early December.
He would be one of 44 people to move into the renovated Pennsylvania
Hotel at Carrall and East Hastings, not far from the alley where he
slept and regularly got robbed.
"It's made my life substantially more positive," said Broderick,
sitting in a chair Wednesday in his college dorm-sized room at the
hotel. "It's less stressful, less worrisome. It improves my life
incredibly, and I'm very, very thankful for that."
The Pennsylvania was originally built in 1906 and vacant for seven
years since 2001. The hotel and its staff celebrated its official
re-opening Wednesday with a street party, pancake breakfast and
speeches from Mayor Gregor Robertson and B.C. Housing Minister Rich
Coleman.
The renovated rooms are equipped with kitchens and bathrooms, including
showers. Unlike many hotels in the Downtown Eastside, the Pennsylvania
offers round-the-clock support services.
During the Courier's visit Wednesday, Broderick stopped by the hotel's
front desk to get a staff person to give him his anti-viral medication.
That type of service, he says, wasn't available when he and his ex-wife
lived in a Downtown Eastside hotel more than two years ago. The Wonder
Rooms was infested with rats and mice and rife with maintenance
problems.
"We had live wires hanging from our ceiling, the door was broken, the
windows were broken, the fridge leaked, there was no sink in our room
and we were paying $800 a month," he said, noting he and his wife were
evicted for complaining about the hotel's condition.
Broderick, who is a lot thinner than the 230 pounds he used to weigh,
is fighting a drug addiction. He doesn't like to talk about it but said
"it's incredible the amount of drugs that I'm not doing now because I
have a place where I can just go and close the door and be away from
everybody."
His room costs $375 a month, and he pays for the rent from his monthly
social assistance cheque. He was referred to the hotel from staff at
Onsite, the housing and counselling centre above Insite, the city's
supervised injection site.
Mark Townsend, co-executive director of the PHS Community Services
Society, which operates the Pennsylvania, said choosing who qualifies
to move into the hotel is difficult.
People living in substandard hotels, using homeless shelters and who
can't afford to pay rent are candidates, as are people with mental
health and/or addiction problems.
"Primarily, it's for people living in the Downtown Eastside that don't
have their own bathroom and some other basic things," Townsend said.
"Then past that, they might have a mental health problem, an addiction
or need a nurse or doctor."
The PHS bought the hotel and pub for $2.1 million in September 2001
from the Greater Vancouver Housing Corporation and Human Resources
Skills Development Canada.
Since then, the PHS worked with all three levels of government and
Concord Pacific, which contributed $3.6 million in a heritage density
swap, to renovate the hotel.
Total capital cost was $14.3 million.
"Now that I'm here, I plan to get my life back together," said
Broderick, before digging into a pancake breakfast. "However that is, I
don't know right now, but like I say I'm thankful and happy."

A judge confronts his fear of AIDS
A judge confronts his fear of AIDS Jon-Jo Douglas once made witness don mask
January 11, 2009
Hamilton - An Ontario judge so misinformed about how AIDS is spread
that he ordered an HIV-positive witness to be masked in his courtroom
has since spent a day at Casey House hospice, where he shook hands with
patients.
The unusual educational visit – and a later face-to-face discussion
with his chief justice – have ended the disciplinary proceedings
against Justice Jon-Jo Douglas.
"He knew that we were not his greatest friends when he first came here,
so I thought that it took courage for him to come," said Dr. Ann
Stewart, medical director at the Toronto hospice for people with
HIV/AIDS, who had publicly criticized Douglas after his conduct came to
light last year.
"He asked a lot of questions. He's clearly learned a great deal since a
year ago," said Stewart, noting Douglas – once so seemingly phobic he
ordered documents handled by the witness to be bagged – offered a very
"firm" handshake to one patient in particular.
"The folks who met him and spoke with him felt very positive about it,"
she said, noting Douglas explained during his visit that before
entering the legal profession, he'd worked as a hospital orderly and
"knew a little about infection control."
It was that experience, he said, that prompted him to ask for rubber
gloves for his court staff during the November 2007 trial of a man
accused of sexually assaulting a fellow inmate at a provincial jail.
The victim was HIV-positive.
Douglas, a judge of the Ontario Court of Justice in Barrie, went to
Casey House last summer following a complaint to the Ontario Judicial
Council by the province's Criminal Lawyers Association, the Canadian
HIV/AIDS Legal Network and the HIV & AIDS Legal Clinic in downtown
Toronto.
News of his visit wasn't made public. It was mentioned in a
confidential letter judicial council registrar Marilyn King sent
Tuesday to a complainant. The Star obtained a copy. The groups alleged
Douglas's conduct was an example of "shockingly discriminatory
thinking" and suggested Douglas lacked the temperament required of a
judge.
At one point, Douglas, a former Toronto prosecutor, had the case moved
to a bigger courtroom to create more distance between himself and the
witness.
Although the Crown attorney insisted extreme measures were unnecessary,
Douglas claimed – wrongly – that HIV will live in a dried state for
years.
That serves to illustrate that despite decades of public education,
there's still an "HIV panic out there in the world," said Richard
Elliott, the HIV/AIDS legal network's executive director.
While the Judicial Council can order public inquiries into complaints
against judges and remove them from the bench, that penalty would be
out of line for the behaviour at issue in this case, said Paul
Cavalluzzo, a Toronto lawyer experienced in judicial disciplinary
hearings. Exercising an option available under Ontario's Courts of
Justice Act, the council decided against a public inquiry, sending the
case to Chief Justice Anne-Marie Bonkalo for what was described in the
letter as a "discussion" with Douglas. Douglas "now fully understands
the concerns with his conduct" and "has learned from the experience,"
King's letter said.
"The Chief Justice advised that Justice Douglas has expressed his
apologies for his conduct, with sincere regret for any harm his
behaviour may have caused to the witness in the proceeding or to others
with HIV/AIDS, and for any impacts that his behaviour may have had upon
the public."
While Bonkalo told the council ignorance about HIV/AIDS isn't a
systemic problem among her court's judges, she's asked her educational
committee to consider a session on HIV/AIDS in future programs on
"pandemic management in the courtroom."
Elliott and Stewart called it a step in the right direction.

African-Canadian community grapples with AIDS 'stigma'
AIDS
remains a disproportionate threat to Nova Scotia’s African-Canadian
community and the recent “criminalization” of the disease has made
matters worse, experts say.
January 12, 2009

Ryan Taplin/Metro Halifax
David Divine, the James R. Johnston chair in black Canadian studies at
Dalhousie University, says HIV-positive black people face a dual
discrimination, which can make AIDS testing a hard sell. |
Halifax - AIDS remains a disproportionate threat to Nova Scotia’s
African-Canadian community and the recent “criminalization” of the
disease has made matters worse, experts say.
Larry Baxter is chairman of the Nova Scotia Advisory Commission on
AIDS. He has said the province’s strategy on HIV-AIDS, announced in
2003, lacked input from black communities.
“I don’t think much has changed,” he said yesterday. “There are
still issues of stigma, lack of information and lack of discussion
within the community.”
Two cases in Ontario where HIV-positive men were charged after
having sex with women and not disclosing their status may discourage
some men from getting tested, Baxter said.
“There’s the thinking that if you don’t know, you can’t be held criminally liable,” he said.
David Divine, the James R. Johnston Chair in Black Canadian Studies
at Dalhousie University, said the bigger problem is funding and
attitude.
“In terms of a general movement of interest and information
gathering, that most definitely has increased (since 2003),” he said.
“You can have significant sums of money available to an agency, but
if the right people are not in that agency with the right attitudes …
you’re not going to get anywhere.”
Divine said it’s difficult for a black person to go for an AIDS
test. “They are continuously afraid of being discriminated against not
only because of their colour, but because the very possibility of
having HIV-AIDS carries such a profound stigma.”
The Health Association of African Canadians is making dealing with
AIDS one of its focuses for African Heritage Month in February.
President Phyllis Marsh-Jarvis said fear, religious beliefs and stigma
play a key role in discouraging people in her community from discussing
AIDS.

Criminal HIV cases do more harm than good, group warns
HIV
advocacy groups -- and now two respected AIDS doctors -- say such
prosecutions are doing more harm than good, and are calling for
authorities to stop criminalizing what they consider a public-health
issue.
January 13, 2009
|
Handout/Canwest News ServiceFile photo of Johnson Aziga, who is the first
person in Canada to be prosecuted for murder in an HIV infection case for allegedly
having unprotected sex without disclosing his health status. |
When a Toronto man was charged last week with sexual assault for
knowingly exposing his girlfriend to HIV, it seemed like the logical
action for police to take, and followed the pattern of an increasing
number of such cases.
It was the second charge of its sort in two weeks in Ontario, and comes
in the midst of a landmark murder trial of an HIV carrier who allegedly
infected several women, two of whom later died of AIDS.
But HIV advocacy groups -- and now two respected AIDS doctors -- say
such prosecutions are doing more harm than good, and are calling for
authorities to stop criminalizing what they consider a public-health
issue.
Dr. Mark Wainberg, a Montreal doctor who headed the International AIDS
Society for two years, publicly joined the anti-criminalization
movement with an editorial in the journal Retrovirology last month, and
admits his stance might seem "counter-intuitive."
But, like others, he argued that publicity about the scores of criminal
HIV cases that have cropped up across Canada is adding to the negative
aura around the disease, discouraging people from coming forward to get
tested, and thus furthering the virus's spread.
The criminal law should be used when someone deliberately tries to
infect another person -- through a needle prick or similar malicious
action -- but not in the context of consensual sex, he said.
"We don't want to stigmatize and, in a way, you are stigmatizing
HIV-positive status," said Dr. Wainberg, who received the Order of
Canada for his HIV-AIDS research. "We're not doing enough to encourage
testing, and decriminalizing transmission would be a step in the right
direction."
Dr. Wainberg conceded that there is little empirical evidence yet that
criminal cases are, in fact, keeping potentially infected people
underground.
But a study about to get underway in Ontario will examine how the
criminal cases are affecting people who already know they are
HIV-positive, said Barry Adam, a University of Windsor sociologist and
research director of the Ontario HIV Treatment Network, who is leading
the survey.
Not everyone in the field, though, views the criminal cases with
distaste. Dr. Robert Remis, head of Ontario Epidemiologic Monitoring
Unit, said other avenues, such as counselling and public health laws
should be used first on
people who exhibit irresponsible sexual behaviour. But using the
criminal law is "just the right thing to do" in some circumstances, he
said.
"To knowingly and sort of willfully expose someone else to a what can
be a fatal disease I think is unacceptable," said Dr. Remis.
"It's beyond the limit, just like it's illegal to bash someone on the
head with a stick. It just happens to be a viral stick. But it's a
potentially serious assault."
Though definitive statistics are hard to find, more than 80 people --
mostly men -- have been charged in Canada with criminal offences for
exposing sexual partners to HIV, according to a study about to be
published in the Canadian Journal of Law and Society by Dr. Adam and
colleagues.
The Supreme Court provided the legal underpinning in a 1998 decision
that said someone who does not disclose he or she has HIV does not have
their partner's consent for sex, making the act an assault. Darren Eke,
a spokesman for Rob Nicholson, the justice minister, suggested the
Harper government has no plans to change that law.
Meanwhile, prosecutions have picked up steam of late, with at least 10
in each of the last three years, said Alison Symington of the Canadian
HIV-AIDS Legal Network, which is opposed to most of the cases.
In the latest case, a 29-year-old Toronto man was charged with
aggravated sexual assault after having consensual, unprotected sex with
a female friend and failing to tell her he was HIV-positive. Police
said they believe there were other unsuspecting partners, as well.
A similar charge was laid last month against a 53-year-old man from St. Catharines, Ont.
Earlier in December, the Ontario Court of Appeal imposed a one-year
jail sentence on a man convicted of aggravated sexual assault after he
had unprotected sex twice with his girlfriend, and failed to tell her
during their 18 months together about his HIV status. The trial judge
had given him a lighter, conditional sentence.
The man had "deceived [her] throughout their entire relationship
concerning a medical condition that could expose her to a
life-threatening illness," the appeal judges said in bumping up the
punishment.
Grabbing most attention, though, is the case of Johnson Aziga, on trial
now in Hamilton, Ont., on two counts of first-degree murder after
allegedly having a spate of unprotected sexual encounters with partners
who never learned of his HIV infection. Two eventually died of
AIDS-related cancers.
The jury saw video testimony given by one of the women, looking gaunt and emaciated, just weeks before she died.
Vancouver's Dr. Julio Montaner, another world-renowned HIV/AIDS
researcher, said criminal prosecution of transmission during consensual
sex is a complicated issue but he, too, said he sees little benefit
from it except in the most extreme cases.
And he noted that police never charge people for passing on other infectious diseases.
"HIV is a problem but so is human papilomavirus (HPV), which leads to
cervical cancer and anal cancer," he said, referring to another
sexually transmitted infection. "Are we going to legally prosecute
anyone who transmits a communicable disease? Is that the kind of
society we live in?"

Activists label Canadian Blood Services donation policy discriminatory
“As
soon as I was able to, and as soon as the blood drive came to my city,
I was there,” Olsen recalled in a phone conversation with the Straight.
“In the interview [with the nurse] there’s extra questions they ask you
specifically, face to face. And one question is, ‘Have you had sex,
even once, with another man any time between now and 1977?’ ” Olsen
answered honestly, in the affirmative. He was brusquely informed that
his blood would not be taken.
January 15, 2009
Eight
years ago, at age 17, Michael Olsen was unceremoniously blacklisted.
Now 25, B.C.’s representative to the national executive of the Canadian
Federation of Students, then living in Nanaimo, was attempting to give
blood for the first time.
“As soon as I was able to, and as
soon as the blood drive came to my city, I was there,” Olsen recalled
in a phone conversation with the Straight. “In the interview [with the
nurse] there’s extra questions they ask you specifically, face to face.
And one question is, ‘Have you had sex, even once, with another man any
time between now and 1977?’ ” Olsen answered honestly, in the
affirmative. He was brusquely informed that his blood would not be
taken.
“I was told I was put on a confidential blacklist,”
Olsen said. “What was worse, for me, was the nurse who interviewed me
specifically was fairly unkind. She told me I lead a very unhealthy
lifestyle.…It was embarrassing.…I was newly open about it [my
sexuality] at that point and I was so young, and it was very
frustrating for me, because I have always been very safe with my sexual
life.”
Olsen had run up against a long-standing policy of
Canadian Blood Services to permanently exclude men who have sex with
men from donating blood (the type of sex, whether oral or anal, is not
specified). When potential donors visit a CBS blood clinic, they are
presented with a questionnaire in two parts; Part 1 is filled out
alone, and Part 2 is done with a staff member, which is where sexual
activity is raised.
A “yes” answer from a man to the question,
“At any time, have you had sex with a man, even one time since 1977?”
brings a lifetime ban; a similar answer to the question, “In the past
six months, have you had sex with someone whose sexual background you
don’t know?” brings only a six-month deferral. (Being born in certain
African countries, having had malaria, cancer, or other health
ailments, and the use of illegal injection drugs brings a lifetime ban,
as does taking money or drugs for sex at any time since 1977; paying
money or drugs for sex results in a temporary deferral.)
CBS
spokesperson Ron Vezina insisted its policy is not meant to be
discriminatory. “We base our decisions on science, on epidemiology,” he
said in a phone conversation from Ottawa. “The epidemiology tells us
that as a population risk, men who have sex with men have the highest
prevalence of HIV, and that’s why they get deferred, just like other
groups, like people that are born in African countries where the
prevalence and incidence [of HIV] is very high.” He added that
individuals who have been deferred from giving blood and do not test
positive for an infectious disease can always donate at the Canadian
Blood Services’ NetCAD research facility at UBC, which studies
transfusion medicine. (Appointments can be booked by telephone at
604-221-5515 or email at researchdonations@blood.ca)
But
with the federal blood bank often facing critical shortages—most
recently last fall, when, on October 29, CBS announced that the
national blood inventory had dropped by more than 40 percent in the
previous two months, with only two days’ supply on hand for common
blood types—is it time for the organization to rethink its policy?
Many,
including Jennifer Breakspear, executive director of Vancouver LGBT
community centre the Centre, think so. “The Canadian Blood Services not
accepting blood from gay men has been an issue for the queer community
for a number of years,” she told the Straight by phone. “It’s not
specific to risky behaviours; rather, it’s ruling out an entire segment
of the population.…Canadian Blood Services is in a dire need for the
blood supply, and yet there may be a considerable number of gay men
that would be happy to donate and are just being stopped right off the
bat by their orientation.”
Rob Hughes, a Vancouver lawyer with
Smith & Hughes Barristers & Solicitors, believes the CBS’s
policy should be reviewed. “It is kind of discriminatory towards gay
men when you have a policy in place that is focused on the gender of
your sexual partner rather than specific risk behaviours that would
apply equally to heterosexual or homosexual couples engaged in sex,” he
noted in conversation with the Straight. “Someone who’s heterosexual
but engaging with multiple sex partners in unprotected sex, I would
think, would be at a higher risk of infection—and would be somebody
that you’d want to exclude from the blood supply—than a gay man who’s
in a monogamous long-term relationship engaging in protected sex.”
Although,
according to Hughes, there might be a basis for a human-rights
complaint regarding CBS’s policy—“Discrimination on the basis of sexual
orientation would be something that is protected in both the Canadian
Human Rights Act and the B.C. Human Rights Code,” he says—to date no
such complaint has been filed.
In Quebec, however, one legal
challenge against Héma-Québec, which handles the province’s blood
supply, is winding its way through the courts: a small-claims suit of
$1,500 filed in 2005 by Adrian Lomaga, then a second-year law student
at McGill University.
According to Lomaga, now a practising
lawyer in Toronto with Rachlin & Wolfson LLP, the suit has now been
transferred to the Superior Court after Héma-Québec added Health Canada
as a third party to the action. “It’s been placed in the trial list,
and we’re waiting for a trial date, which may be another year or so,”
he told the Straight by phone. Although any decision regarding Lomaga’s
case would technically apply only to Héma-Québec, “in reality, because
Health Canada sets down the policy for Canadian Blood Services and
Héma-Québec, any type of decision, if it’s in my favour, will have an
effect across Canada,” Lomaga said. Another case with potentially
wide-ranging repercussions is a $100,000 suit filed in 2002 by CBS
against Kyle Freeman. Freeman, in protest of the CBS’s deferral policy,
sent anonymous e-mails to the blood bank claiming he was an
HIV-negative gay man in a committed long-term relationship who had
donated blood after lying about his sexual history. That case is
expected to go to trial in the Ontario Superior Court of Justice this
year.
One of the loudest voices in the call to overhaul the
CBS’s policy is the Canadian Federation of Students (CFS), which in
2006 took up the issue as an official campaign. Since that time, it has
taken part in stakeholder consultations with the blood bank, but to
date no policy changes have been made. In June 2007, the CBS announced
it had conducted a review of its deferral policy for men who have had
sex with men; it decided to uphold its policy but continue
investigating the issue.
“We committed a research agenda to
look at this issue further,” CBS’s Vezina said. “We also made funding
available through the Canadian Institutes for Health Research for
someone to tackle that issue. No one to date has jumped on the
bandwagon to use the funds to conduct research at the university level,
so the file is open.”
What arose out of stakeholder
discussions during its latest review, Vezina said, was that simply
reducing deferral times for men who have sex with men is not
acceptable. “Our stakeholders said, ‘Essentially, you’re asking a gay
man, for the privilege of donating blood, you want me to be celibate
for a year, or five years, or 10 years. That’s not the way you should
be assessing risk.’ ”
Brent Farrington, national deputy
chairperson of the CFS, explained from Ottawa by phone that “we felt
that [a shorter deferral period] was an inappropriate gesture on their
[the CBS’s] part, in the sense that our issue is with the nature of
their question. They are essentially saying that the MSM [men who have
sex with men] population is a dirty population, so by saying that, ‘Oh,
well, if you only engaged in MSM activity five years ago and haven’t
done it since, then you’re fine to give blood again,’ that just
reinforces what we consider to be the draconian practice that they’re
using.”
What the CFS and groups like Egale Canada (which did
not return calls to the Straight) want is a behavioural approach to
screening blood donors rather than a demographics-based questionnaire.
That would involve asking donors details about their sex lives, such as
whether they practise safe sex, and screening them accordingly.
But
recent memory is still scarred by the tainted-blood scandal of the
1980s, in which more than 1,000 patients contracted HIV and 20,000
contracted hepatitis C from blood transfusions given by the Red Cross
between 1986 and 1990—and after which, in 1998, Canadian Blood Services
took over the national blood supply (with Héma-Québec operating in the
province of Quebec). Any question of messing with a system that has
operated safely for the past 10 years raises understandable fears about
contaminating the blood supply.
Only Italy, to date, has
adopted a behavioural-screening approach, Vezina noted, adding: “We’re
all anxious for them to publish some data. I don’t think Canadians want
to be a guinea pig. It’s up to us not to be on the leading edge of this
policy.” Even so, Vezina said that CBS is continuing to investigate the
issue, and it is scheduled to report its preliminary research to its
board of directors in February.
“We are not sitting
passively,” he insisted. “In the course of the past year, we’ve polled
over 40,000 of our donors on what would it mean to them in terms of a
new approach to screening and also gauging what that would do to our
donor base. For instance, if we start asking about sexual practices, is
it going to turn some people off from donating blood to have to go
through those questions every time? Is it going to sideline too many
from being able to donate?…If you make a change on one side of the
safety coin, you’ve got to make sure that it’s a calculated measure.
You can’t be implementing a new deferral that is going to wipe out 50
percent of your donors. You’re going to be in constant shortage.”
In
the meantime, the CFS says it is keeping a close eye on the issue,
hoping for progress. “I’m very happy that they [CBS] are evaluating
their policies when it comes to the MSM deferral criteria,” Farrington
said. “I mean, it’s frustrating, but I do appreciate that it’s beyond
their control that the time lines are so slow.” Olsen said: “We’ve had
discussions on whether or not we’d make a human-rights complaint on
this, and the consideration still stands…but we’re not taking action on
it specifically yet.”
In the meantime, Olsen can only shake
his head whenever he hears urgent appeals for blood. “Every year, when
they talk about this [blood shortages], or every time I hear it on the
radio, it does frustrate me a lot,” he admitted. “I laugh, really. I
find it very frustrating.”
As to how effective CBS’s screening
policy is, given that it’s an honour system, it seems that Kyle Freeman
is not the only man who has ever withheld information in order to
donate blood. “I have a lot of friends who actually have lied for that
question [about men having sex with men], and they donate blood
anyway,” Olsen confessed. “A lot of people know they have clean blood,
because they do get checked on a regular basis, and they know the blood
is going to be screened again anyway. They just answer no to the
question.”

Three Letter Plague: A Young Man's Journey through a Great Epidemic by Jonny Steinberg
In
this book, Steinberg poses two questions: why do stigma and shame
prevent people - predominantly men - from taking the first step towards
self-preservation by testing for HIV? And why do people who have the
opportunity of accessing life-saving drugs not take up the opportunity
to get treatment their government now offers?
The journalist and ethnographer Jonny Steinberg is well known in South
Africa and the US for tackling issues confronting the African country's
emergent democracy. Now he turns his attention to AIDS.
Three Letter Plague, Steinberg says, was prompted by reading Edwin
Cameron's exploration of stigma and den-ial in Witness to Aids, his
personal account of his journey to testing and public disclosure.
Steinberg poses two questions: why do stigma and shame prevent people -
predominantly men - from taking the first step towards
self-preservation by testing for HIV? And why do people who have the
opportunity of accessing life-saving drugs not take up the opportunity
to get treatment their government now offers?
In search of answers Steinberg journeys to a remote hilltop community
in the Eastern Cape, and embarks on a quest through the trenchant
themes of shame, anger, secrecy, fal-lacy and fear. The scene of his
investigation is “Ithanga” (not its real name), a village of 700 mostly
unemployed people and without electricity or running water.
Here Steinberg befriends the charismatic, dreadlocked, 29-year-old
autodidact entrepreneur he calls Sizwe Magadla, the proprietor of
Ithanga's only successful shop. “Sizwe was healthy and strong and had
never tested for HIV, which puts him in a category shared by most South
African men his age.” About to be married to his pregnant girlfriend,
Sizwe is aware of the testing, counselling and antiretroviral treatment
programme available 20 miles away in Lusikisiki, run by the legendary
Dr Hermann Reuter. Yet he is reluctant to take the test.
Ambivalent about his own experiences of being tested for HIV as a young
gay man at university, Steinberg recognises Sizwe's dilemma. Together
the two men explore the implications of HIV and Aids for the community
and discover the “architecture of shame”' - the elemental anxieties of
contamination and moral panic attendant on a disease that meddles with
deep metaphors and primal patriarchal cultural taboos surrounding
generative fluids - blood and semen - and sex.
This book has been greeted with widespread critical acclaim for its
rich description; gripping accounts of superstition, witchcraft, views
on “Western” science, ancestral spirits, evocative tales and sharp
studies of a range of key indicative characters - including doctors,
nurses, volunteers, treatment activists, traditional healers and
troubled ancestors. This is justified praise. Steinberg commands the
narrative deftly, with inquisitiveness, energy, and wry
self-deprecation. He thinks with the bracing scepticism of the cultural
sociologist and writes with the detached coolness recommended in
Greene's dictum that objectivity requires an icicle in the heart.
Steinberg states clearly that he is a “lay person” and critical
outsider, and that, having “lost nobody” to the epidemic, he does not
write as a witness to AIDS.
The value of this book lies beyond the pleasures of its lambent prose
and stylistic aplomb. What compels is the sustained, intimate, yet
fractured dialogue between Sizwe and Jonny - black man and white man
from utterly divergent backgrounds - who share nonetheless a
recognition of the stigma of disgrace imposed upon HIV-positive people.
Steinberg asks why more than two thirds of the approximately 262,000
people on antiretroviral (ARV) treatment in South Africa are women.
“Where are the missing men? Why are they so less likely to find their
way to ARV treatment than women?” The answers reside, as this book
startlingly reveals, in conventional notions of masculinity of which
Sizwe and Jonny are victims. Testing, public disclosure, and fighting
stigma require a profound re-evaluation of the inhibitions of
masculinity. And this challenge to the primordial conventions of
patriarchy, as the treatment statistics show, seems to be much more
frightening to men than death itself.

AP/Washington Post Examines PEPFAR's Impact on HIV/AIDS in Africa
According
to the AP/Post, supporters and critics alike "agree that prevention is
the weakest link" among global HIV/AIDS programs and will need more
emphasis in the future.
January 12, 2009
The AP/Washington Post on Sunday examined the impact of the President's Emergency Plan for AIDS Relief on the burden of HIV/AIDS in African countries. According to the AP/Post, "countless Africans ... will always be grateful to [President] Bush for his war on AIDS."
PEPFAR initiatives have increased the number of Africans receiving
antiretroviral treatment fortyfold over the past five years by working
through grass-roots organizations as well as "higher-profile charities
and big state clinics," the AP/Post reports. Still of the 1.5 million Africans
who died from AIDS-related causes in 2007, less than one-third had
access to antiretroviral treatment. The number of new HIV cases also
continues to exceed the number of people receiving treatment. In addition, the current economic downturn has caused concern about whether the five-year, $48 billion in PEPFAR funding passed last year will be delivered.
Although numerous programs cite successes achieved as a result of
PEPFAR funding, several advocates disagree about how the initiative has
impacted HIV/AIDS in Africa. According to the AP/Post,
some advocates have suggested that the initiative overemphasizes
abstinence and faith-based programs. Helen Epstein, an HIV/AIDS expert
and consultant for the United Nations and the World Bank,
said PEPFAR's focus on abstinence has hindered prevention efforts by
failing to address certain African cultural practices involving
simultaneous long-term relationships. According to Epstein, PEPFAR
could achieve a greater impact if funding were directed at
strengthening health care systems rather than addressing a single
disease. Johanna Hanefeld, researcher at the London School of Hygiene and Tropical Medicine, added that the Global Fund To Fight AIDS, Tuberculosis and Malaria more effectively utilized HIV/AIDS programs for improving health care
and training because it did not distribute funding among many different
groups.
However, many experts and advocates disagree with
PEPFAR's critics and believe that the initiative will have a lasting
impact on the HIV/AIDS in Africa. Mark Dybul, U.S. Global AIDS
Coordinator who administers PEPFAR, said, "In Africa, you can't tackle
development goals unless you tackle HIV/AIDS." According to Dybul, the
initiative also is a major supplier of condoms to several African
countries, demonstrating that PEPFAR does not emphasize abstinence
exclusively. "It's the largest international health initiative in
history for a single disease," Dybul said. Francois Venter, who heads a
PEPFAR-funded program at the University of the Witwatersrand in South Africa says, "PEPFAR is different" because of its emphasis on
measurable targets. Josh Ruxin, assistant professor of public health at Columbia University,
said President Bush and his administration "deserve a lot more credit
than they received" for launching PEPFAR. "[I]t is impossible to deny
the results and achievements of PEPFAR," Ruxin said, adding that he
hopes President-elect Barack Obama will continue the initiative while
shifting its focus away from abstinence and providing funding for
programs involving commercial sex workers and abortion.
According to the AP/Post,
supporters and critics alike "agree that prevention is the weakest
link" among global HIV/AIDS programs and will need more emphasis in the
future (Nullis, AP/Washington Post, 1/11)

Leading human rights organisation calls for release of HIV workers in Senegal
Ironically,
the arrests happened just days after Senegal hosted the 15th
International Conference on AIDS and STIs in Africa (ICASA). The
conference had heard that laws criminalising sex between men were
hampering HIV prevention work with gay and other men who have sex with
men in a number of African countries.
January 12, 2009
The conviction of
nine men involved in HIV prevention work for “indecent and unnatural
acts” and “forming associations of criminals" in Senegal on 6th January
demonstrates how laws against homosexuality hamper the prevention of
HIV, a leading human rights organisation has said. New York-based Human Rights Watch has called for the immediate release of the men pointing out that the
convictions and the treatment of the men contravene civil rights
declarations that Senegal has agreed to uphold.
The men were arrested
at the home of an HIV outreach worker near the Senegalese capital Dakar
in late December 2008. The police confiscated condoms and lubricant and
arrested nine men who were present in the house. All were subsequently
charged under article 319.3 of the country’s penal code for “improper
and unnatural acts”. Condoms and lubricants seized during the police
raid were used by prosecutors as evidence of homosexual activity. All
the men were convicted and received the maximum five-year prison
sentence. Furthermore, the men were also found guilty of “criminal
association”, which can involve a sentence of between three and five
years.
“Outreach workers and people seeking HIV prevention or treatment
should not have to worry about police persecution. Senegal should drop
these charges and repeal its sodomy law”, said Scott Long of Human
Rights Watch. Ironically, the arrests happened just days after Senegal
hosted the 15th International Conference on AIDS and STIs in Africa
(ICASA). The conference had heard that laws criminalising sex between
men were hampering HIV prevention work with gay and other men who have
sex with men in a number of African countries. “Senegal’s sodomy law
invades privacy, criminalizes health work, justifies brutality, and
feeds fear”, said Long, who highlighted that Senegal has acted contrary
to a number of human rights agreements by arresting the men.
“These
nine men were arrested merely on suspicion of engaging in homosexual
conduct. In that case, international human rights provisions mandate
their immediate release”, said Human Rights Watch. According to Human
Rights Watch, the arrests also violate article nine of the
International Covenant on Civil and Political Rights. This is supposed
to guarantee the right to liberty, the security of person and rights
against arbitrary detention. Senegal ratified this agreement in 1978.
Concern has also been expressed by Human Rights Watch about the safety
of the men, who were apparently beaten whilst in police custody. Human
Rights Watch is calling for the nine men to be separated from other
prisoners for as long as they remain in custody and to receive
appropriate health care, including HIV treatment if this is needed.
Senegal is far from being the only African country to deny civil rights
to lesbians and gays. Last
year, gay rights activists were arrested at the HIV Implementers’
meeting in Uganda after protesting about a Ugandan government
announcement that gay and other men who have sex with men would have no
HIV resources directed towards them. The HIV prevalence rate amongst gay men in Uganda is 26% and one
of the themes of last year’s International AIDS Conference in Mexico
City was the disproportionate impact of HIV on gay and other men who
have sex with men in resource-limited settings. The conference
heard that even in countries with generalised HIV epidemics, the
prevalence was higher amongst gay and other men who have sex with men
than in the general population.
The Senegalese arrests “will have a
chilling effect on AIDS programs”, said Long of Human Rights Watch, who
highlighted that there was “panic” in a number of Senegalese HIV
organisations, particularly those working with gay and other men who
have sex with men and other vulnerable groups. Said Human Rights Watch,
“laws criminalizing consensual sexual conduct drive these vulnerable
populations underground and permit gross violations of the fundamental
rights to life, freedom of expression and association, and health.”

Antiretroviral Therapy To Be Made Available to HIV-Positive People in
Afghanistan for First Time, Health Ministry Announces
Forty
of the 504 people diagnosed with HIV/AIDS in the country were selected
to receive the drugs based on their medical status and need, among
other criteria. It is suspected that there are an additional 2,000 to
2,500 undocumented HIV/AIDS cases nationwide.
January 9, 2009
For the first time, people living with HIV/AIDS in Afghanistan soon
will receive antiretroviral therapy from the government, the Ministry of Health announced recently, IRIN/PlusNews reports. Forty of the 504 people diagnosed with HIV/AIDS in the country
were selected to receive the drugs based on their medical status and
need, among other criteria. It is suspected that there are an
additional 2,000 to 2,500 undocumented HIV/AIDS cases nationwide.
Saif ur-Rehman, head of the national HIV/AIDS program at the health
ministry, said that $50,000 has been allocated to supply the
antiretrovirals and that the ministry "will allocate more in the
future." The government is launching the treatment program with help
from various donors, and Rehman said that the ministry expects the World Health Organization to have imported the drugs by the end of January. The drugs will be
distributed at no cost in Kabul and Herat provinces initially, but more
people could receive access in the future, IRIN/PlusNews reports. Consultations will be made with WHO and international
not-for-profit groups to determine how the antiretrovirals are
dispensed, and health care workers will be trained to oversee treatment
regimens. According to health officials, Afghanistan has
been slow to introduce no-cost antiretroviral therapy, and availability
and access remain low. In addition, the stigma surrounding the disease
makes it difficult to determine if people are accessing the drugs
through the private sector. Although the number of documented
HIV/AIDS cases in Afghanistan is among the lowest worldwide, there are
many factors that could contribute to the spread of the disease,
including a lack of awareness, conflict, the poor social status of
women and rising injection drug use.
Some health care workers in the country are calling for immediate action to curb the spread of HIV, IRIN/PlusNews reports.
Rehman added, "We want to tackle the existing gap between real and
suspected HIV cases by 2010 so as to draw up appropriate plans and
implement relevant projects." Health ministry officials and health
workers have cited limited technical capacity to make use of funding
and donor efforts. The national HIV/AIDS control program was launched
in 2003 and has received pledges of more than $30 million up to 2013.
The health ministry hopes the planned opening of a UNAIDS office in the country in 2009 will help fill the gap in national capacity (IRIN/PlusNews, 1/7).

USA Today Examines HIV/AIDS, Legal System in China
In
the mid-1990s, thousands of people in China's Henan province contracted
HIV through unsanitary blood drives the local government approved.
Since then, many people who contracted HIV from the transfusions have
sought compensation from the government; however, most have encountered
difficulty bringing their cases to court.
January 15, 2009
USA Today on Wednesday examined legal issues surrounding HIV/AIDS in China, a
country that "tightly" controls its legal system and "routinely"
dismisses lawsuits that are considered "politically sensitive." In the
mid-1990s, thousands of people in China's Henan province contracted HIV
through unsanitary blood drives the local government approved. Since then, many people who contracted
HIV from the transfusions have sought compensation from the government;
however, most have encountered difficulty bringing their cases to
court. According to USA Today, the Sanmenxia Intermediate People's
Court in Henan would not say why it declined to accept cases related to
the blood transfusions.
Wan Yanhai, a Chinese HIV/AIDS advocate,
estimates that more than 100,000 people contracted HIV from the blood
transfusions. According to Wan, "Even until now, the government has
refused to inform people who received blood transfusions" that they
might have been exposed to HIV. Lan Zhixue, lawyer and co-founder of
the Institute of Democratic Society in China, said that because the
hospitals involved in the transfusions "have no legal responsibility,"
the "victims receive no compensation." According to Li Fangping,
another Chinese lawyer, the government's dismissal of such court cases
is fueling a "growing distrust of the people's court system." Wan said,
"It is time for the government to compensate the blood victims, and it
is also time to promote fundamental political change" in China.
According to USA Today, several grassroots initiatives recently were
launched to call on the government to "loosen its grip and give people
more freedom and legal rights." The "most daring" is a document called
Charter 08, which is "snowballing" on the Internet and now has more
than 7,000 signatures, USA Today reports (MacLeod, USA Today, 1/14).

HIV non-progressor status established soon after infection
“One
of the main interests of this study lies in its ability to identify
early prognostic factors of becoming a long-term non-progressor”,
comment the investigators, “our results show that patients with
baseline HIV [viral load] and HIV DNA below detection limits have a 60%
chance of being long-term non-progressors.
January 12, 2009
HIV-positive patients who maintain a CD4 cell count above 500 cells/mm3 for at least eight years after their HIV diagnosis have very low levels
of HIV DNA soon after their infection with HIV and subsequently have
very slow increases in this marker, French investigators report in the
January 1st edition of the Journal of Acquired Immune Deficiency Syndromes. The investigators therefore believe that “early prognostic factors” are associated with long-term non-progression of HIV.
Long-term non-progressors are defined as HIV-positive individuals who
do not need to take HIV treatment and who remain symptom-free with a
CD4 cell count above 500 cells/mm3 for at least eight years after their infection with HIV.
Most of the research involving this small group of patients (who only
represent between 1% and 5% of HIV-positive individuals), has focused
on their outcomes once their non-progressor status has been identified.
Little is therefore known about the earlier years of HIV infection in
these patients.
Investigators from France described the course of HIV infection in a
group of 664 patients in the ANRS SEROCO/HEMOCO cohorts who had a CD4
cell count above 500 cells/mm3 at the time of their HIV diagnosis, which was between 1988 and 2006.
The investigators found that 60 of these patients were still symptom-free and had a CD4 cell count above 500 cells/mm3 without antiretroviral therapy eight years after their diagnosis. These patients were therefore long-term non-progessors.
Researchers looked at the factors associated with long-term
non-progressor status; the natural history of HIV infection in
non-progressors; and the factors associated with the loss of
non-progressor status either because of a fall in CD4 cell count to
below 500 cells/mm3 or the appearance of symptoms of HIV infection.
Non-progressors were younger than patients whose HIV disease progressed
at the time of HIV diagnosis (25 vs 28, p = 0.02). They also had higher
median CD4 cell counts at diagnosis (840 vs 668 cells/mm3, p < 0.0001) and higher median CD4 cell percentages (p = 0.0002).
Baseline viral load was lower in non-progressors than progressors, and
a higher proportion of non-progressors had an undetectable viral load
at the time of HIV diagnosis (24% vs 3%).
Further, non-progressors also had lower amounts of HIV DNA in
peripheral blood mononuclear cells than progressors and were more
likely to have a baseline HIV DNA below the limit of detection (13% vs
1%).
Next, the investigators looked at the natural history of HIV infection in the patients with long-term non-progressor status.
They found that median CD4 cell count fell by between 32 and 16 cells/mm3 per year depending on age (bigger falls were seen in younger patients).
Among all the 59 long-term non-progressors with viral load information
available, mean viral load at the time of HIV diagnosis was a little
over 1500 copies/ml. It increased by a mean of 0.040 log10 copies per year, and the mean eight year total increase in viral load was 0.32 log10, meaning that mean viral load at this point was approximately 3000 copies/ml.
Viral load was undetectable at baseline in 16 non-progressors. It
remained undetectable for a median of six years in these patients and
seven individuals maintained an undetectable viral load for ten years.
There was information on baseline HIV DNA for 47 patients. At baseline the mean was 2.19 log copies/106 in men and 1.75 log copies/106 in women. It increased by mean of 0.069 log copies/106 per year, the total mean eight year increase being 0.55 log copies/106.
In 19 patients, the first HIV DNA measurement was undetectable. Of
these individuals, ten also had an undetectable baseline viral load.
HIV DNA remained undetectable for a median of 3.6 years in these 19
patients.
Median duration of follow-up for the 60 long-term non-progressors was
16 years. During this period, 36 patients lost their non-progressor
status. This occurred a median of eleven years after diagnosis with HIV
(or three years after achieving non-progressor status). All but three
of these 36 patients lost their non-progressor status because their CD4
cell count fell below 500 cells/mm3.
The only baseline factor associated with loss of non-progressor status
was HIV DNA level. Patients with HIV DNA above the limit of detection
at the time of their HIV diagnosis were almost three times more likely
to experience HIV disease progression than patients with an
undetectable HIV DNA at baseline (adjusted hazard ratio, 2.8, 95% CI
,1.2-6.8).
Furthermore, the investigators found that patients who lost their
non-progressor status had higher annual increases in HIV DNA (above
0.103 log copies/106, adjusted hazard ratio, 2.2, 95% CI, 1.0-4.8).
“One of the main interests of this study lies in its ability to
identify early prognostic factors of becoming a long-term
non-progressor”, comment the investigators, “our results show that
patients with baseline HIV [viral load] and HIV DNA below detection
limits have a 60% chance of being long-term non-progressors”.
They conclude, “our study shows that long-term non-progressor status
may be established early during infection. Low level of HIV in
peripheral blood mononuclear cells at enrolment was found to be a
strong predictor of the duration of long-term non-progression.”

Premature Aging of CD4 Cells Linked to Faster Disease Progression
Scientists
have known for many years that the immune systems of elderly people are
not as robust as those of younger people. One of the primary reasons
for this is that as a person’s CD4 cells reproduce over many years,
they slowly become less functional with each generation. Experts in
genetic research call this immunosenescence. Immunosenescence can occur
much more rapidly in people with HIV, given the constant destruction
and production of immune cells in response to the virus. What has
remained unknown, however, is whether this premature aging of CD4 cells
impacts HIV disease progression.
January 12, 2009
While they may not develop wrinkles or liver spots, CD4 cells can show signs of premature aging. This can lead to faster disease
progression in HIV-positive people, conclude the authors of a study published in the January 7 issue of the Journal of Acquired Immune Deficiency Syndromes.
Scientists have known for many years that the immune systems of elderly
people are not as robust as those of younger people. One of the primary
reasons for this is that as a person’s CD4 cells reproduce over many
years, they slowly become less functional with each generation. Experts
in genetic research call this immunosenescence.
Immunosenescence can occur much more rapidly in people with HIV, given
the constant destruction and production of immune cells in response to
the virus. What has remained unknown, however, is whether this
premature aging of CD4 cells impacts HIV disease progression.
To explore the possibility, Weiwei Cao, MD, PhD, from the Department of
Medicine at Danbury Hospital in Connecticut and his colleagues examined
the CD4 cell functioning of 20 HIV-positive people with rapid disease
progression and 40 people with slow progression. The study volunteers
were all drawn from the Multicenter AIDS Cohort Study (MACS), and a
rapid progressor was defined as progression to an AIDS diagnosis within
four years of infection.
Cao’s team found that one of the fundamental signs of an “aging”
cell—the loss of cell receptors called CD28—was far more likely to be
present in rapid-progressors than slow progressors. Other signs of
premature CD4 cell aging, such as the ratio of two types of CD4 cells,
called memory and naïve cells, were less clear.
While the authors state that the cellular aging process can continue
even in people on antiretroviral (ARV) therapy, they recommend that
more research be conducted to determine whether—and to what degree—ARV
therapy helps slow this process. They also call for studies exploring
the removal of aging cells to make room for new cells, and for a
therapy that may rejuvenate aging cells.

Immune system defects persist in people who start treatment late
People
who started treatment with a CD4 count below 350 in a major
international clinical trial were left with the immune system profile
of people in advanced old age even though they appeared to have good
responses to treatment.
January 13, 2009
People who started treatment with a CD4
count below 350 in a major international clinical trial were left with
the immune system profile of people in advanced old age even though
they appeared to have good responses to treatment, according to a
report in the February 1 st edition of Clinical Infectious Diseases.
The findings suggest that additional immunotherapies may eventually be
needed to achieve a full restoration of immune health in people taking
antiretroviral therapy.
As people age, their immune systems
begin to decline, losing the ability to respond to new pathogens, and
the CD4:CD8 cell ratio falls, indicating that regardless of the
absolute CD4 cell count, the immune system's ability is weakened.
Researchers examined the immunological profiles of a large population
of treatment-naïve HIV-positive people who took part in the ACTG 384
study, a three-year randomised comparison of first-line treatment with
either a protease inhibitor or a non-nucleoside reverse transcriptase
inhibitor (NNRTI) in combination with either d4T and ddI or AZT and
3TC. Another group was assigned to take both the protease inhibitor and
the NNRTI. Patients switched to another of the study regimens after
virological failure.
Initial results from ACTG 384 were reported in 2002,
and showed that efavirenz was superior to nelfinavir in first-line
treatment. Subsequent analysis showed that greater CD4 cell increases
on treatment were strongly associated with a higher baseline CD4 count.
The new analysis published in Clinical Infectious Diseases looks specifically at T-cell subsets to determine the quality of the immune response to treatment.
Comprehensive immunological data were available for 623 of the 978
participants in the study, and there were no significant differences in
baseline characteristics between those who underwent full assessments
and those who did not.
Participants were assessed in five baseline CD4 cell strata: < 50, 51-200, 201-350, 351-500 and >500 CD4 cells/mm 3.
CD4 cell counts increased by approximately same number of cells in each
CD4 cell strata: around 250 cells gained after 96 weeks regardless of
baseline CD4 cell count, and around 300 cells after three years. As a
consequence the median CD4 cell count in those with a baseline count
below 50 still lay below 350 cells after three years, while in those
with a CD4 cell count between 50 and 200, the median count reached 400
cells/mm 3 after three years.
People with low CD4 counts when starting treatment thus continued to be
exposed to a higher risk of serious illness despite a successful
response to treatment throughout the follow-up period. In comparison,
those who started treatment with a CD4 count above 350 cells/mm 3 had a median CD4 count of 739 after three years.
The researchers then looked at the proportion of CD4 cells that were
newly generated (so-called naïve cells). The body’s ability to generate
naïve T-cells declines with age due to the atrophy of the thymus, the
organ in which lymphocytes are assigned their roles as different types
of T-cells (such as CD4 cells).
It is this age-related loss of naïve cells that leaves the elderly
vulnerable to new pathogens and unable to replace memory cells that are
lost. The health of the balance between naïve cells and memory cells is
expressed as a ratio, with a ratio of 0.87 recorded in an age-matched
HIV-negative control group of 48 individuals in this study.
The researchers found that, regardless of age, people who started
antiretroviral therapy with a higher CD4 count (above 350 cells/mm 3)
had a significantly greater improvement in the ratio of naïve cells to
memory CD4 cells after three years, indicating a superior quality of
immune reconstitution (p=0.008). These patients exhibited a normal
naïve cell to memory cell ratio after three years of treatment.
The study also found that despite three years of viral suppression
below 50 copies/ml, individuals with CD4 counts below 500 cells/mm 3 still exhibited a higher level of activated CD4 cells than the
HIV-negative control group, and all participants continued to exhibit
higher levels of CD8 cell activation after three years than the
HIV-negative control group.
The persistence of immune activation might be explained either by continued low-level viral replication, or by microbial translocation across a gut wall damaged by HIV.
The consequences of persistent immune activation, note the authors,
might be cardiovascular disease or cancers, although the mechanisms by
which persistent HIV-related immune activation might cause health
problems for people with HIV still need to be explored.
The
authors conclude: “Relying solely on absolute CD4+ cell counts as a
measure of immune reconstitution may be misleading. Understanding
differences in immune cell subsets and ratios … may refocus the goal of
ART towards normalization of T cell subsets and higher CD4+ thresholds
for initiating ART.
“These findings support ART initiation at a threshold of 350 cells/mm 3 and further suggest use of an even higher CD4+ cell count, at which
time CD4+ naïve cell populations and naïve-memory cell ratios are more
likely to still be intact.”
An accompanying editorial by
Steven Deeks and Elvin Geng of San Francisco General Hospital notes the
significance of these findings for individuals in resource-poor
settings, where the median CD4 count at the time of treatment
initiation recorded in several large studies was between 108 and 131
cells/mm 3.
“Persistent inflammation and immunological defects are likely the norm
globally. If anything, the greater prevalence of chronic viral,
helminthic and protozoal infections in these regions is likely to
exacerbate the persistent T cell subset derangements seen in [ACTG
384], with potentially negative consequences.”
They point out that regardless of how early people are encouraged to
start treatment, many people will not start treatment until much later
in the course of HIV infection, and may be left with permanent
immunological defects, leaving them vulnerable to a greater range of
health problems than HIV-negative people or those who started treatment
earlier. “Novel immune-based therapeutics aimed at reversing these
defects are urgently needed,” they argue.
However, they admit that the causal link between immunological defects,
persistent immune activation and poorer health outcomes still needs to
be proved, noting “determining the causal association among these
factors will be a challenge, given the complexity of the human immune
system”.

Gilead Developing New Four-in-One HIV Drug
The
new pill will contain four Gilead drugs—tenofovir (Viread),
emtricitabine (Emtriva), the experimental integrase inhibitor
elvitegravir and a drug that boosts elvitegravir blood levels,
currently called GS9350.
January 13, 2009
A four-in-one antiretroviral pill is being developed by Gilead Sciences and, according to a report by Bloomberg News, is expected to enter a clinical trial by this summer.
The new pill will contain four Gilead drugs—tenofovir (Viread), emtricitabine (Emtriva), the experimental integrase inhibitor elvitegravir and a drug that boosts elvitegravir blood levels, currently called GS9350.
Gilead is negotiating with the U.S. Food and Drug Administration (FDA)
on the size and scope of the trial. Not only will the study explore the
effectiveness of this novel drug combination, but it will also help
answer lingering questions about the safety of elvitegravir and GS9350.
Elvitegravir is currently being evaluated in Phase III studies in
people who are treatment experienced; GS9350 is in a much earlier stage
of development.
If the study results are positive, the new pill could become an
alternative to the only existing treatment that includes a full ARV
regimen in one tablet, Atripla (tenofovir, emtricitabine and efavirenz).

Mutant host cell protein sequesters critical HIV-1 element
Scientists have identified a new way to inhibit a molecule that is critical for HIV pathogenesis.
January 15, 2009
Scientists
have identified a new way to inhibit a molecule that is critical for
HIV pathogenesis. The research, published by Cell Press in the January
16th issue of the journal Molecular Cell, presents a target for
development of antiretroviral therapeutics that are likely to
complement existing therapies and provide additional protection from
HIV and AIDS.
Infection of human cells with HIV-1 requires
multiple events that involve complex interactions between viral
elements and cellular proteins. The virus must copy key parts of its
DNA as mRNA molecules through a process called transcription. The mRNA
molecules must be properly "spliced", or rearranged, and then
transported out of the cell nucleus and into the cytoplasm where the
mRNAs can be "translated" into viral proteins.
"Although there
has been a great deal of effort directed at understanding HIV-1
transcription, mRNA splicing and nuclear export, little is known about
the translational control of HIV-1 RNA in the cytoplasm," says senior
study author, Dr. Johnny J. He from the Center for AIDS Research at
Indiana University School of Medicine.
Dr. He and colleagues
examined a protein called HIV-1 Nef that is translated from completely
spliced HIV-1 RNA. Nef is very important for HIV pathogenesis and AIDS
disease. "It is highly conceivable that intervention with Nef
expression may complement the current anti-HIV therapies that are
mainly targeted at HIV-1 protease and reverse transcriptase, providing
a better treatment outcome," explains Dr. He.
The researchers
found that a mutant form of Src-associated protein in mitosis of 68kDa
(Sam68), a host cellular protein involved in HIV-1 pathogenesis,
specifically interacts with nef mRNA and directly suppresses Nef
expression. This particular Sam68 mutant was previously shown to
inhibit HIV-1 replication by overriding its wild-type counterpart's
function in nuclear export of unspliced and incompletely spliced HIV
RNA. However, the mutant Sam68 was present in the cytoplasm, suggesting
that it may serve some function in the cytoplasmic stage of the HIV-1
life cycle.
The ability of the Sam68 cytoplasmic mutant to
interfere with Nef correlated with its ability to induce stress
granules in the cytoplasm. Stress granules regulate gene expression at
the translational level in response to a variety of external stimuli.
Importantly, nef mRNA was targeted to and enriched in the stress
granules.
"Taken together, these results demonstrate that
stress granule induction and nef mRNA sequestration account for this
translational suppression of Nef expression and offers a new strategy
for development of anti-HIV therapeutics to buttress our fight against
HIV/AIDS," concludes Dr. He.
