'Compassion' club busted as pot ring
North
Vancouver RCMP charge 13 after ring allegedly supplied recreational
users, not those with medical marijuana needs. It's an unusual case,
she said. "We have busted other dial-a-dope rings, but this is the
first time I have seen one that has been passing themselves off as a
compassion association," she added.The B.C. Compassion Club Society
said the group had caused some concern.
March 18, 2009
Vancouver
- The RCMP say they have busted a pot-delivery operation that was
masquerading as a compassion club that provided marijuana for medical
needs.
Mounties in North Vancouver yesterday announced 13 people
had been charged with trafficking in a controlled substance, following
an investigation that began in September, 2007, after police received
an anonymous tip through Crime Stoppers. The arrests put an end to the
operation of the so-called Internet Compassion Association, police
said.
"People would call them up and make their order. [The
organization] would make the delivery," RCMP Corporal Marlene Morton
said.
Cpl. Morton said the customers were not people with
medical marijuana needs, but rather recreational drug users looking for
a convenient source of product.
It's an unusual case, she
said. "We have busted other dial-a-dope rings, but this is the first
time I have seen one that has been passing themselves off as a
compassion association," she added.
Police say they seized six
kilograms of marijuana from a storage locker of the alleged ringleader
of the operation, 39-year-old Jason Thon, who is charged with a count
of trafficking in a controlled substance. Some arrests in the case were
made in the middle of last month, with some suspects appearing in court
late last week, but police announced details of the investigation only
yesterday.
A total of 41 charges have been forwarded against
various individuals, with more charges expected, police said. Arrest
warrants are out for four individuals accused of being parties to the
ring.
The B.C. Compassion Club Society said the group had caused some concern.
"It
was definitely creating some confusion, and we were receiving calls
from people looking for them and not aware we have much more stringent
requirements for becoming a member," said Jay Leung, a spokesman for
the non-profit organization that has been providing medicinal cannabis
since 1997.
Mr. Leung said club officials did not contact
police, but rather considered the whole situation a bit of a nuisance.
"We set whoever called us straight," he said.
He said the club
never had any direct contact with the alleged ring, and did not think
it affected his group's credibility. But he said the ring might stir up
lingering controversy around medical marijuana in society, despite its
benefits.
"There's still this controversy, so the compassion
clubs worked long and hard over the past decade to establish good
practices and standards and establish our credibility," he said. "So
it's problematic when people don't have those motivations, aren't
following those guidelines but are just using the name in the hopes of
protecting what they are doing."

Pressure Mounts Over Medicines Regime
"For
12 years the response from the brand-name pharmaceutical industry has
been: block it, stop it, slow it down, make it difficult, [and] harass
the governments and generic drug makers," said Jeff Connell, director
of public affairs with the Canadian Generic Pharmaceutical Association.
March 18, 2009
A
generic drug company plans to halt the production and shipment of cheap
life-saving HIV/AIDS pills to Africa unless changes are made to
Canada's Access to Medicines Regime.
This has prompted
concerns from Rwanda, which is the only country to receive medication
under the regime, and comes amidst demands the government not turn its
back on Africa as a whole.
Canadian generic pharmaceutical
company Apotex became the first company to take advantage of the Access
to Medicines regime when it shipped seven million pills to Rwanda last
year. It will send a second batch in September, said Apotex public
affairs director Elie Betito, after which time it will cease production
unless the government amends the Regime.
"We are not ready to
participate if the rules are the same," Mr. Betito said, though he did
not sound optimistic the company's concerns would be addressed. "This
government is not interested in reviewing [the legislation again]."
Parliament unanimously passed the regime—known at the time as the Jean Chrétien Pledge to Africa—in 2004.
The
generic medicines regime is one of only a few in existence in the world
and is based on an agreement hammered out by the WTO in 2003. The
agreement loosened patent rules so generic drug companies like Apotex
could work with the compulsory licensing of patented medicines and
proceed with legally producing and exporting lower-cost versions of
brand-name medicines to developing countries.
But by the time
the government got around to conducting a mandatory review of the
legislation in 2007, not a single pill had been produced and exported.
While Apotex and others said the government needed to change the law to
make it easier for developing countries and the company to take
advantage of the legislation, the government ended up recommending no
changes to the regime.
Despite the apparent setback, Apotex
developed Apo-TriAvir, a combination of three medications in one pill,
which is designed to prolong the life of most AIDS patients for years
and costs two-thirds less than brand-name medications. Rwanda became
the first country to receive the pills when a shipment arrived in
September.
Though Rwandan officials said they had not been
informed of Apotex's intention to end production, they were hopeful the
company would not follow through on its threat.
"The bottom
line is that experts from [Rwanda] selected Apotex because it provided
a combination with fewer tablets and was cheaper," said Déo Nkusi,
first counsellor at the Rwandan Embassy in Ottawa.
According
to Dr. Jules Mugabo, from Rwanda's Treatment and Research Aids Center,
which negotiated the Apotex deal, the African nation will have no
choice but to wait and see.
"Being able to get the medication
that our people need so much from Apotex was an opportunity we could
not just leave," he said in an interview from Kigali, Rwanda's capital.
"We will go through the same process, from tendering to when
the medication will reach us because we don't have control or any
influence over those mechanisms."
The process for securing
drugs continues to be the subject of criticism from the likes of the
Canadian HIV/AIDS Legal Network, which says the whole thing can take
more than four years and does not match the situation's urgency.
"It's
an unnecessarily complicated process for the suppliers and the
purchasers—and the people who end up paying the price are the patients,
because this logjam doesn't end up getting broken," said Richard
Elliott, executive director of the Canadian HIV/AIDS Legal Network.
The
current system requires a generic company to have separate negotiations
with patent-holders and arrange a separate licence for each purchasing
country, as well as each new order of medicines that follows.
What's
needed instead, argued Mr. Elliott, is a "one-licence solution" that
authorizes manufacturers to produce the same drug for export to any
number of approved countries, rather than go through a renewal process
every time.
This would allow faster, cheaper and ultimately more competitive pricing and markets for life-saving medicine, he said.
Critics also blame intense lobbying by brand-name pharmaceutical companies at the WTO and in Ottawa.
"For
12 years the response from the brand-name pharmaceutical industry has
been: block it, stop it, slow it down, make it difficult, [and] harass
the governments and generic drug makers," said Jeff Connell, director
of public affairs with the Canadian Generic Pharmaceutical Association.
He said "big pharma intentions" were made clear when 58
multi-national drug companies "lined up" to sue South Africa, which had
sought to change its Patents Act in 1998 as a vehicle to import cheap
generic drugs from Brazil and India.
No other countries have
sought to apply the Canadian legislation yet, but sources tell Embassy
that Ghana did make preliminary contacts. Though Apotex said no
governments have started the process for new orders, the Ghanaian
Embassy in Ottawa did not rule out the possibility of direct contacts
from its government back home.
Details are also emerging
suggesting opposition MPs could table a private members' bill in both
Houses proposing 13 specific reforms to CAMR. They have been courted by
an alliance of numerous groups, and the bill should be in this March,
according to people familiar with the process.
The United
Nations estimates there are more than 30 million people infected with
HIV/AIDS, more than 80 per cent of whom live in developing countries.
In Rwanda some 290,000 people are living with HIV/AIDS with about
63,000 requiring antiretroviral treatment.

HIV/AIDS Rate in D.C. Hits 3%
Considered a 'Severe' Epidemic, Every Mode of Transmission Is Increasing, City Study Finds
March 15, 2009
At least 3 percent of District residents have HIV or AIDS, a total that
far surpasses the 1 percent threshold that constitutes a "generalized
and severe" epidemic, according to a report scheduled to be released by
health officials tomorrow.
That translates into 2,984
residents per every 100,000 over the age of 12 -- or 15,120 --
according to the 2008 epidemiology report by the District's HIV/AIDS
office.
"Our rates are higher than West Africa," said Shannon
L. Hader, director of the District's HIV/AIDS Administration, who once
led the Federal Centers for Disease Control and Prevention's work in
Zimbabwe. "They're on par with Uganda and some parts of Kenya."
"We
have every mode of transmission" -- men having sex with men,
heterosexual and injected drug use -- "going up, all on the rise, and
we have to deal with them," Hader said.
In addition to the
epidemiology report, the city is also releasing a study on heterosexual
behavior tomorrow. That report, funded by the CDC, was conducted by the
George Washington University School of Health and Health Services.
Among
its findings: Almost half of those who had connections to the parts of
the city with the highest AIDS prevalence and poverty rates said they
had overlapping sexual partners within the past 12 months, three in
five said they were aware of their own HIV status, and three in 10 said
they had used a condom the last time they had sex.
Together, the reports offer a sobering assessment in a city that for years has stumbled in combating HIV and AIDS and is just beginning to regain its footing. A more accurate accounting
of the crisis offers a chance to contain what is largely a preventable
disease.
So urgent is the concern that the HIV/AIDS
Administration took the relatively rare step of couching the city's
infections in a percentage, harkening to 1992, when San Francisco,
around the height of its epidemic, announced that 4 percent of its
population was HIV positive. But the report also cautions that "we know
that the true number of residents currently infected and living with
HIV is certainly higher."
The District's report found a 22
percent increase in HIV and AIDS cases from the 12,428 reported at the
end of 2006, touching every race and sex across population and
neighborhoods, with an epidemic level in all but one of the eight
wards. Black men, with an infection rate of nearly 7 percent, carry the weight of the disease,
according to the report, which also underscores that the District's HIV
and AIDS population is aging. Almost 1 in 10 residents between the ages
of 40 and 49 has the virus.
The report notes that "this
growing population will have significant implications on the District's
health care system" as residents face chronic medical problems
associated with aging and fighting a disease that compromises the
immune system.
Men having sex with men has remained the disease's leading mode of transmission.
Heterosexual transmission and injection drug use closely follow, the
report says. Three percent of black women carry the virus, partly a
result of the increase in heterosexual transmissions.
"This is
very, very depressing news, especially considering HIV's profound
impact on minority communities," said Anthony Fauci, director of the
National Institutes of Health's program on infectious diseases. "And
remember: The city's numbers are just based on people who've gotten
tested."
Ron Simmons, who is black, gay and HIV positive, said
he's not shocked by the study's findings. "You have a high incidence of
HIV among African Americans, and a lot of African Americans live in the
city," said Simmons, who is a member of a black gay support group.
"D.C. also has a high number of gay men, and HIV is high among gay
black men."
Charlene Cotton, a D.C. resident who got an HIV
positive diagnosis five years ago, said breaking the taboo on
discussing HIV is the key to moving forward. "You need to start at home
and talk about it," Cotton said. "It's so hush-hush."
Mayor
Adrian M. Fenty (D) said he is aware that some advocates have called on
elected officials and others to more aggressively and publicly address
the crisis. He praised the city's recent efforts, however, and
expressed his frustration about the struggle ahead.
"In order
to solve an issue as complex as HIV and AIDS, you have to step up," he
said. "It's the mayor and certainly other elected officials. But it's
also the community. You have this problem affecting us, and you tell
people how serious it is and it literally goes in one ear and out the
other."
David Catania (I-At Large), chairman of the D.C.
Council's health committee, said that although the District's testing
and monitoring have improved in the past two years, the AIDS office is
still playing catch-up. The city was in the forefront of the crisis
when it created the office in 1986, but it fell far behind. Hader took
control in 2007. She is its 12th director and the third in five years.
"Frankly,
there can be no excuse for the state of the HIV/AIDS Administration
that I found in 2005," Catania said. "I cannot speak to why it was not
a priority previously. For years prior to 2005, mayors and previous
individuals allowed things to exist in an unacceptable way. And I do
blame this government for part of the epidemic we're confronting."
Until recently, the District's AIDS office lacked a fully staffed surveillance unit to collect, analyze and distribute data. Inevitably, the office lost
credibility, and although it has received millions in federal and local
funds -- $95 million this year -- some care providers questioned
whether resources were being properly allocated.
Critics also
say congressional control over the District had restricted the AIDS
office's ability to combat the virus among drug injection users by
banning the use of local tax dollars for a needle exchange program. After almost a decade, the ban was lifted last year.
The study is the most precise count to date, according to the authors. The document is an update of a breakthrough 2007 report,
which brought into clearer focus a picture of a city in the grip of a
complex and "modern epidemic" that had traveled from a mostly gay
population to the general one and disproportionately hit blacks.
For
years, District HIV/AIDS workers depended on estimates that put the
rate at 1 of 20 living with HIV and 1 of 50 living with AIDS.
The
current study notes that its tracking occurred as the city made a
switch from a code-based counting system to a name-based one. The
surveillance unit interviewed medical providers to find unreported
cases, pressed providers who did not consistently report to the
administration and searched databases for unreported cases.
More
than 4 percent of blacks in the city are known to have HIV, along with
almost 2 percent of Latinos and 1.4 percent of whites. More than
three-quarters -- 76 percent -- of the HIV infected are black, 70
percent are men and 70 percent are age 40 and older.
Heterosexual
sex was the principal mode of transmission for blacks with the disease,
33 percent. Men having sex with men was the chief mode of transmission
for white residents, 78 percent; and Latinos, 49 percent. Black women
represent more than a quarter of HIV cases in the District, and most,
about 58 percent, were infected through heterosexual sex. About a
quarter of black women were infected through drug use.
The
companion study, "Heterosexual Relationships and HIV in Washington,
D.C.," is a detailed look at those whose social networks include
individuals at high risk of infection and aims to analyze people's
choices and actions before they set foot in a clinic or get HIV.
The
750-participant study targeted four areas in wards 1, 2, 5, 6, 7 and 8
with both high rates of AIDS and poverty. Salaries of a majority of
participants -- 60 percent -- were under $10,000 yearly; a similar
percentage had never been married; and 43 percent were unemployed.
The
survey's methodology -- interviewing those with connections to
high-risk networks rather than those who exhibit high-risk behavior
themselves -- highlights a shift in the direction by the CDC, which
developed the survey protocol.
There is good news in the AIDS
office's report: More people are getting HIV diagnoses early, while
they are still healthy, as a result of a policy of routine testing
implemented by the city in mid-2006. Publicly supported HIV testing
expanded by 70 percent.
Walter Smith, executive director of
the DC Appleseed Center for Law and Justice, praised the study but also
lamented that it did not offer more current data on new infections. The
report said that detailed information on new HIV cases is not included
because the transition from the code-based tracking system to a
name-based one takes five years to be mature, according to the CDC.
"I'm
not criticizing them for that," he said. "But we've had more testing,
more needle exchange programs. We don't have, at this moment, any
understanding about what impact the new programs have had."

Stop AIDS In Prison Act' (Waters, D, CA) Is 'Urgent Lifesaving Legislation,' Says AHF
AHF
commends Congresswoman Maxine Waters (D, CA) for reintroducing a bill
to provide comprehensive HIV testing, treatment and prevention for
inmates in federal prisons and upon re-entry into the community. The
bill, which is known as the Stop AIDS in Prison Act (H.R. 1429), had
been previously introduced by Waters (as H.R. 1943) where it was passed
by the House of Representatives during the 110th Congress by voice
vote; however, the Senate did not complete action on the bill prior to
adjournment.
March 16, 2009
AIDS Healthcare Foundation (AHF), the largest non-profit HIV/AIDS
healthcare provider in the US which currently provides treatment, care
and support services to more than 97,000 individuals in 21 countries
worldwide in the US, Africa, Latin America/Caribbean and Asia, today
commended Congresswoman Maxine Waters (D, CA) for reintroducing a bill
to provide comprehensive HIV testing, treatment and prevention for
inmates in federal prisons and upon re-entry into the community. The
bill, which is known as the Stop AIDS in Prison Act (H.R. 1429), had
been previously introduced by Waters (as H.R. 1943) where it was passed
by the House of Representatives during the 110th Congress by voice
vote; however, the Senate did not complete action on the bill prior to
adjournment.
"The 'Stop AIDS in Prison Act' seeks to address a major and growing
public health issue that disproportionately affects minorities and
women," said Michael Weinstein, President of AIDS Healthcare
Foundation. "By providing comprehensive HIV testing, treatment and
prevention services for inmates in federal prisons and upon their
re-entry back into the community, this legislation will go a long way
to help break the chain of new infections. We applaud Congresswoman
Waters for reintroducing and carrying this urgent lifesaving
legislation."
Waters announced the introduction of this bill at the Congressional
Summit on the Effects of HIV and Incarceration on Communities of Color,
an event on Capitol Hill organized by the National Minority AIDS
Council (NMAC). The legislation directs the Federal Bureau of Prisons
to test inmates upon entering and exiting federal prison and includes
an "opt-out" provision should inmates wish to decline being tested. The
bill also ensures that inmates found to be HIV-positive receive
treatment.
"In order to best address the nation's growing HIV/AIDS epidemic, the
CDC has recommended routine testing for HIV in all healthcare settings,
and health policy implemented in federal prisons should remain in line
with the government's own health guidelines," said Whitney
Engeran-Cordova, Director of the AHF's Public Health Division. "H.R.
1429 follows these sensible CDC guidelines. By making HIV testing
routine among the prison population, this bill will not only help
reduce the spread of infection among inmates, but it will also protect
the health of the community at large."

Natasha Richardson
Tony Award winner Natasha Richardson has passed away at the age of 45 after being removed from life support.
Family and friends, including mother Vanessa Redgrave and sister Joely
Richardson, were gathered around the actress in a New York hospital.
Richardson was hospitalized after a fall during a ski lesson on Monday
in Montreal.
Richardson was hospitalized in Montreal before
being airlifted to a New York hospital on Tuesday. Doctors said that
blood was leaking between her brain and skull, according to People .
"Liam Neeson, his sons, and the entire family are shocked and
devastated by the tragic death of their beloved Natasha," Neeson's rep,
Alan Nierob, said in a statement. "They are profoundly grateful for the
support, love, and prayers of everyone, and ask for privacy during this
very difficult time."
Time Out: New York reported Tuesday that her family had learned from doctors that she was
brain-dead, but several websites followed with reports that the
announcement was premature.
Richardson is married to actor
Liam Neeson and is the daughter of screen legend Vanessa Redgrave. The
45-year-old actress won a Tony Award for her role in the musical
Cabaret in 1998, and has also starred in several films, including Patty
Hearst and The Handmaid's Tale.

Haiti Making Progress Against HIV/AIDS, Challenges Remain, Opinion Piece Says
Haiti's
progress has been "particularly significant for a country where 60% of
the population lives below the poverty line of $2 per day," he writes,
adding, "Only four of every 10 Haitians have access to potable water,
and there is one doctor for every 10,000 inhabitants." However, the
"scenario is optimistic," Chelala writes, noting that the percentage of
HIV-positive test results among pregnant women has decreased by 50%
over the past 10 years.
March 16, 2009
There is "some good news" in the fight against HIV in the Americas,
Cesar Chelala -- an international public health consultant -- writes in
a Miami Herald opinion piece, adding that "most surprisingly, it's coming from Haiti,
one of the countries hardest hit by the epidemic." Chelala writes that
United Nations data show that about 2.2% of Haiti's population -- or
120,000 people -- are living with HIV/AIDS and that AIDS-related deaths
in the country have decreased in recent years. This compares with an
HIV/AIDS prevalence of 6.1% in 2001, according to Chelala. Haiti's
progress has been "particularly significant for a country where 60% of
the population lives below the poverty line of $2 per day," he writes,
adding, "Only four of every 10 Haitians have access to potable water,
and there is one doctor for every 10,000 inhabitants." However, the
"scenario is optimistic," Chelala writes, noting that the percentage of
HIV-positive test results among pregnant women has decreased by 50%
over the past 10 years.
The progress in fighting HIV/AIDS in
Haiti is "due in large part to the work of people like" Jean Pape -- a
Haitian doctor who focuses on HIV/AIDS and founded GHESKIO -- and Paul Farmer of Partners in Health, Chelala writes. PIH, along with its HIV Equity Initiative,
are "dedicated to preventing and treating AIDS in the context of
primary care; improving care for tuberculosis; optimizing treatment for
sexually transmitted infections; and emphasizing women's health,"
Chelala writes. More than 400 workers have been trained to administer
no-cost antiretroviral drugs within the community, and more than 1,500
HIV-positive people are receiving treatment, he writes.
According
to Chelala, "many challenges remain," and a majority of Haitians "still
lack sufficient sex education, for example." He adds that only 15% of
women and 28% of men between ages 15 and 24 know HIV prevention
methods, and both boys and girls are becoming sexually active at
earlier ages. In addition, Chelala notes that prevalence and incidence
rates have been declining more slowly in rural areas than in urban
areas.
Chelala concludes that the "advances in fighting the
epidemic in Haiti show that although much remains to be done to achieve
better results, a committed leadership, good planning, parallel
attention to prevention and care, and community involvement can
successfully control this terrible epidemic, even under the worst of
circumstances" (Chelala, Miami Herald, 3/12).
An abstract of Chelala's report -- "AIDS: A Modern Epidemic" -- is available online.

Thousands in Uganda, Kenya Misdiagnosed as Positive
A
new study suggests that thousands of HIV-negative Kenyans and Ugandans
were incorrectly diagnosed as positive due to faulty tests at voluntary
counseling and testing (VCT) centers...
March 16, 2009
A
new study suggests that thousands of HIV-negative Kenyans and Ugandans
were incorrectly diagnosed as positive due to faulty tests at voluntary
counseling and testing (VCT) centers, the Daily Nation reports.
The
study involved 6,255 people between ages 18 and 60 who sought VCT
services at testing sites in both countries. When two different tests
were performed on participants, 131 had “discrepant” results where one
was positive and the other negative. On the third test, 27 were
confirmed to be HIV positive.
Researchers found that rapid tests
such as Determine, Uni Gold and Capillus are normally used in poor
societies because they are cheap and that confirmatory tests are not
usually done at VCT sites in either country. However, assistant medical
services director Peter Cherutich maintained that these rapid tests are
the best method for countries such as Kenya and Uganda because they are
cheap and easy to use and do not require refrigeration.
The
risk of inaccurate diagnoses rises when rapid tests are done once
without a confirmation test. According to the report, this is because
they are “fraught with errors and as such, cannot alone be used to
determine whether an individual is positive or not.” Therefore
researchers suggest that positive results always be administered with a
follow-up test before a diagnosis is made.

Condom Distribution Not Answer to Curbing Spread of HIV in Africa, Pope Benedict Says
Distributing
condoms is not the answer to curbing the spread of HIV in Africa, Pope
Benedict XVI said on Tuesday while heading to Yaounde, Cameroon, as
part of a seven-day pilgrimage to the continent, the AP/Washington Post
reports. "You can't resolve it with the distribution of condoms,"
Benedict said, adding, "On the contrary, it increases the problem"
March 18, 2009
Distributing condoms is not the answer to curbing the spread of HIV in
Africa, Pope Benedict XVI said on Tuesday while heading to Yaounde,
Cameroon, as part of a seven-day pilgrimage to the continent, the AP/Washington Post reports. "You can't resolve it with the distribution of condoms,"
Benedict said, adding, "On the contrary, it increases the problem"
(Simpson, AP/Washington Post, 3/18). According to Benedict, addressing
HIV/AIDS will require a "two-fold" solution. He said, "The first is a
humanization of sexuality, spiritual renewal which brings with it a new
way of behaving ... secondly, a true friendship, especially for those
who are suffering, a willingness to make personal sacrifices" (Ward, Toronto Star,
3/18). Benedict, who also said the Roman Catholic Church is at the
forefront in fighting HIV/AIDS, will visit Angola and Cameroon
(Simpson, AP/Washington Post, 3/18).
Although the
Vatican's policy states that sexual abstinence should be used to curb
the spread of HIV, this stance has led some nuns and priests working
with HIV-positive people to "question the church's opposition to
condoms amid the pandemic ravaging Africa," the AP/Washington Post
reports (AP/Washington Post, 3/18). Jon O'Brien, president of Catholics for Choice,
said, "No responsible health care provider would suggest condoms are a
panacea." However, he added that condoms "are an absolutely vital
measure that people must have if they are to protect themselves and
their partners and stem the spread of the virus." According to O'Brien,
opinion polls indicate that millions of Catholics worldwide support
condom use. Therefore, the pope's statement was "a real tragedy because
it's not just an issue for Catholics," O'Brien said (Toronto Star,
3/18).
Many HIV/AIDS advocates also have spoken out about the
pope's stance. Rebecca Hodes -- director of policy, communications and
research for the Treatment Action Campaign -- said that if Benedict were serious about curbing the spread of
HIV/AIDS, he should focus on promoting access to condoms and
disseminating information about their use. Hodes said, "Instead, his
opposition to condoms conveys that religious dogma is more important to
him than the lives of Africans" (Simpson, AP/Washington Post, 3/18).
Stephen Lewis, head of AIDS-Free World,
said, "Every stitch of scientific evidence says condoms are the best
preventive measure we have against the virus." According to Lewis,
Benedict's statements were "another example of complete indifference to
the vulnerability of women, who are so hugely and disproportionately
affected by HIV/AIDS" (Toronto Star, 3/18).
According to London's Guardian,
in 2005 during a meeting with senior clergy from Africa, Benedict
called HIV/AIDS a "cruel epidemic" and said it could not be eradicated
with condoms. The pope said that the "traditional teaching of the
church has proven to be the only failsafe way to prevent the spread of
HIV/AIDS" (Butt, Guardian, 3/17).
According to CNN analyst and
senior correspondent for the National Catholic Reporter John Allen,
Benedict been clear that he intends to uphold the traditional Catholic
ban on artificial contraception. However, according to Allen, Benedict
also has asked a panel of scientists and theologians to consider
whether to allow condoms for married couples in which one partner is
HIV-positive, adding that it is not clear how the pope will decide the
issue ( CNN, 3/17).
Related Editorial
The pope "has every right to express his opposition to the use of
condoms on moral grounds, in accordance with the official stance of the
Roman Catholic Church," according to a New York Times editorial. However, the editorial continues that Benedict "deserves no
credence when he distorts scientific findings about the value of
condoms in slowing the spread" of HIV/AIDS. According to the Times,
Benedict's statement that condom distribution will not eradicate
HIV/AIDS is "clearly right" because condoms "alone won't stop the
spread of HIV." Instead, HIV/AIDS prevention programs should
incorporate initiatives to reduce the number of sexual partners,
promote safer-sex practices and advance other interventions to "bring
the disease to heel," according to the editorial. However, Benedict's
statement that condom use could worsen Africa's HIV/AIDS burden is
"grievously wrong," the editorial continues. It states, "There is no
evidence that condom use is aggravating the epidemic and considerable
evidence that condoms, though no panacea, can be helpful in many
circumstances."
The editorial states, "From an individual's
point of view, condoms work very well" in preventing HIV transmission.
In addition, from "a national perspective, condom promotion has been
effective in slowing epidemics in several countries among high-risk
groups, such as sex workers and their customers, but less effective in
slowing epidemics that have spread into the general population, as in
sub-Saharan Africa," the editorial says. It continues that this occurs
"probably because far too few people use condoms consistently and
correctly." According to the editorial, public health officials have
cautioned that condom use "cannot provide absolute protection" because
condoms sometimes "break, slip or are put on incorrectly." It continues
that the "best way" to avoid HIV transmission "is to abstain from
sexual intercourse or have a long-term mutually monogamous relationship
with an uninfected person." However, health officials regardless
"consider condoms a valuable component of any well-rounded program to
prevent the spread" of HIV/AIDS, the editorial says. It concludes, "It
seems irresponsible to blame condoms for making the epidemic worse"
(New York Times, 3/17).

New South African Research Center to Tackle HIV/TB
It's
estimated more than 33 million people are now living with HIV/AIDS.
More than 10 million of them are also believed to be infected with
tuberculosis. TB is the cause of death for many of them. The CDC, US
Centers for Disease Control, says since 1990, TB infection rates have
increased four-fold in countries with high rates of HIV.
March 19, 2009
Washington D.C - It's estimated one-third of the people living with
HIV, the AIDS virus, are also infected with tuberculosis. Health
officials say this dual epidemic is one of the most significant
challenges facing modern medicine. Now, South Africa is home to a new
research facility looking for new ways of treating the diseases.
The KwaZulu-Natal Research Institute for Tuberculosis and HIV is a
partnership between the Howard Hughes Medical Institute and the
University of KwaZulu-Natal in Durban. It's located in the epicenter of
South Africa's HIV/AIDS epidemic and the site of some of the first
cases of multi-drug and extremely drug resistant TB.
Dr. Bruce
Walker, a specialist in infectious diseases, says, "We're talking about
a really serious problem in terms of the convergence of these two
epidemics."
Dr. Walker is director of the Ragon Institute,
which is supported by Massachusetts General Hospital, the Massachusetts
Institute of Technology and Harvard University.
"One of the
most exciting parts of this whole project is the ability to conduct
research at the heart of these two epidemics. And have it really be
focused on the local problems that need to be solved," he says.

Dr. Thumbi Ndung'u, an associate professor at the University of KwaZulu-Natal, says HIV/AIDS makes TB infection much easier. "People don't normally die of
HIV/AIDS as such. People usually die of opportunistic infections that
come about as a result of the virus (HIV) weakening the immune system.
And among the common of the opportunistic infections that affect people
with HIV is tuberculosis," he says.
He says that the new
institute is a great opportunity for African researchers. "If you look
at the HIV/AIDS-TB problems as they exist today, they have an African
face. If you look at the people who are infected with HIV, with TB,
these people tend to be predominantly Africans. But you don't see
Africans at the forefront of inventive research on these problems. You
don't see the Africans at the forefront of trying to confront these
problems in a comprehensive and sustainable way. I think that there is
a tremendous opportunity here," he says.
One of the new institute's goals is to train a new generation of African scientists.
Dr.
Ndung'u says the extent of the HIV/AIDS epidemic in KwaZulu-Natal
Province is reflected among pregnant women who go to health clinics.
"In
some provinces like KwaZulu-Natal, where I'm working, the infection
rates actually approach 40 percent among women attending ante-natal
clinics. It's a very, very severe problem. And of course that's
compounded now by the problem of tuberculosis," he says.
Dr. Walker says the institute will take a different approach to tackling these diseases.
He
says, "Traditionally, in Africa, TB has been treated by one group of
doctors and HIV by a completely separate group of doctors. What we need
is integration both at the clinical level and at the research level, so
that we have under the same roof people that are trying to deal with
this co-epidemic."
But he says although the research focuses
on HIV and TB, the findings may help in other areas as well. "These
sorts of studies have wide ranging implications for the way the immune
system deals with all sorts of things, like cancers. So, the point of
this is to try and take what is a very careful, basic look at the
underpinnings of the immune system, but then extend it all the way out
to figuring out how best to treat people that are coming into the
clinic," her says.
It's estimated more than 33 million people
are now living with HIV/AIDS. More than 10 million of them are also
believed to be infected with tuberculosis. TB is the cause of death for
many of them. The CDC, US Centers for Disease Control, says since 1990,
TB infection rates have increased four-fold in countries with high
rates of HIV.
World TB Day is March 24th.

Antiretrovirals Reduce AIDS Deaths, But Some Illnesses Remain Serious
People
who begin antiretroviral (ARV) therapy before their CD4 cells drop
below 200 have a significantly reduced risk of developing an
AIDS-defining opportunistic illness (OI), but some OIs remain deadly...
March 11, 2009
People who begin antiretroviral (ARV) therapy before their CD4 cells
drop below 200 have a significantly reduced risk of developing an
AIDS-defining opportunistic illness (OI), but some OIs remain deadly,
according to a study published online March 10 in the journal Clinical Infectious Diseases.
Numerous
studies have reported the significant reduction in AIDS-related OIs
since the introduction of combination ARV therapy. While many studies
now focus on the risk of non-AIDS-related diseases that can affect
people living longer with HIV, AIDS-related OIs are still a risk to
some people on ARV treatment. Yet not many recent studies have explored
the most common, and most deadly, OIs among HIV-positive people who
receive ARV treatment and have moderately healthy immune systems.
To
determine the impact of ARV initiation on deaths from AIDS-related
illnesses, researchers with the Antiretroviral Therapy Cohort
Collaboration examined the medical records of 31,620 HIV-positive
patients from 15 cohort studies around the globe. All of the patients
started ARV therapy before December 31, 2004, and none had been
previously diagnosed with AIDS. The average CD4 count before starting
ARV therapy was 256.
Over an average follow-up period of 43
months, 2,262 people developed an AIDS-defining illness and 377 died
after such a diagnosis. The most common illnesses were esophageal candidiasis, Pneumocystis jiroveci pneumonia (PCP), Kaposi’s sarcoma (KS), pulmonary tuberculosis (TB) and non-Hodgkin’s lymphoma (NHL). The average time from ARV initiation to the development of an AIDS-defining illness was nine months
Though
relatively few people died after being diagnosed with an AIDS-defining
illness, certain illnesses were more likely to be associated with
deaths, including NHL and progressive multifocal leukoencephalopathy (PML). Diseases with a moderate risk of death included disseminated Mycobacterium avium complex (MAC), AIDS dementia complex, toxoplasmosis and cryptococcosis. All other diseases had a low risk of death among patients using ARV therapy.
The
authors acknowledge that because of the way that records were kept,
they could not be certain that people who died after diagnosis of an
AIDS-defining illness actually died directly as a result of that
illness, rather than some other cause. Thus the magnitude of the risk
of death could be somewhat lower than recorded for some of the
illnesses listed above.

Bio-Alcamid Blues: Possible Problems With a Facial Wasting Treatment
Bio-Alcamid,
a popular treatment for facial wasting, is being scrutinized due to
increasing reports of long-term complications. AIDSmeds investigates
the risks for Bio-Alcamid patients.
March 17, 2009
Cosmetic doctors and activists say that people treated with
Bio-Alcamid, a popular facial and buttock area filler for people with
HIV and lipoatrophy, may end up with complications months or years
after treatment. Online forums and message boards have been collecting
more and more Bio-Alcamid complaints in recent years, including
migration of the filler from the cheeks to the jowls and serious
infections requiring heavy-duty antibiotic therapy and surgical removal
of the product. At the same time, a leading cosmetic dermatologist
sounding the alarm regarding Bio-Alcamid stresses that there’s no need
for those who have been injected with the filler to panic.
Not
yet approved in the United States—though an application has been
filed—the gel-based Bio-Alcamid (polyalkylimide) was at one time a
popular product used to permanently replump sunken facial and butt
cheeks in people with HIV. According to Luis Casavantes, MD, a highly
respected dermatologist from the Center for Cosmetic and Reconstructive
Dermatology in Tijuana and Puerto Vallarta, Mexico, several thousand
people spent a great deal of money to travel to other countries for
treatment.
Now, some people who achieved their dream of a full
and healthy-looking face after being injected with the product have
instead begun to deal with what they call a nightmare—and Casavantes,
who once touted the wonders of Bio-Alcamid, has publicly written to a
British medical board urging it to recommend against the product’s use
for people with HIV.
Casavantes is well known to many
HIV-positive Americans who ventured south of the border for solutions
to facial wasting. Thus, lipoatrophy treatment advocates and patients
took notice when he published his letter to the National Institute for
Health and Clinical Excellence (NICE) in London—which judges the cost
effectiveness of treatments and has power over what treatments the
United Kingdom’s National Health Service will cover. In his recent
letter to NICE, he wrote: “I am at a loss for words when it comes to
describing the numbers of different sorts of horrendous complications
arising from the use of Bio-Alcamid and of the personal devastation
wrought on the lives of these people.”
In his own practice,
Casavantes estimates that as much as 15 percent of his patients who
received Bio-Alcamid injections experienced complications. The Italian
company Polymekon, the maker of Bio-Alcamid, claims that the actual
rate of complications caused by the gel itself is less than 1 percent
and that most of the reports it has seen likely involved poor
administration of the product or subsequent procedures, such as dental
work, that introduced bacteria into the implants. The company also
claimed that the product does not migrate. Unfortunately, published
data on Bio-Alcamid complications are scarce.
Even if rates of
complications are as high as Casavantes believes them to be, the vast
majority of people will not have problems. “You shouldn’t live in
fear,” he says, adding that he never meant to alarm people with his
letter. Rather, given the alternatives available today, he wants to
make sure that people turn to those treatments rather than Bio-Alcamid.
For people who’ve already been treated, Casavantes and advocates such
as J.J. McMillen, from Houston, say that people can take precautions to
guard against problems, or to catch them quickly.
What’s the Problem?
Polymekon
claims that its product is ideal, because it isn’t absorbed by the body
and it doesn’t provoke the body to forcibly evict its foreign matter.
The company says this makes Bio-Alcamid a permanent filler, compared
with several other products that are eventually broken down and removed
by the immune system. But McMillen, a 47-year-old HIV-positive man who
had Bio-Alcamid treatments in his face in 2004 and a subsequent
infection in 2007, says that doctors have since told him that these
qualities are what potentially make Bio-Alcamid dangerous.
When
many fillers are injected, the body will often enclose them in layers
of scar tissue (collagen) fed by blood vessels and tagged for removal
from the body by the immune system. Not so with Bio-Alcamid. Thus, if
bacteria make their way to the implant, McMillen says, “you don’t have
the benefit of the [immune system] to deal with it.”
Polymekon
might be technically correct in saying that the gel itself does not
cause infections. But the implant might serve as a safe harbor for
infections down the line if bacteria are somehow introduced, such as
through dental procedures that occur very close to the facial areas
where Bio-Alcamid is injected. We depend on our immune systems to
successfully fight off these sorts of infections.
For
Casavantes, this means recommending that people who want a solution for
facial and buttocks wasting turn to implants that aren’t off limits to
the immune system. One possible option is PMMA (polymethyl
methacrylate), another permanent filler Casavantes now uses. PMMA
relies on the formation of collagen and continuous blood flow,
resulting in long-lasting facial filling with protection from the
immune system.
Finding someone to treat infections and remove
the Bio-Alcamid, McMillen says, can be frustrating and difficult.
“[Doctors will] do it if they have to, but they don’t want to, and they
don’t like to,” he says. “A lot of people I’ve talked to on the phone
that have had infections, they can’t get anybody to work on them.”
Unfamiliarity
with the product is one likely reason for this. As McMillen explains,
health care providers will ask, “Why’d you put that stuff in your face?”
Casavantes
says extracting Bio-Alcamid usually isn’t difficult and can be
performed on an outpatient basis. Occasionally though, he says, it can
be more challenging and the facial skin must be lifted off the muscle,
as with a face-lift, which is a far more intensive, potentially painful
and a complicated procedure.
Since people had to leave the
United States to get Bio-Alcamid in the first place, and since leaving
the country to deal with an infection is not usually realistic or wise,
it is up to U.S. surgeons to extract the product and treat the
infections. In fact, Casavantes often consults with U.S. doctors about
Bio-Alcamid extraction.
An Ounce of Prevention: Disclosure and Antibiotics
Both
Casavantes and McMillen urge people who’ve had Bio-Alcamid to inform
all their health care providers about their implants—especially
dentists, dermatologists and plastic surgeons. McMillen says: “The
majority of the complications, the infections that we see with
Bio-Alcamid, [are in] people who went in to have a root canal or other
dental work.”
When dentists inject anesthesia into patients’
mouths, it can introduce bacteria into the Bio-Alcamid. McMillen’s HIV
doctor prescribes an antibiotic for him for the day of, and the day
after, any dental procedure.
McMillen says the second most
common reason for problems with Bio-Alcamid involves people who’ve had
touch-ups to their faces or buttocks with another filler, usually by a
plastic surgeon different from the one who implanted the Bio-Alcamid.
McMillen understands why people “who’ve finally gotten their faces
back” would want to keep looking well, but he urges that they approach
touch-ups with caution.
Larry Smyle, 61, of San Francisco fully
understands the deep and painful repercussions that can come with
HIV-related facial wasting. After participating in the Hawaii AIDS ride
in 2001 and losing a lot of weight, he had a date with someone he’d met
online. “When the guy walked in, he visibly recoiled when he saw me,”
Smyle recalls, “and that’s when I decided that it was time to do
something.”
Smyle says he was one of the first people with HIV
to receive Bio-Alcamid implants in Mexico and, unfortunately, one of
the first to experience problems. First there was dislocation: Some of
the gel had migrated down into his jowls after three years, prompting
him to revisit Mexico to have it removed. His doctor used a needle to
do the extraction by going through the inside of his mouth, which Smyle
describes as “uncomfortable, but tolerable.” Then, to add insult to
injury, Smyle’s cheek became infected days later, requiring a course of
heavy antibiotics.
Don’t Panic!
Casavantes
reiterated that people who have received Bio-Alcamid shouldn’t panic.
Most, he says, won’t have any problems. And if McMillen is right—that
disclosure to other providers, caution about facial trauma and
judicious use of antibiotics can help prevent problems—then most people
who’ve had Bio-Alcamid treatment will probably do just fine in the long
run.
Data would be useful to back up these claims. Activists
might need to call for some kind of cohort, on an international level,
to track what happens, over months and years, to people who’ve been
treated with Bio-Alcamid, and possibly other fillers.
Though
McMillen was pleased with the Bio-Alcamid treatment before the
infection, he has opted to forgo further cosmetic treatment for his
facial wasting. He says, “I finally had to break down and look in that
mirror and see that dent in my face and say, ‘That’s all right, I’m
alive, and I’m enjoying today!’”

Lymphoma Drug Wakes Up Dormant HIV
A
drug approved to treat lymphoma, Zolinza (vorinostat, SAHA) can wake up
CD4 cells latently infected with HIV and render them vulnerable to
antiretroviral (ARV) medication, according to a study published in the
Journal of Biological Chemistry and reported by EurekAlert.
March 17, 2009
A drug approved to treat lymphoma, Zolinza (vorinostat, SAHA) can wake
up CD4 cells latently infected with HIV and render them vulnerable to
antiretroviral (ARV) medication, according to a study published in the Journal of Biological Chemistry and reported by EurekAlert. Activating these dormant cells is a goal for researchers
who hope to find ways to either eradicate the virus or help the body
control HIV infection without ARV therapy.
Scientists have
experimented with several different drugs to try to wake up dormant
infected cells, but the compounds used were either ineffective or too
toxic. Matija Peterlin, MD, and Xavier Contreras, PhD, from the
University of California in San Francisco and their colleagues had
previously identified a promising drug called HMBA, but they had to
discard it due to likely toxicity. A related drug, Zolinza, however, is
already approved for lymphoma and has a well-known side effects profile.
Peterlin,
Contreras and their colleagues found that Zolinza was able to wake up
dormant cells, both in laboratory cell cultures and in blood taken from
people on ARV medication. The next step will be to explore the
treatment in people on ARV therapy.
Zolinza’s most serious
side effects can include blood clots in the legs and lungs, diabetes,
fewer platelets and red blood cells and dehydration from nausea and
vomiting. The drug, however, would likely be used in HIV patients only
for short periods of time.

High rate of anal HPV infection, low rate of clearance and significant new infections in HIV-positive gay men
Anal
infection with human papilloma virus was almost universal amongst
HIV-positive gay men in a Canadian study published in the April 1st
edition of the Journal of Infectious Diseases. The study also found
that there was a high prevalence of infection with cancer-associated
strains of human papilloma virus and that few men cleared such
infections in the course of the study.
March 17, 2009
Anal infection with human papilloma virus was almost universal amongst
HIV-positive gay men in a Canadian study published in the April 1 st edition of the Journal of Infectious Diseases.
The study also found that there was a high prevalence of infection with
cancer-associated strains of human papilloma virus and that few men
cleared such infections in the course of the study.
Furthermore, during the three years of the study a significant
proportion of men became infected with strains of human papilloma virus
associated with a high risk of pre-cancerous and cancerous cell changes
in the anus.
The findings of the study are likely to inform the emerging debate
about the value of providing HIV-positive individuals with the
recently-approved vaccines for human papilloma virus. Although the use
of these vaccines is only approved for girls in their early teens, some
HIV physicians are privately speculating that it may be worthwhile
screening their patients for infection with strains of human papilloma
virus associated with a high risk of anal and cervical cancer and
administering the vaccine to patients who are not infected.
HIV-positive gay men are significantly more likely to develop
pre-cancerous and cancerous cell changes in their anus than
HIV-negative gay men. HIV treatment does not appear to offer direct
protection against the development of anal cancer.
Development of pre-cancerous and cancerous cell changes in the anus is
strongly associated with certain strains of human papilloma virus.
Previous research has found a high prevalence of anal infection with
human papilloma virus in HIV-positive gay men, but there is little
information on the natural history of such infections in this
population.
Canadian researchers from the HIPVIRG (Human Immunodeficiency and
Papilloma Virus Research Group) therefore designed a three year
prospective study involving 247 HIV-positive gay men to answer this and
a number of other questions.
Men recruited to the study were assessed for infection with human
papilloma virus at baseline and followed-up every six months for three
years for further evaluation. Blood tests were performed to determine
which strains of human papilloma virus patients were infected with.
Demographic information was also obtained, as was information on the
use of HIV treatment, CD4 cell count and viral load.
The mean age of men participating in the study was 43 years. The
average (median) duration of HIV infection was eleven years, and 36% of
men had been diagnosed with AIDS. On entry to the study, the median CD4
cell count was 380 cells/mm 3 and 56% of individuals had an undetectable viral load. A total of 93%
of patients were taking HIV treatment. The mean duration of follow up
was 31 months. After 24 months of follow up, median CD4 cell count had
increased from baseline to 480 cells/mm 3.
Testing conducted on entry to the study showed that almost all (98%) of
the men had anal infection with human papilloma virus. Of the five men
not infected at baseline, three acquired anal human papilloma virus
infection during the course of the study.
Most of the men (91%) were infected with multiple strains of human papilloma virus (median, five strains).
The most prevalent type of human papilloma virus was the
cancer-associated HPV-16 (38%), HPV-6 infection was present in 35% of
men, HPV-42 in 29%, and HPV-18, another type strongly associated with a
high risk of anal cancer, was present in 25%.
Few of the men cleared the infection. The strain of human papilloma
virus with the lowest clearance rate was HPV-16 (twelve episodes
cleared per 1000 person months). The clearance rate of HPV-18 was 20
per 1000 person months.
There was also a high rate of new human papilloma virus infections in
the study. Over a third of patients uninfected with HPV-16 acquired the
infection during the course of the study, with 13% becoming infected
with HPV-18. No information was provided by the investigators about the
role or otherwise of immune reconstitution in the clearance of human
papilloma virus infection.
"HIV infection not only increases HPV persistence but also increases
the risk of acquisition of new HPV infections and reactivation of
