Anal sex HIV risk misunderstood among heterosexuals

DURBAN , 21 June 2011 (PlusNews) - Vaginal sex, thigh sex, even armpit sex - people have sex in lots of ways, but in heterosexual anal sex, HIV prevention programming is silent about the high risk of infection that goes with it, and people may have mistaken this silence for safety.

The risk of contracting HIV through unprotected receptive anal sex is almost 20 times greater than the HIV risk associated with vaginal intercourse.

While this fact is often a focus in HIV prevention programming aimed at men-who-have-sex-with-men (MSM), it has been largely left out of programmes for heterosexuals, according to Zoe Duby of the University of Cape Town, South Africa, and the Desmond Tutu HIV Foundation.

Duby presented the findings of her study, which interviewed almost 400 people in Tanzania , Uganda and Kenya , at the 1st HIV Social Sciences and Humanities Conference held recently in Durban , South Africa .

“Safer sex programming has, in my opinion, failed to take into account varying definitions of sex. The omission of anal sex in safe sex messaging has been interpreted as meaning that anal sex is safe,” she told IRIN/PlusNews.

“What people preach out there, it’s just vaginal sex - not information on anal [sex],” said a young woman from Salgaa , Kenya , who was quoted in the research. “So somebody thinks, ‘if I do [sex] this other way, then I will not get HIV.’”

Even more worrying was that research showed healthcare workers often held similar views, and some incorrectly believed HIV was only present in vaginal fluid. The virus is, in fact, also present in male sperm and blood.

“Me, I do not want to practice vaginal sex because that is the highest [risk] sex that transmits HIV, so it is a belief… that non-vaginal sex does not transmit HIV,” one Kenyan healthcare worker reported.

A nurse in Malaba , Uganda , said: “As you go and have sex vaginally you can get HIV, but these other methods, they do not expose you [to HIV].”

Virginity, pregnancy and pleasure

East African respondents said anal sex was also practiced as a way to prevent pregnancy, increase sexual pleasure, or preserve a woman’s virginity, which was only associated with vaginal sex.

“A lady got married a real virgin… and then she started showing symptoms of HIV. When she was questioned… she started crying, saying that she was advised to only have anal sex so that she would still maintain her virginity and respect during marriage,” a Kenyan truck driver said during an interview.

“Youth today are searching for these things that don’t make them lose their virginity but allow them to still sort of engage in sexual activity,” according to another young woman. Anal sex is seen as a cultural “loophole”.

“My religious friends who are trying to hold onto some sanctity of waiting until they’re married to have sex, they feel that oral and anal sex are sex that they can have that’s still not full sex,” a female respondent told Duby.

She said research about the use of anal sex to preserve virginity has noted similar views among young South African women, especially in communities that practice virginity testing.

Safe sex messaging

Duby cautioned that her results - part of a Family Health International evaluation of an HIV programme for mobile populations - should not be generalized, but did show that anal sex must be included HIV prevention programming.

“Sex has largely been defined as penile-vaginal penetrative sex… We hear this word ‘sex’ bandied about all the time but… we’re not really looking at… how [people] are defining it in order to tailor safe sex messaging.” she told IRIN/PlusNews.

“Due to the assumptions that sex refers to penile-vaginal penetration only, people put themselves at a greater risk of contracting HIV in an attempt to practice safe sex,” Duby added. “Unprotected anal sex can no longer be ignored as a significant contributing factor in the global HIV epidemic.”

New guidelines on HIV programming for MSM

NAIROBI, 22 June 2011 (PlusNews) - HIV and gay rights activists say new guidelines released by the UN World Health Organization (WHO) on HIV programming for men who have sex with men (MSM) will not only improve health service provision for MSM, but will also act as an advocacy tool in the fight for the rights of this marginalized population.

"The document provides well-researched and evidence-based recommendations for HIV prevention and treatment of MSM, which will be useful for clinicians," said Kevin Rebe, a doctor with Health4Men, a South African health service provider which caters specifically for MSM. "The language of the paper is couched in human rights, and makes a strong call for decriminalization of same sex sexual activity, so it will also be useful for activists seeking to end discrimination."

The guidelines are designed for use by national public health officials and managers of HIV/AIDS and STI (sexually transmitted infections) programmes, NGOs and health workers. They contain MSM-specific programme activities such as the use of water- and silicone-based lubricant for the correct functioning of condoms during anal sex.

The guidelines do not advise medical male circumcision - a measure WHO recommends for HIV prevention among heterosexual men - for HIV prevention among MSM due to the lack of sufficient research on its effect of its use in MSM sexual activity.

They further recommend that health services adhere to the principles of medical ethics and the right to health, and ensure that MSM feel comfortable enough to seek medical care, with MSM-specific health needs catered for within national health systems.

"Like many other African countries, all men in South Africa are assumed to be straight, so health workers are not aware of the need to identify people of different sexualities during consultations; outside of centres like ours, there is little competency in providing health care to MSM," said Rebe. "By availing this knowledge, the guidelines will empower health workers to provide better care to MSM."

Wake-up call

In countries like Uganda, where homophobia is deeply entrenched both within society and the law, gay rights groups hope the new guidelines will serve as a wake-up call to the government about the need to include MSM in HIV programming.

"I hope the new guidelines will be an eye-opener to the government, who have so far ignored MSM within HIV prevention, treatment and support; it should show them that MSM exist in Uganda and are at high risk," said Frank Mugisha, executive director of the NGO Sexual Minorities Uganda. "They therefore cannot be ignored and urgently require HIV interventions."

Mugisha noted that the WHO document added to growing pressure from other international organizations calling for MSM to be included in HIV programmes - including UNAIDS and the Global Fund to fight AIDS, TB and Malaria - and would hopefully persuade the Ugandan government to change its policies.

According to WHO, criminalization of same-sex sexual activity plays a key role in the vulnerability of MSM and transgender people to HIV; more than 75 countries currently criminalize same-gender sexual activity.

Rebe noted that even in countries like South Africa , where MSM had their human rights enshrined in the law, widespread stigma and ignorance about their needs existed, even within the medical fraternity.

"Rights on paper only"

"These [MSM] rights are very much rights on paper only, they are not guaranteed; homophobia remains widespread, with politicians frequently making openly homophobic statements," he added. "If used widely, these guidelines have the potential to help reduce stigma and improve the level of care MSM receive."

Policymakers say the guidelines will help to inform planned HIV programming for MSM. "One of the biggest problems we have for MSM seeking health care is the attitude of health workers - these guidelines will build on the body of knowledge we have on supporting this group," said Nicholas Muraguri, head of Kenya 's National AIDS and STI Control Programme.

Muraguri noted that although the Kenyan penal code still criminalized same sex sexual activity, the Constitution's Bill of Rights laid out the right of every Kenyan to health.

"MSM don't live on the outside of society, they live with us and deserve the same treatment as other members of society; recent studies show that in Kenya MSM HIV prevalence is as high as 25 percent - and many of these men are married and have girlfriends, so ignoring them is totally impractical," he said. "HIV programming for MSM is not a matter of choice - it is a necessity."

AIDS drugs can cause premature ageing: study

LONDON Jun 26, 2011

(Reuters) - A class of generic AIDS drugs often used to treat HIV in Africa and other poor regions can cause premature aging and lead to age-related illnesses such as heart disease and dementia, scientists said on Sunday.

In a study in the journal Nature Genetics, British researchers found that the drugs, known as nucleoside analog reverse-transcriptase inhibitors, or NRTIs, damage DNA in the patient's mitochondria -- the "batteries" that power cells.

The scientists said it was unlikely that newer cocktails of AIDS drugs made by firms like Gilead , Merck, Pfizer and GlaxoSmithKline would inflict similar levels of damage, since they are thought to be less toxic to mitochondria. But more research is needed to be certain.

"It takes time for these side effects to become apparent, so there is a question mark about the future and whether or not the newer drugs will cause this problem," Patrick Chinnery of the Institute of Genetic Medicine at Newcastle University said in a telephone interview. "They are probably less likely to, but we don't know because we haven't had time to see."

The findings do however help explain why HIV-infected people treated with older antiretroviral AIDS drugs sometimes show advanced signs of frailty and diseases such as heart disease and dementia at an early age, the researchers said.

"The DNA in our mitochondria gets copied throughout our lifetimes and, as we age, naturally accumulates errors," said Chinnery, who led the study.

"We believe these HIV drugs accelerate the rate at which these errors build up. So over the space of, say, 10 years, a person's mitochondrial DNA may have accumulated the same amount of errors as a person who has naturally aged 20 or 30 years."

NRTI drugs -- the best known of which is AZT, also known as zidovudine and originally developed by GSK -- were a big advance in HIV treatment when they first emerged in the late 1980s. They extended patients' lives and helped make HIV a manageable chronic disease rather than the death sentence it once was.

Concerns about toxicity of NRTIs, particularly with long-term use, mean the drugs are now less commonly used in wealthy countries where they have been replaced by newer more expensive combination AIDS drugs with fewer side-effects.

But in poorer countries, where access to cheaper generic medicines is often the only option for HIV patients to get treatment, NRTIs are still relatively widely used.

An estimated 33.3 million people worldwide had the human immunodeficiency virus (HIV) that causes AIDS in 2009, according to the latest United Nations data, and 22.5 million of those live in Africa .

"These drugs may not be perfect, but we must remember that when they were introduced they gave people an extra 10 or 20 years when they would otherwise have died," said Brendan Payne of Newcastle 's Royal Victoria Infirmary, who also worked on the study.

"In Africa , where the HIV epidemic has hit hardest and where more expensive medications are not an option, they are an absolute necessity."

For their study, Chinnery's team studied muscle cells from HIV-infected adults, some of whom had previously been given NRTIs. They found that patients who had been treated with NRTIs -- even as long as 10 years previously -- had damaged mitochondria similar to that of a healthy older person.

The researchers are now looking at ways to repair or stall some of the damage caused by the drugs and say they believe that focusing on exercise -- which appears to have a beneficial effect on patients with mitochondrial diseases -- may help.

Poor adherence threatens paediatric ARV programme

24 Jun 2011 09:55

Source: Content partner // IRIN

NAIROBI , 21 June 2011  - As Kenya puts more HIV-positive children on life-prolonging antiretroviral (ARV) drugs, experts are warning that unless more effort is put into ensuring the medicines are taken regularly, widespread treatment failure could result.

"It is very hard to maintain adherence in children because they rely on others to give them medicine, some change regimens as they grow into adolescence and they can hardly cope with the many drugs they are expected to take," said Dr Andrew Suleh, medical superintendent at the Mbagathi District Hospital in the capital, Nairobi.

HIV-positive children - depending on their weight - can take up to four ARV pills a day; by the age of 15, a child may have taken upwards of 25,000 ARV tablets.

"You are faced with a situation where, even when they fail first-line [treatment] and you initiate second-line, success is not guaranteed because the factors [that hamper adherence] still exist," Suleh said.

Treatment failure occurs when first-line medication can no longer control HIV infection. Patients are then usually put on second-line drugs, but these are not only less accessible than the first-line option, they are often also several times more expensive.

According to the government, an estimated 184,000 children were living with HIV by the end of 2009; 24 percent of those requiring ARVs had access to them. Kenya is making gains in terms of the number of children on HIV treatment - 20,500 were on ARVs in 2008, growing to 28,000 by 2009. About 1,500 children are on second-line ARV regimens but officials do not have a figure for the number of children in need of second-line drugs.

Joy*, 11, has been on ARVs for nearly two years. She was orphaned several years ago and has been passed from relative to relative for most of her life; the constant change of guardians means that her adherence to ARVs has not always been consistent.

"When you look at her case you find she has started to develop rashes and mouth sores, and she has diarrhoea, which are clinical signs that her treatment is failing," said Suleh, who is treating Joy.

Joy's current guardian says she was never fully briefed on the importance of strict adherence to ARVs and Joy has occasionally skipped doses of her drugs.

"I thought she could just take them on her own without being told because she has taken those drugs for long, but when she started falling ill again, she told me wasn't taking them," the guardian said.

The UN World Health Organization (WHO) recommends the use of pill boxes, calendars, diaries and other practical tools to support children's adherence.

Experts say a combination of factors create treatment failure and put children's lives at risk, including poor adherence, long-term use of ARVs, and improper actions by health workers, who may miss or ignore the first signs of treatment failure in children rather than referring them for a change of regimen.

"There are children who are in need of second-line treatment but many are not receiving it. This is not to say that the drugs aren't available, but most health workers have staging fright and adopt a 'wait and see' attitude, or facilities do not request the drugs," says Dr Judith Kose, technical director at the Elizabeth Glaser Paediatric AIDS Foundation.

Other challenges include the fact that some of the drugs - such as Didanosine suspension - recommended by WHO - require refrigeration, which is inconsistent or unavailable in much of rural Kenya . There are also significantly fewer generic second-line formulations available, limiting options after failed first-line therapy.

Officials say the biggest problem is the high cost of second-line drugs, but the government is using adherence monitors to boost treatment success and optimize the first-line option.

Guardians� fear of disclosure also hampers children's adherence. "As a child grows up, they start to ask questions about why they are constantly on treatment yet they look healthy," Kose said. "They wonder why those around them aren't taking medicine, and this at times comes with rebellion where they refuse to take the drugs, eventually."

Creating support networks for HIV-positive children and educating guardians about systematic disclosure were some of the ways to improve adherence in children, Kose suggested.

"It is not just about health workers or guardians,� she said. �This calls for community support from the schools they go to, even sensitizing their friends to support them in taking the drugs."

Cost of AIDS drugs to keep falling: experts

By Pierre-Antoine Donnet (AFP) – Jun 7, 2011

UNITED NATIONS — The cost of drugs used to keep AIDS at bay will keep falling because of the huge demand from millions of sufferers desperate for the lifeline, experts said at the United Nations on Tuesday.

But nations still wrangled ahead of a major three day AIDS summit over how many people will get treatment in coming years.

The summit of about 30 presidents and government leaders must set the future direction of global AIDS policies. Pop stars such as Alicia Keys and Annie Lennox joined pressure groups in demanding rich nations pay the money needed to treat millions more sufferers.

The market economy will drive down the prices of the retrovirals used to keep millions alive now, according to Morolake Odetoyinbo, a board member of the Global Fund to fight AIDS, Tuberculosis and Malaria from Nigeria .

The cost "can only keep falling because they are trying to get more people on treatment, which means there is a bigger demand and that big demand will drive down the prices," she told AFP.

Odetoyinbo, founder of the Positive Action for Treatment Access group in Nigeria , stressed that it was imperative to reduce the cost of treatment to get more people onto the life-saving drugs.

There are an estimated 34 million people living with AIDS and more than nine million are still not getting treatment, according to UN statistics. About 6.6 million people are getting drugs and the rest do not know they have AIDS.

The annual cost of retrovirals was about 10,000 dollars in 2001 but has tumbled to about 67 dollars a year, according to Sharonann Lynch, an expert for the Medecins Sans Frontieres, or Doctors Without Borders, group.

"Cost is unfortunately the over-riding factor in terms of whether indeed we will be getting the remaining nine million people on treatment who need it today in order to live," Lynch said.

"The question of cost is so important that it's actually driving poor decisions in terms of whether governements participating will take the necessary steps and make the necessary financial investments so that we can finally break the back of this epidemic," the expert said.

Going into the summit, no agreement had been reached on the final communique which was to set the numbers who will receive treatment and how it will be paid for.

The UN Security Council on Tuesday passed a resolution calling for a coordinated international response to the AIDS pandemic, which it said was a threat to international peace and security.

But pressure groups said rich countries -- Europe and North America -- were not ready to pay up for the UN target of getting 15 million people on treatment by 2015. An estimated six billion dollars a year will be needed to fund the extra drugs.

France is leading the negotiations for the European Union, which insists it has taken a "respectable" position in the AIDS talks.

In a sign of the anger of many non-government groups, the AIDES and Act Up Paris groups accused France and Europe of "murderous duplicity" by signing up to a target of getting treatment to at least eight million people but refusing to promise finance.

Celebrities have also spoken out strongly in the AIDS campaign.

"Negligent non-action as a response to the HIV-AIDS epidemic, as it affects women and girls is just as bad, just as accountable as criminal action," said Scottish singer Annie Lennox told a symposium on women and AIDS at the UN headquarters.

American star Alicia Keys said world leaders had the means to save millions of lives in Africa . "The question is are we going to do it or not?"

Docs overtesting for cervical cancer virus

By LAURAN NEERGAARD, AP Medical Writer – 20 June, 2011

WASHINGTON (AP) — Too many doctors are testing the wrong women, or using the wrong test, for a virus that causes cervical cancer.

The days of one-size-fits-all screening for cervical cancer are long gone. How often to get a Pap smear — and whether to be tested for the cancer-causing HPV virus at the same time — now depend on your age and other circumstances.

But a government study reports Monday that a surprising number of doctors and clinics aren't following guidelines from major medical groups on how to perform HPV checks, suggesting a lot of women are getting unnecessary tests.

That wastes money and could harm women who wind up getting extra medical care they didn't need, says Dr. Mona Saraiya of the Centers for Disease Control and Prevention, who led the research.

Even she wasn't protected from the confusion. Saraiya was stunned to get a bill showing that her own doctor had ordered testing for HPV strains not connected to cervical cancer.

The findings, reported in the journal Obstetrics & Gynecology, show women have to be savvy to ensure they're getting the right checkups — enough, but not too much.

"It's extremely discouraging," says Debbie Saslow, gynecologic cancer director at the American Cancer Society, who's had to argue with her doctor against testing too often. "We have not been able to get that message across."

Cervical cancer grows so slowly that Pap smears — which examine cells scraped from the cervix — usually find it in time to treat, or even to prevent when precancerous cells are spotted and removed.

For decades, Paps were the only way to screen for cervical cancer. Now doctors know that certain strains of HPV, the human papillomavirus, cause most cervical cancer. HPV testing isn't a replacement for the Pap. But it can provide extra information to help determine if a woman is at higher or lower risk and thus guide her ongoing care — if it's used correctly.

The new CDC study, part of a national survey of medical practices that included 600 providers of cervical cancer screening, examined how doctors are using it.

The study found 60 percent of doctors and clinics say they give a routine Pap-plus-HPV test to women who are too young for that combination. Guidelines stress that so-called co-testing is only for women 30 and older. If both tests are negative, they can wait three years before their next screening.

Why the age limit? Saslow says HPV is nearly as common as the common cold, especially in younger women — but their bodies usually clear the infection on their own and only a years-long infection is risky. Learning that a 20-something has HPV increases the odds of more invasive testing that in turn can leave her cervix less able to handle pregnancy later in life. Younger women are supposed to get HPV testing only if a Pap signals a possible problem and doctors really need the extra information.

Then there's the question of which test to use. Only a few so-called high-risk strains of HPV cause cervical cancer, the strains doctors are supposed to test for. Before scientists understood the different HPV types, a test already was on the market that detects strains that can cause genital warts, not cervical cancer. The CDC's Saraiya says there's no reason to use that old test because learning you have a probably transient warts-causing strain doesn't alter your care.

Yet her study found 28 percent of doctors and clinics say they order tests for both the cancer-causing and warts-causing strains, regardless of patient age. The study couldn't tell why, although Saraiya says some doctors don't know there's a difference and some order forms for the lab tests don't differentiate.

An HPV test costs $80 to $100, on top of a $40 Pap. Saraiya says labs can bill for two HPV tests when doctors order testing for both kinds of strains.

So what does a woman need to know before her next checkup? The CDC has developed a consumer-friendly brochure to help women understand their options for cervical cancer screening: http://tinyurl.com/6g8de6v

And guidelines from the American College of Obstetricians and Gynecologists recommend that:

—Routine Paps start at age 21.

—Most women in their 20s get a Pap every two years.

—Women 30 and older wait three years between screenings if they've had a negative Pap and negative HPV test, or three consecutive clear Paps.

—If a Pap is inconclusive at any age, HPV testing may help rule out who needs further examination and who can just repeat a Pap in a year.

—Anyone who's been vaccinated against HPV, a relatively new vaccine, still must follow Pap screening guidelines for their age group.

—Higher-risk women, such as those with HIV or previous cervical abnormalities, need more frequent screening.
