Children Living with HIV/AIDS Need Access to Specialized Antiretroviral Treatments
Medical News Today
July 27, 2007

Children living with HIV/AIDS in developing countries need access to specialized antiretroviral drugs and other treatments, Annette Sohn, an assistant professor at the University of California-San Francisco's pediatric infectious disease division, said on Wednesday at the 4th IAS Conference on HIV Pathogenesis, Treatment and Prevention in Sydney, Australia, AFP/ reports (Sands, AFP/, 7/25).

Delegates attending the conference, which ends on Wednesday, presented studies and discussed advances in HIV/AIDS prevention and treatment. The conference aims to improve understanding of HIV/AIDS, treatments for the disease and methods to prevent it from spreading worldwide (Kaiser Daily HIV/AIDS Report, 7/24).

According to Sohn, about 780,000 HIV-positive children worldwide need antiretroviral drugs but only 15% have access to them. Sohn urged pharmaceutical companies to focus on designing specialized antiretrovirals for children after a study -- which was conducted by NIH's National Institute of Allergy and Infectious Diseases and found that HIV-positive infants have a greater chance of survival if they are given immediate treatment -- was presented at the conference on Wednesday (AFP/, 7/25).

The NIAID study began in 2005 and was conducted in Cape Town and Soweto, South Africa. It examined 337 infants ages six to 12 weeks and initially aimed to determine whether early antiretroviral drug therapy over a limited time period would postpone HIV progression, Reuters reports. The study found that 96% of infants given immediate drug treatment were alive two years after birth, compared with 84% of the children given treatment later (Perry, Reuters, 7/24).

An independent safety and monitoring board in London last month said that the study's results were so convincing that the study should be changed to allow all the infants to receive treatment and that the early results should be released (Foley, AP/South Florida Sun-Sentinel, 7/25).

Kevin De Cock, director of the HIV/AIDS Department at the World Health Organization, at the conference said the study is "obviously immensely important in its insight into pediatric treatment strategies," adding, "But the data will need to be looked at more before we really say what the implications are for treatment policy." Current WHO policy says that drugs should be administered only after children demonstrate signs of a weakening immune system. According to De Cock, "You can't scale up therapy or provide appropriate treatment to people if they don't know their HIV status." He added, "There's a need across the board to scale up HIV testing" (Foley, Associated Press 7/25).

"Children with HIV infection frequently show rapid disease progression within the first year of life due to their developing immune system and susceptibility to other serious infections," NIH Director Elias Zerhouni said Wednesday when releasing the study at the conference. He added, "This is the first randomized clinical trial that shows that infants treated before three months of age will do better than infants who have their treatment delayed." Anthony Fauci, director of NIAID, said, "The results of this trial could have significant public health implications worldwide because these findings will cause experts to consider changes in standards of care in many parts of the world" (Reuters, 7/24).

Sohn on Wednesday said, "These findings have implications for guidelines on timing of antiretroviral therapy in early infancy and support the need for enhanced early diagnosis of infants and early effective transition into care." She added, "Research presented at this and other conferences have increasingly proven that we are waiting too long to treat HIV-positive children" in developing countries. According to Sohn, "Better generic pediatric antiretrovirals that are both potent enough to achieve sustained clinical and virological improvement and have limited long-term metabolic side effects are urgently needed." Better diagnostic tools for health care workers working on pediatric HIV also are needed, Sohn added. "We are not identifying more HIV-positive women during pregnancy, and we lack the ability to diagnose their infants, so we don't know they're infected until they're already very sick," she said, adding, "By that time, it's often too late to prevent opportunistic infections and maximize the treatment benefits of antiretroviral therapy" (AFP/, 7/25).

Citric Juice, Microbicide Studies
Roger Short, a reproductive biologist at the University of Melbourne, at the conference Tuesday presented a study that found vaginal douching with citrus juice has no effect on the spread of sexually transmitted infections, including HIV, Australia's The Age reports (Leung, The Age, 7/24). Short in 2002 told the Australian Broadcasting Corporation that a "few drops" of lemon or lime juice could protect women from HIV infection and unplanned pregnancies. He said he thought HIV, in addition to sperm, also might be affected by lemon juice because the virus is "extremely susceptible" to acidity. According to Short, laboratory tests, which did not include tests on humans or animals, indicated that the citrus juice killed HIV and sperm (Kaiser Daily HIV/AIDS Report, 10/11/02).

The recent study, conducted in collaboration with clinicians in the U.S. and Nigeria, examined the sexual health of almost 400 commercial sex workers in Jos, Nigeria. About one-fifth used lemon or lime juice to prevent STIs while the others did not. Tests for STIs -- including HIV, syphilis and hepatitis B and C -- found that there were no statistically significant differences in incidence between the groups, The Age reports. "Unfortunately, [lemon and lime juice] doesn't appear to have worked" in preventing STIs, Short said (The Age, 7/24).

Also at the conference, Jeremy Paull, a researcher at the Australian pharmaceutical company Starpharma, presented data from recent trials of an experimental microbicide, called VivaGel, that has been found to prevent the sexual transmission of HIV and genital herpes, the AAP/Sydney Morning Herald reports. According to Paull, recent trials on animals have shown the gel to be between 85% and 100% effective at preventing the transmission of HIV and genital herpes. He added that the active ingredient in the gel is dendrimer, which is a molecule that binds to both viruses and prevents them from infecting healthy cells. Safety trials of the gel are under way among humans, the AAP/Morning Herald reports. According to Paull, the gel will be used by men who apply it before sex with women. Initial data presented at the conference indicate that the gel is safe and well-tolerated by healthy men whether or not they are circumcised (AAP/Sydney Morning Herald, 7/25).

In related news, conference delegates also discussed the risks people living with HIV/AIDS face as their lives are extended by the use of antiretrovirals, Business Day/ reports. Physicians speaking at the conference warned that while HIV-positive people are living longer, they face a higher risk of age-related illnesses, including cardiovascular disease, osteoporosis and dementia (Kahn, Business Day/, 7/24). serves as the official webcaster of the IAS conference.

PBS' "The Charlie Rose Show" on Tuesday included a discussion about developments in HIV/AIDS research. Guests on the program included biochemist and Nobel Prize winner Paul Nurse; Seth Berkley, president and founder of the International AIDS Vaccine Initiative; Scott Hammer, a professor of medicine at Columbia University; Peter Kwong of the Vaccine Research Center at NIAID; and Judy Lieberman, director of the Division of AIDS at Harvard Medical School and senior investigator at the CBR Institute for Biomedical Research (Rose, "The Charlie Rose Show," PBS, 7/24) Video of the segment will be available online later this week.

BMS Launches New Approach to Expanding HIV Treatment Model
Bristol-Myers Squibb at the conference on Monday announced a new approach to expanding its Secure the Future initiative in developing countries. The new approach will replicate the initiative's HIV/AIDS treatment support programs in conjunction with governments, community groups and other funders. Secure the Future at the conference released a manual on establishing antiretroviral treatment programs that include community support to ensure that HIV-positive people receive assistance at home and in the community, as well as in clinics. The manual includes experiences from Botswana, Lesotho, Namibia, Swaziland and South Africa (BMS release, 7/23).
