HIV Cases in Iowa Increasing
According to the Press-Citizen, unsafe sexual practices among the state's young adult population have contributed to the spread of HIV and the number of sexually transmitted infections. Jeff Meier, associate director of the AIDS Clinical Trial Unit at University Hospitals, said that most of the cases among young people are in the non-student population. "HIV tends to run in circles of poverty, drugs and commercial sex," he said, adding, "There is obviously much less of that in the student population." Meier added that promoting condom use is just a part of a necessary comprehensive prevention strategy.
Randy Mayer -- chief of the Bureau of HIV, STD and Hepatitis at the department of public health -- said that HIV testing at publicly funded sites in the state has decreased since 1992, although HIV prevalence has increased over the same time. For 10 years, about 30% of people in the state have reported ever receiving an HIV test. One reason young people might not be getting tested is a lack of information about cost and availability, the Press-Citizen reports. Tricia Kitzmann, deputy director of the Johnson County health department, said that she hopes to see an increase in testing as the department adheres more closely to state recommendations that encourage frequent HIV testing for the entire population, instead of only populations considered to be high-risk (Carney, Iowa Press-Citizen, 5/11).
Africa Should Manufacture Its Own Antiretrovirals
According to Gawanas, economies in Africa would benefit from the local production of generic antiretrovirals. She added although a large portion of HIV-positive people in Africa do not have drug access, a few countries have made progress in terms of treatment. "Some countries in Africa now have 80% of people with HIV/AIDS on antiretroviral drugs," Gawanas said, adding, "But if there are cuts (in support from donor countries) can that progress continue? We need to mobilize local production" (Malone, Reuters UK, 5/7).
Researchers Developing Pasteurization Technique To Help HIV-Positive Women Breastfeed
VOA News on Thursday examined a project to help HIV-positive women in developing countries breastfeed their infants and reduce the risk of mother-to-child transmission. According to VOA News, some HIV-positive women often face a difficult decision of whether to breastfeed their children, especially in resource-limited countries where formula feeding presents health risks.
In an effort to help make breastmilk safer for infants born to HIV-positive women, Sera Young of the University of California-Davis is working with about 100 women in Tanzania and teaching them to pasteurize their milk at home through flash heating, or a double-boiling method. Young said that "as soon as the water boils, the milk has reached a hot enough temperature -- about 70 degrees Celsius -- to kill all of the HIV but maintain most of the integrity of the nutrients and the immunological properties." She adds that she hopes to learn whether women would be willing and able follow every step in the technique. According to Young, she has observed that women are able to follow it but added that women who feared revealing their HIV-positive status had more issues with the process, as people wondered why they were boiling their breastmilk.
According to Young, although the World Health Organization recommends that HIV-positive women self-pasteurize their milk, it previously was not known whether women found it feasible or acceptable to do so. She noted that researchers are planning to conduct a large clinical study that will provide the "statistical power to look at the differences between those children who received flash-heated milk and those who haven't," adding that knowing the health implications is crucial for HIV-positive women and their children (Hoban, VOA News, 5/7).
HIV Cases Increasing in Britain, UNICEF Report Says
One in 10 new HIV cases in 2007 was recorded among young people ages 16 to 24, and this group also accounted for nearly half of the 40,000 new sexually transmitted infection cases recorded that year. More than four in 10 new HIV cases were recorded among MSM, and Metro reports that cases recorded among this group continue to increase. Tiessen said that Britain's "sizeable" immigrant population from sub-Saharan African might be contributing to the country HIV/AIDS figures; however, she added that sexual behavior among young people also is a key factor and urged government officials to lead "youth-friendly" prevention campaigns. The Department of Health said it will continue funding for organizations such as the Terrance Higgins Trust and the African HIV Policy Network, which target at-risk groups such as MSM and immigrants (Attewill, Metro, 5/7).

Eliminate HIV
‘UNIVERSAL VOLUNTARY HIV TESTING WITH IMMEDIATE ANTIRETROVIRAL THERAPY AS A STRATEGY FOR ELIMINATION OF HIV TRANSMISSION: A MATHEMATICAL MODEL’
In November 2008, an article was published in the renowned medical journal, the Lancet. The article is co-authored by Reuben Granich, Kevin de Cock and Charlie Gilks. The authors of the article are leading members of World Health Organization (WHO) HIV and TB team, but the study is an independent work that has not been endorsed by the WHO. Based on computer modeling, the authors argued that universal HIV testing, followed by the immediate initiation of ART for those who were HIV-positive, could virtually eliminate HIV transmission in the future and reduce the number of people developing AIDS by 95%.
The article aroused heated debate amongst HIV activists, healthcare workers, scientists and officials at organizations like UNAIDS and the World Health Organization (WHO). The debate focused on the human rights implications of the implementation of universal mandatory testing, the potential criminalisation of HIV transmission, and the lack of consideration given to the negative outcomes proven to be associated with universal mandatory HIV testing. However debaters agreed that it is essential that new information that presents the possibility of a solution to HIV epidemic must be seriously considered and researched.
HIV-Positive People at Increased Risk of New Flu Strain
According to WHO, countries with high HIV/AIDS burdens, many of which are in Africa, should ensure that vulnerable people have drug access, including to medicines such as Tamiflu and Relenza. The agency added that it is best if people with the flu strain take antiviral drugs within 48 hours of the onset of symptoms. In addition, there are no known issues with taking flu medications with antiretroviral drugs, according to WHO (MacInnis, Reuters India, 5/2).
Life Insurance for HIV-Positive People
Kevin Carr, director of protection development at PruProtect, said, "We are pleased to be the first mainstream insurer to provide life cover for people living with HIV," adding "I believe it is better to provide some cover for some people than nothing at all." The Terrence Higgins Trust said, "We welcome this move from PruProtect and are glad to see an insurer who recognizes the reality of living with HIV in the U.K. in the 21st century." The group added that it "hope[s]" the program "will be the start of a wider move to offer appropriate financial products to people with HIV" (Simon, Daily Telegraph, 4/29).
Australia Harm Reduction Strategies Serve as Model for Other Countries
Rao said that Australia has called on Asian states to increase harm-reduction programs and examine current drug laws, especially in those states where penalties for drug users can include the death penalty. Rao said, "Australia is a good model for harm reduction programs and also for looking at drug laws and revamping them. In fact, quite a few countries in Asia have learned their harm reduction strategies in good examples from Australia." Parliamentary Secretary for International Development Assistance Bob McMullan said that it is still possible for countries to adopt effective prevention and harm reduction strategies to combat HIV without encouraging drug use. He said that a "very big important part of the Australian government policy" is working "strongly" with drug users. He added that "in terms of reducing the spread of HIV, we have to focus on prevention." Rao's comments came as McMullan announced an additional 640,000 Australian dollars, or about $470,000, for nongovernmental organizations working in Asia (Corben, AAP/Sydney Morning Herald, 5/3).
HIV-Positive People in Wales Denied Treatment
The British Medical Association denied that physicians are discriminating against people living with HIV/AIDS and said that some physicians might be more cautious in referring HIV-positive people to specialists. However, Williams said that HIV-positive people are experiencing "very subtle" discrimination, adding that they might disclose their HIV status to a provider and be told they need to visit their HIV specialist. "If I was someone with cancer and I went to a [PCP] with common cold and I was told, 'Sorry, I can't deal with that' because I've got cancer I'd be so amazed -- that's what our patients our experiencing," Williams said, adding that such practices "den[y]" care to HIV-positive people "at a point where they actually need it." Williams added, "My concern here is that we've still got fear and prejudice and ignorance that's actually driving discrimination and stigma in Wales. And I think this is something major that we have to tackle."
Andrew Dearden, chair of the British Medical Association's Welsh council, said it is "unprofessional and unethical" for physicians to discriminate because of an illness. Dearden added that some physicians might not feel they have adequate training to treat some conditions. "Remember that doctors always refer patients to other doctors ... when they feel there's a need for extra information, diagnosis, tests or treatment," Dearden said. A recent study found that about half of HIV-positive people in the United Kingdom had experience discrimination from a health worker in the previous year, according to a spokesperson from the Terrence Higgins Trust (BBC News, 5/1).
Economic Downturn Likely To Threaten HIV Treatment
According to IRIN/PlusNews, the downturn is likely to have the greatest impact on programs in Southern and Eastern Africa. In addition, many HIV/AIDS programs in this region are heavily reliant on donor funding and have limited support from local governments, IRIN/PlusNews reports.
Joy Phumaphi, World Bank vice-president for human development, said that "[s]ocial services are likely to suffer as governments cut back on spending, currencies devalue and external aid donors come under pressure to maintain existing levels of foreign assistance." Tanzania this year announced plans to reduce its national HIV/AIDS budget by 25%, and similar actions in Kenya and Sudan already have led to medical supply shortages. According to the report, funding reductions might lead countries to reduce emphasis on prevention programs and instead allocate money for treatment initiatives, which produce short-term, easily measurable benefits. According to IRIN/PlusNews, groups such as commercial sex workers, injection drug users and men who have sex with men will likely be the hardest hit by reductions in prevention programs.
Although many countries will face difficult choices during the economic downturn, the report recommends that nations receiving substantial amounts of international assistance use early warning systems to identify any potential drug and funding shortages and avoid treatment interruptions (IRIN/PlusNews, 4/29).

Early HAART Initiation Improves Vaccine Response Among HIV-Positive Children
For the study, Paolo Rossi of the University of Tor Vergata in Rome and colleagues examined 70 children who contracted HIV through mother-to-child transmission and 50 HIV-negative control participants. Of the HIV-positive children, 13 received HAART during their first year, six received no treatment and the remaining children received therapy later in life. All of the children in the study group received the recommended vaccinations for measles and tetanus. According to the study's findings, children who received HAART during their first year maintained normal levels of antibody producing cells, while children in the other groups had lower levels of these cells.
According to Rossi, the timing of HAART initiation is a key factor in determining whether HIV-positive children will develop normal vaccine responses and how long the response will last. The authors write that their findings support early HAART initiation for the purpose of preserving normal immune responses among HIV-positive infants. However, they add that health officials might need to revise vaccine schedules for HIV-positive children who begin treatment after the first year of life (Reuters Health, 4/29).
An abstract of the study is available online.
