  • With antibiotic resistance on the rise, scientists are looking for innovative ways to combat bacterial infections. The pathogen that causes conditions from strep throat to flesh-eating disease is among them, but scientists have now found a tool that could help them fight it: a drug approved to treat HIV. Their work, appearing in the journal ACS Chemical Biology, could someday lead to new treatments.

  • [T]here have now been at least three major studies of microbicide gels that have not produced positive results...."To me this study didn't fail," said Sharon Hillier, who moderated a press conference where the FACTS 001 results were presented...."This study answered the question: If you gave women tenofovir gel and told them to use it before and after sex, would it reduce HIV? And the study answered 'No'....The things in clinical trials right now that we are hopeful about are more sustained deliveries."

  • The most exciting news from CROI concerns pre-exposure prophylaxis (PrEP), the use by HIV-negative people of antiretrovirals to prevent HIV infection. Two studies of PrEP in gay men and trans women have demonstrated that the availability of PrEP reduced the rate of infection by 86%. This amounts to the highest effectiveness yet seen for PrEP and is superior to most other HIV prevention interventions.

El-Sadr, AIDS expert at Columbia University and lead investigator. But, she said, there is “promise for using such incentives in a targeted manner”.... Mathematical modeling suggested that paying people up to $5,000 a year could be cost effective, but $280 was settled on after a long, difficult debate....

  • The Centre Medicale de Macenta, a 100-bed medical facility in remote Guinea, managed to provide continuous care during the worst of the epidemic, according to David Leuenberger, MD, of Mission Philafricaine, a Swiss nongovernmental organization. But patients stayed away in droves, he told reporters at CROI 2015. The result was about a 50% drop in HIV testing, new HIV diagnoses, and entry into care, Leuenberger said, although relatively few patients already in care were lost to follow-up.

  • Llamas appear to be immune to AIDS and HIV. The discovery, experts say, just might lead to a vaccine against the deadly virus or a treatment for those already infected. That’s according to new research by experts from University College London, Harvard Medical School and Argentina’s Center of Animal Virology. Their study, published in PLOS Pathogens, says that one llama antibody, which develops in response to the virus, “potently neutralizes more than 95 percent of HIV strains.”

A Toronto Star story earlier this month, which focused on young women who'd suffered serious problems following vaccination, didn't help matters. The paper has since backed away from its story, but some damage may already be done. The Star article was an example of how mainstream media can misreport health-related stories by favoring personal stories over scientific data.

  • We recommend that any cost-effectiveness analysis of the combination HIV prevention (CHP) approach should be extended to allow sex-equity and ethics, as well as other criteria, to be factored into the analysis; likewise, the effect of interventions on the reduction of mother-to-child transmission needs to be considered. To provide direct protection to men, but only indirect protection to women, would be unethical. Furthermore, to preferentially allocate treatment and its survival benefit to men would also be unethical.

  • The cumulative impact of a PrEP intervention could be increased approximately two-fold if positive interactions (between coverage and cost, coverage and adherence, prioritization and time) are assumed, whereas negative interactions between these factors could almost entirely negate the preventive benefit of the PrEP intervention. Model forecasts should reflect that uncertainty and programmes should focus on these factors and measure them.

  • Persons who are HIV infected but undiagnosed and persons HIV diagnosed but not retained in medical care were responsible for 91.5% of the estimated 45 000 HIV transmissions in 2009. Improvements in HIV diagnosis and retention in care, as well as reductions in sexual and drug use risk behavior, primarily for persons undiagnosed and not receiving antiretroviral therapy, would have a substantial effect on HIV transmission in the United States.

  • In this high incidence cohort, daily TDF/FTC conferred impressive protection against HIV, and higher than the levels previously observed in the placebo-controlled trials. Concerns that effectiveness would be undermined in a real-world setting were unfounded. There was no evidence of an increase in STIs in this population, although they were frequently reported in the year before enrolment. This result strongly supports the use of PrEP among MSM who are at risk of HIV infection.
