Perinatal Transmission of HIV “Solved” — Now How Do We Pay For It?

Conspicuously absent from this year’s International AIDS Conference were major studies on prevention of maternal-to-child transmission. It could be that I just missed them, so I emailed a colleague who specializes in the area, and she concurred: Nope, did not see or hear major PMTCT updates at IAS. The thing is, this problem has been all but solved, […]

Vienna IAS: First (Really) Positive Microbicide Study

Big news from Vienna and Science, imminently: The CAPRISA 004 trial assessed effectiveness and safety of a 1% vaginal gel formulation of tenofovir, a nucleotide reverse transcriptase inhibitor, for the prevention of HIV acquisition in women. A double-blind, randomized controlled trial was conducted comparing tenofovir gel (n = 445) with placebo gel (n = 444) in sexually active, HIV-uninfected 18- to 40-year-old women in […]

Neutralizing AB and How to Interpret HIV Vaccine News

Lots of attention in the news media on the recent papers in Science that elucidate the structure and function of broadly neutralizing antibody to HIV.  (Proof:  a patient asked me about it today.) For example, here’s the take by the Wall Street Journal: HIV research is undergoing a renaissance that could lead to new ways to develop […]

Torrid Tuesday

Some ID/HIV-related items for a sweltering summer day: Are the AIDS Drug Assistance Programs (ADAPs) in trouble?  Certainly in some states they are, and this interview gives additional perspective.  But I wonder — how much of this is HIV-specific, and how much is just the ongoing lousy economy.  In other words, are other government-funded programs comparably stressed?  Headline:  […]

RFA-AI-10-009, HIV Cure, and “Berlin Patient” Update

Interesting “RFA” (Request for Application, #RFA-AI-10-009) from Bethesda: The National Institute of Allergy and Infectious Diseases (NIAID) and the National Institute of Mental Health (NIMH), National Institutes of Health (NIH), encourage grant applications from institutions/organizations to address the problem of HIV-1 persistence in HIV-1-infected persons treated with suppressive antiretroviral drug regimens… The goal of this initiative […]

Combined HIV Antibody/Antigen Test Approved

From the FDA: The U.S. Food and Drug Administration today approved the first assay to detect both antigen and antibodies to Human Immunodeficiency Virus (HIV)… The highly sensitive assay is intended to be used as an aid in the diagnosis of HIV-1/HIV-2 infection, including acute or primary HIV-1 infection. Since it actually detects the HIV-1 […]

Another HIV Drug Development Program Bows Out

Last month, Avexa announced that they will not be going forward with their development of the investigational NRTI apricitabine. Now Myriad says its program to develop bevirimat is closing as well. The problems with these drugs — twice daily dosing with apricitabine, formulation and mixed responses with bevirimat — are not the real story here, since arguably we […]

Plays at the (Culture) Plate

Some quick ID/HIV/other thoughts while we marvel in all that is Strasburgian: Did you know that HIV medication adherence improves over time? So much for “pill fatigue.” By the way, this anecdotally fits with my experience as well. And right now, the biggest reason for patients’ stopping their HIV meds is financial, usually due to loss of or […]

Screening for Anal Cancer and the World’s Worst Job

In Journal Watch AIDS Clinical Care, we published a simple case:  Clinically stable HIV+ gay man, on HIV treatment; anal pap comes back with “atypical squamous cells of undetermined significance” (ASCUS). What to do with this result?  Two experts weighed in, Howard Libman and Joel Gallant.  In Howard’s thoughtful response, he acknowledges the limitations of the data thus […]

HIV Treatment is Prevention!

The Lancet has just published a large prospective study demonstrating the protective effect of HIV treatment on the risk of viral transmission: 3381 couples were eligible for analysis … Only one of 103 genetically-linked HIV-1 transmissions was from an infected participant who had started ART, corresponding to transmission rates of 0·37 (95% CI 0·09—2·04) per 100 person-years […]
