Promising COVID-19 Vaccine Results and Progress on HIV Prevention — All in One Great Day

Monday, November 9, in the bedeviled year 2020, was an astounding day for research on prevention of infectious diseases — really unprecedented. First — we awoke to hear that the Pfizer-BioNTech experimental COVID-19 vaccine was “90% effective” in preventing the disease after the second (of two) doses. This was a planned interim analysis, taking place after 94 […]

A Major Advance in Non-COVID-19 ID Research You Might Have Missed

One thing about the COVID-19 pandemic — other important non-COVID ID news gets crowded out. As a prime example, take HPTN 083, a major clinical trial in HIV prevention. The results are a big deal, and should have garnered more attention when they were released last week. This randomized, double-blind pre-exposure prophylaxis (PrEP) study compared long-acting injectable […]

Is Self-Administered Postexposure Prophylaxis Another Viable Option for HIV Prevention?

Most of the pivotal trials of pre-exposure prophylaxis (PrEP) have used daily therapy. The lone exception is the IPERGAY study. Men at high risk for acquiring HIV took two tablets of tenofovir DF/emtricitabine (TDF/FTC, Truvada) before sex, and one tablet the next 2 days. The strategy was highly effective in preventing HIV acquisition, and intermittent PrEP is endorsed […]

Can’t HIV Serodiscordant Couples Now Just Have Children the Regular Way?

MMWR just published a paper entitled, Strategies for Preventing HIV Infection Among HIV-Uninfected Women Attempting Conception with HIV-Infected Men — United States, and it’s both a welcome and a very strange document indeed. It’s welcome because it acknowledges that serodiscordant couples may wish to have children without the use of an HIV-negative sperm donor. Advances in HIV prevention […]

Case Report of PrEP Failure: What Can We Learn From It?

The New England Journal of Medicine has published the first well-documented case of HIV pre-exposure prophylaxis (PrEP) failure despite good medication adherence. We heard lots of this information at CROI last year, and again I’m impressed at the extraordinary degree of virologic investigation done on a case from clinical practice. To refresh your memory, here are the critical details from the […]

Top Stories in HIV Medicine for 2016

A lot of these “Best of …” or “Top Stories in …” lists have already been published, as they seem to be appearing earlier and earlier each year. Pretty soon we’ll start reading them around the same time they sell Halloween Candy — and that’s just too early, sorry. Now this list, however, appears just as 2016 is in […]

Quick Question: Should HIV-Negative People in Serodiscordant Relationships All Get PrEP?

From a very thoughtful and experienced primary care provider came this query: Hey Paul, quick question — One of my patients, an HIV-negative gay man, is in a long-term relationship with one of your HIV-positive patients — my patient says his partner has been on successful HIV treatment for years. Obviously I can’t check his partner’s […]

2014 Top Stories in HIV Medicine

Boy do we love end-of-year “Best of …” and “Top Stories of …” lists! Love them! They never gets old! Until January, that is. My own particular favorites are the Best Movies of the Year lists, since for whatever reason it always seems like some masterpiece slips by. Missed it! So we leave it up to the […]

Holiday Season 2014 ID/HIV Link-O-Rama

A little spin around the internet brings us these ID/HIV tidbits, all of them designed to go well with holiday music, egg nog, and potato pancakes, plus a can’t-miss video clip: Flu vaccine match with circulating virus doesn’t look so great. This could mean it’s going to be a tough flu season, but estimates of flu […]

Why the IPERGAY (Yes, That’s Its Name) Study Could Substantially Increase Use of PrEP

Yesterday, the French IPERGAY study of intermittent pre-exposure prophylaxis (PrEP) was stopped early by the Data Safety Monitoring Board, and for the best reason — the evidence demonstrating that it prevented HIV was overwhelming. For those who read French, here’s the official announcement. (Scroll down for the English.) And for those who can’t believe the name, it stands […]
