New Case Definition for HIV Infection? Yawn …

The CDC has revised its case definition for HIV infection and AIDS, so that now laboratory evidence — a positive antibody test, or detectable HIV RNA or DNA – is required for the diagnosis. It’s not intended to guide clinical practice, but still — what took them so long?  A clinical diagnosis of AIDS was only necessary […]

More Support for HIV Screening

On Monday December 1 — World AIDS Day, if you’re keeping track — the American College of Physicians released a position paper supporting routine HIV screening for adolescents and adults in the United States.  (If you don’t want to read the whole thing, we’ll have a perfectly-executed summary by the inimitable Abbie Zuger on our AIDS Clinical […]

How to End the HIV Epidemic

Answer:  Put everyone on treatment. Conspicuously absent for decades, the prevention part of the “when to start antiviral therapy?” question has now moved front and center in two recent papers:  In this week’s Lancet, a group from the WHO estimated what would happen if there were annual universal HIV testing, and then immediate treatment for all […]

“Salvage” Rx for HIV: Macro Good News, Micro Bad News

I’ve written before how the number of treatment experienced patients who have no options for successful therapy has dwindled to a tiny — but unfortunate — few.  Darunavir, maraviroc, raltegravir, and etravirine (in order of FDA approval) are that good. Two presentations at recent scientific meetings confirmed the staggering efficacy of these newer drugs. Notably, both […]

Promising C diff Rx, and Google as Surveillance Tool

A few items from recent ID/HIV news: Bad enough when it happens once, relapsing C diff is one of the modern plagues for which our bag of tricks sometimes comes up woefully short.  (Anything that tests stool transplants as a therapy is pretty desperate.)  Here was some bright news on the treatment front, however:  an experimental […]

Yes, Just a Case Report, but Incredibly Cool

At this year’s Retrovirus Conference (was it really this year’s conference, seems like much longer ago than that), there was a poster presentation summarizing a very unusual case.  A man with HIV, stable on antiretroviral therapy, developed acute leukemia.  He underwent an allogeneic bone marrow transplant — here’s the kicker — from a donor who […]

The Big HIV News from ICAAC/IDSA

Tons of interesting stuff at this year’s combined ICAAC/IDSA meeting, most of it in non-HIV related Infectious Diseases.  In aggregate, literally hundreds of posters, presentations, and symposia on MRSA, C diff, osteomyelitis, complicated UTIs, hospital-acquired pneumonia, antibiotic resistance … It’s a great meeting to catch up on general ID, and the literature review sessions alone […]

Back to School, Day 4: PEP and More PEP

After a lecture on HIV for Primary Care Providers in our course last week, the most controversial topic was, not surprisingly, the use of post-exposure prophylaxis (PEP) for both occupational and non-occupational exposures.  And today, after an entire lecture on PEP to a group of HIV providers in our AIDS course, again the subject drew […]

Back to School, Day 2

During the course, often the best questions and anecdotes come during the breaks.  Here are a few: Tons of questions about our favorite nemesis, MRSA.  What works for chronic carriers?  How do you manage family members who you suspect would be culture-positive (and the source of recurrences), but are not your patient?  What if the vet […]

The French Win This One

The 2008 Nobel Prize in Medicine goes to Françoise Barré-Sinoussi and Luc Montagnier for discovery of HIV.  They each get one-quarter of the prize money, with one-half going to Harald zur Hausen for showing the relationship between human papillomavirus and cervical cancer. For the record, if you search the Nobel press release for the word “Gallo”, […]
