Salvage Therapy

In a story at the Wall Street Journal website, which is giving 10 free days of access, there is a story about "salvage therapy," which is what doctors resort to when an AIDS patient has become "immune" to all AIDS drugs. (Or, more specifically, when HIV has become immune to all current AIDS drugs.)

Steve Kovacev, a sinewy 52-year-old from Truro, Mass., has run the Boston Marathon and sailed in the Transpacific Yacht Race from Los Angeles to Honolulu. Neither event comes close to his current competition: a race for his life.

Mr. Kovacev has AIDS. He has used all the drugs available to fight HIV, the virus that causes the disease, but now almost all regimens have lost strength, and his virus is on the upswing. His plight places him in an unenviable class: the estimated 40,000 U.S. AIDS patients whose illness isn't responding to treatment. As a last-ditch effort, some of these people -- Mr. Kovacev included -- are turning to a regimen known among AIDS patients and doctors as salvage therapy.

In general, salvage therapy refers to any treatment devised by a doctor to save a patient when all other options have failed. There isn't a single recipe for salvage. Some AIDS physicians return to older drugs to wring out a last drop of efficacy, while others bid for access to experimental agents in a desperate attempt to bring the spiraling virus under control.

Today there are about one million people living with HIV in the U.S., with about 40,000 new infections a year. In 2004, the most recent year for which statistics are available, 15,798 people died from AIDS, down sharply, thanks to new AIDS drugs, from 51,000 in 1995. Hepatitis and drug toxicity contribute to deaths among HIV patients. Because of salvage therapy, most patients with drug-resistant virus are, for now, hanging on.

Even with optimal treatment, Daniel Kuritzkes, associate professor of medicine at Harvard Medical School, says, "we've only changed the slope of the disease progression, not halted it altogether, and eventually they do run out of options."



It's that last paragraph that I hate. Eventually, he says, everyone will run out of options, and the virus, so vicious in its ability to mutate, will become immune to all the meds. That's why I get monitored so often. Blood tests every month. Mountains of pills taken on a very strict timing regimen.

The article goes on to state that much of the problem of why the drugs fail is that many patients swap to new drugs as soon as new ones hit the market. So, the virus evolves until there are no more options. I've not changed drugs much. I'm still on one, 3TC, that I've been on almost from the very beginning. So, my practice is to stay on what works until it stops working.

And, so far, so good.

For my birthday, also St. Francis of Assisi Day,

here is "Rescue" the song I sang to Erika Amato 's Buddy the dog. Imagine if we loved humans as much as we love our animals...
