Treatment News from Recent Conferences: Finding Web Reports

October 26, 2001

Much treatment information came out at several conferences in October and early November. It did not get major press attention because there was no big headline story or single coherent message. Unless you know someone who was there, the best way to learn about these conferences shortly after they happen is through Web reports by researchers, physicians, or other experts. While few will read all this material, patients and medical professionals can scan to find information about problems they are having, treatments they are using, or relevant leads.

You can scan the lists of major topics below to decide what you want to see, then go to the Web sites to read the selected summaries. Note that these reports are written mainly for medical professionals, and some are more difficult than others.

These conference Web reports provide quick, accessible treatment education updates in areas you choose. This article lists major topics reported (as of mid-November 2001, when we went to press).


Recent Conferences

And for reports on liver diseases,


Web Sites with Conference Coverage

The following four sites have extensive reporting on these conferences (though only The Body covered all five of them).

Note the more specific Web addresses for some of the conference coverage, further below. But if one of these addresses does not work (perhaps because the site has been reorganized), use the address here to get to the home page, and then look for the conference coverage on the site. Some sites take down their conference reports after one year.

  • The Body, www.thebody.com, has the most extensive conference coverage.

  • HIV and Hepatitis.com, www.hivandhepatitis.com, has perhaps the most extensive coverage of AIDS and hepatitis treatment news on the Web.

  • Medscape, www.medscape.com, has many excellent medical resources. (You need to register and choose a password to use this site, but the registration is free.)

  • NATAP (National AIDS Treatment Advocacy Project), www.natap.org, has valuable information, though some of it has been technical and hard to read.

While these Web sites are credible, nothing is perfect. These rapid Web reports, often online within days of a meeting, sometimes within a day, do not always leave time for thorough fact checking. And the pervasive "spin" throughout the entire U.S. medical field, especially pharmaceuticals, makes all treatment reporting difficult. The trials conducted and results published reflect complex, often secret negotiations between corporate, professional, regulatory, organizational, personal and other interests. There is no way to cover a field as complex as AIDS and even be aware of all of the important spin.


Approved HIV Drug Names

We use generic drug names in this article -- or the more familiar abbreviations AZT (generic name zidovudine), ddI (didanosine), d4T (stavudine), and 3TC (lamivudine). Generic names are usually but not always used on the sites. For those more familiar with the brand name, here is a table of the brand names and generic names of the anti-HIV drugs currently approved in the U.S. Since all antiretrovirals are patented in this country, there is only one brand name here for each generic (except for saquinavir, which has an earlier, weaker formulation named Invirase).


Ageneraseamprenavir
Combivir[AZT+3TC]
Crixivanindinavir
Epivirlamivudine (3TC)
Fortovasesaquinavir
Hividzalcitabine (ddC)
Kaletralopinavir/ritonavir
Norvirritonavir
Rescriptordelavirdine
Retrovirzidovudine (AZT)
Sustivaefavirenz
Trizivir[abacavir+AZT+3TC]
Videxdidanosine (ddI)
Viraceptnelfinavir
Viramunenevirapine
Vireadtenofovir DF
Zeritstavudine (d4T)
Ziagenabacavir


Major Topics Covered

Here are some of the most important topics on each site, as of November 14. New reports may still be added. If we have missed other sites that should be included, please let us know.

Also note that the same research is often presented at more than one conference. So the same Web site can have different writeups on the same research.

We wrote the title lines below to give a less technical view of the contents of each summary. You can usually spot the corresponding writeup by following the link provided to reach a table of contents for that conference Web report. Many of the summaries are short, a page or less; a few are considerably longer.
