New Standard of Care
by John S. James
|
|
Four documents released in the last two weeks have formalized a U.S. standard of care for HIV disease. These guidelines outline treatment approaches which are already in use by leading HIV physicians. Their official publication will greatly support efforts to improve the quality of HIV treatment for thousands of patients elsewhere in the medical system who have quietly been receiving seriously inadequate care.
(1) REPORT OF THE NIH PANEL TO DEFINE PRINCIPLES OF THERAPY OF HIV INFECTION outlines current scientific knowledge about HIV disease, and 11 principles on which treatment should be based. Each of the 11 is discussed in detail. Overall there are 28 pages of text, eight pages of illustrations and tables, over a hundred references, and a list of the names and affiliations of the panelists. Because specific guidelines such as particular drugs are not included, it is believed that this document will not need to be updated very often. The 11 principles are:
This report has 16 pages of text, 18 pages of illustrations and tables, and 34 references.
Tables include:
From the IAS RECOMMENDATIONS: "Therapy is now recommended for all patients with plasma HIV RNA concentrations greater than 5000 to 10,000 copies/ml regardless of CD4+ cell count... Therapy should be considered for all subjects with HIV infection and detectable plasma HIV RNA who request it and are committed to lifelong adherence to the necessary treatment. For patients with low plasma HIV RNA levels and high CD4+ cell counts, therapy might be safely deferred in the short term with reevaluation of plasma HIV RNA level every 3 to 6 months. A small minority of subjects who may be true long-term nonprogressors or slow progressors might be identified with this approach... From the (Federal) GUIDELINES: "In general, any patient with less than 500 CD4+ T cells/mm(3) or greater than 10,000 (bDNA) or 20,000 (RT-PCR) copies of HIV RNA/ml of plasma should be offered therapy. However, the strength of the recommendation for therapy should be based on the readiness of the patient for treatment as well as a consideration of the prognosis for disease-free survival as determined by viral load, CD4+ T cell count (Table IV and Figure 1), and the slope of the CD4+ T cell count decline."[Notes: (1) Figure 1 from the GUIDELINES shows how the risk of disease progression depends on viral load and CD4 cell count. (2) Two viral load tests are now in common use in the U.S.: bDNA and RT-PCR. The tests are different; the values reported by the current PCR test tend to be about twice as high on the average as those reported by the bDNA test currently in use. That is why the GUIDELINES gives two numbers for starting therapy -- greater than 10,000 copies if the bDNA test is being used, and 20,000 if the result is from PCR. Each patient should use one kind of test consistently, to show changes in viral load; the two- fold correction factor is for averages, and would not be reliable for an individual, since the tests may respond differently to different strains of HIV.] Why are there two slightly different treatment standards, instead of one? Much of the reason is historical. The IAS panel started first, and released a draft of its guidelines a year ago, at the XI International Conference on AIDS, July 1996 in Vancouver. But that draft had been delayed for months by a publication embargo, and when it became public it was already widely considered obsolete, because its recommendations for treatment were not aggressive enough in light of new knowledge about HIV disease. The panel continued its work, and produced the current draft, which does reflect the new knowledge. Meanwhile, the U.S. Public Health Service, which often takes the lead on such matters, needed to establish its own guidelines process -- partly in order to develop consensus within the government on what treatment should be reimbursed.
How To Get Copies of These ReportsYou can obtain copies of the three government reports by mail, from the HIV/AIDS Treatment Information Service, 800/448-0440 (the opportunistic infection guidelines need to be ordered separately), or from the CDC National AIDS Clearinghouse, 800/458-5231. In case you need the National AIDS Clearinghouse document numbers, they are D936 (the PRINCIPLES, and the GUIDELINES, in one package), and D938 (the final opportunistic infection guidelines, which are published by the CDC in its weekly journal, the MMWR, June 27, 1997).Note that the PRINCIPLES, and the antiretroviral GUIDELINES, are currently drafts, which will be superseded when the final versions are published in MMWR, probably later this year. The IAS RECOMMENDATIONS were published in JAMA on July 1, 1997, and could be found in a medical library. If you have access to the World Wide Web, you can get all four documents immediately. The PRINCIPLES and the antiretroviral GUIDELINES were announced in the FEDERAL REGISTER on June 19, and at that time they were released on the Web site of the National AIDS Clearinghouse, http://www.cdcnac.org, and also on the Web site of the HIV/AIDS Treatment Information Service, http://www.hivatis.org. On these sites the documents are published as "PDF" files to be read by the Adobe Acrobat(TM) reader -- a program which can be downloaded free for all common computers. Some Web browsers can open PDF files automatically. [Note: Some people have had difficulty using the PDF files, because of unfamiliarity with the computer procedures involved. To make these reports more conveniently available online, they have been converted unofficially so that they can be read directly on the World Wide Web; these versions are posted at the site of Healthcare Communications Group, http://www.healthcg.com. Here they can be read like anything else on the Web, with no need to download the PDF files or the Acrobat reader.] The opportunistic infection guidelines can be found at http://www.cdc.gov/epo/mmwr/mmwr_rr.html; this site has current and back issues of the MMWR, in the PDF format. The opportunistic infection guidelines are in the June 27, 1997 issue (volume 46, number RR-12). The IAS guidelines are currently online at the JAMA HIV/AIDS Information Center, http://www.ama-assn.org/special/hiv/library/j97list.htm.
Public Comment PeriodTwo of the Federal documents (PRINCIPLES, and antiretroviral GUIDELINES) were released in draft form for a 30-day public comment period. Written comments must be postmarked by July 21, and mailed to: The HIV/AIDS Treatment Information Service, P.O. Box 6363, Rockville, MD 20849-6303.
Illustration -- Likelihood of AIDSIn our print edition we reproduced a graph, "Likelihood of Developing AIDS Within 3 Years," which is Figure 1 in the antiretroviral GUIDELINES. This illustration would make an excellent poster or postcard to show the importance of getting medical care for HIV infection. It can be found through http://www.healthcg.com (we have not published the direct link, because the site is now being reorganized, and the link will change).

Major Pediatric Study
by John S. James
|
|
On June 26 the U.S. National Institute of Allergy and Infectious Diseases (NIAID) announced that it was stopping a clinical trial in over 600 children ahead of schedule, because those assigned to treatment with AZT plus 3TC did much better than those treated with ddI monotherapy. In this trial, known as ACTG 300, the risk of disease progression was reduced by about 70%, and the risk of death was reduced by about 80%, for those receiving the combination vs. those receiving the single drug. This result is mainly from children under 3 (who were analyzed separately), because there were far fewer cases of disease progression, and no deaths, in the children over 3, so reliable conclusions for them could not be drawn from this study. The children in ACTG 300 had symptomatic HIV disease, and little or no prior experience with antiretrovirals. Both treatment regimens were generally well tolerated.

Saquinavir:
By John S. James
|
|
The largest trial ever conducted in AIDS, enrolling over 3400 volunteers with little or no prior HIV treatment, found that the three drug treatment saquinavir (Invirase(R)) plus AZT plus ddC reduced disease progression or death by 50%, compared to AZT plus ddC, a result which was highly statistically significant (p=0.0001). Deaths alone were reduced by about 42 percent, but due to the smaller number of deaths, this result was not quite statistically significant (p=0.067). The trial, NV 14604, was conducted outside the United States by Hoffmann-La Roche, and reported to the investigators in a two-page executive summary; a more complete report is being prepared for publication.

HIV Resistance International Meeting:
|
|
The important International Workshop on HIV Drug Resistance, Treatment Strategies, and Eradication was held in St. Petersburg, Florida, June 25-28. This highly technical meeting was limited mostly to researchers working in the field; information will be made available to the larger community through various media. We know of two rapid reports:

National Summit Meeting on HIV Resistance, July 17 -- By Telephone |
|
The AIDS Treatment Data Network and Project Inform will sponsor a meeting on HIV drug resistance, Thursday July 17, 8:30 a.m. to 4:30 p.m. Eastern time. It will focus on "protease inhibitor resistance and cross resistance; how current data on resistance affects guidelines for treating HIV; and what health educators need to know and communicate to their clients." Speakers will include leading HIV physicians, treatment activists, and researchers from pharmaceutical companies. This meeting will focus more on community education than on a reportback from the recent resistance meeting in St. Petersburg, Florida.

AmFAR Will End Support of CBCT Network, Begin New Clinical Programby John S. James |
|
The American Foundation for AIDS Research (AmFAR) will end support of its Community Based Clinical Trials network at the end of the current three-year contract cycle in January 1998, except for funding to finish, analyze, and publish the trials still underway. AmFAR will begin a new clinical research program in which it will sponsor studies, but not be involved in their day-to-day management. "AmFAR felt strongly that at this point in the epidemic, it needed flexibility to put out requests for proposals for very specific areas. Continuing to study drugs for their effectiveness -- the kinds of trials being done by government networks and by pharmaceutical companies -- is very expensive and beyond the Foundation's capabilities."AmFAR has spent $30 million on CBCT trials since it started that network in 1989. Some of the 12 sites currently being funded also have other support from government or industry; others do not. AmFAR plans to start the new clinical research program with an RFP (request for proposals) issued in January 1998 for funding in July, and to issue new RFPs annually. This funding will be open to all qualified research groups, not only community-based groups. The kinds of studies which this program will fund "will be determined by outside advisory committees based on urgent research priorities in the epidemic."Grants will be investigator initiated and peer reviewed, and may be in the range of $150,000 to $200,000 for 12 months, renewable; they could be used to fund small, single-site proof of concept trials. According to Dr. Ammann, the total AmFAR funding for clinical research under the new program is expected to be comparable to what is being spent currently. In addition, AmFAR plans grants to community-based organizations, starting in January 1998, "for outreach and education activities...to enhance the recruitment and retention of individuals into clinical trials available in their communities."This program will focus particularly on outreach to disadvantaged groups currently underrepresented in clinical trials.
CommentThe AIDS community, including donors and treatment activist organizations, needs to pay attention to the development of the annual RFPs, and to the composition of the committees involved in selecting which clinical research will be funded.A critical role for medical research supported by public donations is to enable studies which are scientifically sound and can improve medical care, but are not done elsewhere because of lack of financial incentive, or institutional, cultural, or personal biases. This difficult mission requires both expertise and vision. It is easy to miss the mark.

Internet Free Speech Upheldby John S. James |
|
On June 26 the U.S. Supreme Court ruled unconstitutional the key provisions of the "Communications Decency Act" (CDA), which would have made it a felony to place "indecent" material on a computer if a minor could obtain it. The ruling means that the Internet now has the same First Amendment free-speech protections as newspapers and books. The vote was 7-2, but even the minority would have overturned the CDA in most respects. "The Internet is going to be every bit as important as the telephone. The sweeping restrictions of the Communications Decency Act would have knocked the cornerstone out of the First Amendment guarantees of free speech as applied to the Internet for the next hundred years. We, as providers of information on AIDS treatment, safer sex, and risk management for a variety of sexual practices, can breathe a bit easier now. To criminalize the publishing of life-saving but sexually explicit information on the Internet would have been a great public-health mistake."Another litigant against the censorship law, Sister Mary Elizabeth of AEGIS (AIDS Education Global Information System (http://www.aegis.com; for information on AEGIS, see AIDS Treatment News #271), said she was "The Internet is going to be every bit as important as the telephone. The sweeping restrictions of the Communications Decency Act would have knocked the cornerstone out of the First Amendment guarantees of free speech as applied to the Internet for the next hundred years. We, as providers of information on AIDS treatment, safer sex, and risk management for a variety of sexual practices, can breathe a bit easier now. To criminalize the publishing of life-saving but sexually explicit information on the Internet would have been a great public-health mistake. Elated the Supreme Court struck it down. It was too broad and undefinable. If the CDA had been upheld, we would have had to go through every file on our system; up to half might have had to come off [AEGIS has over 350,000 documents online]. You cannot talk about AIDS in an intelligent manner without bringing sex into it. We and others could not have afforded the legal costs, and would have been facing $250,000 fines and imprisonment."For more information on the recent Supreme Court decision, see THE NEW YORK TIMES, June 27, page 1.
