The Food and Drug Administration's (FDA) Antiviral Drugs Advisory Committee met February 27 to March 1, 1996. At the meeting, the FDA granted full approval of ritonavir for the treatment of advanced AIDS. Ritonavir manufacturer, Abbott Laboratories, characterized the drug as generally well-tolerated, with the most common side effects being nausea, vomiting, and diarrhea. The committee also recommended accelerated approval of Merck's protease inhibitor, indinavir. Results of several clinical studies and protocols are presented. The committee voted against somatropin (Serostim), the recombinant human growth hormone, for treatment of AIDS-related wasting syndrome. They cited too many gaps in the research data. The manufacturer, Serono, is currently negotiating with the FDA on the best way to pursue approval. The committee also unanimously recommended that ddI (Videx) be indicated as a first-line treatment for HIV. The drug appears to be superior to AZT in delaying disease progression and death.

Glaxo-Wellcome is developing a nucleoside analogue, 1529U89. The analogue shows potent in vitro activity against HIV, and initial tests of in-vivo efficacy are encouraging. The primary side effects of 1529U89 were nausea, headache, rash, and elevated liver function tests. Since the drug penetrates the central nervous system, participants are asked to allow spinal tips to measure the concentration of the drug in spinal fluid. Trials are being developed for 1529U89's use in AIDS-related dementia, and trials are being designed to test its effectiveness in combination with AZT and 3TC.

3TC can raise T4 counts and lower HIV levels, and its use may increase the effectiveness of AZT. Studies show that HIV levels decrease by more than 90 percent in people taking the 2 drugs in combination. Side effects are manageable, and few participants drop out of the studies. Another study showed that 3TC also lowered the amount of hepatitis B virus in the blood to a level where it could not be detected. Side effects include headache, nausea, fatigue, diarrhea, neuropathy, and lowered levels of both red and white blood cells. HIV cells can mutate and resist the effects of 3TC within a few weeks of beginning treatment. The manufacturer, Glaxo Wellcome, has a patient assistance program and an expanded access program for the drug.

Ritonavir (Norvir), a protease inhibitors, was approved for HIV treatment by the Food and Drug Administration (FDA). Studies have shown that ritonavir helps people live longer and delays the progression of the illness. One study showed that the death rate for the treated group was half that of the group taking a placebo. Ritonavir should be taken with meals. Many people cannot tolerant the side effects, including nausea, vomiting, weakness, diarrhea, elevated liver enzymes, and numbing around the mouth. Ritonavir affects the way other drugs are absorbed by the body, and its use should be closely monitored for toxic reactions.

The National Association of People with AIDS (NAPWA) released a May 2, 1996, report stating that the tap water in the nation's major cities places people with weakened immune systems at risk for contracting cryptosporidium. Cryptosporidium is a potentially life-threatening microscopic parasite. In people with compromised immune systems, the symptoms of diarrhea, headache, abdominal cramps, nausea, vomiting, and fever can persist for months and lead to death. Twenty-two of the thirty-one cities surveyed had no testing or notification policies in place to reduce an outbreak of cryptosporidium. NAPWA recommends that people with HIV disease in extremely high-risk cities (Atlanta; Dallas; Minneapolis; Newark, NJ; St. Petersburg, FL; and Washington, DC) refrain from drinking tap water. Another 22 cities were found to be at high risk for an outbreak.

The Food and Drug Administration (FDA) approved the broad-spectrum antibiotic azithromycin for prevention of Mycobacterium avium complex (MAC) in people with advanced HIV disease. The treatment offers flexibility in that it can be taken once a week. Clinical trials show that 1200 mg of azithromycin taken weekly reduced the risk of developing MAC bacteria in the bloodstream. In a large double-blind study, the drug was more effective than rifabutin in preventing MAC. A combination of azithromycin and rifabutin also was shown to be more effective than rifabutin alone. Common side effects for the drug include diarrhea, nausea, and abdominal pain.

Certain HIV drugs have significant side effects. There have been reports from Europe that some hemophiliacs using protease inhibitors suffered from spontaneous bleeding. Clofazimine, sold as Lamprene, has been shown to cause harm when used with clarithromycin and ethambutol to treat MAC. Lamprene may cause internal bleeding, nausea, diarrhea, dizziness, drowsiness, and dry skin. Results of a Taiwanese trial of thymosin-alpha indicate that it did not help treat Hepatitis B in a statistically significant way. NAC, an antioxidant, may increase glutathione levels and indirectly increase survival.

Many people living with HIV use marijuana to manage agitation, spasms, chronic pain, depression, nausea arising from chemotherapy, and loss of appetite. Concerns over the use of marijuana or dronabinol (a pharmaceutical version of tetrahydrocannabinol or THC) include potential contamination from pesticides or other chemicals used in the growing process, and the potential of increasing the likelihood of lung infections. Use of THC is associated with reduced levels of testosterone and may have similar effects on other hormones in women. THC can also interact with other mood-altering medications such as Valium, librium, Xanax, seconal, Nembutal, or phenobarbital, by exaggerating their effect.

A report is presented of a 48-year-old gay man, HIV-positive for 7 years, who came to the emergency room due to six hours of abdominal pain accompanied by anorexia, nausea, and dry heaves. Initial examination and laboratory tests showed nonspecific bowel gas, and the patient was discharged with instructions to use an enema at home for constipation. After worsening of symptoms, a private physician diagnosed acute abdomen with surgical consultation. A jejunal perforation secondary to B-cell Hodgkin's lymphoma was diagnosed and the patient was treated with low-dose CHOP (cytoxan, adriamycin, vincristine, and prednisone) for four cycles and had his antiretroviral regimen changed.

A 56-year-old, obese woman who had been sexually inactive for 10 years presented at the hospital with high fevers, decreased appetite, nausea, vomiting, and weight loss. Following many diagnostic tests that revealed little, it was found that her estranged husband was being treated for Pneumocystis carinii pneumonia (PCP). The woman was tested for HIV and found to be positive. This is an example of the Centers for Disease Control and Prevention's (CDC) indication that 10 percent of reported AIDS cases occur in people over age 50, that diagnosis is often delayed in older age groups, and that anyone suffering from fever of an unknown origin should be tested for HIV. In such situations it is suggested that general practice include seeking behavioral information and offering HIV testing and counseling.
