Four hundred and eighty six infected adults (90.7% men) were prospectively followed from 1988 to 1993 at a multiprofessional center in Santiago, Chile. 87.8% of male patients (pts)--84% of them homo/bisexual--and 64.4% of women acquired the infection sexually. At the beginning of the follow up (F/U) 51% of men and 71% of women were asymptomatic and 30% of the total group had AIDS. (AIDS definition: CDC 1993, excluded CD4 lymphocyte count < 200 x mm3). 240/486 (49.4%) had developed AIDS at the end of the study (12/31/93). AIDS defining events (ADE) were: interstitial pneumonia (confirmed or suggestive as caused by P. carinii [PCP]), 25%; tuberculosis (all forms), 22.1%; wasting, 13.8%; Kaposi Sarcoma, 9.2%; esophageal candidiasis, 6.7%; isosporiasis, 5.4%. Of all PCP cases, 72% were ADE, the rest, post.AIDS'. As expected, AIDS pts continued having major complications (mainly bacterial pneumonias, PCPs, esophagitis, tuberculosis and diarrhea due to I. belli and Cryptosporidium. Less frequently, but also observed, were toxoplasmic encephalitis and cryptococcal meningitis). Known mortality (excluded abandonment of F/U) was 27% for the whole group and varied from 5.8%, 51.6% to 69.2% for the first, 4th and 6th year of F/U respectively. For II-III CDC pts the mortality was 5% and 57% and for IV CDC pts it was 38% and 100% during the first and 6th year of F/U respectively. 36%, 53%, 74% and 85% of the pts followed for 1, 3, 5 and 6 years respectively had developed AIDS by the end of 1993. Multifactorial causes with either diarrhea, wasting or both were responsible for the death in half the pts in whom this was known, 15% died of respiratory complications and 5.7% of cryptococcal meningitis. 80% of AIDS pts survived their ADE. This study has provided information about the clinical profile of the HIV infection and natural history of the disease in Chile.

Clinicians have had some success in treating or preventing several rarely discussed opportunistic infections. The author discusses seven infections, outlining the disease and possible treatments. Aspergillosis, a fungal infection found in the lungs and sinuses, can be treated with intravenous amphotericin B. However, researchers are studying oral itraconazole as an alternative treatment. B-19 parvovirus is a viral infection that may cause severe anemia, a decrease in red blood cell count or hemoglobin. A small study suggests that IVIG (intravenous immune globulin) was effective in reversing B-19 parvovirus-related anemia in seven HIV-positive patients. Coccidioidomycosis, an uncommon fungal infection usually seen in the lungs, has symptoms closely resembling those of PCP. Treatments include amphotericin B, or ketoconazole or fluconazole for mild cases. Histoplasmosis usually occurs in AIDS patients with fewer than 100 CD4 cells. A fungal infection, histoplasmosis can be treated with amphotericin V and itraconazole. Isosporiasis invades the intestines, causing persistent, watery diarrhea and other symptoms resembling cryptosporidiosis. Sulfadoxine and pyrimethamine combined can prevent the return of the organism. Molluscum contagiosum is a viral infection that produces small, white wart-like bumps on the skin. Bumps can be removed with an electrical charge or with liquid nitrogen. Progressive multifocal leukoencephalopathy (PML) is a life-threatening brain disorder. A very small study suggests that patients who received cytosine arabinoside (ara-C, cytarabine) stabilized and improved after treatment.
