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.

In a case-control study, prophylaxis with cotrimoxazole for toxoplasmic encephalitis (TE) in HIV-infected patients was evaluated. Cotrimoxazole had been given as PCP prophylaxis. 20 patients with TE were identified and 72 matching control cases were found. All patients had IgG-antibodies to Toxoplasma gondii and CD4+ T-cell counts < or = 100/microliter. The use and duration of cotrimoxazole prophylaxis were recorded. It was found that among the patients with TE, none had used cotrimoxazole for > 70% of the observation time, and that the 1-y incidence was 0% in the control group vs. 41% in those patients without sufficient cotrimoxazole use. The conclusion is that cotrimoxazole is effective as primary prophylaxis for TE, even in a dose of 480 mg daily.

The U.S. Public Health Service and the Infectious Diseases Society of America recently updated the 1995 guidelines on prevention of opportunistic infections in HIV infected individuals. PCP prophylaxis has not been changed in the new guidelines. Primary prevention strategies for toxoplasmosis encephalitis are described. Preventive medication for tuberculosis is generally not recommended, especially for persons in high risk groups such as the homeless and injection drug users. Significant changes were made for the prevention of Mycobacterium avium complex (MAC), and guidelines were changed for preventing bacterial respiratory infections. Primary prophylaxis of most fungal infections is generally not recommended, but lifelong secondary prophylaxis is indicated for all deep seated fungal infections and CMV. Prevention of opportunistic infections in HIV patients has a significant impact on morbidity and mortality.

We retrospectively reviewed 205 HIV-infected patients, who came at first entry from January 2001 to December 2002 to the Hospital Kuala Lumpur, Kuala Lumpur, Malaysia. The aged range was 21-69 years [mean 37.25 years (+/- SD) 8.1]. Subjects were mainly in the age group 35-44 years. The majority of patients were male (82%), Chinese (55.1%), single (55.6%), resided in Kuala Lumpur (55.1%), and were unemployed (57.1%). The most frequent routes of transmission were sexual contact (78.5%), followed by IDUs (30%), blood transfusion (5%), and unknown (0.5%). Oral candidiasis was the most common mucocutaneous disease and significant co-existence was found with the main opportunistic systemic diseases, such as TB, PCP, toxoplasmic encephalitis, penicillosis, and CMV retinitis (p < 0.05). In this study, the range of CD4 counts was 0-910, with a median of 35 cells/mm3. Significant associations between a CD4 level less than 100 cells/mm3 at the time of diagnosis, and the occurrence of major opportunistic diseases, such as candidiasis, TB, PCP, TE, herpes simplex infection, CMV retinitis, penicillosis, and histoplasmosis were found (p < 0.05) in this study.
