Abstract

The authors report two cases of acute myocarditis due to Staphylococcus aureus in patients with AIDS. There was no history of opportunist infections in either case but the CD4 lymphocyte levels were very low. The myocarditis caused acute cardiac failure and death. Histological examination showed microabscesses filled with Gram positive cocci throughout the myocardium. Bacteriological studies identified the Staphylococcus aureus. Staphylococcus aureus myocarditis without endocardial or pericardial involvement is very rare. It is the result of septic emboli in the cardiac microcirculation. Bacterial myocarditis has rarely been diagnosed in HIV positive patients. Both our cases featured severe cell-mediated immunodeficiency without associated neutropaenia. The decreased bactericidal activity of the neutrophil polynuclears and/or a deficit in the immunity mediated by the B-cell lymphocytes in AIDS could explain the lethal septic complications observed in our two cases.

Polymorphous hemangioendothelioma in a child with acquired immunodeficiency syndrome (AIDS).

Polymorphous hemangioendotheliomas (PH) are rare and borderline malignant tumors that are among the wide range of vascular tumors. We report here a 13-year-old male presenting with a history of weight loss, opportunistic infections, and lymphadenopathy. He was determined to be HIV positive and to have acquired immunodeficiency syndrome (AIDS). A biopsy of a femoral node was diagnostic of PH. His systemic lymphadenopathy appeared to resolve with anti-retroviral therapy. This tumor should be considered within the differential diagnoses of pediatric and immunocompromised patients.

Brief report: effectiveness of combination antiretroviral therapy on survival and opportunistic infections in a developing world setting: an observational cohort study.

BACKGROUND: The prolonged effectiveness of antiretroviral therapy (ART) in a developing country is not well established. METHODS: An observational database was established at the HIV clinic of the Almenara Hospital in Lima, Peru in 1996. All 564 initially antiretroviral-naive HIV-infected persons (mean CD4 count of 91 cells/mm3) who received combination ART were followed over time. RESULTS: The overall survival rate was 96% at year 2, 94% at year 4, and 91% at year 5. Among persons who initiated therapy with CD4 counts <100 cells/mm3, the overall survival rate at 3 years was 95%. Opportunistic infections while on ART occurred in 20% of persons. Patients who received 2 reverse transcriptase (RT) inhibitors plus a protease inhibitor had slightly better survival rates and less opportunistic disease in the first year of therapy as compared with those receiving 2 RT inhibitors and a nonnucleoside reverse transcriptase inhibitor or 3 RT inhibitors. CONCLUSIONS: This study demonstrates the long-term effectiveness of ART in a developing country urban setting. It provides evidence of the importance of continuing global financing initiatives to provide widespread HIV therapy for countries in the developing world.

Gender differences in AIDS-associated Kaposi sarcoma in Harare, Zimbabwe.

Reasons for gender-related differences in the risk of AIDS-related Kaposi sarcoma (AIDS-KS) are unknown. Four hundred thirty-eight male and 166 female AIDS-KS patients were evaluated in Harare, Zimbabwe. Female patients were younger than male patients in this study (median of 33 vs. 38 years; P < 0.001), mirroring the epidemiology of AIDS in Zimbabwe. In a multivariate model adjusted for CD4 T-cell count, age, prior radiation treatment, and chemotherapy, women were more likely to report fever, diaphoresis, or weight loss (odds ratio = 1.7, 95% confidence interval: 1.1 to 2.7; P = 0.009). These findings suggest an increased severity of KS or other unidentified infections among women with AIDS-KS in Zimbabwe.
