We reviewed the records of 85 patients infected with both human immunodeficiency virus and Cryptococcus neoformans. Twenty-seven patients (32%) had pulmonary cryptococcosis. C. neoformans was cultured from bronchoalveolar lavage (BAL) or pleural fluid in 25 cases; the remaining two patients had cryptococcal antigen (CA) detected in BAL fluid and C. neoformans cultured from other sites. All but one of the 27 patients had detectable CA in serum. The CD4+ lymphocyte count was low in all cases (median, 24/mm3). Clinical manifestations of pulmonary cryptococcosis included fever (94%), cough (71%), dyspnea (7%), expectoration (4%), chest pain (2%), and hemoptysis (1%). Diffuse interstitial opacities (70.5%), focal interstitial abnormalities, alveolar opacities, adenopathies, cavitary lesions, and pleural effusions were evident. Outcome was poor (mean survival time, 23 weeks) despite treatment. Patients with localized pulmonary cryptococcosis appeared to have a higher CD4+ lymphocyte count, an earlier diagnosis, lower serum CA titers, fewer previous or concomitant infections, and a better prognosis than patients with disseminated cryptococcosis.

We conducted a descriptive study in 9 cases of acute hepatitis A diagnosed in patients with human immunodeficiency virus (HIV). Despite the small number of cases studied, the results indicate that moderate HIV infection does not impair the natural history of acute hepatitis A.
