Histoplasmosis as a cause of pleural effusion in the acquired immunodeficiency syndrome.

Disseminated histoplasmosis is an increasingly important opportunistic infection in patients with the acquired immunodeficiency syndrome (AIDS). We report the first case of histoplasmosis as a cause of pleural effusion in a patient with AIDS. Recognition of the typical intracellular yeast on a Wright-Giemsa stained smear of the pleural fluid cells allowed prompt initiation of amphotericin B.

Asymptomatic glomerulonephritis after nonstreptococcal upper respiratory infections.

Two hundred forty previously healthy military personnel with nonstreptococcal upper respiratory infections were prospectively studied to define the incidence and clinicopathologic characteristics of possible virus-associated glomerulonephritis. Nine patients without preceding streptococcal infection had erythrocyte casts on urinalysis and glomerulonephritis on biopsy. Of these nine, four had a reduction in total hemolytic complement and five had serologic evidence of infection with adenovirus, influenza A, or influenza B. Initial renal biopsy showed either focal or diffuse mesangial proliferation in all nine, with mesangial C3 deposits in six specimens. Repeat biopsy in three showed histologic improvement or loss of immunofluorescent staining, or both. Sequential creatinine clearances were reduced to 74 to 90 mL/min.1.73 m2 in five patients for the duration of follow-up. We conclude that nonstreptococcal upper respiratory infection is frequently associated with glomerulonephritis and that abnormal glomerular structure and decreased creatinine clearances may persist for at least 2 to 8 months.
