Serum total testosterone, total 17 beta-estradiol, LH, FSH, and PRL concentrations were measured by RIA in 59 homosexual men infected with the human immunodeficiency virus (32 clinically healthy antibody-positive men (HH+), 20 men with acquired immune deficiency syndrome (AIDS), and 7 men with AIDS-related complex (ARC). The results were compared with those of 26 antibody-negative homosexual men (HH-) who served as controls. The mean serum total testosterone concentration was significantly lower in the men with AIDS [414 +/- 230 (+/- SD) ng/dL (14.5 +/- 8.0)] than in the HH- men [550 +/- 172 ng/dL (19.0 +/- 6.0 nmol/L); P less than 0.05]. The mean serum LH level was significantly higher in the men with AIDS (26 +/- 14 vs. 14 +/- 4 IU/L in HH- men; P less than 0.01) and slightly but significantly higher in the men with ARC (19 +/- 8 IU/L; 0.10 greater than P greater than 0.05). Serum FSH also was significantly higher in the men with AIDS (P less than 0.05). Serum PRL was significantly higher in the men with ARC (10 +/- 2 micrograms/L; P less than 0.05) and AIDS (16 +/- 10 micrograms/L; P less than 0.001) than in the HH- men (8 +/- 3 micrograms/L). Serum sex hormone-binding globulin levels were similar in HH- men and men with AIDS as were serum T responses to hCG administration for 2 days. These results suggest that alterations of the hypothalamic-pituitary-gonadal axis indicative of primary hypogonadism accompany human immunodeficiency virus infection in homosexual men.

During one year, 55 bone marrow biopsies from 49 patients with CDC-defined acquired immune deficiency syndrome (AIDS) were studied. Eighty-three percent were normocellular or hypercellular; 17% were hypocellular. Marrow plasma cells were increased in 83% of patients, most showing polyclonal hypergammaglobulinemia. Forty percent of patients showed peripheral neutropenia, 29% thrombocytopenia, and 79% lymphopenia with markedly reduced T4+ lymphocytes. Eighty-five percent of patients were anemic, with iron studies showing a pattern consistent with the anemia of chronic disease. Mycobacterium avium-intracellulare (MAI) grew from ten (20%) biopsies, four with granuloma and six without granuloma (five of these six also showed marrow hypocellularity). Small poorly formed granuloma (70-150 micron) were seen in eight (16%) patients (four AFB-culture positive, 4 negative). Three of four granuloma-positive, culture-negative cases eventually grew MAI from autopsy material. Five (10%) patients had lymphoplasmacytic aggregates; later, one developed lymphoma, another, markedly atypical lymphoid hyperplasia. Two additional patients showed marrow B-cell lymphomas. Of these findings, only marrow MAI meets the CDC definition of AIDS. However, in this series, small ill-defined granulomas, lymphoplasmacytic aggregates, and B-cell lymphomas also were found. The authors conclude that these latter findings, when seen in high-risk patients, particularly those with lymphopenia, anemia, and/or hypergammaglobulinemia, also strongly suggest the diagnosis of AIDS.

We studied unselected, hepatitis B surface antigen (HBsAg)-positive parenteral drug abusers for antibody to hepatitis D virus (anti-HD) and antibody to human immunodeficiency virus (HIV). The prevalences of anti-HD and antibody to HIV were 67% and 58%, respectively, and there was no association between positivity for these two markers. In a logistic regression model, anti-HD was associated with older age (P = .001), longer duration of drug abuse (P = .045), and the presence of liver disease (P = .002). Antibody to HIV was associated with a younger age (P = .003) and increased serum globulin levels (P less than .001). In patients infected with HIV, the severity of hepatic dysfunction remained correlated with anti-HD. In anti-HD-positive patients, most indices of hepatic dysfunction were similar whether or not antibody to HIV was present, but serum aspartate aminotransferase levels were significantly higher in patients with both anti-HD and antibody to HIV. (124 +/- 16 vs. 74 +/- 11, P less than .05).
