Abstract
Immunologic and conventional laboratory studies were done in 135 previously untreated subjects including 28 (20.7%) symptom-free homosexuals and 74 (54.8%) with ARC and 33 (24.5%) with AIDS. More than half of all patients had abnormal percentages of lymphocytes, percentages of T3+ cells, percentage and absolute number of T4+ cells, percentage of T8+ cells, T4/T8 ratio, monocyte adherence, and serum thymosin alpha 1. Most immune variables worsened with progressive disease. Low lymphocyte 5'nucleotidase increased suppressor cell activity, and impaired IL-2 and alpha interferon production and response suggest diminished mature and increased immature peripheral blood and tissue T cells. These findings suggest approaches to staging, prognostication, and treatment for AIDS.
