RESUMO
To define the impact of human immunolodeficiency virus (HIV) infection in Africa; clinical and laboratory investigations were conducted on 265 HIV-seropositive outpatients in Zimbabwe. Twenty-four of the study subjects were asymptomatic (ASX); 124 had persistent generalized lympademopathy (PGL); and 117 had AIDS-related complex (ARC). HIV infection was assessed by commercial ELISA; Western blots; synthetic peptide ELISA; and measurement of p24 antigen. Serum immunoglobulins; lympocyte mitogen responses; and CD4+ cell numbers were obrtained in 54 sequential patients. Compared to seronegative subjects meab CD4+ cell numbers were decreased and serum immunoglobulins; particularly IgM and IgG; were increased in all groups of seropositive subjects.
