The significance of chlamydia serum IgG and IgA antibodies was studied, by immunoperoxidase assay, in 210 homosexual men at various stages of HIV infection. Cross sectional analysis of chlamydia IgG antibodies at a titer of ≥ 128 indicated a significantly higher prevalence rate among AIDS patients (27.0%) as compared to asymptomatic HIV seronegatives (6.0%) (p = 0.022). The geometric mean titer (GMT) of IgG antibodies to chlamydia was also significantly higher in AIDS patients (106.4) as compared to HIV seronegatives (58.2) (p = 0.022) and persistently asymptomatic HIV seropositives (51.7) (p = 0.05). Chlamydia IgA antibodies did not differ significantly in prevalence and GMT among the various groups.
