Abstract
An immunoperoxidase test detecting Chlamydia trachomatis specific serum IgG and IgA antibodies, was carried out to determine its efficacy in establishing chlamydial etiology in 104 clinically diagnosed patients attending a major STD Clinic in Delhi. The patients consisted of 58 with nonspecific urethritis/cervicitis (NSU/NSC), 11 with pelvic inflammatory disease (PID), 23 with primary infertility in either male or female and 12 with lymphogranuloma venereum (LGV). IgG antibodies were tested at a dilution of 1:64 and 1:128 and IgA antibodies at 1:16. Although 27.7 per cent (5 of 18) of the controls had IgG antibodies (> or = 1:128), none had IgA, showing the IgA marker as 100 per cent specific. In 80.8 per cent of all the patients, active infection was detected, 81.0 per cent in NSU/NSC, 81.8 per cent in PID, 76.9 per cent in female infertility, 80 per cent in male infertility and 83.3 per cent in LGV patients. The immunoperoxidase test was found to be an extremely simple and rapid test especially suited for laboratories where facilities are limited.
