Prevalence of antibodies against Chlamydia trachomatis and Neisseria gonorrhoeae in Mexican populations [Prevalencia de anticuerpos anti-Chlamydia trachomatis y anti-Niesseria gonorrhoeae en grupos de individuos de la población mexicana]
Objective. To estimate the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infection in groups of individuals at different risks of sexually transmitted infections (STI). Material and Methods. Between January 1992 and December 1993, a cross-sectional multicentric study was carried out at the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán (National Institute of Medical Sciences and Nutrition Salvador Zubirán) in Mexico City. The study population consisted of 945 reproductive age subjects (585 females and 360 males). Low and high risk groups were classified according to their risk for STI. High risk groups included infertile women with tubal damage, women with a history of ectopic pregnancy or abortion, infertile men, HIV/ AIDS patients, homo- or bisexual men, and female commercial sex workers. Low risk groups included primigravidae, fertile men, and infertile women with no tubal damage. Serum anti-NG and anti-CT IgG and IgA were determined, in duplicate by immune-enzymatic assay, using as antigens NG pili and the LI fraction of CT. Descriptive analysis is presented as percentages. Results. NG prevalence in females was 13.7%25 by IgG and 14.3%25 by IgA. CT prevalence was 11.4%25 by IgG and 4.4%25 by IgA. In males, NG prevalences were 3.3%25 and 13.3%25 by IgG and IgA, respectively; CT prevalences were 7.2%25 and 5.5%25, respectively. In commercial sex workers, NG prevalences were 31.2%25 by IgG and 28.4%25 by IgA, and CT 25.0%25 and 5.7%25 by IgG and IgA, respectively. In women with infertility due to tubal damage the prevalences of NG were 5.6%25 and 9.8%25, respectively, and those of CT were 8.4%25 and 1.4%25, respectively. In 110 young primigravid NG prevalences were 4.5%25 and 10.0%25, respectively, and CT 3.6%25 and 9.1%25. Conclusions. These data confirm the high prevalence of Neisseria gonorrhoeae and Chlamydia trachomatis in female commercial sex workers and homo- or bisexual men, but not in other high-risk groups like infertile women or women with a history of ectopic pregnancy or abortion.
