Abstract
This research was undertaken to detect the presence of Chlamydia in Pregnant women and Gynaecologic patients in some Tertiary Health Care Centers in the North-Central Nigeria. Six hundred Blood and endocervical swab samples were collected and analysed by ELISA and PCR Techniques respectively. The six hundred blood blood samples were also screened for HIV infection. A structured questionnaire was used to obtain data on socio-demographic and risk factors of Chlamydia from the study participants. A sero-prevalence of 59.0% was recorded for the Hospitals sampled. The sero-prevalence was higher among the gynaecologic patients (62.0%) than the pregnant women (57.5%). The difference was statistically significant (P = 0.0001). Of the four Health Care Centers chosen for the study, the National Hospital, Abuja had the highest prevalence (84.7%), while the General Hospital, Minna, Niger State had the least (28.7%). The difference was also statistically significant (P<0.0001). The prevalence rate of HIV among the participants in the Study Centers was found to be 17.2%. The National Hospital, Abuja had the highest prevalence rate of 24.6%, followed by the Federal Medical Centre, Makurdi, 16.7%, then Federal Medical Centre Lokoja, 12.0% and finally, General Hospital, Minna, 4.7%. Chlamydia was found to be associated with HIV (p<0.0001). Teenage (P<0.0001, OR= 12.35 CI:3.48-43.73), Secondary School Educational level (P = <0.0001, OR=3.69 CI: 1.57-8.98), unskilled occupation (P= <0.0001, OR=4.22 CI: 2.19-8.12), single marital status (P = 0.0002, OR=4.96 CI: 1.98-12.43) and more than one life time partners (P = 0.02, OR=7.35 CI: 3.55-15.21) were the risk factors associated with chlamydial infection. Chlamydia was found to present asymptomatically more than with symptoms (P= <0.0001). Chlamydia was found to be associated with HIV in the study area and may have resulted in the zone emerging with the highest HIV prevalence in the Country. The chlamydial complications considered in this study (PID, ectopic pregnancy and infertility), were not found to be statistically associated
ix
with Chlamydia. Future studies are required to investigate the genotypes of chlamydia in circulation in the study population and to investigate the role of Chalmydia trachomatis genotypes in disease manifestations.
