Abstract

Background : Chlamydia trachomatis is recognized as one of the most common sexually transmitted pathogen in the world. 50-80% of infected females are asymptomatic. These untreated women are at risk of developing chronic sequelae leading to tubal pathology causing infertility. Infertility is defined as 1 year of unprotected intercourse without pregnancy. It may be primary or secondary. Aim : To find out the association of genital Chlamydia trachomatis infection with female infertility. Materials and Methodology : This case control study has been carried out in collaboration with R. G. Kar Medical College and Institute of Post Graduate Medical Education & Research, India, between July 2012 and June 2013. 40 infertile and 40 pregnant women were enrolled by purposive sampling as per inclusion and exclusion criteria. ELISA test was performed to detect serum IgG and IgA antibody against recombinant analogs of MOMP and 3 different PCR assays were done targeting MOMP and rRNA DNA from DNA extracted from first void urine. Results : IgG seropositivity was significantly higher (15% vs 0%, P=.0255) in cases than controls, though there was no significant difference in the proportion of IgA seropositivity among 2 groups (12.5% vs 2.5%, P=0.2007). Out of 80 samples 2 samples showed the production of amplicons with R1 – R2 primers. Only 1 sample gave positive result with production of amplicons with all the 3 primers used (R1 – R2, CT0005 – CT06 and JM15 – JM16). Conclusion : Persistent C. trachomatis infection must be recognized as a risk factor of infertility in this region of India. The low PCR positivity in FVU sample helps to conclude the diagnostic utility of serological tests in screening of infertile women.
