relationship between Chlamydia trachomatis genital infection and spontaneous abortion

Background: Chlamydia trachomatis is the etiology of most of sexually transmitted diseases. Colonization of C. trachomatis in the genital tract during early gestation has been associated with preterm birth, and preterm premature rupture of the membranes. The role of C. trachomatis on spontaneous abortion has not yet been proved completely. The aim of this study was to evaluate the frequency of C. trachomatis infection among pregnant women and its association with spontaneous abortion

Methods: This case-control study was conducted from August 2012 until January 2013. Totally, 218 women were included; 109 women with spontaneous abortion with gestation age between 10-20 weeks [cases], and 109 women with normal pregnancy with gestation age between 20-30 weeks [controls] in Sanandaj, Iran. DNA was extracted from endocervical swabs and a PCR test was conducted for detection of C. trachomatis infection in women using specific primers. Independent T-test and Chi-square were used for comparison of quantitative and qualitative variables, respectively, and p<0.05 was considered significant

Results: The total prevalence of C. trachomatis infection was 38[17.43%] in endocervical swabs of women. However, the number of cases with C. trachomatis infections was 25 out of 109[22.9%] in the case group and 13 out of 109[11.9%] in control group, respectively. Association between chlamydia infection and spontaneous abortion was statistically significant [OR=2.198, CI 95%: 1.058-4.56]

Conclusion: Our study showed that C. trachomatis infection was associated with spontaneous abortion. Thus, screening and treatment of pregnant women may prevent this adverse pregnancy outcome

Survey on association between mycoplasma hominis endocervical infection and spontaneous abortion using polymerase chain reaction

Background: Mycoplasma infections are suggested as etiology of adverse pregnancy outcomes

Objective: The aim of this study was to evaluate the association of Mycoplasma hominis [M. hominis] infection and spontaneous abortion among pregnant women

Materials and Methods: In this case-control study that was conducted from August 2012 to January 2013, totally, 109 women were included with spontaneous abortion with gestational ages of 10-20 weeks [Cases], and 109 women with normal pregnancy with gestational ages between 20-37 weeks [Controls] in Sanandaj, Iran. Using specific primers and extracted DNA from endocervical swabs, a PCR test was conducted for detection of M. hominis infection in women. For comparison of qualitative and quantitative variables, independent Fisher tests were used and p<0.05 was considered significant

Results: The total frequency of M. hominis infection was 6 [2.75%] in women. The frequency of M. hominis infection was 2 [1.83%] in the case group [spontaneous abortion] and 4 [3.66%] in the control group, respectively. In both case and control groups, no association was seen between M.hominis infection and spontaneous abortion [OR=0. 49, CI 95%: 0.08-2.73, p=0. 683]

Conclusion: M. hominis was positive in the genital tract of some pregnant women, but it was not associated with spontaneous abortion. However, to prevent adverse pregnancy outcomes in women, foetus and neonate, routine screening and treatment for the genital Mycoplasma is recommended
