Frequency of Chlamydia trachomatis in Endocervical Samples of Women Referred to a Gynecology Hospital in Qazvin, Iran

Results: Out of the 240 female participants, 184 (76.7%) were symptomatic and 56 (23.3%) were asymptomatic cases. The mean age of cases was 37.1 ± 0.9 years. Twenty (8.3%) of the 240 samples were diagnosed as Chlamydia positive according to PCR results. The prevalence of asymptomatic C. trachomatis infections was six (10.7%), while there were 14 (7.6%) in symptomatic cases. Although positive PCR results have shown in women with vaginosis (7.1%), abortion (5.1%), premature birth and low birth weight below 2.5 kg (7.7%) but the chi-square test did not indicate a significant relationship between positive PCR test results and these symptoms. Conclusions: The results of this study showed that there was a high prevalence of C. trachomatis infection among both symptomatic and asymptomatic women. Therefore, a screening test for C. trachomatis infection is recommended for all women who refer to the genitourinary medicine clinic. Screening programs are important for cost effectiveness calculations of C. trachomatis infections especially in asymptomatic cases.
