Introduction: Chlamydia trachomatis is one of the causes of sexually transmitted bacterial disease (STD’s) causing genital infection in the world. Many countries have expanded the strategies to investigate, diagnose and manage this curable, but prevalent and indolent disease. Most severe consequence in women is pelvic inflammatory disease (PID) and infertility. This study was designed to detect Chlamydia trachomatis infection and to correlate the infection with various risk factors in the symptomatic females attending the gynecology OPD at Dhiraj Hospital, Piparia, Vadodara, Gujarat, India
Methodology: From September 2016 to November 2016, 50 consecutive symptomatic women of reproductive age were screened for the presence of Chlamydia antigen. Endocervical swabs were collected and tested using Immunochromatographic immunoassay.
Results: The limited number of cases of infertility and PID investigated did not reveal any positive case of Chlamydia antigen from endocervical swabs.
Conclusion: Accurate diagnostic tests like NAAT and ELISA are required instead of point-of-care test to prove its role in PID and infertility.
Keywords: Chlamydia trachomatis, Endocervical swabs, Immunochromatograhic test , Pelvic Inflammatory Disease (PID)

| Introduction|| |
According to CDC (Center for Disease Control and Prevention, Atlanta) Chlamydia trachomatis is one of the most commonly detected sexually transmitted bacterial pathogen. In women, Chlamydial infections (80% being asymptomatic), are of epidemiological and clinical significance.
However, the infection may sometimes lead to mucopurulent cervicitis, urethritis, salpingitis, endometritis and ectopic pregnancy. Ascending intraluminal spread of organism causing mucopurulent cervicitis from cervix may produce pelvic inflammatory disease (PID). During pregnancy, it may result in chorioamnionitis, premature membrane rupture, premature delivery and also an increased risk of cervical carcinoma. They are also associated with 3 to 4fold increased risk of HIV transmission., From 1987 to 2003, incidence of Chlamydia infections in women has increased noticeably from 79 to 467 per 100,000. World Health Organization (WHO) has reported that about 101 million new Chlamydia infections are detected worldwide every year. As Chlamydia infections are commonly asymptomatic or cause mild or nonspecific symptoms and signs as well as the rate of Chlamydia infections around the world have been hiking over the last decade. Hence, routine screening of women at high risk of chlamydial infection is advisable in any health care set up. Usually the genital C. trachomatis infection is diagnosed by specific tests like NAAT, ELISA etc. Therefore, a point-of-care test is needed to detect C. trachomatis infection early and prevent severe sequel. Also infected patient, unaware of its infection, may serve as a reservoir of infections to their partners. Therefore there is a need to screen women for Chlamydia infection so that the treatment strategies can be planned and reduce the menace of the disease.
| Methodology|| |
Subjects: 50 consecutive women of reproductive age, who attended the Obstetrics and Gynecology Outpatients Department of our tertiary care centre, were included in this prospective cross- sectional study. The study was initiated only after approval of Institutional Ethics Committee. Study period was of three months from September 2016 to November 2016. A standard questionnaire including age, chief complaints ( if leucorrhoea , duration, amount, odour, itching), associated complaints (abdomen pain, urinary complain, dysparunea, etc), educational status, socioeconomic background, occupation, menstrual history, marital status, obstetric history, sexual activity, contraceptive history, previous history of any STD and medicines taken was asked to every patient. The study was explained to each patient in detail and a written consent was obtained from them.
Specimen (Endocervical swabs) collection (Done by the gynecologist): Bivalve speculum was used to visualize cervix while examining the patient in lithotomy position. To begin with, excess mucus was removed using first swab provided in the kit moistened with sterile physiological saline. Then, the second swab was inserted approximately 1 cm in to the cervical canal and rotated for 15-20 seconds before withdrawing. The swab was removed taking care that it does not touch the vaginal surface and was placed in the sample collection tube. The specimens were immediately used for testing.
Material: “SD BIOLINE Chlamydia” test kit (manufactured by Standard Diagnostics, Republic of Korea) was used, which is a solid phase Immunochromatographic assay to detect Chlamydia antigen qualitatively, rapidly and directly from the endocervical swab.
Principle: SD Bioline Chlamydia encloses a membrane strip, coated on test kit band region with mouse monoclonal anti-Chlamydia tracomatis. A visible line is formed by the complex of Chlamydia antigen and mouse monoclonal anti-Chlamydia tracomatis-colloid gold conjugate as it moves along the membrane chromatographically towards the test region. This line indicates a positive result in just 15 minutes [Figure 1]. SD Chlamydia kit has the sensitivity of 93% and specificity is 99% when the results were compared with the cell culture.

[Table 1] summarizes the demographic characteristics of the participants. Most of the females were middle aged, hindus, educated only till primary level and of low socio economic class. [Table 2] summarizes the symptom profile of all 50 participants where majority of the females came with the complain of White discharge with Redness, itching and burning in genital area (56%), followed by discharge with dysmenorrhea (18%). clinically 76% of the women were diagnosed with pelvic inflammatory disease, 14% cases recurrent abortion and 6% cases with infertility [Table 3].
We tried to correlate all this risk factors with the presence of Chlamydia infection, but we could not find a single positive case for Chlamydia in the subjects recruited for this study.
| Discussion|| |
The real incidence of Chlamydia infection in developing countries is difficult to establish due to several factors like socio cultural shyness, unavailability of facility to detect the organism in many health clinics and asymptomatic nature of the disease., Despite these limitations, high prevalence of Chlamydia infection has been reported in India. Reliable laboratory methods available presently for detecting Chlamydia include cell culture, NAAT and ELISA. However, it has been found that there is a wide variation in the cost, sensitivities and specificities of these methods. As a result of the different methods used for Chlamydia detection and different characteristics of the study population there is a wide variation in prevalence rates of Chlamydia infection. Several authors from different states in our country have reported wide variation in the prevalence which ranges from 0.8%-30% [Table 4].
The incidence of Chlamydia infection in the present setting was found to be 0%. There could be several explanations for this observation; one could be the low sample size (n=50) to prove any relation, secondly the diagnostic methods used in different set up are usually of high sensitivity and specificity- NAAT and ELISA [Table 4], which is not feasible to perform as a short term student research, thirdly the performance evaluation of Point-of-Care test is low compare to NAAT, may lead to false negative results. Author like Vidvan et al  have reported that NAAT is superior to the RDT (rapid diagnostic test) in diagnosing Chlamydia in a low prevalence setting. The rapid tests offer an advantage over conventional laboratory tests only in a high prevalence setting and when results are required immediately for patient management. Benefits to the patients include diagnosis and treatment at the same visit, thus eliminating the problem of repeat visits and loss to follow up.
| Conclusion|| |
Accurate diagnostic tests like NAAT and ELISA are required instead of point-of-care test to prove the role of chlamydia trachomatis in PID and infertility. Furthermore, screening of Chlamydia should be incorporated as a part of routine antenatal screening tests to prevent adverse pregnancy and neonatal outcomes.
