title: Markers of genital tuberculosis in infertility.
abstract: BACKGROUND
  Although genital tuberculosis is a condition that is prevalent worldwide, it is still a diagnostic dilemma. This study aimed to find an effective diagnostic modality for the condition.
  
  
  METHODS
  A total of 100 infertile women were clinically evaluated with haemoglobin estimation, total and differential count, Mantoux test, tubercle bacilli enzyme-linked immunosorbent assay (TB ELISA), hysterosalpingography, pelvic ultrasonography, laparohysteroscopy, premenstrual endometrial biopsy for histopathology, culture and tubercle bacilli polymerase chain reaction (TBPCR). The womens' Day 2 hormonal profile (luteinising, follicle-stimulating, prolactin and thyroidstimulating hormones) and their husbands' semen analysis were also conducted.
  
  
  RESULTS
  A total of 58 women had primary infertility and 42 had secondary infertility. Female factor infertility was present in 63 percent of the cases (mostly tubal; 45.97 percent). 26 women tested positive for endometrial TBPCR. Erythrocyte sedimentation rate, Mantoux test, TB ELISA and hysterosalpingography were found to have high negative predictive value (greater than 80 percent), while the positive predictive value was 35-45 percent. Laparoscopy findings were suggestive of tuberculosis in 13 percent of the women, out of which 83.3 percent were positive for endometrial TBPCR. Hysteroscopy revealed intrauterine adhesions in 34.8 percent of the women, with 68.8 percent being positive for tubercular bacilli.
  
  
  CONCLUSIONS
  Our study established that in cases of genital tuberculosis, the use of expensive endometrial TBPCR tests may be avoided with a detailed workup, which would also help in the institution of anti-tubercular treatment in early disease, thus enhancing the chance of pregnancy.
