Abstract
AIM: Genital tuberculosis (GTB) is a potent contributor to irreversible damage to the reproductive system and infertility in females. As no gold standard diagnostic tool is yet available, clinical suspicion and relatively insensitive approaches such as histopathology, laparoscopy and hysterosalpingogram are currently critical determinants in the diagnosis of GTB. Although a polymerase chain reaction (PCR)-based assay using endometrial tissue seems promising, sampling does require an invasive procedure. OBJECTIVE: We hypothesized that menstrual blood may provide an alternate non-invasive source of samples for PCR-based GTB diagnosis. METHODS: We enrolled 195 women with primary infertility in whom GTB was suspected. We obtained ethics committee approval from our institution and written informed consent from subjects. Endometrial tissue and menstrual blood was collected from the subjects and culture, histopathology, and multiplex PCR with both sample type was performed for each subject. RESULTS: The sensitivity and specificity of multiplex PCR was, respectively, 90.2 and 86.1% for menstrual blood, 95.8 and 84.3% for endometrial tissue, and 64.8 and 93.2% for histopathology staining. CONCLUSIONS: A strong clinical suspicion aided with multiplex PCR using menstrual blood may significantly reduce the diagnostic dilemma for GTB diagnosis in a non-invasive, sensitive, rapid, and cost-effective manner.
