A prospective study of outcome in infertility patients diagnosed with genital tuberculosis

Background: Tuberculosis is an increasing health problem worldwide with around 9.6 billion new cases reported every year. Female genital tuberculosis (FGTB) has a varying incidence ranging from a very low of 0.69% in developed nations to as high as 19% in developing nations like India. The average incidence of infertility due to tuberculosis is 5-10% worldwide.Methods: The study was a hospital based prospective clinical study, from September 2014-2017 with sample size of 355 infertility cases. Endometrial sampling and diagnostic hystero-laparoscopy were used for diagnosis. Endometrial sample subjected for both the test CBNAAT and HPR was used for confirmation of positive patients. Inclusion criteria were, infertile patients diagnosed with genital tuberculosis who were then given treatment. Patients diagnosed to have infertility due to causes other than TB were excluded from the study. Highly suspected cases and those who were willing underwent diagnostic laparoscopy.Results: Out of 355 cases of infertility, 83 were because of genital TB, received treatment out of which 32 conceived.  CBNAAT was very sensitive than histopathology or laparoscopy. The live birth rate and conception rate were 20.24% and 38.09 % respectively.Conclusions: CBNAAT is OPD based economical test (free by GOI), very sensitive and picked up more cases than histopathology or laparoscopy. The live birth rate and conception rate were found to be higher than other studies possible due to intervention at an earlier stage of the disease process. This test should be widely used by gynecologist for early detection of genital tuberculosis.

Prevalence of Genital Tuberculosis in Infertile Women; a Study from a Tertiary Care Center in North India

Introduction: Female genitourinary tuberculosis (FGTB) is an important cause of infertility in women of reproductive age group. The disease remains undetected due to its asymptomatic nature and lack of sensitive tests. This study was conducted with the aim of detecting the prevalence of genital tuberculosis in infertile women. Material and methods: Endometrial curetting of 193 infertile women suspected of genital tuberculosis were taken laparoscopically and sent for histopathological examination, ZN staining, culture on LJ media and GeneXpert testing. Results: Out of 193 women, 13 were positive for Mycobacterium tuberculosis making the overall prevalence of FGTB in infertile women to the extent of 6.73%. Of these 11 presented with primary infertility while 2 patients presented with secondary infertility. The histopathological examination of all the samples was non-specific. No case of positive acid fast bacilli on ZN staining was observed. Comparison of culture and GeneXpert revealed that Xpert assay was more sensitive in detecting the positive cases. Conclusion: Our study concluded that FGTB is common in our population and women presenting with infertility should be evaluated for genital tuberculosis. A high degree of suspicion and combination of histopathological and microbiological tests are important methods for the detection of genital tuberculosis

Evaluation of genital tuberculosis as a cause of female infertility in a tertiary care hospital in North India

Background: Female genital tuberculosis (FGTB) poses a great diagnostic challenge in women of reproductive age. It causes significant morbidity or short and long term sequelae, especially infertility. The disease often remains silent or may present with non-specific symptomatology. As a result, the prevalence of genital tuberculosis is largely underestimated. A high degree of suspicion aided by intensive investigations is important in the diagnosis of the disease, especially in its early stage, so that treatment may improve the prospects of cure before the tubes are damaged beyond recovery. Objectives were to find out the prevalence of genital tuberculosis in females presenting with infertility in a tertiary care hospital over a given period of time, and diagnostic comparison of endometrial tuberculosis by histopathological examination (HPE) and GeneXpert.Methods: The prospective observational study was conducted over one year duration. A total of 96 endometrial samples were collected from the women, satisfying the inclusion and exclusion criteria.Results: On HPE, out of 96 patients, proliferative endometrium (anovulatory) was found in 38 cases (39.6%), non-specific endometritis in 2 cases (2.08%) and 2 cases (2.08%) were found positive for tubercular endometritis. GeneXpert scored negative in our study.Conclusions: Endometrial biopsy shows not only the tuberculous endometritis, but also gives additional information about local factors of endometrium concerning non-specific and specific infections and anovulatory cycles. GeneXpert if positive on endometrial biopsy is a reliable test for FGTB and treatment can be started on its basis

Female genital tuberculosis: Revisited

Female genital tuberculosis (FGTB) is caused by Mycobacterium tuberculosis (rarely Mycobacterium bovis and/or atypical mycobacteria) being usually secondary to TB of the lungs or other organs with infection reaching through haematogenous, lymphatic route or direct spread from abdominal TB. In FGTB, fallopian tubes are affected in 90 per cent women, whereas uterine endometrium is affected in 70 per cent and ovaries in about 25 per cent women. It causes menstrual dysfunction and infertility through the damage of genital organs. Some cases may be asymptomatic. Diagnosis is often made from proper history taking, meticulous clinical examination and judicious use of investigations, especially endometrial aspirate (or biopsy) and endoscopy. Treatment is through multi-drug antitubercular treatment for adequate time period (rifampicin, isoniazid, pyrazinamide, ethambutol daily for 60 days followed by rifampicin, isoniazid, ethambutol daily for 120 days). Treatment is given for 18-24 months using the second-line drugs for drug-resistant (DR) cases. With the advent of increased access to rapid diagnostics and newer drugs, the management protocol is moving towards achieving universal drug sensitivity testing and treatment with injection-free regimens containing newer drugs, especially for new and previously treated DR cases.

Loop‑mediated isothermal amplification assay for detection of Mycobacterium tuberculosis complex in infertile women.

Background: Female genital tuberculosis (FGTB) has a profound impact on the reproductive health of patients including infertility. Conventional diagnostic techniques have low sensitivity and specificity as well as long turnaround time. There is a need of developing newer, rapid and practically adaptable technique, especially in low‑income countries. Objective: To standardize and evaluate loop‑mediated isothermal amplification (LAMP) technique for diagnosis of FGTB. Methods: A total of 300 endometrial biopsy samples from infertile females were subjected to Ziehl–Neelsen (ZN) staining, Lowenstein–Jensen culture, automated culture (BACTEC mycobacterial growth indicator tube), histopathological examination (HPE), nucleic acid amplification by polymerase chain reaction (PCR) and LAMP technique. Composite gold standard (either smear/culture/HPE/PCR positive) was considered for calculation of outcome parameters. Results: The observed sensitivities of ZN smear, culture, HPE, PCR and LAMP were 2.94%, 10.29%, 8.82%, 95.59% and 66.18%, respectively. Overall concordance between PCR and LAMP was 63%, which shows a good agreement. Conclusion: This study is the first to evaluate LAMP in the diagnosis of FGTB and found it to be a rapid and convenient technique, especially in low resource endemic settings.

Endometritis tuberculosa sin foco primario y dolor pélvico crónico / Tuberculous endometritis with no primary focus and chronic pelvic pain

Antecedentes: La tuberculosis genital y la endometritis tuberculosa es una forma de tuberculosis que continúa siendo frecuente en los países en desarrollo y habitualmente es secundaria a un foco primario pulmonar. Puede cursar de forma asintomática, o bien, producir síntomas como infertilidad primaria o secundaria, alteraciones menstruales o dolor pélvico crónico, entre otros. Caso clínico: Se presenta el caso de una paciente de 47 años en estudio por ginecología y urología por dolor pélvico crónico y sintomatología urinaria inespecífica de aproximadamente 6 meses de evolución. La ecografía transvaginal muestra contenido intracavitario escaso sugerente de piometra e imágenes trabeculares compatibles con sinequias uterinas. Mediante aspirado endometrial se extrae pus y muestra endometrial que se remite para estudio anatomopatológico. Tras el informe anatomopatológico que diagnostica inflamación crónica granulomatosa necrotizante, se solicita estudio por PCR y cultivo para micobacteriumm tuberculosis, siendo ambos positivos para el microorganismo. De este modo, se diagnosticó como endometritis tuberculosa sin existir afectación de otros órganos tras el estudio completo. Se realizó tratamiento con etambutol hidrocloruro, isoniacida, pirazinamida y rifampicina durante 2 meses y pirazinamida e isonicida durante 7 meses adicionales. Al final del tratamiento, la paciente mostraba clara mejoría de los síntomas y a la ecografía desaparición de la colección intracavitaria uterina.

Background: Genital tuberculosis and endometritis tuberculosa is a form of tuberculosis which remains prevalent in developing countries and is usually secondary to a pulmonary primary focus. It may be asymptomatic, or may produce symptoms such as primary or secondary infertility, menstrual disorders or chronic pelvic pain, among others. Clinical case: We present the case of a patient of 47-year who was studied by ginecology and urology for chronic pelvic pain and unspecific urinary symptoms since about 6 months. In transvaginal ultrasound pyometra and trabecular images compatible with uterine synechiae were observed. Endometrial samples were obtaining and sent for histopathologic examination which was informed of chronic necrotizing granulomatous inflammation. We asked for PCR and culture for tuberculosis micobacteriumm, both being positive for the microorganism. Thus, she was diagnosed of endometritis tuberculosa without involvement of other organs after complete study. She performed a treatment with ethambutol hydrochloride, isoniazid, rifampicin and pyrazinamide for 2 months and pyrazinamide and isoniazid for 7 months. At the end of treatment, the patient showed clear improvement of symptoms and disappearance of uterine intracavitary collection in the ultrasonographic study.
