Introduction:
Infertility is a significant result of the disease load among women, particularly in poorer nations. Hematogenous or lymphatic transmission can allow the bacteria to enter the reproductive organ from the lung. Numerous people exhibit unusual symptoms at first that resemble those of other gynecological disorders. It takes multiple studies to determine the diagnosis. The majority of genital tuberculosis infections impact the fallopian tube, leading to endometrial involvement and infertility in the affected patients. Currently, tubal surgery combined with antituberculosis therapy is the mainstay of treatment.
What Is Female Genital Tuberculosis?
One of the most significant health issues facing the globe today is tuberculosis (TB). In 2017, it claimed the lives of nearly 1.5 million people and afflicted about 10 million people. Of all new cases of TB, 87 percent were found in 30 countries with an elevated TB burden. Eight nations supplied two-thirds of the total cases; India accounted for the most, followed by China, Indonesia, Philippines, Pakistan, Africa, Bangladesh, and South Africa. Although men account for 56 percent of TB infections and deaths, women also bear a disproportionately high burden of the disease. In nations where tuberculosis is highly prevalent, female genital TB (FGTB) is a primary contributing reason to infertility.
Usually, this kind of tuberculosis develops after primary pulmonary tuberculosis. Globally, the prevalence of FGTB among young women is rising. Usually, the spread occurs directly or via hematogenous or lymphatic pathways. Infertility may arise from an infection of the female genital tract with tuberculosis. Antitubercular medication is administered as part of the conventional therapy for FGTB, just as it is for pulmonary TB. Early detection of FGTB and appropriate treatment with appropriate antitubercular medication dosages can lessen the disease's effects and these women's potential infertility.
What Are the Signs and Symptoms of Female Genital Tuberculosis?
Infertility is caused by M. tuberculosis, which damages the female genital organs, particularly the fallopian tubes. Though it can affect anyone of any age, the majority of those affected are women in the reproductive age range. The condition is usually asymptomatic, although it can occasionally cause a few symptoms, the most common of which is infertility. Menstrual irregularities, including oligomenorrhea, hypomenorrhea, amenorrhea, menorrhagia, dysmenorrhea, metrorrhagia, pelvic pain, and atypical vaginal discharge, are other symptoms that have been recorded.
Genital TB in postmenopausal women can cause symptoms including pyometra, chronic leucorrhoea, and postmenopausal bleeding, which are indicative of endometrial cancer. The majority of patients have had pelvic mass, cyst, an abscess, dyspareunia, menstrual disorder, menstrual cramps, or postmenopausal bleeding in addition to chronic lower abdominal and pelvic pain. The FGTB may develop if these signs are discovered in female infertile patients.
What Is the Epidemiology and Pathogenesis of Female Genital Tuberculosis?
It is challenging to find epidemiological and clinical information about FGTB cases. There are still issues with proper diagnosis, vague clinical symptoms of the disease, and a need for clinical understanding of the possibility of FGTB. Because numerous individuals remain asymptomatic and untreated, it is challenging to determine the precise frequency of FGTB in different geographic locations and patient groups.
Improved indices are needed to adequately explain the epidemiological data of FGTB. These comprise indices for newly diagnosed FGTB cases among gynecological disease patients admitted to the hospital and FGTB cases among a population of infertile women. The incidence is much higher in developing countries than in developed countries. The percentage of 7.1 million incident cases in 2019 that were extrapulmonary TB was around 16 %.
What Is the Diagnosis of Female Genital Tuberculosis?
A variety of tests are needed to confirm the FGTB diagnosis. The patient's history, general physical examination, gastrointestinal examination, and gynecological examination are some of the ways gynecologists may begin gathering information. The two imaging modalities helpful in FGTB diagnosis are ultrasonography and hysterosalpingography (HSG). While USG enables the simultaneous examination of ovarian, uterine, and extrapelvic involvement, HSG assesses the internal anatomy of the female genital tract and tubal patency.
Even with the advent of numerous diagnostic methods, there is still a diagnostic problem, particularly with genital TB. As a result, FGTB requires rigorous investigations and a comprehensive, methodical, clinical examination with a high degree of suspicion. When genital neoplasia have been ruled out, individuals with chronic PID who are not responding to standard antibiotic treatment, infertile patients who are not responding to treatment, and women who have irregular menstrual cycles, postmenopausal bleeding, and prolonged vaginal discharge should be evaluated for the possibility of FGTB.
Contact with a smear-positive pulmonary TB patient, a history of TB infection, residing in or recently visiting endemic areas, having a low socioeconomic background, being HIV positive, and drug usage are risk factors. A single diagnostic test cannot verify the diagnosis of FGTB.
What Is the Treatment of Female Genital Tuberculosis?
The management of FGTB and pulmonary TB are comparable. The six-month therapy length, while disputed, is seen as adequate. The regimen advice for many kinds of EPTB is based on something other than data from rigorous research, unlike that for PTB. Six-month therapy is very beneficial in patients whose organisms are susceptible to first-line medications. According to the WHO treatment guidelines, patients who are recently diagnosed with tuberculosis (TB) should be treated with a regimen that includes Rifampicin (R) for six months: an intensive phase that lasts two months and involves the use of Isoniazid (H), Ethambutol (E), and Pyrazinamide (Z), followed by a continuation phase that lasts four months and involves the use of HR.
Methods to reduce the chance of contact with mycobacteria are part of the primary prevention of tuberculosis. Thus, teaching pulmonary tuberculosis patients the importance of maintaining a treatment regimen and practicing respiratory hygiene at home and in public is crucial. Adopting safe sexual practices can reduce the risk of contracting genital infections, specifically tuberculosis. BCG (Bacillus Calmette-Guérin) vaccination is a preventive measure in nations like India with a high TB burden. Though its protective efficacy varies significantly across the population, the BCG vaccine is up to 80 percent effective in avoiding the development of severe types of tuberculosis.
Conclusion:
Although the exact prevalence of FGTB disease in infertile women is unknown, it is most likely to be quite prevalent. Infertility and gynecological problems, including irregular menstruation and persistent pelvic pain, are brought on by FGTB. A comprehensive history, a clinical and gynecological examination, and several techniques to identify the presence of M. tuberculosis infection are used in the diagnosis process. Taking ATT (anti-tubercular treatment) for a long enough period at appropriate doses is the primary treatment for FGTB.
