Case of delayed diagnosis of combined urogenita and pulmonary tuberculosis in a patient with abnormal uterine bleeding

According to the World Health Organization tuberculosis remains a global health issue for both adult and pediatric populations worldwide. Among women the peak incidence occurs during the active reproductive age, with pregnant women being 1.5–2 times more likely to be affected and experience more severe symptoms than non-pregnant women. In the Altai Region, the epidemiological situation of tuberculosis is characterized by instability, with the incidence rate among women reaching 30.5 per 100 000 of the corresponding population in 2022. Delayed diagnosis and treatment can lead to serious complications, including fatal outcomes for both mother and fetus. This article describes a clinical observation of a case of urogenital and pulmonary tuberculosis diagnosed three months after premature abdominal delivery. The course of pregnancy was complicated by acute pleuritis at 13–14 weeks, however, negative results of bacteriological culture of pleural fluid led to the absence of specific tuberculosis treatment and the development of chronic subcompensated placental dysfunction. Three months after delivery, a 34-year-old patient was admitted to the gynecological department of the emergency hospital with abnormal uterine bleeding. The diagnosis was confirmed by histopathology of an endometrial sample revealing tuberculous granulomas without caseous necrosis with epithelioid giant cells of Pirogov – Langhans. Subsequently, generalized tuberculosis was diagnosed in the preterm infant. The negative impact of undiagnosed combined urogenital and pulmonary tuberculosis on the course and outcome of pregnancy is demonstrated, including the development of anemia, placental dysfunction, preterm delivery, puerperal complications, and adverse perinatal outcomes.
