[The placental structural organization in pulmonary tuberculosis]

Area of Science:

• Obstetrics and Gynecology
• Pathology
• Perinatology

Context:

• Pregnancy complications like pulmonary tuberculosis and gestosis can affect placental development and function.
• Placental morphology and morphometry provide insights into fetal well-being and pregnancy outcomes.
• Understanding compensatory mechanisms in placental insufficiency is crucial for managing high-risk pregnancies.

Purpose:

• To investigate the morphological and morphometric characteristics of placentas in pregnant women with pulmonary tuberculosis and gestosis.
• To compare placental findings in these groups with healthy pregnant women.
• To identify the underlying causes of chronic placental insufficiency and analyze compensatory mechanisms.

Summary:

• Eighty-three placentas from women at 37-40 weeks gestation were studied. Group 1 (n=23) had pulmonary tuberculosis, Group 2 (n=40) had gestosis, and Group 3 (n=20) were healthy controls.
• Chronic placental insufficiency, characterized by abnormal villous immaturity, impaired differentiation, and angiogenesis, was observed in Group 1.
• While placental insufficiency was often compensatory, cellular mechanisms predominated in Groups 1 and 2, whereas Group 3 showed mixed vascular and cellular compensation.

Impact:

• This study highlights the specific placental pathologies associated with pulmonary tuberculosis and gestosis during late-term pregnancy.
• Findings suggest distinct adaptive strategies employed by the placenta in response to different pathological conditions.
• Understanding these differences can inform clinical management and potentially improve outcomes for pregnancies complicated by these conditions.
