O98.012

Clinical Causes: Transmission of Mycobacterium tuberculosis via respiratory droplets from an infected person Reactivation of latent TB infection during pregnancy due to immune changes Prior exposure or infection with tuberculosis before pregnancy Inadequate treatment or completion of TB therapy prior to pregnancy Living in areas with high TB prevalence or close contact with someone with active TB

Key Symptoms: Persistent cough lasting more than three weeks Fatigue and weakness Unintentional weight loss Fever, often low-grade Night sweats Loss of appetite Chest pain or discomfort Hemoptysis (coughing up blood) in advanced cases

Diagnosis Path: The diagnosis of tuberculosis complicating pregnancy during the second trimester involves a combination of clinical assessments and laboratory tests. These include: - Medical history review and symptom evaluation - Tuberculin skin test (Mantoux test) or interferon-gamma release assay (IGRA) - Chest X-ray with proper abdominal shielding to minimize fetal exposure - Sputum smear microscopy and culture to identify Mycobacterium tuberculosis - Additional imaging or blood tests as needed Early detection is crucial for initiating appropriate treatment while minimizing risks to both mother and fetus.

Treatment Protocols: Management of TB during pregnancy involves a carefully planned combination of antibiotics and supportive care. Key considerations include: - Initiation of a four-drug anti-TB regimen, typically including isoniazid, rifampicin, ethambutol, and pyrazinamide, tailored to pregnant women - Regular monitoring of treatment response and side effects - Supplementation with vitamins and nutritional support - Close obstetric follow-up to monitor fetal development - Infection control measures to prevent transmission Treatment duration generally lasts for at least six months, with ongoing assessments to ensure both mother and baby remain healthy throughout pregnancy.
