RESUMEN
This case report delves into the intricate challenges of managing tuberculosis (TB) in a 70-year-old male with decompensated chronic liver disease (DCLD) and a history of endoscopic variceal ligation. The patient, initially presenting with symptoms such as black-colored stools, breathlessness, and weight loss, was diagnosed with right-sided pneumonia alongside DCLD. Despite the administration of standard beta-lactam plus macrolide antibiotics, the patient exhibited no improvement. Subsequent bronchoscopy revealed Mycobacterium tuberculosis (MTB), prompting the initiation of first-line anti-tubercular therapy. However, the hepatotoxic response necessitated a switch to a modified regimen with non-hepatotoxic drugs, emphasizing the challenge of managing TB in cirrhotic patients. Effective management of MTB infection involves personalized administration of anti-TB drugs, taking into account the individual's chronic liver disease status. This case underscores the importance of treating tuberculosis in liver cirrhosis patients based on the Child-Turcotte-Pugh score. A tailored and vigilant approach is indispensable for the successful management of MTB infection.
