{Reference Type}: Case Reports {Title}: A Case of Tubercular Pericardial Tamponade With Anti-tuberculosis Treatment-Induced Hepatitis. {Author}: Hijam D;Supongbenla S;Soram D; {Journal}: Cureus {Volume}: 16 {Issue}: 4 {Year}: 2024 Apr 暂无{DOI}: 10.7759/cureus.59050 {Abstract}: Pericarditis can be a common complication of tuberculosis (TB) in developing countries like India. It is associated with fever, fatigue, and weight loss and can often be accompanied by shortness of breath and chest pain. Other common causes of pericardial effusion include malignancy, renal failure, autoimmune disease, and viral and bacterial infections. When the pericardial fluid is bloody, TB is likely to be present in developing countries. It can often get complicated with cardiac tamponade, which has a high mortality rate. We present a case of a 55-year-old female with no co-morbidities who presented with shortness of breath, fatigue for two weeks, and chest pain for one week. She had no history of fever, chills, or rigour, and no history of TB contact. Clinical examination revealed low blood pressure with raised jugular venous pressure (JVP). Her electrocardiography (ECG) showed sinus tachycardia with a low-voltage complex. Echocardiography (ECHO) showed a large pericardial effusion, compromising ventricular function. We performed pericardiocentesis, drained 1.4 L of bloody fluid, and sent the pericardial fluid for analysis. Pericardial fluid adenosine deaminase (ADA) and cartridge-based nucleic acid amplification testing (CBNAAT) came positive for Mycobacterium TB. The patient was started on anti-tubercular treatment (ATT) and broad-spectrum antibiotics with drainage. Other routine investigations and autoimmune immune workups were normal. The patient also developed ATT-induced hepatitis, for which modified ATT was initiated. The patient improved clinically and symptomatically, was discharged, and was advised to follow up in the outpatient department (OPD).
