Abstract

Background: Cirrhotic patients are susceptible to drug toxicity, which presents frequently with antituberculosis drug (ATD) treatment. Previous studies of ATD-induced liver injury (ATDILI) in cirrhotics have been limited to patients with early-stage cirrhosis. 

Objectives: To describe characteristics and determine risk factors for ATDILI in cirrhotic patients. 

Methods: We included 64 cirrhotic patients treated with ATDs between 2006 and 2016 in a tertiary referral university teaching hospital in Bangkok, Thailand. Cirrhosis was diagnosed by radiological features, including small-sized nodular liver and/or caudate lobe hypertrophy or evidence of portal hypertension (collateral vessels, varices, and/or splenomegaly). Clinical information was retrospectively abstracted. Characteristics of patients with ATDILI vs. those without ATDILI were compared. 

Results: Six (9.4%) patients developed ATDILI with the median duration from ATD initiation of 14 days (range: 6-66). All the 6 patients who developed ATDILI received 3 hepatotoxic ATDs (isoniazid, rifampin, and pyrazinamide) and had Child-Turcotte-Pugh class B cirrhosis. The patients with ATDILI were found to have a higher percentage of human immunodeficiency virus (HIV) infection than patients without ATDILI (50% vs. 8.6%; P = 0.02). 

Conclusions: Cirrhotic patients, particularly those with underlying HIV infection, are at risk of developing ATDILI. Pyrazinamide should be used cautiously in cirrhotic patients due to the significantly increased risk of ATIDLI. This study supports the current recommendation for the use of ATD in patients with cirrhosis; however, the ATD regimen should be carefully selected, particularly for cirrhotic patients with HIV infection.
