BACKGROUND: Tuberculosis (TB) drug-induced liver injury (TB-DILI) usually occurs within 8 weeks of anti-tuberculosis drug initiation. In Singapore, we suspected that the onset of TB drug-induced transaminitis may be confounded with hepatitis C virus (HCV) and hepatitis B (HBV) virus co-infection.
OBJECTIVE: To determine the impact of HCV/HBV co-infection on the course of treatment in patients with TB treatment interrupted due to transaminitis.
DESIGN: TB patients with treatment interruption during 2013-2014 were identified through the Singapore national TB registry. Case notes of those with transaminitis were perused.
RESULTS: Of 3860 TB patients notified, 140 had suspected TB-DILI. Of these, respectively 20/140 (14.3%) and 16/140 (11.4%) were HCV- or HBV-positive. The median time to treatment interruption/transaminitis was 5 weeks vs. 9.9 weeks and 9.6 weeks for transaminitis patients without chronic liver disease and with HCV/HBV co-infection (P < 0.01). Multivariate logistic regression analysis revealed that having HCV/HBV co-infection was associated with treatment interruption occurring beyond 8 weeks (adjusted OR [aOR] 4.06, 95%CI 1.28-12.85); HCV transaminitis patients were more likely to take 10 months to complete anti-tuberculosis treatment (aOR 5.11, 95%CI 1.21-21.67) than those without chronic liver disease.
CONCLUSION: TB treatment interruption due to transaminitis in HCV/HBV co-infected patients occurred later than in those without liver disease. Most had completed 2 months of pyrazinamide-containing intensive phase treatment before the onset of transaminitis.
