Liver transplantation is associated with good clinical outcome in patients with active tuberculosis and acute liver failure due to anti-tubercular treatment

Background: Active tuberculosis (TB) is commonly considered a contraindication for liver transplantation (LT). However, in patients with TB who develop acute liver failure (ALF) due to toxicity induced by anti-tubercular treatment (ATT), LT could be the only opportunity for treatment. The aim of this study was to evaluate the feasibility of LT in this scenario. Methods: We described 2 cases and comprehensively reviewed the literature finding 26 cases of LT performed in patients having a concomitant active TB and liver failure secondary to ATT toxicity. Results: TB was classified as pulmonary in 18/26 (69%), nodal in 3/26 (11%) TB cases, while the remaining 5/26 cases included disseminated, pleural, renal, ovarian, and vertebral TB localization (1 case each). ATT following LT consisted mainly of isoniazid or rifampin (RIF)-sparing regimens and included primarily fluoroquinolones and ethambutol. Rejection episodes and liver toxicity were reported in 19% and 8% of patients respectively. Graft rejection was more frequent among patients treated with RIF-containing regimens (P<.001). Mortality rate was 15% after a median follow up of 12 months. In only one case was death attributed to uncontrolled TB infection. Conclusion: Our findings suggest that LT is an effective therapeutic option for patients with active TB developing ALF following ATT and should be considered for patients failing medical treatment.
