Abstract

Background: Acute liver failure (ALF) is a rare but severe, life-threatening, complex, multisystemic gastroenterological emergency. Its rapid progression and high mortality demand early diagnosis and expert management. Drug-induced ALF (DI-ALF) remains the uncommon cause of ALF in India. To date, there is no established treatment for DI-ALF other than liver transplantation and little is known about the use of N-acetylcysteine (NAC) in DI-ALF. A prospective case-control study was carried with the aim to determine the effect of NAC on mortality of DI-FHF patients and also to evaluate the safety and efficacy of NAC use.

Methods: A total of 18 patients with a diagnosis of DI-FHF were included in the study. 10 patients received NAC infusion for 72 hours whereas the control group received placebo. The variables evaluated were demographic, signs and symptoms, biochemical parameters, outcome and length of hospital stay.

Results: Out of 18 DI-FHF patients, 13 (72.2%) had anti-tuberculosis therapy (ATT) induced FHF and 5 (27.8%) patients had ayurvedic induced FHF. The two groups were comparable for the various baseline characteristics (age, INR, alanine aminotransferase, creatinine, albumin, grade of encephalopathy, etc.). The mortality decreased to 20% with the use of NAC versus 75% in the control group (P=0.023). Use of NAC was associated with a shorter length of hospital stay of survived patients (P=0.043). Moreover, the overall survival was improved by NAC (P=0.023) in DI-FHF. ATT induced FHF showed better outcome as compared to ayurvedic induced FHF use (P=0.019).

Conclusions: Author recommended the use of NAC along with conventional treatments in patients with DI-FHF in non-transplant centers while awaiting referrals. ATT induced FHF showed better outcome as compared to ayurvedic induced FHF with NAC administration and its use was safe.
