The impact of hepatotoxic drugs on the outcome of patients with acute deterioration of hepatitis B virus-related chronic disease

Background and aims Hepatotoxic drugs can worsen outcomes in patients with chronic liver disease (CLD), whereas this negative effect in acute deterioration of hepatitis B virus (HBV)-related CLD (HBV-CLD) is rarely reported. We aimed to assess the impact of hepatotoxic drugs on the outcome of patients with acute deterioration of HBV-CLD. Methods This retrospective study included consecutive patients admitted to three medical centers in eastern China from 2015 to 2020 for HBV-related severe liver injury (HBV-SLI) or acute decompensation of cirrhosis (HBV-AD). The prevalence of hepatotoxic drugs and their impact on organ failure, the development of acute-on-chronic liver failure (ACLF), and 90-day survival were evaluated. Results: A total of 335 patients with HBV flare (median age, 44 years; 85.7% male; 38.2% HBV-SLI and 61.8% HBV-AD) were included. Of them, 72 (21.5%) received hepatotoxic drugs, with herbs (44.4%) being the most common form. Patients in the drugs group had a significantly higher prevalence of all types of organ failure except respiratory failure. The multivariate logistic model showed that hepatotoxic drugs raised the risk of developing ACLF by 7.66-fold. ACLF occurrence was the strongest risk factor for 90-day mortality with a hazard ratio of 5.54 in the Cox regression analysis. In contrast, the hepatitis B envelope antigen status and HBV DNA levels had weak associations with the development of organ failure and ACLF. Conclusions: Hepatotoxic drugs are closely associated with the development of organ failure and ACLF, and contribute to reduced 90-day survival rates among patients with acute deterioration of HBV-CLD.

Automated summary

Hepatotoxic drugs are closely associated with the development of organ failure and ACLF among patients with acute deterioration of HBV-CLD, leading to reduced 90-day survival rates.
