Abstract

The Drug-Induced Liver Injury Network (DILIN) studies hepatotoxicity caused by conventional medications as well as herbals and dietary supplements (HDS). To characterize hepatotoxicity and its outcomes from HDS versus medications, patients with hepatotoxicity attributed to medications or HDS were enrolled prospectively between 2004 and 2013. The study took place among eight U.S. referral centers that are part of the DILIN. Consecutive patients with liver injury referred to a DILIN center were eligible. The final sample comprised 130 (15.5%) of all subjects enrolled (839) who were judged to have experienced liver injury caused by HDS. Hepatotoxicity caused by HDS was evaluated by expert opinion. Demographic and clinical characteristics and outcome assessments, including death and liver transplantation (LT), were ascertained. Cases were stratified and compared according to the type of agent implicated in liver injury; 45 had injury caused by bodybuilding HDS, 85 by nonbodybuilding HDS, and 709 by medications. Liver injury caused by HDS increased from 7% to 20% (P < 0.001) during the study period. Bodybuilding HDS caused prolonged jaundice (median, 91 days) in young men, but did not result in any fatalities or LT. The remaining HDS cases presented as hepatocellular injury, predominantly in middle-aged women, and, more frequently, led to death or transplantation, compared to injury from medications (13% vs. 3%; P < 0.05).

Conclusions: The proportion of liver injury cases attributed to HDS in DILIN has increased significantly. Liver injury from nonbodybuilding HDS is more severe than from bodybuilding HDS or medications, as evidenced by differences in unfavorable outcomes (death and transplantation).

Case Enrollment, 2004 – 2013. The selection of cases for this report is shown. There were 1219 patients who were enrolled into the DILIN during the period from 2004 to March, 2013. Only the 847 patients who completed the causality assessment process and who were confirmed as having liver injury from a medication or HDS, that is with a definite, very likely, or probable causal association between the agent and liver injury, were eligible for this analysis. Of this group, 8 were excluded; 2 because they had injury that could have resulted from either medications or HDS and 6 because they had consumed both bodybuilding and non-bodybuilding HDS. There were remaining 709 patients in whom medications were the cause for injury, and 130 in which HDS were the cause, 45 due to bodybuilding HDS and 85 due to non-bodybuilding HDS.
