Beneficial effect of corticosteroids for patients with severe drug-induced liver injury.

OBJECTIVE: The efficacy of corticosteroids in drug-induced liver injury (DILI) remains controversial. We aimed to determine whether corticosteroids were beneficial for severe DILI. METHODS: This was a single-center retrospective study of patients with DILI enrolled between January 2010 and May 2015. RESULTS: Of the 203 patients enrolled, 53 were treated with corticosteroids. The baseline characteristics of patients received corticosteroids were more severe than that of the non-corticosteroid group. Subgroup analyses indicated that almost all patients who died had the higher 50% quartile of total bilirubin (TB) levels. Among the 50-75% quartile of TB level, no patient in the corticosteroids group but 3 (15.0%) of 20 patients in the non-corticosteroid group died (P = 0.261). With the highest 25% quartile of TB level, four patients in the corticosteroids group and four in the non-corticosteroids group died (P = 0.405). Corticosteroid therapy improved the recovery rate from 77.4% to 87.9% in the higher 50% quartile of TB values (P = 0.331). More interestingly, corticosteroid administration hastened the resolution of liver injury by shortening the duration of peak TB to 50% reduction from 17 to 12 days (P < 0.05). Additionally, multivariate analysis revealed that the TB levels and cholestatic injury type were the two independent factors associated with a poor outcome of DILI. CONCLUSIONS: Corticosteroids are not detrimental to DILI, but instead ameliorate liver injury and improve patient survival. Short-time use of corticosteroids is strongly recommended for severe DILI patients with hyperbilirubinemia.
