Corticosteroid therapy is linked with a lower incidence of renal injury in severe alcohol-associated hepatitis.
A new analysis of patients with severe alcohol-associated hepatitis suggests that corticosteroid therapy may noticeably minimize the risk of developing acute kidney injury (AKI)—one of the most serious and life-threatening complications in this high-risk population. Laura Buttler and other researchers carried out a post-hoc analysis of the prospective, multicenter VTL-308 trial, which included 151 patients diagnosed with severe alcohol-associated hepatitis. The study evaluated:
AKI Significantly Increases Mortality
The analysis revealed that AKI was independently associated with markedly higher 90-day mortality. Patients who developed AKI had an almost 9-fold increased risk of death within 90 days (subdistribution hazard ratio [sHR] = 8.74), underscoring AKI as a devastating complication in severe alcohol-associated hepatitis.
Bilirubin Levels Predict AKI Risk
Higher baseline bilirubin levels were independently linked with an increased risk of developing AKI (sHR = 1.06). Elevated bilirubin was also linked to a lower likelihood of AKI reversal, highlighting the prognostic value of liver dysfunction markers in forecasting renal outcomes.
Corticosteroids Linked to Lower AKI Incidence
Importantly, corticosteroid therapy was related to a considerably reduced risk of AKI development. In multivariate competing risk analysis, corticosteroid use lowered AKI risk by more than 50% (sHR = 0.47). Time-censored analyses further strengthened this finding, demonstrating a protective connection between corticosteroids and AKI (HR = 0.25).
No Benefit in AKI Recovery
Despite their protective effect in preventing AKI onset, corticosteroids did not improve renal recovery once AKI had occurred (HR = 1.15). This indicates that while steroids may help prevent kidney injury, they do not reverse established renal dysfunction.
The study strengthens the evidence supporting corticosteroid therapy in severe alcohol-associated hepatitis, suggesting potential renal protective effects beyond liver-specific benefits. However, more prospective trials are needed to substantiate these outcomes and further clarify the mechanisms underlying AKI prevention.
