Background Prednisolone is considered the cornerstone treatment for severe alcoholic hepatitis (AH). However, its use limited by increased risk of infection in an already immunocompromised patient population. Among patients with AH, there exists a group non-responders who do not benefit from prednisolone therapy. Day-4 Lille score widely employed prognostic model used to identify this non-responder subgroup. The present study evaluates ability inflammatory marker, neutrophil-lymphocyte ratio...
