为含酒精的肝炎的治疗的 Corticosteroids 和 pentoxifylline : 当前的地位

The treatment of choice for patients with severe alcoholic hepatitis (AH) is use of corticosteroids.Many randomized well designed studies have been reported from all over the world on the use of corticosteroids in the treatment of AH.However,the data on the efficacy of corticosteroids in these patients have been conflicting.Initial meta-analyses also failed to show beneficial effects of corticosteroids.Based on individual data meta-analysis showing clear benefit of corticosteroids amongst patients with severe AH (modified discriminant function of 32 or more),led American College of Gastroenterology to recommend use of corticosteroids as the first line treatment option amongst patients with severe AH.However,corticosteroids are relatively contraindicated amongst patients with severe AH and coexistent sepsis,gastrointestinal bleeding,and acute pancreatitis.These patients may be candidates for second line treatment with pentoxifylline.Further,specific treatment of AH with corticosteroids far from satisfactory with as many as 40%-50% of patients failing to respond to steroids,thus classified as nonresponsive to steroids.The management of these patients is a continuing challenge for physicians.Better treatment modalities need to be developed for this group of patients in order to improve the outcome of patients with severe AH.This article describes at length the available trials on use of corticosteroids and pentoxifylline with their current status.Route of administration,dosage,adverse effects,and mechanisms of action of these two drugs are also discussed.Finally,an algorithm with clinical approach to management of patients who present with clinical syndrome of AH is described.
