Despite better knowledge of the pathogenesis of severe alcoholic hepatitis (AH), corticosteroids are still the treatment recommended by clinical guidelines, pentoxifylline being the second-line option for non-responders to corticosteriods and for patients with contraindications. Pentoxifylline is a phosphodiesterase inhibitor with an anti-TNF effect and has been reported to reduce mortality and the incidence of hepatorenal syndrome in severe AH. After the first report, several studies, of distinct quality, have tested the efficacy of pentoxifylline in different scenarios. The conclusions of these studies are that pentoxifylline seems to improve survival in comparison to placebo but has lower efficacy than corticosteroids, with no improvement in survival when added to corticosteroids or in non-responders to steroid therapy. The role of pentoxifylline in severe alcoholic hepatitis is even more doubtful after the results of a very recent controlled study that showed no beneficial effect on survival at 1, 3 and 12 months of follow up, although a very recent network meta-analysis reported a beneficial effect of pentoxifylline alone or with corticosteroids on short-term survival. In conclusion, pentoxifylline has no clear beneficial effects in severe AH but could perhaps be used in patients with a contraindication to corticosteroids. However, the recommendations of clinical guidelines should be reconsidered and it is essential to search for new therapeutic targets for this disease.
