Malondialdehyde as a Prognostic Factor in Alcoholic Hepatitis

AimsnAlcoholic hepatitis is a severe complication of alcoholism, associated with high short-term mortality. Although pathogenesis remains obscure, it is generally accepted that lipopolysaccharide-induced cytokine secretion with further generation of reactive oxygen species (ROS) play outstanding roles. Prognosis is uncertain, and the usually employed prognostic scores do not include variables related to ROS generation. Therefore, this study was performed to assess short-term prognostic value of cytokines, nutritional status, different scores [Maddrey, model for end-stage liver disease (MELD), albumin, bilirubin, INR, creatinine index (ABIC), Lille, Glasgow, MELD-Na, Child-Pugh] and malondialdehyde (MDA, as an indicator of lipid peroxidation) at admission and after 1 week, among patients affected by severe acute alcoholic hepatitis (Maddrey index >32).nnnMethodsnSixty-two patients affected by severe acute alcoholic hepatitis, for whom we calculated Maddrey, MELD, ABIC, Lille, Glasgow, MELD-Na, Child-Pugh, and determined serum MDA andxa0interleukin (IL)-6, IL-8, IL-4, tumor necrosis factor alpha and interferon gamma levels at admission and after 1 week.nnnResultsnTwenty-four patients died during the follow-up period. MDA showed a better prognostic accuracy than the aforementioned scores, both at admission and after 1 week.nnnConclusionnOur study supports the importance of including MDA assessment in the prognostic evaluation of patients with alcoholic hepatitis.nnnShort summarynAlcoholic hepatitis is associated with high short-term mortality. Although not included in prognostic scores, lipid peroxidation plays an outstanding role in its pathogenesis. We found that malondialdehyde levels showed a better prognostic accuracy than the usually employed scores. Therefore, it should be included in the prognostic evaluation of these patients.
