Alcohol misuse can lead to alcohol-associated hepatitis (AH), a form of liver disease with a high short-term mortality rate in severe cases. Currently, no medications have been approved by the U.S. Food and Drug Administration to treat AH, and liver transplantation is often required due to liver failure. A better understanding of how AH develops could help improve AH treatment and prevent progression to severe disease. A recent study has shown a positive correlation among neutrophilic infiltration and the model for end-stage liver disease score (MELD score, a scoring system predicting prognosis of liver disease) and serum alanine aminotransferase (ALT) levels. Researchers found a mechanism by which neutrophils—a type of white blood cell—contribute to liver injury in AH. Published in the Journal of Clinical Investigation, the study was supported by the National Institute on Alcohol Abuse and Alcoholism.
