Malnutrition Severity Predicts Clinical Outcomes in Alcoholic Hepatitis: Evidence from National Data

Area of Science:

• Hepatology
• Internal Medicine
• Nutritional Science

Background:

• Alcoholic hepatitis (AH) is a severe form of alcoholic liver disease (ALD).
• Malnutrition is a common complication of ALD, worsening with disease progression.
• The impact of malnutrition severity on AH clinical outcomes requires further investigation.

Purpose of the Study:

• To investigate the association between malnutrition severity and clinical outcomes in patients hospitalized with AH.
• To analyze the correlation between different degrees of malnutrition and mortality, complications, and healthcare resource utilization in AH.

Main Methods:

• Retrospective analysis of adult patients admitted with AH from the National Readmission Database (NRD) 2016-2020.
• Classification of AH patients based on malnutrition severity (mild-moderate, severe, unspecified).
• Multivariate regression analysis to compare outcomes including in-hospital mortality, septic shock, vasopressor use, mechanical ventilation, ICU admission, liver complications, and resource utilization.

Main Results:

• 19% of 82,367 AH patients had malnutrition.
• In-hospital mortality increased with malnutrition severity (aOR 1.62 for mild-moderate, 3.14 for severe).
• Malnutrition correlated with higher odds of septic shock, vasopressor requirement, mechanical ventilation, ICU admission, liver complications, and increased healthcare resource utilization.

Conclusions:

• Malnutrition is a prevalent comorbidity in AH patients, directly linked to increased mortality and a spectrum of adverse outcomes.
• Nutritional status plays a critical role in AH prognosis.
• Effective management of malnutrition is essential for improving patient outcomes and reducing healthcare costs in AH.
