Abstract

OBJECTIVE: Alcoholic hepatitis (AH) represents a severe manifestation of alcoholic liver disease (ALD) associated with a wide severity spectrum. ALD is linked to nutritional deficiencies, with the gravity of malnutrition escalating as alcohol abuse and ALD progress. This study aims to delve into the impact of malnutrition on the clinical trajectory of AH.

METHODS: We identified adult patients admitted with AH using the National Readmission Database (NRD) 2016-2020. We further classified AH patients based on the severity of malnutrition. We compared the outcomes of AH hospitalizations using a multivariate regression model.

RESULTS: We included 82,367 AH patients, of whom 15,693 (19.00%) had malnutrition. 4,243 (5.15%) patients exhibited mild to moderate malnutrition, 5,862 (7.07%) patients had severe malnutrition, and 5,588 (6.78%) patients had unspecified severity of malnutrition. We found that adjusted in-hospital mortality due to AH was higher in patients with malnutrition, corresponding to the severity of malnutrition (adjusted odds ratio [aOR] 1.62 and 3.14 in mild-moderate malnutrition and severe malnutrition, respectively; p < .01). Additionally, patients with malnutrition had progressively elevated odds of septic shock, vasopressor requirement, mechanical ventilation, and intensive care unit (ICU) admission with escalating intensity of malnutrition. Liver-related complications, such as spontaneous bacterial peritonitis, coagulopathy, hepatorenal syndrome, and hepatic encephalopathy, were also found to have an increased likelihood in the presence of malnutrition. Furthermore, resource utilization showed a progressive increase with increasing severity of malnutrition.

CONCLUSION: Our findings indicate that malnutrition is a common comorbidity in AH patients, with varying degrees of severity, which correlates with higher mortality rates, emphasizing the critical role of nutritional status in the prognosis of AH. These findings underscore the importance of addressing and managing malnutrition in patients with AH, not only for its potential contribution to mortality but also because of its association with a spectrum of complications and increased healthcare resource utilization.
