Insights
Identifying risk factors for alcoholic hepatitis (AH) is crucial due to its high mortality. Binge drinking, heavy drinking, and cirrhosis are linked to AH, while probable AH and hypertension increase inpatient mortality.
Area of Science:
- Hepatology
- Internal Medicine
- Public Health
Background:
- Alcoholic hepatitis (AH) incidence and mortality rates are increasing.
- Abstinence is the primary factor for long-term survival in AH patients.
- Identifying individuals at risk is essential for implementing preventative strategies.
Purpose of the Study:
- To identify risk factors associated with alcoholic hepatitis (AH).
- To determine variables linked to mortality in AH patients.
- To explore potential healthcare disparities in AH outcomes.
Main Methods:
- Retrospective analysis of adult patients diagnosed with AH (ICD-10) between November 2017 and October 2019.
- Diagnosis of AH based on clinical parameters, categorized as 'probable' or 'possible'.
- Logistic regression analysis to identify risk factors for AH and mortality.
Main Results:
- Binge drinking (OR 2.698), heavy drinking (OR 3.169), and cirrhosis (OR 3.392) were significantly associated with AH.
- Probable AH diagnosis (OR 6.79) and hypertension (OR 6.51) were linked to higher inpatient mortality.
- Non-Caucasian race showed a higher mortality incidence (OR 2.72), suggesting potential healthcare disparities.
Conclusions:
- Binge drinking, heavy drinking, and cirrhosis are key risk factors for alcoholic hepatitis.
- Probable AH diagnosis and hypertension are associated with increased mortality.
- Observed disparities in mortality among racial groups warrant further investigation into healthcare access and quality.
Abstract:
The rate of alcoholic hepatitis (AH) has risen in recent years. AH can cause as much as 40-50% mortality in severe cases. Successful abstinence has been the only therapy associated with long-term survival in patients with AH. Thus, it is crucial to be able to identify at-risk individuals in order to implement preventative measures. From the patient database, adult patients (age 18 and above) with AH were identified using the ICD-10 classification from November 2017 to October 2019. Liver biopsies are not routinely performed at our institution. Therefore, patients were diagnosed with AH based on clinical parameters and were divided into "probable" and "possible" AH. Logistic regression analysis was performed to determine risk factors associated with AH. A sub-analysis was performed to determine variables associated with mortality in AH patients. Among the 192 patients with alcohol dependence, there were 100 patients with AH and 92 patients without AH. The mean age was 49.3 years in the AH cohort, compared to 54.5 years in the non-AH cohort. Binge drinking (OR 2.698; 95% CI 1.079, 6.745; p = 0.03), heavy drinking (OR 3.169; 95% CI 1.348, 7.452; p = 0.01), and the presence of cirrhosis (OR 3.392; 95% CI 1.306, 8.811; p = 0.01) were identified as characteristics more commonly found in the AH cohort. Further, a higher inpatient mortality was seen in those with a probable AH diagnosis (OR 6.79; 95% CI 1.38, 44.9; p = 0.03) and hypertension (OR 6.51; 95% CI 9.49, 35.7; p = 0.02). A higher incidence of mortality was also noted among the non-Caucasian race (OR 2.72; 95% CI 4.92; 22.3; p = 0.29). A higher mortality rate despite a lower incidence of alcohol use among non-Caucasian patients may indicate healthcare disparities.
