Moreover, the combination of steatotic liver disease and high-risk alcohol intake carried a more than 43% higher long-term risk of liver cirrhosis compared with no alcohol use, according to researchers led by Robert J. Wong, MD, MS, of the Division of Gastroenterology and Hepatology, Veterans Affairs Healthcare System Palo Alto, at Stanford University School of Medicine in Palo Alto, California.
However, the study found that “reducing alcohol use lowers risk of cirrhosis, emphasizing the importance of timely alcohol use assessment and early interventions to address high-risk alcohol use in steatotic liver disease,” Dr. Wong and associates wrote in Gastroenterology.
Although concurrent moderate to heavy alcohol intake would be expected to lead more rapidly to liver disease progression, the existing literature has been conflicting, the authors noted. Several studies have even found moderate alcohol associated with a lower risk of advanced liver disease among MASLD patients, including that by Dunn et al. .
The Study
MASLD patients were identified through the US Veterans Affairs Corporate Data Warehouse from January 1, 2010, through December 31, 2017, with follow-up through December 31, 2022.
Alcohol use was assessed by Alcohol Use Disorders Identification Test–Concise (AUDIT-C) scores and was categorized as follows: no alcohol (AUDIT-C = 0), low-risk alcohol use (AUDIT-C 1-2 for women and 1–3 for men), and high-risk alcohol (AUDIT-C ≥ 3 for women and ≥ 4 for men).
Among the 1,156,189 veterans with MASLD, 54.2% reported no alcohol, 34.6% low-risk alcohol, and 11.2% high-risk alcohol use. In median follow-up of nine to 10 years, incidence rates of cirrhosis were .53 per 100 person-years for no use, .42 for low-risk use, and .76 for high-risk use.
In contrast to patients with baseline high-risk alcohol intake who reported no change in use, those who decreased their alcohol intake during follow-up experienced a 39% reduction in the long-term risk of cirrhosis, for a hazard ratio of .61 (95% CI, .45-.83, P < .01).
About 70% of patients were non-Hispanic Whites and more than 90% were male in all consumption categories. The no-alcohol group was older than the high-risk alcohol group: 64 years vs 59.9 years (P < .0001). Compared with the high-risk alcohol group, the no-alcohol group had a significantly greater proportion of comorbid diabetes (62.3% vs 42.5%), hypertension (77.9% vs 69.1%), or cardiovascular disease (40.2% vs 25.9%, P < .0001 for all comparisons).
In a significant study observation, fewer than 5% of patients with high-risk use received behavioral or pharmacologic therapy and of those who did, most were referred for or received treatment at or near the time of cirrhosis diagnosis. “This highlights a major gap in linking patients with high-risk alcohol use to appropriate behavioral or pharmacologic therapy in a timely manner and may reflect missed opportunities to prevent further alcohol-related morbidity and mortality,” Dr. Wong and colleagues wrote.
They called for studies of novel interventions for timely assessment of alcohol use with linkage to addiction services. They cited the need to understand the interaction between levels of alcohol use and underlying MASLD, adding, “More research is also needed to understand whether this interaction varies across different populations.”
This study received no specific funding. Dr. Wong reported funding through his institution from Gilead Sciences, Exact Sciences, and Thera Technologies.
Recent consensus in defining metabolic dysfunction-associated steatotic liver disease (MASLD) has raised awareness for the combined impact of cardiometabolic risk factors and alcohol consumption on liver disease progression. This study by Wong et al. highlights the undeniable influence of high-risk alcohol use on the development of advanced liver disease.
In a national cohort of over 1 million US veterans with steatotic liver disease (SLD), patients with high-risk alcohol use based on AUDIT-C assessment exhibited > 43% greater risk of cirrhosis compared to those with no alcohol use. The relationship between alcohol and liver severity in SLD was observed even after excluding patients meeting classification for predominant alcohol-associated liver disease. While increased alcohol use was associated with increased incidence of cirrhosis, decreased alcohol use led to a notable 39% reduction in cirrhosis risk over time.
Reducing alcohol consumption remains best practice guidelines for mitigating risk of progression in steatotic liver disease. However, results of this study emphasize the critical need for early identification and treatment of high-risk alcohol use in all patients with SLD. While universal recommendations for alcohol abstinence provides pragmatic implementation, there is a significant need to better understand the interaction of specific metabolic risk factors and patterns of alcohol use across the spectrum of MetALD to guide personalized recommendations for patient education and management.
Further research using prospective clinical trial design is needed to evaluate the interplay of alcohol consumption and metabolic risk factors across variable age, sex, genetics, and environmental exposures that are increasingly being recognized as vital drivers of health and disease.
