Insights
For patients with chronic hepatitis C (CH-C), moderate alcohol consumption significantly increases the risk of overall and liver-related mortality. This study highlights the detrimental effects of alcohol on CH-C patient outcomes.
Area of Science:
- Hepatology
- Public Health
- Epidemiology
Background:
- The long-term effects of moderate alcohol intake in chronic hepatitis C (CH-C) patients are debated.
- Understanding these effects is crucial for patient management and public health strategies.
Purpose of the Study:
- To investigate the impact of moderate alcohol consumption on long-term mortality in CH-C patients.
- Utilizing population-based data to provide robust evidence on this association.
Main Methods:
- Analysis of the NHANES III-mortality linked files.
- Quantification of alcohol consumption in grams per day.
- Application of multivariate Cox proportional hazards models to assess mortality risks.
Main Results:
- CH-C patients exhibited elevated risks for both overall and liver-related mortality.
- Moderate (1-19 g/day) and heavy (≥30 g/day) alcohol consumption amplified these mortality risks in CH-C patients.
- Increased overall mortality risk was observed with moderate and heavy alcohol consumption in CH-C patients.
Conclusions:
- Chronic hepatitis C independently increases mortality risks.
- Alcohol consumption, even at moderate levels, exacerbates mortality risks in CH-C patients.
- Avoiding alcohol is critical for improving long-term outcomes in individuals with CH-C.
Background:
The impact of moderate alcohol consumption on long-term outcomes of chronic hepatitis C (CH-C) infected patients remains controversial.
Aim:
To assess the impact of moderate alcohol consumption on long-term outcomes of CH-C patients using population-based data.
Methods:
Data were obtained from the Third National Health and Nutrition Examination Survey (NHANES III)-mortality linked files. Alcohol consumption was estimated as grams/day. Multivariate Cox proportional hazards model was utilized to assess the effects of CH-C and alcohol consumption on mortality (all causes, cardiovascular disease, and liver disease).
Results:
A total of 8985 participants were included as the study cohort. Of these, 218 had CH-C. The follow-up time was 162.95 months for CH-C and 178.27 months for controls. CH-C patients had increased risk for both overall mortality and liver-related mortality. CH-C patients with excessive alcohol consumption had even higher risks for overall mortality and liver-related mortality. The risk of overall mortality associated with CH-C increased with moderate alcohol consumption of 1-19 g/day and heavy alcohol consumption ≥30 g/day.
Conclusion:
Although chronic hepatitis C is associated with increased risks for overall and liver-related mortality, these risks are even higher for patients consuming moderate and excessive amounts of alcohol.
