Erythrocyte mean cell volume--correlation to drinking pattern in heavy alcoholics
Acta Medica Scandinavica
|January 1, 1986
Summary
Mean cell volume (MCV) in heavy drinkers better reflects the duration and extent of recent drinking episodes than overall alcohol consumption. This finding is crucial for understanding heavy alcohol use patterns.
Area of Science:
- Clinical Medicine
- Addiction Research
- Hematology
Background:
- Erythrocyte mean cell volume (MCV) is a biomarker associated with alcohol consumption.
- However, MCV's correlation with alcohol intake is less reliable in heavy drinkers compared to moderate drinkers.
- Approximately 50% of heavy drinkers exhibit elevated MCV.
Purpose of the Study:
- To investigate the influence of drinking episode duration and extent on MCV in addictive alcoholics.
- To assess the relationship between MCV and daily alcohol intake, smoking habits, drinking duration, and total alcohol consumption during a recent drinking period.
Main Methods:
- Prospective investigation of 64 active addictive alcoholics within two weeks post-drinking period.
- Data collection included daily alcohol intake (120-480 g) and drinking duration (1-104 weeks).
- Comparison group comprised 21 non-active alcoholics.
Main Results:
- No significant correlation was found between MCV and daily alcohol consumption or smoking habits in active alcoholics.
- A significant positive correlation was observed between MCV and both the duration of the drinking episode and the total alcohol intake during that period.
- MCV did not correlate with daily intake in active alcoholics.
Conclusions:
- MCV is more valuable for estimating the duration and extent of recent drinking episodes in heavy alcoholics.
- MCV may be less effective for general screening of alcoholism in heavy drinkers compared to its utility in assessing recent drinking behavior.
