Alcohol abuse is known to increase erythrocyte mean cell volume mainly
as a consequence of direct toxic effect on the developing red cell. T
he influence of alcohol on other red cell parameters is unclear. The o
bjective of this cross-sectional survey was to examine the consequence
s of different alcohol amounts on red cell parameters among women. We
compared red cell parameters between female alcoholics, heavy drinkers
, and controls. Controls (n = 138) and heavy drinkers (n = 65) consist
ed of consecutive 40- and 45-year-old women participating in the healt
h screening, and alcoholics (n = 73) of consecutive women coming to a
detoxification clinic. Alcoholics had significantly smaller erythrocyt
e counts (p < 0.01), end higher erythrocyte mean cell volume values (p
< 0.001), reticulocyte counts (p < 0.01), and red cell distribution w
idth values (p < 0.001) than controls. No difference between these gro
ups was found, however, in hemoglobin distribution width value. The on
ly red cell difference between controls and heavy drinkers was erythro
cyte mean cell volume, which was significantly higher among heavy drin
kers(p < 0.001). In alcoholics, red cell distribution width values wer
e even more often increased (in 44%) than erythrocyte mean cell volume
values (in 34%). This increase in red cell distribution width was not
solely explained by iron deficiency or liver disease. Chronic alcohol
abuse not only affects erythrocyte mean cell volume values, but also
leads to anisocytosis seen in blood count as an increased red cell dis
tribution width value.
