Using inductively coupled plasma source mass spectrometry (IC-PMS), we
have studied the red cell element concentrations of alcoholic patient
s (with different periods of abstinence at admission to treatment prog
ram) and 1 month thereafter. We found elevated red cell cesium levels
on admission but not at 1-month follow-up. The elevated levels were si
gnificantly related to mean corpuscular volume. These changes are cons
istent with previous studies showing elevated red cell cesium in alcoh
olic patients but do not confirm a persistence of this abnormality ove
r time.
