[Compared efficiency of mean corpuscular volume (MCV) and serum gamma-glutamyltransferase (gamma-GT) as screening tests for excess-ethanol drinkers (author's transl)].

53 percent of ethanol drinkers had, before detoxication, a gamma-GT higher than the upper limit of the reference interval at the 2.5 percent risk level (36 mU/ml). 44 percent had a mean corpuscular volume (MCV) higher than the limit (99.2 mum3). In alcoholics not previously "weaned" during a rest cure or in a hospital the proportion becomes 67 percent for gamma-GT but remains at 44 percent for MCV. gamma-GT thus seems a better test for the screening of an excessive ethanol intake than MCV, especially when the subject has not been previously weaned.

[Decrease in serum gamma-glutamyltranspeptidase following abstention from alcohol in cirrhotics (author transl)].

Gamma-Glutamyltranspeptidase activity of patients having an ascitic cirrhosis due to ethanol consumption is high (139 mU/ml) when the patient is still drinking at the time of the assay; it is lower when the patient had stopped drinking at least two months before the assay (49 mU/ml). On the other hand, in 10 patients out of the 11 who submitted to a second assay gamma-glutamyltranspeptidase decreases as soon as the patient abstains from alcohol. In 4 abstinent patients re-examined one year after the first measurement, the gamma-glutamyltranspeptidase activity had decreased to the reference values of Szasz. The half time of the return to normal has been estimated by extrapolation from the ethylic model at between 11 and 54 days. We conclude that the hyper gamma-glutamyltranspeptidase in cirrhotics is due to the ethanol impregnation and that repeated assays of the enzyme show whether the patient abstains from alcohol or not.

[Use of the measurement of gamma-glutamyltranspeptidase activity in serum to determine the success of cures for alcohol detoxification (author's transl)].

44 patients were studied during a 2-year period following a cure for alcohol detoxification. 29 patients (group A) did not start drinking again while 15 relapsed less than one year after their cure (group R). The average gamma GT activity (m) in mU per ml serum was, in group A, 148 (standard deviation, S.D. 184) at the beginning of the cure, 21 (S.D. 14) after one year and 19 (S.D. 13) after 2 years. During the same period there was no significant decrease in group R (cure: m 140, S.D. 161: 1 year: m 166, S.D. 164; 2 years: m 162, S.D. 163). On the other hand, all the subjects of group A who had a high gamma GT activity (greater than 29 mU/ml) at the start of the cure showed a decrease after one year.

[Serum gamma-glutamyl-transpeptidase and alcoholism. Diagnosis and control of withdrawal].

The gammaGT of a generally healthy population is abnormally high due to the presence of ethanol in the diet. We confirm Rosalki's finding that a high proportion of alchoholics show an increased gammaGT activity. After alcohol deprivation, the gammaGT of alcoholics decreases in the first few days according to an exponential law with a half-time of return to normal of 5-17 days. Among past alcoholics, those who stopped drinking for a year have a lower GT activity (mean: 21 mU/ml) than a generally healthy population and in the range of Szasz's reference values. Alcoholics who did not stop drinking have a higher gammaGT activity (mean: 172). Ascitic cirrhotics who drink at least 1 liter of wine per day have also a high activity (mean: 139) while those who stopped drinking for at least 2 months have a much lower activity (mean: 49) and those who stopped for a year a normal activity. In 10 out of 11 alcoholic cirrhotics who stopped drinking, the gammaGT decreased (half-time: 11-54 days). These results show that the determination of gammaGT activity is a good test for the detection of ethanol impregnation.

[Detection of excessive chronic alcoholic consumption and control of withdrawal. Comparative study of respective values of the mean red-cell volume and serum gamma-glutamyl-transferase activity].

The routine detection of chronic alcoholism is necessary during any medical examination whether private or in hospital, or in occupational medicine. The practitionner now has available a simple reliable and cheap test. It consists of the serum estimation of gamma-glutamyl-transferase (gammaGT) and interpretation of the average red cell volume supplied by automatic counting of the red cell. Out of 120 chronic alcoholic subjects ; 67% has a gammaGT increased and 44% had macrocytosis. Under the influence of weaning, there was a rapid fall in gammaGT and a slower reduction in average red cell volume. gammaGT estimation was thus a more sensitive test than M.C.V. for the detection of chronic alcoholics and the control of withdrawal. Its association with the rise in immunoglobulin A-transferrin ratio which we have suggested permits the detection of almost all chronic alcoholics in the population studied.
