We studied platelet 3H-serotonin uptake in 32 former alcoholics, withdrawn for from 1 month to 22 years, in their descendants (21.7 +/- 1.6 years old, n = 17; 10.9 +/- 0.7 years old; n = 19), and in respective control groups, paired in age and sex. All of the alcoholics presented high 3H-serotonin uptake (Vmax = 10.88 +/- 4.23 pmoles/10(8)pl/30 sec., vs. 0.93 +/- 0.15 pmole/10(8)pl/30 sec. Their descendants also showed high platelet serotonin uptake: 3.94 +/- 1.44 pmoles/10(8)pl/30 sec., vs. 0.93 +/- 0.15 pmoles/10(8)pl/30 sec. for adult descendants, and 5.99 +/- 2.23 vs. 0.84 +/- 0.15 pmole/10(8)pl/30 sec. for young descendants. All subjects were free of alcoholisation (biological parameters studied were blood ethanol concentration, gamma glutamyl transferase and mean corpuscular volume), and dependence of former alcoholics was evaluate by using, a posteriori, the CAGE test. In descendants, 28% of the subjects have Vmax values higher than the highest of the control group. Alcohol, in vitro, (54 mM) did not affect serotonin uptake in any group. These results indicate that in descendants of alcoholics, platelet serotonin uptake is altered, without modification of sensitivity to ethanol. The genetic basis of alcohol dependence could be linked with the platelet serotonin transport.

We present a study of 107 in-patients of a detoxification center. As expected, 81 percent of them showed upon admittance an increased serum gamma glutamyl transferase (GGT). After alcohol withdrawal, GGT decreased in all but one of these patients. More surprisingly, even among the rest of the patients exhibiting upon admittance a GGT result within the reference range, there still occurred a significant decrease in 50 percent of the cases. Thus, whether the initial GGT is high or normal, we observed a decrease in 96 patients out of 107, i.e., a sensitivity of 0.90. The decrease test consists in asking a subject to refrain from any alcohol intake during a short period, e.g., seven days. If any significant diminution of serum GGT occurs, the possibility of alcohol abuse should at least be given serious consideration before being rejected. This test was used up to now only when GGT was initially high. The present results show that it can be attempted even when GGT is initially within the normal range, with a sensitivity of 0.90.

129 chronic alcoholic patients, withdrawn from alcohol and presenting major depression or dysthymic disorder, were treated for 4-8 weeks under double-blind conditions either with a new antidepressant, tianeptine (37.5 mg per day), or with amitriptyline (75 mg per day). Both groups presented steady improvement of the symptoms of depression during treatment, as scored on the Montgomery and Asberg Depression Rating Scale and the Hopkins Symptom Checklist self-evaluation; for the latter scale, the improvement was significantly greater in the tianeptine group. In addition to the improvement of mood, tianeptine also produced significant reduction of the somatic complaints of the depressed patients. Furthermore, tianeptine possesses anxiolytic activity, as shown by the change of the Hamilton Anxiety Rating Scale global score, similar to that produced by amitriptyline. The anxiolytic activity of tianeptine was not accompanied by any impairment of vigilance, unlike that of amitriptyline. Tianeptine produced rare, mild anticholinergic effects. The results obtained show that tianeptine is an effective anxiolytic antidepressant, with better safety than amitriptyline, suitable for use in the treatment of mood disorders following alcohol withdrawal.
