[Social adjustment and depression: value of the SAS-SR (Social Adjustment Scale Self-Report)].

The Social Adjustment Scale Self-Report (SAS-SR) is a simple and inexpensive method, which allows the routine assessment of the patient's social adjustment, especially in the case of depression. Compared with other scales based on an interview with the patient, the SAS-SR is more sensitive to change in the patient's clinical status. The SAS-SR is a useful method as part of the detection of even mild depressions, regular aftercare evaluation of out-patients or as an outcome measure in longitudinal studies. A French version of the SAS-SR is now available and is currently under evaluation in a large-scale randomized therapeutic trial.

[The role of type 2 serotonin receptors, 5-HT2A and 5-HT2C, in depressive disorders: effect of medifoxamine].

The serotonin (5-HT) is implicated in many centrally-regulated functions and has shown to be involved in affective disorders, such as depression and anxiety disorders. Recent progress in pharmacology and molecular neurobiology have confirmed the concept of the heterogeneity of 5-HT receptors and permitted reformulation of new hypothesis concerning antidepressant mechanisms of action, in particular those concerning serotoninergic receptors. Up to date, among the 5-HT defined sites, only 13 have been cloned, and several subfamilies have been described. Particularly, the 5-HT1 family containing receptors: 5-HT1A, 5-HT1B/1D, 5-HT1E and 5-HT1F. The 5-HT2 family includes receptors that stimulate phospholipase C: 5-HT2A (previously termed 5-HT2), 5-HT2B and 5-HT2C (previously termed 5-HT1C). Concerning 5-HT2 family, it is possible that some 5-HT binding drugs properties initially attributed to 5-HT2A receptors, might well be mediated by 5-HT2C receptors. Recently, medifoxamine (Cledial) activities on 5-HT systems have been shown. In particular, these activities are related on 5-HT2C and/or 5-HT2A binding sites. Results indicate that, in vitro, medifoxamine affinities (Ki) are near to 1 microM, for both 5-HT2C and 5-HT2A sites (ratio = 1.42). On the other hand, m-CPP, an 5-HT2C agonist, considered as a reference compound, has the same affinities that medifoxamine, but a higher one for 5-HT2A (ratio = 3.42). In animals models considered as predictive for psychotropic activity in human, we investigate in rat the impact of medifoxamine on 5-HT2C receptors, using Learned-Helplessness model (LH) and the social interaction test.(ABSTRACT TRUNCATED AT 250 WORDS)

[Randomized double-blind comparative study of the efficacy and tolerance of medifoxamine and imipramine in depressed patients].

Medifoxamine (Clédial TM), a non tricyclic non MAOI antidepressant drug with a dopaminergic and serotoninergic mechanism of action, was compared to imipramine in a multicenter double blind trial. Patients suffering from DSM III-R major depression (without psychotic features), with a minimum inclusion score of 25 at the MADRS after an initial 7-day wash-out period, were randomly assigned to a 4-week treatment by either imipramine or medifoxamine, with flexible doses of at least 100 mg after 2 weeks of treatment. No associated treatment was permitted except for lorazepam 2 to 5 mg per day. Ninety eight patients were recruited by 20 centers throughout France. Eighty four terminated the 4-week protocol. Early terminations were due to serious adverse events (3), death on imipramine (1), protocol violation (1), refusal to continue (1), loss to follow up (1). The 2 groups of patients were comparable on inclusion. In the medifoxamine group (receiving a daily dose of 194 mg at day 28) the percentage of improvement in MADRS scores, the number of patients with a MADRS improvement of a least 50% and a final MADRS score inferior to 8, were not significantly different from the imipramine group (daily dose: 161 mg at day 28). No more difference appeared when several clinical variables were analyzed, in particular the DSM III-R melancholic, the Newcastle endogenous subtypes and the in or out patient status. The two treatment groups were also comparable on other scales (HDRS, HARS assessing anxiety, CGI).(ABSTRACT TRUNCATED AT 250 WORDS)
