[Dysthymic disorders].

Long lasting, low intensity depressive episodes have been diversely integrated according to the classifications types or the psychodynamic points of view. The concept of anxious persistent lasting depression, neurotic depressive states, neurotic depression ... have been unified into the dysthymic disorder category of the DSM classification. This concept unification have been a topic of dispute considering that dysthymic disorder was a restrictive, heterogeneous an extensively comorbid diagnosis. Nevertheless the definition of this category offers the opportunity to place the notions of temperament, personality, adjustment disorder. Including dysthymic disorders as a category inside of the mood disorders classification suggests the interest of using an antidepressive medication in presence of chronic depressive states not included in the major depressive disorder category.

Initial monoamine oxidase-A inhibition by moclobemide does not predict the therapeutic response in patients with major depression. A double blind, randomized study.

It is generally accepted that the clinical efficacy of monoamine oxidase inhibitors (MAOI) is related to inhibition of this enzyme. In order to evaluate the predictive ability of monoamine oxidase-A inhibition for therapeutic efficacy, the start of treatment effects of moclobemide, a selective, reversible monoamine oxidase-A inhibitor, on plasma concentrations of monoamines and monoamine metabolites were determined. The plasma levels of 3,4-dihydroxyphenylglycol (DHPG, deaminated metabolite of noradrenaline), 5-hydroxyindoleacetic acid (5-HIAA, deaminated metabolite of serotonin), 3,4-dihydroxyphenylacetic acid and homovanillic acid (DOPAC and HVA, deaminated metabolites of dopamine), L-dihydroxyphenylalanine (L-dopa) and noradrenaline were investigated and related to treatment outcome. This was a randomized double blind parallel group study in 47 patients with criteria of major depression according to DSM III R. Moclobemide 300 mg/day, 450 mg/day or 600 mg/day was administered continuously for 6 weeks. Plasma concentrations of monoamine metabolites and monoamines were determined just before treatment by moclobemide, 4 h after the first dose, 24 h after the first dose, before the first dose on day 7, and 4 h after the first dose, on day 7. Each moclobemide dose improved depression as measured by MADRS (Montgomery-Asberg Depression Rating scale) but there was no difference between the three doses. Moclobemide dose-dependently reduced plasma concentration of DHPG, L-dopa and HVA. No dose-dependent treatment effect was observed for plasma 5-HIAA, noradrenaline and DOPAC. The clinical outcome as defined by the final MADRS score was not related to any start of treatment changes in plasma monoamine metabolites reflecting inhibition of MAO-A. It is concluded that monoamine oxidase-A inhibition at the beginning of the treatment does not predict clinical outcome.

[Effects of sulbutiamine (Arcalion 200) on psycho-behavioral inhibition in major depressive episodes].

UNLABELLED: Psycho-behavioural inhibition is characteristic of major depressive disorder and frequently recedes after the other depressive symptoms. This may induce an important psychosocial impairment which could be a risk factor for relapse. METHODS: The aim of this eight weeks, multicentric, randomized, double blind, placebo controlled trial was to assess the efficacy and safety of sulbutiamine (Arcalion) [600 mg p.d.] on the symptoms of psycho-behavioural inhibition of inpatients with DSM III-R defined Major Depressive Episode (MDE) treated by adjusted doses of clomipramine [75 to 150 mg pd]. Moderate doses of hypnotics and anxiolytics without potential activity on the mood were authorized during the trial. The MDE was assessed with the MADRS, HAM-A and CGI scales. Patients who did not respond adequately to the antidepressant treatment were prematurely withdrawn from the trial. The three Sheehan Disability Scales (SDS), the Norris Visual Analogue Scale (VAS) and the Depressive Psychomotor Retardation Scale (ERD) were used to monitor psycho-behavioural inhibition. RESULTS: The mean intake scores were, as expected, fairly high: MADRS (32), HAMA-A (23), CGI (5) and ERD (27). The SDS and EVA scores showed that the patients felt severely handicapped in their social, professional and family life functioning as well as in their emotional, affective, cognitive and behavioural performances. At four weeks the MADRS, HAM-A and CGI scores indicated that the global improvement of the MDE was comparable in both treatment groups. However, the scores at the EVA and SDS scales showed that the patients treated with sulbutiamine were significantly less incapacitated than the placebo group in all of the various facets (affective, cognitive, emotional, behavioural) of psycho-behavioural inhibition. Furthermore, the safety data shows that both treatment groups were comparable and in particular that sulbutiamine had not induced any inappropriate behaviour, including suicide attempts, or mania. CONCLUSIONS: Sulbutiamine has no antidepressive effect but it can hasten the resorption of psycho-behavioural inhibition occurring during major depressive disorder and thereby facilitate the rehabilitation of patients in their social, professional and family life functioning.
