  • Résumé

    Effectiveness of paroxetine in the treatment of acute major depression in adults: a systematic re-examination of published and unpublished data from randomized trials

    Corrado Barbui MD, Toshiaki A. Furukawa MD, Andrea Cipriani MD

    From the Department of Medicine and Public Health, Section of Psychiatry and Clinical Psychology, World Health Organization Collaborating Centre for Research and Training in Mental Health (Barbui, Cipriani), University of Verona, Verona, Italy; and the Department of Psychiatry and Cognitive–Behavioral Medicine (Furukawa), Nagoya City University Graduate School of Medical Sciences, Mizuho-cho, Mizuho-ku, Nagoya, Japan

    Correspondance : Dr Corrado Barbui, Department of Medicine and Public Health, Section of Psychiatry and Clinical Psychology, University of Verona, Piazzale Scuro 10, 37134 Verona, Italy; fax +39-045-585871 (for the World Health Organization Collaborating Centre for Research and Training in Mental Health); corrado.barbui{at}univr.it

    Contexte : On a soulevé des préoccupations au sujet de l’efficacité de la thérapie aux antidépresseurs contre la dépression majeure chez les adultes. Nous avons entrepris une revue systématique de données d’études cliniques publiées et non publiées afin de déterminer l’efficacité et l’acceptabilité de la paroxétine.

    Méthodes : Nous avons effectué une recherche dans le Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Register, le Cochrane Central Register of Controlled Trials, le GlaxoSmithKline Clinical Trial Register, MEDLINE et EMBASE jusqu’en décembre 2006. Les études randomisées publiées et non publiées au cours desquelles on a comparé la paroxétine à un placebo chez les adultes atteints d’une dépression majeure pouvaient être inclus. Nous avons choisi le pourcentage des patients qui ont quitté l’étude avant la fin pour n’importe quelle raison comme la principale mesure des résultats, parce que cette donnée représentait une mesure concrète de l’efficacité et de l’acceptabilité du traitement.

    Résultat : Nous avons inclus dans notre revue 29 études cliniques publiées et 11 non publiées portant au total sur 3704 patients qui ont reçu de la paroxétine et 2687 qui ont reçu le placebo. Il n’y avait aucune différence entre la paroxétine et le placebo sur le plan du pourcentage des patients qui ont quitté l’étude avant la fin pour quelque raison que ce soit (risque relatif RR d’effet aléatoire, 0,99, % intervalle de confiance IC à 99 % 0,88–1,11). La paroxétine était plus efficace que le placebo, le groupe recevant le médicament comptant moins de patients qui n’ont pas vu leurs symptômes s’améliorer d’au moins 50 % (RR d’effet aléatoire, 0,83, IC à 99 %, 0,77–0,90). Beaucoup plus de patients qui ont pris de la paroxétine que de patients qui ont pris le placebo ont quitté leur étude respective à cause des effets secondaires (RR d’effets aléatoires 1,77, IC à 95 %, 1,44–2,18) ou ont eu des tendances suicidaires (coefficient de probabilité 2,55, IC à 95 %, 1,17–5,54).

    Interprétation : Chez les adultes aux prises avec une dépression majeure de modérée à sévère et visés par les études cliniques que nous avons revues, la paroxétine n’était pas supérieure au placebo sur le plan de l’efficacité et de l’acceptabilité globale du traitement. L’inclusion sélective d’études publiées n’a pas biaisé ces résultats.
