Anti-inflammatory properties of Risperidone : A clinical Trial

Résumé

Introduction The evidence of an inflammatory status at onset of psychosis supports the adjunction of anti-inflammatory agent to antipsychotic (AP). Some negative results of these clinical trials lead us to wonder about the anti-inflammatory power of AP. Objectives Would the action of associated anti-inflammatory agents be negligible compared to the anti-inflammatory potential of AP? Methods We conducted a prospective study. We included patients hospitalized for acute relapse of schizophrenia. They were all treated with Risperidone. We measured High sensitive C Reactive Protein (Hs CRP) at baseline and 8 weeks after. Results We included 24 patients. Mean age was 34,5 +7,32 years with 75% of female. Mean age of onset of illness was 24,63 ±4,81 years and illness duration was 10,70 +6,42 years. After 8 weeks, PANSS scores decreased significantly from 79,13 +12,07 to 47,21 +8,41 and Hs CRP levels dropped by 1,55 +3,96 mg/l. Conclusions These results highlighted the anti-inflammatory action of Risperidone. Clinical trial should consider the proportion of anti-inflammatory agents action.
