Résumé
Les auteurs rapportent deux observations d’entérite ulcéreuse à la Clofazimine caractérisée par des lésions érosives à prédominance iléale.
La Clofazimine — dérivé du tartrate de phendimetrazine — utilisée dans le traitement de la lèpre, du pyoderma gangrenosum et du lupus erythémateux chronique, provoque des lésions œdémateuses et ulcéreuses aphtoïdes du grêle, lentement régressives après arrêt du médicament.
Le diagnostic des lésions reste radiologique, mais l’entéroscopie dans un cas a permis leur mise en évidence au niveau jéjunal. L’histologie n’est pas spécifique. Des lésions d’entérite à eosinophiles et des dépôts de cristaux de Clofazimine dans les ganglions mésentériques et la paroi intestinale ont été mis en évidence lors d’autopsies de sujets décédés de la lèpre.
Summary
The authors report two cases of ulcerative enteritis related to clofazimine characterised by erosive lesions predominantly in the ileum.
Clofazimine, a derivative of phendimetrazine tartrate used in the treatment of leprosy, pyoderma gangrenosum and chronic lupus erythematosus, causes oedematous, ulcerative, aphtoid lesions of the small intestine which slowly regress once the medication is stopped.
The diagnosis of the lesions is primarily radiological, although, in one case, enteroscopy was able to reveal such lesions in the jejunum. The histology is nonspecific. Autopsies of subjects who died from leprosy revealed eosinophilic enteritis lesions and Clofazimine crystal deposits in the mesenteric lymph nodes and in the walls of the intestine.
