摘要: Resume Les anticorps antiproteines ribosomales P (anti-P) sont diriges contre trois phosphoproteines nommees POP1 et P2 consideres comme des marqueurs specifiques du lupus erythemateux systemique (LES) plus particulierement atteintes neuropsychiatriques de cette maladie. Notre etude a eu pour but determiner la frequence anti-P chez patients tunisiens atteints LES d’analyser leur signification clinique. Methodes. Cent dont les serums ont ete recus janvier 1998 decembre 2000 au laboratoire d’immunologie l’hopital Charles Nicolle Tunis qui testes recherche d’anticorps anti-P. La detection faite par une technique d’immunodot utilisant un peptide synthetique commun aux phosphophoproteines ribosomales. Resultats. Vingt-deux presentaient dans serum (22 %). Cette est comparable donnees litterature. L’analyse renseignements cliniques notre serie n’a pas etabli d’association statistiquement significative avec particulieres LES. Conclusion. montre association autoanticorps anti-Sm anti-RNP, deja decrite litterature sujette discussion.
