Aspects épidémiologiquesPolyarthrite rhumatoïde (PR) Rheumatoid arthritis (RA) • Prévalence : 0.5% population caucasienne • Incidence : 40/100 000 habitants • Arthrite juvénile idiopathique • 15 ans et 3 mois : PR • Espérance de vie diminuée, morbidité CV +++ • Sex ratio : 4F/1H • Pic de fréquence : 40-50 ans • Étiologie multifactorielle
Aspects médico-économiques • 15% de formes graves • 50% arrêt activité prof. à 5 ans • 10% invalidité III en 2 ans • 25% temps aménagé • coûts directs : traitements, hospitalisations… • coûts indirects : arrêts travail, prestations sociales • coûts intangibles : douleur, anxiété, déformations, QDV
Economic Burden in Europe • In West Germany, RA costs were >DM 40 billion (US $17.6 billion) in 1994 for treatment alone • In the UK, average RA outpatient cost per case per year was £798 (US $1,126) and £1,253 (US $1,769) per inpatient in 1997 • Rheumatoid arthritis per capita costs average: • 49% of cost of cancer • 68% of cost of stroke • 82% of cost of coronary heart disease • 5 times the cost of motor vehicle accidents Knorr U.
