Brief summary
Use of genotyping for the optimization of treatment with biologics in chronic arthritis by looking for an association between certain alleles and response to treatment.
Detailed description
Chronic arthritis in children and in adults represent a public health problem in number and difficulty of treatment. 30% of patients are non-responders and / or relapse upon discontinuation of treatment. Some of these treatments are not always well tolerated, sometimes with infectious complications including tuberculosis limiting the use of biological therapies. This study will validate a battery of genetic markers to predict responders biotherapy, determine the prognosis of patients, these treatments are reserved for the most severe forms, and thus improve the care of patients.
