À propos d’une cohorte de jeunes patients suivis dans le service de rhumatologie adulte du CHU de Liège. : About a pediatric patients cohort followed in the adult rheumatology department of CHU Liège.

We realized an observational retrospective study about pediatric patients (between 1 to 18 years) followed at the CHU Liège in an adult rheumatologic service during the last 14 years. This study identified 102 patients who developed the first symptoms during infancy, identifying 39 different diseases. Mainly, we identify cases of idiopathic juvenile arthritis, rheumatoid arthritis, spondylarthropathies, systemic lupus erythematosus, systemic vasculitis, connective tissue diseases, bone diseases, and phosphocalcic metabolic disorders. These observations highlight the difficulties to classify inflammatory articular diseases in young patients. Furthermore, this article may be helpful to identify some specificities in the pediatric population who suffers from rheumatologic diseases and some essential factors to make an optimal transition to adult medicine.
