Long-term outcome among patients with juvenile rheumatoid arthritis.

Juvenile rheumatoid arthritis (JRA) is a chronic inflammatory disease primarily affecting the joints but also extra articular tissue. The long-term outcome of JRA has different aspects, which include disease outcome, mortality, iridocyclitis and stature. Several studies, which have addressed these issues, are reviewed in this article. In addition, functional, educational and employment status of patients with JRA are also reviewed. To facilitate better understanding of these various studies, a description of the terminology used in defining disease is provided. Several of the instruments that are available for assessing outcome among patients are described. The role of laboratory and radiological evaluation in predicting outcome is also addressed.
