NoSPeR is a study group currently working on Nordic population-based follow-up study on juvenile idiopathic arthritis (JIA).
The participating countries are Denmark, Finland, Norway, and Sweden.
The patients were enrolled between the years1997-2000.
The main targets of the study were to achieve more information about the epidemiology, outcome and disease characteristics of JIA.
At first the study was planned for 8 years’ period focusing mainly on disease activity and possible damages related to it. Later it was prolonged until 15-year follow-up which has just started.
Clinical risk factors and biomarkers of JIA-associated uveitis have also been studied.
The study has already resulted in several publications in central international journals of rheumatology.
