To describe the occurrence and main clinical and laboratory findings of patients having both juvenile idiopathic arthritis (JIA) and diabetes mellitus type 1 (DM-1) in a period of 30 years. Methods. Eighty-two patients having simultaneous JIA and DM-1 were identified in the reimbursement registers of the Finnish National Institute of Insurance during the period 1976{\textendash}2005. Data on their clinical histories were collected from patient files. Results. Occurrence of simultaneous JIA and DM-1 increased 4.5-fold between the first (1976-85) and the last (1996{\textendash}2005) decade. Prevalence of uveitis was 7\%, of rheumatoid factor seropositivity 15\%; 22\% of patients had a third autoimmune disease [autoimmune disease (AID)], and 16\% had serious psychiatric problems. Conclusion. The occurrence of patients with the 2 diseases, JIA and DM-1, increased over 3 decades. The prevalence of uveitis was low, the number of seropositive patients was high, and further cases of AID were frequent. Patients had multiple additional problems necessitating multiprofessional care.}, issn = {0315-162X}, URL = {https://www.jrheum.org/content/39/2/377}, eprint = {https://www.jrheum.org/content/39/2/377.full.pdf}, journal = {The Journal of Rheumatology} }
