Introduction The prevalence of undifferentiated inflammatory joint disease in cohorts of recent onset arthritis is variable (23%–56%). It has been observed that 54% goes into remission spontaneously 30% evolves to rheumatoid arthritis or other defined inflammatory joint disease and 20% continúes under the diagnosis of undifferentiated arthritis. Objective Describe the clinical characteristics and the behavior over time of patients with undifferentiated arthritis from two centers of rheumatology, Medellín, Colombia. Materials and methods Descriptive cross sectional study. We reviewed medical records of patients with diagnosis of undifferentiated arthritis followed for ≥ 6 months in Reumatologya S.A. and Clínica Las Vegas. Demographic, clinical and laboratory variables were analyzed. Results Sixty one medical records included. The involvement was monoarticular in 36.1%, oligoarticular in 27.9% and polyarticular in 36.1%. In 75.4%adefinite inflammatory joint disease was established (26.2% rheumatoid arthritis, 16.4% calcium pyrophosphate arthropathy, 6.6% monosodium urate crystals arthropathy, 6.6% seronegative spondyloarthropathy 4.9% erosive osteoarthritis and 14.5% others). Conclusions During follow-up, 24.6% of patients continued havinga diagnosis of undifferentiated arthritis. Arthritis was self-limited in a 6.6% of patients and in a 75.4% a definite inflammatory joint disease was established. Although the design and study sample size are insufficient to identify statistically significant associations, these findings contribute to understand the behavior of undifferentiated arthritis in Colombia. © 2012 Asociación Colombiana de Reumatología
