Background: Polymyalgia rheumatic is a syndrome that affects people over 50 years, characterized by pain and stiffness of shoulder and pelvic girdle. Its behavior in our population is unknown. It may be a manifestation of rheumatoid arthritis, systemic lupus erythematous, and neoplasm or could be associated with giant cells arteritis and it is a common indication for steroid usage. Objective: To analyze clinical, laboratory and treatment features of patients with PMR in Medellín between 1998-2011. Methodology: Descriptive cross-sectional study. We reviewed medical records of patients with PMR with at least 1 follow-up visit. We analyzed social, demographic, clinical, laboratory and therapeutic variables. Results: The records of 68 patients were assessed, 79.7% women. Pain and stiffness in shoulder and pelvic girdle were major symptoms. 62.3% had erythrocyte sedimentation rate equal to or greater than 40 mm/h and 81.2% had C reactive protein equal to or greater than 0.8 mg/dl. 76.9% received doses of prednisolone of 15 mg/day or below. 95.7% responded within the first 3 months of treatment, 94.2% showed remission (84.6% within the first 6 months), 39.1% relapsed (most within the first year of monitoring). Those with elevated ESR had a lower response in the first month. Five patients developed rheumatoid arthritis and two patients giant cells arteritis. Conclusions: These findings add more information about the clinical characteristics of patients with PMR. They allow suggesting early responses to treatment with low to moderate doses of steroids and a lower initial response in patients with elevated ESR. Design and sample size are insufficient to identify statistically significant associations.
