RESULTS
In total, all 390 patients from the three countries Argentina (n=236), Colombia (n=85) and México (n=69) participating in the ASAS-COMOSPA-study were included in the analysis. Patient characteristics including demographic and disease characteristics by country, for the LA countries combined and the global study population -which includes information for the LA countries- are presented in table-1. In the LA countries, sixty-four percent were male, with a mean age of 45 (15) years and a mean disease duration since symptom onset of 7.0 (8.1) years. The proportion of patients with arthritis, enthesitis and dactylitis was higher in the three LA countries (74%, 62% and 24%, respectively) as compared with all patients (n=3,984) in the ASAS-COMOSPA-study (56%, 38% and 16%, respectively). The usage of NSAIDS and DMARDS (particularly methotrexate) was higher in LA countries than in the entire ASAS-COMOSPA-study (72% and 48% respectively for NSAIDS, and 68% and 33% respectively for DMARDS), whereas biological therapy was less frequently used (34% vs 44% respectively). The most common comorbidities and risk factors in all three LA countries were: AHT (25.3%)(95%CI 21.2 to 30.0), hypercholesterolemia (21.5%)(95%CI 17.6 to 26.0), osteoporosis (9.4%)(95%CI 6.8 to 12.9) and gastrointestinal ulcer (7.7%)(95%CI 5.3 to 10.9).
