Abstract

Background Greater knowledge of the behavior of rheumatoid arthritis in his response to biological therapy and the need to improve the resource efficiency of national health systems has led in recent years to implement optimization strategies with the treatments most overburdened financially to social security systems.

Objectives The aim of this study is to describe what the status of such optimization and clinical conditions that takes place in a hospital serving the healthcare demands of nearly one million inhabitants.

Methods All patients with a diagnosis of RA (ACR/EULAR 2010), served in the Clinical Management HUVR in Seville, during the period January 2008 to May 2014 and received at least one dose of etanercept with indication sheet in Spain.

Design: Observational, longitudinal, retrospective and analytical study.

Patients and methods: Five rheumatologists, after defining the project and the variables to obtain reviewed the medical records of patients and collected them in a database designed exprofeso sociodemographic variables, RA and clinics. As part of clinical management, to achieve remission defined as =1 =1 and swollen joint painful joint sustained for at least two consecutive visits, was decided to reduce the biological dose.

Statistical analysis: descriptive, univariate tests according to the distribution of variables an

Results Results: 130 patients were included, excluded 4 (3%) by incomplete data for analysis. The median age (p25-p75) of the 126 (97%) patients was 55.9 (47-65), 79% female, 72% FR +, 49% received etanercept as first biological and the rest as second or third 44% were treated with concomitant MTX and 28% with low doses of corticosteroids. The duration of RA was 10.9 (6.9 to 20) years. Remission was found and it was possible to reduce the dose of etanercept in 92 (73%) cases. Of these, only 1 (0.8) discontinued treatment due to persistence of remission and the majority (48%) received doses of 25 mg of etanercept every 7 days. The main characteristics of the two groups of patients are shown in the table. In multivariate analysis that shorter duration of RA greater chance of remission (OR 0.98 95% CI 0.97 to 1.001) and smoking as a factor of no remission (OR 2.54 95% CI 1,1 5 found, 8), but the predictive capabilities of the models were low (11%).

Conclusion: In patients with RA treated in routine clinical practice and appropriate response to etanercept, remission is possible and reduces the dose of biological two-thirds of patients with RA, although the definitive discontinuation is rare.
