Objectives: To assess health-related quality of life (HRQoL) in patients with rheumatoid arthritis (RA) treated with etanercept or adalimumab in routine clinical practice.
Methods: Patients with RA who started etanercept or adalimumab at Helsinki University Central Hospital or Lappeenranta Central Hospital during 2003-2006 were asked to participate in the study. In 97 patients, HRQoL was measured by the RAND 36-Item Health Survey 1.0 (RAND-36) at baseline and after three months of the treatment. HRQoL of the RA patients was compared to the Finnish age- and sex-matched general population values. In addition, changes in clinical parameters and disability index measured by the health assessment questionnaire (HAQ) were recorded.
Results: Treatment with etanercept and adalimumab increased the values in all domains of the RAND-36 during the first three months in routine practice. The improvement in both groups was statistically significant: with etanercept p=0.041 and with adalimumab p=0.019. The efficacy of etanercept and adalimumab in improving HRQoL during the first three months was comparable. The patients reported their best improvement in the subscales of bodily pain, role functioning/physical, energy, social functioning, and role functioning/emotional. Compared to the Finnish age- and sex-matched general population values, the HRQoL of the patients with RA was significantly lower at baseline and remained low at follow-up. The change in clinical parameters and the HAQ paralleled the improvement in HRQoL.
Conclusion: Treatment of patients with RA with etanercept and adalimumab in routine clinical practice provides clinically important and statistically significant improvement in HRQoL already in the first three months.
