Abstract
- Objective To compare the relative effectiveness of anti–tumor necrosis factor (anti-TNF) therapies on health-related quality of life (HRQOL) by inflammatory arthritis types. Methods Patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA) who had anti-TNF therapy (etanercept, adalimumab, or infliximab) in the Australian Rheumatology Association Database during 2001–2011 were assessed using the Medical Outcomes Study Short Form 36 (SF-36), Assessment of Quality of Life (AQoL), and Health Assessment Questionnaire (HAQ) disability index (DI) on a biannual basis. Linear regression was used for the analysis; the lack of independence in outcomes for multiple assessments in the same patient was taken into account using generalized estimating equations. Results There were 18,119 assessments (first-time drug use n = 12,274, subsequent use n = 3,098, and no use n = 2,747) provided by 3,033 patients (2,240 RA, 507 AS, and 286 PsA patients) with the anti-TNF therapies. The effects of subsequent use versus first-time use were reduced on the SF-36 physical component summary, AQoL, and HAQ DI scores among RA patients. After adjusting for therapy order, calendar year, sex, age, smoking status, and various medication uses, the 3 anti-TNF preparations had similar effects on the HRQOL measures for patients with RA, AS, or PsA. However, differences between anti-TNF therapies were observed in the AQoL score among PsA patients (infliximab versus etanercept: −0.06 [95% confidence interval (95% CI) −0.12, −0.004]) and in the SF-36 mental component summary score among RA patients (adalimumab versus etanercept: −1.17 [95% CI −1.88, −0.46]). Conclusion This study revealed similar effectiveness of etanercept, adalimumab, and infliximab on the HRQOL measures among Australians with RA, AS, and PsA.
