High‐dose chemotherapy (HDC) followed by autologous hematopoietic stem cell transplantation (HSCT) is a new treatment for patients with severe, refractory rheumatoid arthritis (RA). The present study was undertaken to assess the health status of patients with severe RA over a long‐term followup period after treatment with HDC + HSCT.Health status and utility scores were assessed in 8 patients before and after treatment with HDC + HSCT. Patients were followed up for 5 years posttransplantation. Health status was assessed by the Health Assessment Questionnaire (HAQ), the RAND‐36 version of the Short Form 36 (SF‐36) health survey, and the Arthritis Impact Measurement Scales (AIMS). Utility scores were calculated using the EuroQol (EQ‐5D) questionnaire and the SF‐36–derived utility index (called the SF‐6D), from which quality‐adjusted life years (QALYs) were derived. Most measures of health status improved compared with baseline in the first 2 years posttransplantation, notably HAQ and AIMS scores and scores on the functional status, general health, and health change summary scales of the RAND‐36 version of the SF‐36. Utility scores derived from the EQ‐5D questionnaire and the SF‐6D also increased significantly after transplantation. This was reflected in the 0.28 QALYs gained compared with baseline. For a putative 50‐year‐old RA patient with a life expectancy of 20 years, a threshold analysis revealed that HDC + HSCT yielded more QALYs than conventional therapy when treatment‐related mortality (TRM) was <2.8%.HDC + HSCT temporarily increased the functionality and health status of patients with severe, refractory RA. With a reported TRM of 1.3%, HDC + HSCT can be considered a realistic treatment option for patients with severe RA. [ABSTRACT FROM AUTHOR]
