A pilot study on the effects of exercise in patients with systemic lupus erythematosus

Objective. A pilot study was designed to assess the efficacy and safety of different exercise therapies on patient-reported fatigue and functional sta tus. Methods. Ten patients with systemic lupus erythematosus (SLE) were randomly placed in either an aerobic exercise group (group 1 : n = 5) or a range of motion/muscle strengthening (ROM/MS) exercise group (group 2 : n = 5). Out come measures assessed at baseline and the end of the study were fatigue, f unctional status, disease activity, cardiovascular fitness, isometric stren gth, bone mineral density (BMD) of the lumbar spine and femoral neck, and p arathyroid hormone and osteocalcin as representative bone biochemical marke rs for bone resorption and bone formation, respectively. Results. Both aerobic and ROM/MS types of exercise were safe and did not wo rsen SLE disease activity. Patients in both exercise groups showed some imp rovement in fatigue, functional status, cardiovascular fitness, and muscle strength. Both groups showed increased bone turnover, but BMD was unchanged . Eighty percent of the patients met the compliance standard for the study. Conclusions. This pilot study shows the feasibility of exercise for SLE pat ients. The potential value of this approach shows promise in the routine ma nagement of these patients.
