Objective
The aim of this study was to evaluate the safety and effectiveness of a supervised walking program in women with primary Sjögren’s syndrome (pSS).
Methods
Forty-five sedentary women fulfilling the American European Consensus Criteria for pSS were randomized to a training group (TG, n = 23) or control group (CG, n = 22). Patients in the TG were submitted to supervise walking three times a week for 16 weeks. The patients of the CG were instructed to not perform any kind of regular physical exercise. Physical fitness [maximum oxygen uptake (VO2max) and distance], EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI), hematological tests, and Medical Outcomes Study 36 (SF-36) were assessed at baseline and week 16. In addition, EULAR Sjögren’s Syndrome Patient Reported Index (ESSPRI), Functional Assessment of Chronic Illness Therapy Fatigue Subscale (FACIT-fatigue), and Beck Depression Inventory (BDI) were measured prior to intervention, after 8 and 16 weeks. Patient global assessment of response to therapy was completed at the final assessment. An intent-to-treat analysis was performed.
Results
After 16 weeks, the mean change of VO2max (ml/kg/min), distance, and FACIT-fatigue were higher in the TG than in the CG (p = 0.016, p = 0.043 and p = 0.030, respectively). Improved cardiorespiratory fitness was associated with improvements in fatigue scores and physical components of quality of life (SF-36). Furthermore, improved fatigue scores were associated with reduced depression and improvements in the physical and mental components of SF-36. Overall, 95.4% of patients in the TG rated themselves as clinically improved versus 62% of the patients in the CG (p = 0.049). There was no flare in disease activity and no serious adverse events with exercise.
Conclusions
This supervised walking program was demonstrated to be feasible and safe with improvements in cardiorespiratory fitness, exercise tolerance, fatigue, and patient perception of improvement in pSS patients.
