Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the effect of supervised physical exercise on endothelial function and number of endothelial progenitor cells (EPCs) in patients with systemic lupus erythematosus, as well as evaluate the effect of supervised physical exercise on endothelium derived growth factor (VEGF) levels, disease activity, quality of life, fatigue, perceived exertion and cardiopulmonary exercise test variables.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Several studies have shown that cardiovascular morbimortality is more frequent and early in SLE patients than in the general population and cardiovascular disease is an important cause of morbidity and mortality in systemic lupus erythematosus patients. Disturbances in endothelial function are implicated in its pathogenesis. Endothelial function also depends on endothelial progenitor cells (EPCs) that enhance angiogenesis, promote vascular repair and have potential as a marker of cardiovascular disease. Systemic lupus erythematosus patients have endothelial dysfunction and fewer EPCs. There are studies showing improvement of endothelial function and EPCs after physical exercise program in individuals with heart failure, diabetes and coronary arterial disease, but there isn't studies evaluating endothelial function and EPCs after.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Supervised physical exercise

Walking at speed of the ventilatory threshold-1 heart rate obtained from cardiopulmonary exercise test and monitored by frequency meter.

Group Type EXPERIMENTAL

Supervised physical exercise

Intervention Type BEHAVIORAL

Women with systemic lupus erythematosus with availability to perform physical exercise were allocated in exercise group (EG) to practice supervised physical exercise for one hour, three times a week for 16 weeks. Those who were not available for this activity were allocated in the control group (CG). Intervention consisted of walking at speed of the ventilatory threshold-1 heart rate obtained from cardiopulmonary exercise test and monitored by frequency meter.

No supervised physical exercise

No intervention for 16 weeks
