Cardiovascular Autonomic Neuropathy in Systemic Lupus Erythematosus.

چکیده
PURPOSE Objective is to evaluate cardiovascular autonomic function in SLE by simple non-invasive tests. METHODS A case control study was carried out involving 18-50 yrs old previously diagnosed SLE patients and same number of age and sex-matched controls. Parasympathetic function was assessed by heart rate (HR) response to Valsalva maneuver, deep breathing and standing. Sympathetic function was evaluated by blood pressure response to standing and sustained hand-grip test (HGT). RESULTS There were 50 female SLE patients. They had significantly higher minimum resting HR and diastolic blood pressure (DBP). HR variation with deep breathing, expiratory inspiratory ratio, 30:15 ratio and DBP change in response to HGT were significantly lower inpatients compared to controls. Thirty patients (60%) had at least one abnormal or two borderline test results indicating autonomic impairment of which 27 had parasympathetic dysfunction and 7 had sympathetic dysfunction. CONCLUSION Autonomic dysfunction is common in SLE with higher prevalence of parasympathetic impairment.

In chronic inflammatory diseases, cytokines stimulate the hypothalamus–pituitary–adrenal axis and the hypothalamus– autonomic nervous system (HANS) axis. The present study was performed to find autonomic nervous function parameters in patients with systemic lupus erythematosus (SLE) which are suitable to demonstrate the activation of the HANS axis during systemic inflammation. Thirty-four patie...
