Small fiber neuropathy and related factors in patients with systemic lupus erythematosus; the results of cutaneous silent period and skin biopsy.

Introduction: Evaluating small nerve fibers in patients with systemic lupus erythematosus (SLE) using cutaneous silent period (CSP) and skin biopsy and assesssing the relationship between clinical signs, autoantibodies and neuropathic pain score.

Objective - Methods: Fifty one SLE patients and 46 healthy volunteers were included in this study. Nerve conduction studies and CSP were performed both on upper and lower limbs in subjects.

R-R interval variation and sympathetic skin response in systemic lupus erythematosus.

The involvement of the autonomic nervous system is less common than that of the central and peripheral nervous system in systemic lupus erythematosus (SLE) patients. However, its involvement can negatively affect the quality of life of the patient and cause life-threatening situations. In this study, autonomic function was evaluated in SLE patients who did not show any sign of autonomic involvement using R-R interval variation (RRIV) and sympathetic skin response (SSR) electrophysiological tests.
