Absent cardiac and muscle sympathetic nerve activities involvement in Ross syndrome: A follow-up study.

Abstract

Ross syndrome (RS) is characterized by selective involvement of post-ganglionic skin sympathetic nerve fibres. We report a follow-up study in 4 patients to clarify whether in RS autonomic dysfunction spreads affecting also cardiovascular system. The patients underwent cardiovascular reflexes (CVR) and microneurography recording of muscle sympathetic nerve activity (MSNA) for a follow-up mean period of 5years. CVR and MSNA were normal at baseline and unchanged over the follow-up. Cardiovascular autonomic system is spared in RS differently from skin autonomic activity dysfunction which progress over time. However, before drawing any definite conclusion, a large cohort of patients needs to be studied.
