Modulation of sphingosine receptors influences circadian pattern of cardiac autonomic regulation.

ABSTRACT: Fingolimod is an oral sphingosine-1-phospate (S1P) receptor modulator for the treatment of relapsing-remitting multiple sclerosis (RRMS). In addition to therapeutic effects on lymphoid and neural tissue, fingolimod influences cardiovascular system by specific S1P-receptor modulation. The effects of S1P-receptor modulation on the endogenous circadian pattern of cardiac autonomic regulation (CAR), however, are not known. We examined the effects of fingolimod on the circadian pattern of CAR Ambulatory 24-h ECG recordings were undertaken in 27 RRMS patients before fingolimod (baseline), at the day of fingolimod initiation (1D) and after 3 months of fingolimod treatment (3M). The mean time between two consecutive R-peaks (RR-interval) and mean values for measures of heart rate variability (HRV)
