Progressive multiple sclerosis patients have a higher burden of autonomic dysfunction compared to relapsing remitting phenotype
OBJECTIVE: To determine autonomic dysfunction (AD) differences in patients with relapsing remitting multiple sclerosis (pwRRMS) and progressive MS (pwPMS). METHODS: Composite autonomic scoring scale (CASS) and heart rate variability (HRV) were performed in 40 pwRRMS and 30 pwPMS. RESULTS: pwPMS had a significantly higher sudomotor index and total CASS score compared to pwRRMS (p < 0.001 and p < 0.001, respectively). Disease duration positively correlated with sudomotor index and total CASS (rs = 0.409, p < 0.001 and rs = 0.472, p < 0.001, respectively), while the Expanded Disability Status Scale (EDSS) positively correlated with sudomotor index and total CASS (rs = 0.411, p < 0.001 and rs = 0.402, p = 0.001, respectively) in all patients. Type of multiple sclerosis (pwRRMS or pwPMS) corrected for age, sex and disease duration, was a statistically significant predictor of CASS value (B = 1.215, p = 0.019). Compared to pwRRMS, pwPMS had a significantly lower standard deviation of NN intervals (SDNN), low frequency (LF), and high frequency (HF), during both the supine and tilt- up phases (all p-values <0.006). pwPMS had a significantly lower LF/HF (p = 0.008) during tilt- up. CONCLUSION: There is a significant difference in autonomic function in pwRRMS and pwPMS ; with pwPMS having a higher burden of AD, which is particularly evident for sweating dysfunction. SIGNIFICANCE: Further research is needed to establish whether parasympathetic and sudomotor dysfunction may serve as markers of progressive MS.
