Characterizing sweating problems in multiple sclerosis: insights from QSART, SUDOSCAN, and COMPASS-31 : Sweating Problems in Multiple Sclerosis - 05/12/25
Highlights |
• | Symptomatic sweating disturbance was observed in 29.3 % pwMS. |
• | Abnormal QSART was identified in 17.3 % and SUDOSCAN in 10.7 % pwMS. |
• | There was no correlation between abnormal sweating symptoms and objective measures of sweating function. |
• | A positive correlation was observed between QSART volume of the foot and the SUDOSCAN ESC results for the corresponding leg. |
Abstract |
Objective |
To characterize sweating issues in people with multiple sclerosis (pwMS) using the Quantitative Sudomotor Axon Reflex Test (QSART) and SUDOSCAN.
Methods |
In 75 pwMS, sweating symptoms were evaluated using the Composite Autonomic Symptom Score (COMPASS-31). Sweating function was assessed with QSART and SUDOSCAN.
Results |
Symptomatic sweating problems were observed in 22 (29.3 %) pwMS. Pathological results of the QSART (sudomotor index (SI) > 0) were identified in 13 (17.3 %) pwMS, while SUDOSCAN results showed pathology in 8 (10.7 %) pwMS. We found a positive correlation between the QSART volume of the foot and the SUDOSCAN electrochemical skin conductance (ESC) results for the corresponding leg ( r = 0.282, p = 0.015). pwMS with cervical spinal cord lesions had higher ESC values for the hand mean, left, and right (69.88±12.84 vs 76.15±9.29, p = 0.022; 69.88±12.82 vs 76.22±9.36, p = 0.021; and 70.33±13.00 vs 76.52±9.27, p = 0.024; respectively).
Conclusions |
People with MS frequently experience sweating problems. Using various methods to identify sweating issues in pwMS reveals differences in the causes of these problems in pwMS.
