Abstract Category: Clinical aspects of MS - MS symptoms

Introduction: Neuropathic pain (NP) refers to pain arising as a direct consequence of a lesion or disease affecting the somatosensory system [1]. Its prevalence in Multiple Sclerosis has been reported as over 28% [2]. It has been shown to have considerable impact upon the various domains of health status [3].

Methods: 722 people with MS were recruited into the early stages of the longitudinal TONiC study. Each completed a questionnaire booklet with a range of scales, including the Neuropathic Pain Scale (NPS) [1].

Results: Mean age was 48.9 years (SD 11.6) with mean disease duration of 11.5 years (SD 9.1). Just under a third (32.1%) had a progressive form of MS. Almost two thirds (62%) had an EDSS of 4.5 or greater.

65.9% reported some aspect of NP (i.e. NPS>0). No difference was found in the NPS by age (Kruskal Wallis; p>0.642) or by gender (Mann Whitney p=>0.584). However, a significant difference was found for duration, incorporating a u-shaped curve, such that with those whose duration was less than 5 years, and those exceeding 17 years experienced the highest NP (Kruskal Wallis p=0.045). A significant gradient was also observed for disease subtype, where those with Secondary Progressive MS (SP) showed the highest levels of NP (Kruskal Wallis; p < 0.001). This may account for the u-shaped pattern to duration, as those with SP have the longest duration (F 55.3; p=< 0.001). A strong gradient was also observed for EDSS (Kruskal Wallis; p < 0.001). Significantly higher levels of NP were also reported for those not working (Mann Whitney U; p= 0.001). For those with an NPS score in the upper third of its range, the odds of being in work, adjusted for age, was reduced by 3.8 times.

Conclusion: Symptoms consistent with NP are common in MS, and in the current study almost two-thirds of respondents reported some such symptoms. Strong gradients of NP were observed across many clinical attributes, as well as for work status.
