ABSTRACT

INTRODUCTION:

Emerging evidence suggests the prognostic value of spinal cord (SC) pathology in multiple sclerosis (MS). However, the 2021 MAGNIMS-CMSC-NAIMS guidelines don't recommend routine SC MRI for disease monitoring. This study investigates the frequency of new asymptomatic and isolated SC lesions, exploring their potential to predict clinical activity and guide treatment decisions.

METHODS:

We enrolled relapsing-remitting MS (RRMS) patients who underwent brain and SC MRI at baseline and after 12 months. New, enlarged, or gadolinium-enhanced (Gd+) lesions on MRI were considered disease activity markers. Clinical relapses and treatment changes observed 3 months after the 12-month MRI were analyzed using regression analysis, evaluating their association with worsening SC findings.

RESULTS:

A total of 201 RRMS patients (56 males, 27.9%, mean age 42.5 ± 12.1 years, mean EDSS 2.7 ± 1.9) were included. Isolated worsening of T2 lesion burden in the SC occurred in 16 patients (8%), and 12 (6%) had Gd + lesions. Among patients without brain MRI activity (n = 138), regression analysis revealed a significant association between new Gd + SC lesions and clinical relapses within 3 months of the 12-month MRI (p = 0.024). Worsening SC findings (p = 0.021) and SC lesion enhancement (p = 0.046) emerged as key factors influencing disease-modifying therapy changes within 3 months in these patients. Notably, even without clinical symptoms, worsening SC findings significantly predicted treatment changes (p = 0.003).

CONCLUSION:

Our findings highlight the independent value of SC MRI findings in MS monitoring. Importantly, isolated and asymptomatic SC worsening significantly impacted treatment decisions.
