Prognostic factors and predictive model for severe multiple sclerosis at first onset in a pediatric French cohort.
OBJECTIVE: To identify key prognostic factors and develop a predictive model for poor-prognosis forms of pediatric-onset multiple sclerosis (POMS) in a French cohort.
METHODS: Between 2000 and 2017, 70 children with POMS were included. Severe disease was defined as ≥3 relapses and/or a final Expanded Disability Status Scale (EDSS) score above 0. Because EDSS may underestimate disability in children, a sensitivity analysis was performed using ≥3 relapses alone to define severity. Clinical, biological, and radiological characteristics were compared between severe and non-severe cases to identify prognostic factors and construct a predictive model.
RESULTS: At the last follow-up, 49 of 70 patients (70 %) were classified as having severe POMS. Using the alternative definition based solely on relapse count, 32 patients (46 %) were considered severe. The main prognostic factors-shorter interval between the first two relapses, older age at onset, and higher lesion load on initial MRI-were consistent across both definitions, confirming the robustness of the model. The final predictive model included time between the first two attacks, age, sex, number of juxtacortical lesions, and CSF pleocytosis. The prognostic tree achieved a specificity of 89 % and 84 %, and a sensitivity of 76 % and 68 % under the two respective definitions.
CONCLUSION: Specific clinical and radiological markers may allow early identification of severe POMS. Based on these markers, we developed a predictive model that could help identify high-risk patients and guide early, individualized treatment strategies. Validation in an independent cohort is warranted to confirm its clinical applicability.
