Abstract Details

Early clinical and MRI predictors of long-term disability in pediatric multiple sclerosis patients
Multiple Sclerosis

The main clinical and MRI features driving therapeutic choices are not as clear for pediatric multiple sclerosis (MS) patients as for adults.

We aimed at assessing early predictors of long-term clinically-relevant outcomes in a large cohort of pediatric multiple sclerosis (MS) patients.

Clinical and MRI assessments of 123 pediatric MS patients were obtained at disease onset and after 1, 2 and 3 years. A 9-year clinical follow-up was evaluated for long-term outcomes. Cox proportional hazard and multivariable regression models were respectively used to assess independent predictors of time to first relapse and long-term outcomes.

Optic nerve lesions predicted shorter time to first relapse (hazard ratio=1.9, p=0.03). Predictors of annualized relapse rate were: at baseline, presence of cerebellar (b=-0.16, p<0.001) and of cervical cord lesions (b=0.14, p=0.01); over the short-term, the same baseline variables together with time to first relapse (2-year: b=-0.12, p=0.01; 3-year: b=-0.08, p<0.001) and number of relapses (1-year: b=0.14, p<0.001; 2-year: b=0.06, p=0.02). Predictors of 9-year disability worsening were: at baseline, presence of optic nerve lesions [odds ratio (OR)=6.45, p=0.01]; over the short-term, Expanded Disability Status Scale (EDSS) changes (1-year: OR=26.05, p<0.001; 2-year: OR=16.38, p=0.02) and detection of ≥2 new T2-lesions in 2 years (2-year: OR=4.91, p=0.02; 3-year: OR=5.49, p=0.09). Predictors of higher 9-year EDSS score were: at baseline, EDSS score (b=0.58, p<0.001), presence of brainstem (b=0.31, p=0.04) and number of cervical cord lesions (b=0.22, p=0.05); over the short-term, EDSS changes (1-year: b=0.82, p<0.001; 2-year: b=0.79, p<0.001, 3-year: b=0.27, p=0.04 ), together with detection of ≥2 new T2-lesions (1-year: b=0.28, p=0.03; 2-year: b=0.35, p=0.01).

A complete baseline MRI assessment and an accurate clinical and MRI monitoring during the first 2 years of disease have proven to represent powerful tools to predict pediatric multiple sclerosis patients’ long-term prognosis.
