Acute idiopathic transverse myelitis in children: early predictors of relapse and disability.

Objective: To identify early prognostic factors of relapse and disability in children presenting with an acute idiopathic transverse myelitis (TM).

Methods: Ninety-five children with acute idiopathic TM from 2 national European cohorts (France and United Kingdom) of CNS demyelinating diseases in children were identified and studied for early factors that predict relapse and disability using logistic regression models.

Results: Sixteen (17%) relapsed, with a diagnosis of multiple sclerosis in 13 (14%) and neuromyelitis optica in 3 (3%).
