UNRELATED UMBILICAL CORD BLOOD TRANSPLANT FOR JUVENILE METACHROMATIC LEUKODYSTROPHY: A FIVE-YEAR FOLLOW-UP IN THREE AFFECTED SIBLINGS

Unrelated umbilical cord blood transplantation (UCBT) was used to treat three siblings with juvenile metachromatic leukodystrophy (jMLD). The efficacy of this therapy was measured over a five-year period with serial neurological exams, neuroimaging, nerve conduction studies (NCS), and neuropsychological evaluations (NPE). Outcomes were a function of disease stage at time of UCBT with alteration of disease course occurring in the first two years after UCBT and then subsequent halting of progression and stabilization of symptoms and disease.
