Lower serum 25-hydroxyvitamin D(3) levels are associated with a substantially increased subsequent relapse rate in pediatric-onset multiple sclerosis or clinically isolated syndrome, providing rationale for a randomized controlled trial of vitamin D supplementation.
Cognitive deficits occur in children with multiple sclerosis. Comprehensive treatment planning should involve recognition that they may require academic accommodations for their education.
Fatigue and quality of life are significant concerns in adult multiple sclerosis (MS) but little is known about these factors in pediatric MS. The present investigation evaluates fatigue and quality of life in 51 pediatric MS patients to determine the rate of fatigue and reduced quality of life and assesses the relations between these variables and clinical factors. Fatigue and quality of life were assessed by self- and parent-report via the PedsQL Multidimensional Fatigue Scale and the PedsQL Quality of Life Scale. One-sample t-tests determined if scores were below published data for healthy individuals. Moreover, scores falling one standard deviation from norms were considered mildly affected, with severe difficulties being defined as scores falling two or more standard deviations from norms. Associations between self- and parent-reported difficulties and clinical factors were examined via Pearson correlation analyses. In comparison with healthy samples, pediatric MS patients reported greater difficulties with respect to fatigue, sleep, cognition, physical limitations, and academics. In addition to significant difficulties on these factors, parents reported problems with respect to emotional functioning, and tended to report greater fatigue, sleep, and cognitive difficulties than were self-reported. Expanded Disability Status Scale score was the only neurologic variable significantly related to fatigue or quality of life scores. Fatigue was significantly correlated with reports of sleep difficulties, cognitive problems, and quality of life variables. These findings suggest that fatigue and poorer quality of life is a clear concern in pediatric MS, and is related to overall physical disability.

Although Multiple Sclerosis (MS) occurring in childhood and adolescence has received increasing attention in recent years, the impact of the disease on cognitive function in this subgroup remains poorly understood. It has been posited that children and adolescents with MS may be particularly susceptible to cognitive dysfunction because the pathological processes, including inflammation, blood brain barrier breakdown, and demyelination, occur concurrently with ongoing myelination. Early work has documented that a number of these children present with cognitive deficits. However, there is no available information on the progression of these deficits, or on what clinical factors may predict further decline. The current article reviews what is currently known about pediatric MS and follows a cohort of pediatric MS patients and assesses cognitive function longitudinally. Participants were evaluated with a brief neuropsychological test battery on two separate occasions and correlational analyses assessed the relations between changes in cognition and several clinical variables including level of neurologic impairment, number of relapses prior to baseline assessment, number of interim relapses, age of disease onset, and disease length. The results indicate that a number of these patients experience further cognitive decline over time, or decline from previously normal functioning. Baseline level of neurologic disability was significantly correlated with changes in cognition. The number of interim relapses (i.e., relapses occurring between baseline assessment and re-evaluation) showed a modest relationship to changes in cognitive function, but this did not reach statistical significance.
The diagnosis of pediatric multiple sclerosis (MS) is challenging due to its low frequency and the overlap with other acquired childhood demyelinating disorders of the central nervous system. To identify potential protein biomarkers which could facilitate the diagnosis, we used two-dimensional gel electrophoresis (2-DE) in combination with mass spectrometry to identify proteins associated with pediatric MS. Plasma samples from nine children with MS and nine healthy subjects, matched in aggregate by age and gender, were analyzed for differences in their patterns of protein expression. We found 12 proteins that were significantly up regulated in the pediatric MS group: alpha-1-acid-glycoprotein 1, alpha-1-B-glycoprotein, transthyretin, apoliprotein-C-III, serum amyloid P component, complement factor-I, clusterin, gelsolin, hemopexin, kininogen-1, hCG1993037-isoform, and vitamin D-binding protein. These results show that 2-DE in combination with mass spectrometry is a highly sensitive technique for the identification of blood-based biomarkers. This proteomic approach could lead to a new panel of diagnostic and prognostic markers in pediatric MS.
Although psychological distress and cognitive dysfunction are well documented in adults with multiple sclerosis (MS), they are poorly understood in children with the disease. Psychosocial difficulty experienced by children and adolescents with MS involves factors common to all chronic illnesses in children, as well as MS-specific factors. The psychosocial manifestations of the disease may affect the patient's self-image, role functioning, mood, and cognition to adversely affect schooling, interpersonal relationships, and treatment compliance. Furthermore, the impact of having a family member with MS may affect overall family functioning. Assessment and interventions for psychosocial and cognitive problems in pediatric MS should be multidisciplinary in nature and address the child's functioning at home, school, and among peers, as well as the effect on the family.
Little is known about psychiatric aspects of pediatric demyelinating conditions. A total of 23 youths (6-17 years) with demyelinating conditions underwent semistructured psychiatric interviews using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version. Adolescents and parents completed the Child Symptom Inventory-4 and the Youth's Inventory-4. Fears and conceptions of their neurological problems were elicited. In all, 48% (n = 11) met criteria for current psychiatric diagnoses, including 27% (n = 3) with depressive disorders and 64% (n = 7) with anxiety disorders. Fears and conceptions of the illness were severe and diverse. Depressive and anxiety disorders are common in pediatric demyelinating disease. Clinicians should therefore screen for psychiatric comorbidity symptoms as part of the routine evaluation of such patients.
