A Scoping Review of Modifiable Risk Factors in Pediatric Onset Multiple Sclerosis: Building for the Future

Multiple Sclerosis-Related Dietary and Nutritional Issues: An Updated Scoping Review with a Focus on Pediatrics

PURPOSE

Lifestyle/dietetic habits play an important role in the development and progression of multiple sclerosis (MS) disease. Here, we examine the basic pathomechanisms underlying intestinal and brain barrier modifications in MS and consider diets and dietary supplementations proposed over time to complement pharmacological therapies for improving disease outcome both in adults and in children.

METHODS

Scoping literature search about evidence-based findings in MS-related gut-brain axis (GBA) pathophysiology and nutritional issues at all ages.

FINDINGS

Data show that (1) no universal best diet exists, (2) healthy/balanced diets are, however, necessary to safeguard the adequate intake of all essential nutrients, (3) diets with high intakes of fruits, vegetables, whole grains, and lean proteins that limit processed foods, sugar, and saturated fat appear beneficial for their antioxidant and anti-inflammatory properties and their ability to shape a gut microbiota that respects the gut and brain barriers, (4) obesity may trigger MS onset and/or its less favorable course, especially in pediatric-onset MS. Vitamin D and polyunsaturated fatty acids are the most studied supplements for reducing MS-associated inflammation.

CONCLUSIONS

Pending results from other and/or newer approaches targeting the GBA (e.g., pre- and probiotics, engineered probiotics, fecal-microbiota transplantation), accurate counseling in choosing adequate diet and maintaining physical activity remains recommended for MS prevention and management both in adults and children.

Sleep counts! Role and impact of sleep in the multimodal management of multiple sclerosis

BACKGROUND

In the last years, research on pharmacotherapy and non-pharmacological approaches to Multiple Sclerosis (MS) has significantly increased, along with a greater attention to sleep as a clinical outcome measure. This review aims to update the state of the art on the effects of MS treatments on sleep, but above all to evaluate the role of sleep and its management within the current and future therapeutic perspectives for MS patients.

METHOD

A comprehensive MEDLINE (PubMed)-based bibliographic search was conducted. This review includes the 34 papers that met the selection criteria.

RESULTS

First-line disease modifying therapies (especially the interferon-beta) seem to have a negative impact on sleep, assessed subjectively or objectively, while second-line treatments (in particular, natalizumab) do not seem to lead to the onset of daytime sleepiness (also evaluated objectively) and, in some cases, an improvement in sleep quality has been observed as well. Management of sleep is considered a major factor in modifying disease progression in pediatric MS; however, probably because only fingolimod has recently been approved in children, information is still scarce in this group of patients.

CONCLUSIONS

Studies on the effect of drugs and non-pharmacological treatments for MS on sleep are still insufficient and there is a lack of investigations on the most recent therapies. However, there is preliminary evidence that melatonin, chronotherapy, cognitive-behavioral therapy, and non-invasive brain stimulation techniques might be further assessed as adjuvant therapies, thus representing a promising field of research.

Needs and Experiences of Children and Adolescents with Pediatric Multiple Sclerosis and Their Caregivers: A Systematic Review

In the present study we conduct a systematic review to evaluate the needs and experience of people with pediatric multiple sclerosis (MS) and their caregivers. The literature search was conducted across 10 academic databases, adhering to PRISMA-P guidelines. Quality appraisal was conducted using the mixed method appraisal test for individual studies, and GRADE-CERQual to establish overall confidence of findings. Results were analyzed using a process of narrative synthesis. We identified 26 studies which included 2253 children/adolescents with MS (CAMS) and 1608 caregivers. MS was reported to negatively impact experiences for CAMS in domains such as of school performance, social relationships, mental health, and overall physical functioning. Specifically, fatigue and social support were reported as the most important barriers and facilitators for CAMS, respectively. In terms of caregiver experience, negative impacts were reported on social functioning, mental health, and quality of life. Additionally, lack of awareness concerning MS was one of the biggest challenges reported. Caregivers expressed needs for psychological and social support. This study provides the first evidence regarding the needs and experiences of CAMS and their caregivers. Findings can be used to address policy gaps for supporting families affected by pediatric MS.

Improving Outcomes in Pediatric Multiple Sclerosis: Current and Emerging Treatments

Pediatric-onset multiple sclerosis (MS) comprises 2-5% of MS cases, and is known to be associated with high disease activity and the accumulation of disability at an earlier age than their adult-onset counterparts. Appropriate therapy leading to disease control has the potential to alter the known trajectory of adverse long-term physical, cognitive, and psychosocial outcomes in this population. Thus, optimizing treatment for children and adolescents with MS is of paramount importance. The last decade has seen a growing number of disease-modifying therapies approved for relapsing MS in adults, and available agents now include oral, injectable, and infusion therapies. Recently, the development of randomized controlled MS trials in youth has led to the first agent approved by the US FDA for the treatment of pediatric MS-fingolimod. With this, we have entered a new era of knowledge and treatment in this population and ongoing pediatric trials are expected to further inform clinical management. With the emergence of highly effective therapies targeting the inflammatory component of the disease, there has been increased interest in identifying treatment strategies that instead target mechanisms such as remyelination/repair, neuroprotection, or rehabilitation. The potential role for such emerging therapies in the treatment of pediatric MS remains an important area of study. In this review, we discuss current evidence for MS therapies in children including the treatment of acute relapses, disease-modifying therapies, and symptomatic management. We will also discuss evidence for emerging therapies, including remyelinating and neuroprotective agents.

Cognitive Functioning in Patients with Pediatric-Onset Multiple Sclerosis, an Updated Review and Future Focus

Pediatric-onset multiple sclerosis (POMS) is relatively rare, but as technology and neuroimaging advance, an increasing number of cases are identified, and our understanding of how multiple sclerosis (MS) impacts the developing brain improves. There are consistent findings in the literature highlighting the impact of MS and other demyelinating diseases on cognitive functioning and cognitive development. We also have a better understanding of how POMS impacts psychosocial functioning and functional outcomes in daily living. This paper hopes to review findings associated with cognitive and psychosocial functioning in patients with POMS, as well as explore more recent advances in the field and how they relate to cognitive and psychosocial outcomes. We also discuss the ongoing need for future studies with a focus on better understanding deficits and disease correlates, but also preventative measures and potential rehabilitation.
