Utilization of the Ketogenic Diet in Patient With Relapsing Remitting MS

Relapsing Remitting Multiple Sclerosis Clinical Trial

Official title: The Effect of the Ketogenic Diet on Patients With Relapsing Remitting Multiple Sclerosis

Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate the benefits of a low-carbohydrate, high-fat diet (ketogenic diet) in up to 50 subjects with relapsing-remitting multiple sclerosis (RRMS), a chronic neuro-inflammatory disease. The primary aim of this study is to provide evidence of tolerability of the ketogenic diet in patients with RRMS. The principal investigator hypothesizes that the diet may prove beneficial for participants disease state in multiple potential ways.The study consists of 5 visits over a 12 month period. During these visits subjects will undergo fasting lab work, micro-biome sampling, neurological testing, body composition analysis, meeting with dietitian, and will be asked to complete surveys as well as a diet recall log.

Clinical Trial Description

The purpose of this study is to see if a high fat, low carbohydrate diet is safe and how it effects post trial diet habits, physique, and disease course in patients with relapsing remitting multiple sclerosis. In particular, multiple sclerosis is a neurodegenerative disorder that is characterized by inflammation, microglial inflammation, and hypoxia in its relapsing-remitting form.1 One of the hypothesized therapeutic mechanisms of ketogenic diets is related to its effect on decreasing glycolysis, decreasing reactive oxygen species (ROS), and increasing ATP production by mitochondria. Production of ROS and macrophage activation have been directly correlated with demyelination and axonal injury in multiple sclerosis.2,3 In mouse models with experimental allergic encephalomyelitis (EAE), a model disease in mice that has many similar properties to that of MS in humans, experiments have demonstrated that impairment of memory and spatial learning are directly correlated with increased cytokine and chemokine expression and ROS production. In EAE mice fed a ketogenic diet, there were noted improvements in motor disability, memory dysfunction, and CNS inflammation - which on the whole are suggestive that a ketogenic diet may have a multitude of benefits in patients with multiple sclerosis.

The study goal is to recruit 50 young adult or adult patients with relapsing-remitting multiple sclerosis that show interest in starting and maintaining a ketogenic diet for six months. Prior to initiating the diet, the study team will characterize each patient's disease by analyzing multiple factors - including baseline expanded disability status scale (EDSS) and annualized relapse rates (ARR). Throughout the course of the 12 month study participants will be asked to complete several patient reported outcomes, an online food diary recall, and track their diet compliance using urinary ketone testing strips provided by the study daily.In addition, the study team will also draw serum lab work every 3 months that we anticipate may be affected by the diet (including hemoglobin A1C, lipid panel, and cytokine profiles). Rectal swabs will be requested during the study to look at effects of the diet on the microbiome both pre and post diet. Additionally, activity monitors (accelerometers) will be worn by each subject for 1 week prior to initiation of the diet to provide evidence of pre-diet activity levels and at various times throughout the study for comparison. Participating patients will receive education on starting, maintaining, and stopping the 6 month diet by a nutritionist. The nutritionist will meet with patients at scheduled office visits and will be available for questions during the duration of the patients participation. Subjects will also undergo anthropometric assessments with a bodpod used to measure body mass as well.

All measures will be compared with statistical analyses, utilizing both pre and post diet values to help determine benefit of the diet on various aspects of the patient's overall health and wellness. ;
