AB  - Objective: To investigate the association between red meat restriction in diet and disease severity in multiple sclerosis (MS) patients. Background: Multiple genetic and environmental factors have been suggested to play a role in pathophysiology of MS. There is evidence that some nutritional elements, present in animal-derived products, can stimulate chronic inflammation and increase the risk of MS. Design/Methods: Data from MS patients enrolled in Comprehensive Longitudinal Investigation of Multiple Sclerosis at Brigham and Women’s Hospital (CLIMB) study who completed a questionnaire on dietary habits throughout their lives were included. Using a multiple linear regression model, MS severity scale (MSSS) at the time of questionnaire was compared between patients who had a diet restriction (n=70) and patients who never had any diet restriction (n=122). We ran the same analysis between the groups who reported red meat diet restriction (n=34) and never restricted red meat group (n=122). Furthermore, the number of relapses were compared via a Wilcoxon signed-rank test in patients who reported information on their restriction start dates (n=15) via the following intervals: 2 years prior and after the self-reported red meat restriction age. Results: The majority of patients in both groups were older, relapsing-remitting MS female patients with a BMI classified as overweight (BMI > 25.0). There was no significant difference in log-transformed MSSS between patients who had a diet restriction and patients who never had a diet restriction (mean difference= -0.15, 95[percnt]CI=(-0.51,0.21); p=0.42). This difference was also not significant for red meat restricted diet patients compared to the patients who never restricted red meat (mean difference=0.15, 95[percnt]CI=(-0.33,0.62); p=0.55). Red-meat restriction did not significantly affect number of attacks in the periods of 2-years before compared to 2-years after start of a diet (p=0.94). Conclusion: Our findings suggest that red-meat diet restriction has no significant effect on disease severity.Disclosure: Dr. Sattarnezhad has received research support from Merck Serono.
