info_outlineIn this episode of MD Newsline, Dr. Marianna Cortese, a medical doctor and epidemiologist at the Harvard T.H. Chan School of Public Health, shares groundbreaking research on the link between vitamin D, Epstein-Barr virus (EBV), and the risk of multiple sclerosis (MS). Her work, conducted within the U.S. military cohort, sheds new light on racial, genetic, and environmental factors influencing MS development and potential prevention strategies.
Dr. Cortese discusses how vitamin D levels and immune response modulation play a role in MS prevention, and how EBV infection—now recognized as the leading cause of MS—interacts with genetic susceptibility and immune regulation. She also explores the future of AI in epidemiological research, the challenges of defining “deficiency” across diverse populations, and how personalized medicine may change MS prevention and treatment.
Episode Highlights
Understanding the Vitamin D–MS Connection
Dr. Cortese explains her landmark study assessing vitamin D levels in over 1,400 MS cases and double the number of controls from a U.S. military cohort. The findings show that higher vitamin D levels are associated with a 60% lower risk of MS, even among individuals who already meet current “sufficient” vitamin D thresholds.
Epstein-Barr Virus as a Causal Factor
She details how EBV infection precedes nearly all MS diagnoses, increasing risk 32-fold in those infected compared to those who remain uninfected. The 2022 Science paper by her team was pivotal in confirming EBV as the primary cause of MS.
Racial and Genetic Differences in Vitamin D Physiology
Dr. Cortese emphasizes that Black populations may metabolize vitamin D differently, which could explain why prior studies found weaker associations between vitamin D levels and MS risk. Her ongoing work includes genotyping vitamin D transport proteins and analyzing ethnic variations in MS susceptibility.
Public Health Implications and Future Research
Given vitamin D’s safety, affordability, and widespread deficiency, Dr. Cortese advocates for revised supplementation guidelines tailored to disease prevention. She also highlights future research directions involving AI-driven data analysis, omics studies, and therapeutic vaccines or antivirals targeting EBV.
A Look Toward MS Prevention and Treatment
Dr. Cortese envisions a future where antiviral therapies against EBV could transform MS management—potentially leading to disease-modifying or curative interventions. Meanwhile, maintaining sufficient vitamin D remains a key, accessible step for reducing risk.
Key Takeaway
Dr. Cortese’s research bridges decades of inquiry into how vitamin D and EBV intersect to influence MS risk. Her findings reinforce the importance of immune health, genetic understanding, and early prevention, paving the way for more personalized and equitable approaches to neurological care.
