A recent study suggests that there may be a link between MS progression and blood lipids in MS patients who are overweight or obese.  The study  published in the Lancet journal EBioMedicine supports previous research that hints food, diet, and exercise can help affect disease progression in MS patients.

The study was conducted by researchers at the Advanced Science Research Center at the Graduate Center of the City University of New York’s Neuroscience Initiative in collaboration with clinicians at the Icahn School of Medicine at Mount Sinai and assessed recently diagnosed MS patients, studying their MS progression for two years.

  The researchers found that overweight or obese patients had higher levels of blood lipids called ceramides. These lipids placed markers on the DNA of monocytes, making them proliferate. Monocytes  are blood cells that have the ability to damage nerve fibers when they travel to the brain.  Two years into their diagnosis, participants of this study with more ceramides and monocytes also had greater brain injury and loss of motor skills.

Two patient cohorts – a primary one and a validation group – were recruited from the Corinne Goldsmith Dickinson Center for Multiple Sclerosis at Mount Sinai and the National Institutes of Health to participate in the study. For the first group, 54 therapy-naïve MS patients 18 to 60 years old with high or normal BMIs were evaluated for signs of brain damage using brain MRI, a clinical assessment to ascertain weight, disabilities, and other vital information; and blood tests to analyze the types of circulating lipids and white blood cells. An independent validation group of 91 MS patients from the NIH with the same characteristics and additional control cohorts of healthy individuals within the same BMI range were also evaluated.

Researchers found that high-BMI MS patients showed worsening disability and more brain lesions at the MRI compared to their normal BMI counterparts.

The results suggest that saturated fatty acids may have long-lasting functional effects, which over time steer the MS disease course towards worsening disability. Net net, bad dietary habits may have negative consequences in healthy subjects, but they have an even more pronounced deleterious effect on patients with MS because the degrading myelin can accumulate and further increase ceramide levels.

Additional research is needed to determine whether specific dietary changes and weight management can be beneficial  in helping MS patients manage and slow the progression of their disease and better respond to disease-modifying treatments.

That’s a wrap #AAD2023! 5 days of soaking up knowledge from dermatologists on topics such as hidradenitis, melasma, & dietary triggers of common dermatoses.

I LOVED the #womenshealth focused sessions on vulvar dermatoses and pregnancy medication safety.


New approach uses microbiome to treat skin disease by repairing the injured microbiome that allowed inflammation to flare up in the first place, rather than reducing the inflammation after the fact. https://bit.ly/3Jt6H9v
