Relationships between multiple sclerosis patients and their intimate partners were enhanced when the couple worked together to make lifestyle changes, and to develop skills to improve communication, a study shows. 

A link between fat molecules called ceramides and worsening disease in overweight and obese people with multiple sclerosis appears to exist, a study reports, with its findings suggesting that ceramides prompt the growth of immune cells called monocytes, which in turn spurs disease progression. These results also strengthen the likelihood that lifestyle factors, like diet and weight, can act as disease modifiers, its researchers said. High body mass index has been linked to the risk of developing MS, but for reasons that aren't clear. One idea is that weight-induced differences in lipids (fat molecules) in the blood, because they are involved in several cellular signaling processes, may affect MS and its course in people with higher BMIs. To test this hypothesis, a team led by researchers at the Advanced Science Research Center (ASRC) at The Graduate Center and at the Icahn School of Medicine at Mount Sinai analyzed 54 patients with relapsing-remitting MS (MS), ages 18 to 60, and with normal or high BMIs (27 people in each group). Participants were followed for two years. BMI is a measure of body fat based on height and weight. A normal BMI is defined as one between 18.5 and 24.9, while a person is considered overweight with a BMI of 25–29.9, and obese it is 30 or higher. Researchers took blood samples, and looked for differences between the groups in terms of both immune cells and blood lipid profiles. They then validated their findings in a separate group of 91 RRMS patients. Patients with high BMIs tended to have more monocytes than those with normal BMIs. Monocytes can travel through the blood to tissues where they develop into macrophages, immune cells with various functions that are best known for "eating" invading bacteria. Monocytes can also travel to the brain and damage nerve fibers. Overweight and obese patients also had significantly higher levels of ceramides compared with normal-weight patients, and the researchers wondered if a link might exist between the two. Through a set of experiments in cells, they discovered that ceramides cause epigenetic changes in monocytes; that is, they alter the way their genomes are "read," so they alter gene activity. Specifically, ceramide-treated cells showed a type of epigenetic change called methylation — which generally turns genes "off" — in genes that normally help prevent cells from dividing. Conceptually, these genetic changes serve to unleash monocytes, leading them to grow more (proliferate) than they otherwise might. The researchers also found more methylation on the genomes of monocytes from high-BMI patients than those from low-BMI patients, and they noted that the overweight or obese patients also tended to have greater disease activity, worse disability progression, and more brain lesions on MRI (magnetic resonance imaging) scans on follow-up. Finally, the researchers tested a mouse model of MS, giving one group of mice a standard diet and another a high-fat diet. Mice fed the high-fat diet were found to have greater disease severity, more brain lesions, and more monocytes, confirming the findings seen in MS patients. "This study gives us a much-needed view into the environmental influences that can affect and change the behavior of cells in an individual's body," Kamilah Castro, the study's first author, said in a press release. "Our findings suggest that increased levels of saturated fat as a result of dietary habits are one likely cause of the epigenetic changes that advance MS, which gives us a starting point for a potential intervention." According to the team, the findings support the concept of nutri-epigenomics: that is, the ability of food to alter the way the genetic information is interpreted by each cell, and suggest that "weight management and dietary intervention" might affect MS prognosis. One limitation was the study's small size, its researchers noted. "While we consider our results … very exciting and mechanistic, we acknowledge that the potential consideration of ceramide levels as biomarkers for disease progression in MS would require validation ... using larger cohorts with a longitudinal and/or cross-sectional design," they concluded. "It will also be important to evaluate the effectiveness of dietary intervention (with an emphasis on the reduction of specific classes of saturated fats), as potential modulator of plasma ceramide levels and possibly of disease course in MS patients."

Changeable lifestyle factors influence the risk and severity of depression associated with multiple sclerosis (MS), a study based on a large group of patients shows. According to the study, alcohol consumption in particular was linked negatively with depression incidence and severity. In addition, a healthy diet and vitamin D and omega-3 supplementation…

People with multiple sclerosis (MS) who quit smoking have better health outcomes than those who continue. Therefore, MS-related costs can be reduced by encouraging smokers to quit. Similar results were observed in MS patients with healthy vitamin D levels, Maura Pugliatti, from the University of Ferrara, in Italy, said Friday in a presentation at the…

A clear association was seen between the substantial pain that multiple sclerosis (MS) patients experience and lifestyle choices that either augment or ease that pain, like smoking habits, exercise, and diet and weight, researchers in Australia report. Common co-morbidities associated with MS, such as depression, anxiety, and fatigue, were also…

Older men with multiple sclerosis (MS) have more harmful lifestyles than older women with the disease, concludes the Canadian Survey of Health, Lifestyle and Aging with Multiple Sclerosis. Treatment for depression could go a long way to promoting more healthy lifestyles for all older MS patients, authors suggest. The study, “…

In a cross-sectional study, researchers found that sexual dysfunction in patients with multiple sclerosis (MS) is linked to fatigue and depression. Treating these factors and identifying their causes is a potential strategy to treat the problem. The study, “Sexual function in multiple sclerosis and associations with demographic, disease…
