MS-related Death Rate in British Military Is Much Higher Than in Other Professions, Study Finds

British military personnel are at significantly higher risk of dying from multiple sclerosis than people in other occupations, a study reports. University of Southampton researchers had done a previous study of mortality rates by occupation by checking records of residents of England and Wales. They noticed that the death rate among MS patients in the armed forces was much higher than that of people in other professions over three successive decades. MS has a genetic component but is also influenced by environmental factors, including vitamin D deficiency, smoking and certain viruses. Researchers wanted to learn why so many military people die of MS, and the causes. The team looked at the death records of men aged 20-74 between 1979 and 2010. They compared military people's MS-related mortality rates and death rates from all motor neuron diseases with those of other occupations. They also compared rates across social classes, which in the military presumably means lower-ranking enlisted people, higher-ranking enlisted people, and officers. They discovered that the MS-related mortality rate among military people was significantly higher than in other professions. The death rate from MS was also significantly higher than the rate from all motor neuron diseases in the armed forces. Interestingly, military people did not have a higher MS-related death rate when the team divided those in the study into three social classes or when they compared the armed forces mortality rate to those of similar occupations, such as police and fire services. The consistency of the findings, together with the high statistical significance observed, indicated that the results were not due to simple chance or a problem with the study method, the team said. They speculated that the higher military death rate could stem from the close proximity in which military personnel live and work, which could facilitate the transmission of infections that have the potential to cause MS. The results conflicted with those of a study that analyzed hospital admissions due to MS in a population of former military personnel. It reported no increased incidence of MS-related admissions in former military people, compared with non-military controls. Since such cohort studies are less prone to bias, the Southampton team called for more research on the topic.

Sunscreen Compounds Suppress Multiple Sclerosis Symptoms in Mice, Study Reports

Two compounds found in sunscreens suppressed multiple sclerosis symptoms in mice, a study shows. The substances, known as salate derivatives, belong to a class of compounds called nonsteroidal anti-inflammatory drugs. Evidence from the 1970s suggested that higher vitamin D levels from getting more sunlight could reduce the rate of MS. Subsequent studies indicated this was unlikely, however. Researchers who noticed that ultraviolet light suppresses MS in mice hypothesized that this could be the reason for the reduced prevalence of the disease in tropical areas. University of Wisconsin researchers wondered if sunscreen would prevent ultraviolet light from suppressing MS in mice. The team, led by Dr. Hector F. DeLuca, an emeritus professor in the university's Department of Biochemistry, chose six commercially available sunscreens, then exposed the mice to UV radiation. Confirming previous findings, they observed that UV radiation decreased the severity of MS. But, unexpectedly, they discovered that when mice were not receiving ultraviolet light, some of the sunblocks suppressed their MS for up to 30 days anyway. An analysis revealed that the salate derivatives homosalate and octisalate were the sunscreen components responsible for suppressing MS. The two are esters of salicylic acid, a common medication for acne, psoriasis, warts, and dandruff. Further analysis showed that homosalate was able to suppress MS by itself, but octisalate needed to be combined with homosalate to achieve significant results. The team also discovered that the salates' effectiveness depended on the dose. The more that homosalate was applied, the better the result, they said. The only adverse effect of homosalate and octisalate was temporary skin irritation. The study indicated that salate esters' ability to suppress MS is not due to their sunblocking ability per se, because some of the sunscreen brands that did a good job of blocking sunlight did not suppress the disease. Salate derivatives are well-known inhibitors of the enzyme cyclooxygenase, or COX. Because COX-2 has been found in MS lesions, salate derivatives might improve MS by suppressing COX, the researchers said. Overall, “salates may be useful in stopping the progression of MS, and may provide new insight into mechanisms of controlling autoimmune disease,” the researchers concluded.

Kesimpta outperforms Aubagio among ethnically diverse groups

Kesimpta (ofatumumab) is more effective than Aubagio (teriflunomide) among people with multiple sclerosis (MS) from ethnically diverse groups, including Black and African American, Hispanic and Latino, and Asian individuals, according to an analysis of pooled clinical trial data. “Determining whether there are differences in how people respond…

I had smooth sailing on my Ocrevus infusion day

Where does the time go? Six months had passed since my last treatment, which meant it was time for another. After my August 2022 diagnosis of multiple sclerosis (MS), I was given only one option for treatment: Ocrevus (ocrelizumab), which is a disease-modifying therapy that’s used…

Probiotic eased pain and fatigue in RRMS, trial data show

A commercial probiotic supplement containing the yeast Saccharomyces boulardii significantly eased pain and fatigue, and improved mental health and quality of life, in people with relapsing-remitting multiple sclerosis (RRMS), according to data from a clinical trial in Iran. The probiotic, BioDigest, also reduced inflammation and oxidative stress, a form…

Benefits of ketogenic diet in RRMS may be long lasting: Study

Following a ketogenic diet — one that’s low in carbohydrates and rich in fat — for six months significantly reduced measures of body fat and fatigue, eased disease symptoms, and improved exercise capacity, cognition, and arm and hand dexterity in people with relapsing-remitting multiple sclerosis (RRMS), a study showed.

Newly discovered genetic variant tied to faster MS progression

Researchers identified a genetic variant that associated with faster multiple sclerosis (MS) progression and greater brain tissue damage, according to a study that combined data on more than 12,500 patients in North America, Europe and Australia. Unlike previously detected MS-related variants linked to the immune system, this variant sits…

Up at 9, in bed by 8, yet still no time?

My sleep schedule, according to mathematics, leaves me 11 hours — so what’s my problem? My current ultra-efficient carers arrive at 9:30 a.m. and usually get me into the wet room 15 minutes later. Maybe 20 if my bottom has been misbehaving. It’s been something of a miscreant ever since…

Ocrevus Limits Progression Equally in Black, White People With RRMS

Ocrevus (ocrelizumab) seems to be equally effective at stabilizing disease activity in Black and white patients with relapsing-remitting multiple sclerosis (RRMS), a U.S. study found. Disability levels and MRI disease markers remained generally unchanged over the two-year study in both groups, despite Black patients having more severe disability…
