Vitamins B12 and B9 (folic acid) supplements can lower levels of homocysteine (a common amino acid), improve anemia status, and boost self-reported physical health in patients with multiple sclerosis, according to new research. The study suggests a potential role for these two vitamins in improving the quality of life of MS patients. Despite treatment, MS patients often experience symptoms that interfere with their daily lives. Many patients have turned to dietary supplements with the hope they would reduce the severity of their symptoms. There is substantial literature suggesting the benefits of various supplements for MS, including vitamin B12 and folic acid. Homocysteine, of which high levels are associated with heart disease and detrimental effects in the nervous system, can be more prevalent in MS patients compared to healthy individuals. That suggests homocysteine is "one of the causative factors in the pathogenesis [development] of MS," researchers wrote. Lack of vitamin B12 — naturally found in meat, fish, poultry, eggs, and dairy products — can lead to a disruption in myelination, the process of forming a protective myelin coat around nerve cells. The loss of myelin is a hallmark of MS. A lack of folic acid, together with too little vitamin B12, has been linked to neurological symptom onset in MS patients. Meanwhile, vitamin B12 and folic acid supplements have shown promising results among these patients. In addition, MS patients are known to have an increased risk for the development of megaloblastic anemia — a condition in which the bone marrow produces unusually large, immature red blood cells referred to as megaloblasts. The most common causes of megaloblastic anemia are a deficiency of either vitamin B12 or folic acid. Based on these observations, researchers from Urmia University of Medical Sciences and Kermanshah University of Medical Sciences, in Iran, studied the effects of vitamin B12 and folic acid supplements in  relapsing-remitting multiple sclerosis (RRMS) patients. The team looked specifically at serum homocysteine levels, anemia status, and quality of life. This double-blinded clinical trial (IRCT2015100313678N7) enrolled 50 RRMS patients (age 20-40 years), who were divided into two groups: the vitamin group, which received three doses of 1 mg vitamin B12 injection (spaced a month apart) plus 5 mg folic acid tablets daily; and the placebo group, which received neutral saline injections. All participants completed two quality-of-life questionnaires, one geared toward physical health and the other toward mental health, at the start and end of the study. Blood samples were collected from all participants, and blood pressure readings were taken. Results showed a drop in average homocysteine blood serum levels in the vitamin group, which may be indicative of an improvement in nervous system health. Researchers also observed a decrease in mean corpuscular volume (MCV) in the vitamin group, which is indicative of improved anemia status. At the end of the study the vitamin group showed improvements in both physical and mental fields in the quality-of-life questionnaires. However, RRMS patients in the control group (without vitamin supplements) also had an increase in the quality-of-life questionnaire for mental health, obscuring any conclusions on the effect of vitamin supplements in MS patients’ mental health. “Results of the present study have shown that homocysteine levels, anemia status, and eventually the quality of life of patients with MS can be significantly improved by administration of 1 mg of vitamin B12 monthly and adding rich-food sources of folic acid on their diet,” the researchers wrote. The team nonetheless emphasizes that "further studies in the field of MS dietary patterns must be conducted."

Cigarette smoking increases the relapse rate in patients with relapsing-remitting multiple sclerosis who are being treated with interferon-beta, a study suggests. The findings suggest that RRMS patients who smoke may have fewer relapses if they quit. An article on the results, “Smoking affects the interferon beta treatment response in multiple sclerosis,” appeared in the journal Neurology. A number of studies have looked at the link between environmental and lifestyle factors and the risk of developing MS. These factors include how much sunlight and vitamin D patients get and whether they have an Epstein-Barr virus infection. Cigarette smoking is a well-documented risk factor in MS, but most of the studies on it have focused on the link between smoking and MS, or the link between smoking and the  disease's progression. “Studies that addressed the relationship between smoking and disease activity in RRMS are rarer,” the researchers wrote. The team decided to investigate whether smoking during interferon-beta treatment would affect relapse rates. Previous research had set the stage for the study by showing a link between smoking and gene mutations that make people more susceptible to developing MS. The mutations were in the HLA and NAT1 genes. The team looked at DNA from 834 RRMS patients in the Danish Multiple Sclerosis Biobank who were treated with interferon-beta. Well-known brand names of the treatment include Rebif, Avonex, and Plegridy. There are also other brand names and biosimilar drugs. Researchers also looked at patients’ medical records two years before they started on interferon-beta. Before making any conclusions on possible links between smoking and patients' relapse rate, the team adjusted for patients’ sex, age at the start of treatment, and number of relapses in the two years before treatment began. Their key conclusion was that smoking increased by more than a quarter the number of relapses in patients on interferon-beta therapy. “Each pack of cigarettes more per day during IFN-β [interferon-beta] treatment increased the number of relapses by 27%,” the team wrote. The researchers found no association among smoking, relapses, and mutations of the HLA or NAT1 genes. “Our results confirm that lifestyle factors are important in MS, suggesting that smoking cessation may be associated with a reduction in disease activity,” they wrote. “Although not formally proving that smoking cessation will decrease disease activity in RRMS, the results should encourage physicians to inform patients with MS about the harmful effect of smoking and increase focus on smoking cessation,” they observed.
