Vitamin B12, Folic Acid Supplements Yield Multiple Benefits for MS Patients

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 withĀ multiple sclerosis, according to new research. The study suggestsĀ 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 ā€” naturally found in meat, fish, poultry, eggs, and dairy products ā€” 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 ā€” a condition in which the bone marrow produces unusually large, immature red blood cells referred to as megaloblasts. TheĀ most common causes ofĀ megaloblastic anemia are a deficiency of either vitamin B12Ā or folic acid. Based on these observations,Ā researchers from Urmia University of Medical Sciences and Kermanshah University of Medical Sciences, in Iran, studied the effects ofĀ vitamin B12Ā and folic acid supplements inĀ Ā relapsing-remitting multiple sclerosis (RRMS)Ā 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:Ā 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 theĀ placebo group, which receivedĀ 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.Ā 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 patientsā€™ mental health. ā€œResults 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,ā€ the researchers wrote. The team nonetheless emphasizes that "further studies in the field of MS dietary patterns must be conducted."

Continuous Use of Gilenya for Up to 3 Years Can Lead to 50% Drop in Annual Relapse Rates, Real-world Study Says

Multiple sclerosis patients who began treatment withĀ Gilenya and stayed with it continuously showed a more than 50 percent reduction in annual relapse rates, a real-world study following these people for up to three years found. Gilenya,Ā marketed by Novartis, is an oral disease-modifying treatment forĀ relapsing-remitting multiple sclerosis , approved in 2010. It acts by binding and modulating receptors ā€” called sphingosine-1-phosphate receptor ā€” on lymphocytes (adaptive immune cells). By binding to these receptors, Gilenya prevents lymphocytes from leaving the lymph nodes and reaching the brain and spinal cord, and so lower lymphocyte-induced inflammation and damage. Although several clinical trials have reported reduced annualized relapse rates (ARRs) upon treatment with Gilenya, few long-term real-life studies have examined the relapse rate reductions over a long term. A team, led by Novartis researchers and a scientist atĀ Central Texas Neurology Consultants,Ā collected MS patient data from the MarketScan database, a U.S. claims database including medical and pharmacy claims (bills submitted to health insurance providers), between 2009 and 2016. Among 9,312 MS patients in the database with at least one filled Gilenya prescription, 1,599 adults (mean age, 46) met the study's inclusion criteria, including having at least one inpatient or two outpatient claims, and a total of four years of continuous health plan enrollment. Among theseĀ 1,599 patients, all usedĀ Gilenya for one year (cohort 1), 1,158 (72.4%) took Gilenya continuously up to the start of year two (cohort 2), and 937 (58.6%) used the therapy up to the start of year three (cohort 3). Baseline analysis ā€” measures taken at the study's start ā€” showed that the most common MS-linked symptoms were disorders of the optic nerve and visual pathways (reported in 22-24%), followed by fatigue/malaise (20-21%). Hypertension (20-21%) and depression (15-16%) were the most common physical and mental comorbidities, respectively. The mean annualized relapse rates (AARs) at baseline in these three groups of patients ā€” cohorts 1 to 3 ā€” ranged between 0.48 and 0.51. A consistent reduction in ARRs was seen in all three groups: cohort 1 had a 0.25 ARR at the close of the first year, for a 51% reduction from the baseline rate; cohort 2 a 0.22 ARR at the start of year two, for a Ā 54% lowering in relapse rates from baseline; and cohort 3 had 0.23 ARR at the third year, amounting to a 53% reduction. As expected, when researchers calculated ARRs among patients with continuous Gilenya use over these three years, they found a greater reduction in annual relapse rates. Mean ARRs in continuous-use patients were 0.19 (a 61% reduction) during the first year, 0.18 (a 62% reduction) during the second year, and 0.18 (a 61% reduction) at the start of the third year. ā€œThis retrospective claims database study found that patients with MS who received fingolimod [Gilenya] therapy experienced a durable and sustained reduction in relapse rates over a 3-year period,ā€ the researchers wrote, with findings representingĀ ā€œa durable reduction in relapse rates by [more than] 50%.ā€ Reasons that some patients discontinued treatment were not a focus of this study, they added.

MMP-9 Protein a Possible Marker of PML in Tysabri-treated RRMS Patients, Study Suggests

A protein called MMP-9 could be a predictive marker of progressive multifocal leukoencephalopathy development in patients withĀ relapsing-remitting multiple sclerosis (RRMS)Ā who are being treated withĀ Tysabri (natalizumab), a study suggests. The study, ā€œDynamic changes of MMP-9 plasma levels correlate with JCV reactivation and immune activation in natalizumab-treated multiple sclerosis patients,ā€ was published in the journalĀ Nature Scientific Reports. Brain inflammation in multiple sclerosis patients occurs when immune cells breach the blood-brain barrier. This layer of cells protect the brain and its supporting fluids, such as cerebral spinal fluid (CSF), from dangerous agents circulating in blood. How easily immune cells can break through the blood-brain barrier depends on its porousness. For instance, it is known that decreasing the activity of matrix metalloproteinases (MMP) increases the protective layerā€™s permeability. Matrix metalloproteinases are a family of proteins responsible for the degradation of collagen and other proteins in the extracellular matrix, which provides structural and biochemical support to surrounding cells. One metalloproteinase, called MMP-9, has been extensively studied in multiple sclerosis. MMP-9 levels are elevated in the CSF of multiple sclerosis patients and considered a potential biomarker of disease activity and possible therapeutic target. Tysabri (marketed by Biogen) is one of the most effective treatments for RRMS currently available. It works by blocking the entry of immune cells into the brain. Tysabri is known to decrease MMP-9 levels in the CSF and serum in RRMS patients. However, Tysabri has been associated with an increased risk of developing progressive multifocal leukoencephalopathy (PML). This rare and often fatal viral disease, caused by the John Cunningham virus (JCV), is characterized by progressive damage and/or inflammation at multiple sites in the brain. The reduced migration of immune cells across the blood-brain barrier induced by Tysabri is thought to be the cause of this increased PML risk.Ā Whether MMP-9 is involved in this process has not been studied. To look at this, a team led by researchers from Sapienza University and Aldo Moro UniversityĀ in Italy investigated MMP plasma levels following Tysabri treatment in the context of JCV. The team specifically looked at how levels of MMP-9 were linked to disease-related processes. Samples from 34 RRMS patients being treated with Tysabri (intravenous dose of 300ā€‰mg every four weeks) were analyzed. As expected, results showed that MMP-9 plasma levels stabilized within one year of Tysabri treatment (up to 12 Tysabri infusions), although they began to steadily rise afterward (between 12 and 24 infusions). These increased MMP-9 plasma levels were not associated with clinical relapses in RRMS patients. "MMP-9 levels increased in plasma accordingly with [Tysabri] infusion number," the researchers wrote. In comparing JCV-positive and JCV-negative samples, the researchers observed an increase in MMP-9 plasma levels in JCV-positive samples. This result suggested that JCV circulation in peripheral blood could be implicated in the increase of MMP-9 levels. Interestingly, increased MMP-9 plasma levels were found to be correlated with immune cell activation. "Our findings suggest a potential pathogenic role of MMP-9 in the development of progressive multifocal leukoencephalopathy during [Tysabri] treatment, and its possible use as a marker of JCV reactivation,ā€ the researchers wrote. Future studies are nonetheless needed to confirm these findings in larger groups of RRMS patients.
