Multiple sclerosis patients have high levels of a protein called osteopontin in their cerebrospinal fluid and blood, making it a potential tool for diagnosing the disease and predicting its course, a study suggests. The research, “Osteopontin (OPN) as a CSF and blood biomarker for multiple sclerosis: A systematic review and meta-analysis,” was published in the journal PLOS One. Researchers wanted to know if levels of osteopontin in cerebrospinal fluid and blood could be a reliable biomarker for MS. To arrive at answer, they “conducted a systematic review and meta-analysis" of studies that had measured the protein's levels in cerebrospinal fluid and blood "in MS patients and controls." The team searched for studies in three databases — PubMed, Web of Science and Scopus. Out of 27 that met their criteria, they used 22 in the meta-analysis. All four types of MS were represented in the studies — clinically isolated syndrome, relapsing-remitting MS, secondary progressive MS, and primary progressive MS. There were three types of controls in the articles — healthy people, people with non-inflammatory neurological disorders, and people with inflammatory neurological disorders. Researchers' first observation was that all of the MS patients had higher levels of osteopontin than controls. The protein's levels were significantly higher in relapsing-remitting MS patients than in those with clinically isolated syndrome, the group with the lowest osteopontin levels. Levels were similar in the other types of MS. Patients with an active disease had significantly higher levels of the protein in their cerebrospinal fluid than those with a stable disease. The results supported previous studies' findings that osteopontin levels are higher than normal in the cerebrospinal fluid and blood of MS patients, strengthening the notion that it could be used as a biomarker for MS. “Given the fact that OPN [osteopontin] levels are higher during relapses, we think that by monitoring this biomarker,  we might be able to predict the disease course," the team wrote. "We propose that developing drugs modulating OPN concentration may be a new treatment strategy for MS."

Non-Hispanic whites, especially females, are more likely to die from multiple sclerosis (MS) than any other racial group, though blacks tend to die earlier, concludes a study by researchers at the University of Southern California’s Keck School of Medicine.

 Novartis' Gilenya and interferon beta-1b-based therapies stop multiple sclerosis patients' cognitive decline, a Phase 4 clinical trial shows. Gilenya (fingolimod) also reduces patients' relapses and the number of their brain lesions — areas where a protein coating that protects nerve cells has deteriorated, researchers found.

Scientists announced positive and encouraging outcomes from two clinical studies — running as part of the larger Human Vaccines Project — aiming to unravel the mechanisms that underlie our immune system’s ability to fight disease. The results are expected to shed light on unknown aspects of the immune system that scientists at the Human Vaccines Project, a public-private partnership, hope to translate into new trials for diseases linked to the immune system, such as multiple sclerosis. Results from the trials — the Human Immunome Program and the Immunity to Hepatitis B Vaccine study — were recently presented at the World Vaccine and Immunotherapy Congress in San Diego, California. In the ongoing Human Immunome Program, researchers are trying to fill a major knowledge gap in the components and mechanisms of the immune system that allow it to recognize various threats, from viruses, parasites and bacteria to cancer cells. They are using blood samples from healthy people to analyze, at an unprecedented depth, the whole repertoire of genes that make up the surface receptors of immune B- and T-cells, the core cells of the immune system’s defence mechanisms. Results will likely advance how scientists diagnose and treat various diseases, and could prompt the development of new, improved vaccines. "We are studying the immune systems of healthy individuals to identify common elements, which could be important for facilitating new and improved vaccines," James E. Crowe Jr., MD, director of Vanderbilt University Medical Center's Vaccine Center, the leading scientific institution of the Human Immunome Program, said in a press release. Researchers will cross the sequencing information with participants' microbiome composition — the natural community of microbes that reside in an organism and are key for a healthy immune system — and other health and sociodemographic characteristics. "We also plan to expand these studies to complete the catalog across different demographics and geographies and compare healthy subjects with individuals with immune-mediated diseases such as multiple sclerosis, cancer and Alzheimer's, which could also reveal novel diagnostic markers," Crowe said. The second study, the Immunity to Hepatitis B Vaccine trial — currently recruiting participants — aims to understand why some people achieve protection against Hepatitis B after a single vaccine shot, while others require up to three immunizations to acquire full immunity. Understanding why the immune system responds differently in individuals can help researchers improve existing vaccines and potentially lead to one-shot vaccines that provide long-term immunity for all populations. Researchers in this study are analyzing genes belonging to the innate-immune system — a general immune system response, not one tailored to specific threats — and observing that activation of these genes in certain immune cells can predict who will be a responder after a single shot of the Hepatitis B vaccine. Preliminary results of the Immunity to Hepatitis B Vaccine study were delivered in two separate sessions at the congress. One was given by Manish Sadarangani, director of the Vaccine Evaluation Center of the University of British Columbia and BC Children's Hospital Research Institute, and the by and Richard Scheuermann, director of the J. Craig Venter Institute in La Jolla, California. "These preliminary data points toward strategies to understand why some people respond better to vaccines than others," Sadarangani said. "Using single cell analyses, we now have the opportunity to probe vaccine-induced responses more effectively, to not only learn what happens immediately after vaccination, but to monitor responses over time and utilize machine learning to eventually predict the human immune response to vaccines," added Scheuermann. Wayne C. Koff, president and chief executive officer of the Human Vaccines Project, emphasized that researchers are optimistic with the results obtained so far, as they "provide important insights into the scale and complexity of the human immune system and how vaccines confer protective immunity." "With our network of academic and corporate partners, we aim to build on these findings and decode the human immune system, giving the world the tools required to advance the development of future vaccines and therapies to defeat major global diseases," Koff concluded.

Probiotics may improve the health of people with multiple sclerosis (MS) by reducing disability and improving inflammatory and metabolic parameters, an Iranian study shows. Live microorganisms linked to health benefits, known as probiotics, have long been known to help chronic disease patients. In a previous study of people with major depressive disorder, probiotics treatment for eight weeks improved patients’ depression and metabolic parameters. More recently, authors investigated the impact of probiotics on a group of MS patients, looking not only at mental health and metabolic indicators, but also disability scores. Researchers at Tehran's Shahid Beheshti Hospital recruited 60 MS patients, divided them in half, and assigned 30 to take a probiotic capsule and 30 a placebo once a day for 12 weeks. The probiotic contained the healthy bacteria Lactobacillus acidophilus, Lactobacillus casei, Bifidobacterium bifidum and Lactobacillus fermentum. Researchers measured patients’ health parameters and disability scores at baseline and after treatment. The results showed that probiotic intake after 12 weeks improved MS patients' disability scores (assessed by the expanded disability status scale, EDSS) when compared to placebo controls. Although this improvement was statistically significant, it was not clinically significant — which is defined as a change of 1.0 point or more at EDSS levels less than 5.5, or 0.5 point or more at EDSS levels greater than 5.5). Moreover, benefits were also detected in several mental health parameters – Beck Depression Inventory, general health questionnaire-28 (GHQ-28), depression anxiety and stress scale. Consuming probiotic capsules also significantly decreased insulin levels and high-density lipoprotein (HDL) cholesterol in circulation, researchers also found. It also lowered certain markers of inflammation and oxidative stress, such as serum high-sensitivity C-reactive protein (hs-CRP) and malondialdehyde (MDA).

A multiple sclerosis study will collect information about patients' movement performance and symptoms from their smartphones, Novartis has reported. The study is aimed at evaluating in real time the daily challenges of people living with MS. The results may help researchers develop new ways to measure treatments' effectiveness, the company said. Novartis is partnering on what it has dubbed the elevateMS study with Sage Bionetworks. The non-profit research organization is developing new predictors of disease to accelerate health research. A cellphone application will allow MS patients to send information about their situation from anywhere. The app will use sensors to gather information on patients' movements. It will also assess functional performance tasks that participants engage in. Patients can also fill out questionnaires with the app. A division of Apple called the Apple ResearchKit platform developed the app. Those interested in participating in the study can download it here. The elevateMS app allows a smartphone user to register important features of their disease. It includes a symptom tracker tool that allows users to record their overall wellness. They can also get an overview of what's been happening to them on an activity dashboard. Patients, neurologists and disease advocates gave Apple's app team input that helped with the design. "As physicians, we always want to know how our patients with MS are doing on the treatments we prescribe," Dr. Stanley Cohan, medical director of the Providence Multiple Sclerosis Center in Portland, Oregon, said in a press release. "With the elevateMS app, study participants can frequently document their symptoms in a personal health story," said Cohan, one of the scientific advisors to the study. "In turn, this data may provide researchers with new ways to look at disease progression and treatment effectiveness." The elevateMS study is open to MS patients 18 years old or older in the United States who own a smartphone. Additional information about it is available at www.elevatems.org.
