Levels of a protein stemming from brain cell damage can mirror the severity and symptoms of multiple sclerosis, an analysis of combined data from three trials showed. Researchers will present this and related findings at the annual meeting of the American Academy of Neurology in Los Angeles, April 21-27. The…

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."

Blood levels of the nerve damage marker neurofilament light provide a reliable picture of multiple sclerosis activity in both the relapsing-remitting and progressive forms of the disease, a Swedish study reports. The University of Gothenburg researchers also discovered a close link between its levels in blood and spinal fluid. This means the…

The Mayo Clinic has developed a test that allows doctors to distinguish other inflammatory demyelinating diseases from multiple sclerosis in the early stages of a disorder. The test, the first of its kind in the United States, looks for an antibody against a protein known as myelin oligodendrocyte glycoprotein…

Opioid growth factor (OGF) can serve as a new biomarker to determine diagnosis and progression of multiple sclerosis (MS), say researchers at Pennsylvania State University. Their study, “Serum [Met5]-enkephalin levels are reduced in multiple sclerosis and restored by low-dose naltrexone,” appeared in the journal Experimental Biology and…

Scientists have discovered the first blood biomarker for multiple sclerosis (MS) –  a chemical identifier in the blood. The discovery should lead to a simple blood test that makes it quicker and easier to follow the course of MS, a debilitating disease of the central nervous system affecting around 2.3 million people…

In its effort to end progressive multiple sclerosis (MS), the International Progressive MS Alliance (PMSA) has awarded a $6.1 million grant to fund a research project led by Dr. Douglas Arnold with the Montreal Neurological Institute Hospital (MNI) at McGill University. The multiyear grant is one of three…

Researchers from Karolinska Institute, Sweden, reported that the immune-associated protein lipocalin-2 (LCN2) is increased in multiple sclerosis, particularly in patients with progressive MS. The researchers, however, concluded that the factor cannot be used as a biomarker for the disease. The study, “Lipocalin-2 is increased in progressive multiple sclerosis…

A recent study published in the journal PLOS ONE described a new technique with the potential to spot brain changes in multiple sclerosis (MS) before the onset of symptoms. The technique, which measures brain dynamic activity and brain entropy, may lead to the development of diagnostic — and possibly prognostic —…
