It seemed to be such a harmless rabbit hole. After last week’s column on Rolfing — and a response divided between those who thought it sounded like terrible torture and those who agreed it was torture but they liked it — I decided to explore some other ideas…

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."
A global collaboration of researchers led by Belgium’s Flanders Institute for Biotechnology has determined the structure of the pro-inflammatory cytokine IL-23 and its receptor IL-23R, which could be potential targets for treating multiple sclerosis (MS) and other autoimmune diseases.

A Tough Year to Fight the Flu
I’m fighting a cold. I’m coughing and I’m congested. I’m hoping it’s not the flu. This is not a year to get the flu. The type of flu circulating in most of North America right now is the H3N2 variety. And, in the words of Helen Branswell…
A novel imaging approach enables assessment of key nervous system deterioration in multiple sclerosis (MS), a new study in mice suggests. The research, “Development of a PET radioligand for potassium channels to image CNS demyelination,” was published in the journal Scientific Reports. MS is characterized by damage to myelin (a process called demyelination), which is an insulating sheath around axons (the long projections of neurons) that enables effective neuronal communication. As a result, patients experience a variety of symptoms, including muscle stiffness and weakness, fatigue and pain. Although existing MS medications suppress immune responses and reduce flare-ups, none can cure the disease. Despite the importance of demyelination in MS, scientists and clinicians do not currently have a way to directly image myelin damage. Magnetic resonance imaging (MRI) is used, but it does not enable the distinction between demyelination and inflammation, which are common in patients with MS. Upon myelin damage, voltage-gated potassium channels (cellular membrane proteins) become exposed. As a result, cells leak potassium, which impairs proper neuronal communication. This prompted researchers to develop a tracer that targets potassium channels. "In healthy myelinated neurons, potassium channels are usually buried underneath the myelin sheath," Brian Popko, PhD, the study’s senior author, said in a press release. Popko is a professor of neurological disorders and director of the Center for Peripheral Neuropathy at The University of Chicago. Exposed potassium channels can be targeted by the MS medication 4-aminopyridine (4-AP; dalfampridine), which partially repairs nerve conduction and mitigates MS symptoms. Using mouse models of MS, the researchers demonstrated that 4-AP binding to potassium channels is greater in demyelinated axons in comparison with well-myelinated axons. The greater binding of 4-AP led to its accumulation in damaged axons. Then, the team evaluated several fluorine-containing derivatives of 4-AP, and found that the most effective in binding to potassium channels was 3-fluoro-4-aminopyridine (3F4AP), which can be labeled with radioactive 18F. This labeling enables detection of demyelinated regions with a novel strategy based in positron emission tomography (PET). "3F4AP is the first tracer whose signal increases with demyelination, potentially solving some of the problems of its predecessors," said Pedro Brugarolas, PhD, first author of the study. Existing PET tracers bind to myelin. This translates to decreases in signal in the presence of myelin loss, “which can be problematic for imaging small lesions” Brugarolas noted. Importantly, the findings in mice were confirmed in monkeys. Experiments showed that the radiolabeled 3F4AP enters the primate brain and accumulates in areas with less myelin. Collectively, “these data indicate that [18F]3-F-4-AP may be a valuable PET tracer for detecting [central nervous system] demyelination noninvasively,” the team wrote. "We think that this PET approach can provide complementary information to MRI which can help us follow MS lesions over time," Popko said. The novel PET strategy enables the evaluation of therapies to repair myelination and also could help assess how much myelin loss is involved in other neurological disorders, such as traumatic brain injury and spinal cord injury, but also in diseases not commonly linked to demyelination, "such as brain ischemia, psychiatric disorders, and neurodegenerative diseases, including Alzheimer's," Popko concluded.

Diagnosing MS Faster and Better
As we all know, MS is difficult to diagnose. Put another way, it’s easy to misdiagnose. There’s no single diagnostic test for MS. Neurologists use their clinical examination, the patient’s medical history, and lab tests. They also rely on MRI imaging of the brain and sometimes of the…
The nerve-cell-protecting myelin sheath’s failure to remove cholesterol after the membrane has been damaged limits its ability to regenerate, German researchers report. Their finding has important implications for multiple sclerosis because a hallmark of the disease is nerve cell deterioration stemming from damaged myelin. Cholesterol is a waxy, fatty substance…

A deterioration in multiple sclerosis patients' handwriting aligns with drops in their movement, sensory and cognitive skills, a study reports. MS includes loss of hand dexterity and finger movement control. This affects a patient's capacity to manipulate objects and coordinate hand movement, skills needed in handwriting. Previous studies have shown that MS patients had less handwriting rhythm and control than healthy people. This time researchers decided to compare the handwriting movements of both MS patients and healthy volunteers. The research involved 19 MS patients and 22 healthy age-matched controls. The team asked participants to write a specific sentence on a digitizing tablet. They discovered that the way MS patients wrote was much different than those of the controls. The patients took a lot longer to write each word and to achieve spacing between words. This led to them taking a much longer time overall to write a sentence than healthy people. In addition, analysis of handwriting strokes showed that MS patients' writing wasn't as smooth as that of healthy people. Researchers also found a correlation between patients’ movement abilities and cognitive status on the one hand and their handwriting ability on the other. The team said it believed “these findings might be very useful when planning rehabilitative task-oriented interventions focused on handwriting abilities.” In fact, rehabilitation specialists should consider evaluating “both the motor movement and the cognitive status of PwMS [patients with MS] in order to tailor the intervention."
