One of the earliest symptoms that appeared before my multiple sclerosis (MS) diagnosis was imbalance. I remember turning my head to look at something and feeling slightly off-balance. I didn’t think much of it at the time, but that wobbly sensation gradually increased through the years. Occasionally, I…

B-cells of patients with relapsing-remitting multiple sclerosis (RRMS) secrete substances that are toxic to both neurons and neuron-protecting myelin-forming cells, causing both kinds to die, according to a study. Despite analyses of numerous inflammatory and other factors believed to drive MS processes, researchers were unable to identify the molecules that are toxic, however. Dr. Robert Lisak of Wayne State University in Detroit, Dr. Amit Bar-Or of McGill University in Montreal and their teams are now working on identifying the factor, and learning if the process is also involved in progressive MS. Their study, “B-cells from patients with multiple sclerosis induce cell death via apoptosis in neurons in vitro,” was published in the Journal of Neuroimmunology. It demonstrated that B-cells gathered from the blood of RRMS patients killed lab-grown neurons and oligodendrocyte cells, which form myelin, a protecting coating for nerve cells. Deterioration of the myelin coating and the death of neurons are hallmarks of MS. An earlier study the team conducted indicated that B-cells from MS patients could kill oligodendrocytes. But since the experiments involved only three patients and three controls, the team scaled up their experiments to include 13 patients and an equal number of controls. Both rat and human neurons died when mixed with MS-derived B-cells. In contrast, B-cells from healthy people had little or no impact on the survival of the brain cells. Researchers also discovered that the secreted toxic molecules had no impact on other types of central nervous system cells — astrocytes and microglia. The toxins killed only neurons and myelin-producing cells. The B-cells triggered a process called apoptosis, or programmed cell death, researchers said. This is basically a suicide program. It tells a cell to die when exposed to stressful factors or toxins. The process differs from cell disintegration. Despite thoroughly screening about 40 inflammation-related substances, researchers were unable to identify any factors that caused the cells to die. The National MS Society and the Research Foundation of the MS Society of Canada funded the research, which the U.S. society highlighted in a news release. In the newest phase of the study, researchers will try to learn more about the processes underlying neuron and myelin-related cell deaths and identify the factors responsible. In addition to testing B-cells from progressive MS patients, the team will examine patients with other autoimmune conditions to see if the process is unique to MS or not. Researchers increasingly realize that B-cells are important to MS processes. This observation was underscored by U.S. regulators' approval of the B-cell depleting therapy Ocrevus (ocrelizumab) at treatment for both relapsing and primary progressive MS.

Problems with sense of smell are more frequent and severe in patients with primary progressive multiple sclerosis (PPMS) than in those with relapsing-remitting multiple sclerosis (RRMS), a study reports. The research, “Olfactory dysfunction in patients with primary progressive MS,” was published in the journal Neurology: Neuroimmunology and Neuroinflammation. A distinguishing feature of RRMS, the most common form of the disease, is attacks of new or increasing neurologic symptoms, such as movement disorders, and then recovery periods. About 15 percent of patients have the primary progressive form, or PPMS. Its main feature is gradually increasing neurologic disability without recovery periods. Some scientists believe PPMS is a less inflammatory course of MS. The differences in the processes that underlie each form are not well understood, however. Several researchers think that studying differences in the two groups' ability to smell — or olfactory dysfunction — could shed light on these underlying processes. Autopsies of MS patients in one study showed that 71 percent had experienced demyelination, or loss of neurons, in the brain's olfactory pathway. The processes that led to this dysfunction were unclear, however. Researchers decided to test the hypothesis that olfactory impairment is more pronounced in patients with PPMS than RRMS. The team examined 32 patients with PPMS, 32 with RRMS, and 32 healthy controls. The yardstick they used to evaluate sense of smell was the olfactory Threshold Discrimination Identification (TDI) Test. It involves patients smelling 48 sniffin' sticks. In addition to an overall TDI, there were subscores on olfactory threshold, odor identification and odor discrimination. Olfactory threshold refers to the lowest concentration of an odor that a person can detect. Researchers found olfactory dysfunction in 27, or 84 percent, of the PPMS patients; 10, or 31 percent, of the RRMS patients; and 1, or 3 percent, of the healthy controls. The TDI score and all subscores were significantly worse in patients with PPMS than in the controls, when considering patients of similar age and the same sex. The TDI score was also worse in PPMS patients than in the RRMS group, after adjusting for age, sex, MS disability level, the length of time patients had the disease, and patients' ability to identify and discriminate among odors. Researchers acknowledged limitations to the study. One was the small size of the groups in the research. Another was not using magnetic resonance imaging, or MRI, to measure olfactory pathway deterioration. Comparing the brain's olfactory pathway region with other brain regions in both the RRMS and PPMS groups could have shed light on the processes underlying the olfactory dysfunction differences between the two, researchers said. “The findings suggest that olfactory dysfunction might be a surrogate of neurodegeneration in these patients," the researchers wrote. "Studies correlating olfactory function with radiologic and clinical markers of disease progression would be of interest.”
