Cigarette smoking increases the relapse rate in patients with relapsing-remitting multiple sclerosis who are being treated with interferon-beta, a study suggests. The findings suggest that RRMS patients who smoke may have fewer relapses if they quit. An article on the results, “Smoking affects the interferon beta treatment response in multiple sclerosis,” appeared in the journal Neurology. A number of studies have looked at the link between environmental and lifestyle factors and the risk of developing MS. These factors include how much sunlight and vitamin D patients get and whether they have an Epstein-Barr virus infection. Cigarette smoking is a well-documented risk factor in MS, but most of the studies on it have focused on the link between smoking and MS, or the link between smoking and the disease's progression. “Studies that addressed the relationship between smoking and disease activity in RRMS are rarer,” the researchers wrote. The team decided to investigate whether smoking during interferon-beta treatment would affect relapse rates. Previous research had set the stage for the study by showing a link between smoking and gene mutations that make people more susceptible to developing MS. The mutations were in the HLA and NAT1 genes. The team looked at DNA from 834 RRMS patients in the Danish Multiple Sclerosis Biobank who were treated with interferon-beta. Well-known brand names of the treatment include Rebif, Avonex, and Plegridy. There are also other brand names and biosimilar drugs. Researchers also looked at patients’ medical records two years before they started on interferon-beta. Before making any conclusions on possible links between smoking and patients' relapse rate, the team adjusted for patients’ sex, age at the start of treatment, and number of relapses in the two years before treatment began. Their key conclusion was that smoking increased by more than a quarter the number of relapses in patients on interferon-beta therapy. “Each pack of cigarettes more per day during IFN-β [interferon-beta] treatment increased the number of relapses by 27%,” the team wrote. The researchers found no association among smoking, relapses, and mutations of the HLA or NAT1 genes. “Our results confirm that lifestyle factors are important in MS, suggesting that smoking cessation may be associated with a reduction in disease activity,” they wrote. “Although not formally proving that smoking cessation will decrease disease activity in RRMS, the results should encourage physicians to inform patients with MS about the harmful effect of smoking and increase focus on smoking cessation,” they observed.

The National Multiple Sclerosis Society will award $433,800 to 10 high-risk pilot studies that will quickly evaluate new strategies and interventions and enhance knowledge about multiple sclerosis (MS). According to a press release, the award winners will address different aspects of the disease, including potential treatments for fatigue and loneliness, to improve patients' walking abilities, and a strategy to change gut bacteria effects in MS. The year-long Pilot Research Grant program is a way to support early-stage research projects to quickly test their effectiveness. The MS Society also said that additional projects will be awarded this year. Results of a recent survey of approximately 300 pilot grant recipients revealed the program successfully promotes new ideas and brings new researchers to the MS field. About 90 percent of the respondents agreed that the financial support was very important for their research project. In 85 percent of cases, the grant supported new ideas, and in 56 percent it allowed support for additional grants. These pilot grants allow researchers to obtain preliminary data so they can decide to apply for additional funding, if the project looks promising, or to put the idea to rest.

One way the body may protect itself from nerve cell inflammation is to have cells in the blood-brain barrier increase their production of a protein that keeps immune cells from entering the brain, researchers in Germany and Canada report. The finding suggests that scientists could develop a multiple sclerosis therapy around the protein, known as EGFL7. It would work by preventing as many inflammation-generating immune cells from entering the brain. The underlying trigger for MS is immune cells crossing the blood-brain barrier to invade the central nervous system (CNS). The barrier is a selective membrane that shields the CNS from general blood circulation. Therapies that prevent immune cells from entering the brain can help control the disease, studies have shown. They include Tysabri (natalizumab, marketed by Biogen). But “as with other highly effective disease-modifying therapies which influence a broad range of peripheral immune cells, potential devastating adverse events limit the use of this therapy as a first-line agent,” the researchers wrote. The team at Mainz University Medical Center in Germany and the University of Montreal wondered if epidermal growth factor-like protein 7 (EGFL7) could prevent the brain inflammation in MS. Although scientists had not previously linked it to MS, it was shown to regulate the migration of immune cells into breast cancer tumors. The CNS response to the chronic inflammation seen in MS patients and a mouse model of the disease was to increase EGFL7 in the blood-brain barrier, the researchers found. Researchers said the increase prevented pro-inflammatory immune cells from crossing into the CNS. Endothelial cells that line blood capillaries in the blood-brain barrier are the ones that secrete EGFL7. “We postulate that EGFL7 upregulation by BBB-ECs [brain blood barrier-endothelial cells] is induced as a compensatory mechanism to promote survival and recovery of BBB function in neuroinflammatory conditions,” the team wrote. Researchers then tested what happened in mice that lacked EGFL7. They found that the mice developed MS earlier and that their blood-brain barrier membrane was less efficient at keeping immune cells out. Treatment with EGFL7 improved the disease severity in the MS mice and tightened the blood-brain barrier, they said. “In light of our findings, smaller EGFL7 agonists, in development for other diseases, could therefore constitute an appealing therapeutic avenue for MS,” the team concluded.
