relapse risk

Undergoing fertility treatment with assistive reproductive technologies does not increase the likelihood of having a relapse for women with multiple sclerosis (MS) who are taking a disease-modifying therapy (DMT), according to a new analysis. “The results are reassurance for women with MS who plan to undergo assistive reproductive…

People who start treatment with Tysabri (natalizumab) soon after being diagnosed with multiple sclerosis (MS) are at a lower risk of relapse in the long term compared with patients who start on less effective disease-modifying therapies (DMT), a study has found. Patients on Tysabri, an antibody-based therapy,…

Children with multiple sclerosis (MS) who start on high-efficacy therapies experience fewer relapses and reduced MRI disease activity in the following years, compared with those who are treated first with moderate-efficacy therapies, according to a new study. Rates of severe side effects are similar for both groups, but the…

A high level of adherence to disease-modifying therapies (DMTs) is associated with a significant, 25% lower risk of moderate or severe relapses in previously untreated people with multiple sclerosis (MS) compared with those failing to adhere to therapy, according to a study of real-world data in Italy. High…

People with multiple sclerosis (MS) who switch between more than two disease-modifying therapies (DMTs) have a higher risk of relapses compared with those who never switch, regardless of how well these patients adhere to their prescribed medications, according to real-world study in Canada. These findings are consistent with…

Disease relapses are no more likely in women with multiple sclerosis (MS) after fertility treatment than they were before such treatment, a study found. Researchers also observed that almost half of the women receiving fertility treatment were on disease-modifying MS therapies, which may have helped to keep a…

Fertility treatments do not significantly increase the risk of relapse in women with multiple sclerosis (MS), even among those who undergo treatment protocols associated with greater levels of hormone exposure, according to a recent U.S.-based analysis. Older age, a longer MS duration, and the use of MS disease-modifying…

Levels of certain inflammatory proteins in the cerebrospinal fluid, the liquid around the brain and spinal cord, may help predict the risk of relapse activity for individuals with early multiple sclerosis (MS), a new study found. High levels of three such proteins were predictive of a greater risk of…

Using a two-step machine learning strategy, researchers have developed an algorithm to predict the risk of multiple sclerosis (MS) relapse based on data gleaned from electronic health records. “The two-step machine learning model predicts a patient’s future one-year MS relapse risk with clinically actionable accuracy, comparable to other clinical…

Women with multiple sclerosis (MS) who receive high-efficacy disease-modifying therapies (DMTs) before conception have a greater risk of relapses and disability progression during pregnancy than those given moderate-efficacy or no DMTs, according to a systematic review of studies. Exclusive breastfeeding for at least two to four months, however,…

Getting the Pfizer-BioNTech vaccine for COVID-19 does not increase the risk of multiple sclerosis (MS) relapses in the two months following vaccination, according to a new study. The results support recommending COVID-19 vaccines for people with MS, its researchers said. “The incidence of relapses in the 2 months before and…

Ocrevus (ocrelizumab) reduces relapse risk and slows disability progression in multiple sclerosis (MS) but also is associated with higher hospitalization rates in older people with relapsing forms of the disease, a new observational study reports. Hospitalizations — which occurred mainly due to urinary tract infections — were more frequent…

Diet can play an important role in whether children with relapsing multiple sclerosis have a relapse, researchers at the University of California, San Francisco argue. Their study demonstrated that a diet with a lot of fat increases the risk of a youngster having a relapse by 56 percent, with saturated fat tripling the risk. Eating a lot of vegetables, on the other hand, cuts the risk in half, the team said. Since children with MS tend to have relapses more often than adults, the researchers figured they would be a suitable group to study diet's impact on relapse. They recruited 219 children with relapsing-remitting MS or clinically isolated syndrome from 11 centers across the U.S. Clinically isolated syndrome is a condition that can evolve in MS. The research team use a questionnaire known as the Block Kids Food Screener to analyze what the youngsters ate. They tracked the children an average of almost two years, which was plenty of time for relapses to occur. And, in fact, they did occur in 42.5 percent of the group. It turned out that fat had a particularly devastating effect on the youngsters' relapse rate. For every 10 percent increase in energy intake that came from fat, there was a 56 percent increase in the children's risk of having a relapse. Saturated fats were the biggest driver of risk. When researchers look only at these fats, they discovered that the risk more than tripled. Examples of saturated fats include processed meats such as sausages, ham, and burgers, butter, hard cheeses, and whole milk. Vegetables had the opposite effect on risk, the researchers observed. Using a cup equivalent as a standardized measure, they learned that for every additional cup of vegetables the children ate, the risk of a relapse dropped in half. To exclude the possibility that other factors influenced the results, the team included information about age, sex, ethnicity, duration of disease, body mass index, treatment, and D-vitamin levels in their analyses. This did not influence the results. The team also looked at whether other food components, such as sugar, iron, fruit and fiber, would affect the risk of relapse. They did not find any links. Although the risk associations were strong, the researchers cautioned that the study's observational design meant that it was not able to prove that fat causes relapses. But there are several ways that fat could play a role in disease processes, they argued. For instance, high fat intake triggers the release of inflammation-promoting molecules. It also affectsf gut bacteria that are linked to immune processes. Vegetables lower the risk of inflammation and immune problems, the team said. In an accompanying editorial, Dr. Kathryn Fitzgerald of the Johns Hopkins School of Medicine said the study had important limitations. Researchers gathered information on the children's diet only in the week before they enrolled in the study. This might not adequately capture more long-term dietary patterns, she said. And fat is not simply fat, she pointed out, arguing that fish oil is believed to help MS patients. Although the California research offers insight, she called for long-term studies to define diet's role in MS.
