NEW ORLEANS—Two studies presented at the 31st Annual Meeting of the Consortium of Multiple Sclerosis (MS) Centers examined the impact of MS and treatment among patients who are members of an online social network. Researchers found that, among patients who were taking oral disease-modifying treatments (DMTs), how the drug was taken was the most important factor in selecting the therapy (36% of patients) almost as often as the doctor’s recommendation (40% of patients), according to the results of a patient survey. In a separate study that analyzed comments made on the social network, researchers found that adverse events were the most commonly stated reason for stopping a treatment (56%).

In one study, Terrie Livingston, PharmD, an employee of Biogen in Weston, Massachusetts, and colleagues conducted a patient survey to assess the impact of MS on day-to-day life, self-reported symptoms, patient descriptions of disability progression, trade-offs when deciding which DMT to take, and what health care providers should know to better manage MS.
In November 2014, researchers sent an email invitation to the entire MyMSTeam community, a social network of approximately 25,000 people (currently more than 75,000 people) diagnosed with MS. In all, 1,107 members responded to the survey.
Overall, the most commonly reported symptoms were fatigue (82% of patients), problems with mobility (64%), and poor balance (64%). In addition, weakness, cognitive issues, and depression were common. The respondents defined disability progression as increased limitations on their ability to get around, having to sacrifice normal daily activities, and losing their ability to be independent. Patients measured the efficacy of DMTs by evaluating the treatments’ ability to slow progression, prevent further physical disability, prevent new lesions, and improve quality of life.
In a separate study, Dr. Livingston and colleagues conducted an analysis of organic discussions within MyMSTeam from January 2015 to April 2016. Researchers anonymized, coded, categorized, and analyzed 3,300 verbatim comments by key themes. The analysis focused on 12 DMTs. Discussions were overlaid with patient self-reported data on gender, age, date of diagnosis, MS type, current DMT, and effectiveness ratings.
Common discussion topics included side effects experienced; reasons for stopping treatment; perceived efficacy; questions, hopes, and concerns about starting a new DMT; rituals to mitigate side effects; and insurance or financial hurdles to getting on or staying on treatment.
Discussions about infusion therapies tended to focus on receiving treatment and issues related to progressive multifocal leukoencephalopathy.
When discussing Tysabri (natalizumab), patients most commonly discussed elevated energy levels post infusion around day 14. Patients also reported increased fatigue in the days prior to the next infusion and extreme fatigue on the day of treatment. In addition, patients shared their experiences with managing tolerability issues, most commonly flu-like symptoms with interferons and gastrointestinal effects with Tecfidera (dimethyl fumarate).
Dr. Livingston and colleagues said that their research “will better allow medical professionals to treat the individual holistically, and not just the disease itself. Additionally, helping patients understand MS progression will allow specialists to set realistic expectations for treating the disease and to help their patients better prepare for the future.”
