Medications for Multiple Sclerosis and Risk of Malignancy: What Next?

ABSTRACT: Many autoimmune diseases confer a higher risk of cancer on patients compared to the general population. A controversial factor tying autoimmune diseases to malignancy is harm from immunosuppressive treatment. Nonetheless, multiple sclerosis is different from other autoimmune diseases, and findings from other disease populations may not apply. In this issue of Neurotherapeutics, Dolladile and colleagues from France present new evidence about the risks of cancers in patients with multiple sclerosis treated with disease-modifying therapies based on analyses of spontaneous reporting data. This commentary discusses the context, limitations, and implications of these findings.

Project description:BACKGROUND:Multiple sclerosis (MS) is a chronic neurological disease occurring mostly in women of childbearing age. Pregnant women with MS are usually excluded from clinical trials; as users of the internet, however, they are actively engaged in threads and forums on social media. Social media provides the potential to explore real-world patient experiences and concerns about the use of medicinal products during pregnancy and breastfeeding. OBJECTIVE:This study aimed to analyze the content of posts concerning pregnancy and use of medicines in online forums; thus, the study aimed to gain a thorough understanding of patients' experiences with MS medication. METHODS:Using the names of medicinal products as search terms, we collected posts from 21 publicly available pregnancy forums, which were accessed between March 2015 and March 2018. After the identification of relevant posts, we analyzed the content of each post using a content analysis technique and categorized the main topics that users discussed most frequently. RESULTS:We identified 6 main topics in 70 social media posts. These topics were as follows: (1) expressing personal experiences with MS medication use during the reproductive period (55/70, 80%), (2) seeking and sharing advice about the use of medicines (52/70, 74%), (3) progression of MS during and after pregnancy (35/70, 50%), (4) discussing concerns about MS medications during the reproductive period (35/70, 50%), (5) querying the possibility of breastfeeding while taking MS medications (30/70, 42%), and (6) commenting on communications with physicians (26/70, 37%). CONCLUSIONS:Overall, many pregnant women or women considering pregnancy shared profound uncertainties and specific concerns about taking medicines during the reproductive period. There is a significant need to provide advice and guidance to MS patients concerning the use of medicines in pregnancy and postpartum as well as during breastfeeding. Advice must be tailored to the circumstances of each patient and, of course, to the individual medicine. Information must be provided by a trusted source with relevant expertise and made publicly available.
