To characterize the epidemiology of multiple sclerosis (MS) in Catalonia, a prospective registry of new cases of MS in Catalonia was set up in 2009 with the participation of 21 hospitals throughout Catalonia. Prevalence and incidence studies based on this population-based registry are being performed.
Recently, and in collaboration with the Center of Multiple Sclerosis of Catalonia (Cemcat), we have set up a prospective registry of vaccination in patients with Immuno-Mediated Inflammatory Disease (IMID) who are candidates for biological treatment with the aim of evaluating vaccine immunogenicity and safety that will allow establishing the best vaccination strategy. In addition, we will study the prevalence and impact of comorbidity on Multiple Sclerosis prognosis.
