DMF can induce lymphopenia, which is assumed to increase the risk for opportunistic infections like progressive multifocal leukoencephalopathy. Our goal for this work was to estimate the frequency of grade 3 lymphopenia in DMF-treated patients with RRMS and to characterize patient-sided factors influencing the time course of lymphocyte repopulation after DMF withdrawal %K adverse event %K age %K fumarate %K multiple sclerosis %K lymphocytes %K white blood cells %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6506915/
