The patient subsequently developed a PML-immune reconstitution inflammatory syndrome after the initiation of Fingolimod treatment, suggesting that immune reconstitution may occur even during Fingolimod induced lymphopenia.<jats:italic>Conclusion.<\/jats:italic>This report highlights the need for strict drug surveillance using MRI of Natalizumab-associated MS patients at the time of drug discontinuation and beyond. This is important with respect to pharmacovigilance purposes not only for Natalizumab, but also for alternative drugs used after Natalizumab discontinuation.<\/jats:p>","DOI":"10.1155\/2014\/307872","type":"journal-article","created":{"date-parts":[[2014,11,23]],"date-time":"2014-11-23T21:00:28Z","timestamp":1416776428000},"page":"1-4","source":"Crossref","is-referenced-by-count":13,"title":["PML-IRIS during Fingolimod Diagnosed after Natalizumab Discontinuation"],"prefix":"10.1155","volume":"2014","author":[{"given":"J.","family":"Killestein","sequence":"first","affiliation":[{"name":"Department of Neurology, MS Center Amsterdam, VU University Medical Center, P.O.
