CMV infection has been reported in MS patients treated with alemtuzumab, rituximab, and ocrelizumab, but its occurrence in patients receiving dimethyl fumarate (DMF) is less studied.<\/jats:p>\n <\/jats:sec>\n \n Objectives<\/jats:title>\n This case report explores the potential relationship between DMF therapy and CMV infection in a relapsing\u2010remitting MS (RRMS) patient, examining whether DMF\u2010induced immune modulation contributed to CMV reactivation or primary infection.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A 29\u2010year\u2010old male with RRMS, on DMF for four years without lymphopenia, developed elevated liver enzymes and splenomegaly. CMV serology showed IgG (60.7\u2009U\/L) and IgM (140.0\u2009U\/L), with detectable viral DNA (524\u2009IU\/mL). Epstein\u2013Barr virus (EBV) IgG was positive, but IgM was negative. Hepatitis A\/B, herpes simplex virus (HSV), and varicella tests were negative. DMF was paused for 3\u2009months, and antiviral therapy led to reduced liver enzymes and CMV DNA levels. MS remained stable without new MRI lesions.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n DMF therapy may contribute to CMV infection despite the patient\u2019s normal lymphocyte counts. It may be beneficial with routinely test with viral panel with patients with progression in MS. Further studies are needed to clarify the risk of CMV infection in DMF\u2010treated MS patients.<\/jats:p>\n <\/jats:sec>","DOI":"10.1155\/crnm\/6694528","type":"journal-article","created":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T16:56:57Z","timestamp":1760893017000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Cytomegalovirus Infection in a Multiple Sclerosis Patient on Dimethyl Fumarate"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-1191-2790","authenticated-orcid":false,"given":"Nicolai","family":"Larsen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,10,19]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.molmed.2014.11.002"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/s43856-022-00076-w"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.3109\/10428194.2014.910654"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00415-021-10661-z"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/ofid\/ofy174"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00109-019-01761-5"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/ofid\/ofz445"},{"key":"e_1_2_10_8_2","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.1601532"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.1099\/vir.0.052142-0"},{"key":"e_1_2_10_10_2","doi-asserted-by":"publisher","DOI":"10.5694\/mja14.00183"}],"container-title":["Case Reports in Neurological Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crnm\/6694528","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/crnm\/6694528","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crnm\/6694528","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T19:05:41Z","timestamp":1773774341000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/crnm\/6694528"}},"subtitle":[],"editor":[{"given":"Isabella Laura","family":"Simone","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2025,1]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,1]]}},"alternative-id":["10.1155\/crnm\/6694528"],"URL":"https:\/\/doi.org\/10.1155\/crnm\/6694528","archive":["Portico"],"relation":{},"ISSN":["2090-6668","2090-6676"],"issn-type":[{"value":"2090-6668","type":"print"},{"value":"2090-6676","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1]]},"assertion":[{"value":"2025-03-29","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-09-30","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-10-19","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"6694528"}}
