However, disseminated infections and organ involvement are rare, usually occurring in immunocompromised individuals, particularly after hematopoietic stem cell or solid organ transplantation. HSV1\/2\u2010induced hepatitis is infrequent but can result in acute liver failure (ALF) and increased mortality. We present a case of fulminant ALF caused by disseminated primary HSV2 infection in a fifty\u2010year\u2010old male with rheumatoid arthritis treated with the JAK\u2010inhibitor upadacitinib for 3\u2009months prior to presentation. Clinical examination revealed severe oropharyngeal mucositis and hepatic encephalopathy. Initial laboratory results showed bicytopenia, significantly elevated transaminases, bilirubin, inflammatory markers, and severe coagulopathy. Empirical treatment with an antimicrobial regimen, intravenous aciclovir, acetylcysteine, and plasmapheresis (PPH) was initiated. The patient was listed for urgent liver transplantation based on King\u2019s College criteria. Further investigations revealed a high viral load of HSV2 DNA in the blood, and transjugular liver biopsy confirmed extensive liver necrosis with positive HSV staining. Despite antiviral therapy, the HSV2 viral load remained high, indicating resistance, and the patient was deemed \u201cnontransplantable\u201d due to clinical deterioration with progressive hepatic coma, hemorrhagic\u2013septic shock, multiorgan failure, and secondary bowel ischemia, ultimately leading to the patient\u2019s death from refractory shock. This is only the second documented case of fulminant ALF due to HSV2 hepatitis in a patient undergoing JAK inhibition, and the first involving upadacitinib. It highlights the importance of considering primary herpesvirus infection as a potential cause of ALF, particularly in immunocompromised patients, and underscores the need for early antiviral intervention to improve outcomes.<\/jats:p>","DOI":"10.1155\/crhe\/1414531","type":"journal-article","created":{"date-parts":[[2025,7,23]],"date-time":"2025-07-23T08:09:54Z","timestamp":1753258194000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Fatal Liver Failure After Herpes\u2010Simplex\u2010Virus\u20102\u2010Induced Acute Necrotizing Hepatitis: A Case Report"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-2863-239X","authenticated-orcid":false,"given":"Thomas","family":"R\u00f6sner","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Grenz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marlene","family":"Schaum\u00e4ker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"Cuntz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9419-1690","authenticated-orcid":false,"given":"Norbert","family":"Blank","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7383-1898","authenticated-orcid":false,"given":"Alphonse","family":"Charbel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2040-6246","authenticated-orcid":false,"given":"Christa","family":"Flechtenmacher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0401-5600","authenticated-orcid":false,"given":"Patrick","family":"Michl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Pfeiffenberger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monica","family":"Boxberger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7354-0241","authenticated-orcid":false,"given":"Isabelle","family":"Mohr","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,7,23]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmjgh-2020-002388"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.lanepe.2022.100558"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/jit458"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1056\/nejmra1208937"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0140-6736(19)31894-x"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/lt.21250"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1155\/2020\/8613840"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1080\/00365540310016015"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/463825"},{"key":"e_1_2_9_10_2","doi-asserted-by":"publisher","DOI":"10.1097\/cce.0000000000000745"},{"key":"e_1_2_9_11_2","doi-asserted-by":"publisher","DOI":"10.1097\/md.0000000000027139"},{"key":"e_1_2_9_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/jca.21287"},{"key":"e_1_2_9_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhep.2016.12.003"},{"key":"e_1_2_9_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/0016-5085(89)90081-4"},{"key":"e_1_2_9_15_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-3148.2009.00951.x"},{"key":"e_1_2_9_16_2","doi-asserted-by":"publisher","DOI":"10.4236\/crcm.2015.42015"},{"key":"e_1_2_9_17_2","doi-asserted-by":"publisher","DOI":"10.1155\/2011\/138341"},{"key":"e_1_2_9_18_2","doi-asserted-by":"publisher","DOI":"10.1023\/a:1005699210816"},{"key":"e_1_2_9_19_2","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/3180984"},{"key":"e_1_2_9_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0140-6736(22)00581-5"},{"key":"e_1_2_9_21_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.41032"},{"key":"e_1_2_9_22_2","doi-asserted-by":"publisher","DOI":"10.1002\/ygh2.413"},{"key":"e_1_2_9_23_2","doi-asserted-by":"publisher","DOI":"10.1086\/422364"},{"key":"e_1_2_9_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0151-9638(07)89193-9"},{"key":"e_1_2_9_25_2","doi-asserted-by":"publisher","DOI":"10.1111\/tid.13562"},{"key":"e_1_2_9_26_2","first-page":"68","article-title":"Acyclovir Pharmacokinetics in Plasmapheresis","volume":"5","author":"Chavanet P.
