Passive acquisition of various clinically important antibodies through these therapies can occur, leading to false serology and negatively affecting patients' clinical care. It is recommended that dermatologists recognize the possibility of these phenomena and interpret them appropriately. Here, we report false\u2010positive serology following intravenous immunoglobulin therapy and plasma exchange through transfusion of fresh frozen plasma in a patient with refractory pemphigus vulgaris. We also discuss the measure for misinterpretation and unnecessary clinical intervention.<\/jats:p>","DOI":"10.1111\/1346-8138.12785","type":"journal-article","created":{"date-parts":[[2015,2,6]],"date-time":"2015-02-06T12:26:59Z","timestamp":1423225619000},"page":"398-400","source":"Crossref","is-referenced-by-count":5,"title":["False\u2010positive serology following intravenous immunoglobulin and plasma exchange through transfusion of fresh frozen plasma in a patient with pemphigus vulgaris"],"prefix":"10.1111","volume":"42","author":[{"given":"Hisashi","family":"Nomura","sequence":"first","affiliation":[{"name":"Department of Dermatology Shizuoka Municipal Shimizu Hospital Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haruki","family":"Honda","sequence":"additional","affiliation":[{"name":"Department of Dermatology Shizuoka Municipal Shimizu Hospital Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shohei","family":"Egami","sequence":"additional","affiliation":[{"name":"Department of Dermatology Shizuoka Municipal Shimizu Hospital Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1094-3569","authenticated-orcid":false,"given":"Tomoaki","family":"Yokoyama","sequence":"additional","affiliation":[{"name":"Department of Dermatology Shizuoka Municipal Shimizu Hospital Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atsushi","family":"Fujimoto","sequence":"additional","affiliation":[{"name":"Department of Dermatology Shizuoka Municipal Shimizu Hospital Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makiko","family":"Ishikawa","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine Shizuoka Municipal Shimizu Hospital Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makoto","family":"Sugiura","sequence":"additional","affiliation":[{"name":"Department of Dermatology Shizuoka Municipal Shimizu Hospital Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,2,6]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2133.2003.05665.x"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2011.03.032"},{"key":"e_1_2_5_4_1","doi-asserted-by":"crossref","first-page":"1237","DOI":"10.5858\/2002-126-1237-PATAFI","article-title":"Passively acquired treponemal antibody from intravenous immunoglobulin therapy in a pregnant patient","volume":"14","author":"Rossi KQ","year":"2002","journal-title":"Arch Pathol Lab Med"},{"key":"e_1_2_5_5_1","doi-asserted-by":"crossref","first-page":"3423","DOI":"10.1128\/JCM.37.10.3423-3424.1999","article-title":"Intravenous immunoglobulin therapy: confounding effects on serological screening for toxoplasmosis during pregnancy","volume":"14","author":"Pelloux H","year":"1999","journal-title":"J Clin Microbiol"},{"key":"e_1_2_5_6_1","first-page":"529","article-title":"Passively acquired antibody to hepatitis B surface antigen.
