This study aimed to conduct a recent epidemiological analysis of patients with pustular psoriasis who were enrolled in the JSPR from 2017 to 2020. A total of 291 patients from 131 medical institutions were enrolled, of which 47.4% (138 cases) were males and 52.6% (153 cases) were females. The mean\u2009\u00b1\u2009standard deviation (SD) age of the patients was 57.4\u2009\u00b1\u200920.3\u2009years (males, 61.2\u2009\u00b1\u200917.3\u2009years; females, 54.1\u2009\u00b1\u200922.1\u2009years). The mean\u2009\u00b1\u2009SD age of the patients at disease onset was 48.5\u2009\u00b1\u200922.5\u2009years (males, 50.8\u2009\u00b1\u200920.6\u2009years; females, 46.4\u2009\u00b1\u200924.0\u2009years). The types of pustular psoriasis observed included the von Zumbusch type (59.8%), annular pustular psoriasis (8.2%), impetigo herpetiformis (6.5%), and acrodermatitis continua of Hallopeau (4.8%), of which, the majority of the patients with impetigo herpetiformis were female. Among the patients, 58.4% were treated with oral medications and 44.0% were treated with biologics. The most common oral medication prescribed was etretinate (52.4%), followed by corticosteroids (24.7%) and cyclosporin (22.9%). The most common biologics used were IL\u201017 inhibitors (ixekizumab [28.1%] and secukinumab [22.7%]), followed by tumor necrosis factor (TNF) inhibitors (infliximab [15.6%]) and IL\u201023 inhibitors (guselkumab [14.8%] and risankizumab [10.2%]). This survey thus provides new and significant information regarding the recent perspective of pustular psoriasis, such as patient characteristics and treatment trends, in Japan.<\/jats:p>","DOI":"10.1111\/1346-8138.16583","type":"journal-article","created":{"date-parts":[[2022,9,24]],"date-time":"2022-09-24T16:31:16Z","timestamp":1664037076000},"page":"3-11","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Epidemiological survey of patients with pustular psoriasis in the Japanese Society for Psoriasis Research from 2017 to 2020"],"prefix":"10.1111","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7938-1947","authenticated-orcid":false,"given":"Koji","family":"Kamiya","sequence":"first","affiliation":[{"name":"Department of Dermatology Jichi Medical University  Shimotsuke Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mamitaro","family":"Ohtsuki","sequence":"additional","affiliation":[{"name":"Department of Dermatology Jichi Medical University  Shimotsuke Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,9,24]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140\u20106736(20)32549\u20106"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijms20184347"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0923\u20101811(02)00142\u20101"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1346\u20108138.2010.01145.x"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/1346\u20108138.14105"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/1346\u20108138.15803"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/1744666X.2019.1648209"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.2340\/00015555766871"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/1346\u20108138.16217"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1346\u20108138.1999.tb03444.x"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2021.06.008"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/1346\u20108138.14523"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/1346\u20108138.16022"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/1346\u20108138.15958"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/ijd.12070"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdin.2021.12.001"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdermsci.2014.02.006"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijms19071890"}],"container-title":["The Journal of Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1346-8138.16583","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/1346-8138.16583","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1346-8138.16583","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,19]],"date-time":"2023-08-19T19:41:36Z","timestamp":1692474096000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/1346-8138.16583"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,9,24]]},"references-count":18,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2023,1]]}},"alternative-id":["10.1111\/1346-8138.16583"],"URL":"https:\/\/doi.org\/10.1111\/1346-8138.16583","archive":["Portico"],"relation":{},"ISSN":["0385-2407","1346-8138"],"issn-type":[{"value":"0385-2407","type":"print"},{"value":"1346-8138","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,9,24]]},"assertion":[{"value":"2022-08-02","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-08-30","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-09-24","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
