Although a peerless therapy among moderate to severe types of psoriasis, the therapeutic effectiveness of biological therapy may vary unforeseeably between patients and leads to biologics switch. We conducted a pilot study in patients diagnosed with psoriasis and treated with biologics, the purpose of which was to explore the prevalence of suboptimal states of vitamin D, especially in the group of patients characterized by the failure of previous biologics, and to investigate the associations between vitamin D levels and psoriasis, regarding aspects such the severity of the disease and quality of life. Their current result of latent tuberculosis infection (LTBI) was also considered concerning a feasible relationship with vitamin D levels. From July to December 2021, 45 patients corresponding to our inclusion criteria were assessed. Variables such as Psoriasis Area and Severity Index (PASI) score and the Dermatology Life Quality Index (DLQI) score, as well as vitamin D serum concentrations and their LTBI result, were recorded for them. Lower serum concentrations of vitamin D were not more common in patients characterized by failure to previous biologics (p = 0.443), but we concluded a weak correlation between the DLQI score and vitamin D (rho = \u22120.345, p-value = 0.020), although a statistically insignificant result was obtained between vitamin D and the PASI score (rho = \u22120.280, p-value = 0.062), and with the LTBI result (rho = \u22120.053, p-value = 0.728). These results establish a connection between higher levels of vitamin D and a better outcome of psoriasis from the perspective of the patient\u2019s quality of life, with no significant association with psoriasis severity and no significant prevalence of suboptimal states among patients that failed previous biologics compared to those with a continuously good response.<\/jats:p>","DOI":"10.3390\/jpm12111857","type":"journal-article","created":{"date-parts":[[2022,11,8]],"date-time":"2022-11-08T08:52:56Z","timestamp":1667897576000},"page":"1857","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Vitamin D May Be Connected with Health-Related Quality of Life in Psoriasis Patients Treated with Biologics"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8258-6989","authenticated-orcid":false,"given":"Iulia-Alexandra","family":"Paliu","sequence":"first","affiliation":[{"name":"Department of Pharmacology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simona-Laura","family":"Ianosi","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1374-276X","authenticated-orcid":false,"given":"Adina","family":"Turcu-Stiolica","sequence":"additional","affiliation":[{"name":"Department of Pharmacoeconomics, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catalina-Gabriela","family":"Pisoschi","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luminita-Georgeta","family":"Predoi","sequence":"additional","affiliation":[{"name":"Dermatology Ambulatory Office, Clinical Emergency County Hospital of Craiova, 200642 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrei-Adrian","family":"Tica","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1111\/jdv.13854","article-title":"A systematic review of worldwide epidemiology of psoriasis","volume":"31","author":"Michalek","year":"2017","journal-title":"J.
