Diseases accompanying psoriasis include metabolic and cardiovascular disorders. It has been suggested that inflammation is involved in the development of each of these conditions. The main objective of this study was to analyse the fatty acid profile, including polyunsaturated fatty acids, in the erythrocyte membranes of patients suffering from psoriasis. A total of 58 adult patients of the Department of Skin and Venereal Diseases of the Pomeranian Medical University in Szczecin, suffering from psoriasis, were qualified for this study. The patients had undergone an interview and physical examination, during which the severity of psoriasis was assessed. All patients had their weight and height measured to assess their body mass index (BMI). After 3 months of treatment, biochemical parameters (ALT, AST, total cholesterol) and inflammatory markers (CRP) in the blood were assessed. In addition, the isolation of fatty acids (PUFAs, SFAs, MUFAs) from erythrocyte membranes and the qualitative and quantitative analysis of their profile using a gas chromatograph were carried out. In patients with severe psoriasis requiring systemic treatment, an altered profile of fatty acids in erythrocyte membranes was found, including a significantly lower concentration of polyunsaturated fatty acids (omega-3), which have an anti-inflammatory effect; a significantly higher concentration of saturated fatty acids; and a decreased concentration of oleic acid (omega-9), compared to the results obtained in patients with less severe psoriasis receiving topical treatment. In patients with psoriasis and BMI \u2265 25, significantly higher concentrations of AST and ALT in the blood and significantly higher concentrations of pro-inflammatory arachidonic acid in erythrocyte membranes were found. Elevated concentrations of saturated (R = 0.31) and monounsaturated fatty acids (R = 0.29) may correlate with a greater severity of psoriasis.<\/jats:p>","DOI":"10.3390\/nu16121799","type":"journal-article","created":{"date-parts":[[2024,6,7]],"date-time":"2024-06-07T10:43:42Z","timestamp":1717757022000},"page":"1799","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Fatty Acid Profile of Erythrocyte Membranes in Patients with Psoriasis"],"prefix":"10.3390","volume":"16","author":[{"given":"Mariola","family":"Marchlewicz","sequence":"first","affiliation":[{"name":"Department of Dermatology and Venereology, Faculty of Health Sciences, Pomeranian Medical University, 71-210 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zofia","family":"Polakowska","sequence":"additional","affiliation":[{"name":"Department of Aesthetic Dermatology, Faculty of Health Sciences, Pomeranian Medical University, 70-111 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2293-6489","authenticated-orcid":false,"given":"Dominika","family":"Maciejewska-Markiewicz","sequence":"additional","affiliation":[{"name":"Department of Human Nutrition and Metabolomics, Pomeranian Medical University, 71-460 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ewa","family":"Stachowska","sequence":"additional","affiliation":[{"name":"Department of Human Nutrition and Metabolomics, Pomeranian Medical University, 71-460 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9014-727X","authenticated-orcid":false,"given":"Natalia","family":"Jakubiak","sequence":"additional","affiliation":[{"name":"Department of Human Nutrition and Metabolomics, Pomeranian Medical University, 71-460 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"Kiedrowicz","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Venereology, Faculty of Health Sciences, Pomeranian Medical University, 71-210 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandra","family":"Rak-Za\u0142uska","sequence":"additional","affiliation":[{"name":"Department of Aesthetic Dermatology, Faculty of Health Sciences, Pomeranian Medical University, 70-111 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micha\u0142","family":"Duchnik","sequence":"additional","affiliation":[{"name":"Department of General and Vascular Surgery, Public Voivodeship Combined Hospital, 70-891 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-2429-5150","authenticated-orcid":false,"given":"Alicja","family":"Wajs-Syrenicz","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Venereology, Faculty of Health Sciences, Pomeranian Medical University, 71-210 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ewa","family":"Duchnik","sequence":"additional","affiliation":[{"name":"Department of Aesthetic Dermatology, Faculty of Health Sciences, Pomeranian Medical University, 70-111 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"50","DOI":"10.15420\/ecr.2018.33.1","article-title":"The Role of Inflammation in Diabetes: Current Concepts and Future Perspectives","volume":"14","author":"Tsalamandris","year":"2019","journal-title":"Eur.
