They are associated with increased incidence, prevalence and severity of the disease. A positive effect of weight loss on psoriasis activity has been shown in several studies. Obesity-related factors such as the dysregulation of glucose and lipid metabolism, the activation of adipose tissue and resultant persistent low-grade inflammation have been discussed as links of obesity and inflammatory diseases. Recently, we demonstrated a critical role of free fatty acids (FFAs) in obesity-mediated exacerbation of psoriatic skin inflammation in both mice and humans. In the present study, we translated these findings into a therapeutic intervention. An open-label study focusing on the dietary reduction of FFAs was conducted in patients with mild-to-moderate plaque psoriasis, and disease severity and serum markers of inflammation were analyzed. Here, we show that such a dietary intervention improves psoriatic disease activity independently of weight loss. Diet-related metabolic changes, such as a reduction in saturated free fatty acids (SFAs), may thus be more important than weight loss itself. Moreover, dietary intervention inhibited the overall pro-inflammatory activation status in patients, as shown by analysis of serum inflammatory parameters using the Olink platform. From our pilot study, we conclude that dietary intervention focusing on SFA reduction has the capacity to reduce disease activity and general inflammatory status in psoriasis patients.<\/jats:p>","DOI":"10.3390\/nu15071698","type":"journal-article","created":{"date-parts":[[2023,3,31]],"date-time":"2023-03-31T05:37:02Z","timestamp":1680241022000},"page":"1698","source":"Crossref","is-referenced-by-count":0,"title":["Modulation of Dietary Fatty Acids in an Open-Label Study Improves Psoriasis and Dampens the Inflammatory Activation Status"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-1084-3875","authenticated-orcid":false,"given":"Anja","family":"Saalbach","sequence":"first","affiliation":[{"name":"Department of Dermatology, Venerology and Allergology, Faculty of Medicine, Leipzig University, Philipp Rosenthal Str. 23, 04103 Leipzig, Germany"}]},{"given":"Anna-Theresa","family":"Seitz","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Venerology and Allergology, Faculty of Medicine, Leipzig University, Philipp Rosenthal Str. 23, 04103 Leipzig, Germany"}]},{"given":"Johannes","family":"Kohlmann","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Venerology and Allergology, Faculty of Medicine, Leipzig University, Philipp Rosenthal Str. 23, 04103 Leipzig, Germany"}]},{"given":"Lena","family":"Kalweit","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Venerology and Allergology, Faculty of Medicine, Leipzig University, Philipp Rosenthal Str. 23, 04103 Leipzig, Germany"}]},{"given":"Lisa","family":"Vogt","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Venerology and Allergology, Faculty of Medicine, Leipzig University, Philipp Rosenthal Str. 23, 04103 Leipzig, Germany"}]},{"ORCID":"http:\/\/orcid.org\/0009-0009-2003-5247","authenticated-orcid":false,"given":"Lars","family":"Selig","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Nutritional Medicine, Faculty of Medicine, Leipzig University, 04103 Leipzig, Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-0611-7042","authenticated-orcid":false,"given":"Kathrin M.","family":"Engel","sequence":"additional","affiliation":[{"name":"Institute of Medical Physics and Biophysics, Faculty of Medicine, Leipzig University, 04107 Leipzig, Germany"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-5238-0063","authenticated-orcid":false,"given":"Jan C.","family":"Simon","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Venerology and Allergology, Faculty of Medicine, Leipzig University, Philipp Rosenthal Str. 23, 04103 Leipzig, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"253","DOI":"10.1016\/S2213-8587(22)00033-X","article-title":"Body-Mass Index and Risk of Obesity-Related Complex Multimorbidity: An Observational Multicohort Study","volume":"10","author":"Strandberg","year":"2022","journal-title":"Lancet Diabetes Endocrinol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"eaba2907","DOI":"10.1126\/scitranslmed.aba2907","article-title":"Weighing in on Asthma","volume":"12","author":"Brunner","year":"2020","journal-title":"Sci.
