Lipid profile disturbances and upregulation of enzymes crucial for fatty acid oxidation have been reported in patients with psoriasis. Mitochondrial \u00df\u2010oxidation is altered in patients with IR. Common mitochondrial dysfunction may be involved in the origin of both diseases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>This study aimed to evaluate mitochondrial \u00df\u2010oxidation, intermediary metabolism, and mitochondrial content in psoriatic patients with or without IR and compare them to healthy controls.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The participants were divided into three groups: (1) psoriasis and IR (<jats:italic>n<\/jats:italic>\u00a0=\u00a026); (2) psoriasis without IR (<jats:italic>n<\/jats:italic>\u00a0=\u00a017); and (3) healthy controls (<jats:italic>n<\/jats:italic>\u00a0=\u00a017). Quantification of amino acids and acylcarnitines (AC) by tandem mass spectrometry, determination of urinary organic acids by gas chromatography\/mass spectrometry (GC\/MS), and mitochondrial DNA quantification were performed in all groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>When comparisons were made between the two psoriatic groups, no differences were found between: C5DC\u2009+\u2009C6OH, C16:1, Met\/Leu, Met\/Phe, C16:1\/C16, and C5DC\u2009+\u2009C6OH\/C4DC\u2009+\u2009C5OH ratios. Nine analytes were different: phenylalanine, Cit\/Phe, and Cit\/Tyr ratios, C0, C3, C5, C6DC, C16, and C18:1OH. There were no correlations between psoriasis area and severity index (PASI), body mass index (BMI) and duration of disease with ACs. A higher proportion of patients with psoriasis showed increased urine levels of uric acid and hippuric acid (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.01). The mtDNA content was significantly higher in cases than in controls, with no differences between IR and non\u2010IR psoriatic patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Psoriasis patients with and without IR have a different acylcarnitine profile reflecting impaired \u00df\u2010oxidation. A distinctive profile of acylcarnitines suggests an involvement of mitochondrial function associated with an increase in stearoyl CoA desaturase (SCD) activity in psoriatic patients with and without IR.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jdv.18631","type":"journal-article","created":{"date-parts":[[2022,10,3]],"date-time":"2022-10-03T06:18:11Z","timestamp":1664777891000},"page":"340-347","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Mitochondrial dysfunction: The pathological link between psoriasis and insulin resistance?"],"prefix":"10.1111","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4783-3793","authenticated-orcid":false,"given":"Alejandra","family":"Villarreal\u2010Martinez","sequence":"first","affiliation":[{"name":"Servicio de Dermatolog\u00eda, Hospital Universitario \u201cDr. Jos\u00e9 E.
