Popis: Body fat has regulatory functions through producing cytokines and adipokines whose role in the pathogenesis of systemic sclerosis (SSc) is currently emerging. Changes in body mass, either over‐ or underweight, entail a dysregulation of the cytokine/adipokine network that may impact upon SSc disease activity. We evaluated serum levels of adipokines and cytokines in SSc patients and correlated them to clinical features and body mass index (BMI) categories. The study included 89 SSc patients and 26 healthy donors (HD). Serum levels of adiponectin, leptin, resistin, visfatin, tumor necrosis factor (TNF)‐α, interferon (IFN)‐γ, interleukin (IL)‐2, IL‐10 and IL‐17A were measured by multiplex immunoassay and correlated to BMI and disease‐specific features. Student’s t‐test or analysis of variance (ANOVA) were used for comparisons between groups. Spearman’s or Pearson’s tests were used for correlation analysis. Serum levels of TNF‐α, IL‐2, leptin and resistin were significantly higher in SSc than in HD. Leptin levels were significantly higher in interstitial lung disease (ILD)‐ and pulmonary arterial hypertension (PAH)‐SSc subgroups. The highest levels of IL‐17A, IL‐2, IL‐10, leptin and visfatin were detected in SSc patients with obesity (p
Adpokines and cytokines are regulated in Systemic Sclerosis across BMI categories. Leptin levels raise with BMI increase, but did not seem to be correlated with disease activity. Interestingly, TNFα levels were lowest in underweight patients suggesting its possible role in SSc associated sarcopenia.
