Abstract
Gastrointestinal (GI) tract involvement affects up to 90% of Systemic sclerosis (SSc) patients. The presence of GI symptoms is assessed by the University of California, Los Angeles, and Scleroderma Clinical Trials Consortium Gastrointestinal Scale (UCLA SCTC GIT 2.0). Microbial translocation (MT) is reported in SSc patients consequently to increased intestinal permeability due to intestinal damage (ID) and dysbiosis. Aim of this study was to assess circulating levels of LBP and EndoCab IgM (markers of MT), IL-6 (marker of inflammation), I-FABP and Zonulin (markers of ID) in a cohort of SSc patients and healthy controls (HC). Moreover, we aimed to correlate these parameters with severity of GI symptoms. UCLA SCTC GIT 2.0 questionnaire was administered to 60 consecutive SSc patients. Markers of MT, inflammation and ID were evaluated in SSc patients and HC. SSc patients had higher median value of markers of MT, inflammation and ID than HC. The logistic regression analysis showed LBP as the only variable associated with an UCLA total score "moderate-to-very severe" [OR 1.001 (CI 95%: 1.001-1.002), p < 0.001]. The logistic regression analysis showed LBP [OR 1.002 (CI 95%: 1.001-1.003), p < 0.01] and disease duration [OR 1.242 (CI 95%: 1.023-1.506), p < 0.05] as variables associated with UCLA distension/bloating "moderate-to-very severe". The logistic regression analysis showed LBP as the only variable associated with UCLA diarrhea "moderate-to-very severe" [OR 1.002 (CI 95%: 1.001-1.003), p < 0.01]. SSc patients with dysregulation gut mucosal integrity expressed by high levels of MT and ID biomarkers had more severe GI symptoms.File | Dimensione | Formato | |
