Abstract


Introduction & Aim: The collection of microbes and their genes that exist within and on the human body, collectively known as the microbiome has emerged as a principal factor in variety of disease states. Humans and microbes have established a symbiotic association over time and perturbations in this association have been linked to several immune-mediated inflammatory diseases. Therefore, enteric microbiota dysbiosis with gut barrier disruption may be important factor in the development of psoriasis. The aim of the study was to analyse the intestinal barrier integrity in psoriasis. Materials & Methods: We determined concentrations of gut barrier integrity markers: claudin-3 (tight junction protein), intestinal fatty acid binding protein (I-FABP; endogenous enterocyte protein), in the blood plasma of patients with chronique plaque psoriasis (n=30) and healthy individuals (n=30). Claudin-3 and I-FABP were measured using commercially available ELISA test kits. Results: Claudin-3 concentration was higher in patients with psoriasis compared with healthy control (median: 54.07 ng/ ml vs. 42.36 ng/ml; p<0.001). Patients with psoriasis had also elevated concentration of plasma I-FABP (median 708.8 pg/ ml vs. 147.1 pg/ml p<0.05). Concentrations of claudin-3 and I-FABP significantly correlated with disease activity assessed by psoriasis area and severity index. Conclusion: Our results support the hypothesis that dysfunction of intestinal barrier disturbs the homeostatic equilibrium between the microbiota and immune system that may result in chronic systemic inflammation. Many critical questions remain to be answered before we can apply new knowledge to improve therapeutic interventions in psoriasis.
