Úloha zánětu v patologické kostní resorpci u axiální spondyloartritidy

Šebová, Eva

Introduction: Axial spondyloarthritis (ax-SpA) is an inflammatory rheumatic disease. It is a unique model of bone remodeling disorders because, although one of the main diagnostic parameters is the rate of bone formation, inflammation present in patients' bodies increases the risk of pathological bone resorption, which can lead to osteoporosis. The processes of pathological resorption in ax-SpA have not been fully investigated, both in the disease as such and in the individual forms of the disease, i.e. non-radiographic (nr-axSpA), radiographic axial spondyloarthritis (r-axSpA) and ankylosing spondylitis (AS). This work deals with the influence of inflammatory serum of patients on the process of osteoclast differentiation from peripheral precursors of patients and healthy donors. Material and methods: Monocytes separated from the peripheral blood of either axSpA patients or healthy donors were stimulated for 14 days in vitro with serum from patients and in parallel with serum of age and sex of the corresponding healthy donors. Osteoclasts were evaluated as multinucleated, TRAP positive cells. Their numbers were statistically processed. Results: The inflammatory serum environment of patients with axSpA stimulated the osteoclastogenesis of axSpA monocytes significantly more (P <0,05) than the...
