Inflammation Clinical Trial
Official title:
The Role of Pyroptosis in Chronic Venous Disease and Its Pathophysiological Implication
Enrollment criteria and clinical data collection: following the principles of medical ethics, the development of inclusion and exclusion criteria. Selecting 200 cases of chronic venous disease (CVD) according to the Comprehensive Classification System for Chronic Venous Disorders (CEAP) divided into 6 Clinical stages (C1-C6) (Group A). Selecting 200 healthy participants without CVD (C0) as controls (Group B). Blood samples will be collected from both groups. Markers of pyroptosis (NETs, Caspase-1 and Cytokines) will be evaluated between the two groups and between the subgroups, according to clinical stage, in group A.
Pyroptosis is a pro-inflammatory form of regulated cell death and is dependent on networks of
extracellular fibers (NET,s), on the enzymatic activity of inflammatory proteases that belong
to the family of cysteine-dependent aspartate-specific proteases (caspase), and cytokines.
The role of inflammation has been previously demonstrated in chronic venous disease (CVD),
which is a condition that affects up to 80% of adult population in western countries.
According to the Comprehensive Classification System for Chronic Venous Disorders (CEAP)
divided into 6 Clinical stages:
C0: no visible or palpable signs of venous disease. C1: telangiectasies or reticular veins.
C2: varicose veins. C3: edema. C4a: pigmentation and eczema. C4b: lipodermatosclerosis and
atrophie blanche. C5: healed venous ulcer. C6: active venous ulcer.
The aim of this study is to evaluate the role of pyroptosis in the onset and progression of
CVD.
The Investigators will select 200 participants with chronic venous disease (CVD) according to
Clinical stage of CEAP (C1-C6 patients) [Group A] . The investigators will also select 200
healthy participants without CVD (C0) as controls [Group B].
Peripheral vein blood samples will be collected from both groups. Markers of pyroptosis
(NETs, Caspase-1 and Cytokines) will be evaluated between the two groups and between the
subgroups of group A, according to clinical stage.
