Design outcomes

Primary

MeasureTime frame
Main Objective: To assess changes in inflammatory cytokine release of monocytes and neutrophils stimulated with cholesterol crystals, isolated from patients with chronic coronary artery disease after colchicine 0.5mg daily during one month, compared to no colchicine treatment;Secondary Objective: Secondary objective: To assess whether hsCRP change in serum correlates with change in cytokine release by monocytes and neutrophils stimulated with MSU crystals, isolated from patients with chronic coronary artery disease after colchicine 0.5mg daily during one month Tertiary objective: To assess changes of RNA expression in CD14+ monocytes, isolated from patients with chronic coronary artery disease after colchicine 0.5mg daily during one month, compared to no colchicine treatment. ;Primary end point(s): The change in inflammatory cytokine release of monocytes and neutrophils, after stimulation with MSU crystals, isolated before versus after treatment with low dose colchicine of 0.5mg daily during one month, compared to no colchicine treatment;Timepoint(s) of evaluation of this end point: One month after treatment with colchicine

Secondary

MeasureTime frame
Secondary end point(s): Secondary objective: Correlation between change in serum hsCRP and change in cytokine release of monocytes and neutrophils after stimulation with MSU crystals after one month of colchicine treatment 0.5mg once daily Tertiary objective: Changes in RNA expression in CD14+ monocytes, isolated from patients with chronic coronary artery disease before versus after colchicine 0.5mg daily during one month, compared to no colchicine treatment. ;Timepoint(s) of evaluation of this end point: One month after treatment with colchicine
