ABSTRACT: AIMS:Inflammation plays a pivotal role in atherothrombosis. Colchicine is an anti-inflammatory drug that may attenuate this process. Cardiovascular protective effects of anti-inflammatory drugs, however, seem to be limited to patients with a biochemical response. We therefore investigated whether short-term exposure to colchicine reduced inflammatory markers and whether additional laboratory changes occur in patients with chronic coronary artery disease. METHODS & RESULTS:In 138 consecutive patients with chronic coronary artery disease and a high sensitivity C-reactive Protein (hs-CRP) ? 2 mg/L, inflammatory markers, lipids, haematologic parameters and renal function were measured at baseline and after 30 days exposure to colchicine 0.5mg once daily. Hs-CRP decreased from baseline 4.40 mg/L (interquartile range [IQR] 2.83-6.99 mg/L) to 2.33 mg/L (IQR 1.41-4.17, median of the differences -1.66 mg/L, 95% confidence interval [CI] -2.17 - -1.22 mg/L, p-value <0.01), corresponding to a median change from baseline of -40%. Interleukin-6 decreased from 2.51 ng/L (IQR 1.59-4.32 ng/L) to 2.22 ng/L (median of the differences -0.36 ng/L, 95%CI -0.70 - -0.01 ng/L, p-value 0.04), corresponding to a median change from baseline of -16%. No clinically relevant changes in lipid fractions were observed. Both leukocyte and thrombocyte count decreased (median change from baseline -7% and -4% respectively). Estimated glomerular filtration rate decreased with a mean change from baseline of -2%. CONCLUSION:In patients with chronic coronary artery disease and elevated hs-CRP, one-month exposure to colchicine 0.5 mg once daily was associated with a reduction of inflammatory markers. A small effect was seen on white blood cell count and platelet count, as well as a small decrease in estimated glomerular filtration rate.
