BACKGROUND: Neutrophil-related chronic inflammation (NRCI) may contribute to the pathogenesis of diabetic kidney disease (DKD). We evaluated whether blocking NRCI with low-dose colchicine prevents DKD.
METHODS: A double-blind, randomized, placebo-controlled study was conducted. A total of 160 patients with type 2 diabetes (T2D) and microalbuminuria (urinary albumin creatinine ratio [UACR] 30 to 300 mg/g Cr) who received angiotensin-converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARBs) for at least 3 months were included. Subjects were 1:1 randomized to a placebo or colchicine group (0.5 mg/day).
RESULTS: The primary end point was the incidence of overt nephropathy (UACR > 300 mg/g Cr). During the 36 months, 38 patients (51.4%) in colchicine group and 39 (54.1%) in the control group developed overt nephropathy (hazard ratio, 1.066; 95% confidence interval, 0.679-1.673; P = .78). Compared with placebo, colchicine modestly lowered levels of NRCI parameters (P values <.05 for high-sensitivity C-reactive protein, white blood cell counts, neutrophil counts, and neutrophil-to-lymphocyte ratio), whereas the changes of UACR and estimated glomerular filtration rate (eGFR) were similar between the two groups. There were no significant differences between the two groups in drug-related adverse events, including infection, gastrointestinal symptoms, and limb numbness.
CONCLUSIONS: In patients with T2D with microalbuminuria, low-dose colchicine effectively and safely lowered NRCI but did not prevent the incidence of overt nephropathy.
