Abstract
Background
Patients with type 2 diabetes face an increased risk of cardiovascular disease (CVD), partly due to a prothrombotic state with increased platelet reactivity. Colchicine, an anti-inflammatory drug, has shown promise in reducing cardiovascular events, but its effects on platelet function remain unclear. This trial evaluated the effect of low-dose colchicine on platelet aggregation and platelet activation indices in patients with type 2 diabetes.
Methods
In this double-blind, randomized, placebo-controlled trial, 100 participants with type 2 diabetes and previous CVD or a least one cardiovascular risk factor were randomized in a 1:1 ratio to receive either colchicine (0.5 mg/day) or placebo for 26 weeks. Platelet aggregation was assessed using multiple electrode aggregometry expressed as aggregation units (AU) × minutes (mins). Adenosine diphosphate (ADP), arachidonic acid (AA), and thrombin-receptor-activating peptide (TRAP) were used as agonists.
Results
A total of 95 participants completed the trial. After 26 weeks, no significant differences were observed between the colchicine and placebo groups in platelet aggregation induced by ADP (ΔADP-aggregation: 49, 95 % CI: −15;113 AU x mins, p = 0.08), AA (ΔAA-aggregation: −4, 95 % CI: −24;16 %, p = 0.69), or TRAP (ΔTRAP-aggregation: −3, 95 % CI: −11;4 %, p = 0.39). Similarly, no between-group differences were found in platelet parameters, including platelet count mean platelet volume, and immature platelet fraction.
Conclusions
Low-dose colchicine did not significantly alter platelet aggregation or platelet activation indices in patients with type 2 diabetes. These findings suggest that colchicine's cardioprotective effects are not mediated through direct effects on platelet function.
期刊介绍:
Journal of Diabetes and Its Complications (JDC) is a journal for health care practitioners and researchers, that publishes original research about the pathogenesis, diagnosis and management of diabetes mellitus and its complications. JDC also publishes articles on physiological and molecular aspects of glucose homeostasis.
The primary purpose of JDC is to act as a source of information usable by diabetes practitioners and researchers to increase their knowledge about mechanisms of diabetes and complications development, and promote better management of people with diabetes who are at risk for those complications.
Manuscripts submitted to JDC can report any aspect of basic, translational or clinical research as well as epidemiology. Topics can range broadly from early prediabetes to late-stage complicated diabetes. Topics relevant to basic/translational reports include pancreatic islet dysfunction and insulin resistance, altered adipose tissue function in diabetes, altered neuronal control of glucose homeostasis and mechanisms of drug action. Topics relevant to diabetic complications include diabetic retinopathy, neuropathy and nephropathy; peripheral vascular disease and coronary heart disease; gastrointestinal disorders, renal failure and impotence; and hypertension and hyperlipidemia.
