Aims: Cardiothrophin-1 (CT-1) is a novel 201 amino acid cytokine that has pleiotropic protective effects in apoptosis, hepatic injury, myocardial infection and contrast nephropathy. CT-1 predicts a variety of disorders including atherosclerosis, heart failure, hypertension and cardiomyopathy. However, CT-1 has not been studied previously in diabetic patients without heart failure. The aim of this study was, therefore, to compare CT-1 levels in diabetic and non-diabetic patients. Methods: Thirty-eight patients with type 2 diabetes mellitus and 32 non-diabetic controls have been enrolled into the study. Subjects with severe hypertension, renal diseases, pregnancy and malignancy were excluded. The statistical analysis was performed with SPSS for Windows version 15.0. Results: There were no significant differences between the diabetic and non-diabetic groups with regard to age, hypertension, serum creatinine, systolic and diastolic blood pressure. Median plasma CT-1 was 9.05 (5.70-24.94) pg/ml in diabetic group and 7.16 (5.53-9.64) pg/ml in non-diabetic group (P<0.001). Conclusion: Plasma CT-1 levels increased in diabetic patients independently of hypertension (HT) and heart failure. Prospective studies with a larger cohort are now needed to observe the effects of CT-1 treatment in a diabetic population.
