Abstract

Background & aims Melatonin may benefit diabetic people with coronary heart disease (CHD) through its beneficial effects on biomarkers of oxidative stress and cardio-metabolic risk. This investigation evaluated the effects of melatonin administration on metabolic status in diabetic patients with CHD.Methods This randomized, double-blind, placebo-controlled trial was conducted and involved 60 diabetic patients with CHD. Subjects were randomly allocated into two groups to receive either 10 mg melatonin (2 melatonin capsules, 5 mg each) (n = 30) or placebo (n = 30) once a day for 12 weeks.Results Compared with the placebo, melatonin supplementation resulted in significant increases in plasma glutathione (GSH) (+64.7 ± 105.7 vs. -11.1 ± 137.6 μmol/L, P = 0.02) and nitric oxide (NO) (+0.9 ± 4.7 vs. -3.3 ± 9.6 μmol/L, P = 0.03), and significant decreases in malondialdehyde (MDA) (-0.2 ± 0.3 vs. +0.1 ± 0.5 μmol/L, P = 0.007), protein carbonyl (PCO) (-0.12 ± 0.08 vs. +0.03 ± 0.07 mmol/mg protein, P < 0.001) and serum high sensitivity C-reactive protein (hs-CRP) levels (-1463.3 ± 2153.8 vs. +122.9 ± 1230.4 ng/mL, P = 0.001). In addition, taking melatonin, compared with the placebo, significantly reduced fasting plasma glucose (-29.4 ± 49.0 vs. -5.5 ± 32.4 mg/dL, P = 0.03), serum insulin concentrations (-2.2 ± 4.1 vs. +0.7 ± 4.2 μIU/mL, P = 0.008), homeostasis model of assessment-estimated insulin resistance (-1.0 ± 2.2 vs. +0.01 ± 1.6, P = 0.04), total-/HDL-cholesterol ratio (-0.18 ± 0.38 vs. +0.03 ± 0.35, P = 0.02) and systolic (-4.3 ± 9.6 vs. +1.0 ± 7.5 mmHg, P = 0.01) and diastolic blood pressure (-2.8 ± 7.3 vs. +0.1 ± 3.6 mmHg, P = 0.04). Melatonin treatment also significantly increased quantitative insulin sensitivity check index (+0.006 ± 0.01 vs. -0.004 ± 0.01, P = 0.01) and serum HDL-cholesterol (+2.6 ± 5.5 vs. -0.01 ± 4.4 mg/dL, P = 0.04). Supplementation with melatonin had no significant effect on other metabolic parameters.Conclusions Overall, melatonin intake for 12 weeks to diabetic patients with CHD had beneficial effects on plasma GSH, NO, MDA, PCO, serum hs-CRP levels, glycemic control, HDL-cholesterol, total-/HDL-cholesterol ratio, blood pressures and parameters of mental health.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
