Brief Summary

Modern living is associated with an epidemic of type 2 diabetes mellitus (T2DM). Sleep disturbances such as insomnia or frequent awakenings are strong risk factors for T2DM with several studies indicating a central role of melatonin. Additionally, a certain single nucleotide polymorphism in the melatonin receptor gene, MTNR1B rs10830963, with an allele frequency of 30 %, is associated with increased fasting plasma glucose and T2DM. Due to treatment of, among other things, insomnia, the use of melatonin is increasing rapidly in Denmark with a 100-fold increase from 2007-2012 in children and adolescents. No previous studies have thoroughly assessed changes in glucose and fatty acid metabolism after 3 months of melatonin treatment in patients with T2DM.

Outcome Measures

Primary Outcomes (4)

  • Change of insulin sensitivity

    Insulin sensitivity is assessed by a hyperinsulinemic euglycemic clamp, unit: mg/kg/min (mg of glucose to maintain euglycemia per kilogram of weight per minuts)

    The outcome will be measured after 3 months of placebo treatment and after 3 months of melatonin treatment and compared afterwards with a paired T-tes

  • Change of insulin secretion change

    Insulin secretion is assessed by an intravenous glucose tolerance test, unit: pmol/L (insulin)

    The outcome will be measured after 3 months of placebo treatment and after 3 months of melatonin treatment

  • MTNR1a rs10830963 influence on change in insulin sensitivity and insulin secretion

    MTNR1a rs10830963 genotype influence on insulin sensitivity and insulin secretion (see outcome 1 + 2)

    The outcome will be measured after 3 months of placebo treatment and again after 3 months of melatonin treatment

  • Change of insulin signalling

    Insulin signalling in muscle and adipose tissue assessed by western blot

    The outcome will be measured after 3 months of placebo treatment and after 3 months of melatonin treatment

Secondary Outcomes (13)

  • Change of ambulatory blood pressure

    The outcome will be measured after 3 months of placebo treatment and after 3 months of melatonin treatment

  • Change of arterial stiffness

    The outcome will be measured after 3 months of placebo treatment and after 3 months of melatonin treatment

  • Change of gut microbiome

    The outcome will be measured after 3 months of placebo treatment and after 3 months of melatonin treatment

  • Change of sleep evaluation 1

    The outcome will be measured after 3 months of placebo treatment and after 3 months of melatonin treatment

  • Change of sleep evaluation 2

    After 3 months treatmentThe outcome will be measured after 3 months of placebo treatment and after 3 months of melatonin treatment

  • +8 more secondary outcomes
