Study summary

The aim of this double-blind randomized clinical trial is to determine the effects of Melatonin on cardiovascular disease risk factors, bone metabolism markers, serum concentrations of advanced glycated end products and quality of life in peritoneal dialysis patients. Forty patients from peritoneal dialysis centers will randomly assign to either Melatonin or placebo group. The patients in Melatonin group will receive 5 mg Melatonin (as 1 tablet) daily for 10 weeks, while the placebo group will receive identical placebo. At the baseline and the end of the study,7 ml blood will be collected from each patient after a 12-14-hours fasting and Serum concentrations of malondialdehyde; high sensitivity c-reactive protein; Soluble intercellular adhesion molecule-1; glucose; pentosidine; carboxy-methyl lysine; Procollagen 1 Intact N-Terminal Propeptide; Tartrate-resistant acid phosphatase 5b; osteoprotegerin; Receptor activator of nuclear factor kappa-Β ligand; Intact parathyroid hormone; triglyceride; total cholesterol; High-density lipoprotein cholesterol; low-density lipoprotein cholesterol; lipoprotein-a; albumin; calcium; phosphorous; and also systolic blood pressure; diastolic blood pressure and questionnaires including quality of life; quality of sleep and depression will be assessed.

Inclusion criteria

  • Continuous Ambulatory Peritoneal Dialysis for 6 months or more
  • (BMI) below 35

Exclusion criteria

Exclusion Criteria:

  • Infectious diseases (especially peritonitis) and inflammatory diseases Liver diseases
  • Past medical history of cancer Receiving drugs, non-steroidal anti-inflammatory drugs
  • Receiving Melatonin supplements
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
