Circadian Rhythm of Erythropoietin And Melatonin in Renal Disease

Completed
Conditions
Chronic Kidney Disease
Registration Number
NCT00698360
Lead Sponsor
Meander Medical Center
Brief Summary

Rationale: Investigation of the circadian rhythm of erythropoietin and melatonin in patients with various degrees of renal insufficiency

Objectives:

Primary objective: Is there a circadian rhythm of epo and melatonin in patients with various degrees of renal insufficiency?

Primary Objective: Is there a circadian rhythm of epo and melatonin in patients with various degrees of renal insufficiency compared to patients with a normal renal function?

Secondary Objective: Is there a circadian rhythm of cortisol and IGF in patients with various degrees of renal insufficiency?

Secondary Objective: Is there a circadian rhythm of cortisol and IGF in patients with various degrees of renal insufficiency compared to patients with a normal renal function?

Study design: Comparative study in 4 groups with various degrees of renal insufficiency, duration for each patient 24 hrs. Total duration of study 12 months, patients admitted to the hospital (on nursing ward)

Study population: Patients with various degrees of renal insufficiency

Main study parameters/endpoints: Analysis of the existence of a circadian rhythm in patients with a normal renal function and in patients with variable degrees of renal insufficiency

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Better knowledge of the circadian rhythm in renal insufficiency. This could lead to a more efficient administration of erythropoietin and melatonin in the future.

Extent of burden is 1 venapunction for placement of infusion needle, the withdrawal of 11 times 5 ml blood in 24 hrs, continuous measurement of body temperature via capsule, 24-hour continuous ambulant blood pressure monitoring.
