ABSTRACT
In recent years, there has been a progressive increase in the number of patients with chronic kidney disease (CKD), whose mortality risk is significantly higher than in general patients, which is associated with cardiovascular risks.In patients with CKD stage 5D before the start of replacement renal therapy for hypertension exceeds 90%. The aim -to analyze the efficacy and safety of the use of melatonin in the complex treatment of arterial hypertension (AH) in patients with CKD of 5 stage with impaired melatonin-forming function of the epiphysis (MFE). 60 people (35 women and 25 men) with a chronic kidney disease of 5 stage, which have violated MFE and AH were examined. For all patients in addition to antihypertensive therapy were prescribed the drug melatonin at a dose of 3 mg, which was taken once a day at 22:00 for 8 weeks. For all examined, before and after the course of treatment, were measured blood pressure (BP), Ambulatory Blood Pressure Monitoring (ABPM) and determination of the concentration of melatonin in the salivaby immunosorbent method. The examined patients showed a high frequency of MFE disturbance both in the daytime and at night - respectively, in 52,4% (p<0,001) and 82,6% (p<0,001). The dynamics of the diurnal BP on the background of treatment was due to changes in the degree of nocturnal decrease of BP, the number of patients in the main group with the "non-dipper" profile, decreased from 44,5% to 27,6% (p<0,05%), the proportion of patients with a daily profile of BP "night-peakear" from 22,4% to 4,8% (p<0,05%). Besides, a statistically significant of the number of persons with a daily profile of BP "dipper" increase in 30,2%. Against the background of complex treatment, there was a decrease in the patient's need for the dose and amount of antihypertensive drugs to achieve BP targets. Our data show a high incidence of MFE disorders in patients with CKD stage VD, and adding to the antihypertensive therapy of the drug melatonin in patients with CKD of 5 stage is effective and safe.
