Aim of the study to assess efficacy and safety of one of angiotensin II receptor blockers in patients with metabolic syndrome (MS) and I V stage chronic kidney disease. We studied cardiodynamic and renal effects of losartan in average daily dose 50 +/- 13.06 mg in 20 patients (9 men and 11 women aged 32-79 years) with MS and I V stage chronic kidney disease. Cardiodynamic effects of losartan were assessed by office blood pressure (BP) measurements, 24-hour BP monitoring (24-HBPM), echocardiography. Laboratory investigations included biochemical analysis of the blood with measurement of creatinine levels, lipid blood composition, fasting glucose, and glucose under conditions of oral glucose tolerance test. Renal function was assessed by glomerular filtration rate and microalbuminuria (MAU). Parameters of quality of life were analyzed with the use of questionnaires "Quality of life of patients with hypertensive disease" and EuroQol EQ-5D VAS thermometer. Duration of follow up was 12 weeks. 24-HBPM revealed significant lowering of systolic and diastolic BP in all temporal intervals, significant decrease of elevated diurnal systolic and diastolic BP burden, tendency to lowering of variability and normalization of 24-hour BP profile. We also noted tendency to lowering of MAU from 5.60 mg/dl (median) (3.50; 9.20 [25(th) and 75(th) percentile]) to 3.25 mg/dl (0.40; 7.83); significant lowering of levels of triglycerides and glucose under conditions of glucose tolerance test; improvement of parameters characterizing quality of life namely reduction of integral assessment by the "Quality of life of patients with hypertensive disease" questionnaire and improvement of EQ-5D VAS (thermometer) score related to arterial hypertension. We conclude that losartan in patients with MS and early signs of impairment of kidney function in addition to antihypertensive action exerts favorable effect on parameters of 24-hour BP profile, has good safety profile, causes favorable metabolic effects, lowers level of MAU and improves parameters of quality of life.
