Introduction: Chronic kidney disease (CKD) is an independent factor for cardiovascular system complications, such as arterial hypertension, left ventricular hypertrophy (LVH), heart failure or accelerated atherosclerosis progression. The aim of the paper was to analyze left ventricular and arterial remodeling in patients with CKD stages 1-3 to identify the subclinical marker of cardiovascular system damage which changes first in the course of CKD. Methods: The examined group consisted of 90 patients with CKD stage 1-3 and 30 subjects constituting the control group. Left ventricular mass index (LVMI), left ventricular relative wall thickness (RWT) and ejection fraction (EF) were determined by echocardiographic examination. Pulse wave velocity (PWV) between the carotid and femoral arteries as well as common carotid artery intima-media thickness (IMT) was measured. 24-h ambulatory blood pressure monitoring was performed in all subjects. Results: No differences were found between blood pressure values in the examined groups of patients with CKD1, CKD2 and CKD3. Concentric remodeling was found in 20.0%, concentric hypertrophy in 22.2% and eccentric hypertrophy in 18.9% of patients. LVMI values in patients with CKD2 and 3 were higher than in the control group. IMT values in patients with CKD3 were higher than in patients with CKD2. PWV in patients with stage 3 CKD was significantly higher than in the control group (p50.05). Conclusions: In the course of CKD, the left ventricle undergoes remodeling earlier than large arterial vessels. Echocardiographic assessment of LVH in early stages of CKD may identify patients at increased cardiovascular risk.

Arterial hypertension (AH) is one of the most common cardiovascular diseases increasing mortality rates in Poland and worldwide. Due to its prevalence, complications and treatment costs, AH is a significant health-related, economic and social problem. The aim of this study was to assess the level of acceptance of illness and compliance with therapeutic recommendations in patients with AH. The study included 200 outpatient hypertensive patients, 85 men and 115 women aged 49.1 ± 11.6, and used the standardized acceptance of illness (AIS), the eight-item Morisky Medication Adherence Scale (MMAS-8) and author’s design questionnaires. The level of acceptance of illness was found to be as follows: higher in men than in women, unaffected by comorbidities or sociodemographic factors such as residence and professional activity, decreasing with age, and correlating negatively with the duration of antihypertensive therapy. The level of adherence and compliance did not affect the AIS score and increased with the level of education. The study population demonstrated an overall good level of acceptance of illness. Men were characterized by lower levels of adherence and compliance. Patients with AH presented a moderate level of adherence and compliance, which indicates the need for providing active education, support and extensive cooperation facilitating their conformity to therapeutic recommendations.

Introduction Chronic kidney disease (CKD) is accompanied by inflammation. The aim of this study was to evaluate the effect of 6-month supplementation with omega-3 acids on selected markers of inflammation in patients with CKD stages 1–3. Methods Six-month supplementation with omega-3 acids (2 g/day) was administered to 87 CKD patients and to 27 healthy individuals. At baseline and after follow-up, blood was taken for C-reactive protein (CRP) and monocyte chemotactic protein-1 (MCP-1) concentration and white blood cell (WBC) count. Serum concentration of omega-3 acids—eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA)—was determined using gas chromatography. And 24-hour urinary collection was performed to measure MCP-1 excretion. Results After six-month omega-3 supplementation, ALA concentration increased in CKD patients and in the reference group, while EPA and DHA did not change. At follow-up, a significant decrease in urinary MCP-1 excretion in CKD (p = 0.0012) and in the reference group (p = 0.001) was found. CRP, serum MCP-1, and WBC did not change significantly. The estimated glomerular filtration rate (eGFR) did not change significantly in the CKD group. Conclusions The reduction of urinary MCP-1 excretion in the absence of MCP-1 serum concentration may suggest a beneficial effect of omega-3 supplementation on tubular MCP-1 production.
