Introduction Atherosclerosis is a major risk factor for increased cardiovascular morbidity and mortality in dialysis patients. First clinical symptoms are usually associated with initial atherosclerotic changes of blood vessels. The aim of this study was ultrasound evaluation of intimae media thickness (IMT) of carotid arteries in dialysis patients and its correlation with certain risk factors. Patients and methods IMT was measured in 45 dialysis patients with no signs of cardiovascular diseases:15 continuous ambulatory peritoneal dialysis (CAPD) patients, 30 haemodialysis (HD) patients and in 20 healthy controls. IMT was correlated with certain risk factors for atherosclerosis (general parameters - age, gender, duration of dialysis cause of renal diseases, parameters of nutrition, parameters of calcium and phosphorus metabolism, lipid parameters, blood pressure and smoking). Results The mean carotid artery IMT was significantly higher in dialysis patients than in the control group (p<0.05). In addition, the mean IMT was statistically significantly higher in PD than in HD patients (p<0.05). In CAPD patients there was a significant correlation between IMT and total and LDL cholesterol. In the second group (HD patients) IMT was significantly correlated with diastolic blood pressure, BMI and smoking. Conclusion Although atherosclerotic cardiovascular disease may not manifest in dialysis patients, IMT of carotid arteries significantly increases. Major risk factors affecting IMT are lipid disturbances in patients on peritoneal dialysis and hypertension, obesity and smoking in HD patients.

The Mean

Background Potential risk factors for 1-year mortality, including the peritoneal component of dialysis dose, residual renal function, demographic data, hematocrit, serum albumin, dialysate-to-plasma creatinine ratio, and blood pressure, were examined in a national cohort of peritoneal dialysis patients randomly selected for the Centers for Medicare and Medicaid Services End-Stage Renal Disease (ESRD) Core Indicators Project. Methods The study involved retrospective analysis of a cohort of 1219 patients receiving chronic peritoneal dialysis who were alive on December 31, 1996. Results During the 1-year follow-up period, 275 patients were censored and 200 non censored patients died. Among the 763 patients who had at least one calculable adequacy measure, the mean [± standard deviation (SD)] weekly Kt/V urea was 2.16 ± 0.61 and the mean weekly creatinine clearance was 66.1 ± 24.4 L/1.73 m2. Excluding the 365 patients who were anuric, the mean (±SD) urinary weekly Kt/V urea was 0.64 ± 0.52 (median: 0.51) and the mean (±SD) urinary weekly creatinine clearance was 31.0 ± 23.3 L/1.73 m2 (median: 26.3 L/1.73 m2). By Cox proportional hazard modeling, lower quartiles of renal Kt/V urea were predictive of 1-year mortality; lower quartiles of renal creatinine clearance were of borderline significance for predicting 1-year mortality. The dialysate component of neither the weekly creatinine clearance nor the weekly Kt/V urea were predictive of 1-year mortality. Other predictors of 1-year mortality ( p < 0.01) included lower serum albumin level, older age, and the presence of diabetes mellitus as the cause of ESRD, and, for the creatinine clearance model only, lower diastolic blood pressure. Conclusion Residual renal function is an important predictor of 1-year mortality in chronic peritoneal dialysis patients.

Atherosclerosis is significant risk factor for cardiovascular morbidity and mortality in dialysis patients. Aim of the study was ultrasound evaluation of intima media thickness on carotid arteries (as a marker of atherosclerosis), in dialysis patients and its correlation with proposed risk factors. Intima media thickness was measured in 45 dialysis patients with no signs of cardiovascular diseases (15 on peritoneal dialysis, group I,30 on hemodialysis, group II) and 20 healthy controls. The mean carotid artery intima media thickness was significantly higher in dialysis patients than in control group. According to intima media thickness, dialysis patients were divided in group A (patient with intima media thickness less or equal 0,720 mm) and group B (intima media thickness higher then 0,720mm). Intima media thickness in bout group was correlated with proposed risk factors. In group A there was not significant correlation of intima media thickness with risk factors. In group B significant correlation have been found between intima media thickness and LDL, VLDL cholesterol, body mass index and systolic, diastolic and mean blood pressure. Although atherosclerosis was not the only cause for cardiovascular morbidity and mortality, it has a dominant role in dialysis patients. Augmented intima media thickness could be early marker of atherosclerosis. The risk factors of great influence on intima media thickness are lipid disturbances, obesity and hypertension.

Cardiovascular (CVS) morbidity and mortality in the endstage renal disease (ESRD) patients on peritoneal dialysis therapy is 10-30 folds higher than in general population. The prevalence of well known traditional risk factors such as age, sex, race, arterial hypertension, hyperlipidaemia, diabetes, smoking, physical inactivity is higher in the uraemic patients. Besides these, there are specific, nontraditional risk factors for dialysis patients. Mild inflammation present in peritoneal dialysis (PD) patients which can be confirmed by specific inflammatory markers is the cause of CVS morbidity and mortality in these patients. Hypoalbuminaemia, hyperhomocysteinaemia and a higher level of leptin are important predictors of vascular complications as well as CVS events in the PD patients. Plasma norepinephrine, an indicator of sympathetic activity, is high in the ESRD patients and higher in the PD patients than in the patients on haemodialysis (HD). Therefore, norepinephrine may be a stronger risk factor in the PD patients. The same applies to asymmetric dimethylargine (ADMA), an endogenous inhibitor of nitric oxide synthase, which is an important risk factor of CVS morbidity and mortality 15 % higher in the PD than the HD patients. Hyperphosphataemia, secondary hyperparathyroidism and high calcium x phosphate product have been associated with the progression of the coronary artery calcification and valvular calcifications and predict all-cause CVS mortality in the PD patients. Residual renal function (RRF) declines with time on dialysis but is slower in the PD than the HD patients. RRF decline is associated with the rise of proinflammatory cytokines and the onset of hypervolaemia and hypertension which increase the risk of CVS diseases, mortality in general and CVS mortality. In conclusion, it is very important to establish all CVS risk factors in the PD patients to prevent CVS diseases and CVS mortality in this population.

Background and Aim. Several studies demonstrated a six-fold increase in plasma concentration of endothelin-1 (ET-1) in diaysis patients (hemodialysis and peritoneal dialysis) compared to healthy control subjects. However, the effects of ET-1 on respiratory function in these patients are less known. The aim of this study was to determine the potential differences in spirometric values in relation to ET-1 levels. Methods. The study included 28 patients (15 male, 13 female, mean age 55.9±16. 2 years) with end stage renal diseases (ESRD) receiving regular hemodialysis (HD), 23 patients (10 males, 13 females, mean age 55.8±15.8 years) with ESRD treated with continuous ambulatory peritoneal dialysis (CAPD) without any cardiovascular or respiratory diseases, and 30 healthy volunteers (14 male, 16 female, mean age 51.8±15.6 years) in control group. In each of the three groups the participants were divided into two additional sub-groups according to the serum levels of ET-1. The spirometry values were recorded before the onset of hemodialysis and prior to emptying the peritoneal cavity in CAPD patients. The results were analyzed using standard statistical methods (Student’s t-test). Results. Patients who were treated with HD or CAPD were found to have significant difference in values of most pulmonary function parameters between subjects with ET-1 levels lower than 6,6 pg/ml and subjects with ET-1 levels higher than 6,6 pg/ml. In the control group there was no difference in pulmonary function parameters in correlation with ET-1 levels. ET-1 values in patients of both dialysis groups were significantly higher compared to healthy subjects. Conclusions. Higher levels of ET-1 in dialysis patients over healthy subjects is associated with lower parameters of lung function tests. A possible pathophysiological mechanism for deterioration of pulmonary function might be explained by progression of inflammation, pulmonary oedema also known as “uraemic lung” or/and the progression of pulmonary hypertension.

Residual Diuresis

Abstract Introduction. Cardiovascular diseases are the leading cause of death in hemodialysis patients. The decline of residual renal function increases the prevalence and severity of risk factors of cardiovascular morbidity and mortality in these patients. Hypertension is common in dialysis patients and represents an important independent factor of survival in these patients. Methods. The study included 77 patients who are on chronic HD for longer than 3 months. Depending on the measured residual diuresis patients were divided into two groups. The study group consisted of patients with residual diuresis >250 ml/day, while patients from control group had residual diuresis <250 ml/day. All patients had their blood pressure measured before 10 consecutive hemodialysis treatments. Collected data were statistically analyzed using SPSS 16.0. Results. The study included 77 hemodialysis patients, mean age of 56.56±14.6 years and mean duration of hemodialysis treatment of 24.0 months. Of the total number of patients, 39(50.6%) had preserved residual renal function. Hypertension was more common in the group of patients who did not have preserved residual renal function (68.4% vs 25.6%). There was statistically significant negative linear correlation between the volume of residual urine output and the residual clearance of urea and values of systolic blood pressure [(rho=−0.388; p<0.0001); (rho=−0.392; p<0.0005)], values of mean arterial pressure [(rho =−0.272; p<0.05); (rho=−0.261; p=0.023; p<0.05)] and values of pulse pressure in hemodialysis patients [(rho =−0.387; p<0.001); (rho=−0.400; p<0.0005)]. Conclusions. Residual renal function plays an important role in controlling blood pressure in patients on hemodialysis. More attention should be directed to preserve residual renal function, and after the start of hemodialysis by avoiding intensive ultrafiltration with optimal antihypertensive therapy.

The Mean

The number of dialysis patients is increasing every year and is estimated to be more than 2 million, with an annual increase of 6–12% in dialysis programs. There is a high correlation between cognitive impairment and mortality in dialysis patients, which suggests the relevance of screening cognitive functions in dialysis patients using different neuropsychological scales.Aim of the study was to test the cognitive status and identify cognitive impairment in patients with terminal stage of chronic kidney disease treated using program hemodialysis, as well as to evaluate risk factors for cognitive impairment in this category of patients.Material and methods. 83 patients aged 28 to 78 years (mean age 56.7±13.7 years) were examined. The main group included 53 people who received program hemodialysis, of them 23 men and 30 women. The mean age of patients in this group was 58.3±13.3 years. The control group composed of 30 individuals without kidney diseases, including 13 men and 17 women. The mean age in the control group was 53.6±14.9 years. The MoCA and SLUMS scales were chosen for detecting cognitive impairment and assessment of neuropsychological status. We used mathematical methods of research data processing such as inductive statistics and correlation analysis.Results. Cognitive impairment was found to be significantly more frequent in dialysis patients (75.5–81.1% of cases, P=0.05) compared to those without kidney pathology. The SLUMS scale was shown to be more sensitive than MoCA (P=0.05, CI 95.0%). The risk factors of cognitive impairment in dialysis patients included increased dialysis duration, age (rs=–0.298) and low estimated urea dialysis adequacy index (Kt/V less than 1.2).Conclusion. A high risk of cognitive impairment is common in dialysis patients. For its timely detection,  the screening neuropsychological test are recommended to be used by clinicians. Cognitive impairment, diagnosed by the tests, is an indication for a specialist consultation.

Apnea Syndrome

Background : Sleep Apnea Syndrome (SAS) is a cause of hypertension, increasingcardiovascular risk and cardiovascular disease such as stroke, coronary artery disease, myocardial infarction, arrhythmias, heart failure, increasing the risk of death in patients with heart disease, independent of other causative factors. So far, in Vietnam there are very few studies on Obstructive Sleep Apnea Syndrome (OSAS) and cardiovascular risk factors . Self-making SASD07 is trustly for detecting OSAS with statistical significiant in comparision with StarDustII (gold criteria). Subjects and Methods: Cross sectional study, comparision with control group: 136 peoples (68 in disease group and 68 in control group). Patients were parallelly measured with StarDustII and SASD07 to detect OSAS and find the corellation with cardiovascular risk factors. Results: There is a positive correlation between SBP with the severity of OSAS (r = 0.459, p < 0.001), positive correlation between DBP with the severity of OSAS (r = 0.352, p < 0.003). No statistically significant differences between severe OSAS and fasting blood glucose, cholesterol, HDL Cholesterol, Non - HDL Cholesterol, LDL Cholesterol and TG median (p > 0.05). There is a positive correlation between AHI and neck circumference (r = 0.511, p < 0.001), waist circumference (r = 0.585, p < 0.001), BMI (r = 0.380, p < 0.01). SASD07 diagnostic value of detecting OSAS compared with StarDustII have Kappa = 0.72, (standard error 0.06, p <0.001). Conclusion: The risk factors related to OSAS in our study is neck circumference, waist circumference, systolic blood pressure, diastolic blood pressure. SASD07 have a good value in diagnosing of OSAS compared with polysomnography StarDustII. Key words: Sleep Apnea Syndrome, cardiovascular risk factor, SASD07.

Aim: The aim of this study was to investigate the effect of dietary education on cardiovascular risk factors in patients with rheumatoid arthritis. Method: In this randomized clinical trial, 112 patients with rheumatoid arthritis were randomly assigned into two groups, intervention and control. Dietary education was provided for the intervention group in 4 sessions; anthropometric measurements, serum levels of RF, triglycerides, cholesterol, HDL, LDL, and fasting blood sugar were measured before and three months after intervention. Data was analyzed using SPSS software and appropriate statistical tests. Results: The mean of total cholesterol (p <0.001), triglycerides (p = 0.004), LDL (p <0.001), systolic blood pressure (p = 0.001), diastolic blood pressure (p = 0.003), FBS and BMI (p <0.001) were decreased significantly in the intervention group after education compared the control group. Conclusion: Traditional care for rheumatoid arthritis patients is not enough. Patients need more education in order to improve their situation.
