Each haemodialysis treatment requires the application of anticoagulation medicines, which will prevent coagulation in extracorporal blood circulation. In this study we try to determine the quality of admitted anticoagulant and his effect on lipid profile on hemodialysis patients after twelve months. We were applying standard heparin and low weight molecular heparin (LWMH). During our study we was analyzed effect of anticoagulant therapy on lipid profile of hemodialysis patients. In that parameters was included triglycerides, cholesterol, lipoprotein fractions, complete blood count, Hgb, HCT; All of these parameters was analyzed in correlation with duration of hemodialysis treatment, sex and age of the patients. Our research was carried out as a prospective study, for the period of 12 months. In the study were included 60 patients (34M/26F), who were on chronic hemodialysis program. All patients were divided into two groups. The first group of patients was included 27 patients (15M/12F) who were treated with standard heparin. The second group was included 33 patients (19M/14F) treated with LWMH (enoxaparin). The average length of hemodialysis was 4.15 +/- 0.52 years. Each patient had a protocol in which is marked parameters such as flushing dialysator, creating fibrin-ring in vein and arterial dropper and the time it takes to stop the bleeding. In the results the average age amounted to 58.54 +/- 2.24 years. The average value of cholesterol in the blood was 5.38 +/- 2.26. Values of HDL-cholesterol in patients treated with LWMH were significantly lower (P<or=0.05) in the treated group compared to standard heparin. There were no significant statistical differences between both groups in relation to the level of LDL cholesterol in the blood. (p ns). LWMH had a better effect on the irrigation system and dialysator on both sex equally, compared with standard heparin. LWMH is in the female dialysis population has led to improvements in lipid profile. After the first six months of study in male patients treated with standard heparin in relation to the female part of the observed patients was significantly better anticoagulation effect in the first half of the study (1.85 +/- 0.05 compared to 2.09 +/- 0.10) (P<or=0.001). Average rating blood clots were statistically significant for standard heparin (p<or=0,001) with 1,86 at the beginning the value is fell to 1.41, while for LWMH with 1.85 at the beginning of the study amounted to 1.52 grade average. (P<or=0.05). The results of our study show that LWMH had a better rinsing effect of dialysis systems and dialysator in both sex equally, compared to standard unfractioned heparin. When the male part of the respondents in the first six months of standard heparin had a better evaluation of blood clots than women in the same group, and also better than the group on enoxaparin for both gender. LWMH in female dialysis population has led to improved lipid profiles. Patients treated with standard heparin had a statistically significant reduction in the rate of blood clots than patients who received enoxaparin (LWMH). Such differences were minimal, which can be interpreted by the fact that LWMH still derivative of the standard heparin.
INTRODUCTION Cardiovascular diseases are the most frequent causes of morbidity and mortality in patients with chronic renal disease. The aim of our paper is to evaluate the risk factors of cardiovascular complications in patients with various stages of chronic renal disease (CRD), with or without diabetes mellitus (DM). PATIENTS AND METHODS The study included 98 patients with different stages of the CRD, with creatinine clearance <60 ml/min/1.73m2, and laboratory parameters monitored: homocysteine, BNP, cholesterol, LDL, HDL, HbA1c, Body Mass Index (BMI). First group comprised 49 patients with DM, age 50-82 years, M 28/F 21. Second group comprised 49 patients without DM, age 35-80 years, M 18/F 31. The IMT (intima media thickness) was measured by B-mode ultrasonography, and all patients had echocardiography examination done by 2D Doppler ultrasonography. RESULTS The IMT values in diabetic patients had statistically significant positive correlation with homocysteine values of r=0.9393, p<0.034, and cholesterol r=0.289, p<0.05, compared to non-diabetics. A significant negative correlation was found between the ejection fraction (EF) and BMI in both groups, more prominent in non-diabetics r=0.289, p<0.044 (diabetics r=0.162, p>0.05). 47.4% of diabetics had arteriosclerotic changes on carotid arteries, 8.5% had stenosis of ACC, and 22.0% had rhythm abnormalities on ECG. A positive correlation between IMT and BMI was found in diabetics, but was not statistically significant r=0.111, p>0.05. In the diabetics group a significantly higher (p<0.05) values of BNP, HbA1c, proteinuria, BMI, and cholesterol were found, and significantly lowered EF (p<0.0001). CONCLUSION Risk factors for cardiovascular complications in patients with DM are various, and the most pronounced significance was found in the values of homocysteine, BNP and cholesterol.
Patients with End-Stage Renal Disease (ESRD) are at high risk of death as a result of the cardiovascular disease (CVD), which cannot be explained by the conventional risk factors only. Haemodialysis patients frequently have elevated serum concentrations of the cardiac troponins T, specific markers of myocardial injury. Plasma levels of brain natriuretic peptide (BNP) are elevated in fluid volume overload and heart failure, and decreased during dialysis. Currently, LV hypertrophy and LV dysfunction are considered the strongest predictors of cardiovascular mortality in dialysis population, and the synthesis of cardiac natriuretic peptides is high in the presence of alterations in the left ventricular (LV) mass and function. The aim of this study was to investigate the factors associated with the increased serum levels of BNP and CTN in haemodialysis patients, and their impact on cardiovascular morbidity. In this cross-sectional study we included 30 patients with ESRD, without coronary symptoms, who were subjected to regular dialysis treatment three times a week for the duration of four hours. Heart failure was defined as an ejection fraction (EF) of < 35%, and dyspnoea associated with either elevated jugular pressure or interstitial oedema evidenced in chest X-ray. All patients were in sinus rhythm at the time of the study. Twenty-five patients were on erythropoietin treatment. Blood samples were taken before and after the dialysis session. Our study included 30 patients (17 males, 13 females). The average age was 53,8 years (total range 31-74) divided into two groups: euvolemic and hypervolemic. The average dialysis time was 70,3+/-46,95 months. All haemodialysis patients had excessively high levels of BNP 2196,66+/-4553,86 ng/cm3. Plasma cTnT was found to be increased in 33,3% of patients. Patients with hypervolemia had significantly higher cTnT levels (0,0577+/-0,0436), as compared to the euvolemic patients 0,0184+/-0,0259 p<0,05. The elevated cTnT significantly correlated with the level of BNP (p<0,01), while average post-dialysis BNP was not significantly lower (1698,06+/-3499,15; R=0,191; p-ns.) as compared to the pre-dialysis BNP (1839,13+/-3691,55; R=432; p<0,01). The pre-dialysis cTnT was lower (0,0315+/-0,0372) as compared to the post-dialysis cTnT (average 0,0399). Euvolemic patients had BMI 24,28+/-3,15, as compared to the hypervolemic patients BMI 25,71+/-4,20 (p-n.s.). Increased BNP was not in correlation with older age (R-0,271 p-ns.) and duration of dialysis (R-0,198). The hematocrit level increases significantly during haemodialysis (39,9%; p<0,05). Patients with higher BNP and cTnT have significantly higher indexed left ventricular mass, as compared to the patients with normal ventricular function. Our study shows that 33,3% of asymptomatic patients on haemodialysis have elevated cTnT while all patients have elevated BNP. Measuring the plasma concentration of brain natriuretic hormones may be useful for identification of the dialysis patients with LVH.
