Serum asymmetric-dimethylarginine, apelin and NT-pro BNP levels in dialysis patients
No full textBackground: The relationships among serum Apelin, Asymmetric- dimethylarginine (ADMA), N-terminal probrain natriureticpeptide (NT-proBNP) levels, and blood pressures in dialysis patients are not well known. Materials and Methods: Age and sex matched 30 hemodialysis (HD), 30 peritoneal dialysis (PD) patients, and 20 healthy controls were recruited. Serum apelin-36, ADMA, NT-proBNP levels, and blood pressures of both patients and healthy controls were measured and compared. Results: Serum ADMA and Apelin levels in HD patients were significantly higher than in PD patients. In multiple regression analyses the predictors of higher serum apelin levels were higher BMI, higher ADMA and lower systolic blood pressure. The predictors of serum ADMA levels were being on HD. The predictors of serum NT-proBNP levels were lower serum albumin and higher systolic blood pressure. Conclusion: Being on HD is a predictor of high ADMA levels. HD might be less effective on ADMA removal than PD. It seems that higher serum apelin levels related with lower sytolic blood pressure levels, whereas higher NT-proBNP levels related with higher sytolic blood pressure levels indicating potential roles as independent prognostic factors for systolic hypertension in dialysis patients.Inonu University Medical Research CenterThis study was supported by Inonu University Medical Research Center
Serum Fetuin-A Levels, QT Dispersion and P Dispersion in Dialysis Patients
No full textBackground: This study aims to find association of fetuin-A with serum lipids, QT dispersion (QT-d), and P dispersion (P-d) in dialysis patients. Methods: Fetuin-A serum levels were assessed in 50 dialysis patients. Results: Serum fetuin-A levels were significantly associated with QT-d (r = 0.289, p = 0.044), P-d (r = 0.39, p = 0.005), total cholesterol (r = 0.526, p = 0.000), low-density lipoprotein cholesterol (LDL-C) (r = 0.456, p = 0.00), triglyceride (r = 0.360, p = 0.011) and highly sensitive C-reactive protein (hsCRP) (r = -0.347, p = 0.030). In step-wise multiple regression analysis including being on hemodialysis (HD), presence of diabetes mellitus (DM), total cholesterol, LDL-C, triglycerides, hsCRP, only total cholesterol (b = 0.419, p = 0.03), and hsCRP (b = -0.316, p = 0.03) proved to be independent predictors of serum fetuin-A levels. QT-d showed a linear correlation with total cholesterol (r = 0.309, p = 0.029), LDL-C (r = 0.304, p = 0.038), P-d (r = 0.390, p = 0.005), and fetuin-A levels (r = 0.289, p = 0.044). In multiple regression analyses, the independent predictor of QT-d was being on HD (b = -0.417, p = 0.004), whereas total cholesterol, LDL-C, presence of DM, serum fetuin-A levels, and P-d had no independent effect on corrected QT (QT-C). Being on HD and age were important determinants of P-d whereas presence of DM, total cholesterol, LDL-C, fetuin-A, and QT-d had no independent effect on P-d. Conclusions: Lower fetuin-A levels are associated with high hsCRP and low cholesterol levels in dialysis patients

A Novel Technique in the Treatment of Lymphoceles After Renal Transplantation: C-Arm Cone Beam CT-Guided Percutaneous Embolization of Lymphatic Leakage After Lymphangiography
No full textBackground We aimed to evaluate the efficacy of percutaneous embolization after lymphangiography using C-arm cone-beam computed tomography (CBCT) performed at the site of lymphatic leakage in patients with postrenal transplant lymphocele. Methods Between July 2014 and August 2017, 13 patients not responding to percutaneous ethanol sclerotherapy and conservative treatment for recurrent lymphocele after renal transplant were included. The mean age of the patients was 56.38 9.91 (range, 36-70) years, and it comprised 9 men and 4 women. All patients underwent intranodal lymphangiography. C-arm CBCT-guided percutaneous embolization was performed in patients with confirmed lymphatic leakage. Patients who had no lymphatic leakage underwent drainage with fibrin glue injection. Results Lymphatic leakage was observed in 9 patients after lymphangiography, and they underwent CBCT-guided percutaneous N-butyl-2-cyanoacrylate embolization. The volume of lymphatic drainage reduced to less than 10 mL in 8 patients. One patient who was not responding to embolization was treated surgically, after percutaneous drainage and fibrin glue injection. Lymphatic leakage was not observed in 4 patients after lymphangiography. Of these, 3 patients showed a reduction in the amount of lymphatic drainage after lymphangiography. All 4 patients underwent percutaneous drainage and fibrin glue injection. One patient did not respond to the treatment and was treated surgically. Prelymphangiography and postlymphangiography and embolization, the volume of lymphatic drainage was 113.07 +/- 21.75 mL, and 53.84 +/- 30.96 mL, respectively, and statistically significant decrease was detected (P < 0.005). Conclusions Lymphangiography and CBCT-guided percutaneous embolization procedures might be an effective treatment method for patients with lymphocele refractory to treatment
Vascular calcification is not related to serum fetuin-A and osteopontin levels in hemodialysis patients
No full textIntroduction: Vascular calcification (VC) in hemodialysis (HD) patients is a sign of severe cardiovascular disease and can predict cardiovascular outcomes. Fetuin-A and osteopontin (OPN) inhibit VC. Serum fetuin-A levels are lower in patients with end-stage kidney disease (ESKD) and in those who are on chronic HD therapy. However, there are limited data concerning OPN in patients who are on dialysis. The aim of our study was to determine VC in HD patients, the relationship between VC and 25-OH-vitamin D, fetuin-A, and OPN levels, and independent predictors of VC. Materials and methods: Ninety-three patients with ESKD on HD therapy were recruited. Among these patients, 44 were male and 49 were female. The patient group was compared with a group of 20 healthy controls of similar age and sex. A plain radiograph of the hand was taken using a mammography machine for the evaluation of VC. Serum fetuin-A, OPN, and 25-OH-vitamin D levels of both patients and controls were measured. Results: VC was detected in 45 (48.4%) HD patients. When patients were compared with healthy controls, fetuin-A levels (p < 0.029) were significantly lower in patients, whereas OPN (p < 0.000) and VC (p < 0.002) were significantly higher in the patient group. Age [odds ratio (OR) 1.036], the presence of diabetes mellitus (DM) (OR 17.527), and high parathyroid hormone (PTH) levels (OR 1.002) were independent predictors of VC in a logistic regression model including the following factors: age, the presence of DM, HD duration, and serum albumin, phosphate, PTH, 25-OH-vitamin D, fetuin-A, OPN, and calcium levels. No significant correlation was found between patients with VC and patients without VC in terms of fetuin-A, OPN, and 25-OH-vitamin D levels. Conclusions: VC is a frequent sign in patients undergoing HD and is not related to serum fetuin-A and osteopontin levels. Age, the presence of DM, and high PTH levels were independent predictors of VC in patients undergoing HD. Further studies are warranted to understand the mechanism underlying and the factors contributing to VC
