Association of serum fibroblast growth factor-23 with Doppler pulse wave velocity in hemodialysis patients.

Association of serum fibroblast growth factor-23 with Doppler pulse wave velocity in hemodialysis patients. Saudi J Kidney Dis Transpl. 2018 Jan-Feb;29(1):95-100 Authors: Ibrahim WH, Ahmad AB, Sayed NG Abstract We aimed to study the association of fibroblast growth factor-23 (FGF-23) as a novel cardiovascular risk factor with Doppler pulse wave velocity (PWV) as an arterial stiffness measuring tool in hemodialysis (HD) patients. We conducted a cross-sectional study in which blood samples from 86 HD patients were obtained to estimate FGF 23 and other parameters. Flow waveforms were obtained at two locations within right common carotid artery, and right femoral artery by Doppler ultrasound with ECG recorded in addition. The time differences between the R wave of the ECG signal and the onset of the flow waveforms at the two sites yield ΔT. Distances between sampling sites were measured using a tape measure. PWV was defined as (m/s) = D (m)/ ΔT (s). In the current study, we found significant positive correlations between Doppler PWV and both age (r = 0.401, P = 0.039) and systolic blood pressure (r = 0.602, P = 0.034), while no significant association between Doppler PWV and FGF-23 (r = 0.123, P = 0.259) could be detected. Serum FGF-23 levels are not significantly associated with Doppler PWV in HD patients. PMID: 29456213 [PubMed - in process]

Discussion: Incomplete septal cirrhosis is an uncommon cause of non-cirrhotic portal hypertension. Its definition is not well known, morphological and pathophysiological. We have not found published cases of post-RT ascites secondary to this pathology, described as possibly associated with drugs, immune alterations, infections, hypercoagulability and genetic predisposition.

Authors: Laranjinha I, Matias P, Oliveira R, Casqueiro A, Bento MT, Carvalho AP, Adragão T, Jorge C, Bruges M, Birne R, Machado D, Weigert A Abstract INTRODUCTION:: After a kidney transplant, it is unknown whether the maintenance of a functioning hemodialysis arteriovenous access could have deleterious effects on renal grafts. We hypothesize that maintaining an arteriovenous access can deviate a significant proportion of the cardiac output from the renal graft. The aim of this study was to investigate whether a temporary closure of the arteriovenous access could lead to an increase in graft perfusion. ME...

Conclusions: Renal disease proved to be associated with early and subclinical impairment of LV systolic function, which persists after starting dialysis and even in spite of successful kidney transplantation. An increased E/e ’ resulted to be the most powerful independent predictor of abnormal GLS.Cardiorenal Med 2019;9:61 –68

Abstract End-stage renal disease (ESRD) patients have been associated with accelerated vascular disease of the cerebral circulation due to uremic toxins. Furthermore, anemia increases cerebral oxygen extraction fraction which impairs the cerebral vasodilatory capacity. We evaluated the effect of correction of anemia on cerebral blood flow by measuring the mean blood flow velocity, resistance index (RI), and pulsatility index (PI) in the middle cerebral artery (MCA) in relation to cognitive functions. We measured the mean blood flow velocity, RI, and PI in MCA of 120 ESRD patients when the hemoglobin (Hb) ranges be...

CONCLUSION: Diagnostic and Interventional Nephrology is slowly spreading in Spain. It includes basic techniques to our specialty, allowing nephrologists to be more independent, efficient, and reducing waiting times and costs, overall improving patient care. Nowadays, more nephrologists aim to perform them. Therefore, appropriate training on different techniques should be warranted, implementing an official certification and teaching programs.

Abstract Endothelial progenitor cells (EPCs) CD34 are bone marrow-derived cells that decrease in chronic kidney disease (CKD) patients especially when they reach end-stage renal disease and may be a risk marker of cardiovascular (CV) diseases. The aim of our study is to investigate the endothelial progenitor cell CD 34 numbers in children with CKD on regular hemodialysis (HD) and detect their association with vascular stiffness. We recruited 25 children on regular HD, who were selected from the HD unit of Al-Zahraa Hospital, Al-Azhar University. Another group of 25 age and sex matched healthy children served as as...

Abstract A 27-year-old man with terminal renal failure requiring peritoneal dialysis for the past 2 years was referred to the dermatologist for evaluation of red violaceous macular skin lesions consistent with livedo reticularis. These lesions had appeared suddenly on his legs (Figure 1). He had first experienced recurrent nephrolithiasis at the age of 14. Results from urine analysis and abdominal ultrasound revealed chronic kidney failure. Because the patient had a sister with similar findings, primary hyperoxaluria (PH) was suspected and genetic testing was performed in all members of his family. The results con...

CONCLUSION: End-to-side anastomosis can be done in some chronic kidney failure patients if their internal iliac arteries are large enough. This approach is safer than anastomosis using the external iliac artery. PMID: 28744151 [PubMed]
