Evaluation of the Risk of Nephrogenic Systemic Fibrosis (NSF) in Patients With Chronic Kidney Disease...
Renal InsufficiencyThe objective of this long term study is to prospectively evaluate the incidence of NSF in patients with severe CKD or kidney failure including patients undergoing dialysis (stages 4 and 5 i.e., with an eGFR below 30)who have not had exposure to a GBCA within 10 years prior to enrollment.

Endolymphatic Sac Tumors in a Population of Patients With Von Hippel-Lindau Disease:The Natural...
DeafnessKidney Diseases3 moreThe von Hippel Lindau (VHL) gene has recently been identified as the genetic defect resulting in a syndrome of multiple neoplasias. Patients with VHL disease develop retinal angiomata, renal cysts and/or carcinomas, CNS hemangioblastomas as well as pancreatic cysts and pheochromocytomas. Investigators have shown the gene to be a tumor suppressor type proto-oncogene located at chromosomal locus 3p26. The gene includes three exons whose gene product targets a cellular transcription factor Elongin SIII. Binding of the VHL proteins to two subunits of this elongation factor inhibits transcription and may play a crucial role in the clinical development of the von Hippel Lindau phenotype.
The Discrepancy in Radiologists' Practice of Intravenous Contrast Imaging Studies Among Chronic...
Chronic Kidney DiseasesChronic Kidney Disease 5DThere is a discrepancy between protocols used for intravenous imaging for chronic kidney disease including hemodialysis patients among different hospitals and even, among radiologists same selves. This questionnaire based study aims to quantify that discrepancy and describe the variables associated with the discrepancy.
The Impact of Selected Factors on the Cardiovascular System in Chronic Kidney Disease
Atherosclerosis of ArteryInflammation3 moreChronic kidney disease (CKD), is characterized by accelerated development of atherosclerosis and advanced remodelling of vessels and the heart. It is associated with many factors, including inflammation, arterial hypertension, hyperlipidemia, hyperhomocysteinemia, secondary hyperparathyroidism, and oxidative stress. Hypertension is one of the most critical risk factors for cardiovascular complications. It leads to the formation of structural changes in the vascular system: it impairs the activity of the endothelium, causes hypertrophy and remodelling of the vascular wall, reduces the susceptibility of the vessels and accelerates the development of atherosclerosis. This study aimed to identify the processes and their representative markers, the concentration of which in the serum may reflect the cardiovascular system status and can predict the increased mortality in HD patients.
COVID-19 Among Children With Chronic Renal Diseases in Qatar
Chronic Kidney DiseasesCOVID-19 Infection3 moreCoronavirus disease 2019 is a novel viral disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 virus. The original cases occurred in Wuhan, China, in December 2019 and rapidly spread to other areas worldwide, constituting a pandemic with unimaginable health and economic consequences. the World Health Organization elevated the disease to the category of a pandemic on March 11, 2020. In children, the reported mortality rates were far below 1%, while in people above the age of 70 years it was above 5% or higher. So, in this retrospective study, the investigators describe the clinical features and outcomes of children with chronic kidney diseases who were diagnosed with Severe Acute Respiratory Syndrome Coronavirus 2 infection at pediatric centers in Doha from 1st March 2020 till January 20th, 2022. This review looks into the literature on pediatric patients with chronic kidney diseases to verify whether they were more prone to developing more severe symptoms when diagnosed with Coronavirus disease 2019 compared to children without chronic kidney diseases and adults with chronic kidney diseases, and the Prevalence of COVID-19 infection between patients with chronic kidney diseases, and the role of COVID-19 infection in increasing the relapses and deterioration of chronic kidney diseases.
Hypomagnesemia and Diabetic Nephropathy

Metabolic Syndrome and Contrast Induced Nephropathy
Contrast Induced NephropathyMetabolic SyndromePrevention of contrast induced nephropathy after interventional cardiologic procedures deserves close interest because of its association with prolonged hospitalization, increased cost and increased in hospital and long term mortality rates. An observational prospective cohort study was designed to determine whether metabolic syndrome predicts the development of contrast induced nephropathy after elective percutaneous coronary intervention.
Endothelial Microparticles: A Novel Marker of Vascular Dysfunction
Chronic Kidney DiseaseThe primary hypothesis of this proposal is that chronic kidney disease (CKD) and treatment with calcineurin inhibitors (CNIs) are each associated with the release of endothelial microparticles into the plasma.
