Chronic kidney disease (CKD) is a critical and rapidly growing global health problem. Neurological complications occur in almost all patients with severe CKD, potentially affecting all levels of the nervous system, from the central nervous system (CNS) through to the peripheral nervous system (PNS). Patients with CKD exhibit a high incidence of symptomatic and occult cerebrovascular diseases, associated tremendously high levels of inflammatory factors and homocysteine, as well as anemia, hypertension, and diabetes...

Familial lecithin-cholesterol acyltransferase (LCAT) deficiency is a rare autosomal recessive (AR) disease caused by mutation in the LCAT gene. LCAT enzyme esterifies cholesterol molecules in high-density lipoprotein(HDL) and low density-lipoprotein (LDL) particles. This enzyme deficiency is characterised by progressive corneal opacification, glomerulopathy, mild - moderate haemolytic anaemia and very low plasma levels of HDL. We here report a 34 year-old lady who presented with hypertension, nephrotic proteinuria, renal failure, corneal ring opacities, anemia and dyslipidemia...

The central dysregulated pathway of clear cell (cc) renal cell carcinoma (RCC), the von Hippel Lindau/hypoxia inducible factor-α axis, is a key regulator of intracellular iron levels, however the role of iron uptake in human RCC tumorigenesis and progression remains unknown. We conducted a thorough, large-scale investigation of the expression and prognostic significance of the primary iron uptake protein, transferrin receptor 1 (TfR1/CD71/TFRC), in RCC patients. TfR1 immunohistochemistry was performed in over 1500 cores from 574 renal cell tumor patient tissues (primary tumors, matched benign kidneys, metastases) and non-neoplastic tissues from 36 different body sites...

BACKGROUND: Cardiovascular disease has become a leading cause of death for patients with paraplegia. Acute myocardial infarction in patients with paraplegia has not been described in literature. Evidence gathered from studies of acute myocardial infarction in ambulating individuals may not be directly applicable to paraplegic patients. This study investigates clinical features, management strategies, and outcomes of acute myocardial infarction in patients with paraplegia. METHODS: Acute myocardial infarction in patients with or without paraplegia was identified in the New York State Inpatient Database between 2007 and 2013...

While the epidemiology of adult heart failure has been extensively researched, this systematic review addresses the less well characterized incidence and prevalence of pediatric HF. The search strategy used Cochrane methodology and identified 83 unique studies for inclusion. Studies were categorized according to whether the HF diagnosis was reported as primary (n = 10); associated with other cardiovascular diseases (CVDs) (n = 49); or associated with non-CVDs (n = 24). A narrative synthesis of the evidence is presented...

Inhibition of hypoxia inducible factor prolyl hydroxylase (PHD) represents a promising strategy for the discovery of a next generation treatment for renal anemia. We identified several 5,6-fused ring systems as novel scaffolds of the PHD inhibitor on the basis of pharmacophore analysis. In particular, triazolopyridine derivatives showed potent PHD2 inhibitory activities. Examination of the predominance of the triazolopyridines in potency by electrostatic calculations suggested favorable π-π stacking interactions with Tyr310...

Normocytic normochromic anemia is a common complication of chronic kidney disease (CKD) and is associated with numerous adverse consequences. Certain symptoms previously attributed to CKD are now known to be a consequence of anemia. Anemia contributes to an increased cardiac output, and the development of left ventricular hypertrophy, angina and congestive heart failure, leading to high morbidity and mortality in patients with CKD. The multifunctional α-klotho (KL) protein, which is predominantly expressed in the kidneys, is associated with the occurrence of anemia in patients with CKD...

Acute kidney injury (AKI) due to intravascular hemolysis has been well described in paroxysmal nocturnal hemoglobinuria (PNH) and in cardiac valvular dysfunction. However, reported cases of hemoglobinuric AKI from prosthetic aortic grafts are sparse. We present a case of microangiopathic hemolytic anemia and hemoglobinuric AKI presenting 9 days after repair of an ascending aortic dissection with a prosthetic graft. After an unremarkable recovery following the initial procedure, the patient presented on postoperative day 9 with dyspnea, fatigue, and cola-colored urine...

A 4-year-old boy presented with nonimmune hemolysis, thrombocytopenia, and acute kidney injury. Investigations for an underlying cause failed to identify a definitive cause and a putative diagnosis of complement-mediated atypical hemolytic uremic syndrome (aHUS) was made. The patient was started initially on plasma exchange and subsequently eculizumab therapy, after which his kidney function rapidly improved. While on eculizumab therapy, despite adequate complement blockade, he presented 2 more times with hemolytic anemia and thrombocytopenia, but without renal involvement...

The basal ganglia (BG) are composed of several nuclei involved in neural processing associated with integration of sensory and motor information. Recent neuroimaging studies implicated its key role in control of voluntary motor function. As the sensorimotor abnormality is common among the end-stage renal disease (ESRD) population, in the current study, we aimed to investigate the abnormal structure and functional connectivity patterns of BG in ESRD patients. Twenty-nine ESRD and twenty-nine age and gender-matched healthy controls (HC) were enrolled to compare the volume of the subsets in the BG (e...
