INTRODUCTION: Pulmonary artery hypertension (PAH) is common in end stage renal disease (ESRD) patients undergoing hemodialysis. Fibroblast growth factor-23 (FGF-23) increases in hemodialysis but its relationship with PAH is not completely understood. The aim of this study was to evaluate the relation between FGF-23 level and development of PAH in ESRD patients undergoing hemodialysis. METHODS: Patients undergoing hemodialysis for more than 6 months were enrolled in this cross-sectional study...

BACKGROUND: Pulmonary hypertension (PH) is common in patients with end-stage renal disease (ESRD). Arteriovenous fistulas (AVF) creation may involve in the pathogenesis of PH. The aim of this study was to explore the impact of PH after AVF creation on the AVF failure rate in maintenance hemodialysis (MHD) patients. METHODS: From January 1, 2009, to January 1, 2019, we retrospectively collected data of 578 MHD patients in Guangdong Provincial People's Hospital Blood Purification Center, China...

INTRODUCTION: There is an increased risk of thrombotic complications in patients with COVID-19. Hemodialysis patients are already at an increased risk for thromboembolic events such as stroke and pulmonary embolism. The aim of our study was to determine the incidence of late thrombotic complications (deep vein thrombosis, pulmonary embolism, stroke, new-onset vascular access thrombosis) in maintenance hemodialysis patients after recovery from COVID-19. METHODS: We performed a retrospective cohort study of 200 prevalent hemodialysis patients in our center at the start of the pandemic...

Treatment of atherosclerotic renal artery stenosis (RAS) is still controversial. Several randomized controlled trials have shown that percutaneous transluminal renal angioplasty with stenting (PTRAS) is not superior to medical treatment, and the procedure is commonly reserved for malignant hypertension, flash pulmonary edema or deterioration of kidney function. The most challenging symptomatic RAS cases are patients with severe stenosis resulting in acute kidney injury (AKI) requiring acute hemodialysis. The risk-benefit ratio in these cases is uncertain...

Background and objectives Pulmonary hypertension (PH) is an independent risk factor for increased mortality, especially in patients undergoing hemodialysis (HD), but the mechanism of its development is unknown. This study aimed at evaluating volume overload and inflammation as potential variables to cause its development in patients undergoing maintenance hemodialysis. Materials and methods This was an observational cross-sectional study conducted on patients undergoing hemodialysis at a tertiary hospital in northern India...

BACKGROUND: Systemic oxalosis is a severe complication seen in primary hyperoxaluria type I patients with kidney failure. Deposition of insoluble calcium oxalate crystals in multiple organs leads to significant morbidity and mortality. METHODS: We describe a retrospective cohort of 11 patients with systemic oxalosis treated at our dialysis unit from 1982 to 1998 (group 1) and 2007-2019 (group 2). Clinical and demographic data were collected from medical records...

AIMS: Systolic pulmonary artery pressure (SPAP) and right heart adaptation in relation to pre-existing preload are often disregarded. To determine volume-related changes in the pulmonary-right ventricle (RV) unit and the preload dependence of its components, we analysed pulmonary haemodynamics and right ventricular performance, taking advantage of the plasma volume removal associated to haemodialysis (HD). METHODS AND RESULTS: Fifty-three stable patients on chronic HD with LVEF > 50% and without heart failure were recruited (mean age 63...

Coronavirus disease 2019 (COVID-19) is associated with considerable morbidity and mortality. The number of confirmed cases of infection with SARS-CoV-2, the virus causing COVID-19 continues to escalate with over 70 million confirmed cases and over 1.6 million confirmed deaths. Severe-to-critical COVID-19 is associated with a dysregulated host immune response to the virus, which is thought to lead to pathogenic immune dysregulation and end-organ damage. Presently few effective treatment options are available to treat COVID-19...

BACKGROUND: IgG4-related kidney disease (IgG4-RKD) can affect multiple organs, which was first reported as a complication or extra-organ manifestation of autoimmune pancreatitis in 2004. It is characterized by abundant IgG4-positive plasma cells infiltration in tissues involved. CASE PRESENTATION: A 69-year-old man presented with cough and renal dysfunction with medical history of hypertension and diabetes. Pathological findings revealed interstitial nephritis and he was initially diagnosed with IgG4-RKD...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus identified after widespread pneumonia cases in Wuhan, China at the end of 2019. This virus has been deemed a global pandemic and there remain many unknowns regarding the pathogenesis, management, treatment, and outcomes. This case report highlights a rare condition that possibly developed from the novel virus.  A 68-year-old Hispanic male with hypertension and gastroesophageal reflux disease, presented with two weeks history of fevers, chills, cough, and progressive shortness of breath...

INTRODUCTION: Pulmonary hypertension (PH) is a recently recognized as a complication of chronic kidney disease and end-stage renal disease. The pathogenesis of pulmonary hypertension in this group of patients is not fully understood, probably due to the interaction of multiple aspects of the altered cardiovascular physiology and also hormonal and metabolic disorders. The present study aimed to determine the prevalence of PH, correlation with cardiac function and other risk factors and its impact of survival in chronic hemodialysis and peritoneal dialysis patients...

Introduction: Pulmonary hypertension (PH) is a common yet incompletely understood complication of chronic kidney disease (CKD). Although transthoracic echocardiogram is commonly used to noninvasively estimate PH, it has not been validated in a CKD population. We investigated the utility of this diagnostic tool for CKD-associated PH in a large right heart catheterization (RHC) cohort. Methods: We reviewed RHC and echocardiography data in 4036 patients (1714 with CKD) obtained between 2011 and 2014 at a single center...

BACKGROUND: Increased right ventricular systolic pressure (RVSP), a surrogate marker for pulmonary hypertension, is common in patients with end-stage kidney disease. Limited data suggest improvement of RVSP with intensive dialysis, but it is unknown whether these improvements translate to better clinical outcomes. METHODS: We conducted a retrospective single center cohort study at the Toronto General Hospital. All patients who performed intensive home hemodialysis (IHHD) for at least a year between 1999 and 2017, and who had a baseline as well as a follow-up echocardiogram more than a year after IHHD, were included...

The purpose of this study is to determine the mortality among patients on hemodialysis (HD). This observational cohort study was conducted at Dubai Hospital during the period between January 2012 and December 2016. All adults' patients with end-stage renal disease (ESRD) on HD irrespective of their age, gender, and duration of dialysis were enrolled. Mortality among these patients along with certain information like age at the time of death, gender, cause of ESRD, comorbidities, and serology report, were collected...

BACKGROUND: Although cardiovascular diseases in particular Pulmonary Arterial Hypertension (PAH) is associated with, high morbid-mortality in chronic hemodialysis, but its magnitude remains paradoxically unknown in sub-Saharan Africa. The aim of this study was to evaluate the prevalence of PAH and associated factors in chronic hemodialysis in Sub-Saharan African population. METHOD: In a cross-sectional study, patients treated with HD for at least 6 months in 4 hemodialysis centers were examined...

Chronic kidney disease is associated with increased cardiovascular morbidity and mortality. A well-functioning vascular access is associated with improved survival and among the available types of vascular access the arterio-venous (AV) fistula is the one associated with the best outcomes. However, AV access may affect heart function and, in some patients, could worsen the clinical status. This review article focuses on the specific cardiovascular hemodynamics of dialysis patients and how it is affected by the AV access; the effects of an excessive increase in AV access flow, leading to high-output heart failure; congestive heart failure in CKD patients and the contraindications to AV access; pulmonary hypertension...

Context: Cases of heart failure with preserved ejection fraction (HFpEF) exacerbations continue to affect patients' quality of life and cause significant financial burden on our healthcare system. Objective: To identify risk factors for readmission in patients discharged with a diagnosis of HFpEF. Methods: Electronic health records of patients over 18 years of age with a primary diagnosis of HFpEF treated between August 1, 2017 and March 1, 2018 in a community hospital were retrospectively reviewed...

Introduction: Central venous catheter (CVC) insertion is the most commonly performed clinical procedure when a patient initiates hemodialysis. Despite its clinical benefits, CVC insertion has several risks of complications. Thrombosis, venous stenosis, infection, arrhythmia, pneumothorax, and bleeding are among these complications. Malposition of the tip of the CVC can also occur with an incidence of up to 7%. One of several factors that could contribute to malposition is venous anatomy variation...
