ESRD Hypertension

By August 17, 2021, 4.3 million people had died globally as a result of SARS-CoV-2 infection. While data collection is ongoing, it is abundantly obvious that this is one of the most significant public health crises in modern history. Consequently, global efforts are being made to attain a greater understanding of this disease and to identify risk factors associated with more severe outcomes. The goal of this study is to identify clinical characteristics and risk factors associated with COVID-19 mortality in Mexico...

Chronic kidney disease (CKD) patients have an increased risk for cognitive impairment compared to the general population. The risk is much higher in CKD patients who progress to end-stage kidney disease (ESKD) and require hemodialysis or peritoneal dialysis. Multiple factors may contribute to cognitive impairment in CKD patients and in patients on chronic dialysis. However, the observation that, after kidney transplantation, there is an improvement in several cognitive performance markers and that some structural and functional brain abnormalities may improve suggests that cognitive deficits in patients on dialysis may be at least partially reversible...

Obesity and chronic kidney disease (CKD) are common and frequently coexisting medical conditions. Already well known to be a risk factor for type 2 diabetes mellitus (T2DM), ischaemic heart disease, stroke, hypertension, malignancy and premature death, obesity also predisposes to CKD. Elevated weight leads to declining renal function through several mechanisms, including established pathways via metabolic syndrome, hypertension and T2DM, but also through relatively recently understood glomerulosclerosis, directly related to obesity...

Extracellular vesicles (EVs) are released from all cell types studied to date and act as intercellular communicators containing proteins, nucleic acids and lipid cargos. They have been shown to be involved in maintaining homoeostasis as well as playing a role in the development of pathology including hypertension and cardiovascular disease. It is estimated that there is 109 -1010 circulating EVs/mL in the plasma of healthy individuals derived from various sources. While the effect of EVs on vascular haemodynamic parameters will be dependent on the details of the model studied, we systematically searched and summarized current literature to find patterns in how exogenously injected EVs affected vascular haemodynamics...

BACKGROUND: Polycystic kidney disease (PKD) is the most common genetic cause of kidney disease. It is a progressive and irreversible condition that can lead to end-stage renal disease and many other visceral complications. Current comprehensive data on PKD patterns in Africa is lacking. AIM: To describe the prevalence and outcomes of PKD in the African population. METHODS: A literature search of PubMed, African journal online, and Google Scholar databases between 2000 and 2023 was performed...

BACKGROUND: Multimorbidity research has focused on the prevalence and consequences of multimorbidity in older populations. Less is known about the accumulation of chronic conditions earlier in the life course. METHODS: We identified patterns of longitudinal multimorbidity accumulation using 30 years of data from in-person exams, annual follow-ups, and adjudicated end-points among 4,945 participants of the Coronary Artery Risk Development in Young Adults (CARDIA) study...

Patients with end-stage renal disease (ESRD) who undergo kidney transplantation are at an increased risk of developing surgical and/or medical complications. Posterior reversible encephalopathy syndrome (PRES) is a rare complication that occurs in 0.34% of kidney transplant patients. It is characterized by a combination of neurological manifestations, risk factors, and characteristic radiological findings in neuroimaging studies. The development of PRES has been associated with various medical conditions and factors, including hypertension, the use of cytotoxic and immunosuppressive drugs, acute or chronic kidney disease, pre-eclampsia/eclampsia, autoimmune diseases, and solid organ and bone marrow transplantation...

Chronic kidney disease (CKD) is characterized by an elevated risk for cerebrovascular disease including stroke. One mechanism that may contribute to this heightened risk is an impairment in cerebrovascular carbon dioxide reactivity (CVR). We compared CVR between CKD patients stages III-IV and controls (CON) without CKD but matched for hypertension and diabetes status. CVR was measured via 5% CO2 inhalation followed by voluntary hyperventilation in 14 CKD and 11 CON participants while mean arterial pressure, end-tidal carbon dioxide, and middle cerebral artery blood velocity (MCAv) were measured continuously...

Introduction Pulmonary hypertension (PH) is a recognized complication in patients with end-stage renal disease (ESRD undergoing maintenance hemodialysis (MHD). PH is commonly found in patients with chronic kidney disease (CKD) and ESRD. PH is associated with increased morbidity and mortality in patients with CKD. Methodology This cross-sectional study aimed to assess the prevalence of PH and its associated risk factors in MHD patients. A total of 220 ESRD patients on MHD patients at The Kidney Center, Karachi, Pakistan, aged 18-70 were included...

The antibodies directed against human leukocyte antigen (HLA) molecules, which play a crucial role in allograft histocompatibility, are called anti-HLA antibodies. Anti-HLA antibodies against foreign HLA molecules may be present in patients with chronic kidney disease even before transplantation. The panel reactive antibody (PRA) test is used to measure the renal transplant candidate's immune sensitivity to HLA molecules other than their own HLA molecules by assessing the diversity of anti-HLA antibodies in the blood of these patients...

CONTEXT: Patients with adrenal hormone excess demonstrate increased cardiovascular risk and mortality. OBJECTIVE: We aimed to determine the impact of adrenal disorders on the inflammation marker GlycA, total branched-chain amino acids (BCAA), ketone bodies and the gut microbiome-derived metabolites trimethylamine N-oxide (TMAO) and betaine. METHODS: We conducted a single-center cross-sectional study of patients with nonfunctioning adenomas (NFA), mild autonomous cortisol secretion (MACS), primary aldosteronism (PA), Cushing syndrome (CS), pheochromocytoma/paragangliomas (PPGL), other benign or malignant adrenal masses, and adrenocortical carcinoma (ACC) between January 2015 and July 2022 (n=802)...

Hypertensive nephropathy (HTN) is the second leading cause of end-stage renal disease (ESRD) and a chronic inflammatory disease. Persistent hypertension leads to lesions of intrarenal arterioles and arterioles, luminal stenosis, secondary ischemic renal parenchymal damage, and glomerulosclerosis, tubular atrophy, and interstitial fibrosis. Studying the pathogenesis of hypertensive nephropathy is a prerequisite for diagnosis and treatment. The main cause of HTN is poor long-term blood pressure control, but kidney damage is often accompanied by the occurrence of immune inflammation...

Thrombotic microangiopathy (TMA) has been observed in some patients receiving interferon beta (IFNβ) therapy for relapsing-remitting multiple sclerosis, but little is known about its clinical features and outcomes. We searched the literature to identify cases with IFNβ-related TMA and assessed their pattern of organ involvement, the presence of prodromal manifestations, the treatments used, and the outcomes. Thirty-five articles met the inclusion criteria, and data of 67 patients were collected...

BACKGROUND: Chronic kidney disease affects 10% of the world population and it is associated with progression to end stage kidney disease and increased morbidity and mortality. The advent of multi-omics technologies has expanded our knowledge on the complexity of kidney diseases, revealing their frequent genetic etiology, particularly in young subjects. Genetic heterogeneity and drug screening require patient-derived disease models to establish a correct diagnosis and evaluate new potential treatments and outcome...

BACKGROUND/OBJECTIVE: Pheochromocytoma and paraganglioma (PPGL) are rare neuroendocrine tumors. Here, we report an unusual case of synchronous PPGL in an asymptomatic patient with tuberous sclerosis complex (TSC). CASE REPORT: A 49-year-old woman with a history of TSC and end-stage renal disease was referred for evaluation of bilateral adrenal and retroperitoneal masses. She denied chest pain, palpitations, headaches, or previous hypertensive crisis. The laboratory test results showed a plasma normetanephrine level of 20...

Apparent treatment-resistant hypertension (aTRH), defined as blood pressure (BP) that remains uncontrolled despite unconfirmed concurrent treatment with three antihypertensives, is associated with an increased risk of developing cardiovascular and renal complications compared with controlled hypertension. We aimed to identify the characteristics of aTRH patients with an elevated risk of major adverse cardiovascular events plus (MACE+; defined as stroke, myocardial infarction, or heart failure hospitalization) and end stage renal disease (ESRD)...

OBJECTIVE: Loss of muscle mass and sarcopenia are common in CKD and ESRD, and sarcopenia can worsen insidiously in patients with advancing CKD. The temporal dynamics of sarcopenia in patients with progressive loss of kidney function, and its association with future outcomes, is unclear. METHODS: In a contemporary national cohort of incident ESRD US veterans, we selected 661 patients who had at least two 24-hour urine creatinine (24hrUC) measurements, a surrogate of muscle mass, performed during the 3-year prelude period prior to ESRD transition...

BACKGROUND: Peritoneal dialysis (PD) offers quality of life and empowerment for persons with end-stage kidney disease (ESKD). Nevertheless, the prevalence of PD is low in Belgium and Europe in general. Reimbursement, patient mix and late referral have been quoted as underlying reasons. However, to date no one-size-fits-all solution increasing uptake of PD has been successfully implemented. We aimed to understand the nephrologist's perspective, beliefs, and experiences on dialysis modality selection and to clarify underlying process-level and intrinsic motivations steering final decisions...

BACKGROUND: Phospholipase A2 receptor (PLA2R)-associated membranous nephropathy accounts for the majority of membranous nephropathy; however, few studies have determined the prognostic impact and clinical application of renal pathologic change on this disease. METHODS: A retrospective cohort study of 262 patients with PLA2R-associated membranous nephropathy was conducted. The total renal chronicity score calculated according to the degree of glomerulosclerosis, interstitial fibrosis, tubular atrophy, and arteriosclerosis was applied to evaluate renal chronicity...

This case report highlights the successful management of fatal cardiac tamponade caused by intravascular intervention for central vein occlusion in hemodialysis patients. Prompt diagnosis and treatment are essential for patient prognosis in such cases. We present a case involving a challenging surgical procedure to address multiple complications, emphasizing the importance of early detection and appropriate interventions. The patient, who had a history of long-term central venous catheter use for hemodialysis, was diagnosed with central vein stenosis in addition to superior vena cava occlusion, hemodialysis catheter rupture, hypertension, and end-stage renal disease...
