BACKGROUND: Diabetes mellitus and hypertension are the leading causes of cardiovascular disease in the renal transplant recipients. This review looks at the potential role of sodium-glucose cotransporter 2 inhibitors (SGLT2is) and reviews the management strategies for hypertension in this population. SUMMARY: Large-scale clinical trials are needed to study the potential cardiorenal benefits and risks of complications in renal transplant recipients. Future clinical trials are also needed to define optimal blood pressure treatment goals and therapies and how they influence graft and patient survival...

INTRODUCTION: The clinical significance of persistent hematuria degrees has not been expounded in primary IgA nephropathy (IgAN) and requires further research. METHODS: From January 2003 to May 2022, a total of 684 IgAN patients with persistent hematuria were enrolled to conduct a retrospective single-center study. Patients whose hematuria degree at baseline was higher than the second tertiles of the whole were included in the high-degree hematuria cohort (Hh), and the low-degree hematuria cohort (Lh) was constructed with 1:1 matched cases from the rest according to age, gender, and estimated glomerular filtration rate (eGFR) at baseline and follow-up time...

INTRODUCTION: Hyporesponsiveness to erythropoiesis-stimulating agents (ESAs) affects 10-15% of the chronic dialysis population. We explored baseline characteristics and predictors of ESA hyporesponsiveness in a global randomized cardiovascular outcomes study comparing an investigational hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI), daprodustat, with conventional ESA treatment. METHODS: ASCEND-D (NCT02879305) recruited 2,964 chronic dialysis patients receiving ESA treatment (standardized to weekly intravenous [IV] epoetin) who were iron replete at baseline...

BACKGROUND: Diabetic kidney disease (DKD) is a common disorder with multiple serious clinical implications, including an increased risk of end-stage kidney disease (ESKD), cardiovascular complications, heart failure, onset or worsening of hypertension, and premature death. Patients with DKD frequently require dialysis or kidney transplantation to manage their ESKD. SUMMARY: Upregulation of the renin-angiotensin-aldosterone system is an important contributor to kidney disease progression, as highlighted by the results of trials evaluating angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in patients with albuminuria...

INTRODUCTION: Cardiac arrhythmias are the most common cause of death in hemodialysis. Autonomic dysfunction plays a central role in this arrhythmogenic background. Previous studies on hemodialysis-related changes in heart-rate-variability(HRV) give contradictory results. This study investigated HRV indices both at rest and in response to physical and mental stimulation maneuvers at multiple time-points around and during the hemodialysis procedure. METHODS: Autonomic function was assessed by linear and non-linear HRV indices at pre-dialysis, during-dialysis(3 equal time-periods), post-dialysis, and on the non-dialysis day in 36 hemodialysis patients...

INTRODUCTION: Elevated levels of fibroblast growth factor-23 (FGF23) in chronic kidney disease (CKD) are associated with progression of CKD. FGF23 inhibits proximal tubular phosphate reabsorption, raising phosphate concentrations in the tubular fluid of functioning nephrons, predisposing to spontaneous precipitation of calcium phosphate crystals and resultant tubular injury. Calciprotein monomers (CPM) form spontaneously in biological fluids when clusters of calcium phosphate ions are bound by the liver-derived glycoprotein fetuin-A...

INTRODUCTION: Anemia frequently occurs in chronic kidney disease (CKD), is associated with poor quality of life and cardiovascular outcomes, and its treatment represents a considerable economic burden to the healthcare system. Although effective, the current standard of care for the treatment of anemia in chronic kidney disease patients with erythropoiesis-stimulating agents requires chronic/ongoing injections, making the treatment less accessible or desirable to patients not treated by in-center maintenance hemodialysis...

The optimal SARS-CoV-2 vaccination schedule in dialysis patients and the potential need for a fourth vaccine dose are debatable. We prospectively assessed the humoral responses to three and four doses of BNT162b2 among dialysis patients. The study included 106 dialysis patients; 60 (56.6%) and 46 (43.4%) received 3 and 4 vaccine doses, respectively. Anti-spike (anti-S) antibody titers significantly increased after the third vaccine dose, followed by a decline, yet still remained higher than all previous measurements...

INTRODUCTION: Chronic activation of the mineralocorticoid receptor (MR) leads to pathological processes like inflammation and fibrosis during cardiorenal disease. Modulation of immunological processes in the heart or kidney may serve as a mechanistic and therapeutic interface in cardiorenal pathologies. In this study, we investigated anti-inflammatory/-fibrotic and immunological effects of the selective nonsteroidal MR antagonists finerenone (FIN) in the deoxycorticosterone acetate (DOCA)-salt model...

INTRODUCTION: Megalin plays an important role in proximal tubule uptake of filtered proteins. Downregulation and dysfunction of megalin were previously demonstrated in IgA nephropathy (IgAN); however, its relationship to IgAN progression remains unclear. METHODS: We measured renal megalin mRNA and miR-148b, previously identified as a regulator of megalin, in a retrospective cohort of 417 IgAN patients at the time of biopsy, and evaluated their associations with chronic kidney disease (CKD) progression event, defined as end-stage renal disease or ≥40% decline in estimated glomerular filtration rate, using Cox proportional hazard models...

INTRODUCTION: Obesity increases the risk of vitamin D insufficiency, which exacerbates secondary hyperparathyroidism in chronic kidney disease. Recent studies suggest that serum total 25-hydroxyvitamin D (25OHD) levels of ≥50 ng/mL are necessary to produce significant reductions in elevated parathyroid hormone levels in nondialysis patients. Data from real-world and randomized controlled trials (RCTs) involving these patients were examined for (1) relationships between vitamin D treatments and the achieved levels of serum 25OHD and between serum 25OHD and body weight (BW)/body mass index (BMI); and (2) the impact of BW/BMI on achieving serum 25OHD levels ≥50 ng/mL with extended-release calcifediol (ERC) treatment or vitamin D supplementation (cholecalciferol or ergocalciferol)...

BACKGROUND: The epidermal growth factor (EGF) is a globular protein that is generated in the kidney, especially in the loop of Henle and the distal convoluted tubule. While EGF is nonexistent or hardly detectable in plasma, it is present in normal people's urine. Until now, risk stratification and chronic kidney disease (CKD) diagnosis have relied on estimated glomerular filtration rate (eGFR) and urine albumin/creatinine ratio (uACR), both of which reflect glomerular function or impairment...
