Asymptomatic hyperuricemia is frequently observed in patients with kidney disease. Although a substantial number of epidemiologic studies have suggested that an elevated uric acid level plays a causative role in the development and progression of kidney disease, whether hyperuricemia is simply a result of decreased renal excretion of uric acid or is a contributor to kidney disease remains a matter of debate. Over the last two decades, multiple experimental studies have expanded the knowledge of

Diabetic kidney disease (DKD) has been the leading cause of chronic kidney disease for over 20 years. Yet, over these two decades, the clinical approach to this condition has not much improved beyond the administration of glucose-lowering agents, renin-angiotensin-aldosterone system blockers for blood pressure control, and lipid-lowering agents. The proportion of diabetic patients who develop DKD and progress to end-stage renal disease has remained nearly the same. This unmet need for DKD treatm

Primary Sjögren's syndrome (pSS) is characterized by lymphocytic infiltration of the exocrine glands resulting in decreased saliva and tear production. It uncommonly involves the kidneys in various forms, including tubulointerstitial nephritis, renal tubular acidosis, Fanconi syndrome, and rarely glomerulonephritis. Its clinical symptoms include muscle weakness, periodic paralysis, and bone pain due to metabolic acidosis and electrolyte imbalance. Herein, we describe the cases of two women with

BACKGROUND: Post-transplant malignancy is major morbidity complicated in kidney transplantation (KT). In Korea, a few studies have investigated the sex- and age-dependent risk for post-transplant malignancy among KT recipients on a large scale. METHODS: We utilized a national health insurance database in Korea to investigate the relative risk of post-transplant malignancy in 12,634 KT recipients between 2007 and 2017. The same number of patients with acute appendicitis was included as a control

BACKGROUND: Urine exosomal bkv-miR-B1-5p is associated with BK virus (BKV) nephropathy (BKVN); however, its posttransplantation changes and predictability for BKVN have not been determined in kidney transplant recipients (KTRs). METHODS: Urine exosomal bkv-miR-B1-5p and urine and plasma BKV DNA were measured at 2 weeks and 3, 6, and 12 months posttransplant in 83 KTRs stratified into biopsy-proven or presumptive BKVN, BKV viruria, and no evidence of BKV reactivation. Joint model, multivariable C

Urticarial vasculitis is a rare disorder that principally manifests with recurrent urticarial, sometimes hemorrhagic, skin lesions and/or angioedema. Its clinical presentation is not always limited to cutaneous lesions and it can potentially affect other organs, such as the joints, lungs, kidneys, and eyes. Systemic involvement can either be present at the onset of disease or develop over time. In cases with systemic manifestations, urticarial vasculitis is more likely to be associated with a lo

The transition of fibroblasts into myofibroblasts is a crucial step in kidney fibrosis. However, the biological processes involved in this transdifferentiation are incompletely understood. In this study, we discovered that the midbody plays a role in the fibroblast-myofibroblast transition by mediating TGF-β/Smad signaling. Combining bulk RNA-seq, histology, and the western blot of unilateral ureteral obstruction kidneys, we demonstrated that the pathway related to microtubules is implicated in

Renal aging is a natural process that can lead to structural changes and functional decline in the kidneys. These age-related changes are considered irreversible physiological processes, but resemble diseased kidneys. To enhance understanding of the molecular nature of renal aging, we first compared whole-kidney RNA sequencing between naturally aging mice (24-month-old) and adenine-induced nephropathy in young mice (2-month-old). Young mice (2-month-old) without intervention were used as the con

BK virus is ubiquitous worldwide, with infection usually occurring in early childhood. BK virus replicates prolifically under immunosuppressive conditions, causing inflammation along the genitourinary tract and progressing clinically to hemorrhagic cystitis, ureteral stenosis, and tubulointerstitial nephritis. Most BK virusassociated nephropathy occurs in renal allograft patients after kidney transplantation, although some case reports have described BK virus-associated nephropathy in the native

Clinical decision support systems (CDSSs) represent the latest technological transformation in healthcare for assisting clinicians in complex decision-making. Several CDSSs are proposed to deal with a range of clinical tasks such as disease diagnosis, prescription management, and medication ordering. Although a small number of CDSSs have focused on treatment selection, areas such as medication selection and dosing selection remained under-researched. In this regard, this study represents one of

Renal ischemia-reperfusion injury (IRI) is involved in the majority of clinical conditions that manifest as renal function deterioration; however, specific treatment for this type of injury is still far from clinical use. Since Toll-like receptor (TLR)-mediated signaling is a key mediator of IRI, we examined the effect of a multiple-TLR-blocking peptide named TLR-inhibitory peptide 1 (TIP1), which exerts the strongest action on TLR4, on renal IRI. We subjected C57BL/6 mice to 23 min of renal ped

Abnormalities in PBX1 represent a monogenic cause of congenital anomalies of the kidney and urinary tract (CAKUT). However, their phenotypic heterogeneity poses a challenge for timely detection, particularly in the absence of overt anomalies in the kidney and urinary tract. Here, we present a 28-year-old male diagnosed with a rare PBX1 nonsense variant identified during the evaluation of early-onset chronic kidney disease. As part of the initial workup for decreased renal function and proteinuri
