- How should we treat acute kidney injury caused by renal congestion?
- Masanori Abe, Seiichiro Hemmi, Hiroki Kobayashi
- Received September 30, 2022 Accepted October 29, 2022
-
Decreased kidney function is associated with increased risk of cardiovascular events and mortality, and heart failure (HF) is a well-known risk factor for renal dysfunction. Acute kidney injury (AKI) in patients with HF often is attributed to prerenal factors, such as renal hypoperfusion and ischemia as a result of decreased cardiac output. Another such factor is reduction of absolute or... -

- Histologic evaluation of activity and chronicity of lupus nephritis and its clinical significance
- Sung-Eun Choi, Agnes B. Fogo, Beom Jin Lim
- Received April 23, 2022 Accepted May 8, 2022
-
The National Institutes of Health (NIH) lupus nephritis activity and chronicity indices, which comprise six activity scores and four chronicity scores, have a long development history. The 2018 revised International Society of Nephrology/Renal Pathology Society (ISN/RPS) classification for lupus nephritis adopted the most recent NIH indices to replace subclasses A, C, and A/C. Although an evidence-based approach should further evaluate... -

Recent technical advances in the detection of backscattered electrons during scanning electron microscopy (SEM) have improved resolution and have provided several new technologies for research and clinical practice in kidney disease. The advances include three-dimensional (3D) electron microscopy (3D-EM), correlative light and electron microscopy (CLEM), low-vacuum SEM (LVSEM), and scanning transmission electron microscopy (STEM). 3D-EM analysis used to be laborious,... -

Background: The 2009 Chronic Kidney Disease Epidemiology Collaboration creatinine-based estimated glomerular filtration rate (eGFRcr) equation contains a race component that is not based on biology and may cause a bias in results. Therefore, the 2021 eGFRcr and creatinine-cystatin C–based eGFR (eGFRcr-cysC) equations were developed with no consideration of race. This study compared the cardiovascular event (CVE) and all-cause mortality and... -

- Youn Kyung Kee, Hee Jung Jeon, Jieun Oh, Dong Ho Shin
- Received July 11, 2022 Accepted October 18, 2022
-
Background: In addition to improving the serum vitamin D balance, narrowband ultraviolet B (NB-UVB) phototherapy can effectively treat chronic kidney disease-associated pruritus (CKD-aP). We investigated the degree of CKD-aP amelioration according to changes in the serum vitamin D level after NB-UVB phototherapy. Methods: This was a before–after clinical study in patients with refractory CKD-aP on hemodialysis. NB-UVB phototherapy was administered thrice... -

Background: It is important for the dialysis specialist to provide essential and safe care to hemodialysis (HD) patients. However, little is known about the actual effect of dialysis specialist care on the survival of HD patients. We therefore investigated the influence of dialysis specialist care on patient mortality in a nationwide Korean dialysis cohort. Methods: We used an HD quality assessment... -

Background: Despite efforts to treat critically ill patients who require continuous renal replacement therapy (CRRT) due to acute kidney injury (AKI), their mortality risk remains high. This condition may be attributable to complications of CRRT, such as arrhythmias. Here, we addressed the occurrence of ventricular tachycardia (VT) during CRRT and its relationship with patient outcomes. Methods: This study retrospectively enrolled... -

- The flavonoid fisetin ameliorates renal fibrosis by inhibiting SMAD3 phosphorylation, oxidative damage, and inflammation in ureteral obstructed kidney in mice
- Ha Young Ju, Jongwan Kim, Sang Jun Han
- Received February 15, 2022 Accepted June 28, 2022
-
Background: Renal fibrosis is characterized by the accumulation of extracellular matrix and inflammatory cells and kidney dysfunction, which is a major pathway in the progression of chronic kidney disease (CKD). Accumulating evidence indicates that oxidative stress plays a critical role in the initiation and progression of CKD via proinflammatory and profibrotic signaling pathways. Fisetin (3,3′,4′,7-tetrahydroxyflavone) has biological activities including antioxidant,... -

Background: Diminazene aceturate (DIZE), an angiotensin-converting enzyme 2 (ACE2) activator, exerts anti-inflammatory and antifibrotic effects in a variety of human chronic diseases. However, the role of DIZE in kidney fibrosis and the underlying mechanism remain unclear. Therefore, we investigated the effects of DIZE on the progression of renal fibrosis after unilateral ureteral obstruction (UUO), a well-established model of chronic kidney... -

Background: T50 is a novel serum-based marker that assesses the propensity for calcification in serum. A shorter T50 indicates a greater propensity to calcify and has been associated with cardiovascular disease and mortality among patients with chronic kidney disease. The factors associated with T50 and the correlation between T50 and bone mineral density (BMD) are unknown in hemodialysis (HD) patients.... -
