Purpose: Renal dysfunction is a common complication and one of the factors that affects the outcomes of liver transplantation (LT). The aim of this study was to review the clinical course of recipients of LT who needed peritransplant dialysis at our center., Methods: We compared the clinical demographics, morbidity, and mortality between patients who required and those who did not require peritransplant dialysis among 26 recipients of LT from May 2015 to February 2018 at our center., Results: Among the recipients, 9 had pretransplant or posttransplant dialysis and 17 did not. The patients who underwent dialysis had a higher pretransplant Model for End-Stage Liver Disease score (42 vs 13; P < .001), older donor age (41 vs 24 years; P < .001), and longer post-LT hospital stay (37 vs 20 days; P < .001). However, there was no significant difference in the serum creatinine level between the 2 groups (1.36 vs 0.93 mg/dL; P = .187) at 2 weeks (1.10 vs 0.96 mg/dL; P = .341), 1 month (1.06 vs 0.86 mg/dL; P = .105), and 3 months after LT (0.92 vs 0.94 vs 0.89 mg/dL; P = .825). Mortality was higher in the peritransplant dialysis group (P = .043). The pre-LT dialysis duration was significantly related to post-LT dialysis (P = .028) and mortality (P = .011)., Conclusions: The pre-LT dialysis duration is considered an important factor in the survival and recovery of kidney function after LT. Therefore, if the patient has started dialysis, it may be beneficial to proceed to LT as soon as possible., (Copyright © 2019. Published by Elsevier Inc.)

Background:Several registries and centers have reported the results of renal biopsies from different parts of the world. As there are few data regarding the epidemiology of glomerulonephritis (GN) in South Korea, we conducted this study on renal biopsy findings during the last 20 years from a single center. Methods:Data for 818 patients who underwent renal biopsy at our center between 1992 and 2011 were collected retrospectively. All kidney specimens were examined with light microscopy (LM) and immunofluorescent microscopy (IF). Results:There were 818 cases of native kidney biopsies. In cases of primary GN, the most frequent type of renal pathology in adults (18–59 years) was mesangial proliferative GN (MsPGN, 34.5%) followed by IgA nephropathy (IgAN, 33.3%) and membranous GN (MGN, 8.8%). Indications in adults (18–59 years) were asymptomatic urinary abnormalities (75.3%) followed by nephrotic syndrome (19.8%) and acute kidney injury (AKI, 3.4%). Conclusions:Among 818 renal biopsy specimens, MsPGN and IgAN were the most frequent biopsy-proven renal diseases. MGN was the third most common cause of primary GN and lupus nephritis (LN) was the most common secondary glomerular disease. Our data contribute to the epidemiology of renal disease in South Korea.

Background/Aims: Aldosterone antagonists have been proven to be efficient in the management of hypertension and the reduction of proteinuria; however, they are not widely used because of the risk of hyperkalemia. We assessed the predictors of hyperkalemia risk following hypertension control using aldosterone blockade in the presence or absence of chronic kidney disease (CKD). Methods: A total of 6,575 patients with hypertension treated between January 1, 2000, and November 30, 2012, were evaluated for the safety of an aldosterone-blocking agent (spironolactone) added to preexisting blood pressure-lowering regimens. Hyperkalemia was defined as a serum potassium level ≥5.0 mEq/l. All patients used 3 mechanistically complementary antihypertensive agents, including a diuretic and a RAAS blocker. Patients were evaluated after 4 and 8 weeks of treatment. The incidence of hyperkalemia, significant renal dysfunction [a reduction of the estimated glomerular filtration rate (eGFR) ≥30%], and adverse effects was assessed. Results: The incidence of hyperkalemia in the presence or absence of CKD was 50.4 and 42.6% after 4 weeks (p = 0.001) and 3.8 and 3.0% after 8 weeks, respectively (p = 0.371). A logistic regression analysis revealed that medication, CKD, basal hyperkalemia, reduction in eGFR, and diabetes were all predictive of a hyperkalemia risk following spironolactone use. Conclusion: Spironolactone was well tolerated by selected CKD patients. The risk of serious hyperkalemia or a significant reduction of eGFR appears to be low. Strict monitoring over the first month of treatment followed by standard surveillance for angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers is suggested. © 2015 S.

Renal cortical necrosis (RCN) is a rare cause of acute kidney injury secondary to ischemic necrosis of the renal cortex. Acute tubular necrosis after binge drinking is usually attributed to volume depletion, idiosyncratic reaction to alcohol, rhabdomyolysis or a combination with non-steroidal anti-inflammatory drugs. Binge drinking itself as a cause of RCN has not yet been reported. We report a case of a 25-year-old Asian male who developed bilateral RCN following binge drinking. [ABSTRACT FROM AUTHOR]
