BACKGROUND: Acute kidney injury (AKI) after robot-assisted partial nephrectomy (RAPN) is a robust surrogate for chronic kidney disease. The objective of this study was to evaluate the association of ischemia type and duration during RAPN with postoperative AKI. MATERIALS AND METHODS: We reviewed all patients who underwent RAPN at our institution since 2011. The ischemia types were warm ischemia (WI), selective artery clamping (SAC), and zero ischemia (ZI). AKI was defined according to the Risk Injury Failure Loss End-Stage (RIFLE) criteria. We calculated ischemia time thresholds for WI and SAC using the Youden and Liu indices. Logistic regression and decision curve analyses were assessed to examine the association with AKI. RESULTS: Overall, 154 patients met the inclusion criteria. Among all RAPNs, 90 (58.4%), 43 (28.0%), and 21 (13.6%) were performed with WI, SAC, and ZI, respectively. Thirty-three (21.4%) patients experienced postoperative AKI. We extrapolated ischemia time thresholds of 17 min for WI and 29 min for SAC associated with the occurrence of postoperative AKI. Multivariable logistic regression analyses revealed that WIT ≤ 17 min (odds ratio [OR] 0.1, p < 0.001), SAC ≤ 29 min (OR 0.12, p = 0.002), and ZI (OR 0.1, p = 0.035) significantly reduced the risk of postoperative AKI. CONCLUSIONS: Our results confirm the commonly accepted 20 min threshold for WI time, suggest less than 30 min ischemia time when using SAC, and support a ZI approach if safely performable to reduce the risk of postoperative AKI. Selecting an appropriate ischemia type for patients undergoing RAPN can improve short- and long-term functional kidney outcomes.

The coronavirus disease 2019 (COVID-19) pandemic has disproportionately affected patients with kidney disease, causing significant challenges in disease management, kidney research and trainee education. For patients, increased infection risk and disease severity, often complicated by acute kidney injury, have contributed to high mortality. Clinicians were faced with high clinical demands, resource shortages and novel ethical dilemmas in providing patient care. In this review, we address the impact of COVID-19 on the entire spectrum of kidney care, including acute kidney injury, chronic kidney disease, dialysis and transplantation, trainee education, disparities in health care, changes in health care policies, moral distress and the patient perspective. Based on current evidence, we provide a framework for the management and support of patients with kidney disease, infection mitigation strategies, resource allocation and support systems for the nephrology workforce.

BACKGROUND: To analyze postoperative, in-hospital, complication rates in patients with organ transplantation before radical prostatectomy (RP). METHODS: From National Inpatient Sample (NIS) database (2000-2015) prostate cancer patients treated with RP were abstracted and stratified according to prior organ transplant versus nontransplant. Multivariable logistic regression models predicted in-hospital complications. RESULTS: Of all eligible 202,419 RP patients, 216 (0.1%) underwent RP after prior organ transplantation. Transplant RP patients exhibited higher proportions of Charlson comorbidity index ≥2 (13.0% vs. 3.0%), obesity (9.3% vs. 5.6%, both p < 0.05), versus to nontransplant RP. Of transplant RP patients, 96 underwent kidney (44.4%), 44 heart (20.4%), 40 liver (18.5%), 30 (13.9%) bone marrow, <11 lung (<5%), and <11 pancreatic (<5%) transplantation before RP. Within transplant RP patients, rates of lymph node dissection ranged from 37.5% (kidney transplant) to 60.0% (bone marrow transplant, p < 0.01) versus 51% in nontransplant patients. Regarding in-hospital complications, transplant patients more frequently exhibited, diabetic (31.5% vs. 11.6%, p < 0.001), major (7.9% vs. 2.9%) cardiac complications (3.2% vs. 1.2%, p = 0.01), and acute kidney failure (5.1% vs. 0.9%, p < 0.001), versus nontransplant RP. In multivariable logistic regression models, transplant RP patients were at higher risk of acute kidney failure (odds ratio [OR]: 4.83), diabetic (OR: 2.81), major (OR: 2.39), intraoperative (OR: 2.38), cardiac (OR: 2.16), transfusion (OR: 1.37), and overall complications (1.36, all p < 0.001). No in-hospital mortalities were recorded in transplant patients after RP. CONCLUSIONS: Of all transplants before RP, kidney ranks first. RP patients with prior transplantation have an increased risk of in-hospital complications. The highest risk, relative to nontransplant RP patients appears to acute kidney failure.

BACKGROUND: The evaluation of the predictive value of the neutrophil gelatinase-associated lipocalin (NGAL) for an early acute kidney injury (AKI) development in severely injured patients. Determination of the time-dependent roles of trauma-related physiologic markers of tissue hypoxia, systemic inflammation and rhabdomyolysis in AKI development. METHODS: 81 adult patients were screened for the presence of AKI for eight consecutive days following the injury. Arterial levels of plasma NGAL, lactate, interleukin-6, procalcitonin, and myoglobin were investigated at 24 hours (T1), 48 hours (T2), and 96 hours (T3) after the injury. RESULTS: The incidence of AKI was 32.1 %. Patients with AKI were older, but no significant difference in injury severity was observed. NGAL levels were significantly higher in the AKI group at T1, T2, and T3 when compared to the non-AKI group. Lactate levels were significantly higher in the AKI group at T2 only, and IL-6 levels were significantly higher in the AKI group at T2 and T3. Procalcitonin and myoglobin levels were significantly higher in the AKI group at T1, T2, and T3, when compared to the non-AKI group. Positive correlations were found between plasma NGAL and all screened physiological factors at all defined time points. CONCLUSION: Development of AKI after blunt trauma is very complex and multifactorial. Activation of the systemic inflammatory response and rhabdomyolysis (high concentration of myoglobin) were strongly involved in AKI development. Blood NGAL levels after injury were significantly higher in patients, who developed posttraumatic AKI. Plasma NGAL, lactate, procalcitonin, interleukin-6, and myoglobin had potential to be useful parameters for risk stratification and prediction of AKI after trauma (Tab. 6, Ref. 40).

BACKGROUND/AIMS: The rate of incidence and prevalence of acute kidney injury is increasing due to an increased number of patients with heart failure. Therefore it is very pertinent to early detect the level of renal injuries and to make necessary heart failure predictions. Thus the aim of this study is to determine renal functions and prognosis stratification in chronic heart failure patients and importance of Neutrophil Gelatinase-Associated Lipocalin (NGAL), an early diagnostic marker of acute kidney injury, as well as stratification of cardiovascular risk in heart failure patients. METHODS: Data including age, gender, comorbidities and medical history of outpatients and hospitalized patients from Farmacology and NeuroHumoraL activation (FAR NHL) multicenter prospective registry comprising three Cardiological Centers in the Czech Republic were collected between 1st October 2014 and 30th November 2015. One-year follow-up data were collected in November 2016 in such a way that all patients had at least one-year data from the time of recruitment, but up to two years to the time of follow-up. One-year data were used for the whole set of patients while data up to 24 months were used with Kaplan-Meier's survival curves to analyse the patients' survival data. Blood samples were collected from the patients and basic parameters were evaluated in order to analyse Neutrophil gelatinase-associated lipocalin (NGAL) and plasma levels of N-terminal pro-brain natriuretic peptide (NT-ProBNP) using Lipocalin-2/NGAL Human ELISA kit (Bio Vendor, Czechia) and the Cobas E411 NT-proBNP Immunoassay kit (Roche Diagnostics, Indianapolis, IN, USA) respectively. Statistical analysis was further carried out to explain the level of significance of the evaluated parameters using Spearman Correlation, Mann Whitney or Kruskal-Wallis test and log-rank test. RESULTS: Out of 547 patients from Farmacology and NeuroHumoraL activation (FAR NHL) multicenter prospective registry with available data on hospitalizations, mortality, biomarkers and one-year follow-up that were recorded, there were 439 males (80.3%) with a median age of 66 years. At least one-month stable patients with left ventricle ejection fraction (LV EF) under 50% were recorded. The etiology of heart failure was ischemic heart disease in 54%, dilated cardiomyopathy in 40% and others in 6%. 69% patients were in New York Heart Association functional class II. There were 76 events (13.9%; all-cause mortality, acute heart failure hospitalization, left ventricle assist device implantation and orthotopic heart transplant) in the first 365 days of follow-up. The area under the receiver operating characteristic curve was higher for NT-proBNP (0.77) than the creatinine (0.57), NGAL (0.55) or creatinine clearance (0.54). In multivariable analyses, NT-proBNP (P= 0.001) and NGAL (P = 0.004) were significant predictors of events. Subjects with NT-proBNP and NGAL above the cut off value (NT-proBNP 1,121 pg/ml, NGAL 80 ng/ml) survived without any event in 55.7%, subjects with NT-proBNP and NGAL under the cut off value survived without any event in 90.5%, after two years (P = 0.001). CONCLUSION: The findings of the study showed that NGAL associated with NT-proBNP was a stronger predictor of the primary endpoint than NGAL or NT-proBNP alone. The level of NGAL was rising in hypertension, ischemia, anemia, hypoalbuminemia, diabetes or arrhythmias.

OBJECTIVE: We aimed at assessing the predictive value of plasmatic Neutrophil Gelatinase Associated Lipocalin (pNGAL) at admission and severity scores to predict major adverse kidney events (MAKE, defined as death and/or need for renal replacement therapy (RRT) and/or non-renal recovery at day 90) in critically ill burn patients. MATERIAL AND METHODS: Single-center cohort study in a burn critical care unit in a tertiary center, including all consecutive severely burn patients (total burned body surface >20%) from January 2012 until January 2015 with a pNGAL dosage at admission. Reclassification of patients was assessed by Integrated Discrimination Improvement (IDI). MEASUREMENTS AND RESULTS: 87 patients were included. Mean age was 47.7 (IQ 25-75: 33.4-65.2) years; total burn body surface area was 40 (IQ 25-75: 30-55) % and ICU mortality 36%. 39 (44.8%) patients presented a MAKE, 32 (88.9%) patients died at day 90. pNGAL was higher in the MAKE group (423 [IQ 25-75: 327-518]pg/mL vs 184 [IQ 25-75: 147-220]pg/mL, p<0.001). In multivariate analysis, pNGAL and abbreviated burn severity index (ABSI) remained associated with MAKE (OR 1.005 [CI 95% 1.0005-1.009], p=0.03 and OR 1.682 [CI95%1.038-2.726], p=0.035 respectively). Adding pNGAL to abbreviated burn severity index, simplified organ failure assessment and the simplified acute physiology score 2 did outperform clinical scores for the prediction of MAKE and AKI and for most severe forms of AKI and allowed a statistically significant reclassification of patients compared to ABSI for MAKE, RRT, AKI at Day 7 and AKI during hospitalization with a number of patients needed to screen to detect one extra episode of MAKE was 44, 13 for severe AKI and 15 for AKI. CONCLUSIONS: pNGAL at admission is associated with the risk of MAKE in this population, and outperform severity scores when associated. Interventional studies are now needed to assess if impact of biomarkers-guided strategies would improve outcome.

Poškození ledvin patří k častým komplikacím farmakoterapie ambulantních i hospitalizovaných pacientů. Ačkoli jde většinou o stav, který probíhá zcela asymptomaticky se spontánním odezněním bez vzniku závažných následků, může vést v některých případech k dočasné nebo trvalé ztrátě renální funkce a nutnosti náhrady funkce ledvin. Zejména u hospitalizovaných pacientů je akutní poškození ledvin spojeno s vysokou morbiditou a mortalitou. Toto sdělení podává ucelený přehled o možné nefrotoxicitě běžných antiinfektiv z hlediska potřeb praktického lékaře.
Kidney injury is among frequent complications of pharmacotherapy in both outpatients and inpatients. Although it most often isa condition that is usually asymptomatic and resolves spontaneously without developing serious sequelae, in some cases it maylead to temporary or permanent loss of renal function and the need for replacement of renal function. In hospitalized patients,in particular, acute kidney injury is associated with high morbidity and mortality. This paper presents a review of potential nephrotoxicityof common anti-infective agents with respect to the needs of a specialist in outpatient practice.
