Abstract Background: The incidence of sepsis is high among patients in the intensive care units (ICU) and acute kidney injury (AKI) is a common complication of sepsis that contributes to increased mortality. Thymosin beta-4 (Tβ4) is an actin-sequestering protein that can prevent inflammation and fibrosis in several tissues. However, its functions in septic AKI remain unknown.Methods: 98 consecutive hospitalized patients with confirmed sepsis were enrolled. Demographics, comorbidities, laboratory findings, and outcomes were collected and analyzed. Serum Tβ4 levels at ICU admission were measured and analyzed for evaluating the probability of AKI using the logistic regression. In addition, the effects of exogenous Tβ4 on kidney injury was also conducted in mice where a sepsis model was induced by lipopolysaccharide (LPS) intraperitoneal injection. Results: Of the 98 patients with sepsis, 47 (48%) developed AKI. Patients with hypertension, diabetes, higher body mass index (BMI) and Sequential Organ Failure Assessment (SOFA) score were more likely to develop AKI. Among patients with AKI, hemoglobin, and Tβ4 were significantly decreased. Multivariate analysis showed decreased Tβ4, high SOFA, and high BMI to be independent risk factors for AKI in patients with sepsis. The overall mortality rate of the 98 septic patients was 20.4%, and the mortality rate of those with AKI was 29.8%. Kaplan-Meier analysis demonstrated that patients with AKI had a significantly higher risk of death. In particular, increasing AKI severity was associated with an increased risk of death. Furthermore, exogenous Tβ4 could reduce renal apoptosis and attenuated renal dysfunction, as well as reducing systemic inflammatory response through the prevention of the activation of NF-κB pathway in the sepsis model.Conclusions: The combination of Tβ4, SOFA, and BMI could allow for timely detection of septic AKI. Exogenous Tβ4 could prevent kidney injury in sepsis.

Relevance. Acute kidney injury (AKI) is one of the leading causes of death worldwide. However, the epidemiology of AKI is not well understood. In Russia, toxic kidney damage plays a significant role in the nosological structure of AKI — 12.2%.Aim of study. To study the features of AKI in patients with acute chemical poisoning.Material and methods. We analyzed 26 case histories of patients with acute chemical poisoning with AKI (according to KDIGO). The comparison group included 25 patients with acute chemical poisoning without AKI. All patients were hospitalized in a toxicological center on the basis of the emergency department of the Ryazan Region State Budgetary Institution “City Clinical Emergency Hospital” (SBI RR “CCH EMC”) in 2016–2018. The analysis of the annual reports of the chief toxicologist of the Ministry of Health of the Ryazan Region for 2016–2018 was carried out. Data processing was performed using Microsoft Office Excel 2013 and on the website medstatistic.ru (Pearson’s chi-square test and Fisher’s exact test).Results. In most patients AKI developed during poisoning with cauterizing action substances - 38.4% (23% - vinegar essence, 15.4% - unidentified cauterizing action substance). The poisoning with alcohol substitutes (12%) took the 2nd place, with narcotic substances (8%) – the 3 rd place. Also, isolated cases of AKI (4% each) were reported in case of poisoning with pregabalin, tramadol, ketorol and ethanol. Poisoning with an unknown toxicant was noted in 29.6% of cases. Most patients (69.2%.) had stage 3 AKI. The second stage was registered in 7.7% of patients, the first — in 23.1%. Proteinuria was detected in all patients who underwent common urine test (CUT). Infusion therapy using crystalloids was performed in 100% of cases.Conclusion. Acute renal injury most often develops in acute poisoning with cauterizing poisons. The development of acute kidney injury in acute chemical poisoning leads to an increased risk of death. Acute kidney injury is the second most common immediate cause of death in acute chemical poisoning. Infusion therapy is an integral part of the management of toxicological patients with acute kidney injury.

<b><i>Introduction:</i></b> Acute kidney injury (AKI) is strongly associated with poor outcomes in hospitalized patients with coronavirus disease 2019 (COVID-19), but data on the association of proteinuria and hematuria are limited to non-US populations. In addition, admission and in-hospital measures for kidney abnormalities have not been studied separately. <b><i>Methods:</i></b> This retrospective cohort study aimed to analyze these associations in 321 patients sequentially admitted between March 7, 2020 and April 1, 2020 at Stony Brook University Medical Center, New York. We investigated the association of proteinuria, hematuria, and AKI with outcomes of inflammation, intensive care unit (ICU) admission, invasive mechanical ventilation (IMV), and in-hospital death. We used ANOVA, <i>t</i> test, χ<sup>2</sup> test, and Fisher’s exact test for bivariate analyses and logistic regression for multivariable analysis. <b><i>Results:</i></b> Three hundred patients met the inclusion criteria for the study cohort. Multivariable analysis demonstrated that admission proteinuria was significantly associated with risk of in-hospital AKI (OR 4.71, 95% CI 1.28–17.38), while admission hematuria was associated with ICU admission (OR 4.56, 95% CI 1.12–18.64), IMV (OR 8.79, 95% CI 2.08–37.00), and death (OR 18.03, 95% CI 2.84–114.57). During hospitalization, de novo proteinuria was significantly associated with increased risk of death (OR 8.94, 95% CI 1.19–114.4, <i>p</i> = 0.04). In-hospital AKI increased (OR 27.14, 95% CI 4.44–240.17) while recovery from in-hospital AKI decreased the risk of death (OR 0.001, 95% CI 0.001–0.06). <b><i>Conclusion:</i></b> Proteinuria and hematuria both at the time of admission and during hospitalization are associated with adverse clinical outcomes in hospitalized patients with COVID-19.

Background: Literature regarding the outcomes of lower dosage peritoneal dialysis (PD) in treating acute kidney injury (AKI) among resource-limited setting is sparse. This study aims to compare the risk of mortality in patients with AKI receiving lower PD dosage and conventional intermittent hemodialysis (IHD) in Thailand. Methods: In a tertiary center in Thailand, a matched case–control study using propensity scores in patients with AKI was conducted to compare the outcomes between lower PD dosage (18 L per day for first two sessions, weekly Kt/ V 2.2) and IHD (three times a week) from February 2015 to January 2016. The primary outcome was a 30-day in-hospital mortality rate. Secondary outcomes included dialysis dependence at 90 days. Results: Eighty-four patients were included (28 PD and 56 IHD). Patient characteristics were comparable between two treatment groups. Overall, the mean age was 58 years. Most of the patients were critically ill (87% need mechanical ventilator; mean acute physiological and chronic health evaluation (APACHE II) score: 25). The 30-day in-hospital mortality rate was similar between the PD and IHD patients (57% vs. 46%, p = 0.36). The dialysis dependence rate was also comparable at 90 days. The risk of death among AKI patients was higher in those with respiratory failure, higher APACHE II score, and starting dialysis with blood urea nitrogen greater than 70 mg dL−1. Conclusion: Clinical outcomes, including risk of mortality and 90-day dialysis dependence among patients with AKI, appear to be comparable between lower dosage PD and IHD.

Acute kidney injury (AKI) is common in critically ill patients and is associated with higher mortality. Cancer patients are at an increased risk of AKI. Our objective was to determine the incidence of AKI in our critically ill cancer patients, using the criteria of serum creatinine (SCr) and urine output (UO) proposed by the Kidney Disease: Improving Global Outcomes (KDIGO).Methods.We performed a retrospective cohort analysis of a prospectively collected database at the intensive care unit (ICU) of the Instituto Nacional de Cancerología from January 2013 to March 2015.Results.We classified AKI according to the KDIGO definition. We included 389 patients; using the SCr criterion, 192 (49.4%) had AKI; using the UO criterion, 219 (56.3%) had AKI. Using both criteria, we diagnosed AKI in 69.4% of patients. All stages were independently associated with six-month mortality; stage 1 HR was 2.04 (95% CI 1.14–3.68,p=0.017), stage 2 HR was 2.73 (95% CI 1.53–4.88,p=0.001), and stage 3 HR was 4.5 (95% CI 2.25–8.02,p<0.001). Patients who fulfilled both criteria had a higher mortality compared with patients who fulfilled just one criterion (HR 3.56, 95% CI 2.03–6.24,p<0.001).Conclusion.We diagnosed AKI in 69.4% of patients. All AKI stages were associated with higher risk of death at six months, even for patients who fulfilled just one AKI criterion.

Abstract Abstract 819 Recently we reported that an excessive anticoagulation with warfarin (INR>3.0) can result in acute kidney injury (AKI). Morphologic findings included glomerular hemorrhage and renal tubular obstruction by red blood cell (RBC) casts. The clinical outcome in these patients was unfavorable; more than half of them did not recover from acute kidney injury even after normalization of INR. Later we analyzed serum creatinine (SC) and INR in patients with chronic kidney disease (CKD) on warfarin therapy. We found that 46% of patients had increase in SC levels >0.3 mg/dl associated with INR>3.0. SC remained elevated above baseline after the first episode of abnormal INR. The slope of the following SC increase was higher after this abnormal INR episode. We called this condition warfarin related nephropathy (WRN). The current study is based on medical records of 4059 consecutive patients who were on warfarin therapy at the Ohio State Medical Center for a 5-year period. Of these, 838 (21%) experienced an increase in SC>0.3 mg/dl within 1 week after INR>3.0 (WRN group). The remaining 3221 patients (79%) were designated no-WRN. The WRN group had a 5-year mortality rate of 42%, as compared to 27% for the no-WRN group (p<.001). The highest risk of death in the WRN cohort occurred within the 1st month after INR>3.0 (hazard ratio =2.15). For both WRN and no-WRN groups, the 5-year mortality rate was consistently higher in those with CKD compared to those with no-CKD (50.8% vs. 37.0% for the WRN cohort; 39.7% vs. 24.5% for the no-WRN cohort; p<.0001). Compared to no-WRN patients, WRN patients tended to be older (63.7±14.7 years vs. 61.7±15.6 years, p=.025), diabetic (47% vs 37%, p<.0001), hypertensive (82% vs 72%, p<.001) and had a history of heart failure (62% vs 42%, p<.001). Preliminary models indicate that WRN still is a significant predictor of death even after adjusting for these factors. We conclude that WRN is associated with increased mortality rate in the elderly, the diabetic, and those with CKD and cardiovascular diseases. The possible pathophysiologic mechanisms may be glomerular hematuria and formation of occlusive RBC casts. Physicians, involved in the clinical care of patients on systemic anticoagulation therapy, should be aware of this serious renal complication of warfarin overdose and carefully monitor the kidney function and coagulation parameters in these patients Disclosures: No relevant conflicts of interest to declare.

Background Acute kidney injury is a common occurrence in intensive care unit patients with a reported incidence of 11-67% and is associated with an increased risk of death. In other patient populations, erythrocyte transfusion has been associated with increased risk of adverse outcomes including sepsis, multisystem organ dysfunction, and death. The purpose of this study was to determine the effect of erythrocyte transfusion on the development of acute kidney injury. Methods This was a retrospective analysis of prospectively collected data that used propensity matched transfused and nontransfused patients. Propensity matching was done using semiparsimonious logistic regression. McNemar test for nonindependent data sets was used to compare groups. Results Four hundred two patients from a trial on fluid management in patients with acute lung injury were matched. 38% of transfused patients had a rise in creatinine the day after transfusion compared with 33% of their nontransfused matches (P = 0.315). By day 7, creatinine had increased in 51% of transfused patients compared with 52% in nontransfused patients (P = 0.832). The incidences of renal risk, injury, and failure were 39 (19%), 27 (13%), and 11 (5%) in the transfused group and 38 (19%), 24 (12%), and 11 (5%) in the nontransfused group, P = 1.00, 0.785, and 1.00, respectively. Conclusions Transfusion of erythrocytes to patients with acute lung injury had no effect on the development of acute kidney injury.
