Abstract Background Snakebite is a common occupational hazard in tropical countries. To date, the literature on snakebite-related acute kidney injury (AKI) has been limited by retrospective study designs, lack of uniformity in case definitions of AKI and limited follow-up. This study aims to identify the in-hospital outcomes and long-term changes in kidney function that follow haemotoxic envenomation. Methods All adult patients admitted with AKI following haemotoxic envenomation from January 2016 to June 2017 were recruited and followed up until July 2018. Predictors of in-hospital mortality was assessed. Long-term follow-up data on kidney function were collected from survivors. Results In total, 184 patients with haemotoxic envenomation and AKI were recruited. The mean age of the subjects was 42.2 years [95% confidence interval (CI) 40.3–44.7]. The majority were male (71.2%). The mortality of patients with haemotoxic envenomation was 21.5%. The mortality was considerably higher in patients with Kidney Disease: Improving Global Outcomes (KDIGO) Stage 3 AKI [relative risk (RR) 4.45 (95% CI 1.14–17.42)] and those who met KDIGO urine output criteria [RR 20.45 (95% CI 2.84–147.23)]. A Cox regression model identified mechanical ventilation [odds ratio (OR) 5.59 (95% CI 2.90–10.81)], hypotension [OR 2.48 (95% CI 1.31–4.72)] and capillary leak syndrome [OR 2.02 (95% CI 1.05–3.88)] as independent predictors of mortality. Long-term follow-up data were available for 73 patients. A total of 21 patients (28.7%) developed adverse renal outcomes (glomerular filtration rate <60 mL/min/1.73 m2, urine albumin excretion >30 mg/g and new-onset hypertension or prehypertension). Conclusions AKI resulting from snake envenomation is associated with considerable risk of mortality. The greater the AKI stage the greater the likelihood of mortality. One-third of patients with AKI developed long-term complications like chronic kidney disease, prehypertension and hypertension over the follow-up period.

BackgroundSnake bite continues to be a significant cause of acute kidney injury (AKI) in India. There is paucity of data regarding long-term outcomes of such patients. In this study, we aim to assess the prognosis and long-term renal outcomes of such patients.MethodsWe analysed the hospital records of snake envenomation-induced AKI from January 2015 to December 2018. Predictors of in-hospital mortality were assessed. Survivors were advised to visit follow-up clinic to assess their kidney function.ResultsThere were 769 patients with evidence of envenomation and of them, 159 (20.7%) had AKI. There were 112 (70.4%) males. Mortality occurred in 9.4% of patients. Logistic regression analysis identified shock (OR 51.949, 95% CI 4.297 to 628.072) and thrombocytopenia (OR 27.248, 95% CI 3.276 to 226.609) as predictors of mortality. Forty-three patients attended the follow-up. The mean follow-up duration was 30.4±15.23 months. Adverse renal outcomes (eGFR <60 mL/min/1.73 m2 or new-onset hypertension (HTN) or pre-HTN or urine protein creatinine ratio >0.3) occurred in 48.8% of patients. Older age (mean age (years) 53.3 vs 42.8, p=0.004) and longer duration on dialysis (median duration (days) 11.5 vs 5, p=0.024) were significantly associated with adverse renal outcomes.ConclusionsThe incidence of AKI in snake envenomation was 20.7%. The presence of shock and thrombocytopenia were associated with mortality. Adverse renal outcomes occurred in 48.8% of patients in the long term.

Acute kidney injury (AKI) is under-recognised in children and neonates. It is associated with increased mortality and morbidity along with an increased incidence of chronic kidney disease in adulthood. It is important that paediatricians are able to recognise AKI quickly, enabling prompt treatment of reversible causes. In this article, we demonstrate an approach to recognising paediatric AKI, cessation of nephrotoxic medication, appropriate investigations and the importance of accurately assessing fluid status. The mainstay of treatment is attempting to mimic the kidneys ability to provide electrolyte and fluid homeostasis; this requires close observation and careful fluid management. We discuss referral to paediatric nephrology and the importance of long-term follow-up. We present an approach to AKI through case-presentation.

Abstract Abstract 3463 Introduction: Chronic kidney disease (CKD) is common in survivors of hematopoietic stem cell transplantation (SCT). However, evolution over time of kidney dysfunction and its association with post-SCT acute kidney injury (AKI) are unclear. Methods: A retrospective cohort study was performed in 86 myeloablative allogenic SCT patients who received SCT between 1990 and 1999 and lived without relapse for 10 years or more. CKD was defined as a sustained decrease in estimated GFR less than 60 ml/min/1.73 m2 at least for a period more than 3 months. Post-SCT AKI was classified into three stages according to the acute kidney injury network (AKIN) criteria within 100 days after SCT. Incidence of new-onset CKD was studied by 1-year interval along the course of follow-up. Cumulative CKD incidence was evaluated by the Kaplan-Meier analysis. The factors associated with CKD at the time of 10 years after SCT were examined using Cox regression analysis. Results: The incident of new CKD was the highest (10.5%) at the first year after SCT and then remained almost constant (2.3 to 3.5%) (Figure 1). The prevalence of CKD increased along the follow-up time (Table 1). The cumulative incidence of CKD increased according to increasing AKI stages with significant difference between stages ≥1 and no AKI (Figure 2). Cox regression showed that each AKIN stage was a significant predictor of CKD: stage 3: hazard ratio (HR) 12.7, 95% confidence interval (CI) 2.42–97.6; stage 2: HR 7.75, 95% CI 1.83–53.6; and stage 1: HR 4.36, 95% CI 1.06–29.5. Other predictors included total body irradiation (TBI) (HR, 4.00; 95% CI, 1.63–10.5) and age on SCT (HR, 1.08; 95% CI, 1.03–1.13). Conclusions: CKD accumulated among long-term survivors receiving myeloablative allogenic SCT. Post-SCT AKI, regardless of the AKIN stages, is the most significant risk of CKD in such SCT population. Disclosures: No relevant conflicts of interest to declare.

Abstract Background This study was conducted to investigate whether acute kidney injury (AKI) is an independent predictor of anemia and whether anemia following AKI is a mediator of mortality after AKI. Methods This is a retrospective cohort study. Adults with noncardiac surgery from 2007 to 2011 were included. Obstetric or urological surgery, missing data or preoperative dialysis were excluded. Subjects were followed until the end of 2015 or lost to follow-up. Exposures of interest were postoperative AKI. Outcome variables were hematocrit values at 3, 6 and 12 months postoperatively and mortality. Associations between AKI and hematocrit or association between AKI and mortality were examined by multivariable linear regression or Cox regression, respectively. Results Among 6692 subjects, 445 (6.6%) developed AKI. Among those with postoperative data, AKI was independently associated with lower hematocrit at 3, 6 and 12 months postoperatively, with coefficients of −0.79 [95% confidence interval (CI) −1.47 to −0.11; n = 1750], −1.35 (−2.11 to −0.60; n = 1558) and −0.91 (−1.59 to −0.22; n = 2463), respectively. Higher stages or longer duration of AKI were associated with more severe anemia. AKI was associated with higher mortality after 3 months postoperatively with a hazard ratio of 1.54 (95% CI 1.12–2.12). Further adjustment with hematocrit at 3 months attenuated the association. The mediation effect was significant (P = 0.02) by mediation analysis. Conclusions AKI was an independent predictor of anemia following AKI. Higher mortality associated with AKI was at least partially mediated by anemia following AKI. Whether correction of anemia following AKI improves mortality requires further research.

Introduction. Contrast-induced acute kidney injury (CI-AKI) is a worldwide known complication related to the use of contrast media with either imaging or angiography; it carries its own complications and effect on both morbidity and mortality; early identification of patients at risk and addressing modifiable risk factors may help reducing risk for this disease and its complications. Methods. This was a prospective observational study, where all patients admitted for cardiac catheterization between June 2015 and January 2016 were evaluated for CI-AKI. There were two study groups: contrast-induced acute kidney injury (CI-AKI) group, and noncontrast-induced acute kidney injury (non-CI-AKI) group. Results. Patients ( n = 202 ) were included and followed up for 4 years. Death and development of chronic kidney disease (CKD) need for another revascularization were the end points. The incidence of CI-AKI was 14.8%.In univariate analysis, age ( P = 0.016 ) and serum albumin at admission ( P = 0.001 ) were statistically significant predictors of overall death. Age ( P = 0.002 ), HTN ( P = 0.002 ), DM ( P = 0.02 ), and the use of diuretics ( P = 0.001 ) had a statistically significant impact on eGFR. The rate of recatheterization was not statistically significant between the two groups (61 (35.5%) for the non-CI-AKI vs. 12 (40%) for the other group; P = 0.63 ). Some inflammatory markers (NGAL P = 0.06 , IL-19 P = 0.08 ) and serum albumin at admission P = 0.07 had a trend toward a statistically significant impact on recatheterization. Death ( P = 0.66 ) and need for recatheterization ( P = 0.63 ) were not statistically different between the 2 groups, while the rate of eGFR decline in for the CI-AKI was significant ( P = 0.004 ). Conclusion. CI-AKI is a common complication post percutaneous catheterization (PCI), which may increase the risk for CKD, but not death or the need for recatheterization. Preventive measures must be taken early to decrease the morbidity.

Recent research has provided important insights on the long-term outcomes of patients who develop acute kidney injury (AKI) in the setting of critical illness. Large epidemiologic studies have demonstrated compelling associations between episodes of AKI and progressive kidney disease and death, respectively, although such studies do not establish causality due to the potential for confounding. Whether AKI is intrinsically toxic or a mere by-product of serious comorbidities (e.g. prior chronic kidney disease, heart failure, diabetes), there is no doubt that AKI survivors are a high-risk group who would likely benefit from close post-discharge follow-up. Recent studies have shown that a minority of patients with AKI receive specialized nephrology follow-up after discharge, suggesting an opportunity for quality improvement. Emerging research is evaluating factors that predict chronic kidney disease, end-stage renal disease, and death among AKI survivors. This work will, it is hoped, suggest new targets for prevention and treatment, with the goal of enhancing the likelihood of recovery following AKI.

Abstract Background and Aims The current diagnostic criteria for acute kidney injury (AKI) predict the need for dialysis and early mortality, but are less useful to predict long-term outcomes. Acute kidney disease (AKD) defines patients with AKI or subacute loss of kidney function lasting for more than 7 days, which should predict better subsequent chronic kidney disease (CKD). The aim of this study was to investigate the risk factors and prognosis of AKD and to compare different types of acute/subacute renal impairment among Chinese inpatients. Method From a cohort of 450,000 patients consecutive admitted from June 1, 2012, to March 31, 2018 to five district hospitals, complete data were available from 71,041 inpatients. AKI and AKD were diagnosed based on the Acute Disease Quality Initiative Criteria 2017. Based on this diagnostic criterion of AKI and AKD, patients were classified as having (1) AKI Recover, if Scr back to baseline value within 7 days (renal impairment duration of less than 7 days or rapid recovery within 7 days), and (2) AKD with AKI, if a condition in which stage 1 or greater AKI was present ≥ 7 days after an AKI initiating event (continuous AKI progressing to AKD), (3) AKD without AKI, if Scr levels increased slowly but lasted more than 7 days (subacute AKD without meeting the AKI criterion). Results Of 71,041 inpatients, 16,098 (22.66%) patients developed AKI or AKD. 5,895 (8.30%) AKI patients recovered within 7 days (AKI Recover), 5,623 (7.91%) were followed by AKD and 4,580 (6.44%) patients developed AKD without AKI. Thus, AKI and AKD are frequent complications in Chinese inpatients (Fig 1). Compared to AKI recover or AKD without AKI, patients with AKI followed by AKD had higher hospital mortality (16.59% vs. 3.82% vs. 2.12%, P&lt;0.05) and more de novo CKD (8.95% vs. 7.29% vs. 5.48%, P&lt;0.05). Mortality was proportional to stages of AKI and AKD (P for trend &lt;0.05), while AKI followed by AKD was associated with a higher risk of long-term mortality (hazard ratio (HR) 4.51, 4.32-4.71, P&lt;0.05) as compared to AKD without AKI (HR 2.25, 2.13-2.39, P&lt;0.05) and AKI Recover (HR 1.18, 1.09-1.26, P&lt;0.05). The AKI criterion yielded a higher risk for overall survival and a lower risk for de novo CKD than the AKD criterion, indicating that both criteria imply persistent kidney damage but that a rapid decline in excretory kidney function implies higher mortality risks while a persistent decline may rather result in de novo CKD (Fig 2). Meanwhile, these associations between different kidney injury criteria and outcomes had good generalizability and were constant across different genders, surgeries, and comorbidities (Fig 2). The AKD criterion was robustly associated with overall survival (area under the receiver operating characteristic curve (AUROC) 0.71) and de novo CKD (AUROC 0.71), while AKI criterion showed a relatively lower ability to fitting risk of overall survival (AUROC 0.65, P&lt;0.05) and CKD (AUROC 0.63, P&lt;0.05). Moreover, combining AKI and AKD was strongly associated with long-term mortality (AUROC 0.725) and de novo CKD (AUROC 0.72) compared to each single criterion of AKI or AKD (Fig 3). Conclusion (1) Adding AKD as a definition for renal failure lasting &gt;7 days up to 90 days is of clinical importance in addition to the existing definitions for AKI and CKD. (2) These findings suggest research activities and clinical practice should also focus on AKD, which is far more accurate to predict subsequent de novo CKD.
