Abstract Background Leptospirosis is the most widespread zoonotic disease in the world. In India, it is endemic in coast lined states. Renal failure is a severe complication with mortality approaching 22%, early recognition of which helps clinicians in acting fast. This study aimed to investigate the predictors of Acute Kidney Injury (AKI) in Leptospirosis Methods This is a prospective, case–control study done in a tertiary care center in Southern India carried out between October 2017 and December 2018. Patients with confirmed Leptospirosis as per CDC 2013 and Faine’s criteria (2012) having AKI as per KDIGO criteria were defined as cases. Subjects without AKI were controls. Demographic, clinical and laboratory data were compared between the groups and analyzed. Logistic regression was performed to analyze the possible risk factors associated with AKI in Leptospirosis. Results A total of 329 subjects met the inclusion criteria of the study. 187 patients with AKI (CASES) and 142 patients without AKI (CONTROLS) were studied. Patients with AKI were older, (mean age- 46.99 ± 13.21 vs. 42.99 ± 15.15 years) had longer hospital stay (9.04 ± 5.62 vs. 6.27 ± 3.27 days) had higher SOFA (7.97 ±2.9 vs. 3.37 ± 2.6) and APACHE 2 scores (14.37±5.93 vs. 4.66 ± 4.4), lower mean arterial pressure (84.01 ± 14.45 vs. 89.01 ± 10.63 mmHg; P = 0.001) lower serum bicarbonate level (21.70 ± 2.35 vs. 18.73 ± 3.78 mEq/dL; P < 0.001). Factors like serum lactate, AST, ALT had no significant difference between the groups. Serovar identification was done in 88 patients, of which 57 had AKI. Australis (16.7%), Pyrogenes (16.7%) and Grippotyphosa (11.1%) were the commonest serovars isolated. Serovar most commonly associated with AKI was Pyrogenes (17.5%) Predictors for AKI were jaundice (P = 0.01, OR 2.25; CI 1.21 –3.26), vomiting (P = 0.017, OR 1.9, CI 1.12- 3.26) Hypotension (P = 0.02, OR = 12.3, CI 1.85 – 107.2), tachypnea (P = 0.006, OR = 2.55, CI 1.11- 3.24), leukocytosis (P < 0.001, OR 5.45, CI 1.86- 4.89), thrombocytopenia (P < 0.001, OR 6.49, CI 2.33 – 6.75) Conclusion Identification of features like hypotension, tachypnea, acidosis, leukocytosis, thrombocytopenia, the occurrence of serovar Pyrogenes should alert the clinician on risk of developing AKI Disclosures All authors: No reported disclosures.

Background: Postoperative Acute Kidney Injury (AKI) is a common and serious complication associated with significant morbidity and mortality. While several pre- and intra-operative risk factors for AKI have been recognized in cardiac surgery patients, relatively few data are available regarding the incidence and risk factors for perioperative AKI in other surgical operations. The aim of the present study was to determine the risk factors for perioperative AKI in patients undergoing major abdominal surgery. Methods: This was a prospective, observational study of patients undergoing major abdominal surgery in a tertiary care center. Postoperative AKI was diagnosed according to the Acute Kidney Injury Network criteria within 48 h after surgery. Patients with chronic kidney disease stage IV or V were excluded. Logistic regression analysis was used to evaluate the association between perioperative factors and the risk of developing postoperative AKI. Results: Eleven out of 61 patients developed postoperative AKI. Four intra-operative variables were identified as predictors of AKI: intra-operative blood loss (p = 0.002), transfusion of fresh frozen plasma (p = 0.004) and red blood cells (p = 0.038), as well as high chloride load (p = 0.033, cut-off value > 500 mEq). Multivariate analysis demonstrated an independent association between AKI development and preoperative albuminuria, defined as a urinary Albumin to Creatinine ratio ≥ 30 mg·g−1 (OR = 6.88, 95% CI: 1.43–33.04, p = 0.016) as well as perioperative chloride load > 500 mEq (OR = 6.87, 95% CI: 1.46–32.4, p = 0.015). Conclusion: Preoperative albuminuria, as well as a high intraoperative chloride load, were identified as predictors of postoperative AKI in patients undergoing major abdominal surgery.

Abstract Background and Aims Hemophagocytic lymphohistiocytosis (HLH) is a syndrome characterized by overproduction of proinflammatory cytokines and hemophagocytosis. Acute kidney injury (AKI) is the most common complication of HLH in the kidney, which is a strong predictor of poor prognosis. In this retrospective study, we aimed to find the risk factors of AKI in patients with HLH. Method We screened all adult patients with HLH admitted to West China Hospital of Sichuan University from January 2009 to June 2019. Patients in this study were secondary HLH according to the HLH diagnostic criteria revised by the Histocyte Society in 2004. Patients with HLH were excluded from the study if they had a functioning kidney transplant, received renal replacement therapy (RRT) in the past month, suffered from end-stage renal disease (ESRD), or had the renal malignant tumor. We collected basic information, clinical manifestations, and laboratory data of patients from electronic medical records. Results A total of 600 patients with confirmed diagnosis of secondary HLH are included in our analysis. There are 199(33.2%)HLH-induced AKI patients, among whom 37.2%, 32.7%, and 30.2% are classified as AKI I, II, and III, respectively, according to the 2012 KDIGO (Kidney Disease: Improving Global Outcomes) guideline. Overall hospital mortality is 176(29.3%), and the number of deaths in patients with AKI was much higher than that in patients without AKI (53.3% versus 17.5%, P &lt; 0.001). The risk factors of AKI in patients with HLH were hyperphosphatemia (P&lt;0.001, OR 5.448, 95%CI 2.951-10.059) , vasopressor(P&lt;0.001, OR 3.485, 95%CI 2.114-5.746), heart failure (P=0.044, 0R 2.336, 95%CI 1.022-5.340), gastrointestinal symptoms (P=0.043, OR 1.877, 95%CI 1.021-3.453), increased heart rate (P=0.005, OR 1.017, 95%CI 1.005-1.029), elevated total bilirubin level(P&lt;0.001, OR 1.004, 95%CI 1.002-1.007), and hypoproteinemia (P=0.034, OR 0.939, 95%CI 0.886-0.995). Conclusion The incidence of AKI was higher in patients with HLH, and the risk of death was significantly higher in HLH patients with AKI. A variety of risk factors are related to the occurrence of HLH-induced AKI. Identifying and correcting them early in clinical diagnosis and treatment may reduce the incidence of AKI in patients with HLH and improve the prognosis of them.

Objectives: To describe the incidence of and risk factors for acute kidney injury (AKI) in children with acute respiratory distress syndrome (ARDS) and study the effect of AKI on patient outcomes. Design: A single-center retrospective study. Setting: A tertiary care children’s hospital. Patients: All patients less than 18 years of age who received invasive mechanical ventilation (MV) and developed ARDS between July 2010 and July 2013 were included. Acute kidney injury was defined using p-RIFLE (risk, injury, failure, loss, and end-stage renal disease) criteria. Interventions: None. Measurements and Main Results: One hundred fifteen children met the criteria and were included in the study. Seventy-four children (74/115, 64%) developed AKI. The severity of AKI was risk in 34 (46%) of 74, injury in 19 (26%) of 74, and failure in 21 (28%) of 74. The presence of AKI was associated with lower Pao 2 to Fio 2 (P/F) ratio ( P = .007), need for inotropes ( P = .003), need for diuretics ( P = .004), higher oxygenation index ( P = .03), higher positive end-expiratory pressure (PEEP; P = .01), higher mean airway pressure ( P = .008), and higher Fio 2 requirement ( P = .03). Only PEEP and P/F ratios were significantly associated with AKI in the unadjusted logistic regression model. Patients with AKI had a significantly longer duration of hospital stay, although there was no significant difference in the intensive care unit stay, duration of MV, and mortality. Recovery of AKI occurred in 68% of the patients. A multivariable model including PEEP, P/F ratio, weight, need for inotropes, and need for diuretics had a better receiver operating characteristic (ROC) curve with an AUC of 0.75 compared to the ROC curves for PEEP only and P/F ratio only for the prediction of AKI. Conclusions: Patients with ARDS have high rates of AKI, and its presence is associated with increased morbidity and mortality.

Introduction. Acute kidney injury associated with cardiac surgery is a common and significant postoperative complication. With a frequency of 9 - 39% according to different studies, it is the second most common cause of acute kidney injury in intensive care units, and an independent predictor of mortality. This study aimed to investigate the importance of preoperative hemoglobin and uric acid levels as risk factors for acute kidney injury in the postoperative period in cardiac surgery patients. Material and Methods. The study included a total of 118 patients who were divided into two groups. Each group included 59 patients; the fist group included patients who developed acute kidney injury and required renal replacement therapy, and the second included patients without acute kidney injury. Types of cardiac surgery included coronary, valvular, combined, aortic dissection, and others. All necessary data were collected from patient medical records and the electronic database. Results. A statistically significant difference was found between the groups in preoperative hemoglobin levels (108.0 vs. 143.0 g/l, p = 0.0005); postoperative urea (26.4 vs. 5.8 mmol/l, p = 0.0005) and creatinine (371.0 vs. 95.0 ?mol/l, p = 0.0005), acute phase inflammatory reactants C-reactive protein (119.4 vs. 78.9 mg/l, p = 0.002) and procalcitonin (7.0 vs. 0.2 ng/ml, p = 0.0005), creatine kinase myocardial band isoenzyme (1045.0 vs. 647.0 mg/l, p = 0.014); duration of extracorporeal circulation (103.5 vs. 76.0 min, p = 0.0005) and ascending aortic clamp during cardiac surgery (89.0 vs. 67.0 min, p = 0.0005). The exception was the preoperative uric acid level, where there was no statistically significant difference (382.0 vs. 364.0 ?mol/l, p = 0.068). There was a statistically significant correlation between the use of inotropic agents and acute kidney injury development. Conclusion. There is a correlation between the preoperative low hemoglobin levels and postoperative acute kidney injury. There is no statistically significant correlation between the preoperative levels of uric acid and postoperative acute kidney injury.

Background: Acute Kidney Injury is a common medical problem affecting approximately 5% of all hospitalized and 30% of critically ill patients. The incidence in obstetric patients ranges from 1 in 2000 to 1 in 25000 pregnancies. In India till date, the impact of AKI on fetomaternal outcome and pertaining therapeutic interventions is only sparsely studied.Methods: It is a retrospective cross-sectional study. All obstetric patients with AKI on dialysis, admitted to Shree Krishna Hospital, a tertiary care hospital in Karamsad village in Gujarat from January 2013 to August 2015. Multivariate statistical analysis of clinical and laboratory parameters was performed using SPSS program to obtain the results.Results: The incidence of dialysis was 1.6%. HELLP syndrome and pre-eclampsia (80%) was found to be the most common etiology of AKI followed by Congestive cardiac failure (34.5%), hemorrhage and sepsis in 30% resp. All patients were admitted to ICU care. No significant difference was found between SAP II and SOFA monitoring system. Mechanical ventilation was done to support 53.3% and inotropic support was needed by 56.7% patients. According to the RIFLE criteria, majority of the patients fall under risk category followed by injury. 18% of the patients developed End Stage Renal Disease.Conclusions: In view of the multifaceted etiologies and complexity of management of AKI, a multi-disciplinary approach involving nephrologist, intensivists, obstetricians and neonatologists is extremely important.
