Incidence and Risk Factors of Acute Kidney Injury after Kasai Operation for Biliary Atresia: A Retrospective Study

Background: Cloxacillin has been associated with the occurrence of acute kidney injury (AKI). The incidence of this complication in the literature is low (2.5–3.5%) and probably underestimated, since most studies were done by selecting the presence of AKI in discharge codes. Objectives: The primary goal was to define the incidence of AKI in patients with a methicillin-sensitive Staphylococcus aureus infection treated with cloxacillin based antibiotic regimens. The secondary goals were to identify the risk factors associated with this complication and to describe the characteristics of AKI. Patients and methods: We carried out a retrospective study. The inclusion criteria were adult patients hospitalized in a medical department at the Le Mans Hospital between 1 July 2012 and 1 July 2019 with a diagnosis of methicillin-sensitive Staphylococcus aureus infection treated with cloxacillin. Results: One hundred twenty-three patients were included in the study. Forty-two patients (34.2%) developed AKI. In the multivariate analysis, age, the use of diuretics and the presence of endocarditis were independently associated with AKI. Age was associated with an OR of 4.38 (p = 0.002) for patients older than 75, being treated with diuretics was associated with an OR of 2.94 (p = 0.036) for loop diuretics and an OR of 3.05 (p = 0.027) for non-loop diuretics; type of infection was associated with an OR of 3.42 (p = 0.012) for endocarditis. Conclusions: The occurrence of AKI is frequent during cloxacillin based antibiotic regimens for methicillin-sensitive Staphylococcus aureus infections. Being older than 75, being treated with diuretics and the presence of endocarditis were the main risk factors for AKI in our population.

Abstract In patients with renal cell carcinoma (RCC) and cancer-related thrombosis in the inferior vena cava (IVC) or right atrium (AT), it is still unknown whether nephrectomy, anesthesia, and surgical trauma can cause postoperative acute kidney injury (AKI) and what are the risk factors for AKI. To examine the incidence and risk factors of postoperative AKI in patients who underwent unilateral radical nephrectomy and cardiopulmonary bypass (CPB)-assisted thrombectomy in the IVC and/or atrial AT due to RCC complicated with cancer-associated thrombosis. This retrospective study included patients who underwent unilateral radical nephrectomy and CPB-assisted thrombectomy in the inferior vena cava and/or atrial pulmonary artery due to RCC, under general anesthesia, from December 2011 to June 2015, at Peking University First Hospital. Among 31 patients, 15 (48.4%) had postoperative AKI. Compared with the non-AKI group (n = 16), patients in the AKI group (n = 15) were older (59.0 ± 8.7 vs. 48.5 ± 12.9 years, P = 0.012) had smaller intraoperative urine volume (1225 ± 639 vs. 1685 ± 597 mL, P = 0.048). There were no differences in preoperative creatinine clearance. Age (OR = 1.10, 95%CI: 1.02–1.20, P = 0.020) was independently associated with AKI occurrence. The patients undergoing unilateral radical nephrectomy and CPB-assisted IVC thrombectomy have a high rate of AKI. Older ones are at a higher risk of postoperative AKI.
