Background: Studies evaluating the risk of developing acute kidney injury (AKI) with different dosing strategies of polymyxin B are limited. Objectives: To compare the incidence of AKI in patients treated with intermittent versus continuous polymyxin B therapy. Secondary objectives included time to onset of AKI, hospital length of stay (LOS), and all-cause hospital mortality. Variables associated with an increased risk of AKI were evaluated. Methods: A retrospective record review was conducted at a single center in Puerto Rico. Adult patients (≥18 years old) treated with polymyxin B (first course) for at least 48 hours from 2013-2015 were evaluated. Patients with a creatinine clearance <10 mL/min and/or on renal replacement were excluded. Results: A total of 69 patients were included: 42 in the continuous infusion and 27 in the intermittent dosing group. Incidence of AKI was not significantly different between the groups (intermittent 41% vs continuous 31%, P = 0.4). No difference was found in the onset of nephrotoxicity, hospital LOS, or all-cause hospital mortality. Variables associated with increased risk of AKI were baseline serum creatinine, age, and intensive care unit admission. Patients with a body mass index (BMI) >25 kg/m2 on polymyxin B via continuous infusion had a significantly higher cumulative incidence of AKI ( P = 0.016). Conclusion and Relevance: No difference in the risk of polymyxin B nephrotoxicity was found between intermittent and continuous infusion administration. Administration of polymyxin B via a continuous infusion may result in a higher risk of AKI in patients with a BMI >25 kg/m2.

Background and Purpose: While an association between hyperchloremia and worse outcomes, such as acute kidney injury and increased mortality, has been demonstrated in hemorrhagic stroke, it is unclear whether the same relationship exists after acute ischemic stroke. This study aims to determine the relationship between moderate hyperchloremia (serum chloride ≥115 mmol/L) and acute kidney injury in patients with ischemic stroke. Methods: This is a multicenter, retrospective, propensity-matched cohort study of adults admitted for acute ischemic stroke. The primary objective was to determine the relationship between moderate hyperchloremia and acute kidney injury, as defined by the Acute Kidney Injury Network criteria. Secondary objectives included mortality and hospital length of stay. Results: A total of 407 patients were included in the unmatched cohort (332 nonhyperchloremia and 75 hyperchloremia) and 114 patients (57 in each group) were matched based upon propensity scores. In the matched cohort, hyperchloremia was associated with an increased risk of acute kidney injury (relative risk 1.91 [95% confidence interval 1.01-3.59]) and a longer hospital length of stay (16 vs 12 days; P = .03). Mortality was higher in the hyperchloremia group (19.3% vs 10.5%, P = .19), but this did not reach statistical significance. Conclusions: In this study, hyperchloremia after ischemic stroke was associated with increased rates of acute kidney injury and longer hospital length of stay. Further research is needed to determine which interventions may increase chloride levels in patients with acute ischemic stroke and the association between hyperchloremia and clinical outcomes.

Background: Critically ill patients with COVID-19 are prone to develop severe acute kidney injury (AKI), defined as KDIGO (Kidney Disease Improving Global Outcomes) stages 2 or 3. However, data are limited in these patients. We aimed to report the incidence, risk factors, and prognostic impact of severe AKI in critically ill patients with COVID-19 admitted to the intensive care unit (ICU) for acute respiratory failure. Methods: A retrospective monocenter study including adult patients with laboratory-confirmed severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection admitted to the ICU for acute respiratory failure. The primary outcome was to identify the incidence and risk factors associated with severe AKI (KDIGO stages 2 or 3). Results: Overall, 110 COVID-19 patients were admitted. Among them, 77 (70%) required invasive mechanical ventilation (IMV), 66 (60%) received vasopressor support, and 9 (8.2%) needed extracorporeal membrane oxygenation (ECMO). Severe AKI occurred in 50 patients (45.4%). In multivariable logistic regression analysis, severe AKI was independently associated with age (odds ratio (OR) = 1.08 (95% CI (confidence interval): 1.03–1.14), p = 0.003), IMV (OR = 33.44 (95% CI: 2.20–507.77), p = 0.011), creatinine level on admission (OR = 1.04 (95% CI: 1.008–1.065), p = 0.012), and ECMO (OR = 11.42 (95% CI: 1.95–66.70), p = 0.007). Inflammatory (interleukin-6, C-reactive protein, and ferritin) or thrombotic (D-dimer and fibrinogen) markers were not associated with severe AKI after adjustment for potential confounders. Severe AKI was independently associated with hospital mortality (OR = 29.73 (95% CI: 4.10–215.77), p = 0.001) and longer hospital length of stay (subhazard ratio = 0.26 (95% CI: 0.14–0.51), p < 0.001). At the time of hospital discharge, 74.1% of patients with severe AKI who were discharged alive from the hospital recovered normal or baseline renal function. Conclusion: Severe AKI was common in critically ill patients with COVID-19 and was not associated with inflammatory or thrombotic markers. Severe AKI was an independent risk factor of hospital mortality and hospital length of stay, and it should be rapidly recognized during SARS-CoV-2 infection.

AbstractBackgroundThis study aimed to observe the difference in risk of polymyxin B-induced acute kidney injury with or without dose adjustment by patients’ renal function.MethodA retrospective cohort analysis was carried out for patients who were treated with polymyxin B in Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from November 2018 to October 2019. Patients were divided into adjusted dosage group and non-adjusted dosage group depended on dosage adjustment with renal function or not. A comparison of acute kidney injury incidence between the two groups was the primary outcome of this research. The secondary outcome included hospital length of stay, microbiological cure, clinical cure, and 30-day mortality.ResultA total of 115 patients met the requirements of this study and were included in the analysis. Thirty-five patients were included in the non-adjusted dosage group and 80 in the adjusted dosage group. Patients from both groups had similar characteristics. The total daily dose of polymyxin B in the Non-adjusted dosage group was significantly higher than the adjusted dosage group (1.98 mg/kg/d vs 1.59 mg/kg/d, P=0.001). For the primary outcome of this research, no significant difference in the incidence of acute kidney injury was observed in these two groups (47.5% vs 37.14%, P=0.304), as well as the secondary outcomes, including hospital length of stay, microbiological cure, clinical cure, 30-day mortality.ConclusionDosing adjustment renally could not lower the risk of polymyxin B-induced acute kidney injury significantly. A non-adjusted dosing strategy of polymyxin B is recommended when patients suffered from various levels of renal impairment.

Abstract Background In neutropenic patients, a fever may be the only indication of a severe underlying infection. According to the National Comprehensive Cancer Network (NCCN) guidelines, for high-risk patients, monotherapy with an anti-pseudomonal β-lactam agent should be initiated. NCCN states emerging data may support extended or continuous infusions of β-lactam therapies; however, preference is not given for cefepime or piperacillin/tazobactam. The objective of this study was to compare the outcomes of extended infusions of piperacillin/tazobactam vs. cefepime for the empiric treatment of neutropenic fever. Methods This retrospective, single-center cohort study included patients ≥18 years with an absolute neutrophil count (ANC) less than 500 cells/mm3, single oral temperature measurement ≥38.3°C or ≥38°C sustained over 1 hour period and admitted to a bone marrow transplant unit. Patients received extended infusion piperacillin/tazobactam or cefepime as initial antibiotic therapy for at least 48 hours between January 1, 2015 and September 1, 2018. The primary outcome was time to defervescence in hours. Secondary outcomes included time to defervescence and no acetaminophen use within 8 hours, defervescence by 72 hours, hospital length of stay, clinical failure, in-hospital mortality, and acute kidney injury. Results 73 patients were included in this study (36 received piperacillin/tazobactam and 37 received cefepime). The primary outcome of median time to defervescence was 31.8 hours in the piperacillin/tazobactam group and 25 hours in the cefepime group (P = 0.26). Secondary outcomes in the piperacillin/tazobactam group compared with cefepime, respectively included median time to defervescence and no acetaminophen use: 43 vs. 35 hours (P = 0.16), defervescence by 72 hours: 66.7% vs. 91.9% (P = 0.01), median hospital length of stay 28 vs. 22 days (P = 0.04), clinical failure 22.2% vs. 24.3% (P = 0.83), in-hospital mortality 8.3% vs. 2.8% (P = 0.36), rate of acute kidney injury: 50% vs. 24.3% (P = 0.02). Conclusion These findings suggest there is no difference in time to defervescence between extended infusions of piperacillin/tazobactam compared with extended infusions of cefepime for the empiric treatment of neutropenic fever.

Background: Acute kidney injury (AKI) requiring kidney replacement therapy (KRT) is associated with high mortality and utilization. We evaluated the use of an AKI-Standardized Clinical Assessment and Management Plan (SCAMP) on patient outcomes including mortality, hospital and ICU length of stay. Methods: We conducted a 12-month controlled study in the ICUs of a large academic tertiary medical center. We alternated use of the AKI-SCAMP with use of a "sham" control form in 4-6-week blocks. The primary outcome was risk of inpatient mortality. Pre-specified secondary outcomes included 30-day mortality, 60-day mortality and hospital and ICU length of stay. Generalized estimating equations were used to estimate the impact of the AKI-SCAMP on mortality and length of stay. Results: There were 122 patients in the AKI-SCAMP group and 102 patients in the control group. There was no significant difference in inpatient mortality associated with AKI-SCAMP use (41% vs 47% control). AKI-SCAMP use was associated with significantly reduced ICU length of stay (mean 8 (95% CI 8-9) vs 12 (95% CI 10-13) days; p = <0.0001) and hospital length of stay (mean 25 (95% CI 22-29) vs 30 (95% CI 27-34) days; p = 0.02). Patients in the AKI-SCAMP group less likely to receive KRT in the context of physician-perceived treatment futility than those in the control group (2% vs 7%, p=0.003). Conclusions: Use of the AKI-SCAMP tool for AKI-KRT was not significantly associated with inpatient mortality but was associated with reduced ICU and hospital length of stay and use of KRT in cases of physician-perceived treatment futility.

Abstract Background Several studies have identified that the addition of vancomycin (VAN) to piperacillin–tazobactam (PT) is associated with a higher incidence of nephrotoxicity when compared with other antibiotic regimens. Beginning in June 2017, our lung transplant antibiotic prophylaxis regimen was modified from PT monotherapy to VAN and PT. Methods All adult lung transplant patients between January 1, 2015 and November 10, 2018 were included. Patients were excluded if acute kidney injury (AKI) was present prior to transplant. Rates of AKI within 7 days of transplant were compared between those who received prophylaxis with PT and VAN vs. those receiving alternative regimens (AR). Patients receiving less than 1 dose of vancomycin or less than 3 doses PT (less than 24hours) were deemed to be in the alternative regimen group. AKI was defined as either an increase in serum creatinine (SCr) by ≥0.3 mg/dL within 48 hours or increase in SCr to ≥1.5 times baseline (within 7 days post-transplant). Secondary outcomes included duration of initial prophylactic antibiotic regimens, hospital length of stay (LOS), and all-cause inpatient mortality. Results Eighty-six patients were included, 44 (51%) patients received PT/VAN. Baseline characteristics and results shown in Table 1. Of those receiving PT/VAN for prophylaxis, 24 (54%) developed AKI within 7 days of transplant while 15 (36%) of 42 patients receiving AR developed AKI (P = 0.08). Conclusion A larger proportion of patients that received PT/VAN for transplant antibiotic prophylaxis experienced AKI within 7 days. Although the difference did not reach statistical significance, a 19% higher incidence of AKI warrants need for further investigation. Disclosures All authors: No reported disclosures.

Background and objectives: Calcium concentration is strictly regulated at both the cellular and systemic level, and changes in serum calcium levels can alter various physiological functions in various organs. This study aimed to assess the association between changes in calcium levels during hospitalization and mortality. Materials and Methods: We searched our patient database to identify all adult patients admitted to our hospital from January 1st, 2009 to December 31st, 2013. Patients with ≥2 serum calcium measurements during the hospitalization were included. The serum calcium changes during the hospitalization, defined as the absolute difference between the maximum and the minimum calcium levels, were categorized into five groups: 0–0.4, 0.5–0.9, 1.0–1.4, 1.5–1.9, and ≥2.0 mg/dL. Multivariable logistic regression was performed to assess the independent association between calcium changes and in-hospital mortality, using the change in calcium category of 0–0.4 mg/dL as the reference group. Results: Of 9868 patients included in analysis, 540 (5.4%) died during hospitalization. The in-hospital mortality progressively increased with higher calcium changes, from 3.4% in the group of 0–0.4 mg/dL to 14.5% in the group of ≥2.0 mg/dL (p < 0.001). When adjusted for age, sex, race, principal diagnosis, comorbidity, kidney function, acute kidney injury, number of measurements of serum calcium, and hospital length of stay, the serum calcium changes of 1.0–1.4, 1.5–1.9, and ≥2.0 mg/dL were significantly associated with increased in-hospital mortality with odds ratio (OR) of 1.55 (95% confidence interval (CI) 1.15–2.10), 1.90 (95% CI 1.32–2.74), and 3.23 (95% CI 2.39–4.38), respectively. The association remained statistically significant when further adjusted for either the lowest or highest serum calcium. Conclusion: Larger serum calcium changes in hospitalized patients were progressively associated with increased in-hospital mortality.

Minimizing perioperative fluid administration is a key component of enhanced recovery after surgery protocols (ERAS). Acute kidney injury (AKI) is a major cause of morbidity and mortality in hospitalized patients. Our aim was to assess the association of ERAS with the incidence and severity of AKI in patients undergoing elective colorectal surgery. In this single-study retrospective review, patients undergoing colorectal surgery from 2013 to 2017 were included. Primary endpoint was postoperative AKI. Secondary outcomes were hospital length of stay (LOS) and 30-day readmission. Baseline demographics and procedure types were similar between both groups. AKI was higher in the ERAS versus non-ERAS group (23 vs 9%; P = 0.002). Factors associated with increased risk of AKI on univariate regression included presence of preoperative cardiovascular risk factors (hazard ratio (HR) 3.5; 95% CI 1.3–9.7; P < 0.01), more complex colorectal operations (HR 5.1; 95% CI 1.6–16.1; P < 0.01), and management with an ERAS pathway (HR 2.9; 95% CI 1.5–5.8; P < 0.01). On multi-variable analysis, ERAS remained a significant risk factor for developing AKI (HR 3.44; 95% CI 1.5–7.7; P < 0.01). ERAS patients had a shorter hospital LOS (3.9 vs 5.9 days, P < 00.1) compared with non-ERAS patients, with no difference in 30-day readmission rates (11.5 vs 10.7%; P = 0.98). Although the incidence of AKI is higher in patients treated with ERAS protocols, the majority represent minor elevations in baseline serum creatinine and did not affect the reduction in hospital LOS associated with ERAS. Given the potential association of AKI, however, with increased long-term morbidity and mortality, ERAS protocols should be optimized to prevent postoperative AKI.
