OBJECTIVES: In 2020, cefiderocol became the first Food and Drug Administration-approved medication with continuous renal replacement therapy (CRRT) dosing recommendations based on effluent flow rates ( Q E ). We aimed to evaluate the magnitude and frequency of factors that may influence these recommendations, that is, Q E intrapatient variability and residual renal function. DESIGN: Retrospective observational cohort study. SETTING: ICUs within Hartford Hospital (890-bed, acute-care hospital) in Connecticut from 2017 to 2023...

Meticulous antimicrobial management is essential among critically ill patients with acute kidney injury, particularly if renal replacement therapy is needed. Many factors affect drug removal in patients undergoing continuous renal replacement therapy CRRT. In this study, we aimed to compare current databases that are frequently used to adjust CRRT dosages of antimicrobial drugs with the gold standard. The dosage recommendations from various databases for antimicrobial drugs eliminated by CRRT were investigated...

IMPORTANCE: The outcomes of critically ill adults with obesity on continuous renal replacement therapy (CRRT) are poorly characterized. The impact of CRRT dose on these outcomes is uncertain. OBJECTIVES: This study aimed to determine if obesity conferred a survival advantage for critically ill adults with acute kidney injury (AKI) on CRRT. Secondarily, we evaluated whether the dose of CRRT predicted mortality in this population. DESIGN SETTING AND PARTICIPANTS: A retrospective, observational cohort study performed at an academic medical center in Minnesota...

Acute renal failure (AKI) is a high-prevalence complication in patients with cancer. The risk of AKI after cancer diagnosis is 18% in the first year, 27% in the fifth year, and 40% of critically ill patients with cancer require renal replacement therapy. The causes of AKI may be pre-renal due to hemodynamic problems, related to the cancer, metabolic complications, and drug or surgical treatment. One must preventively protect renal function by hydration, use of non-nephrotoxic drugs, correction of anemia, prevention of contrast agent-induced AKI (CI-AKI), and adjustment of cancer therapy in patients with CKD...

Nirmatrelvir/ritonavir is a highly efficacious agent against severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection. Although dose adjustment is recommended in patients with renal impairment according to the package insert of Paxlovid (Pfizer), there is no dose recommendation for patients with severe renal impairment who need continuous renal replacement therapy (CRRT). To characterize the features of nirmatrelvir/ritonavir in critically ill Chinese patients undergoing CRRT, therapeutic drug monitoring of nirmatrelvir/ritonavir was applied by a high-performance liquid chromatography-tandem mass spectrometry assay in eight patients...

BACKGROUND: Ceftazidime and clindamycin are commonly prescribed to critically ill patients who require extracorporeal life support such as ECMO and CRRT. The effect of ECMO and CRRT on the disposition of ceftazidime and clindamycin is currently unknown. METHODS: Ceftazidime and clindamycin extraction were studied with ex vivo ECMO and CRRT circuits primed with human blood. The percent recovery of these drugs over time was calculated to determine the degree of interaction between these drugs and circuit components...

Appropriate antibiotic treatment for critically ill patients with serious Gram-negative infections in the intensive care unit is crucial to minimize morbidity and mortality. Several new antibiotics have shown in vitro activity against carbapenem-resistant Enterobacterales (CRE) and difficult-to-treat resistant Pseudomonas aeruginosa. Cefiderocol is the first approved siderophore beta-lactam antibiotic with potent activity against multidrug-resistant, carbapenem-resistant, difficult-to-treat or extensively drug-resistant Gram-negative pathogens, which have limited treatment options...

BACKGROUND: The Surviving Sepsis Campaign suggested preferential resuscitation with balanced crystalloids, such as Lactated Ringer's (LR), although the level of recommendation was weak, and the quality of evidence was low. Past studies reported an association of unbalanced solutions, such as normal saline (NS), with increased AKI risks, metabolic acidosis, and prolonged ICU stay, although some of the findings are conflicting. We have compared the outcomes with the preferential use of normal saline vs...

Continuous renal replacement techniques (CRRT) can induce complications and monitoring is crucial to ensure patient safety. We designed a prospective multicenter observational and descriptive study using the DIALYREG registry, an online database located on a REDCap web-based platform that allows real-time data analysis. Our main objective was to identify CRRT-related complications in our intensive care units (ICUs) and implement security measures accordingly. From January 2019 to December 2020, we included 323 patients with admission diagnoses of medical illness (54%), sepsis (24%), postoperative care (20%), and trauma (2%)...

Objective: The influence of continuous renal replacement therapy (CRRT) on the steady-state plasma concentration of high-dose tigecycline was investigated in septic shock patients to provide references for drug dosing. Methods: In this prospective observational study, 17 septic shock patients presenting with severe infections needing a broad-spectrum antibiotic therapy with high-dose tigecycline (100 mg per 12 h) in the intensive care unit were included and divided into CRRT group ( n = 6) or non-CRRT group ( n = 11)...

OBJECTIVE: The purpose of this study was to analyze the improvement effect of clinical pharmacist intervention on renal function impairment in patients with antimicrobial-induced acute kidney injury (AKI). METHODS: A total of 145 patients with AKI caused by antibiotics admitted to the ICU department were selected as the research subjects. The patients were divided into the control group (n=57) and the intervention group (n=88) according to whether there were ICU specialist clinical pharmacists involved in clinical treatment...

INTRODUCTION: Continuous renal replacement therapies (CRRTs) are frequently used in critically ill patients; however, there are scarce in vitro and in vivo studies showing the extracorporeal elimination of ceftaroline and avibactam. The aim of this study was to assess, through an in vitro model, the extracorporeal elimination of ceftaroline and avibactam by continuous veno-venous hemofiltration (CVVH), continuous veno-venous hemodiafiltration (CVVHDF), and continuous veno-venous hemodialysis (CVVHD), using a polysulfone hemofilter...

Extracorporeal life support (ECLS) devices are lifesaving for critically ill patients with multi-organ dysfunction. Despite this, patients supported with ECLS are at high risk for ECLS-related complications, including nosocomial infections, and mortality rates are high in this patient population. The high mortality rates are suspected to be, in part, a result of significantly altered drug disposition by the ECLS circuit, resulting in suboptimal antimicrobial dosing. Cefepime is commonly used in critically ill patients with serious infections...

STUDY OBJECTIVE: Few studies have been conducted to quantify the exposure target of vancomycin in intensive care unit (ICU) patients undergoing continuous renal replacement therapy (CRRT) and provide optimized dosage regimens. We aimed to determine vancomycin exposure target and dosing recommendations using data from an open database in critically ill patients undergoing CRRT. DESIGN: A retrospective observational cohort study. DATA SOURCE: A large public database...
