IntroductionAcute kidney injury (AKI) is one of the most common organ dysfunction in sepsis, and increases the risk of unfavourable outcomes. Renal replacement therapy (RRT) is the predominant treatment for sepsis-associated AKI (SAKI). However, to date, no prospective randomised study has adequately addressed whether initiating RRT earlier will attenuate renal injury and improve the outcome of sepsis. The objective of the trial is to compare the early strategy with delayed strategy on the outcomes in patients with SAKI in the intensive care unit (ICU).Methods and analysisThis is a large-scale, multicentre, randomised controlled trial about SAKI. In total, 460 patients with sepsis and evidence of AKI stage 2 of Kidney Disease Improving Global Outcomes (KDIGO) will be recruited and equally randomised into the early group and the delay group in a ratio of 1:1. In the early group, continuous RRT (CRRT) will be started immediately after randomisation. In the delay group, CRRT will initiated if at least one of the following criteria was met: stage 3 of KDIGO, severe hyperkalaemia, pulmonary oedema, blood urea nitrogen level higher than 112 mg/dL after randomisation. The primary outcome is overall survival in a 90-day follow-up period (90-day all-cause mortality). Other end points include 28-day, 60-day and 1-year mortality, recovery rate of renal function by day 28 and day 90, ICU and hospital length of stay, the numbers of CRRT-free days, mechanical ventilation-free days and vasopressor-free days, the rate of complications potentially related to CRRT, CRRT-related cost, and concentrations of inflammatory mediators in serum.Ethics and disseminationThe trial has been approved by the Clinical Research and Application Institutional Review Board of the Second Affiliated Hospital of Guangzhou Medical University (2017–31-ks-01). Participants will be screened and enrolled from patients in the ICU with SAKI by clinicians, with no public advertisement for recruitment. Results will be disseminated in research journals and through conference presentations.Trial registrationNCT03175328.

Introduction Multicenter studies involving patients with acute kidney injury (AKI) associated with the disease caused by the new coronavirus (COVID-19) and treated with renal replacement therapy (RRT) in developing countries are scarce. The objectives of this study were to evaluate the demographic profile, clinical picture, risk factors for mortality, and outcomes of critically ill patients with AKI requiring dialysis (AKI-RRT) and with COVID-19 in the megalopolis of São Paulo, Brazil. Methods This multicenter, retrospective, observational study was conducted in the intensive care units of 13 public and private hospitals in the metropolitan region of the municipality of São Paulo. Patients hospitalized in an intensive care unit, aged ≥ 18 years, and treated with RRT due to COVID-19-associated AKI were included. Results The study group consisted of 375 patients (age 64.1 years, 68.8% male). Most (62.1%) had two or more comorbidities: 68.8%, arterial hypertension; 45.3%, diabetes; 36.3%, anemia; 30.9%, obesity; 18.7%, chronic kidney disease; 15.7%, coronary artery disease; 10.4%, heart failure; and 8.5%, chronic obstructive pulmonary disease. Death occurred in 72.5% of the study population (272 patients). Among the 103 survivors, 22.3% (23 patients) were discharged on RRT. In a multiple regression analysis, the independent factors associated with death were the number of organ dysfunctions at admission and RRT efficiency. Conclusion AKI-RRT associated with COVID-19 occurred in patients with an elevated burden of comorbidities and was associated with high mortality (72.5%). The number of organ dysfunctions during hospitalization and RRT efficiency were independent factors associated with mortality. A meaningful portion of survivors was discharged while dependent on RRT (22.3%).

IntroductionInflammation, dehydration, hypotension and bleeding may all contribute to the development of acute kidney injury (AKI). Accelerated surgery after a hip fracture can decrease the exposure time to such contributors and may reduce the risk of AKI.Methods and analysisHip fracture Accelerated surgical TreaTment And Care tracK (HIP ATTACK) is a multicentre, international, parallel-group randomised controlled trial (RCT). Patients who suffer a hip fracture are randomly allocated to either accelerated medical assessment and surgical repair with a goal of surgery within 6 hours of diagnosis or standard care where a repair typically occurs 24 to 48 hours after diagnosis. The primary outcome of this substudy is the development of AKI within 7 days of randomisation. We anticipate at least 1998 patients will participate in this substudy.Ethics and disseminationWe obtained ethics approval for additional serum creatinine recordings in consecutive patients enrolled at 70 participating centres. All patients provide consent before randomisation. We anticipate reporting substudy results by 2021.Trial registration numberNCT02027896; Pre-results.

Syndrome Type

Acute kidney injury is a serious condition, occurring in up to two-thirds of intensive care unit patients, and 8.8-55% of patients with acute cardiac conditions. Renal replacement therapy is used in about 1.5-15% of intensive care unit patients. The term cardiorenal syndrome refers to combined heart and kidney failure; three types of acute cardiorenal syndrome have been described: acute cardiorenal syndrome or cardiorenal syndrome type 1, acute renocardiac syndrome or cardiorenal syndrome type 3, and acute cardiorenal syndrome type 5 (cardiac and renal injury secondary to a third entity such as sepsis). Acute kidney injury replaced the previously used term 'acute renal failure' and comprises the entire spectrum of the disease, from small changes in function to the requirement of renal replacement therapy. Not only failure, but also minor and less severe decreases, in kidney function are of clinical significance both in the short and long-term. The most recent definition for acute kidney injury is proposed by the Kidney Disease: Improving Global Outcomes clinical practice guidelines workgroup. This definition is a modification of the RIFLE and AKIN definitions and staging criteria, and it stages patients according to changes in the urine output and serum creatinine (see Tables 68.1 and 68.2). Acute kidney injury is a heterogeneous syndrome with different and multiple aetiologies, often with several insults occurring in the same individual. The underlying processes include nephrotoxicity, and neurohormonal, haemodynamic, autoimmune, and inflammatory abnormalities. The most frequent cause for acute kidney injury in intensive cardiac care patients are low cardiac output with an impaired kidney perfusion (cardiogenic shock) and/or a marked increase in venous pressure (acute decompensated heart failure). Predictors for acute kidney injury in these patients include: baseline renal dysfunction, diabetes, anaemia, and hypertension, as well as the administration of high doses of diuretics. In the intensive cardiac care unit, attention must be paid to the prevention of acute kidney injury: monitoring of high-risk patients, prompt resuscitation, maintenance of an adequate mean arterial pressure, cardiac output, and intravascular volume (avoidance of both fluid overload and hypovolaemia), as well as the avoidance or protection against nephrotoxic agents. The treatment of acute kidney injury focuses on the treatment of the underlying aetiology, supportive care, and avoiding further injury from nephrotoxic agents. More specific therapies have not yet demonstrated efficacy. Renal replacement therapy is indicated in life-threatening changes in fluid, electrolyte, and acid-base balance, but there are also arguments for more early initiation.
