Abstract BackgroundThe inconsistencies in classifying AKI according to the KDIGO (Kidney Disease: Improving Global Outcomes) urine output (UO) criteria have prevented an accurate assessment of the role this easily available biomarker can play in the early identification of AKI. Study goal: To assess and compare the performance of the two KDIGO criteria (SCr and UO) for early identification of AKI in the intensive care unit (ICU) by comparing the standard SCr criteria to real-time, consecutive, electronic urine output measurements. Methods95 catheterized patients in the GICU of Hadassah Medical Center, Israel were connected to The RenalSense™ Clarity RMS™ sensor kit to monitor UO electronically (UOelec). UOelec and SCr were recorded between 24-48 hours and up to one week, respectively, after ICU admission. ResultsReal-time consecutive UO measurements identified significantly more AKI patients than SCr in the patient population, 57.9% (N=55) versus 26.4% (N=25), respectively (P<0.0001). In 20 patients that had AKI according to both criteria, time to AKI identification was significantly earlier by the UOelec criteria as compared to the SCr criteria (P<0.0001). Among this population, the median (IQR) identification time of AKI UOelec was 12.75 (8.75, 26.25) hours from ICU admission and 39.06 (25.8, 108.64) hours for AKI SCr. ConclusionApplication of KDIGO criteria for AKI using continuous electronic monitoring of UO identifies more AKI patients, and identifies them earlier, than using the SCr criteria alone. This application can enable the clinician to set protocol goals for earlier intervention of the treatment of AKI.

Abstract Background KDIGO (Kidney Disease: Improving Global Outcomes) provides two sets of criteria to identify and classify acute kidney injury (AKI): serum creatinine (SCr) and urine output (UO). Inconsistencies in the application of KDIGO UO criteria, as well as collecting and classifying UO data, have prevented an accurate assessment of the role this easily available biomarker can play in the early identification of AKI. Study goal To assess and compare the performance of the two KDIGO criteria (SCr and UO) for identification of AKI in the intensive care unit (ICU) by comparing the standard SCr criteria to consistent, real-time, consecutive, electronic urine output measurements. Methods Ninety five catheterized patients in the General ICU (GICU) of Hadassah Medical Center, Israel, were connected to the RenalSense™ Clarity RMS™ device to automatically monitor UO electronically (UOelec). UOelec and SCr were recorded for 24–48 h and up to 1 week, respectively, after ICU admission. Results Real-time consecutive UO measurements identified significantly more AKI patients than SCr in the patient population, 57.9% (N = 55) versus 26.4% (N = 25), respectively (P < 0.0001). In 20 patients that had AKI according to both criteria, time to AKI identification was significantly earlier using the UOelec criteria as compared to the SCr criteria (P < 0.0001). Among this population, the median (interquartile range (IQR)) identification time of AKI UOelec was 12.75 (8.75, 26.25) hours from ICU admission versus 39.06 (25.8, 108.64) hours for AKI SCr. Conclusion Application of KDIGO criteria for AKI using continuous electronic monitoring of UO identifies more AKI patients, and identifies them earlier, than using the SCr criteria alone. This can enable the clinician to set protocol goals for earlier intervention for the prevention or treatment of AKI.

Background Galectin-1 (Gal-1), a member of the β-galactoside binding protein family, is associated with inflammation and chronic kidney disease. However, the effect of Gal-1 on mortality and acute kidney injury (AKI) in critically-ill patients remain unclear. Methods From May 2018 to March 2020, 350 patients admitted to the medical intensive care unit (ICU) of Taipei Veterans General Hospital, a tertiary medical center, were enrolled in this study. Forty-one patients receiving long-term renal replacement therapy were excluded. Serum Gal-1 levels were determined within 24 h of ICU admission. The patients were divided into tertiles according to their serum Gal-1 levels (low, serum Gal-1 < 39 ng/ml; median, 39–70 ng/ml; high, ≥71 ng/ml). All patients were followed for 90 days or until death. Results Mortality in the ICU and at 90 days was greater among patients with elevated serum Gal-1 levels. In analyses adjusted for the body mass index, malignancy, sepsis, Sequential Organ Failure Assessment (SOFA) score, and serum lactate level, the serum Gal-1 level remained an independent predictor of 90-day mortality [median vs. low: adjusted hazard ratio (aHR) 2.11, 95% confidence interval (CI) 1.24–3.60, p = 0.006; high vs. low: aHR 3.21, 95% CI 1.90–5.42, p < 0.001]. Higher serum Gal-1 levels were also associated with a higher incidence of AKI within 48 h after ICU admission, independent of the SOFA score and renal function (median vs. low: aHR 2.77, 95% CI 1.21–6.34, p = 0.016; high vs. low: aHR 2.88, 95% CI 1.20–6.88, p = 0.017). The results were consistent among different subgroups with high and low Gal-1 levels. Conclusion Serum Gal-1 elevation at the time of ICU admission were associated with an increased risk of mortality at 90 days, and an increased incidence of AKI within 48 h after ICU admission.

BackgroundAKI has been reported in patients with COVID-19 pneumonia and it is associated with higher mortality. The aim of our study is to describe characteristics, outcomes, and 60-day hospital mortality of patients with COVID-19 pneumonia and AKI in the intensive care unit (ICU).MethodsWe conducted a retrospective study in which all adult patients with confirmed COVID-19 who were admitted to ICUs of Montefiore Medical Center and developing AKI were included. The study period ranged from March 10 to April 11, 2020. The 60-day follow-up data through June 11, 2020 were obtained.ResultsOf 300 adults admitted to the ICUs with COVID-19 pneumonia, 224 patients (75%) presented with AKI or developed AKI subsequent to admission. A total of 218 (97%) patients required invasive mechanical ventilation for moderate to severe acute respiratory distress syndrome (ARDS). A total of 113 (50%) patients had AKI on day 1 of ICU admission. The peak AKI stages observed were stage 1 in 49 (22%), stage 2 in 35 (16%), and stage 3 in 140 (63%) patients, respectively. Among patients with AKI, 114 patients (51%) required RRT. The mortality rate of patients requiring RRT was 70%. Of the 34 patients who were survivors, 25 (74%) were able to be weaned off RRT completely before hospital discharge. Nonsurvivors were older and had significantly higher admission and peak creatinine levels, admission hemoglobin, and peak phosphate levels compared with survivors. The 60-day hospital mortality was 67%.ConclusionsCOVID-19 requiring ICU admission is associated with high incidence of severe AKI, necessitating RRT in approximately half of such patients. The majority of patients with COVID-19 and AKI in ICU developed moderate to severe ARDS, requiring invasive mechanical ventilation. Timing or severity of AKI did not affect outcomes. The 60-day hospital mortality is high (67%). Patients with AKI requiring RRT have high mortality, but survivors have good rates of RRT recovery.PodcastThis article contains a podcast at https://www.asn-online.org/media/podcast/K360/2020_12_31_KID0004282020.mp3

AbstractAcute kidney injury (AKI) is defined by changes in serum creatinine and urine output (UO). Significant limitations exist regarding accurate ascertainment of urine output even within the intensive care unit. We sought to evaluate an automated urine output collections system and compare it to nursing measurements. We prospectively collected urine output using an electronic urine monitoring system and compared it to charted hourly UO in 44 patients after cardiac surgery at a single university hospital ICU. We calculated UO and oliguria rates and compared them to data from the sensor and from nursing charting. A total of 187 hourly UO measurements were obtained and on average, UO was reported 47 min late, with a median of 18 min, and a maximum of almost 6 h. Patients had a mean hourly UO of 76.3 ml over the observation period. Compared to manual measurements by study personnel, nurses significantly overestimated hourly UO by 19.9 ml (95% CI: 10.3; 29.5; p =  < 0.001). By contrast, the mean difference between the UO measured with the sensor and by study personnel was 2.29 ml (95% CI: − 6.7; 11.3), p = 0.61. Electronic UO monitoring is significantly more accurate than nurse-performed manual measurements in actual intensive care patients. Furthermore, timely ascertainment of UO is difficult to achieve with manual technique, resulting in important delays in detecting oliguria perhaps leading to missed cases of AKI.

Background: Approximately 7% of all hospitalized patients and 20% of acutely ill patients develop signs of AKI. AKI incidence is very high worldwide among intensive care unit patients. Previously long known term, acute renal failure (ARF) is largely replaced by acute kidney injury (AKI), reflecting the recognition that smaller decrements in kidney function that do not result in overt organ failure are of substantial clinical relevance and are associated with increased morbidity and mortality. Objectives: We designed this study to diagnose even mild renal dysfunction earlier than usual time frame with the combined effect of both serum creatinine and urine output criteria, when compared with serum creatinine criterion alone. To establish this objective we used RIFLE serum creatinine and urine output (UO) criteria combined (Scr+UO) and compared with RIFLE serum creatinine (Scr) alone to diagnose AKI early (in days). Design: Prospective observational cohort study. Duration of the study was one year (01 year), from January 2014 to December 2014 Method: All adult patients admitted into department of critical care medicine, BIRDEM General Hospital, DHAKA who received treatment for 48 hours and fulfilled the inclusion and exclusion criteria was included in the study. Representative serum creatinine value was obtained either from the day of admission in hospital, day of admission into or transfer to ICU or any document within last six months. The lesser of pre-ICU admission serum creatinine (SCr) and ICU admission SCr would serve as baseline renal function. Weight in kilogram, representative serum urea/BUN, co-morbidities and reason for ICU admission were incorporated in it. Patient’s daily data entry of renal replacement therapy, daily creatinine value, urinary output over 6 hours, 12 hours, and 24 hours, episode of anuria over 12 hours, if present were documented. Data collected on renal replacement therapy at the time of discharge, if any and outcome in terms of loss and ESRD status were collected. APACHE II data and SAPS II data were calculated and analyzed. Result: Total 236 adult patients were enrolled in the study to assess their renal function status using RIFLE (Risk, Injury, Failure, Loss, End Stage Renal Disease). Serum creatinine was estimated daily for seven days. Those patients who fulfilled the creatinine criteria for RIFLE were categorized into RIFLE serum creatinine (Scr) group. Those patients who met both the criteria for urine output and serum creatinine according to RIFLE was designated as RIFLE serum creatinine and urine output criteria Combined (Scr+ UO) group. In our study, mean of number of days needed for diagnosis of AKI using RIFLE creatinine (Scr) was 3.25 (±1.24) and using RIFLE combined (Scr+uo) criteria was 2.84(±1.03). Conclusion: The present study concludes that RIFLE serum creatinine criterion (Scr) alone delays the diagnosis of AKI in comparison to RIFLE serum creatinine and urine output criteria combined (Scr+UO). AKI should be graded using both the criteria of RIFLE serum creatinine and urine output criteria combined (Scr+UO). Urine output should not be underestimated in AKI diagnosis in ICU patients.

This study aimed to determine the relationships among hyperglycemia (HG), the presence of type 2 diabetes (T2D), and the outcomes of COVID-19. Demographic data, blood glucose levels (BG) measured on admission, and hospital outcomes of COVID-19 patients hospitalized at Boston University Medical Center from 1 March to 4 August 2020 were extracted from the hospital database. HG was defined as BG > 200 mg/dL. Patients with type 1 diabetes or BG < 70 mg/dL were excluded. A total of 458 patients with T2D and 976 patients without T2D were included in the study. The mean ± SD age was 56 ± 17 years and 642 (45%) were female. HG occurred in 193 (42%) and 42 (4%) of patients with and without T2D, respectively. Overall, the in-hospital mortality rate was 9%. Among patients without T2D, HG was statistically significantly associated with mortality, ICU admission, intubation, acute kidney injury, and severe sepsis/septic shock, after adjusting for potential confounders (p < 0.05). However, only ICU admission and acute kidney injury were associated with HG among patients with T2D (p < 0.05). Among the 235 patients with HG, the presence of T2D was associated with decreased odds of mortality, ICU admission, intubation, and severe sepsis/septic shock, after adjusting for potential confounders, including BG (p < 0.05). In conclusion, HG in the subset of patients without T2D could be a strong indicator of high inflammatory burden, leading to a higher risk of severe COVID-19.
