ObjectiveTo analyse the incidence, risk factors and impact of acute kidney injury (AKI) on the prognosis of patients with COVID-19.DesignMeta-analysis.Data sourcesPubMed, Embase, CNKI and MedRxiv of Systematic Reviews from 1 January 2020 to 15 May 2020.Study selectionStudies examining the following demographics and outcomes were included: patients’ age; sex; incidence of and risk factors for AKI and their impact on prognosis; COVID-19 disease type and incidence of continuous renal replacement therapy (CRRT) administration during COVID-19 infection.ResultsA total of 79 research articles, including 49 692 patients with COVID-19, met the systemic evaluation criteria. The mortality rate and incidence of AKI in patients with COVID-19 in China were significantly lower than those in patients with COVID-19 outside China. A significantly higher proportion of patients with COVID-19 from North America were aged ≥65 years and also developed AKI. European patients with COVID-19 had significantly higher mortality and a higher CRRT rate than patients from other regions. Further analysis of the risk factors for COVID-19 combined with AKI showed that age ≥60 years and severe COVID-19 were independent risk factors for AKI, with an OR of 3.53, 95% CI (2.92–4.25) and an OR of 6.07, 95% CI (2.53–14.58), respectively. The CRRT rate in patients with severe COVID-19 was significantly higher than in patients with non-severe COVID-19, with an OR of 6.60, 95% CI (2.83–15.39). The risk of death in patients with COVID-19 and AKI was significantly increased, with an OR of 11.05, 95% CI (9.13–13.36).ConclusionAKI was a common and serious complication of COVID-19. Older age and having severe COVID-19 were independent risk factors for AKI. The risk of in-hospital death was significantly increased in patients with COVID-19 complicated by AKI.

Abstract Background After lung transplantation (LT), some patients are at risk of acute kidney injury (AKI), which is associated with worse outcomes and increased mortality. Method Among 161 patients who underwent LT at Severance hospital in Seoul, Korea from October 2012 to September 2017, 148 patients were retrospectively enrolled. Results 59 (39.8%) developed AKI within 1-month after LT. Stage I or II, and stage III AKI were recorded in 26 (17.5%) and 33 (22.2%), respectively. AKI III usually occurred within 7 days after transplantation (early vs. late AKI III, 72.5% vs 21.1%). Pre-operative anemia, units of red blood cells transfused during surgery, colistin intravenous infusion for treating multi drug resistant pathogens were independent risk factors for AKI development. Post-operative bleeding, grade 3 PGD within 72 hrs, and sepsis were more common in the AKI group. Patients with AKI III ([24/33] 72.7%) had significantly higher 1-year mortality than the no-AKI ([18/89] 20.2%), and AKI I or II group ([9/26] 34.6%), log-rank test, P < 0.001). Conclusion AKI was associated with worse post-operative outcome, 3-month, and 1-year mortality after LT. Severity of AKI was usually determined in early post op period after LT, so optimal post-operative management as well as recipients selection should be considered.

AbstractBackgroundAcute kidney injury (AKI) is a recently recognized complication of coronavirus disease-2019 (COVID-19). This study aims to evaluate the incidence, risk factors and case-fatality rate of AKI in patients with documented COVID-19.MethodsWe reviewed the health medical records of 307 consecutive patients hospitalized for symptoms of COVID-19 at the University Hospital of Modena, Italy.ResultsAKI was diagnosed in 69 out of 307 (22.4%) patients. The stages of AKI were stage 1 in 57.9%, stage 2 in 24.6% and stage 3 in 17.3%. Hemodialysis was performed in 7.2% of the subjects. AKI patients had a mean age of 74.7±9.9 years and higher serum levels of the main marker of inflammation and organ involvement (lung, liver, hearth and liver) than non-AKI patients. AKI events were more frequent in subjects with severe lung comprise. Two peaks of AKI events coincided with in-hospital admission and death of the patients. Kidney injury was associate with a higher rate of urinary abnormalities including proteinuria (0.448±0.85 vs 0.18±0.29; P=<0.0001) and hematuria (P=0.032) compared to non-AKI patients. At the end of follow-up, 65.2% of the patients did not recover their renal function after AKI. Risk factors for kidney injury were age, male sex, CKD and non-renal SOFA. Adjusted Cox regression analysis revealed that AKI was independently associated with in-hospital death (hazard ratio [HR]=3.74; CI 95%, 1.34-10.46) compared to non-AKI patients. Groups of patients with AKI stage 2-3 and failure to recover kidney function were associated with the highest risk of in-hospital mortality. Lastly, long-hospitalization was positively associated with a decrease of serum creatinine, likely due to muscle depletion occurred with prolonged bed rest.ConclusionsAKI was a dire consequence of patients with COVID-19. Identification of patients at high-risk for AKI and prevention of kidney injury by avoiding dehydration and nephrotoxic agents is imperative in this vulnerable cohort of patients.

Introduction: Acute kidney injury (AKI) increases morbidity and mortality in several acute illnesses. Here, we examine the incidence, risk factors, and in-hospital outcomes of AKI in patients hospitalized for aneurysmal subarachnoid hemorrhage (aSAH). Methods: The Nationwide Inpatient Sample was queried from 2002 and 2011 for all emergency hospitalizations (age≥18) with a primary diagnosis of aSAH and a secondary diagnosis of AKI. Patients with chronic renal disease, renal transplant, or trauma were excluded from the analysis. The effect of various patient factors on AKI incidence and its impact on length of stay (LOS), in-hospital costs, and in-hospital mortality was examined in bivariate and multivariate analyses. Results: Of 250,437 total hospitalizations for aSAH, the overall incidence of AKI was 4.0% (n=10,450) and increased from 2.1% in 2002 to 5.7% in 2011 (p<0.0001). The strongest multivariate predictors of AKI were 60-74 age group (OR: 1.43, 95% CI: 1.31-1.56), 75+ age group (OR: 1.81, 95% CI: 1.63-2.00), male gender (OR: 1.80, 95% CI: 1.69-1.87), Black race (OR: 1.45, 95% CI: 1.35-1.55), Medicaid insurance (OR: 1.29, 95% CI: 1.19-1.40), congestive heart failure (OR: 2.13, 95% CI: 1.98-2.28), liver disease (OR: 2.42, 95% CI: 2.13-2.75), fluid/electrolyte disorder (OR: 3.10, 95% CI: 2.95-3.27), and HIV (OR: 2.24, 95% CI: 1.66-3.01) (all p<0.0001). Aneurysmal coiling (OR: 0.81, 95% CI: 0.75-0.87) and clipping (OR: 0.75, 95% CI: 0.70-0.80) decreased the likelihood of suffering AKI (all p<0.0001). Cardiac arrest, septic shock, and acute lung injury were in-hospital complications that increased the odds of AKI (all p<0.0001). AKI occurrence in aSAH increased the mean LOS by 7.2 days and mean total costs by $28,813 (all p<0.0001). After adjusting for confounding factors, aSAH related AKI patients had increased likelihood of moderate to severe disability (OR: 2.03, 95% CI: 1.89-2.19, p<0.0001) and in-hospital death (OR: 2.14, 95% CI: 2.03-2.26, p<0.0001). Conclusion: The incidence of AKI in hospitalized aSAH patients has increased over the past decade and is both detrimental to hospital costs and patient prognosis. We identified patient-centered risk factors for AKI, allowing for the close surveillance of patients at the highest risk for AKI.

Abstract Objectives To investigate the incidence, risk factors and outcomes of acute kidney injury (AKI) in elderly patients undergoing abdominal surgery. Methods A retrospective study exploring the incidence of AKI in patients older than 75 years within 48 hours after abdominal surgery was conducted. Patients' preoperative characteristics, intraoperative management including medication and outcomes were evaluated for associations with AKI using a logistic regression model.Results During the 2.5-year period, a total of 409 abdominal surgeries were performed. Both pre- and post-operative SCr measurements were available for 329 (80.4%) cases. 26 patients (7.9%) developed AKI, of whom 25 (7.6%) and 1 (0.3%) reached the AKI stages 1 and 2 respectively. Older age (83.0 vs 80.4 years; p=0.002), preoperative liver function damage represented by AST (47.5 vs 21.0 IU/L; p=0.023), intraoperative combined administration of hydroxyethyl starch(HES) and furosemide (15.38% vs 1.65%; p=0.003) were independent risk factors for the development of postoperative AKI. Furthermore, AKI patients had significantly longer ICU stay (3 vs 0 days; p<0.001) and higher in-hospital mortality (23.08% vs 2.31%; p<0.001)Conclusion Intraoperative combined administration of HES and furosemide is an independent factor which can be controlled by anesthesiologists and surgeons for AKI. This provides important recommendations for reducing the incidence of postoperative AKI.

Abstract Background Research regarding COVID-19 and acute kidney injury (AKI) in older adults is scarce. We evaluated risk factors and outcomes of AKI in hospitalized older adults with and without COVID-19. Methods Observational study of patients admitted to two geriatric clinics in Stockholm from March 1st to June 15th, 2020. The difference in incidence, risk factors and adverse outcomes for AKI between patients with or without COVID-19 were examined. Odds ratios (OR) for the risk of AKI and in-hospital death were obtained from logistic regression. Results Three hundred-sixteen older patients were hospitalized for COVID-19 and 876 patients for non-COVID-19 diagnoses. AKI occurred in 92 (29%) patients with COVID-19 vs. 159 (18%) without COVID-19. The odds for developing AKI were higher in patients with COVID-19 (adjusted OR, 1.70; 95% confidence interval [CI] 1.04–2.76), low baseline kidney function as depicted by estimated glomerular filtration rate (eGFR) [4.19 (2.48–7.05), for eGFR 30 to  < 60 mL/min, and 20.3 (9.95–41.3) for eGFR < 30 mL/min], and higher C reactive protein (CRP) (OR 1.81 (1.11–2.95) in patients with initial CRP > 10 mg/L). Compared to patients without COVID-19 and without AKI, the risk of in-hospital death was highest in patients with COVID-19 and AKI [OR 80.3, 95% CI (27.3–235.6)], followed by COVID-19 without AKI [16.3 (6.28–42.4)], and by patients without COVID-19 and with AKI [10.2 (3.66–28.2)]. Conclusions Geriatric patients hospitalized with COVID-19 had a higher incidence of AKI compared to patients hospitalized for other diagnoses. COVID-19 and reduced baseline kidney function were risk factors for developing AKI. AKI and COVID-19 were associated with in-hospital death.

Abstract Background Acute kidney injury (AKI) is a common complication in burn patients admitted to the intensive care unit (ICU) associated with increased morbidity and mortality. Our primary aim was to review incidence, risk factors, and outcomes of AKI in burn patients admitted to the ICU. Secondary aims were to review the use of renal replacement therapy (RRT) and impact on health care costs. Methods We conducted a systematic search in PubMed, UpToDate, and NICE through 3 December 2018. All reviews in Cochrane Database of Systematic Reviews except protocols were added to the PubMed search. We searched for studies on AKI according to Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease (RIFLE); Acute Kidney Injury Network (AKIN); and/or Kidney Disease: Improving Global Outcomes (KDIGO) criteria in burn patients admitted to the ICU. We collected data on AKI incidence, risk factors, use of RRT, renal recovery, length of stay (LOS), mortality, and health care costs. Results We included 33 observational studies comprising 8200 patients. Overall study quality, scored according to the Newcastle-Ottawa scale, was moderate. Random effect model meta-analysis revealed that the incidence of AKI among burn patients in the ICU was 38 (30–46) %. Patients with AKI were almost evenly distributed in the mild, moderate, and severe AKI subgroups. RRT was used in 12 (8–16) % of all patients. Risk factors for AKI were high age, chronic hypertension, diabetes mellitus, high Total Body Surface Area percent burnt, high Abbreviated Burn Severity Index score, inhalation injury, rhabdomyolysis, surgery, high Acute Physiology and Chronic Health Evaluation II score, high Sequential Organ Failure Assessment score, sepsis, and mechanical ventilation. AKI patients had 8.6 (4.0–13.2) days longer ICU LOS and higher mortality than non-AKI patients, OR 11.3 (7.3–17.4). Few studies reported renal recovery, and no study reported health care costs. Conclusions AKI occurred in 38% of burn patients admitted to the ICU, and 12% of all patients received RRT. Presence of AKI was associated with increased LOS and mortality.

Introduction: The prognosis of patients suffering acute ischemic stroke (AIS) is worsened by medical complications that occur during subsequent hospitalization. The incidence, risk factors, and outcomes of gastrointestinal bowel obstruction (GIBO) in AIS have not been previously reported. Methods: We employed the Nationwide Inpatient Sample from 2002 to 2011 to identify all patients admitted with a primary diagnosis of AIS and subsets with and without a secondary diagnosis of GIBO without hernia. Multivariate logistic regression was utilized to analyze predictors of GIBO in AIS patients and the association between GIBO, in-hospital complications, and outcomes. Results: We identified 16,987 patients with GIBO (425 per 100,000) among 3,988,667 AIS hospitalizations and 4.2% of patients of these patients underwent repair surgery for intestinal obstruction. Multivariate predictors of GIBO included: age 55-64 (OR: 1.52, 95% CI: 1.40-1.64), age 65-74 (OR: 1.69, 95% CI: 1.56-1.84), age 75+ (OR: 1.97, 95% CI: 1.81-2.13), black race (OR: 1.42, 95% CI: 1.36-1.49), coagulopathy (OR: 1.39, 95% CI: 1.29-1.50), cancer (OR: 1.59, 95% CI: 1.44-1.75), blood loss anemia (OR: 2.51, 95% CI: 2.22-2.84), fluid/electrolyte disorder (OR: 2.91, 95% CI: 2.81-3.02), weight loss (OR: 3.08, 95% CI: 2.93-3.25), and thrombolytic therapy (OR: 1.30, 95% CI: 1.20-1.42) (all p<0.0001). Patients with GIBO had a greater likelihood of suffering intubation (OR: 1.79, 95% CI: 1.70-1.90), deep vein thrombosis (OR: 1.35, 95% CI: 1.25-1.46), pulmonary embolism (OR: 1.84, 95% CI: 1.53-2.21), sepsis (OR: 2.39, 95% CI: 2.22-2.56), acute kidney injury (OR: 1.85, 95% CI: 1.76-1.95), gastrointestinal hemorrhage (OR: 2.82, 95% CI: 2.63-3.03), and blood transfusions (OR: 2.02, 95% CI: 1.90-2.15) (all p<0.0001). In adjusted analyses, AIS patients with GIBO were 284% and 39% more likely to face moderate to severe disability and in-hospital death, respectively (p<0.0001). GIBO occurrence increased length of stay and total costs by an average of 9.7 days and $22,342 (p<0.0001). Conclusion: Advanced age, black race, and several pre-existing comorbidities increase the likelihood of post-AIS GIBO, which is an independent predictor of in-hospital complications, disability, and mortality.

Abstract Background and Aims Hemophagocytic lymphohistiocytosis (HLH) is a syndrome characterized by overproduction of proinflammatory cytokines and hemophagocytosis. Acute kidney injury (AKI) is the most common complication of HLH in the kidney, which is a strong predictor of poor prognosis. In this retrospective study, we aimed to find the risk factors of AKI in patients with HLH. Method We screened all adult patients with HLH admitted to West China Hospital of Sichuan University from January 2009 to June 2019. Patients in this study were secondary HLH according to the HLH diagnostic criteria revised by the Histocyte Society in 2004. Patients with HLH were excluded from the study if they had a functioning kidney transplant, received renal replacement therapy (RRT) in the past month, suffered from end-stage renal disease (ESRD), or had the renal malignant tumor. We collected basic information, clinical manifestations, and laboratory data of patients from electronic medical records. Results A total of 600 patients with confirmed diagnosis of secondary HLH are included in our analysis. There are 199(33.2%)HLH-induced AKI patients, among whom 37.2%, 32.7%, and 30.2% are classified as AKI I, II, and III, respectively, according to the 2012 KDIGO (Kidney Disease: Improving Global Outcomes) guideline. Overall hospital mortality is 176(29.3%), and the number of deaths in patients with AKI was much higher than that in patients without AKI (53.3% versus 17.5%, P &lt; 0.001). The risk factors of AKI in patients with HLH were hyperphosphatemia (P&lt;0.001, OR 5.448, 95%CI 2.951-10.059) , vasopressor(P&lt;0.001, OR 3.485, 95%CI 2.114-5.746), heart failure (P=0.044, 0R 2.336, 95%CI 1.022-5.340), gastrointestinal symptoms (P=0.043, OR 1.877, 95%CI 1.021-3.453), increased heart rate (P=0.005, OR 1.017, 95%CI 1.005-1.029), elevated total bilirubin level(P&lt;0.001, OR 1.004, 95%CI 1.002-1.007), and hypoproteinemia (P=0.034, OR 0.939, 95%CI 0.886-0.995). Conclusion The incidence of AKI was higher in patients with HLH, and the risk of death was significantly higher in HLH patients with AKI. A variety of risk factors are related to the occurrence of HLH-induced AKI. Identifying and correcting them early in clinical diagnosis and treatment may reduce the incidence of AKI in patients with HLH and improve the prognosis of them.
