Severe acute kidney injury in COVID-19 patients is associated with in-hospital mortality

Although the lungs are major targets for COVID-19 invasion, other organs—such as the kidneys—are also affected. However, the renal complications of COVID-19 are not yet well explored. This study aimed to identify the incidence of acute kidney injury (AKI) in patients with COVID-19 and to evaluate its impact on patient outcomes. This retrospective study included 704 patients with COVID-19 who were hospitalized at two hospitals in Daegu, Korea from February 19 to March 31, 2020. AKI was defined according to the serum creatinine criteria in the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines. The final date of follow-up was May 1, 2020. Of the 704 patients, 28 (4.0%) developed AKI. Of the 28 patients with AKI, 15 (53.6%) were found to have AKI stage 1, 3 (10.7%) had AKI stage 2, and 10 (35.7%) had AKI stage 3. Among these patients, 12 (42.9%) recovered from AKI. In the patients with AKI, the rates of admission to intensive care unit (ICU), administration of mechanical ventilator (MV), and in-hospital mortality were significantly higher than in patients without AKI. Multivariable analysis revealed that old age (Hazard ratio [HR] = 4.668, 95% confidence interval [CI] = 1.250–17.430, p = 0.022), high neutrophil-to-lymphocyte ratio (HR = 1.167, 95% CI = 1.078–1.264, p < 0.001), elevated creatinine kinase (HR = 1.002, 95% CI = 1.001–1.004, p = 0.007), and severe AKI (HR = 12.199, 95% CI = 4.235–35.141, p < 0.001) were independent risk factors for in-hospital mortality. The Kaplan-Meier curves showed that the cumulative survival rate was lowest in the AKI stage 3 group (p < 0.001). In conclusion, the incidence of AKI in patients with COVID-19 was 4.0%. Severe AKI was associated with in-hospital death.

Abstract Background:Understanding of the incidence and effects of acute kidney injury (AKI) in patients diagnosed with COVID-19 is limited. The purpose of this study was to examine risk factors and related outcomes associated with AKI among patients diagnosed with COVID-19. Method: This is a retrospective cohort study of patients diagnosed with COVID-19 associated-pneumonia admitted to a tertiary hospital in Wuhan between January to February 2020. AKI was defined and staged according to the Kidney Disease: Improving Global Outcome (KDIGO) classification criteria. Cox’s multivariate regression and logistic regression modelling were used to assess the effects of AKI on hospital mortality and risk factors associated with occurrence of AKI. Primary outcomes were risk-adjusted in-hospital mortality.Results:342 patients were finally enrolled in this study. AKI occurred in 13.4% (n = 46), among them 7.0% (n = 24) developed stage 1AKI, and 6.4% (n = 22) developed stage 2 - 3 AKI. Overall 26.9% (n = 92) died during hospitalization. Among them 19.3% (57/296) of the non-AKI patients died, 62.5%(15/24) of stage 1 AKI patients, and 90.9% (20/22) of stage 2 - 3 AKI patients died. AKI was strongly associated with mortality (HR 2.52; 95% CI, 1.59-3.96; p＜0.001). Further analysis shows that progression to AKI stage 2 - 3 doubles the hazard ratio for death. Age, leukocytes number, fibrinogen concentration, C-reative protein level, and severity of pneumonia at admission were independent risk factors associated with the development of AKI. Conclusion:Acute kidney injury is common among hospitalized COVID-19 patients and strongly associated with increased mortality, early detection and prevention of the progression of AKI may be critical to reduce mortality of these patients.

Abstract Background. Acute kidney injury (AKI) is a well recognized complication of severe malaria in adults, but the incidence and clinical importance of AKI in pediatric severe malaria (SM) is not well documented. Methods. One hundred eighty children aged 1 to 10 years with SM were enrolled between 2011 and 2013 in Uganda. Kidney function was monitored daily for 4 days using serum creatinine (Cr). Acute kidney injury was defined using the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines. Blood urea nitrogen (BUN) and Cr were assessed using i-STAT, and cystatin C (CysC) was measured by enzyme-linked immunosorbent assay. Results. Eighty-one (45.5%) children had KDIGO-defined AKI in the study: 42 (51.9%) stage 1, 18 (22.2%) stage 2, and 21 (25.9%) stage 3. Acute kidney injury evolved or developed in 50% of children after admission of hospital. There was an increased risk of AKI in children randomized to inhaled nitric oxide (iNO), with 47 (54.0%) of children in the iNO arm developing AKI compared with 34 (37.4%) in the placebo arm (relative risk, 1.36; 95% confidence interval [CI], 1.03–1.80). Duration of hospitalization increased across stages of AKI (P = .002). Acute kidney injury was associated with neurodisability at discharge in the children receiving placebo (25% in children with AKI vs 1.9% in children with no AKI, P = .002). Mortality increased across stages of AKI (P = .006) in the placebo arm, reaching 37.5% in stage 3 AKI. Acute kidney injury was not associated with neurodisability or mortality at discharge in children receiving iNO (P > .05 for both). Levels of kidney biomarkers were predictive of mortality with areas under the curves (AUCs) of 0.80 (95% CI, .65–.95; P = .006) and 0.72 (95% CI, .57–.87; P < .001), respectively. Admission levels of CysC and BUN were elevated in children who died by 6 months (P < .0001 and P = .009, respectively). Conclusions. Acute kidney injury is an underrecognized complication in young children with SM and is associated with increased mortality.

Introduction: Acute kidney injury (AKI) is strongly associated with poor outcomes in hospitalized patients with coronavirus disease 2019 (COVID-19), but data on the association of proteinuria and hematuria are limited to non-US populations. In addition, admission and in-hospital measures for kidney abnormalities have not been studied separately. Methods: This retrospective cohort study aimed to analyze these associations in 321 patients sequentially admitted between March 7, 2020 and April 1, 2020 at Stony Brook University Medical Center, New York. We investigated the association of proteinuria, hematuria, and AKI with outcomes of inflammation, intensive care unit (ICU) admission, invasive mechanical ventilation (IMV), and in-hospital death. We used ANOVA, t test, χ2 test, and Fisher’s exact test for bivariate analyses and logistic regression for multivariable analysis. Results: Three hundred patients met the inclusion criteria for the study cohort. Multivariable analysis demonstrated that admission proteinuria was significantly associated with risk of in-hospital AKI (OR 4.71, 95% CI 1.28–17.38), while admission hematuria was associated with ICU admission (OR 4.56, 95% CI 1.12–18.64), IMV (OR 8.79, 95% CI 2.08–37.00), and death (OR 18.03, 95% CI 2.84–114.57). During hospitalization, de novo proteinuria was significantly associated with increased risk of death (OR 8.94, 95% CI 1.19–114.4, p = 0.04). In-hospital AKI increased (OR 27.14, 95% CI 4.44–240.17) while recovery from in-hospital AKI decreased the risk of death (OR 0.001, 95% CI 0.001–0.06). Conclusion: Proteinuria and hematuria both at the time of admission and during hospitalization are associated with adverse clinical outcomes in hospitalized patients with COVID-19.

Abstract Objectives: Although the respiratory and immune systems are the major targets of SARS-CoV-2, increasing evidence revealed that kidney injury was not rare in coronavirus disease 2019 (COVID-19). However, the incidences of kidney abnormalities were significantly different, from 0.5 to 75.4% in several reports. The association of kidney injury with prognosis remain controversial.Methods:In this retrospective single center cohort study, laboratory confirmedCOVID-19inpatients with severe type were enrolled. Demographic, clinicaland laboratory data were collected. Association ofserum creatinine (SCr)with 28-days mortality in severe COVID-19 patients was analyzed.Results:18.79% (48/304) patients died during the first 28-days of hospitalization.Non-survivors had a significantly higher SCr levels than survivors (109.27μmol/L vs. 69.99μmol/L, P <0.001). The 28-days mortality in high SCr group (>76μmol/L) was significantly higher than that in low SCr group (31.7% vs. 7.5%, P <0.001). Multivariate logistic regression revealed that the independent risk factors of 28-days outcome included age(OR: 2.95, 95%CI: 1.08-8.05), WBC (OR: 6.09, 95%CI: 2.27-6.39), lymphopenia (OR: 3.49, 95%CI: 1.55-7.92), IL-6 (OR: 4.44, 95%CI: 1.64-11.99) and SCr (OR: 2.69, 95%CI: 1.18-6.11). Kaplan-Meier analysis demonstrated the survival disadvantage in patients with high SCr levels (>76μmol/L). ROC curve showed the SCr cut-off value for predicting 28-days death was 77.5 μmol/L, with the sensitivity of 68.8% and speciality of 74.1%.Conclusion: SCr was associated with poor prognosis and might be an independent risk factor for in-hospital death. The cut-off value of SCr for prognosis prediction was 77.5 μmol/L, with the sensitivity of 68.8% and speciality of 74.1%.

Background: Elevated blood pressure (BP) in the first 24 hours of admission of acute intracerebral hemorrhage (ICH) has been the focus of intensive therapeutic investigation, although early intensive BP lowering addresses a concern about development of acute kidney injury (AKI). However, it is unclear as to the effect of BP measure including the absolute BP reduction and increased BP variability on AKI in patients with acute ICH. Methods: We retrieved data of consecutive patients with acute ICH from our prospective stroke registry between July 2015 and August 2017. We excluded patients with preexisting end-stage renal disease or in-hospital death within 24 hours. The primary outcome was AKI within 7days after admission defined using the AKI Network criteria. We recorded BP on emergency department arrival and for every 1 hour from 1 to 24 hours after admission (25 measurements). We measured mean systolic BP (SBP) and maximum minus minimum SBP within both 12 hours and 24 hours, and also quantified SBP variabilities (SBPV) including standard deviation, coefficient of variation, successive variation, and average real variability. Results: Among 361 patients with ICH (age 72.7±12.8, male 55%, non-lobar 76%), 31 (9%) developed AKI. For all SBP measure, the 12-hour SBP reduction was associated with the increased risk of AKI in multivariable analysis (odds ratio [per10 mmHg increase] 1.30; 95% CI 1.10-1.35). There was no significant association between the SBP variability and risk of AKI. The area under the receiver operating characteristic curve of the 12-hour SBP reduction for predicting AKI was 0.75. The association between the 12-hour SBP reduction and AKI was not modified by preexisting chronic kidney disease (interaction P=0.40). Conclusion: Early BP reduction in the first 12 hours of admission contributed to the risk of AKI in acute ICH. This may have clinical implication to avoid excess absolute BP reduction in patients with acute ICH.

Abstract Background and Aims Acute kidney injury (AKI) is a major risk factor for development and progression to chronic kidney disease (CKD). The aim of the present study is to assess the incidence of infections after an admission for AKI. Method In this retrospective study all patients who developed AKI during hospitalization and were discharged from 2013 to 2014 were included. Factors associated to infections were evaluated. The mean follow-up after discharge was 39±30 months. Results We included 1255 patients with a mean age of 75±13 years, of which 692 (55%) were men. At baseline, 944 (75%) patients presented with hypertension, 379 (30%) with diabetes, 560 (44%) with hypercholesterolemia and 543 (43%) with CKD. Mean baseline creatinine was 1,3±1,8 mg/dl (glomerular filtration rate [eGFR] estimated by CKD-EPI was 55±25 ml/min/1,73m2). The peak level of creatinine reached during AKI was 2,47±1,97 mg/dl (eGFR 30±18 ml/min/1,73m2). At discharge, creatinine was 1,62 mg/dL and eGFR 53±27 ml/min/1,73m2. Seven hundred and seventy-three (62%) patients presented an eGFR inferior to 60 ml/min/1,73m2. During follow-up, 681(54%) patients presented an infectious event. Urinary tract infection was the most frequent infection (286 patients, 23%) followed by respiratory infection (214 patients, 17%). Factors associated with infection were age (p<0,001), hypertension (p=0,03), atrial fibrillation (p=0,014), functional dependence measured by Barthel index (p=0,03), previous diagnosis of CKD (p=0,01), baseline eGFR (p>0,001) and eGFR at discharge (p=0,002). Survival analysis using Kaplan-Meier demonstrated an existing association between eGFR inferior to 60 ml/min/1,73m2 and infections (LogRank 12,2, p<0,001, figure 1). Adjusted multivariable analysis demonstrated that age (HR 1,01 [CI95% 1,00-1,02], p=0,009) and the presence of eGFR inferior to 60 ml/min/1,73 m2 (HR 1,45 [CI95% 1,04-2,02], p=0,02) were independent predictors of infection after AKI episode. Conclusion The existence of eGFR inferior to 60 ml/min/1,73 m2 after an hospitalization with AKI shows an independent association with presenting an infection afterwards.

The aim of the study is to diagnose acute kidney injury, its severity, and types in patients with pulmonary artery thromboembolia (PATE), to establish the correlation between AKI and the estimated mortality risk, hospital mortality. Materials and Methods. The study enrolled 111 patients (61 males (55 %), and 50 females (45 %), average age 66.8±11.7 years) with PATE, hospitalized to the cardiology department of Ulyanovsk Central City Clinical Hospital. Results. Acute kidney injury was diagnosed in 36 patients with PATE (34 %): among them 24 patients with stage 1 PATE (67 %); 7 patients with stage 2 (19 %); 5 patients with stage 3 (14 %). Prehospital complications were diagnosed in 20 patients (56 %), hospital AKI was detected in 16 patients (44 %). CKD-associated AKI was observed in 24 patients (67 %), de novo AKI was diagnosed in 12 trial subjects (33 %). Twenty-six patients (23 %) died during hospitalization. The relative hospital mortality risk in AKI patients was 5.2 (95 % CI: 2.02–13.39; p<0.001). The estimated risk of 30-day mortality according to the PESI score was higher in AKI patients (120.0 (87.5–158,0) and 90 (87.5-158.0), respectively, p=0.004). Conclusion. Patients with PATE had a high incidence of AKI, which was diagnosed in every 3rd patient. In 67 % of patients, AKI was associated with chronic kidney disease. Patients with prehospital AKI prevailed (56 %). AKI in patients with PATE was associated with increased in-hospital mortality and an estimated 30-day mortality risk. Keywords: acute kidney injury, pulmonary embolism, hospital mortality, estimated mortality risk. Цель исследования. Оценить наличие, степень выраженности и варианты острого повреждения почек (ОПП) у пациентов с тромбоэмболией легочной артерии (ТЭЛА); уточнить связь между ОПП и расчетным риском смерти, госпитальной летальностью. Материалы и методы. Обследовано 111 пациентов (мужчин – 61 (55 %), женщин – 50 (45 %), средний возраст – 66,8±11,7 года) с ТЭЛА, госпитализированных в отделение кардиологии ГУЗ «Центральная городская клиническая больница г. Ульяновска». Результаты. Острое повреждение почек диагностировано у 36 (34 %) пациентов с ТЭЛА, причем у 24 (67 %) из них выявлена 1 стадия, у 7 (19 %) – 2 стадия и у 5 (14 %) – 3 стадия. У 20 (56 %) пациентов диагностирован догоспитальный вариант осложнения, госпитальное ОПП выявлялось в 16 (44 %) случаях. ОПП при ХБП имело место у 24 (67 %) обследованных, ОПП de novo – у 12 (33 %). В период госпитализации умерло 26 (23 %) пациентов. Относительный риск смерти в стационаре у пациентов с ОПП составил 5,2 (95 % ДИ: 2,02–13,39; р<0,001). Расчетный риск 30-дневной смерти по шкале PESI при наличии ОПП был выше, чем при его отсутствии (120,0 (87,5–158,0) и 90 (87,5–158,0) соответственно, p=0,004). Выводы. У пациентов с ТЭЛА наблюдается высокая частота ОПП, оно диагностируется у каждого 3-го пациента. У 67 % пациентов острое повреждение почек развивается на фоне предшествующей хронической болезни почек. Преобладают пациенты с догоспитальным ОПП (56 %). Острое повреждение почек у пациентов с ТЭЛА ассоциировано с увеличением госпитальной летальности и расчетного риска 30-дневной смертности. Ключевые слова: острое повреждение почек, тромбоэмболия легочной артерии, госпитальная летальность, расчетный риск смерти.

Acute kidney injury (AKI) is a frequent complication of hospitalized patients with infective endocarditis (IE). Further, AKI in the setting of IE is associated with high morbidity and mortality. We aimed to examine the incidence, clinical parameters, and hospital costs associated with AKI in hospitalized patients with IE in an endemic area with an increasing prevalence of opioid use. This retrospective cohort study included 269 patients admitted to a major referral center in Kentucky with a primary diagnosis of IE from January 2013 to December 2015. Of these, 178 (66.2%) patients had AKI by Kidney Disease Improving Global Outcomes (KDIGO) serum creatinine criteria: 74 (41.6%) had AKI stage 1 and 104 (58.4%) had AKI stage ≥2. In multivariable analysis, higher comorbidity scores and the need for diuretics were independently associated with AKI, while the involvement of the tricuspid valve and the need for vasopressor/inotrope support were independently associated with severe AKI (stage ≥2). The median total direct cost of hospitalization was progressively higher according to each stage of AKI ($17,069 for no AKI; $37,111 for AKI stage 1; and $61,357 for AKI stage ≥2; p < 0.001). In conclusion, two-thirds of patients admitted to the hospital due to IE had incident AKI. The occurrence of AKI significantly increased healthcare costs. The higher level of comorbidity, the affection of the tricuspid valve, and the need for diuretics and/or vasoactive drugs were associated with severe AKI in this susceptible population.

Background: Coronavirus disease 2019 (COVID-19) has emerged as a major global health threat with a great number of deaths worldwide. Acute kidney injury (AKI) is a common complication in patients admitted to the intensive care unit. We aimed to assess the incidence, risk factors and in-hospital outcomes of AKI in COVID-19 patients admitted to the intensive care unit. Methods: We conducted a retrospective observational study in the intensive care unit of Tongji Hospital, which was assigned responsibility for the treatments of severe COVID-19 patients by the Wuhan government. AKI was defined and staged based on Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Mild AKI was defined as stage 1, and severe AKI was defined as stage 2 or stage 3. Logistic regression analysis was used to evaluate AKI risk factors, and Cox proportional hazards model was used to assess the association between AKI and in-hospital mortality. Results: A total of 119 patients with COVID-19 were included in our study. The median patient age was 70 years (interquartile range, 59–77) and 61.3% were male. Fifty-one (42.8%) patients developed AKI during hospitalization, corresponding to 14.3% in stage 1, 28.6% in stage 2 and 18.5% in stage 3, respectively. Compared to patients without AKI, patients with AKI had a higher proportion of mechanical ventilation mortality and higher in-hospital mortality. A total of 97.1% of patients with severe AKI received mechanical ventilation and in-hospital mortality was up to 79.4%. Severe AKI was independently associated with high in-hospital mortality (OR: 1.82; 95% CI: 1.06–3.13). Logistic regression analysis demonstrated that high serum interleukin-8 (OR: 4.21; 95% CI: 1.23–14.38), interleukin-10 (OR: 3.32; 95% CI: 1.04–10.59) and interleukin-2 receptor (OR: 4.50; 95% CI: 0.73–6.78) were risk factors for severe AKI development. Conclusions: Severe AKI was associated with high in-hospital mortality, and inflammatory response may play a role in AKI development in critically ill patients with COVID-19.

Background: Sepsis is a complex clinical syndrome leading to severe sepsis and septic shock. It is very common in the intensive care unit with high mortality. Thus, judging its prognosis is extremely important. Procalcitonin (PCT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels are commonly elevated in sepsis patients, but only a few are discussed in the septic acute kidney injury patients (AKI) who received renal replacement therapy (RRT). Our study is aimed at investigating the prognostic value of PCT and NT-proBNP in septic AKI patients who received RRT. Methods: This was a retrospective study of septic AKI patients who underwent RRT in a Chinese university hospital. All enrolled patients tested PCT and NT-proBNP at RRT initiation. PCT and NT-proBNP levels were compared between the survivors and non-survivors. Receiver operating characteristic (ROC) curves of the 2 biomarkers were performed for predicting in-hospital mortality. According to the median value of PCT (16.2 ng/mL) and NT-proBNP (10,271 pg/mL), patients were divided into 4 groups (low PCT and low NT-proBNP; high PCT and low NT-proBNP; low PCT and high NT-proBNP; high PCT and high NT-proBNP). The Kaplan-Meier survival curves were used to analyze the 28-day survival rate in the 4 groups. Results: A total of 81 patients were enrolled in the study. Of which, 48 (59.3%) patients died during hospitalization. The median of NT-proBNP in non-survivors was significantly higher than in survivors (p = 0.001), while PCT had no significant difference (p = 0.412). The area under the ROC curve of PCT and NT-proBNP for predicting in-hospital mortality was 0.561 (95% CI 0.426–0.695) and 0.729 (95% CI 0.604–0.854). Kaplan-Meier survival curve analysis showed that increased NT-proBNP level was associated with 28-day mortality while combined with PCT there was no statistical difference in 4 different level groups. Conclusion: NT-proBNP has a certain predictive value for the prognosis in septic AKI patients who received RRT. It seems that the initial PCT value for prognosis is limited. The combination of PCT and NT-proBNP to evaluate the prognosis in these critically ill patients is currently unclear.
