Abstract Background Acute kidney injury (AKI) is common among patients hospitalised with COVID-19 and associated with worse prognosis. The aim of this study was to investigate the epidemiology, risk factors and outcomes of AKI in patients with COVID-19 in a large UK tertiary centre. Methods We analysed data of consecutive adults admitted with a laboratory-confirmed diagnosis of COVID-19 across two sites of a hospital in London, UK, from 1st January to 13th May 2020. Results Of the 1248 inpatients included, 487 (39%) experienced AKI (51% stage 1, 13% stage 2, and 36% stage 3). The weekly AKI incidence rate gradually increased to peak at week 5 (3.12 cases/100 patient-days), before reducing to its nadir (0.83 cases/100 patient-days) at the end the study period (week 10). Among AKI survivors, 84.0% had recovered renal function to pre-admission levels before discharge and none required on-going renal replacement therapy (RRT). Pre-existing renal impairment [odds ratio (OR) 3.05, 95%CI 2.24–4,18; p <  0.0001], and inpatient diuretic use (OR 1.79, 95%CI 1.27–2.53; p <  0.005) were independently associated with a higher risk for AKI. AKI was a strong predictor of 30-day mortality with an increasing risk across AKI stages [adjusted hazard ratio (HR) 1.59 (95%CI 1.19–2.13) for stage 1; p < 0.005, 2.71(95%CI 1.82–4.05); p < 0.001for stage 2 and 2.99 (95%CI 2.17–4.11); p < 0.001for stage 3]. One third of AKI3 survivors (30.7%), had newly established renal impairment at 3 to 6 months. Conclusions This large UK cohort demonstrated a high AKI incidence and was associated with increased mortality even at stage 1. Inpatient diuretic use was linked to a higher AKI risk. One third of survivors with AKI3 exhibited newly established renal impairment already at 3–6 months.

One third of AKI3 survivors (30.7%), had newly established renal impairment at 3 to 6 months. Conclusions: This large UK cohort demonstrated a high AKI incidence with a changing pattern over time and was associated with increased mortality even at stage 1. Inpatient diuretic use was linked to a higher AKI risk. One third of survivors with AKI3 exhibited newly established renal impairment already at 3-6 months.

Introduction: Acute kidney injury is a frequent complication after transcatheter aortic valve implantation with great impact on morbidity and mortality. It is important to identify modifiable risk factors in order to develop preventive strategies. The aim of the study is to determine acute kidney injury incidence, risk factors and impact in patients that underwent transcatheter aortic valve implantation.Material and Methods: Retrospective study in 149 consecutive patients that underwent transcatheter aortic valve implantation at Santa Marta Hospital. The data was collected from the periprocedural records and stratified by the occurrence of acute kidney injury according to the AKIN classification.Results: A total of 149 patients, 43.0% male with median age 82.00 [77.50 – 85.00] years were included in the study. Incidence of acute kidney injury was 14.8% (n = 22). Female patients (OR 0.138, CI 95%; 0.022 – 0.854; p = 0.033) had a higher risk of that complication. Patients with acute kidney injury had longer hospitalizations (OR 1.043, CI 95%; 1.001 – 1.085; p = 0.043); acute kidney injury was associated with increased 30 day mortality (OR 13.889, 95% CI; 2.371 – 81.363; p = 0.004).Discussion: Acute kidney injury is associated with preprocedural variables and is a determinant of morbimortality. However, the retrospective character and the reduced sample size didn’t allow the determination of the precise weight of each factor.Conclusion: Acute kidney injury is a complication after transcatheter aortic valve implantation which played a significant role in morbimortality justifying its prevention.

Background COVID-19 is a multisystemic disorder that frequently causes acute kidney injury (AKI). However, the precise clinical and biochemical variables associated with AKI progression in patients with severe COVID-19 remain unclear. Methods We performed a retrospective study on 278 hospitalized patients who were admitted to the ward and intensive care unit (ICU) with COVID-19 between March 2020 and June 2020, at the University Hospital, São Paulo, Brazil. Patients aged ≥ 18 years with COVID-19 confirmed on RT-PCR were included. AKI was defined according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria. We evaluated the incidence of AKI, several clinical variables, medicines used, and outcomes in two sub-groups: COVID-19 patients with AKI (Cov-AKI), and COVID-19 patients without AKI (non-AKI). Univariate and multivariate analyses were performed. Results First, an elevated incidence of AKI (71.2%) was identified, distributed across different stages of the KDIGO criteria. We further observed higher levels of creatinine, C-reactive protein (CRP), leukocytes, neutrophils, monocytes, and neutrophil-to-lymphocyte ratio (NLR) in the Cov-AKI group than in the non-AKI group, at hospital admission. On univariate analysis, Cov-AKI was associated with older age (>62 years), hypertension, CRP, MCV, leucocytes, neutrophils, NLR, combined hydroxychloroquine and azithromycin treatment, use of mechanical ventilation, and vasoactive drugs. Multivariate analysis showed that hypertension and the use of vasoactive drugs were independently associated with a risk of higher AKI in COVID-19 patients. Finally, we preferentially found an altered erythrocyte and leukocyte cellular profile in the Cov-AKI group compared to the non-AKI group, at hospital discharge. Conclusions In our study, the development of AKI in patients with severe COVID-19 was related to inflammatory blood markers and therapy with hydroxychloroquine/azithromycin, with vasopressor requirement and hypertension considered potential risk factors. Thus, attention to the protocol, hypertension, and some blood markers may help assist doctors with decision-making for the management of COVID-19 patients with AKI.
