<b><i>Introduction:</i></b> Acute kidney injury (AKI) is a common complication among hospitalized patients, potentially affecting short- and long-term clinical outcomes. In this retrospective study, we evaluated renal outcomes in noncritically ill patients who required acute hemodialysis (HD) because of an AKI episode occurring during hospitalization. <b><i>Methods:</i></b> Sixty-three hemodynamically stable patients with AKI undergoing acute intermittent HD were included. Kidney function was evaluated at baseline control (pre-AKI), at AKI diagnosis and during the follow-up. According to serum creatinine and the estimated glomerular filtration rate (eGFR), we defined three clinical conditions: renal recovery, different stages of acute kidney disease (AKD), and chronic kidney disease (CKD). <b><i>Results:</i></b> Among the 63 patients evaluated, 34 patients (54%) had a history of CKD. Six patients (10%) presented early full renal recovery. HD treatment was stopped in 38 patients (60%), while 25 patients (40%) required maintenance HD. Dialysis-independent patients presented lower comorbidity and higher baseline eGFR and delta creatinine, compared to dialysis-dependent patients. Baseline CKD, previous AKI episodes, and parenchymal causes of AKI were associated with a significant risk of dialysis dependence. At 1-month control, 15 patients (39%) presented AKD stage 0, 6 patients (16%) AKD stage 1, and 17 patients (44%) AKD stage 2–3. At 3-month control, 29 out of 38 patients recovering from AKI (76%) presented CKD. AKD stage was significantly correlated with the risk of CKD development, which, resulted higher in patients with lower baseline eGFR. <b><i>Conclusions:</i></b> AKI might represent a risk factor for the development of chronic kidney damage, even in noncritically ill patients.

Background: The incidence of AKI in coronavirus disease 2019 (COVID-19) patients is variable and has been associated with worse prognosis. A significant number of patients develop persistent kidney damage defined as Acute Kidney Disease (AKD). There is a lack of evidence on the real impact of AKD on COVID-19 patients. We aim to identify risk factors for the development of AKD and its impact on mortality in COVID-19 patients. Methods: Retrospective analysis of COVID-19 patients with AKI admitted at the Centro Hospitalar Universitário Lisboa Norte between March and August of 2020. The Kidney Disease Improving Global Outcomes (KDIGO) classification was used to define AKI. AKD was defined by presenting at least KDIGO Stage 1 criteria for >7 days after an AKI initiating event. Results: In 339 COVID-19 patients with AKI, 25.7% patients developed AKD (n = 87). The mean age was 71.7 ± 17.0 years, baseline SCr was 1.03 ± 0.44 mg/dL, and the majority of patients were classified as KDIGO stage 3 AKI (54.3%). The in-hospital mortality was 18.0% (n = 61). Presence of hypertension (p = 0.006), CKD (p < 0.001), lower hemoglobin (p = 0.034) and lower CRP (p = 0.004) at the hospital admission and nephrotoxin exposure (p < 0.001) were independent risk factors for the development of AKD. Older age (p = 0.003), higher serum ferritin at admission (p = 0.008) and development of AKD (p = 0.029) were independent predictors of in-hospital mortality in COVID-19-AKI patients. Conclusions: AKD was significantly associated with in-hospital mortality in this population of COVID-19-AKI patients. Considering the significant risk of mortality in AKI patients, it is of paramount importance to identify the subset of higher risk patients.

Background Acute kidney injury (AKI) and chronic kidney disease (CKD) have become worldwide public health problems, but little information is known about the epidemiology of acute kidney disease (AKD)—a state in between AKI and CKD. We aimed to explore the incidence and outcomes of hospitalized patients with AKD after AKI, and investigate the prognostic value of AKD in predicting 30-day and one-year adverse outcomes. Methods A total of 2,556 hospitalized AKI patients were identified from three tertiary hospitals in China in 2015 and followed up for one year.AKD and AKD stage were defined according to the consensus report of the Acute Disease Quality Initiative 16 workgroup. Multivariable regression analyses adjusted for confounding variables were used to examine the association of AKD with adverse outcomes. Results AKD occurred in 45.4% (1161/2556) of all AKI patients, 14.5% (141/971) of AKI stage 1 patients, 44.6% (308/691) of AKI stage 2 patients and 79.6% (712/894) of AKI stage 3 patients. AKD stage 1 conferred a greater risk of Major Adverse Kidney Events within 30 days (MAKE30) (odds ratio [OR], 2.36; 95% confidence interval 95% CI [1.66–3.36]) than AKD stage 0 but the association only maintained in AKI stage 3 when patients were stratified by AKI stage. However, compared with AKD stage 0, AKD stage 2–3 was associated with higher risks of both MAKE30 and one-year chronic dialysis and mortality independent of the effects of AKI stage with OR being 31.35 (95% CI [23.42–41.98]) and 2.68 (95% CI [2.07–3.48]) respectively. The association between AKD stage and adverse outcomes in 30 days and one year was not significantly changed in critically ill and non-critically ill AKI patients. The results indicated that AKD is common among hospitalized AKI patients. AKD stage 2–3 provides additional information in predicting 30-day and one-year adverse outcomes over AKI stage. Enhanced follow-up of renal function of these patients may be warranted.

Abstract Background and Aims Acute kidney injury (AKI) is observed in more than 50% of patients admitted in intensive care units (ICU) and more than 10% of them require renal replacement therapy (RRT) Acute kidney disease (AKD) has been recently proposed to describe a highly vulnerable period with pathophysiological process following AKI during which the patient could experience a decline in glomerular filtration and finally developed CKD. Patients suffering from AKI in ICU could have various renal trajectories and outcomes (early, late, or absence of recovery; early or late relapse; acute kidney disease (AKD); or chronic kidney disease (CKD)) after discharge. No cohort study described them accurately. Aims were to assess the various clinical trajectories after AKI in ICU and to determine risk factors for developing CKD taking into account the new concept of AKD and to assess the long-term incidence of CKD. Method We conducted a prospective five-year follow-up study in a medical ICU in Bordeaux University Hospital (France). The patients who received invasive mechanical ventilation, catecholamine infusion or both and developed an AKI (defined by KDIGO criteria) from September 2013 to May 2015 were included. We excluded the patients with a previous estimated glomerular filtration rate (eGFR) of &lt;90mL/min/1.73m2. AKD was defined as a condition wherein the criteria for AKI stage 1 or greater persists ≥7 days after exposure. CKD was defined by an eGFR of &lt;60ml/min/1.73m2 at least 90 days after the AKI. Renal recovery was defined by serum creatinine ≤125% of serum basal creatinine. Using the Aalen-Johansen estimator to account for competing risks, we estimated the cumulative incidence of CKD. To estimate adjusted hazard ratios (HRs) we used standard Cox proportional hazard models adjusted for age, sex, hypertension, diabetes, cardiovascular history, SOFA and AKI stage. Proportional hazard assumptions were checked using Schoenfeld residuals. Violation of proportional hazard assumption for AKD was handled by using appropriate interaction terms with time, resulting in time-dependent HR. Results 232 patients were enrolled. The age was 62 ± 16 years, 142/232 (61%) were male. AKI stage 1 was present in 62/232 (27%) patients, AKI stage 2 in 50/232 (21%), and AKI stage 3 in 120/232 (52%). Among patients with AKI, 65/232 (28%) recovered before day 7. At day 7, 106/232 (46%) had been progressing to AKD. AKD also developed secondary in 3/65 because of a second episode of AKI without recovery. Among the AKD patients, 21/109 (19%) recovered before day 90, 41/109 (38%) dead and 47/109 (43%) progressed to CKD (figure). The cumulative incidence of CKD was 17 [12-21]% at 1-year follow-up and 30 [24-36] % at 5-years follow-up. This incidence was higher in AKD-patients (44 [35-54]%, and 48 [39-58]%) than in non-AKD patients (9 [1-16]% and 22 [10-34]%) after 1 and 5 years of follow-up, respectively (p=6.10-5). The risk of developing CKD in AKD-patients was increased up to six months compared to those without AKD (HR 27.1 [7.9-93.5]; p&lt;0.0001). Six months after AKI, the risk of progression to CKD was not statistically different between AKD patients and non-AKD patients (HR 2.45 [0.68 – 8.85]; p = 0.17). In this model only gender (male sex: HR 0.5 [0.3-0.9]; p= 0.02) was also significantly associated with CKD. Conclusion There were many clinical trajectories after AKI in ICU. Risk for developing CKD remained during the 5 years of follow-up. AKD was the main risk factors for developing CKD only in the first 6 months. After, the risk was similar in AKD or non-AKD patients. Female gender was associated with CKD during all the follow-up. These patients need a specific follow-up after ICU discharge.

Long Term Mortality

Abstract Background Acute kidney injury (AKI) is frequent during hospitalization and may contribute to adverse short- and long-term consequences. Acute kidney disease (AKD) reflects the continuing pathological processes and adverse events developing after AKI. We aimed to evaluate the association of AKD, long-term adverse renal function and mortality in a cohort of patients with sepsis. Methods We performed a retrospective analysis of adult patients with septic AKI admitted to the Division of Intensive Medicine of the Centro Hospitalar Lisboa Norte (Lisbon, Portugal) between January 2008 and December 2014. Patients were categorized according to the development of AKI using the Kidney Disease: Improving Global Outcomes (KDIGO) classification. AKI was defined as an increase in absolute serum creatinine (SCr) ≥0.3 mg/dL or by a percentage increase in SCr ≥50% and/or by a decrease in urine output to &lt;0.5 mL/kg/h for &gt;6 h. AKD was defined as presenting at least KDIGO Stage 1 criteria for &gt;7 days after an AKI initiating event. Adverse renal outcomes (need for long-term dialysis and/or a 25% decrease in estimated glomerular filtration rate after hospital discharge) and mortality after discharge were evaluated. Results From 256 selected patients with septic AKI, 53.9% developed AKD. The 30-day mortality rate was 24.5% (n = 55). The mean long-term follow-up was 45.9 ± 43.3 months. The majority of patients experience an adverse renal outcome [n = 158 (61.7%)] and 44.1% (n = 113) of patients died during follow-up. Adverse renal outcomes, 30-day mortality and long-term mortality after hospital discharge were more frequent among AKD patients [77.5 versus 43.2% (P &lt; 0.001), 34.1 versus 6.8% (P &lt; 0.001) and 64.8 versus 49.1% (P = 0.025), respectively]. The 5-year cumulative probability of survival was 23.2% for AKD patients, while it was 47.5% for patients with no AKD (log-rank test, P &lt; 0.0001). In multivariate analysis, AKD was independently associated with adverse renal outcomes {adjusted hazard ratio [HR] 2.87 [95% confidence interval (CI) 2.0–4.1]; P &lt; 0.001} and long-term mortality [adjusted HR 1.51 (95% CI 1.0–2.2); P = 0.040]. Conclusions AKD after septic AKI was independently associated with the risk of long-term need for dialysis and/or renal function decline and with the risk of death after hospital discharge.

Atrial fibrillation (AF) symptoms may mimic coronary artery disease (CAD) which reflects the difficulties in qualifying AF patients for invasive diagnostics. A substantial number of coronary angiographies may be unnecessary or even put patients at risk of post-contrast acute kidney injury (PC-AKI), especially patients with chronic kidney disease (CKD). We aimed to investigate the hypothesis indicating higher prevalence of PC-AKI in patients with AF scheduled for coronary angiography. The study population comprised of 8026 patients referred for elective coronarography including 1621 with AF. In the comparison of prevalence of PC-AKI in distinguished groups we can see that kidney impairment was twice more frequent in patients with AF in both groups with CKD (CKD (+)/AF (+) 6.24% vs. CKD (+)/AF (−) 3.04%) and without CKD (CKD (−)/AF (+) 2.32% vs. CKD (−)/AF (−) 1.22%). In our study, post-contrast acute kidney disease is twice more frequent in patients with AF, especially in subgroup with chronic kidney disease scheduled for coronary angiography. Additionally, having in mind results of previous studies stating that AF is associated with non-obstructive coronary lesions on angiography, patients with AF and CKD may be unnecessarily exposed to contrast agent and possible complications.

Background: The aim of this study was to examine different definitions of renal recovery following postoperative acute kidney injury (AKI) and how these definitions associate with survival and the development and progression of chronic kidney disease (CKD). Methods: This was a retrospective study of all patients who underwent abdominal, cardiothoracic, vascular, or orthopedic surgery at a single university hospital between 1998 and 2015. Recovery of renal function following postoperative AKI was assessed comparing 4 different definitions: serum creatinine (SCr) (i) < 1.1 × baseline, (ii) 1.1–1.25 × baseline, (iii) 1.25–1.5 × baseline, and (iv) > 1.5 × baseline. One-year survival and the development or progression of CKD within 5 years was compared with a propensity score-matched control groups. Results: In total, 2,520 AKI patients were evaluated for renal recovery. Risk of incident and progressive CKD within 5 years was significantly increased if patients did not achieve a reduction in SCr to < 1.5 × baseline (hazard ratio [HR] 1.50; 95% CI 1.29–1.75) and if renal recovery was limited to a fall in SCr to 1.25–1.5 × baseline (HR 1.32; 95% CI 1.12–1.57) within 30 days. The definition of renal recovery that best predicted survival was a reduction in SCr to < 1.5 × baseline within 30 days. One-year survival of patients whose SCr decreased to < 1.5 × baseline within 30 days was significantly better than that of a propensity score-matched control group that did not achieve renal recovery (85 vs. 71%, p < 0.001). Conclusions: These findings should be considered when a consensus definition of renal recovery after AKI is established.

ABSTRACT Objective: to evaluate the nursing workload in intensive care patients with acute kidney injury (AKI). Method: A quantitative study, conducted in an intensive care unit, from April to August of 2015. The Nursing Activities Score (NAS) and Kidney Disease Improving Global Outcomes (KDIGO) were used to measure nursing workload and to classify the stage of AKI, respectively. Results: A total of 190 patients were included. Patients who developed AKI (44.2%) had higher NAS when compared to those without AKI (43.7% vs 40.7%), p <0.001. Patients with stage 1, 2 and 3 AKI showed higher NAS than those without AKI. A relationship was identified between stage 2 and 3 with those without AKI (p = 0.002 and p <0.001). Conclusion: The NAS was associated with the presence of AKI, the score increased with the progression of the stages, and it was associated with AKI, stage 2 and 3.
