<b><i>Background:</i></b> Information on older patients with hospital-acquired acute kidney injury (HA-AKI) and use of drugs is limited. <b><i>Aim:</i></b> This study aimed to assess the clinical characteristics, drug uses, and in-hospital outcomes of hospitalized older patients with HA-AKI. <b><i>Methods:</i></b> Patients aged ≥65 years who were hospitalized in medical wards were retrospectively analyzed. The study patients were divided into the HA-AKI and non-AKI groups based on the changes in serum creatinine. Disease incidence, risk factors, drug uses, and in-hospital outcomes were compared between the groups. <b><i>Results:</i></b> Of 26,710 older patients in medical wards, 4,491 (16.8%) developed HA-AKI. Older patients with HA-AKI had higher rates of multiple comorbidities and Charlson Comorbidity Index score than those without AKI (<i>p</i> &#x3c; 0.001). In the HA-AKI group, the proportion of patients with prior use of drugs with possible nephrotoxicity was higher than that of patients with prior use of drugs with identified nephrotoxicity (<i>p</i> &#x3c; 0.05). The proportions of patients with critical illness, use of nephrotoxic drugs, and the requirements of intensive care unit treatment, cardiopulmonary resuscitation, and dialysis as well as in-hospital mortality and hospitalization duration and costs were higher in the HA-AKI than the non-AKI group; these increased with HA-AKI severity (all <i>p</i> for trend &#x3c;0.001). With the increase in the number of patients with continued use of drugs with possible nephrotoxicity after HA-AKI, the clinical outcomes showed a tendency to worsen (<i>p</i> &#x3c; 0.001). Moreover, HA-AKI incidence (adjusted odds ratio [OR], 10.26; 95% confidence interval (CI), 8.27–12.74; <i>p</i> &#x3c; 0.001), and nephrotoxic drugs exposure (adjusted OR, 1.76; 95% CI, 1.63–1.91; <i>p</i> &#x3c; 0.001) had an association with an increased in-hospital mortality risk. <b><i>Conclusion:</i></b> AKI incidence was high among hospitalized older patients. Older patients with HA-AKI had worse in-hospital outcomes and higher resource utilization. Nephrotoxic drug exposure and HA-AKI incidence were associated with an increased in-hospital mortality risk.

Background: Black individuals have a higher lifetime risk of acute kidney injury (AKI) and chronic kidney disease than whites. Vancomycin has a potential for nephrotoxicity. The objective of this study was to determine whether the incidence of AKI among patients being treated with vancomycin differs by race. Methods: Retrospective study of adult (3 ≥18 years) inpatients who were on vancomycin for 348 hours between January 2012 and December 2014. Data on demographics, comorbid conditions, clinical characteristics, vancomycin dose, duration, and nephrotoxic drugs were collected. Patients with a creatinine clearance <30 mL/min or undergoing dialysis were excluded. Results: We identified 1130 patients during the study period; 48.1% (544) were black. The overall incidence of AKI was 8.2% (10.1% blacks, 6.5% whites; P = .03). Independent predictors of AKI included black race ( P = .011); higher Charlson score ( P = .006); higher body mass index (BMI; P = .002); higher vancomycin trough level ( P < .0001); and sepsis/systemic inflammatory response syndrome (<.0001), pneumonia ( P = .001) or gastrointestinal/genitourinary ( P = .025) as the source of infection. Conclusion: The incidence of vancomycin-related AKI was higher in blacks, independent of other risk factors. Based on our study, vancomycin trough levels and renal function need to be closely monitored in blacks.

Abstract Introduction The effect of valve type on outcomes in transfemoral transcatheter aortic valve replacement (TF-TAVR) has recently been subject of debate. We investigate outcomes of patients treated with balloon-expanding (BE) vs. self-expanding (SE) valves in in a cohort of all these procedures performed in Germany in 2018. Methods All patients receiving TF-TAVR with either BE (N = 9,882) or SE (N = 7,413) valves in Germany in 2018 were identified. In-hospital outcomes were analyzed for the endpoints in-hospital mortality, major bleeding, stroke, acute kidney injury, postoperative delirium, permanent pacemaker implantation, mechanical ventilation > 48 h, length of hospital stay, and reimbursement. Since patients were not randomized to the two treatment options, logistic or linear regression models were used with 22 baseline patient characteristics and center-specific variables as potential confounders. As a sensitivity analysis, the same confounding factors were taken into account using the propensity score methods (inverse probability of treatment weighting). Results Baseline characteristics differed substantially, with higher EuroSCORE (p < 0.001), age (p < 0.001) and rate of female sex (p < 0.001) in SE treated patients. After risk adjustment, no marked differences in outcomes were found for in-hospital mortality [risk adjusted odds ratio (aOR) for SE instead of BE 0.94 (96% CI 0.76;1.17), p = 0.617] major bleeding [aOR 0.91 (0.73;1.14), p = 0.400], stroke [aOR 1.13 (0.88;1.46), p = 0.347], acute kidney injury [OR 0.97 (0.85;1.10), p = 0.621], postoperative delirium [aOR 1.09 (0.96;1.24), p = 0.184], mechanical ventilation > 48 h [aOR 0.98 (0.77;1.25), p = 0.893], length of hospital stay (risk adjusted difference in days of hospitalization (SE instead of BE): − 0.05 [− 0.34;0.25], p = 0.762) and reimbursement [risk adjusted difference in reimbursement (SE instead of BE): − €72 (− €291;€147), p = 0.519)] There is, however, an increased risk of PPI for SE valves (aOR 1.27 [1.15;1.41], p < 0.001). Similar results were found after application of propensity score adjustment. Conclusions We find broadly equivalent outcomes in contemporary TF-TAVR procedures, regardless of the valve type used. Incidence of major complications is very low for both types of valve.

Abstract Background：Improving the diagnosis and treatment of acute kidney injury (AKI) in local hospitals is of great significance in developing countries. The aim of the present survey was to describe the characteristics of AKI in local hospitals at different economic levels and in different regions in mainland China. Methods：We used the database of a nation-wide survey on AKI in mainland China and extracted the data from 22 local hospitals. These hospitals were divided into three groups based on the local per capita gross domestic product (pcGDP) levels. We also divided the hospitals by geographic regions into Northwest China, North China, South China, and Southwest China. Using this data, we analyzed all characteristics associated with AKI. Results: 1,942 patients were diagnosed with AKI in the 22 local hospitals between January and July 2013, with a detection rate of 1.66%. There were significant differences in the detection rates and the classification of AKI across regions with different economic levels or geographic locations. The proportion of patients who had not been recognized with AKI on time, or with unclassifed AKI was higher in local hospitals from regions with lowest and moderate pcGDP levels than that in regions with the highest pcGDP levels. Renal hypoperfusion, drug factors and associated with other serious diseases were the most common causal factors of AKI in all regions. Northwest and Southwest regions had higher proportion of patients with potential nephrotoxic drugs use. The Southwest region had the most patients with environmental toxin-induced AKI compared to other regions. AKI caused by sepsis or surgical factors was more common in South China. The all-cause in-hospital mortality was 10.5%. Advanced age, male gender, staying in ICU, higher AKI stages, using nephrotoxic drugs, being with other critical illness, and delayed recognition were associated with increased in-hospital mortality, while in hospitals from South China or from regions with the highest pcGDP levels were associated with decreased in-hospital mortality.Conclusions: The detection rate of AKI in local hospitals in China is significantly lower than that in provincial hospitals. The etiology of AKI varies across different geographic regions and the level of economic development is closely related to the diagnosis of AKI in local hospitals.

Abstract Background Acute kidney injury (AKI) is frequently present in patients admitted for acute heart failure (AHF). Several studies have evaluated the mortality risk and have concluded poor prognosis in any patient with AKI admitted for AHF. For the most part, the additional morbidity and mortality burden in AHF patients with AKI has been attributed to the concomitant comorbidities, and/or interventions. Purpose We sought to determine the impact of acute kidney injury (AKI) on in-hospital outcomes in patients presenting with acute heart failure (AHF). We identified isolated AKI patients after excluding other concomitant diagnoses and procedures, which may contribute to an increased risk of mortality and morbidity. Methods Data from the National Inpatient Sample (2012- 14) were used to identify patients with the principal diagnosis of AHF and the concomitant secondary diagnosis of AKI. Propensity score matching was performed on 30 baseline variables to identify a matched cohort. The outcome of interest was in-hospital mortality. We further evaluated in-hospital procedures and complications. Results Of 1,470,450 patients admitted with AHF, 24.3% had AKI. After propensity matching a matched cohort of 356,940 patients was identified. In this matched group, the AKI group had significantly higher in-hospital mortality (3.8% vs 1.7%, p&lt;0.001). Complications such as sepsis and cardiac arrest were higher in the AKI group. Similarly, in-hospital procedures including CABG, mechanical ventilation and IABP were performed more in the AKI group. AHF patients with AKI had longer in-hospital stay of ∼1.7 days. Conclusions In a propensity score-matched cohort of AHF with and without AKI, the risk of in-hospital mortality was &gt;2-fold in the AKI group. Healthcare utilization and burden of complications were higher in the AKI group. Funding Acknowledgement Type of funding source: None

Abstract Background and Aims Impaired renal function is a common finding in patients with cardiac diseases and confers an adverse prognosis in this population. To evaluate the incidence, phenotypes and prognostic value of cardiorenal interrelations in patients with acute decompensated heart failure (ADHF) and non-ST-elevation acute coronary syndrome (NSTE-ACS). Method we examined 278 patients with ADHF (85.3% had anamnesis of symptomatic HF with frequent hospitalizations, 20.1% had ejection fraction &lt;35%) and 288 with NSTE-ACS (64.9% developed myocardial infarction (MI)). In ADHF group in comparison with NSTE-ACS the patients were younger (69.7±10.2 vs 72±12.1 years, p&lt;0.01), there were more males (55.4 vs 36.5%, p&lt;0.001), smokers and alcohol abusers (47.8 and 30.6% vs 8 and 5.6%, p&lt;0.001). The comorbidities were more typical for ADHF group: atrial fibrillation 46 vs 24% (p&lt;0.001), obesity 55.8 vs 30.9% (p&lt;0.001), anemia 40.6 vs 25.3% (p&lt;0.001), diabetes mellitus 33.1 vs 23.3% (p&lt;0.01). Chronic kidney disease (CKD) and acute kidney injury (AKI) were diagnosed according to KDIGO 2012 Guidelines. AKI phenotypes were identified depending on time of development (community- or hospital-acquired), persistency (transient or persistent), history of CKD (AKI de novo or AKI on CKD). Results Incidence of CKD in patients with ADHF and NSTE-ACS was 45 and 46.5%, CKD was first diagnosed on admission in 57.6 and 64.2% of patients respectively. In 7.6% cases of ADHF and 14.2% of NSTE-ACS groups the duration of impaired kidney function was unknown. No associations of existing CKD and in-hospital mortality were detected. Incidence of AKI in ADHF and NSTE-ACS groups was 43.5 and 37.2%. The hospital-acquired AKI, AKI on CKD and persistent AKI were found in 52.9, 47.9 and 46.3% of ADHF patients, and in 57.9, 58.9 and 50.5% in NSTE-ACS group respectively. In-hospital mortality was higher in patients with AKI in ADHF and NSTE-ACS groups (12.4 vs 5%, p&lt;0.01 and 17.8 vs 3.3%, p&lt;0.001). Mortality in patients with ADHF and hospital-acquired persistent AKI de novo and community-acquired persistent AKI on CKD was 41 and 29%, and in community-acquired transient AKI on CKD in the NSTE-ACS group – 29%. Conclusion Different cardiorenal interrelations were revealed in 75.2% of patients with ADHF and in 61.8% with NSTE-ACS. In patients with acute cardiac diseases high in-hospital mortality is tightly associated with phenotypes of hospital-acquired persistent AKI de novo and community-acquired persistent AKI on CKD in ADHF, and in community-acquired transient AKI on CKD in the NSTE-ACS.

Abstract Background The epidemic of COVID-19 presents a special threat to older adults. However, information on kidney damage in older patients with COVID-19 is limited. Acute kidney injury (AKI) is common in hospitalized adults and associated with poor prognosis. We sought to explore the association between AKI and mortality in older patients with COVID-19. Methods We conducted a retrospective, observational cohort study in a large tertiary care university hospital in Wuhan, China. All consecutive inpatients older than 65 years with COVID-19 were enrolled in this cohort. Demographic data, laboratory values, comorbidities, treatments, and clinical outcomes were all collected. Data were compared between patients with AKI and without AKI. The association between AKI and mortality was analyzed. Results Of 1764 in-hospital patients, 882 older adult cases were included in this cohort. The median age was 71 years (interquartile range: 68–77), 440 (49.9%) were men. The most presented comorbidity was cardiovascular diseases (58.2%), followed by diabetes (31.4%). Of 882 older patients, 115 (13%) developed AKI and 128 (14.5%) died. Patients with AKI had higher mortality than those without AKI (68 [59.1%] vs 60 [7.8%]; p &lt; .001). Multivariable Cox regression analysis showed that increasing odds of in-hospital mortality are associated with higher interleukin-6 on admission, myocardial injury, and AKI. Conclusions Acute kidney injury is not an uncommon complication in older patients with COVID-19 but is associated with a high risk of death. Physicians should be aware of the risk of AKI in older patients with COVID-19.

Contrast-induced AKI (CI-AKI) has been one of the leading causes for hospital-acquired AKI and is associated with independent risk for adverse clinical outcomes including morbidity and mortality. The aim of this review is to provide a brief summary of the studies that focus on nonpharmacological strategies to prevent CI-AKI, including routine identification of at-risk patients, use of appropriate hydration regimens, withdrawal of nephrotoxic drugs, selection of low-osmolar contrast media or isoosmolar contrast media, and using the minimum volume of contrast media as possible. There is no need to schedule dialysis in relation to injection of contrast media or injection of contrast agent in relation to dialysis program. Hemodialysis cannot protect the poorly functioning kidney against CI-AKI.
