Abstract Background and Aims Recent advances in treatment of cancer lead to improvement in mortality among cancer patients. However, data regarding outcomes of cancer patients with acute kidney injury (AKI) requiring dialysis were scarce. We conducted this study to see the difference in mortality and other outcomes between cancer and non-cancer patients who had AKI requiring dialysis. Method We reviewed medical record of previous 18 months in our institute. Patients with age at least 18 years with acute kidney injury requiring dialysis were included in our study. Primary outcome was mortality at 30 days. Renal recovery and chronic kidney disease (CKD) after AKI events were also recorded. Results A total of 61 patients were included in our study; 28 patients had no cancer and 33 patients had cancer. Of cancer patients, 81.8% had advanced stage cancer. Modality of dialysis was continuous renal replacement therapy in 36.1%. Mortality at day 30 was not significantly different between cancer patients and non-cancer patients (57.6% vs. 53.6%, P = 0.754). Of alive patients, renal recovery among cancer patients and non-cancer patients was also not significantly different (69.2% vs. 50.0%, P = 0.310). CKD after episodes of AKI was also not significantly different between cancer patients and non-cancer patients (42.8% vs. 77.8%, P = 0.302). Conclusion This is the first study to compare mortality between cancer and non-cancer patients who had AKI requiring dialysis. We found no significant difference regard to mortality between AKI patients requiring dialysis with and without cancer. Renal recovery and CKD development were also not significantly different between two groups. More studies in nephro-oncology field are required for better treatment in cancer patients.

e18816 Background: Acute Kidney Injury (AKI) in patients with COVID-19 infection is associated with poor clinical outcomes. We examined outcomes (hemodialysis, mechanical ventilation, ICU admission and death) in cancer patients with normal estimated glomerular filtration rate (eGFR) treated in a tertiary referral center with COVID-19 infection, who developed AKI within 30 days of diagnosis. Methods: All patient data — demographics, labs, comorbidities and outcomes — were aggregated and analyzed in the Syntropy platform, Palantir Foundry (“Foundry”), as part of the Data-Driven Determinants of COVID-19 Oncology Discovery Effort (D3CODE) protocol at MD Anderson. The cohort was defined by the following: (1) positive COVID-19 test; (2) baseline eGFR >60 ml/min/1.73m2most temporally proximal lab results within 30 days prior to the patient’s infection. AKI was defined by an absolute change of creatinine ≥0.3 within 30 days after the positive COVID-19 test. Kaplan-Meier analysis was used for survival estimates at specific time periods and multivariate Cox Proportional cause-specific Hazard model regression to determine hazard ratios with 95% confidence intervals for major outcomes. Results: 635 patients with Covid-19 infection had a baseline eGFR >60 ml/min/1.73m2. Of these patients, 124 (19.5%) developed AKI. Patients with AKI were older, mean age of 61+/-13.2 vs 56.9+/- 14.3 years (p=0.002) and more Hypertensive (69.4% vs 56.4%, p=0.011). AKI patients were more likely to have pneumonia (63.7% vs 37%, p<0.001), cardiac arrhythmias (39.5% vs 20.7%, p<0.001) and myocardial infarction (15.3% vs 8.8%, p=0.046). These patients had more hematologic malignancies (35.1% vs 19%, p=0.005), with no difference between non metastatic vs metastatic disease (p=0.284). There was no significant difference in other comorbidities including smoking, diabetes, hypothyroidism and liver disease. AKI patients were more likely to require dialysis (2.4% vs 0.2%, p=0.025), mechanical ventilation (16.1% vs 1.8%, p<0.001), ICU admission (43.5% vs 11.5%, p<0.001) within 30 days, and had a higher mortality at 90 days of admission (20.2% vs 3.7%, p<0.001). Multivariate Cox Proportional cause-specific Hazard model regression analysis identified history of Diabetes Mellitus (HR 10.8, CI 2.42 - 48.4, p=0.001) as an independent risk factor associated with worse outcomes. Mortality was higher in patients with COVID-19 infection that developed AKI compared with those who did not developed AKI (survival estimate 150 days vs 240 days, p=0.0076). Conclusions: In cancer patients treated at a tertiary cancer center with COVID-19 infection and no history of CKD, the presence of AKI is associated with worse outcomes including higher 90 day mortality, ICU stay and mechanical ventilation. Older age and hypertension are major risk factors, where being diabetic was associated with worse clinical outcomes.

Abstract Background Complications in cancer patients with COVID-19 have not been examined. This analysis aimed to compare characteristics of COVID-19 patients with and without cancer, and assess whether cancer is associated with COVID-19 morbidity or mortality. Methods COVID-19 positive patients with an inpatient or emergency encounter at the Mount Sinai Health System between March 1, 2020 and May 27, 2020 were included, and compared across cancer status on demographics and clinical characteristics. Multivariable logistic regressions were used to model the associations of cancer with sepsis, venous thromboembolism, acute kidney injury, intensive care unit admission, and all-cause mortality. Results There were 5,556 COVID-19 positive patients included; 421 (7.6%) with cancer (325 solid, 96 non-solid). Those with cancer were statistically significantly older, more likely to be non-Hispanic Black and to be admitted to the hospital during their encounter, and had more comorbidities than non-cancer COVID-19 patients. Cancer patients were statistically significantly more likely to develop sepsis (adjusted odds ratio [ORadj]=1.31, 95% confidence interval [CI]=1.06-1.61) and venous thromboembolism (ORadj=1.77, 95% CI = 1.01-3.09); there was no statistically significant difference in acute kidney injury (ORadj=1.10, 95% CI = 0.87-1.39), intensive care unit admissions (ORadj=1.04, 95% CI = 0.80-1.34), or mortality (ORadj=1.02, 95% CI = 0.81-1.29). Conclusions COVID-19 patients with cancer may have a higher risk for adverse outcomes. Although there was no statistically significant difference in mortality, COVID-19 patients with cancer have significantly higher risk of thromboembolism and sepsis. Further research is warranted into the potential effects of cancer treatments on inflammatory and immune responses to COVID-19, and on the efficacy of anticoagulant therapy in these patients.

We aimed to evaluate whether the duration and stage of acute kidney injury (AKI) are associated with the occurrence of chronic kidney disease (CKD) in patients undergoing cardiac or thoracic aortic surgery. A total of 2009 cases were reviewed. The patients with postoperative AKI stage 1 and higher stage were divided into transient (serum creatinine elevation ≤48 h) or persistent (>48 h) AKI, respectively. Estimated glomerular filtration rate (eGFR) values during three years after surgery were collected. Occurrence of new-onset CKD stage 3 or higher or all-cause mortality was determined as the primary outcome. Multivariable Cox regression and Kaplan–Meier survival analysis were performed. The Median follow-up of renal function after surgery was 32 months. The cumulative incidences of our primary outcome at one, two, and three years after surgery were 19.8, 23.7, and 26.1%. There was a graded significant association of AKI with new-onset CKD during three years after surgery, except for transient stage 1 AKI (persistent stage 1: HR 3.11, 95% CI 2.62–4.91; transient higher stage: HR 4.07, 95% CI 2.98–6.11; persistent higher stage: HR 13.36, 95% CI 8.22–18.72). There was a significant difference in survival between transient and persistent AKI at the same stage. During three years after cardiac surgery, there was a significant and graded association between AKI stages and the development of new-onset CKD, except for transient stage 1 AKI. This association was stronger when AKI lasted more than 48 h at the same stage. Both duration and severity of AKI provide prognostic value to predict the development of CKD.

Introduction. Acute kidney injury (AKI) remains a critical issue for cancer patients despite recent treatment improvements. This study aimed to assess the incidence of AKI in cancer patients and its related risk factors. Methods. A Retrospective cohort study was conducted at tertiary hospitals in the period 2016–2018. A data abstraction sheet was used to collect related variables from patients’ records. During admission, the incidence of AKI was assessed using creatinine measurements. RIFLE criteria were used to classify it into five categories of severity: risk, injury, failure, loss, and end-stage renal disease. Results. Using RIFLE (Risk, Injury, Failure, Loss, and End-stage renal disease) criteria, 6.9% of admissions were complicated with AKI. The severity of these fell into the categories of risk, injury, and failure, 3.3%, 1.7%, and 1.9%, respectively. In the multivariate model, the odds for developing AKI was significantly higher for patients with congestive heart failure (AOR = 17.1, 95% CI 1.7–80.1), chronic kidney disease (adjusted OR = 6.8, 95% CI 1.4–32.2 ( P value 0.017)), sepsis (AOR = 4.4, 95% CI 1.9–10.1), hypercalcemia (AOR = 8.4, 95% CI 1.3–46.1), and admission to the ICU (AOR = 5.8, 95% CI 2.1–16.2). In addition, the mortality rate was nearly seven times higher for patients complicated by AKI (relative risk = 7.6, 95% CI 3.2–18.2). Conclusion. AKI was significantly associated with congestive heart failure, chronic kidney disease, sepsis, ICU admission, and hypercalcemia in cancer patients, resulting in poorer outcomes and higher mortality rates. AKI assessment for hospitalized cancer patients should be performed regularly, especially for patients at increased risk.

e17540 Background: Prophylactic percutaneous gastrostomy tube (PEG) insertion reduces toxicity from chemoradiation to the head and neck but is thought to increase long term feeding tube dependence. This study retrospectively examines incidence and risk factors for treatment related complications of oropharynx cancer patients with and without prophylactic PEGs. Methods: Rush University Medical Center oropharynx cancer patients who received definitive chemoradiation treatment between 2007-2018 were included. Classifications were: “therapeutic” PEG (pretreatment for immediate use due to inability to swallow), prophylactic PEG, reactive PEG (patient/physician preference or 10% weight loss from baseline), and no PEG inserted on treatment. We compared patients with reactive or no PEG to (1) patients with prophylactic PEG, and (2) patients with prophylactic PEG and therapeutic PEG. Multivariate linear and logistical regression models were used to test PEG effect on weight loss, hospital admission, and incidence of acute kidney injury (AKI). Models were adjusted for covariates (age, gender, race, HTN, CAD, DM, other comorbidity). Acute kidney injury (AKI) was creatinine 1.5-2x above baseline. Results: In all, 104 patients were included with mean age 60.1 (SD = 8.65) and baseline BMI 29.6 (SD = 5.62). 53.4% (N = 55) had a prophylactic PEG, 38.8% (N = 40) had reactive or no PEG, 7.8% (N = 8) had a therapeutic PEG. 80 (76.9%) were treated with cisplatin. For all patients, analyses showed that reactive PEG or no PEG patients were more likely to develop AKI during treatment compared to patients with a prophylactic PEG (OR:3.2, p = 0.03), and to patients with prophylactic PEG and therapeutic PEG combined (OR:3.5, p = 0.02). There were no statistically significant differences between PEG groups for weight loss and hospital admission rate. In cisplatin treated patients, reactive PEG or no PEG patients were more likely to be admitted to the hospital compared to prophylactic PEG patients (OR:3.8, p = 0.04). Compared to patients with prophylactic and therapeutic PEG combined, however, there was no statistically significant difference. Patients with reactive or no PEG were more likely to have AKI than prophylactic PEG (OR:5.2, p < 0.01), and as compared to patients with therapeutic or prophylactic PEG (OR:4.4, p = 0.02). Conclusions: Reactive PEGs were associated with increased AKI and hospitalizations compared with prophylactic PEG. With a reactive PEG model, patients may need to have routine lab work and monitoring adjusted to reduce treatment complications.

Abstract Background This study aimed to investigate the association of acute kidney injury (AKI) with change in estimated glomerular filtration rate (eGFR) in children with advanced chronic kidney disease (CKD). Methods Single centre, retrospective longitudinal study including all prevalent children aged 1–18 years with nondialysis CKD stages 3–5. Variables associated with CKD were analysed for their potential effect on annualised eGFR change (ΔGFR/year) following multiple regression analysis. Composite end-point including 25% reduction in eGFR or progression to kidney replacement therapy was evaluated. Results Of 147 children, 116 had at least 1-year follow-up in a dedicated CKD clinic with mean age 7.3 ± 4.9 years with 91 (78.4%) and 77 (66.4%) with 2- and 3-year follow-up respectively. Mean eGFR at baseline was 29.8 ± 11.9 ml/min/1.73 m2 with 79 (68%) boys and 82 (71%) with congenital abnormalities of kidneys and urinary tract (CAKUT). Thirty-nine (33.6%) had at least one episode of AKI. Mean ΔGFR/year for all patients was − 1.08 ± 5.64 ml/min/1.73 m2 but reduced significantly from 2.03 ± 5.82 to − 3.99 ± 5.78 ml/min/1.73 m2 from youngest to oldest age tertiles (P < 0.001). There was a significant difference in primary kidney disease (PKD) (77% versus 59%, with CAKUT, P = 0.048) but no difference in AKI incidence (37% versus 31%, P = 0.85) between age tertiles. Multiple regression analysis identified age (β = − 0.53, P < 0.001) and AKI (β = − 3.2, P = 0.001) as independent predictors of ΔGFR/year. 48.7% versus 22.1% with and without AKI reached composite end-point (P = 0.01). Conclusions We report AKI in established CKD as a predictor of accelerated kidney disease progression and highlight this as an additional modifiable risk factor to reduce progression of kidney dysfunction.

The Difference

Background. Renal replacement therapy (RRT), as a cornerstone of supportive treatment, has long been performed in critically ill patients with acute kidney injury (AKI). However, the majority of studies may have neglected the effect of the duration of RRT  on the outcome of AKI patients. This paper is aiming to explore the effect of the long duration of RRT  on the outcome of critically ill patients with AKI. Methods. This retrospective study was conducted by using the Multiparameter Intelligent Monitoring in Intensive Care II (MIMIC-II) database. The primary outcome measure of this study was the mortality at 28 days, 60 days, and 90 days in the long-duration RRT group and the non-long-duration RRT group. The secondary outcomes assessed the difference in clinical outcome in these two groups. Lastly, the effect of the duration of RRT on mortality in AKI patients was determined as the third outcome. Results. We selected 1,020 patients in total who received RRT according to the MIMIC-II database. According to the inclusion and exclusion criteria, we finally selected 506 patients with AKI: 286 AKI patients in the non-long-duration RRT group and 220 in the long-duration RRT group. After 28 days, there was a significant difference in all-cause mortality between the long-duration RRT group and the non-long-duration RRT group ( P = 0.001 ). However, the difference disappeared after 60 days and 90 days ( P = 0.803 and P = 0.925 , respectively). The length of ICU stay, length of hospital stay, and duration of mechanical ventilation were significantly longer in the long-duration RRT group than those in the non-long-duration RRT group. Considering 28-day mortality, the longer duration of RRT was shown to be a protective factor (HR = 0.995, 95% CI 0.993–0.997, P < 0.0001 ), while 60-day and 90-day mortality were not correlated with improved protection. Conclusions. The long duration of RRT can improve the short-term prognosis of AKI patients, but it does not affect the long-term prognosis of these patients. Prognosis is determined by the severity of the illness itself. This suggests that RRT can protect AKI patients through the most critical time; however, the final outcome cannot be altered.

Background. Since the first diagnosed case of infection with the novel coronavirus (SARS-CoV-2), there has been a rapid spread of the disease with an increasing number of cases confirmed every day, as well as a rising death toll. An association has been reported between acute kidney injury (AKI) and mortality in patients infected with SARS-CoV-2. Therefore, our study was conducted to explore possible risk factors of AKI as well as whether AKI was a risk factor for worse outcome, especially mortality among patients with coronavirus disease (COVID-19). Methods. We included all hospital admissions with confirmed or clinically diagnosed COVID-19 from January 29 to February 25, 2020. We collected demographic and epidemiological information, past medical history, symptoms, laboratory tests, treatments, and outcome data from electronic medical records. A total of 492 patients with diagnosed or clinically diagnosed COVID-19 were included in this study. Results. The prevalence rate of AKI was 7.32%. Among the factors associated with AKI, males versus females (aOR 2.73), chronic kidney disease (aOR 42.2), hypertension (aOR 2.82), increased leucocytes (aOR 6.08), and diuretic use (aOR 7.89) were identified as independent risk factors for AKI among patients infected by SARS-CoV-2. There was a significant difference in hospital fees and death in patients with and without AKI ( p < 0.05 ). The mortality rate in patients with AKI was 63.9%. Conclusions. AKI was widespread among patients with COVID-19. The risk factors of AKI in COVID-19 patients included sex, chronic kidney disease, hypertension, infection, and diuretic use. AKI may be associated with a worse outcome, especially mortality in COVID-19 patients.

Peritoneal dialysis (PD) has recently been established as a treatment option for renal replacement therapy (RRT) in patients with acute kidney injury (AKI). Its efficacy in providing fluid and small solute removal has also been demonstrated in clinical trials and is equivalent to hemodialysis (HD). However, effect of RRT modality on renal recovery after AKI remains a controversy. Moreover, the setting of human immunodeficiency virus- (HIV-) infected patients with AKI requiring RRT makes the decision on RRT initiation and modality selection more complicated. The authors report here 2 cases of HIV-infected patients presenting with severe AKI requiring protracted course of acute RRT. PD had been performed uneventfully in both cases for 4–9 months before partial renal recovery occurred. Both patients eventually became dialysis independent but were left in chronic kidney disease (CKD) stage 4. These cases highlight the example of renal recovery even after a prolonged course of dialysis dependence. Thus, PD might be a suitable option for HIV patients with protracted AKI.

<b><i>Introduction:</i></b> In critically ill patients requiring intermittent renal replacement therapy (RRT), the benefits of convective versus diffusive clearance remain uncertain. We conducted a systematic review and meta-analysis to determine the safety, clinical efficacy, and clearance efficiency of hemofiltration (HF) and hemodiafiltration (HDF) compared to hemodialysis (HD) in patients with acute kidney injury (AKI) receiving intermittent RRT. <b><i>Method:</i></b> We searched Medline, Embase, Cochrane Library, and PROSPERO. We included clinical trials and observational studies that reported the use of intermittent HF or HDF in adult patients with AKI. The following outcomes were included: mortality, renal recovery, clearance efficacy, intradialytic hemodynamic stability, circuit loss, and inflammation modulation. <b><i>Results:</i></b> A total of 3,169 studies were retrieved and screened. Four randomized controlled trials and 4 observational studies were included (<i>n</i>: 615 patients). Compared with conventional HD, intermittent convective therapies had no effect on in-hospital mortality (relative risk, 1.23; 95% confidence interval (CI), 0.76–1.99), renal recovery at 30 days (RR, 0.98; 95% CI, 0.82–1.16), time-to-renal recovery (mean difference [MD], 0.77; 95% CI, −6.56 to 8.10), and number of dialysis sessions until renal recovery (MD, −1.34; 95% CI, −3.39 to 0.72). The overall quality of included studies was low, and dialysis parameters were suboptimal for all included studies. <b><i>Conclusion:</i></b> This meta-analysis suggests that there is no significant difference in short-term mortality and renal recovery in patients with severe AKI when treated with intermittent HF or HDF compared to conventional HD. This systematic review emphasizes the need for further trials evaluating optimal convective parameters in AKI patients treated with intermittent dialysis.
