Abstract Background Adenovirus gastroenteritis is a common cause of diarrhea and vomiting in infants, resulting in prerenal acute kidney injury (AKI). However, postrenal AKI due to urinary stones associated with adenovirus gastroenteritis is extremely rare. Here, we describe postrenal AKI due to obstructive ammonium acid urate stones associated with adenovirus gastroenteritis. Case presentation A previously healthy 6-month-old boy had an 11-day history of severe diarrhea and a 5-day history of vomiting. His stool was positive for adenovirus antigens. We initiated fluid replacement therapy. On the second hospital day, he suddenly developed anuria. Abdominal computed tomography revealed bilateral hydronephrosis, left ureteral stones, and right bladder ureteral junction stones. Laboratory data showed that the creatinine level increased to 1.00 mg/dL. We diagnosed postrenal AKI due to obstructive bilateral urinary stones. Urination with stable urine volume resumed spontaneously after hydration. A few stones were found in the urine, which consisted of ammonium acid urate (> 98%). The serum creatinine level improved to 0.25 mg/dL. He was discharged nine days after admission. Conclusions We suggest that adenovirus gastroenteritis be considered in pediatric patients with postrenal AKI due to urinary stones.

Background. The risk factors for acute kidney injury (AKI) development in patients with diabetes hospitalized for COVID-19 have not been fully studied yet. In this study, we aimed to estimate the rate of AKI among the hospitalized population with COVID-19 and to identify the risk factors associated with AKI among patients with diabetes. Material and Methods. This retrospective cohort study included 254 patients (127 with diabetes and 127 without diabetes) who were admitted for COVID-19 to a tertiary hospital in Tehran, Iran, between February and May 2020. Clinical characteristics and outcomes, radiological findings, and laboratory data, including data on AKI, hematuria, and proteinuria were recorded and analyzed. Results. Of 254 patients, 142 (55.9%) were male and the mean (± SD) age was 65.7 years (±12.5). In total, 58 patients (22.8%) developed AKI during hospitalization, of whom 36 patients had diabetes ( p = 0.04 ); most patients (74.1%) had stage 1 or 2 AKI. Also, 8 patients (13.8%) required renal replacement therapy (RRT) after developing AKI. Regardless of diabetes status, patients who developed AKI had significantly higher mortality rates compared with patients who did not develop AKI ( p = 0.02 ). Hematuria and proteinuria were observed in 38.1% and 55% of patients, respectively. Multivariate analysis showed that invasive mechanical ventilation, proteinuria, HBA1c level, history of cardiovascular disease, and use of statins were independent risk factors for AKI development in patients with diabetes. Conclusion. Results of this study showed that AKI develops in a considerable percentage of patients with COVID-19, especially in those with diabetes, and is significantly associated with mortality.

Summary Ammonium acid urate (AAU) crystals are rare in industrialized countries. Furthermore, the number of children with diabetic ketoacidosis (DKA) who develop severe acute kidney injury (AKI) after hospitalization is small. We encountered two patients with AKI caused by AAU crystals during the recovery phase of DKA upon admission. They were diagnosed with severe DKA and hyperuricemia. Their urine volume decreased and AKI developed several days after hospitalization; however, acidosis improved in both patients. Urine sediment analysis revealed AAU crystals. They were treated with urine alkalization and diuretics. Excretion of ammonia in the urine and urine pH levels increased after treatment of DKA, which resulted in the formation of AAU crystals. In patients with severe DKA, the urine and urine sediment should be carefully examined as AAU can form in the recovery phase of DKA. Learning points Ammonium acid urate crystals could be formed in the recovery phase of diabetic ketoacidosis. Diabetic ketoacidosis patients may develop acute kidney injury caused by ammonium acid urate crystals. Urine and urine sediment should be carefully checked in patients with severe DKA who present with hyperuricemia and volume depletion.

A 66-year-old women with no history of renal disease was admitted due to a coma and acute kidney injury with a serum creatinine level of 7.44 mg/dL which were ascribed to valacyclovir neurotoxicity and nephrotoxicity, respectively. She had received valacyclovir at a standard dosage for the treatment of herpes zoster and was finally discharged, having fully returned to her normal baseline mental status with a recovered serum creatinine level of 0.68 mg/dL. We feel that awareness of this pathology remains a challenge for physicians and therefore strongly recommend the further accumulation of experiences similar to our own. Our experience underscores the pitfalls of administering valacyclovir to elderly patients who barely appear to have a favorable renal function. Several concerns regarding the therapeutic management, including blood purification strategies, that emerged in this case are also discussed.

Abstract Background and Aims Hemophagocytic lymphohistiocytosis (HLH) is a syndrome characterized by overproduction of proinflammatory cytokines and hemophagocytosis. Acute kidney injury (AKI) is the most common complication of HLH in the kidney, which is a strong predictor of poor prognosis. In this retrospective study, we aimed to find the risk factors of AKI in patients with HLH. Method We screened all adult patients with HLH admitted to West China Hospital of Sichuan University from January 2009 to June 2019. Patients in this study were secondary HLH according to the HLH diagnostic criteria revised by the Histocyte Society in 2004. Patients with HLH were excluded from the study if they had a functioning kidney transplant, received renal replacement therapy (RRT) in the past month, suffered from end-stage renal disease (ESRD), or had the renal malignant tumor. We collected basic information, clinical manifestations, and laboratory data of patients from electronic medical records. Results A total of 600 patients with confirmed diagnosis of secondary HLH are included in our analysis. There are 199(33.2%)HLH-induced AKI patients, among whom 37.2%, 32.7%, and 30.2% are classified as AKI I, II, and III, respectively, according to the 2012 KDIGO (Kidney Disease: Improving Global Outcomes) guideline. Overall hospital mortality is 176(29.3%), and the number of deaths in patients with AKI was much higher than that in patients without AKI (53.3% versus 17.5%, P < 0.001). The risk factors of AKI in patients with HLH were hyperphosphatemia (P<0.001, OR 5.448, 95%CI 2.951-10.059) , vasopressor(P<0.001, OR 3.485, 95%CI 2.114-5.746), heart failure (P=0.044, 0R 2.336, 95%CI 1.022-5.340), gastrointestinal symptoms (P=0.043, OR 1.877, 95%CI 1.021-3.453), increased heart rate (P=0.005, OR 1.017, 95%CI 1.005-1.029), elevated total bilirubin level(P<0.001, OR 1.004, 95%CI 1.002-1.007), and hypoproteinemia (P=0.034, OR 0.939, 95%CI 0.886-0.995). Conclusion The incidence of AKI was higher in patients with HLH, and the risk of death was significantly higher in HLH patients with AKI. A variety of risk factors are related to the occurrence of HLH-induced AKI. Identifying and correcting them early in clinical diagnosis and treatment may reduce the incidence of AKI in patients with HLH and improve the prognosis of them.

Background: The baseline creatinine level is central in the KDIGO criteria of acute kidney injury (AKI), but baseline creatinine is often inconsistently defined or unavailable in AKI research. We examined the rate, characteristics, and 30-day mortality of AKI in five AKI cohorts created using different definitions of baseline creatinine. Methods: This nationwide cohort study included all individuals aged ≥18 in Denmark with a creatinine measurement in year 2017. Applying the KDIGO criteria, we created four AKI cohorts using four different baseline definitions (most recent, mean, or median value of outpatient creatinine 365-8 days before, or median value 90-8 days before if available otherwise median value 365-91 days before) and one AKI cohort not using a baseline value. AKI rate and the distribution of age, sex, baseline creatinine, and comorbidity was described for each AKI cohort, and the 30-day all-cause mortality was estimated using the Kaplan-Meier method. Results: The study included 2,095,850 adults with at least one creatinine measurement in 2017. The four different baseline definitions identified between 61,189 and 62,597 AKI episodes. The AKI rate in these four cohorts was 13-14 per 1,000 person-years, and 30-day all-cause mortality was 17-18%. The cohort created without using a baseline creatinine included 37,659 AKI episodes, corresponding to an AKI rate of 8.2 per 1,000 person-years, and a 30-day mortality of 23%. All five cohorts were similar regarding age, sex, and comorbidity. Conclusions: In a population-based setting with available outpatient baseline creatinine, different baseline creatinine definitions revealed comparable AKI cohorts, while the lack of a baseline creatinine when defining AKI led to a smaller AKI cohort with a higher mortality. These findings underscore the importance of availability and consistent use of an outpatient baseline creatinine, in particular in studies of community-acquired AKI.

AKI is a syndrome consisting of several clinical conditions, due to sudden kidney dysfunction. Sepsis and septic shock are the causes of AKI and are known as Sepsis-Associated AKI (SA-AKI) and accounted for more than 50% of cases of AKI in the ICU, with poor prognosis. Acute Kidney Injury (AKI) is characterized by a sudden decline in kidney function for several hours/day, which results in the accumulation of creatinine, urea and other waste products. The most recent definition was formulated in the Kidney Disease consensus: Improving Global Outcome (KDIGO), published in 2012, where the AKI was established if the patient’s current clinical manifestation met several criteria: an increase in serum creatinine levels ≥0.3 mg/dL (26.5 μmol/L) within 48 hours, an increase in serum creatinine for at least 1.5 times the baseline value within the previous 7 days; or urine volume ≤ 0.5 ml/kg body weight for 6 hours. The AKI pathophysiology includes ischemic vasodilation, endothelial leakage, necrosis in nephrons and microtrombus in capillaries. The management of sepsis associated with AKI consisted of fluid therapy, vasopressors, antibiotics and nephrotoxic substances, Renal Replacement Therapy (RRT) and diuretics. In the analysis of the BEST Kidney trial subgroup, the likelihood of hospital death was 50% higher in AKI sepsis compared to non-sepsis AKI. Understanding of sepsis and endotoxins that can cause SA-AKI is not yet fully known. Some evidence suggests that renal microcirculation hypoperfusion, lack of energy for cells, mitochondrial dysfunction, endothelial injury and cycle cell arrest can cause SA-AKI. Rapid identification of SA-AKI events, antibiotics and appropriate fluid therapy are crucial in the management of SA-AKI.

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.

Non-Hodgkin’s lymphoma is reportedly common in Africa; however, there is limited data on renal involvement. Acute kidney injury only at presentation is rare for lymphoproliferative malignancies. A 7-year old presented to our facility with a 2-week history of progressive abdominal distension and pain, examination revealed anasarca and hypertension. On further evaluation, there were bilateral nephromegaly, acute kidney injury (AKI) and cytomorphological findings suggestive of lymphoma. Patient management was mostly supportive, and evolution was unfavourable leading to his demise. We discuss diagnostic and therapeutic challenges due to unavailability of state-of-the-art facilities in resource-constrained settings.

Abstract Background and Aims Acute kidney injury (AKI) is increasingly prevalent and it is associated to increased hospital stay and costs, higher risk of developing a chronic kidney disease, and also major morbidity and mortality. Prediction tools may identify patients at high risk of AKI, allowing early intervention. Nephrocheck quantifies biomarkers of AKI (TIMP-2 and IGFBP-7), providing results within 20 minutes. This may allow stratification of the risk of developing an AKI in the next 12 hours in critically cardiovascular or respiratory ill patients and therefore implement preventive measures. We aimed to assess Nephrocheck performance to predict AKI development within 12 hours to 5 days in incident Emergency Room (ER) patients. Method Prospective observational study of 52 incident ER patients. Data were collected from April 2017 to November 2018. Inclusion criteria: sepsis of any origin, or cardiopulmonary insufficiency without AKI at baseline. Nephrochek was performed at baseline, patients were stratified into low (Nephrocheck test &lt; 0.3), moderate (Nephrocheck between 0.3-2) and high risk (Nephrocheck &gt;2) of AKI and occurrence of AKI was assessed (diagnosed as an increase of 0.3 mg/dl of serum creatinine) at 12, 24, 48 h and 5 days. Results Mean age as 70±13 years, 22/52 (43%) were women, risk factors included hypertension (54%), DM (29%), Cirrhosis: 2/52 (4%), heat failure (27%), prior CKD (12%), nephrotoxic use (38%). 18/52 (35%) of patients were Nephrocheck low risk, 21/52 (40%) were intermediate risk and 13/52 (25%) were high risk. AKI developed in 7/18 (39%), 3/21 (14%) and 3/13 (23%) of low, intermediate and high risk, respectively. When comparing patients who developed AKI with those who did not, those who developed AKI had been exposed more frequently to nephrotoxins and had lower urinary osmolarity and higher MAP (Table 1). However, a high risk Nephrocheck score identified patients with significantly higher urine osmolality (672±139 vs 387±172 mOsm/L, P=0.005) and lower MAP (76.7 ± 18.4 vs 101.62±22.7 mmHg; P=0.002). Conclusion LIMITATIONS: knowledge of Nephrocheck results may have changed patient care. CONCLUSIONS: A high risk Nephrocheck score was not associated with a higher risk of AKI in a ER setting. More nephrotoxins were used in the AKI group. Presumabily, these were discontinued in the ER, thus lowering AKI risk. By contrast, a past history of nephrotoxin use and lower urine osmolarity were associated with a higher incidence of AKI.
