Abstract Background and Aims Acute Kidney Injury (AKI) is an important determinant of outcome in hospitalized patients. Further, there is a risk for development of Chronic Kidney Disease (CKD) in the future. Though the long-term impact of AKI has been studied in developed countries, there is a paucity of data in this area from the Indian subcontinent. This single-centre study aimed to assess the pattern, clinical spectrum, short-term and long-term outcomes of AKI. Method In this prospective observational cohort study, detailed demographic and clinical data at presentation, during hospital stay and follow-up at 1, 3, 6 and 12 months after discharge were obtained prospectively for a cohort of patients with AKI. Both community (CAAKI) and hospital acquired AKI (HAAKI) were included. Patient with pre-existing CKD were excluded. Outcome variables examined were in-hospital mortality, renal function at discharge and on follow-up after discharge from hospital. Results In our study cohort with 476 patients, majority of the cases were CAAKI (395, 83%). The mean age at presentation was 44.8 ± 18.7 years. Medical causes (84%) contributed to the majority of AKI while the remaining were due to surgical (10%) and obstetrical (6%) causes. Sepsis (176/476; 36.9%) was the most common cause of AKI. The most common source for sepsis was respiratory (41%) followed by urological source (18.7%). The in-hospital mortality rate for patients with AKI was 38%. Age >60 years (HR = 1.51; 95% CI, 1.11 – 2.07), oliguria (HR = 1.48; 95% CI, 1.05 – 2.10), need for ventilator (HR = 2.45; 95% CI, 1.36 – 4.41) and/or inotropes (HR = 14.4; 95% CI, 6.28 – 33.05) were predictors of mortality. At discharge, 146 (30.7%) patients had complete renal recovery, while 149 (31.3%) had partial renal recovery. Oliguria (p < 0.001), hypoalbuminemia (p = 0.001) and need for renal replacement therapy (RRT) (p = 0.01) were significantly associated with partial recovery. Of the 295 patients on follow-up at discharge, 211 (71.5%) patients had normal renal function, 4 (1.4%) died and 33 (11.2%) were lost to follow up; 47(15.9%) patients developed CKD of which 6 (2%) were dialysis dependent. Elderly patients, higher AKIN stage with oliguria and those requiring RRT were more likely to develop CKD. Among these, the need for in-hospital RRT was the single most important factor predicting the risk of CKD (OR 1.77, 95% CI, 1.12-2.78). Conclusion In conclusion, our data shows that AKI in hospitalized patients still has high mortality in emerging countries like India. Though a fairly good percentage of cases recovered, there is a definite risk of CKD development, especially in patients who required RRT during hospitalization.

Abstract Background Acute kidney injury (AKI) is common in patients in the intensive care unit (ICU) and may be present on admission or develop during ICU stay. Our objectives were (a) to identify factors independently associated with the development of new AKI during early stay in the ICU and (b) to determine the risk factors for non-recovery of AKI. Methods We retrospectively analysed prospectively collected data of patients admitted to a multi-disciplinary ICU in a single tertiary care centre in the UK between January 2014 and December 2016. We identified all patients without AKI or end-stage renal failure on admission to the ICU and compared the outcome and characteristics of patients who developed AKI according to KDIGO criteria after 24 h in the ICU with those who did not develop AKI in the first 7 days in the ICU. Multivariable logistic regression was applied to identify factors associated with the development of new AKI during the 24–72-h period after admission. Among the patients with new AKI, we identified those with full, partial or no renal recovery and assessed factors associated with non-recovery. Results Among 2525 patients without AKI on admission, the incidence of early ICU-acquired AKI was 33.2% (AKI I 41.2%, AKI II 35%, AKI III 23.4%). Body mass index, Sequential Organ Failure Assessment score on admission, chronic kidney disease (CKD) and cumulative fluid balance (FB) were independently associated with the new development of AKI. By day 7, 69% had fully recovered renal function, 8% had partial recovery and 23% had no renal recovery. Hospital mortality was significantly higher in those without renal recovery. Mechanical ventilation, diuretic use, AKI stage III, CKD, net FB on first day of AKI and cumulative FB 48 h later were independently associated with non-recovery with cumulative fluid balance having a U-shape association. Conclusions Early development of AKI in the ICU is common and mortality is highest in patients who do not recover renal function. Extreme negative and positive FB were strong risk factors for AKI non-recovery.

Background. Severe acute kidney injury (AKI) among hospitalized patients often necessitates initiation of short-term dialysis. Little is known about the long-term outcome of those who recover to normal renal function. The aim of this study was to determine the long-term renal outcome of patients experiencing AKI requiring dialysis secondary to hypoperfusion injury and/or sepsis who recovered to apparently normal renal function. Methods. All adult patients with AKI requiring dialysis in our centre between 1 January 1980 and 31 December 2010 were identified. We included patients who had estimated glomerular filtration rate (eGFR) >60 mL/min/1.73 m2 12 months or later after the episode of AKI. Patients were followed up until 3 March 2015. The primary outcome was time to chronic kidney disease (CKD) (defined as eGFR persistently <60 mL/min/1.73 m2) from first dialysis for AKI. Results. Among 2922 patients with a single episode of dialysis-requiring AKI, 396 patients met the study inclusion criteria. The mean age was 49.8 (standard deviation 16.5) years and median follow-up was 7.9 [interquartile range (IQR) 4.8–12.7] years. Thirty-five (8.8%) of the patients ultimately developed CKD after a median of 5.3 (IQR 2.8–8.0) years from first dialysis for AKI giving an incidence rate of 1 per 100 person-years. Increasing age, diabetes and vascular disease were associated with higher risk of progression to CKD [adjusted hazard ratios (95% confidence interval): 1.06 (1.03, 1.09), 3.05 (1.41, 6.57) and 3.56 (1.80, 7.03), respectively]. Conclusions. Recovery from AKI necessitating in-hospital dialysis was associated with a very low risk of progression to CKD. Most of the patients who progressed to CKD had concurrent medical conditions meriting monitoring of renal function. Therefore, it seems unlikely that regular follow-up of renal function is beneficial in patients who recover to eGFR >60 mL/min/1.73 m2 by 12 months after an episode of AKI.

Background. The real impact of septic shock-associated acute kidney injury (AKI) on the long-term renal outcome is still debated, and little is known about AKI-burn patients. In a cohort of burn survivors treated by continuous renal replacement therapy (CRRT) and sorbent technology (CPFA-CRRT), we investigated the long-term outcome of glomerular and tubular function. Methods. Out of 211 burn patients undergoing CRRT from 2001 to 2017, 45 survived, 40 completed the clinical follow-up (cumulative observation period 4067 months, median 84 months, IR 44-173), and 30 were alive on 31 December 2020. Besides creatinine and urine albumin, in the 19 patients treated with CPFA-CRRT, we determined the normalized GFR by 99mTc-DTPA (NRI-GFR) and studied glomerular and tubular urine protein markers. Results. At the follow-up endpoint, the median plasma creatinine and urine albumin were 0.99 (0.72–1.19) and 0.0 mg/dL (0.0–0.0), respectively. NRI-GFR was 103.0 mL/min (93.4–115). Four patients were diabetic, and 22/30 presented at least one risk factor for chronic disease (hypertension, dyslipidemia, and overweight). Proteinuria decreased over time, from 0.47 g/day (0.42–0.52) at 6 months to 0.134 g/day (0.09–0.17) at follow-up endpoint. Proteinuria positively correlated with the peak of plasma creatinine (r 0.6953, p 0.006) and the number of CRRT days (r 0.5650, p 0.035) during AKI course, and negatively with NRI–GFR (r −0.5545, p 0.049). In seven patients, urine protein profile showed a significant increase of glomerular marker albumin and glomerular/tubular index. Conclusions. Burn patients who experienced septic shock and AKI treated with CRRT had a long-term expectation of preserved renal function. However, these patients were more predisposed to microalbuminuria, diabetes, and the presence of risk factors for intercurrent comorbidities and chronic renal disease.

Abstract Background and Aims Proteinuria, hematuria and acute kidney injury (AKI) are frequently observed in hospitalized patients with COVID-19. However, few data are available on these parameters after hospital discharge. Method This retrospective, observational and monocentric study included 153 hospitalized patients, in whom urine total proteinuria and α1-microglobulin (a marker of tubular injury) were measured. Thirty patients died. Among the 123 survivors, follow-up urine and creatinine analyses were available for 72 patients (after a median of 51 [19;93] days following hospital discharge). Results The median proteinuria at hospitalization and follow-up (n=72) was 419 [239; 748] and 79 [47; 129] mg/g, respectively (p&lt;0.0001). The median concentrations of urinary α1-microglobulin (n=66) were 50 [25; 81] and 8 [0; 19] mg/g, respectively (p&lt;0.0001). Estimating glomerular filtration rate (eGFR) was lower during the hospitalization compared to the follow-up: 81 [62; 92] versus 87 [66; 98] mL/min/1.73m² (p=0.0222). At follow-up, a decreased renal function was observed in 10/72 (14%) of patients, with 50% of them presenting decreased renal function before COVID-19 hospitalization and others developing severe AKI and/or proteinuria during hospitalization. Conclusion In most hospitalized patients with COVID-19, proteinuria and eGFR significantly improved after hospital discharge. Only patients who developed severe AKI and/or heavy proteinuria will require a specific follow-up by nephrologists.

Abstract Background Nephrotoxicity is a common adverse effect of polymyxin B (PMB) with reported acute kidney injury (AKI) rates of 20% to &gt;60%. Data on PMB dosing to optimize efficacy while minimizing toxicity are limited. Previous studies suggest higher doses improve outcomes but are also associated with more AKI. Data are needed to evaluate optimal dosing and contributing factors to minimize AKI and to evaluate renal recovery. Methods Retrospective study evaluating PMB in adults at NewYork-Presbyterian Hospital from 2012 to 2016. Patients who received PMB dosed twice daily for ≥2 days were included. Patients on renal replacement therapy within 48 hours prior to PMB or with AKI at time of PMB initiation were excluded. A classification and regression tree (CART) analysis was performed to identify the PMB dose most predictive of AKI which defined the breakpoint for high- vs. low-dose PMB cohorts for all subsequent comparisons. The primary outcome was to determine whether high-dose PMB independently predicted AKI. Secondary outcomes included in-hospital mortality, time to AKI, and recovery of renal function. Results 246 patients were included: majority were male (59%) with median age 41 years. Median PMB dose was 2.9 mg/kg/day or 180 mg/day for a median duration of 10 days. AKI occurred in 64% and 38% had recovery of renal function by hospital discharge. The breakpoint for high-dose PMB determined by CART was 160 mg/day, putting 104 in low-dose and 142 in high-dose groups. High-dose PMB was associated with AKI compared with low-dose PMB on univariable (75% vs.. 49%, P &lt; 0.001) and multivariable (OR 3.43; 95% CI 1.68,6.99; P = 0.001) analyses. Concomitant vancomycin (OR 3.34; 95% CI 1.74,6.41;P &lt; 0.001), history of transplant (OR 4.96; 95% CI 2.14,11.48;P &lt; 0.001), and previous PMB exposure (OR 2.37; 95% CI 1.23,4.57; P = 0.01) were also identified as independent predictors of AKI. No significant differences were found for in-hospital mortality (28% vs. 21%, P = 0.326), renal recovery (37% vs. 41%, P = 0.723), time to AKI (median 5 vs. 6 days, P = 0.125) between groups. Conclusion High-dose PMB (&gt;160 mg/day) was independently associated with AKI as well as concomitant vancomycin, history of transplant, and previous PMB exposure. High-dose PMB did not have a significant impact on in-hospital mortality, recovery of renal function, or time to development of AKI. Disclosures M. Yin, Gilead Sciences: Consultant, Consulting fee.

Abstract Background COVID-19 infection manifests as pneumonia associated with multiple organ failure, and death. Acute kidney injury is a risk factor for mortality. There is limited scientific literature on COVID-19 infection and allergic tubulointerstitial nephritis, its clinical course and short- and long-term prognosis. Method We performed a retrospective study where medical records of 60 patients with histological diagnosis of allergic tubulointerstitial nephritis from January 2009 to November 2020. In these patients, we studied the incidence of COVID-19 infection, clinical characteristics and prognosis from March to the actual date. Results Of 60 patients with allergic tubulointerstitial nephritis, 6 (10%) patients were diagnosed with COVID-19. The first case, an 85-year-old woman with a history of metastatic melanoma treated with nivolumab and allergic tubulointerstitial nephritis by immunobiological agents in 2018, diagnosed with mild COVID-19 infection in April 2020 without deterioration of renal function in controls at 3 and 6 months of follow-up. The second case, a 51-year-old woman with a history of large B-cell lymphoma with plasmacytic differentiation and progression to multiple myeloma of lambda light chains and allergic tubulointerstitial nephritis due to chemotherapy since 2019, admitted for acute pyelonephritis and PRES syndrome secondary to first dose of bortezomib complicated with COVID-19 nosocomial pneumonia and acute pancreatitis treated with corticosteroids and broad spectrum antibiotic therapy; she died of abdominal refractory septic shock. The third patient, a 64-year-old man without prior renal impairment, was admitted for severe COVID-19 pneumonia and acute kidney injury secondary to acute tubulointerstitial nephritis of uncertain etiology that required orotracheal intubation and continuous veno-venous hemodiafiltration for a week who received methylprednisolone in bolus for 3 days and continued treatment with corticosteroid therapy with complete recovery of renal function and improvement in proteinuria at 3 months of follow-up. The fourth patient, an 82-year-old woman with acute kidney injury AKIN 3 secondary to acute allergic tubulointerstitial nephritis related to ciprofloxacin complicated with severe COVID-19 nosocomial pneumonia, who died despite ventilatory support and high-dose steroids therapy and tocilizumab. The fifth patient, a 75-year-old with a history of metastatic lung adenocarcinoma treated with immunobiological agents and allergic tubulointerstitial nephritis in  2018, admitted in march 2020 for mild COVID-19 pneumonia treated with steroids and hydroxychloroquine without deterioration of respiratory and kidney function.  The sixth patient, an 86-years-old man with acute kidney injury AKIN 3 due to acute allergic tubulointerstitial nephritis secondary to proton-binding inhibitors and nosocomial COVID-19 infección with improvement of kidney function with steroids therapy only.  Conclusion Our 6 patients with allergic tubulointerstitial nephritis and COVID-19 infection presented different spectrum of the disease. It seems that nosocomial COVID-19 infection in patients admitted with recent diagnosis of acute allergic tubulointerstitial nephritis presented a worse clinical prognosis compared with long-term diagnosed acute tubulointerstitial nephritis. Further studies with a larger sample size are needed.

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.
