Vancomycin is a first-line agent used in the treatment of methicillin-resistant Staphylococcus aureus ; however, vancomycin is associated with acute kidney injury (AKI). Previous literature demonstrates decreased incidence of AKI using 24-hour area under the concentration-time curve (AUC 24 ) monitoring, but its safety is unknown in obese populations. Patients ≥18 years, with Body Mass Indices (BMI) ≥30 kg/m 2 , admitted between August 2015-July 2017 or October 2017-September 2019, who received vancomycin for ≥72 hours and had level(s) drawn within 96 hours of initiation were included. The primary outcome was incidence of AKI. Secondary outcomes included inpatient mortality rate, median inpatient length of stay, median vancomycin trough concentration, and median vancomycin AUC 24 . AKI was identified using the highest serum creatinine value compared to the value immediately prior to vancomycin initiation based on Kidney Disease Improving Global Outcomes (KDIGO) criteria. Overall, 1024 patients met inclusion criteria, with 142 out of 626 patients in the trough group and 65 out of 398 patients in the AUC 24 group meeting criteria for AKI (22.7% vs. 16.3%, p=0.008). Logistic regression of the data to account for confounding factors maintained significance for the reduction in incidence of AKI with AUC 24 monitoring compared to trough monitoring (p=0.010). Monitoring of vancomycin with AUC 24 was associated with a decreased risk of AKI when compared with trough monitoring in obese patients.

Abstract Background This study analyzed the relationship between vancomycin area under the concentration-time curve (AUC) and acute kidney injury (AKI) reported across recent studies. Methods A systematic review of PubMed, Medline, Scopus, and compiled references was conducted. We included randomized cohort and case-control studies that reported vancomycin AUCs and risk of AKI (from 1990 to 2018). The primary outcome was AKI, defined as an increase in serum creatinine of ≥0.5 mg/L or a 50% increase from baseline on ≥2 consecutive measurements. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Primary analyses compared the impact of AUC cutpoint (greater than ~650 mg × hour/L) and AKI. Additional analysis compared AUC vs trough-guided monitoring on AKI incidence. Results Eight observational studies met inclusion/exclusion criteria with data for 2491 patients. Five studies reported first-24-hour AUCs (AUC0-24) and AKI, 2 studies reported 24- to 48-hour AUCs (AUC24-48) and AKI, and 2 studies reported AKI associated with AUC- vs trough-guided monitoring. AUC less than approximately 650 mg × hour/L was associated with decreased AKI for AUC0-24 (OR, 0.36 [95% CI, .23–.56]) as well as AUC24-48 (OR, 0.45 [95% CI, .27–.75]). AKI associated with the AUC monitoring strategy was significantly lower than trough-guided monitoring (OR, 0.68 [95% CI, .46–.99]). Conclusions AUCs measured in the first or second 24 hours and lower than approximately 650 mg × hour/L may result in a decreased risk of AKI. Vancomycin AUC monitoring strategy may result in less vancomycin-associated AKI. Additional investigations are warranted.

Abstract Background and Aims Urinary microRNA (miRNA)-21 is reported to be a biomarker for detection of acute kidney injury (AKI). Analysis of urinary exsome may serve as a novel diagnostic approach in kidney disease. The aim of this study is to investigate the clinical significance of urinary exosomal miRNA-21 for AKI in patients with scrub typhus. Method In a cross-sectional study, we collected 138 urine samples at the time of admission from 145 patients with scrub typhus. For 25 patients with scrub typhus-associated AKI and 25 age, sex-matched scrub typhus patient without AKI, we measured miRNA-21 in urinary exosomal fraction and compared diagnostic value in predictiong AKI. Results Compared with patients in the non-AKI group, patients in the AKI group were more likely to have one or more comorbidity such as diabetes (50% vs. 5%, P<0.01) and chronic kidney disease (8% vs. 0%, P<0.01). Total leukocyte count were higher in patients with AKI than in those without AKI (10.40 × 103/ mL vs. 6.40 × 103/mL, P<0.01). The levels of urinary miRNA-21 were higher in the AKI group than in the non-AKI group. Urinary exosomal miRNA-21 levels correlated directly with serum neutrophil gelatinase-associated lipocalin values and total leukocyte counts and inversely with estimated glomerular filtration rate. The receiver operator characteristics curve analysis for urinary exosomal miRNA-21 showed good discriminative power for the diagnosis of scrub typhus-associated AKI, with area under the curve value of 0.907. Conclusion Urinary exosomal miRNA-21 could be a surrogate markers for the diagnosis of scrub typhus–associated AKI.

Background Acute kidney injury (AKI) is still diagnosed by measuring the estimated creatinine clearance (eCCl), despite the fact that it may not change until 50% or more of kidney function has been lost. AKI after cardiac surgery is related to prolonged intensive care, decreased quality of life, and increased long term mortality. Neutrophil gelatinase-associated lipocalin (NGAL) represents an early biomarker of AKI, which may be useful for assessing AKI in cardiac patients.Objective To determine the validity of urinary and plasma NGAL as biomarkers for AKI in children after cardiac surgery.Methods Subjects were children who underwent cardiac surgery in Dr. Soetomo Hospital, Surabaya, Indonesia from August 2013 to January 2014. Serial urine and blood samples were analyzed for NGAL before surgery, as well as at 2h, 4h, 12h, and 24h after surgery. The AKI was established based on pRIFLE criteria. Estimated creatinine clearance (eCCl) was calculated from the estimated glomerular filtration rate (eGFR), according to age by the traditional Schwartz formula. Serum creatinine was assayed by the Jaffe method before surgery, as well as at 12h, 24h, 48h, and 72h after surgery.Results Of 20 subjects, 5 developed AKI. Urinary and plasma NGAL increased markedly at 2h postoperatively, as compared to eGFR which showed a rise at 12-48 h after cardiac surgery. Analysis of 2h post-operative urinary NGAL at a cut off value of 11.270ng/mL yielded an area under the curve (AUC) of 1.00 (95%CI 2.63 to 12.13), with sensitivity and specificity of 100% each for AKI. In addition, 2h post-operative plasma NGAL at a cut off value of 8.385 ng/mL yielded an AUC of 1.00 (95%CI 3.71 to 12.15) with sensitivity and specificity of 100% each for AKI.Conclusion Urinary and plasma NGAL are valid as early biomarkers for AKI in children after cardiac surgery.

Abstract Background Skin autofluorescence (SAF) reflects accumulation of advanced glycation end-products (AGEs). The aim of this study was to evaluate predictive usefulness of SAF measurement in prediction of acute kidney injury (AKI) after liver resection. Methods This prospective observational study included 130 patients undergoing liver resection. The primary outcome measure was AKI. SAF was measured preoperatively and expressed in arbitrary units (AU). Results AKI was observed in 32 of 130 patients (24.6%). SAF independently predicted AKI (p = 0.047), along with extent of resection (p = 0.019) and operative time (p = 0.046). Optimal cut-off for SAF in prediction of AKI was 2.7 AU (area under the curve [AUC] 0.611), with AKI rates of 38.7% and 20.2% in patients with high and low SAF, respectively (p = 0.037). Score based on 3 independent predictors (SAF, extent of resection, and operative time) well stratified the risk of AKI (AUC 0.756), with positive and negative predictive values of 59.3% and 84.0%, respectively. In particular, SAF predicted AKI in patients undergoing major and prolonged resections (p = 0.010, AUC 0.733) with positive and negative predictive values of 81.8%, and 62.5%, respectively. Conclusions AGEs accumulation negatively affects renal function in patients undergoing liver resection. SAF measurement may be used to predict AKI after liver resection, particularly in high-risk patients.

Objective: To evaluate the predictive and diagnostic accuracy of neutrophil gelatinase-associated lipocalin (NGAL) in acute kidney injury (AKI) and also to predict the renal replacement therapy (RRT) using NGAL as a marker. Methods: This prospective study was conducted among the patients admitted to intensive care units. Plasma samples were collected 24 hours after admission and NGAL was measured using Triage® NGAL test, a specific point of care test which is based on the mechanism of fluorescence immunoassay. The diagnostic accuracy of plasma NGAL (pNGAL) to predict AKI in critically ill patients of ICU was assessed by applying receiver operator curve (ROC) analysis and calculating the area under the curve (AUC). Results: In this study, 100 patients with the mean age of 49.56±19.2 years were included for the period of 18 months. The blood samples were withdrawn from the patients 24 and 44 hours after admission. Totally, 55% (n=55) of ICU patients were diagnosed with AKI. Plasma NGAL level was significantly increased in AKI patients as compared to non-AKI patients (742.65±734.72 vs. 255.62±440.09 μg/L; P<0.01). The sensitivity and specificity of NGAL for diagnosing AKI was 83.6% and 88.9%, respectively. The overall diagnostic accuracy was 86%. Diagnostic accuracy of NGAL for requirement of RRT was 51%. Conclusion: Plasma NGAL is a reliable marker for patients with AKI in ICU, in case the cause of kidney injury is not known. In addition, NGAL also predicts the RRT need based on AKI severity.

Background: Many studies have described an association between intravenous vancomycin and nephrotoxicity; however, the majority have evaluated incidence and risk factors among hospitalized patients. Outpatient administration of intravenous antibiotics is a growing practice and presents its own set of unique challenges. Objective: The aim of this study was to identify risk factors for vancomycin-associated nephrotoxicity in the outpatient setting. Methods: A case-control study of patients who received intravenous vancomycin through an Outpatient Parenteral Antimicrobial Therapy (OPAT) program was conducted. Patients were identified who developed an acute kidney injury (AKI) during treatment. The primary outcome was the incidence of AKI during treatment. Results: A total of 37 out of 130 patients (28.5%) met the criteria for AKI. AKI was more likely to occur in patients with a longer duration of therapy, higher maximum trough concentration, co-administration of a fluoroquinolone or metronidazole, and those who received another potentially nephrotoxic medication. Co-administration of a fluoroquinolone (OR = 5.96, P = 0.009, [CI: 1.59, 24.38]), any nephrotoxic medication (OR = 11.17, P < 0.001, [CI 3.14, 51.23]), and a higher maximum vancomycin trough (OR = 1.29, P < 0.001, [CI 1.17, 1.44]) were all indicative of a higher odds of an AKI. Conclusion: In this cohort, vancomycin-associated nephrotoxicity was common during outpatient intravenous antibiotic therapy. Co-administration of a fluoroquinolone, any nephrotoxic medication, and a higher maximum vancomycin trough were associated with AKI development. Further study is needed to determine how this impacts long-term clinical outcomes and what measures can be taken to reduce nephrotoxicity risk.

Abstract Background: Acute Kidney Injury (AKI) is a sudden decline in kidney function. Early detection and prompt treatment of AKI is vital in improving the outcome of patients. We introduced in-reach nephrology services at South Tyneside District Hospital (STDH) as part of a reconfiguration of local NHS services. Aims: The principal aim of this study is to analyse patient outcomes relating to service developments and to explore prognostic characteristics among a cohort of AKI-3 patients Design: This was a single centre retrospective impact evaluation study.Methods: We studied all patients (n=246) who either presented with or developed AKI-3 during their admission at South Tyneside District Hospital from 2016 to 2018. The inclusion criteria included age 18-95 years and a diagnosis of AKI-3 as per KDIGO classification. Exclusion include those on established dialysis regime or on palliative care. Results: A total of 246 patients were admitted with AKI-3. There were 64 deaths from AKI-3 over the three-year period. Mortality decreased from 29.5% to 20.7% from 2016 to 2018. In patients with Community Acquired (CA-AKI3) the overall mortality rate was 24.2% (n=182), whereas the overall mortality rate of those with Hospital Acquired (HA-AKI3) was 31.3% (n=64). The pre-AKI use of ACEi, A2RB or diuretics increased from 39.7% in 2016 (n=78), to 59.3% in 2017 (n=86) and 64.6% in 2018 (n=82). Conversely, mortality associated with the use of these medications reduced each consecutive year (32.3%, 25.5%, 18.9%).Conclusion: Development of nephrology in-reach services, staff education measures and a primary care pathway could reduce AKI-3 mortality among patients in inpatient and community settings.

Abstract Objective This study aimed to evaluate the association between acute kidney injury (AKI) and bronchopulmonary dysplasia (BPD) in infants born <32 weeks of gestational age (GA). Study Design Present study is a secondary analysis of premature infants born at <32 weeks of GA in the Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates (AWAKEN) retrospective cohort (n = 546). We stratified by gestational age and used logistic regression to determine association between AKI and moderate or severe BPD/mortality. Results Moderate or severe BPD occurred in 214 of 546 (39%) infants, while death occurred in 32 of 546 (6%); the composite of moderate or severe BPD/death occurred in 246 of 546 (45%). For infants born ≤29 weeks of gestation, the adjusted odds ratio (OR) of AKI and the primary outcome was 1.15 (95% confidence interval [CI] = 0.47–2.86; p = 0.76). Infants born between 29 and 32 weeks of gestation with AKI had four-fold higher odds of moderate or severe BPD/death that remained after controlling for multiple factors (adjusted OR = 4.21, 95% CI: 2.07–8.61; p < 0.001). Conclusion Neonates born between 29 and 32 weeks who develop AKI had a higher likelihood of moderate or severe BPD/death than those without AKI. Further studies are needed to validate our findings and evaluate mechanisms of multiorgan injury.

Aim: NGAL, IL-18, KIM-1 as well as urinary TIMP2 and IGFBP7 and their mathematical product (TIMP2*IGFBP7) were evaluated for detecting pediatric aminoglycoside acute kidney injury (AG-AKI). Methods: In a prospective study, noncritically ill children received aminoglycosides (AG) ≥3 days. The area under the curve (AUC) for biomarkers to detect AKI was calculated by a) days before AKI onset; b) treatment days. Results: There were 113 AG episodes (68% febrile neutropenia). The AKI group had a higher proportion with febrile neutropenia. The AKI group had significantly lower NGAL 3 days before AKI, as patients with febrile neutropenia had a lower NGAL during AG treatment (p < 0.05). NGAL, IL-18 and TIMP2*IGFBP7 had AUC ≥0.73 at 3, 2 and 2 days before AKI onset. Conclusion: NGAL, IL-18 and TIMP2*IGFBP7 were modest early biomarkers of AG-AKI. Febrile neutropenia was associated with lower NGAL.

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.
