Purpose: The objective of this study was to determine: 1) the incidence and the risk factors of diclofenac/acetaminophen combination as a single agent induced Acute Kidney Injury (AKI) in postoperative pain relief 2) the average cost and length of hospital stay for patients in AKI group and non-AKI group. Methods: All patients with no prior history of chronic kidney disease (CKD) and normal serum creatinine [44~130 μmol /l] who received diclofenac and acetaminophen combination as a single agent intramuscularly (IM) between January and December 2015 in The Second Xiangya Hospital, Changsha, Hunan, China were included in this retrospective own-control study. Baseline serum creatinine (SCr) and SCr during NSAID use were collected. AKI is defined as an increased of Scr over 1.5 times the baseline. Multivariate analyses were performed with a logistic regression model to assess the significant risk factors of AKI. Results: A total of 821 patients were included in the study with 63 [7.7%] patients had diclofenac/acetaminophen combination single agent induced AKI. Multivariate analysis confirmed that using diclofenac/acetaminophen combination after surgeries within 24 h were significantly associated with AKI [odds ratio, OR, 2.173; 95% CI, 1.113-4.243; P=0.023]. The average cost and length of hospitalization in AKI group was 1.87 times [p=0.000] and 1.2 times [p=0.043] comparison than non-AKI group, respectively. Conclusions: The incidence of diclofenac/acetaminophen combination single agent induced AKI in postoperative pain relief was 7.7%. Patients with hypertension or liver cirrhosis was more likely to develop AKI and using diclofenac/acetaminophen combination after surgeries within 24 h was significant risk factors for AKI. AKI prolonged the cost and length of hospitalization. This article is open to POST-PUBLICATION REVIEW.

Incidence And Mortality

Background: Septicemia remains a leading cause of morbidity and mortality among neonates with AKI complicating as many as 3.4 to 24% of them. The actual incidence of renal failure in all sepsis cases is not documented. There are several studies in the literature on renal failure in neonates which were based on older definitions using blood urea and urine output as parameters. The major limitation of the older studies was that they did not use the current acute kidney injury network (AKIN) definition. In the present study, we have attempted to investigate AKI in neonatal sepsis using the AKIN definition based on serum creatinine (Table1). We also attempted to determine the predictors of AKI in neonatal sepsis.Methods: The present study was an explorative study conducted in the neonatal unit of Cheluvamba hospital attached to Mysore Medical College and Research Institute in which a total of 50 neonates with clinical/ culture positive sepsis were enrolled during the period of June 2014 to June 2015.Results: These neonates were investigated for the presence of AKI based on serum creatinine values of three consecutive days and were divided into two groups. Group 1 consisted of septic neonates with AKI and group 2 consisted of septic neonates without AKI. Both the groups were followed up till discharge or death. The risk factors associated with sepsis were compared in both the groups and predictors of morbidity and mortality associated with AKI in sepsis were also determined.Conclusions: Incidence and mortality associated with AKI in sepsis was found to be 24% and 75% respectively. Factors like PROM, foul smelling liquor, > 3 unclean vaginal examinations during labour were significant risk factors for development of AKI in sepsis. Culture positivity, associated meningitis, DIC, shock and need for assisted ventilation were poor prognostic indicators and were significantly associated with mortality.

Abstract Background The use of intraoperative topical vancomycin (VAN) is a strategy aimed to prevent surgical site infections (SSI). Although there is evidence to support its efficacy in SSI prevention following orthopedic spine surgeries, data describing its safety, specifically acute kidney injury (AKI) risk, is limited. The purpose of this study was to determine the AKI incidence associated with intraoperative topical VAN. Methods This is a retrospective cohort study reviewing patient encounters where intraoperative topical VAN was administered from February 2018 to July 2018. All adult patients ( ≥18 years) that received topical VAN in the form of powder, beads, rods, paste, cement spacers, or unspecified topical routes were included. Patient encounters were excluded for AKI or renal replacement therapy (RRT) at baseline, ≤ 2 serum creatinine values drawn after surgery, and/or if irrigation was the only topical formulation given. The primary outcome was the percentage of patients who developed AKI after intraoperative topical VAN administration. AKI was defined as an increase in serum creatinine (SCr) ≥50% from baseline, an increase in SCr >0.5 from baseline, or0 if RRT was initiated after topical VAN was given. Secondary outcomes included analysis of AKI risk factors and SSI incidence. AKI risk factors were analyzed using a multivariable logistic regression model. Results A total of 589 patient encounters met study criteria. VAN powder was the most common formulation (40.9%), followed by unspecified topical routes (30.7%) and beads (9.9%%). Nonspinal orthopedic surgeries were the most common procedure performed 46.7%. The incidence of AKI was 8.7%. In a multivariable logistic regression model, AKI was associated with concomitant systemic VAN (OR 3.39, [3.39–6.22]) and total topical VAN dose. Each doubling of the topical dose was associated with increased odds of developing AKI (OR = 1.42, [1.08–1.86]). The incidence of SSI was 5.3%. Conclusion AKI rates associated with intraoperative topical VAN are comparable to that of systemic VAN. Total topical vancomycin dose and concomitant systemic VAN was associated with an increased AKI risk. Additional analysis is warranted to compare these patients to a similar population that did not receive topical VAN. Disclosures All authors: No reported disclosures.

AbstractBackgroundAcute kidney injury (AKI) diagnosis requires ascertainment of change from a known baseline. Although pre-admission serum creatinine (SCr) is recommended, to date, all studies of AKI in acute stroke have used the first SCr on admission.MethodsAll patients admitted with an acute stroke to an emergency hospital were recruited. We compared use of pre-admission SCr with admission SCr to diagnose AKI. Regression analyses were used to identify risk factors for 30-day and 1-year mortality, respectively.ResultsA total of 1354 patients were recruited from December 2012 to September 2015. Incidence of AKI was 18.7 and 19.9% using pre-admission SCr and admission SCr, respectively. Diagnosis of AKI was associated with significantly increased 30-day and 1-year mortality. Diagnosis of AKI using pre-admission SCr had a stronger relationship with both 30-day and 1-year mortality. In 443 patients with a pre-admission SCr and at least two SCr during admission, AKI diagnosed using pre-admission SCr had a stronger relationship than AKI diagnosed using admission SCr with 30-day mortality [odds ratio (OR) = 2.64; 95% confidence interval (CI) 1.36–5.12; P = 0.004 versus OR = 2.10; 95% CI 1.09–4.03; P = 0.026] and 1-year mortality [hazard ratio (HR) = 1.90, 95% CI 1.32–2.76; P = 0.001 versus HR = 1.47; 95% CI 1.01–2.15; P = 0.046] in fully adjusted models.ConclusionsAKI after stroke is common and is associated with increased 30-day and 1-year mortality. Using first SCr on admission gives a comparable AKI incidence to pre-admission SCr, but underestimates 30-day and 1-year mortality risk.

Background: Chikungunya is an emerging viral infection in Bangladesh. This self-limiting febrile illness may have acute life-threating features including cardiomyopathy and encephalitis. Acute kidney injury (AKI) is less well described complication of chikungunya. This study was designed to evaluate risk factors for AKI among patients with chikungunya virus infection. Methods: This case-control study was done in 3 different centers in Dhaka, Bangladesh from July to October 2017. Adult patients (>18 years) with confirmed diagnosis of chikungunya were included in this study. AKI was diagnosed as per Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guideline for Acute Kidney Injury. Patients suffering from chikungunya complicated by AKI were cases and those without AKI were controls. Results: Total patients were 107 (male 61) with a mean age of 35.6 (range 19-84) years. Common comorbidities were diabetes mellitus (DM) (20.6%), hypertension (17.8%) and chronic kidney disease (CKD) (12.1%). Common presentations included fever (86.9%) or recent history of fever (13.1%), joint pain (88.8%), rash (23.4%), pruritus (15.9%), gastro-intestinal (GI) features like diarrhea and/or vomiting (28%), lymphadenopathy (12.1%), gum swelling/oral ulcer (4.1%) and oedema (8.4%). Fourteen (13.1%) patients required hospitalization. Eleven (10.3%) cases were complicated by AKI. Among the risk factors for AKI, comorbidities like DM (OR 28.73, 95% CI 5.57-148.10, p 0.0001) and CKD (OR 31.0, 95% CI 2.94-326.7, p <0.0001), GI features (OR 16.07, 95% CI 3.22-80.14, p 0.0007), requirement of hospitalization (OR 23.10, 95% CI 2.37-226.31, p <0.0001) and use of angiotensin converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs) (OR 6.65, 95% CI 1.77-24.98, p 0.005) were significant. Conclusions: One-tenth of adult patients suffering from chikungunya were complicated by AKI in this study. DM, CKD, diarrhea and/or vomiting, hospitalization and use of ACEIs/ARBs appeared as significant risk factors for AKI. Birdem Med J 2019; 9(3): 193-196

Introduction/Objective. Hyperchloremia is often registered in adults? studies after administration with 0.9% sodium chloride, which contributes to the development of acute kidney injury (AKI) as it leads to vasoconstriction of renal blood vessels. The aim of this study was to determine the correlation of sodium and chloride imbalance with the development of AKI, with consideration of other risk factors for this disorder. Methods. This retrospective study included 146 randomly selected preterm infants hospitalized at the Neonatal Intensive Care Unit from 2008 to 2015. Results. Among the patients registered for the study, 23.97% developed AKI, and they were of a significantly lower gestational age (26.3 ? 2.8 weeks vs. 31.7 ? 2.90 weeks, p < 0.05); birth weight (971.31 ? 412.1 g vs. 1,753.3 ? 750.3 g, p < 0.05); Apgar score in the first (3.2 ? 1.7 vs. 5.7 ? 2.4, p < 0.05) and fifth minute (5.3 ? 1.7 vs. 7.1 ? 1.8, p < 0.05) of life compared to those without AKI. The neonates with AKI had significantly higher maximum chloremia (Clmax: 114.1 ? 8.4 vs. 111.7 ? 4.6, p = 0.029) and maximum natremia (Namax: 147.9 ? 8.8 vs. 142.9 ? 4, p < 0.05). Each of these parameters is (independently) a statistically significant risk factor for the development of AKI, and gestational age is the strongest (OR = 1 / 0.643 = 1.55; 95% CI 1.24?1.94). Mortality in neonates with AKI was higher than in neonates without AKI (19.4% vs. 92.7%, p < 0.05). Conclusion. Hyperchloremia and hypernatremia are more common in the premature newborns with AKI compared to the premature newborns without AKI. Higher maximum sodium and chloride values are independent risk factors for AKI.

Introduction: Some patients with COVID-19 pneumonia present systemic disease involving multiple systems. There is limited information about the clinical characteristics and events leading to acute kidney injury (AKI). We described the factors associated with the development of AKI and explored the relation of AKI and mortality in Mexican population with severe COVID-19. Methods: We retrospectively reviewed the medical records of individuals with severe pneumonia caused by SARS-CoV-2 hospitalized at the largest third-level reference institution for COVID-19 care in Mexico between March and April 2020. Demographic information, comorbidities, clinical and laboratory data, dates of mechanical ventilation and hospitalization, mechanical-ventilator settings and use of vasoactive drugs were recorded. Results: Of 99 patients studied, 58 developed AKI (58.6%). The group with AKI had higher body mass index (p=0.0003) and frequency of obesity (p=0.001); a higher requirement of invasive mechanical ventilation (p=0.008) and vasoactive drugs (p=0.004); greater levels of serum creatinine (p<0.001) and D-dimer on admission (p<0.001); and lower lymphocyte counts (p=0.001) than the non-AKI group. The multivariate analysis indicated that risk factors for AKI were obesity (adjusted hazard ratio (HR)=2.71, 95% confidence interval (CI)=1.33-5.51, p=0.005); higher serum creatinine (HR=1.44, CI=1.02-2.02, p=0.035) and D-dimer levels on admission (HR=1.14, CI=1.06-1.23, p<0.001). In-hospital mortality was higher in the AKI group than in the non-AKI group (65.5% vs. 14.6%; p=0.001). Conclusions: AKI was common in our cohort of patients with severe COVID-19 and it was associated with mortality. The risk factors for AKI were obesity, elevated creatinine levels and higher D-dimer levels on admission. Key words: Acute kidney injury; AKI; acute renal failure; COVID-19; SARS-CoV-2.

Introduction: Children admitted to paediatric intensive care unit (PICU) are at risk of acute kidney injury (AKI). However, few paediatric studies have focused on the identification of factors potentially associated with the development of this condition. The aim of our study was to assess the incidence rate of AKI, identify risk factors, and evaluate clinical outcome in a large sample of critically ill children. Methods: This retrospective observational study was conducted including patients admitted to our PICU from January 2014 to December 2016. AKI was defined according to Kidney Disease: Improving Global Outcome criteria. Results: A total of 222 PICU patients out of 811 (27%) had AKI (stage I 39%, stage II 24%, stage III 37%). The most common PICU admission diagnoses in AKI cases were heart disease (38.6%), respiratory failure (16.8%) and postsurgical non-cardiac patients (11%). Hypoxic-ischaemic was the most frequent cause of AKI. Significant risk factors for AKI following multivariate analysis were age >2 months (OR 2.43; 95% CI 1.03–7.87; p = 0.05), serum creatinine at admission >44 µmol/L (OR 2.23; 95% CI 1.26–3.94; p = 0.006), presence of comorbidities (OR 1.84; 95% CI 1.03–3.30; p = 0.04), use of inotropes (OR 2.56; 95% CI 1.23–5.35; p= 0.012) and diuretics (OR 2.78; 95% CI 1.49–5.19; p = 0.001), exposure to nephrotoxic drugs (OR 1.66; 95% CI 1.01–2.91; p= 0.04), multiple organ dysfunction syndrome (OR 2.68; 95% CI 1.43–5.01; p = 0.002), and coagulopathy (OR 1.89; 95% CI 1.05–3.38, p = 0.03). AKI was associated with a significant longer PICU stay (median LOS of 8 days, interquartile range [IQR] 3–16, versus 4 days, IQR 2–8, in non-AKI patients; p < 0.001). The mortality rate resulted tenfold higher in AKI than non-AKI patients (12.6 vs. 1.2%; p < 0.001). Conclusions: The incidence of AKI in critically ill children is high, with an associated increased length of stay and risk of mortality. In the PICU setting, risk factors of AKI are multiple and mainly associated with illness severity.

Introduction: In Brazil, primary studies on this issue are still limited and the ideal timing of initiation of dialysis in severe acute kidney injury (AKI) still generates disagreements among experts. Objectives: To assess if the timing of initiation of dialysis is associated with the mortality of patients with AKI in intensive care unit (ICU). Patients and Methods: We retrospectively analyzed medical records of patients that developed severe AKI in the ICU. Bivariate analysis was carried out to compare data between groups of patients who underwent early dialysis (ED - initiated up to two days after the AKI diagnosis) and late dialysis (LD – initiated more than two days after the AKI diagnosis), while multivariate logistic regression was applied to identify factors associated with mortality. Results: Of the 76 patients included in the study, 27 (35.5%) were allocated in the ED group and 49 (64.5%) in the LD group. LD group had a higher frequency of sepsis [26 (53%) vs. 12 (44%); P = 0.472], while the ED group had a higher median number of dialysis sessions (6 vs. 3; P = 0.477) and higher total median time on dialysis (17.5 h vs. 13 h; P = 0.629). The overall mortality rate was 61.8% (n = 47) and of 76% (n = 22) in the ED group. The patients’ serum creatinine level at admission in the ICU was the only statistically significant risk factor for death [OR= 0.453 (95% CI= 0.257–0.801); P = 0.006]. Conclusion: The overall and in the ED group mortality rate was elevated, however, the timing of initiation of dialysis did not show statistically significant association with death. The serum creatinine at ICU admission seems to be an important mortality predictor.

Purpose of the studyThe incidence of acute kidney injury (AKI) with a poor prognosis in the elderly has been increasing each year. This study aimed to investigate the clinical characteristics of and risk factors for death from AKI in the elderly and help improve prognosis.Study designThis study was a retrospective cohort study based on data from adult patients (≥18 years old) admitted to 15 hospitals in China between 1 January 2009 and 31 December 2011. The characteristics of AKI in the elderly were compared with those in younger patients.ResultsIn elderly patients with AKI, rates of hypertension, cardiovascular disease and multiple organ dysfunction syndrome (MODS) were higher than in younger patients (44.2% vs 31.2%, 16.1% vs 4.6% and 20.9% vs 16.9%, respectively), the length of ICU stay was longer (3.8 days vs 2.7 days, P=0.019) and renal biopsy (1.0% vs 7.13%, P<0.001) and dialysis (9.6% vs 19.2%, P<0.001) were performed less. Hospital-acquired (HA) AKI was more common than community-acquired (CA) AKI (60.3% vs 39.7%), while the most common cause of AKI was pre-renal (53.5%). Multiple logistic regression analysis showed that age (OR 1.041, 95% CI 1.023 to 1.059), cardiovascular disease (OR 1.980, 95% CI 1.402 to 2.797), cancer (OR 2.302, 95% CI 1.654 to 3.203), MODS (OR 3.023, 95% CI 1.627 to 5.620) and mechanical ventilation (OR 2.408, 95% CI 1.187 to 4.887) were significant risk factors for death.ConclusionsHA-AKI and pre-renal AKI were more common in the elderly. Age, cardiovascular disease, cancer, MODS and mechanical ventilation were independent risk factors for death in the elderly with AKI.

Abstract Background and Aims The new coronavirus disease (COVID 19) has become a worldwide health emergency with a wide spectrum of clinical presentation, from common cold symptoms to multiorgan failure. A great number of medical centers have reported that patients with COVID-19 have developed acute kidney injury. The kidney is a target organ for SARS - COV2 because of ACE2 receptor, the binding site for this virus, is expressed in kidney tissue. The potential mechanisms for kidney injury are direct kidney injury, inflammation, activation of coagulation and complement cascades. Data from centers worldwide reported a wide range of AKI incidence, from 0,5% in China to 46% in USA. The aim of this study was to analyze incidence, risk factors and outcomes of AKI in hospitalized patients with COVID 19 who were treated from 01.04. to 01.06.2020. at Nephrology Department of University Clinical Center Zvezdara, which was at the time transformed into COVID hospital. Method This retrospective observational study included 51 patients who had normal kidney function before the infection with SARS COV2, and 7 of them developed dialysis non-dependent AKI. Analysis included data collection from the patients’ history including demographic, clinical and administrative data. Statistical analysis has been performed using SPSS software version 20 (IBM Corporation, New York, USA). Results Out of 51 patients 7 (13.7%) developed AKI, mean age was 59 + 16 years and 53% were male. Diabetes mellitus was present in 27 of patients with AKI, hypertension in 6/7, obesity in 3/7, coronary artery disease in 1/7 and 1 of 7 patients was smoker. These risk factors except obesity (p= 0.05) didn’t vary significantly between two groups (AKI and non AKI patients with COVID-19). Our results showed significant correlation between AKI development and obesity (p= 0.05, OR 4.75), Charlston index score (p=0.01), D dimer score (p=0.01), and CT COVID score (p=0.03). Regarding the outcome, COVID 19 patients with AKI showed 7-fold higher risk for fatal outcome (p= 0.046). Conclusion Obesity, higher D dimer values, worse CT findings and higher Charlston comorbidity score index were associated with acute kidney injury in patients with COVID 19. AKI proved to be significant risk factor for fatal outcome in patients with SARS COV2 infection.
