THE AIM. Assessment of the impact of renal dysfunction and imbalance of body aquatic environments distribution on the risk of developing cardiovascular complications in the late period after acute coronary syndrome (ACS) and myocardial revascularization. PATIENTS AND METHODS. We examined 120 patients with ACS undergoing myocardial revascularization. We estimated traditonal and renal risk factors (albuminuria 30-300 mg/l, the value of GFR, acute kidney injury development), and body aquatic environments factors. Upon completion of the primary material processing, to determine the effect of the studied risk factors, we selected combined endpoint of the study – development of arrhythmias or death of patients, which were registered 6 months after restoration of coronary blood flow. RESULTS. By results of the carried out research we established effect on the probability of cardiovascular complications (CVC) by such risk factors as the presence of albuminuria, and acute kidney injury (AKI). AKI episode in patients with ACS associated with increase of arrhythmias and death possibilities in late period. It is established that AKI coupled with an imbalance of body aquatic environments increases the CVC development possibility 6 months after percutaneous coronary intervention in patients with ACS. CONCLUSION. In patients with ACS and myocardial revascularization revealed prognostic impact of the AKI and failure of body aquatic environments at the risk of CVC.

Abstract Aims Small sub-study data derived from randomized clinical trials suggest a gender-based disparity in TAVI outcomes. However, large real-world contemporary data is missing. The aim of this study is to compare the risk factors, procedural characteristics and clinical outcomes of male and female patients who underwent transcatheter aortic valve implantation (TAVI) using two next-generation self-expandable bioprostheses (ACURATE neo and Evolut R/Pro valves). Methods We performed a first unmatched comparison and a propensity score-matched analysis (PSM) to assess the outcomes derived by the sex difference beyond the impact of pre-procedural risk factors in a large, contemporary, real-world, multicentre, international, retrospective registry of 3862 consecutive patients. The primary endpoint was a composite of all-cause death or any stroke (disabling and non-disabling) at 1 year. Results Sixty-four per cent (2162/3353 patients) of the study cohort was female and was older (mean age 82.3 years vs. 81.1 years for men (P<0.001)) had a higher BMI (27.7±5.7 for women vs. 27.2±4.5 for men), and lower prevalence of dyslipidaemia (50.2% vs. 54.7, P=0.037), diabetes (26.8% vs. 33.7, P<0.001), smoking (10.0% vs. 24.3%, P<0.001), COPD (17.4% vs. 21.9%, P=0.002), pacemaker/ICD (9.6% vs. 14.0%, P<0.001), previous cardiac surgery (8.6% vs. 18.8%, P<0.001), previous PCI (23.0% vs. 36.8%, P<0.001). Mean STS score for women was higher 5.2±3.9% vs. 4.5±3.4% (P<0.001). Women had higher mean valve gradients (45.4±17.1 vs. 42.7±14.7 mmHg; P<0.001), smaller valve areas (mean 0.7 cm2 vs. 0.9 cm2, P=0.037) and smaller annular perimeters (56.8±23.0 vs. 62.0±23.8, P<0.001). The primary endpoint was resulted in a rate of 7.9% vs. 6.9% (P=0.337) in the unmatched population and 9.4% vs. 6.0% (P=0.014) after the PSM, respectively for women and for men. Independently, there was no difference in mortality (5.9% vs. 5.6%; P=0.786) and stroke (2.5% vs. 1.8%; P=0.243) rates between women and men in the un-matched groups. Rates of cardiac tamponade (1.5% vs. 0.4%, P=0.008), major vascular complications (7.7% vs. 4.1%, P<0.001), life-threatening bleeding (2.8% vs. 1.4%, P=0.016), major bleeding (5.1% vs. 2.9%, P=0.004), need of transfusion (8.9% vs. 4.6%, P<0.001) and acute kidney injury (8.5% vs. 5.7%, P=0.009), were all significantly higher in women. After PSM, mortality was similar between the two groups (11.3% for women vs. 9.5% for men, P=0.264) but strokes were more prevalent in women (2.8% vs. 1.2%, P<0.024). Furthermore, in the matched population, major vascular complications (6.8% vs. 4.1%, P=0.024), need of transfusion (9.1% vs. 4.6%, P<0.001) and acute kidney injury (8.7% vs. 5.6%, P=0.009) remained significantly different between women and men, respectively. Conclusions In this large real-world contemporary TAVI registry, female gender was associated with higher rates of stroke, vascular complications, major bleeding, and acute kidney injury. Further studies are required to explore the underlying pathophysiological mechanisms for these observations.

Introduction: Acute kidney injury (AKI) is one of the major complications after allogeneic hematopoietic cell transplantation (allo-HCT), and several studies have demonstrated a relationship between poor outcome and the concomitant AKI in the early phase after allo-HCT. Among various post-transplant factors, usage of antimicrobial agents, especially in cases where multiple agents are combined, may be one of the major causes of post-transplant AKI, due the potential nephrotoxicity of each agent and drug-drug interactions. An association between the combination of vancomycin (VCM) with piperacillin/tazobactam (PIPC/TAZ) and increased risk of developing AKI after allo-HCT has been reported; however, no reports have demonstrated the impact of other combinations on post-transplant AKI. Herein, we performed a retrospective analysis to compare the incidence of AKI according to selected antimicrobial agents, using a database with information covering the time-dependent administrative status of all the agents involved. Methods: We included patients with hematological malignancies who received allo-HCT between 2006 and 2018 in Kyoto University, Kyoto, Japan to evaluate the incidence and risk factors of AKI early after transplantation (before Day100). The incidence of AKI was defined according to Acute Kidney Injury Network (AKIN) classification and evaluated, considering early death as a competing risk. Administrative status of each antimicrobial agent was treated as a time-dependent covariate, and the synergetic effects on AKI by multiple agents in combination were evaluated as p for interaction. Results: In total, 465 transplant cases (416 patients) were included. The median age at HCT was 49 years old (range, 17-70). Among these, 104 cases received a related-donor transplant (64 patients received bone marrow and 40 peripheral-blood stem cell grafts), 207 received a transplant from unrelated donors, and 154 received a single-unit cord-blood transplant. The median value for pre-transplant serum creatinine (sCr) was 0.6 (range, 0.20-1.68). The cumulative incidence of AKI at Day100 was 40.0%, and overall survival (OS) at 3 years after HCT was 43.5% in patients with AKI while 70.9% in those without AKI (hazard ratio [HR] = 2.63, 95% confidence interval = 1.95-3.55, p < 0.01). Being male and having a higher pre-transplant sCr were significant risk factors for AKI (HR = 1.53, p < 0.01 and HR = 4.21, p < 0.01, respectively). After HCT, 34 types of oral or intravenous antimicrobial agents (17 antibiotics, 6 antivirals, and 11 antifungals) were utilized across the entire cohort. A higher incidence of AKI was significantly associated with the use of intravenous ciprofloxacin, foscarnet (FCN), ganciclovir (GCV), liposomal amphotericin B (L-AMB), meropenem (MEPM), PIPC/TAZ, and VCM (p < 0.05). Next, we investigated the synergistic impacts of using anti-pseudomonal antibiotics and anti-methicillin resistant staphylococcus aureus (MRSA) agents, because empiric treatment of febrile neutropenia after HCT often relies on this combination, i.e. CFPM, PIPC/TAZ, or MEPM in combination with VCM or teicoplanin (TEIC). As a result, sole administration of VCM was associated with a higher incidence of AKI; this effect was enhanced when VCM was used in combination with PIPC/TAZ (HR = 3.03, p < 0.01 for VCM without PIPC/TAZ; HR = 4.38, p < 0.01 for VCM with PIPC/TAZ), indicating the existence of interaction between VCM and PIPC/TAZ. However, for the concomitant use of VCM plus CFPM or MEPM, no synergistic interaction was observed with regard to the increased incidence of AKI. In addition, administration of TEIC alone and any combination used with TEIC were not associated with an increased risk of AKI. An increased risk of AKI was also confirmed for the combination of MEPM plus GCV or FCN, and GCV plus L-AMB. Conclusions: AKI was significantly associated with poorer OS, and specific antimicrobial combinations were suggested to increase the risk of AKI. Avoidance of such combinations should be considered to preserve renal function and to reduce AKI-related morbidity and mortality. Disclosures No relevant conflicts of interest to declare.

Despite their common use as an empirical combination therapy for the better part of a decade, there has been a recent association between combination therapy with vancomycin and piperacillin-tazobactam and high rates of acute kidney injury (AKI). The reasons for this increased association are unclear, and this analysis was designed to investigate the association. Retrospective cohort and case-control studies were performed. The primary objective was to assess if there is an association between extended-infusion piperacillin-tazobactam in combination with vancomycin and development of AKI. The secondary objectives were to identify risk factors for AKI in patients on the combination, regardless of infusion strategy, and to evaluate the impact of AKI on clinical outcomes. AKI occurred in 105/320 (33%) patients from the cohort receiving combination therapy with vancomycin and piperacillin-tazobactam, with similar rates seen in those receiving intermittent (53/160 [33.1%]) and extended infusions (52/160 [32.5%]) of piperacillin-tazobactam. Independent risk factors for AKI in the cohort included having a documented Gram-positive infection, the presence of sepsis, receipt of a vancomycin loading dose (odds ratio [OR], 2.22; 95% confidence interval [CI], 1.05 to 4.71), and receipt of any concomitant nephrotoxin (OR, 2.44; 95% CI, 1.41 to 4.22). For at-risk patients remaining on combination therapy, the highest rates of AKI occurred on days 4 (10.7%) and 5 (19.3%). The incidence of AKI in patients on combination therapy with vancomycin and piperacillin-tazobactam is high, occurring in 33% of patients. Receipt of piperacillin-tazobactam as an extended infusion did not increase this risk. Modifiable risk factors for AKI include receipt of a vancomycin loading dose, concomitant nephrotoxins, and longer durations of therapy.

Abstract Several potential risk factors are being evaluated for their impact on the development of chronic kidney disease (CKD) in patients with Sickle Cell Disease (SCD). Recent studies in animals, children and adults without SCD, have established that acute kidney injury (AKI) can lead to CKD, yet the risk of repeated AKI events during vaso-occlusive crisis (VOC) has not been defined in SCD. During VOC events, patients may be at risk for developing AKI due to the use of nephrotoxic pain medications, dehydration (poor concentrating ability), hemolysis, or inflammatory responses. Multiple gaps in our understanding of AKI in SCD patients need to be addressed. Methods: In order to improve our understanding of the incidence, risk factors, and outcomes associated with AKI, we conducted a two year IRB approved retrospective review of 234 episodes of ICD-10 defined VOC admitted from Children's of Alabama Pediatric Emergency Department (ED). AKI was defined by KDIGO definition of an increase in serum creatinine (SCr) by ≥ 0.3 mg/dl or 50% increase in serum creatinine from baseline. Baseline labs were defined as the most recent outpatient laboratory value and within 12 months from admission. Thirty seven admissions were excluded as their baseline SCr could not be established. Variables analyzed included age, gender, SCD genotype, baseline and admission CBC (hemoglobin (Hb) value, white blood cell count (WBC), absolute neutrophil count (ANC), platelet count, and absolute reticulocyte count (ARC)), length of stay (LOS), and SCD modifying therapy. Generalized mixed effects model for binary outcome with random intercept, to accommodate repeated hospitalizations for the same subject, was fitted to assess the associations between clinical variables and AKI for all patients and severe phenotypes. Similarly, a generalized mixed Poisson effects model with random intercept was fitted to determine if AKI was independently associated with hospital length of stay. Results: Among 197 admissions for VOC, 33 (17%) were identified with AKI. Seventeen (52%) of the thirty three AKI events were first diagnosed in the ED. Compared to children without AKI, patients with AKI had a larger drop in hemoglobin from baseline at admission (0.5 vs. 1.21g/dL, p=0.005). For every 1 unit drop in Hb from baseline to admission, the odds of AKI increased by 49% (OR= 1.49, 95% CI 1.1-2.0). We identified no differences in AKI vs. no AKI by age, gender, SCD genotype, or SCD modifying therapy, change in WBC, ANC, Platelets or absolute reticulocyte count. In multivariate analysis accounting for age, gender, change in blood counts, SCD genotype or therapy, a drop in Hb remained the only significant variable (OR= 1.48, 95% CI 1.05-2.1). Patients with AKI admitted for vaso-occlusive crisis required significantly longer length of stay. The average LOS for those with AKI was 32% longer than the without AKI (OR 1.32, 95% CI 1.10-1.58). Conclusion: Seventeen percent of SCD patients with pain admitted to the hospital can present with or develop AKI. An acute drop in hemoglobin is a major risk factor for developing AKI. Patients that develop AKI require longer hospitalizations for their pain crisis, independent of potential confounders. Research should focus on pathophysiology of kidney injury in patients with SCD, the impact of nephrotoxic medications, and the role by which AKI leads to CKD in this population.

The Impact

Background: Both the Norwood procedure and acute kidney injury (AKI) are associated with significant morbidity and mortality. The impact of AKI by measured and fluid corrected serum creatinine on outcomes after the Norwood procedure has not been previously studied. The purpose of this study was to (1) identify the incidence of AKI, (2) determine AKI risk factors, and (3) evaluate outcomes in patients with AKI using both measured and fluid corrected serum creatinine. Methods: Single-center retrospective chart review from 2009 to 2015 including neonates who underwent the Norwood procedure. Acute kidney injury was defined by the Kidney Disease Improving Global Outcomes staging criteria using both measured and fluid corrected serum creatinine. Multivariable logistic regression analysis was performed to determine the risk factors associated with AKI. Results: Ninety-five neonates underwent the Norwood procedure. Correcting for fluid overload increased the incidence of AKI from 40% to 44%, increased AKI severity in 15 patients, and improved the identification of adverse outcomes associated with AKI. Patients palliated with the modified Blalock-Taussig shunt (mBTS) had a 9.4 greater odds of fluid corrected AKI compared to those palliated with a right ventricle to pulmonary artery conduit (95% confidence interval [95% CI]: 1.68-52.26, P = .01). A higher vasoactive inotrope score (VIS) on postoperative day (POD) 0 was associated with fluid corrected AKI (odds ratio: 1.20, 95% CI: 1.06-1.35; P = .003). Conclusions: Acute kidney injury is common after the Norwood procedure. Correcting creatinine for fluid balance revealed new cases of AKI. Use of an mBTS and higher VIS on POD 0 were associated with increased risk of AKI.
