Deirdre U Sweetman
Neonatal acute kidney injury is common, in part due to incomplete renal maturation and also due to frequent exposure to risk factors for acute kidney injury such as perinatal asphyxia, extracorporeal-membrane-oxygenation, cardiac surgery, sepsis, prematurity and nephrotoxicity. However the current method by which acute kidney injury is diagnosed is sub-optimal and not universally accepted which impairs the accurate estimation of the true incidence of neonatal acute kidney injury. Serum Cystatin-C, urinary NGAL, KIM-1 and IL-18 are promising neonatal acute kidney injury biomarkers however the diagnosis of acute kidney injury remains serum creatinine/urine output-based in many studies...

OBJECTIVES: To systematically review AKI outcome prediction models and their external validation studies, to describe the discrepancy of reported accuracy between the results of internal and external validations, and to identify variables frequently included in the prediction models. METHODS: We searched the MEDLINE and Web of Science electronic databases (until January 2016). Studies were eligible if they derived a model to predict mortality of AKI patients or externally validated at least one of the prediction models, and presented area under the receiver-operator characteristic curves (AUROC) to assess model discrimination...

BACKGROUND: The cyclooxygenase (COX)-2 overexpression is associated with vascular injury and multiple organ failure in sepsis. However, constitutive COX-1 and basal COX-2 expressions have physiological effects. We aimed to investigate the effects of partial and selective COX-2 inhibition without affecting constitutive COX-1 and basal COX-2 activities by celecoxib on mesenteric artery blood flow (MABF), vascular reactivity, oxidative and inflammatory injuries, and survival in septic rats accomplished by cecal ligation and puncture (CLP)...

BACKGROUND: The prognostic significance of serum albumin levels in patients with sepsis has previously been reported; however, these studies have not excluded the potential confounding effect of exogenous albumin administration. In this study, we investigate the predictive value of serum albumin for the prognosis of severe sepsis without the interference of exogenous albumin administration. METHODS: A prospective cohort study was conducted from April to November 2014 in the internal and surgical intensive care units of a tertiary care hospital...

Renal transplant recipients infected with hepatitis C virus (HCV) have a high risk of progressing to cirrhosis, end-stage liver diseases, and hepatocellular carcinoma. It is also considered as an independent risk for graft loss and is correlated with proteinuria, transplant glomerulopathy, HCV-associated glomerulonephritis, and chronic rejection. Previous therapy involving interferon alfa and ribavirin led to treatment complications, including toxicity, anemia, sepsis, and drug-drug interactions with calcineurin inhibitors, as well as reduced tolerability and efficacy...

BACKGROUND: Infections, particularly urinary tract infections, and cardiovascular accidents are the main causes of morbidity and mortality during the 1st year after kidney transplantation (KT). Bacteria and viruses, such as Escherichia coli, Enteroccoci, and Polyoma BK virus are common in the 1st 6 months, so they are controlled routinely. On the other hand, Clostridium perfringens infection is a rare life-threatening condition, associated with a high mortality rate especially in the transplant population, that is not controlled routinely...

Organ failure is the most important determinant of the severity of acute pancreatitis (AP). Soluble fms-like tyrosine kinase 1 (sFlt-1) is positively associated with organ failure in sepsis. Our aim was to evaluate the diagnostic utility of automated sFlt-1 measurements for early prediction of AP severity. Adult patients (66) with AP were recruited, including 46 with mild (MAP), 15 with moderately-severe (MSAP) and 5 with severe AP (SAP). Serum and urine samples were collected twice. Serum sFlt-1 was measured with automated electrochemiluminescence immunoassay...

OBJECTIVES: Kidney transplant is the gold standard for treatment of renal failure. With the increasing age of the recipient population, which carries significant comorbidities, and the use of more marginal organs, there is potential for increased critical care admissions. In this study, we investigated the incidence, indications, and outcomes of patients admitted to critical care within 1 year of transplant. We also aimed to identify any precipitating factors or events that may trigger these admissions, as well as establish variables that could affect mortality...

Data on sepsis prevalence on the general wards is lacking on the UK and in the developed world. We conducted a multicentre, prospective, observational study of the prevalence of patients with sepsis or severe sepsis on the general wards and Emergency Departments (ED) in Wales. During the 24-hour study period all patients with NEWS≥3 were screened for presence of 2 or more SIRS criteria. To be eligible for inclusion, patients had to have a high clinical suspicion of an infection, together with a systemic inflammatory response (sepsis) and evidence of acute organ dysfunction and/or shock (severe sepsis)...

BACKGROUND: Extracellular histones are cytotoxic molecules that are related to cell stress and death. They have been shown to play a crucial role in multiple pathophysiologic processes like sepsis, inflammation, vascular dysfunction and thrombosis. Their role in organ donation and graft function and survival is still unknown. The aim of this study was to assess whether an association exists between the presence of extracellular histones in machine perfusates and deceased donor kidney viability...

Hematopoietic stem cell transplantation (HSCT) is a highly effective treatment strategy for lymphoproliferative disorders and bone marrow failure states including aplastic anemia and thalassemia. However, its use has been limited by the increased treatment related complications, including acute kidney injury (AKI) with an incidence ranging from 20% to 73%. AKI after HSCT has been associated with an increased risk of mortality. The incidence of AKI reported in recipients of myeloablative allogeneic transplant is considerably higher in comparison to other subclasses mainly due to use of cyclosporine and development of graft-versus-host disease (GVHD) in allogeneic groups...

BACKGROUND: The world's population is aging faster and the incidence of acute kidney injury (AKI) needing continuous renal replacement therapy (CRRT) is increasing in elderly population. The outcome of AKI needing CRRT in elderly patients is known to be poor. However, the definitions of elderly used in the previous literatures were diverse and, there were few data that compared the long-term mortality rates of these patients with middle aged patients. This study was aimed to evaluate this issue...

RATIONALE: Acute kidney injury may contribute to distant organ dysfunction. Few studies have examined kidney injury as a risk factor for delirium and coma. OBJECTIVE: To examine whether acute kidney injury is associated with delirium and coma in critically ill adults. METHODS: In a prospective cohort study of ICU patients with respiratory failure and/or shock, we examined the association between acute kidney injury and daily mental status using multinomial transition models adjusting for demographics, non-renal organ failure, sepsis, prior mental status, and sedative exposure...

Hyponatremia is commonly noted with cardiovascular disorders, but its role in infective endocarditis (IE) is limited to being a marker of increased morbidity in IE patients with intravenous drug use. This was a 5-year retrospective review from an Indian Intensive Care Unit (ICU). Patients >18 years with IE and available serum sodium levels were included in the study. Pediatric and pregnant patients were excluded from the study. Hyponatremia was defined as admission sodium <135 mmol/L. Detailed data were abstracted from the medical records...

BACKGROUND: Histamine assumes an important role as a major mediator in various pathologic disorders associated with inflammation and immune reactions. However, the involvement of histamine in the pathological conditions and symptoms of sepsis remains entirely unknown. In this study, we establish that histamine is identified as a contributory mediator to promoting the development of organ injury in sepsis. METHODS: Histidine decarboxylase (HDC) gene knockout (HDC(-/-)) mice, histamine H1-/H2-receptor gene-double knockout (H1R(-/-)/H2R(-/-)) mice, and their littermate wild-type (WT) C57BL/6J mice underwent cecal ligation and puncture (CLP) or sham operation...
