Abstract Background Acute kidney injury (AKI) is a key risk factor for chronic kidney disease in the general population, but has not been investigated in detail among renal transplant recipients (RTRs). We investigated the incidence, severity and risk factors for AKI following cardiac surgery among RTRs compared with non-RTRs with otherwise similar clinical characteristics. Methods We conducted a retrospective cohort study of RTRs (n = 83) and non-RTRs (n = 83) who underwent cardiac surgery at two major academic medical centers. Non-RTRs were matched 1:1 to RTRs by age, preoperative (preop) estimated glomerular filtration rate and type of cardiac surgery. We defined AKI according to Kidney Disease: Improving Global Outcomes criteria. Results RTRs had a higher rate of AKI following cardiac surgery compared with non-RTRs [46% versus 28%; adjusted odds ratio 2.77 (95% confidence interval 1.36–5.64)]. Among RTRs, deceased donor (DD) versus living donor (LD) status, as well as higher versus lower preop calcineurin inhibitor (CNI) trough levels, were associated with higher rates of AKI (57% versus 33% among DD-RTRs versus LD-RTRs; P = 0.047; 73% versus 36% among RTRs with higher versus lower CNI trough levels, P = 0.02). The combination of both risk factors (DD status and higher CNI trough level) had an additive effect (88% AKI incidence among patients with both risk factors versus 25% incidence among RTRs with neither risk factor, P = 0.004). Conclusions RTRs have a higher risk of AKI following cardiac surgery compared with non-RTRs with otherwise similar characteristics. Among RTRs, DD-RTRs and those with higher preop CNI trough levels are at the highest risk.

Purpose: Acute kidney injury (AKI) is a severe complication in medical and surgical intensive care units accounting for a high morbidity and mortality. Incidence, risk factors, and prognostic impact of this deleterious condition are well established in this setting. Data concerning the neurocritically ill patients is scarce. Therefore, aim of this study was to determine the incidence of AKI and elucidate risk factors in this special population. Methods: Patients admitted to a specialized neurocritical care unit between 2005 and 2011 with a length of stay above 48 hours were analyzed retrospectively for incidence, cause, and outcome of AKI (AKI Network-stage ≥2). Results: The study population comprised 681 neurocritically ill patients from a mixed neurosurgical and neurological intensive care unit. The prevalence of chronic kidney disease (CKD) was 8.4% (57/681). Overall incidence of AKI was 11.6% with 36 (45.6%) patients developing dialysis-requiring AKI. Sepsis was the main cause of AKI in nearly 50% of patients. Acute kidney injury and renal replacement therapy are independent predictors of worse outcome (hazard ratio [HR]: 3.704; 95% confidence interval [CI]: 1.867-7.350; P < .001; and HR: 2.848; CI: 1.301-6.325; P = .009). Chronic kidney disease was the strongest independent risk factor (odds ratio: 12.473; CI: 5.944-26.172; P < .001), whereas surgical intervention or contrast agents were not associated with AKI. Conclusions: Acute kidney injury in neurocritical care has a high incidence and is a crucial risk factor for mortality independently of the underlying neurocritical condition. Sepsis is the main cause of AKI in this setting. Therefore, careful prevention of infectious complications and considering CKD in treatment decisions may lower the incidence of AKI and hereby improve outcome in neurocritical care.

<p class="abstract"><strong>Background:</strong> Traditional risk factors like elevated homocysteine levels may not completely explain the higher CVD seen in RTRs. Identification and optimisation of modifiable risk factors may help to reduce the occurrence of CVD in such population. To study the role of homocysteine level as risk factor in the occurrence of cardiovascular events in renal transplant patients. Another objective was to evaluate the other risk factors in the occurrence of CVD in such population.</p><p class="abstract"><strong>Methods:</strong> Thirty renal transplant recipients and thirty healthy controls were studied. Inclusion criteria were transplant duration &gt;6 months and patients with chronic stable renal function over the last 3 months. Samples for fasting plasma homocysteine were collected and plasma homocysteine was then estimated. All the patients were followed up every month for 6 months and evaluated for occurrence of any cardiovascular event.</p><p class="abstract"><strong>Results:</strong> The mean hornocysteine levels were found to be 27.4±7.902 µmol/L in cases and 10.86±1.98 µmol/L in controls. There was no statistically significant relationship between homocysteine levels and transplant duration, mean IMT levels, proteinuria, and presence of left ventricular hypertrophy or choice of immunosuppressive regimen. Of the 30 patients, 6 patients (20%) had evidence of cardiovascular event. In the absence of other conventional factors, age of the patient, creatinine clearance (index of graft function) and mean intima-media thickness were more closely related with cardiovascular events.  </p><p><strong>Conclusions:</strong> Plasma homocysteine failed to show as an independent risk factor for cardiovascular events. New, emerging cardiovascular risk factors (e.g. Lipoprotein (a), high sensitivity C-reactive protein, fibrinogen, tissue plasminogen activator and plasminogen activator inhibitor-1) should be studied to design effective therapy to delay the progression of atherosclerosis and prolong the life of renal transplant recipients.</p>

Background: Acute kidney injury (AKI) is a common and serious complication faced by children following ventricular septal defect (VSD) surgery with cardiopulmonary bypass (CPB). The objective of this study was to explore potential predictors inherent to AKI.Methods: VSD infants who were scheduled for elective cardiac surgery with CPB from 2017 to 2020 were enrolled in this study. Based on the Pediatric Risk, Injury, Failure, Loss, End-Stage Renal Disease (pRIFLE) criteria, patients were divided into AKI and non-AKI groups. Univariate and multivariate logistic regression analyses were carried out in order to evaluate potential risk factors for AKI. Receiver operating characteristic (ROC) curves were generated to evaluate the predictive probabilities of risk factors for AKI.Results: Of all the 338 enrolled VSD infants, 49 manifested AKI with an incidence of 14.5% (49/338). The ROC curve indicated that albumin-to-fibrinogen ratio (AFR) during CPB was a significant predictor of AKI [area under the curve (AUC), 0.711; p &lt; 0.001]. Based on the univariate and multivariate logistic analyses, AFR during CPB [odds ratio (OR), 1.89; 95% confidence interval (CI), 1.22–2.76, p = 0.011] was the only independent risk factor for AKI.Conclusions: This study demonstrated that a low AFR (&lt;9.35) during CPB was an independent risk factor for AKI in VSD infants following cardiac surgery with CPB.
