Markers Of Inflammation

Abstract Introduction and Aims The neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte (PLR) ratios have been identified as markers of inflammation and endothelial dysfunction in recent literature. Both are easily measured, reproducible and inexpensive, therefore cost-effective. To date, its usefulness as prognostic markers in community-acquired acute kidney injury (CA-AKI) has not been evaluated. The aim of this study was to analyze the usefulness of the NLR and PLR in terms of morbidity and mortality in community-acquired acute kidney injury. Method We established a cohort of 308 patients with community-acquired acute kidney injury (CA-AKI) admitted to the Nephrology service of a third level hospital from January 2010 to February 2015. NLR and PLR ratios were obtained with the levels of the first analysis performed at admission. Results We studied 308 patients with CA-AKI, 180 were men (58,4 %), mean age was 73.22 (±13,95). The mean length of stay was 12,25 days (±11,69). The etiology of CA-AKI was divided in prerenal 214 cases (69.5%); renal 71 cases (23.1%); obstructive 23 cases (7,5%). AKI KDIGO stages were stage I, 45 cases (14.6%); stage II, 34 cases (11%); stage III 229 cases (74.4%). Previous chronic kidney disease (CKD) was detected in 212 cases (68.8%). A total of 54 patients (17,15%) required hemodialysis and 38 patients died during admission (12.3%). Mean NLR was 9.14 ± 8,47 (95% IC 8,2-10,1). Mean PLR was 236,99 ± 228,41 (95% IC 211,38-262,6). NLR according to etiology was: prerenal 8,55±6,8; renal 9,37±9,8; obstructive 13,99±14,82 (significant differences of the latter group compared to the prerenal group). PLR according to etiology: prerenal 228,31±216,34; renal 236,15±233,77; obstructive 320,37±304,89 (non-significant differences). Within the group of prerenal origin, 79 cases were complicated by the development of acute tubular necrosis (ATN). These cases presented a higher NLR (NLR of ATN 10,7±10,28 vs NLR of pure prerenal 7,8±5,6; p=0,026). There were no significant differences between the PLR of the pure prerenal group and the group with ATN (225,95±262,54 vs 285,78±278,61). The NLR showed a significant correlation with the peak creatinine (r= 0,186; p = 0,001) and with the serum albumin (r= -0,237; p < 0,001). The PLR also showed correlation with the peak creatinine (r= 0,134, p = 0,018) and the serum albumin (r = 0,165, p= 0,07).The NLR, but not the PLR, was associated with the length of hospital stay (multiple linear regression analysis). Through a multivariate binary logistic regression analysis, the variables that were independently associated with mortality during admission were the Liaño individual severity index and the NLR (OR 1,060; IC 95 % 1.014 – 1,108). The variables that were ruled out by the model were sex, age, Charlson comorbidity index, peak creatinine, serum albumin, chronic kidney disease, etiology of AKI (prerenal vs. non prenal), potassium, KDIGO stage of AKI, need of hemodialysis and PLR. The best cut-off point of the NLR to predict mortality was 6,68 (AUC 0,584; sensitivity 0.60; specificity 0.58; Youden index 0.178) Conclusion In our cohort of patients affected by CA-AKI, the NLR was associated with the morbidity and the mortality during admission. More studies are need to confirm this finding, but the easiness of obtaining it and its economic cost make it cost-effective, giving the NLR a leading role in assessing the risk of CA-AKI.

Abstract Background This study aimed to investigate the association of acute kidney injury (AKI) with change in estimated glomerular filtration rate (eGFR) in children with advanced chronic kidney disease (CKD). Methods Single centre, retrospective longitudinal study including all prevalent children aged 1–18 years with nondialysis CKD stages 3–5. Variables associated with CKD were analysed for their potential effect on annualised eGFR change (ΔGFR/year) following multiple regression analysis. Composite end-point including 25% reduction in eGFR or progression to kidney replacement therapy was evaluated. Results Of 147 children, 116 had at least 1-year follow-up in a dedicated CKD clinic with mean age 7.3 ± 4.9 years with 91 (78.4%) and 77 (66.4%) with 2- and 3-year follow-up respectively. Mean eGFR at baseline was 29.8 ± 11.9 ml/min/1.73 m2 with 79 (68%) boys and 82 (71%) with congenital abnormalities of kidneys and urinary tract (CAKUT). Thirty-nine (33.6%) had at least one episode of AKI. Mean ΔGFR/year for all patients was − 1.08 ± 5.64 ml/min/1.73 m2 but reduced significantly from 2.03 ± 5.82 to − 3.99 ± 5.78 ml/min/1.73 m2 from youngest to oldest age tertiles (P < 0.001). There was a significant difference in primary kidney disease (PKD) (77% versus 59%, with CAKUT, P = 0.048) but no difference in AKI incidence (37% versus 31%, P = 0.85) between age tertiles. Multiple regression analysis identified age (β = − 0.53, P < 0.001) and AKI (β = − 3.2, P = 0.001) as independent predictors of ΔGFR/year. 48.7% versus 22.1% with and without AKI reached composite end-point (P = 0.01). Conclusions We report AKI in established CKD as a predictor of accelerated kidney disease progression and highlight this as an additional modifiable risk factor to reduce progression of kidney dysfunction.

Background: Here we aimed to investigate the predictors of catheter-related bloodstream infections (CRBSI) in patients with acute kidney injury or chronic kidney disease who required renal replacement therapy through a non-tunneled hemodialysis catheter. Methods: A total of 111 patients who received non-tunneled hemodialysis catheters were retrospectively evaluated. Patients were divided into two groups; those who developed CRBSI and those who did not. Patient’s demographic data, laboratory results at admission, information regarding catheter infections, and culture results were obtained from electronic medical records. Results: The mean age of the patients was 64 ± 16 years, and 51 of them were male. CRBSI occurred in 14 patients (12.6%). Admission serum albumin level (OR: 0.119, 95% CI: 0.019–0.756, p = 0.024), admission mean platelet volume (OR: 2.207, 95% CI: 1.188–4.100, p = 0.012) and catheter duration (OR: 1.580, 95% CI: 1.210–2.064, p = 0.001) were independent predictors for the CRBSI development. ROC curve analysis demonstrated that a catheter duration of 22 days was predictive for presence of CRBSI (78% sensitivity, 76% specificity, AUC: 0.825, 95% CI: 0.724–0.925, p < 0.001). Conclusions: Prolonged catheter duration, low serum albumin, and high mean platelet volume independently predict the development of CRBSI in patients undergoing hemodialysis for acute kidney injury or chronic kidney disease.

<strong>Background:</strong> Acute kidney injury is a common complication of cardiac surgery that increases morbidity and mortality. The aim of the present study is to analyze the association of preoperative serum albumin levels with acute kidney injury and the requirement of renal replacement therapy after isolated coronary artery bypass graft surgery (CABG).<br /><strong>Methods:</strong> We retrospectively reviewed the prospectively collected data of 530 adult patients who underwent isolated CABG surgery with normal renal function. The perioperative clinical data of the patients included demographic data, laboratory data, length of stay, in-hospital complications and mortality. The patient population was divided into two groups: group I patients with preoperative serum albumin levels &lt;3.5 mg/dL; and group II pateints with preoperative serum albumin levels ≥3.5 mg/dL.<br /><strong>Results:</strong> There were 413 patients in group I and 117 patients in group II. Postoperative acute kidney injury (AKI) occured in 33 patients (28.2%) in group I and in 79 patients (19.1%) in group II. Renal replacement therapy was required in 17 patients (3.2%) (8 patients from group I; 9 patients from group II; P = .018). 30-day mortality occurred in 18 patients (3.4%) (10 patients from group I; 8 patients from group II; P = .037). Fourteen of these patients required renal replacement therapy. Logistic regression analysis revealing the presence of lower serum albumin levels preoperatively was shown to be associated with increased incidence of postoperative AKI (OR: 1.661; 95% CI: 1.037-2.661; <br />P = .035). Logistic regression analysis also revealed that DM (OR: 3.325; 95% CI: 2.162-5.114; P = .000) was another independent risk factor for AKI after isolated CABG. <br /><strong>Conclusion:</strong> Low preoperative serum albumin levels result in severe acute kidney injury and increase the rate of renal replacement therapy and mortality after isolated CABG.

AbstractPostoperative acute kidney injury (PO-AKI) is a common complication of major surgery that is strongly associated with short-term surgical complications and long-term adverse outcomes, including increased risk of chronic kidney disease, cardiovascular events and death. Risk factors for PO-AKI include older age and comorbid diseases such as chronic kidney disease and diabetes mellitus. PO-AKI is best defined as AKI occurring within 7 days of an operative intervention using the Kidney Disease Improving Global Outcomes (KDIGO) definition of AKI; however, additional prognostic information may be gained from detailed clinical assessment and other diagnostic investigations in the form of a focused kidney health assessment (KHA). Prevention of PO-AKI is largely based on identification of high baseline risk, monitoring and reduction of nephrotoxic insults, whereas treatment involves the application of a bundle of interventions to avoid secondary kidney injury and mitigate the severity of AKI. As PO-AKI is strongly associated with long-term adverse outcomes, some form of follow-up KHA is essential; however, the form and location of this will be dictated by the nature and severity of the AKI. In this Consensus Statement, we provide graded recommendations for AKI after non-cardiac surgery and highlight priorities for future research.
