AbstractGlomerular filtration rate (GFR) is difficult to measure, and estimating formulas are notorious for lacking precision. This study aims to assess if the inclusion of additional biomarkers improves the performance of eGFR formulas. A hundred and sixteen children with renal diseases were enrolled. Data for age, weight, height, inulin clearance (iGFR), serum creatinine, cystatin C, neutrophil gelatinase-associated lipocalin (NGAL), parathyroid hormone (PTH), albumin, and brain natriuretic peptide (BNP) were collected. These variables were added to the revised and combined (serum creatinine and cystatin C) Schwartz formulas, and the quadratic and combined quadratic formulas. We calculated the adjusted r-square (r2) in relation to iGFR and tested the improvement in variance explained by means of the likelihood ratio test. The combined Schwartz and the combined quadratic formulas yielded best results with an r2 of 0.676 and 0.730, respectively. The addition of BNP and PTH to the combined Schwartz and quadratic formulas improved the variance slightly. NGAL and albumin failed to improve the prediction of GFR further. These study results also confirm that the addition of cystatin C improves the performance of estimating GFR formulas, in particular the Schwartz formula.Conclusion: The addition of serum NGAL, BNP, PTH, and albumin to the combined Schwartz and quadratic formulas for estimating GFR did not improve GFR prediction in our population. What is Known:• Estimating glomerular filtration rate (GFR) formulas include serum creatinine and/or cystatin C but lack precision when compared to measured GFR.• The serum concentrations of some biological parameters such as neutrophil gelatinase-associated lipocalin (NGAL), parathyroid hormone (PTH), albumin, and brain natriuretic peptide (BNP) vary with the level of renal function. What is New:• The addition of BNP and PTH to the combined quadratic formula improved its performance only slightly. NGAL and albumin failed to improve the prediction of GFR further.

Major Factors

Chronic kidney disease defined by an estimated glomerular filtration rate of less than 60 mL/min or the presence of albuminuria is present in about 10% of the European populations. The risk increases with age, arterial hypertension, and diabetes. Both aspects—reduced estimated glomerular filtration rate, and albuminuria—are major factors associated with the progression of renal failure, cardiovascular events, and all-cause mortality. Patients on dialysis have a 10- to 20-fold increase in the cardiovascular event rate. Furthermore, heart failure and sudden cardiac death are associated with the severity of renal failure.

The aim of this chapter is to provide nurses with the knowledge to be able to assess, manage, and care for people with the renal disorders chronic kidney disease (CKD) and acute kidney injury (AKI) in an evidence-based and person-centred way. In recent years, AKI has replaced the term ‘acute renal failure’. The chapter will provide a comprehensive overview of the causes, risk factors, and impact of CKD and AKI, before exploring best practice to deliver care, as well as to prevent further progression of these conditions. Nursing assessments and priorities are highlighted throughout, and further nursing management of some of the symptoms and common health problems associated with CKD and AKI can be found in Chapters 6, 9, 15, and 19, respectively. Chronic kidney disease (CKD) is the gradual and usually permanent loss of some kidney function over time (Department of Health, 2007). In CKD, the damage and decline in renal function usually occurs over years, and in early stages can go undetected (Department of Health, 2005a). CKD has rapidly moved up the healthcare agenda in recent years, primarily because of the links with cardiovascular risk, and with a shift in focus away from the treatment of established renal failure towards the detection and prevention of CKD in primary care (O’Donohue, 2009). Glomerular filtration rate (GFR) is an indicator of renal function and is the rate at which blood flows through, and is ‘filtered’ by, the kidney; a normal GFR is approximately 125 ml/min. CKD is classified into five stages according to an estimated glomerular filtration rate (eGFR) and, in the milder stages, further evidence of renal damage such as proteinuria and haematuria. This classification holds regardless of the underlying cause of kidney damage. The understanding of GFR is pivotal to caring for patients with renal disorders. Monitoring, management, and referral of the patient in the earlier stages of CKD became much clearer following the publication of the National Clinical Guidelines for the Management of Adults with Chronic Kidney Disease in Primary and Secondary Care (NICE, 2008a). Many people with stage 3 CKD, unless they have proteinuria, diabetes, or other comorbidity such as cardiovascular disease, have a good prognosis and can be managed in primary care (Andrews, 2008).

Background: Neutrophil gelatinase-associated lipocalin (NGAL) is best known clinically as a novel and early marker of acute kidney injury. Renal dysfunction portends significant risk in patients admitted to coronary care units (CCUs). Thus, a sensitive marker of renal injury might also help to risk stratify patients hospitalized to CCUs. We prospectively investigated the prognostic value of a combination of serum NGAL and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels on admission for mortality in patients hospitalized to CCUs. Methods: We measured serum NGAL and NT-proBNP levels on admission in 974 consecutive patients hospitalized to CCUs. Among these patients, heart failure was present in 55%, and acute coronary syndrome in 40%. Results: Serum NGAL levels significantly correlated with NT-proBNP levels (r = 0.37, p <0.0001) and estimated glomerular filtration rate (r = -0.68, p < 0.0001). During a mean follow-up period of 829 days after admission, there were 178 (18%) all-cause deaths including 145 cardiovascular deaths. Comparably, patients who died were older (median, 78 vs. 72 yrs, p < 0.0001), had higher levels of NGAL (102 vs. 55 ng/ml, p < 0.0001), NT-proBNP (4043 vs. 1250 pg/ml, p < 0.0001), D-dimer (2.6 vs. 1.1 μg/ml, p < 0.0001), and high-sensitive C-reactive protein (6.0 vs.2.0 mg/l, p < 0.0001), and displayed lower values of left ventricular ejection fraction (39 vs. 50 %, p < 0.0001) and estimated glomerular filtration rate (43 vs. 65 ml/min/1.73m 2 , p < 0.0001) than those who did not. In multivariate Cox regression analysis including 11 clinical and biochemical variables, tertiles of NGAL (p = 0.02) and NT-proBNP (p = 0.02) was independently associated with all-cause deaths. The combination of NGAL and NT-proBNP tertiles were associated with increased all-cause mortality rates ( Figure ). Conclusion: The combined assessment of NGAL and NT-proBNP levels on admission may be useful for evaluating the risk of mortality in patients admitted to CCUs.

Esa Therapy

Serum soluble Fas (sFas) levels are associated with erythropoietin (Epo) hyporesponsiveness in patients with chronic kidney disease (CKD). Whether sFas could predict the need for erythropoiesis-stimulating agent (ESA) usage and its influence in erythropoiesis remain unclear. We evaluated the relation between sFas and ESA therapy in patients with CKD with anemia and its effect on erythropoiesis in vitro. First, we performed a retrospective cohort study with 77 anemic patients with nondialysis CKD. We performed in vitro experiments to investigate whether sFas could interfere with the behavior of hematopoietic stem cells (HSCs). HSCs were isolated from umbilical cord blood and incubated with recombinant sFas protein in a dose-dependent manner. Serum sFas positively correlated with Epo levels ( r = 0.30, P = 0.001) but negatively with hemoglobin ( r = −0.55, P < 0.001) and glomerular filtration rate ( r = −0.58, P < 0.001) in patients with CKD at baseline. Elevated sFas serum levels (4,316 ± 897 vs. 2,776 ± 749, P < 0.001) with lower estimated glomerular filtration rate (26.2 ± 10.1 vs. 33.5 ± 14.3, P = 0.01) and reduced hemoglobin concentration (11.1 ± 0.9 vs. 12.5 ± 1.2, P < 0.001) were identified in patients who required ESA therapy compared with patients with non-ESA. Afterward, we detected that the sFas level was slight correlated with a necessity of ESA therapy in patients with nondialysis CKD and anemia. In vitro assays demonstrated that the erythroid progenitor cell frequency negatively correlated with sFas concentration ( r = −0.72, P < 0.001). There was decreased erythroid colony formation in vitro when CD34+ HSCs were incubated with a higher concentration of sFas protein (1.56 ± 0.29, 4.33 ± 0.53, P < 0.001). Our findings suggest that sFas is a potential predictor for ESA therapy in patients with nondialysis CKD and that elevated sFas could affect erythropoiesis in vitro.
