BACKGROUND Cardiosurgical operations in cardiopulmonary bypass (CPB) constitute a risk of acute kidney injury (AKI). OBJECTIVES The aim of the study was an assessment of AKI risk in children within the first 24 hours after CPB cardiac surgery, evaluating serum interleukin 6 (sIL6). MATERIAL AND METHODS The study included 47 children with congenital(More)
Obesity is a well-known risk factor for arterial hypertension. The aim of this study was to analyze which surrogate marker of adiposity, i.e., body mass index (BMI) or fat mass (FM), as measured by bioimpedance analysis (BIA), best correlated with blood pressure in healthy children. Body weight, height, and casual blood pressure (BP) were measured in 193(More)
BACKGROUND/AIMS The recent improvements of management of patients in pediatric intensive care units (PICU) are associated with improved outcome. However, this decrease in mortality is associated with an increased number of children with acute kidney injury (AKI), especially in patients with multiorgan failure. METHODS The report presents a retrospective(More)
BACKGROUND The purpose of the study was to examine the relationship between urea and conjugated bilirubin kinetics during extracorporeal liver support (ELS) therapy and to determine the dose of therapy for urea and conjugated bilirubin as markers for water-soluble and protein-bound solutes, respectively. METHODS Kinetics of urea and bilirubin were(More)
A comparison of accuracy between electrical bioimpedance analysis (BIA) and body mass index (BMI) for fat mass evaluation in children was the aim of the study. One-hundred and ninety three healthy children (90 females, 103 males) were enrolled. The mean age of the studied population was 11.8 years (+/- 2.2), mean weight equalled to 42.6 (+/- 12.8) kg and(More)
PURPOSE We assessed the reliability of calculating eGFR in children as compared to the iohexol disappearance test (GFR-I), which was performed 417 times in 353 children aged 2 and more. MATERIAL/METHODS eGFR was estimated with equations based on serum creatinine: Schwartz (1: eGFR-Scr), Cockroft-Gault (2: eGFR-CG) and MDRD (3: eGFR-MDRD), and on(More)
BACKGROUND/AIM As continuous renal replacement therapy (CRRT) has emerged as a standard therapy in pediatric intensive care units (PICU), many related issues that may have an impact on circuit survival have gained in importance. Objective of the study was an evaluation of factors associated with circuit survival, including anticoagulation (ACG). METHODS(More)
Glomerular filtration rate (GFR) estimation is very important for evaluation of kidney function. Its calculation is based upon a 24 hour urine collection and serum creatinine concentration values or on the basis of developed for this purpose numerous formulas with special attention dedicated to the abbreviated MDRD formula and Cockcroft-Gault formulas for(More)
AIM Estimation of eGFR in children with normal kidney function using the Schwartz equations results in underestimating real GFR. MATERIALS AND METHODS We propose modification of three Schwartz equations - two based on creatinine concentration (eGFRScrBS bedside) and (eGFRScr) and one 3-marker based on creatinine, urea and cystatin C concentrations(More)
Biological samples can be investigated with atomic force microscopy (AFM) in either of two imaging modes: contact mode or tapping mode. Applications of fluid tapping mode AFM in biology and medical sciences are constantly growing and the data obtained with this technique are improving, especially in terms of resolution. Even dynamic processes can be(More)
