Congenital obstructive nephropathy is the primary cause of chronic renal failure in children. Rapid diagnosis and initiation of the treatment are vital to preserve function and/or to slow down renal injury. The aim of our study was to determine whether urinary (u) kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) may be(More)
BACKGROUND Although autistic spectrum disorders (ASD) are a strongly genetic condition certain metabolic disturbances may contribute to clinical features. Metabolism of oxalate in children with ASD has not yet been studied. AIM The objective was to determine oxalate levels in plasma and urine in autistic children in relation to other urinary parameters.(More)
BACKGROUND Enhanced platelet reactivity may play a significant role in the hypercoagulable state of nephrotic syndrome (NS). Thrombocytosis with platelet aggregation cause the release of some cytokines, among them interleukin-7 (IL-7). The aim of the study was to evaluate serum IL-7 levels in children with the symptoms of NS and to determine a correlation(More)
The aim of the study was to investigate (1) whether there are any changes in release of platelet-derived growth factor AA (PDGF AA) in children with nephrotic syndrome without clinical thromboembolic symptoms 2; (2) whether serum PDGF AA correlates with the platelet count (PLT) and platelet indices; (3) whether prednisone therapy affects the serum PDGF AA(More)
PURPOSE The Bonn Risk Index has been used to evaluate the risk of urinary calcium oxalate stone formation. According to the original method, risk should be determined based on a 200 ml urine sample taken from a 24-hour collection. We evaluated whether the Bonn Risk Index can also be effectively determined in small urine samples. MATERIALS AND METHODS We(More)
Bonn Risk Index (BRI) is being used for the assessment of urinary calcium oxalate (CaOx) crystallization. There are no published data regarding BRI during growth. The objective of this study was to establish age- and sex-dependent BRI values in healthy children and adolescents. A total of 1,050 Caucasian subjects aged 3-18 years (525 males, 525 females)(More)
Published data on the association between calcium oxalate (CaOx) crystallization and kidney stone disease in children are scarce. The aims of this study were to determine CaOx crystallization using the Bonn Risk Index (BRI) in children with urolithiasis in comparison to healthy controls, to evaluate the relationships between BRI and urinary parameters, such(More)
The aim of work was to investigate whether serum and urinary neutrophil gelatinase-associated lipocalin(sNGAL and uNGAL, respectively) are potential biomarkers of early cyclosporine A (CsA) nephrotoxicity in steroid-dependent nephrotic children (SDNS). The study group (I) consisted of 19 children with SDNS aged 9.46+/-5.52 years treated with CsA. The(More)
The purpose of the study was to investigate serum uric acid (SUA), high-sensitivity C-reactive protein (hs-CRP) and mean platelet volume (MPV) in pre-hypertensive (PH) and hypertensive (HT) children and adolescents. The study group consisted of 80 patients aged 10-19 years subdivided into PH and HT groups according to mean daytime or night-time systolic or(More)
PURPOSE The Bonn Risk Index has been used to evaluate the risk of urinary calcium oxalate stone formation. According to the original method, risk should be determined based on 24-hour urine collection. We studied whether the Bonn Risk Index could be measured in spot urine samples and which part of the day is most suitable for this purpose. MATERIALS AND(More)
