AIM This study was performed to test the hypothesis that urinary levels of L-carnitine and its derivatives are enhanced in children and adolescents with hypertension and also check if analyzed parameters may serve as early markers of subclinical renal damage. METHODS The study included 112 children and adolescents (67 males and 45 females) aged median(More)
BACKGROUND The study was undertaken to develop a potential new markers for distinguishing minimal change nephrotic syndrome (MCNS) and focal segmental glomerulosclerosis (FSGS) in children. We hypothesized that matrix metalloproteinase-9/neutrophil gelatinase-associated lipocalin (MMP-9/NGAL) is a better marker of focal sclerosis in the glomerulus then(More)
UNLABELLED The purpose of this work was to investigate if in adolescents with hyperuricemia serum levels of asymmetric and symmetric dimethylarginine (ADMA, SDMA) are increased and if their levels correlate with serum uric acid (UA). PATIENTS AND METHODS The study group consisted of 58 hyperuricemic patients aged median 16.15 Q1-Q3 (14-17). The reference(More)
OBJECTIVE To assess functional day-time bladder capacity (DBC) and urine osmolality in children with primary monosymptomatic nocturnal enuresis (PMNE) according to age and sex. MATERIAL AND METHODS A total of 263 children with PMNE were divided into two groups: Group I, 160 children (63 girls, 97 boys) aged 5-9 years (mean age 7.14+/-1.47 years); and(More)
BACKGROUND Impairment in the functions of the lower urinary tract can be the cause of recurrent urinary tract infections (UTI) and vesicoureteral reflux (VUR) in children. The purpose of our research was to evaluate the frequency of occurrence of bladder instability in children with UTI. MATERIAL/METHODS The research involved 114 children (21 boys, 93(More)
Oxalate homeostasis is a derivative of absorption and transportation in the digestive system and renal/intestinal excretion of oxalate. The objective of this cross-sectional study was to determine normative values of plasma oxalate in relation to age, gender, and body size. A group of 1,260 healthy Caucasian children and adolescents aged 3 months to 18(More)
OBJECTIVE Myelomeningocele is the most common physically disabling birth defect in humans. It is caused by the failure of the neural tube to close and is most common in the lumbosacral area. Because of associated neurogenic bladder dysfunction, children with myelomeningocele have an increased risk of urinary tract infections and, ultimately, of kidney(More)
Idiopathic hypercalciuria is the most important predisposing risk factor for calcium oxalate (CaOx) renal stone formation. We assessed the associations between spontaneous CaOx crystallization based on the Bonn Risk Index (BRI), urinary pH, calciuria, oxaluria, and citraturia in 140 Caucasian patients with hypercalciuria, aged 4–17 years, and compared the(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)
UNLABELLED Hyperhomocysteinemia is independent risk factor of cardiovascular diseases. Similarly to nephrotic syndrome (NS) predisposes to vein thrombosis. THE AIM OF THE STUDY To evaluate serum and urinary total homocysteine (stHcy and utHcy) levels in children with the symptoms of SN, and to determine a correlation between its concentration and some(More)
