Incidence and causes of urolithiasis in children between 0-2 years.

Background: Urolithiasis (UL) is a common problem in pediatric nephrology practice. About 9-23% of all pediatric UL cases consist of patients under 1 years old. The aim of the present study was to determine etiologic causes, clinical features and short term prognosis of urolithiasis in the first two years of life.

Association of mannose binding lectin codon 54 polymorphism with predisposition to Henoch-Schönlein purpura in childhood.

Aim: Immune and inflammatory response activation is a common feature of systemic vasculitis. There is a protein called mannose binding lectin (MBL) that was reported to play an important role in innate immunity. MBL polymorphisms in the MBL gene cause predisposition to infectious and autoimmune diseases.

Management of anemia in children receiving chronic peritoneal dialysis.

Little information exists regarding the efficacy, modifiers, and outcomes of anemia management in children with CKD or ESRD. We assessed practices, effectors, and outcomes of anemia management in 1394 pediatric patients undergoing peritoneal dialysis (PD) who were prospectively followed in 30 countries. We noted that 25% of patients had hemoglobin levels below target (<10 g/dl or <9.

Involution of multicystic dysplastic kidney: is it predictable?

Objective: To evaluate the clinical course of multicystic dysplastic kidney (MCDK) and to reveal any criteria indicating spontaneous involution.

Material Methods: Hospital records of patients with MCDK followed in two different institutions in 1994-2009 were reviewed and data were analyzed regarding involution.

Results: Records of 96 patients were reviewed, of whom 46 were diagnosed antenatally and followed for more than 1 year.

The bone and mineral disorder of children undergoing chronic peritoneal dialysis.

The mineral and bone disorder of chronic kidney disease remains a challenging complication in pediatric end-stage renal disease. Here, we assessed symptoms, risk factors and management of this disorder in 890 children and adolescents from 24 countries reported to the International Pediatric Peritoneal Dialysis Network Registry. Signs of this disease were most common in North American patients.

Etiology and outcome of acute kidney injury in children.

The aim of this prospective, multicenter study was to define the etiology and clinical features of acute kidney injury (AKI) in a pediatric patient cohort and to determine prognostic factors. Pediatric-modified RIFLE (pRIFLE) criteria were used to classify AKI. The patient cohort comprised 472 pediatric patients (264 males, 208 females), of whom 32.

Contractility reserve in children undergoing dialysis by dobutamine stress echocardiography.

Left ventricular hypertrophy is an adaptive mechanism in children undergoing chronic dialysis to improve contractility at rest. The aim of this study was to determine the left ventricular performance and contractility reserve by "dobutamine stress echocardiography" in children undergoing chronic dialysis. Thirty-five children undergoing dialysis and 24 healthy subjects were enrolled in this prospective study.

Low-density lipoprotein apheresis by membrane differential filtration (cascade filtration) via arteriovenous fistula performed in children with familial hypercholesterolemia.

Membrane differential filtration (cascade filtration) is an apheresis technique by which atherogenic lipoproteins can be eliminated from plasma on the basis of particle size. In this study, we aim to discuss the efficacy of low-density lipoprotein (LDL) apheresis performed by providing alternative vascular routes in two siblings with familial hypercholesterolemia who did not respond to medical treatment and diet. Of the two siblings, one was nine years old and the other one was three-and-a-half years old.

Low density lipoprotein apheresis in pediatric patients with homozygous familial hypercholesterolemia.

The aim of the present study is to clarify the low density lipoprotein apheresis procedure for pediatric patients with homozygous familial hypercholesterolemia (FH) in terms of efficacy, adverse effects and difficulties. The follow-up was carried out using an open, prospective uncontrolled clinical design. Data were collected from 10 patients (with an average age of 8.

The metabolic etiology of urolithiasis in Turkish children.

Pediatric urolithiasis is an endemic disease, especially in certain developing regions of the world, such as the Far East, and to a certain extent the Middle East and Turkey. The aim of the study is to determine the metabolic etiology and the prevalence of formation of urinary calculi in Turkish pediatric patients with urolithiasis. Seventy-two pediatric patients diagnosed as having urolithiasis were studied from 1999-2005 in Dr.

NPHS2 (podicin) mutations in Turkish children with idiopathic nephrotic syndrome.

The podocin (NPHS2) gene encodes podocin protein, which has an important role in glomerular ultrafiltration and controlling slit membrane permeability. The detection of an NPHS2 mutation affects the treatment plan for children with nephritic syndrome (NS). The frequency and spectrum of podocin mutations in the Turkish population have remained largely unknown.

Prophylactic calcium and vitamin D treatments in steroid-treated children with nephrotic syndrome.

Steroid treatment has several side effects, including the deterioration of the bone and mineral metabolism in children with nephrotic syndrome. This randomized prospective study was conducted to determine the effects and prophylactic role of calcium plus vitamin D treatment on bone and mineral metabolism in children receiving prednisolone treatment. 40 children (27 boys and 13 girls) with NS (18 new onset and 22 relapsing) were included in the study.

ACE gene insertion/deletion polymorphism in childhood idiopathic nephrotic syndrome.

The aim of this study was to determine the distribution of angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism, and its effects on clinical, laboratory, histological findings, treatment responses and progression to end-stage renal disease in childhood idiopathic nephrotic syndrome (NS). 227 children diagnosed with idiopathic NS were included in the study. Eighty-three of patients were steroid resistant and 77 of patients were focal segmental glomerulosclerosis.

Impact of haemodialysis on QTc dispersion in children.

Background: The purpose of the present paper was to investigate the corrected QT (QTc) interval and QTc dispersion value, and the impact of haemodialysis on these parameters in children with chronic renal failure.

Methods: Nineteen patients with chronic renal failure receiving haemodialysis were included in the present study. Electrocardiography (ECG), echocardiography and serum biochemistry were performed in all patients.

Effect of adventitial dissection in brachiobasilic arteriovenous fistulae opened in children as vascular access for hemodialysis on patency and maturation of fistulae.

Background: Recently, therapy of pediatric patients with chronic renal failure has been carried out using hemodialysis, peritoneal dialysis, or renal transplant. In this study, we prospectively investigated the role of adventitial dissection (performed on brachiobasilic arteriovenous fistulae in the antecubital area) in the patency rate, maturation, and early initiation of dialysis among pediatric cases undergoing chronic hemodialysis.

Methods: Thirty children (7 male and 23 females) were included in this study.
