BACKGROUND: Cardiovascular disease is the second-most common cause of death in pediatric renal transplant recipients. The aim of this study was to evaluate subclinical cardiovascular target organ damage defined as the presence of arterio- and atherosclerotic lesions and cardiac remodeling and to analyze contributing risk factors in a large cohort of children after renal transplantation (RT). METHODS: A total of 109 children aged 13.1 ± 3.3 years who had undergone RT at one of three German transplant centers were enrolled in this study...

BACKGROUND: The search for risk factors for chronic kidney disease in children with focal segmental glomerulosclerosis (FSGS) is important in defining prognosis and individualized treatment. This study preliminarily investigated whether CD44 immunostaining in glomerular parietal epithelial cells (PECs) is a prognostic marker in pediatric FSGS. METHODS: In this retrospective study, 26 patients with FSGS, biopsied from 1985 to 2010, were evaluated. Immunohistochemistry for CD44 was performed in all cases...

The dose to kidneys of newborns and 1-year old children was calculated using the MIRD methodology. In order to perform renal studies radiopharmaceutical like (99m)Tc-DTPA, (99m) Tc-MAG3 and (99m)Tc-DMSA are used. Here, besides the anatomic and structure information of kidneys another data are provided in benefit of patient, however during the radioisotope decay emitted radiations delivers, totally or partially, their energy. Therefore is important to estimate the internal radiation dose of the organs. The largest dose to kidneys comes from the self-dose and it is due to the charged particles emitted during (99m)Tc decay...

The aim of the study was to develop a population PK model for teicoplanin across childhood age ranges to be used as Bayesian prior information in the constructed software for individualized therapy. We developed a non-parametric population model fitted to PK data from neonates, infants and older children. We then implemented it in the BestDose multiple-model Bayesian adaptive control algorithm to show its clinical utility. It was used to predict the required dosages to achieve teicoplanin optimal pre-dose targets (15 mg/L) from day 3 of therapy...

Antineoplastic drugs' clinical use can be limited by different drug-induced toxicities. Of these, renal dysfunction may be one of the most troublesome in that it can be cumulative and in general is only partially reversible with the discontinuation of the treatment. Renal toxicity may be manifested as a reduction of the glomerular filtration rate, electrolyte imbalances, or frank renal failure. Careful assessment of renal function has to be performed taking into account that the impairment of the renal function is initially silent and only later may be clinically dramatic...

Fourteen children have undergone liver transplantation for hereditary tyrosinaemia type 1 (HT1) at Birmingham Children's hospital (BCH) since 1989; six were treated prior to the availability of Nitisinone in 1993 and eight in the post Nitisinone era. Prior to 1993 essentially all children with HT1 were referred for transplantation. In the Nitisinone era only those with unresponsive liver failure or suspected malignancy were considered for transplantation. Those who were treated pre-emptively following newborn screening have no evidence of liver disease and none have required transplantation...

OBJECTIVE: Prenatal management of male fetuses with suspected posterior urethral valves depends on reliable markers for postnatal long-term renal function. Whether ultrasound parameters, including the presence or absence of oligohydramnios, are reliable remains the subject of debate. We decided to evaluate the reliability of quantity of amniotic fluid to predict postnatal renal function using decision curve analysis (DCA), a method for evaluating the clinical utility of a diagnostic test...

Factor H autoantibodies can impair complement regulation, resulting in atypical hemolytic uremic syndrome, predominantly in childhood. There are no trials investigating treatment, and clinical practice is only informed by retrospective cohort analysis. Here we examined 175 children presenting with atypical hemolytic uremic syndrome in the United Kingdom and Ireland for factor H autoantibodies that included 17 children with titers above the international standard. Of the 17, seven had a concomitant rare genetic variant in a gene encoding a complement pathway component or regulator...

Prevalence, clinicopathological features, and outcome of childhood idiopathic steroid-resistant nephrotic syndrome (ISRNS) vary in different countries. We report on these parameters in a single center in Khartoum. We retrospectively reviewed all the records of children with idiopathic nephrotic syndrome (INS) followed up in the pediatric renal unit, Soba Hospital, Khartoum between 2001 and 2012. ISRNS was defined as no remission within four weeks of daily prednisolone at a dose of 60 mg/m2. In 430 children with INS 130 (28%) had SRNS with a mean age of 7...

The experience using anidulafungin for the treatment of invasive fungal infections in pediatrics is limited. In this article, we describe our experience in 55 children. Anidulafungin was administered intravenously at a loading dose of 3 mg/kg once daily, followed by 1.5 mg/kg every 24 hours over a mean period of 14 days (range: 7-22 days). Patients' median age was 114 months old (interquartile range: 32-168 months old). All patients had underlying diseases. Among patients with bone marrow transplant, the difference in white blood cell count, transaminase levels, and renal function at baseline and at the end of anidulafungin administration was not significant...

Wilms tumour (WT) is the most common paediatric kidney cancer and affects approximately one in 10 000 children. The tumour is associated with undifferentiated embryonic lesions called nephrogenic rests (NRs) or, when diffuse, nephroblastomatosis. WT or NRs can occur in both kidneys, termed bilateral disease, found in only 5-8% of cases. Management of bilateral WT presents a major clinical challenge in terms of maximising survival, preserving renal function and understanding underlying genetic risk. In this review, we compile clinical data from 545 published cases of bilateral WT and discuss recent progress in understanding the molecular basis of bilateral WT and its associated precursor NRs in the context of the latest radiological, surgical and epidemiological features...

BACKGROUND: If untreated, paediatric neurogenic bladder can cause renal failure and urinary incontinence. It is usually caused by neural tube defects such as myelomeningocele. Children with a neurogenic bladder should be monitored from birth and management should aim to preserve renal function and achieve social continence. This article outlines the management options appropriate for these children in resource-poor settings. ASSESSMENT: In most low- and middle-income countries, a general lack of awareness of the neurological effects on the urinary tract results in late presentation, usually with urological complications even when spina bifida is diagnosed early...

Glutaric aciduria type 1 (GA1) is caused by deficiency of the mitochondrial matrix enzyme glutaryl-CoA dehydrogenase (GCDH), leading to accumulation of glutaric acid (GA) and 3-hydroxyglutaric acid (3OHGA) in tissues and body fluids. During catabolic crises, GA1 patients are prone to the development of striatal necrosis and a subsequent irreversible movement disorder during a time window of vulnerability in early infancy. Thus, GA1 had been considered a pure "cerebral organic aciduria" in the past. Single case reports have indicated the occurrence of acute renal dysfunction in children affected by GA1...

Myelodysplasia includes a group of developmental anomalies resulting from defects that occur during neural tube closure. Urological morbidity in patients with myelodysplasia is significant and if not treated appropriately in a timely manner can potentially lead to progressive renal failure, requiring dialysis or transplantation. We report the case of a 13-year old girl with neurogenic bladder who presented chronic renal failure secondary to lipomyelomeningocele with retethering of cord. She was managed with urinary indwelling catheterization until optimization of renal function and then underwent detethering of cord with excision and repair of residual lipomeningomyelocele...
