BACKGROUND In patients with refractory steroid-sensitive nephrotic syndrome (SSNS), treatment with rituximab has shown encouraging results; however, long-term follow-up data are not available. METHODS We performed a retrospective analysis of 37 patients (25 boys) with steroid-dependent nephrotic syndrome who were treated with rituximab (375 mg/m(2) given(More)
BACKGROUND Chronic antibody-mediated rejection (CAMR) of renal allografts has recently been recognized as a defined nosologic entity. The outcome of CAMR is poor; there is no established treatment protocol for this condition. We therefore initiated a pilot study on treatment of CAMR with an antihumoral regimen consisting of high-dose intravenous(More)
Children with X-linked hypophosphatemic rickets (XLH) are prone to severe stunting. A multicenter mixed-longitudinal study was conducted to assess age-related stature, sitting height, arm and leg length in XLH patients on continuous treatment with phosphate and calcitriol. Mean standard deviation scores (SDS) for all body dimensions were markedly reduced(More)
Chronic antibody-mediated rejection (AMR) is the major cause of late renal allograft loss. There is, however, no established treatment for this condition. We report the results of a prospective pilot study on an antihumoral therapy (AHT) consisting of high-dose intravenous immunoglobulin G (IVIG) and rituximab in 20 paediatric renal transplant recipients.(More)
We report on a 2-year-old boy on automated peritoneal dialysis (PD) with a history of multiple hernias and dialysate leaks who developed pericardial effusion. Magnetic resonance imaging (MRI) demonstrated a peritoneo-pericardial fistula. Dialysis had to be discontinued, since head-down tilt reproducibly induced significant hypotension. In PD patients with(More)
Schimke-immuno-osseous dysplasia (SIOD) is a multisystem disorder with the following consistent clinical features: spondyloepiphyseal dysplasia with disproportional growth deficiency, nephrotic syndrome with focal and segmental glomerulosclerosis, and defective cellular immunity. Transitory ischemic attacks due to vaso-occlusive processes are complications(More)
Mutations in the NPHS2 gene encoding podocin are associated with steroid-resistant nephrotic syndrome (SRNS) in childhood. Patients usually present with focal segmental glomerulosclerosis (FSGS). It is unclear to what extent SRNS due to NPHS2 mutations predisposes to recurrence of proteinuria/FSGS after renal transplantation (RTx). A 4-year-old girl with(More)
PURPOSE OF REVIEW Tubulointerstitial nephritis and uveitis syndrome (TINU) is a specific form of intraocular inflammation (uveitis) combined with kidney disease that was first described in two patients by Dobrin et al. in 1975. Since then, approximately 200 more cases have been published. The cause of the disease is still unknown. A hypersensitivity(More)
BACKGROUND The epidemiology and morbidity of Epstein-Barr virus (EBV) infection in pediatric renal transplant recipients have been characterized insufficiently. METHODS In a prospective, multicenter study among 106 pediatric kidney allograft recipients aged 11.4 ± 5.9 years, we investigated the epidemiology of EBV infection and the relationship between(More)
Endothelial cell injury plays a key role in the pathogenesis of lupus nephritis (LN) and atherosclerosis. The aim of this study was to identify factors involved in the process of endothelial damage in children and adolescents with LN. We evaluated the relationship between plasma vascular endothelial growth factor (VEGF), its soluble receptors sVEGFR-1 and(More)
