Rituximab (RTX) has recently showed promising results in the treatment of steroid-dependent idiopathic nephrotic syndrome (SDNS). This was a retrospective multicenter study of 18 children treated with RTX for SDNS, with a mean follow-up of 3.2 years. RTX was introduced because of side effects or relapses during therapy with immunosuppressive agents. The(More)
BACKGROUND It has been demonstrated that alkylating agents such as cyclophosphamide (CYP) are effective in reducing the risk of relapse in frequently relapsing (FRNS) and steroid-dependent nephrotic syndrome (SDNS). Little is known about prognostic factors in SDNS and FRNS treated by CYP. The objectives of this study are to determine long-term outcomes and(More)
Data on long-term outcomes after pediatric renal transplantation (Tx) are still limited. We report on a 20-year single-center experience. Medical charts of all consecutive pediatric Tx performed between 1987 and 2007 were reviewed. Data of patients who had been transferred to adult units were extracted from the French databases of renal replacement(More)
Haemolytic uremic syndrome (HUS) is characterized by thrombotic microangiopathy with acute renal failure, haemolytic anaemia with schizocytes and thrombocytopenia. Typical forms (D(+) HUS) are caused by gastrointestinal infection with Escherichia coli species producing verotoxines (or Shiga toxins, STEC). It is estimated that 5-8 % of infected individuals(More)
The management of tubulopathies after renal transplantation (RTx) may require high doses of sodium and bicarbonate, reducing the quality of life and therapeutic compliance of the patient. Some studies on adult patients have highlighted the benefits of fludrocortisone (fludro) in the treatment of severe tubulopathies. This study was a retrospective review of(More)

Cystinosis is a multisystemic autosomal recessive disorder characterized by an intra-lysosomal accumulation of cystine. It is due to a defect of cystine transport through the membrane of the lysosome. The classical infantile form is characterized by a proximal tubulopathy, corneal cystine crystals and progressive renal failure, leading to end stage renal(More)
FS is an inherited disease characterized by male pseudohermaphroditism and glomerular involvement leading to end-stage renal disease during adolescence or early adulthood (J Pediatr 1964:64:740). The FS phenotype in 46,XY patients consists of female external genitalia, gonadal dysgenesis, high risk of gonadoblastoma, and development of renal failure in the(More)
INTRODUCTION Preterm neonates are particularly at risk of vitamin D (25-D) deficiency. To prevent rickets and osteopenia in this population, international guidelines vary between 800 and 1000IU per day of vitamin D in Europe and recommend 400IU per day in the USA. Target levels of circulating 25-D are not well identified, with the lower target level(More)
Observation of stunted growth in children usually leads the general practitioner to refer the patient to endocrinologists or gastroenterologists. In most cases, after a complementary check-up, the diagnosis is made and treatment is initiated. However, certain cases remain undiagnosed, particularly renal etiologies, such as proximal tubulopathy. The urine(More)
