BACKGROUND Rituximab could be an effective treatment for childhood-onset, complicated, frequently relapsing nephrotic syndrome (FRNS) and steroid-dependent nephrotic syndrome (SDNS). We investigated the efficacy and safety of rituximab in patients with high disease activity. METHODS We did a multicentre, double-blind, randomised, placebo-controlled trial(More)
We conducted a multicenter prospective trial to evaluate the efficacy, safety and pharmacokinetics of a single dose of rituximab (375 mg/m(2) body surface area) for the treatment of children with refractory steroid-dependent nephrotic syndrome (SDNS). All patients (n = 12) were able to discontinue steroids at a median of 74 days after treatment. The(More)
A five-yr-old boy developed chronic liver failure and ESKD because of CHF and juvenile NPHP. He underwent sequential liver and kidney transplantation with a compatible blood type from his father, at five yr, seven months and five yr, 11 months old, respectively. Because the patient was not in ESKD, we initially performed LDLT because of significant portal(More)
Rituximab (RTX) has a significant steroid-sparing effect in children with steroid-dependent nephrotic syndrome (SDNS). However, patients are likely to relapse with the recovery of CD20+ cells. We conducted a small prospective cohort study with a historical control to evaluate the effect of RTX infusion followed by mycophenolate mofetil (MMF) as a(More)
Rituximab (RTX) has been successfully used as a rescue therapy in children with steroid-dependent nephrotic syndrome (SDNS). However, little is known regarding maintenance therapy after a successful response to RTX in such patients. The efficacy and safety of a single RTX infusion (375 mg/m(2)) were assessed in ten patients who had persistent SDNS(More)
BACKGROUND Calcineurin inhibitors (CIs) with/without intravenous methylprednisolone pulse therapy (MPT) constitute the standard treatment for childhood-onset, steroid-resistant nephrotic syndrome (SRNS). However, some patients fail to achieve remission. We treated SRNS patients resistant to CIs and MPT with additional rituximab combined with MPT and(More)
BACKGROUND The prognosis of children with severe IgA nephropathy showing diffuse mesangial proliferation is poor. However, the prognosis can be improved by combination therapy (prednisolone + azathioprine or mizoribine + warfarin + dipyridamole) or prednisolone alone over a 2-year period, and disappearance of glomerular IgA deposits is often observed.(More)
BACKGROUND AND OBJECTIVES Children with IgA nephropathy showing diffuse (>80%) mesangial proliferation are at high risk for end-stage renal failure (ESRF). A previous controlled trial showed that combination therapy consisting of prednisolone, azathioprine, heparin-warfarin, and dipyridamole early in the course of disease reduces immunologic renal injury(More)
CONTEXT Our understanding of inherited salt-losing tubulopathies has improved with recent advances in molecular genetics. However, the terminology of Bartter syndrome and Gitelman syndrome does not always accurately reflect their pathophysiological basis or clinical presentation, and some patients are difficult to diagnose from their clinical presentations.(More)
The aim of this study was to establish the efficacy and safety of rituximab in refractory nephrotic syndrome (NS). Members of the International Paediatric Nephrology Association were asked to retrospectively fill in a questionnaire with details on the use of rituximab in their centres. We divided the data into three groups: group 1, patients with(More)
