BACKGROUND Cyclophosphamide and glucocorticoids have been the cornerstone of remission-induction therapy for severe antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis for 40 years. Uncontrolled studies suggest that rituximab is effective and may be safer than a cyclophosphamide-based regimen. METHODS We conducted a multicenter, randomized,(More)
OBJECTIVE To evaluate the efficacy and safety of rituximab in a randomized, double-blind, placebo-controlled phase III trial in patients with lupus nephritis treated concomitantly with mycophenolate mofetil (MMF) and corticosteroids. METHODS Patients (n = 144) with class III or class IV lupus nephritis were randomized 1:1 to receive rituximab (1,000 mg)(More)
Copyright © 2012 Massachusetts Medical Society. Membranoproliferative glomerulonephritis (MPGN), also termed mesangiocapillary glomerulonephritis, is diagnosed on the basis of a glomerular-injury pattern that is common to a heterogeneous group of diseases. MPGN accounts for approximately 7 to 10% of all cases of biopsy-confirmed glomerulonephritis1-4 and(More)
IgA nephropathy is the most common glomerular disease worldwide, yet there is no international consensus for its pathological or clinical classification. Here a new classification for IgA nephropathy is presented by an international consensus working group. The goal of this new system was to identify specific pathological features that more accurately(More)
Transplant renal artery stenosis (TRAS) is an increasingly recognized complication of renal transplantation, with a reported incidence of between 1% and 23%. The clinical features include refractory hypertension, new-onset hypertension, allograft dysfunction, and the presence of a bruit over the graft. In this report, we describe the investigation and(More)
BACKGROUND & OBJECTIVES Renal pathology and clinical outcomes in patients with primary Sjögren's syndrome (pSS) who underwent kidney biopsy (KB) because of renal impairment are reported. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Twenty-four of 7276 patients with pSS underwent KB over 40 years. Patient cases were reviewed by a renal pathologist,(More)
RATIONALE Standard therapy for Wegener's granulomatosis is fraught with substantial toxicity and not always effective. B lymphocytes have been implicated in the pathogenesis of Wegener's granulomatosis. Their depletion has been proposed as salvage therapy for refractory disease. Earlier encouraging reports are confounded by concomitant immunosuppressive(More)
Membranous nephropathy (MN) is considered the most common cause of nephrotic syndrome in white adults, but recent studies have shown an increasing incidence of focal segmental glomerulosclerosis (FSGS). These studies are difficult to interpret because the majority of cases came from urban tertiary referral centers. For validating these findings in the(More)
OBJECTIVE This study was conducted to evaluate the efficacy and safety of repeated and prolonged B cell depletion with rituximab (RTX) for the maintenance of long-term remission in patients with chronic relapsing granulomatosis with polyangiitis (Wegener's) (GPA). METHODS We conducted a single-center observational study of all patients with chronic(More)
C3 glomerulopathy is a recently introduced pathological entity whose original definition was glomerular pathology characterized by C3 accumulation with absent or scanty immunoglobulin deposition. In August 2012, an invited group of experts (comprising the authors of this document) in renal pathology, nephrology, complement biology, and complement(More)
