Hemolytic uremic syndrome (HUS) is characterized by the triad of thrombocytopenia, microangiopathic hemolytic anemia, and acute renal failure. The non-Shiga toxin-associated HUS (atypical HUS [aHUS]) has been shown to be a disease of complement dysregulation. Mutations in the plasma complement regulators factor H and factor I and the widely expressed(More)
BACKGROUND The influence of hepatitis C virus (HCV) treatment on the course of HCV cryoglobulinemic membranoproliferative glomerulonephritis (MPGN) is controversial. METHODS Twenty-five patients with nephrotic-range proteinuria, mixed cryoglobulinemia, MPGN proved by renal biopsy, and HCV infection were studied for their response to antiviral treatment.(More)
BACKGROUND AND OBJECTIVES Renal infarction is an arterial vascular event that may cause irreversible damage to kidney tissues. This study describes the clinical characteristics of patients with renal infarction according to underlying mechanism of vascular injury. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This study retrospectively identified 94(More)
Plasma DNA that circulates mainly as mononucleosomes is a cell death marker. Its significance and prognostic value in cancer as compared to other tumour markers was investigated in 68 patients hospitalised for lung cancers. Prognostic values of the various studied parameters were evaluated using the Cox's model. The cellular origin of plasma DNA was further(More)
Microscopic polyangiitis (MPA) is a systemic small-vessel vasculitis primarily associated with necrotizing glomerulonephritis and pulmonary capillaritis. In this retrospective study of 29 patients with MPA and alveolar hemorrhage (AH), we characterized the pulmonary manifestations at presentation and assessed the short- and long-term outcome. AH was(More)
BACKGROUND Low-complement urticarial vasculitis is an uncommon condition associating urticaria, glomerulonephritis, obstructive ventilatory disorders, and anti-Ciq antibodies. CASE REPORT We report a case in a 34-year-old woman who developed urticaria with purpura, membranoproliferative glomerulonephritis (creatinine 238 mumol/l) and bronchial obstruction(More)
Levels of circulating DNA increase under treatment by an artificial kidney. Using a new assay, levels of plasma DNA are studied in 45 patients during 99 sessions of hemodialysis or hemofiltration. Before the session, plasma DNA levels are increased in 41/99 samples and, among them, in 18/24 samples collected from hepatitis B surface antigen carriers. During(More)
