Cholesterol crystal embolism, sometimes separately designated atheroembolism, is an increasing and still underdiagnosed cause of renal dysfunction antemortem in elderly patients. Renal cholesterol crystal embolization, also known as atheroembolic renal disease, is caused by showers of cholesterol crystals from an atherosclerotic aorta that occlude small(More)
OBJECTIVE To evaluate the efficacy and safety in the long term of a retreatment regimen with Rituximab (RTX) alone administered at clinical relapse in cryoglobulinemic vasculitis (CV). METHODS Thirty patients with severe HCV-related CV, previously enrolled in the multicentre Italian trial on RTX in the treatment of CV, were retrospectively evaluated after(More)
BACKGROUND Metabolic acidosis in haemodialysis (HD) patients increases whole body protein degradation while the correction of acidosis reduces it. However, the effects of the correction of acidosis on nutrition have not been clearly demonstrated. STUDY DESIGN In this study we have evaluated the effects of 3 months of correction of metabolic acidosis by(More)
BACKGROUND The effect of the adequacy of dialysis on the response to recombinant human erythropoietin (rHuEpo) therapy is still incompletely understood because of many confounding factors such as iron deficiency, biocompatibility of dialysis membranes, and dialysis modality that can interfere. METHODS We investigated the relationship between Kt/V and the(More)
BACKGROUND Metabolic acidosis contributes to renal osteodystrophy and together with hyperphosphatemia, hypocalcemia and altered vitamin D metabolism may result in increased levels of intact parathyroid hormone (iPTH) and metastatic calcifications. However, the impact of the correction of metabolic acidosis on iPTH levels and calcium-phosphate metabolism is(More)
OBJECTIVES To study the health-related quality of life (HRQOL) in severe cryoglobulinaemic vasculitis (CV) associated with hepatitis C virus infection (HCV) and to describe the effect of rituximab on HRQOL. METHODS HRQOL was evaluated with the Medical Outcomes Study Short Form 36 (SF-36). Health Survey questionnaire was submitted to 15 patients with(More)
OBJECTIVES To investigate the clinical and laboratory patterns of HCV-unrelated cryoglobulinaemic vasculitis (CV), and the factors influencing its outcome. METHODS Prospective study of all anti-HCV and HCV-RNA negative patients with CV who have been observed since January 2004 in 17 centres participating in the Italian Group for the Study of(More)
We present the first, probably autocton, case of abdominal angiostrongyliasis in Rio de Janeiro State. The patient presented initially with fever of unknown origin and severe eosinophilia developing acute abdomen due to small bowel perfuration, peritonitis, hepatic necrosis and sepsis. At the laparotomy a segment of small bowel was ressected and a liver(More)
