To determine outcomes in relation to duration of maintenance therapy in patients with granulomatosis with polyangiitis (Wegener's) (GPA), we conducted a retrospective chart review of patients with GPA seen at a single vasculitis center from 1992 to 2010. All patients achieved remission defined by a Birmingham Vasculitis Activity Score for Wegener(More)
Glomerulonephritis (GN) is an important cause of morbidity and mortality in patients of all ages throughout the world. Because these disorders are relatively rare, it is difficult to perform randomized clinical trials to define optimal treatment for many of the specific glomerulopathies. In the absence of high-grade evidence to guide the care of glomerular(More)
Wegener's granulomatosis is a complex multisystem disease that can be associated with morbidity and mortality. The introduction of cyclophosphamide and glucocorticoids brought about the potential for long-term survival and provided the opportunity and impetus to explore treatment options that can reduce the toxicity of therapy and lessen the likelihood of(More)
INTRODUCTION Previous studies suggest a role for eotaxin-3, TARC/CCL17 and IgG4 in newly-diagnosed patients with eosinophilic granulomatosis with polyangiitis (EGPA, Churg-Strauss) with highly active disease. The role of these biomarkers in relapsing disease is unclear. METHODS Serum levels of TARC/CCL17, eotaxin-3, IgG4, and IgG4/IgG ratio were(More)
The endothelial-specific Angiopoietin-Tie2 ligand-receptor system is an important regulator of endothelial activation. Binding of angiopoietin-2 (Ang-2) to Tie2 receptor renders the endothelial barrier responsive to pro-inflammatory cytokines. We previously showed that circulating Ang-2 correlated with disease severity in a small cohort of critically ill(More)
Granulomatosis with polyangiitis (formerly Wegener's) (GPA) and microscopic polyangiitis (MPA) share many clinical and pathological features, including antineutrophil cytoplasmic antibodies (ANCA) directed against either proteinase 3 (PR3) or myeloperoxidase (MPO). These two " ANCA-associated " vasculitides (AAV) are associated with a high mortality in(More)
