Plasma Exchange Shows Little Benefit in AAV Treatment, Meta-analysis Finds

Adding plasma exchange to immune-suppressing treatment does not significantly improve clinical outcomes in people with ANCA-associated vasculitis (AAV), a new meta-analysis indicates. The analysis, “The role of plasma exchange in antineutrophil cytoplasmic antibody-associated vasculitis: a meta-analysis,” was published in Clinical Rheumatology. AAV is characterized by…

AAV Carries High Healthcare Costs, Italian Study Finds

ANCA-associated vasculitis (AAV) carries high healthcare costs for therapies and hospitalizations to treat the disease itself and related infections, a study in Italy has found. The study, “Healthcare and economic burden of ANCA-associated vasculitis in Italy: an integrated analysis from clinical and administrative databases,” was published…

Muscle Biopsies Could Be Useful in AAV Diagnosis, Study Asserts

Muscle biopsies could be used to diagnose ANCA-associated vasculitis (AAV), a new study indicates. The finding suggests that such biopsies are most informative in females or in people with certain inflammation-related conditions. The study, “Muscle biopsy in anti-neutrophil cytoplasmic antibody–associated vasculitis: diagnostic yield depends on anti-neutrophil…

Extracellular Vesicles of Neutrophils May Be Blood Biomarkers for AAV

Extracellular vesicles, or the tiny membrane-bound particles that are released from cells, could be used as a blood biomarker of disease activity in people with ANCA-associated vasculitis (AAV), a new study suggests. The study, “Microparticles expressing myeloperoxidase as potential biomarkers in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides…

Fingolimod May Have Potential as AAV Treatment, Rat Study Indicates

Fingolimod (FTY720), a medication used to treat multiple sclerosis, also appears to ease many of the symptoms of ANCA-associated vasculitis (AAV), a new study in rats suggests. The study, “Sphingosine-1-phosphate receptor modulator FTY720 attenuates experimental myeloperoxidase-ANCA vasculitis in a T cell-dependent manner,” was published…
