Osteoporosis Treatment Denosumab May Cause ANCA Vasculitis, Case Report Suggests

Denosumab, an approved treatment for osteoporosis, may sometimes trigger antineutrophil cytoplasmic antibody (ANCA) associated vasculitis with cytoplasmic ANCAs, a case study reports. While this treatment has been linked with vasculitis, this is the first report of a denosumab-derived cytoplasmic-ANCA vasculitis, the researchers say. The case study, “c-ANCA vasculitis…

Small Particles Produced by Platelets May Worsen Inflammation in AAV, Study Contends

Platelet-derived microparticles (PMPs) — small particles produced and released by platelets in the blood — may worsen inflammation in patients with ANCA-associated vasculitis, according to a recent study. The findings of the study, “Platelets release proinflammatory microparticles in anti-neutrophil cytoplasmic antibody-associated vasculitis,” were published in Rheumatology.

Dividing AAV According to Antibodies Provides No Further Benefit for Prognosis, Study Reports

Dividing ANCA-associated vasculitis (AAV) into subgroups defined by type of antibodies does not provide additional value for clinical prognosis, according to recent research. The study, “Clinical impact of subgrouping ANCA-associated vasculitis according to antibody specificity beyond the clinicopathological classification,” appeared in the journal Rheumatology. Different…

Rise in MPO-ANCA Antibodies After Remission May Predict Relapse

Among ANCA-associated vasculitis patients in remission — particularly those with manifestations in their kidneys — the reappearance of MPO-ANCA antibodies may be a sign of disease relapse, a study suggests. The study, “Association Between Reappearance of Myeloperoxidase-Antineutrophil Cytoplasmic Antibody and Relapse in Antineutrophil Cytoplasmic Antibody-Associated Vasculitis,” was…

Antibody Fragment May Be Used to Treat ANCA Vasculitis, Study Reports

A piece of an antibody targeting a protein involved in cholesterol transport and metabolism might be an effective treatment for anti-neutrophil cytoplasmic autoantibodies (ANCA) vasculitis, a study suggests. The study, “Efficacy of a recombinant single-chain fragment variable region, VasSF, as a new drug for vasculitis,” was published in …
