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…

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…

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 …

Rare diseases affect about 30 million Americans — roughly the same number as those with type 2 diabetes. Yet only 5 percent of the estimated 7,000 rare diseases known to science have cures or treatments approved by the U.S. Food and Drug Administration (FDA). Raising awareness of those illnesses and highlighting…

Tumors caused by granulomatosis with polyangiitis (GPA)-related lesions appear to be especially sensitive to radiation and can be treated effectively with low-dose radiotherapy, a case report suggests. The study, “Radiotherapy in advanced glottic laryngeal carcinoma in a patient with Wegener’s granulomatosis: how much radiation dose is needed?,”…

Real-world use of MabThera (rituximab) as an induction treatment for patients with ANCA-associated vasculitis (AAV) on low-dose prednisone led to successful complete remission rates that matched those seen in a key clinical trial, according to a study. However, the investigators believe that the increasing number of relapses after treatment…

In rare cases, eosinophilic granulomatosis with polyangiitis (EGPA) may serve as a trigger for thrombotic microangiopathy (TMA), a disease that affects the smallest blood vessels in the body and often involves blood clots, a case report suggests. It remains unclear why these two rare disorders may be interconnected. However, a common underlying…

The world’s biggest gathering of rare disease researchers, patient groups, pharmaceutical executives, and government officials is planned for April 10–12 in a Washington, D.C., suburb. Some 1,200 people have already registered to attend the World Orphan Drug Congress (WODC) USA 2019, set to take place at the Gaylord National Harbor…

Adding intravenous methylprednisolone pulses to standard treatment for inducing remission in severe cases of ANCA-associated vasculitis does not confer clinical benefits and increases the risk of infection and diabetes, a study suggests. The study, “Intravenous pulse methylprednisolone for induction of remission in severe ANCA associated Vasculitis: a multi-center retrospective…

ANCA-associated vasculitis (AAV) diagnoses increased and overall and renal survival improved over a period of 23 years, a real-world study in the U.K regions of Lancashire and South Cumbria reports. These improved outcomes may be due to earlier diagnosis and better management of AAV and chronic kidney disease in recent…
