People with granulomatosis with polyangiitis (GPA) may, in rare cases, develop dilated cardiomyopathy, a condition that causes the heart’s chambers to enlarge and become thinner, making it harder for it to pump blood effectively to the rest of the body, a recent case report shows. This case highlights the…

A biopsy of heart muscle may aid in the diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA) with cardiac involvement in patients negative for antineutrophil cytoplasmic antibodies (ANCAs) and with a negative skin biopsy, a case study suggests. The study, “Endomyocardial biopsy facilitates diagnosis of…

A recent case report highlights the difficulties that can occur in diagnosing granulomatosis with polyangiitis (GPA), a form of ANCA-associated vasculitis, after a patient was initially diagnosed and treated for tuberculosis. The male patient had a mass in the mediastinum — the space between the lungs — initially attributed…

Stellate ganglion block, a procedure where a pain-relieving medicine is injected into the neck to block certain nerves, might be a successful therapeutic approach for eosinophilic granulomatosis with polyangiitis (EGPA), a recent case study suggests. The procedure helped control symptoms and lower corticosteroid doses, which are associated with detrimental…

People with eosinophilic granulomatosis with polyangiitis (EGPA) who carry antibodies against the proteinase 3 (PR3) protein have more frequent relapses and a shorter time to relapse or death than patients without such antibodies, a South Korean study shows. These findings highlight the need to look for the presence of…

Plasma exchange and extracorporeal membrane oxygenation or ECMO — the use of an artificial lung — are two interventions that may benefit patients with severe ANCA-associated vasculitis (AAV) linked with pulmonary hemorrhage, a potentially life-threatening condition in which blood starts to build up in the lungs, a case…

Kidney disease is less common among people with eosinophilic granulomatosis with polyangiitis (EGPA), but some patients may experience severe kidney damage and require management by specialists, a case report shows. The study, “Renal Involvement in Eosinophilic Granulomatosis With Polyangiitis,” was published in the journal Kidney International Reports.

A woman of childbearing years developed ANCA-associated vasculitis (AAV) after taking the thyroid medication methimazole to treat her Graves’ disease, a case report shows. The patient experienced signs of respiratory and kidney failure secondary to AAV, but her symptoms improved after discontinuing the medication and starting immunosuppressive medications. Four…

Tavneos (avacopan), a recently approved add-on oral therapy for severe, active ANCA-associated vasculitis (AAV), will be distributed in the U.S. by PANTHERx, the country’s leading rare disease pharmacy. The announcement follows an agreement with ChemoCentryx, Tavneos’ developer, which selected the pharmacy as a limited distribution partner. “PANTHERx is proud…

The U.S. Food and Drug Administration (FDA) has approved Tavneos (avacopan) as an add-on therapy for people with severe active microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA), the two most common forms of ANCA-associated vasculitis. The approval comes after an advisory committee narrowly supported avacopan’s approval…
