Blood vessels in the kidneys that swell due to an infection can mimic ANCA-associated vasculitis (AAV), making diagnosis and treatment of these two conditions challenging, a case study shows.  Identifying and treating infections associated with AAV are essential to helping patients, the researchers…

The bacterium that causes Q fever — an infection usually transmitted to humans by barnyard animals — can trigger anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV), a recent case report suggests. Titled “Coxiella burnetii endocarditis as a possible cause of ANCA-associated vasculitis,” the report was published…

The U.S. Food and Drug Administration (FDA), a vast government bureaucracy, employs about 17,500 people and had a budget of $5.7 billion in 2019. Yet even with its enormous resources, the FDA these days relies more and more on patients to…

People in Poland with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are treated according to existing guidelines, and the most common treatment-associated adverse event is infection, according to a nationwide study. The study, “Treatment and its side effects in ANCA-associated vasculitides – Study based on POLVAS registry…

An elderly woman was diagnosed with the granulomatosis with polyangiiti (GPA) subtype of ANCA-associated vasculitis (AAV) after being misdiagnosed with pneumonia, illustrating the challenges in diagnosing this condition, according to a case report.  All types of AAV should be in the differential diagnosis for all…

Muscle weakness may be an under-recognized symptom of antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) with diagnosis likely requiring a biopsy of the muscle itself, a case report has found. The report, titled “Severe proximal muscle weakness with normal CK as a presenting feature of ANCA-associated vasculitis,”…
