Progranulin Protein Levels in Blood May Predict AAV Severity

Blood levels of progranulin — a protein involved in cell development, cell growth, and wound healing — may predict the severity of ANCA-associated vasculitis (AAV), a new observational study suggests. According to researchers, serum progranulin, or the protein’s levels in the bloodstream, “could be used as a predictive marker…

Researchers Call for New System to Better Classify Vasculitis

A new classification system, based on the underlying cause of disease, may be necessary to better understand ANCA-associated vasculitis (AAV) and other disorders characterized by inflammation in the blood vessels. That’s according to a team led by scientists at Aarhus University, in Denmark, who published their idea for the…

Repeat Kidney Biopsies May Help Better Determine Active Disease

After an initial biopsy shows signs of active ANCA-associated vasculitis (AAV) affecting the kidneys, repeat biopsies are better at determining active disease than standard measures of kidney function, a new observational study reports. Such repeat kidney biopsies may help determine treatment response and personalize care plans for people with…

Kidney Specialists May Benefit Some EGPA Patients, Report Suggests

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.

Thyroid Med for Graves’ Disease Triggered AAV

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…
