Inflammatory Protein, PTX3, May Be Potential AAV Diagnostic Biomarker

Significantly high levels of the inflammatory protein pentraxin-3 (PTX3) were found in the bloodstream and urine of people with ANCA-associated vasculitis (AAV), particularly those with kidney involvement, a study revealed. Unlike C-reactive protein (CRP), a widely used inflammatory biomarker, PTX3 correlated with standard measures of AAV disease activity before…

Cardiovascular Disease Risk Likely Increases After AAV Diagnosis

People with ANCA-associated vasculitis (AAV) have a higher risk of cardiovascular disease, especially in the months immediately following AAV diagnosis, a population-based analysis found. “Our study demonstrates a key ‘high-risk window’ that should prompt careful monitoring for CV [cardiovascular] disease and aggressive risk factor reduction,” the scientists said. The…
