People with ANCA-associated vasculitis (AAV) patients whoo have low blood levels of sulfatides, a type of fatty molecule, are significantly more likely to have future kidney failure, a single-center study in South Korea indicates. The predictive potential of blood sulfatide levels was independent of direct associations with kidney involvement…

While it’s rare in children, ANCA-associated vasculitis (AAV)-related glomerulonephritis, that is, an inflammation of the glomeruli, the kidneys’ filtering units, is associated with high rates of kidney failure or death, a study shows. Also, scar tissue accumulating in the glomeruli, other kidney tissue abnormalities, and high protein levels in…

Lower blood counts of platelets — tiny cell fragments involved in blood clotting — at the time that ANCA-associated vasculitis (AAV) is diagnosed may be a marker of poorer kidney function and a higher risk of kidney failure, according to a retrospective study from China. Findings suggest that “platelet…

The risk of poor outcomes after a kidney transplant is considerably higher for ANCA-associated vasculitis (AAV) patients with kidney failure than people without the autoimmune disease, ranging from infections and disease relapse to death, a review study reports. But long-term survival rates for those who make it through the…

High blood creatinine levels and results from kidney biopsies at the time of diagnosis were the best predictors of kidney failure risk in people with ANCA-associated vasculitis (AAV) with severe kidney disease, a study found. Blood creatinine levels, a marker of kidney damage, and kidney biopsy findings also predicted…

Tavneos (avacopan) improved kidney function and reduced the need for the glucocorticoid prednisone in four older patients who had signs of kidney failure due to ANCA-associated vasculitis (AAV), researchers in Canada report. While Tavneos may help patients enter into remission without the harmful side effects of glucocorticoids, “more…

ANCA-associated vasculitis (AAV) with kidney involvement is the most common cause of kidney disease among elderly people, but most older patients appear to benefit from appropriate therapy as well as younger AAV patients with kidney damage. That’s according to a study in Germany that found no significant differences in…

People with ANCA-associated vasculitis (AAV) that affects their kidneys are at a significantly increased risk of kidney failure if they show a high proportion of inflamed glomeruli (the organ’s filtering units) on biopsies collected at diagnosis, a study has found. The study, “Renal histopathological predictors of…

The ANCA Renal Risk Score, known as the ARRS, was found to be better than standard methods at predicting the likelihood of kidney failure in children with ANCA-associated vasculitis (AAV) who have kidney inflammation, a study in China showed. “Our findings suggest that ARRS is an independent risk factor…

The ANCA Renal Risk Score (ARRS) — based on kidney biopsy and lab results — could accurately predict kidney failure in a large group of Scottish people with ANCA-associated vasculitis (AAV), a study shows. The test better discriminates the risk of kidney failure in AAV and may offer clinicians…
