After 40 Years, NIH-Supported Researchers Identify Possible New Treatment for Severe Vasculitis

Investigators have made a major advance in treating people with a severe form of vasculitis, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, a rare but devastating disease of blood vessels. In a six-month study, a new treatment strategy provided the same benefits as the current standard of care used for more than 40 years but required less frequent treatments. Early results also suggest that patients with disease relapses — typically recurrences of fever, fatigue, kidney damage, or bleeding in the lungs — respond better to the new regimen.
