A patient in New York was diagnosed with ANCA-associated vasculitis and compromised kidney function caused by levamisole-adulterated cocaine, which scientists consider to be a rare occurrence. The study, “Unusual case of levamisole-induced dual-positive ANCA vasculitis and crescentic glomerulonephritis,” was published in BMJ Case Reports. Levamisole is…

An individually tailored treatment with Rituxan (rituximab) is as effective as the standard fixed-schedule regimen in preventing relapses over 28 months in ANCA-associated vasculitis (AAV) patients in remission.
