Some blood vessel inflammation cases stem from a group of diseases collectively known as ANCA-associated vasculitis, while others don’t. Chinese scientists have discovered a first: a non-ANCA-associated vasculitis case that turned into an ANCA-associated one. Doctors call an ANCA-associated case an ANCA-positive case, and a non-associated case an ANCA-negative case. At…

Researchers developed a new questionnaire that assesses a patient’s perspective on how anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, or AAV, impacts health-related quality of life. While the questionnaire should be shorter and validity testing is needed, this patient-reported measure has already helped clinicians understand which health-related outcomes matter most to…

Persistent findings of blood in the urine may predict the likelihood of kidney disease returning in patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, a study reports. And it underscores the role that a simple test — urinalysis — can play in predicting a patient’s risk. “The findings of this study…

A rare case of inflammatory disease affecting the protective membrane of the central nervous system was linked to anti-myeloperoxidase (MPO) autoantibodies in a case report. The Japanese study, “A case of suspected MPO-ANCA-related hypertrophic pachymeningitis with atypical presentation,” was published in the Journal of Family and…

Prolonged exposure to the silica dust that construction and other industries generate contributes to the development of the small blood vessel disease known as microscopic polyangiitis, according to a Japanese case study. Microscopic polyangiitis, or MPA, is one of three types of a category of diseases known as ANCA-associated vasculitis, or…
