A Case of Blood Vessel Inflammation Going from ANCA Antibody-negative to Positive

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…

Questionnaire Created to Assess Patient-reported Impact of AAV on Quality of Life

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…

Rare Inflammatory Disorder of Brain Meninges Linked to MPO-positive AAV

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…
