Environmental factors influencing the risk of ANCA-associated vasculitis
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of diseases characterized by inflammation and destruction of small and medium-sized blood vessels. Clinical disease phenotypes include microscopic polyangiitis (MPA), granulomatosis ...
Multiple case reports have shown that sustained exposure to silica in an occupational environment resulted in a significantly increased risk of ANCA positivity. A meta-analysis involving six case-control studies showed that silica exposure was positively associated with AAV incidence.
Studies have confirmed the dose-related effects of silica exposure. A meta-analysis showed that silica exposure was positively associated with AAV.
