Bactericidal permeability increasing protein-anti-neutrophil cytoplasmic antibody- associated vasculitis complicated with bronchiectasis: a case report and literature review / 中华肾脏病杂志

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a group of systemic small vasculitis characterized by the detection of ANCA in serum. Bactericidal permeability enhancing protein (BPI) is one of the target antigens of ANCA. BPI-ANCA-associated vasculitis is not common clinically, and the combination of bronchiectasis is not accidental. The paper reported a case of BPI-ANCA-associated vasculitis with renal damage combined with bronchiectasis. We reviewed relevant literature to explore the characteristics of BPI-ANCA-associated vasculitis and the correlation between bronchiectasis and ANCA-associated vasculitis, so as to improve the clinician's understanding on this disease.
