Antineutrophil Cytoplasmic Antibody (ANCA)-Associated Glomerulonephritis in a 15-year-old Patient After Receiving the Second Dose of the BBIBP-CorV (Sinopharm) COVID-19 Vaccine: A Case Report

Introduction: Antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV) is a group of multisystemic autoimmune diseases that can involve organs such as kidneys and respiratory tracts. Since the initiation of COVID-19 vaccines, there have been few cases of antineutrophil cytoplasmic antibody (ANCA) glomerulonephritis development after receiving vaccine doses. Case Presentation: This report describes a 15-year-old man who has developed ANCA-associated glomerulonephritis (AAGN) after receiving the second dose of BBIBP-CorV (Sinopharm) COVID-19 vaccine. Conclusions: Development of AAGN after both natural SARS-CoV-2 infection and following other vaccinations raises the question of the possible causality between the two. Considering the widespread use of COVID-19 vaccines, it is highly important to investigate their possible side effects.
