Abstract

Background: Perinuclear anti-neutrophil cytoplasmic antibodies (P-ANCA), a subset of ANCA, are associated with a multisystem vasculitis affecting small blood vessels in the body. A handful of adult patients who developed vasculitis post-COVID-19 infection have been reported. Although COVID-19 infection has been shown to drive an exaggerated immune response in the pediatric population, such as MIS-C (multisystem inflammatory syndrome in children), only one case of vasculitis following COVID-19 infection has been reported previously in children. Case presentation: Seventeen-year-old male with a past medical history of COVID-19 pneumonia two months prior presented with acute kidney injury/failure and diffuse alveolar hemorrhage (DAH). Rheumatologic workup revealed P-ANCA and Myeloperoxidase (MPO) positivity. Kidney biopsy showed necrotizing glomerulonephritis with limited immune complex deposition. Subsequently, he was treated with pulse steroids, plasmapheresis, and ultimately started on cyclophosphamide. Conclusions: To our knowledge, this report presents the second reported pediatric case of P-ANCA / MPO vasculitis following COVID-19 infection.
