Abstract

Severe acute respiratory syndrome coronavirus 2 infection in children with autoimmune neutropenia may be a cause for concern. In this retrospective study, none of the 24 autoimmune neutropenia cases manifested severe coronavirus disease 2019. We found a significant improvement in neutrophils and a reduction in lymphocytes at post-infection follow-up compared with the median of previous values. We speculate that this paradoxical effect may be due to postinfection immunological phenomena.
