Abstract

Hereditary spherocytosis (HS) is a genetic disorder characterized by the production and destruction of spherocytes due to a deficiency of red cell membrane cytoskeletal proteins, resulting in the clinical presentation of chronic hemolytic anemia. This disease can be accompanied by an aplastic crisis due to parvovirus B19 infection. Parvovirus B19 infection causes diseases such as erythema infectiosum and arthritis, and can also trigger various autoimmune diseases, including autoimmune hemolytic anemia (AIHA). Here, we report a rare case of AIHA developing 3 months after an aplastic crisis due to parvovirus B19 infection in an 11-year-old boy with HS and provide the relevant literature review.
