Henoch-Schönlein Purpura (Childhood Immunoglobulin A Vasculitis) caused by dental infection in one of fraternal twins: A case report

ABSTRACT

@#Henoch-Schönlein purpura (HSP) is the most common form of vasculitis in children that is clinically characterized by the classic triad of palpable purpura, joint symptoms, and abdominal pain. A 6-year-old girl, one of fraternal twins, was admitted to the Pediatric Department, Universitas Airlangga with fever, rashes on legs and arms and intermittent mild abdominal pain. She had multiple purpuric rashes on her extremities, abdomen and buttocks. Laboratory investigation revealed immunoglobulin A level of 289.6 mg/dL. The patient was diagnosed as HSP vasculitis according to EULAR criteria and treated with intravenous methylprednisolone. She was discharged after three days with normal physical examination and laboratory findings. Intraoral examination showed dental infection in the upper tooth region. The paediatrician suspected a correlation between HSP and her dental infection. The dental infection and genetic susceptibility may be the stimulant factors for the autoimmune reactions that caused HSP vasculitis. Hence, it might be useful to investigate the presence of dental infection in the etiology of HSP cases.
