Abstract
Henoch–Schönlein purpura is a systemic vasculitis that is characterized by the deposition of IgA-containing immune complexes. The disease generally occurs in children, with 2:1 male to female predominance, and is usually preceded by a upper respiratory infection.
The gastrointestinal (GI) symptoms seen are:
Abdominal pain (80 % of patients): colicky, periumbilical, can be associated with vomiting and distension and may be severe enough to resemble a surgical abdomen
GI bleeding: occult or symptomatic; occurs in 50 % of patients, usually self-limited
Intussusception: usually ileoileal
The clinical signs and findings include:
Patients most often present with rash, GI symptoms, arthritis, and nephropathy
