Abstract:
Henoch-Schoenlein purpura, also known as anaphylactoid purpura, is characterized by palpable purpura, colicky abdominal pain, gastrointestinal hemorrhage, arthralgias, and renal involvement. Histopathologically, the condition represents a vasculitis, and in fact, it may be the most common vasculitis syndrome affecting children. The pathogenesis of Henoch-Schoenlein purpura remains poorly understood, but it is postulated that an unknown antigenic stimulus causes elevation of circulating IgA and that complement activation leads to necrotizing vasculitis. All of its clinical features are attributable to wide spread vasculits. Abdominal pain is the most common gastrointestinal symptom, but intestinal bleeding and intussusception may occur. Mesenteric vasculitis is a rare but potentially serious complication of systemic vasculitis. It is reported in association with rheumatoid arthritis, systemic lupus erythematosus, scleroderma, polyarteritis nodosa, and giant cell arteritis in adult patients. Typical features are diffuse non-specific abdominal pain progressing on occasion to gastrointestinal hemorrhage, perforation, or more rarely infarction. Fortunately intestinal infarction is a rare complications, but if present carries a high chance of mortality, and swift management of the underlying vasculitis is crucial. We describe here an unusual case of a small intestinal infarction associated with Henoch-Schoenlein purpura caused by mesenteric vasculitis.
