Enterohemorrhagic Escherichia coli: trigger for small vessel vasculitis.

We describe the case of a 19-year-old woman who presented with abdominal pain, vomiting, and a palpable purpuric rash. The patient subsequently developed dysentery and was found to have an infection from Shiga toxin–producing Escherichia coli. The patient also met diagnostic criteria for IgA vasculi...

Sumario:	We describe the case of a 19-year-old woman who presented with abdominal pain, vomiting, and a palpable purpuric rash. The patient subsequently developed dysentery and was found to have an infection from Shiga toxin–producing Escherichia coli. The patient also met diagnostic criteria for IgA vasculitis (also known as Henoch Schönlein purpura) but had negative immunofluorescence biopsies of the rash. The patient was treated with steroids and achieved recovery. To our knowledge, this is the first documented case of IgA vasculitis in the setting of an enterohemorrhagic E. coli infection. This case highlights an atypical presentation of IgA vasculitis and the need to include small vessel vasculitis as a differential diagnosis when treating patients of all ages.
