Triad: non-thrombocytopenic palpable purpura, abdominal pain, arthritis
Most common vasculitis in childhood (ages 2-11 yr)
commonly white/asian males
5% of cases associated with intussusception (abdominal vasculitis)
Most cases preceded by a URI
95% recover completely after 3-4wk
Progression to renal insufficiency in 5-15% of children
Presentation in adults is 30-50% risk
Adults may require more aggressive treatment with steroids +/- cyclophosphamide
Lab Abnormalities
Coag studies normal
CRP/ESR elevated
CBC- increased white count and platelet count
UA- hematuria and proteinuria
Guaiac positive stool
Abd US can show intussusception
Biopsy is definitive NOT labs

ESR- 43mm/hr (ref range 0-20-mm/hr)
CRP- 9.9 mg/dL (ref range <=1.0mg/dL)
WBC- 13.8K/mcL (ref range 4.2-11.0K/mcL)
Hgb- 13.9g/dL (ref range 12.0-15.5g/dL)

Procalcitonin- 0.15ng/mL (ref range <=0.09ng/mL)
Management
Supportive
NSAIDs may worsen renal or GI disease
Prednisone 1mg/kg/day
Severe arthralgias, abdominal disease, or scrotal disease
IVIG to prevent or treat glomerulonephritis
Admission Criteria:
Renal failure
Significant GI Bleed
Intussusception
Outpatient management appropriate for most cases with rheumatology and renal
Recurrence rate 33%
Our patient was started on 1mg/kg of Prednisone in the emergency department and admitted for further workup where she obtained EGD, colonoscopy and skin biopsy. She also received blood cultures, hepatitis, HIV, and antibody testing. The patient responded well to steroid therapy and was discharged home several days later. Her rash continued to improve and resolved within two weeks and her kidney function remained normal.
