The clinical picture consistent with HSP, with pancretitis & GI involvement. Soyer et al. Acute pancreatitis: a rare presenting feature of Henoch Schonlein purpura. J Paediatr Child Health. 2008 ; 44(3):152-15 3 yr old female child presented with acute pancreatitis had characteristic HSP rash after 2 day of hospitilisation. Although pancreatitis occurs after the onset of rash, it may also occurs as presenting feature.

The most common vasculitis of childhood which involves Skin, GI tract, Joints & kidney. IgA containing immune complex deposit in association with inflammatory reaction of the vessels. Epidemiology 14-20/1,00,000 children per year M:F -1.2-1.8: 1 Children > adults Peak age group- 3-10 yrs Common in winter months Ref: Nelson textbook of paediatics & Brenner & Rector s,the kidney
Skin - 100% Palpable purpura lasting for 3-10 days Symmetrical, gravity dependent areas. Joints 75% Arthritis or arthralgia, self limited & oligoarticular No erosion or deformity GI - 80% Abd pain, vomiting, diarrhea, paralytic ileus, malena, intussusception rarely perforation. Renal - 50% Hematuria, proteinuria, hypertension, frank nephritis, nephrotic syndrome.
The typical glomerular pathology is mesangial & endocapillary proliferative GN with variable crescent formation. In severe cases there will be inflammatory infiltrates & necrotising features. Immunoelectron microscopy predominance of IgA with some C3 & IgG in the deposits.
Clinical diagnosis Mild leucocytosis, normal platelet. Serum IgA are often elevated but are not routinely measured. USG- abd for bowel wall edema and intussuception. Biopsy of skin & renal tissue- IgA deposition.
GI involvement Perforation Renal disease - long term complication. Serial monitoring of blood pressure and urinalyses for 6 mo after diagnosis, those who presented with hypertension or urinary abnormalities.
Supportive Role of steroids-controversial in HSP nephritis Empiric use of prednisone reduces abdominal and joint pain.
Childhood HSP- excellent prognosis. Recurrences 30% of children within 4-6 months of diagnosis. Chronic renal disease develops in 1-2% of children with HSP, 8% of those with HSP nephritis go on to have ESRD.
Abdominal pain in HSP is explained by bowel wall edema and vasculitis but it may also be due to acute pancreatitis. Even if rare, atypical presentation of HSP initially with acute pancreatitis should be remembered in order to plan the specific treatment and avoid unnecessary surgical interventions.
Thank you
Obstruction of papilla of vater, invasion of CBD or pancreatic duct. Children rare, smaller hepatobiliary network. Prognosis excellent.
