title: Valproic acid-induced acute pancreatitis in pediatric age: case series and review of literature.
abstract: Valproic acid (VPA) is commonly prescribed medication for epilepsy, migraine and bipolar disorder. Although the common adverse effect associated with VPA are typically benign, less common adverse effect can occur; these include hepatotixicity, teratogenicity and acute pancreatitis (AP). VPA-induced pancreatitis does not depend on valproic acid serum level and may occur anytime after onset of therapy. Re-challenge with VPA is dangerous and should be avoided. The diagnosis of VPA-induced pancreatitis seems to be underestimated because of difficulties in determining the causative agent and the need for a retrospective re-evaluation of the causative factor. More of idiopathic pancreatitis should be a drug-induced pancreatitis. We report four cases of VPA-induced AP found in a group of 52 cases of AP in children come to our attention from January 2008 to December 2012. The aim of these reports is to point out our experience about clinical presentation, diagnosis, management, outcome in children with VPA-induced AP and review of literature.
