Abstract
OBJECTIVE: Immunoglobulin A vasculitis (IgAV) is a systemic small vessel vasculitis common in children. Pancreatic involvement in IgAV is rare. The purpose of this study was to analyze the clinical characteristics of IgAV-related acute pancreatitis in children. METHODS: Records of patients with IgAV-related acute pancreatitis admitted to our institution between January 2016 and December 2019 were reviewed. We summarized the clinical characteristics, laboratory characteristics, imaging findings, treatment, and outcomes of 15 children with IgAV-related acute pancreatitis. RESULTS: The patients' median age was 9.6 years. Pancreatitis was the initial manifestation of IgAV in 3 patients. All patients had abdominal manifestations, including abdominal pain (15/15), vomiting (10/15), and gastrointestinal bleeding (7/15). Serum amylase and lipase levels were elevated in all patients. Serum amylase in 4 cases reached more than three-fold elevation and serum lipase in 14 cases reached more than three-fold elevation. Morphological abnormalities and abnormal signals of the pancreas were observed in 13 cases by magnetic resonance imaging. Pancreaticobiliary maljunction was seen in 3 cases by magnetic resonance cholangiopancreatography. Glucocorticoid therapy and intravenous immunoglobulins were used to treat acute pancreatitis in IgAV. All patients showed clinical improvement after treatment. During the follow-up period of 6-12 months, all 15 cases with pancreatitis were cured without recurrence. CONCLUSIONS: Pancreatic involvement is rare in IgAV; however, this should be considered in IgAV patients with severe abdominal pain. The timely application of steroid therapy is important for IgAV-associated pancreatitis. Key Points • Acute pancreatitis is a rare complication of immunoglobulin A vasculitis (IgAV). • Acute pancreatitis can be the initial manifestation of IgAV. It is important to evaluate for pancreatitis while IgAV patients with severe abdominal pain. • A common image finding of IgAV-associated pancreatitis was swelling of the pancreas. • Glucocorticoid therapy and intravenous immunoglobulins is helpful in alleviating acute pancreatitis in IgAV.
