Return to Normal Life After AIDS as a Reason for Lost to Follow-up in a Community-Based Antiretroviral Treatment Program

This case report highlights a very rare adverse drug reaction caused by oral pantoprazole resulting in acute pancreatitis. An 11-year-old boy was diagnosed with gastroesophageal reflux disease. Apart from general advice for lifestyle and dietary changes, he was symptomatically prescribed oral pantoprazole 40 mg once daily 30 minutes before meals for 4 weeks. The symptoms of gastroesophageal reflux disease were improving gradually, but the patient developed progressive symptoms of acute pancreatitis and was admitted in the emergency department with acute abdominal pain. Relevant investigations were done, and it was diagnosed as a case of acute pancreatitis. There was no evidence of any other possible hereditary, traumatic, surgical, metabolic, infective, organic, or pathologic causes giving rise to this condition, and this acute pancreatitis was probably drug (pantoprazole) induced. Dechallenge was done, and the patient was treated conservatively resulting in reversal of the diseased state. Naranjo adverse drug reaction probability scale suggested that the likelihood that oral administration of pantoprazole was responsible for the acute pancreatitis was 'probable.'
