Question 5 of 5
A 25-year-old man with a history of AIDS presents to the emergency room with severe abdominal pain and episodic nausea and vomiting. He describes the pain as constant; it is located in the epigastric area and radiates to the back. The pain started 12 hours ago and is becoming more intense. His current medications include dideoxyinosine (ddI), ganciclovir, and pentamidine. Physical examination reveals a low-grade fever and tenderness in the epigastric area without guarding or rebound. Blood tests demonstrate white blood cells of 6900/ L, amylase of 362 U/L, lipase of 428 U/L, and total bilirubin of 1.1 mg/dL. What is/are the possible cause(s) of this patient's problem?
Correct Answer: D
Rationale: This patient has acute pancreatitis as evidenced by his symptoms and elevated amylase and lipase. Cytomegalovirus is the most commonly reported viral infection that can involve the pancreas. HIV and many AIDS-related infections can affect the pancreas (e.g., cryptococcus, Mycobacterium tuberculosis, candida, and Toxoplasma gondii). Numerous medications may also cause acute pancreatitis (e.g., ddI, pentamidine, trimethoprim/sulfamethoxazole, and metronidazole).
