Zollinger-Ellison Syndrome

When dealing with Zollinger-Ellison syndrome, a rare condition marked by excessive gastric acid due to gastrin‑producing tumors. Also known as ZE syndrome, it can cause severe peptic ulcers and diarrhea.

One of the main culprits is the gastrinoma, a neuroendocrine tumor that secretes high levels of gastrin. This hormone fuels gastric acid hypersecretion, which in turn erodes the lining of the stomach and duodenum. The cascade often leads to recurrent, treatment‑resistant peptic ulcers. Because the tumors are usually located in the pancreas or duodenum, imaging studies like endoscopic ultrasound become essential for accurate detection.

Key Aspects of Zollinger-Ellison Syndrome

Many patients with ZE syndrome also carry a genetic backdrop called MEN1 syndrome, an inherited disorder that predisposes to multiple endocrine tumors. MEN1 explains why a subset of individuals develop not only gastrinomas but also parathyroid and pituitary adenomas. Recognizing this link helps clinicians screen for related conditions early, preventing complications down the line.

Managing the acid surge is the cornerstone of therapy. Proton pump inhibitors (PPIs) such as omeprazole or esomeprazole are the most effective drugs to suppress gastric acid production. They bind irreversibly to the H⁺/K⁺‑ATPase pump in parietal cells, providing long‑lasting control of symptoms. High‑dose PPI regimens are often required, and dose adjustments are guided by acid output measurements.

Beyond medication, surgical removal of the gastrinoma offers a potential cure, especially when the tumor is localized and no metastasis is present. However, surgery carries risks, and many patients rely on lifelong PPI therapy. For metastatic disease, targeted therapies like somatostatin analogs can reduce gastrin secretion, while chemotherapy may shrink tumor burden.

Nutrition also plays a role. Patients are advised to avoid foods that stimulate acid, such as caffeine, alcohol, and very spicy dishes. Small, frequent meals can help minimize symptoms, and a dietitian’s input ensures adequate nutrition despite possible malabsorption.

Follow‑up care is a continuous process. Regular endoscopic examinations check ulcer healing, while periodic imaging monitors tumor progression. Blood tests measuring fasting gastrin levels help assess treatment response and detect recurrence early.
