The Intricate Interplay of Gastrin in Mary’s Hormonal Imbalance

January 10, 2024by Mian Marssad0

Case Study:

Patient: Mary, a 42-year-old woman with a history of chronic heartburn and intermittent episodes of severe abdominal pain.

Presenting Symptoms:

  • Heartburn and acid reflux for over 10 years, worsening recently despite medication.
  • Recurrent episodes of severe abdominal pain lasting for hours, often accompanied by nausea and vomiting.
  • Unexplained weight loss over the past year.
  • Fatigue and difficulty sleeping.

Medical History:

  • No prior surgeries or major illnesses.
  • Family history of diabetes and obesity.
  • Takes over-the-counter antacids for heartburn relief.

Initial Investigations:

  • Upper endoscopy reveals multiple gastric ulcers and inflammation in the duodenum.
  • Biopsy confirms the presence of gastritis (inflammation of the stomach lining).
  • Blood tests show elevated gastrin levels and abnormal insulin sensitivity.
  • Bone density scan indicates early signs of osteoporosis.

Differential Diagnosis:

  • Zollinger-Ellison syndrome (ZES)
  • Gastroesophageal reflux disease (GERD) with complications
  • Peptic ulcer disease with complications
  • Early-stage type 2 diabetes
  • Gastric neuroendocrine tumor

Further Investigations:

  • Gastrin stimulation test to confirm or rule out ZES.
  • Imaging tests (CT or MRI) to rule out pancreatic tumors associated with ZES.
  • Comprehensive metabolic panel to assess diabetes markers and insulin resistance.
  • Bone mineral density analysis for further evaluation of osteoporosis.

Diagnosis:

Based on the combined clinical picture, elevated gastrin levels, and positive gastrin stimulation test, Mary is diagnosed with ZES. Further investigations do not reveal evidence of a pancreatic neuroendocrine tumor, indicating primary ZES arising from the stomach or duodenum.

Treatment Plan:

  • Proton pump inhibitor (PPI) medication to suppress gastric acid secretion and promote ulcer healing.
  • Surgical consultation to evaluate options for gastrin-producing tumor removal if localized in the stomach or duodenum.
  • Nutritional counseling to manage weight and optimize blood sugar control.
  • Calcium and vitamin D supplementation to address early signs of osteoporosis.
  • Ongoing monitoring of gastrin levels, ulcer healing, and metabolic parameters.

Potential Impact of Gastrin’s Duality:

  • In Mary’s case, gastrin acts as a “foe,” driving excessive acid production and contributing to ZES-related complications like ulcers and abdominal pain.
  • However, her elevated gastrin levels might also have a protective effect, stimulating bone cell growth and potentially contributing to her early-stage osteoporosis.
  • Understanding the complex interplay of gastrin in her specific case helps tailor treatment strategies that address both the immediate complications and potential long-term health concerns.
