Sarah and the Hormonal Tug-of-War

January 7, 2024by Dr. S. F. Czar0

Case Study: 

The Patient: Sarah, a 42-year-old woman with a 5-year history of chronic pancreatitis, suffers from debilitating abdominal pain and recurrent bouts of pancreatitis.

The Clues:

  • Endoscopic examinations reveal pancreatic duct damage and scarring.
  • Gastric acid secretion tests show elevated levels.
  • Secretin stimulation tests show diminished bicarbonate response.

The Diagnosis: Sarah’s chronic pancreatitis seems driven by a disrupted secretin-gastrin balance.

The Tug-of-War:

  • Defective Secretin: Inflammation in Sarah’s duodenum has impaired S cell function, leading to insufficient bicarbonate production to protect her pancreatic ducts.
  • Gastrin Hyperactivity: Nerve damage triggered by previous pancreatitis episodes has stimulated G cells, causing excessive gastrin release and fueling inflammation.

The Treatment Plan:

  • Secretin Analogues: Sarah receives injections of a long-acting synthetic secretin to boost bicarbonate secretion and shield her ducts.
  • Gastrin Receptor Antagonist: She also takes medication to block gastrin’s action, reducing acid production and cell proliferation.

The Outcome:

After several months of combined therapy, Sarah’s pain episodes decrease significantly. Her pancreatic ductal inflammation shows signs of improvement, and her digestion improves. While the damage cannot be fully reversed, Sarah regains a better quality of life, thanks to restoring the hormonal balance.

Lessons Learned:

Sarah’s case highlights the importance of understanding the delicate hormonal interplay in chronic pancreatitis. By targeting both sides of the secretin-gastrin tug-of-war, we can offer individualized therapeutic strategies and hold hope for better management of this challenging disease.

Note: This case study provides a fictional but representative example of how the secretin-gastrin tug-of-war plays out in a patient with chronic pancreatitis. It showcases the diagnostic markers, potential treatment options, and potential outcomes while remaining concise and engaging.
