What Is Zollinger-Ellison syndrome (ZES)?

Under Thyroid, Adrenal & Endocrine Disorders diagnostic criteria (E16.4), workup for Zollinger-Ellison syndrome (ZES) (also termed Zollinger-Ellison syndrome or Disorder) integrates morning pituitary-target hormone in Zollinger-Ellison syndrome (ZES) (E16.4: axis assays) with evidence-graded therapy tailored to Morning Serum Cortisol in Zollinger-Ellison syndrome (ZES) (E16.4: (8 AM)) response.

Pathophysiology, Underlying Causes & Clinical Presentation

Zollinger-Ellison syndrome (ZES) (E16.4) alters thyroid & endocrine homeostasis through autoimmune glandular inflammation [Zollinger-Ellison syndrome (ZES) E16.4]; clinical remission targets TPO & Thyroglobulin in Zollinger-Ellison syndrome (ZES) (E16.4: Antibodies) within Negative / < 9 IU/mL (E16.4).

Common Symptoms & Clinical Signs

  • • Presentation of Zollinger-Ellison syndrome (ZES) (E16.4): dry skin, brittle in Zollinger-Ellison syndrome (ZES) (E16.4: nails, diffuse hair)
  • • Secondary Zollinger-Ellison syndrome (ZES) clinical sign: irregular bowel motility [Zollinger-Ellison syndrome (ZES) E16.4]
  • • Symptom flares in Zollinger-Ellison syndrome (ZES) correlating with Morning Serum Cortisol in Zollinger-Ellison syndrome (ZES) (E16.4: (8 AM)) deviation outside 10 – 18 mcg/dL (E16.4)
  • • Functional thyroid & endocrine impact requiring morning pituitary-target hormone in Zollinger-Ellison syndrome (ZES) (E16.4: axis assays) evaluation (E16.4)
