| name | enda-monitor-glucocorticoid-replacement |
| description | Monitors glucocorticoid replacement in primary adrenal insufficiency (PAI) patients using clinical assessment of body weight, postural blood pressure, energy levels, and signs of frank glucocorticoid excess. Trigger phrases include "PAI patient on glucocorticoid replacement," "assess for weight gain or insomnia," and "evaluate for postural hypotension or fatigue." |
Monitor Glucocorticoid Replacement via Clinical Assessment
STEP 1 — Gather Information
Measure body weight, sitting and standing blood pressure (postural change), query energy levels (fatigue, lethargy, insomnia), and inspect for signs of glucocorticoid excess (weight gain, central obesity, peripheral edema, hyperglycemia, skin thinning) or insufficiency (hyperpigmentation, salt craving, weight loss, postural hypotension).
STEP 2 — Rule In / Rule Out
Determine if any signs of glucocorticoid excess are present; if yes, proceed to assess for over-replacement, if no, proceed to assess for under-replacement.
STEP 3 — Classify or Stratify
Classify the patient as glucocorticoid excess (≥2 excess signs), adequate (no excess or insufficiency signs), or insufficiency (≥2 insufficiency signs such as fatigue, weight loss, postural hypotension, hyperpigmentation).
STEP 4 — Decide
If excess: consider glucocorticoid dose reduction by 10‑20%; if insufficiency: consider dose increase by 10‑20%; if adequate: maintain current dose and schedule routine reassessment in 3‑6 months.
Clinical Guardrails / Mimics / Pitfalls
Do not rely solely on serum cortisol or ACTH for dose adjustments; avoid using dexamethasone for replacement due to Cushingoid risk; do not make dose changes based on a single vital sign; consider concomitant medications that alter cortisol metabolism (e.g., phenytoin, rifampicin); remember that weight alone can be misleading in edema or sarcopenia.
Concrete Clinical Example
A 50‑year‑old man with PAI on hydrocortisone 25 mg daily reports 3 kg weight gain, insomnia, and mild ankle edema over 2 months; BP 128/78 mm Hg sitting, 122/76 mm Hg standing; energy low. Assessment shows excess signs (weight gain, insomnia, edema). Decision: reduce hydrocortisone to 20 mg daily, re‑evaluate in 4 weeks.
