# Statin therapy for persistent endogenous Cushing syndrome

## STEP 1 — Gather Information
Obtain lipid panel (LDL-C, HDL-C, triglycerides), confirm persistent endogenous Cushing syndrome via biochemical testing after definitive therapy, assess life expectancy and comorbidities, and review current medications (especially mitotane).

## STEP 2 — Rule In / Rule Out
Is the patient an adult with biochemically confirmed persistent endogenous Cushing syndrome? If yes, proceed to STEP 3; if no, consider alternative diagnoses or cured Cushing syndrome and follow general population lipid management.

## STEP 3 — Classify or Stratify
Measure LDL-C: if LDL-C >70 mg/dL (1.8 mmol/L), classify as candidate for statin initiation; if LDL-C ≤70 mg/dL, still consider statin based on overall cardiovascular risk but plan reassessment in 3–6 months.

## STEP 4 — Decide
Initiate moderate-intensity statin (e.g., atorvastatin 10–20 mg daily or rosuvastatin 5–10 mg daily) as adjunct to lifestyle modification (dietary changes, increased physical activity); obtain baseline liver enzymes and creatine kinase; schedule follow‑up lipid panel and safety labs in 3–6 months.

## Clinical Guardrails / Mimics / Pitfalls
Do not initiate statin therapy in pregnancy or in patients attempting pregnancy; avoid simvastatin and lovastatin when patients are on mitotane due to increased risk of myotoxicity—prefer fluvastatin, pravastatin, or rosuvastatin; statin therapy may be inappropriate in patients with limited life expectancy (e.g., untreated malignancy); monitor for statin‑associated muscle symptoms and hepatic enzyme elevations.

## Concrete Clinical Example
A 48‑year‑old woman with persistent Cushing syndrome after transsphenoidal adenomectomy has LDL‑C 138 mg/dL, HDL‑C 42 mg/dL, triglycerides 160 mg/dL, and is not pregnant. She is started on atorvastatin 20 mg daily plus Mediterranean diet and brisk walking 30 minutes daily; lipids are rechecked at 4 months showing LDL‑C 78 mg/dL with no adverse effects.
