STEP 1 — Gather Information
Confirm adult growth hormone deficiency (GHD) diagnosis via low IGF-1 and/or subnormal GH stimulation test; document pituitary history or hypopituitarism if present.
Action: Proceed to lipid profile if GHD is confirmed.
STEP 2 — Rule In / Rule Out
Is the patient diagnosed with adult GHD?
- Yes: Continue to lipid assessment.
- No: Stop; lipid profile not indicated per this guideline.
Action: If yes, obtain fasting or non-fasting lipid panel.
STEP 3 — Classify or Stratify
Interpret lipid panel: total cholesterol, LDL-C, HDL-C, triglycerides.
- Normal: LDL-C <100 mg/dL, HDL-C ≥40 mg/dL (men) / ≥50 mg/dL (women), TG <150 mg/dL.
- Abnormal: Any value outside normal ranges.
Action: Classify as normal or dyslipidemia present.
STEP 4 — Decide
If dyslipidemia is identified, initiate cardiovascular risk assessment and consider lipid-lowering therapy per endocrine disorder guidelines; if normal, repeat lipid profile annually or as clinically indicated.
Action: Treat or monitor accordingly.
Clinical Guardrails / Mimics / Pitfalls
Do not use GH replacement solely to lower LDL-C to reduce cardiovascular risk; ensure lipid assessment is not delayed in hypopituitarism; non-fasting panels are acceptable for initial screening but repeat fasting if TG elevated or genetic dyslipidemia suspected.
Concrete Clinical Example
A 45-year-old woman with newly diagnosed GHD (low IGF-1, failed GH stimulation) undergoes lipid panel: LDL-C 130 mg/dL, HDL-C 45 mg/dL, TG 180 mg/dL. Dyslipidemia identified; statin therapy initiated after risk discussion.
