name: endo-statin-therapy-t2d-ckd-stages-1-4
description: This skill suggests statin therapy irrespective of cardiovascular risk score to reduce cardiovascular risk in adults with type 2 diabetes and CKD stages 1-4 or postrenal transplant. Consider when encountering phrases such as "Patient with T2D and CKD stages 1-4", "T2D with renal transplant", or "Assessing statin need in diabetic kidney disease".

# Statin therapy for type 2 diabetes with chronic kidney disease stages 1-4

## STEP 1 — Gather Information
Confirm type 2 diabetes diagnosis; determine CKD stage via eGFR and urine albumin-to-creatinine ratio (stages 1-4) or verify postrenal transplant status; assess for contraindications (pregnancy, active liver disease, hypersensitivity).

## STEP 2 — Rule In / Rule Out
Rule in if patient has T2D with CKD stages 1-4 or postrenal transplant and no contraindications; rule out if patient has end-stage renal disease requiring dialysis (statin initiation not advised per guideline).

## STEP 3 — Classify or Stratify
Select statin based on renal clearance: prefer pitavastatin, pravastatin, or rosuvastatin (partial renal clearance) for dose adjustment; avoid atorvastatin, fluvastatin, lovastatin, simvastatin if hepatic clearance is a concern, though they require no CKD dose adjustment.

## STEP 4 — Decide
Initiate statin therapy at guideline-recommended dose (adjust for CKD except atorvastatin/fluvastatin); schedule lipid panel in 4-12 weeks to assess LDL-C response and adherence.

## Clinical Guardrails / Mimics / Pitfalls
Do not statin in pregnancy or active liver disease; avoid gemfibrozil combination due to increased myopathy risk; watch for CYP3A4-interacting drugs (e.g., clarithromycin) when using simvastatin, lovastatin, or atorvastatin; remember atorvastatin and fluvastatin need no CKD dose adjustment.

## Concrete Clinical Example
A 58-year-old man with T2D, eGFR 45 mL/min/1.73m² (CKD stage 3a), urine ACR 300 mg/g, not on statin, no contraindications. Initiate pravastatin 20 mg daily (dose-adjusted) and recheck LDL-C in 8 weeks.
