Objective: Cystatin C (CysC) is a marker for estimation of glomerular filtration rate (GFR) and a predictor of mortality, beyond that provided by GFR. CysC increases with abdominal obesity and insulin resistance independently of GFR, not necessarily due to changes in renal clearance but possibly due to changes in production. Non-GFR determinants of CysC remain poorly defined. GH or thyroid hormone excess (acromegaly and hyperthyroidism) lead to concomitant increases in GFR and...
