Insights

Chronic kidney disease (CKD) significantly increases mortality risk. The kidneys play a crucial role in regulating adipokines, and impaired renal handling of these factors may drive systemic and cardiovascular diseases.

Area of Science:

  • Nephrology
  • Endocrinology
  • Cardiovascular Medicine

Background:

  • Chronic kidney disease (CKD) is a major risk factor for mortality and cardiovascular events.
  • The kidney's role in systemic diseases, particularly obesity, is increasingly recognized beyond being a target organ.
  • Altered production and clearance of adipokines by visceral adipocytes and the kidney itself are implicated.

Purpose of the Study:

  • To discuss the renal handling of various adipokines.
  • To highlight the kidney's role in the clearance and production of adipokines.
  • To explore the link between CKD, adipokine imbalance, and systemic/cardiovascular disease.

Main Methods:

  • Review of existing data on renal handling of adipokines.
  • Discussion of specific adipokines influenced by kidney function, including insulin, leptin, TGF-Beta, PAI-1, VEGF, angiotensin II, and resistin.
  • Exploration of the mechanistic regulation of renal adipokine handling.

Main Results:

  • The kidney plays a significant role in clearing insulin, leptin, and TGF-Beta.
  • Kidney function can also alter levels of PAI-1, VEGF, angiotensin II, and resistin.
  • The precise mechanisms regulating renal adipokine handling are not well-defined.

Conclusions:

  • The kidney has pivotal roles in regulating circulating adipokines.
  • Altered renal handling of adipokines contributes to an imbalance of factors implicated in progressive cardiovascular and systemic disease.
  • CKD's impact on adipokine regulation is a key factor in its association with adverse health outcomes.
