Hindsight: Adipose Tissue and Cardio-Renal Disease



Back in 2000, we were still in the early years of recognizing that fat tissue was an important source of a wide range of molecules that can act locally (paracrine) or at remote organs (endocrine) including blood vessels, the heart, and the kidney.

At that time, Stefan Engeli and I reviewed the emerging literature on this issue in a paper we published in Hormone & Metabolism Research.

In this paper we discussed the potential role of several vasoactive factors, including non-esterified fatty acids, angiotensin II, prostaglandins, and nitric oxide, which were by then all known to be produced and secreted by adipose tissue and could all have important local or paracrine effects.

In addition, we also discussed the central nervous system actions of the adipose tissue-derived hormone leptin, which had been discovered to increase sympathetic nervous system activity, which is typically found to be elevated in obesity. We postulated that enhanced leptin-driven renal sympathetic out-flow, in combination with low atrial natriuretic peptide plasma levels possibly due to over-expression of the natriuretic peptide clearance receptor in adipocytes, may enhance sodium retention and volume expansion, both key features in the pathophysiology of obesity-associated hypertension.

Since then, we have learnt much more about how factors produced in adipose tissue can affect a wide range of physiological functions, and new factors, collectively often called ‘adipokines’, continue to be discovered at a steady pace.

  1. Dear Dr. Sharma,
    Wonderful article! As I write this, my dear brother is laying in a hospital with what they are calling cardiorenal faliure. He is 48 years of age. He also weighs around 450 lbs. Last night he suddenly became weak and started seeing things such as spiders on the wall. I understand in kidney faliure this can happen. Not to bother you with details, I just wanted to say thank you for writing such an informative article. I hope you have a nice weekend.
    Sincerely,
    Dr. Kim
