Chronic kidney disease, or CKD (chronic kidney disease), is a progressive damage to the kidney tissue associated with a loss of function. It is one of the most common age-related diseases in dogs and cats. A cure is not possible. Cats older than 10 years are particularly frequently affected. The onset of kidney failure often dates back years without the owners noticing. New developments in diagnostics and therapy show: The earlier CKD is detected, the better the course can be slowed down and the quality of life maintained.

Diagnostics for chronic kidney disease

In modern diagnostics, one no longer relies only on classic kidney values such as creatinine and urea. Today, the following are also used:

  • SDMA (symmetric dimethylarginine, an early blood marker for kidney filtration)
  • UPC ratio (protein-creatinine ratio in urine to assess abnormal protein loss)
  • Blood pressure

Together with the classification according to the IRIS stages (international system for grading CKD), the disease can be recorded and treated in a much more targeted manner.

Nutrition for chronic kidney disease

There have also been some changes in nutrition. Away from extreme protein reduction towards moderate protein restriction with optimal protein quality, consistent phosphorus reduction and adequate energy supply. A special focus today is on muscle mass (Muscle Condition Score, MCS): Kidney diets should relieve the kidneys without “starving” the animal.

Chronic kidney disease and effects on the cardiovascular system

Another important aspect is the cardiovascular system. CKD and high blood pressure reinforce each other. With the help of the so-called RAAS blockade (drug inhibition of the renin-angiotensin-aldosterone system, e.g. by ACE inhibitor or angiotensin receptor blockers such as telmisartan), blood pressure and protein loss in the urine can be better controlled and both the kidneys and heart can be protected.

In the detailed Guides article in the “Knowledge” menu item, we explain what these developments mean in practice, which examinations are useful for older dogs and cats and what a modern CKD therapy looks like step by step.
