Contrary to the expectation FDA hopes you will have, as a pet owner, trusting FDA to investigate this possible link to heart disease and relying on their public conclusions would be foolish.
Although DCM in some dogs without any apparent taurine deficiency appears to be reversible with a change in diet, with or without taurine supplementation, no cause has thus far been identified for non-taurine deficiency—associated DCM.
Whereas myocardial function did not return to normal in most dogs, it did improve enough to allow discontinuation of cardiovascular drug therapy and to maintain a normal quality of life for months to years.
Therefore, a requirement for dietary taurine has not been generally recognized in dogs. Let us avoid this type of reaction and instead look at the evidence: All dogs were successfully weaned off furosemide, an angiotensin converting enzyme inhibitor, and digoxin once an echocardiographic response was identified.
The undigested complexes travel to the large intestine and provide an intestinal environment that favors increased numbers of taurine-degrading bacteria. The complexity of pet food manufacturing is often underestimated. Properties and distribution of mammalian L-cysteine sulfinic carboxylases Jacobsen, J.
Retinal degeneration associated with taurine deficiency in the cat Hayes, K. Recently, however, we have heard from veterinary cardiologists who had an impression that they were diagnosing DCM in Golden Retrievers at higher rates than expected and in dogs of breeds typically not thought to be prone to this condition.
Back to the top Collaboration When unprecedented events such as these occur, the FDA often consults with stakeholders across the animal health community to help fill any knowledge gaps that may help inform its investigation.
These factors could affect taurine status in three ways: Taurine-deficiency DCM has been around for a while in dogs and continues to need study before making definitive conclusions about one or more specific dietary causes.
Or, the apparent association may be spurious. Although the exact underlying cause is not known, it appears that some breeds have either a naturally occurring higher requirement for taurine or a metabolic abnormality that affects their taurine synthesis or utilization.
A variety of diseases can affect any of these parts. Back to the top Diet Information from Reported Cases Review of the canine reports shows that the majority of reports were for dry dog food formulations, but raw food, semi-moist food, and wet food were also represented.
Effects of dietary fat and L-carnitine on plasma and whole blood taurine concentrations and cardiac function in healthy dogs fed protein-restricted diets Sanderson, S. In addition, extensive testing is needed on an ongoing basis to ensure rigorous quality control. These factors are not yet fully understood for dogs but we can make a few guesses.
Beneficial effect of taurine in rabbits with chronic congestive heart failure Takihara, K.
Cardiomyopathies are a group of diseases that affect the heart muscle, and DCM is one form of this type of problem. Stern are piecing together data to get a clearer picture about this problem.
However, in certain dogs, it may take even longer for improvements to be apparent echocardiographically. Cardiac cachexia muscle loss occurs early in patients with CHF and should be detected at its mildest stages, when interventions are more likely to be successful.taurine deficiency and subsequent cardiac disease [3,5–9].
Several studies and case reports have established an association between canine taurine deficiency and dietary factors [5–8,16]. For owners who elect to feed a homemade diet, it is critical to have the homemade diet carefully formulated by a veterinary nutritionist to avoid severe nutrient imbalances, especially in young.
Darcy Adin, Teresa C. DeFrancesco, Bruce Keene, Sandra Tou, Kathryn Meurs, Clarke Atkins, Brent Aona, Kari Kurtz, Lara Barron and Korinn Saker, Echocardiographic phenotype of canine dilated cardiomyopathy differs based on diet type, Journal of Veterinary Cardiology, /robadarocker.com, 21, (), ().Cited by: University of California, Davis, veterinarians led a team that has found a link between some popular grain-free, legume-rich dog diets and a type of nutritional deficiency and canine heart disease known as taurine-deficient dilated cardiomyopathy.
Taurine and Carnitine in Canine Cardiomyopathy Although few studies of the prevalence of DCM in the overall population of dogs have been reported, estimates range from % to % [5,6].
Only degenerative valvular disease and, in some regions of the world, heartworm infection are more common causes of cardiac morbidity and mortality in robadarocker.com: Sanderson, Sherry Lynn.
The diet should be started from the onset of signs of cardiac disease.
