CRF and omega-3 EPA supplements
(my question is at the bottom of this post)
I found this abstract on PubMed of a recent study of diet for CRF cats -- http://www.ncbi.nlm.nih.gov/entrez/query.fcgi? cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=161 00367&query_hl=8 or (same article) http://tinyurl.com/ac9wq ======== Retrospective study of the survival of cats with acquired chronic renal insufficiency offered different commercial diets. Plantinga EA, Everts H, Kastelein AM, Beynen AC. Department of Nutrition, Faculty of Veterinary Medicine, Utrecht University, The Netherlands. A retrospective study was carried out on the efficacy of seven commercial diets designed to be fed to cats with chronic renal failure. The median survival time of 175 cats that received conventional diets was seven months, whereas the median survival time of 146 cats given one of the seven diets was 16 months. The cats on the most effective of the diets had a median survival time of 23 months and those on the least effective diet had a median survival time of 12 months. The composition of the seven diets was comparable, except that the most effective diet had a particularly high content of eicosapentaenoic acid. PMID: 16100367 [PubMed - indexed for MEDLINE] ================ Does anyone here (Phil? Steve?) know just what level of EPA they used in the study? |

"the most effective of the diets" (median survival time of 23 months) contained 125 mg EPA/100 kcal. (Hills k/d canned). "and those on the least effective diet had a median survival time of 12 months." Walthams low phosphorus/protein dry. None detected! Send me you're email addy. Phil |

One caution here, simply adding EPA to any diet will not yield the same results. Beyond EPA levels, phosphorus levels, potassium levels and a myriad of other nutrients must be considered. While it is easily possible to add EPA to just about anything - doing so will not yield the same results. This is one area where Phil and I disagree. He believes k/d has insufficient protein levels and recommends x/d or g/d. I disagree. There is support for both positions in the literature. Grade 1 Evidence Based Medicine clinical trials supports the use of k/d in CRF cats and clearly shows extended life for cats on k/d. |

Do you think there's any harm in adding some EPA to what she's already getting in her diet? |

Phil Hi Phil, I got your email, I hope you are getting my replies. 1. Looking at the Hills site, it looks like it's 125mg /100 kcal total omega-3s in K/d, they don't list a specific number for EPA. 2. I read over what you sent and it seems like k/d didn't actually produce the best results, rather Leo FKW did. Am I reading something incorrectly? thanks! 5cats |

Looking at the Hills site, it looks like it's 125mg /100 kcal total omega-3s in K/d, they don't list a specific number for EPA. Look at Box 1 in the study- it lists the EPA content of the diets. 2. I read over what you sent and it seems like k/d didn't actually produce the best results, rather Leo FKW did. Am I reading something incorrectly? You're right. I looked over the study again and saw the diets weren't listed in order of efficacy as I thought. I don't think Leo FKW is even available in the US. Phil |

I looked over the study again and saw the diets weren't listed in order of efficacy as I thought. I don't think Leo FKW is even available in the US. If my conversion is right, the EPA in Leo works out to about 197mg of EPA / 100 kcal. My cat is eating somewhere around 200 kcal / day. So theoreticaly, she might need about 400mg EPA a day, with 360mg being the amount in some of the common human supplements. She'd gladly take more, she cleans the plate when it's offered, I'm inclined to indulge her so long as there's no evidence that's it's harmful. (Some of the human studies for EPA/Omega-3 in other diseases were using pretty high levels without apparant ill effect) |

There was a study in the Compendium for Continuing Education for the Practicing Veterinarian by Dr. Jean Hall: Potential Adverse Effects of Long-Term Consumption of (n-3) Fatty Acids. If you can't find it, I'll try to dig it out. |

Neither do I think you would cause great harm as long as what you added was very judicisous. I always fear that people will assume if 1 part of something is good that 2 parts or ten parts must always be even better. I also doubt you would gain anything by adding additional EPA. |
