why kidney patients won't eat

I'm asked frequently to formulate homemade diets for dogs and cats with chronic kidney disease. The main reason is that they won't eat their prescription diets. While I'm all for trying a homemade food and some pets (usually dogs) accept them better, these patients are trying to tell us something. Switching foods is ultimately a failing solution to the anorexia thing, unless we address the reasons they won't eat.

Here are the top reasons these patients don't eat:
1. Dehydration, dehydration, dehydration - this is most common and occurs because the kidney cannot conserve body water. Dehydration is uncomfortable!
2. Gastrointestinal ulcers (this is due to elevated gastrin levels, a hormone that increases acid secretion). This will result in nausea, vomiting and pain.
3. Uremia (elevated levels of urea nitrogen, creatinine, phosphorus, parathyroid hormone, etc).
4. Anemia (due to the kidney's inability to produce erythropoietin, a hormone that stimulates the bone marrow to make blood precursors)
5. Hypertension which, in people, can cause headaches and dizziness, among other problems.
6. Infection, especially urinary tract infections to which these animals are more susceptible than normal animals
7. Acidemia - high levels of organic acid that accumulate from the metabolism (and inadequate elimination) of protein.
8. Side effects of drugs (and don't forget herbs and nutraceuticals here either)
9. Other conditions present at the same time - especially pancreatitis
10. Food aversions - usually from offering more and more foods when the pet is feeling nauseous.

So that's a lot to stack against a new diet! I have taken to giving my clients this list as a 'checklist' when the appetite goes south. To address the checklist, we usually need to get blood and urine for a biochemical profile, cbc, urinalysis, and urine culture at least. Checking blood pressures on a regular basis is a good idea too. I'm also a proponent of calcitriol, an 'activated' form of Vitamin D that is deficient in kidney patients. I'm told that it does help some animals have a better appetite - we use this if the calcium and phosphorus levels are normal, and preferably after checking parathyroid hormone levels.

I make sure everyone knows how to check for dehydration, and teach them how to give fluids to correct it. Since we are not using endoscopy to look for ulcers during office visits, we may start long term pepcid at any of these visits just in case they are a factor.

My best pet owners bring me a current written list of all their drugs and supplements at every visit too - this is so that I don't rely on my medical records and possibly misunderstand changes that have gone on at home - people sometimes add things or change doses on their own, or run out of drugs and forget to refill them. That list is a big help to all of us so we can check the most recent regimen and analyze the doses for the potential for side effects.

Check list complete? NOW we can try a new diet!

http://www.fda.gov/Safety/Recalls/ucm192404.htm

Diamond Pet Foods Announces Recall of Premium Edge Adult Cat and Premium Edge Hairball Cat Food


Company Contact:
800-977-8797


FOR IMMEDIATE RELEASE - November 27, 2009 - On September 23, Diamond Pet Foods issued a voluntary recall for Premium Edge Finicky Adult Cat and Premium Edge Hairball cat because they have the potential to produce Thiamine Deficiency. Today’s announcement provides additional information from the company’s posted announcement of September 23 when the initial recall information was provided.

Thiamine is essential for cats. Symptoms of deficiency displayed by an affected cat can be gastrointestinal or neurological in nature. At the first stage the cat may show decreased appetite, salivation, vomiting, and weight loss. Later, neurologic signs can develop, which may include ventriflexion (bending towards the floor) of the neck, wobbly walking, circling, falling, and seizures. These ultimately may result in the death of the animal if left untreated. If your cat has consumed the recalled product and has these symptoms, please contact your veterinarian.

The affected products were distributed in Maine, New Hampshire, Vermont, Massachusetts, Connecticut, Rhode Island, New Jersey, Maryland, Delaware, New York, Pennsylvania, Virginia, Alabama, Tennessee, North Carolina, South Carolina, Georgia, Florida.

The affected date codes were RAF0501A22X 18lb. (BB28NOV10), RAF0501A2X 6 lb. (BB28NOV10), RAF0802B12X 18lb (BB30FEB11), RAH0501A22X 18 lb. (BB28NOV10), RAH0501A2X 6lb. (BB28NOV10, BB30NOV10, BB08DEC10)

To date, 21 cases of thiamine deficiency in cats have been reported and confirmed by Diamond. The reports have been confined to the New York and Pennsylvania areas and none have been received since October 19.

Diamond has tested the product and found the cat foods were deficient in thiamine. Samples taken by the FDA indicated that there were additional lots with insufficient levels of thiamine. No other complaints have been reported on any other product manufactured by Diamond Pet Foods.

Consumers who have purchased the affected lots are urged to return it to the place of purchase for a full refund. Consumers with questions may contact the company at 1-800-977-8797, Monday-Friday, 8:00 am to 5:00 pm Central Time.

larger hoof and pig ear recall

FDA NEWS RELEASE
http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm189400.htm

For Immediate Release: Nov. 5, 2009

Media Inquiries: Rita Chappelle, 301-796-4672, rita.chappelle@fda.hhs.gov
Consumer Inquiries: 888-INFO-FDA
FDA Health Alert for Certain Pet Treats Made by Pet Carousel
Products may be contaminated with Salmonella

The U.S. Food and Drug Administration is issuing this health alert to warn consumers not to use Pig Ears and Beef Hooves pet treats manufactured by Pet Carousel because the products may be contaminated with Salmonella. The products were distributed nationwide in both bulk and retail packaging for sale in pet food and retail chain stores. Pet Carousel is based in Sanger, Calif.

The products were manufactured under conditions that facilitate cross-contamination within batches or lots. Although no illnesses associated with these products have been reported, the FDA is advising consumers in possession of these products to not handle or feed them to their pets.

The affected pig ear products were packaged under the brand names Doggie Delight and Pet Carousel. The affected beef hooves were packaged under the brand names Choo Hooves, Dentley’s, Doggie Delight, and Pet Carousel. All sizes and all lots of these products made by Pet Carousel are included in this alert.

During September 2009, the FDA conducted routine testing of pig ears made by Pet Carousel. The test results detected a positive reading for Salmonella. This prompted an FDA inspection of Pet Carousel’s manufacturing facilities. During the inspection, the agency collected additional pet treat samples. Further analysis found Salmonella present in beef hooves, pig ears and in the manufacturing environment.

Salmonella can affect both humans and animals. People handling dry pet food and/or pet treats can become infected with Salmonella, especially if they have not thoroughly washed their hands after having contact with the treats or any surfaces exposed to these products. Consumers should dispose of these products in a safe manner by securing them in a covered trash receptacle.

Healthy people infected with Salmonella may experience some or all of the following symptoms: nausea, vomiting, diarrhea or bloody diarrhea, abdominal cramping and fever. Although rare, Salmonella can result in more serious ailments including arterial infections, endocarditis (inflammation of the lining of the heart), arthritis, muscle pain, eye irritation, and urinary tract symptoms. Consumers exhibiting these signs after having contact with this product should contact their health care provider immediately.

Pets with Salmonella infections may become lethargic and have diarrhea or bloody diarrhea, fever and vomiting. Some pets may only experience a decreased appetite, fever and abdominal pain. Infected, but otherwise healthy pets can be carriers and infect other animals or humans. If your pet has consumed any of the affected products or is experiencing any of these symptoms, contact your veterinarian immediately.

The FDA will continue to investigate this matter to determine the source of the Salmonella contamination and offer updates as appropriate.

Consumers can report complaints about FDA-regulated pet food and pet treat products by calling the consumer complaint coordinator in their area. You can locate the nearest consumer complaint coordinator at:

FDA notice: Beef hooves recalled by PetSmart

PetSmart Voluntarily Recalls Dentley's Beef Hooves
http://www.fda.gov/Safety/Recalls/ucm189296.htm

FOR IMMEDIATE RELEASE -- Phoenix, AZ, Nov 4, 2009 - PetSmart (NASDAQ: PETM) is voluntarily recalling two Dentley's Beef Hoof products for potential salmonella contamination. The products were manufactured by Pet Carousel, Inc. in Sanger, Calif.

The recalled products include only the following types of Dentley's Beef Hooves purchased between Oct. 2, 2009 and Nov. 3, 2009:

Dentley's Bulk Cattle Hoof UPC# 73725703323
Dentley's 10 Pack Beef Hooves UPC# 73725736055

No other products are included in this recall.

The affected products were shipped from the Pet Carousel plant to three PetSmart distribution centers in Ottawa, Ill.; Groveport, Ohio and Newnan, Ga.; and then shipped directly to certain PetSmart stores. Although the affected product was not shipped to every store, as a precautionary measure PetSmart immediately recalled the product from all of its US stores and instituted a register block to prevent any product from being inadvertently scanned and sold. In addition, PetSmart removed the product from the PetSmart.com Web site and notified PetPerks customers with valid e-mail addresses in the PetSmart database who purchased the affected products.

Salmonellosis is an infection with bacteria called salmonella. Most persons infected with salmonella develop diarrhea, fever, and abdominal cramps 12 to 72 hours after infection. The illness usually lasts four to seven days, and most persons recover without treatment. However, in some individuals, the diarrhea may be so severe that the patient needs to be hospitalized. In these patients, the salmonella infection may spread from the intestines to the blood stream, and then to other body sites and can cause death unless the person is treated promptly with antibiotics. The elderly, infants, and those with impaired immune systems are more likely to have a severe illness.

Many dogs do not show clinical signs of salmonella. However, when they do, they often have diarrhea or other signs of systemic infections.

Customers who purchased the recalled products should discontinue use immediately and return the product to any PetSmart store for a complete refund or exchange. Customers who have concerns about their health or their pet's health should consult a medical professional. For additional information about the recall, customers can visit www.petsmartfacts.com, www.petsmart.com ; www.fda.govor contact PetSmart Customer Service at 1-888-839-9638.

More Wysong recalls

http://www.wysong.net/moreinfo.php

MOLD IN PAST EXTRUDED DOG FOODS

-Notice, Explanation, and Response-

Mold has been found in some bags of Wysong dry extruded dog foods manufactured in June, July and August of 2009. No problems have been found or reported in any other Wysong food product.

No products from the following batches should be sold or fed. The affected products are:

Wysong Maintenance™: lot #: 090617
Wysong Maintenance™: lot #: 090624
Wysong Maintenance™: lot #: 090706
Wysong Maintenance™: lot #: 090720
Wysong Maintenance™: lot #: 090817
Wysong Senior™: lot #: 090623
Wysong Senior™: lot #: 090811
Wysong Synorgon™: lot #: 090629
Please contact the point of purchase for an exchange or refund.

Mold spores are in all natural foods. When there is heat, oxygen, and sufficient moisture the spores can bloom into mold. Everyone has experienced this with foods at home.

From what can be determined, the problem with the Wysong foods stems from unusually high heat and humidity on those summer dates. This combined with a malfunctioning moisture checking device is believed to be the cause of the higher moisture and this isolated problem.

All Wysong foods have been tested for mycotoxins and are negative. That is the primary danger in consuming moldy foods. If your pet has consumed the product, the most that could be expected would be loose stool, and this should clear upon changing from these lot numbers.

As noted in the article below, mold is a ubiquitous problem in all packaged foods. Wysong takes many measures to address this:

1. Incoming ingredients are tested for moisture and mycotoxins.
2. Finished products are also tested.
3. Ingredients are used to inhibit mold growth.
4. The NutriPak oxygen and light barrier packaging inhibits aerobic mold growth.
5. Products are nitrogen flushed to remove oxygen.
6. Products are fresh batched.
7. Ingredients are used to help adsorb toxins should they be present.
8. People are advised to refrigerate or freeze unused product, i.e. treat it like any fresh natural food is treated.
9. Most importantly, Dr. Wysong has advised for the past 30 years against feeding any singular food meal after meal. Diets should be rotated and fresh foods incorporated into meal planning in order to decrease the risk of chronic exposure to toxins that may be present in any one food. This information is on all Wysong packaged pet foods.

Premium Edge pet food recalled

I got an email from a veterinarian today, giving notice that Premium Edge cat food is causing thiamine deficiency in cats. Premium Edge is made by Diamond Pet Foods, so naturally I went over to the web page looking for information. None could be found. Yet Christie Keith, over at the petconnection blog, did find some information. She quotes this:

"Diamond Pet Foods has withdrawn from distribution the following date codes of Premium Edge Finicky Adult Cat and Premium Edge Hairball cat: RAF0501A22X 18lb., RAF0501A2X 6 lb., RAH0501A22X 18 lb., RAH0501A2X 6lb. The calls from pet owners or veterinarians regarding this issue have been centered in the Rochester, NY area. All retail outlets shipped the above lots were contacted, asking them to pull the product from the store shelves. The retailers were also asked to contact their customers via email or telephone requesting them to check the date code of the food. However, if you or anyone you know has these date codes of Premium Edge cat food, please return them to your retailer.

Symptoms displayed by an affected cat will be neurological in nature. Any cats fed these date codes that display these symptoms should be immediately taken to a veterinarian.

Product testing proved no contaminants were discovered in the cat food; however the cat foods were deficient in thiamine. Diamond tracked the vitamin premix lot number that was utilized in these particular cat foods and have performed testing on another lot of Premium Edge cat food that used the same vitamin premix, and it was not deficient in thiamine. No other neurological signs have been reported on any other product manufactured by Diamond Pet Foods."

That's great that they have recalled the food. Sure would be nice to see the information on their webpage. I guess the word will get out in the usual guerilla fashion before the company responsibly broadcasts word of a potential problem to cat lovers?

Just tried to find any announcement on the FRONT page of the company's website - still nothing. Interesting.
