My dog has high liver enzymes. Is Denamarin enough, or is it serious?

I assume when you say liver enzymes you mean ALT? There a few enzymes we look at and elevation in 1 value makes us consider different causes then elevation in another. ALT elevation is caused make liver cell injury and leakage of enzymes in to the bloodstream. As the liver sees all the blood of the body it can be quite a reactive organ. So the question is whether the liver enzyme is up because of something wrong with the liver/vessels to liver themselves (such as an infectious or inflammatory cause (hepatitis) or a shunt (more common in younger dogs)) or something the liver is responding too (toxicity, disease of over organs). Unfortunately all parts of sago palm are toxic to dogs with the seeds (nuts) being most toxic. And it can be quite challenging to know if this is the cause. If it is sago it depends on the degree of ingestion as to how severe the case is. Unfortunately the treatment for this is supportive as you have been doing. The values may continue to increase or hopefully may plateau off and remain mildly elevated or decrease again. Ultrasound will help to rule out other things going on in the abdomen, assess the liver for changes in texture (although a liver can appear normal on an ultrasound and not be functionally normal), and sometimes identify a portosystemic shunt. After the ultrasound then sampling either first by fine needle aspirate or with a biopsy (needed for many cases of hepatitis, some other issues) can be performed. Checking platelets and clotting times should be performed prior to liver sampling in patients whose livers are not normal to decrease the risk of bleeding from sampling. As shunts are more common in younger animals , if this is suspected, additional imaging may be recommended prior to sampling as ultrasound will not identify all shunts. There is also a disorder called microvascular dysplasia that can be found in the liver. This is best diagnosed by liver biopsy and the sample sent to a pathologist who specializes in liver pathology. I hope this has helped and not confused you more. It sounds like your vet has taken the appropriate steps thus far and has recommended the next best steps to try to rule out some other causes.

Hello and thank you for your interesting question. The first thing I would do is schedule another blood work up appointment to look at the liver enzymes in about two weeks after the first sample was taken. If the liver enzymes, specifically ALT, are still elevated, then there is some evidence that there’s been hepatocellular or liver disease or damage. I understand the veterinarian not wanting to test for Cushing’s disease, especially with the age and the lack of symptoms. But if the enzymes are still elevated, I would ask the vet if it would be worthwhile to start a liver protectant daily medication such as Denamarin. This medication given daily could potential he slow the damage to the liver cells and you may never exhibit clinical signs for the remainder of life and this medication has very little side effects. The other thing that you could possibly do if the liver enzymes are elevated used to start a liver protectant diet which is usually a prescription diet that is dispensed that your veterinary clinic. Again, these are two fairly easy, noninvasive ways to protect your pets liver from whatever is causing the cellular damage. I hope I’ve given you some information that helps. Have a great day.

Acute hepatic intoxication is the main suspicion, considering the signs you reported. Denosyl (SAMe) will protect liver cells from further damage and death and it will certainly help to detoxify the liver. It is important to monitor ALT and AST, but clinical improvement is even more important. So i think that he is already improving, since he is eating and surely he is brighter than onset of the signs. It will take time the intoxication will resolve. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. If Sancho's liver values are elevated due to the ingestion of some foreign material, be it a plant or other toxin, & he is eating with no vomiting or diarrhea, your veterinarian may be taking a wait & watch approach. Usually, we will administer emetics ( to induce vomiting ) & an intestinal absorbant such as charcoal if this was an acute issue. But often we do not see these elevations for hours to days after an insult to the liver has occurred. If Sancho is well, rechecking the values in several weeks is prudent. The values may change by this time. If not, we need to see if this is a chronic issue with the liver, or possibly even the gall bladder. Medications may be need ed at this time, including some neutraceuticals such as Sam-e and milk thistle. It is important that you stay in close contact with Sancho's veterinarian for any recommendations. Take care.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Elevated liver enzymes and abnormal liver appearance on ultrasound scan does not necessary mean liver tumour or liver failure. Older dogs often have abnormal liver appearance, which is not related to any serious underlying problem. Liver enzymes level is a measure of 'damage' to liver cells but it is not directly related to prognosis. Again, older dogs often have mild elevation of liver enzymes I would think that the specialist will perform full abdominal scan and possibly take liver samples through a needle - this is commonly performed procedure in dogs with signs of liver disease. Based on the findings of the aspirate, the doctor will recommend further testing or prescribe treatment for Mars.

Hi there. I personally love Denamarin for liver support. denosyl is another go to for my clients. There are also prescription diets like LD from hills science diet that seem to help quite a bit with my long term cases of liver failure. Iv fluids may help as well to flush the liver. I hope this helps and that Bailey gets well soon!

Hello and thank you very much for your question. Because the liver enzymes are increasing, even with liver protectant medications on board, I now believe it is time to perhaps consider a liver biopsy. It is possible that when the original ultrasound was performed, there was a liver specific disease that was not detectable on the ultrasound. So at the very least, I would repeat the ultrasound, as well as try to get a liver biopsy. Make certain that your general practitioner feels confident with this procedure. If they are not, please have them refer you to an internal medicine specialist. Thanks a lot for your question. I hope you find the answer.
