Dear all,

Thank you for allowing me to join this forum as I am in dire need of information. I have been referred here by the k9diabetes forum.

To start with, let me introduce Ben. Ben is a 10-year old cross-breed, but looks like a toy Manchester Terrier. He weighs 8kg (weighed 10 kg in Dec 2015 when he was diagnosed with diabetes and had lost weight rapidly over the 6 weeks before his diagnosis as he was overweight) and is about 35 cm tall (therefore, not really a toy-sized dog).

We were noticing that Ben was drinking enormous quantities of water and also peeing frequently. We started having house incidents, he had to go out around 3 times / night to pee, and every time there were huge puddles. Ravenous appetite (but he always liked his food). Before his weight loss, he might had fat deposits on neck and shoulders, but he was fat all round.

We went to our vet with these symptoms. He ran blood tests and told us it was diabetes and potentially Cushing's. Blood glucose level was 32 at the time. We started on an insulin for pets, with a minimum dose with the intention of going up gradually. Also changed diet to kibbles for diabetics - Ben only had those kibbles for the first few days. We then had to soak kibbles in broth, add chicken, removed kibbles and gave chicken broccoli, barley, oats - to cut a long story short, come mid-Feb Ben was not eating, we (unwisely) stopped insulin and Ben had a severe case of Diabetic Ketoacidosis, from which he thankfully recovered after 5 days on a drip of IV fluids. Before this glucose levels never seemed to budge (we got 36 and once even HI) and the lowest we got was a short-lived 19. From k9diabetes forum, I got to know we were using a u-100 syringe for pet insulin, when we should have been using a u-40 one.

During this crisis, I urged vet to change Ben's insulin and we switched to one intended for humans (Insulatard). For the time being Ben's diet is regulated (he is eating kibbles for diabetics from another brand and he likes them) and he is getting his insulin twice a day, 5 iu each time. The problem is that Glucose levels go from 26 in the morning, to 14/17 in the afternoon, and again 20 sth in the evening. However, since starting with Insulatard sugar levels never exceed the 26 - 29, and we have gone down to 14 and once even 7. For reasons of geographical location, I am still waiting for a pet glucometre I have ordered from the US and am keen to start home testing to see exactly what is happening during the day.

Now after this long background information, I am coming to the point of my post here, which is the recent results that my vet communicated to me after he tested for Cushing's. However, these tests were taken on the second day of Ben's DKA - when we were really in the eye of the storm.

I do not have the paper with me (vet still has it), but these are the figures communicated over the phone:

TLI +50 Ig/L - values above + 35 indicating pancreatitis or renal insufficiency. The latter is a new occurence, as all previous blood tests showed normal kidney functioning. Ben is having normal blood tests tomorrow to check on kidneys.

Urea normal. Creatinine slightly below normal.

Urine Cortisol: Creatinine ratio 80

LDDS 126.7, 121.9, 15.3 (I hope I got the last figure right)

Alkaline phospatases were high and neurophiles (hope I got the name right) were abnormal too.

Fair enough - We have unregulated diabetes (though not sure if it is unregulated due to failure to find the right dosage and frequency of insulin injections) and we have the blood tests pointing to Cushing's. On the outside, Ben has velvety fur, he is energetic and lively, peeing and drinking subsided to normal levels (sleeps whole night through). There is no pot belly or any skin problems. He is still hungry, but it might be understandable given that he does not get anything outside his feeding time, and he gets only 60 g of kibbles in the morning and the evening.

Coming to my query:

Vet is saying that the course of action now is to stop the insulin and start treatment for adrenal Cushing's and then see what results this will have.

At this point I asked my vet if he knows if the adenoma is adrenal or in the pituitary gland, but he doesn't know.
Ultrasound is unavailable where I live and there are no specialists on Cushing's. Vet said we could so the HDDS, but we will have to stop insulin for two days before the tests.

From your experience,

a) is it wise to do a HDDS and stop insulin, risking another DKA

b) I do not want to second guess the vet (normally he is good and experienced - though he admitted that he doesn't get much cases of canine diabetes), but would it be advisable to ask for a new set of tests? He seemed reluctant when I hinted at it, saying that he always suspected Cushing's from the beginning, there are the alk ph tests, and the urine ratio tests...

c) if insulin is stopped during Cushing's treatment, what if it isn't Cushing's after all? Will there be irreversible side effects?

d) if I delay starting the treatment for two weeks (to get enough time to do my insulin curve properly), will there be any consequences? In other words, does the disease progress rapidly?

Many thanks for any advice you can give me.

Vanessa

Hello and welcome to you and Ben! I apologize that I have only a moment to type right now, but I felt total panic upon reading that your vet is proposing stopping Ben's insulin at this time! Whether or not Ben has Cushing's, his glucose elevation always has to be addressed and managed as well. In the long run, treatment for a dog that is jointly diabetic and Cushinoid can and should allow glucose/insulin levels to stabilize and become more consistently manageable. But it is not a magic wand that is going to make diabetes disappear overnight!

Also, the validity of Cushing's tests that are performed during an acute illness or crisis is always suspect. We have a lot more to talk about, but mainly I want to tell you to continue with the insulin! I cannot imagine what your vet is thinking by suggesting that you stop controlling Ben's diabetes.

Hi Vanessa,

Welcome to you and Ben! OMGoodness, I am sorry that you and dear Ben have a lot going on right now and hopefully when we all put our heads together we'll figure out a safe action plan. I completely agree with Marianne, I believe it would be detrimental to Ben if his insulin was stopped. Ideally you really want his diabetes to be under control before any tests for Cushing's are performed because any non-adrenal illness can create a false positive result on the tests that are used to diagnose Cushing's.

I'm including a excerpt from Dr. Mark Peterson's blog, he is a renown veterinarian that specialize in endocrinology, regarding diagnosing Cushing's in a diabetic dog:
The problem with diabetic dogs is that it's very difficult to make a diagnosis of Cushing's with certainty unless we see cutaneous changes. PU/PD, polyphagia, and high liver values all could be secondary to the diabetes. False-positive test results on a LDDST are very common in dogs with nonadrenal illness, such as diabetes....

And yes, diabetic dogs can get marked hepatomegaly secondary to fat accumulation in the liver. That can lead to a mild-moderate "pot bellied" appearance.

Because it can be very difficult to make a diagnosis of Cushing's syndrome in dogs with diabetes, observation and monitoring is the best course in many of these patients. If Cushing's disease is present, it will be progressive and other signs will develop to make the diagnosis easier to confirm.
Full article can be found here: http://www.endocrinevet.info/2012/01/q-diagnosing-cushings-disease-in-dogs.html

I feel strongly that taking the wait and see approach concerning the Cushing's diagnosis is the best path right now. Getting that blood sugar regulated, I believe, should be top priority.

Hugs, Lori

Thank you for your advice.

I am definitely keeping the insulin and will do my best to get Ben's glucose levels under control. I will work with the people on k9diabetes to see how to go about it best.

The article is very insightful. I will keep it for future reference too.

I will be getting a hard copymof the tests soon, so I will be able to give you more exact details on the figures.

So glad to hear that you are continuing the diabetest treatment (insulin) It is not an either or and we know that he definitely has diabetes due to the crisis he had that required the IV.
Now any test for high cortisol during a crisis isn't reliable as the bodys natural response is to be produce cortisol when something is wrong.

So, I'd say, get him as regulated as you can and see how he does and if symptoms continue. Then we can see if cushings is a factor still to be considered or not.

Your Ben sounds like a very sweet boy, patient while his conditions are sorted out. Just want to tell you how we have faired with diabeties.

My mix, 16 year old boy, Andy, has had diabeties for 5 years. He's a cock-a-poo, about 20 lbs. I believe the reason he has done so well with the diabietes is two-fold. Humlin medication, twice daily (currently 8 units). And his diet: Hills Prescription Diet Digestive/Weight/Glucose Management. Canned food, he loves it and it has certainly played a big part in his longevity. For treats he gets diabetic cookies from Old Dog Cookie Company - they ship. He has three brothers (various breeds!) so getting treats is a big part of every day. These cookies are specially formulated to be diabetic friendly.

Lastly, if at all possible, find a vet who has a lot of experience with the diabetes. It's so important to have someone guiding you with as much experience as possible.

Best of luck

Yes, Ben is truly a sweet dog with a heart of gold!
I hate to think that our mistakes might have cost him his life!
We had good news on Monday - sugar levels were 6.7. There was no more testing since. I am now going to do a curve tomorrow (with a loaned pet glucose meter - mine is still on the way).
I am worried that on Monday, while glucose levels were that low, Ben's alk ph were 759, when normal range is 24 - 212, and Alt was 138, with a 10 - 100 normal range:(
Now the first step in my plan of action is the curve.
To Mom2kdnh - I hope that the strict insulin and feeding regime will work for us too! There is nothing that I wish more than to give Ben the best possible life.
I will certainly consider diabetic treats once his glucose levels are stable. 62 gr per meal is too little, but I am really following the plan to the letter to leave no room for mistakes. I checked the website for biscuits - I will see if they deliver overseas.
Unfortunately, there are no experts here on diabetics and Cushing's, which is why k9diabetics and k9cushings have been a Godsend for me! Thank you for all your help!

So glad to hear that sugar levels where good.

How did the curve go?

something like milk thistle and/or sam-e might help with the liver enzymes. They are both supplements that are liver supportive.

Dear all,

I finally managed to get a curve! Ben cooperated all the way through. I took blood from the base of the tail, and Ben hardly noticed (people from k9diabetes helped me with advice too!).

I am copying the figures here as I cannot find a way of copying the curve proper here. I have converted the values to US ones already.

Time of day - Glucose Levels

7.15 - 129.6
9.45 - 82.8
11.5 - 68.4
14.2 - 156.6
16.2 - 140.4
19.2 - 154.8

We had a walk at 7.00 (10 mins), 8.30 (30 mins), noon (10 mins), 16.30 (20 minutes) and 19.45 (10 mins).

Insulin injection was at 7.30 am and 7.30 pm, preceded immediately by feeding, in our case, 0.14 pounds of Royal Canin for diabetics for each meal (62 gr). We are still using Insulatard, 5iu x2 / day.

I am suspecting the lower figures might have been an error, as Ben was not hypo at the time, though he looked a bit tired. Still, I am now eliminating the long morning walk and will try doing it in the afternoon, where we seem to have the higher figures.

I will be repeating the curve once I get my own glucometre (hopefully next week!).

I still have not managed to come to the bottom of the Cushing's issue. All I can conclude now is that the insulin is working, but I am not sure if it is so because of a high insulin dose (is it excessive in relation to his weight??).

Peeing and drinking back to normal.

There is also fur growing on the shaved patches.

I am going today to the vet's with the curve. I will ask about milk thistle and also about treats.

This is good that fur is regrowing in the shaved patches and also that peeing and drinking are back to normal. Seems you are on the right track!
