...and some questions.

Hi all,

I've been lurking here for the past two days and have enjoyed the discussion on ProZinc protocols. While those of you involved in the process may not have something written down yet, I'd love to get some feedback from you as it pertains to my situation.

Let me tell you a bit about Cindy. She is a spayed female Domestic Shorthair. We assume she is approximately 12 years old. She was declawed when she arrived in our lives and at the time, really didn't like any of the other cats in the household. She would bat at them and growl and they returned the favor.

In July of 2008 she had several grand mal seizures. After extensive testing, she was diagnosed with cryptogenic epilepsy and put on 8 mg of phenobarbitol BID. One positive side effect of all this is that she now gets along with almost every other cat in the house!

In March of 2010 she started to have eye problems. She was eventually diagnosed with entropian eyes. She was put on various eye drops and fluid therapy to try to reverse the situation without surgery.

In May of 2010 she was diagnosed with diabetes. We started with 1 unit of Lantus BID. She has been on Lantus since.

Meanwhile, her eye situation was not improving. She would need surgery to resolve the situation. Her eyes were extremely painful and nothing much was helping. Eventually we had to give her prednisone eye drops for the pain. Of course, this didn't help the diabetes. The eye surgeon didn't want to do the surgery until the diabetes was regulated. Clearly, the two situations were incompatible. Eventually we were able to get an internal specialist involved and he recommended the surgery so that 1) her painful eyes would be corrected and 2) we could get her off the steroids.

In the meantime, to try to figure out why the diabetes wasn't regulating, she had an ultrasound which showed an enlarged left atrium and slight inflammation of the lower bowel (potential IBD although she has no other symptoms). Even so, we decided that surgery was really the best option. She had the eye surgery at the end of August 2010. She came out fine and was clearly feeling a lot better. However, there was no change with blood glucose levels.

We have increased from 1 unit BID to 7 units BID with no change whatsoever. Her blood sugar continues to hoover between 350 to 450. The internal specialist wants to move from Lantus to ProZinc.

Some additional information:
There are 11 other cats living in the house with Cindy. One of them is IBD and needs to stay grain and gluten free. His diet consists mainly of duck. Duck diets tend to be a bit higher in fat than most other diets. Since his diet is the most restrictive, everyone else gets to eat duck too. I occassionally add in some turkey or chicken, just to give them some variety.

Originally, the various veterinarians wanted Cindy to have Purina's DM. However, the IBD cat also wanted it and it caused serious flare-ups for him when he was able to steal it. I free feed canned food (EVO Chicken, EVO TUrkey, EVO Duck, Wilderness Duck, Natural Balance Duck) and treat occassionally (not the IBD cat) with EVO's Turkey and Chicken dry. However, I've moved Cindy from the DM to Fancy Feast Classic (Chicken and Turkey varieties).

This is where I'd like your insight. Because she has been so unregulated and clearly non-responsive to the glargine, the internal specialist has suggested we start the ProZinc at 2 units BID. Should we start at 1 instead (as I am assuming is more normal) or is this likely to be a safe number considering her insulin resistance?

I am more familiar with Lantus at the moment. Lantus takes about a week to get any stabilization in BG levels. Based on what I've been reading, it seems that changing doses almost daily is more common with ProZinc? Is this true or am I misunderstanding something?

Thanks for any feedback you can give!
 
Hello and welcome. Unfortunately I'm a little short on time so I will try to address the items more specifically later tonight. Further I'm no good at reading Lantus SSs. Good work on the home testing.

In general one of the first items to address is the diet and to make sure that the kitty is getting all low carb wet food only diet [9% or less as %Kcal] per Janet & Binky's list or other % of Kcal measurements.

Then there are other things too that as well as possible might cause wonky numbers - I have a incomplete list here:
viewtopic.php?p=77223
Is the cat sneaking food from others, or going outdoors and sneaking dry fud?

As you observe, many here change the dose almost daily or even every cycle. ProZinc does not have a storage "shed" like Lantus or Levimir. For the most part [not 100% completely] the dose that you give is gone by 12 hours later. We do use a term here in PZI called "overlap" which some here have noticed with a consistent dose over several cycles, but not all of us experience that with our cats. Overlap is outlined in the PZI Sticky which is good reading.
 
Hello Gator,

I have made significant changes to everyone's diet over the last year or so. They used to have free feed dry food, all too high in carbs and grains. Now they are all getting high protein, low carb wet food diets. I absolutely agree that it has been a big help with a lot of issues, just not Cindy's :(

She rarely, if ever, sneaks food. She doesn't like duck and is pretty happy that she is the only one allowed to eat "her" food. I work from home so whenever she is hungry, she let's me know and I fill up the bowl. The bigger issue is keeping the other 11 out of her food!

I'm familiar with overlap as that is common with Lantus. With the 10 hour duration for ProZinc, I'm suspecting that I'll need to dose her TID eventually. Right now I'm concerned with her starting point. The ProZinc hasn't arrived yet so I'm trying to get all the info I possibly can before I make the switch.

Thanks for replying!
 
Welcome! That is quite an introduction! I'm going to have to let the veterans pick apart your questions, but I do have one comment...

What kind of prednisone was Cindy on? Daily pills, daily liquid, or the long lasting injection?

I only ask because if her surgery to get her off the prednisone was last month, and she was on the long lasting injection, and if she has been on it for several months - there may be quite a bit left in her system. My spreadsheet documents my cat on prednisone without PZ and her on prednisone with PZ, if you think it would be of interest to your situation, please take a look.
 
Welcome Cindy and Cindy's mom!
May we get your name too? you have arrived at a most interesting time here as we are trying to sum up what we now know about pz. i did'nt check but were you an active member of LL? i only ask becuase i'm wondering if you were on their tilly protocol? if you were there i can assume you were since everyone there is.
of course it would be nice to start out on 1unit to allow your cat to adjust to the insulin.
now i will take a look at you ss and see what you've gone thru with that.
the pred. no doubt has interfered with the bg#'s.
We are very happy to have you in our little tribe.
Lori
 
ok, due to lack of wildly colorful chart i'm assuming you were not following protocol? :lol:
 
Hi Michele,

She was on a prednisone eye drops. They weren't long lasting so I am pretty sure all of the pred is out of her system by now. We actually cut her prednisone eye drops to SID in mid-July. She wasn't on predisone at the beginning of her insuline routine and you'll notice that there is no significant difference long term in her numbers. Good thought though!

Thanks!
 
Hi Lori,

Hopefully my name is showing up in my signature! It is Debbie if it isn't. (Not very polite of me not giving my name now is it! :D)

Unfortunately, I have been following protocol as much as I can. Typically, I don't feed her two hours prior to testing and pull the food from everyone for that time period so she can't sneak any. If you notice the curves are pretty stagnant as well. I'd LOVE to get her below 300.

I've done home testing. I've compared the test at home with ones done at the vet with the home test done at the same time and they are about 30 points different each time.

As for the Lantus forum....I started lurking there when Cindy was first diagnosed. I gave it up shortly after as it was way too intense. There was no "give" in peoples' opinions. Since every situation is unique, stating that not doing something a certain way was tantamount to killing your cat just bothered me too much. I did however, avail myself of the plethora of information in the FAQ's and links. I also joined the Yahoo Feline Diabetes forum.
 
totally with you on the intensity of it debbie.
so do you think starting on 1u is acceptable? just as an intro # for cindy.
 
Just to throw my 2cents. I would start with 1 unit. If it really does nothing to the #'s (you can't get below the 250's), then bump up to 1.5 and then to 2. In our experience, the difference between 1 unit and 2 units was HUGE. PZ doesn't have a "shed" as I think Gator mentioned, so it does wear off. It's around 10-12 hours and in our experience, it starts out closer to the 10 hour and moves to the 12 hour the further into the settling in period.

If 2 is too high, you're going to be fighting rebound and wonkiness which gets a wee mind boggling in its inconsistencies and pain in the butt-ness. If you can creep up on the right dose, you'll have much better data to work with. I'm all about the data.
 
I've really been leaning towards starting at 1 unit, just to be safe. The vet really wants to start at 2 because Cindy appears to be so insulin resistant.

Am I understanding ProZinc correctly in that there isn't a time frame required to build up to a "stable" number like there is with Lantus. In other words, the change in BG levels is more immediate?

Thanks everyone for your feedback!
 
well debbie to be perfectly honest we've been debating that lately. i think it is immediate within a day or so. that of course after a week of introducing a new insulin. but many here disagree (agreeably :mrgreen: ) so you are part of our new intense interest in that very subject.
 
LOL! Lucky me! :D

Well the whole thing is kind of a crap shoot anyway to see what works for her. I'll talk to my vet again before I actually start her on the new insulin and see what happens. I've been trying to regulate her for 6 months now...what is a few more?
 
will be interesting to know what vet has to say. do you find him to be pretty knowledgable on FD, becuase frankly we don't often find vets to give very sound advice. please share with us any info he give you and let's review it together if you are'nt adverse to that.
 
Hi Lori,

So far, he seems to be. He is a board certified internal specialist at a large hospital filled with specialists. He is the top internist. He has been very good about not wanting to bring Cindy in unnecessarily and understands the vet stress induced BG spikes. Since Cindy has so many other things going on, there is always the concern that the insulin resistance is due to some obscure issue. He wanted to try a different insulin before moving on to other diagnostic testing.

I'll definitely keep you posted.
 
sounds really good, we should all be so lucky!
must tell you i love the name 'cindy' for a cat. how did she get that? makes me giggle a little. :-D
 
Ahhh! Now that is a story.

It seems that a co-worker of my boyfriend had managed to bamboozle him into helping move a bunch of furniture around. While sitting on the porch with a beer after the move, this cat came galloping up and plopped herself on his lap. The co-worker said in a snide voice "Oh, don't let Prissy bother you. She is aggressive". My boyfriend swears her heard the kitty say "My name isn't Prissy! It is Cindy!"

So this co-worker had a cat he didn't like, called her by a not so nice name and left this poor declawed cat outdoors. She was emaciated and flea ridden. My boyfriend took her home of course and she has been the love of his life (me not-withstanding!) since.

:D
 
OMG love that story...what a happy ending for cindy..and what a great boyfriend.
 
Bookmarked. :mrgreen:

I'm so tired [been shoveling poop - literally - all day], and I said I would give more input tonight... I'm not sure I have the energy. I'm Sorry.
 
HI and Welcome,

I love the story about her name.

And I'm REALLY glad that you jumped in inspite of having read our discussions of the past few days.

I agree, start at 1 unit.

Robin
 
Hi. You have already gotten a lot of good advice and I am not much of an advice giver, so I will just say Welcome! Keep posting and asking questions. This is a great group and they have helped me a lot.
