Hi Lizzie
I’m responding to the PM you sent me with info about what supps Gizmo is getting and also his lab results.
First, in regard to the SDMA dropping and the creatinine increasing, it’s important to understand what SDMA tells us about the kidneys, specifically.
In humans, we look at the glomerular filtration rate (GFR) to determine at what percent the kidneys are functioning. The SDMA test was designed as a reflection of the GFR. In cats, as GFR drops below normal (indicating decreased kidney function), the SDMA increases. It is more sensitive to changes in kidney function than creatinine so we see changes in it earlier than in creatinine.
While I’m sure there might be other reasons why the SDMA would decrease and creatinine increase (and you might want to ask your vet to call IDEXX), there are two things I can think of:
- With creatinine and SDMA, there is a 20% biologic variability even within a week. So an SDMA of 16 with a 20% biologic variability, can be anywhere from 13-19. A creatinine of 3.9 can be 3.12-4.68. Think of it like the variability in Glucometer readings.
- If you give any type of medication or supplement that improves the GFR, the SDMA will drop. But you might not see that change in creatinine.
I do find his variability in SDMA from a year ago to now interesting, to say the least but it’s not beyond possible.
Here is the info you provided in your PM:
I have started Potassa-Chews (200 mg each). I am trying to get 4 tablets into him per 24 hr. That was started on 11/09. He loves them and eats them like a treat.
i believe you've been giving him potassium (K) for a while so it’s odd it hasn’t stopped his K from dropping. I’d just continue to follow your vet’s advice and keep an eye on the K. I’m glad he’s not having symptoms of low K but I sure would like to see it above 4.
Vet has called in a compound for Iron but I don't have it yet. I will be calling the pharmacy this morning.
I assume this is due to his low RBCs.
I did start FD chicken hearts this morning - I gave him one whole, re-hydrated and put 1/4 in each of his snacks for the AM cycle. Not sure if I should do one or two per day (1 each cycle).
I don’t know the answer to this. I will refer you to your vet.
Increased B-12 to 1/16 AM/PM mixed with his food. B-Complex was 1/64 AM only and I added it to his PM now (so he is getting 1/64 AM/PM) mixed with his food.
I’m not sure which specific products you are using
, but methyl B12 is usually given are the dose of 250 mcg bid. I’ve only used Jarrows BRight multiB and that is dosed at 1/20 a capsule a day. I’m not sure if the above amounts are teaspoons or fraction of a capsule.
I have also increased the water in his food by a bit. He was getting 5 spoon fulls (distributed) and I increased that to 8 over the 3 snacks/cycle (these are regular eating spoons - not measuring spoons), in addition a small ice cube is added on top of that. The #1 (PS) meal I add marshmallow root mixed with about 1 1/2 Tablespoons of hot water so he gets that water too. He is drinking a bit from his bowls but not much at all.
Excellent. I can’t remember if you are giving subq fluids yet but the general recommendation is to start a small amount of daily fluids when the creatinine goes above 3.5. I know some people give a larger amount every few days but I think cats do better with a smaller amount daily. I would discuss starting subq fluids with the vet if you are not doing them. If you are doing them a couple times a week, I’d discuss increasing to a daily amount. His BUN has really popped up there. I would also suggest Lactated Ringers Soln as it has potassium in it which “might” help his low K levels.
He is itching like crazy. Has been for about a month but has only got worse. I caught him eating litter overnight - not sure how long that has been going on.
I’ve not had to deal with skin allergies and so I don’t want to give you any thoughts about something I have no experience with. Eating litter can be a sign of anemia although he’s still above 30% so it’s a little unusual but ECID
.
Canna Companion is given as needed but no other meds are being used currently. Notes on SS are fairly accurate on what/when I give stuff (except for the Canna). Oh, and the PancraPlus that is mixed with his food (7/8 teaspoon mixed with 26oz of food that is divided into 5 cycles of meals).
I guess I’ve never understood why he’s on pancreatic enzymes without a GI Panel showing he has EPI. Did your vet diagnose him with EPI based on symptoms?
Eating is good and enthusiastic. He has holing his weight (~11#'s). Active (for a 14 yo) and interactive. Purry, happy. He has had an increase in hairballs but I attribute that to the amount of grooming he is doing due to the itching (he will lick then scratch, lick then scratch).
This is great news that he’s eating....so important. You are doing a great job with is P levels.
I hope this is helpful. He’s very lucky to have such a proactive Mom!
