Hi everyone,
I am new to this site but I am definitely not new to feline diabetes. My 15 year old kitty (Fat Cat - who is NOT fat and has never been fat) was diagnosed with diabetes October 5, 2011 at the vet with a blood sugar reading of 480. The vet started him on 3U BID of Humulin N and we were to return in one week for a checkup. We returned to the vet October 12 and his blood sugar was 470. The dose was upped to 5U BID for another week. We retured on October 19th for his checkup and his blood sugar was 459. Since Humulin was obviously not working well, I did some research and found out the PZI Bovine insulin was supposed to be the 'superior' insulin in resistant cats due to the amino acid similarities in bovine and cat insulin. So, I had my vet write a script for PZI Insulin (ordered from BCP Pharmeceuticals) starting at 3 U BID begininng October 21st. Spot glucose checks continued to show no improvement (three hours after his morning shot he was still around 330s), so I upped him to 5 U BID on October 28th. Three hours after his 5U shot, his blood sugar was 188. THIS NEVER HAPPEND AGAIN
. October 29th three hours after 5U shot his blood sugar was 281. On October 31st three hours after his 5U shot his blood sugar was 321. Novemeber 2 three hours after his 5U shot his blood sugar was 232. November 3rd three hours after 5U shot his blood sugar was 271. I completed a blood glucose curve on Novemeber 5th (1 week after Fat Cat was started on 5U of PZI BID) and this is what I got:
9:00am (pre-shot glucose) - 386, 5U given
11:00am - 286
1:00pm - 250 (nadir)
3:00pm - 299
5:00pm - 348
9:00pm - 504 (OMG! Upped dose to 6U)
11:45pm - 368 (wanted to make sure 6U didn't cause him to crash)
11/6: 9:00am 5U given
12:00pm - 345
2:30pm - 313
8:30pm - 340
11/7: 9:00am (pre-shot glucose) - 362, 5 U given
12:00pm - 371
11/8: blood sugar three hours after 5 U dose was 340
I am a medical student doing some of my rotations away from home so my mom is in charge of Fat Cat's insulin and spot checks. She works from 1:00pm-9:00pm and that is why he gets his shot at 9am, we check it three hours later at noon, then my mom goes to work.
We had Fat Cat tested for hyperthyroidism because this is one of the insulin-resistant diseases that you can actually treat (acromegaly or cushing disease is a death sentence anyways) and he was found to be slightly HYPOthyroid! We didnt start treating his thyroid problem because I read that giving thyroid replacement can also make it more difficult to regulate diabetes and that some cats have thyroid problems that can be corrected by treating diabetes anyways.
We kept Fat Cat on 6 U of PZI BID for several weeks with still no improvement. Blood sugars three hours after morning injection we starting to climb to the high 300s. I called 1800KITTYDR (Cornell University's Feline Hotline) and spoke to a Vet about all of this since my vet clocked out on this case a long time ago. She suggested switching to Lantus (glargine) BID as she has had a lot of success with 3 units and under for all of her patients. We started Fat Cat on 2U as she directed BID starting December 2nd. On december 4th, he was 279 three hours after his morning dose of 2U. At 3:00pm this same day, he was already back up to 381!! We upped him to 3 units today December 11. His blood sugar three hours after injection was 326. His blood sugar at 2:00pm (5 hours after his 3U injection) was 385.
He is about 8.5lbs now, losing weight
. Pees a lot, is always hungry, and very sleepy. It seems as though he responds to new insulin for two weeks and then he's resistant to it. He is on an all-wet diet, Fancy Feast Classic brand. We have dry kitten food (high protein) available all day long in case he gets hungry. It does have corn gluten in it but it's supposed to be low carb.
Does anyone have any suggestions? My poor sweet pea is continuing to lose weight and is starting to look pretty rough. I'll be home for a month this Wednesday (THANK GOD) so that I can monitor him even closer than before. I say he's 15 because we've had him for 14 years, but he was a stray kitty and we estimate that he was a year old when we got him. So he could be 18-20 for all I know!
Thank you everyone, god bless.
