Treatment of Feline Diabetes

Marshall, R.D., J.S. Rand, and J.M. Morton, Treatment of newly diagnosed diabetic cats with glargine insulin improves glycaemic control and results in higher probability of remission than protamine zinc and lente insulins. Journal of Feline Medicine & Surgery, 2009. 11(8): p. 683-691.

Diabetes mellitus is a moderately common disease in cats. The most effective and reliable treatment is insulin therapy to achieve glycemic control. The authors’ study compared the glycemic control and remission possibilities in 24 newly diagnosed diabetic cats. The cats were treated twice daily with either glargine, protamine zinc (PZI), or lente insulin along with being fed a low carbohydrate-high protein canned food. The primary finding was that for newly diagnosed diabetic cats, treatment with glargine resulted in a higher probability of remission compared to PZI or lente insulin. Better glycemic control of cats after 17 days of treatment with glargine was noted and based on lower mean blood glucose concentrations. By day 112, 8 of 8 cats treated with glargine achieved remission while 2/8 in the lente group and 3/8 in the PZI group had achieved remission. None of the glargine-treated cats exhibited signs of hypoglycemia while 3 cats in the other groups developed clinically severe hypoglycemia. The study indicates that twice-daily treatment with glargine insulin may deliver better glycemic control and possibility of remission than similar treatment with lente or PZI insulin. The authors note that good glycemic control soon after diagnosis with diabetes mellitus is associated with an increased probability of remission and this should be the goal of insulin therapy. [VT]
