Objective

To evaluate the effect of a high insolublefiber (HF) diet containing 12% cellulose in dry matter and a low insoluble-fiber (LF) diet on control of glycemia in dogs with naturally acquired insulin-dependent diabetes mellitus.

Design

Prospective randomized crossover controlled trial.

Animals

11 dogs with naturally acquired diabetes mellitus.

Procedure

Dogs were fed HF and LF diets for 8 months each in 1 of 2 randomly assigned diet sequences. Caloric intake and insulin treatment were adjusted as needed to maintain stable body weight and control of glycemia, respectively. After a 2-month adaptation period, control of glycemia was evaluated every 6 weeks for 6 months. Variables assessed included serum glucose concentration measured during the preprandial state, blood glycosylated hemoglobin concentration, serum glucose concentration measured every 2 hours for 24 hours beginning at the time of the morning insulin injection, 24-hour mean serum glucose concentration, mean serum glucose concentration fluctuation from the 24-hour mean serum glucose concentration, and 24-hour urinary excretion of glucose.

Results

Significant differences in mean daily caloric intake, body weight, or daily insulin dosage among dogs fed HF and LF diets were not found. Mean preprandial serum glucose concentration, most postprandial serum glucose concentrations, 24-hour mean serum glucose concentration, and 24-hour urinary excretion of glucose were significantly lower in dogs fed the HF diet, compared with the LF diet.

Clinical Implications

Results of this study support feeding of commercially available insoluble fiber diets to dogs with naturally acquired diabetes mellitus. (J Am Vet Med Assoc 1998; 212:380-386)

Summary

Outcome of and complications associated with bilateral adrenalectomy in 8 cats with pituitary-dependent hyperadrenocorticism and bilateral adrenocortical hyperplasia and outcome of and complications associated with unilateral adrenalectomy in 2 cats with adrenocortical tumor (adrenocortical adenoma, 1 cat; adrenocortical carcinoma, 1 cat) and unilateral adrenomegaly were determined. Glucocorticoids were administered to all cats at the time of surgery, and mineralocorticoids were administered to the 8 cats that underwent bilateral adrenalectomy. A ventral midline celiotomy was performed in all cats.

Intraoperative complications did not develop in any cat. Postoperative complications developed in all cats and included abnormal serum electrolyte concentrations (n = 8), skin lacerations (n = 5), pancreatitis (n = 3), hypoglycemia (n = 2), pneumonia (n = 1), and venous thrombosis (n = 1). Three cats died within 5 weeks after surgery of complications associated with sepsis (n = 2) or thromboembolism (n = 1). Clinical signs and physical abnormalities caused by hyperadrenocorticism resolved in the remaining 7 cats 2 to 4 months after adrenalectomy. Insulin treatment was discontinued in 4 of 6 cats with diabetes mellitus. Median survival time for these 7 cats was 12 months (range, 3 to > 30 months). Two cats died of acute adrenocortical insufficiency 3 and 6 months after bilateral adrenalectomy, 2 cats were euthanatized because of chronic renal failure 3 and 12 months after bilateral (n = 1) or unilateral (n = 1) adrenalectomy, and 2 cats were alive 9 and 14 months after bilateral adrenalectomy. In the remaining cat, clinical signs recurred 10 months after the cat had undergone unilateral adrenalectomy. The remaining adrenal gland was found to contain an adrenocortical adenoma and was removed. The cat was doing well when it was lost to follow-up 15 months after the second surgery.
