Abstract

Background: Neutral Protamine Hagedorn human analogue insulin (Humulin N) is commonly used for treatment of canine diabetes mellitus (DM). However, blood glucose and serum insulin concentrations in Humulin N-treated dogs with naturally occurring DM have not been reported. Objective: To investigate blood glucose and serum insulin concentrations in the clinical setting of client-owned Humulin N-treated dogs with naturally occurring, well-regulated DM. Animals: Ten client-owned dogs with naturally occurring, well-regulated DM. Methods: In this clinical study, blood glucose and serum insulin concentrations were measured when dogs received food and insulin (T 0), at approximately every half hour for the next 2 hours, and then approximately every 2 hours for an additional 8 hours. Insulin duration of action was defined as the number of hours from T 0 to the lowest blood glucose concentration and until blood glucose concentration returned to an interpolated value of 70% of basal blood glucose concentration (Glucose b). Results: Mean percent of insulin-induced blood glucose suppression was 49.9 ± 17.1% (median, 46%; range, 29-78%). Insulin duration of action ranged from 4 to 10 hours. Blood glucose concentration increased initially and returned to Glucose b within 0.6-2.2 hours after T 0 in 5 dogs. This initial blood glucose surge then was followed by blood glucose suppression in all 5 dogs. Conclusions and Clinical Importance: These results suggest that Humulin N administered SC twice daily is an effective mode of treatment for dogs with naturally occurring DM. Postprandial hyperglycemia is present in some well-regulated diabetic dogs treated with Humulin N.
