糖尿病是因為胰島素缺乏後,造成體內養分代謝失調,引起以高血糖病為特徵的內分泌性疾病。此疾病多發生於中老年性的畜犬。犬幼年性糖尿病的發病僅佔發病病例數的1.5%。一隻11個月齡的雄性馬爾濟斯犬,因下痢虛脫而求診於國立臺灣大學農學院附設家畜醫院。該病畜的既往歷中長期有多喝、頻尿、食慾極佳但慢性消瘦的情形。經實驗室診斷醫學的檢查發現,該病畜在禁食後仍有持續性高血糖症、尿糖症與尿酮症,因此診斷為犬幼年性糖尿病。經每日胰島素補充後,該病畜的情況已穩定,目前仍繼續接受每日胰島素補充注射與定期回診,以便有效掌握病程的發展。
Diabetes mellitus is an endocrine disorder associated with insulin insufficiency which further causes metabolic imbalance and is characterised by hyperglycaemia. This condition is relatively common in mid-aged dogs. Canine juvenile diabetes mellitus is rare and the prevalence is less than 1.5% of reported cases. One 11 months old, male Maltese was resented to National Taiwan University Veterinary Hospital with chief complaints of diarrhoea and collapsed condition. The dog had an history of chronic polydipsia, polyuria, polyphagia and weight loss. The major laboratory abnormalities of this dog were fasting hyperglycaemia, glycosuria and ketonuria. Juvenile diabetes mellitus was then diagnosed. The dog was stablised using daily insulin replacement and his condition had been gradually improved. The dog was then required to be supplemented with daily insulin and re-examed regularily for managing his diabetic condition.
