Diabetes insipidus was diagnosed in a 6-year-old Holstein-Friesian cow with a history of recurrent fever, ketosis, lymphadenopathy, and inappetence. The diagnosis was based on the clinical findings, response to exogenous vasopressin, and lack of urine concentration in a water deprivation test. The disease gradually regressed over a period of 1 year and did not recur.

In order to clarify if vasopressin (VP) plays a role in the pathophysiology of hyperosmolar nonketotic diabetic coma (HNDC), VP has been infused to diabetic rats and plasma levels of glucose (PG), ketone bodies, FFA and glucagon were determined. High-dose VP infusion (1.2 U/kg/h) caused gradual elevation of PG (60%) and glucagon levels (600%), while ketone bodies showed transient decrease (20%) at 30 min. Under the suppression of endogenous glucagon secretion by constant infusion of somatostatin (100 micrograms/kg/h), high dose VP showed 25% increase in PG levels and 30% reduction of ketone body levels for the subsequent VP infusion for 1.5 hour. Low-dose VP infusion (0.06 U/kg/h) had no hyperglycemic effect, but suppressed ketosis (20%) in the same condition. There were no changes in plasma FFA concentrations, indicating no significant effect of VP on lipolysis. The results indicate that VP often elevated in HNDC may play an important role for the pathophysiology of HNDC through suppression of hepatic ketogenesis.

Patients with diabetes mellitus have higher levels of coagulation factor VIII than the non-diabetic population. This may be a result of poor metabolic control and could contribute to the development of microvascular complications. During ketoacidosis there are acute changes in plasma concentrations of coagulation factors, some of which may be mediated by the rise in vasopressin that occurs. We have investigated the effects of hyperglycaemia without ketosis on some aspects of haemostasis by manipulating blood glucose concentrations using a Biostator. After a 1h run-in period with the blood glucose at 5 mmol/l, the blood glucose was maintained at 5, 15 and 25 mmol/l and maintained for one hour at each level in six male patients with insulin-dependent diabetes. Insulin was infused at 0.25 mu/kg/min. Venous blood samples were taken at the beginning and end of each hour after the run-in period for assays of factor VIII coagulant activity (FVIII:C), von Willebrand factor antigen (vWF:Ag), ristocetin co-factor (FVIIIR:Co), activated partial thromboplastin time (APTT) and vasopressin (aVP). There was a slight, though statistically insignificant fall in median factor VIII:C concentration at each incremental level of increase in blood glucose. Values (at the beginning and end of each hour) were: 1.0 and 1.1 iu/ml at 5 mmol/l; 0.95 and 0.79 iu/ml at 15 mmol/l; and 0.74 and 0.84 iu/ml at 25 mmol. vWF:Ag and FVIIIR:Co were unchanged. Plasma aVP fell slightly from 1.1 to 0.5 pg/ml. The results indicate that high levels of FVIII seen in diabetes are not due to short-term increases in blood glucose and that acute hyperglycaemia does not promote pro-coagulant changes in blood.

Diabetic ketoacidosis is often associated with a temporary increase in protein excretion, but the mechanisms are not completely known. The aim of the present study was to examine the effect of acute experimental moderate ketosis on kidney function and specifically on protein handling using an infusion of 3-hydroxybutyrate in healthy subjects. Seven young healthy males were infused with sodium 3-hydroxybutyrate, the peak blood level attained being 1.96 +/- 0.53 mmol/l (SD). The pH in blood and urine rose significantly from 7.40 +/- 0.03 to 7.45 +/- 0.05 (2p less than 0.01) and from 7.29 +/- 0.79 to 8.51 +/- 0.82 (2p less than 0.01), respectively. Urinary beta-2-microglobulin excretion rose significantly from 0.038 microgram/min x/ divided by 1.9 to 0.082 microgram/min x/ divided by 1.4 (geometric mean x/ divided by tolerance factor) (2p less than 0.01) but urinary albumin excretion was unchanged. No changes were seen in blood pressure, glomerular filtration rate and renal plasma flow. A marked reduction in urine flow from 15 to 5 ml/min was noted, but could not be attributed to changes in plasma arginine-vasopressin, which was reduced before and during infusion due to considerable oral water loading. It is concluded that moderate elevation in blood ketone body levels does not induce albuminuria. It is suggested that the temporary proteinuria present in diabetic ketoacidosis may be related to acidosis per se.
