Objective:
To evaluate baseline plasma cortisol and ACTH concentrations and responses to low-dose ACTH stimulation testing in ill foals.
Design:
Cross-sectional study.
Animals:
58 ill foals.
Procedures:
Baseline cortisol and ACTH concentrations and cortisol concentrations after administration of a low dose of cosyntropin were determined within 6 hours after admission. Foals were assigned to 4 groups on the basis of age (
Results:
Plasma cortisol concentrations 30 and 60 minutes after cosyntropin administration in foals
Conclusions And Clinical Relevance:
Results indicated that most ill foals in the present study population had adequate responses to cosyntropin administration. However, a small subset of ill foals appeared to have dysfunction of the hypothalamic-pituitary-adrenal axis.
