Evaluation of the effect of glucocorticoid treatment on adrenocortical functions by monitoring endogenous hydrocortisone in horses.

Abstract: Glucocorticoid preparations have anti-inflammatory effects, and are commonly used in the equine clinical setting; however, such treatments can cause a number of side effects. Adrenal insufficiency is an adverse effect induced by the suppression of adrenal function following drug administration. This study aimed to investigate the influence of two glucocorticoid preparations, dexamethasone and hydrocortisone, on adrenocortical function in horses. The usual doses of dexamethasone and hydrocortisone preparations in equine practice were administered intramuscularly to six horses, and peripheral blood was collected at different time points. Concentrations of dexamethasone and hydrocortisone in the plasma, before and after drug administration, were measured using liquid chromatography-tandem mass spectrometry. Considering circadian rhythms in endogenous hydrocortisone levels, hormone concentrations, before and after drug administration, were compared at the same time of the day. Plasma dexamethasone concentrations were below the limit of quantification at 72 hr post-administration. Plasma hydrocortisone concentrations were significantly lower from 1 to 72 hr after administration. After hydrocortisone preparation administration, plasma hydrocortisone levels were significantly higher until 9 hr, and significantly lower at 24 and 48 hr. The suppression rate of endogenous hydrocortisone ranged over 2.2-5.3% with dexamethasone treatment and 17.5-45.7% with hydrocortisone treatment. The study clearly indicated the effects of glucocorticoids on adrenocortical function in horses and provided basic knowledge about the selection and prescription of glucocorticoid preparations and setting the withdrawal times in equine clinical setting.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research focused on the adverse effects of glucocorticoid treatments, specifically dexamethasone and hydrocortisone, on adrenocortical functions in horses. The study measured hormone concentrations in the plasma before and after drug administration to ascertain the extent of adrenal suppression caused by these treatments.

Research Methodology

  • The research involved six horses who were administered typical doses of dexamethasone and hydrocortisone intramuscularly.
  • Peripheral blood was collected from the horses at various intervals.
  • The research team utilized liquid chromatography-tandem mass spectrometry to measure plasma concentrations of dexamethasone and hydrocortisone before and after drug administration.
  • To account for changes in endogenous hydrocortisone levels linked to circadian rhythms, the team compared hormone concentrations at the same time of day before and after drug delivery.

Key Findings

  • At 72 hours post-administration, plasma dexamethasone concentrations were found to be below the limit of quantification.
  • Plasma hydrocortisone concentrations proved significantly lower anywhere from 1 to 72 hours after administration.
  • Plasma hydrocortisone levels were found significantly higher up to 9 hours following hydrocortisone preparation administration, they however were significantly lower at 24 and 48 hours.
  • The suppression rate of endogenous hydrocortisone ranged between 2.2-5.3% with dexamethasone treatment and 17.5-45.7% with hydrocortisone treatment.

Implications of the Study

  • The study offers clear insight into the impact of glucocorticoids on the functionality of the horse’s adrenocortical gland.
  • Another important Layer of understanding provided by these findings is the baseline knowledge they afford regarding the selection and prescription of glucocorticoid preparations in an equine clinical setting.
  • This research can be important in setting withdrawal times in equine clinical treatment, improving health care protocols for horses.
