Effect of furosemide on comprehensive renin-angiotensin-aldosterone system activity of Thoroughbred horses.

Abstract: Furosemide, a commonly used diuretic, activates the renin-angiotensin-aldosterone system (RAAS) in other species. Little is known about RAAS peptide activation in horses. Objective: To evaluate equilibrium analysis as a practical method for RAAS quantification in horses and describe the RAAS response to a single dose of furosemide. We hypothesize that furosemide would cause transient increase in RAAS peptides in horses. Methods: 14 healthy adult thoroughbreds from a university teaching herd. Methods: Horses received either furosemide (1 mg/kg IV) or saline IV in a crossover study design. Protease-inhibited samples were compared with equilibrium analysis samples with Deming regression analysis. Renin-angiotensin-aldosterone system hormones were evaluated at 0, 0.25, 0.5, 4, and 24 hours postadministration, via equilibrium analysis. Values were compared with a mixed effects model. Results: Correlation between protease inhibition and equilibrium analysis was high for angiotensin I peptide (AngI) and angiotensin II peptide (AngII) (r = .92 and .95, respectively). Baseline RAAS peptide concentrations were below the limit of detection except AngII (median, 7.5 [range, 3.5-14.0] pmol/L). Furosemide administration resulted in an increase in AngI (8.0 [0.5-15.5] pmol/L, P = .03), AngII (33.7 [9.6-57.9] pmol/L, P = .0008), angiotensin III peptide (AngIII) (2.9 [0.9-4.9] pmol/L, P = .0005), angiotensin IV peptide (AngIV) (2.0 [0.6-3.4] pmol/L, P = .0005), and angiotensin 1-5 peptide (Ang1-5) (5.6 [1.2-5.9] pmol/L, P = .003) at 4 hours. Differences are reported as difference in the mean (95% confidence interval [CI]). Conclusions: Furosemide produced an increase in hormones associated with both the classical and alternative RAAS pathways. Serum equilibrium analysis is practical for RAAS analysis in horses.

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 study investigates the effects of the diuretic Furosemide on the renin-angiotensin-aldosterone system (RAAS) of Thoroughbred horses, concluding that Furosemide induces an increase in hormones linked with both the traditional and alternate RAAS pathways.

Objectives and Hypothesis

  • The intention of this research was to use equilibrium analysis to quantify the RAAS activity in Thoroughbred horses and to observe the changes that take place after administering a single dosage of Furosemide.
  • The team proposed that the introduction of Furosemide would lead to a short-term surge in RAAS peptide activity within the horses.

Methods

  • Fourteen healthy adult thoroughbreds were used as test subjects. All horses came from a university teaching herd.
  • In a crossover study design, horses were given either an intravenous (IV) dose of Furosemide or saline.
  • Samples treated with protease inhibitors were compared with the equilibrium analysis samples through a Deming regression analysis.
  • At time intervals of 0, 0.25, 0.5, 4 and 24 hours after administration, the hormones of the RAAS were evaluated using equilibrium analysis.
  • A mixed effects model was employed for comparison purposes.

Results

  • There was a high correlation between the results gathered from protease inhibition and equilibrium analysis, especially with regards to the angiotensin I (AngI) and angiotensin II (AngII) peptides.
  • Before the study began, the RAAS peptide levels were below detectable limits, the only identifiable presence being AngII.
  • The application of Furosemide led to a noticeable increase in several peptides after four hours, namely AngI, AngII, angiotensin III (AngIII), angiotensin IV (AngIV) and angiotensin 1-5 (Ang1-5).

Conclusions

  • The researchers summarized that Furosemide does indeed result in an elevation in hormone levels associated with both classical and alternative RAAS pathways.
  • It was also found that serum equilibrium analysis is a practical method for studying RAAS in horses.
