Salivary alpha-amylase activity and cortisol in horses with acute abdominal disease: a pilot study

BMC Veterinary Research

Table 2 Salivary alpha-amylase (sAA, n = 19) and salivary cortisol (n = 16) coefficients of correlation between Equine acute abdominal pain scales-version 1 (EAAPS-1), heart rate (HR) and respiratory rate (RR), plasma lactate, systemic inflammatory response syndrome (SIRS) score and Serum Amyloid A (SAA)

	sAA (U/L)	P values	Salivary cortisol (μg/dL)	P values
EAAPS-1 score	0.78 (0.38, 0.89)	< 0.001	0.11 (−0.42, 0.58)	0.685
HR (beats/min)	0.22 (−0.27, 0.62)	0.362	0.24 (−0.31, 0.67)	0.370
RR (breaths/min)	0.32 (−0.17, 0.68)	0.184	0.26 (−0.28, 0.68)	0.320
SAA (μg/mL)	0.29 (−0.21, 0.67)	0.235	−0.08 (− 0.54, 0.42)	0.761
Plasma lactate (mmol/L)	0.44 (−0.05, 0.76)	0.069	0.17 (−0.38, 0.64)	0.532
SIRS score	0.49 (0.03, 0.78)	0.032	0.16 (−0.38, 0.62)	0.560

Results are expressed as Spearman r-value (95% confidence interval [CI]). SIRS score (4 point-score) is based on the number of abnormal SIRS criteria among the following: HR > 52 beats/min, RR > 20 breath/min, WBC above or below 5.0–12.5 × 10⁹/L, and temperature below or above 37.0–38.5 °C
