2015 ACVIM Forum Research Abstract Program

In conclusion, our data demonstrate that median serum concentrations of T4 and FT4 are lower in sick compared to healthy cats, and these parameters may be inversely correlated with disease severity. Overall, TSH concentrations in sick cats were not significantly different from healthy cats. However, TSH levels in cats may decrease in severe illness, and may occasionally be high, similar to findings in humans with NTI. The objective was to evaluate the use of baseline cortisol to predict the results of ACTH-stimulated cortisol concentration in a population of dogs with pituitary-dependent hyperadrencorticism (PDH) being treated with twice-daily trilostane (Vetoryl Ã’ ).
