T. Spillmann et al., Serum feline trypsin-like immunoreactivity following administration of ceruletide to healthy cats, AM J VET RE, 61(8), 2000, pp. 925-927
Objective - To determine changes in serum feline trypsin-like immunoreactiv
ity (fTLI) in response to administration of ceruletide to healthy cats,
Animals - 11 healthy cats.
Procedures - Serum fTLI was determined, using a radioimmunoassay, before an
d 10, 20, 30, 40, and 50 minutes after IM administration of ceruletide (0.3
mg/kg [0.14 mg/lb]).
Results - Mean +/- SD baseline serum fTLI was 23.1 +/- 4.1 mg/L. There was
a statistically significant, but clinically unimportant, increase in serum
fTLI 10 and 30 minutes after ceruletide administration.
Conclusions and Clinical Relevance - In healthy cats, administration of cer
uletide induced a statistically significant, but clinically unimportant, in
crease in serum fTLI. Whether responses in cats with exocrine pancreatic di
sorders would be different is unknown, but results suggest that a ceruletid
e stimulation test would likely not be useful for differentiating between h
ealthy cats and cats with subclinical chronic exocrine pancreatic disorders
