Effect of Doses and Formulations of Bacterial Lipase on
Intestinal Transit in Canine Exocrine Pancreatic Insufficiency
Abstract
- BACKGROUND/AIMS
We determined in canine exocrine pancreatic
insufficiency (EPI) when fed a high fat meal if 1) lipolytic activity
as bacterial lipase (BL) alters intestinal transit (IT) dose dependently,
2) different formulations of BL have different dose responses, 3) correction
of steatorrhea is related to IT.
METHODS
Five dogs underwent ligation of
a high fat meal (fat 43%) was eaten. Powder or microtablet BL were given
at doses ranging from 0 to 400x103 IU. IT of liquid and solid meal markers
was evaluated by total delivery (% total amounts delivered to ileum), AUC
(area under curve), T10 and T4 (minutes for 10% or 4% of ingested markers
to travel from duodenum to ileum).
RESULTS
IT of the solid meal marker
was not related to doses or formulations of BL. However, slowing of IT
of the liquid meal marker was dose, but not formulation dependent
(total delivery, p=0.0004; AUC, p=0.0017; T10, p=0.0245). Greater fat
absorption was associated with slower IT of the liquid but not the solid
meal marker (r2=0.262, p=0.0213).
CONCLUSIONS
In dogs with EPI fed a high
fat diet, slower IT of liquids is dose- but not formulation-dependent and
slowing of IT of liquids correlates with greater fat absorption.
