exocrine pancreatic insufficiency Flashcards
what is it characterised by
reduced secretion of pancreatic enzymes into the duodenum
main clinical manifestations
maldigestion and malnutrition, associated with low circulating levels of micronutrients, fat soluble vitamins and lipoproteins
GI symptoms e.g diarrhoea, abdominal cramps, steatorrhea (excessive amounts of fat in poo - they look looser, smellier and paler, like clay)
what is steatorrhea
excessive amounts of fat in poo
looser, smellier and paler like clay
exocrine pancreatic insufficiency can result from …
○ Chronic pancreatitis
○ Cystic fibrosis
○ Obstructive pancreatic tumours
○ Celiac disease
○ Zollinger-Ellison syndrome
○ GI or pancreatic surgical resection
mainstay of treatment
pancreatic enzyme replacement therapy with pancreatin
Pancreatin contains three main groups of digestive enzymes
Lipase - digests fats
Amylase - digests carbs
Protease - digests proteins
pancreatin needs to be taken with
meals and snacks
Fibrosing colonopathy has been reported in pt with CF taking high dose pancreatic enzyme replacement therapy (in excess of 10,000 units/kg/day of lipase). What are some possible risk factors for this?
in children, boys at higher risk than girls
more severe CF
concomitant use of laxatives
peak age for developing fibrosing colonopathy = 2-8 yrs
what to do if a patient on pancreatin develops new abdominal symptoms, or change in existing abdominal symptoms
review pt to exclude possibility of colonic damage
in patients who continue to experience abdominal symptoms despite high doses of pancreatin, consider a trial of the following drug type, based on limited evidence that acid suppression may improve effectiveness of pancreatin
acid suppressing drugs e.g. PPIs, H2RA
what needs to be routinely assessed? - hint vitamins
Levels of fat soluble vitamins and micronutrients (e.g. zinc and selenium) should be routinely assessed and supplementations advised wherever necessary
Non drug treatment
- dietary advice
- distribute food intake between 3 main meals a day, and 2-3 snacks
- avoid food difficult to digest
- avoid alcohol completely
true or false - pt should stop drinking alcohol completely
true
are reduced fat diets recommended?
no
avoid food that is difficult to digest e.g.
high fibre food
legumes (peas, beans, lentils)
