10 Reduced exocrine
secretions
Exocrine pancreatic insufficiency
Description of condition
Exocrine pancreatic insufficiency is characterised by reduced
secretion of pancreatic enzymes into the duodenum.
The main clinical manifestations are maldigestion and
malnutrition, associated with low circulating levels of
micronutrients, fat-soluble vitamins and lipoproteins.
Patients also present with gastro-intestinal symptoms such
as diarrhoea, abdominal cramps and steatorrhoea.
Exocrine pancreatic insufficiency can result from chronic
pancreatitis, cystic fibrosis, obstructive pancreatic tumours,
coeliac disease, Zollinger-Ellison syndrome, and gastro-
intestinal or pancreatic surgical resection.
Aims of treatment
The aim of treatment is to relieve gastro-intestinal
symptoms and to achieve a normal nutritional status.
Drug treatment
Pancreatic enzyme replacement therapy with pancreatin
below is the mainstay of treatment for exocrine pancreatic
insufficiency.
Pancreatin contains the three main groups of digestive
enzymes: lipase, amylase and protease. These enzymes
respectively digest fats, carbohydrates and proteins into
their basic components so that they can be absorbed and
utilised by the body. g Pancreatin should be administered
with meals and snacks. The dose should be adjusted, as
necessary, to the lowest effective dose according to the
symptoms of maldigestion and malabsorption. h
Fibrosing colonopathy has been reported in patients with
cystic fibrosis taking high dose pancreatic enzyme
replacement therapy (in excess of 10 000 units/kg/day of
lipase). Possible risk factors are gender (in children, boys are
at greater risk than girls), more severe cystic fibrosis, and
concomitant use of laxatives. The peak age for developing
fibrosing colonopathy is between 2 and 8 years.
Manufacturers of Pancrease HL ® and Nutrizym 22 ®
recommend that the total dose of pancreatin used in
patients with cystic fibrosis should not usually exceed
10 000 units/kg/day of lipase. Manufacturers of pancreatin
recommend that if a patient taking pancreatin develops new
abdominal symptoms (or any change in existing abdominal
symptoms) the patient should be reviewed to exclude the
possibility of colonic damage.
There is limited evidence that acid suppression may
improve the effectiveness of pancreatin. g Acid-
suppressing drugs (proton pump inhibitors or H2-receptor
antagonists) may be trialled in patients who continue to
experience symptoms despite high doses of pancreatin.
Levels of fat-soluble vitamins and micronutrients (such as
zinc and selenium) should be routinely assessed and
supplementation advised whenever necessary. h

Non-drug treatment
g Dietary advice should be provided. Food intake should
be distributed between three main meals per day, and two or
three snacks. Food that is difficult to digest should be
avoided, such as legumes (peas, beans, lentils) and high-fibre
foods. Alcohol should be avoided completely. Reduced fat
diets are not recommended. h
Medium-chain triglycerides (see MCT oil, in Borderline
substances), which are directly absorbed by the intestinal
mucosa, were thought to be useful in some patients.
However evidence has shown that MCT-enriched
preparations offer no advantage over a normal balanced diet.
