Trace element malabsorption in exocrine pancreatic insufficiency.

This paper presents preliminary results from metabolic balance studies of iron, zinc 
and manganese absorption and retention in children with cystic fibrosis and 
Shwachman's syndrome. Malabsorption of zinc, iron and manganese in exocrine pancreatic 
insufficiency has been demonstrated by these early studies. A possible relationship 
between this and the associated features of CF has been briefly 
discussed, and indicates areas for further research. If such relationships are 
established then some form of trace element supplementation should be considered.
