Pancreatic insufficiency in celiac disease is not dependent on nutritional status.
To determine the relationship between pancreatic secretory capacity and nutritional status in celiac patients, we studied 52 patients with celiac disease (24 males, 28 females; age range 6-36 months) and 30 healthy control subjects (14 males, 16 females; age range 6-42 months). A secretin-cerulein test was performed on all patients, and levels of serum albumin and plasma fibronectin were assayed. In addition, weight/height ratios were calculated in the celiacs, who were then divided into three groups on this basis, as follows: celiacs with weight/height ratio < or = 3rd percentile; those with weight/height ratio between the 4th and 10th percentiles; and those with weight/height ratio > 10th percentile. There was no significant difference in the duodenal output of chymotrypsin, phospholipase and lipase between these groups. When the total celiac group was compared to control subjects, only lipase levels were significantly lower (P < 0.009). However, subnormal values in one or more pancreatic enzymes were observed in 15/52 celiacs (29%). A residual enzyme activity < 10% of normal secretory capacity, was also found in 4/52 patients. There was no correlation between the output of the various pancreatic enzymes and levels of albumin, fibronectin, and weight/height ratios in the patients. Furthermore, there was no difference in weight/height ratios and levels of albumin and fibronectin between the celiac subjects with pancreatic deficiency and those with normal pancreatic function. We conclude that a mild/moderate pancreatic insufficiency is quite frequent in celiacs, but that it may be completely independent of nutritional status; further studies are therefore required to shed light on its pathogenesis.
