RESUMEN
The food intake of 40 male patients with chronic pancreatitis followed up at our center for > or = 10 y were compared with that of 75 healthy control subjects. Patients had significantly lower anthropometric values and serum triacylglycerol and cholesterol concentrations than control subjects (P < 0.001). Subjects with pancreatitis had higher carbohydrate and energy intakes than control subjects but no significant differences were observed in protein, fat, fiber, or cholesterol intakes. The results show that although those with chronic pancreatitis consumed carbohydrates with a more balanced variety of nutrients, they were thinner and had lower serum lipid concentrations, which suggests that they had latent digestion disorders or malabsorption.

BACKGROUND: Few data are available on disturbed gastric emptying in patients with coeliac disease. The aims of the study were to investigate (a) the presence of delayed gastric emptying: (b) the acute effect on gastric emptying of gliadin; and (c) the effect of jejunal recovery on gastric emptying of meals with or without gluten in such patients. METHODS: We measured gastric emptying of two meals in 16 patients with coeliac disease; one meal contained gliadin. Results were compared with those obtained in 24 controls. In 12 patients, both measurements were repeated after mucosal recovery. Statistical analysis was performed using the analysis of variance for repeated measurements and Student's t test. Mean +/- 1 s(mean) (standard error of the mean) are shown. RESULTS: No difference was found in fasting and in maximal antral sections after the two meals. On entry, gastric emptying was significantly (P < 0.001) delayed compared to controls both after the meal containing gluten (326.9 +/- 12.4 min versus controls 213.5 +/- 11.5) and after the gluten-free meal (315.3 +/- 16.7 min). After jejunal recovery, emptying of the meal containing gluten remained unchanged (337 +/- 18.9 min), whereas emptying of the gluten-free meal was significantly shortened (280.6 +/- 10.5 min; P < 0.001). CONCLUSIONS: In coeliac disease there is an impairment of gastric emptying which is at least partially reversible. This suggests either an immunological disorder or that unabsorbed meal constituents are responsible for an ileal-brake effect.
