Peptic disease and 24-hr patterns of serum gastrin and pepsinogen.

The present study explored the 24-hr variations in serum gastrin and pepsinogen in clinically healthy subjects and in patients with gastric ulcer, duodenal ulcer, and erosive gastroduodenopathy. Time-qualified data were analyzed by means of cosinor procedures. Significant changes in rhythmometric properties were documented in patients with peptic disease when compared to clinically healthy subjects.
