Clinical and pathophysiological consequences of on-demand treatment with PPI in endoscopy-negative reflux disease. Is rebound hypersecretion of acid a problem?
Rebound acid hypersecretion is probably an infrequent problem in on-demand treatment with PPI in patients with endoscopy-negative reflux disease. A significant increase in p-CgA and s-gastrin was found after 6 months treatment. Fourteen days after withdrawal, CgA and gastrin returned to pretreatment levels. Overall, no aggravation of symptoms was found, but 1/3 experienced increased symptoms.
Any impact of "anxiety" on post-ACS outcome appears to be influenced by the clinical sub-type. The seemingly paradoxical finding that GAD might improve outcome may reflect "apprehensive worrying" being constructive, by improving self-management of the individual's cardiac problems.
