Patterns of dyspepsia during the course of duodenal ulcer.
Dyspepsia patterns during the course of duodenal ulcer (DU) were examined in terms of the number of consecutive months that patients experienced dyspepsia either intermittently or continuously, or were dyspepsia-free. The patients (n = 224) were community-based. After ulcer healing, they were evaluated every 3 months for less than or equal to 7 years. Antiulcer agents were prescribed at the physicians' discretion. We analyzed the data on a patient-month basis using a 2-state Markov chain model. The fitted mean number of consecutive months with dyspepsia and the number of months dyspepsia-free were, respectively, 1.7 and 14 in patients on antiulcer agents, and 1.5 and 9 in patients not taking them. On average, patients experienced dyspepsia during 15% of months studied if they were on antiulcer agents, and during 20% of months if not. Regardless of antiulcer therapy, dyspepsia periods were lengthened by age, especially greater than 60 years; male sex; widowhood/divorce/separation; increasing acetaminophen use; and increasing length of time since initial onset of ulcerlike dyspepsia. Dyspepsia-free periods were lengthened by age greater than 70 years, and shortened by widowhood/divorce/separation and increasing cigarette consumption. These results suggest that dyspepsia occurs for less than or equal to 20% of the time in DU patients on about a yearly basis. The least dyspepsia may be expected in patients neither widowed, divorced, nor separated, in whom length of time since the initial onset of ulcerlike dyspepsia does not exceed 7 years, and who neither smoke nor use analgesics regularly.
