What contributed to the development from this patient’s history of PUD?

In this case scenario, several lifestyle, pharmacological, and physiological factors have contributed to the development of peptic ulcer disease (PUD) in the 65-year-old female patient. The pathogenesis of PUD involves an imbalance between aggressive factors, such as gastric acid and pepsin, and protective mechanisms, including the mucous layer, bicarbonate secretion, mucosal blood flow, and cellular regeneration. Disruption of these protective mechanisms or an increase in aggressive factors can lead to mucosal injury and ulcer formation.

Firstly, her lifestyle habits play a significant role. The patient reports high coffee consumption (6-7 cups daily), caffeine intake known to stimulate gastric acid secretion, which can exacerbate mucosal injury in predisposed individuals (Sonnenberg, 2018). Similarly, smoking history (35 pack-years) contributes to mucosal damage by impairing mucosal blood flow, reducing bicarbonate production, and hindering healing processes within the gastric mucosa (Huang et al., 2019). Smoking also reduces prostaglandin synthesis, which is vital in maintaining mucosal integrity.

Alcohol consumption, albeit moderate (1-2 glasses of wine daily), may further impair mucosal defenses and stimulate acid secretion, aggravating pre-existing mucosal injury (Balsa et al., 2015). Her stressful social situation, including recent separation and the workload of managing two homes, could have caused increased sympathetic activity, leading to elevated gastric acid secretion and stress-related mucosal vulnerability (Yoshikawa & Mizuno, 2017). Stress is a known precipitant for mucosal ischemia and ulcer formation.

Pharmacologic factors also contribute. The patient takes ibuprofen prn for osteoarthritis pain. Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit cyclooxygenase (COX) enzymes, particularly COX-1, which decreases prostaglandin synthesis. Prostaglandins are critical for maintaining gastric mucosal blood flow, stimulating mucus and bicarbonate secretion, and promoting mucosal repair. NSAID-induced inhibition of these prostaglandins significantly increases gastric and duodenal ulcer risk (Lanas et al., 2019).

Her Helicobacter pylori infection, indicated by the positive urease breath test, is a primary contributing factor in the development of PUD. H. pylori damages the mucosal lining directly and causes chronic gastritis, which increases acid secretion and impairs mucosal defense mechanisms (Kusters et al., 2017). The presence of H. pylori is associated with increased risk of ulcer formation, especially in the context of other risk factors like NSAID use and smoking.

Additional elements such as her age, at 65 years, make her more susceptible. Age-related decline in mucosal regenerative capacity and increased likelihood of multiple risk factors interacting raise her vulnerability to ulcer formation and complications (Sung et al., 2020). Furthermore, her comorbid history of chronic sinusitis and osteoarthritis may influence her overall health status and mucosal resilience.

In summary, the development of PUD in this patient results from a combination of increased gastric acid secretion stimulated by lifestyle factors like caffeine and stress, impaired mucosal defense due to NSAID use, smoking, and alcohol, combined with the mucosal damage caused by H. pylori infection. These factors synergistically disturb the delicate balance of the gastric mucosa, leading to ulcer formation.
