Asthma and gastroesophageal reflux

Area of Science:

• Gastroenterology and Pulmonology
• Clinical Medicine
• Pathophysiology

Background:

• Gastroesophageal reflux (GER) and asthma are prevalent conditions, frequently co-occurring in patients.
• Evidence from animal studies, epidemiology, and clinical data suggests a link between GER and asthma pathogenesis.
• Patients with coexisting GER and asthma may experience nocturnal asthma exacerbations or postprandial pulmonary symptom worsening.

Purpose of the Study:

• To explore the relationship between gastroesophageal reflux and asthma.
• To evaluate diagnostic and treatment strategies for patients with coexisting GER and asthma.
• To determine the cost-effectiveness of initial treatment approaches for this patient population.

Main Methods:

• Review of animal experiments, epidemiologic data, and clinical studies.
• Assessment of classic GER symptoms and atypical presentations in asthma patients.
• Evaluation of empiric acid-suppressive therapy as a primary treatment modality.
• Consideration of diagnostic studies for complicated reflux disease.
• Analysis of long-term medical therapy versus surgical interventions like fundoplication.

Main Results:

• Empiric acid-suppressive therapy is the most cost-effective initial approach for asthmatic patients with classic GER symptoms, particularly when asthma is poorly controlled.
• Persistent symptoms or signs of complicated GER (e.g., dysphagia) warrant further diagnostic evaluation.
• Medical therapy is generally recommended for long-term management.
• Laparoscopic fundoplication is a viable alternative for selected young patients with documented reflux and symptom response to acid suppression.

Conclusions:

• Gastroesophageal reflux is a significant factor in asthma management.
• Empiric acid-suppressive treatment offers a cost-effective first-line strategy for GER in asthma.
• Long-term medical management is preferred, with surgical options available for specific patient profiles.
