NCT07611162

Brief Summary

The goal of this randomized controlled trial is to compare the effectiveness of different treatments for laryngopharyngeal reflux disease (LPRD) in adult patients with confirmed symptoms and signs of the condition. The main question it aims to answer is: Which treatment (Proton Pump Inhibitors (PPIs), alginate, magaldrate, sucralfate, or diet) leads to the greatest improvement in LPRD symptoms and clinical signs over 3 months? Researchers will compare proton pump inhibitors to alternative medical treatments and dietary management to see which approach is most effective and better tolerated. Participants will:

  • undergo a clinical ENT examination with scoring of reflux signs (RSA)
  • complete symptom questionnaires (RSS) assessing severity, frequency, and impact of symptoms
  • receive one of the study treatments (medication or dietary intervention)
  • be evaluated at baseline and again after 3 months of treatment

DietBEHAVIORAL

Patients are recommended to adhere to a 3-month low-fat, low quick-release sugar, high-protein, alkaline, and plant-based diet. The consumption of fish and meat was authorized but reduced to low-fat fish and meat. The anti-reflux diet considered the exclusion/reduction of additional triggers such as caffeine or theine, spices, tomatoes, fatty, cheese alcohol, and sparkling beverages.

Anti-reflux diet
