The aim of the present study was to evaluate the effect of a 6-weeks treatment of a CE-marked
combination oral formulation of hyaluronic acid with chondroitin sulphate and aluminium
hydroxide (GERDOFF®), in addition to proton pump inhibitors (PPI) at the standard dose,
versus PPI only, in patients with first diagnosed clinical presentation of extra-esophageal
GERD symptoms.
The investigators verified the reduction of symptoms frequency, using a Likert questionnaire,
and severity, using the Reflux Symptom Index (RSI) questionnaire, to evaluate the proportion
of Responders and Non-Responder patients in these two groups after 6 weeks of treatment,
compared to baseline. Moreover investigators evaluated the persistence of effects of GERDOFF®
+ PPI treatment on extraesophageal symptoms, after a 12-weeks follow up, only in responder
patients.

Primary | Change From Baseline to Visit V4 of the Total Score of RSI Questionnaire | After 6 weeks of treatment, the changes from baseline in the score of Reflux Symptom Index questionnaire were evaluated to verify the effects of treatments on high symptoms. The RSI questionnaire examines 9 items that are scored from 0 to 5, with a higher score that indicates a higher severity of the symptom (range of total score: 0-45). | In the first visit (baseline) and in the visit 4 (after 6 weeks of treatment) | |
Secondary | Total Score of Reflux Symptom Index Questionnaire in All Time-points Assessed | Total score of the Reflux Symptom Index questionnaire assessed in all time-points. The RSI questionnaire examines 9 items, that are scored from 0 to 5, with a higher score that indicates a higher severity of the symptom (range of total score: 0-45). |

Secondary | Score of Throat of the RSI Questionnarie Measured at the Baseline and in the Visit 4 of the RSI Questionnaire Score of Throat Clearance | The Reflux Symptom Index questionnaire examines 9 items, including throat that is score from 0 to 5, with a higher score that indicates a higher severity of the symptom. | At baseline and in the visit 4, after 6 weeks of treatment | |
Secondary | Score of Excess of Mucus in the Throat or Retrosternal Fall of Secretions of the RSI Questionnaire Measured at Baseline and in the Visit 4 | The Reflux Symptom Index questionnaire examines 9 items, including excess of mucus in the throat or retrosternal fall of secretions that is score from 0 to 5, with a higher score that indicates a higher severity of the symptom. | At baseline and in the visit 4, after 6 weeks of treatment | |
Secondary | Score of Difficulty in Swallowing Food, Fluids or Pills of the RSI Questionnaire Measured at Baseline and in the Visit 4 | The Reflux Symptom Index questionnaire examines 9 items, including difficulty in swallowing food, fluids or pills that is score from 0 to 5, with a higher score that indicates a higher severity of the symptom. | At baseline and in the visit 4, after 6 weeks of treatment | |
