To characterize gastroesophageal reflux (GER) by multiple esophageal pH-impedance (MII-pH) in children with idiopathic bronchiectasis (BC); to assess its relation with respiratory function through spirometry; to analyze the accuracy of a morpho-functional high-resolution computed tomography (HRCT) scoring system in predicting MIIpH results. Methods: MII-pH parameters in children with respiratory symptoms, with and without BC were compared. In children with BC spirometry was performed and HRCT score was calculated by evaluating in each lung lobe: 1. bronchiectasis-peribronchial wall thickening, 2. mucous plugging, 3. abscess-sacculations, 4. consolidations, 5. others. HRCT score was related to MII-pH results. HRCT score accuracy in predicting pathological MII-pH was evaluated by ROC curve. Results: Twenty children with BC (mean age 8.25 ± 5 years, 12 males) and 20 without BC (mean age 8 ± 5.1 years; p: 0.2918, 15 males p: 0.1577) were enrolled. No significant differences were found in any MII-pH parameter between the two groups. Among BC children, 7/20 had a pathological MIIpH and didn’t show any difference in respiratory function compared to those without GER. There were no significant correlation between HRCT score and MII-pH parameters but a direct (not significant) correlation with reflux index (r=0.240 p=0.307), acid refluxes (r=0.022 p=0.925) and symptom index/symptom association probability (r=0.041 p=0.865). The mean value of the HRCT score in children with BC with pathological MII-pH was higher than in the ones with normal MIIpH (6.571 vs. 4.846, p=0.0929). The Area under the Curve was 0.736. A HRCT score of 4 5 and 7 5 were associated with a negative predictive value of 86.5% and a positive predictive value of 75% respectively. Conclusion: children with idiopathic BC had no distinct GER features. HRCT scoring system showed a moderate accuracy in predicting MII-pH results and a value ≤ 4.5 is rarely associated with a pathological MII-pH.
