Abstract   Laryngopharyngeal reflux disease (LPR) and gastro-esophageal reflux disease (GERD) occur due to acidic gastric refluxate causing symptoms. Baseline esophageal impedance has been shown to be reduced with prolonged acid exposure. Mean nocturnal baseline impedance (MNBI) is a novel measure that has shown promise in GERD but has not been evaluated in LPR. This study aimed to assess the role of MNBI in LPR and GERD patients. Methods Off-therapy impedance-pH tracings were blindly reviewed for 187 patients previously prospectively allocated clinical diagnoses of LPR (n = 105) or GERD (n = 82). Conventional impedance-pH measures and MNBI were analysed for the two groups. Results MNBI was significantly lower in the distal esophagus in GERD patients compared with LPR (1679 ± 914 vs. 2109 ± 863; p = 0.001). Similarly, in the proximal esophagus, MNBI was lower in GERD than LPR (2289 ± 579 vs. 2541 ± 471; p = 0.001). In the pharynx, MNBI was similar between the two groups (2116 ± 699 vs. 2133 ± 770; p = 0.878). Distal acid exposure time (AET) and the number of distal acid reflux episodes negatively correlated with distal esophageal MNBI (r = −0.195; p = 0.007) and (r = −0.330; p < 0.001) respectively. Conclusion Baseline impedance was reduced in both LPR and GERD at both distal and proximal esophageal measurements, and more severely reduced in GERD. Baseline impedance is strongly and inversely related to acid exposure in the esophagus. Pharyngeal MNBI was not reduced or different between groups. Distal and proximal esophageal MNBI may be useful in diagnosis of LPR as well as GERD.

Abstract   No gold-standard investigation exists for laryngopharyngeal reflux (LPR). Multichannel intraluminal impedance (MII)-pH testing has uncertain utility in LPR. Meanwhile, reflux scintigraphy allows immediate and delayed visualisation of tracer reflux in the esophagus, pharynx, and lungs. The present study aimed to correlate MII-pH and scintigraphic reflux results in patients with primary LPR. Methods Consecutive patients with LPR underwent MII-pH and scintigraphic reflux studies. Abnormal values for MII-pH results were defined from existing literature. MII-pH and scintigraphic data were correlated. Results 105 patients with LPR (31 males (29.5%), median age 60 years (range: 20–87)) were studied. Scintigraphic reflux was seen in the pharynx in 94 (90.4%), and in the proximal esophagus in 94 (90.4%). Delayed scintigraphic contamination of the pharynx was seen in 101 patients (96.2%) and in the lungs of 56 patients (53.3%). Abnormal reflux was seen in the distal esophagus in 12.4%, proximal esophagus in 25.7%, and in the pharynx in 82.9%. Patients with poor scintigraphic clearance had higher Demeester scores (p = 0.043), more proximal reflux episodes (p = 0.046), more distal acid reflux episodes (p = 0.023), and longer bolus clearance times (p = 0.002). Conclusion Reflux scintigraphy has a high yield in LPR patients. Scintigraphic time-activity curves correlated with validated MII-pH results. A high rate of pulmonary microaspiration was found in LPR patients. This study demonstrated a high level of pharyngeal contamination by scintigraphy and MII-pH, which supports the use of digital reflux scintigraphy in diagnosing LPR.

Background:To explore whether combined with TCM based on classical proton pumpinhibitors PPIs therapy can achieve better efficacy for patients withlaryngopharyngeal reflux disease. Methods: There were 150 laryngopharyngeal refluxpatients enrolled and divided into three groups randomly, with 50 cases in each group.Patients in group A were treated with the proton pump inhibitor (PPI) lansoprazole.Patients in group B were treated with lansoprazole combined with Banxia Houpudecoction, and patients in group C were treated with acupuncture treatments and acombination of Chinese and Western medicine. The reflux symptom index (RSI), refluxfinding score (RFS), and quality of life (36 item short form health survey questionnaire)were assessed before and 4 and 8 weeks after treatment. Results: The RSI and RFSscores of the three groups were significantly reduced after treatment (P < 0.001). Ingroup B and C, they were lower than in group A at 8 weeks (P < 0.01). The SF 36 scoreof 3 groups increased after treatment. At both 4 and 8 weeks (P < 0.001), and patientsin groups B and C scored higher than patients in group A (P < 0.001). The total effectiverate of group B and group C was higher than that of group A (P < 0.05). Conclusion:All three treatments have therapeutic effects on the disease, but the efficacy of a PPIalone is not as good as the combined treatments’ efficacies. Moreover, PPI combinedwith Banxia Houpu decoction and/or acupuncture treatment substantially affects lifeimprovement.

Abstract Introduction Several diagnostic methods are currently being used to diagnose LPRD (laryngopharyngeal reflux disease), but have the disadvantage of being invasive, subjective, or expensive. Objectives Our purpose in this study was to investigate the correlation between pepsin and MMP-7 (Matrix Metalloproteinase-7) in pharyngeal secretions of subjects according to RSI (Reflux Symptom Index) score to find out the diagnostic value of MMP-7. Method We recruited 173 subjects aged between 19 and 85 years who completed the RSI scale. All samples were taken after waking up, and the amount of the pepsin and MMP-7 in saliva were measured by means of an enzyme activity assay. Results There was a significant increase of pepsin and MMP-7 activity in the study group with an RSI score of 13 or higher. The sensitivity and specificity of MMP-7 for predicting the possibility of an RSI of 13 or more was higher than that of pepsin. When MMP-7 and pepsin were combined, this sensitivity and specificity increased. Conclusion An enzyme assay of MMP-7 in saliva may be a noninvasive and easy technique for diagnosing LPRD.
