Purpose: To determine patients with abnormal sensation in the throat (AST) who would respond to potassium-competitive acid blocker (P-CAB) or serotonin noradrenaline reuptake inhibitor (SNRI) treatment. Methods: AST patients were randomly divided into two groups. Thirty-one and 21 patients received P-CAB and SNRI treatment, respectively. GETS-J, the Japanese version of Glasgow Edinburgh Throat Scales (GETS), consisted of three subscales of throat symptoms (globus sensation, pain/swelling of the throat, and dysphagia) and somatic distress due to the disease, Frequency Scale for the Symptoms of Gastro-esophageal reflux disease (FSSG), and Hospital Anxiety and Depression Scale (HADS) were used before and after treatments. Responders to treatments were defined as those who showed 50% or more decrease in symptom scores or somatic distress. Results: Pre-treatment GETS-J pain/swelling scores and FSSG acid reflux scores were higher in P-CAB responders and decreased after treatment. Receiver operating characteristic curve for pain/swelling subscale had an area under the curve (AUC) of 0.792 to predict P-CAB responders and a score of 11 provided the best combination of sensitivity (62.5%) and specificity (80%). Somatic distress and HADS anxiety scores, but no other GETS-J symptom scores, decreased after SNRI treatment. Pre-treatment globus scores were lower in SNRI responders. AUC value for globus subscale to predict SNRI responders was 0.741 and a score of 6.5 provided the best combination of sensitivity (70%) and specificity (73%). Conclusions: Pain/swelling is a characteristic symptom in AST patients who respond to P-CAB treatment. SNRI treatment would be effective for somatic distress in cases with mild symptoms.
