Objectives were to determine the efficacy of empiric treatment with esomeprazole for patients diagnosed with laryngopharyngeal reflux and to determine a treatment paradigm for this patient population.
Prospective study.
Patients were treated with a once-daily dose of 40 mg esomeprazole for 8 weeks. All patients completed a subjective symptom scale (rating laryngeal symptoms and esophageal symptoms) and scoring of flexible fiberoptic examination before treatment and at 4 and 8 weeks of treatment. Nonresponders (<50% reduction in symptom score) were recommended to undergo 24-hour dual-probe pH study while on a regimen of 40 mg esomeprazole once a day, to evaluate for the adequacy of acid suppression.
Thirty patients completed the course of therapy. After 4 weeks of treatment, only 8 of 30 patients had significant improvement of their overall symptoms (8 of 30 improved on laryngeal score, and 11 of 18 improved on esophageal score). At 8 weeks of treatment, 19 of 30 patients had significant improvement on their overall symptoms (18 of 30 on laryngeal score, and 13 of 18 on their esophageal score). Five of seven nonresponders who agreed to be tested had positive findings on pH studies (on medication regimen) at 1 cm above the upper esophageal sphincter. Four of 10 nonresponders improved further after increasing their dosage to 40 mg twice a day. Laryngeal examination scores were statistically improved in responders after 8 weeks of treatment.
Laryngopharyngeal reflux symptoms require at least 8 weeks of treatment for significant improvement in the majority of patients. Esophageal symptoms improve sooner. Nonresponders at a daily dose of 40 mg should be treated with a dosage of 40 mg twice daily, and pH study on medication reserved for nonresponders at this higher dose. Laryngeal examination scores showed mild but statistically significant improvement at 8 weeks of therapy in responders.
确定埃索美拉唑经验性治疗对诊断为喉咽反流患者的疗效,并确定该患者群体的治疗模式。
前瞻性研究。
患者每日服用一次40毫克埃索美拉唑,持续8周。所有患者在治疗前、治疗4周和8周时完成主观症状量表(评估喉部症状和食管症状)以及纤维喉镜检查评分。对无反应者(症状评分降低<50%),建议在每日服用40毫克埃索美拉唑的方案下进行24小时双探头pH研究,以评估抑酸效果。
30名患者完成了治疗疗程。治疗4周后,30名患者中只有8名总体症状有显著改善(30名患者中8名喉部评分改善,18名患者中11名食管评分改善)。治疗8周时,30名患者中有19名总体症状有显著改善(30名患者中18名喉部评分改善,18名患者中13名食管评分改善)。7名同意接受检测的无反应者中有5名在食管上括约肌上方1厘米处的pH研究(在用药方案下)结果呈阳性。10名无反应者中有4名在将剂量增加至每日两次40毫克后进一步改善。治疗8周后,反应者的喉镜检查评分有统计学意义的改善。
对于大多数患者,喉咽反流症状至少需要8周治疗才能有显著改善。食管症状改善更快。每日剂量40毫克的无反应者应改为每日两次40毫克的剂量治疗,对该更高剂量无反应者保留用药时进行pH研究。治疗8周时,反应者的喉镜检查评分显示有轻微但有统计学意义的改善。
