    Abstract:
    BACKGROUND: Gastroesophageal reflux disease patients demonstrate various pathophysiologic backgrounds. Therefore, a heterogeneous response to proton-pump inhibitor (PPI) treatment can be expected. We investigated the effect of short-term PPI treatment on symptoms and quality of life (QOL) in primary care patients with and without pathologic esophageal acid exposure and in presence or absence of a positive association between symptoms and reflux episodes. STUDY: Seventy-four heartburn patients were categorized into 4 groups according to positive or negative symptom-reflux association, as expressed in symptom index, symptom sensitivity index, and symptom association probability (SAP) and presence or absence of pathologic reflux, defined as esophageal pH<4%>6% of the time (pH+/pH-). Overall and specific reflux symptoms were assessed 1 week before and the last week during a 2-week course of 40-mg esomeprazole daily. The QOL was scored by the Quality of Life in Reflux and Dyspepsia questionnaire 2 weeks before treatment and directly after. RESULTS: Using the SAP to assess symptom-reflux associations, the 4 groups [SAP+pH+(n=40); SAP+pH-(n=12); SAP-pH+(n=10); SAP-pH-(n=10)] had similar demographic characteristics. The SAP-pH- subgroup had the least overall symptom reduction (P<0.01) and in the SAP+pH+ subgroup the greatest heartburn symptom reduction was found (P<0.02). The residual symptom scores on treatment were lowest in SAP+pH+ and highest in SAP-pH- subgroups and relatively high in the SAP+pH-. QOL was severely reduced and SAP-pH- patients had the lowest QOL overall. Similar findings were made using symptom index and symptom sensitivity index. CONCLUSIONS: Symptomatic reflux patients without evidence of reflux disease on a 24-hour pH recording responded less favorably to PPI treatment than patients with a positive symptom-reflux association or with pathologic reflux.
