Upper GI tract findings in patients with heartburn in whom proton pump inhibitor treatment failed versus those not receiving antireflux treatment

BACKGROUND Failure of proton pump inhibitor (PPI) treatment in patients with heartburn is very common. Because endoscopy is easily accessible, it is commonly used as the first evaluative tool in these patients. OBJECTIVE To compare GERD-related endoscopic and histologic findings in patients with heartburn in whom once-daily PPI therapy failed versus those not receiving antireflux treatment. DESIGN Cross-sectional study. SETTING A Veterans Affairs hospital. PATIENTS Heartburn patients from the GI outpatient clinic. INTERVENTION Recording of endoscopic results. MAIN OUTCOME MEASUREMENTS Endoscopic findings and association between PPI treatment failure and esophageal mucosal injury by using logistic regression models. RESULTS A total of 105 subjects (mean age 54.7 +/- 15.7 years; 71 men, 34 women) were enrolled in the PPI treatment failure group and 91 (mean age 53.4 +/- 15.8 years; 68 men, 23 women) were enrolled in the no-treatment group (P = not significant). Anatomic findings during upper endoscopy were significantly more common in the no-treatment group compared with the PPI treatment failure group (55.2% vs 40.7%, respectively; P = .04). GERD-related findings were significantly more common in the no-treatment group compared with the PPI treatment failure group (erosive esophagitis: 30.8% vs 6.7%, respectively; P < .05). Eosinophilic esophagitis was found in only 0.9% of PPI treatment failure patients. PPI treatment failure was associated with a significantly decreased odds ratio of erosive esophagitis compared with no treatment, adjusted for age, sex, and body mass index (adjusted odds ratio 0.11; 95% CI, 0.04-0.30). CONCLUSIONS Heartburn patients in whom once-daily PPI treatment failed demonstrated a paucity of GERD-related findings compared with those receiving no treatment. Eosinophilic esophagitis was uncommon in PPI therapy failure patients. Upper endoscopy seems to have a very low diagnostic yield in this patient population.

The effect of esomeprazole 20 mg twice daily on acoustic and perception parameters of the voice in laryngopharyngeal reflux.

Background  Randomized, placebo‐controlled studies have failed to demonstrate a significant treatment effect for laryngopharyngeal reflux (LPR) using traditional clinical endpoints. We compared the effect of esomeprazole 20 mg twice daily (b.i.d.) vs placebo on voice and acoustic‐related measures in patients with LPR.

Clinical trial: the effect of Johrei on symptoms of patients with functional chest pain.

Background  Patients with functional chest pain (FCP) represent a therapeutic challenge for practising physicians.

Increased oesophageal acid exposure at the beginning of the recumbent period is primarily a recumbent‐awake phenomenon

Background  A significant increase in oesophageal acid exposure during early recumbent period has been demonstrated.

Reassessment of the Principal Characteristics of Gastroesophageal Reflux During the Recumbent Period Using Integrated Actigraphy-Acquired Information

OBJECTIVES:Characterization of gastroesophageal reflux (GERD) events during the sleep period has been hampered by lack of any patient-friendly technique that allows accurate assessment of sleep duration and awakening time, without confining patients to a sleep laboratory. Our aim was to compare principal reflux characteristics during the upright, recumbent-awake, and recumbent-asleep periods as well as to determine the effect of sleep awakenings on the principal reflux characteristics of the recumbent-asleep period using novel technology that allows integration of recorded actigraphy data into collected pH information.METHODS:Patients with heartburn at least three times a week for the previous 3 months were invited to participate in this study. All participants were evaluated by the demographics and the GERD Symptom Checklist questionnaires. Thereafter, patients underwent ambulatory 24-h esophageal pH monitoring concomitantly with actigraphy. A novel technique was used to superimpose simultaneously recorded raw actigraphy data over pH data, resulting in more accurate information about reflux events during upright, recumbent-awake, recumbent-asleep, and conscious awakening periods as well as the relationship between symptoms and acid reflux events in the aforementioned periods.RESULTS:Thirty-nine subjects (M/F: 26/13, mean age 56.6±14 years) with an abnormal pH test were enrolled into the study. The recumbent period appeared heterogeneous and was clearly divided into recumbent-awake (123.0±20.2 min) and recumbent-asleep (485.6±23.6 min) periods. The percent total time pH<4, the mean number of acid reflux events, and the number of symptoms associated with reflux events were significantly greater in the recumbent-awake as compared with the recumbent-asleep period. The mean duration of an acid reflux event was not different among upright, recumbent-awake, and recumbent-asleep periods. However, short-duration reflux events during the sleep period were associated with conscious awakenings as compared with those during sleep (0.74±0.11 min vs. 1.64±0.3 min, P=0.01).CONCLUSIONS:The recumbent period is divided into recumbent-awake and recumbent-asleep periods. The recumbent-awake period has significantly different principal reflux characteristics than the recumbent-asleep period. Duration of an acid reflux event during the recumbent-asleep period is not uniformly prolonged. Short-duration acid reflux events during the sleep period are likely due to conscious awakenings.

Riser’s reflux – an eye-opening experience

Background  Patients with gastro‐oesophageal reflux disease (GORD) commonly report waking up in the morning with a sour or bitter taste in their mouth. The aim of the study was to compare the prevalence and frequency of acid reflux events prior to and immediately after awakening from sleep in the morning between GORD patients and normal subjects.

The effect of antireflux treatment on patients with gastroesophageal reflux disease undergoing a mental arithmetic stressor.

Background  Acute stress exacerbates heartburn in gastroesophageal reflux disease (GERD) patients by enhancing the perceptual responses to intraesophageal acid. The aim of the study was to determine if antireflux treatment can still alter stimulus response functions to acid in patients undergoing acute stress as compared with placebo.
