Association of gastroesophageal reflux disease risk with exacerbations of chronic obstructive pulmonary disease

Gastroesophageal reflux disease (GERD) may be a potential risk factor for exacerbations of chronic obstructive pulmonary disease (COPD). The aim of the present study was to explore the association of GERD risk with exacerbations of COPD. Patients with COPD were consecutively recruited, and COPD Assessment Test (CAT) and Reflux Diagnostic Questionnaire (RDQ) were administered. If the CAT score was 5 points higher than that taken in the stable states, the patient was considered as having exacerbations of COPD. A RDQ score of ≥12 is defined high GERD risk. Univariate and multivariate logistic regression analyses were performed to evaluate the relationship between high GERD risk and exacerbations of COPD. Among 386 patients with COPD, the mean CAT score was 18.3 ± 6.6, and 76 (19.7%) patients had exacerbations during the 1‐year follow‐up. The mean RDQ score was 10.1 ± 4.7, and 132 (34.2%) patients were identified as having high GERD risk. Multivariate logistic regression analyses revealed that the high GERD risk (odds ratio, 2.31; 95% confidence interval, 1.29–3.87) was an independent risk factor of COPD exacerbations. In conclusion, high GERD risk appears to be associated with higher odds for COPD exacerbations.     

Tolerance to H2 receptor antagonist correlates well with the decline in efficacy against gastroesophageal reflux in patients with gastroesophageal reflux disease

BACKGROUND AND AIM: The attenuated antisecretory activity of H2 receptor antagonists (H2RA) during continuous administration is known as the tolerance phenomenon. The authors recently clarified that presence or absence of Helicobacter pylori infection influences the occurrence of the tolerance phenomenon. The aim of this study was to clarify whether tolerance to H2RA is correlated with attenuation of the inhibitory effect against gastroesophageal acid reflux in patients with gastroesophageal reflux disease (GERD). METHODS: Ten male patients with GERD symptoms and abnormal gastroesophageal reflux were investigated by pH monitoring on days 1 and 15 of continuous oral famotidine administration at 20 mg twice daily, and H. pylori infection was examined using the urea breath test. RESULTS: Intragastric and intraesophageal acidity were significantly decreased on the first day of famotidine administration, but then increased during the 15-day administration period in seven patients who were negative for H. pylori. In contrast, the efficacy of famotidine against gastric acid secretion and gastroesophageal acid reflux was not attenuated in three H. pylori-positive patients. The changes in GERD symptoms were correlated with the change in the degree of gastroesophageal reflux. CONCLUSION: The presence or absence of tolerance to H2RA during 15-day administration is correlated with the efficacy for inhibition of gastroesophageal acid reflux.     

Prevalence of gastroesophageal reflux disease and gastroesophageal reflux disease symptoms in Japan

Background and Aim:  Epidemiological studies have shown that 10–48% of people in developed countries have gastroesophageal reflux disease (GERD) symptoms such as heartburn and acid regurgitation. The present study aimed to examine the prevalence of GERD symptoms and GERD in Japanese subjects.
Methods:  A cross-sectional study of Japanese subjects who visited a clinic for a routine health check up was carried out. Subjects were asked to fill out a self-report questionnaire. GERD was defined as the presence of heartburn and/or acid regurgitation at least twice per week.
Results:  Of the 6035 eligible subjects, 2662 (44.1%) reported having had heartburn and/or acid regurgitation during the past year: 124 (2.1%) daily, 275 (4.6%) twice per week, 773 (12.8%) twice per month and 1490 (24.7%) less than twice per month. Three hundred and ninety-nine (6.6%) subjects were diagnosed as having GERD and there was no relationship between the prevalence of GERD and either sex or age. The prevalence of bothersome GERD symptoms was significantly higher in subjects with GERD than in those without GERD.
Conclusion:  Approximately 6.6% of Japanese have GERD and most persons with GERD described heartburn or acid regurgitation as bothersome.

Diagnostic value of dilated intercellular space and histopathologic scores in gastroesophageal reflux disease

The aim of this paper is to investigate the diagnostic value of histopathologic score and the dilated intercellular space (DIS) in patients with gastroesophageal reflux disease (GERD) and functional heartburn (FH). Participants with GERD symptoms including reflux esophagitis, non‐erosive reflux disease (NERD), Barrett's esophagus (BE), functional heartburn (FH), along with a control group with atypical GERD‐like symptom (Sym‐C), and asymptomatic healthy volunteers (H‐C) were administered GERD questionnaire, and subjected to endoscopy and biopsies, as well as 24‐hour pH‐impedance monitoring. Biopsies were evaluated using standards from the 2011 Esohisto Project after Hematoxylin‐Eosin staining. DIS was measured quantitatively under light microscopy. Among the total of 565 participants with qualified biopsy specimens, the mean DIS of the reflux esophagitis (RE) group was significantly wider compared with the other five groups. DIS in patients with GERD‐like symptoms was significantly wider compared with the H‐C. No significant differences were observed between NERD and FH. Results from 24‐hour pH‐impedance monitoring indicated that only the DIS of patients with acid reflux or the amount of acid reflux episodes in patients with DIS was significantly wider compared with patients with nonacid reflux or patients without DIS (P < 0.001). With DIS = 0.9 μm as the cutoff value, the sensitivity and specificity were 62.6% and 54.1%, respectively. Using the total histopathologic score > 3 as the diagnostic criterion, the sensitivity and specificity were 71.7% and 47.4%. DIS is closely associated with GERD and acid reflux. The diagnostic value of histological scores in lower esophagus in GERD is very similar to that of the quantitative measurement of DIS.     

Multichannel intraluminal impedance and pH monitoring in gastroesophageal reflux disease

The role of acid is very well established in the pathogenesis of gastroesophageal reflux disease and acid suppression constitutes the main approach to its medical treatment. With the current frequent use of proton pump inhibitors, we are seeing increasing numbers of patients in whom symptoms persist despite pharmacological acid suppression. Reflux monitoring has been traditionally performed through esophageal pH measurement to detect acid reflux (i.e., drops in esophageal pH to below 4.0). Multichannel intraluminal impedance and pH measurement constitutes an important development in reflux monitoring because, in addition to detecting acid reflux, it enables measurement of nonacid reflux (i.e., with a pH > 4.0, also known as ‘weakly acidic’ for pH > 4 but < 7, or ‘weakly alkaline’ if pH > 7), which may be responsible for symptoms in some patients who are being treated with proton pump inhibitors. This review describes the approach to measuring nonacid reflux, the possible mechanisms responsible for symptoms due to this type of reflux, the clinical importance of this phenomenon and available treatment options; and the role of multichannel intraluminal impedance and pH monitoring in the evaluation of refractory gastroesophageal reflux disease.     

Prevalence and clinical picture of gastroesophageal prolapse in gastroesophageal reflux disease

The prevalence of gastroesophageal (GE) mucosal prolapse in patients with gastroesophageal reflux disease (GERD) was investigated as well as the clinical profile and treatment outcome of these patients. Of the patients who were referred to our service between 1980 and 2008, those patients who received a complete diagnostic work-up, and were successively treated and followed up at our center with interviews, radiology studies, endoscopy, and, when indicated, esophageal manometry and pH recording were selected. The prevalence of GE prolapse in GERD patients was 13.5% (70/516) (40 males and 30 females with a median age of 48, interquartile range 38-57). All patients had dysphagia and reflux symptoms, and 98% (69/70) had epigastric or retrosternal pain. Belching decreased the intensity or resolved the pain in 70% (49/70) of the cases, gross esophagitis was documented in 90% (63/70) of the cases, and hiatus hernias were observed in 62% (43/70) of the cases. GE prolapse in GERD patients was accompanied by more severe pain (P < 0.05) usually associated with belching, more severe esophagitis, and dysphagia (P < 0.05). A fundoplication was offered to 100% of the patients and was accepted by 56% (39/70) (median follow up 60 months, interquartile range 54-72), which included two Collis-Nissen techniques for true short esophagus. Patients who did not accept surgery were medically treated (median follow up 60 months, interquartile range 21-72). Persistent pain was reported in 98% (30/31) of medical cases, belching was reported in 45% (14/31), and GERD symptoms and esophagitis were reported in 81% (25/31). After surgery, pain was resolved in 98% (38/39) of the operative cases, and 79% (31/39) of them were free of GERD symptoms and esophagitis. GE prolapse has a relatively low prevalence in GERD patients. It is characterized by epigastric or retrosternal pain, and the need to belch to attenuate or resolve the pain. The pain is allegedly a result of the mechanical consequences of prolapse of the gastric mucosa into the esophagus.     

Saliva transit in patients with gastroesophageal reflux disease

Saliva is an important factor in the neutralization of the acidity of the refluxed material that comes from the stomach to the esophagus. The impairment of saliva transit from oral cavity to distal esophagus may be one of the causes of esophagitis and symptoms in gastroesophageal reflux disease (GERD). With the scintigraphic method, the transit of 2 mL of artificial saliva was measured in 30 patients with GERD and 26 controls. The patients with GERD had symptoms of heartburn and acid regurgitation, a 24‐hour pH monitoring with more than 4.2% of the time with pH below four, 26 with erosive esophagitis, and four with non‐erosive reflux disease. Fourteen had mild dysphagia for solid foods. Twenty‐one patients had normal esophageal manometry, and nine had ineffective esophageal motility. They were 15 men and 15 women, aged 21–61 years, mean 39 years. The control group had 14 men and 12 women, aged 19–61 years, mean 35 years. The subjects swallowed in the sitting and supine position 2 mL of artificial saliva labeled with 18 MBq of ^99mTechnetium phytate. The time of saliva transit was measured from oral cavity to esophageal‐gastric transition, from proximal esophagus to esophageal‐gastric transition, and the transit through proximal, middle, and distal esophageal body. There was no difference between patients and controls in the time for saliva to go from oral cavity to esophageal‐gastric transition, and from proximal esophagus to esophageal‐gastric transition, in the sitting and supine positions. In distal esophagus in the sitting position, the saliva transit duration was shorter in patients with GERD (3.0 ± 0.8 seconds) than in controls (7.6 ± 1.7 seconds, P = 0.03). In conclusion, the saliva transit from oral cavity to the esophageal‐gastric transition in patients with GERD has the same duration than in controls. Saliva transit through the distal esophageal body is faster in patients with GERD than controls.
