The Natural History of Chronic Unexplained Gastrointestinal Disorders and Gastroesophageal Reflux During 20 Years: A US Population-Based Study.

ABSTRACT:

Objective

To explore the natural history of chronic unexplained gastrointestinal (GI) symptoms and to determine the longitudinal trends of prevalence during a 20-year period in a single US community.

Methods

Between January 1, 1990, and December 31, 2009, valid self-report questionnaires of GI symptoms were mailed to randomly selected cohorts of a community. The study used respondents who answered questions on 1 or more of 3 surveys (initial, 1990-1992; second, 2003-2004; and third, 2008-2009). The trends of prevalence of GI symptoms over time were analyzed in responders who completed 3 surveys, and the natural history or transition was evaluated.

Results

The overall prevalence of major symptom groupings including gastroesophageal reflux disease was consistent among residents in a community on 3 survey time points (1990-1992, 2003-2004, and 2008-2009). The transitions of GI symptoms were common in 228 patients who responded to all 3 surveys; only 29% had the same symptom category in 3 surveys; otherwise, symptoms changed over time, resolving, recurring, or transitioning to another disorder. Observed proportions of symptom transitions were significantly different from expected during 20 years (P<.001). Higher non-GI somatic symptom scores were significantly associated with both symptom transitions (odds ratio, 3.9; 95% CI, 1.38 to 10.77) and having sustained symptoms (odds ratio, 12.7; 95% CI, 4.62 to 34.90).

Conclusion

The overall population prevalence of chronic unexplained GI symptoms is stable, but in individuals, transitions seem to be the rule. As these various GI syndromes appear to be so intimately interconnected, the common underlying pathogenesis may account for a major subgroup of chronic unexplained GI disorders.

Project description:Dental erosion (DE), one of oral hard tissue diseases, is one of the extraoesophageal symptoms defined as the Montreal Definition and Classification of gastroesophageal reflux disease (GERD). However, no study evaluated the relationship between GERD and oral soft tissues. We hypothesized that oral soft tissue disorders (OSTDs) would be related to GERD. The study aimed to investigate the association OSTDs and GERD.GERD patients (105 cases), older and younger controls (25 cases each) were retrospectively examined for oral symptoms, salivary flow volume (Saxon test), swallowing function (repetitive saliva swallowing test [RSST]), teeth (decayed, missing, and filled [DMF] indices), and soft tissues (as evaluation of OSTDs, gingivitis; papillary, marginal, and attached [PMA] gingival indexes, simplified oral hygiene indices [OHI-S], and inflammatory oral mucosal regions). Clinical histories, which included body mass index [BMI], the existence of alcohol and tobacco use, and bruxism, were also investigated. A P value of <0.05 was defined as statistically significant.GERD patients, older and younger controls participated and aged 66.4 ± 13.0, 68.3 ± 8.2 and 28.7 ± 2.6 years old, respectively. The most common oral symptom in the GERD patients was oral dryness. Salivary flow volume and swallowing function in the GERD patients were significantly lower than in either of the controls (all P < 0.05). Inflammatory oral mucosal regions were found only in the GERD patients. The DMF indices, as a measure of dental caries, in the GERD patients were higher than in the younger controls (P < 0.001), but lower than in the older controls (P = 0.033). The PMA gingival indexes, as a measurement for gingival inflammation, and OHI-S, as a measure for oral hygiene, in the GERD patients were significantly higher than in either of the controls (all P < 0.05). Though no significant differences in BMI, the existence of alcohol and tobacco use were found, bruxism, as an exacerbation factor of periodontal disease, in the GERD patients was significantly more frequent than in either control group (P = 0.041).OSTDs were associated with GERD, which was similar to the association between DE and GERD.

Project description:BackgroundNot all gastroesophageal reflux-induced cough (GERC) patients respond to anti-reflux treatment. It is not certain whether reflux-related symptoms or other clinical characteristics could indicate a successful response to anti-reflux treatment. In this study, we aimed to investigate the relationship between clinical features and anti-reflux response.MethodsWe retrospectively analyzed the clinical characteristics of suspected GERC who had reflux-related symptoms or reflux evidence based on abnormal 24-hour esophageal pH value monitoring, or who had no evidence of other common causes of chronic cough in our chronic cough database with a standard case report form. All patients experienced anti-reflux treatment with proton pump inhibitors (PPIs) plus prokinetic agents for at least 2 weeks and were divided into responders and non-responders based on the treatment response.ResultsAmong 241 patients with suspected GERC, 146 (60.6%) showed a successful response. There was no significant difference in regard to the proportion of reflux-related symptoms, and results of 24-hour esophageal pH value monitoring between responders and non-responders. Compared with non-responders, responders had higher proportions of nasal itching (21.2% vs. 8.4%; P=0.014), tickle in the throat (51.4% vs. 35.8%; P=0.025) and lower proportion of pharyngeal foreign body sensation (32.9% vs. 54.7%; P=0.001). Multivariate analysis showed that nasal itching [hazard ratio (HR): 1.593, 95% confidence interval (CI): 1.025-2.476, P=0.039], tickle in the throat (HR: 1.605, 95% CI: 1.152-2.238, P=0.005), pharyngeal foreign body sensation (HR: 0.499, 95% CI: 0.346-0.720, P<0.001) and sensitivity to at least one cough trigger (HR: 0.480, 95% CI: 0.237-0.973, P=0.042) were associated with the therapeutic response.ConclusionsOver half of suspected GERC patients benefited from anti-reflux therapy. A few clinical features rather than reflux-related symptoms might indicate a response to anti-reflux treatment. Further study is needed for the predictive value.

Project description:BackgroundEmpiric therapy with multichannel intraluminal impedance-pH monitoring (MII-pH) has been used for the initial treatment of gastroesophageal reflux-induced chronic cough (GERC). However, an algorithm based on the gastroesophageal reflux disease questionnaire (GerdQ) has the potential to achieve a simple, structured, and effective treatment approach for patients with GERC.ObjectivesThis study compared the efficacy of anti-reflux therapy based on GerdQ (new structured pathway, NSP) with medical treatment after MII-pH examination (ordinary clinical pathway, OCP) in the management of GERC.DesignFor the NSP, we adapted the GerdQ score to establish the basis for a treatment algorithm. For the OCP, treatment was determined using the MII-pH examination results.MethodsThe non-inferiority (NI) hypothesis was used to evaluate NSP versus OCP.ResultsOverall, the NSP and OCP-based therapeutic algorithms have similar efficacy for GERC [NI analysis: 95% confidence interval (CI), -4.97 to 17.73, p = 0.009; superiority analysis: p = 0.420]. Moreover, the cough symptom scores and cough threshold improved faster in the NSP group than in the OCP group at week 8 (p < 0.05). In the subgroup analyses using the GerdQ and GerdQ impact scale (GIS) scores, patients with low-likelihood GERC (GerdQ < 8) were more likely to benefit from OCP (NI analysis: 95% CI, -19.73 to 18.02, p = 0.213). On the other hand, in patients with high-likelihood and low-reflux impact GERC patients (GerdQ > 8 and GIS < 4), the NSP arm was not inferior to the standard treatment of OCP (NI analysis: 95% CI, -8.85 to 28.21%, p = 0.04; superiority analysis: p = 0.339), indicating that GerdQ- and GIS-guided diagnosis and management of patients with GERC could be an alternative to MII-pH management, especially in settings with reduced medical resources.ConclusionsThe use of the GerdQ algorithm should be considered when handling patients with GERC in the primary care setting.Trial registrationThis research was registered in the Chinese Clinical Trials Registry (ChiCTR-ODT-12001899).
