Unique Clinical Features of Los Angeles Grade D Esophagitis Suggest That Factors Other Than Gastroesophageal Reflux Contribute to its Pathogenesis.

ABSTRACT:

Background

The Los Angeles (LA) grade of reflux esophagitis (A to D) is assumed to reflect severity of the underlying gastroesophageal reflux disease (GERD). Thus, LA-D esophagitis patients might be expected to have the most conditions predisposing to GERD (eg, obesity, hiatal hernia), and the highest frequency of GERD symptoms.

Goals

The main goal of this study is to compare clinical features of patients with the most severe (LA-D) and mildest (LA-A) grades of esophagitis.

Study

For this comparative study, we searched our endoscopy database for patients diagnosed with LA-D or LA-A esophagitis, reviewed their endoscopic images, and reviewed medical records of the first 100 we confirmed to have LA-D or LA-A esophagitis.

Results

Compared with LA-A patients, LA-D patients were older (mean age, 65±13.4 vs. 56±13.4 y; P<0.001), had lower body mass index (25.9±5.6 vs. 29.4±5.3; P<0.001), were more frequently hospitalized (70% vs. 3%; P<0.001), and in the intensive care unit (15% vs. 0%; P<0.001), and had significantly more serious cardiopulmonary disorders and gastrointestinal bleeding. Conversely, a GERD history was more common in LA-A than LA-D patients (67% vs. 45%; P=0.002). Hiatal hernia was more frequent in LA-A patients than LA-D patients, but not significantly (48% vs. 36%; P=0.09).

Conclusions

LA-D esophagitis primarily affects hospitalized, older, nonobese patients who often have serious comorbidities, and no history of GERD or hiatal hernia. In contrast, LA-A patients are generally younger, obese outpatients who often have a history of GERD and hiatal hernia without serious comorbidities. These profound differences between LA-A and LA-D patients suggest that factors other than typical GERD contribute to LA-D esophagitis pathogenesis.

Project description:Background and objectiveGastroesophageal reflux disease (GERD)-associated cough is defined as a special GERD with a predominant cough symptom and is a common cause of chronic cough. This review summarizes our current understanding on the pathogenesis and management of GERD-associated cough.MethodsMain literatures on the pathogenesis and management of GERD-associated cough were reviewed and our understandings derived from the published studies were showed then.Key content and findingsAlthough esophageal-tracheobronchial reflex mainly underlies the pathogenesis of GERD-associated cough, its counterpart-tracheobronchial-esophageal reflex might exist and initiate the cough due to reflux induced by upper respiratory tract infection through the signaling of transient receptor potential vanilloid 1 linking airway and esophagus. The presence of reflux-associated symptoms such as regurgitation and heartburn along with coughing suggests an association between cough and GERD, which is supported by the objective evidence of abnormal reflux as detected by reflux monitoring. Although there is no general consensus, esophageal reflux monitoring provides the main diagnostic criteria for GERD-associated cough. Despite that acid exposure time and symptom associated probability are useful and mostly employed reflux diagnostic criteria, they are imperfect and far from being the gold standard. Acid suppressive therapy has long been recommended as the first choice for GERD-associated cough. However, the overall benefits of proton pump inhibitors have been controversial and need to be further assessed, especially in patients with cough due to non-acid reflux. Neuromodulators have demonstrated potential therapeutic effects for refractory GERD-associated cough, for which anti-reflux surgery may also be a promising treatment option.ConclusionsTracheobronchial-esophageal reflex might initiate reflux-induced cough provoked by the upper respiratory tract infection. It is necessary to optimize the current standards and to explore new criteria with higher diagnostic potency. Acid suppressive therapy is the first choice for GERD-associated cough, followed by neuromodulators and anti-reflux surgery for refractory GERD-associated cough.
