COPD Patients With Acid Reflux

Research shows that COPD patients are at a greater risk of developing GERD than those without the lung disease. More than half of those with advanced COPD also have GERD. If you have COPD or another breathing disease, it’s important to catch it early and treat it as soon as possible. If you get early treatment for COPD, you can slow down the damage to your lungs.

Further investigation is needed to more definitively clarify the role of GER treatment in the care of IPF. The results of studies evaluating anti-reflux surgical interventions for IPF will inform our understanding of the pathogenic function of duodenogastric reflux, where surgery is a more definitive therapy for bile acid reflux.

The cause of epithelial injury remains unknown, but cigarette smoking, chronic viral infections, exposure to wood and dust particles, and drug toxicity have been associated with IPF [3 ]. In addition to these exposures, recent studies have revealed the potential role of gastroesphageal reflux (GER) and microaspiration as a possible cause of recurrent epithelial injury [4 ]. GER includes reflux of both acidic and non-acidic content, symptomatic disease, and asymptomatic events. However, although a high incidence of acid aspiration in IPF has been detected in several series, the role of GER in either the cause or the progression of IPF is not well understood [5 •], and the association of GER and IPF is a topic of intense ongoing investigation.

We also demonstrated that the sputum inflammatory indices under stable conditions were similar between patients with GORD symptoms and those without (see table 6S online). Considering these findings, we speculated that GOR might occur frequently even under stable conditions that cause the EBC pH to fall without aggravating airway inflammation, whereas gastric dysmotility might predispose an individual to episodic aspiration of low acidic gastric contents and induce exacerbations. Moreover, impaired gastric motility might disturb the clearance of swallowed contents from the pharynx to the oesophagus, leading to their aspiration into the tracheobronchial tree and thereby causing exacerbations.

We suppose that a smaller lowering of the diaphragm in patients with COPD keeps the diameters of the crura and of the esophagus wider, favoring the presence of GERD. Nonetheless, the authors recommended that these extrapulmonary causes of cough and sputum should be explored when assessing symptoms of bronchitis in patients with COPD. 99 Tc scintigraphy with lung scanning to show that microaspiration of gastric contents occurred even if pathological GOR was not detected with 24 h intraoesophageal pH monitoring.35 Moreover, to determine whether the EBC pH reflected GOR, and whether GOR or gastric dysmotility was more strongly associated with the frequency of exacerbations, we investigated the associations among the frequency of exacerbations, EBC pH and the symptom subtypes of the FSSG associated with GOR and gastric dysmotility. The number of exacerbations was significantly correlated with those associated with gastric dysmotility but not with GOR (see fig 1S online), whereas the EBC pH was inversely correlated with those associated with GOR but not with gastric dysmotility (see fig 2S online).

People who recognize the first symptoms, which may include blood in the mucus, excessive mucus, and shortness of breath, should see a doctor. Learn more about the early symptoms of COPD here.

Cost consequences of GERD in COPD

has proved a useful biomarker for aspiration in lung transplant recipients [45 ]. It has been previously hypothesized that acute exacerbations of IPF may be caused by microaspiration [46 ]. Pepsin levels in BAL fluid from patients experiencing exacerbations of IPF were significantly elevated compared to levels of control patients with stable disease [47 •]. It remains to be determined whether pepsin levels differ, and if so by how much, for stable patients with IPF or patients in the early stages of disease compared with healthy controls. In scleroderma, the relationship between esophageal dysfunction and ILD has been a topic of active investigation, but remains unknown.

Asymptomatic aspiration of oropharyngeal secretion or gastric fluid into the lungs is called silent microaspiration. It has been demonstrated that approximately half of normal adults experience mild silent microaspiration during sleep at night [19 ]. Normally, natural defenses, including coughing and epiglottic closure, are protective against microaspiration. Depending on the individual, sometimes these defenses become impaired and cause wheezing and coughing [20 ]. Heartburn and gastroesophageal reflux disease (GERD).

Larger randomized trials of surgical intervention for IPF patients with reflux will be informative, and are in progress (UO1 UCSF Collard is lead PI). While GERD and LPR are both related to excess stomach acid in the throat, a person can have one problem or the other, or both simultaneously. Treatment for chronic cough starts with identifying the cause, and managing symptoms through medication and lifestyle or behavioral changes. If these problems have been ruled out, you may have sensorineuropathic cough, which results from abnormal throat and voice box sensations from malfunctioning nerves. Symptoms include chronic cough and chronic throat clearing and can affect the voice.

We suppose that LBP in patients with COPD is also caused by the fascial system, despite not having any data that can substantiate this statement. It’s also important to understand that if you have both GERD and COPD, your flare ups of your COPD are likely to occur more often and be more severe.

Even the most hardened opponent of the reflux hypothesis will acknowledge that a proportion of patients with chronic cough suffer from reflux disease. Indeed, it would be hard to argue that a patient with a full house of reflux symptoms, both peptic and non-acid related, who is subsequently shown to have an anatomical abnormality of the oesophago-gastric junction such as a hiatus hernia and is then cured by fundoplication, does not clearly demonstrate the validity of the concept. It is thus simply a question of how much one believes that reflux is atypical rather than peptic in origin. The additional problem with other respiratory disease is that, unlike cough, there are established diagnostic criteria built up over many years, often soundly based on clinical and biomarker studies. A large body of the respiratory scientific community depends for their living on these diseases having specific criteria exclusive to their specialism and expertise.
