Management of GERD-Related Chronic Cough

Lesser-known symptoms of GERD

The reflux theory shows that outward indications of asthma are due to reflux of acid in to the esophagus accompanied by aspiration in to the proximal airways. The synergistic interactions between esophageal nociceptors and airway sensory nerves may precipitate asthma-like symptoms associated with GERD.[14] It has additionally been observed that abrupt decrease in tracheal pH coincides with broncho-constriction during episodes of gastroesophageal reflux in patients with asthma and typical GERD symptoms.[9] In children, the prevalence of GERD as an underlying cause of chronic cough is reported to be 4% to 15%.[12] By using stringent criteria, Blondeau et al.[13] found that acidic reflux was a potential mechanism of cough in 23% of patients; and weak acidic reflux contributed to cough in another 17% of the patients. Adding 24-hour esophageal pH testing in the diagnostic armamentarium, GERD can take into account chronic cough in around 40% of patients.

Role of Surgery in GERD

Six studies comparing PPI treatment (2 or 3 a few months) with placebo were included and analyzed on an intention-to-treat basis. If GERD symptoms can be found, commence a 3-month empiric twice-daily trial of PPI, while monitoring baseline respiratory symptoms, pulmonary symptoms and peak expiratory flow rate. Long-term medication therapy is normally essential to treat severe, persistent symptoms or complications of GERD.

Medicines along with other treatments

  • People that have an asthmatic (although not classic asthmatic) cough have an eosinophilic inflammation precipitated by the airway reflux.
  • Treating GERD without treating the abnormal reflex may not necessarily improve the cough; the abnormal reflex has to be treated aswell.
  • Asthmatic cough was described in patients without bronchoconstriction but who had hyper-reactivity to challenge with bronchoconstricting agents such as methacholine [8].
  • The most typical complication of fundoplication is swallowed food that sticks at the artificial sphincter.
  • They noted that subjects reported only 10% of manometrically determined coughs when esophageal pH and manometry were measured simultaneously.
  • We will need to determine the etiology of the neuropathy along with develop diagnostic and treatment algorithms for this.

Patients who failed to respond to empirical therapy should be investigated. The next strategy includes investigations, which should ideally detect both acidic and non-acidic reflux. Chang et al.[29] concluded within their meta-analysis (including only 11 trials) that usage of a PPI to take care of cough connected with GERD has some effect in a few adults. Overall, there was no significant difference between placebo and PPI (odds ratio = 0.46; 95% CI, 0.19-1.15) in the resolution of cough.

Gastric emptying studies are studies that determine how well food empties from the stomach. The foremost is in evaluating symptoms that not react to treatment for GERD since the abnormal function of the esophageal muscle sometimes causes symptoms that resemble the symptoms of GERD. For motility testing, a thin tube (catheter) is passed through a nostril, down the back of the throat, and into the esophagus. Esophageal motility testing determines how well the muscles of the esophagus are working.

Probably the most commonly recognized symptom of acid reflux disorder is “heartburn” because of irritation of the lining of the esophagus. Researchers used a cost-utility analysis to evaluate the cost-effectiveness of this diagnostic intervention among patients on high dose PPI therapy with chronic persistent cough who might be candidates for anti-reflux surgery, such as for example laparoscopic fundoplication. Researchers at the Medical University of South Carolina in Charleston studied a group of patients with persistent cough who took acid-suppression therapy (proton pump inhibitors) over a period of three years to judge the cost-effectiveness of MII-pH, a tool that may detect reflux without with respect to the acidity of the contents that refluxes in to the esophagus.

It is not clear, however, how effective chewing gum is in treating heartburn. One novel approach to the treating GERD is nicotine gum. Examples are spicy or acid-containing foods, like citrus juices, carbonated beverages, and tomato juice.

Furthermore, some investigators have discovered that cough can result in reflux, which in turn results in a cycle of cough (the cough-reflux-cough cycle). you have other symptoms, like food getting stuck in your throat, frequently being sick or losing weight for no reason a hiatus hernia – when section of your stomach moves up into your chest an unpleasant sour taste in the mouth area, due to stomach acid Combined multichannel intraluminal impedance and pH-metry: an evolving strategy to measure type and proximal extent of gastroesophageal reflux.

Blocking the efferent limb of the cough reflex with inhaled ipratropium (an anticholinergic agent) also inhibited cough, but esophageal ipratropium didn’t inhibit the cough reflex. Establishing a prevalence rate for GER-related cough is complicated by the truth that in many patients, cough can have multiple underlying cause. Also, during the past 25 years researchers have elucidated physiologic mechanisms explaining how GER causes cough. The esophagus and the lung share common embryonic foregut origins and vagal innervation. Cough resolution often occurs within 2 weeks of proton pump inhibitor therapy, but it may take a lot more than 50 days in a few patients.
