How to Tell the Difference Between Eosinophilic Esophagitis and GERD

March 21, 2023

Chest pain, difficulty swallowing, and heartburn may be symptoms of gastroesophageal reflux disease (GERD), or eosinophilic esophagitis (EoE)? Both conditions have overlapping symptoms making it difficult to distinguish one from another.

 

Let us explore the differences between eosinophilic esophagitis and GERD by looking at their causes, diagnosis, treatment, and response to medications.

Causes

Eosinophilic esophagitis is a chronic immune system disease where the white blood cells, called eosinophils, build up in your esophagus. Increased numbers of eosinophils are present in the esophagus and may be related to foods, allergens or acid reflux. This causes inflammation which leads to the symptoms noted above.

 

GERD occurs when acid from the stomach flows back into the esophagus repeatedly. This is called acid reflux and can irritate the esophagus lining. It happens when the lower esophageal sphincter (valve) becomes weak and cannot close tight immediately after food enters the stomach, causing the food to go back into the esophagus.


Diagnosis

Upper endoscopy and biopsy are used to diagnose eosinophilic esophagitis. Endoscopy aids in the detection of esophageal inflammation, but biopsy is required to diagnose eosinophilic esophagitis.

 

GERD diagnosis starts with the patient history which may be suggestive of the diagnosis and lead to initiation of therapy. In some cases, you may have to perform tests like an upper endoscopy and biopsy, X-ray of the upper gastrointestinal tract, or esophageal manometry, which test the functionality of the lower esophageal sphincter.


Treatment

In eosinophilic treatment aimed at reducing the inflammatory response. Inhaled corticosteroids sprayed into the oral cavity and swallowed or oral corticosteroid suspensions can be used to treat eosinophilic esophagitis. Monoclonal antibody medications, such as dupilumab, are also effective in treating this condition.

 

Managing eosinophilic esophagitis may call for dietary restrictions. Foods like milk, eggs, nuts, beef, wheat, fish, shellfish, corn, and soy may be targeted first.

 

The most common medications for GERD include the following:

●    Antacids that neutralize the acids in the stomach.

●    H-2 receptor blockers to inhibit acid production.

●    Proton pump inhibitors are used when a more potent medication is needed to reduce acid production. It also helps the esophagus tissue heal.


Response to Medication

Patients with EoE and GERD may both respond to proton pump inhibitors.  As eosinophilic esophagitis occurs as a response to food or environmental allergens, acid-suppressive therapies do not always improve symptoms.

 

When antisecretory medication is ineffective, especially in young men with atopic disease or with any red flags (i.e., weight loss, dysphagia, or food bolus impaction history), an endoscopic examination should be conducted immediately to determine whether there is eosinophilic esophagitis.

 

Distinguishing eosinophilic esophagitis from GERD can be challenging and medical professionals must be completely aware of the differences in presentation, diagnosis and treatment. Discussion and collaboration with others in similar fields can give practical and insightful information, and Snot Force Alliance is just the right place.

Inflammatory airway diseases can impact a patient's quality of life. Untreated conditions leave patients struggling to breathe, coughing regularly, and feeling unwell for months at a time. Airway disease management has undergone significant changes in recent years. Treating airway diseases has become increasingly complex, despite improvements in methodologies and technologies. In rural and underserved regions, many patients lack access to specialty care. Key Takeaways: Providing high-quality care to patients with airway disease requires collaboration across specialties. It is important to expand rural ENT access and access to multidisciplinary clinics. Clinicians in rural communities can improve patient outcomes through collaborations and with creative solutions that expand airway care. The Need for Multidisciplinary Airway Care Airway diseases affect multiple systems of the body and thus are treated by different types of physicians. Allergists, primary care doctors, pulmonologists, and ENT physicians all play a role in caring for patients with airway conditions. Physicians who can facilitate multidisciplinary care can improve diagnostic accuracy while also helping to ensure better patient outcomes. Challenges in Rural and Underserved Communities Rural ENT access is spotty at best. Many rural areas lack specialty physicians and often, patients must travel long distances to tertiary medical centers where they receive care. As a result, patients with limited transportation options may experience delays in diagnosis and care. Sometimes, these specialty care disparities can leave primary care providers to manage complex airway conditions on their own. In areas where insurance coverage is limited, and referral networks are fragmented, patients may struggle with their conditions without treatment at all. The Consequences of These Limitations Delays in diagnosis and treatment mean poor management of chronic conditions and increased reliance on treatment from acute care settings. Under this system, patients become frustrated as they lean on ineffective treatment methods. Methods for Expanding Access There are many methods for expanding access to patients in rural and underserved areas. Telehealth Airway Care The use of telehealth treatment has significantly expanded in recent years. With telehealth tools, hybrid care models combine in-person and virtual visits. This same technology also connects doctors, bringing together specialists and community clinicians. Regional Centers of Excellence Multidisciplinary airway centers have proven effective for helping patients access specialty care. Airway centers make it easier to streamline referrals in complex cases. These airway centers can serve larger geographic areas by setting up outreach clinics in surrounding communities. Collaborative Networks Partnerships and collaborations between physicians are key to ensuring that primary care providers in underserved areas have access to resources and information. Supporting Rural Physicians There are many ways to support rural physicians. Snot Force has committed to build networks for physicians, helping to ensure the dissemination of information across specialties and practice settings. We facilitate collaboration between disciplines to promote innovation in care for underserved communities. We're bringing doctors together to break down specialty care disparities and improve rural ENT access and information. Our research collaborative depends on many medical professionals to participate, and we're always looking for more physicians to join the force. To learn more, contact Snot Force today .
