Esophagitis

Esophagitis is the inflammation of the mucosal lining of the esophagus, the muscular tube carrying food from the pharynx to the stomach. It arises from diverse etiologies including acid reflux, infections, drug irritations, or allergic hypersensitivity, leading to painful or difficult swallowing and tissue damage.

• Gastroesophageal Reflux (GERD): Chronic exposure to acidic gastric contents.

• Chemical/Pill Irritation: Direct mucosal contact with medications (e.g., NSAIDs, tetracyclines, bisphosphonates, potassium chloride).
• Allergic/Atopic Response: Food or environmental allergens triggering Eosinophilic Esophagitis (EoE).
• Radiation Therapy: Collateral damage to esophageal tissue during thoracic oncology treatments.

The esophageal mucosa relies on a tight squamous epithelial barrier and peristalsis to clear noxious agents. When defensive barriers fail:

1. Reflux Esophagitis: Hydrogen ions penetrate the intercellular junctions of the squamous epithelium, causing chemical burns, cell swelling, and desquamation.


2. Eosinophilic Esophagitis: An antigen-driven, Th2-mediated immune response recruits eosinophils, leading to tissue remodeling, rings, and strictures.


3. Infectious Esophagitis: Microorganisms invade the compromised mucosa, forming plaques (Candida) or discrete ulcers (punched-out in HSV; shallow, large in CMV).

• Reflux Esophagitis: Affects 10–20% of adults in Western countries; correlates with rising obesity rates.
• Eosinophilic Esophagitis: Predominantly affects young males (3:1 male-to-female ratio) with history of atopic diseases.
• Infectious Esophagitis: Common in patients with HIV/AIDS (CD4 count < 200 cells/µL), transplant recipients, or those on systemic immunosuppression.

• Hiatal hernia and obesity
• Immunosuppression (HIV, chemotherapy)
• Atopic diseases (asthma, eczema, food allergies)
• Tobacco and alcohol consumption
• Lying down immediately after oral medication intake

Physical findings are often minimal or absent unless secondary to underlying systemic diseases:

• Vitals: Fever may be present in acute infectious esophagitis.


• Oropharyngeal Inspection: Oral thrush (suggestive of Candida esophagitis) or herpetic vesicles.


• Abdominal Palpation: Epigastric tenderness upon deep palpation.

• A. Clinical Assessment: Symptom evaluation and medication history review.
• B. Laboratory Testing: Indicated to rule out systemic infection or immunodeficiency.
• C. Imaging Studies: Useful to screen for structural abnormalities.
• D. Functional Tests: Esophageal manometry assesses peristaltic function.
• E. Biopsy Findings: Gold standard obtained via Esophagogastroduodenoscopy (EGD). Eosinophilic esophagitis requires $\ge 15$ eosinophils per high-power field (hpf).
• F. Genetic Testing: Not routinely indicated.
• G. Differential Diagnosis: Differentiating from cardiac ischemia, achalasia, or diffuse esophageal spasms.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: Screen for systemic infection, eosinophilia, or anemia from chronic bleeding.
Expected Findings: Elevated white blood cells (infection), elevated eosinophils (allergic/EoE), low hemoglobin (chronic bleeding).
Interpretation: Eosinophilia points toward EoE; leukocytosis points to infection.

Barium Swallow (Esophagram): Purpose: Evaluate structural changes. Typical Findings: Mucosal irregularity, strictures, hiatal hernia, or "crenellated" rings (suggestive of EoE). Clinical Importance: Safely identifies mechanical obstructions prior to endoscopy.

• Myocardial Infarction: Differentiated by abnormal ECG, elevated troponins, and absence of dysphagia.
• Achalasia: Characterized by "bird's beak" appearance on barium swallow and lack of peristalsis on manometry.
• Esophageal Spasm: Presents with severe, intermittent pain and "corkscrew" appearance on barium swallow.

• Esophageal Strictures: Narrowing from chronic scarring.
• Barrett's Esophagus: Intestinal metaplasia of the squamous epithelium, predisposed to adenocarcinoma.
• Esophageal Perforation: Rupture of the esophageal wall (medical emergency).

• Short-term: High resolution rates with targeted therapy (e.g., PPIs or antifungals).
• Long-term: Chronic conditions like EoE or severe GERD require maintenance therapy to prevent recurrences and remodeling.

Avoid esophageal irritants, maintain a healthy body weight, and take oral pills with adequate water.
