Eosinophilic Pancreatitis Diagnosis and Treatment

Introduction to Eosinophilic Disorders

• Basophilia often accompanies eosinophilia in conditions such as allergic disorders, as both cell types are involved in type 2 immune responses 1

Diagnostic Considerations

• Endoscopic evaluation with biopsy is essential for diagnosis, looking for eosinophilic infiltration (≥15 eosinophils per high-power field) in the gastrointestinal tract, particularly the stomach and duodenum 2, 3
• Other autoimmune disorders affecting the pancreas should be ruled out 2

Treatment Approach

• Systemic corticosteroids are the first-line treatment for eosinophilic pancreatitis, with prednisone 1-2 mg/kg/day (maximum 60 mg) recommended for severe cases 4
• Clinical symptoms typically improve within 7 days of starting corticosteroid therapy, with histological improvement within 4 weeks 4
• The duration of treatment should be at least 8-12 weeks before evaluating the histological response 4, 5

Dietary Management

• Dietary elimination therapy should be considered when food allergies are identified as triggers 4, 5
• A dietitian's support is crucial during the process of elimination and reintroduction of foods 5

Treatment for Refractory Cases

• For patients with refractory disease, joint management by a gastroenterologist and an allergist specialist is recommended 4, 5
• Novel biologics used in other allergic conditions have shown promising results in eosinophilic disorders 5

Monitoring and Follow-up

• Endoscopy with biopsy is recommended while the patient is on treatment to evaluate the histological response, as symptoms do not always correlate with histological activity 4, 5
• Patients should be monitored for potential complications of corticosteroid therapy, including Candida infections, which should be managed with topical antifungals while continuing steroids 4
