Eosinophilic Esophagitis in Cystic Fibrosis: A Case Series and Review of the Literature
Abstract
Patients with cystic fibrosis (CF) frequently experience gastrointestinal symptoms including nausea, emesis, malnutrition and indigestion; diseases such as gastroesophageal reflux disease (GERD), distal intestinal obstructive syndrome, and cholelithiasis are commonly implicated. We have recently diagnosed eosinophilic esophagitis (EoE) in three patients with CF. EoE is a TH-2 driven, allergen-mediated disease which causes esophageal eosinophilia and presents with symptoms of nausea, feeding intolerance, regurgitation, and dysphagia. EoE is diagnosed when esophageal biopsies reveal greater than 15 eosinophils per high power field in the setting of the appropriate clinical scenario and after exclusion of other causes of esophageal eosinophilia. Although described with increasing frequently in the gastrointestinal literature, there have been no prior cases documenting the co-existence of EoE and CF. We speculate that this is related to lack of familiarity with EoE symptoms by CF providers. We present three patients with CF diagnosed with EoE and review the current literature regarding diagnosis and management, focusing on management issues in patients with CF.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
