Abstract
Background:Eosinophilic gastroenteropathy is an uncommon condition whose causes can be numerous and non-specific. The aim of the study was to characterize the presence of gastrointestinal disorders in the adult Maltese population and assess the degree of association with atopic diseases.Methods:Adult patients with gastrointestinal eosinophilia in the gastrointestinal tract on histology were identified and their clinical case notes were reviewed. Patients were interviewed and asked questions regarding asthma, allergic rhinitis, and eczema.Results:Sixty-six patients (39 female) were recruited. The most common clinical symptoms were diarrhea (42.4%) and abdominal pain (33.3%). The sites involved were stomach (10.6%), colon (56.1%), small bowel (10.6%), small bowel and colon (18.2%), esophagus (1.5%), and esophagus and colon (1.5%). Forty percent had persistent lower gastrointestinal symptoms and a repeat ileocolonoscopy was performed within 12 months. These patients were diagnosed with ulcerative colitis (n=10; 47.6%), Crohn’s disease (n=6; 28.6%), indeterminate colitis (n=1; 4.8%) or microscopic colitis (n=4; 19%). Allergic rhinitis was present in 39.4% of the study group, eczema in 26.1%, and asthma in 19.7%. These findings were compared with local data for atopic conditions and the study group was found to have a significantly higher prevalence of allergic rhinitis (P=0.002), but not of asthma (P=0.62) or eczema (P=0.19).Conclusions:A high proportion of patients with eosinophilic gastrointestinal infiltration were subsequently diagnosed with inflammatory bowel disease. Patients persistently symptomatic or who do not respond to treatment should be reassessed to exclude inflammatory bowel disease, given its high prevalence in this group of patients.
