Background & Aims:
Eosinophilic esophagitis (EE) occurs in families.
Methods:
Record review confirmed patient kinship and provided clinical information. Slide review confirmed the diagnosis (threshold peak number > or = 24 eosinophils/high-power field).
Results:
Fifty-nine members (41 males, 18 females) of 26 families were 3 months to 47 years of age (mean age, 10.3 y) at diagnosis. The only recorded race was Caucasian. In 4 families a parent of an affected male had EE. The most common complaint at diagnosis was dysphagia (68% of patients). Endoscopy showed esophageal mucosal furrows (93% of patients) and exudates (44%). Fifty-one percent had asthma. Skin prick tests to food and aeroallergens were positive in 76% and 71%, respectively. Familial EE characteristics (clinical, endoscopic, pathologic, and global esophageal transcript expression profile analysis) were similar to sporadic EE, except among patients with mucosal furrows: familial patients had lower peak eosinophil counts in the distal esophagus (P = .03) compared with sporadic patients. The basic characteristics of EE (eg, eosinophil levels, rate of atopy) did not vary with patient age. By using genome-wide microarray analysis, no significant differences (P < .05, false-discovery rate) were observed between familial and sporadic EE. Among all patients, chest pain was more common in females (P = .02), and thickened mucosa was more common in males (P = .006).
Conclusions:
These data support a familial pattern of inheritance of EE and a pathogenesis shared with sporadic EE. EE should be considered in symptomatic family members of patients who have EE.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
