Heterogeneous Predisposing Factors and Etiology of Edema of the Uvula in a Spanish Population.
Edema of the uvula (EU) may appear in isolation or in association with clinical manifestations such as urticaria, angioedema, and anaphylaxis. EU may lead to upper airway obstruction, provoking obstructive respiratory distress and asphyxia. Objective: We sought to investigate the etiology of and predisposing factors for EU in a large population of patients referred to an outpatient clinic. ⋯ Isolated EU was associated with snoring, an elongated uvula, and having experienced previous episodes of EU. We found no associations between groups of EU patients and gender, obesity, smoking, alcohol consumption, personal and family history of atopy, and obstructive sleep apnea. Allergy to A simplex was the most commonly recorded cause.

IgE-Mediated Sensitization to Galactose-α-1,3- Galactose (α-Gal) in Urticaria and Anaphylaxis in Spain: Geographical Variations and Risk Factors.
The objectives of this study were to investigate the prevalence of sIgE to galactose-α-1,3-galactose (α-gal) in individuals with acute urticaria or anaphylaxis from different geographical areas of Spain and to evaluate the relevance of demographics and lifestyle as risk factors for this immune response. ⋯ Sensitization to α-gal in patients with urticaria or anaphylaxis differs considerably between the 3 geographical areas studied and is related to tick bites.
