Olea europaea (olive) which is original from Europe, was introduced to Mexico by the Spaniards in the 16th century. In 1777 olive farming was prohibited, and plantations were destroyed. At present there are only few trees in Southern Mexico City. The aim of this study is to investigate sensitization to Olea europaea, clinical features, IgE levels, and concurrent pollen sensitizations in a group of Mexican patients.
A retrospective chart review of all patients (n=232) with pollen allergy, between August 2003 and August 2004, in a medical office.
The sensitization to Olea europaea was found in 41.5% (96). The median IgE levels was 387.2 UI/ml. Symptoms were: 95.8% with allergic rhinitis, 58.3% asthma, 66.6% chronic sinusitis, 36.4% otitis media with effusion, 29.1% allergic conjunctivitis, 16.6% atopic dermatitis, 16.6% oral allergy syndrome, mainly related to apple and strawberries; and 4.5% paranasal polyposis. Positive skin prick tests to Olea europaea were higher on April (27.2%), and lower on November (2.5%).
Olea europaea is an important sensitizer in Mexico City. Cross-reaction to other pollens belonging to Oleaceae family, possibly Osmanthus americanus, could explain monosensitization to olive tree.
油橄榄原产于欧洲，16世纪由西班牙人引入墨西哥。1777年，油橄榄种植被禁止，种植园被摧毁。目前，墨西哥城南部仅有少数油橄榄树。本研究旨在调查一组墨西哥患者对油橄榄的致敏情况、临床特征、免疫球蛋白E（IgE）水平以及并发的花粉致敏情况。
对2003年8月至2004年8月间一家医疗机构中所有花粉过敏患者（n = 232）的病历进行回顾性分析。
发现41.5%（96例）患者对油橄榄致敏。IgE水平中位数为387.2国际单位/毫升。症状包括：95.8%患有过敏性鼻炎，58.3%患有哮喘，66.6%患有慢性鼻窦炎，36.4%患有分泌性中耳炎，29.1%患有过敏性结膜炎，16.6%患有特应性皮炎，16.6%患有口腔过敏综合征，主要与苹果和草莓有关；4.5%患有鼻息肉。对油橄榄的皮肤点刺试验阳性率在4月较高（27.2%），11月较低（2.5%）。
在墨西哥城，油橄榄是一种重要的致敏原。对木犀科其他花粉（可能是美洲桂花）的交叉反应可能解释了对油橄榄树的单一致敏情况。
