Pollinosis studies at Mexico City have found a considerable amount of Casuarina equisetifolia and Pinus spp pollen, its sensitization frequency is unknown. In Mexico, some allergens are not considered related to asthma or allergic rhinitis, even though reports in other countries have been demonstrated their relevance as aeroallergens.
To estimate the frequency of sensitization to Casuarina equisetifolia and Pinus spp pollen.
A transversal, descriptive trial was done at Hospital General de Mexico. Previous informed consent 142 patients with allergic rhinitis and asthma, 3 to 55 years old, were included to the study. A complete clinical evaluation, laboratory tests and skin prick tests were performed.
We included 142 patients, 44 children (64% males) and 98 adults (73% females). We found that 8 (18.18%) children and 35 (35.7%) adults had a positive skin prick test to Casuarina equisetifolia. None of the patients included in the study had a positive skin prick test to Pinus spp.
Sensitization to Casuarina equisetifolia is as important as other pollens found in Mexico City. These results suggest that it should be included when skin prick tests are performed. Pinus spp pollen is considered an aeroallergen in European countries but we did not corroborate sensitization in our population.
墨西哥城的花粉症研究发现了大量的木麻黄和松树花粉，但其致敏频率尚不清楚。在墨西哥，一些过敏原不被认为与哮喘或过敏性鼻炎有关，尽管其他国家的报告已证明它们作为气传过敏原的相关性。
评估对木麻黄和松树花粉的致敏频率。
在墨西哥总医院进行了一项横断面描述性试验。在获得先前的知情同意后，纳入了142例年龄在3至55岁之间的过敏性鼻炎和哮喘患者进行研究。进行了全面的临床评估、实验室检查和皮肤点刺试验。
我们纳入了142例患者，其中44例儿童（64%为男性）和98例成人（73%为女性）。我们发现8例（18.18%）儿童和35例（35.7%）成人对木麻黄的皮肤点刺试验呈阳性。研究中的患者对松树花粉的皮肤点刺试验均为阴性。
对木麻黄的致敏与在墨西哥城发现的其他花粉同样重要。这些结果表明，在进行皮肤点刺试验时应将其纳入。松树花粉在欧洲国家被认为是一种气传过敏原，但我们在研究人群中未证实其致敏情况。
