BACKGROUND
The bite of Triatominae can cause cutaneous allergic reactions and even anaphylaxis. Since the early 1980s, no population-based surveys have been done in Southern California, and none was ever carried out in inland Los Angeles or Riverside Counties.
OBJECTIVES
To measure the frequency of insect sightings, bites and allergic reactions in a suburban area of eastern Los Angeles County and along with rural and urban sites in Riverside County.
METHODS
A door-to-door survey was done in triatomine exposed and unexposed areas. Logistic regression modeling was used for the analysis, and study participants were asked to collect insects.
RESULTS
Out of the 221 study participants in the exposed areas, 46 (20%) knew about the presence of Triatominae in their neighborhood. Fifteen (7%) persons reported triatomine sightings in their house during the month preceding the interview. Also, 15 (7%) participants reported ever being bitten by a triatomine. Ten (5%) participants collected either a Triatoma protracta Uhler and/or Paratriatoma hirsuta Barber in and around their house. Twenty-nine (13%) persons in the rural Riverside County reported symptoms compatible with allergy to triatomine bites. This was 4 times higher than in the urban control area where only 4 (3%) of 115 persons reported these symptoms. The association between living in a triatomine-exposed area and self-reported symptoms suggestive of allergies increased slightly when adjusted for the participant's sex and the age of their house (adjusted odds ratio: 5.1, 95% confidence interval: 1.2 to 22.0). Reporting these symptoms was associated with seeing Triatominae in the neighborhood and having been bitten.
CONCLUSION
Allergies to triatomine bites could be a significant problem in inland Southern California. Further investigations, a diagnostic test and better information of persons living in triatomine-exposed areas are needed.
背景
克氏锥虫叮咬会引起皮肤过敏反应，甚至过敏反应。自 20 世纪 80 年代初以来，南加州尚未进行过基于人群的调查，内陆的洛杉矶县或里弗赛德县也从未进行过此类调查。
目的
测量洛杉矶县东部郊区以及里弗赛德县农村和城市地区的昆虫目击、叮咬和过敏反应的频率。
方法
在暴露和未暴露于锥虫的地区进行了逐户调查。使用逻辑回归模型进行分析，并要求研究参与者收集昆虫。
结果
在暴露于锥虫的 221 名研究参与者中，有 46 人（20%）知道他们附近有锥虫的存在。在接受采访前一个月，有 15 人（7%）报告在自己家中看到过锥虫。此外，有 15 名（7%）参与者报告曾被锥虫叮咬过。有 10 人（5%）在他们的房屋周围收集到了 Triatoma protracta Uhler 和/或 Paratriatoma hirsuta Barber。在农村的里弗赛德县，有 29 人（13%）报告出现与对锥虫叮咬过敏相符的症状。这一比例是城市对照区的 4 倍，在该对照区，仅有 115 人中有 4 人（3%）报告了这些症状。当调整参与者的性别和房屋年龄后，居住在锥虫暴露区与自述过敏症状之间的关联略有增加（调整后的优势比：5.1，95%置信区间：1.2 至 22.0）。报告这些症状与在社区中看到锥虫和被叮咬有关。
结论
对锥虫叮咬的过敏反应可能是南加州内陆地区的一个严重问题。需要进一步调查、诊断测试和更好地了解居住在锥虫暴露地区的人群。
