The measurement of polycyclic aromatic hydrocarbons (PAH) in ambient air is quite difficult to perform. Using urine biomarkers of PAH such as 2-naphthol is one approach to this problem. This study explored the association between urine 2-naphthol levels and allergic diseases. The associations between 2-naphthol levels and oxidative stress biomarkers for the possible disease pathogenesis were also investigated.
A total of 453 kindergarten children from the (Childhood Environment and Allergic Diseases Study) CEAS cohort with urine samples were recruited. Urine 2-naphthol levels were measured by high-performance liquid chromatography mass spectrometry (HPLC-MS/MS) and markers of oxidative stress (8OHdG) were measured by enzyme-linked immunosorbent assays (ELISA). Information on environmental risk factors and allergic diseases were also collected. The association between 2-naphthol levels, 8OHdG levels, IgE, and allergic diseases were evaluated by multivariate linear regression and logistic regression.
Levels of 2-naphthol were positively correlated with 8OHdG levels. A one ln-unit increase in the 2-naphthol level was positively associated to 8OHdG levels (per ln-unit: β = 100.61, p < 0.001). When dividing 2-naphthol levels into quartiles, asthma was significantly associated with 2-naphthol levels at a concentration of >1.60 ng/mL (adjusted OR: 3.14, 95% CI 1.34⁻7.35).
Urine 2-naphthol levels are associated with markers of oxidative stress and the risk of allergic diseases in young children.
环境空气中多环芳烃（PAH）的测量相当困难。使用尿液中 PAH 的生物标志物，如 2-萘酚，是解决此问题的一种方法。本研究探讨了尿液 2-萘酚水平与过敏性疾病之间的关系。还研究了 2-萘酚水平与氧化应激生物标志物之间的关联，以探讨可能的疾病发病机制。
共招募了来自（儿童环境与过敏性疾病研究）CEAS 队列的 453 名幼儿园儿童，他们有尿液样本。采用高效液相色谱-质谱联用（HPLC-MS/MS）法测定尿液 2-萘酚水平，采用酶联免疫吸附试验（ELISA）法测定氧化应激标志物（8OHdG）。还收集了环境危险因素和过敏性疾病的信息。采用多元线性回归和逻辑回归评估 2-萘酚水平、8OHdG 水平、IgE 与过敏性疾病之间的关系。
2-萘酚水平与 8OHdG 水平呈正相关。2-萘酚水平每增加一个 ln 单位与 8OHdG 水平呈正相关（每 ln 单位：β=100.61，p<0.001）。当将 2-萘酚水平分为四等分时，哮喘与浓度>1.60ng/mL 的 2-萘酚水平显著相关（调整后的 OR：3.14，95%CI 1.34⁻7.35）。
尿液 2-萘酚水平与氧化应激标志物和幼儿过敏性疾病的风险相关。
