The neurotoxic effects of lead in children can have long-lasting and profound impacts on the developing nervous system. This study aimed to identify a reliable and easily accessible biomarker to monitor neurological impairment in lead-poisoned children.
We analyzed hematological data from 356 lead-poisoned children, comparing them with age and gender-matched healthy controls. Multivariate logistic regression and receiver operating characteristic (ROC) analysis were employed to identify and evaluate potential biomarkers for neurological damage.
Significant changes in erythrocyte parameters were observed in lead-poisoned children. Upon further analysis, increased mean corpuscular hemoglobin concentration (MCHC) and red cell distribution width-standard deviation (RDW-SD) interaction values were found to be significantly associated with neurological impairment. The MCHCRDW-SD interaction model demonstrated an AUC of 0.76, indicating its effectiveness in reflecting neurological damage. Additionally, the MCHCRDW-SD Interaction value showed weak or no correlation with other erythrocyte parameters, suggesting its independence as an indicator.
Our findings propose the increased MCHC*RDW-SD interaction value as a robust and independent biomarker for detecting neurological impairment in lead-poisoned children. This underscores the potential of utilizing specific erythrocyte parameters for screening the neurotoxic effects of lead exposure in pediatric populations.
铅对儿童的神经毒性作用可对发育中的神经系统产生长期而深远的影响。本研究旨在确定一种可靠且易于获取的生物标志物,以监测铅中毒儿童的神经损伤。
我们分析了356名铅中毒儿童的血液学数据,并将其与年龄和性别匹配的健康对照进行比较。采用多变量逻辑回归和受试者工作特征(ROC)分析来识别和评估神经损伤的潜在生物标志物。
在铅中毒儿童中观察到红细胞参数的显著变化。进一步分析发现,平均红细胞血红蛋白浓度(MCHC)和红细胞分布宽度标准差(RDW-SD)的交互作用值增加与神经损伤显著相关。MCHCRDW-SD交互作用模型的曲线下面积(AUC)为0.76,表明其在反映神经损伤方面的有效性。此外,MCHCRDW-SD交互作用值与其他红细胞参数的相关性较弱或无相关性,表明其作为指标的独立性。
我们的研究结果表明,增加的MCHC*RDW-SD交互作用值是检测铅中毒儿童神经损伤的一种可靠且独立的生物标志物。这凸显了利用特定红细胞参数筛查儿童铅暴露神经毒性作用的潜力。
