患有镰状细胞病(SCD)的儿童,包括那些没有脑梗塞证据的儿童,认知缺陷的风险增加,这可能会导致学业和社会功能困难。慢性炎症过程是 SCD 的地方病,在包括哮喘在内的常见合并症中很明显。介导炎症过程的细胞因子可能会影响认知。我们对 25 名患有 SCD 的儿童进行了标准化的神经心理学测量,并进行了正常的大脑 MRI 研究,研究了通常与哮喘相关的细胞因子的血浆水平与认知功能之间的关系。患有 SCD 的儿童在认知功能测试中的表现明显低于正常平均值。 Pearson 相关性表明细胞因子(IL-4、IL-5、IL-8 和 IL-13)与执行功能标准化测试之间存在显着负相关关系(r = -.54 至 -.74)。初步证据表明,细胞因子水平与 SCD 儿童的执行功能之间存在关联,表明炎症过程在这些儿童的认知结果中具有潜在作用。
Children with sickle cell disease (SCD), including those without evidence for cerebral infarcts, are at increased risk for cognitive deficits that may contribute to difficulties in academic and social functioning. Chronic inflammatory processes are endemic to SCD and are apparent in common comorbidities including asthma. Cytokines mediating inflammatory processes may influence cognition. We examined the relationship between plasma levels of cytokines commonly associated with asthma and cognitive functioning using standardized neuropsychological measures in 25 children with SCD with normal MRI studies of the brain. Children with SCD performed significantly below the normative mean on tests of cognitive function. Pearson correlations indicated significant negative relations between cytokines (IL-4, IL-5, IL-8, and IL-13) and standardized tests of executive function (r = −.54 to −.74). Preliminary evidence suggests an association between cytokine levels and executive function in children with SCD, indicating a potential role for inflammatory processes in cognitive outcomes in these children.
