Immunoglobulin E has been associated with severe malaria suggesting a regulatory role for interleukin (IL)-4 and/or IgE in the pathogenesis of severe malaria. We have investigated possible associations between polymorphisms in the IL-4 repeat region (intron 3) and promoter regions (IL-4 +33CT and - 590CT) in Ghanaian children with severe malaria. There was a significantly higher frequency of IL-4 intron-3 B1B1 genotype in the cerebral malaria group [P < 0.0001, odds ratio (OR) = 8.7]. The genotype and allele frequencies of the IL-4 -590 and +33 polymorphisms did not differ between the four study groups. Carriers of IL-4 +33T/-590T with cerebral malaria had elevated total IgE compared to non-carriers (P = 0.03). Our data suggest that IL-4 and/or IgE play a regulatory role in the pathogenesis of severe or complicated malaria.
免疫球蛋白E与重症疟疾相关,提示白细胞介素(IL)-4和/或IgE在重症疟疾发病机制中起调节作用。我们研究了加纳重症疟疾患儿白细胞介素-4重复区域(内含子3)和启动子区域(IL-4 +33CT和-590CT)多态性之间的可能关联。脑型疟组中IL-4内含子3 B1B1基因型频率显著更高[P < 0.0001,优势比(OR)= 8.7]。四个研究组之间IL-4 -590和+33多态性的基因型和等位基因频率没有差异。与非携带者相比,脑型疟的IL-4 +33T/-590T携带者总IgE升高(P = 0.03)。我们的数据表明,IL-4和/或IgE在重症或复杂疟疾的发病机制中起调节作用。
