Endemic Burkitt lymphoma is associated with Epstein-Barr virus (EBV) and Plasmodium falciparum coinfection, although how P. falciparum exposure affects the dynamics of EBV infection is unclear. We have used a modeling approach to study EBV infection kinetics in a longitudinal cohort of children living in regions of high and low malaria transmission in Kenya. Residence in an area of high malaria transmission was associated with a higher rate of EBV expansion during primary EBV infection in infants and during subsequent episodes of EBV DNA detection, as well as with longer episodes of EBV DNA detection and shorter intervals between subsequent episodes of EBV DNA detection. In addition, we found that concurrent P. falciparum parasitemia also increases the likelihood of the first and subsequent peaks of EBV in peripheral blood. This suggests that P. falciparum infection is associated with increased EBV growth and contributes to endemic Burkitt lymphoma pathogenesis.
地方性伯基特淋巴瘤与爱泼斯坦-巴尔病毒(EBV)和恶性疟原虫共同感染有关,尽管恶性疟原虫暴露如何影响EBV感染动态尚不清楚。我们采用建模方法,研究了肯尼亚疟疾传播率高低不同地区儿童纵向队列中的EBV感染动力学。居住在疟疾高传播地区的婴儿在原发性EBV感染期间以及随后EBV DNA检测期间,EBV扩增率较高,EBV DNA检测持续时间较长,后续EBV DNA检测之间的间隔较短。此外,我们发现同时存在的恶性疟原虫血症也增加了外周血中EBV首次及后续峰值出现的可能性。这表明恶性疟原虫感染与EBV生长增加有关,并促成了地方性伯基特淋巴瘤的发病机制。
