Helminth infections can potentially confer protection against metabolic disorders, possibly through immunomodulation. In this study, the baseline prevalence of lymphatic filariasis (LF) among subjects without (N = 236) and with (N = 217) coronary artery disease (CAD) was examined as part of the Chennai Urban Rural Epidemiological Study (CURES). The prevalence of LF was not significantly different between CAD(-) and CAD(+) subjects. The LF antigen load and antibody levels indicated comparable levels of infection and exposure between the groups. Within the CAD group, LF(+) and LF(-) subjects had no significant difference in the intimal medial thickness and high-sensitivity C-reactive protein values. However, LF infection was associated with augmented levels of tumor necrosis factor-α and interleukin-6 among CAD(+) subjects. The LF infection had no effect on serum adipocytokine profile. In conclusion, unlike type-2 diabetes, there is no association between the prevalence of LF and CAD and also no evidence of protective immunomodulation of LF infection on CAD in the Asian Indian population.
寄生虫感染可能通过免疫调节对代谢紊乱产生保护作用。在这项研究中,作为 Chennai Urban Rural Epidemiological Study (CURES) 的一部分,检查了无冠心病(CAD)(N=236)和有冠心病(CAD)(N=217)受试者的淋巴丝虫病(LF)的基线患病率。CAD(-)和 CAD(+)组之间 LF 的患病率没有显著差异。LF 抗原负荷和抗体水平表明两组之间感染和暴露的水平相当。在 CAD 组内,LF(+)和 LF(-)受试者的内膜中层厚度和高敏 C 反应蛋白值没有显著差异。然而,LF 感染与 CAD(+)受试者中肿瘤坏死因子-α和白细胞介素-6 的水平升高有关。LF 感染对血清脂肪细胞因子谱没有影响。总之,与 2 型糖尿病不同,在亚洲印第安人群中,LF 的流行率与 CAD 之间没有关联,也没有 LF 感染对 CAD 产生保护性免疫调节的证据。
