在日本某HTLV-I流行地区对1120名HTLV-I血清阴性成人进行了11年随访,发现23名HTLV-I血清转换者。血清转化后第一年抗htlv - i几何平均滴度为1:453;在2-10年的随访中,每个受试者的滴度没有明显变化。HTLV-I前病毒DNA载量在15个血清转换器中被量化,并观察到广泛的水平范围-从<10到bb1000拷贝/105外周血单个核细胞。然而,在个体受试者中,HTLV-I前病毒DNA载量在几年内没有明显变化。因此,成人HTLV-I病毒转化者的前病毒DNA载量和体液反应在初次感染后的几年内趋于稳定。另外,1例患者在抗体血清转化前HTLV-I前病毒DNA检测呈阳性,提示社区获得性感染存在窗口期
Twenty-three human T lymphotropic virus type I (HTLV-I) seroconverters were identified among 1120 HTLV-I–seronegative adults followed up for 11 years in an area of Japan endemic for HTLV-I. The geometric mean titer of anti–HTLV-I was 1:453 in the first year after seroconversion; the titer of each subject did not change significantly during 2–10 years of follow-up. HTLV-I proviral DNA load was quantified in 15 seroconverters, and a broad range of levels was observed—from <10 to >1000 copies/105peripheral blood mononuclear cells. However, there was no obvious change in HTLV-I proviral DNA load over several years within individual subjects. Therefore, both proviral DNA load and humoral response in adult HTLV-I seroconverters were shown to stabilize within a few years after initial infection. In addition, 1 subject tested positive for HTLV-I proviral DNA before antibody seroconversion, which suggests the existence of a window period in community-acquired infection
