An altered anti-Epstein-Barr virus (EBV) serologic profile preceding diagnosis is associated with an increased risk of Hodgkin lymphoma. It is unknown whether this atypical pattern predicts Hodgkin lymphoma risk further subdivided by determination of EBV in tumor cells. A nested case-control study of 128 incident Hodgkin lymphoma cases and 368 matched controls from active-duty military personnel with archived serum in the US Department of Defense Serum Repository was conducted to determine whether a panel of anti-EBV antibody titers differed in EBV(+) and EBV(-) Hodgkin lymphoma. Among 40 EBV(+) Hodgkin lymphoma cases and matched controls, statistically significant increased risks were associated with elevated anti-EBV VCA IgG antibody titers (relative risk = 3.1; 95% confidence interval [CI], 1.1-8.7), and an anti-EBNA-1/anti-EBNA-2 antibody ratio ≤ 1.0 versus > 1.0 (relative risk = 4.7; 95% CI, 1.6-13.8). In contrast, no significant associations were found among 88 EBV(-) Hodgkin lymphoma cases relative to their matched controls. In case-case analysis, EBV(+) disease was significantly associated with a low anti-EBNA-1/anti-EBNA-2 antibody ratio. This distinctive serologic response to EBV latent antigens, indicative of immune dysfunction in other clinical settings, is associated with an increased risk of developing EBV(+) but not EBV(-) Hodgkin lymphoma.
在诊断前,EB 病毒(EBV)血清学特征发生改变与霍奇金淋巴瘤(Hodgkin lymphoma)的风险增加有关。目前尚不清楚这种非典型模式是否可以进一步预测 EBV 阳性和 EBV 阴性霍奇金淋巴瘤的风险,具体取决于肿瘤细胞中 EBV 的检测。本研究在美国国防部血清库中进行了一项嵌套病例对照研究,纳入了 128 例新确诊的霍奇金淋巴瘤病例和 368 例匹配对照,这些对照来自现役军人,血清样本被存档。本研究旨在确定 EBV 阳性和 EBV 阴性霍奇金淋巴瘤的 EBV 抗体滴度是否存在差异。在 40 例 EBV 阳性霍奇金淋巴瘤病例和匹配对照中,与 EBV 阳性霍奇金淋巴瘤相关的显著风险因素包括 EBV VCA IgG 抗体滴度升高(相对风险=3.1;95%置信区间[CI],1.1-8.7),以及 EBVNA-1/EBVNA-2 抗体比值≤1.0 与>1.0 相比(相对风险=4.7;95% CI,1.6-13.8)。相比之下,在 88 例 EBV 阴性霍奇金淋巴瘤病例与匹配对照之间未发现显著相关性。在病例对照分析中,EBV 阳性疾病与低 EBVNA-1/EBVNA-2 抗体比值显著相关。这种针对 EBV 潜伏抗原的独特血清学反应在其他临床环境中提示免疫功能障碍,与 EBV 阳性但 EBV 阴性霍奇金淋巴瘤的风险增加有关。
