Abstract

Background: Approximately 2% of HerpeSelect herpes simples virus type 2 (HSV-2) IgG enzyme immunoassay (screen assay) sera-positive samples do not confirm using an HSV-2 IgG inhibition assay. Of these, roughly 1.33% are confirmed negative, and a small proportion (0.2%) are indeterminate due to inhibition observed with HSV-1 and HSV-2 lysate. The objective of this study was to assess the relationship between HSV-1 IgG serostatus and HSV-2 IgG confirmation results using the HSV-2 IgG inhibition assay.

Methods: This study included consecutive HSV-2 IgG screen-positive specimens regardless of index value. Specimens were also tested for HSV-1 IgG. The HSV-2 IgG confirmation results from the inhibition assay were evaluated to assess the relationship between inhibition results and HSV-1 serostatus.

Results: Of the 21,006 positive HSV-2 IgG specimens, 13,237 (63%) were also positive for HSV-1 IgG. The proportion of HSV-1 IgG-positive samples among inhibition-indeterminate samples (33 to 40 [83%]) was higher than among inhibition-negative (167 of 279 [60%]) and inhibition-positive (13,041 of 20,691 [63%]) samples. Among HSV-1 IgG-positive samples, the median HSV-1 IgG index was also significantly higher for the inhibition-indeterminate group (median, 48.8) than for the inhibition-negative (median, 30.7) and inhibition-positive groups (median, 31.2; P = 0.00013 and P = 3.1e - 05, respectively).

Conclusion: These findings suggest that HSV-2 IgG inhibition-indeterminate, but not inhibition-negative, results are associated with higher index values of HSV-1 IgG. Further studies are needed to understand other factors associated with inhibition-indeterminate results.

抑制试验检测HSV-1血清状态与HSV-2 IgG确认结果的关系

背景：大约2%的疱疹选择性单纯疱疹病毒2型（HSV-2） IgG酶免疫测定（筛选试验）血清阳性样本不证实使用HSV-2 IgG抑制试验。其中，约1.33%被证实为阴性，小部分（0.2%）由于被HSV-1和HSV-2裂解物抑制而不确定。本研究的目的是通过HSV-2 IgG抑制试验评估HSV-1 IgG血清状态与HSV-2 IgG确认结果的关系。方法：本研究包括连续的HSV-2 IgG筛查阳性标本，不论指标值。同时对标本进行HSV-1 IgG检测。对抑制试验的HSV-2 IgG确认结果进行评估，以评估抑制结果与HSV-1血清状态的关系。结果：21006份HSV-2 IgG阳性标本中，13237份（63%）HSV-1 IgG阳性。在抑制不确定样本中，HSV-1 igg阳性样本的比例（33 ~ 40份[83%]）高于抑制阴性样本（279份中有167份[60%]）和抑制阳性样本（20691份中有13041份[63%]）。在HSV-1 IgG阳性样本中，抑制不确定组的HSV-1 IgG指数中位数（48.8）也显著高于抑制阴性组（30.7）和抑制阳性组(31.2；P = 0.00013和P = 3.1e - 05)。结论：HSV-2 IgG抑制不确定，但非抑制阴性，结果与较高的HSV-1 IgG指标值相关。需要进一步的研究来了解与抑制相关的其他因素-不确定的结果。
