Abstract

The SPF10-polymerase chain reaction (PCR)-based line probe assay (LiPA-25) with high analytical sensitivity and specificity for human papillomavirus (HPV) genotyping in clinical samples has been widely used in vaccine and epidemiologic studies. A real-time multiplex PCR assay using type-specific primers (Hybribio-23) with low workload and cost has been developed recently. The study aimed to compare the performance of LiPA-25 and Hybribio-23 in selected 1731 cervical swab and 117 tissue samples, with a focus on 20 common HPV types (14 high-risk: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68/73; 6 low-risk: 6, 11, 42, 43, 44, and 53). The level of agreement of two assays was determined using Cohen's Kappa (κ) statistics. A total of 1296 (74.9%) swab samples were identified as HPV-positive by Hybribio-23 or LiPA-25, of which 814 (62.8%) samples exhibited concordant, 358 (27.6%) showed additional or fewer types (compatible), and 124 (9.6%) were discordant. In addition, the two assays showed a perfect agreement for 20 HPV-combined detection (κ = 0.838) and 17 individual HPV types (all κ > 0.800), a good agreement for HPV31 (κ = 0.792) and 43 (κ = 0.696), and a moderate agreement for HPV42 (κ = 0.504). Hybribio-23 was significantly more sensitive for HPV58, 59, 68/73, 42, 43, and 44, and less sensitive for HPV35 and 66 than LiPA-25 (McNemar's test: all p < 0.05). For 117 HPV-positive tissue specimens, the identification of genotypes was 85.2% identical, 12.2% compatible, and only 2.6% discordant. The agreement for HPV31 (κ = 0.786), 68/73 (κ = 0.742), and HPV53 (κ = 0.742) was good, while for other types (all κ > 0.853) and 20 HPV-combined detection (κ = 0.936) was perfect (all p > 0.05). In conclusion, Hybribio-23 and LiPA-25 are comparable. Hybribio-23 could be used for the detection and genotyping of HPV in cervical samples for epidemiological and vaccine studies worldwide.

摘要

基于SPF10聚合酶链反应（PCR）的线性探针分析（LiPA-25）对临床样本中的人乳头瘤病毒（HPV）基因分型具有较高的分析灵敏度和特异性，已广泛应用于疫苗和流行病学研究。最近开发了一种使用型特异性引物的实时多重PCR分析（Hybribio-23），其工作量和成本较低。本研究旨在比较LiPA-25和Hybribio-23在1731份宫颈拭子和117份组织样本中的性能，重点关注20种常见HPV类型（14种高危型：16、18、31、33、35、39、45、51、52、56、58、59、66以及68/73；6种低危型：6、11、42、43、44和53）。使用科恩kappa（κ）统计量确定两种分析方法的一致性水平。共有1296份（74.9%）拭子样本被Hybribio-23或LiPA-25鉴定为HPV阳性，其中814份（62.8%）样本结果一致，358份（27.6%）显示出额外或更少的类型（兼容），124份（9.6%）结果不一致。此外，两种分析方法在20种HPV联合检测（κ = 0.838）和17种单个HPV类型（所有κ > 0.800）方面显示出完全一致，在HPV31（κ = 0.792）和43（κ = 0.696）方面显示出良好一致性，在HPV42（κ = 0.504）方面显示出中等一致性。与LiPA-25相比，Hybribio-23对HPV58、59、68/73、42、43和44的敏感性显著更高，对HPV35和66的敏感性更低（麦克尼马尔检验：所有p < 0.05）。对于117份HPV阳性组织标本，基因型鉴定的一致性为85.2%，兼容性为12.2%，不一致性仅为2.6%。HPV31（κ = 0.786）、68/73（κ = 0.742）和HPV53（κ = 0.742）的一致性良好，而其他类型（所有κ > 0.853）和20种HPV联合检测（κ = 0.936）的一致性完美（所有p > 0.05）。总之，Hybribio-23和LiPA-25具有可比性。Hybribio-23可用于全球范围内宫颈样本中HPV的检测和基因分型，以进行流行病学和疫苗研究。
