To investigate the characteristics of women developing cervical intraepithelial neoplasia who had had a vaccination against human papillomavirus (HPV).
A retrospective cohort study was carried out of women diagnosed with moderate or severe cervical dysplasia (CIN2+) in four Italian centers between 2015 and 2017. All women included had had previous bivalent or quadrivalent vaccination against HPV.
The present study included 43 patients affected by CIN2+. The median age was 28 (range, 21-41) years. Ten (23.3%) patients did not have a diagnosis of specific HPV type(s) involved: high-risk HPV was detected in 7 (16.3%) women while HPV testing was negative in 3 (6.9%) women. Lesions related to HPV16 were found in two patients. HPV types covered by nonavalent vaccination were diagnosed in 27/33 (81.8%) women. HPV types not covered by nonavalent vaccination were diagnosed in 6 (18.2%) women. Co-infections are most commonly detected in women with HPVs other than those included in the nonavalent vaccination (P=0.024).
Cervical dysplasia occurring after HPV vaccination is a rare condition. Theoretically, nonavalent vaccination should improve protection against more than 80% of HPV-related lesions compared to other vaccines.
研究接种人乳头瘤病毒(HPV)疫苗后发生宫颈上皮内瘤变的女性的特征。
本研究对 2015 年至 2017 年期间意大利四家中心诊断为中重度宫颈上皮内瘤变(CIN2+)的女性进行了回顾性队列研究。所有纳入的女性均曾接种过二价或四价 HPV 疫苗。
本研究共纳入 43 例 CIN2+患者。中位年龄为 28 岁(范围 21-41 岁)。10 例(23.3%)患者未诊断出特定 HPV 型别:7 例(16.3%)女性检测到高危型 HPV,3 例(6.9%)女性 HPV 检测阴性。2 例患者存在与 HPV16 相关的病变。33 例(81.8%)女性诊断出九价疫苗涵盖的 HPV 型别,6 例(18.2%)女性诊断出九价疫苗未涵盖的 HPV 型别。最常见的是检测到非九价疫苗涵盖的 HPV 型别与其他 HPV 型别的合并感染(P=0.024)。
HPV 疫苗接种后发生宫颈上皮内瘤变是一种罕见情况。理论上,与其他疫苗相比,九价疫苗接种应该能更好地预防超过 80%的 HPV 相关病变。
