Mucosal high-risk human papillomavirus (HPV) types benefit differently from the immunocompromised status of the host. So far it is not known whether a similar scenario holds for the large group of the β and γ cutaneous HPV types that appear to be present at several anatomical sites.
The presence of β (n=43) and γ (n=30) HPVs in the anal samples of 66 HIV-positive and 153 HIV-negative anonymized men who have sex with men (MSM) was determined by multiplex PCR, using type-specific primers and bead-based hybridization (Luminex technology).
The prevalence of β and γ HPV infection was 65.6% and 68.2%, respectively, among HIV-positive MSM and 59.1% and 57.7%, respectively, among HIV-negative MSM. β-2 and γ-10 were found to be the most prevalent species in both groups. The prevalence of infection with HPV types of the species β-1 (P=0.02), β-3 (P=0.002), γ-6 (P=0.002), and γ-7 (P=0.02) was higher in HIV-positive than HIV-negative men. In contrast, the β-2 species was equally distributed in the two groups, while the γ-10 species was slightly affected by HIV status.
These findings provide evidence that impairment of the host's immune surveillance impacts β and γ HPV infections differently.
黏膜高危型人乳头瘤病毒(HPV)类型从宿主免疫功能低下状态中获益的方式有所不同。目前尚不清楚对于似乎存在于多个解剖部位的大量β和γ皮肤型HPV类型,是否也存在类似情况。
通过多重聚合酶链反应(PCR),使用型特异性引物和基于磁珠的杂交技术(Luminex技术),检测了66名感染人类免疫缺陷病毒(HIV)呈阳性和153名HIV呈阴性的男男性行为者(MSM)肛门样本中β(n = 43)和γ(n = 30)HPV的存在情况。
在HIV阳性的MSM中,β和γHPV感染率分别为65.6%和68.2%,在HIV阴性的MSM中分别为59.1%和57.7%。β-2和γ-10被发现是两组中最常见的类型。HIV阳性男性中β-1(P = 0.02)、β-3(P = 0.002)、γ-6(P = 0.002)和γ-7(P = 0.02)型HPV的感染率高于HIV阴性男性。相比之下,β-2类型在两组中分布均匀,而γ-10类型受HIV状态的影响较小。
这些发现提供了证据,表明宿主免疫监视功能受损对β和γHPV感染的影响不同。
