摘要
目的探讨人类疱疹病毒8型(Httv-8)ORE75基因亚型,与Kaposi肉瘤不同临床分型及侵袭性的相关性。方法对25例新疆Kaposi肉瘤石蜡包埋组织进行HHV-8DNA抽提、扩增及双向测序,使用Clustal W软件和PHYLIP软件包对测序结果进行发生学分析,从而确定HHV-8ORF75基因亚型。结果25例Kaposi肉瘤中,21例HHV-8阳性,阳性率为84%,其中7例AIDS相关型Kaposi肉瘤患者HHV-8均阳性。21例HHV-8阳性患者中,18例为HHV-8 ORF75 A亚型,3例为C亚型;不同亚型间Kaposi肉瘤患者有无黏膜损害及临床分型的分布差异均无统计学意义(P〉0.05)。结论新疆Kaposi肉瘤患者感染HHV-8 ORF 75亚型属于A亚型和C亚型,HHV-8 ORF 75不同亚型可能与新疆Kaposi肉瘤黏膜损害及临床分型无关。
Objective To profile the subtypes of open reading frame 75 (ORF75) of human herpesvims 8 (HHV-8) in patients with Kaposi's sarcoma, and to evaluate their relationship with clinical phenotypes and invasiveness of Kaposi' s sarcoma. Methods Twenty-five paraffin-embeded tissue specimens of Kaposi's sarcoma were collected in the Department of Dermatology, People's Hospital of Xinjiang Uygur Autonomous Region. DNA was extracted fi'om these specimens, and nested-PCR was performed to amplify HHV-8 DNA followed by bi-directional sequencing. Phylogenetic analysis was carded out by using the software DNASTAR, Clustal W program and PHYLIP package so as to identify the ORF75 subtype of HHV-8. Results HHV-8 DNA was detected in 21 (84%) out of the 25 samples, and 7 cases of AIDS-associated Kaposi's sarcoma were all positive for HHV-8. Among the 21 patients carrying HHV-8 DNA, 18 were positive for subtype A ORF75, 3 for subtype C ORF75. The ORF75 subtypes had no significant correlation with the presence of rnucosal lesions or clinical phenotypes of Kaposi' s sarcoma. Conclusions The majority of patients with Kaposi's sarcoma in Xinjiang are infected with HHV-8 of ORF 75 subtype A and C. The ORF75 subtypes of HHV-8 have no correlation with the presence of mucosal lesions or clinical ohenotypes of Kanosi's sarcoma.
