To study the seroprevalence of Kaposi's sarcoma-associated herpesvirus/human herpesvirus type 8 (KSHV/HHV-8) in 779 Italian blood donors.
STUDY DESIGN/METHODS: Sera were tested for antibodies to a latency-associated nuclear antigen (LANA) and a capsid related protein encoded by ORF65.
Among all Italian donors, 17.7% and 18.7% had antibodies to LANA and ORF65 protein, respectively, and 24.1% had antibodies to at least one antigen. KSHV/HHV-8 seroprevalence was higher in the Po valley and in Sardinia than close to the sub-Alpine Veneto region, Tuscany, or Apulia. KSHV/HHV-8 seroprevalence was almost equally distributed between men and women but increased in the older age groups.
The regional differences and age distribution in seroprevalence agree partially with the incidence of classic KS in Italy. The rarity of classic KS in KSHV/HHV-8-infected subjects and the equal gender distribution of seroprevalence suggest that other cofactors may contribute to KS development in human immunodeficiency virus type 1 (HIV-1)-uninfected individuals.
研究779名意大利献血者中卡波西肉瘤相关疱疹病毒/人类疱疹病毒8型(KSHV/HHV-8)的血清流行率。
研究设计/方法:检测血清中针对潜伏相关核抗原(LANA)和由ORF65编码的衣壳相关蛋白的抗体。
在所有意大利献血者中,分别有17.7%和18.7%的人对LANA和ORF65蛋白有抗体,24.1%的人对至少一种抗原有抗体。波河流域和撒丁岛的KSHV/HHV-8血清流行率高于靠近亚高山威尼托地区、托斯卡纳或普利亚地区。KSHV/HHV-8血清流行率在男性和女性中分布几乎相同,但在老年人群中有所增加。
血清流行率的地区差异和年龄分布与意大利经典卡波西肉瘤的发病率部分相符。在KSHV/HHV-8感染的受试者中经典卡波西肉瘤罕见,且血清流行率在性别上分布均等,这表明在未感染1型人类免疫缺陷病毒(HIV-1)的个体中,可能有其他辅助因素促成卡波西肉瘤的发生。
