Abstract

Interferon-gamma (IFN-gamma) titres in 20 patients with active Behçet's disease were examined and compared with those of 20 normal donors. Sera from Behçet's disease patients revealed an IFN-gamma increase but no correlation between IFN level and natural killer (NK) activity. The analysis of lymphocyte subsets by monoclonal antibodies registered an increase of CD8+ T subpopulation and cells co-expressing CD8(+)-Leu7a+ markers. Moreover, a high number of cells expressing CD25+ and HLA-DR+ phenotype has been noted in patients with active Behçet's disease. Serological analysis showed a high level of IgG antibodies to HSV-1. The increase of IFN-gamma titre, the high number of activated T cells and the increasing level of IgG antibodies to HSV-1 are important manifestations during the active stage of Behçet's disease. These findings are discussed in relation to the immunopathogenesis of Behçet's disease.

摘要

检测了20例活动期白塞病患者的干扰素-γ(IFN-γ)滴度,并与20名正常供者的进行比较。白塞病患者的血清显示IFN-γ升高,但IFN水平与自然杀伤(NK)活性之间无相关性。用单克隆抗体分析淋巴细胞亚群显示CD8 + T亚群以及共表达CD8(+) - Leu7a +标志物的细胞增加。此外,在活动期白塞病患者中发现大量表达CD25 +和HLA-DR +表型的细胞。血清学分析显示抗单纯疱疹病毒1型(HSV-1)的IgG抗体水平很高。IFN-γ滴度升高、活化T细胞数量增加以及抗HSV-1的IgG抗体水平升高是白塞病活动期的重要表现。结合白塞病的免疫发病机制对这些发现进行了讨论。
