我们报告50例慢性进行性脊髓病的免疫学研究,这些病例与人类T细胞嗜淋巴细胞病毒I型(HTLV-I)和成人T细胞白血病样细胞(HAM)抗体升高有关。这些措施如下:(1)T细胞活化;(2)OKT 4/OKT 8比率增加,主要是由于诱导/辅助T细胞增加和/或抑制/细胞毒性T细胞减少;(3)自然杀伤细胞数量和活性减少;和(4)免疫球蛋白(IgG,IgA)增加。我们的研究结果提供的证据表明,自身免疫事件可能参与HAM的发病机制,并可能在HAM和HTLV-I阳性热带痉挛性轻瘫之间的共同免疫机制的假设有关。
We report the immunological studies of 50 cases with a chronic progressive myelopathy associated with elevated antibodies to human T-cell lymphotropic virus type I (HTLV-I) and adult T-cell leukemia-like cells (HAM). These are as follows: (1) T-cell activation; (2) increase of the OKT4/OKT8 ratio, due mostly to increased inducer/helper T cells and/or decreased suppressor/cytotoxic T cells; (3) decrease of natural killer cell numbers and activity; and (4) increase of immunoglobulins (IgG, IgA). Our results provide evidence that autoimmune events may participate in the pathogenesis of HAM and may be relevant in the hypothesis of common immune mechanisms between HAM and HTLV-I positive tropical spastic paraparesis.
