CD8 lymphocytosis and pseudotumoral splenomegaly in HIV infection.
Three patients infected with human immunodeficiency virus (HIV) presented with pseudotumoral splenomegaly, CD8 lymphocytosis (3.5-5.1 x 10(9)/l), and hypergammaglobulinaemia. Spleen and bone marrow showed diffuse CD8 lymphocyte and plasma-cell infiltration. Amplification of the T-cell-receptor gamma chain gene did not reveal any clonal T-cell population. Phenotypic analysis showed a predominance of CD8/CD57 suppressor T cells with expression of activation markers (DR and CD38). No cytotoxic T lymphocytes specific for HIV could be detected. The three patients shared the HLA haplotype A1, B8, DR3. The association with this haplotype suggests a genetically determined host immune response to HIV.
