Abstract

Fifteen Japanese patients with Wegener's granulomatosis (WG) were evaluated according to their lymphocyte subset abnormalities. Two colour immunofluorescent flow cytometry was used to distinguish the lymphocyte subset alterations. WG group showed a decrease in the percentage of CD4+ cells and the increase of CD8 + cells. Within the NK cell family, the functionally unidentified CD8 +57 + cells were markedly elevated. The disproportion of thelymphocyte subsets (CD4 +↓ CD8 +57 +↑) were similar to those of Acquired Immunodeficiency Syndrome (AIDS) and AIDS relating complexes (ARC). To assesssilent infection of Human immunodeficiency virus (HIV), the polymerase chain reaction (PCR) wasdone for all patients to selectively amplify specific HIV proviral DNA sequences in peripheral blood mononuclear cells, HIV-1 proviral DNA was not found in any patients but these changes of WG might suggest a possible adaptive response to unknown viral infection.
