title: Distinctive increases in HLA-DR+ and CD8+57+ lymphocyte subsets in Wegener's granulomatosis.
abstract: Lymphocyte subset abnormalities have been observed in a series of patients diagnosed with Wegener's granulomatosis (WG). Fifteen patients with WG were evaluated for lymphocyte subset abnormalities by two-color immunofluorescence flow cytometry. The WG group showed a decrease in CD4+ cells and an extraordinary increase in HLA-DR+ cells. The average percentages of HLA-DR+ cells of the normal group and WG group were 11.0 +/- 4.0 and 40.5 +/- 13.9% (CD3+HLA-DR+ = 20.3 + 9.4%). Within the CD8 family, CD8+57+, CD8+38+ and CD8+HLA-DR+ cells were markedly elevated. Our findings differ from other series which reported that the lymphocyte subsets in the peripheral blood of patients with WG were normal.
