AB To study the pathogenesis of multicentric Castleman's disease (MCD),
IL-6 producing cells and immune function were investigated in four MCD
patients. The expression of IL-6 mRNA in one MCD lymph node was analysed
by in situ hybridization. IL-6 mRNA expressing cells were scattered in
the interfollicular areas and did not resemble plasma cells. Spontaneous
IL-6 production was detected in the culture supernatants of peripheral
blood mononuclear cells (PBMNC) from four patients. The IL-6 producing
cells among the PBMNC were found to be monocytes by both in situ
hybridization and immunohistochemistry. We evaluated immune function in
four MCD patients. These studies show: (1) a negative PPD skin test in
3/4 patients, (2) decreased IL-2 production in 3/4 patients, (3)
decreased T cell colony formation in 3/4 patients, (4) decreased NK
activity and NK cell number in 2/4 patients, (5) increased soluble IL-2
receptor in 4/4 patients, and (6) decreased CD4/CD8 ratio in 3/4
patients. These results show that MCD resembles, in several ways,
acquired immunodeficiency syndrome (AIDS).
