 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).
