PG - 1-8 AB - Electron microscopic studies of peripheral blood mononuclear cells (PBMC) in chronic type C hepatitis revealed several interesting structures after interferon-alpha (IFN-alpha) therapy. Fifteen of 20 patients were treated with IFN-alpha. Tubuloreticular inclusions (TRI) were observed in only one patient who did not receive therapy. In contrast, TRI were observed in 10 of 15 (66.7%) patients who underwent the therapy for 2 weeks to 6 months. Cylindric confronting cisternae (CCC) were identified in the cytoplasm of PBMC in 4 of 16 (25%) patients who underwent the therapy. CCC were found only after IFN-alpha therapy. The appearance of both TRI and CCC in the PBMC was significantly correlated to IFN-alpha therapy. Although there is little evidence about the morphogenesis of TRI and CCC, these structures may be a host response to IFN-alpha induced by hepatitis C virus infection.
