infectious pathogens acts as an endogenous immunosuppressant, which further aggravates the imm~~odeficie~cy state of these patients. We are indebted to Miss G. Schijnhuber for her excellent technical assistance. This work was financially supported by a grant of the Austrian Research Fund ‘Zur Fiirderung der wissenschaftlichen Forschung’, project No. 7475.

Interferon is effective in treating both B- and C-type chronic active hepatitis (CAM) (l-3). However, a number of patients do not respond to this treatment, and criteria for the identification of responders and nonresponders have yet to be established (4). Here we report the preliminary findings of a study in which ten C-virus CAH patients, who failed to respond to recombinant interferon-a treatment (Roferon-Roche. 3 MU three times a week for 4 months and 6 MU three times a week for a further 2 months), were treated,, after a with lymphoblastoid interferon 4-month interval, (Wellferon-Wellcome. 6 MU three times a week for 2

months followed by 3 MU three times a week for 4 months). All subjects had elevated serum enzyme activity (alanine transaminase, ALT, 4-6-times above norma!). Patient sera were not checked for neutralising antibodies against the recombinant interferon alpha (5). As shown in Table 1, ALT values reverted to normal in live patients within 2 months of treatment, and remained normal for the follow-up period of 6 months after discontinuation of therapy. Liver biopsy performed in three of these five patients showed improved histology. The statistical analysis by the McNemar test tends towards significancy of results @ < 0.1 > 0.05).

420 The improvement obtained in our five patients is probably related to the change in interferon preparation and dosage schedule. Recently, lymphoblastoid interferon has been shown to be very effective in HCV hepatitis (6,7). The small number of patients in the present study prevents us from drawing any final conclusion; however, it appears that a second course of treatment with a different interferon preparation can be useful in some CAH
