Lymphoblastoid interferon therapy in chronic hepatitis C: biochemical, virological and histological evaluation of two different doses.

Sixty patients of both sexes with biopsy-proven chronic hepatitis C were randomized to receive lymphoblastoid interferon 3 MU or 6 MU three times weekly for 6 months. A follow-up period of 3 months at the end of the therapy was scheduled. Thirty-two patients (53.

[Therapy of chronic non-A, non-B hepatitis with interferon alfa-2B. A controlled clinical study and long-term follow-up].

In order to assess the efficacy of alpha-2b interferon (r-IFN) in the treatment of non-A non-B chronic hepatitis, 30 patients were randomised to receive r-IFN (3 MU subcutaneously three times a week for 24 weeks) or no therapy. A total of 21 males and 9 females, aged between 24-66 years old and who had had increased transaminase levels for at least one year, were included in the study. Three patients were ex-drug addicts and 6 had received blood transfusions whereas the cause of the infection in the remaining 21 patients was unknown.

[The renin-angiotensin-aldosterone system in liver cirrhosis].

The role of the RAA system in the genesis of ascites in liver cirrhosis patients is not yet perfectly clear. The present study was conducted on 176 cirrhosis patients in order to investigate RAA system function, to assess the changes taking place in the various stages of the disease and to correlate such changes with the various kidney function parameters. The patients were divided into 3 groups as follows: Group I: patients without ascites on admission and with no history of the condition; Group 2: patients with ascites of recent onset and/or response to diuretic treatment; Group 3: patients with ascites not responsive to diuretic treatment.

[Changes in antidiuretic hormone (ADH) in liver cirrhosis with resistant ascites].

The pathogenetic role of ADH in determining hyponatremia in patients with liver cirrhosis is still much debated. Osmotic stimuli are not able to inhibit secretion of ADH in refractory ascites and under such conditions the reduction in effective plasma volume has been put forward as the main cause. Twenty patients with liver cirrhosis and refractory ascites were studied before and during extraction-concentration-reinfusion (ECR) of ascitic fluid by means of Rhodiascit.
