The mechanisms by which hepatitis C virus (HCV) induces chronic infection in the vast majority of infected individuals are unknown. Sequences within the HCV E1 and E2 envelope genes were analyzed during the acute phase of hepatitis C in 12 patients with different clinical outcomes. Acute resolving hepatitis was associated with relative evolutionary stasis(More)
BACKGROUND Mood and anxiety symptoms in chronic hepatitis C (CHC) may be related to the patient awareness of the diagnosis and prognosis, to side effects induced by interferon (IFN)-alpha treatment, as well as to substance abuse. However, the observation of metabolic alterations in patients with CHC has led to hypothesize a direct effect of hepatitis C(More)
We investigated the course of distinct episodes of acute non-A, non-B (NANB) hepatitis in three polytransfused thalassaemic children. In each case, the first episode was associated with the appearance of serum hepatitis C virus (HCV) RNA and anti-HCV seroconversion. The second episode was accompanied by the reappearance of HCV viraemia, which in two(More)
The prevalence of serum markers of primary delta infection was determined in 532 patients with acute benign hepatitis B seen in Italy, and in 111 patients with fulminant hepatitis B seen in Italy, France and England. Patients with fulminant hepatitis had significantly higher prevalence of delta markers (43/111, 39%) than did those with benign hepatitis(More)
Sera from 74 hepatitis B surface antigen-positive individuals, who presented with acute hepatitis delta virus (HDV) infection which ran a self-limited course in 58 and progressed to chronicity in 16, were tested over time for HDV markers. In self-limited disease the serum pattern varied from early HD-antigenaemia followed by IgM and IgG anti-HD(More)
Antibody to the hepatitis delta virus (anti-delta) was detected in 112 out of 2487 (5%) individuals fortuitously found to have the hepatitis B surface antigen (HBsAg) in the blood. Liver function was impaired in 38% (43 of 112) of the anti-delta-positive carriers but in only 9% (215 of 2375) of the anti-delta-negative subjects (p less than 0.001). Liver(More)
