Diabetes mellitus has been reported to have an increased prevalence and to be associated with more severe fibrosis in patients with chronic hepatitis C. We evaluated the prevalence of diabetes mellitus in patients with chronic hepatitis B or C as well as the possible association between presence of diabetes and extent of liver fibrosis. In total, 434 consecutive patients with histologically documented hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (n = 174) or chronic hepatitis C (n = 260) were studied. The relationships of diabetes and epidemiological, somatomorphic, laboratory and histological patient characteristics were evaluated. Liver histological lesions were blindly evaluated according to the Ishak's classification. Diabetes was present in 58 (13%) patients, without any difference between those with chronic hepatitis B (14%) or C (13%). Diabetes was observed significantly less frequently in patients with fibrosis score 0-2 (7.7%) than 3-4 (10.4%) than 5-6 (29.2%) (P < 0.001). The presence of diabetes was independently associated with higher gamma-glutamyl-transpeptidase (GGT) levels and more severe fibrosis or presence of cirrhosis (P < 0.001) as well as with presence of hepatic steatosis and increased serum triglycerides levels (P < 0.02). In the noncirrhotic patients, diabetes was significantly associated with older age and higher GGT levels, but not with the extent of fibrosis. In conclusion, diabetes mellitus is observed in more than 10% of patients with either HBeAg-negative chronic hepatitis B or chronic hepatitis C. The presence of diabetes is strongly associated with more severe liver fibrosis, but such an association may be related to the high prevalence of diabetes in patients with cirrhosis.
We evaluated the longitudinal changes of viraemia and predictors of progression in a prospectively followed cohort of 150 untreated patients with HBeAg-negative chronic hepatitis B virus (HBV) infection. According to the first year of follow-up, 85 patients were classified into inactive carrier state and 65 into chronic hepatitis B (CHB). Serum HBV DNA levels were determined at baseline in all patients, at year-1 in carriers or last pretherapy visit in CHB patients and during alanine aminotransferase (ALT) elevations in carriers progressing to CHB. HBV DNA levels at any occasion were > or =80, > or =2000 or > or =20 000 IU/mL in 81%, 23% or 0% of carriers and 100%, 95% or 83% of CHB patients. The cumulative progression rate from carrier to CHB was 11%, 16%, 24% at 2-, 3-, 4 years and was independently associated with higher baseline ALT (always within traditional normal range) and baseline HBV DNA > or =2000 or > or =5000 IU/mL. In 12 carriers progressed to CHB, HBV DNA increased by >1 log(10) IU/mL. During 7.5 months of median follow-up, HBV DNA change > or =1 log(10) IU/mL was observed in 49% of CHB patients. In conclusion, serum HBV DNA levels are detectable in the majority of inactive HBV carriers exceeding 2000 IU/mL in only 23% and 20 000 IU/mL in none of them. Carriers have approximately 15% 3-year risk of progression to CHB, which is associated with higher baseline ALT and viraemia > or =2000-5000 IU/mL, and thus should be closely followed. Approximately 20% of HBeAg-negative CHB patients have HBV DNA <20 000 IU/mL with fluctuations >1 log(10) occurring in many of them.
APRI is significantly associated with the extent of fibrosis, but it does not classify correctly 40-65% of patients with chronic hepatitis C or HBeAg-negative chronic hepatitis B, and thus it cannot replace liver biopsy.
Serum apoptotic caspase activity is strongly associated with the presence of liver injury in patients with HBeAg-negative chronic HBV infection. CK-18 fragment levels seem to be a very useful marker for differentiation between the inactive HBV carrier state and HBeAg-negative chronic hepatitis B, but not for estimation of the severity of liver histological lesions among HBeAg-negative chronic hepatitis B patients.
Moderate or severe steatosis is significantly less frequent in genotype 4 than 3 chronic hepatitis C patients and similar between genotype 4 and 1. In nondiabetic, nonoverweight patients, moderate or severe steatosis is present in only 10-15% of genotype 4 or 1 compared with 40% of genotype 3 patients. Thus, hepatic steatosis in genotype 4 is mostly associated with metabolic factors, similar to those in genotype 1.
Background: Iron overload and hepatitis-C virus (HCV) infection, have been implicated in the evolution of liver disease, in patients with transfusiondependent beta-thalassaemia major (BTM). However, the impact of these factors in late stages of liver disease in adults with BTM, has not been extensively studied. Aims: To investigate serum indices of iron overload, HCV infection and liver disease, in a cohort of 211 adult Greek patients with BTM, in relation with the findings from liver biopsies. Methods: In this cross-sectional study, 211 patients with BTM were enrolled and studied, in relation with HCV infection, ferritin, transaminases, chelation treatment and antiviral treatment. Based on 109 patients biopsied, we correlated liver fibrosis, haemosiderosis and inflammation, with serum indices and HCV status Results: Among all patients, 74.4% were anti-HCV positive (HCV+). Ferritin was positively correlated with transaminases and negatively correlated with age, while it was not significantly different among HCV+ and HCVÀ patients. Among the HCV+ patients, 55.4% reported antiviral treatment, while genotype 1 predominated. In a subfraction of 109 patients, in which liver biopsy was performed, 89% were HCV+ and 11% HCVÀ. Fibrosis was significantly correlated with age (P = 0.046), AST (P = 0.004), ALT (P = 0.044) and inflammation (P < 0.
