UNLABELLED HCV infection is common among patients with end-stage renal disease (ESRD) on hemodialysis, and it has been considered an independent risk factor for mortality in this setting. Although liver biopsy in ESRD patients with HCV infection is useful before kidney transplantation, it carries a high risk of complications. We sought to assess the(More)
BACKGROUND Recently it has been found that iron is an important element in the natural history of hepatitis C. Serum markers of iron stores are frequently increased in chronic hepatitis C virus (HCV)-infected carriers but the real impact of the hepatic iron overload is poorly understood. The purpose of the present paper was to determine the prevalence of(More)
Hepatitis B virus (HBV) serum markers (HBsAg, anti-HBs, anti-HBc) and antihepatitis C antibody (anti-HCV) were prospectively followed in haemodialysis and CAPD patients. From January 1987 to January 1990, 185 patients on haemodialysis and 124 on CAPD were analysed. Among patients susceptible to HBV (69 on haemodialysis and 70 on CAPD), there were 17 HBsAg(More)
AIM To assess the diagnostic value of modified cutoffs for aspartate aminotransferase to platelet ratio index (APRI) to predict significant liver fibrosis in human immunodeficiency virus (HIV)/hepatitis C virus (HCV) patients. PATIENTS AND METHODS This retrospective cross-sectional study included consecutive patients with HIV/HCV co-infection who(More)
The distribution of hepatitis C virus (HCV) genotypes in patients on hemodialysis and in kidney transplant recipients was compared with that observed in a control group composed of HCV-infected individuals from the general population. A total of 340 patients were included in the study: 46 with end-stage renal disease on regular hemodialysis treatment, 22(More)
BACKGROUND Steatosis occurs frequently in hepatitis C. However, the mechanisms leading to this lesion are still unknown, and the role of steatosis in the progression of the disease remains controversial. The aim of the present paper was to determine the prevalence of steatosis in hepatitis C and its association with hepatitis C virus (HCV) genotype, viral(More)
Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease, which predominantly affects women under 50 years old. Although liver disease is not included in the diagnostic criteria, abnormal liver tests are common among patients with SLE and, in a significant proportion of those patients, no other underlying condition can be identified. We(More)
INTRODUCTION Although various studies have been published regarding the treatment of chronic hepatitis C (CHC) with peginterferon (Peg-IFN) and ribavirin, little is known regarding the real impact of gender on the characteristics that influence the effectiveness and safety of antiviral treatment for CHC patients. The objective of this study was to evaluate(More)
INTRODUCTION The high prevalence of chronic hepatitis C (CHC) and its consequent cirrhosis has been associated with bone fragility. Whether CHC may cause bone and mineral abnormalities in the absence of hepatocellular dysfunction is still unknown. In this study we aimed to determine the prevalence of osteoporotic vertebral fractures and low BMD measurements(More)
The hepatitis B virus (HBV) can be transmitted in the dialysis setting through blood transfusions and environmental surfaces. Transfusion related hepatitis C virus (HCV) infection is very well known, but only recently the environmental transmission of this virus was postulated. In order to study the prevalence, mechanisms of transmission, and the ALT(More)
