| infection with human herpes virus type 8 in an area at high prevalence for hepatitis c virus infection in southern italy. | the campania region is a geographical area of southern italy characterized by high incidence rates of hepatocellular carcinoma and of classic kaposi's sarcoma. epidemiological investigations carried out among different population groups in this region have found high prevalence rates of both hepatitis c virus (hcv) and human herpesvirus type 8 (hhv-8). to assess co-infection rates of hcv and hhv-8, we carried out a cross-sectional seroepidemiological study prevalence in pomigliano d'arco, a heal ... | 2004 | 15117330 |
| distribution pattern of hepatitis c virus genotypes and correlation with viral load and risk factors in chronic positive patients. | hepatitis c virus (hcv) has emerged as a leading cause of chronic hepatitis, liver cirrhosis and hepatocellular carcinoma worldwide. the purpose of this study was to describe the distribution pattern of hcv genotypes in chronic hepatitis patients in the campania region of southern italy and estimate their association with risk factors and viral load. | 2014 | 25170801 |
| hcv infection and oral lichen planus: a weak association when hcv is endemic. | oral lichen planus (olp), an immune-mediated disorder, has been reported as an extra-hepatic manifestation of hepatitis c virus (hcv) infection, especially in hcv hyperendemic areas such as southern europe and japan. the aim of this study was to investigate from an epidemiological standpoint whether hcv infection is an important factor affecting the relative risk of olp in a mediterranean population or whether this relates to the degree of hcv endemicity. two cohorts of olp patients resident in ... | 2004 | 15357654 |
| hcv and gbv-c/hgv infection in hiv positive patients in southern italy. | flaviviridae-hepatitis c virus (hcv) and gb virus c/hepatitis g virus (gbv-c/hgv)--and human immunodeficiency virus (hiv) frequently show similar modes of transmission. hcv and gbv-c/hgv infection was assessed in 134 consecutive patients with evidence of hiv infection, living in campania, italy. data obtained from this cohort were compared with those obtained from 252 age- and sex-matched hcv infected patients without evidence of hiv infection (hcv control group). following enzymatic immunoassay ... | 2001 | 12081097 |
| prevalence of hepatitis c virus genotypes in southern italy. | hcv is ubiquitous. in 50% of all cases it causes chronic hepatitis that often evolves into liver cirrhosis and hepatocellular carcinoma. recently hcv has been classified in 5 genotypes by okamoto. the purpose of this study is to evaluate the prevalence of 5 genotypes in campania, a region of southern italy, where the prevalence of anti-hcv antibodies ranges from 0.87 to 4%, and to evaluate the correlation between the hcv genotypes and the severity of histological damage. one-hundred- and-thirty- ... | 1997 | 9062779 |
| detection of hepatitis c virus-rna by polymerase chain reaction in dental surgeries. | the mean prevalence of anti-hepatitis c virus (hcv) in italy is 0.87%. it reaches 2% in campania, southern italy. approximately 50% of community acquired non-a, non-b (nanb) hepatitis cannot be associated with known parenteral exposure. a recent italian study has shown that the only demonstrable risk factor in 9% of acute c/nanb hepatitis is dental treatment. there are no data on direct contamination by hcv of dental surgeries. possible environmental contamination by hcv-rna was investigated in ... | 1995 | 7536229 |
| epidemiological survey of hepatitis c virus infection in a cohort of patients from a ser.t in naples, italy. | hepatitis c virus (hcv) has infected an estimated 170 million people worldwide, most of whom are chronically infected (60% to 80%). in italy, the estimate of anti-hcv antibody (ab) prevalence, in the general population of northern italy, is 3.2%; in central and southern italy, it is 8.4% to 22.4%. highest prevalence of infection (70% to 90%) is found among intravenous drug users. our purpose is to monitor hcv infection among drug users treated in a drug addiction centre (ser.t) in naples and to ... | 2011 | 21769046 |
