conclusions genotype d was the main genotype detected in romanian patients with chronic hbv infection. genotype d presented both bcp and pc mutations more frequently. results we detected two hbv genotypes; a (8.1%) and d (60.5%), and a mixture of genotypes a and d (31.4%) (p < 0.001). basal core promoter (bcp) a1762t/g1764a and precore (pc) g1896a mutations were detected in these romanian patie...

Non-Hodgkin lymphoma (NHL) ranked as the sixth most common cancer in 2016. Its incidence has steadily increased in the past decade. Both environmental and genetic factors can promote the development of NHL. It has been hypothesized that chronic antigenic stimulation, especially due to a virus such as the human immunodeficiency virus, Epstein-Barr virus and hepatitis C virus (HCV), plays an impo...

OBJECTIVE To determine the responsibility of hepatitis B virus (HBV) and hepatitis C virus (HCV) and therapeutic implications in a patient who developed systemic vasculitis. CASE REPORT The case of a 38 year old woman who had a past history of addiction to intravenous drugs and developed systemic vasculitis after infection by HBV and HCV is described. The clinical and laboratory findings subs...

BACKGROUND Past studies have demonstrated that a large population of Cameroonians are afflicted with human immunodeficiency virus (HIV) and/or hepatitis B virus (HBV) demonstrating a need for better prevention programs. We aim to describe the prevalence of HIV, HBV and HIV/HBV co-infection; examine the association between HIV and HBV; and determine risk correlates associated with HIV and HBV tr...

Former illegal blood donation in the past decade has caused HIV outbreaks in some rural areas in China. Other HIV associated virus infections, such as human herpesvirus 8 (HHV8) in such areas are still not well defined. In order to explore HHV8 and HCV seroprevalence and potential risk factors in such areas, a cross-sectional study with 305 HIV positive and 315 HIV negative subjects recruited f...

Childhood Hepatitis B virus (HBV) infection causes both medical and public health challenges. Infants who acquire HBV parentally have up to 90% risk of developing chronic HBV infection. It is now estimated that approximately 10% of worldwide cancers are attributable to viral infection, with the vast majority (>85 %) occurring in the developing world. In this distribution, elevated rate and prev...

INTRODUCTION Reactivation of hepatitis B virus (HBV) infection in patients with past infection has been described in 5% to 10% of individuals undergoing immunosuppressive therapies. No data are available to date on the outcome of patients treated by tumour necrosis factor-alpha (TNFalpha) inhibitors for chronic arthritis with a serological pattern of past HBV infection. The aim of our study was...

OBJECTIVES Health care workers, including dentists, are at the front line for acquiring blood-borne virus infections. This study aimed to investigate the prevalence of hepatitis B, hepatitis C and human immunodeficiency viruses among Iranian dentists. MATERIAL AND METHODS The survey included 1628 dental health care workers who attended the 51st annual Congress of the Iranian Dental Associatio...

background: in patients who are hepatitis b virus (hbv) dna-positive, but hbv surface antigen (hbsag) -negative, the infection is referred to as occult hepatitis b infection (obi). occult hbv infection is harmful when other liver diseases are present, and can aggravate liver damage in in patients with chronic liver diseases. in human immunodeficiency virus (hiv) infection the suppression of vir...

BACKGROUND The data on hepatitis b virus (HBV) infection in immigrants population are scanty. The porpoise of this study was to define the demographic, virological, and clinical characteristics of subjects infected with HBV chronic infection in a cohort of immigrants living in Naples, Italy. METHODS A screening for HBV infection was offered to 1,331 immigrants, of whom 1,212 (91%) (831 undocu...
