Occult HBV among Anti-HBc Alone: Mutation Analysis of an HBV Surface Gene and Pre-S Gene [PDF]

Yonsei Medical Journal, 2017
The aim of this study is to investigate the molecular characteristics of occult hepatitis B virus (HBV) infection in 'anti-HBc alone' subjects.Twenty-four patients with 'anti-HBc alone' and 20 control patients diagnosed with HBV were analyzed regarding S and pre-S gene mutations. All specimens were analyzed for HBs Ag, anti-HBc, and anti-HBs.

Serology change-based clinical interpretation of indeterminate serostatus post-hepatitis B virus infection in people living with HIV. [PDF]

PLoS ONE
After hepatitis B virus (HBV) infection in people living with HIV (PLWH), various forms of indeterminate serostatuses, including "isolated anti-HBc (IAHBc)", are observed, but the current interpretation for their HBV immunity seems to be optimistic. This

Clinical significance of "anti-HBc alone" in human immunodeficiency virus-positive patients [PDF]

World Journal of Gastroenterology, 2009
To determine the prevalence and clinical relevance of isolated antibodies to hepatitis B core antigen as the only marker of infection ("anti-HBc alone") among human immunodeficiency virus (HIV) type-1 infected patients. Occult hepatitis B infection frequency was also evaluated.Three hundred and forty eight histories from 2388 HIV-positive patients were

“Anti-HBc alone” in human immunodeficiency virus-positive and immuno-suppressed lymphoma patients [PDF]

World Journal of Gastroenterology, 2009
Hepatitis B virus (HBV) infection is endemic in various parts of the world. A proportion of patients have resolved prior exposure to HBV, as evidenced by the clearance of circulating hepatitis B surface antigen and the appearance of antibody to hepatitis B core antigen (anti-HBc), which could produce protective antibody to hepatitis B surface antigen ...

A new symmetric modular eleven‐level inverter using single and double source unit for low voltage applications with reduced number of switches

IET Power Electronics, EarlyView., 2023
This study introduces a new modular multilevel inverter that can produce five levels of positive voltage using only six power switches and five DC voltage sources. The basic unit is composed of a single‐ and double‐source (SDS) unit. SDS reduces the number of power electronic components, such as the insulated gate bipolar transistors, freewheeling ...

Predictions of the emergence of vaccine-resistant hepatitis B in The Gambia using a mathematical model [PDF]

, 2000
Vaccine escape variants of hepatitis B virus (HBV) have been identified world-wide. A mathematical model of HBV transmission is used to investigate the potential pattern of emergence of such variants.
