Detection of HBs antigen in “anti-HBc alone” positive sera

Journal of Hepatology, 1994
The immunoserological finding "anti-HBc alone" is often observed in defined groups of individuals, such as patients with inflammatory hepatopathies, patients on hemodialyses or with organ transplants, i.v. drug users and homosexuals, but it also occurs in up to 1% of Swiss blood-donors. In order to gain further information about whether "anti-HBc alone"

The underlying mechanisms for the ‘anti-HBc alone’ serological profile

Archives of Virology, 2009
The serological pattern, "anti-HBc alone", characterized by the presence of antibodies against the core antigen of hepatitis B virus (anti-HBc) as the only marker of hepatitis B, is not rare in a diagnostic setting. Depending on the prevalence of HBV infection and the patient group investigated, 1-31% of positive anti-HBc results are isolated positive ...

Presence of low levels of anti‐HBs antibody in so‐called ‘anti‐HBc alone’ subjects

Liver, 2001
Abstract: Background/Aims: The ‘anti‐Hbc alone’ pattern could sometimes be that of subjects who produced anti‐HBs after recovery, but at a lower level than that detectable using commercial assays. This study aimed to test this hypothesis. Methods: A total of 104 ‘anti‐HBc alone’ serum samples, i.e.positive for the anti‐HBc antibody but not for HBsAg ...

Hepatitis B vaccination alone is not adequate for the categorizing of adult subjects with isolated anti‐HBc

Journal of Gastroenterology and Hepatology, 1995
Abstract To evaluate the meaning of isolated antibody to hepatitis B core antigen (anti‐HBc), 88 Chinese subjects with isolated anti‐HBc received rescreening of hepatitis B virus (HBV) markers. Eighty (90.9%) of them were still positive for this antibody and 29 were also found to be positive for antibody to hepatitis B surface antigen (anti‐HBs).

Can the serological status of “anti‐HBc alone” be considered a sentinel marker for detection of “occult” HBV infection?

Journal of Medical Virology, 2008
AbstractSome individuals have “occult” infection with hepatitis B virus (HBV), defined as presence of HBV genome in the serum or liver tissue without HBV surface antigen (HBsAg) in the serum. The aim of this study was to investigate whether serum antibodies against HBV core antigen in isolation (“anti‐HBc alone”) are a useful marker of “occult” HBV in ...

Double hepatitis B virus infection in a patient with HIV/hepatitis C virus coinfection and ‘anti-HBc alone’ as serological pattern

European Journal of Clinical Microbiology & Infectious Diseases, 2005
Reported here is a case of double hepatitis B virus (HBV) infection in an HIV/hepatitis C virus (HCV)-coinfected patient with antibodies against hepatitis B core antigen as the only serological marker (anti-HBc alone). Two different HBV genotypes were identified in this patient.

[Occult HBV infection in patients with anti-HBc positive alone].

Zhonghua shi yan he lin chuang bing du xue za zhi = Zhonghua shiyan he linchuang bingduxue zazhi = Chinese journal of experimental and clinical virology, 2011
This study was designed to explore the incidence rate of occult HBV infection in patients with anti-HBc positive alone and analyze the possible reasons of occult infection.Sera of 183 patients carrying anti-HBc alone(A < or = 0.1) were collected and real-time PCR was used to select samples with HBV DNA positive.

[Hepatitis serological finding "anti-HBc alone", circulating viral DNA and interpretation of findings].

Schweizerische medizinische Wochenschrift, 1993
The immunological finding "anti-HBc alone" (without HBsAg, without anti-HBs) leaves open the question of the state of HBV infection it reflects: a transitory stage of an uncomplicated, eventually prolonged but resolving infection, a chronic or a late state of immunity.

Prevalence of Ac Anti-Hbc Alone Among Pregnant Women at the Yaounde University Teaching Hospital

American Journal of Nursing and Health Sciences
&lt;i&gt;Introduction:&lt;/i&gt; Infection with the Hepatitis B virus (HBV) is a major public health issue; however, Asia and sub-Saharan Africa are the most affected regions. Occult hepatitis B Infection (OBI) refers to the presence of HBV DNA in the serum and/or liver of a patient despite negative HBsAg.

[Significance of "anti HBC alone" serological profile in 284 patients suspicious of being infected with hepatitis B virus].

Annales de biologie clinique, 2007
The "anti-HBc alone" serological profile is a frequent finding in hepatitis B virus infections, but little is known about its clinical significance. The aim of this study was to explore the 'anti-HBc alone' serological profile obtained by immunosorbent assay (ELISA) in 284 patients suspicious of being infected with hepatitis B virus. Sera were screened
