Background: Hepatitis D Virus (HDV) causes accelerated liver diseases in patients with Hepatitis B Virus (HBV) infection. There is lack of data about its prevalence, related risk factors and interaction with HBV carriers in our country.
Objectives: The aim of this study was to estimate the prevalence of hepatitis delta and associated risk factors among Hepatitis B surface antigen (HBsAg) and "isolated anti-HBc" profile carriers in central Tunisia.
Patients And Methods: In this cross-sectional study, 540 patients with positive HBsAg and 109 "isolated anti-HBc" profile receiving care in a teaching hospital were tested for the presence of HDV serum-markers using commercially available enzyme immunoassay kit. HBV-DNA was detected by nested PCR in "isolated anti-HBc" profile group.
Results: Prevalence of HDV was 8.1% in HBsAg carriers group, but it was significantly higher in active than inactive hepatitis (30.2% and 4.5%, respectively, OR = 9, 95% CI: [4.48-18.58]). There was no significant association between studied risk factors and HDV infection. In the "isolated anti-HBc" profile group, prevalence of HDV was 4.6% and HBV-DNA had negative result in all patients with positive results for HDV.
Conclusions: Although HDV had low prevalence in our area, it is vital to plan preventive strategies for HDV spread as well as HBV prevention. It is particularly important to suspect HDV infection in active HBV carriers to manage a particularly severe dual infection. HDV infection should be suspected even in negative HBsAg patients having "isolated anti-HBc" profile.

Viral hepatitis are infections that can cause liver damage, become chronic, lead to cirrhosis, hepatocellular carcinoma and ultimately result in death due to their ability to spread in the community through blood and infected body fluids. The aim of this study was to determine the seroprevalence of hepatitis B (HBV), hepatitis C (HCV), and hepatitis D (HDV) transmitted through blood among individuals living in Trabzon province and to examine the factors potentially associated with seroprevalence. This cross-sectional study was conducted in Trabzon province, located in the northeast of Türkiye, including a total of 10 districts, including the central district.

Background: People with HIV (PWH) who are coinfected with hepatitis B virus (HBV) have a higher risk of mortality compared with PWH alone. Populations such as people who inject drugs (PWID) and men who have sex with men (MSM) are particularly at high risk for HBV acquisition; yet, limited epidemiological data from these populations exist on HBV prevalence from low- and middle-income country settings (LMICs).
Methods: We characterized the prevalence and correlates of HBV serological markers in a sample of PWID and MSM with HIV recruited across 15 Indian cities using hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), and hepatitis B surface antibody (anti-HBs).

Background: In Togo, few data are available on viral hepatitis in street adolescents, a vulnerable population due to their lifestyle. The aim of this study was to describe the lifestyle of street adolescents (sexual practices and drug use), to estimate the prevalence of hepatitis B and C viruses, and to describe their HBV immunization profile in Togo.
Methods: A cross-sectional study was conducted in Lomé (Togo) in July 2021.
Low Prevalence of Anti-HBc Antibody and Lack of HBV DNA Among HBsAg-Negative Blood Donors in Iran: A Cross-sectional Study and Review of Literature.

Article Synopsis
- The study focused on occult hepatitis B infection (OBI) in blood donors who tested negative for the hepatitis B surface antigen (HBsAg) in Mashhad, Iran.
- Researchers tested serum samples from 540 HBsAg-negative donors for antibodies against HBV core antigen (anti-HBc) and found that 5.4% were anti-HBc positive, but no HBV DNA was detected in any of the samples.
- The study suggests that blood donations in Iran should be routinely screened for anti-HBc and anti-HBs antibodies, rather than for HBV DNA.
