Regional Epidemiology, Burden, and Management of Hepatitis B Virus in the Middle East

Hepatitis delta virus infection in Turkey: A meta-analysis of prevalence

Objectives

Hepatitis delta virus (HDV) infection has been granted orphan disease status by the US Food and Drug Administration and the European Medicines Agency owing to its rarity and relatively limited research and treatment options. Turkey is considered an endemic country for the virus. We aimed to provide a current and updated country- and region-specific HDV infection prevalence.

Methods

In this meta-analysis, we searched databases, including MEDLINE, PUBMED, EMBASE, and UlakBim (Turkish Medical Index) published between January 1, 2006, and December 31, 2022. We included blood donor studies, outpatient clinic studies that comprised patients without cirrhosis, and inpatient clinical studies that comprised patients with cirrhosis. Turkey was divided into three regions: West, Central, and East Turkey.

Results

After a systematic assessment, 41 studies were included. Using a random-effects model, the estimated HDV prevalence among hepatitis B surface antigen-positive blood donors, outpatient clinic, and inpatient clinic patients were 3.37% (confidence interval [CI] 1.99-6.11), 5.05% (CI 4.00-6.23), and 29.06% (CI 10.45-51.79), respectively. The HDV prevalence among outpatient clinic patients in Western, Central, and Eastern regions were 3.38% (CI 2.47-4.44), 2.15% (CI 1.37-3.09), and 9.81% (CI 6.61-13.55), respectively.

Conclusions

East Turkey continues to have a high burden of HDV. Public health efforts, such as screening, should be targeted accordingly.

Epidemiology of Hepatitis B in Saudi Arabia from 2006 to 2021

Background

This study describes the epidemiological pattern of acute hepatitis B virus (HBV) infection in Saudi Arabia from 2006 to 2021. It explores case frequency and the crude incidence rate (CIR) by year of diagnosis, age group, region, gender, and nationality of patients.

Methods

Retrospective data on acute hepatitis B cases diagnosed across 20 regions of Saudi Arabia during January 2006 to December 2021 were obtained from the Saudi Ministry of Health's Statistical Yearbook. Statistical analyses were conducted using SPSS version 20.0, employing both parametric and non-parametric tests.

Results

The highest CIR was reported in the regions of Qunfudah, Jeddah, Tabuk, and Taif (28.6, 25.2, 25.1, and 23.4 per 100,000 people). In contrast, the lowest CIR was documented in the regions of Hail, Qurayyat, Jouf, and Hafr AL-Baten (3.6, 3.5, 2.9, and 1.2 per 100,000 people). Incidence rates were notably elevated in those aged 45 years and above (30.6 per 100,000 individuals), followed by the 15-44 age group (14.2 per 100,000 individuals), and were lowest in children aged 0-14 years (0.8 per 100,000 individuals). Regarding gender differences, HBV infection rates were 1.4 times higher in Saudi males than females and 2.2 times higher in non-Saudi males compared to females. Overall, Saudi nationals had a 4.2 times higher HBV infection rate than non-Saudis during the study period.

Conclusion

This study highlights diverse acute Hepatitis B infection rates across Saudi regions, with higher rates in Qunfudah, Jeddah, Tabuk, and Taif, and lower rates in Hail, Qurayyat, Jouf, and Hafr AL-Baten. Predominance among ages 45+, followed by 15-44, and lowest in 0-14 age groups was observed. Gender variations showed notably higher rates in Saudi and non-Saudi males. The notably higher prevalence among Saudi nationals implies key considerations for public health strategies.

Multidisciplinary consensus recommendations for management of hepatocellular carcinoma in Middle East and North Africa region

Hepatocellular carcinoma (HCC) is a growing health concern projected to cross over a million cases worldwide by 2025. HCC presents a significant burden of disease in Middle East and North African (MENA) countries due to a high prevalence of risk factors such as hepatitis C and B infections and rising incidence of non-alcoholic steatohepatitis and non-alcoholic fatty liver disease. In August 2022, an advisory meeting consisting of experts from 5 MENA countries was convened in an attempt to provide consensus recommendations on HCC screening, early diagnosis, current treatment modalities and unmet medical needs in the region. Data were collected from a pre-meeting survey questionnaire and responses analysed and presented during the advisory meeting. This review summarizes the evidence discussed at the meeting and provides expert recommendations on the management of HCC. The 2022 update of Barcelona clinic liver cancer (BCLC) staging and treatment strategy and its implementation in the MENA region was extensively discussed. A key consensus of the expert panel was that multidisciplinary care is crucial to effective patient management that results in better clinical outcomes and overall survival of the patient. The panel recommended the use of predictive and early response biomarkers to guide clinicians in arriving at more effective therapeutic decisions. The experts also emphasized the role of robust screening/surveillance systems, population-based registries, effective referral pathways and standardization of guidelines to ensure the successful management of HCC in the region.

Knowledge and Attitude of Undergraduate Health Professions Students towards Hepatitis B and C

The current study sought to establish the attitude and knowledge level of medical science students in Tibah University towards hepatitis B and C. A cross-sectional study involving 369 students drawn from the faculties of medicine, dentistry, applied medical sciences, pharmacy, nursing, and medical rehabilitation sciences was conducted where a standardised questionnaire was used to determine the attitude and knowledge level of undergraduate students drawn from the college of medicine in Tibah University, Saudi Arabia, regarding viral infections. With a mean of 0.71, 0.69, and 0.66 and a standard deviation (SD) of 0.24, 0.34, and 0.24 for virology and transmission, symptoms and clinical outcomes, and treatment and prevention, respectively, the knowledge level of the health professions students towards hepatitis B and C infections was significant. The knowledge level about the infections was higher among male students than among female students. Similarly, students in their final years of medical school had significantly higher knowledge levels about hepatitis B and C than their counterparts in their first years of medical school. There was also a positive correlation between the attitude of the health professions students towards the disease and their knowledge levels of the disease. Findings indicate that enhanced instruction on the nature, virology, transmission, symptoms, treatment, clinical outcomes, and prevention of hepatitis B and C can help improve the knowledge levels and attitude of the health professions students towards the disease and its management.

Hepatitis B virus infection in Saudi Arabia and the UAE: Public health challenges and their remedial measures

BACKGROUND

Hepatitis B virus (HBV) infection is a major public health concern globally with higher prevalence in Middle Eastern countries. Both Saudi Arabia and the UAE face critical challenges in HBV treatment and management despite the implementation of a mass vaccination program. This review aimed to understand the gaps and unmet needs related to HBV infection, public health challenges associated with its diagnosis, and treatment barriers in Saudi Arabia and the UAE. Additionally, the review aimed to provide the best practices in the HBV care pathway for effective remedial measures and disease reduction.

METHODS

The literature search was done from Pubmed.

RESULTS

The lack of disease awareness and knowledge about disease transmission among patients and their family members and healthcare professionals, lack of proper screening, underdiagnosis, social stigma, lack of established referral system, and treatment cost are the primary barriers to HBV diagnosis and management.

CONCLUSION

Appropriate healthcare initiatives should be undertaken to lower the disease burden in Saudi Arabia and the UAE.

Knowledge, Attitude and Practice Among Palestinian Healthcare Workers in the Gaza Strip Towards Hepatitis B: Cross-sectional survey

Objectives

Healthcare workers are at high risk of contracting hepatitis B virus (HBV). This survey aimed to identify the gaps and strengths in the knowledge, attitudes and practices of healthcare workers towards HBV to drive appropriate health interventions.

Methods

This cross-sectional study was conducted between March and April 2022. A convenience sample of three at-risk healthcare professions from the major health facilities in Gaza was surveyed. A 40-item self-administered questionnaire was used. Statistical data analysis was conducted using Statistical Package for Social Sciences version 25 to obtain descriptive and inferential statistics via various nonparametric, correlation and regression tests (with P <0.05).

Results

A total of 447 healthcare workers participated in the study. Overall, 105 of the participants (23.5%) demonstrated poor knowledge (below 14/20 points) of HBV, 284 (63.5%) had moderate knowledge (14-17 points) and 58 (13%) showed good knowledge. The majority (n = 367, 82.1%) expressed an excellent attitude. Finally, 287 (64.2%) demonstrated a good level of practice regarding HBV infection. A history of needlestick injury was reported by 233 (52.1%) participants, 170 (73.3%) of whom reported taking appropriate preventive actions after exposure.

Conclusion

The majority of the participants demonstrated overall good knowledge regarding HBV infection. Nonetheless, significant gaps remain in the different aspects of the knowledge, attitude and practice construct that require appropriate awareness campaigns to further limit the spread of this preventable viral infection.

Seroprevalence of Hepatitis B Virus Infection and Its Associated Factors Among Blood Donors in Yemen

Background

In limited-resource countries, the prevalence of hepatitis B virus (HBV) infection can be measured using data taken from blood donors. This study aimed to determine the HBV infection seroprevalence and its associated factors among blood donors in Sana’a Governorate, Yemen.

Methods

A cross-sectional study was conducted on 500 people who donated blood at hospitals located in Sana’a between August and October 2016. The volunteers were aged 18–65 years old and were recruited using convenience sampling. A set of questionnaires was administered through face-to-face interviews. Blood samples from each donor were tested for hepatitis B surface antigens using enzyme-linked immunosorbent assay.

Results

The overall seroprevalence of HBV infection in the blood donors was 2.6%. Participants with a history of dental treatment had 7.80 higher odds (95% confidence interval [CI]: 2.26, 26.71; P = 0.002) for HBV infection. Respectively, blood donors who had history of malaria infection or cupping therapy had 7.48 (95% CI: 1.75, 31.82; P = 0.010) and 7.32 (95% CI: 1.72, 30.83; P = 0.010) greater odds of HBV infection.

Conclusion

The seroprevalence of HBV infection in Sana’a is lower than in other governorates in Yemen. Stakeholders could focus on a history of dental procedure, malaria infection and cupping treatment when strategising about HBV infection prevention and control among blood donors.

Lack of awareness of Hepatitis B screening and vaccination in high-risk groups

Background/aim

Hepatitis B virus (HBV) vaccination rates are insufficient in high-risk patients worldwide. This study aimed to investigate the screening, immunization, and vaccination rates in three high-risk groups for HBV infection: allogeneic hematopoietic stem cell transplantation (AHSCT), renal transplantation (RT), and chronic hepatitis C (CHC) groups.

Materials and methods

The serological data of consecutive patients between 2014 and 2019 were reviewed using the hospital database.

Results

The HBV screening rates were 100.0%, 90.4%, and 82.4% in the AHSCT, CHC, and RT groups, respectively (p = 0.003). The immunization rates against HBV through either previous exposure or vaccination were 79.5%, 71.7%, and 46.5% in the AHSCT, RT, and CHC groups, respectively (p < 0.001). The HBV vaccination rate was significantly low in the CHC group (71.5%, 69.0%, 34.6% in the AHSCT, RT, and CHC groups, respectively, p < 0.001). If patients lost their immunity due to immunosuppressive therapy were accounted, the vaccination rates increased to 95.2% in the AHSCT group and 72.9% in the RT group. The rate of annual screening for HBV status was 97.9% in the AHSCT group, but it was only 23.9% in the RT group.

Conclusion

HBV screening and vaccination rates were significantly lower in the RT and CHC groups than in the AHSCT group.

Comparative serologic profiles of hepatitis B Virus (HBV) between HIV/HBV co-infected and Hbv mono-infected patients in Ile-Ife, Nigeria

Hepatitis B virus (HBV) infects about 2 billion people globally and accounts for mortality of about 800,000 from liver cirrhosis and hepatocellular carcinoma. Sub-Saharan Africa accounts for 70% of the Human Immunodeficiency Virus (HIV) global burden. HIV/HBV co-infection results in the early development of HBV complications, alterations of serological biomarkers of HBV. Two hundred and fifty patients with HIV/AIDS were screened for HBV and 20 (8%) were identified. The same number of HBV mono-infected individuals were recruited into the study and subsequently, HBV serological profiles which include HBsAg, HBsAb, HBeAg, HBeAb, HBcAbIgM, and HBcAbIgG were assayed using HBV ELISA kits. Mean age of patients in the HBV/HIV cohort was 45.5 years while the HBV mono-infected infected cohort was 30.5 years. The majority of the HBV/HIV co-infected individuals were females (85%). The frequency of HBeAg among HIV/HBV co-infected cohort was 25% and 15% for HBV mono-infected, while the frequency of HBeAb was higher (60%) among the cohort of HBV/HIV co-infected patients in comparison with the HBV mono-infected cohorts (50%). Two patients among the HIV/HBV co-infected cohort have the isolated anti-HBcAg serologic pattern. The study broadened the available evidence of comparative serologic profiles of Hepatitis B virus between cohorts of HBV/HIV co-infected individuals and HBV mono-infected patients in Nigeria.

Hepatitis B Vaccination Status and Associated Factors Among Healthcare Professionals Working in Health Centers at Akaki Kality Subcity of Addis Ababa, Ethiopia: A Cross-Sectional Study

Background

People at high risk for hepatitis B virus include healthcare workers in contact with blood and human secretions. Hepatitis B virus is unique compared to other sexually transmitted infections because a highly efficacious vaccine exists. However, there have been few studies conducted around the vaccination status of hospital healthcare workers in Ethiopia. Little is known about vaccination penetration among healthcare professionals working in health centers in Ethiopia.

Objective

To assess hepatitis B vaccination status and associated factors among healthcare professionals working in health centers of Akaki Kality, Addis Ababa, Ethiopia.

Methods

A facility-based cross-sectional study was conducted. Using simple random sampling, 528 healthcare workers were selected. Data were collected using a pre-tested, structured self-administered questionnaire. Data were entered into Epi-data and analyzed using SPSS version 20. Multivariable binary logistic regression analysis was used to identify the significant associations. Adjusted odds ratios were computed to measure the strength of association, with statistical significance considered at p< 0.05.

Results

Among 505 respondents, only 244 (48%) had ever received a hepatitis B vaccine. Monthly income, religion, age, working unit and educational level were found to be statistically associated with vaccinated status.

Conclusion

This study showed that the percentage of healthcare professionals who had received a hepatitis B vaccination was very low. This is a serious public health concern and a challenge for a country with high prevalence of hepatitis B infection. There is a need to promote hepatitis B screening and vaccination among healthcare professionals. The government must play its part by increasing healthcare budgets and prioritize hepatitis B prevention by establishing a national awareness campaign, and making screening and vaccination services available at all public health centers.
