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

Hepatitis B knowledge and stigma in the United Arab Emirates

Globally, there are 1.2 million new chronic Hepatitis B Virus (HBV) infections every year. The UAE is a low-endemic region where no previous studies have explored HBV stigma. This study aims to evaluate the UAE's population HBV knowledge, HBV vaccine attitudes, and stigmatizing attitudes towards the HBV infection. A cross-sectional study was conducted to evaluate knowledge and stigma; the previously-developed and validated stigma scale (Hepatitis B Virus - Stigma Scale, HBV-SS) was used. A total of 601 responses were retained for analysis in both python-3 and R. Chi-squared, Mann-Whitney U and Kruskal-Wallis tests were used for bivariate analyses and ordinary least squares (OLS) regression was used for linear modelling. Confirmatory factor analysis (CFA) was conducted, and goodness-of-fit was evaluated. Overall, 77.5%, (n = 466/601) reported having some knowledge regarding HBV, only 19.3% (n = 90/466) had good knowledge regarding HBV, with most gaps occurring with symptoms, complications, and treatment of the infection. However, 84.03% (n = 505/601) were interested in learning more about the virus. Only 57.6% (n = 346/601) were aware of the existence of the vaccine; however, attitudes to it were overwhelmingly positive. Overall, non-stigmatising attitudes dominated; however, both labelling and separating domains highlighted specific items with highly stigmatising attitudes. CFA showed the HBV-SS model to have acceptable/good goodness-of-fit. OLS identified higher knowledge levels among healthcare workers and those with higher perceived knowledge. Only perceived knowledge was a significant predictor of lower stigma beyond the bivariate level. The UAE population has shown low levels of knowledge but overall non-stigmatising attitudes. It is imperative that campaigns focus on improving general population HBV infection and vaccine knowledge while also solidifying the widespread level of vaccine acceptance and non-stigmatising attitudes.

Advancing Health Through Sustainable Development Goals-Saudi Arabia's Mid-Journey Progress and Insights

A critical component of Saudi Arabia's Vision 2030 reform agenda is its alignment with the Sustainable Development Goals (SDGs), particularly SDG 3, which is dedicated to the promotion of health and well-being for all. This narrative review offers a mid-term assessment of Saudi Arabia's progress in attaining these objectives, with a particular emphasis on the public health initiatives and comprehensive healthcare reforms that have been implemented as part of this vision. The Kingdom has accomplished substantial reductions in maternal and neonatal mortality rates, with skilled birth attendance reaching nearly universal levels. Saudi Arabia is a regional leader in the field of infectious diseases, having achieved the 95-95-95 HIV targets and significantly reduced the incidences of tuberculosis and malaria. Additionally, the rates of premature mortality from conditions such as cancer, diabetes, and cardiovascular diseases have decreased as a result of efforts to combat non-communicable diseases. Mental health services have been substantially expanded, which has resulted in one of the lowest suicide rates reported worldwide. Substantial investments have collectively improved the universality and quality of healthcare services in health infrastructure, such as the expansion of primary healthcare centers and the integration of digital health solutions, which have supported these health achievements. Saudi Arabia continues to confront persistent obstacles, including the management of the increase in non-communicable diseases, the mitigation of environmental health risks, and the reconciliation of healthcare access disparities, despite these accomplishments. The review recommends that the social determinants of health be addressed through a sustained commitment to cross-sectoral collaboration, enhanced data collection and utilization for health policy-making, and further integration of technology in healthcare delivery. This review not only emphasizes the Kingdom's successes but also the intricate challenges it has encountered, providing valuable insights into the strategic planning required to maintain health gains and achieve SDG 3 by 2030. Saudi Arabia's innovative approach and robust policy implementation serve as a model for the integration of health priorities into national development frameworks, thereby improving health outcomes and contributing to sustainable development.

Medical students' knowledge, attitude, and practice regarding hepatitis B and C virus infections in Jordan: A cross-sectional study

Background and Aims

We aimed to assess the levels of hepatitis B and C knowledge, attitudes, and practices among medical students in Jordan. A survey included participation from medical students across all faculties in Jordan, from 2022 to 2023.

Methods

The data were analyzed with The R Statistical Software (v4.1.2; R Core Team 2022) using descriptive statistics, and multivariate regression analyses. A p ≤ 0.05 was considered statistically significant.

Results

In this study of 2602 participants, the average age was 21.4, with 52.6% females. Most were fourth-year medical students (19.1%), and 52.3% were in clinical years. The mean knowledge score was 14 (SD ± 2.5) out of 20, categorized as high at 58.84%, and low at 41.16%. The mean practice score was 4.89 (SD ± 1.1) out of 7, with good practice in 65%, and low in 35%. The mean attitude score was 1.6 (SD ± 3.1), categorized as low in 81.7%, and high in 18.3%,. High levels of KAP were associated with gender, year of study, and university. Male respondents had lower knowledge (OR: 0.73; p: 0.001; 95% CI: -0.50 to -0.13), and students in the first to fifth years scored lower than sixth-year students. There were moderate positive associations between knowledge and attitude (r: 0.33, p < 0.001), and weak positive associations between knowledge and practice (r: 0.17, p < 0.001), and attitude and practice (r: 0.133, p < 0.001).

Conclusion

In conclusion, the participants revealed high adherence to some practices and intermediate knowledge levels. Gender, academic year, and university affiliation emerged as significant factors, highlighting the necessity for tailored interventions.

The burden of cirrhosis and other chronic liver disease in the middle east and North Africa (MENA) region over three decades

BACKGROUND

Cirrhosis comprises a significant health challenge in the Middle East and North African (MENA) region impacting healthcare systems and communities. This study sought to investigate trends in the burden of cirrhosis and other chronic liver disease, different etiologies, deaths, and the disability burden utilizing data from the Global Burden of Disease (GBD) database.

METHODS

Analyzing epidemiological trends from 1990 to 2021 across 21 MENA countries, this research utilized data on age-standardized incidence rates (ASIR), age-standardized death rates, and age-standardized disability-adjusted life years (DALYs) to evaluate the burden of cirrhosis and other chronic liver disease. The study also examined national variations and sociodemographic relationships.

RESULTS

The study identified a 114.9% increase in cirrhosis and other chronic liver disease incidence within the MENA region between 1990 and 2021, with 7,344,030 incident cases reported in 2021. The ASIR showed a steeper rise in females (9.6%) compared to males (7.0%). Etiology-specific analysis revealed an increase in the ASIR for MASLD related cirrhosis and other chronic liver disease by 22.2%, while those due to alcohol as well as hepatitis B and C decreased by 28.1%, 59.3%, and 30%, respectively. Despite the rising incidence, overall age-standardized death rates across all etiologies decreased by 54.3%, with DALYs showing a 51.4% decrease during the same period. Country-specific trends varied significantly, with Oman recording the highest annual ASIR increase (0.64%), and Qatar observing the most substantial annual reduction in age-standardized death rates (-2.88%).

CONCLUSION

The study highlights evolving trends in cirrhosis and other chronic liver disease within the MENA region, emphasizing the necessity for comprehensive, etiology, and gender-specific interventions. Despite an increasing incidence, the observed improvements in mortality rates and age-standardized disability burden indicate progress in public health efforts to mitigate cirrhosis's impact. These findings point to the complex nature of cirrhosis outcomes and the urgent need for tailored strategies to manage its increasing burden effectively.

The Efficacy of Post-Exposure Prophylaxis in Infants Born to HBsAg-Positive Mothers: A Single Center Experience in Saudi Arabia

Objectives. Post exposure prophylaxis (PEP) with the hepatitis B vaccine (HBVac) in combination with HBV immunoglobulins (HBIG) significantly minimizes the odds of vertical transmission of HBV to newborn infants. In this retrospective study, we aimed to evaluate the compliance and efficacy of PEP in a tertiary care center in Saudi Arabia. Methods. Infants were tested with HBV serological markers at 7 months of age to assess their PEP protection rate. Results. Out of 13,125 mothers who delivered in KAMC, 105 (0.8%) mothers were found to have HBsAg positive, with a prevalence of 8 per 1000 live births. All infants (n = 100) completed their PEP as per protocol before discharge from the hospital (2 days after delivery). Among infants (n = 59; 56.2%) who were tested at 7 months of age, all (100%) were found to be negative for HBV. Conclusion. PEP achieved 100% efficacy among infants who complied with the study protocol at 7 months of follow-up. The prevalence of hepatitis B among pregnant women was 8 per 1000 live births.

Hepatitis B Management in the Middle East: A Narrative Review of Current Antiviral Treatments

Introduction: Chronic hepatitis B (CHB) is a significant public health issue worldwide, especially in the Middle East region. Around 8% to 20% of patients with CHB develop cirrhosis, which may progress to hepatocellular carcinoma. The significant morbidity and mortality associated with CHB denote the importance of high-quality treatment. Methods: We searched the PubMed, Medline, and Cochrane databases from inception to January 2024 to identify relevant studies. Search terms were generated using established treatment guidelines for CHB. We also manually searched the bibliographies of relevant literature to obtain additional papers. Results: In this narrative review, we evaluated the seven currently licensed antiviral therapies for chronic Hepatitis B treatment, including nucleos(t)ide analogs (NAs) and pegylated interferon-alpha (PEG-IFNα). NAs can be divided into two categories: high barrier to resistance and low barrier to resistance. Tenofovir disoproxil fumarate, tenofovir alafenamide, and entecavir are NAs with a high barrier to resistance. Telbivudine has shown promise in providing high efficacy with low viral resistance rates; however, it is not recommended because of insufficient evidence and lack of cost-effectiveness. Lamivudine and adefovir dipivoxil, despite being efficacious, have a low barrier to resistance, the primary reason they are no longer recommended. PEG-IFNα has high efficacy and can be completed in 48 weeks. It is not associated with resistance; however, it has been reported to have several systemic adverse effects. Conclusions: Current first-line NA treatments in the Middle East include entecavir, tenofovir disoproxil fumarate, and tenofovir alafenamide. These drugs are favored over other NAs because of their low rates of resistance. PEG-IFNα has superiority over NAs in inducing a more durable antiviral response and having a finite treatment duration. The main drawback of PEG-IFNα is an unfavorable safety profile.

Current perspectives of viral hepatitis

Viral hepatitis represents a major danger to public health, and is a globally leading cause of death. The five liver-specific viruses: Hepatitis A virus, hepatitis B virus, hepatitis C virus, hepatitis D virus, and hepatitis E virus, each have their own unique epidemiology, structural biology, transmission, endemic patterns, risk of liver complications, and response to antiviral therapies. There remain few options for treatment, in spite of the increasing prevalence of viral-hepatitis-caused liver disease. Furthermore, chronic viral hepatitis is a leading worldwide cause of both liver-related morbidity and mortality, even though effective treatments are available that could reduce or prevent most patients' complications. In 2016, the World Health Organization released its plan to eliminate viral hepatitis as a public health threat by the year 2030, along with a discussion of current gaps and prospects for both regional and global eradication of viral hepatitis. Today, treatment is sufficiently able to prevent the disease from reaching advanced phases. However, future therapies must be extremely safe, and should ideally limit the period of treatment necessary. A better understanding of pathogenesis will prove beneficial in the development of potential treatment strategies targeting infections by viral hepatitis. This review aims to summarize the current state of knowledge on each type of viral hepatitis, together with major innovations.

Clinical Characteristics and Survival of Hepatocellular Carcinoma: Insights from Single-Centre Experience in Saudi Arabia

Background Hepatocellular carcinoma (HCC) represents the most common primary liver malignancy, with a high fatality rate. Relatively, Saudi Arabia has a high incidence of HCC, which is detected in later stages with a poor prognosis. This study aims to investigate the patterns, outcomes, and mortality predictors of HCC in Saudi Arabia. Method A retrospective study from April 2018 to June 2022 included patients with HCC who were diagnosed and managed at the Najran Oncology Center, Saudi Arabia. Through our cancer registry, the patients' clinical, laboratory, radiological, and survival profiles were extracted and analyzed to assess factors associated with mortality using a univariate analysis. The overall survival was calculated by the Kaplan-Meier method. Results The study involved 52 patients with an average age of 74.6 years, predominantly male (the male-to-female ratio is 2.25:1). Viral infections were the primary cause of liver disease in 40.3% (n=21) of patients. At diagnosis, the Child-Pugh class distribution included 23.1% (n=12) patients in class A, 36.5% (n=19) patients in class B, and 40.4% (n=21) patients in class C. Uninodular tumors with ≤50% liver extension were observed in 65.4% (n=34) of cases, and 30.8% (n=16) had portal vein thrombosis. Elevated alpha-fetoprotein (AFP) levels were noted in 48.1% (n=25) of patients, with 23.1% (n=12) exceeding 400 ng/mL. Curative resection was performed in 32.7% (n=17) of patients. The mean survival time was 23±11.8 months (median of 22.5 months, minimum of six, and maximum of 49 months). Relapse occurred in seven (13.5%) cases, while new metastasis occurred in 20 (38.5%) cases. During the study period, 26 (50.0%) patients died. The main cause of death was disease progression in 15 (28.8%) patients. Univariate analysis showed that AFP>400 ng/mL (OR: 4.68; 95% CI: 1.87-11.66, p=0.001), presence of relapse (OR: 0.16; 95% CI: 0.03-0.78, p=0.023), abdominal ascites (OR: 3.38; 95% CI: 1.25-9.14, p=0.016), advanced the Cancer of the Liver Italian Program (CLIP) score (OR: 0.60; 95% CI: 0.41-0.88, p=0.009) were associated with higher mortality rate and were statistically significant. Conclusion Most cases of HCC in our patients were attributed to viral hepatitis, with the majority having liver cirrhosis. Higher AFP (>400 ng/mL), relapse, abdominal ascites, and a higher cancer CLIP score were associated with poorer outcomes. Targeted screening and health education should be advocated; in addition, social determinants should be proactively addressed.

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.
