RESUMEN

BACKGROUND: Hepatitis B virus (HBV) and latent tuberculosis infection are associated with a significant global burden, but both are underdiagnosed and undertreated. We described the screening patterns and risk factors for co-infection with latent tuberculosis and HBV within a large healthcare system. METHODS: Using data from Kaiser Permanente Southern California during 2008-2019, we described HBV infections, defined as a positive HBV surface antigen, e-antigen, or DNA test, and latent tuberculosis, defined as a positive Mantoux tuberculin skin test or interferon-gamma release assay test. We estimated adjusted odds ratios (aOR) for co-infection among screened adults with either infection. RESULTS: Among 1997 HBV patients screened for latent tuberculosis, 23.1% were co-infected, and among 35,820 patients with latent tuberculosis screened for HBV, 1.3% were co-infected. Among HBV patients, co-infection risk was highest among Asians compared with White race/ethnicity (29.4% vs 5.7%, aOR 4.78; 95% confidence interval [CI], 2.75-8.31), and persons born in a high-incidence country compared with low-incidence countries (31.0% vs 6.6%; aOR 4.19; 95% CI, 2.61-6.73). For patients with latent tuberculosis, risk of co-infection was higher among Asian (aOR 9.99; 95% CI, 5.79-17.20), or Black race/ethnicity (aOR 3.33; 95% CI, 1.78-6.23) compared with White race/ethnicity. Persons born in high-incidence countries had elevated risk of co-infection compared with persons born in low-incidence countries (aOR 2.23; 95% CI, 1.42-3.50). However, Asians or persons born in high-incidence countries were screened at similar rates to other ethnicities or persons born in low-incidence countries. CONCLUSIONS: Latent tuberculosis risk is elevated among HBV patients, and vice versa. Risk of co-infection was highest among persons born in high-incidence countries and Asians. These findings support recent guidelines to increase HBV and tuberculosis screening, particularly among persons with either infection.

RESUMEN

Hepatitis B virus (HBV) care cascade characterisation is important for monitoring HBV elimination progress. This study evaluated care cascade and factors associated with HBV DNA testing and treatment in New South Wales, Australia. HBV care cascade were determined through linkage of HBV notifications (1993-2017) to Medicare and pharmaceutical benefits schemes (2010-2018). Timely HBV DNA testing was within 4 weeks of HBV notification. Multivariate Cox proportional hazards regression evaluated factors associated with HBV DNA testing and treatment. Among 15,202 people with HBV notification, 10,479 (69%) were tested for HBV DNA. A total of 3179 (21%) initiated HBV treatment. HBV DNA testing was more likely among age ≥45 years (adjusted hazard ratio [aHR] 1.07, 95% CI: 1.02, 1.12), hepatocellular carcinoma (HCC) (aHR 1.23, 95% CI: 1.01, 1.50), coinfection (aHR 1.61, 95% CI: 1.23, 2.09), later notification (2014-2017) (aHR 1.21, 95% CI: 1.16, 1.26) and less likely among females (aHR 0.95, 95% CI: 0.91, 0.99), history of alcohol use disorder (AUD) (aHR 0.77, 95% CI: 0.66, 0.89), HCV coinfection (aHR .62, 95% CI: 0.55, 0.70) and Indigenous peoples (aHR 0.84, 95% CI: 0.71, 0.98). HBV treatment was associated with age ≥45 years (aHR 1.35, 95% CI: 1.24, 1.48), decompensated cirrhosis (aHR 2.07, 95% CI: 1.62, 2.65), HCC (aHR 2.96, 95% CI: 2.35, 3.74), HIV coinfection (aHR 4.27, 95% CI: 3.43, 5.31) and later notification (2014-2017) (aHR 1.37, 95% CI: 1.26, 1.47). HBV treatment was less likely among females (aHR 0.68, 95% CI: 0.63, 0.73) and Indigenous peoples (aHR 0.58, 95% CI: 0.42, 0.80). HBV DNA testing and treatment coverage have increased, but remain sub-optimal among some key populations.

RESUMEN

Abstract: The standard practice of blood borne virus (BBV) follow-up in New South Wales is a passive approach of general-practitioner-led testing. The value of this approach is unknown. We undertook an active contact tracing method with the aims of investigating a potential hepatitis B source, along with accurately measuring the participation rate, to consider the value of this and other follow-up methods for future BBV investigations. Investigation of a newly-acquired hepatitis B infection was undertaken at a dental practice identified as a possible exposure site. To screen for hepatitis B infection among potential source or co-exposed clients, we actively followed up with staff and clients of the practice to request they undertake hepatitis B serology. Eligible staff and clients received up to four phone calls and were provided with a pathology request form by the public health unit (PHU). Access to free serology was offered to people who did not have access to Medicare. Reminder calls were made if serology results were not received by the PHU. As the ordering doctor, the public health physician was responsible for providing results and referring for follow-up care. Of 160 clients, 63 (39%) undertook hepatitis B serology. Of these 63, none were found to have hepatitis B infection. It was estimated the active investigation involved an extra 430 hours of PHU staff time at a cost in Australian dollars of $30,000. Active follow-up allows an accurate participation rate to be documented. Despite intense active follow-up, only 39% of clients undertook testing, bringing into question the yield of the usual approach in which active follow-up of potential mass BBV exposures is not undertaken. While active follow-up is resource intensive, it should be considered where the risks and consequences from the BBV infection are high.

RESUMEN

BACKGROUND: The use of biologics poses a moderate to high risk for hepatitis B virus reactivation (HBVr) in chronic carriers. AIM: To determine the prevalence of HBVr with TNF alpha inhibitors, ustekinumab and vedolizumab METHOD: We followed the MOOSE guidelines and conducted a comprehensive literature search. We conducted a systematic search of EMBASE (Ovid), MEDLINE (Ovid) and PubMed. The studies included patients who were chronic and occult HBV carriers with various rheumatological, dermatological or gastroenterological conditions. We used a random effects model using pooled estimates (prevalence of HBVr with 95% confidence intervals (CI)). RESULTS: We included 29 studies with 1409 patients infected with HBV. The prevalence of HBVr in chronic carriers of HBV was 17.1% (95% CI: 7.0-35.9, n = 5), 16.6% (95% CI: 9.5-27.5%, n = 6), 40.5% (95% CI: 20.3-64.5%, n = 4) and 19.1% (95% CI: 7.3-41.2%, n = 2), respectively, for adalimumab, etanercept, infliximab and ustekinumab. The respective prevalence for reactivation in patients with occult HBV infection was 5.0% (95% CI: 2.8-8.7%, number of studies: n = 18), 2.6% (95% CI: 1.4-4.7%, n = 18), 4.4% (95% CI: 2.2-8.7%, n = 12) and 6.4% (95% CI: 2.2-16.8, n = 5). There were 39 HBVr (26 in chronic HBV and 13 in the occult group) without any hepatic failure or death. In the chronic HBVr group, only three of 24 patients received antiviral prophylaxis. CONCLUSIONS: HBVr prevalence rates differ between the chronic carrier state and the occult carrier state. The uptake of prophylactic antiviral therapy in high-risk groups was low, contrary to clinical practice guidelines.

RESUMEN

Triple elimination is an initiative supporting the elimination of mother-to-child transmission of three diseases - human immunodeficiency virus (HIV) infection, syphilis and hepatitis B. Significant progress towards triple elimination has been made in some regions, but progress has been slow in sub-Saharan Africa, the region with the highest burden of these diseases. The shared features of the three diseases, including their epidemiology, disease interactions and core interventions for tackling them, enable an integrated health-systems approach for elimination of mother-to-child transmission. Current barriers to triple elimination in sub-Saharan Africa include a lack of policies, strategies and resources to support the uptake of well established preventive and treatment interventions. While much can be achieved with existing tools, the development of new products and models of care, as well as a prioritized research agenda, are needed to accelerate progress on triple elimination in sub-Saharan Africa. In this paper we aim to show that health systems working together with communities in sub-Saharan Africa could deliver rapid and sustainable results towards the elimination of mother-to-child transmission of all three diseases. However, stronger political support, expansion of evidence-based interventions and better use of funding streams are needed to improve efficiency and build on the successes in prevention of mother-to-child transmission of HIV. Triple elimination is a strategic opportunity to reduce the morbidity and mortality from HIV infection, syphilis and hepatitis B for mothers and their infants within the context of universal health coverage.


La triple élimination est une initiative visant à soutenir l'éradication de la transmission mère-enfant de trois maladies ­ l'infection au virus de l'immunodéficience humaine (VIH), la syphilis et l'hépatite B. Bien que des avancées considérables aient été observées en ce sens dans certaines régions, les progrès demeurent lents en Afrique subsaharienne, pourtant durement touchée par ces maladies. Les caractéristiques communes aux trois affections, notamment leur épidémiologie, les interactions entre elles et les principales interventions nécessaires à leur prise en charge permettent aux systèmes de santé d'adopter une approche intégrée pour éviter la transmission mère-enfant. Plusieurs obstacles entravent actuellement la triple élimination en Afrique subsaharienne, parmi lesquels l'absence de politiques, de stratégies et de ressources pour garantir la disponibilité de traitements préventifs et curatifs bien établis. Les outils existants offrent déjà de nombreuses solutions; mais pour accélérer la progression de cette triple élimination en Afrique subsaharienne, il est indispensable de développer de nouveaux produits et modèles de soins, ainsi qu'un programme de recherche prioritaire. Dans le présent document, nous voulons montrer que si les systèmes de santé collaborent avec les communautés en Afrique subsaharienne, ils pourront obtenir des résultats rapides et durables en vue d'éradiquer la transmission mère-enfant des trois maladies susmentionnées. Néanmoins, une telle démarche implique un soutien politique massif, l'expansion des interventions fondées sur des données scientifiques, et une meilleure utilisation des sources de financement afin d'améliorer l'efficacité et de s'appuyer sur les réussites en matière de prévention de la transmission du VIH de la mère à l'enfant. La triple élimination représente une occasion stratégique de réduire la morbidité et la mortalité liées à l'infection au VIH, à la syphilis et à l'hépatite B, tant chez les mères que chez les nourrissons, dans un contexte de couverture maladie universelle.


La triple eliminación es una iniciativa que apoya la eliminación de la transmisión maternoinfantil de tres enfermedades: la infección por el virus de la inmunodeficiencia humana (VIH), la sífilis y la hepatitis B. En algunas regiones se han logrado avances significativos hacia la triple eliminación, pero los progresos se han desarrollado con mayor lentitud en el África subsahariana, la región con la mayor carga de estas enfermedades. Las características comunes de las tres enfermedades, como su epidemiología, las interacciones entre ellas y las intervenciones básicas para combatirlas, permiten un enfoque integrado de los sistemas de salud para la eliminación de la transmisión maternoinfantil. Los obstáculos actuales para la triple eliminación en el África subsahariana incluyen la falta de políticas, estrategias y recursos para apoyar la adopción de intervenciones preventivas y de tratamiento bien establecidas. Aunque se puede lograr mucho con las herramientas existentes, se necesita el desarrollo de nuevos productos y modelos de atención, así como una agenda de investigación prioritaria, para acelerar el progreso de la triple eliminación en el África subsahariana. En este documento pretendemos demostrar que los sistemas de salud que trabajan conjuntamente con las comunidades del África subsahariana podrían obtener resultados rápidos y sostenibles hacia la eliminación de la transmisión maternoinfantil de las tres enfermedades. Sin embargo, se necesita un mayor apoyo político, la ampliación de las intervenciones basadas en la evidencia y un mejor uso de los flujos de financiación para mejorar la eficiencia y aprovechar los éxitos en la prevención de la transmisión maternoinfantil del VIH. La triple eliminación es una oportunidad estratégica para reducir la morbilidad y la mortalidad de la infección por el VIH, la sífilis y la hepatitis B para las madres y sus hijos en el contexto de la cobertura sanitaria universal.

RESUMEN

OBJECTIVES: Hepatitis B (HBV) is a common comorbidity among rheumatic patients. The prevalence of HBV infection and the rate of reactivation remain unclear. The literature data suggested a higher risk in chronic than in past infection. Currently, the literature data are mostly focused on anti-TNF and rituximab. This retrospective observational study aimed to analyse the prevalence of HBV infection and the risk of viral reactivation in a population of rheumatic patients undergoing anti-TNF and non-anti-TNF agents. METHODS: We analysed 1216 rheumatic patients, treated with both csDMARDs and bDMARDs between 2006 and 2017. Serologic markers for HBV (HBsAg, anti-HBs, anti-HBc) were performed prior and during biologic treatment. Patients with chronic or resolved infection were monitored every 3 months. RESULTS: The prevalence of HBV in our cohort was 15.7% (chronic infection: 0.4%, resolved infection: 12.6%, anti-HBc positivity alone: 2.6%). 12 (6.2%) out of 191 HBV infected patients experienced a reactivation. All of them showed markers of past infection. One patient experienced HBV reactivation despite lamivudine. Only one patient experienced acute hepatitis, probably due to the interruption of immunosuppressors in anticipation of surgery, not preceded by any HBV prophylactic treatment. CONCLUSIONS: HBV reactivation is a rare event in patients treated with a bDMARD and it can also occur while taking lamivudine, not only in chronic carriers (as per the literature data) but also in inactive ones. Regular screening followed by prompt treatment can prevent symptoms or complications. Due to the risk of hepatitis following the immune reconstitution, an antiviral therapy should be considered in the case of sudden discontinuation of csDMARDs or bDMARD.

RESUMEN

Pregnant women in Vietnam have a high prevalence of hepatitis B virus (HBV) and low prevalence of human immunodeficiency virus (HIV) and syphilis. This study aims to assess the feasibility and benefit of universal testing for HIV, HBV and syphilis in antenatal care (ANC) services. A pilot project was conducted in the Thai Nguyen province of Vietnam between 2012 and 2014. HIV, HBV and syphilis testing were offered to pregnant women. Interventions to eliminate mother-to child-transmission (MTCT) of the three pathogens were provided to infected mothers and their infants. Descriptive analysis was conducted, and the number of infections averted from integrating hepatitis B tests into ANC was estimated. Testing coverage for HIV, HBV and syphilis for the cohort of pregnant women during the pilot project was 98%. Prevalence of HIV, HBV and syphilis infections in this cohort was 0.14%, 7.8%, and 0.03%, respectively. No infant was infected with HIV or syphilis, while HBV infection was diagnosed in 27 infants (13.9%). An estimated 23 mother to child HBV infections were prevented by integrated interventions. The triple prevention of mother-to-child transmission of HIV, HBV and syphilis is feasible. Investment in the expansion of the integrated approach is required to achieve the goal of eliminating MTCT.

RESUMEN

BACKGROUND: The health of people living with HIV/AIDS becomes progressively worse when co-infected with hepatitis B virus (HBV) and hepatitis C virus (HCV), resulting in shortened life span. The modes of transmission of HIV, HBV and HCV are similar. OBJECTIVE: To determine the prevalence of HBV and HCV co-infection in HIV patients. METHOD: This was a retrospective study of serology test results for hepatitis B surface antigen (HBsAg) and antibodies to HCV (anti-HCV) of HIV positive patients registered from 2008-2013 (6years) at the University of Nigeria Teaching Hospital. Adult patients with confirmed HIV seropositivity were included. Ethical approval was obtained and confidentiality of the patient information was maintained. Laboratory records were reviewed to obtain HBsAg, anti-HCV, and CD4 T-lymphocyte results. Prevalence was determined by the number of positive results over total number of patients tested. Chi-square test was used to determine relationships and p<0.05 was considered to be statistically significant. RESULTS: 4663 HIV patient records were included comprising 3024 (65%) females and 1639 (35%) males. Serology results showed 365/4663 (7.8%) tested HBsAg-positive only; 219/4663 (4.7%) tested anti-HCV-positive only; and 27/4663 (0.58%) tested both HBsAg and anti-HCV-positive. Correlation of age and sex were statistically significant with HBV and HCV (p<0.05) but not CD4 count (p>0.05). CONCLUSION: HBV co-infection was more prevalent than HCV, and triple infection was also observed. Screening for these viral infections in the HIV population is necessary for early identification to enable appropriate, holistic management of these patients.

RESUMEN

OBJECTIVES: This study describes the burden of the hepatitis B, C and HIV co-infections and assesses associated risk factors. SETTING: This analysis used data from a viral hepatitis screening campaign conducted in six districts in Rwanda from April to May 2019. Ten health centres per district were selected according to population size and distance. PARTICIPANTS: The campaign collected information from 156 499 participants (51 496 males and 104 953 females) on sociodemographic, clinical and behavioural characteristics. People who were not Rwandan by nationality or under 15 years old were excluded. PRIMARY AND SECONDARY OUTCOMES: The outcomes of interest included chronic hepatitis C virus (HCV) infection, chronic hepatitis B virus (HBV) infection, HIV infection, co-infection HIV/HBV, co-infection HIV/HCV, co-infection HBV/HCV and co-infection HCV/HBV/HIV. Multivariable logistic regressions were used to assess factors associated with HBV, HCV and HIV, mono and co-infections. RESULTS: Of 156 499 individuals screened, 3465 (2.2%) were hepatitis B surface antigen positive and 83% (2872/3465) of them had detectable HBV desoxy-nucleic acid (HBV DNA). A total of 4382 (2.8%) individuals were positive for antibody-HCV (anti-HCV) and 3163 (72.2%) had detectable HCV ribo-nucleic acid (RNA). Overall, 36 (0.02%) had HBV/HCV co-infection, 153 (0.1%) HBV/HIV co-infection, 238 (0.15%) HCV/HIV co-infection and 3 (0.002%) had triple infection. Scarification or receiving an operation from traditional healer was associated with all infections. Healthcare risk factors-history of surgery or transfusion-were associated with higher likelihood of HIV infection with OR 1.42 (95% CI 1.21 to 1.66) and OR 1.48 (1.29 to 1.70), respectively, while history of physical traumatic assault was associated with a higher likelihood of HIV and HBV/HIV co-infections with OR 1.69 (95% CI 1.51 to 1.88) and OR 1.82 (1.08 to 3.05), respectively. CONCLUSIONS: Overall, mono-infections were common and there were differences in significant risk factors associated with various infections. These findings highlight the magnitude of co-infections and differences in underlying risk factors that are important for designing prevention and care programmes.

RESUMEN

Chronic hepatitis B infection (HBV) disproportionately affects African Immigrant (AI) communities in the U.S., with a reported infection rate of 15%. HBV screening rates within these communities are low. This study sought to better understand the socio-cultural determinants associated with low HBV screening among AI communities and identify potential strategies to help inform the development of effective HBV education and screening interventions. Seventeen in-depth interviews were conducted with community health experts working in AI communities throughout the U.S. Interviews explored the potential impact of culture, perception of health, awareness of HBV, religious practices, current screening practice, provider relationship, and behaviors towards general prevention. Interview data were analyzed using thematic analysis. Religious preferences and cultural norms affect health care access, perceptions towards prevention, awareness of HBV, and contribute to myths and stigma within this population. Participants reported a lack of HBV knowledge and awareness and barriers to health care access including, cost, language, racism, understanding of Western Medicine, and usage of traditional medicine. This study elucidates the role of religious and cultural beliefs as barriers to HBV screening and care. Results can contribute to public health efforts to increase awareness, screening and vaccination efforts within AI communities.

RESUMEN

Sorafenib is of proven efficacy in treating patients of hepatocellular carcinoma (HCC). Our study was aimed to determine the factors influence the sorafenib efficacy.We evaluated data of HCC patients receiving sorafenib from June 2012 to October 2016. All HCC cases were of the Barcelona Clinic Liver Cancer (BCLC) classification stage C. The exclusion criteria: those of BCLC classification stage A or B, with the absence or co-infection of hepatitis B (HBV) and hepatitis C (HCV). The presence of HBV, HCV, macoscopic vascular invasion (MVI) or extrahepatic spread (EHS) was recorded for each patient. Time-to-progression (TTP) and overall survival (OS) were analyzed.Among a total of 90 HCC patients, 48 (53.3%) had HBV infection, 42 (46.7%) had HCV infection, 51 (56.7%) had MVI, and 39 (43.3%) had EHS. Patients with HCV infection showed better TTP and OS than those with HBV infection. Patients with EHS had a longer TTP and OS than those with MVI. For patients with HBV infection, those with EHS had a longer TTP (mean 4.60 vs 2.64 months, P = .002) and OS (mean 6.65 vs 4.53 months, P = .045) compared to those with MVI. Among those with MVI, patients with HBV infection had a poorer TTP (mean 2.64 vs 4.74 months, P = .019) and shorter OS (mean 4.53 vs 7.00 months, P = .059) compared to those with HCV infection.HCC patients with HCV infection or with the presence of EHS showed better sorafenib efficacy.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Asari Radix (Xixin, Asarum heterotropoides Fr. Schmidt var. mandshuricum Kitag., Asarum sieboldii Miq., or Asarum sieboldii Miq. var. seoulense Nakai, Asarum spp.) is the only herbal medicine containing aristolochic acid that can be used in medical practice. However, scientific evidence regarding its safe use in relation to hepatocellular carcinoma (HCC) is lacking. AIM OF THE STUDY: The aim of this study was to use post-marketing surveillance to provide a scientific understanding of the relationship between Asari Radix and the development of HCC and suggest the maximum allowable amount of Asari Radix. MATERIALS AND METHODS: A retrospective, population-based cohort study was conducted, with patients randomly selected and divided into three cohorts: a non-hepatitis B virus (HBV)/hepatitis C virus (HCV) cohort, a HBV cohort, and a HCV cohort. Data were retrieved from the National Health Insurance Research Database of Taiwan from January 1, 1997 to December 31, 2013. The study period covered the initial 10 years of exposure to persistent HBV or HCV, followed by exposure to Asari Radix for an additional 8 years. RESULTS: After propensity score matching, 106,942, 3818, and 928 patients were included in the non-HBV/HCV, HBV, and HCV cohorts, respectively. These cohorts included 75, 50, and 42 HCCs and 1,564,943, 30,956, and 6938 person-years, respectively. All hazard ratios of exposure to 1-30 g, 31-60 g, 61-100 g, and 101-200 g of Asari Radix in these three cohorts showed negative associations between Asari Radix exposure and HCC development. Furthermore, the three cohorts demonstrated that exposure to under 200 g of Asari Radix was safe. CONCLUSIONS: Post-marketing surveillance showed that Asari Radix has no relationship with HCC development at an intake of under 200 g. The study is persuasive in furthering our knowledge of the maximum allowable amount of Asari Radix.

RESUMEN

OBJECTIVES: The preferred modality for renal replacement therapy is renal transplantation. Marked improvements in early graft survival and long-term graft function have made renal transplantation a more cost-effective alternative to dialysis. The presence of liver disease in the posttransplant period adversely affects graft function and survival. Determining the cause of deranged liver function tests can be helpful in treating the underlying cause, leading to improved graft survival and overall quality of life in patients after renal transplant. Here, we determined the frequency of hepatotropic viral infections leading to deranged liver function tests in renal transplant recipients. MATERIALS AND METHODS: Our study included 132 patients with deranged liver function tests who had undergone renal transplant within the past 6 months. Reactivity and nonreactivity of hepatotropic viruses leading to deranged liver function tests were recorded. RESULTS: Average age of patients was 37.17 ± 8.75 years. There were 84 male (63.64%) and 48 female (36.36%) patients. Rates of hepatitis C virus antibodies and hepatitis B surface antigen were 62.88% (83/132) and 37.12% (49/132), respectively, whereas no patients had hepatitis E virus immunoglobulin M antibodies or hepatitis A virus immunoglobulin M antibodies. CONCLUSIONS: Among the hepatotropic viral infections leading to deranged liver function tests in renal transplant recipients, hepatitis B virus accounted for a small fraction. In contrast, hepatitis C virus was highly prevalent in transplant recipients who developed deranged liver function tests. Renal transplant recipients with hepatic viral infections have worse patient and allograft survival after transplant compared with noninfected renal transplant recipients. We recommend that transplant candidates be screened for hepatitis B and C virus infection, thus allowing increased graft survival and improved quality of life in renal transplant recipients.

RESUMEN

OBJECTIVES: To estimate hepatitis B virus (HBV) seroprevalence from natural infection or vaccination in 10-25-year-olds in Mexico, using the 2012 National Health and Nutrition Survey (ENSANUT). METHODS: Randomly selected serum samples (1,581) from adolescents and young adults, representative of 38,924,584 Mexicans, were analyzed to detect hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs) and hepatitis B core antibody (anti-HBc). Weighted HBV seroprevalence in the Mexican population and association with sociodemographic variables were calculated. RESULTS: Overall weighted seroprevalence from natural infection (positive for anti-HBs and anti-HBc) was 0.23% (95% confidence interval [95% CI] 0.10-0.52). No HBsAg was detected, indicating no acute or chronic infection. Vaccine-derived immunity (positive ≥ 10.0 mIU/ml for anti-HBs and negative to anti-HBc) was 44.7% (95% CI: 40.2-49.4) overall; lower in persons aged 20-25 years (40.83%) than in persons aged 10-19 years (47.7%). Among the population analyzed, 54.2% (95% CI: 49.6-58.8) were seronegative to HBV (negative for all three markers) and no sociodemographic risk factors were identified. CONCLUSIONS: HBV seroprevalence from natural infection was low. Vaccination-induced immunity was higher among Mexican adolescents than young adults, possibly due to vaccination policies since 1999.

RESUMEN

This Review presents current epidemiological trends of the most common liver diseases in Asia-Pacific countries. Hepatitis B virus (HBV) remains the primary cause of cirrhosis; despite declining prevalence in most Asian nations, this virus still poses a severe threat in some territories and regions. Mortality resulting from HBV infection is declining as a result of preventive measures and antiviral treatments. The epidemiological transition of hepatitis C virus (HCV) infection has varied in the region in the past few decades, but the medical burden of infection and the prevalence of its related cancers are increasing. The lack of licensed HCV vaccines highlights the need for novel treatment strategies. The prevalence of nonalcoholic fatty liver disease (NAFLD) has risen in the past decade, mostly owing to increasingly urbanized lifestyles and dietary changes. Alternative herbal medicine and dietary supplements are major causes of drug-induced liver injury (DILI) in some countries. Complications arising from these chronic liver diseases, including cirrhosis and liver cancer, are therefore emerging threats in the Asia-Pacific region. Key strategies to control these liver diseases include monitoring of at-risk populations, implementation of national guidelines and increasing public and physician awareness, in concert with improving access to health care.

RESUMEN

PURPOSE: Biologic therapy in psoriatic patients with multiple comorbidities is challenging due to worsening of associated diseases and possible side effects of concomitant medications. MATERIALS AND METHODS: We describe three patients with multiple comorbidities documenting successful treatment of psoriasis with secukinumab following failure of multiple conventional and biologic DMARDs. RESULTS: The first case is an obese 59-year-old woman (HBV + with latent tuberculosis) with arterial hypertension and 12-year history of breast cancer. The second is a 45-year-old obese man (HCV + with occult HBV infection on therapy with multiple antipsychotics and taking methadone for opioid dependence), while the last is a 39-year-old man with severe obesity, non-alcoholic hepatosteatosis, and NYHA class II heart failure. All three patients had undergone previous conventional (methotrexate, cyclosporine, retinoids, and phototherapy) and multiple biologic treatments (one or more of the following: adalimumab, ustekinumab, etanercept, infliximab originator, and biosimilar) that were discontinued for inefficacy and/or adverse effects. All patients underwent therapy with secukinumab, which was associated with sustained clinical benefits and no clinically relevant safety findings. CONCLUSIONS: The present three cases add further evidence that secukinumab is effective and well tolerated in difficult to treat psoriatic patients with multiple comorbidities, namely HBV, latent TBC infection, and hepatic impairment.

RESUMEN

We evaluated uptake and diagnostic outcomes of voluntary hepatitis B (HBV) and C virus (HCV) screening offered during routine tuberculosis entry screening to migrants in Gelderland and Amsterdam, the Netherlands, between 2013 and 2015. In Amsterdam, HIV screening was also offered. Overall, 54% (461/859) accepted screening. Prevalence of chronic HBV infection (HBsAg-positive) and HCV exposure (anti-HCV-positive) in Gelderland was 4.48% (9/201; 95% confidence interval (CI): 2.37-8.29) and 0.99% (2/203; 95% CI: 0.27-3.52), respectively, all infections were newly diagnosed. Prevalence of chronic HBV infection, HCV exposure and chronic HCV infection (HCV RNA-positive) in Amsterdam was 0.39% (1/256; 95% CI: 0.07-2.18), 1.17% (3/256; 95% CI: 0.40-3.39) and 0.39% (1/256; 95% CI: 0.07-2.18), respectively, with all chronic HBV/HCV infections previously diagnosed. No HIV infections were found. In univariate analyses, newly diagnosed chronic HBV infection was more likely in participants migrating for reasons other than work or study (4.35% vs 0.83%; odds ratio (OR) = 5.45; 95% CI: 1.12-26.60) and was less likely in participants in Amsterdam than Gelderland (0.00% vs 4.48%; OR = 0.04; 95% CI: 0.00-0.69). Regional differences in HBV prevalence might be explained by differences in the populations entering compulsory tuberculosis screening. Prescreening selection of migrants based on risk factors merits further exploration.

RESUMEN

BACKGROUND: Veterans are disproportionately affected by human immunodeficiency virus (HIV), hepatitis C virus (HCV), and hepatitis B virus (HBV). Homeless veterans are at particularly high risk for HIV, HCV, and HBV due to a variety of overlapping risk factors, including high rates of mental health disorders and substance use disorders. The prevalence of HIV, HCV, and HBV among homeless veterans nationally is currently unknown. This study describes national testing rates and prevalence of HIV, HCV, and HBV among homeless veterans. METHODS: Using data from the Department of Veterans Affairs (VA) Corporate Warehouse Data from 2015, we evaluated HIV, HCV, and HBV laboratory testing and infection confirmation rates and diagnoses on the Problem List for nonhomeless veterans and for veterans utilizing homeless services in 2015. RESULTS: Among 242740 homeless veterans in VA care in 2015, HIV, HCV, and HBV testing occurred in 63.8% (n = 154812), 78.1% (n = 189508), and 52.8% (n = 128262), respectively. The HIV population prevalence was 1.52% (3684/242740) among homeless veterans, compared with 0.44% (23797/5424685) among nonhomeless veterans. The HCV population prevalence among homeless veterans was 12.1% (29311/242740), compared with 2.7% (148079/5424685) among nonhomeless veterans, while the HBV population prevalence was 0.99% (2395/242740) for homeless veterans and 0.40% (21611/5424685) among nonhomeless veterans. CONCLUSIONS: To our knowledge this work represents the most comprehensive tested prevalence and population prevalence estimates of HIV, HCV, and HBV among homeless veterans nationally. The data demonstrate high prevalence of HIV, HCV, and HBV among homeless veterans, and reinforce the need for integrated healthcare services along with homeless programming.

RESUMEN

Hepatitis B virus (HBV) infection is a critical global health problem. The World Health Organization (WHO) has recently developed a global elimination strategy for HBV infection. Increasing access to screening, liver assessment, and antiviral treatment are crucial steps in achieving this goal. Little is known, however, about obstacles to linkage to care in low- and middle-income countries. Using a grounded theory approach, this qualitative study sought to characterize the diagnostic itineraries of people with chronic HBV infection in Burkina Faso, a west African country with high HBV prevalence, to identify barriers to linkage from screening to specialist care with hepatic assessment (alanine transaminase and hepatitis B e antigen or HBV DNA). We conducted 80 semistructured interviews with chronically infected people, their families, medical personnel, and traditional practitioners, and participant observation of HBV diagnostic announcements and consultations. Of 30 individuals diagnosed with chronic viral hepatitis, 18 inadvertently discovered their status through blood screening and 12 actively sought diagnosis for their symptoms. Only a quarter (8/30) were linked to care. Barriers included: 1) patients' ability to pay for testing and treatment; 2) a formal health system lacking trained personnel, diagnostic infrastructures, and other resources; 3) patients' familial and social networks that discouraged access to testing and HBV knowledge; 4) a well-developed demand for and provisioning of traditional medicine for hepatitis; and 5) a weak global politics around HBV. More training for medical personnel would improve linkage to care in sub-Saharan Africa. Developing effective communications between medical workers and patients should be a major priority in this elimination strategy.
