Assessment of Practices Regarding Hepatitis B Infection and Its Prevention among Undergraduate Students of a Government Medical College in Agra, Uttar Pradesh, India

There is limited data on the effect of antiviral therapies on clinical outcomes in HIV and hepatitis B virus (HBV)-infected individuals in sub-Saharan Africa. Single center, prospective longitudinal cohort study at Management and Development for Health supported HIV Care and Treatment clinics in Dar es Salaam, Tanzania. Between April 2014 and December 2015, HIV-infected, HBV-infected and HIV/HBV-coinfected, treatment naïve, Tanzanian adults more than 18 years of age were eligible for enrollment and followed for 10-18 months after initiating antivirals. All HIV-infected and HIV/HBV-coinfected participants received tenofovir, lamivudine and efavirenz; HBV-infected participants received lamivudine. Multivariate regression models were constructed to identify factors associated with mortality in HIV-infected and HIV/HBV-coinfected participants. A total of 265 HIV-infected, 165 HBV-infected and 64 HIV/HBV-coinfected participants were analyzed. At baseline, HBV-infected participants were younger and had a higher BMI than HIV-infected and HIV/HBV-coinfected participants. After a median of 371 (interquartile range 50) days on treatment, there were 40 deaths. Mortality was significantly higher among HIV/HBV-coinfected participants compared with HIV and HBV-infected participants [HIV/HBV-coinfected 12 of 64 (19%) vs. HIV-infected 26 of 265 (10%) and HBV-infected two of 265 (1%), P < 0.01]. High baseline HIV RNA and low hemoglobin levels, but not HBV coinfection were independently associated with early mortality in multivariate analyses of HIV-infected participants. High rates of early mortality were observed after treatment initiation in HIV/HBV-coinfected individuals compared with participants with HIV or HBV alone, despite robust aspartate aminotransferase to platelet ratio index declines and high rates of virologic suppression. HIV rather than HBV-related factors are more important contributors to mortality in these individuals.

Pre-S Deletion and Complex Mutations of Hepatitis B Virus Related to Advanced Liver Disease in HBeAg-Negative Patients

Lamivudine Plus Low-Dose Hepatitis B Immunoglobulin to Prevent Recurrent Hepatitis B Following Liver Transplantation

Hepatitis B virus (HBV) and hepatitis C virus (HCV) infection substantially cause series of liver diseases worldwide. Because these two viruses share the modes of transmission, HBV HCV co-infection is common with approximately 7-20 million people affected globally. Hemodialysis individuals are at risk of HBV and HCV infections. The prevalence rates of coinfection with HBV and HCV in Hemodialysis patients have been variable worldwide depending on the geographic regions, and the type of exposure. This study aimed to exam-ine HBV and HCV coinfection and determine the shared and significant fac-tors in the coinfection in Hemodialysis patients. This descriptive, cross-sectional study was carried out on 237 Hemodialysis patients including 153 males and 84 females in Lucknow, Uttar Pradesh, to survey coinfection with HBV and HCV using ELISA. The retrospective demographic data of the sub-jects was collected and the patient’s serums were analyzed by ELISA. The collected data was analyzed with Instat (Graphpad) software. Fisher's exact test with 5% error intervals was used to measure the correlation of variables and infection rates. The results of the study indicated that the prevalence of hepatitis B &amp; C virus in hemodialysis patients was 9.70% (n=23), out of which 1 (0.42%) was suffering with HBV &amp; HCV co-infection while 6 were only HBV positive and 16 were only HCV positive. There is very low prevalence of Hep-atitis C Virus and Hepatitis B Virus coinfection in hemodialysis patients in this region.

Healthcare workers (HCWs) are at an increased risk of contracting and transmitting the hepatitis B virus (HBV). Vaccination coverage against HBV a cost- effective prevention, remains low among HCWs in some settings. To determine the prevalence of HBV infection, vaccination coverage, and immune responses to HBV vaccine among HCWs at Muhimbili National Hospital (MNH) in Dar es Salaam. This cross-sectional study used a proportional probability systematic sampling to recruit HCWs from MNH in Dar es Salaam. A structured questionnaire was used to collect social demographic characteristics, infection prevention and control practices, HBV vaccination status and reasons for not vaccinating. Five mLs of a peripheral venous sample was obtained from each participant, the sample was used to test for HBV surface antigen, HBV surface antibody and HBV core antibody for assessing for infection, and vaccine immunity respectively. A Robust Poisson Regression analysis was used to assess factors associated with not vaccinating. The prevalence of HBV infection was 5 (1.2%) among the 415 recruited HCWs. Only 192 (46.3%) HCWs were vaccinated and 169 (96%) had protective immunity against HBV infection among 176 participants who had received at least two vaccine doses. HCWs who were laboratory scientist aPR = 2.01, 95% CI (1.35-3.00) and had < 10 years of employment aPR = 1.62, 95% CI (1.04-2.50) were unlikely to vaccinate against HBV. Vaccine unavailability 114 (51.1%), hesitancy 42 (18.8%), time constraints 41 (18.4%) and financial constraints 26 (11.7%) were factors associated with not vaccinating. Vaccine coverage against HBV among HCWs at MNH is alarmingly low. Vaccine access, subsidizing cost, protecting time for vaccination could improve vaccination uptake. Qualitative studies are needed to assess for reasons for vaccine hesitancy among HCWs.

MMWR: CDC Guidance for Evaluating Healthcare Personnel for Hepatitis B Virus Protection and for Administering Postexposure Management

BackgroundIndia is home to one in 14 of all chronic hepatitis B virus (HBV) cases, meaning that it is important to develop HBV interventions that are applicable in the Indian context. Vaccination is the foremost tool for interrupting the HBV infection cycle. HBV vaccination was not included in India’s government-sponsored expanded immunisation program until 2011, and many children born earlier remain unvaccinated. This study sought to observe the impact of the HOPE Initiative’s school-based intervention to increase vaccination coverage by increasing HBV awareness among students in Lucknow, Uttar Pradesh.MethodsAt 430 schools in the administrative areas within and surrounding Lucknow, students viewed an educational documentary film on HBV and completed two questionnaires, one immediately before the screening and the other six weeks later. Both questionnaires asked the same 14 questions, which were organized into five domains: knowledge of the magnitude of the problem of HBV; knowledge of modes of HBV transmission; knowledge of consequences of HBV infection; awareness of HBV; and attitudes regarding HBV. The baseline questionnaire also asked students whether they had been vaccinated against HBV. At two-year follow-up, researchers measured vaccination levels at a subset of 30 intervention schools and six non-intervention schools to further assess the impact of the intervention.ResultsBaseline questionnaires were completed by 11,250 students, and post-intervention questionnaires, by 9698 students. Scores for knowledge about the magnitude of the HBV problem improved from 41% at baseline to 74% at follow-up, and scores for knowledge about modes of transmission, from 38% to 75% (p < 0.05 for both). The baseline HBV vaccination level among students receiving the intervention was 21%. Two years after the intervention, 45% of students (N = 4284) reported being vaccinated at intervention schools compared to 22% (N = 1264) at non-intervention schools.ConclusionsThe observed increases in HBV awareness, knowledge and vaccination levels in this study indicate that school-based interventions can be used to achieve higher vaccination coverage among Indian children. The documentary film was found to be an affordable tool for reaching large audiences. More studies are needed to validate the impact of this intervention and to explore its applicability to other social causes.

Background Mother-to-child transmission (MTCT) of the hepatitis B virus (HBV) is significant, as most infants infected at birth go on to develop chronic hepatitis B. Vaccination and antiviral treatment during pregnancy could primarily prevent vertical transmission. Therefore, the purpose of this study is to assess pregnant Jordanian females' knowledge, attitude, and practices (KAP) toward HBV. In addition, to explore the relationship between the level of KAP toward HBV infection and its predictors. Methods Our cross-sectional study was conducted among pregnant women in Jordan. We enrolled 621 participants between January and April 2023. Our survey was derived from a previously validated tool that was used to investigate a similar aim as our study. The survey was done via Google Forms (Google LLC, Mountain View, California, United States)and it contained questions divided into four main sections: participants' demographics, knowledge section, attitudes section, and practices section. Results The majority of participants have neither a personal nor family history of HBV, and only 91 (14.7%) of the participants had a medical degree. The overall knowledge, attitude, and practice (KAP) scores were low, as only 176 (28.3%), 315 (50.7%), and 244 (39.3%) of participants achieved high levels of knowledge, attitude, and practice scores, respectively. A significant association was found between knowledge level, practice assessment, and the following variables: age, educational level, job, study field, history of HBV in the family, and source of knowledge. Regarding attitude, a significant association was found with the job, study field, and source of knowledge. Conclusion This study found that pregnant women in Jordan had a low level of awareness of HBV infection. Thus, more efforts should be made to raise awareness about HBV among high-risk groups, especially pregnant women.

Epidemiology of hepatitis B in Europe and worldwide.

Despite widespread concern and knowledge about the need for infection prevention and control in health care, it is clear that adherence to strict infection control procedures is not always at an optimal level (El-Masri and Oldfield, 2012). Hospital Acquired Infection (HAI) may occur when these standards break down, and HAI is a commonly discussed media topic (Bates, 2012). Alarmingly, a recent outbreak of Hepatitis C in the USA, resulting from inappropriate interference by health staff with equipment (needles) (Ramer, 2012) reminds us that even when vigilant approaches are used to combat the spread of infection, the potential for contamination from blood-borne infections remains a real possibility. Blood-borne viral infections include human immunodeficiency virus (HIV), Hepatitis C virus (HCV) and Hepatitis B virus (HBV). Taking precautions alone is not sufficient; staffs need to be knowledgeable in the disease and spread of disease. It is important to note that the risk of disease spread is to both staff and patients, although most staffs are vaccinated to prevent HBV (DoHC, 2005). While discussion papers and research studies on the topics of blood-borne diseases such as HCV, HBV and HIV/Aids are reduced in number compared with the 1980s and 1990s, current literature appears to indicate that knowledge deficits exist among nurses with regard to both HCV (Frazer et al., 2011) and HIV/Aids (Delobelle et al., 2009), and education and training specifically on these topics seems to be inconsistent and in some cases minimal (Delobelle et al., 2009; Frazer et al., 2011). This editorial discusses how blood-borne viruses (BBVs) can be best prevented in the health care setting in order to highlight the need for ongoing vigilance. An increased incidence of HBV and HCV transmission in the USA is associated with unsafe medical practices (Moore et al., 2011) particularly in those persons aged over 55 (Perz et al., 2012). These two viruses are the most prevalent in the USA with an estimated 1·4 million persons chronically infected with HBV and 3·2 million persons chronically infected with HCV (Weinbaum et al., 2008). A BBV is transmitted through contact with blood or body fluids typically through sexual or household contact, intravenous drug use or other parenteral exposures (Wise et al., 2012). Within health care settings, BBV transmission occurs through direct percutaneous inoculation of infected blood via needlestick or sharps injury or by blood splashed onto broken skin or mucous membranes (Stein et al., 2003). Health care workers (HCWs) undertaking exposure-prone procedures (EPPs) are also at risk of contracting BBVs (DoHC, 2005). The average risk of occupational HIV transmissions associated with percutaneous exposure to blood is 0·32% (approximately 1 infection in 325 documented exposures to blood from HIV-infected individuals) and for mucosal exposures it is 0·03% (approximately 1 infection for each 3300) (Henderson, 2012). The risk of occupational HBV infection following a parenteral exposure from an HBV-infected source patient with circulating e antigen is between 19% and 37% (Werner and Grady, 1982). The risk of occupational infection with HCV following parenteral exposure to blood from HCV-infected source patient is estimated at 1·9% per exposure (Henderson, 2003). In 1985, following an HIV epidemic, the Centre's for Disease Control (CDC) developed recommendations for prevention of HIV transmission in health care settings known as universal precautions (UP) (CDC, 1987). Blood was identified as the single most important source of HIV and HBV (Garner and Hospital Infection Control Practices Advisory Committee, 1996). As it is impossible to identify all patients that are sero-positive to HIV, HBV or HCV, UP dictates that all patients should be regarded as a potential biohazard (Garner and Hospital Infection Control Practices Advisory Committee, 1996; DoH UK, 1998). However, body substance isolation precautions (aimed at regarding all moist and body substances as potentially infectious) are familiar to all nurses as they are in use since 1987 (Garner and Hospital Infection Control Practices Advisory Committee, 1996). CDC then produced a two tier isolation precaution system known as standard precautions (SP) (Garner and Hospital Infection Control Practices Advisory Committee, 1996; Siegel et al., 2007). The first tier is designed for the care of all patients in hospitals, regardless of diagnosis or presumed infection status. The second tier, ‘Transmission-Based Precautions’ is for patients known or suspected to be infected by a transmissible infection (Garner and Hospital Infection Control Practices Advisory Committee, 1996; Siegel et al., 2007). SP principles include hand hygiene, patient isolation, personal protective equipment (PPE), personal and environmental hygiene, appropriate management of linen and health care waste, including sharps. Hand hygiene is the most important principle to prevent the spread of infection (WHO, 2009; HPSC, 2011a, 2011b). Hand hygiene includes hand-washing with soap (or antimicrobial soap) and water or alcohol gel. It also prescribes that cuts and abrasions are covered with waterproof dressings (WHO, 2009; HPSC, 2011a, 2011b). Stein et al. (2003) illustrated that while doctors understood the importance of hand hygiene, only 7 in 10 followed it frequently in practice. Patients with a BBV should be risk assessed to determine the type of isolation required. Patients that are actively bleeding or with large open wounds require contact precaution isolation (Siegel et al., 2007). Signs alerting staff to the type of isolation should be placed on the door and appropriate PPE should be available. PPE such as gloves and/or apron are required in the event of exposure to blood or body fluids (Siegel et al., 2007). Seventy-one percent of doctors do not wear gloves when taking blood despite 83% believing it important (Stein et al., 2003). Masks are not usually necessary unless to protect from other active infectious diseases, e.g. a patient with pulmonary tuberculosis. The environment should be cleaned daily with detergent and water and disinfected in the event of blood or body fluid spill. Blood spills require appropriate action, e.g. use of spill kits with PPE; appropriate disinfection agents to kill any viruses present; disposable scoops and yellow health care waste bags. Blood spills must be managed and decontaminated to prevent persons becoming contaminated (Siegel et al., 2007). The environment and instruments can also become contaminated with blood. This can lead to infection outbreaks such as the case of podiatry instruments that were the source of an outbreak of HBV in a long-term care facility (Wise et al., 2012). Health care waste is divided into health care risk waste and health care non-risk waste (DoHC, 2010). Health care risk waste includes any item contaminated with blood. Blood-stained products must be appropriately discarded in the yellow health care risk waste stream. If blood is in liquid form, a yellow rigid spill-proof container is used. Needles and sharps should be discarded in designated sharps containers (DoHC, 2010). Needlestick injuries (NSI) or sharps injuries must be managed appropriately. US surveillance indicates more than 380 000 parenteral annual exposures to blood. This equates to nearly 1 in 10 US HCWs receiving a needlestick exposure annually (Panlilio et al., 2004). Alarmingly, Delobelle et al.'s figure (as reported by the nurses themselves in response to survey) was as high as 7 of 10. The discrepancies in figures could be due to underreporting of NSI, which does occur in health care, and it is believed that doctors are least likely to report NSI (Stein et al., 2003). It is very important for nurses in critical care who are exposed to an NSI to perform first-aid to the injury and report to their supervisor and Occupational Health /Emergency Department. Occupational exposure should be assessed and treated accordingly, for example by immunization, hepatitis B immune globulin and post exposure chemoprophylaxis for exposure to HIV. There are also emotional effects of such exposure such as stress (Henderson, 2012) which need to be dealt with as well as financial implications. The cost of management of occupational exposures to blood and body fluids can vary from $71 to $4838 per exposure (O'Malley et al., 2007). An EU directive (2010/32/EU) was published in May 2010 (Council Directive, 2010). Its objective is to achieve the safest possible work environment for HCWs through the prevention of sharps injuries. All health care organizations must comply with this directive, which becomes legally binding on 11 May 2013 (European Biosafety Network, 2010). Perz et al. (2012) determined that unsafe injection practices account for a proportion of HBV acquisitions in health care settings (e.g. use of multi-dose vials; incorrect administration of injections resulting in microscopic quantities of blood contaminating the environment). An outbreak of HCV was identified in an outpatient's clinic where myocardial perfusion imaging was undertaken (Moore et al., 2011). It was determined that a nuclear medicine technologist routinely drew flushes of saline solution from multi-dose vials using the same needle and syringe as had previously been used to administer radiopharmaceutical doses (Moore et al., 2011). In addition, Fischer et al. (2010) highlighted HCV transmission resulting from contamination of single-use medication vials used on multiple patients during anaesthesia administration. As a consequence, more than 50 000 persons required follow-up by Public Health. This investigation highlighted breaches in aseptic technique and deficiencies in oversight within outpatient settings. BBV outbreaks have also been caused through blood glucose monitoring. Five instances of HBV in UK care homes resulted from poor infection control practice in blood glucose testing (Duffell et al., 2011). HBV outbreak was also noted in a long-stay facility where blood glucose monitoring devices were not decontaminated between patients. This resulted in HBV transmission to at least six residents (Schaffzin et al., 2012). HCV has also been transmitted by shared spring-triggered capillary blood glucose monitoring (Desenclos et al., 2001). Recently, Perz et al. (2012) identified haemodialysis as another risk factor in blood-borne pathogen transmission, while several documented cases of patient-to-patient HCV transmission via colonoscope exist (González-Candelas et al., 2010). Most occupational exposures occur on wards (36%), operating theatres account for 17% of incidents (HPA, 2008). Once a BBV is diagnosed in a health care setting, a local investigation is necessary to determine whether the infection is considered as nosocomial. Under the Infectious Disease Regulations (1981) the Department of Public Health must be notified of HBV and HCV infections. A patient notification exercise (PNE) is undertaken using ‘Guidance on the management and investigation of potential exposure to BBVs in health care setting’ (DoHC, 2005). Surveillance is a key performance indicator in the management of HCAI. Early identification of outbreaks and active surveillance of occupational exposures is also necessary. Occupational exposures include percutaneous exposures, where skin has been broken by a needle or sharp, human scratches or bites and mucotaneous exposures (HPA, 2008). Between 1997 and 2008, 3773 occupational exposures to blood or other high risk body fluids were reported to the Health Protection Agency in the UK (HPA, 2008). Feedback from surveillance and good communication informs staff of risks and of appropriate precautions. A study by Donohue et al. (2012) included recommendations such as enhanced surveillance of BBV notifications; sufficient laboratory resources; improved hospital information systems; the establishment of a national register of possible incidents of BBV transmission and that findings of investigations should be published. These would contribute to the further prevention of BBV within the health care setting. Transmission of BBVs in health care settings was believed to occur most frequently during EPPs; however, there is growing evidence of patient-to-patient transmission via other routes (Donohue et al., 2012) including deficient policies and procedures, improper hand hygiene, preparation of medication in blood processing areas, blood glucose monitoring, common-use saline bags, reuse of syringes, reuse of single-dose vials and use of multi-dose drug vials (Kermode et al., 2005; Greeley et al., 2011; Donohue et al., 2012). Perz et al. (2012) concluded that health care exposures may represent an important source of new HBV and HCV infections among older adults especially in ambulatory care settings through reduced oversight and fewer infection control resources. Strategies associated with injury prevention include avoidance of unnecessary needle use; unnecessary insertion of intravenous catheters; use of needleless or protected needle infusion systems and use of safer needles (Henderson, 2012). Health care associated infections and outbreaks of BBV have occurred in health care settings therefore it is necessary that a good infection control programme is in place (HIQA, 2009). Hand hygiene and adherence to SP are important in the prevention of spread of infections (SARI, 2005; Siegel et al., 2007). Reducing occupational exposure will reduce occupational infections with BBVs (Henderson, 2012). Education of staff is essential. Stein et al. (2003) observed the attitudes and compliance of medical staff to UP and recorded reasons for non-compliance. It concluded that while 86% of nurse's s attested to UP compliance, only 41% of doctors did. Education, monitoring, sufficient resources and disciplinary action for poor compliance are all necessary to improve infection control in hospitals (Stein et al., 2003). Although safety-engineered devices have been designed to cover sharps and eliminate all ‘after-use’ injuries, NSI still occur if these devices are used incorrectly. Thorough training and monitoring of the correct use of these safety devices is required (Perry et al., 2004). This training, together with regular education on blood-borne diseases, and infection prevention and control policies and procedures in the critical care unit lead to better management and prevention of BBV and increased safety for both staff and patients. Where direct educational update on the topics is not readily available, critical care nurses may take the initiative to perform independent learning on the topic in line with the development of their professional portfolio. Professional literature and readings on the topic are widely available and act as a good resource for the nurse looking to explore this topic within their portfolio.

HIV, HBV, HCV, and syphilis co-infections among patients attending the STD clinics of district hospitals in Northern India

Background Hepatitis B virus (HBV) is a global health issue, particularly among healthcare personnel, including students because of its occupational exposure pattern. Healthcare Workers and medical students are recommended to have better knowledge, attitudes and good practices and vaccination toward infection control in general and HBV in particular. This study aimed to assess the knowledge, attitudes, and practices of medical students from North Sudan regarding HBV and its vaccination coverage. Methods A cross-sectional study was conducted from January to June 2023 among medical students in North Sudan. Data were collected using a structured scale using online Google Forms. Descriptive and comparative analyses were performed using SPSS version 26. Statistical significance was set at p ≤ 0.05. Results A total of 426 medical students were included in the study. The majority had good knowledge about HBV (86%) and its transmission methods (77%). The majority showed a favorable attitude (77%). The practice score was however very low (15.5%). Older age and advanced academic level were significantly associated with good knowledge (aOR: 3.9; CI 95% [3.69–12.92]; p = 0.016, and aOR: 2.6; CI 95% [1.16–6.15]; p = 0.020, respectively). Only a third of the students were vaccinated (33.0%), with only a few of them received complete doses (18.6%). Conclusion Students from medical colleges in North Sudan had good knowledge and favorable attitudes toward HBV. However, good practice was low. Older age and advanced academic level were significantly associated with knowledge level. Vaccination coverage was also low among the students in this study.
