Between July 2016 and January 2017, 37 confirmed cases of hepatitis A with two unique IA genotype strains primarily among men who have sex with men, were reported across eight areas in England and Northern Ireland. Epidemiological and laboratory investigations indicate that these strains may have been imported several times from Spain, with secondary sexual transmission in the United Kingdom. Local and national public health services are collaborating to control this ongoing outbreak. This article is copyright of The Authors, 2017.

Vietnamese American men are over 10 times more likely to be diagnosed with liver cancer than their white counterparts. This health disparity is attributable to high rates of hepatitis B virus (HBV) infection. Our study objective was to examine factors associated with HBV testing among Vietnamese men. A population-based survey was conducted in Seattle. The questionnaire content was guided by an earlier qualitative study and the Health Behavior Framework. The survey was completed by 345 men (response rate: 80%). About one-third (34%) of the respondents reported they had not been tested for HBV. The following factors were associated (P < 0.01) with previous testing in bivariate comparisons: having a regular source of care and regular provider; knowing that HBV can be spread during childbirth; believing HBV can cause liver cancer; and doctor(s) had recommended testing as well as had asked doctor(s) for testing. Three variables were independently associated with HBV testing in a logistic regression model: regular source of care (OR = 4.5; 95% CI = 2.6-7.9), physician recommendation (OR = 2.3, 95% CI = 1.3-4.0), and knowing HBV can be spread during childbirth (OR = 2.1; 95% CI = 1.2-3.9). Low levels of HBV testing remain a public health problem in some Vietnamese American sub-groups. Health education about HBV transmission may stimulate patients to seek testing. Intervention programs should specifically target Vietnamese men without a regular source of health care and physicians who serve Vietnamese communities.

Although vaccination against hepatitis A virus (HAV) is essential for human immunodeficiency virus (HIV)-infected patients, the uptake of HAV vaccine is reported to be very low. From 2007 to 2012, 912 HIV-infected men in Athens, Greece were screened for exposure to HAV. Two doses of an HAV vaccine were recommended to 569 eligible patients. Reminder cards with scheduled vaccination visits were given to each patient. Among eligible patients, 62.2% (354/569) received both doses. Patients who were fully vaccinated compared with non-adherent patients were natives, older, had undetectable HIV viral load, higher CD4 T cell counts and lower nadir CD4 T cell counts. Multivariate logistic regression revealed that the patient's country of origin (p = 0.024; OR = 2.712; 95% CI, 1.139-6.457), CD4 T cell count (p < 0.001) and nadir CD4 T cell count (p < 0.001) were factors directly associated with adherence. In conclusion, adherence to HAV vaccination was better than in previously published data. Because many of the factors related to vaccination completion are parameters of HIV infection, it appears that physician interest in HIV care and vaccination planning is crucial to enhancing vaccine uptake. © The Author(s) 2015.

Hepatic cyst infection is a potentially severe complication in cystic disease. Treatment demands effective antibiotic concentrations within the infected cyst. The aim of this study was to use elective hepatic cyst drainage as a unique pharmacokinetic model to investigate whether cefazolin, a first-generation cephalosporin, is able to penetrate hepatic cysts. Patients scheduled to undergo percutaneous aspiration sclerotherapy of a symptomatic non-infected, non-neoplastic hepatic cyst were eligible for this study. All participants received a single perioperative prophylactic dose of cefazolin (1000 mg, intravenously). We collected blood and cyst fluid samples to determine total and unbound cefazolin concentrations using HPLC. The primary outcome was hepatic cyst penetration, expressed as the ratio (%) of unbound concentration of cefazolin in cyst fluid to plasma (both in mg/L). We included eight patients [male = 25%, median age = 60 years (IQR 54-75), median estimated glomerular filtration rate = 97 mL/min/1.73 m(2) (IQR 67-102) and median serum albumin = 40 g/L (IQR 37-40)]. We detected low concentrations of unbound cefazolin in cyst fluid (≤1.0 mg/L). The median plasma unbound cefazolin peak level (immediately after cefazolin administration) was 36.6 mg/L (IQR 23.7-54.1) and the level at the time of cyst fluid aspiration was 16.1 mg/L (IQR 13.0-20.1). In total, the hepatic cyst penetration of free cefazolin was only 2.2% (IQR 0.7-5.2). We developed a study model to investigate the penetration of antibiotics into hepatic cysts. Cefazolin did not reach adequate intracystic concentrations. Future studies should explore alternatives. © The Author 2016.

Since February 2017, an increase of acute hepatitis A (AHA) cases has been notified in North of France. We aimed to report clinical and virological features of 49 cases treated in three hospitals in Lille European Metropolis (LEM). All adult patients treated for AHA in 3 LEM hospitals between 20 February and 5 July 2017 were included. Demographic characteristics, exposure risk factors to hepatitis A virus (HAV), AHA manifestations and concomitant sexually transmitted infections (STI) were retrospectively recorded. Forty-nine cases of AHA were diagnosed among which 34 (69%) were hospitalised. Severe AHA occurred in 7 (14%) patients. The median age of cases was 36 years. All cases except 1 were men and 32 (65%) were identified as men having sex with men (MSM). Eleven (23%) patients were HIV-infected, 5 were under HIV pre-exposure prophylaxis (PrEP), 6 had a history of HIV postexposure prophylaxis and 19 had a history of at least one STI. Only three patients had received HAV vaccine. Proportion of patients tested for syphilis, chlamydial and gonococcal infections was 75% (18/24) in those seen by sexual health specialists and 21% (6/29) in those seen by other specialists. At least one concomitant STI was diagnosed in 13 out of 24 tested patients (54%). RT-PCR sequencing was available for 38 cases and confirmed co-circulation of 3 different strains of subgenotype IA (VRD 521 2016: n=24, RIVM-HAV16-090: n=13, V16-25801: n=1), already identified in several European countries. We are facing an outbreak of AHA among MSM in the North of France with a high rate of hospitalisation. Analysis of cases highlighted missed opportunities of vaccination and lack of concomitant STI screening. Awareness among healthcare providers and MSM should be increased and HAV vaccination promoted. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Although hepatitis A virus (HAV) and hepatitis B virus (HBV) infections are vaccine-preventable diseases, few homeless parolees coming out of prisons and jails have received the hepatitis A and B vaccination series. The study focused on completion of the HAV and HBV vaccine series among homeless men on parole. The efficacy of three levels of peer coaching (PC) and nurse-delivered interventions was compared at 12-month follow-up: (a) intensive peer coaching and nurse case management (PC-NCM); (b) intensive PC intervention condition, with minimal nurse involvement; and (c) usual care (UC) intervention condition, which included minimal PC and nurse involvement. Furthermore, we assessed predictors of vaccine completion among this targeted sample. A randomized control trial was conducted with 600 recently paroled men to assess the impact of the three intervention conditions (PC-NCM vs. PC vs. UC) on reducing drug use and recidivism; of these, 345 seronegative, vaccine-eligible subjects were included in this analysis of completion of the Twinrix HAV/HBV vaccine. Logistic regression was added to assess predictors of completion of the HAV/HBV vaccine series and chi-square analysis to compare completion rates across the three levels of intervention. Vaccine completion rate for the intervention conditions were 75.4% (PC-NCM), 71.8% (PC), and 71.9% (UC; p = .78). Predictors of vaccine noncompletion included being Asian and Pacific Islander, experiencing high levels of hostility, positive social support, reporting a history of injection drug use, being released early from California prisons, and being admitted for psychiatric illness. Predictors of vaccine series completion included reporting having six or more friends, recent cocaine use, and staying in drug treatment for at least 90 days. Findings allow greater understanding of factors affecting vaccination completion in order to design more effective programs among the high-risk population of men recently released from

To present the first national estimate of the sociodemographic, clinical, and behavioral characteristics of HIV-positive transgender men receiving medical care in the United States. This analysis included pooled interview and medical record data from the 2009 to 2014 cycles of the Medical Monitoring Project, which used a 3-stage, probability-proportional-to-size sampling methodology. Transgender men accounted for 0.16% of all adults and 11% of all transgender adults receiving HIV medical care in the United States from 2009 to 2014. Of these HIV-positive transgender men receiving medical care, approximately 47% lived in poverty, 69% had at least 1 unmet ancillary service need, 23% met criteria for depression, 69% were virally suppressed at their last test, and 60% had sustained viral suppression over the previous 12 months. Although they constitute a small proportion of all HIV-positive patients, more than 1 in 10 transgender HIV-positive patients were transgender men. Many experienced socioeconomic challenges, unmet needs for ancillary services, and suboptimal health outcomes. Attention to the challenges facing HIV-positive transgender men may be necessary to achieve the National HIV/AIDS Strategy goals of decreasing disparities and improving health outcomes among transgender persons.

Incarcerated men in the US are at increased risk for HIV, STDs and hepatitis, and many men leaving prison have unprotected sex with a primary female partner immediately following release from prison. This paper addresses risk to the primary female partners of men being released from prison (N = 106) by examining the prevalence of men's concurrent unprotected sex with other partners or needle sharing prior to and following release from prison (concurrent risk). Rates of concurrent risk were 46% prior to incarceration, 18% one month post release, and 24% three months post release. Multivariate analysis showed concurrent risk was significantly associated with having a female partner who had one or more HIV/STD risk factors and having a history of injection drug use. Findings demonstrate need for prevention programs for incarcerated men and their female partners.

This phase 3b randomized, open-label study evaluated the immunogenicity and safety of coadministration of a hepatitis A and/or B vaccine with a quadrivalent oligosaccharide meningococcal CRM197 -conjugate vaccine (MenACWY-CRM), in the context of an accelerated hepatitis A and/or B immunization schedule. A total of 252 healthy adult subjects were randomized to three groups to receive hepatitis A/B only (HepA/B), hepatitis A/B coadministered with MenACWY-CRM (HepA/B+MenACWY-CRM), or MenACWY-CRM only (MenACWY-CRM). Hepatitis A and/or B vaccination was administered in the form of a single booster dose or a primary three-dose series, depending on the hepatitis A and/or B vaccination history of subjects. Antibody responses to hepatitis A/B vaccination were assessed 1 month following the last hepatitis A and/or B dose. Serum bactericidal activity with human complement (hSBA) against meningococcal serogroups A, C, W-135, and Y was assessed 1 month post-MenACWY-CRM vaccination. Safety was monitored throughout the study. At 1 month following the final hepatitis A and/or B vaccination, concomitant administration of hepatitis A/B and MenACWY-CRM was non-inferior to administration of hepatitis A/B alone in terms of geometric mean concentrations of antibodies against the hepatitis A and B antigens. One month post-MenACWY-CRM vaccination, the percentages of subjects achieving hSBA titers ≥8 for serogroups A, C, W-135, and Y in the HepA/B+MenACWY-CRM group (76, 87, 99, and 94%, respectively) were comparable to those in the MenACWY-CRM group (67, 82, 96, and 88%, respectively). The percentages of subjects reporting adverse events (AEs) were similar across study groups and a majority of the reported AEs were mild to moderate in nature. There were no study vaccine-related serious AEs. MenACWY-CRM can be administered concomitantly with a hepatitis A and/or B vaccine in the context of an accelerated hepatitis A and/or B immunization schedule without increasing safety concerns

HIV serostatus disclosure before sex can facilitate serosorting, condom use and potentially decrease the risk of HIV acquisition. However, few studies have evaluated HIV serostatus disclosure from partners before sex. We examined the rate and correlates of receiving HIV serostatus disclosure from regular and casual male partners before sex among an online sample of men who have sex with men (MSM) in China. An online cross-sectional study was conducted among MSM in eight Chinese cities in July 2016. Participants completed questions covering sociodemographic information, sexual behaviors, HIV testing (including HIV self-testing) history, self-reported HIV status, and post-test violence. In addition, participants were asked whether they received HIV serostatus disclosure from their most recent partners before sex. Overall, 2105 men completed the survey. Among them, 85.9% were never married, and 35.4% had high school or less education. A minority (20.6%, 346/1678; 17.8%, 287/1608) of men received HIV serostatus disclosure from their most recent regular and casual male partners, respectively. Multivariate analysis indicated that participants who ever self-tested for HIV were more likely to have received HIV status disclosure from regular [adjusted OR (aOR) = 1.92, 95% CI 1.50-2.44] and casual (aOR = 2.34, 95% CI 1.80-3.04) male partners compared to never self-tested participants. Compared to participants who had not received HIV status disclosure from regular partners, participants who received disclosure from regular male partners had higher likelihood in experiencing post-test violence (aOR = 5.18, 95% CI 1.53-17.58). Similar results were also found for receiving HIV serostatus disclosure from casual partners. This study showed that HIV serostatus disclosure from partners was uncommon among Chinese MSM. Interventions and further implementation research to facilitate safe disclosure are urgently needed for MSM.

In 2006, the authors examined intention to receive an HPV vaccine among 340 college students. A total of 138 men and 202 women completed questionnaires. The authors measured intention by asking participants how likely they would be to accept an HPV vaccine that prevented against (1) all HPV, (2) cervical cancer but not genital warts, (3) genital warts but not cervical cancer, and (4) both genital warts and cervical cancer. Men and women reported high intent to receive an HPV vaccine, although women did so at a significantly higher rate (77.5% vs 88.6%, respectively; p < .01). Men were less willing to receive a vaccine that prevents cervical cancer alone than they were to receive one that prevents cervical cancer and genital warts (34.1% vs 77.5%, p < .001). Intent to receive the vaccine was significantly greater among participants who reported more than 5 sex partners and correctly answered 2 or 3 HPV knowledge questions. Interest varied according to sexual history, according to knowledge about HPV, and (in men) according to vaccine target.

Hepatitis C virus (HCV) is a chronic infection of increasing importance, especially among people living with HIV/AIDS. Co-infection with HIV can accelerate progression of HCV liver disease to cirrhosis and end-stage liver failure and elevate the risk of hepatocellular carcinoma. Globally, men who have sex with men (MSM) and people who inject drugs are at increased risk of HCV infection compared with the general population. Few studies on HCV in these key populations have been done in South Africa (SA). To describe the disease burden of HCV in drug-using MSM who attend harm-reduction services at the Anova Health Institute's Health4Men clinic in Cape Town, SA. In 2012 - 2014, attendees of an MSM-focused harm-reduction programme were invited to participate in our study. After informed consent, participants completed a brief demographic questionnaire and underwent phlebotomy for anti-HCV antibody, hepatitis B virus (HBV) surface antigen and surface antibody testing. Participants received counselling and education with regard to their results. HIV status was extracted from the case notes of participants who had previously been tested at the study site. Data were analysed using standard statistical techniques. Forty-one MSM were enrolled - 11 (27.0%) tested anti-HCV antibody-positive, indicating prior exposure to HCV or chronic infection; 10/11 (91.0%) were positive for HBV surface antibodies, suggesting previous HBV exposure or vaccination; and 1 (2.0%) screened positive for HBV. Of the HCV-seropositive individuals, HIV status was known in 8/11; 3/8 (37.5%) were HIV-positive. We demonstrated a high burden of HCV exposure or infection among a small urban cohort of MSM who inject drugs. We recommend active screening of MSM (especially those who report drug use) for HCV, and the development of referral networks for access to treatment.

The Centers for Disease Control and Prevention recommend vaccination for men who have sex with men (MSM) and injection drug users against hepatitis A and B. This study is the first report of a hepatitis vaccination program in a United States jail with a combined vaccine using an accelerated schedule. Los Angeles County has the largest jail system in the nation and Men's Central Jail (MCJ) is the largest facility within that system. MCJ includes a unit for self-identified MSM, where approximately 2700 inmates are housed per year. Starting in August 2007, a combined hepatitis A and B vaccine was offered to all inmates housed in this special unit. Using an accelerated schedule (0-, 7-, 21-30 days, 12-month booster), a total of 3931 doses were administered to 1633 inmates as of June 2010. Of those, 77% received 2 doses, 58% received 3 doses, and 11% received the booster dose. Inmates who screened positive for a sexually transmitted infection in this unit were 1.3 times more likely to be vaccinated (95% CI 1.2-1.4) compared to others in the same housing unit who screened negative. Hepatitis vaccination initiatives can be successfully implemented in an urban jail among an extremely high-risk population using the accelerated, combined hepatitis A/B vaccine. Ours may be a useful model for other programs to vaccinate incarcerated populations. Copyright © 2012 Elsevier Ltd. All rights reserved.

Between December 2016 and June 2017, 19 Hepatitis A virus (HAV)-positive cases, 17 of which were among men who have sex with men (MSM) were identified in the Tel Aviv area. Seven of the 15 sewage samples collected between January and June 2017 were also HAV-positive. All sequences clustered with two of the three strains identified in the current European HAV outbreak. We demonstrate that despite an efficient vaccination programme, HAV can still be transmitted to an unvaccinated high-risk population. This article is copyright of The Authors, 2017.

Between December 2016 and June 2017, 19 Hepatitis A virus (HAV)-positive cases, 17 of which were among men who have sex with men (MSM) were identified in the Tel Aviv area. Seven of the 15 sewage samples collected between January and June 2017 were also HAV-positive. All sequences clustered with two of the three strains identified in the current European HAV outbreak. We demonstrate that despite an efficient vaccination programme, HAV can still be transmitted to an unvaccinated high-risk population. PMID:28749336

Immunological responses to vaccination can differ depending on whether the vaccine is given alone or with other vaccines. This study was a retrospective evaluation of the immunogenicity of a tetravalent meningococcal conjugate vaccine for serogroups A, C, W, and Y (MenACWY) administered alone (n = 41) or concomitantly with other vaccines (n = 279) to U.S. military personnel (mean age, 21.6 years) entering the military between 2006 and 2008. Concomitant vaccines included tetanus/diphtheria (Td), inactivated polio vaccine (IPV), hepatitis vaccines, and various influenza vaccines, among others; two vaccine groups excluded Tdap and IPV. Immune responses were evaluated in baseline and postvaccination sera for Neisseria meningitidis serogroups C and Y 1 to 12 months (mean, 4.96 months) following vaccination. Functional antibodies were measured by using a serum bactericidal antibody assay with rabbit complement (rSBA) and by measurement of serogroup-specific immunoglobulin G (IgG) antibodies. The percentage of vaccinees reaching threshold levels (IgG concentration in serum, ≥2 μg/ml; rSBA titer, ≥8) corresponding to an immunologic response was higher postvaccination than at baseline (P < 0.001). Administration of MenACWY along with other vaccines was associated with higher geometric means of IgG concentrations and rSBA titers than those measured 4.60 months after a single dose of MenACWY. In addition, higher percentages of vaccinees reached the immunological threshold (range of odds ratios [ORs], 1.5 to 21.7) and more of them seroconverted (OR range, 1.8 to 4.8) when MenACWY was administered with any other vaccine than when administered alone. Additional prospective randomized clinical trials are needed to confirm the observed differences among groups in the immune response to MenACWY when given concomitantly with other vaccines to U.S. military personnel.

Cambodian immigrants are over 25 times more likely to have evidence of chronic hepatitis B infection than the general US population. Carriers of HBV are over 100 times more likely to develop liver cancer than non-carriers. Liver cancer incidence is the second leading cancer for Cambodian men and the sixth for Cambodian women. Despite this, this underserved population has received very little attention from health disparities researchers. Culturally and linguistically appropriate interventions are necessary to increase hepatitis B knowledge, serologic testing, and vaccination among Cambodian Americans. Eight group interviews were held with Cambodian American men (48) and women (49). Focus group discussion revealed unanticipated information about sociocultural influences on participants’ understanding about hepatitis B transmission, disease course, and prevention and treatment informed by humoral theories underlying Khmer medicine, by biomedicine, and by migration experiences. Our findings reveal the value of qualitative exploration to providing cultural context to biomedical information—a formula for effective health promotion and practice. PMID:20496000

For over a decade we have known of an epidemic of sexually transmitted hepatitis C virus (HCV) infection among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM), but there still remains significant controversy over which bodily fluid(s) are responsible for HCV transmission in these men. We enrolled HIV-infected MSM with recent and chronic HCV infection and quantified HCV from rectal fluid obtained by blind swab. We compared the rectal HCV viral load (VL) with paired blood HCV VL. We found rectal HCV shedding in 20 (47%) of 43 men, only one (2%) of whom had visible bleeding. Detection of rectal HCV shedding was associated with blood VL > 5 log 10 IU/mL (p = .01), and 85% with blood VL > 5 log 10 IU/mL had rectal shedding. The HCV VL of the rectal fluid ranged from 2.6 to 5.5 log 10 IU/mL. Based on the median rectal fluid VL, the surface of an average human penis would be exposed to at least 2,300 IU of HCV for the duration of anal intercourse. This study provides the first direct evidence to our knowledge that a sufficient quantity of HCV is shed into the rectum in HIV-infected men with HCV infection to directly infect an inserted penis or be passed indirectly through fomite-like transmission to the rectum of sex partner. We must develop an appropriate public health campaign to educate MSM about these routes of HCV infection to reverse the HCV epidemic among HIV-infected MSM. © The Author 2016.

Hepatitis B virus (HBV) and hepatitis C virus (HCV) cause substantial morbidity and mortality in low-income and middle-income countries, including China. WHO guidelines recommend men who have sex with men (MSM) receive HBV and HCV screening. The purpose of this study was to determine the proportion of MSM in China who have HBV and HCV tested and identify correlates of test uptake. We conducted an online cross-sectional survey of young MSM in China. Respondents were asked to report previous HBV and HCV testing, sociodemographic information, sexual risk factors for hepatitis infection, other STI testing and primary care physician (PCP) status. Associations were analysed by logistic regression. 503 eligible MSM completed the survey. 41.0% (206/503) of MSM had HCV tested, and 38.2% (60/157) of MSM with no or uncertain HBV vaccination had HBV tested. In multivariate analysis, HCV testing was correlated with HBV testing (adjusted OR (aOR) 22.98, 95% CI 12.11 to 43.60), HIV testing (aOR 3.64, 95% CI 1.92 to 6.91), HIV-positive status (aOR 1.78, 95% CI 1.07 to 2.98) and having a PCP (aOR 2.40, 95% CI 1.44 to 3.98). Among MSM with no or uncertain HBV vaccination, HBV testing was correlated with HCV testing (aOR 80.85, 95% CI 20.80 to 314.33), HIV testing (aOR 5.26, 95% CI 1.81 to 15.28), HIV-positive status (aOR 3.00, 95% CI 1.22 to 7.37) and having a PCP (aOR 2.69, 95% CI 1.00 to 7.26). Our data suggest many young MSM in China have not received hepatitis testing. HCV testing rates were lower than those recently reported among MSM in Australia and the USA. The strong correlation between HBV and HCV testing suggests bundled testing interventions may be useful for MSM in China. Men with a PCP were more likely to have received hepatitis testing, consistent with literature demonstrating the importance of primary care in expanding access to testing. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Hepatitis C is a common infection worldwide, but acute infection is often asymptomatic and difficult to diagnose. People coinfected with HIV and hepatitis C might progress to chronic liver disease more quickly. We present a case of a man infected with HIV with sexually acquired acute hepatitis C and discuss the immunology, natural history, and epidemiology of acute hepatitis C and coinfection with HIV. Several recent reports have documented acute hepatitis C among men who have sex with men who engage in high risk sexual practices and often have concomitant genital ulcer disease. We review treatment options for the medical management of acute hepatitis C and coinfection with HIV.

Likelihood of women vs. men to receive bachelor's degrees in physics at Stanford, 1900-1929.

Work by K. Tolley indicates that girls in mid to late 19th century U.S. high schools were more likely to study mathematics and natural philosophy (i.e., physics and astronomy) than were boys (who pursued the classics).* She also found that after the turn of the century women were more likely than men to receive bachelor's degrees in math and biological sciences at Stanford, but her sampling of every fifth year yielded too few data to be conclusive about physics. Reexamination of graduation lists at Stanford, yielding data for each year from 1900 to 1929, shows that, while absolute numbers were small, women were as likely as men to receive bachelor's degrees in physics during the first decade of the century, in the second decade they were notably more likely, and in the third their likelihood decreased substantially, while that of men rose to exceed that of women. (Women were much more likely to receive bachelor's degrees in math, exceeding the likelihood for men by an order of magnitude during the second and third decades.) *K.

A 53-year-old man who had a history of fluminant hepatitis caused by precore mutant hepatitis B virus (HBV) was admitted to our hospital for the treatment of relapsed non-Hodgkin's lymphoma in July 2000. At admission, serum levels of aspartate aminotransferase and alanine aminotransferase were normal, but he tested positive for HBs antigen. The titer was 64-fold by radioimmunoassay. We initiated lamivudine at a daily dose of 75 mg to prevent HBV proliferation during chemotherapy. By September 2000, he had received six courses of rituximab at 375 mg/m(2) and four courses of fludarabine and mitoxantrone. No hepatic damage was observed from the initiation of treatment until March 2001. At present, four months after the completion of chemotherapy, he continues lamivudine, and the titer of HBs antigen is low at 4-fold. Rituximab is usually associated with mild toxicity, usually limited to infusion periods. The drug is not generally associated with increased incidence of opportunistic infections. However, some case reports have been recently published on severe viral infections following administration of rituximab. These include fluminant hepatitis caused by HBV, pure red cell aplasia due to parvovirus B19 and fatal varicella-zoster infection. While it remains unknown whether rituximab can be safely administered in patients with chronic HBV infection, this case report suggested that prophylactic administration of lamivudine is beneficial for suppressing reactivation of HBV during chemotherapy including rituximab. Rituximab should be used cautiously for patients with HBV infection, but prophylactic administration of lamivudine may be beneficial for preventing reactivation of HBV.

Hepatitis C virus (HCV) infection is increasingly reported among gay and bisexual men. However, little is known about the personal and social dimensions of HCV-related experience among these men in Australia. An online survey of 474 Australian gay and bisexual men was conducted from August to December 2013. A subsample of 48 HCV mono-infected and HIV/HCV co-infected men was analysed to explore HCV knowledge, sources of information, unmet information needs and use of HCV-related services. More than half of respondents in the subsample were unaware that HIV infection increases the risk of sexually acquired HCV and most wanted information about how to prevent the sexual transmission of HCV. A majority of respondents requested gay-specific HCV services, and approximately similar proportions of men indicated that they would like these services delivered by a hepatitis organization, a lesbian, gay, bisexual, transgender and intersex (LGBTI) organization and a HIV organization. Men in receipt of HIV antiretroviral treatments were most likely to request that gay-specific HCV information and support services be delivered by a LGBTI or HIV organization (OR = 8.63). These findings suggest that a variety of organizations are required to address the information and support needs of Australian gay and bisexual men with HCV. © The Author 2015.

To identify risk factors for hepatitis C among HIV-positive men who have sex with men (MSM), focusing on potential sexual, nosocomial, and other non-sexual determinants. Outbreaks of hepatitis C virus (HCV) infections among HIV-positive MSM have been reported by clinicians in post-industrialized countries since 2000. The sexual acquisition of HCV by gay men who are HIV positive is not, however, fully understood. Between 2006 and 2008, a case-control study was embedded into a behavioural survey of MSM in Germany. Cases were HIV-positive and acutely HCV-co-infected, with no history of injection drug use. HIV-positive MSM without known HCV infection, matched for age group, served as controls. The HCV-serostatus of controls was assessed by serological testing of dried blood specimens. Univariable and multivariable regression analyses were used to identify factors independently associated with HCV-co-infection. 34 cases and 67 controls were included. Sex-associated rectal bleeding, receptive fisting and snorting cocaine/amphetamines, combined with group sex, were independently associated with case status. Among cases, surgical interventions overlapped with sex-associated rectal bleeding. Sexual practices leading to rectal bleeding, and snorting drugs in settings of increased HCV-prevalence are risk factors for acute hepatitis C. We suggest that sharing snorting equipment as well as sharing sexual partners might be modes of sexual transmission. Condoms and gloves may not provide adequate protection if they are contaminated with blood. Public health interventions for HIV-positive gay men should address the role of blood in sexual risk behaviour. Further research is needed into the interplay of proctosurgery and sex-associated rectal bleeding.

Hepatitis C virus (HCV) infection occurs among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) because of shared routes of transmission. To assess the association between HCV and HIV infection among MSM in Peru, we conducted a matched case-control study (162 HIV-positive cases and 324 HIV-negative controls) among participants of an HIV sentinel surveillance survey in six urban cities. The HCV infection was initially screened using anti-HCV ELISA and immunoblot assay, and thereafter confirmed by the HCV RNA qualitative assay. Among cases, no confirmed HCV infection was found while among controls, only two confirmed HCV infections were reported (0.62%). This matched case-control reports a very low probability of association between HCV and HIV co-infection and suggests a very low prevalence of HCV infection among MSM in Peru. PMID:19556587

Factors associated with hepatitis B vaccination among men who have sex with men: a systematic review of published research.

2017-05-01

This systematic review identified and synthesised evidence from published research regarding personal and environmental factors associated with hepatitis B virus (HBV) vaccination uptake among gay men and other men who have sex with men (MSM) in low prevalence, high-income countries. A systematic literature search identified 18 eligible papers that addressed factors potentially associated with HBV vaccination uptake among MSM, of which 16 reported research conducted in the US. Studies assessed possible associations between HBV vaccination among MSM and socio-demographic characteristics, behavioural and social-cognitive factors and indicators of health service access. Converging evidence was found for associations between HBV vaccination and younger age, gay self-identification, and not using alcohol and drugs; evidence suggests a lack of association between HBV vaccination and ethnicity. There was converging evidence for associations between HBV vaccination and social-cognitive factors, in particular knowledge, perceived vulnerability and perceived severity regarding HBV infection, and perceived barriers to HBV vaccination. Evidence further supported associations between HBV vaccination and indicators of health service access. While research regarding factors associated with HBV vaccination among MSM remains limited, the identified correlates of HBV vaccination among MSM provide important guidance for the development of health promotion interventions to effectively increase coverage of HBV vaccination among MSM.

Hepatitis B virus (HBV) reactivation in the setting of rituximab use is a potentially fatal but preventable safety event. The rate of HBV screening and proportion of patients at risk who receive antiviral prophylaxis in patients initiating rituximab is unknown.We analyzed electronic health record (EHR) data from 2 health systems, a university center and a safety net health system, including diagnosis grouper codes, problem lists, medications, laboratory results, procedures codes, clinical encounter notes, and scanned documents. We identified all patients who received rituximab between 6/1/2012 and 1/1/2016. We calculated the proportion of rituximab users with inadequate screening for HBV according to the Centers for Disease Control guidelines for detecting latent HBV infection before their first rituximab infusion during the study period. We also assessed the proportion of patients with positive hepatitis B screening tests who were prescribed antiviral prophylaxis. Finally, we characterized safety failures and adverse events.We included 926 patients from the university and 132 patients from the safety net health system. Sixty-one percent of patients from the university had adequate screening for HBV compared with 90% from the safety net. Among patients at risk for reactivation based on results of HBV testing, 66% and 92% received antiviral prophylaxis at the university and safety net, respectively.We found wide variations in hepatitis B screening practices among patients receiving rituximab, resulting in unnecessary risks to patients. Interventions should be developed to improve patient safety procedures in this high-risk patient population.

Since epidemiologic trends of hepatitis A are changing worldwide, we studied its seroprevalence in Mumbai, which is thought to be a high-endemicity area. The immunogenicity and safety of a hepatitis A vaccine were also studied. Six hundred and seventy subjects (456 men; age range 6 mo-60 y) answered a questionnaire on social and medical history. Qualitative analysis of total anti-HAV was performed in all subjects by ELISA. One hundred and seven of 147 anti-HAV negative subjects received hepatitis A vaccine at months 0, 1 and 6. Subjects were followed up (months 1, 2, 6, 7) to look for side-effects and seroconversion. The seroprevalence of HAV was 523/670 (78%); 38% of children < 5 years were anti-HAV negative. Seroprevalence rates of 80% were reached by 15 years. Prevalence was lower in the higher socio-economic group (151/234; 64.5%) compared with the lower socio-economic group (372/436; 85%) (p < 0.001). One month after doses 1, 2 and 3 of the hepatitis A vaccine, seropositivity was 92%, 99% and 100%, respectively. Minor self-limited side-effects occurred in 19.5% of subjects; there were no major side-effects. The seroprevalence of anti-HAV is high in Mumbai. Seroprevalence is lower in the higher socio-economic groups. The hepatitis A vaccine is safe and immunogenic.

The exact mechanisms responsible for increased plasma triglyceride (TG) concentration in obese people are unclear, and it is not known whether excess energy intake per se is involved in the pathophysiology of this abnormality. The purpose of our study was to examine how excess energy intake from a balanced diet for 1 day affects very-low-density lipoprotein (VLDL)-TG kinetics and its putative regulators hepatic insulin sensitivity and plasma free fatty acid availability. We used stable isotope-labeled tracer methods to evaluate glucose and lipid kinetics in 8 overweight and obese men (age, 38 ± 3 years; body mass index, 33.7 ± 1.7 kg/m(2); means ± SEM) on 2 occasions (randomized crossover design): once, the day after they consumed a balanced diet that provided an amount of energy that matched their energy expenditure, and another time, the day after they consumed a balanced diet that provided 30% excess calories. Eight healthy, lean men (34 ± 1 years; 22.5 ± 0.6 kg/m(2)) were studied under isocaloric conditions only to provide a reference for normal lipid kinetics. VLDL-TG and VLDL-apolipoprotein B-100 (apoB-100) concentrations and secretion rates were significantly greater (P < .01) in overweight/obese compared with lean men. Hypercaloric, compared with isocaloric, feeding in overweight/obese men increased glucose rate of appearance in plasma (904 ± 21 vs 873 ± 26 μmol/min), the hepatic insulin resistance index (10.9 ± 2.2 vs 8.3 ± 1.8), and VLDL-apoB-100 concentration and secretion rate (1.91 ± 0.24 vs. 1.53 ± 0.13 nmol/min), whereas VLDL-apoB-100 plasma clearance rate, VLDL-TG secretion and plasma clearance rates, and free fatty acid rate of appearance in plasma were not affected by overfeeding. One day of moderate overfeeding (30% excess energy intake) stimulates hepatic glucose and VLDL-apo B-100 secretion rates but has no effect on hepatic and adipose tissue fatty acid metabolism in overweight/obese men.

Prostate cancer remains a common disease that is frequently treated with multimodal therapy. The goal of this study was to assess the impact of treatment of the primary tumor on survival in men who go onto receive chemotherapy for prostate cancer. Using surveillance, epidemiology and end results (SEER)-Medicare data from 1992 to 2009, we identified a cohort of 1614 men who received chemotherapy for prostate cancer. Primary outcomes were prostate cancer-specific mortality (PCSM) and all-cause mortality (ACM). We compared survival among men who had previously undergone radical prostatectomy (RP), radiation therapy (RT), or neither of these therapies. Propensity score adjusted Cox proportional hazard models and weighted Kaplan-Meier curves were used to assess survival. Compared to men who received no local treatment, PCSM was lower for men who received RP ± RT (HR 0.65, p < 0.01) and for those who received RT only (HR 0.79, p < 0.05). Patients receiving neither RP nor RT demonstrated higher PCSM and ACM than those receiving treatment in a weighted time-to-event analysis. Men who received RP + RT had longer mean time from diagnosis to initiation of chemotherapy (100.7 ± 47.7 months) than men with no local treatment (48.8 ± 35.0 months, p < 0.05). In patients who go on to receive chemotherapy, treatment of the primary tumor for prostate cancer appears to confer a survival advantage over those who do not receive primary treatment. These data suggest continued importance for local treatment of prostate cancer, even in patients at high risk of failing local therapy.

Hepatitis A vaccination is recommended for travelers to endemic countries. Several inactivated aluminum-adsorbed hepatitis A vaccines are available worldwide, but only one licensed hepatitis A vaccine is available in Japan. This vaccine is a lyophilized inactivated aluminum-free hepatitis A vaccine (Aimmugen®). The standard schedule of Aimmugen® is three doses (at 0, 2-4 weeks, and 6 months). Japanese people will go abroad after receiving 2 doses of Aimmugen®. Some long-term travelers will receive the third dose of hepatitis A vaccine at their destination, at 6-24 months after 2 doses of Aimmugen®. Aimmugen® is not available in countries other than Japan. They receive inactivated aluminum-adsorbed hepatitis A vaccine instead of a third dose of Aimmugen®. This study was undertaken to determine whether the booster vaccination with an aluminum-adsorbed hepatitis A vaccine is effective following two doses of Aimmugen®. Subjects were healthy Japanese adults aged 20 years or older who had received two doses of Aimmugen®. Subjects received a booster dose of Havrix®1440 intramuscularly as the third dose. Serology samples for hepatitis A virus antibody titers were taken 4-6 weeks later. Anti-hepatitis A virus antibody titers were measured by an inhibition enzyme-linked immunosorbent assay. Subjects were 20 healthy Japanese adults, 6 men and 14 women. The mean age ± standard deviation was 37.2 ± 13.3. The seroprotection rate (SPR, anti-hepatitis A virus antibody titer ≥10 mIU/mL) was 85% at enrollment, and increased to 100% after vaccination with Havrix®. The geometric mean anti-hepatitis A virus antibody titer increased from 39.8 mIU/mL to 2938.2 mIU/mL. The three scheduled doses consisting of two doses of Aimmugen® plus a third dose with Havrix® is more immunogenic than using only two doses of Aimmugen®. The vaccination with Havrix® could be allowed to be used instead of a third dose of Aimmugen®. (UMIN000009351). Copyright © 2017 Elsevier Ltd. All

To explore whether the immunization with high-dose (60μg) hepatitis B vaccines in patients receiving methadone maintenance treatment (MMT) could yield a superior protection against hepatitis B infection than did the standard dose (20μg). We conducted a randomized, double-blinded, parallel-controlled trial in MMT patients. Patients with serologically negative hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) were randomized in a ratio of 1:1 to receive three intramuscular injections of 20μg or 60μg recombinant hepatitis B vaccine at months 0, 1, and 6. Serum HBsAg and anti-HBs were measured at months 7 and 12 post-vaccination to assess the immunogenicity. A total of 196 MMT patients were randomized and 195 received at least one injection (98 and 97 in 20 and 60μg vaccine groups, respectively). The 60μg vaccine group showed a seroconversion of anti-HBs of 87.3%, high-level response rate of 56.3%, and GMC of 742.9mIU/mL at month 7. While these results were numerically higher than the 20μg group, a statistical difference was not found. HIV infection and concomitant drug abuse were negatively associated with the robust immune responses. 7.7% of MMT patients receiving at least one dose of vaccine reported solicited adverse reactions within 7days after vaccination, 2.6% reported unsolicited adverse reactions within 28days after vaccination. None of the MMT patients reported serious adverse events or became HBsAg positive during the follow-up. The three-dose regimen of 60μg recombinant hepatitis B vaccine at months 0, 1, and 6 can yield a similar immunogenicity among MMT patients as compared to the 20μg vaccine.

Homeless men are highly vulnerable to acquisition of the hepatitis C virus (HCV) compared to the general population. In Brazil, a country of continental dimensions, the extent of HCV infection in this population remains unknown. The objective of this study is to investigate the epidemiological profile of exposure to HCV in homeless men in Central Brazil. A Cross-sectional study was conducted in 481 men aged over 18 years attending therapeutic communities specialized in the recovery and reintegration of homeless people. Participants were tested for anti-HCV markers using rapid tests. Poisson regression analysis was used to verify the risk factors associated with exposure to HCV. The prevalence of HCV exposure was 2.5% (95.0% CI: 1.4 to 4.3%) and was associated with age, absence of family life, injection drug use, number of sexual partners, and history of sexually transmitted infections (STI). Participants reported multiple risk behaviors, such as alcohol (78.9%), cocaine (37.1%) and/or crack use (53.1%), and inconsistent condom use (82.6%). Injection drug use was reported by 8.7% of participants. The prevalence of HCV infection among homeless men was relatively high. Several risk behaviors were commonly reported, which shows the high vulnerability of this population. These findings emphasize the need for the development of specific strategies to reduce the risk of HCV among homeless men.

Studies found an association between decreased 25-OH vitamin D blood level and prostate cancer progression. Vitamin D supplementation is controversial and dosage recommendations inconsistent. This study identified factors associated with 25-OH vitamin D levels and whether vitamin D supplementation with 800 IU/day raised vitamin D levels in prostate cancer patients receiving androgen deprivation therapy (ADT). We recruited 108 men treated with ADT for ≥9 months from eight cancer and urology practices. Sections of the NHANES 2005-2006 questionnaire and Canadian Fitness Survey were completed identifying age, ethnicity, length of ADT use, calcium supplementation ≥1000 IU mg/day, body mass index, exercise, alcohol and tobacco use, and vitamin D supplementation ≥800 IU/daily. Blood was collected for 25-OH vitamin D analysis. The majority of men (66%) had blood levels of 25-OH vitamin D <32 ng/mL. Regression analysis showed vitamin D supplementation (β = 6.556, CI 1.463, 11.650; p = .012) and African American ethnicity (β = -7.816, CI -12.996, -2.635; p = .003) is associated with 25-OH vitamin D level after controlling age and tobacco use. Findings support current recommendations for supplementation with ≥800 IU vitamin D/day for men receiving ADT. Nurse practitioners caring for prostate cancer patients receiving ADT should include vitamin D monitoring and supplementation. ©2014 American Association of Nurse Practitioners 2014.

To estimate the prevalence of human immunodeficiency virus (HIV) infection and risk behaviors among young homosexual and bisexual men sampled from public venues in San Francisco and Berkeley, Calif. A survey of 425 young homosexual and bisexual men sampled from 26 locations during 1992 and 1993. Participants were interviewed and blood specimens were drawn and tested for HIV, level of CD4+ T lymphocytes, and markers of hepatitis B and syphilis. Public venues in San Francisco and Berkeley, including street corners and sidewalks, dance clubs, bars, and parks. Homosexual and bisexual men aged 17 to 22 years. Prevalence of HIV infection and risk behaviors. The HIV seroprevalence was 9.4% (95% confidence interval, 6.8% to 12.6%). The prevalence of markers for hepatitis B was 19.8% (95% confidence interval, 16.1% to 23.9%), and that for syphilis was 1.0% (95% confidence interval, 0.3% to 2.4%). The HIV seroprevalence was significantly higher among African Americans (21.2%) than among other racial/ethnic groups (P = .002). Approximately one third (32.7%) of the participants reported unprotected anal intercourse, and 11.8% reported injecting drug use in the previous 6 months. At the time of interview, 70.0% of the HIV-infected men did not know that they were HIV seropositive, and only 22.5% were receiving medical care for HIV infection. The prevalence of HIV infection is high among this young population of homosexual and bisexual men, particularly among young African-American men. The high rates of HIV-related risk behaviors suggest a considerable risk for HIV transmission in this population. Prevention programs and health services need to be tailored to address the needs of a new generation of homosexual and bisexual men.

Adult vaccination compliance rates vary according to sample and type of vaccine administered (influenza, pneumococcal). This study looked at vaccination of a community sample of low-income, minority adults. Nurses offered free vaccination for hepatitis A and B in the form of the combined Twinrix vaccine to adults on a walk-in basis. In addition to dosing information, participants completed the Risk Behavior Assessment, the Coping Strategies Indicator and the Cardiovascular Risk Assessment. Skaff's extended Health Belief Model was used as the theoretical framework. Count regression was used to model receipt of one, two, or three doses. The majority of participants were male with a mean age of 40 years. The distribution of doses was: 173 individuals (27.6%) received one dose only, 261 (41.7%) received two doses, and 191 (30.5%) received three doses of vaccine. The multivariate count regression model including being male, having previously been told by a health care provider that one has syphilis, having severe negative emotions, and perceived social support were associated with participants' receiving fewer doses of hepatitis vaccine. A greater problem-solving score was associated with a higher number of vaccine doses received. Despite free vaccinations offered in an easily accessible community setting, the majority of participants failed to complete the hepatitis vaccine series. More effort is needed to get adult men to participate in hepatitis vaccination clinics. Additional research is necessary to understand barriers other than cost to adults receiving vaccination. © 2016 Wiley Periodicals, Inc.

Data on the incidence of adverse liver outcomes are limited for cancer patients with chronic (hepatitis B surface antigen [HBsAg]-positive/hepatitis B core antibody [anti-HBc]-positive) or past (HBsAg-negative/anti-HBc-positive) hepatitis B virus (HBV) after chemotherapy. This study was aimed at determining the impact of test timing and anti-HBV therapy on adverse liver outcomes in these patients. Patients with solid or hematologic malignancies who received chemotherapy between 2004 and 2011 were retrospectively studied. HBV testing and anti-HBV therapy were defined as early at the initiation of cancer therapy and as late after initiation. Outcomes included hepatitis flares, hepatic impairment, liver failure, and death. Time-to-event analysis was used to determine incidence, and multivariate hazard models were used to determine predictors of outcomes. There were 18,688 study patients (80.4% with solid tumors). The prevalence of chronic HBV was 1.1% (52 of 4905), and the prevalence of past HBV was 7.1% (350 of 4905). Among patients with solid tumors, late identification of chronic HBV was associated with a higher risk of hepatitis flare (hazard ratio [HR], 4.02; 95% confidence interval [CI], 1.26-12.86), hepatic impairment (HR, 8.48; 95% CI, 1.86-38.66), liver failure (HR, 9.38; 95% CI, 1.50-58.86), and death (HR, 3.90; 95% CI, 1.19-12.83) in comparison with early identification. Among patients with hematologic malignancies and chronic HBV, the risk of death was 7.8 (95% CI, 1.73-35.27) times higher for persons with late initiation of anti-HBV therapy versus early initiation. Patients with late identification of chronic HBV had late or no anti-HBV therapy. Chronic HBV predicted liver failure in patients with solid or hematologic malignancies, whereas male sex and late identification were predictors for patients with solid tumors. Early identification correlates with early anti-HBV therapy and reduces the risk of liver failure and death in chronic HBV patients

In this study, we aimed to determine the effects of hepatitis B virus (HBV) infection on sperm quality and the outcome of assisted reproductive technology (ART). A total of 916 men (457 HBV-positive and 459 HBV-negative) seeking fertility assistance from January 2008 to December 2009 at the Women's Hospital in the School of Medicine at Zhejiang University were analysed for semen parameters. Couples in which the men were hepatitis B surface antigen (HBsAg)-seropositive were categorized as HBV-positive and included 587 in vitro fertilisation (IVF) and 325 intracytoplasmic sperm injection (ICSI) cycles from January 2004 to December 2009; negative controls were matched for female age, date of ova retrieval, ART approach used (IVF or ICSI) and randomized in a ratio of 1:1 according to the ART treatment cycles (587 for IVF and 325 for ICSI). HBV-infected men exhibited lower semen volume, lower total sperm count as well as poor sperm motility and morphology (P<0.05) when compared to control individuals. Rates of two-pronuclear (2PN) fertilisation, high-grade embryo acquisition, implantation and clinical pregnancy were also lower among HBV-positive patients compared to those of HBV-negative patients after ICSI and embryo transfer (P<0.05); IVF outcomes were similar between the two groups (P>0.05). Logistic regression analysis showed that HBV infection independently contributed to increased rates of asthenozoospermia and oligozoospermia/azoospermia (P<0.05) as well as decreased rates of implantation and clinical pregnancy in ICSI cycles (P<0.05). Our results suggest that HBV infection in men is associated with poor sperm quality and worse ICSI and embryo transfer outcomes but does not affect the outcome of IVF and embryo transfer.

The Japan Society for Dialysis Therapy established "Guidelines for the Treatment of Hepatitis C Virus Infection in Dialysis Patients." We evaluated the status of HCV infection and the treatment of hemodialysis patients in Gunma prefecture. Questionnaires concerning the infection rate, recognition of the guidelines, and treatment status were sent to all 64 hospitals/clinics that had hemodialysis systems in Gunma prefecture. The hepatitis C virus-infected hemodialysis patients who received pegylated interferon (peg-IFN) were analyzed at Gunma University Hospital. The positive rate for hepatitis C virus antibody was 256/2582 hemodialysis patients (9.9%). The positive rate varied between institutions (range 0-40.0%; median 9.0%). All institutes recognized the establishment of the guidelines. Conventional or peg-IFN treatment was being given at 37.5% of the institutions. The other 62.5% institutions answered that they intended to provide the treatment in the future if collaboration with a hepatologist could be arranged. The most common answers regarding the indication for IFN treatment were as follows: few complications, under 60 years of age, more than 10 years of survival expected on hemodialysis. Eighteen patients received peg-IFN treatment. The sustained virological response rate of all patients was 33.3%, 0% in 1b/high viral titer, 50% in genotype 2, and 100% in genotype 2/low viral titer. The sustained virological response rate was worse in the patients with 1b/high viral load and diabetic nephropathy (P < 0.05). Recognition of the publication of the guidelines was high. However, the number of patients treated with peg-IFN was still low. Further enlightenment and cooperation between hemodialysis teams and hepatologists are therefore needed. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

The meningococcal groups C and Y and Haemophilus b (Hib) tetanus toxoid conjugate vaccine (HibMenCY-TT) contains Neisseria meningitidis serogroup C and Y capsular polysaccharide antigens, and Hib capsular polysaccharide [polyribosyl-ribitol-phosphate (PRP)]. The HibMenCY-TT vaccine is available in the USA for use as active immunization to prevent invasive disease caused by N. meningitidis serogroups C (MenC) and Y (MenY), and Hib in children 6 weeks-18 months of age. HibMenCY-TT is the first meningococcal vaccine available for use in the USA that can be administered to infants as young as 6 weeks of age. In a randomized, controlled, phase III clinical trial, the HibMenCY-TT vaccine, administered to infants at 2, 4, 6 and 12-15 months of age, was immunogenic against MenC and MenY, and met the prespecified criteria for immunogenicity. Anti-PRP antibodies, which have been shown to correlate with protection against Hib invasive disease, were also induced in the infants who received the HibMenCY-TT vaccine, with induced levels of this antibody noninferior to those occurring in the control group of infants who received a Hib tetanus toxoid conjugate vaccine at 2, 4, and 6 months and a single dose of Hib conjugated to N. meningitidis outer membrane protein at 12-15 months. In several randomized, controlled clinical trials, HibMenCY-TT was coadministered with vaccines that are routinely administered to infants and toddlers in the USA. These vaccines included: diphtheria and tetanus toxoids and acellular pertussis adsorbed, hepatitis B (recombinant) and inactivated poliovirus vaccine combined; 7-valent Streptococcus pneumoniae polysaccharide conjugate vaccine; measles, mumps and rubella vaccine; and varicella vaccine. Coadministration of these vaccines did not interfere with the immunogenicity of the HibMenCY-TT vaccine. Similarly, immune responses to the coadministered vaccines were not affected by the HibMenCY-TT vaccine. The tolerability profile of the HibMen

A study was undertaken to determine the impact of prior coronary revascularization (angioplasty, stent, or coronary artery bypass graft) on the risk of all-cause mortality after neoadjuvant hormonal therapy (HT) for prostate cancer (PC) in men with a history of coronary artery disease (CAD)-induced congestive heart failure (CHF) or myocardial infarction (MI). Among 7839 men who received radiation with or without a median of 4 months of HT for PC from 1991 to 2006, 495 (6.3%) had CAD-induced CHF or MI and formed the study cohort. Of these men, 250 (50.5%) had been revascularized before treatment for PC. Cox regression was used to determine whether HT increased the risk of all-cause mortality, and whether revascularization altered this risk, after adjusting for known PC prognostic factors and a propensity score for revascularization. Median follow-up was 4.1 years. Neoadjuvant HT was associated with an increased risk of all-cause mortality (28.9% vs 15.7% at 5 years; adjusted hazard ratio [HR], 1.73; 95% confidence interval [CI], 1.13-2.64; P = .01). Men who received HT without revascularization had the highest risk of all-cause mortality (33.3%; adjusted HR, 1.48; 95% CI, 1.01-2.18; P = .047), whereas men who were revascularized and did not receive HT had the lowest risk of all-cause mortality (9.4%; adjusted HR, 0.51; 95% CI, 0.28-0.93; P = .028). The reference group had an intermediate risk of all-cause mortality (23.4%) and was comprised of men in whom HT use and revascularization were either both given or both withheld. In men with a history of CAD-induced CHF or MI, neoadjuvant HT is associated with an excess risk of mortality, which appears to be reduced but not eliminated by prior revascularization.

Lamivudine associated mutation and resistance reduces the effect of anti-hepatitis B virus. Pharmacological studies in cell and animal model suggest that Chinese herbal medicines (CHMs) have anti-hepatitis B virus effect. Observational studies offer mixed results. The aim of this study was to evaluate the relation between the use of CHMs and outcome in patients with chronic hepatitis B receiving lamivudine treatment and further estimate the association of Jia-Wei-Xiao-Yao-Sang (JWXYS) use with mortality of those patients. We conducted a cohort study among patients age 20-90 years within a National Health Insurance Healthcare system. Information on the use of CHMs and covariates were obtained from Taiwan National Health Insurance Research Database. We used Cox proportional hazards models to estimate the hazard ratio and 95% confidence intervals (95% CI) for all-cause mortality among CHMs users compared to nonusers. Among 1037 patients studied from 2004 to 2011, median follow-up time 5.3 years and 88 deaths were identified. During the study period, 49% of patients used CHMs and the median duration of use was 2.4 years. We found that significant difference on all-cause mortality among CHMs users (aHR=0.45, 95% CI: 0.27-0.76) compared to CHMs nonusers. All-cause mortality also differed by JWXYS use (aHR=0.26, 95% CI: 0.08-0.83). This study reveals that the use of CHMs may lower the risk of death in patients with chronic hepatitis B receiving lamivudine treatment. Further randomized-controlled trials are required to validate these findings. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Nonalcoholic fatty liver disease (NAFLD) has different prevalence rates in various parts of the world and is a risk factor for diabetes and cardiovascular disease that could progress to nonalcoholic steatohepatitis, cirrhosis, and liver failure. The current study aimed to investigate the effect of Aerobic Training (AT) and resistance training (RT) on hepatic fat content and liver enzyme levels in Iranian men. In a randomized clinical trial study, 30 men with clinically defined NAFLD were allocated into three groups (aerobic, resistance and control). An aerobic group program consisted of 45 minutes of aerobic exercise at 60% - 75% maximum heart rate intensity, a resistance group performed seven resistance exercises at intensity of 50% - 70% of 1 repetition maximum (1RM ) and the control group had no exercise training program during the study. Before and after training, anthropometry, insulin sensitivity, liver enzymes and hepatic fat were elevated. After training, hepatic fat content was markedly reduced, to a similar extent, in both the aerobic and resistance exercise training groups (P ≤ 0.05). In the two exercise training groups, alanine amino transferase and aspartate amino transferase serum levels were significantly decreased compared to the control group (P = 0.002) and (P = 0.02), respectively. Moreover, body fat (%), fat mass (kg), homeostasis model assessment insulin resistance (HOMI-IR) were all improved in the AT and RT. These changes in the AT group were independent of weight loss. This study demonstrated that RT and AT are equally effective in reducing hepatic fat content and liver enzyme levels among patients with NAFLD. However, aerobic exercise specifically improves NAFLD independent of any change in body weight.

Objective: To report late toxicity outcomes from a randomized trial comparing conventional and hypofractionated prostate radiation therapy and to identify dosimetric and clinical parameters associated with late toxicity after hypofractionated treatment. Methods and Materials: Men with localized prostate cancer were enrolled in a trial that randomized men to either conventionally fractionated intensity modulated radiation therapy (CIMRT, 75.6 Gy in 1.8-Gy fractions) or to dose-escalated hypofractionated IMRT (HIMRT, 72 Gy in 2.4-Gy fractions). Late (≥90 days after completion of radiation therapy) genitourinary (GU) and gastrointestinal (GI) toxicity were prospectively evaluated and scored according to modified Radiation Therapy Oncology Group criteria. Results: 101 men receivedmore » CIMRT and 102 men received HIMRT. The median age was 68, and the median follow-up time was 6.0 years. Twenty-eight percent had low-risk, 71% had intermediate-risk, and 1% had high-risk disease. There was no difference in late GU toxicity in men treated with CIMRT and HIMRT. The actuarial 5-year grade ≥2 GU toxicity was 16.5% after CIMRT and 15.8% after HIMRT (P=.97). There was a nonsignificant numeric increase in late GI toxicity in men treated with HIMRT compared with men treated with CIMRT. The actuarial 5-year grade ≥2 GI toxicity was 5.1% after CIMRT and 10.0% after HIMRT (P=.11). In men receiving HIMRT, the proportion of rectum receiving 36.9 Gy, 46.2 Gy, 64.6 Gy, and 73.9 Gy was associated with the development of late GI toxicity (P<.05). The 5-year actuarial grade ≥2 GI toxicity was 27.3% in men with R64.6Gy ≥ 20% but only 6.0% in men with R64.6Gy < 20% (P=.016). Conclusions: Dose-escalated IMRT using a moderate hypofractionation regimen (72 Gy in 2.4-Gy fractions) can be delivered safely with limited grade 2 or 3 late toxicity. Minimizing the proportion of rectum that receives moderate and high dose decreases the risk of late rectal toxicity after this

Vaccination to protect against hepatitis A and B should be part of the routine management of patients with chronic liver disease (CLD). To evaluate the efficacy and safety of hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccination in a group of patients with CLD and to assess the presence of factors predictive of response. We performed a prospective, single-center study in 194 patients (123 men, 71 women; mean age, 48.9+/-10.7 years) with CLD: 107 with chronic hepatitis (CH) and 87 with hepatic cirrhosis (HC), all Child-Pugh class A. The most frequent causes of CLD were HCV infection and alcohol. Patients negative for anti-HAV IgG received the HAV vaccination (1440 ELISA units in two doses) and those with negative HBV serology received the HBV vaccination ( three 20 microg doses). Patients with inadequate response to the latter vaccine received an additional double dose. Thirty patients received a combination vaccine (three doses). Sixty patients (31%) received the HAV vaccine and 150 (77%) patients received the HBV vaccine. Seroconversion was achieved by 91.6% of patients for HAV and by 57% of the patients for HBV. After the additional dose, the response increased to 74%. Efficacy was similar between CH and HC. HBV vaccination was less effective in HC than in CH and the seroconversion rate was significantly lower in patients with HC and previous decompensation. The combination vaccine (30 patients) was highly immunogenic. No adverse effects were registered. HAV vaccination has high efficacy in patients with CLD. Patients with HC respond weakly to HBV vaccination compared with those with CH and especially if there is prior decompensation. The combination vaccine seems particularly effective in patients with CLD. The three vaccines are safe.

At the end of 1998, universal hepatitis A+B vaccination of 12 year olds was introduced in Catalonia. The aim was to examine trends in hepatitis A during 2005-2015 and assess risk factors by age group. We carried out an observational epidemiological study of the incidence and risk factors of hepatitis A reported to the surveillance system. Information on exposure was recorded for each case for the 2-6 weeks before symptom onset. Spearman's coefficient was used to evaluate the trends of rates. The chi-square test was used to compare categorical. We studied 2621 hepatitis A cases; the age mean was 26.6 years (SD=18.2), and >50% of cases were in the 20-49 years age group. The incidence decreased from 3.28/100 000 in 2005 to 1.50/100 000 in 2015. The rate for women decreased over time (P = .008), but the reduction was not significant in men (P = .234). Men consistently had higher rates than women with the biggest difference being in the 20-34 years age group (rate 8.8 vs 2.8). The greatest risk factor was travel to an endemic country (42.1%) in the 0-19 years age group and male-to-male sexual contact (18.6%) in the 20-49 years age group. The case fatality rate in adults aged >49 years was 0.4%. In conclusion, the vaccination programme of preadolescents resulted in a reduction in hepatitis A cases. However, a significant amount of cases still appear in immigrants and men who have sex with men. Hepatitis A in adults is an emerging health problem that will require new strategies. © 2018 John Wiley & Sons Ltd.

We investigated whether there were racial/ethnic differences among young men who have sex with men (MSM) in their use of, perceived importance of, receipt of, and satisfaction with HIV prevention services received at health care providers (HCP) and HIV test providers (HTP) that explain racial disparities in HIV prevalence. Young men, aged 23 to 29 years, were interviewed and tested for HIV at randomly sampled MSM-identified venues in six U.S. cities from 1998 through 2000. Analyses were restricted to five U.S. cities that enrolled 50 or more black or Hispanic MSM. Among the 2,424 MSM enrolled, 1,522 (63%) reported using a HCP, and 1,268 (52%) reported having had an HIV test in the year prior to our interview. No racial/ethnic differences were found in using a HCP or testing for HIV. Compared with white MSM, black and Hispanic MSM were more likely to believe that HIV prevention services are important [respectively, AOR, 95% confidence interval (CI): 3.0, 1.97 to 4.51 and AOR, 95% CI: 2.7, 1.89 to 3.79], and were more likely to receive prevention services at their HCP (AOR, 95% CI: 2.5, 1.72 to 3.71 and AOR, 95% CI: 1.7, 1.18 to 2.41) and as likely to receive counseling services at their HTP. Blacks were more likely to be satisfied with the prevention services received at their HCP (AOR, 95% CI: 1.7, 1.14 to 2.65). Compared to white MSM, black and Hispanic MSM had equal or greater use of, perceived importance of, receipt of, and satisfaction with HIV prevention services. Differential experience with HIV prevention services does not explain the higher HIV prevalence among black and Hispanic MSM. PMID:18622708

Factors relating to transmission of viral hepatitis in a United States military population stationed in Thailand.

To determine the incidence of clinical and inapparent hepatitis in a US military population stationed in Thailand, the authors prospectively studied a cohort of 326 men during one year. Clinical hepatitis A occurred in one man (clinical attack rate = 3.1/1000 men/year), and clinical hepatitis B was found in four men (clinical attack rate = 12.3/1000 men/year). No non-A, non-B hepatitis was identified. There was no serologically identified inapparent hepatitis A but inapparent hepatitis B occurred in 17 men. The apparent/inapparent ratio for hepatitis B was 1:4.25. Serotype analysis suggested that hepatitis B virus largely originated from Thai contacts, although 23% of cases were derived from western sources. To determine the relative contribution of 16 statistically significant (out of 67 studied) behavioral variables to the transmission of HBV, a factor analysis and a multivariate correlation analysis were employed. Factor analysis indicated that social and sexual contact with the indigenous population, including prostitutes, residence within the Thai community and marijuana use were behavioral areas that were associated with the acquisition of hepatitis B. Residence in the Thai community during the first four-month period in Thailand, sexual contact with a prostitute during the third four-month period, and ever having maintained a Thai mistress were found to be significant and independent risk factors by multiple regression analysis.

Western Australian general practitioners may order Department of Health funded hepatitis A and B vaccines for patients newly notified with hepatitis C to prevent complications associated with co-infections. The aim of this study was to determine vaccination uptake of hepatitis C patients through this program. We reviewed hepatitis C notifications and hepatitis A and B vaccine orders received in 2007 and 2008 to determine the rate of vaccine uptake and course completion. Vaccination orders for initial doses were received for 37% (448/1209) of patients. Vaccination uptake was positively associated with age and non- Aboriginality. Final vaccination doses were ordered for 30% of patients for whom an initial order had been received. Uptake of hepatitis A and B vaccination was higher than that of similar populations. However, vaccination course completion was low. General practitioners need to emphasise to their patients the importance of completing a vaccine course.

Mortality and morbidity among military personnel and civilians during the 1930s and World War II from transmission of hepatitis during yellow fever vaccination: systematic review.

During World War II, nearly all US and Allied troops received yellow fever vaccine. Until May 1942, it was both grown and suspended in human serum. In April 1942, major epidemics of hepatitis occurred in US and Allied troops who had received yellow fever vaccine. A rapid and thorough investigation by the US surgeon general followed, and a directive was issued discontinuing the use of human serum in vaccine production. The large number of cases of hepatitis caused by the administration of this vaccine could have been avoided. Had authorities undertaken a thorough review of the literature, they would have discovered published reports, as early as 1885, of postvaccination epidemics of hepatitis in both men and horses. It would take 4 additional decades of experiments and epidemiological research before viruses of hepatitis A, B, C, D, and E were identified, their modes of transmission understood, and their genomes sequenced.

Co-administration of an investigational quadrivalent meningococcal serogroups A, C, W and Y tetanus toxoid conjugate vaccine (MenACWY-TT) with the fourth dose of diphtheria-tetanus-acellular pertussis vaccine (DTaP) at age 15-18 months was investigated in 3-dose Haemophilus influenzae type b-meningococcal serogroups C/Y conjugate vaccine (HibMenCY-TT)-primed toddlers. Infants were randomized (5:1) and primed at 2, 4 and 6 months of age with HibMenCY-TT and DTaP-hepatitis B-inactivated poliovirus (DTaP-HBV-IPV) vaccine, or Hib-TT and DTaP-HBV-IPV (Control). HibMenCY-TT+ DTaP-HBV-IPV vaccinees were re-randomized (2:2:1) to receive MenACWY-TT at 12-15 months and DTaP at 15-18 months (MenACWY-TT group); MenACWY-TT co-administered with DTaP at 15-18 months (Coad group); or HibMenCY-TT at 12-15 months and DTaP at 15-18 months (HibMenCY-TT group). Controls received DTaP at 15-18 months. Only children in the HibMenCY-TT group received a fourth dose of Hib conjugate vaccine due to Hib conjugate vaccine shortage at the time of the study. DTaP immunogenicity and reactogenicity were assessed one month post-vaccination. Pre-defined statistical non-inferiority criteria between Coad and Control groups were met for diphtheria, tetanus and filamentous haemagglutinin but not pertussis toxoid and pertactin. Following vaccination ≥99% of children had anti-diphtheria/anti-tetanus concentrations ≥1.0 IU/ml. Pertussis GMCs were lower in all investigational groups versus Control. In post hoc analyses, pertussis antibody concentrations were above those in infants following 3-dose DTaP primary vaccination in whom efficacy against pertussis was demonstrated (Schmitt, von König, et al., 1996; Schmitt, Schuind, et al., 1996). The reactogenicity profile of the Coad group was similar to DTaP administered alone. Routine booster DTaP was immunogenic with an acceptable safety profile when co-administered with MenACWY-TT vaccine in HibMenCY-TT-primed toddlers. These data support the

At the 2018 Conference on Retroviruses and Opportunistic Infections (CROI), there was a major focus on hepatitis C virus (HCV) elimination and improving each component of the hepatitis C care cascade. Several countries and cohorts have demonstrated the remarkable impact that universal HCV testing and unrestricted access to hepatitis C treatment can have on markedly reducing incident HCV infections and HCV infection prevalence, including in people who inject drugs and HIV/HCV-coinfected populations. However, in many settings, substantial barriers to widespread HCV treatment remain, including undiagnosed HCV infection, particularly in populations outside the standard "baby boomer" birth cohort (ie, born 1945-1965); restricted access to hepatitis C treatment in those with known HCV infection; reinfection with HCV; and migration of HCV-infected populations. Many innovative programs have successfully implemented HCV testing and treatment outside of traditional care settings, expanding access for harder-to-reach populations, which will be crucial to successful elimination efforts. Outbreaks of hepatitis A virus (HAV) infection continue to occur in among men who have sex with men and homeless populations in the United States, Europe, and Southeast Asia, highlighting the need for improved HAV vaccination programs for populations at risk.

Hepatitis B virus (HBV) is an important cause of comorbidity in human immunodeficiency virus (HIV)-infected individuals. The immunogenicity of HBV vaccination in children receiving highly active antiretroviral therapy (HAART) was investigated. HIV-infected children receiving HAART who had low to moderate HIV loads and who had previously received 3 doses of HBV vaccine were given an HBV vaccine booster. Concentrations of antibody to hepatitis B surface antigen (anti-HBs) were determined before vaccination and at weeks 8, 48, and 96. A subset of subjects was administered a subsequent dose, and anti-HBs was measured before and 1 and 4 weeks later. At entry, 24% of 204 subjects were seropositive. Vaccine response occurred in 46% on the basis of seropositivity 8 weeks after vaccination and in 37% on the basis of a 4-fold rise in antibody concentration. Of 69 subjects given another vaccination 4-5 years later, immunologic memory was exhibited by 45% on the basis of seropositivity 1 week after vaccination and by 29% on the basis of a 4-fold rise in antibody concentration at 1 week. Predictors of response and memory included higher nadir and current CD4 cell percentage, higher CD19 cell percentage, and undetectable HIV load. HIV-infected children frequently lack protective levels of anti-HBs after previous HBV vaccination, and a significant proportion of them do not respond to booster vaccination or demonstrate memory despite receiving HAART, leaving this population insufficiently protected from infection with HBV.

With the increasing incidence of breast cancer worldwide, in particular in southeast Asia (including Korea), and the common use of anthracyclines in the adjuvant and metastatic settings, the occurrence of Hepatitis B virus (HBV) reactivation may develop in this patient population. The use of prophylactic antiviral agents in cancer patients may result in a reduced HBV exacerbation. The purpose of the current study was to assess the efficacy of prophylactic lamivudine in reducing the incidence and severity of HBV reactivation in post-operative breast cancer patients undergoing adjuvant doxorubicin-containing chemotherapy. The medical records of patients undergoing anthracycline-based adjuvant chemotherapy at Samsung Medical Center between January 2001 and September 2008 were reviewed. From the database, 1912 breast cancer patients who had received anthracycline-based adjuvant chemotherapy were identified. Of 131 patients who were HBV surface antigen positive, 55 and 76 did and did not receive prophylactic lamivudine, respectively. In all, 30 patients (23%) developed hepatitis during doxorubicin-containing adjuvant chemotherapy. Of the 30 patients, 5 (9%) were in the prophylactic lamivudine group and 25 (33%) in the control group (P=0.001). In the prophylactic lamivudine group, there was significantly less HBV reactivation (1 patient (2%) vs 20 patients (16%); P=0.002), less disruption of chemotherapy (7 vs 14%; P=0.04), and less severe hepatitis (0 vs 17%; P=0.002). Prophylactic lamivudine significantly reduced the incidence and severity of HBV reactivation in breast cancer patients undergoing anthracycline-based adjuvant chemotherapy.

Limited prevalence data for HIV, hepatitis B surface antigen (HBsAg), and hepatitis C virus (HCV) exist for Afghanistan. We studied a cross-sectional sample of adult injection drug users (IDUs) in Kabul, Afghanistan, from June 2005 through June 2006. Study participants completed interviewer-administered questionnaires and underwent testing for HIV, antibody to HCV, and HBsAg. Overall prevalences of HIV, HCV, and HBsAg were 3.0% (95% confidence interval [CI] 1.7%–5.1%), 36.6% (95% CI 32.2%–41.0%), and 6.5% (95% CI 4.2%–8.7%), respectively (N = 464). Among male IDUs (n = 463), risky behavior, including sharing syringes (50.4%), paying women for sex (76.2%), and having sex with men or boys (28.3%), were common. Needle sharing, injecting for >3 years, and receiving injections from nonmedical providers were independently associated with increased risk for HCV infection. The high prevalence of risky behavior indicate that Kabul is at risk for an HIV epidemic. Scale-up of harm-reducing interventions is urgently needed. PMID:18252103

Viral hepatitis as an occupational disease in Poland.

In medical terms, occupational diseases are defined as health disorders specifically associated with the working environment of people and their occupational activity. From the medical and legal perspectives, the vast majority of European countries consider particular diseases to be of occupational origin if they are mentioned in the current list of occupational diseases and caused by exposure to factors in the working environment that are harmful to health. The aim of this study was to analyze the occurrence of cases of viral hepatitis certified as an occupational disease in Poland during 1979-2009. This article presents the medical, economic, and legal aspects of the epidemiology of hepatitis as an occupational disease in Poland. Publically available statistical data on certified occupational diseases in Poland and data contained in individual "occupational disease diagnosis cards" (based on data used in Poland statistical form), regarding certified cases of hepatitis among health care professionals, which were collected by the Department of Occupational Hygiene of the Polish Public Health Service, were analyzed in this study. In Poland, the highest number of cases of hepatitis certified as an occupational disease was observed in 1987. A gradual reduction in the number of cases of hepatitis as an occupational disease has been noted since then. Currently, hepatitis C as an occupational disease is certified more frequently than hepatitis B. In Poland, the number of women with hepatitis certified as an occupational disease is higher than that of men. However, among health care professionals, particularly nurses, this difference is insignificant because women outnumber the men. The existence of such a situation is due to the significant quantitative predominance of women over men among medical personnel, especially among nurses. Immunization of health care professionals against the hepatitis B virus (HBV), introduced in Poland in 1988, was an important factor

AIM: To evaluate the protective effect of inactivated hepatitis A vaccine (Healive®) against hepatitis A outbreak in an emergency vaccination campaign. METHODS: During an outbreak of hepatitis A in Honghe Town, Xiuzhou District, Jiaxing City, Zhejiang Province, two nonrandomized controlled trials were conducted in September 2006. The first trial was to vaccinate 108 anti-HAV negative individuals with close contacts of the patients from September with 1 dose of an inactivated hepatitis A vaccine, Healive®. The control group comprised of 115 individuals with close contacts of the patients before September. The second trial was to vaccinate 3365 primary and secondary school students who volunteered to receive a dose of Healive® and 2572 students who did not receive Healive® serving as its controls. An epidemiological survey was conducted to evaluate the protective efficacy of the vaccine. RESULTS: A total of 136 hepatitis A cases were reported during an outbreak that started in June, peaked in August and September, and ended after December of 2006. After a massive vaccination of school children in September, the number of cases declined significantly. No hepatitis A was detected in the 108 vaccinated individuals with close contacts of patients, whereas 4 cases of hepatitis A were found in the controls. The infection rate of hepatitis A was not significantly different in the individuals with close contacts of patients whether or not they received the vaccine (P = 0.122). No hepatitis A was detected in the 3365 students who received the vaccine, four cases of hepatitis A were found in the controls. The infection rate of students with or without vaccination was significantly different in the students who received the vaccine (0/3365 vs 4/2572, P = 0.035). The protective efficacy of the vaccine was 100%. CONCLUSION: Inactivated hepatitis A vaccine demonstrates a good protective effect against an outbreak of hepatitis A. PMID:18461664

Social capital strategies to enhance hepatitis C treatment awareness and uptake among men in prison.

Prisoner populations are characterized by high rates of hepatitis C (HCV), up to thirty times that of the general population in Australia. Within Australian prisons, less than 1% of eligible inmates access treatment. Public health strategies informed by social capital could be important in addressing this inequality in access to HCV treatment. Twenty-eight male inmates participated in qualitative interviews across three correctional centres in New South Wales, Australia. All participants had recently tested as HCV RNA positive or were receiving HCV treatment. Analysis was conducted with participants including men with experiences of HCV treatment (n=10) (including those currently accessing treatment and those with a history of treatment) and those who were treatment naïve (n=18). Social capital was a resourceful commodity for inmates considering and undergoing treatment while in custody. Inmates were a valuable resource for information regarding HCV treatment, including personal accounts and reassurance (bonding social capital), while nurses a resource for the provision of information and care (linking social capital). Although linking social capital between inmates and nurses appeared influential in HCV treatment access, there remained opportunities for increasing linking social capital within the prison setting (such as nurse-led engagement within the prisons). Bonding and linking social capital can be valuable resources in promoting HCV treatment awareness, uptake and adherence. Peer-based programmes are likely to be influential in promoting HCV outcomes in the prison setting. Engagement in prisons, outside of the clinics, would enhance opportunities for linking social capital to influence HCV treatment outcomes. © 2016 John Wiley & Sons Ltd.

The present study was undertaken to investigate the possible effects of Fe and trace element exposure on hepatic levels of retinoids in seven fish species. Concentrations of retinoids were measured in fish collected from a coastal lagoon in Brazil that receives effluents from an iron-ore mining and processing plant. Fish from nearby coastal lagoons were also included to assess possible differences related to chemical exposure. Results indicated considerable differences in hepatic retinoid composition among the various species investigated. The most striking differences were in retinol and derivative-specific profiles and in didehydro retinol and derivative-specific profiles. The Perciformes species Geophagus brasiliensis, Tilapia rendalli, Mugil liza, and Cichla ocellaris and the Characiforme Hoplias malabaricus were characterized as retinol and derivative-specific, while the Siluriformes species Hoplosternum littorale and Rhamdia quelen were didehydro retinol and derivative-specific fish species. A negative association was observed between Al, Pb, As, and Cd and hepatic didehydro retinoid levels. Fish with higher levels of hepatic Fe, Cu, and Zn showed unexpectedly significant positive correlations with increased hepatic retinol levels. This finding, associated with the positive relationships between retinol and retinyl palmitate with lipid peroxidation, may suggest that vitamin A is mobilized from other tissues to increase hepatic antioxidant levels for protection against oxidative damage. These data show significant but dissimilar associations between trace element exposure and hepatic retinoid levels in fish species exposed to iron-ore mining and processing effluents, without apparent major impacts on fish health and condition.

Regarding SOS in rhabdomyosarcoma patients who received conventional chemotherapy, the doses of chemotherapeutic agents are associated with the development of SOS. Several cases of SOS in rhabdomyosarcoma patients after receiving chemotherapy with escalated doses of cyclophosphamide have been reported. Here, we report on a 9-year-old female with rhabdomyosarcoma who developed severe SOS after receiving chemotherapy consisting of vincristine, actinomycin-D, and a moderate dose of cyclophosphamide. She was treated successfully with defibrotide without sequelae to the liver.

Since 2016, an increase in the number of hepatitis A cases affecting mainly men who have sex with men (MSM) has been reported in low endemic countries in Europe. We calculated the attack rate in Lyon, France, in populations considered at high-risk: HIV-infected MSM and HIV-negative MSM receiving HIV pre-exposure prophylaxis (PrEP). In these populations, high level of immunity did not prevent the outbreak, indicating that vaccination should be reinforced, particularly in younger individuals.

Antibody-mediated pure red cell aplasia (PRCA) has been primarily observed in patients with chronic kidney disease treated with an erythropoiesis-stimulating agent (ESA); only a few anecdotal cases have been reported in other patient populations. We searched the Amgen Global Safety Adverse Event Database and identified 14 patients with hepatitis C who developed severe anemia, anti-erythropoietin antibodies, and bone marrow biopsy-proven PRCA, while receiving interferon therapy (with or without ribavirin) and an ESA. During the follow-up period and after ESA treatment stopped, 11 patients no longer required transfusions and 3 did. Analysis of antibody isotypes showed that, contrary to reports of patients with chronic kidney disease, immunoglobulin G1 was the predominant isotype rather than immunoglobulin G4 (immunoglobulin G4 was detected in only 1 of 6 patients). Epitope mapping showed the anti-erythropoietin antibodies bound domains required for receptor binding. Therefore, the potential benefits of ESA therapy must be weighed against the risk for PRCA in patients with hepatitis C who are receiving treatment with interferon and ribavirin.

Hepatitis A is an acute, usually self-limiting infection of the liver caused by a virus known as hepatitis A virus (HAV). Humans are the only reservoir of the virus; transmission occurs primarily through the fecal-oral route and is closely associated with poor sanitary conditions. The virus has a worldwide distribution and causes about 1.5 million cases of clinical hepatitis each year. The risk of developing symptomatic illness following HAV infection is directly correlated with age. As many 85% of children below 2 y and 50% of those between 2-5 y infected with HAV are anicteric, and among older children and adults, infection usually causes clinical disease, with jaundice occurring in more than 70% of cases. The infection is usually self-limiting with occasional fulminant hepatic failure and mortality. In most developing countries in Asia and Africa, hepatitis A is highly endemic such that a large proportion of the population acquires immunity through asymptomatic infection early in life. HAV is endemic in India; most of the population is infected asymptomatically in early childhood with life-long immunity. Several outbreaks of hepatitis A in various parts of India have been recorded in the past decade such that anti-HAV positivity varied from 26 to 85%. Almost 50% of children of ages 1-5 y were found to be susceptible to HAV. Any one of the licensed vaccines may be used since all have nearly similar efficacy and safety profiles (except for post-exposure prophylaxis / immunocompromised patients, where only inactivated vaccines may be used). Two doses 6 mo apart are recommended for all vaccines. All Hepatitis A vaccines are licensed for use in children aged 1 y or older. However in the Indian scenario, it is preferable to administer the vaccines at age 18 mo or more when maternal antibodies have completely declined. Vaccination at this age is preferable to later since it is easier to integrate with the existing schedule, protects those who have no antibodies, and

In order to enhance screening and preventive strategies, this study investigated the seroprevalence of hepatitis A, B, and C in the general adult urban population and in subgroups. In 2004, sera from 1,364 adult residents of Amsterdam were tested for viral markers. Sociodemographic characteristics were collected using a standardized questionnaire. For hepatitis A, 57.0% was immune. Of first-generation immigrants from Turkey and Morocco, 100% was immune. Of all Western persons and second-generation non-Western immigrants, approximately half was still susceptible. For hepatitis B, 9.9% had antibodies to hepatitis B core antigen (anti-HBc) and 0.4% had hepatitis B surface antigen. Anti-HBc seroprevalences were highest among first-generation immigrants from Surinam, Morocco, and Turkey, and correlated with age at the time of immigration, and among men with a sexual preference for men. Seroprevalence among second-generation immigrants was comparable to Western persons. The seroprevalence of hepatitis C virus antibodies was 0.6%. In conclusion, a country with overall low endemicity for viral hepatitis can show higher endemicity in urban regions, indicating the need for differentiated regional studies and prevention strategies. More prevention efforts in cities like Amsterdam are warranted, particularly for hepatitis A and B among second-generation immigrants, for hepatitis B among men with a sexual preference for men, and for hepatitis C. Active case finding strategies are needed for both hepatitis B and C. (c) Wiley-Liss, Inc.

The experience of hepatitis C treatment for people with a history of mental health problems: An interpretative phenomenological analysis.

This qualitative study explores the experience of hepatitis C virus treatment for people with pre-existing mental health problems within a large city hospital. Four men and four women with pre-existing mental health problems who had received hepatitis C virus treatment took part in semi-structured interviews which were analysed using interpretative phenomenological analysis. A central theme of 'Self, stigma and change' was identified which interlinked with three other main themes of 'Coping and responding to treatment', 'Connectedness to others' and 'The impact of information'. These themes and their sub-themes are discussed in relation to existing literature and clinical practice guidelines. © The Author(s) 2013.

Since 2016, an increase in the number of hepatitis A cases affecting mainly men who have sex with men (MSM) has been reported in low endemic countries in Europe. We calculated the attack rate in Lyon, France, in populations considered at high-risk: HIV-infected MSM and HIV-negative MSM receiving HIV pre-exposure prophylaxis (PrEP). In these populations, high level of immunity did not prevent the outbreak, indicating that vaccination should be reinforced, particularly in younger individuals. PMID:29208161

Hepatitis A virus (HAV) is one of the most common infectious etiologies of acute hepatitis worldwide. The virus is known to be transmitted fecal-orally, resulting in symptoms ranging from asymptomatic infection to fulminant hepatitis. HAV can also be transmitted through oral-anal sex. Residents from regions of low endemicity for HAV infection often remain susceptible in their adulthood. Therefore, clustered HAV infections or outbreaks of acute hepatitis A among men who have sex with men and injecting drug users have been reported in countries of low endemicity for HAV infection. The duration of HAV viremia and stool shedding of HAV may be longer in human immunodeficiency virus (HIV)-positive individuals compared to HIV-negative individuals with acute hepatitis A. Current guidelines recommend HAV vaccination for individuals with increased risks of exposure to HAV (such as from injecting drug use, oral-anal sex, travel to or residence in endemic areas, frequent clotting factor or blood transfusions) or with increased risks of fulminant disease (such as those with chronic hepatitis). The seroconversion rates following the recommended standard adult dosing schedule (2 doses of HAVRIX 1440 U or VAQTA 50 U administered 6-12 mo apart) are lower among HIV-positive individuals compared to HIV-negative individuals. While the response rates may be augmented by adding a booster dose at week 4 sandwiched between the first dose and the 6-mo dose, the need of booster vaccination remain less clear among HIV-positive individuals who have lost anti-HAV antibodies.

2009-10-01

To examine the relationship between dietary fiber and the risk of type 2 diabetes in older men and the role of hepatic and inflammatory markers. The study was performed prospectively and included 3,428 nondiabetic men (age 60-79 years) followed up for 7 years, during which there were 162 incident cases of type 2 diabetes. Low total dietary fiber (lowest quartile < or =20 g/day) was associated with increased risk of diabetes after adjustment for total calorie intake and potential confounders (relative risk -1.47 [95% CI 1.03-2.11]). This increased risk was seen separately for both low cereal and low vegetable fiber intake. Dietary fiber was inversely associated with inflammatory markers (C-reactive protein, interleukin-6) and with tissue plasminogen activator and gamma-glutamyl transferase. Adjustment for these markers attenuated the increased risk (1.28 [0.88-1.86]). Dietary fiber is associated with reduced diabetes risk, which may be partly explained by inflammatory markers and hepatic fat deposition.

To understand the human immunodeficiency virus (HIV) infection status and syphilis prevalence among men who have sex with men (MSM) receiving voluntary counseling and testing appointed through a web-based registering system and related factors. The MSM receiving web appointed HIV counseling and testing from 2011 to 2012 in Guangzhou were recruited and a questionnaire survey was conduct among them to obtain the information about their demographic characteristics and sexual behavior. Binary and multivariate logistic regression model were used to identify the factors associated with HIV infection or syphilis prevalence. A total of 4,904 MSM were enrolled in the study, the average age of the MSM was (28.77±7.24) years, and 70.3% of them had high education level; the unmarried MSM accounted for 72.7%. The HIV infection rate and syphilis prevalence were 8.7% and 4.4% respectively. The co-infection rate of HIV and Treponema pallidum was 1.2% (59/4 904). About one in three MSM did not use condom at latest homosexual behavior, 43.5% did not use condoms at each homosexual behavior in the past three months. Lower education level, occupation (worker or farmer), non-consistent condom use at each sex with men in the past three months, receiving HIV test or not and Treponema pallidum infection were associated with HIV infection. Age≥40 years, lower education level, multi male sex partners in the past three months and HIV infection were associated with Treponema pallidum infection. MSM receiving web appointed HIV counseling and testing had high prevalence of risk behaviors and high HIV infection rate, but had low previous HIV testing rate. It is necessary to strengthen the promotion of HIV test through web based appointment and conduct target behavior intervention in older MSM with lower education level.

Non-alcoholic fatty liver disease is common in human immunodeficiency virus, but there are no approved therapies. The aim of this open-label proof-of-concept study was to determine the effect of the mineralocorticoid receptor antagonist eplerenone on hepatic fat in human immunodeficiency virus-infected patients with hepatic fat ≥5% by magnetic resonance spectroscopy. Five subjects received eplerenone (25 mg daily × 1 week followed by 50 mg daily × 23 weeks). Laboratory tests were done at each visit, and the primary endpoint, change in hepatic fat content, was determined by MRI spectroscopy at baseline and week 24. The study was stopped early after observing unexpected significant increases in hepatic fat at week 24 (mean increase 13.0 ± 7.3%, P = .02). The increases in steatosis were accompanied by a tendency for transaminase values to decrease (alanine aminotransferase mean change -14 ± 16 IU/L, P = .14). There were no consistent changes in other metabolic parameters or blood pressure. Repeat assessment of hepatic steatosis 1-2 months after stopping study medication revealed improvements in steatosis towards baseline values. The unexpected observation of increased hepatic steatosis with the administration of eplerenone led to early termination of the investigation. While limited because of the small number of participants and the open-label design, this study provides data to suggest that mineralocorticoid receptor antagonism with eplerenone may not be an effective approach to treat hepatic steatosis in human immunodeficiency virus or the general population. Additional research is needed to determine the pathophysiological mechanism behind these unanticipated observations. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

In patients with chronic hepatitis C (CHC), superinfection with hepatitis A (HAV) or B (HAB) viruses is associated with increased morbidity and mortality. The seroconversion rate of these patients following vaccination is considered to be lower than in healthy subjects. To evaluate the response to HAV and HBV vaccination in children with CHC. Thirty patients with CHC aged from 7.3 to 18 years were compared with 50 healthy age-, gender- and body-mass-index-matched controls. Post-vaccination serological evaluation was performed 1 month after the last dose of primary vaccination, 1 month after the booster dose and once a year during follow-up. Twenty-two patients received hepatitis A vaccine and response rate was 95.4%. Thirty patients received hepatitis B vaccine and 80% responded (hepatitis Bs titres ≥10 mIU/ml). Thirty-five controls received hepatitis A vaccine and protective anti-HAV antibodies developed in all. All of the controls were vaccinated against hepatitis B virus and 90% responded. After the whole vaccination series, overall seroprotection rates were 86% in patients and 96% in controls. No significant reduction in antibody response was observed in patients or controls during 8-years follow-up. The rate of seroconversion to the HBV vaccine is lower in patients with CHC than in healthy controls but response to HAV is adequate.

Burden of Chronic Viral Hepatitis and Liver Cirrhosis in Brazil - the Brazilian Global Burden of Disease Study.

Data on epidemiology of liver diseases in Brazil is scarce. This study aimed to estimate the burden of chronic viral hepatitis and liver cirrhosis in the country. The indicator used was disability-adjusted life year (DALY), a sum of years of life lost due to premature mortality (YLL) and years lived with disability (YLD). Liver cirrhosis was analyzed in etiologic categories and cirrhosis of viral origin was considered part of the burden of chronic hepatitis. There were 57,380 DALYs (30.3 per 100,000 inhabitants) attributable to chronic hepatitis B and cirrhosis due to hepatitis B, with 41,262 DALYs in men. Most burden was caused by YLL (47,015 or 24.8/100,000) rather than YLD (10,365 or 5.5/100,000). Chronic hepatitis C and cirrhosis due to hepatitis C were responsible for 207,747 DALYs (109.6/100,000), of which 137,922 were YLL (72.7/100,000) and 69,825 (36.8/100,000) were YLD, with a higher proportion of DALYs in men (73.9%). Cirrhosis due to alcohol or other causes had a total of 536,169 DALYs (1,4% of total DALYs in Brazil), with 418,272 YLL (341,140 in men) and 117,897 YLD (97,965 in men). Highest DALYs' rates occurred at ages 60-69 in chronic hepatitis and at ages 45-59 in cirrhosis due to alcohol or other causes. Chronic viral hepatitis and liver cirrhosis are responsible for a significant burden in Brazil, affecting mainly men and individuals still in their productive years. Most burden is related to non-viral causes of cirrhosis, with a major contribution of alcohol.

Emerging viral STIs among HIV-positive men who have sex with men: the era of hepatitis C virus and human papillomavirus.

PubMed

van de Laar, Thijs Jw; Richel, Olivier

2017-08-01

The number of infectious disease outbreaks and the number of unique pathogens responsible have significantly increased since the 1980s. HIV-positive men who have sex with men (MSM) are a vulnerable population with regards to the introduction, spread and clinical consequences of (newly introduced) STIs. After the introduction of combination antiretroviral treatment (cART), the incidence of sexually acquired hepatitis C virus (HCV) infection and human papillomavirus (HPV)-induced anal cancers have significantly increased among HIV-positive MSM. The introduction and expansion of HCV is the result of increased sexual risk behaviour and sexually acquired mucosal trauma within large interconnected networks of HIV-positive MSM in particular. With the availability of cART, postexposure and pre-exposure prophylaxis (PEP and PrEP) and direct-acting antivirals (DAAs) for HCV, less concern for HIV and HCV might require a new approach to develop effective behavioural intervention strategies among MSM. The marked rise in HPV-induced anal cancers can be ascribed to the long-term immunologic defects in an ageing population affected by HIV. More evidence with regards to effective treatment options for anal dysplastic lesions and the usefulness of anal malignancy screening programmes is urgently needed. Most anal cancers in the future generation of HIV-positive MSM could be prevented with the inclusion of boys in addition to girls in current HPV vaccination programmes.

An outbreak of hepatitis caused by hepatitis E virus (HEV) in Abbottabad, Pakistan was traced to fecal contamination of a water system. Of 109 men hospitalized with hepatitis, 104 (95%) had serologic evidence of acute hepatitis E (IgM antibody to HEV [anti-HEV]), three (3%) probably had acute hepatitis E (high titers of IgG anti-HEV without IgM), and two had acute hepatitis A. Among a subset of 44 men with acute hepatitis E from whom three serum specimens were obtained over a four-month period, the anti-HEV IgG geometric mean titers (GMTs) decreased from 1,519 during the outbreak to 657 at four months. The IgM anti-HEV was detected in 40 (91%) of 44 sera obtained at admission (GMT = 533 during acute disease), but in only six (14%) four months later. The prevalence of anti-HEV in this population before the outbreak was estimated to be 30%. The presence of IgG anti-HEV appeared to protect against clinical hepatitis or development of serologic evidence of new infection with HEV. This is the second major epidemic of hepatitis E in the Pakistani military confirmed by an anti-HEV enzyme-linked immunosorbent assay (ELISA). Evidence that pre-existing antibody as measured by this ELISA protects against disease is important for assessment of vaccine development.

Isolated Hepatic Metastasis from Prostate Carcinoma.

Worldwide, prostate cancer is considered the second most common cancer in men. Most common sites for metastatic disease are lymph nodes and bones. However, isolated liver metastasis from prostate cancer is rare. We present a 75 year-old male with prostate adenocarcinoma diagnosed 7 years ago. With rising PSA, he underwent imaging and found to have isolated hepatic metastasis. After left hepatic lobectomy, his PSA dramatically decreased to < 0.01. Physicians should be aware of isolated hepatic metastasis in patients with prostate cancer. Metastasectomy should be considered in such case, and combined medical and surgical approach may prolong the overall survival.

Effect of Testosterone Administration on Liver Fat in Older Men With Mobility Limitation: Results From a Randomized Controlled Trial

PubMed Central

2013-01-01

Background. Androgen receptor (AR) knockout male mice display hepatic steatosis, suggesting that AR signaling may regulate hepatic fat. However, the effects of testosterone replacement on hepatic fat in men are unknown. The aim of this study was to determine the effects of testosterone administration on hepatic fat in older men with mobility limitation and low testosterone levels who were participating in a randomized trial (the Testosterone in Older Men trial). Methods. Two hundred and nine men with mobility limitation and low total or free testosterone were randomized in the parent trial to either placebo or 10-g testosterone gel daily for 6 months. Hepatic fat was determined by magnetic resonance imaging in 73 men (36 in placebo and 37 in testosterone group) using the volumetric method. Insulin sensitivity (homeostatic model assessment–insulin resistance) was derived from fasting glucose and insulin. Results. Baseline characteristics were similar between the two groups, including liver volumes (1583±363 in the testosterone group vs 1522±271mL in the placebo group, p = .42). Testosterone concentrations increased from 250±72 to 632±363ng/dL in testosterone group but did not change in placebo group. Changes in liver volume during intervention did not differ significantly between groups (p = .5) and were not related to on-treatment testosterone concentrations. The change in homeostatic model assessment–insulin resistance also did not differ significantly between groups and was not related to either baseline or change in liver fat. Conclusion. Testosterone administration in older men with mobility limitation and low testosterone levels was not associated with a reduction in hepatic fat. Larger trials are needed to determine whether testosterone replacement improves liver fat in men with nonalcoholic hepatic steatosis. PMID:23292288

Our aim was to retrospectively analyze the location of confluent hepatic fibrosis in relation to the portal and hepatic venous anatomy using multidetector computed tomography (CT) and to clarify the influence of the hepatic venous drainage on confluent fibrosis. The study population consisted of 879 patients diagnosed with cirrhosis: 539 men and 340 women (65.9 ± 10.6 years) and 633 with Child-Pugh class A, 161 with class B, and 85 with class C. The cause of cirrhosis was hepatitis C (n = 528) and hepatitis B (n = 122) virus infection, alcoholism (n = 114), and others (n = 115). The confluent fibrosis was diagnosed using CT images according to previous reports and statistically analyzed (p < 0.05). Thirty-five confluent fibrosis lesions in 30 patients (3.4 %) were identified. The predictive factors were alcoholic cirrhosis [odds ratio (OR), 7.25; p < 0.0001], Child-Pugh class C (OR, 6.95; p < 0.0001), and Child-Pugh class B (OR, 2.91; p < 0.0023). Confluent fibrosis was most frequently seen in the middle hepatic venous drainage area (n = 21) or at the boundary between the medial and anterior segments (n = 17), and each distribution of the location of confluent fibrosis was significantly unequal (p < 0.0001). Confluent fibrosis was most commonly located in the middle hepatic venous drainage area.

Coffee or caffeine has been proposed to protect against hepatic fibrosis, but few data are available on their effects in patients with chronic hepatitis C virus (HCV) infection. We conducted a cross-sectional study of veterans with chronic HCV infection to evaluate the association between daily intake of caffeinated and decaffeinated coffee, tea, and soda, and level of hepatic fibrosis, based on the FibroSURE test (BioPredictive, Paris, France) (F0-F3, mild [controls] vs. F3/F4-F4, advanced). Models were adjusted for multiple potential confounders including age, alcohol abuse, and obesity. Among 910 patients with chronic HCV infection, 98% were male and 38% had advanced hepatic fibrosis. Daily intake of caffeinated coffee was higher among controls than patients with advanced fibrosis (1.37 vs. 1.05 cups/d; P = .038). In contrast, daily intake of caffeinated tea (0.61 vs. 0.56 cups/d; P = .651) or soda (1.14 vs. 0.95 cans/d; P = .106) did not differ between the groups. A higher percentage of controls (66.0%) than patients with advanced fibrosis (57.9%) consumed 100 mg or more of caffeine daily from all sources (P = .014); controls also received a larger proportion of their caffeine from coffee (50.2% vs. 43.0%; P = .035). Hepatoprotective effects of an average daily intake of 100 mg or more of caffeine (adjusted odds ratio, 0.71; 95% confidence interval, 0.53-0.95; P = .020) and 1 cup or more of caffeinated tea by non-coffee drinkers (adjusted odds ratio, 0.56; 95% confidence interval, 0.34-0.94; P = .028) persisted after adjustment for confounders, including insulin resistance. A modest daily caffeine intake (as little as 100 mg) may protect against advanced hepatic fibrosis in men with chronic HCV infection. Additional research is needed to confirm these findings in women and in people with other chronic liver diseases. Copyright © 2015 AGA Institute. Published by Elsevier Inc. All rights reserved.

Acute hepatitis C in an HIV-infected patient: a case report and review of literature.

PubMed

Driver, Todd H; Terrault, Norah; Saxena, Varun

2013-05-01

With the decrease in transmission via transfusions and injection drug use, acute symptomatic hepatitis C is infrequently seen in developed countries. We report a case of a human immunodeficiency virus (HIV)-infected adult who presented with abdominal pain. His alanine aminotransferase was greater than sixty times the upper limit of normal without any evidence on examination of fulminant hepatic failure. His workup revealed an elevated hepatitis C viral level with a negative hepatitis C antibody. He was discharged once his liver function tests improved. As an outpatient, he had a recurrent bout of symptoms with an elevation of his alanine aminotransferase and hepatitis C viral levels that promoted anti-hepatitis C virus treatment. This case illustrates the importance of considering acute hepatitis C as a cause of acute hepatitis in HIV-infected men who have sex with men. While patients with acute symptomatic hepatitis C generally have a higher rate of spontaneous viral clearance compared to those with an insidious acute infection, most still progress to chronic hepatitis C infection, and patients with HIV coinfection carry a higher risk of progression to chronic disease.

High rates of hepatitis C virus (HCV) reinfections among HIV-infected men who have sex with men (MSM) following clearance of a primary infection suggest absence of protective immunity. Here, we investigated the incidence of HCV super and reinfections in 85 HIV-infected MSM with incident HCV infection. Serial sequencing of a fragment of NS5B and the HCV envelope was used to longitudinally characterize the virus. If the primary genotype was still present at the most recent viremic time point, as indicated by the NS5B sequence analysis, serial envelope 2/hypervariable region 1 (E2/HRV1) sequence analysis was performed to distinguish a new infection with the same genotype (clade switch) from intrahost evolution. Incidence rate and cumulative incidence of secondary infections were estimated, and the effect of the primary genotype (1a versus non1) on the risk of acquiring a second infection with the same genotype was determined using Cox proportional-hazards analysis. Among 85 patients with a median follow-up of 4.8 years, incidence rate of secondary infections was 5.39 cases/100 person-years (95% confidence interval 3.34-8.26). Cumulative incidence of genotype switches was markedly higher than the cumulative incidence of clade switches (26.7 versus 4.8% at 5 years, respectively). In patients with HCV-1a as primary infection, the risk for acquiring another HCV-1a infection was reduced compared to those with a primary non-HCV-1a subsequently acquiring HCV-1a (hazard ratio 0.25, 95% confidence interval 0.07-0.93). Risk of acquiring a secondary infection with the primary genotype was strikingly reduced compared with the risk of acquiring a secondary infection with a different genotype.

Sexual transmission of Hepatitis C virus (HCV) in men who have sex with men (MSM) and its interaction with HIV status, sexually transmitted infections and sexual behaviour is poorly understood. We assessed the incidence and predictors of HCV infection in HIV positive MSM. The electronic medical record and laboratory results from HIV positive MSM in care at a large urban public specialist HIV clinic embedded in a sexual health centre in Melbourne Australia were collected. Patients with two or more HCV antibody tests between January 2008 and March 2016 and with no record of injecting drug use were included. The HCV exposure intervals were the periods between a negative HCV test and the next HCV test. We compared HCV exposure intervals temporally associated with and without newly acquired syphilis or anorectal chlamydia. HCV exposure intervals were also categorised as being before or after HIV virological suppression and by most recent and nadir CD4 cell count. Thirty seven new HCV infections were diagnosed in 822 HIV positive MSM with no history of injecting drug use over 3114 person years (PY) of follow-up. Mean age was 43.1 years (±12.5) and mean CD4 cell count nadir was 362 cells/uL (±186). The incidence of HCV infection in the study population was 1.19/100PY (0.99-1.38). The incidence in exposure periods temporally close to new syphilis infection was 4.72/100PY (3.35-6.08) and to new anorectal chlamydia infection was 1.37/100PY (0.81-1.93). The incidence in men without supressed viral load was 3.19/100PY (1.89-4.49). In the multivariate Cox regression analysis only younger age (aHR 0.67 (0.48-0.92)), exposure periods temporally associated to new syphilis infection (aHR 4.96 (2.46-9.99)) and higher CD4 cell count nadir (aHR 1.26 per 100 cells/uL (1.01-1.58)) were associated with increased risk of HCV infection. During the study period the incidence of syphilis increased dramatically but the incidence of HCV infection remained the same. Incidence of HCV

The majority of men are insufficiently active. Men's tendencies to participate in risky behaviors and their inactivity likely contribute to their increased risk of morbidity and mortality. Physical activity decreases the risk of developing many chronic diseases and may be an optimal behavior to target in men's health interventions. However, educational resources promoting physical activity for men are lacking. To address this gap, we tested the efficacy of messages based upon the Extended Parallel Process Model (EPPM; Witte, 1992) to increase men's physical activity intentions and behaviors. Men who were not meeting physical activity guidelines (n = 611) were randomly assigned to read high or low efficacy physical activity messages paired with high or no health risk information. Participants read four brief messages on four consecutive days. Intentions were assessed at baseline and the first follow-up (Day 5). Manipulation check measures were assessed at Day 5. Behavior was assessed at baseline and the second follow-up (Day 14). Overall, the messages had small sized effects. A completer analysis revealed that although men's intentions to be active increased over the course of the study regardless of the messages they received, only men who received risk information significantly increased their physical activity. Men who received low efficacy and risk information were less likely to meet the physical activity guidelines at Day 14 than men who only received low efficacy information. From these results, we suggest preliminary recommendations for the development of physical activity messages for men and areas for future EPPM-based research.

Hepatitis A (HA) has been a vaccine-preventable disease since 1995. In Catalonia, a universal combined hepatitis A+B vaccination program of preadolescents was initiated at the end of 1998. However, outbreaks are reported each year and post-exposure prophylaxis (PEP) with hepatitis A virus (HAV) vaccine or immunoglobulin (IG) is recommended to avoid cases. The aim of this study was to assess the effectiveness of HAV vaccine and IG in preventing hepatitis A cases in susceptible exposed people. A retrospective cohort study of contacts of HA cases involved in outbreaks reported in Catalonia between January 2006 and December 2012 was made. The rate ratios and 95% confidence intervals (CI) of HA in susceptible contacts receiving HAV or IG versus those without PEP were calculated. There were 3550 exposed persons in the outbreaks studied: 2381 received one dose of HAV vaccine (Hepatitis A or hepatitis A+B), 190 received IG, and 611 received no PEP. 368 exposed subjects received one dose of HAV vaccine and IG simultaneously and were excluded from the study. The effectiveness of PEP was 97.6% (95% CI 96.2-98.6) for HAV vaccine and 98.3% (95% CI 91.3-99.9) for IG; the differences were not statistically significant (p = 0.36). The elevated effectiveness of HAV vaccination for PEP in HA outbreaks, similar to that of IG, and the long-term protection of active immunization, supports the preferential use of vaccination to avoid secondary cases.

Objectives. We assessed the effect on trends in hepatitis A incidence of the 1996 recommendation for routine hepatitis A vaccination of American Indian/Alaska Native (AIAN) children. Methods. We examined trends in hepatitis A incidence among AIAN peoples during 1990–2001 and vaccination coverage levels among children on the largest American Indian reservation. Results. Hepatitis A rates among AIANs declined 20-fold during 1997–2001. Declines in hepatitis A incidence occurred among AIANs in reservation and metropolitan areas. Among 1956 children living on the Navajo Nation whose medical records were reviewed, 1508 (77.1%) had received at least one dose of hepatitis A vaccine, and 1020 (52.1%) had completed the vaccine series. Conclusions. Hepatitis A rates among AIAN peoples have declined dramatically coincident with implementation of routine hepatitis A vaccination of AIAN children. PMID:15249305

Chronic Liver Disease (CLD) has been shown to have an adverse impact on bone health. Hepatitis-B related CLD and its treatment with tenofovir may have additional effects on skeleton. To study the impact of HBV related CLD and its treatment with Tenofovir on bone health in Indian subjects. This cross sectional study included men (18-60 years) and comprised of three groups: Group-1 was treatment naïve HBV related CLD ( n  = 79), Group-2 those with HBV related CLD on tenofovir for at least 1 year ( n  = 136), Group-3 age, sex and Body Mass Index (BMI) matched healthy controls ( n  = 58). Bone biochemistry and Bone Mineral Density (BMD) at spine, Femoral Neck (FN) and forearm were studied. Independent t -test or ANOVA was used to compare the means of continuous variables and chi-square test for categorical variables. Multiple logistic regression was used to assess the factors causing Low Bone Mass (LBM) at FN. A significantly greater proportion ( P  < 0.05) of patients (40%) with CLD (group 1 and group 2) had vitamin D deficiency (<20 ng/ml) in comparison with control group (22%). The mean serum C-Terminal telopeptide was significantly higher ( P  < 0.05) and the mean BMD was significantly lower ( P  < 0.05) in subjects with HBV related CLD than controls. The prevalence of LBM was higher in group 1 at the spine (31%) and forearm (18.4%) when compared to controls (8.1% and 7.8% respectively) ( P  < 0.05). The proportion of patients with LBM at FN was highest in group 2 (12.3%) compared to those in group 1 (8%) and group 3 (4%) ( P  < 0.05). Advanced age, low BMI, and high viral load (>10,000 IU/ml) emerged as significant risk factors for LBM at FN. The impact of hepatitis-B related CLD as well as its treatment on bone health is significant. Bone health need to be periodically evaluated in these subjects especially in older men who are lean and have a higher viral load.

Prognostic factors in men with penile squamous cell carcinoma (PSCC) receiving systemic therapy are unknown. A prognostic classification system in this disease may facilitate interpretation of outcomes and guide rational drug development. We performed a retrospective analysis to identify prognostic factors in men with PSCC receiving first-line systemic therapy for advanced disease. Individual patient level data were obtained from 13 institutions to study prognostic factors in the context of first-line systemic therapy for advanced PSCC. Cox proportional hazards regression analysis was conducted to examine the prognostic effect of these candidate factors on progression-free survival (PFS) and overall survival (OS): age, stage, hemoglobin, neutrophil count, lymphocyte count, albumin, site of metastasis (visceral or nonvisceral), smoking, circumcision, regimen, ECOG performance status (PS), lymphovascular invasion, precancerous lesion, and surgery following chemotherapy. The effect of different treatments was then evaluated adjusting for factors in the prognostic model. The study included 140 eligible men. Mean age across all men was 57.0 years. Among them, 8.6%, 21.4%, and 70.0% of patients had stage 2, 3, and 4 diseases, respectively; 40.7% had ECOG PS ≥ 1, 47.4% had visceral metastases, and 73.6% received cisplatin-based chemotherapy. The multivariate model of poor prognostic factors included visceral metastases (P<0.001) and ECOG PS ≥ 1 (P<0.001) for both PFS and OS. A risk stratification model constructed with 0, 1, and both poor prognostic factors was internally validated and demonstrated moderate discriminatory ability (c-statistic of 0.657 and 0.677 for OS and PFS, respectively). The median OS for the entire population was 9 months. Median OS was not reached, 8, and 7 months for those with 0, 1, and both risk factors, respectively. Cisplatin-based regimens were associated with better OS (P = 0.017) but not PFS (P = 0.37) compared with noncisplatin

The authors previously reported a fall in hepatic glucose output (HGO) during sleep accompanied by reductions in glucose utilization (Rd) and free fatty acids (FFAs). This study was undertaken to determine the potential role of changes in Rd and FFA on HGO in nondiabetic men. To determine if the fall in HGO during sleep could be reversed by FFA elevation, seven nondiabetic men underwent (3-3H)glucose infusions from 2200 to 0800, with heparin (90 mU.kg-1.min-1) added at 0200. Glucose appearance (Ra) fell from 11.7 {plus minus} 1.1 at 2430 to 8.9 {plus minus} 0.8 mumol.kg-1.min-1 (P less than 0.05) at 0200.more » The fall in Ra was associated with decreases in FFA (0.57 {plus minus} 0.10 to 0.48 {plus minus} 0.07 mM) and glycerol (0.08 {plus minus} 0.01 to 0.06 {plus minus} 0.01 mM). Infusion of heparin significantly increased FFA and glycerol (1.09 {plus minus} 0.21 and 0.11 {plus minus} 0.01 mM, respectively, P less than 0.01) and resulted in a significant fall in plasma alanine, suggesting that gluconeogenesis had been increased. However, rates of glucose turnover were indistinguishable from overnight studies without heparin. In additional studies (n = 6), intralipid and heparin-induced FFA elevation (from 0.61 {plus minus} 0.07 to 0.95 {plus minus} 0.05 mM, P less than 0.01) stimulated gluconeogenesis ((U-14C)alanine to glucose) twofold (188 {plus minus} 22% increase compared to 114 {plus minus} 6% in saline control studies, P less than 0.01). However, despite increasing gluconeogenesis, overall HGO did not change (10.6 {plus minus} 0.5 vs. 10.7 {plus minus} 0.6 mumol.kg-1.min-1) during lipid infusion.« less

Non-alcoholic fatty liver disease and its precursor hepatic steatosis is common in obesity and type-2 diabetes and is associated with cardiovascular disease (CVD). Men with type-2 diabetes and/or CVD have a high prevalence of testosterone deficiency. Testosterone replacement improves key cardiovascular risk factors. The effects of testosterone on hepatic steatosis are not fully understood. Testicular feminised (Tfm) mice, which have a non-functional androgen receptor (AR) and very low serum testosterone levels, were used to investigate testosterone effects on high-cholesterol diet-induced hepatic steatosis. Hepatic lipid deposition was increased in Tfm mice and orchidectomised wild-type littermates versus intact wild-type littermate controls with normal androgen physiology. Lipid deposition was reduced in Tfm mice receiving testosterone treatment compared to placebo. Oestrogen receptor blockade significantly, but only partially, reduced the beneficial effects of testosterone treatment on hepatic lipid accumulation. Expression of key regulatory enzymes of fatty acid synthesis, acetyl-CoA carboxylase alpha (ACACA) and fatty acid synthase (FASN) were elevated in placebo-treated Tfm mice versus placebo-treated littermates and Tfm mice receiving testosterone treatment. Tfm mice on normal diet had increased lipid accumulation compared to littermates but significantly less than cholesterol-fed Tfm mice and demonstrated increased gene expression of hormone sensitive lipase, stearyl-CoA desaturase-1 and peroxisome proliferator-activated receptor-gamma but FASN and ACACA were not altered. An action of testosterone on hepatic lipid deposition which is independent of the classic AR is implicated. Testosterone may act in part via an effect on the key regulatory lipogenic enzymes to protect against hepatic steatosis. Copyright © 2014 Elsevier Inc. All rights reserved.

A decline of hepatitis C virus (HCV) antibody titers (anti-HCV), ultimately resulting in seroreversion, has been reported following clearance of viremia in both acute and chronic HCV infection. However, frequency of seroreversion remains unknown in human immunodeficiency virus (HIV)/HCV-coinfected patients. We describe anti-HCV dynamics among HIV-infected men who have sex with men (MSM) following acute HCV infection and reinfection. Primary acute HCV infection was assumed when a subject was anti-HCV negative prior to the first positive HCV RNA test. Anti-HCV was measured at least annually in 63 HIV-infected MSM, with a median follow-up of 4.0 years (interquartile range [IQR], 2.5-5.7 years). Time from HCV infection to seroconversion, and from seroconversion to seroreversion, was estimated using the Kaplan-Meier method. Longitudinal anti-HCV patterns were studied using a random-effects model to adjust for repeated measures. Median time from HCV infection to seroconversion was 74 days (IQR, 47-125 days). Subjects who cleared HCV RNA (n = 36) showed a significant decrease in anti-HCV levels (P < .001). Among 31 subjects with sustained virologic response (SVR), anti-HCV became undetectable during follow-up in 8; cumulative incidence of seroreversion within 3 years after seroconversion was 37% (95% confidence interval, 18%-66%). Eighteen subjects became reinfected during follow-up; this coincided with a subsequent increase in anti-HCV reactivity. A decline of anti-HCV reactivity was associated with HCV RNA clearance. Seroreversion was very common following SVR. Upon reinfection, anti-HCV levels increased again. Monitoring anti-HCV levels might therefore be an effective alternative for diagnosis of HCV reinfection. © The Author 2014.

The International Agency for Research on Cancer has declared smoking to be a risk factor for hepatocellular carcinoma (HCC). However, passive exposure to cigarette smoke and use of noncigarette tobacco products on the risk of HCC has not been examined. Therefore, we evaluated the independent effects of different types of smoking exposure along with multiple risk factors for HCC and determined whether the magnitude of smoking was modified by other risk factors in men and women. We conducted a case-control study at The University of Texas M. D. Anderson Cancer Center where 319 HCC patients and 1,061 healthy control subjects were personally interviewed for several HCC risk factors. Multivariate logistic regression analysis was performed to estimate the adjusted odds ratio (AOR) and 95% confidence interval (CI) for each potential risk factor. Use of smokeless tobacco (chewing tobacco and snuff), cigars, pipes and passive smoking exposure were not related to HCC among noncigarette smokers. However, regular cigarette smoking was associated with HCC in men: AOR, 1.9 (95% CI, 1.1–3.1). Heavy alcohol consumption was associated with HCC in women: AOR, 7.7 (95% CI, 2.3–25.1). Cigarette smoking interacted synergistically with chronic infection of hepatitis C virus in men: AOR, 136.3 (95% CI, 43.2–429.6) and with heavy alcohol consumption in women: AOR, 13.7 (95% CI, 3.2–57.9). We conclude that sex differences were observed in HCC relationship with cigarette smoking and alcohol consumption. Controlling for smoking exposure might be a prudent approach to the prevention of HCC, especially in patients with chronic viral hepatitis infections. PMID:18688864

What Factors Are Associated With Receiving a Recommendation to Get Tested for HIV by Health Care Providers Among Men Who Have Sex With Men?

The approach of treatment as prevention for reducing HIV incidence and prevalence hinges on early detection of HIV infection and treatment to achieve viral suppression and, thus, to reduce HIV transmissibility. However, men who have sex with men (MSM), who are at greater risk of HIV infection than the average adult in the United States, are often not tested because many providers do not provide routine opt-out testing or even recommend HIV testing. In a sample of 244 MSM in San Francisco, CA, this study examined whether (1) sociodemographic characteristics (ie, youth, education, employment status, being African American, being Latino), (2) health care access and utilization, and (3) participants disclosing their sexual orientation to their health care providers were associated with their odds of having received a recommendation from a health care provider for HIV testing. Results showed that none of the sociodemographic or health care-related factors were associated with whether a health care provider recommended HIV testing, but MSM disclosing their sexual orientation to their health care providers was associated with an over 8 times greater odds of MSM receiving a recommendation for HIV testing. The study findings underscore the need for routine opt-out HIV testing to screen members of high-risk populations who may not enter the HIV continuum of care and for health care providers to be able to ask patients about HIV risk behavior and sexual orientation and behavior.

In 2007, routine hepatitis C virus (HCV) antibody testing was introduced for men who have sex with men (MSM) with a human immunodeficiency virus (HIV)-positive or unknown status attending a Dutch sexually transmitted infection (STI) outpatient clinic. We evaluated whether this screening resulted in additional and earlier HCV diagnoses among MSM who also attend HIV clinics. At first STI consultation, HIV-positive MSM and MSM opting-out of HIV testing (HIV-status-unknown) were tested for HCV antibodies (anti-HCV). During follow-up consultations, only previously HCV-negative men were tested. Retrospectively, STI clinic and HIV clinic HCV diagnosis dates were compared. One hundred twelve (6.4%) of 1742 (95% confidence interval [CI], 5.3-7.6%) HIV-positive and 3 (0.7%) of 446 (95% CI, 0.2-2.0%) HIV-status-unknown MSM tested anti-HCV-positive at first consultation. During follow-up consultations, 32 HIV-positive (incidence HCV-positive: 2.35/100 person years (PY) (95% CI, 1.66-3.33)) and 0 (1-sided, 97.5% CI, 0.0-3.76) HIV-status-unknown MSM became anti-HCV-positive. Four (11.8%) of 34 HIV-positive MSM notified by their sexual partner of HCV tested anti-HCV-positive.Of 163 HIV-positive MSM with HCV antibodies, 78 reported a history of HCV. HCV diagnosis data at the HIV clinic was requested for the remaining 85 MSM and available for 54 MSM. Of these 54 MSM, 28 (51.9%) had their first HCV diagnosis at the STI clinic, of whom 7 concurrently with HIV. At their next scheduled HIV clinic consultation, 3 HCV cases probably would have been missed. The introduction of routine anti-HCV testing at the STI outpatient clinic resulted in additional and earlier HCV detection among HIV-positive MSM. Testing should be continued among HIV-positive MSM, at least for those not (yet) under the care of an HIV clinic and those notified of HCV by their sexual partner.

During a total population survey of viral hepatitis in the London Boroughs of Hounslow, Richmond and Ealing, 784 patients were seen in three years from 1 March 1972 to 28 February 1975. A diagnosis of viral hepatitis was accepted in 489. The annual incidence was 24 per 100 000. 455 of the patients were tested for the hepatitis B surface antigen (HBsAg) by a radioimmunoassay technique and 93 (20%) of these were positive. The majority of the patients with type B hepatitis were in their third or fourth decades. None was under the age of 16. The male to female ratio among patients with hepatitis B was 2 to 1 in those under the age of 30 and 5 to 1 in those aged 30 and over. The seasonal distribution of viral hepatitis showed a peak in the spring, solely from an increased incidence of non-B hepatitis, and a second, smaller peak in the autumn. There was no appreciable clustering of patients except for one local outbreak in a housing estate during the first year affecting mainly children going to the same primary school, and their parents. Patients with hepatitis B had a longer pre-icteric illness (p less than 0.05), greater duration of jaundice (p less than 0.001) and higher peak levels of serum bilirubin (p less than 0.0005) and serum alanine amino transferase (A1T) (p less than 0.03) than patients with non-B hepatitis. The finding of the surface antigen was also associated with a higher frequency of skin rash (p less than 0.0005) and a greater duration of arthralgia (p less than 0.03). Among the HBsAg negative patients the incidence of arthralgia increased with age (p less than 0.0005). Abdominal pain (p less than 0.005) and vomiting (p less than 0.005) were more common in the young. The injection experience of patients with hepatitis B showed a high proportion of 'non-therapeutic' exposure such as drug addiction. Significantly more HBsAg positive men were single than in the local community (p less than 0.001) or among the HBsAg negative men (p less than 0.01). There

To determine the clinical characteristics of hepatitis B virus (HBV) reactivation in patients undergoing interferon-free antihepatitis C virus (HCV) therapy, we examined HBV DNA in 25 HBV co-infected patients and 765 patients with resolved HBV infection during and after treatment with direct-acting antiviral agents (DAAs). Among those with HCV genotype 1, asunaprevir plus daclatasvir was administered to 160 patients, sofosbuvir (SOF) plus ledipasvir to 438 patients and paritaprevir plus ombitasvir and ritonavir to 25 patients. In total, 167 patients with genotype 2 were treated with SOF plus ribavirin. Three patients with an HBV DNA level ≥2000 IU/mL were treated with entecavir before anti-HCV therapy, without reactivation of HBV. In 3 of 22 (12%) HBV surface antigen (HBsAg)-positive patients with an HBV DNA level <2000 IU/mL, the viral load increased during treatment. However, hepatitis flare did not occur in these patients. There was no significant difference in clinical history between patients with and without HBV reactivation. Among 765 patients with resolved HBV infection, HBV reactivation occurred in 1 (0.1%) patient after initial resolution, whose HBV DNA level spontaneously decreased after DAA therapy. We compared anti-HBs titres at baseline with those at post-DAA therapy in 123 patients without HBsAg. There was no significant difference in anti-HBs levels between the two points (P = .79). In conclusion, HBV reactivation was rare in HBsAg-negative patients treated with DAA therapy. Additionally, hepatitis did not occur in HBV-reactivated patients with a baseline HBV DNA level <2000 IU/mL before DAA therapy. © 2017 John Wiley & Sons Ltd.

To determine if the Advisory Committee on Immunization Practices hepatitis B screening, vaccination, and prophylaxis recommendations were being followed in North Carolina, and to establish a baseline hepatitis B seroprevalence rate. A survey of mother and infant birthing facility medical records. Four birthing facilities selected from each of the 7 districts in North Carolina (a total of 28 facilities). A probability proportional to size survey design was used to select 4763 mother-infant record pairs. All records came from the 1996 birth cohort. Maternal hepatitis B screening status, infant vaccination status, infants prophylaxis status, hepatitis B seroprevalence rate, demographic and clinical predictors for maternal infection, failure to receive prenatal care or for whom status was unknown, failure to screen, and failure to vaccinate. Ninety-two percent of pregnant women were screened for hepatitis B surface antigen. Eighty-six percent of infants received dose 1 of the hepatitis B vaccine. Four of the 9 infants with mothers who were hepatitis B surface antigen-positive did not receive both vaccine and hepatitis B immune globulin. The hepatitis B seroprevalence rate was 0.2%. Mothers who were not screened for infection were 3.4 times more likely to have infants who were not vaccinated. White mothers were twice as likely not to have their child vaccinated as mothers of other races. Not all infants with hepatitis B-infected mothers were receiving vaccine and hepatitis B immune globulin as recommended. Seroprevalence of hepatitis B infection may be lower in North Carolina than in other states. Hepatitis B laboratory test results should be included in every mother's medical record.

The aim of the article is evaluation of the epidemiological situation of hepatitis A in Poland in 2012. Assessment of epidemiological situation of hepatitis A was based on results from analysis of the annual bulletins: "Infectious diseases and poisonings in Poland in 2012", "Vaccinations in Poland in 2012", reports from individual cases and epidemiological investigations of outbreaks linked to hepatitis A, sent by Epidemiological Departments in Sanitary Epidemiological Stations to the Department of Epidemiology at NIPH-NIH. In Poland, 71 cases of hepatitis A were registered in 2012. The incidence of 0.17/ per 100 000 inhabitants was slightly higher than previous year. The incidence of hepatitis A ranged from 0.08/100 000 in Łódzkie and Podlaskie to 0.35/100 000 in Śląskie. The incidence of hepatitis A in men and women was at an approximate level and amounted to 0.19 and 0.18/100 000 respectively. The peak of incidence was recorded during the summer and autumn-winter months. In 2012 imported cases constituted 52.1% of all cases of hepatitis A. There were five outbreaks involving of 11 registered cases in 2012. In 2012, there was a slight increase in the incidence of hepatitis A in compared with the previous year. However, apart from that there were no significant changes in the epidemiological situation of hepatitis A. In Poland there is still very low endemicity for hepatitis A. Decreased incidence and the small number of people vaccinated against hepatitis A facilitates the accumulation of a fairly numerous population of persons susceptible to infection which is connected with the possibility to increase the number of cases of hepatitis A. Despite the fact that the current epidemiological situation of hepatitis A in Poland is good, the disease still requires monitoring and analysis within the framework of epidemiological surveillance system.

Six hepatitis A virus antigenic variants that likely escaped the protective effect of available vaccines were isolated, mostly from men who have sex with men. The need to complete the proper vaccination schedules is critical, particularly in the immunocompromised population, to prevent the emergence of vaccine-escaping variants.

Acute hepatitis A and acute hepatitis B are associated with significant morbidity, time away from work or usual activities, substantial cost to the healthcare system, and some mortality. Despite the availability of vaccines against hepatitis B and hepatitis A since 1981 and 1995, respectively, and a combined hepatitis A and B vaccine since 2001, immunization rates against these vaccine-preventable diseases are appallingly low. In particular, several groups of adults, such as men who have sex with men, heterosexuals with multiple partners, injection drug users, persons with human immunodeficiency virus infection, travelers to endemic areas, and persons with chronic liver disease, are at particularly high risk for acute hepatitis A and B or for a more severe illness or a higher rate of chronicity in the case of hepatitis B. Studies have confirmed that hepatitis A and hepatitis B vaccines are safe and immunogenic in patients in these populations, although patients with more advanced disease may respond less well. These observations have led to the recommendation that patients falling into the above risk groups undergo hepatitis A and B vaccination early in the natural history of their underlying risk behavior or diseases. Vaccination rates are low in clinical practice, and public health and educational programs are needed to overcome barriers to facilitate timely implementation of these recommendations. The use of a combined vaccination, possibly using an accelerated administration schedule, provides convenience and may increase compliance.

Despite the high prevalence of intimate partner violence (IPV) perpetration by men receiving substance use treatment, little is known about their help-seeking behaviors for IPV. A secondary analysis of a mixed-methods study of men receiving substance use treatment who perpetrated IPV examined the prevalence, characteristics, and barriers associated with IPV perpetration disclosure and help-seeking. In total, 170 men were interviewed using a structured questionnaire, and a subsample of 20 were interviewed in-depth about their experiences. Logistic regression determined variables associated with disclosure and help-seeking. Thematic analysis of the in-depth interviews explored barriers to disclosure and help-seeking. Only half the participants had told anyone about their IPV perpetration and about one quarter reported having sought any sort of support. Whereas participants were more likely to disclose their IPV perpetration to informal resources (such as friends or family), they tended to seek help from formal resources (such as health professionals or the police). A greater proportion of physical IPV perpetrators, who had disclosed, had been arrested or had police involvement for IPV, suggesting that their disclosure may not have been voluntary. The following themes emerged from the qualitative data about the barriers to disclosure and help-seeking for IPV perpetration: fear that their children would be taken into care by social services, shame and embarrassment, and a minimization or normalization of their behavior. In addition, many participants highlighted that they had never been previously asked about IPV during treatment for substance use and stressed the need for greater expertise in or knowledge of this topic from specialist services. Substance use treatment services should enquire about men's relationships and IPV perpetration to facilitate disclosure and provide support. Further research is necessary to determine the context of disclosure and help

The health of Australian men has recently received greater attention. Men's Sheds are named in national policy as an exemplar community-based organisation for the betterment of men's psychosocial health; yet, the evidence base to support this is limited. This study investigates the comparative experience of men with long-term disabilities and men without long-term disabilities who go to a Men's Shed and to what extent this provides these men with an enabling, as opposed to disabling, environment. Data were collected from 12 individual interviews with men with long-term disabilities (5) and men without long-term disabilities (6), including 1 interview with the male Men's Shed Coordinator (MSC); participant observation within the shed; and a document received from the female MSC regarding the funding the Shed receives. Interviews explored the men's experiences at the Shed and their sense of belonging and social inclusion. Participants had any type of long-term disability and had been attending the shed for a minimum of 1 month. Data were collected between May and September 2013 and were analysed using the constant comparative method of grounded theory. The core theme that emerged was an enabling community space. The four sub-themes were: a community and social hub; an equalising space; a safe and supportive male environment; and meaningful male activities. The current literature exemplifies Men's Sheds to be important community-based organisations beneficial to men's health and well-being. For men living with long-term disabilities, this study illuminates that Men's Sheds offer an environment of equality, facilitating a collegial and egalitarian culture. Men can partake in enabling activities and enjoy the company of other men enhancing their sense of belonging and social inclusion as well as interact with other community groups that occupy the same space as the Men's Shed. © 2014 John Wiley & Sons Ltd.

Natural history of hepatitis C.

Westbrook, Rachel H; Dusheiko, Geoffrey

There has long been evidence that hepatitis C can lead to persistent infection in a high proportion of infected individuals, and can progress to chronic liver disease, cirrhosis and hepatocellular carcinoma (HCC). The transition from acute to chronic hepatitis C is usually sub-clinical. Accurate studies of the time course for clearance of acute hepatitis C are difficult to carry out because of the silent onset of the acute disease. The likelihood of spontaneous HCV resolution is associated with several genetic factors, including IL28B inheritance and the DQB1*0301 allele of the major histocompatibility complex class II. Most data suggest that resolution in the acute phase without progression to chronic disease is not accompanied by significant disease, but minor histological lesions have been observed in anti-HCV positive, HCV RNA negative individuals. The risk of reinfection remains a possibility after clearance of acute hepatitis C. High rates of sexually-transmitted infection are being reported in HIV positive men who have sex with men (MSM). Chronic infection with HCV is the leading cause of end-stage liver disease, hepatocellular carcinoma (HCC) and liver related death in the Western world. The natural history of the chronic disease remains incompletely defined. It is generally a slowly progressive disease characterized by persistent hepatic inflammation, leading to the development of cirrhosis in approximately 10-20% of patients over 20-30 years of HCV infection. However, the published data indicate varying progression rates to cirrhosis. Overall, once cirrhosis has developed there is a 1-5% annual risk of HCC and a 3-6% annual risk of hepatic decompensation. Following an episode of decompensation the risk of death in the following year is between 15% and 20%. The high number of chronically infected individuals, the burden of disease, and the absence of a vaccine indicates that treatment will form part of the disease control but the impact, effectiveness and

Prolactin (PRL) is a multifunctional polypeptide with effects on metabolism, however, little is known about its effect on hepatic steatosis and lipid metabolism. Herein, we aimed to assess the role of PRL in the development of non-alcoholic fatty liver disease (NAFLD). The serum PRL levels of 456 patients with NAFLD, 403 controls without NAFLD diagnosed by ultrasound, and 85 individuals with liver histology obtained during metabolic surgery (44 female and 30 male patients with NAFLD and 11 age-matched non-NAFLD female individuals) were evaluated. The expression of the gene encoding the prolactin receptor (PRLR) and signalling molecules involved in hepatic lipid metabolism were evaluated in human liver and HepG2 cells. The effects of overexpression of PRLR or fatty acid translocase (FAT)/CD36 or knockdown of PRLR on hepatic lipid metabolism were tested in free fatty acid (FFA)-treated HepG2 cells. Circulating PRL levels were lower in individuals with ultrasound-diagnosed NAFLD (men: 7.9 [range, 5.9-10.3] µg/L; women: 8.7 [range, 6.1-12.4] µg/L) than those with non-NAFLD (men: 9.1 [range, 6.8-13.0] µg/L, p = 0.002; women: 11.6 [range, 8.2-16.1] µg/L, p <0.001). PRL levels in patients with biopsy-proven severe hepatic steatosis were lower compared with those with mild-to-moderate hepatic steatosis in both men (8.3 [range, 5.4-9.5] µg/L vs. 9.7 [range, 7.1-12.3] µg/L, p = 0.031) and women (8.5 [range, 4.2-10.6] µg/L vs. 9.8 [range, 8.2-15.7] µg/L, p = 0.027). Furthermore, hepatic PRLR gene expression was significantly reduced in patients with NAFLD and negatively correlated with CD36 gene expression. In FFA-induced HepG2 cells, PRL treatment or PRLR overexpression significantly reduced the expression of CD36 and lipid content, effects that were abrogated after silencing of PRLR. Furthermore, overexpression of CD36 significantly reduced the PRL-mediated improvement in lipid content. Our results reveal a novel association between the

Hepatic steatosis occurs in 40-70% of patients chronically infected with hepatitis C virus [chronic hepatitis C (CH-C)]. Hepatic steatosis in CH-C is associated with progressive liver disease and a low response rate to antiviral therapy. Gene expression profiles were examined in CH-C patients with and without hepatic steatosis, non-alcoholic steatohepatitis (NASH) and fibrosis. This study included 65 CH-C patients who were not receiving antiviral treatment. Total RNA was extracted from peripheral blood mononuclear cells, quantified and used for one-step reverse transcriptase-polymerase chain reaction to profile 153 mRNAs that were normalized with six 'housekeeping' genes and a reference RNA. Multiple regression and stepwise selection assessed differences in gene expression and the models' performances were evaluated. Models predicting the grade of hepatic steatosis in patients with CH-C genotype 3 involved two genes: SOCS1 and IFITM1, which progressively changed their expression level with the increasing grade of steatosis. On the other hand, models predicting hepatic steatosis in non-genotype 3 patients highlighted MIP-1 cytokine encoding genes: CCL3 and CCL4 as well as IFNAR and PRKRIR. Expression levels of PRKRIR and SMAD3 differentiated patients with and without superimposed NASH only in the non-genotype 3 cohort (area under the receiver operating characteristic curve=0.822, P-value 0.006]. Gene expression signatures related to hepatic fibrosis were not genotype specific. Gene expression might predict moderate to severe hepatic steatosis, NASH and fibrosis in patients with CH-C, providing potential insights into the pathogenesis of hepatic steatosis and fibrosis in these patients.

The objective of this study was to analyse associations between sexualised substance use (chemsex), STI diagnoses and sexual behaviour among gay bisexual and other men who have sex with men accessing sexual health clinics to better inform clinical pathways. A retrospective case notes review was undertaken following the introduction of more detailed and holistic profomas for all gay bisexual and other men who have sex with men attending two London sexual health clinics between 1 June 2014 and 31 January 2015. Chemsex status was documented for 655/818. Overall, 30% disclosed recreational drug use of whom 113 (57%) disclosed chemsex and 27 (13.5%) injecting drugs. HIV-positive gay bisexual and other men who have sex with men were more likely to disclose chemsex (AOR 6.68; 95% CI 3.91-11.42; p < 0.001). Those disclosing chemsex had a higher incidence of acute bacterial STIs (AOR 2.83 CI 1.79-4.47; p < 0.001), rectal STIs (AOR 3.10 CI 1.81-5.32; p < 0.001) or hepatitis C (AOR 15.41 CI 1.50-158.17; p = 0.021). HIV incidence in the study period was 1.8% (chemsex) vs. 0.9% (no chemsex) (p = 0.61). Chemsex was associated with having more sexual partners, transactional sex, group sex, fisting, sharing sex toys, injecting drug use, higher alcohol consumption and the use of 'bareback' sexual networking applications (p < 0.004). Chemsex participants were also more likely to have accessed post-exposure prophylaxis for HIV in the study period and report sex with a discordant HIV or hepatitis C-infected partner (p < 0.001). Chemsex disclosure is associated with higher risk-taking behaviours, acute bacterial STIs, rectal STIs and hepatitis C incidence. HIV incidence was higher but not significantly so in the study period. Chemsex disclosure in sexual health clinics should prompt an opportunity for prevention, health promotion and wellbeing interventions.

Taira, Al V.; Merrick, Gregory S., E-mail: gmerrick@urologicresearchinstitute.org; Galbreath, Robert W.

Purpose: To assess whether small prostate size is an adverse prognostic factor in men undergoing brachytherapy in the same manner in which it seems to be for men undergoing radical prostatectomy. Methods and Materials: From April 1995 to June 2008, 2024 patients underwent brachytherapy by a single brachytherapist. Median follow-up was 7.4 years. The role of small prostate size ({<=}20 cm{sup 3}) as a prognostic factor for biochemical progression-free survival, cause-specific survival, and all-cause mortality was investigated. The differences in survival between men with small and larger prostates were compared using Kaplan-Meier curves and log-rank tests. Results: Median prostate sizemore » for the entire cohort was 32.7 cm{sup 3}. For the 167 men with small prostates, median prostate size was 17.4 cm{sup 3}. There was no difference in biochemical progression-free survival (95.2% vs 96.2%, P=.603), cause-specific survival (97.7% vs 98.3%, P=.546), or all-cause mortality (78.0% vs 77.2%, P=.838) at 10 years for men with small prostates compared with men with larger prostates. On univariate and multivariate analysis, small prostate size was not associated with any of the primary outcome measures. Conclusion: Men with small prostates treated with brachytherapy have excellent outcomes and are at no higher risk of treatment failure than men with larger glands. High-quality implants with adequate margins seem sufficient to address the increased adverse risk factors associated with small prostate size.« less

Most professional organizations, including the American College of Physicians and U.S. Preventive Services Task Force, emphasize that screening for prostate cancer with the prostate-specific antigen (PSA) test should only occur after a detailed discussion between the health-care provider and patient about the known risks and potential benefits of the test. In fact, guidelines strongly advise health-care providers to involve patients, particularly those at elevated risk of prostate cancer, in a "shared decision making" (SDM) process about PSA testing. We analyzed data from the National Cancer Institute's Health Information National Trends Survey 2011-2012-a nationally representative, cross-sectional survey-to examine the extent to which health professionals provided men with information critical to SDM prior to PSA testing, including (1) that patients had a choice about whether or not to undergo PSA testing, (2) that not all doctors recommend PSA testing, and (3) that no one is sure if PSA testing saves lives. Over half (55 %) of men between the ages of 50 and 74 reported ever having had a PSA test. However, only 10 % of men, regardless of screening status, reported receiving all three pieces of information: 55 % reported being informed that they could choose whether or not to undergo testing, 22 % reported being informed that some doctors recommend PSA testing and others do not, and 14 % reported being informed that no one is sure if PSA testing actually saves lives. Black men and men with lower levels of education were less likely to be provided this information. There is a need to improve patient-provider communication about the uncertainties associated with the PSA test. Interventions directed at patients, providers, and practice settings should be considered.

Hepatitis B core antibody immunoglobulin G seropositivity is evidence of past exposure to hepatitis B virus. Donor or recipient hepatitis B core antibody positivity may pose a risk of reactivation, especially early after liver transplant. Although most centers advocate using antiviral agents plus hepatitis B immunoglobulin, some have recently relied on antivirals only as prophylaxis after liver transplant. Here, we retrospectively investigated patient survival in hepatitis B core antibody-positive recipients, comparing those treated with antivirals plus hepatitis B immunoglobulin versus antivirals alone. After Internal Review Board approval, we reviewed medical records of deceased-donor liver transplant recipients between 1995 and 2013. Demographic characteristics, transplant indication, hepatitis B core antibody status, time to death, and type of posttransplant prophylaxis were recorded. We also recorded whether donors showed hepatitis B core antibody positivity. Patients who died within 30 days of liver transplant were excluded. There were 148 hepatitis B core antibody-positive recipients. Prophylaxis was given to 75 recipients after transplant: 8 (5%) received hepatitis B immunoglobulin, 22 (15%) received antivirals, and 45 (30%) received the combination. There were 34 deaths: 3 (38%) in hepatitis B immunoglobulin only, 3 (14%) in antiviral only, 8 (18%) in the combination, and 20 (27%) in no prophylaxis groups. One- and 5-year survival rates were similar for binary comparisons among prophylaxis groups (P > .05). Preliminary results support the current practice of using hepatitis B immunoglobulin plus antivirals for prophylaxis after liver transplant. The similar survival benefit with the combination versus antiviral agents alone suggests equal effectivity for prophylaxis posttransplant. However, a clear benefit of antivirals was not evident in our analysis. Future larger prospective studies are warranted to identify potential benefits of using antivirals alone

We summarize the clinical history and laboratory results following the introduction of tenofovir among 6 patients coinfected with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) who presented with severe liver disease while receiving lamivudine-based highly active antiretroviral therapy. In all cases, the introduction of tenofovir led to a sustained undetectable HBV and HIV loads, with marked clinical and laboratory improvement in liver function. We provide supporting evidence for the role of tenofovir in the management of advanced HBV infection in HIV-positive patients after the development of lamivudine resistance.

Hepatitis A is related to significant morbidity and occasional mortality. Based on data from the Polish National Institute of Hygiene, from 2000 to 2013 a mean of 213 hepatitis A cases were reported yearly. The aim of the study was to assess selected data in adults hospitalized for symptomatic hepatitis A during an eight-year period in a single center in the Wielkopolska Region of Poland. All the hepatitis A patients hospitalized in the center from 2005 to 2013 were analyzed retrospectively. Data were extracted from the medical records of these individuals. The disease was confirmed by anti-HAV IgM testing. In total, 108 patients (71 men and 37 women), aged 18-65 years, were identified. All but 1 patient recovered (99.1%) and in 6 cases (5.6%) a relapse occurred. Risk factors for hepatitis A were identified in 56 patients (52%), with travel abroad being the most common one (32 patients); 19 cases were secondary and 5 patients were men who have sex with men. One hepatitis A outbreak was noted in the region during the study period. Acalculous cholecystitis was found in 33.3% of the patients who underwent abdominal ultrasound. This tended to be more common among older individuals (47.8% in patients over 40 vs. 22.6% in patients aged 18-40, p=0.0521). Patients with this finding had significantly higher mean peak ALT in comparison to those with no gallbladder abnormalities. Although hepatitis A in adults is typically a benign, self-limited disease, it can occasionally have a fatal course. In a significant proportion of patients with an evident risk factor for hepatitis A, the possibility of active prophylaxis was not used. Hepatitis A should be regarded as a sexually transmitted infection. Acalculous cholecystitis is a frequent finding among adults with symptomatic hepatitis A.

Missed Opportunities for Hepatitis A Vaccination, National Immunization Survey-Child, 2013.

To quantify the number of missed opportunities for vaccination with hepatitis A vaccine in children and assess the association of missed opportunities for hepatitis A vaccination with covariates of interest. Weighted data from the 2013 National Immunization Survey of US children aged 19-35 months were used. Analysis was restricted to children with provider-verified vaccination history (n = 13 460). Missed opportunities for vaccination were quantified by determining the number of medical visits a child made when another vaccine was administered during eligibility for hepatitis A vaccine, but hepatitis A vaccine was not administered. Cross-sectional bivariate and multivariate polytomous logistic regression were used to assess the association of missed opportunities for vaccination with child and maternal demographic, socioeconomic, and geographic covariates. In 2013, 85% of children in our study population had initiated the hepatitis A vaccine series, and 60% received 2 or more doses. Children who received zero doses of hepatitis A vaccine had an average of 1.77 missed opportunities for vaccination compared with 0.43 missed opportunities for vaccination in those receiving 2 doses. Children with 2 or more missed opportunities for vaccination initiated the vaccine series 6 months later than children without missed opportunities. In the fully adjusted multivariate model, children who were younger, had ever received WIC benefits, or lived in a state with childcare entry mandates were at a reduced odds for 2 or more missed opportunities for vaccination; children living in the Northeast census region were at an increased odds. Missed opportunities for vaccination likely contribute to the poor coverage for hepatitis A vaccination in children; it is important to understand why children are not receiving the vaccine when eligible.

The objective of this study was to examine Hepatitis A (HAV) and Hepatitis B (HBV) screening, and the risk of HBV reactivation during Hepatitis C (HCV) therapy with direct-acting antivirals (DAAs). A retrospective chart review was performed of patients treated with second generation DAA therapy from January 2014 to September 2016 at the Iowa City VA Healthcare System. In total 409 patients initiated HCV treatment, 308 (75%) and 241 (59%) were HAV and HBV vaccine eligible, respectively. Among those, 24 (8%) received a HAV vaccine, while only 20 (8%) received a HBV vaccine. Of these, 7 patients initiating an immunization in the clinic had record of completing the series. Further, 101 patients had a reactive Hepatitis B core Antibody indicating previous HBV infection, and 3 of these were tested for HBV reactivation during HCV therapy. Overall, the assessment found low rates of HAV and HBV vaccine administration, indicating missed opportunities for preventative care during HCV therapy. With the known risk of HBV reactivation with DAAs, the need for HAV and HBV screening is essential.

Direct-acting antivirals (DAAa) cure hepatitis C virus (HCV) infections in 95% of infected patients. Modeling studies predict that universal HCV treatment will lead to a decrease in the incidence of new infections but real-life data are lacking. The incidence of HCV among Dutch human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) has been high for >10 years. In 2015 DAAs became available to all Dutch HCV patients and resulted in a rapid treatment uptake in HIV-positive MSM. We assessed whether this uptake was followed by a decrease in the incidence of HCV infections. Two prospective studies of treatment for acute HCV infection enrolled patients in 17 Dutch HIV centers, having 76% of the total HIV-positive MSM population in care in the Netherlands. Patients were recruited in 2014 and 2016, the years before and after unrestricted DAA availability. We compared the HCV incidence in both years. The incidence of acute HCV infection decreased from 93 infections during 8290 person-years of follow-up (PYFU) in 2014 (11.2/1000 PYFU; 95% confidence interval [CI], 9.1-13.7) to 49 during 8961 PYFU in 2016 (5.5/1000 PYFU; 4.1-7.2). The incidence rate ratio of 2016 compared with 2014 was 0.49 (95% CI, .35-.69). Simultaneously, a significant increase in the percentage positive syphilis (+2.2%) and gonorrhea (+2.8%) tests in HIV-positive MSM was observed at sexual health clinics across the Netherlands and contradicts a decrease in risk behavior as an alternative explanation. Unrestricted DAA availability in the Netherlands was followed by a 51% decrease in acute HCV infections among HIV-positive MSM.

The Hepatitis Testing and Linkage to Care (HepTLC) initiative promoted viral hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites from 2012 to 2014. Through the HepTLC initiative, the Minnesota Department of Health (MDH) and clinic partners began conducting linkage-to-care activities with hepatitis B-positive refugees in October 2012. This intervention provided culturally appropriate support to link refugees to follow-up care for hepatitis B. MDH refugee health and viral hepatitis surveillance programs, along with clinics that screened newly arrived refugees in Hennepin and Ramsey counties in Minnesota, collaborated on the project, which took place from October 1, 2012, through September 30, 2014. Bilingual care navigators contacted refugees to provide education, make appointments, and arrange transportation. We compared the linkage-to-care rate for participants with the rates for refugees screened the year before project launch using a two-sample test of proportions. In the year preceding the project (October 2011 through September 2012), 87 newly arrived refugees had a positive hepatitis B surface antigen (HBsAg) test. Fifty-six (64%) refugees received follow-up care, 12 (14%) refugees did not receive follow-up care, and 19 (22%) refugees could not be located and had no record of follow-up care. During the project, 174 HBsAg-positive, newly arrived refugees were screened. Of those 174 refugees, 162 (93%) received follow-up care, seven (4%) did not receive follow-up care, and five (3%) could not be located and had no record of follow-up care. The one-year linkage-to-care rate for project participants (93%) was significantly higher than the rate for refugees screened the previous year (64%) (p<0.001). In the context of a strong screening and surveillance infrastructure, a simple intervention improved the linkage-to-care rate for HBsAg-positive refugees.

Burn injury causes hepatic dysfunction associated with endoplasmic reticulum (ER) stress and induction of the unfolded protein response (UPR). ER stress/UPR leads to hepatic apoptosis and activation of the Jun-N-terminal kinase (JNK) signaling pathway, leading to vast metabolic alterations. Insulin has been shown to attenuate hepatic damage and to improve liver function. We therefore hypothesized that insulin administration exerts its effects by attenuating postburn hepatic ER stress and subsequent apoptosis. Male Sprague Dawley rats received a 60% total body surface area (TBSA) burn injury. Animals were randomized to receive saline (controls) or insulin (2.5 IU/kg q. 24 h) and euthanized at 24 and 48 h postburn. Burn injury induced dramatic changes in liver structure and function, including induction of the ER stress response, mitochondrial dysfunction, hepatocyte apoptosis, and up-regulation of inflammatory mediators. Insulin decreased hepatocyte caspase-3 activation and apoptosis significantly at 24 and 48 h postburn. Furthermore, insulin administration decreased ER stress significantly and reversed structural and functional changes in hepatocyte mitochondria. Finally, insulin attenuated the expression of inflammatory mediators IL-6, MCP-1, and CINC-1. Insulin alleviates burn-induced ER stress, hepatocyte apoptosis, mitochondrial abnormalities, and inflammation leading to improved hepatic structure and function significantly. These results support the use of insulin therapy after traumatic injury to improve patient outcomes.

ER stress/UPR leads to hepatic apoptosis and activation of the Jun-N-terminal kinase (JNK) signaling pathway, leading to vast metabolic alterations. Insulin has been shown to attenuate hepatic damage and to improve liver function. We therefore hypothesized that insulin administration exerts its effects by attenuating postburn hepatic ER stress and subsequent apoptosis. Male Sprague Dawley rats received a 60% total body surface area (TBSA) burn injury. Animals were randomized to receive saline (controls) or insulin (2.5 IU/kg q. 24 h) and euthanized at 24 and 48 h postburn. Burn injury induced dramatic changes in liver structure and function, including induction of the ER stress response, mitochondrial dysfunction, hepatocyte apoptosis, and up-regulation of inflammatory mediators. Insulin decreased hepatocyte caspase-3 activation and apoptosis significantly at 24 and 48 h postburn. Furthermore, insulin administration decreased ER stress significantly and reversed structural and functional changes in hepatocyte mitochondria. Finally, insulin attenuated the expression of inflammatory mediators IL-6, MCP-1, and CINC-1. Insulin alleviates burn-induced ER stress, hepatocyte apoptosis, mitochondrial abnormalities, and inflammation leading to improved hepatic structure and function significantly. These results support the use of insulin therapy after traumatic injury to improve patient outcomes. PMID:21267509

On-treatment response of serum hepatitis C virus (HCV) is reportedly less useful to predict the outcome of anti-HCV therapy with interferon (IFN)-free regimen with direct-acting antivirals than with IFN-based regimens in clinical trials. We evaluated the significance of very early viral response after the start of therapy, which indicates direct HCV response to the drugs, on therapeutic outcome. Reductions in serum HCV-RNA levels were measured at 1 day after the start of therapy in 544 patients who underwent IFN-free direct-acting antiviral regimens. The association between these reductions and the achievement or failure of sustained virologic response (SVR) was evaluated. Patient characteristics did not influence 1-day reduction in serum HCV-RNA except for liver fibrosis. There was no difference in 1-day HCV reduction between SVR and non-SVR patients treated with a 24-week regimen. In contrast, in patients treated with a 12-week regimen, 1-day reduction was significantly greater in SVR than in non-SVR patients (P = 0.0013) and was predictive of SVR versus non-SVR (area under the receiver-operating characteristics curve: 0.80). Whereas the reduction in serum HCV-RNA levels at 1 day after the start of therapy was not associated with treatment outcomes in patients who underwent a 24-week regimen of IFN-free therapy, there was an association in patients receiving a 12-week regimen, and this reduction was predictive of SVR, thus potentially serving as a factor to identify patients at risk of treatment failure. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

We report a 61-year-old woman who was hospitalized because of abdominal pain in the right upper quadrant related to a liver tumor (ultrasound and tomographic findings). A collection of blood was obtained by a biopsy and there were no tumor cells. With the suspicion of acute fascioliasis (liver stage), due to severe eosinophilia and recent travel to endemic area of Fasciola hepatica, arc II and ELISA Fas 2 we carried out and were positive. Parasitological stool examinations were negative. During hospitalization a hepatic subcapsular hematoma presented as a complication and the patient developed fever because of cholangiolitic microabscesses in the left hepatic lobe. Percutaneous drainage was performed and positive cultures of secretions were obtained She received antibiotic coverage with vancomycin and imipenem. Treatment for Fasciola hepatica was initiated with nitaxozanida but it was discontinued due to oral intolerance. Later, she received a single dose of 250 mg triclabendazole with clinical and laboratory improvement. We presented this case because it is an unusual pseudotumoral presentation in acute hepatic fascioliasis. This parasitic disease is an emerging zoonosis in Perú.

Fasting promotes triglyceride (TG) accumulation in lean tissues of some animals, but the effect in humans is unknown. Additionally, fasting lipolysis is sexually dimorphic in humans, suggesting that lean tissue TG accumulation and metabolism may differ between women and men. This study investigated lean tissue TG content and metabolism in women and men during extended fasting. Liver and muscle TG content were measured by magnetic resonance spectroscopy during a 48-h fast in healthy men and women. Whole-body and hepatic carbohydrate, lipid, and energy metabolism were also evaluated using biochemical, calorimetric, and stable isotope tracer techniques. As expected, postabsorptive plasma fatty acids (FAs) were higher in women than in men but increased more rapidly in men with the onset of early starvation. Concurrently, sexual dimorphism was apparent in lean tissue TG accumulation during the fast, occurring in livers of men but in muscles of women. Despite differences in lean tissue TG distribution, men and women had identical fasting responses in whole-body and hepatic glucose and oxidative metabolism. In conclusion, TG accumulated in livers of men but in muscles of women during extended fasting. This sexual dimorphism was related to differential fasting plasma FA concentrations but not to whole body or hepatic utilization of this substrate. PMID:22140269

Hepatitis B virus (HBV) and hepatitis C virus (HCV), discovered as causative viruses of post-transfusion hepatitis, become persistent infections, leading to chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). For HCV, recent IFN-free direct-acting antiviral (DAA) therapies have increased sustained virological response (SVR) rates and reduced adverse events. IFN-based therapies, still the standard of care in Asian countries, are influenced by IL28B genetic variants and the liver fibrosis stage, but the DAA combinations obscure the influence of these factors. These new therapies can eradicate HCV and prevent HCC development. On the other hand, it is difficult to eradicate HBV completely. Although HBV infection can be prevented by vaccination, reactivation of HBV following anti-cancer chemotherapy and immunosuppressive therapy is a well-known complication. HBV reactivation has been reported to be associated with anti-CD20 monoclonal antibody rituximab-containing chemotherapy and TNF-α inhibitor-containing immunosuppressive therapy in HBV-resolved patients. Our prospective observational study revealed that monthly monitoring of HBV DNA was useful for preventing HBV reactivation-related hepatitis among B-cell non-Hodgkin lymphoma patients with resolved HBV infection following rituximab-steroid-chemo, suggesting that preemptive therapy guided by serial HBV DNA monitoring should be recommended. Recently, highly sensitive HBsAg detection by Lumipulse HBsAg-HQ may be useful for several clinical applications. The sensitivity of this assay (5 mIU/mL) was approximately 10-fold higher than Abbott ARCHITECT, but still lower than HBV-DNA assays. The convenient HBsAg-HQ may be useful for detecting occult HBV infection and HBV reactivation in relatively low-risk groups except for those receiving rituximab-steroid-chemo. [

The proportion of newly diagnosed HIV and STI cases among men who have sex with men (MSM) that were contracted abroad has been increasing in Sweden. The present study explored factors associated with casual unprotected anal intercourse (UAI) and travelling abroad among MSM. A cross-sectional stratified survey with 2751 MSM was conducted. The frequency of sexual practices among men who had casual UAI abroad (<12 months) with that of men who had casual UAI only in Sweden were compared and factors associated with casual UAI abroad were identified through regression analysis. Factors associated with casual UAI abroad within the previous 12 months were: visit a gay sauna (OR 6.15, 95% CI 3.43-11.06), visit gay café/bar/pub (OR 3.24, 95% CI 1.62-6.48), experience of UAI with a foreign visitor (OR 4.80, 95% CI 2.37-9.75), living with HIV (OR 2.73, 95% CI 1.15-6.48), reporting poor overall health (OR 2.24, 95% CI 1.13-4.44), being born outside Sweden (OR 2.21, 95% CI 1.08-4.53), and being vaccinated against hepatitis A, hepatitis B, or both (OR 1.92, 95% CI 1.13-3.27). MSM who engage in casual UAI abroad need to increase their understanding of related risks and that risk varies with place and practice. Health care professionals should address the preventive needs of traveling MSM and offer counselling and STI-preventive measures. Copyright © 2018 Elsevier Ltd. All rights reserved.

Prostate cancer patients who receive androgen deprivation therapy (ADT) often experience many physical and psychological side effects. ADT may be associated with increased risk for depression, but the relationship between ADT and depression is not fully understood. This study used a longitudinal design to assess depressive symptomatology in patients receiving ADT compared with two groups of matched controls. Participants were men initiating ADT treatment (ADT+ group; n = 61) and their matched controls: prostate cancer patients treated with radical prostatectomy (ADT- group; n = 61), and no-cancer controls (CA- group; n = 61). Depressive symptomatology was assessed using the Center for Epidemiological Studies Depression Scale at ADT initiation and again 6 months later. Differences in depressive symptomatology and rates of clinically significant depressive symptomatology were analyzed between groups at each time point and within groups over time. Between baseline and follow-up, ADT+ participants demonstrated increased depressive symptomatology and increased rates of clinically significant depressive symptomatology (ps < 0.05). ADT+ participants also reported greater depressive symptomatology than both control groups at follow-up (ps < 0.001). Rates of clinically significant depressive symptomatology were higher in the ADT+ group than the ADT- and CA- groups at both time points (baseline: 28%, 5%, 12%; follow-up: 39%, 9%, 11%). Findings support the hypothesis that ADT administration yields increases in depression and suggest that the mechanism behind ADT's association with depression should be explored and that prostate cancer patients treated with ADT should receive particular focus in depression screening and intervention.

Objective Prostate cancer patients who receive androgen deprivation therapy (ADT) often experience many physical and psychological side effects. ADT may be associated with increased risk for depression, but the relationship between ADT and depression is not fully understood. This study used a longitudinal design to assess depressive symptomatology in patients receiving ADT compared to two groups of matched controls. Methods Participants were men initiating ADT treatment (ADT+ group; n = 61) and their matched controls: prostate cancer patients treated with radical prostatectomy (ADT− group; n = 61) and no-cancer controls (CA− group; n = 61). Depressive symptomatology was assessed using the Center for Epidemiological Studies Depression Scale at ADT initiation and again six months later. Differences in depressive symptomatology and rates of clinically-significant depressive symptomatology were analyzed between groups at each time point and within groups over time. Results: Between baseline and follow-up, ADT+ participants demonstrated increased depressive symptomatology and increased rates of clinically-significant depressive symptomatology (ps < .05). ADT+ participants also reported greater depressive symptomatology than both control groups at follow-up (ps < .001). Rates of clinically-significant depressive symptomatology were higher in the ADT+ group than the ADT− and CA− groups at both time points (baseline: 28%, 5%, 12%; follow-up: 39%, 9%, 11%). Conclusions Findings support the hypothesis that ADT administration yields increases in depression and suggest that the mechanism behind ADT’s association with depression should be explored and that prostate cancer patients treated with ADT should receive particular focus in depression screening and intervention.

Hepatitis C virus (HCV) has become a significant source of morbidity and mortality in HIV-infected patients. However, little is known about the clinical presentation and course of acute HCV infection in this population. This study reports the outcomes of acute HCV infection in 9 HIV-infected men. Sex with men was the only reported risk factor for HCV infection in 6 of the subjects. Clinical presentation of acute HCV ranged from incidentally discovered elevated transaminases to severe liver dysfunction requiring hospitalization. At the time of HCV diagnosis, 8 of 9 patients had CD4+ counts >250 cells/mm(3), and 6 had HIV viral loads of < or =5000 copies/mL. Eight patients were receiving antiretroviral therapy. Outcome of these acute HCV infections varied. Five patients experienced virologic clearance, 2 in whom virus cleared spontaneously and 3 who were treated with pegylated interferon and ribavirin. Four patients developed chronic infection, one of whom had a relapse during HCV treatment and 3 of whom were untreated. All 4 patients to whom HCV therapy was administered experienced significant anemia or neutropenia, necessitating dose reduction or support with growth factors. Prompt recognition of acute HCV infection may minimize antiretroviral treatment interruption and will allow early treatment, which may improve virologic clearance. Unexplained transaminase elevations in HIV-infected patients, including men who have sex with men, should trigger an evaluation for acute HCV infection.

The aim of this study was to compare hepatic standardized uptake values (SUVs) and hepatic metabolic volumetric products (HMVP) between patients of diffuse hepatic steatosis and control subjects with normal livers. Twenty-seven subjects were included in the study (13 men and 14 women; age range, 34-72 years). All had 18F-2-fluoro-2-D-deoxyglucose-positron emission tomography (FDG-PET) and magnetic resonance imaging (MRI) scans with an interscan interval of 0-5 months. Twelve of 27 subjects had diffuse hepatic steatosis on MRI. The remaining 15 were selected as age-matched controls based on normal liver parenchyma on MRI. Mean and maximum hepatic SUVs were calculated for both patient groups on FDG-PET images. Hepatic volumes were measured from MRI. HMVP in each subject was subsequently calculated by multiplication of hepatic volume by mean hepatic SUV. HMVPs as well as mean and maximum hepatic SUVs were compared between the two study groups. HMVPs, mean hepatic SUVs, and maximum hepatic SUVs were greater (statistically significant, p < 0.05) in subjects with diffuse hepatic steatosis compared to those in the control group. The increase in HMVP is the result of increased hepatic metabolic activity likely related to the diffuse hepatic steatosis. The active inflammatory process related to the diffuse hepatic steatosis is the probable explanation for the increase in hepatic metabolic activity on FDG-PET study.

Newborns who have received hepatitis B immunization in 1980s are now young adults joining healthcare disciplines. The need for booster, pre- and post-booster checks becomes a practical question. The aim of this study is to refine the HBV vaccination policy for newly admitted students in the future. A prospective study on medical and nursing school entrants to evaluate hepatitis B serostatus and the response to booster doses among young adults. Among 212 students, 17-23-year-old, born after adoption of neonatal immunization, 2 (0.9%) were HBsAg positive, 40 (18.9%) were anti-HBs positive. At 1 month after a single-dose booster for anti-HBs-negative students, 14.5% had anti-HBs <10 mIU/mL, 29.0% and 56.5% were 10-100 and >100 mIU/mL, respectively. The anti-HBs levels were significantly higher for females than males (mean [SD]: 431 [418] vs. 246 [339] mIU/mL, P = 0.047). At 2-4 month after the third booster dose, 97.1% had anti-HBs >100 mIU/mL and 2.9% had 10-100 mIU/mL. Pre-booster check is still worthwhile to identify carriers among newly recruited healthcare workers born after adoption of neonatal immunization. A 3-dose booster, rather than a single dose, is required for the majority to achieve an anti-HBs level >100 mIU/mL, as memory immunity has declined in a substantial proportion of individuals. Cost-effectiveness of post-booster check for anti-HBs is low and should be further evaluated based on contextual specific utilization of results.

To investigate whether fecal microbiota transplantation (FMT) prevents hepatic encephalopathy (HE) in rats with carbon tetrachloride (CCl 4 )-induced acute hepatic dysfunction. A rat model of HE was established with CCl 4 . Rat behaviors and spatial learning capability were observed, and hepatic necrosis, intestinal mucosal barrier, serum ammonia levels and intestinal permeability were determined in HE rats receiving FMT treatment. Furthermore, the expression of tight junction proteins (Claudin-1, Claudin-6 and Occludin), Toll-like receptor (TLR) 4/TLR9, interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α was examined. FMT improved rat behaviors, HE grade and spatial learning capability. Moreover, FMT prevented hepatic necrosis and intestinal mucosal barrier damage, leading to hepatic clearance of serum ammonia levels and reduced intestinal permeability. The expression of TLR4 and TLR9, two potent mediators of inflammatory response, was significantly downregulated in the liver of rats treated with FMT. Consistently, circulating pro-inflammatory factors such as interleukin (IL)-1β, IL-6 and tumor necrosis factor-α were remarkably decreased, indicating that FMT is able to limit systemic inflammation by decreasing the expression of TLR4 and TLR9. Importantly, HE-induced loss of tight junction proteins (Claudin-1, Claudin-6 and Occludin) was restored in intestinal tissues of rats receiving FMT treatment. FMT enables protective effects in HE rats, and it improves the cognitive function and reduces the liver function indexes. FMT may cure HE by altering the intestinal permeability and improving the TLR response of the liver.

Non alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease and ongoing research efforts are focused on understanding the underlying pathophysiology of hepatic steatosis with the anticipation that these efforts will identify novel therapeutic targets. This study investigated the Petroselinum crispum extract in hepatic steatosis in rats fed with fructose enriched diet. Rats were divided into the 4 groups: Group 1 rats received standard pellet diet with corn starch for the entire experimental period of 8 weeks. Group 2 rats received standard pellet diet and 2 gm/kg body weight crude Parsley leaf ethanol extract for the entire experimental period of 8 weeks. Group 3 rats received modified fructose diet. Group 4 rats received modified fructose diet and 2gm/kg crude Parsley leaf ethanol extract. Hepatic function and structure was evaluated in these rats. Modified fructose diet produced dyslipidemia, hepatic steatosis and infiltration of inflammatory cells in the liver and higher plasma hepatic markers. Petroselinum crispum extract reversed metabolic changes such as abnormal crispum extract attenuated chronic changes in modified fructose diet induced NAFLD (Tab. 2, Fig. 3, Ref. 43).

Dietary supplementation with essential fatty acids and polyunsaturated lecithin may improve biochemical and histological parameters in liver disease. Ten patients with serological and histological evidence of chronic hepatitis B received capsules of the polyunsaturated fatty acid-rich evening primrose oil in a dose of 4 g daily for 12 months, while a matched group received liquid paraffin capsules as a placebo. Compared to the placebo group, the patients receiving evening primrose oil showed no improvement in either biochemical or histological indices of liver damage, or in the rate of loss of circulating e antigen. Dietary, supplementation with this dose of essential fatty acids is unlikely to be of benefit in chronic hepatitis B.

In Hepatitis C virus (HCV) mono-infection, male sex is associated with faster liver fibrosis progression but the effects of sex have not been well studied in HIV-HCV co-infected patients. We examined the influence of sex on progression to significant liver fibrosis in HIV-HCV co-infected adults receiving antiretroviral therapy (ART) using the aspartate aminotransferase-to-platelet ratio index (APRI) as a surrogate biomarker of liver fibrosis. We evaluated 308 HIV infected, HCV RNA positive participants of a Canadian multicentre prospective cohort receiving antiretrovirals and without significant liver fibrosis or end-stage liver disease at baseline. We used multivariate discrete-time proportional hazards models to assess the effect of sex on time to significant fibrosis (APRI≥1.5) adjusting for baseline age, alcohol use, cigarette smoking, HCV duration, and APRI and time-updated CD4 count and HIV RNA. Overall, 55 (18%) participants developed an APRI ≥ 1.5 over 544 person-years of at-risk follow-up time; 18 (21%) women (incidence rate (IR)=14.0/100 PY; 7.5-20.4) and 37 (17%) men (IR=8.9/100 PY; 6.0-11.8). Women had more favourable profiles with respect to traditional risk factors for liver disease progression (younger, shorter duration of HCV infection and less alcohol use). Despite this, female sex was associated with a greater than two-fold increased risk of fibrosis progression (adjusted hazard rate (HR) =2.23; 1.22-4.08). HIV-HCV co-infected women receiving antiretroviral therapy were at significantly greater risk of progressing to liver fibrosis as measured by APRI compared with men. Enhanced efforts to engage and treat co-infected women for HCV are needed.

To establish and validate a simple quantitative assessment method for nonalcoholic fatty liver disease (NAFLD) based on a combination of the ultrasound hepatic/renal ratio and hepatic attenuation rate. A total of 170 subjects were enrolled in this study. All subjects were examined by ultrasound and (1)H-magnetic resonance spectroscopy ((1)H-MRS) on the same day. The ultrasound hepatic/renal echo-intensity ratio and ultrasound hepatic echo-intensity attenuation rate were obtained from ordinary ultrasound images using the MATLAB program. Correlation analysis revealed that the ultrasound hepatic/renal ratio and hepatic echo-intensity attenuation rate were significantly correlated with (1)H-MRS liver fat content (ultrasound hepatic/renal ratio: r = 0.952, P = 0.000; hepatic echo-intensity attenuation r = 0.850, P = 0.000). The equation for predicting liver fat content by ultrasound (quantitative ultrasound model) is: liver fat content (%) = 61.519 × ultrasound hepatic/renal ratio + 167.701 × hepatic echo-intensity attenuation rate -26.736. Spearman correlation analysis revealed that the liver fat content ratio of the quantitative ultrasound model was positively correlated with serum alanine aminotransferase, aspartate aminotransferase, and triglyceride, but negatively correlated with high density lipoprotein cholesterol. Receiver operating characteristic curve analysis revealed that the optimal point for diagnosing fatty liver was 9.15% in the quantitative ultrasound model. Furthermore, in the quantitative ultrasound model, fatty liver diagnostic sensitivity and specificity were 94.7% and 100.0%, respectively, showing that the quantitative ultrasound model was better than conventional ultrasound methods or the combined ultrasound hepatic/renal ratio and hepatic echo-intensity attenuation rate. If the (1)H-MRS liver fat content had a value < 15%, the sensitivity and specificity of the ultrasound quantitative model would be 81.4% and 100%, which still shows that using

Hepatitis E indigenous to economically developed countries: to what extent a zoonosis?

PubMed

Teo, Chong Gee

2006-10-01

Hepatitis E, a disease transmitted by hepatitis E virus, is increasingly recognized as being indigenous to affluent, temperate-zone countries. Issues pertaining to disease acquisition and hepatitis E virus infection, particularly in Western countries, are reviewed and highlighted. Clinical hepatitis E in the West, as in Japan, manifests more commonly in older people (>60 years) and in men, but fulminant hepatitis appears less frequent than in Japan. There, specific gastronomic and culinary risk factors associated with disease are being identified, but in the West, data implicating hepatitis E as being foodborne have yet to emerge. While hepatitis E virus subgenomic sequences in Western case patients are found to be closely related to swine hepatitis E virus, a porcine linkage to their infection remains to be established. Weak associations between occupational contact with pigs and risk of infection have been noted. Findings from earlier studies implicating animals that cohabitate with humans as reservoirs, and sewage as vehicles of infection await confirmation. Hepatitis E indigenous to developed countries is a distinct clinico-epidemiological entity. Humans, animals, food and the environment contribute and interact to cause human disease, and to sustain hepatitis E virus endemicity and enzooticity.

Co-infection with the hepatitis C virus (HCV) and/or hepatitis B virus (HBV) influences the morbidity and mortality of patients with HIV. A cross sectional analysis was of 11,032 HIV-infected patients enrolled in the Integrated HIV Care Program from May 2005 to April 2012 and Epi-info 3.5 was used to determine the serological prevalence of chronic hepatitis B and hepatitis C. The mean ± standard deviation age of patients was 36 ± 8.4 years (adult cohort) and 7 ± 3 years (paediatric cohort). The sero prevalence of hepatitis B surface antigen, hepatitis C (anti HCV antibodies) and triple infection are 8.7%, 5.3% and 0.35%, respectively. Men who have sex with men are at the highest risk of being co-infected with hepatitis B while intravenous drug users are at the highest risk of being co-infected with hepatitis C. It is important to screen for hepatitis B and C in HIV infected people in order to provide quality care for HIV patients with co-infection.

Background & Aims In the Netherlands, a selective hepatitis B virus (HBV) vaccination programme started in 2002 for men having sex with men, drug users, commercial sex workers and heterosexuals with frequent partner changes. We assessed the programme's effectiveness to guide policy on HBV prevention. Methods We analysed reports of acute HBV infection in the Netherlands between 2004 and 2010 requesting serum from patients for HBV-genome S- and C-region sequencing. We used coalescence analyses to assess genetic diversity of nonimported genotype-A cases over time. Results 1687 patients with acute HBV infection were reported between 2004 and 2010. The incidence of reported acute HBV infection decreased from 1.8 to 1.2 per 100,000 inhabitants, mostly due to a reduction in the number of cases in men who have sex with men. Men were overrepresented among cases with an unknown route of transmission, especially among genotype A2 cases mainly associated with transmission through male homosexual contact. The genetic diversity of nonimported genotype-A strains obtained from men who have sex with men decreased from 2006 onwards, suggesting HBV incidence in this group decreased. Conclusions The selective HBV-vaccination programme for behavioural high-risk groups very likely reduced the incidence of HBV infection in the Netherlands mainly by preventing HBV infections in men who have sex with men. A considerable proportion of cases in men who did not report risk behaviour was probably acquired through homosexual contact. Our findings support continuation of the programme, and adopting similar approaches in other countries where HBV transmission is focused in high-risk adults. PMID:23922651

Reactivation of hepatitis B virus (HBV) infection in asymptomatic hepatitis B surface antigen carriers undergoing chemotherapy or immunosuppressive therapy is a well-documented complication. However, data on the consequence of chemotherapy on the course of hepatitis C virus (HCV) infection in HCV+ patients have been controversial. Here, we review the current knowledge about the complications related to HCV in lymphoma patients receiving chemotherapy/immunosuppressive therapy. Although less frequent than HBV, these complications occur in a subset of patients with mortality rates up to 45%. Therefore, baseline screening for HBV and HCV before initiation of chemotherapy is crucial. High-risk patients having chronic active hepatitis, high baseline HCV viral load, HBV co-infection and receiving cytotoxic drugs, corticosteroids and rituximab (particularly if combined) should be closely monitored for serum transaminase, bilirubin and HCV RNA levels.

Background. An increasing incidence of anal cancer among men suggests a need to better understand anal canal human papillomavirus (HPV) infection among human immunodeficiency virus–negative men. Methods. Genotyping for HPV was conducted on cells from the anal canal among men who have sex with women (MSW) and men who have sex with men (MSM), aged 18–70 years, from Brazil, Mexico, and the United States. Factors associated with anal HPV infection were assessed using multivariable logistic regression. Results. The prevalence of any HPV type and oncogenic HPV types did not differ by city. Anal canal HPV prevalence was 12.2% among 1305 MSW and 47.2% among 176 MSM. Among MSW, reporting a lifetime number of ≥10 female sex partners, a primary sexual relationship <1 year in duration, and a prior hepatitis B diagnosis were independently associated with detection of any anal HPV in multivariable analysis. Among MSM, a younger age, reporting ≥2 male anal sex partners in the past 3 months, and never using a condom for anal sex in the past 6 months were independently associated with detection of any anal HPV in multivariable analysis. Conclusions. Number of sex partners was associated with anal HPV infection in both MSW and MSM. Anal HPV infection in men may be mediated by age, duration of sexual relationship, and condom use.

Objective The Hepatitis Testing and Linkage to Care (HepTLC) initiative promoted viral hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites from 2012 to 2014. Through the HepTLC initiative, the Minnesota Department of Health (MDH) and clinic partners began conducting linkage-to-care activities with hepatitis B-positive refugees in October 2012. This intervention provided culturally appropriate support to link refugees to follow-up care for hepatitis B. Methods MDH refugee health and viral hepatitis surveillance programs, along with clinics that screened newly arrived refugees in Hennepin and Ramsey counties in Minnesota, collaborated on the project, which took place from October 1, 2012, through September 30, 2014. Bilingual care navigators contacted refugees to provide education, make appointments, and arrange transportation. We compared the linkage-to-care rate for participants with the rates for refugees screened the year before project launch using a two-sample test of proportions. Results In the year preceding the project (October 2011 through September 2012), 87 newly arrived refugees had a positive hepatitis B surface antigen (HBsAg) test. Fifty-six (64%) refugees received follow-up care, 12 (14%) refugees did not receive follow-up care, and 19 (22%) refugees could not be located and had no record of follow-up care. During the project, 174 HBsAg-positive, newly arrived refugees were screened. Of those 174 refugees, 162 (93%) received follow-up care, seven (4%) did not receive follow-up care, and five (3%) could not be located and had no record of follow-up care. The one-year linkage-to-care rate for project participants (93%) was significantly higher than the rate for refugees screened the previous year (64%) (p<0.001). Conclusion In the context of a strong screening and surveillance infrastructure, a simple intervention improved the linkage-to-care rate for HBsAg-positive refugees. PMID:27168670

Approximately 240 million people are chronically infected with hepatitis B virus (HBV), 75% of whom reside in Asia. Approximately 600000 of infected patients die each year due to HBV-related diseases or hepatocellular carcinoma (HCC). The endemicity of hepatitis surface antigen in Indonesia is intermediate to high with a geographical difference. The risk of HBV infection is high in hemodialysis (HD) patients, men having sex with men, and health care workers. Occult HBV infection has been detected in various groups such as blood donors, HD patients, and HIV-infected individuals and children. The most common HBV subgenotype in Indonesia is B3 followed by C1. Various novel subgenotypes of HBV have been identified throughout Indonesia, with the novel HBV subgenotypes C6-C16 and D6 being successfully isolated. Although a number of HBV subgenotypes have been discovered in Indonesia, genotype-related pathogenicity has not yet been elucidated in detail. Therefore, genotype-related differences in the prognosis of liver disease and their effects on treatments need to be determined. A previous study conducted in Indonesia revealed that hepatic steatosis was associated with disease progression. Pre-S2 mutations and mutations at C1638T and T1753V in HBV/B3 have been associated with advanced liver diseases including HCC. However, drug resistance to lamivudine, which is prominent in Indonesia, remains obscure. Although the number of studies on HBV in Indonesia has been increasing, adequate databases on HBV infection are limited. We herein provided an overview of the epidemiology and clinical characteristics of HBV infection in Indonesia.

Hepatitis B virus (HBV) may reactivate when treating chronic hepatitis C (CHC) with direct acting antivirals (DAA). We aim to investigate the risk of HBV reactivation during DAA therapy. Chronic hepatitis C patients receiving pan-oral DAA therapy from December 2013 to August 2016 were evaluated. Fifty-seven patients that had a past HBV infection (negative hepatitis B surface antigen [HBsAg] and positive hepatitis B core antibody) and seven patients that had a current HBV infection (positive HBsAg) were enrolled. Serum HBV and hepatitis C virus (HCV) markers were regularly measured. The endpoints were the HCV sustained virological response (SVR) and the HBV virological/clinical reactivation. The overall SVR 12 rate was 96.9%, and two patients, one with positive HBsAg, had a relapse of HCV. No episodes of HBV virological reactivation were observed among the patients with a past HBV infection. For the seven patients with a current HBV infection, HBV virological reactivation was found in four (57.1%) of the seven patients. Clinical reactivation of HBV was observed in one patient with pretreatment detectable HBV DNA and recovered after entecavir administration. For the other three patients with HBV virological reactivation, the reappearance of low level HBV DNA without clinical reactivation was observed. HBsAg levels demonstrated only small fluctuations in all the patients. There was a minimal impact of hepatitis B core antibody seropositivity on HCV efficacy and safety. For CHC patients with current HBV infection, the risk of HBV reactivation was present, and monitoring the HBV DNA level during therapy is warranted. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Background Infection with hepatitis A and hepatitis B virus can increase the risk of morbidity and mortality in persons with chronic liver disease (CLD). The Advisory Committee on Immunization Practices recommends hepatitis A (HepA) and hepatitis B (HepB) vaccination for persons with CLD. Methods Data from the 2014 and 2015 National Health Interview Surveys (NHIS), nationally representative, in-person interview surveys of the non-institutionalized US civilian population, were used to assess self-reported HepA (≥1 and ≥2 doses) and HepB vaccination (≥1 and ≥3 doses) coverage among adults who reported a chronic or long-term liver condition. Multivariable logistic regression was used to identify factors independently associated with HepA and HepB vaccination among adults with CLD. Results Overall, 19.4% and 11.5% of adults aged ≥18 years with CLD reported receiving ≥1 dose and ≥2 doses of HepA vaccine, respectively, compared with 14.7% and 9.1% of adults without CLD (p<0.05 comparing those with and without CLD, ≥1dose). Age, education, geographic region, and international travel were associated with receipt of ≥2 doses HepA vaccine among adults with CLD. Overall, 35.7% and 29.1% of adults with CLD reported receiving ≥1 dose and ≥3 doses of HepB vaccine, respectively, compared with 30.2% and 24.7% of adults without CLD (p<0.05 comparing those with and without CLD, ≥1 dose). Age, education, and receipt of influenza vaccination in the past 12 months were associated with receipt of ≥3 doses HepB vaccine among adults with CLD. Among adults with CLD and ≥10 provider visits, only 13.8% and 35.3% had received ≥2 doses HepA and ≥3 doses HepB vaccine, respectively. Conclusions HepA and HepB vaccination among adults with CLD is suboptimal and missed opportunities to vaccinate occurred. Providers should adhere to recommendations to vaccinate persons with CLD to increase vaccination among this population. PMID:29395521

Hepatitis B antigen and viral hepatitis type B in India*

Surveys were conducted to determine the occurrence of overt hepatitis manifested by jaundice in groups of hospital patients who had survived their initial illness. Of those who had been given blood that had not been screened for the presence of hepatitis B antigen (HB Ag) 9.4% reported that they had had jaundice during the 6 months following transfusion. During a similar period jaundice was reported by only 1.1% of those who had received blood found to be negative for HB Ag by the cross-over electrophoresis test. This difference is highly significant. Jaundice was reported by 25.5% of recipients of HB Ag-positive blood. Of a control population of hospitalized but non-transfused patients 2.2% reported jaundice within 6 months of hospitalization. The risk of overt hepatitis from HB Ag in transfused blood is high in southern India and is similar to that in temperate countries where the occurrence of antigen carriers, and presumably of immune status, are lower than in the tropics.

In Brazil, approximately 130 new cases of hepatitis A per 100,000 inhabitants occur annually and 15% of the population has been in contact with hepatitis B virus. Portal hypertension causes hypersplenism and reduces T cell production, which may lead to less effective response to hepatitis vaccination. The objective of the study was to evaluate the response to hepatitis A and B vaccination in patients with portal hypertension secondary to chronic liver disease or portal vein thrombosis. Twenty-three patients (2 to 18 years) with portal hypertension seen at the Pediatric Hepatology Service of Hospital das Clínicas, Universidade Estadual de Campinas, between 1994 and 2006 were studied. Hepatitis A and B serology was tested in all patients. Patients who had not been vaccinated before their visits received the vaccines during the study period. Patients who had been vaccinated before but had negative anti-HB antibodies received a booster dose, and their serology was repeated Blood counts were performed in each patient to assess for immunosuppression. Eighteen patients received hepatitis A vaccine and all became positive for anti-HAV antibodies. All patients had received hepatitis B vaccine and 17 (73.9%) were anti-HBs positive at the time of the study The other 6 received a booster dose and became anti-HBs positive afterward. The anti-HBs-positive and -negative patients did not differ significantly in age, leukocytes, lymphocytes, or duration between the vaccination and positive serology. In this study, hepatitis A vaccines elicited a 100% response and hepatitis B vaccine conferred protection and induced an anamnestic response in pediatric patients with portal hypertension.

The aim of the current project was to develop an Internet-based recruitment system for HIV and sexually transmitted infection (STI) screening for men who have sex with men (MSM) in Estonia in order to collect biological samples during behavioural studies. In 2013, an Internet-based HIV risk-behaviour survey was conducted among MSM living in Estonia. After completing the questionnaire, all participants were offered anonymous and free-of-charge STI testing. They could either order a urine sample kit by post to screen for chlamydia infections (including lymphogranuloma venereum (LGV)), trichomoniasis, gonorrhoea and Mycoplasma genitalium infections, or visit a laboratory for HIV, hepatitis A virus, hepatitis B virus,hepatitis C virus and syphilis screening. Of 301 participants who completed the questionnaire, 265 (88%),reported that they were MSM. Of these 265 MSM,68 (26%) underwent various types of testing. In the multiple regression analysis, Russian as the first language,previous HIV testing and living in a city or town increased the odds of testing during the study. Linking Internet-based behavioural data collection with biological sample collection is a promising approach. As there are no specific STI services for MSM in Estonia,this system could also be used as an additional option for anonymous and free-of-charge STI screening.

We investigated the efficacy of entecavir, a cyclopentyl guanosine nucleoside analogue, as monoprophylaxis in patients with chronic hepatitis B who received a liver transplant. We studied data from 80 consecutive patients who received a liver transplant (47 from living donors and 33 from deceased donors) for hepatitis B-related disease and entecavir monotherapy as prophylaxis. None of the patients received hepatitis B immunoglobulin. Indications for transplant included decompensation from cirrhosis (27.5%), acute-on-chronic hepatitis B (47.5%), and hepatocellular carcinoma (25%). The median follow-up time was 26 months (range, 5-40 months). Before transplant, 33 patients were not on antiviral therapy and 47 were on oral therapy (18 had received less than 3 months of treatment). At the time of transplant, the median log HBV DNA level was 3.5 copies/mL (range, 1.54-8.81); 21 patients (26%) had undetectable levels of HBV DNA. The cumulative rate of hepatitis B surface antigen (HBsAg) loss was 86% and 91% after 1 and 2 years, respectively. Ten patients had reappearance of HBsAg. Eighteen patients (22.5%) were HBsAg positive at the time of their last examination; 17 of these had undetectable levels of HBV DNA, and the remaining patient had a low level of HBV DNA (217 copies/mL). There was no evidence of mutations at sites that confer resistance to entecavir among patients who were HBsAg positive. Although only 26% of patients had complete viral suppression at the time of transplant, 91% lost HBsAg, with 98.8% achieving undetectable levels of HBV DNA. A hepatitis B immunoglobulin-free regimen of entecavir monotherapy is effective after liver transplantation for chronic hepatitis B. Copyright © 2011 AGA Institute. Published by Elsevier Inc.

The efficacy of pegylated interferon (p-IFN) and ribavirin (RB) in transplant patients is not well known. Chronic hepatitis C evolves in a more aggressive form after transplantation, causing a worse survival. Twenty-one naïve patients with recurrent chronic hepatitis C demonstrated by biopsy were treated for 48 weeks with p-IFN alpha2b (1.5 microg/kg/wk) and RB (>10.6 mg/kg/d). Quantification of RNA was performed (Amplicor Cobas 2.0 Roche) at baseline, 4, 12, 24, 48, and 72 weeks. A qualitative technique was used when quantitative levels were undetectable. At more than 1 year since liver transplantation we did not detect coinfection with human immunodeficiency virus or use steroid treatment. Among the cohort there were 16 men (76.2%). The mean overall age was 52 +/- 12 years. Time from liver transplant to treatment was 1637 +/- 1030 days. They were all infected with genotype 1. Eight patients received cyclosporine and the others tacrolimus. One patient was coinfected with hepatitis B virus and was receiving lamivudine. The mean initial histological activity index was 6.9 +/- 1.5 and fibrosis, 2.52 +/- 1.8 (Ishak). Two patients needed spleen embolization before the treatment. Two patients had to stop the treatment: one due to clinical intolerance, and the other one due to a cholangitis. In 14%, p-IFN doses were adjusted. In 32% RB was adjusted. Five (23.8%) did not respond at 24 weeks. Fourteen (66.7%) showed end-treatment responses but four relapsed at 72 weeks. A sustained viral response was achieved in 9 (42.8%). One patient died due to arterial thrombosis just after completing the treatment.

Men who have sex with men (MSM) may benefit from human papillomavirus (HPV) vaccine due to increased risk for HPV infection and related disease. We assessed HPV vaccine acceptability and sexual experience prior to disclosure to Health Care Providers (HCP) to understand implications of targeted vaccination strategies for MSM. From July 2008 to February 2009, 1169 MSM aged ≥19 years were recruited at community venues in Vancouver. We assessed key variables from a self-administered questionnaire and independent predictors of HPV vaccine acceptability using multivariate logistic regression. Of 1041 respondents, 697 (67.0%) were willing to receive HPV vaccine and 71.3% had heard of HPV. Significant multivariate predictors of higher vaccine acceptability were (adjusted odds ratio [95% CI]): previous diagnosis of genital warts (1.7 [1.1, 2.6]), disclosure of sexual behavior to HCP (1.6 [1.1, 2.3]), annual income at least $20,000 (1.5 [1.1, 2.1]), previous hepatitis A or B vaccination (1.4 [1.0, 2.0]), and no recent recreational drug use (1.4 [1.0, 2.0]). Most MSM (78.7%) had disclosed sexual behavior to HCP and median time from first sexual contact with males to disclosure was 6.0 years (IQR 2-14 years); for men ≤26 years these were 72.0% and 3.0 years (IQR 1-8 years) respectively. Willingness to receive HPV vaccine was substantial among MSM in Vancouver; however, acceptability varied by demographics, risk, and health history. HPV vaccine programs delivered by HCP would offer limited benefit given the duration of time from sexual debut to disclosure to HCP. Crown Copyright © 2012. Published by Elsevier Ltd.

Many new and existing cases of viral hepatitis infections are related to injection drug use. Transmission of these infections can result directly from the use of injection equipment that is contaminated with blood containing the hepatitis B or C virus or through sexual contact with an infected individual. In the latter case, drug use can indirectly contribute to hepatitis transmission through the dis-inhibited at-risk behavior, that is, unprotected sex with an infected partner. Individuals who inject drugs are at-risk for infection from different hepatitis viruses, hepatitis A, B, or C. Those with chronic hepatitis B virus infection also face additional risk should they become co-infected with hepatitis D virus. Protection from the transmission of hepatitis viruses A and B is best achieved by vaccination. For those with a history of or who currently inject drugs, the medical management of viral hepatitis infection comprising screening, testing, counseling and providing care and treatment is evolving. Components of the medical management of hepatitis infection, for persons considering, initiating, or receiving pharmacologic therapy for opioid addiction include: testing for hepatitis B and C infections; education and counseling regarding at-risk behavior and hepatitis transmission, acute and chronic hepatitis infection, liver disease and its care and treatment; vaccination against hepatitis A and B infection; and integrative primary care as part of the comprehensive treatment approach for recovery from opioid abuse and dependence. In addition, participation in a peer support group as part of integrated medical care enhances treatment outcomes. Liver disease is highly prevalent in patient populations seeking recovery from opioid addiction or who are currently receiving pharmacotherapy for opioid addiction. Pharmacotherapy for opioid addiction is not a contraindication to evaluation, care, or treatment of liver disease due to hepatitis virus infection. Successful

Recent studies reveal that the rate of normal on-treatment alanine aminotransferase (ALT) appears different for different nucleos(t)ide analogues (NAs); yet its clinical significance is unclear. We aimed to evaluate the impact of normal on-treatment ALT during antiviral treatment with entecavir (ETV) or tenofovir disoproxil fumarate (TDF) in patients with chronic hepatitis B (CHB). A territory-wide cohort of patients with CHB who received ETV and/or TDF in 2005-2016 was identified. Serial on-treatment ALT levels were collected and analyzed. Normal on-treatment ALT (ALT-N) was defined as ALT <30 U/L in males and <19 U/L in females. The primary and secondary outcomes were composite hepatic events (including hepatocellular carcinoma) based on diagnostic codes. Patients with hepatic events before or during the first year of antiviral treatment or follow-up <1 year were excluded. A total of 21,182 patients with CHB (10,437 with and 10,745 without ALT-N at 12 months after antiviral treatment) were identified and followed for 4.0 ± 1.7 years. Patients with and without ALT-N differed in baseline ALT (58 vs. 61 U/L), hepatitis B virus DNA (4.9 vs. 5.1 log10 IU/ml) and cirrhosis status (8.8% vs. 10.5%). A total of 627 (3.0%) patients developed composite hepatic events. Compared to no ALT-N, ALT-N at 3, 6, 9 and 12 months reduced the risk of hepatic events, after adjustment for baseline ALT and other important covariates, with adjusted hazard ratios (95% CI) of 0.61 (0.49-0.77), 0.55 (0.45-0.67), 0.54 (0.44-0.65) and 0.51 (0.42-0.61) respectively (all p <0.001). The cumulative incidence (95% CI) of composite hepatic events at six years was 3.51% (3.06%-4.02%) in ALT-N and 5.70% (5.15%-6.32%) in the no ALT-N group (p <0.001). Normal on-treatment ALT is associated with a lower risk of hepatic events in patients with CHB receiving NA treatment, translating into improved clinical outcomes in these patients.

The currently low endemic level of hepatitis A in Spain favors manifestation of the disease as outbreaks among specific risk groups. The aim of this study is to analyze the hepatitis A outbreaks investigated in Catalonia (Spain) during the period of 1999 to 2003. The criteria for including an outbreak were defined and outbreaks were classified according to the type of transmission. The variables analyzed were space, time, socio-demographic parameters, setting, risk factors, and preventive measures adopted. The incidence rate and rate ratio were calculated according to age and sex. Among 74 outbreaks, 73 fulfilled the inclusion criteria. Most outbreaks involved person-to-person transmission (83.8%) and the rest had a common source of infection (14.9%). In total, 334 cases were included (cumulative incidence 1999-2003: 5.27 per 100,000 inhabitants), with an average age of 24.5 years. The settings yielding the most cases were family (143), community (97) and schools/preschools (87). The number of cases per outbreak ranged from 2 to 11, except one outbreak that occurred in 83 young homosexual men with high-risk sexual practices. The main factors related to the case index or to coprimary cases included belonging to age groups with low immunity (children and young adults) and travelling to or from endemic areas. Hepatitis A outbreaks in Catalonia are still frequent. They mainly occur in the family environment, by person-to-person transmission and in the most vulnerable groups (preschool or school employees, travelers, and men who perform high-risk sexual practices with other men).

HIV-infected men who have sex with men (HIV-MSM) are at high risk of hepatitis C virus (HCV) infection. This study aimed to compare risk factors between HIV-MSM coinfected with HCV and those who are not, in a national representative survey conducted in France. The ANRS VESPA2 survey (April 2011-January 2012) collected sociodemographic and behavioural data (through face-to-face administered questionnaires) as well as medical data (physician questionnaire) among 3022 HIV-infected adults recruited in 73 French HIV hospital departments. We identified behavioural correlates of HCV coinfection among sexually active HIV-MSM who participated in VESPA2 (logistic regression models). Ninety-three of the 1037 HIV-MSM of the study population (8.9%) were coinfected with HCV. The following risk factors were independently associated with HCV coinfection, after adjustment for age and time since HIV diagnosis: current or past injecting drug use, having had at least 20 male sexual partners during the previous 12 months, reporting inconsistent condom use during anal sex with casual partners, and attending sex parties. Individuals reporting at least three sexual risk factors were at the highest risk of being coinfected with HCV (OR (95% CI): 22.86 (9.74; 53.62), p<0.0001). HIV-MSM reporting several sexual risk factors should be sensitised to risk-reduction behaviours to avoid HCV transmission to sexual partners, and infection or reinfection with HCV.

Alcoholic hepatitis is a clinical syndrome characterized by jaundice and liver impairment that occurs in patients with a history of heavy and prolonged alcohol use. The short-term mortality among patients with severe disease exceeds 30%. Prednisolone and pentoxifylline are both recommended for the treatment of severe alcoholic hepatitis, but uncertainty about their benefit persists. We conducted a multicenter, double-blind, randomized trial with a 2-by-2 factorial design to evaluate the effect of treatment with prednisolone or pentoxifylline. The primary end point was mortality at 28 days. Secondary end points included death or liver transplantation at 90 days and at 1 year. Patients with a clinical diagnosis of alcoholic hepatitis and severe disease were randomly assigned to one of four groups: a group that received a pentoxifylline-matched placebo and a prednisolone-matched placebo, a group that received prednisolone and a pentoxifylline-matched placebo, a group that received pentoxifylline and a prednisolone-matched placebo, or a group that received both prednisolone and pentoxifylline. A total of 1103 patients underwent randomization, and data from 1053 were available for the primary end-point analysis. Mortality at 28 days was 17% (45 of 269 patients) in the placebo-placebo group, 14% (38 of 266 patients) in the prednisolone-placebo group, 19% (50 of 258 patients) in the pentoxifylline-placebo group, and 13% (35 of 260 patients) in the prednisolone-pentoxifylline group. The odds ratio for 28-day mortality with pentoxifylline was 1.07 (95% confidence interval [CI], 0.77 to 1.49; P=0.69), and that with prednisolone was 0.72 (95% CI, 0.52 to 1.01; P=0.06). At 90 days and at 1 year, there were no significant between-group differences. Serious infections occurred in 13% of the patients treated with prednisolone versus 7% of those who did not receive prednisolone (P=0.002).

Patients with chronic hepatitis C virus (HCV) are at increased risk for complications of liver disease if they become infected with the hepatitis A (HAV) or hepatitis B (HBV) viruses. The authors examined the rates of testing for HAV, HBV, and HCV, as well as rates of vaccination against HAV and HBV in patients with chronic HCV in a random sample (N = 207) of medical records of patients enrolled in a methadone maintenance program. Almost all patients reviewed were tested for HAV, HBV, and HCV. Of the 111 patients with chronic HCV, 53 (48.6%) and 68 (63%) lacked immunity to HAV and HBV, respectively. Of those lacking immunity, 29 (54.7%) and 2 (2.9%) were vaccinated for HAV and HBV, respectively. Despite high rates of testing for HAV, HBV, and HCV at a methadone maintenance program, approximately half of those with chronic HCV eligible for the HAV vaccine received it, and few of those eligible for HBV vaccine received it.

Despite a high prevalence of hepatitis C virus (HCV) among drug users, HCV evaluation and treatment acceptance are extremely low among these patients when referred from drug treatment facilities for HCV management. We sought to increase HCV treatment effectiveness among patients from a methadone maintenance treatment program (MMTP) by maintaining continuity of care. We developed, instituted and retrospectively assessed the effectiveness of an integrated, co-localized care model in which an internist-addiction medicine specialist from MMTP was embedded in the hepatitis clinic. Methadone maintenance treatment program patients were referred, evaluated by the internist and hepatologist in hepatitis clinic and provided HCV treatment with integration between both sites. Of 401 evaluated patients, anti-HCV antibody was detected in 257, 86% of whom were older than 40 years. Hepatitis C virus RNA levels were measured in 222 patients, 65 of whom were aviremic. Of 157 patients with detectable HCV RNA, 125 were eligible for referral to the hepatitis clinic, 76 (61%) of whom accepted and adhered with the referral. Men engaged in MMTP <36 months were significantly less likely to be seen in hepatitis clinic than men in MMTP more than 36 months (odds ratio = 7.7; 95% confidence interval 2.6-22.9) or women. We evaluated liver histology in 63 patients, and 83% had moderate to advanced liver disease. Twenty-four patients initiated treatment with 19 completing and 13 (54%) achieving sustained response. In conclusion, integrated care between the MMTP and the hepatitis clinic improves adherence with HCV evaluation and treatment compared to standard referral practices. © 2010 Blackwell Publishing Ltd.

Background: Sentinel surveillance reported high human immunodeficiency virus positivity rates among men who have sex with men. The current study has described the high-risk behavior and self-reported sexually transmitted infection(s) among self-identified men who have sex with men. Aims: The present study was to find out the extent of high-risk behavior and prevalence of self-reported sexually transmitted diseases among self-identified men who have sex with men, registered with selected nongovernmental organizations in Delhi. Materials and Methods: A facility-based cross-sectional study was done among 250 men who have sex with men during March 2009 to February 2010, through consecutive sampling strategy. Results: Majority (80%) were anal-receptive, received money for sex (61%) and were involved in all types of sexual intercourse with men (oral-86%, manual-97%, and anal-94%). Consistent condom use with male partner was low (46%), most common reason (52%) for not using condom was, that either the condoms were not available or the partner objected. Self-reported sexually transmitted infection(s) was 41% in the past 12 months. Conclusions: This study underscores the increased vulnerability of men who have sex with men of Delhi and need for sustained interventions. PMID:24251268

A cross sectional survey was performed to investigate the epidemic of human immunodeficiency virus (HIV), hepatitis C virus (HCV), syphilis, and HIV-1 subtype infections among men who have sex with men (MSM) and to evaluate factors that were correlated with sexually transmitted infections (STIs) among 657 MSM in Zhenjiang, Jiangsu, during 2012-2013. Data on socio-demographic parameters and risky behaviors were collected, and blood samples were obtained. In this survey, the prevalence of STIs due to HIV (5.3%), HCV (0.6%), and syphilis (19.2%) were measured. Of 35 HIV-infected MSM, 1 (0.2%) and 17 (2.6%) were co-infected with HCV and syphilis. Among 33 samples with available HIV-1 genomic fragment sequences, 6.1% B, 72.7% CRF01_AE, and 21.2% CRF07_BC were identified. Multivariate logistic regression analysis showed that age > 30 years (odds ratio [OR] 2.002; 95% confidence interval [CI], 1.144-3.502) and having had STI symptoms in the past year (OR, 11.673; 95% CI, 3.092-44.078) were positively correlated with having an STI, while consistent use of a condom when having sex with male partners (OR, 0.621; 95% CI, 0.408-0.945) was significantly associated with a low STI rate. The worsening epidemic of HIV, HCV, and syphilis infections, and the prevalence of complex subtypes of HIV-1 and other risk factors suggest that effective intervention strategies should be strengthened for MSM in Zhenjiang, Jiangsu.

The rare hepatitis B virus (HBV) genotype G (HBV/G) coinfects HIV-1-positive individuals along with HBV/A and generates recombinants. However, the circulation of HBV A/G recombinants remains poorly understood. This molecular epidemiologic study examined HBV A/G recombinants in Japanese HIV-1-positive men who have sex with men (MSM). Initially, blood specimens submitted for confirmatory tests of HIV infection in Osaka and Tokyo, Japan, from 2006 to 2013 were examined for HIV-1, and HIV-1-positive specimens were screened for HBV. Among 817 specimens from HIV-1-positive individuals, HBsAg was detected in 59 specimens; of these, HBV/Ae (alternatively A2), a subgenotype of HBV/A prevalent in Europe and North America, was identified in 70.2%, HBV/C in 17.5%, and HBV/G in 10.5%, and HBV/E in 1.8% according to the core gene sequence. The full-length genome analysis of HBV was performed on HBV/G-positive specimens because some HBV A/G recombinants were historically overlooked by genotyping based on a partial genome analysis. It revealed that five of the specimens contained novel Ae/G recombinants, the core gene of which had a high sequence similarity to HBV/G. Detailed analyses showed that novel recombinants were coinfected with HBV/Ae in a recombinant-dominant fashion. No major drug-resistant mutations were found in the newly identified HBV Ae/G recombinants. Some of the individuals asymptomatically coinfected with HIV/HBV suffered mild liver injury. This study demonstrated that novel Ae/G HBV recombinants were identified in Japanese HIV-1-positive MSM. The pathogenicity of novel HBV Ae/G recombinants should be examined in a future longitudinal study. Surveillance of such viruses in HIV-1-positive individuals should be emphasized.

During an outbreak of hepatitis A predominantly among men who have sex with men (MSM) in Copenhagen, Denmark, in 2004, we did a case-control study to determine risk factors for infection. A case was an MSM >17 years, living in Copenhagen, with IgM positive hepatitis A infection diagnosed between June and August 2004, and without a household contact with a hepatitis A case before onset of illness. Controls were selected at the Copenhagen Pride Festival. The study included 18 cases and 64 controls. Sixteen of 18 cases and 36/63 controls had sex with casual partners (ORMH 5.6, 95% CI 1.2-26.9). Eleven of 18 cases and 14/62 controls had sex in gay saunas (ORMH 4.2, 95% CI 1.5-11.5). Sex at private homes appeared to be protective (ORMH 0.2, 95% CI 0.1-0.7). Casual sex including sex in gay saunas was an important risk factor for the spread of HAV among MSM in Copenhagen. The results are in accordance with findings in other European outbreaks. As the general immunity to hepatitis A decreases and the outbreak potential increases, we recommend health education and hepatitis A vaccination to all MSM not living in monogamous relationships, especially if they visit gay saunas or other places with frequent partner change. To stop spread of hepatitis A among MSM in Europe, a European consensus on prevention and control measures may be required.

To evaluate the hepatitis B immunization status of female sex workers (FSWs) in Central-West Brazil and to evaluate their compliance with and immune response to hepatitis B vaccination delivered using outreach strategies. A total of 721 FSWs recruited in 2 large cities in Central-West Brazil were interviewed and screened for the presence of hepatitis B virus (HBV) markers. Hepatitis B vaccine was offered to all women susceptible to HBV, using outreach strategies. The immune response of FSWs who received a full course of vaccine was assessed following the final vaccine dose. We found that 27.6% of FSWs, the majority of whom were aged 18 to 25 years, had serological evidence of previous hepatitis B vaccination. A total of 434 FSWs were eligible for vaccination, 389 (89.6%) of whom accepted the first hepatitis B vaccine dose. Of those, 64% received a second dose and 37.5% received all three doses. Through the outreach strategy, there was a 52.2% increase in the number of women who received the second dose and a 67% increase in the number who received the third dose. Of the 146 women who received a full course of vaccine, 105 accepted testing for quantitative anti-HBs (hepatitis B surface antibody) following the final vaccine dose, and 92.4% of those tested had developed protective levels of anti-HBs. Lower education level, workplace, and length of prostitution were predictors of full-vaccine acceptance. The present findings illustrate the benefits of using outreach strategies to overcome the difficulties of vaccinating hard-to-reach populations such as FSWs.

Fulminant hepatic failure is a life-threatening disease. Hepatitis A virus (HAV) can cause fulminant hepatic failure and death in about 0.2% of cases. Extensive destruction of infected hepatocytes by immune-mediated lysis is thought to be the cause. We aimed to evaluate the use of steroid therapy in children with fulminant HAV. This study included 33 children with fulminant HAV in two groups. Steroid group: comprised of 18 children who received prednisolone (1 mg/kg/d) or its equivalent dose of methylprednisolone, and the nonsteroid group: comprised another 15 children who did not receive steroid therapy. Age and sex were matched for both groups (P > .05), and they were comparable regarding baseline clinical and laboratory characteristics. Of the steroid group, 15 patients survived and 3 died, while in the nonsteroid group, 4 patients survived and 11 died (P = .001). Of the living patients, 15 of 19 (78.9%) received steroids while only 3 of 14 (21.4%) of the dead patients received steroids (P = .001). Stepwise regression analysis showed that steroid therapy was the only independent variable associated with recovery (P = .001). Steroid therapy in children with fulminant HAV associated significantly with improved outcome and survival. Future studies on a larger population size are strongly recommended. © 2018 John Wiley & Sons Ltd.

Gender inequality: Bad for men's health.

PubMed

Cornell, M

2013-01-01

Men's increased risk of death in ART programmes in sub-Saharan Africa is widely reported but poorly understood. Some studies have attributed this risk to men's poorer health-seeking behaviour, which may prevent them from accessing ART, being adherent to treatment, or remaining in care. In a multicentre analysis of 46 201 adults starting ART in urban and rural settings in South Africa, these factors only partly explained men's increased mortality while receiving ART. Importantly, the gender difference in mortality among patients receiving ART (31% higher for men than women) was substantially smaller than that among HIV-negative South Africans, where men had twice the risk of death compared with women. Yet, this extreme gender inequality in mortality, both within and outside of ART programmes, has not given rise to widespread action. Here it is argued that, despite their dominance in society, men may be subject to a wide range of unfair discriminatory practices, which negatively affect their health outcomes. The health needs of men and boys require urgent attention.

The liver is the intra-abdominal organ more injured in patient victims of trauma. The injury occurs more frequently in the penetrating trauma. The incidence of mortality for injuries of the liver is 10%. To evaluate the mortality of the patients with hepatic trauma, the treatment applied and its evolution. Were analyzed, retrospectively, the charts of all patients with hepatic trauma and surgical indication. Were analyzed: gender, age, ISS (injury severity score), classification of the abdominal trauma type (open or closed), causing instrument of the open traumas, degree of the injury, hepatic segments involved, presence of associated injuries, type of surgical treatment: not-therapeutic laparotomy and therapeutic laparotomy, reoperations, complications, time of hospitalization in days and mortality. One hundred and thirty-seven patients participated. Of these, 124 were men (90.5%). The majority (56.2%) had 20-29 years old. Closed abdominal trauma was most prevalent (67.9%). Of the penetrating traumas, the originated with firearms were in 24.8%. One hundred and three patients had only one injured hepatic segment (75.2%) and 34 (24.8%) two. Grade II injuries were in 66.4%. Of the 137 patients with laparotomy, 89 had been not-therapeutic, while in 48 it was necessary to repair associated injuries. Spleen and diaphragm had been the more frequently injured structures, 30% and 26%, respectively. The ISS varied of eight to 72, being the ISS > 50 (eight patients) associate with fatal evolution (five patients). Biliary fistula and hepatic abscess had been the main complications. Seven deaths had occurred. Concomitant injuries, hepatic and other organs, associated with ISS > 50 presented higher possibility of complications and death.

Early tumour shrinkage has been associated with improved survival in patients receiving cetuximab-based systemic chemotherapy for liver metastases from colorectal cancer (LM-CRC). We tested this hypothesis for previously treated LM-CRC patients receiving cetuximab (500 mg/m 2 ) and triplet hepatic artery infusion (HAI) within European trial OPTILIV. Irinotecan (180 mg/m 2 ), 5-fluorouracil (2800 mg/m 2 ) and oxaliplatin (85 mg/m 2 ) were given as chronomodulated or conventional delivery. Patients were retrospectively categorised as early responders (complete or partial RECIST response after three courses) or non-early responders (late or no response). Prognostic factors were determined using multivariate logistic or Cox regression models. Response was assessed in 57 of 64 registered patients (89%), who had previously received one to three prior systemic chemotherapy protocols. An early response occurred at 6 weeks in 16 patients (28%; 9 men, 7 women), aged 33-76 years, with a median of 12 liver metastases (LMs) (2-50), involving five segments (1-8). Ten patients had a late response, and 31 patients had no response. Grade 3-4 fatigue selectively occurred in the non-early responders (0% versus 26%; p = 0.024). Early tumour response was jointly predicted by chronomodulation-odds ratio (OR): 6.0 (1.2-29.8; p = 0.029)-and LM diameter ≤57 mm-OR: 5.3 (1.1-25.0; p = 0.033). Early tumour response predicted for both R0-R1 liver resection-OR: 11.8 (1.4-100.2; p = 0.024) and overall survival-hazard ratio: 0.39 (0.17-0.88; p = 0.023) in multivariate analyses. Early tumour response on triplet HAI and systemic cetuximab predicted for complete macroscopic liver resection and prolonged survival for LM-CRC patients within a multicenter conversion-to-resection medicosurgical strategy. Confirmation is warranted for early response on HAI to guide decision making. Protocol numbers: EUDRACT 2007-004632-24 NCT00852228. Copyright © 2016 Elsevier Ltd. All rights reserved.

Acute hepatitis A is a fecal-oral transmitted disease related to inadequate sanitary conditions. In addition to its traditional classification, several outbreaks in the men who have sex with men (MSM) population have resulted in acute hepatitis A being recognized as a sexually transmitted disease. However, few studies have clarified the clinical manifestations in these outbreaks involving the MSM population. Beginning in June 2015, there was an outbreak of acute hepatitis A involving the MSM population in Northern Taiwan. We conducted a 15-year retrospective study by recruiting 207 patients with the diagnosis of acute hepatitis A that included the pre-outbreak (January 2001 to May 2015) and outbreak (June 2015 to August 2016) periods in a tertiary medical center in Northern Taiwan. Using risk factors, comorbidities, presenting symptoms, laboratory test results and imaging data, we aimed to evaluate the clinical significance of acute hepatitis A in the MSM population, where human immunodeficiency virus (HIV) coinfection is common. There was a higher prevalence of reported MSM (p < 0.001), HIV (p < 0.001) and recent syphilis (p < 0.05) coinfection with acute hepatitis A during the outbreak period. The outbreak population had more prominent systemic symptoms, was more icteric with a higher total bilirubin level (p < 0.05) and had a 7-times higher tendency (p < 0.05) to have a hepatitis A relapse. The clinical course of acute hepatitis A during an outbreak involving the MSM and HIV-positive population is more symptomatic and protracted than in the general population.

Background In Hepatitis C virus (HCV) mono-infection, male sex is associated with faster liver fibrosis progression but the effects of sex have not been well studied in HIV-HCV co-infected patients. We examined the influence of sex on progression to significant liver fibrosis in HIV-HCV co-infected adults receiving antiretroviral therapy (ART) using the aspartate aminotransferase-to-platelet ratio index (APRI) as a surrogate biomarker of liver fibrosis. Methods We evaluated 308 HIV infected, HCV RNA positive participants of a Canadian multicentre prospective cohort receiving antiretrovirals and without significant liver fibrosis or end-stage liver disease at baseline. We used multivariate discrete-time proportional hazards models to assess the effect of sex on time to significant fibrosis (APRI≥1.5) adjusting for baseline age, alcohol use, cigarette smoking, HCV duration, and APRI and time-updated CD4 count and HIV RNA. Results Overall, 55 (18%) participants developed an APRI ≥ 1.5 over 544 person-years of at-risk follow-up time; 18 (21%) women (incidence rate (IR)=14.0/100 PY; 7.5-20.4) and 37 (17%) men (IR=8.9/100 PY; 6.0-11.8). Women had more favourable profiles with respect to traditional risk factors for liver disease progression (younger, shorter duration of HCV infection and less alcohol use). Despite this, female sex was associated with a greater than two-fold increased risk of fibrosis progression (adjusted hazard rate (HR) =2.23; 1.22-4.08). Conclusions HIV-HCV co-infected women receiving antiretroviral therapy were at significantly greater risk of progressing to liver fibrosis as measured by APRI compared with men. Enhanced efforts to engage and treat co-infected women for HCV are needed. PMID:26090666

Pre-exposure prophylaxis (PrEP) with daily oral emtricitabine and tenofovir disoproxil fumarate (FTC/TDF) prevents HIV infection. The safety and feasibility of HIV PrEP in the setting of hepatitis B virus (HBV) infection were evaluated. The Iniciativa Profilaxis Pre-Exposición study randomized 2499 HIV-negative men and transgender women who have sex with men to once-daily oral FTC/TDF versus placebo. Hepatitis serologies and transaminases were obtained at screening and at the time PrEP was discontinued. HBV DNA was assessed by polymerase chain reaction, and drug resistance was assessed by population sequencing. Vaccination was offered to individuals susceptible to HBV infection. Of the 2499 participants, 12 (0.5%; including 6 randomized to FTC/TDF) had chronic HBV infection. After stopping FTC/TDF, 5 of the 6 participants in the active arm had liver function tests performed at follow-up. Liver function tests remained within normal limits at post-stop visits except for a grade 1 elevation in 1 participant at post-stop week 12 (alanine aminotransferase = 90, aspartate aminotransferase = 61). There was no evidence of hepatic flares. Polymerase chain reaction of stored samples showed that 2 participants in the active arm had evidence of acute HBV infection at enrollment. Both had evidence of grade 4 transaminase elevations with subsequent resolution. Overall, there was no evidence of TDF or FTC resistance among tested genotypes. Of 1633 eligible for vaccination, 1587 (97.2%) received at least 1 vaccine; 1383 (84.7%) completed the series. PrEP can be safely provided to individuals with HBV infection if there is no evidence of cirrhosis or substantial transaminase elevation. HBV vaccination rates at screening were low globally, despite recommendations for its use, yet uptake and efficacy were high when offered.

Hepatitis E and Pregnancy- Understanding the pathogenesis

2008-01-01

Hepatitis E virus (HEV) is a single-stranded RNA virus that causes large-scale epidemics of acute viral hepatitis, particularly in developing countries. In men and non pregnant women, the disease is usually self-limited and has a case-fatality rate of less than <0.1%. However in pregnant women particularly from certain geographic areas in India, HEV infection is more severe, often leading to fulminant hepatic failure and death in a significant proportion of patients. In contrast, reports from Egypt, Europe and the USA have shown that the course and severity of viral hepatitis during pregnancy is not different from that in non-pregnant women. The reasons for this geographical difference are not clear. The high mortality rate in pregnancy has been thought to be secondary to the associated hormonal (estrogen and progesterone) changes during pregnancy and consequent immunological changes. These immunological changes include down regulation of p65 component of NF κB with a predominant Th2 bias in the T-cell response along with host susceptibility factors, mediated by HLA expression. Thus far, researchers were unable to explain the high HEV morbidity in pregnancy, why it is different from other hepatitis viruses such as hepatitis A with similar epidemiological features, and the reason behind the difference in HEV morbidity in pregnant women in different geographical regions. The recent developments in understanding the immune response to HEV have encouraged us to review possible mechanisms for these differences. Further research in the immunology of HEV and pregnancy is required to conquer this disease in the near future. PMID:18662274

Each VLDL contains apoB-100 and variable amounts of apolipoproteins E and C, cholesterol and triglycerides. To determine whether baseline lipid levels predicted treatment outcome. Retrospective analysis was performed of 250 chronic hepatitis C (CHC) patients who had received anti-viral agents interferon-alpha and ribavirin; 165 had a sustained virological response (SVR). Pre- and post-treatment nonfasting lipid profiles were measured and non-high-density lipoprotein (non-HDL) cholesterol (i.e. apoB-associated) was calculated. Binary logistic regression analysis assessed factors independently associated with treatment outcome. There was an independent association between higher apoB-associated cholesterol (non-HDL-C) and increased odds of SVR (odds ratio 2.09, P = 0.042). In multivariate analysis, non-HDL-C was significantly lower in HCV genotype 3 (g3) than genotype 1 (P = 0.007); this was reversible upon eradication of HCVg3 (pre-treatment non-HDL-C = 2.8 mmol/L, SVR = 3.6 mmol/L, P < 0.001). Higher apoB-associated cholesterol is positively associated with treatment outcome in CHC patients receiving anti-viral therapy, possibly due to competition between apoB-containing lipoproteins and infectious low-density HCV lipo-viral particles for hepatocyte entry via shared lipoprotein receptors.

hepatitis vaccination, 35% had been tested for syphilis during the past 12 months, and 18% had participated in an individual- or group-level HIV behavioral intervention. MSM in the United States continue to engage in sexual and drug-use behaviors that increase the risk for HIV infection. Although many MSM had been tested for HIV infection, many had not received hepatitis vaccinations or syphilis testing, and only a small proportion had recently participated in a behavioral intervention. To reduce HIV infection among MSM, additional effort is needed to decrease the number of men who are engaging in risk behaviors while increasing the number who recently have been tested for HIV. The National HIV/AIDS Strategy for the United States delineates a coordinated response to reduce infections and HIV-related health disparities among MSM and other disproportionately affected groups. NHBS data can be used to monitor progress toward the goals of the national strategy and to guide national and local planning efforts to maximize the impact of HIV prevention programs.

Hepatitis C virus (HCV) infection is a major health problem in Egypt as the nation bears the highest prevalence rate worldwide. This necessitated establishing a novel model of care (MOC) to contain the epidemic, deliver patient care and ensure global treatment access. In this review, we describe the process of development of the Egyptian model and future strategies for sustainability. Although the magnitude of the HCV problem was known for many years, the HCV MOC only came into being in 2006 with the establishment of the National Committee for Control of Viral Hepatitis (NCCVH) to set up and implement a national control strategy for the disease and other causes of viral hepatitis. The strategy outlines best practices for patient care delivery by applying a set of service principles through identified clinical streams and patient flow continuums. The Egyptian national viral hepatitis treatment programme is considered one of the most successful and effective public health programmes. To date, more than one million patients were evaluated and more than 850 000 received treatment under the umbrella of the programme since 2006. The NCCVH has been successful in establishing a strong infrastructure for controlling viral hepatitis in Egypt. It established a nationwide network of digitally connected viral hepatitis-specialized treatment centres covering the country map to enhance treatment access. Practice guidelines suiting local circumstances were issued and regularly updated and are applied in all affiliated centres. This review illustrates the model and the successful Egyptian experience. It sets an exemplar for states, organizations and policy-makers setting up programmes for care and management of people with hepatitis C. © 2017 John Wiley & Sons Ltd.

Hepatitis E virus (HEV) usually causes self-limiting acute liver infections from fecal or oral transmission, though other routes of infection exist (vertical transmission, blood transfusion, zoonosis). It may give rise to fulminant hepatic failure in 1% of cases. Cases have recently been reported of chronic infection evolving to cirrhosis in immunosuppressed patients, such as those with a liver or kidney transplant. Nonetheless, development of acute liver failure in these patients is exceptional, with few cases published. We present a case of acute liver failure due to HEV in a liver transplant patient who required a liver retransplant 9 years after receiving the original transplant. Copyright © 2017 Elsevier Inc.

BackgroundNotified cases of hepatitis E have increased 40-fold in the past 10 years in Germany. Food safety is a major concern as hepatitis E virus (HEV) RNA has been detected in ready-to-eat retail-level food products. The objective of this case-control study was to assess risk factors for autochthonous symptomatic hepatitis E and explore reasons for delays in diagnosis. Methods: Demographic, clinical and exposure data from notified hepatitis E cases and individually matched population controls were collected in semi-standardised telephone interviews. Conditional logistic regression analysis was used to calculate matched odds ratios (mOR) and population attributable fractions (PAF). Results: In total, 270 cases and 1,159 controls were included (mean age 53 years, 61% men in both groups). Associated with disease were: consumption of undercooked pork liver, pork, wild boar meat, frankfurters, liver sausage and raw vegetables; contact with waste water (occupational) and various host factors (mORs between 1.9 and 34.1, p value < 0.03). PAF for frankfurters and liver sausage were 17.6%, and 23.6%, respectively. There were statistically significant differences in the clinical presentation and hospitalisation proportion of acute hepatitis E in men and women. Diagnosis was preceded by more invasive procedures in 29.2% of patients, suggesting that hepatitis E was not immediately considered as a common differential diagnosis. Conclusions: Our study suggests that there are indeed sex-specific differences in disease development and lends important epidemiological evidence to specific ready-to-eat pork products as a major source for autochthonous hepatitis E. A review of existing consumer recommendations and production methods may be indicated.

Hepatitis B testing is recommended for immigrants from countries where hepatitis B infection is endemic. However, only about one-half of Chinese in North America have received hepatitis B testing. We conducted a randomized controlled trial to evaluate the effectiveness of a hepatitis B lay health worker intervention for Chinese Americans/Canadians. Four hundred and sixty individuals who had never been tested for hepatitis B were identified from community-based surveys of Chinese conducted in Seattle, Washington, and Vancouver, British Columbia. These individuals were randomly assigned to receive a hepatitis B lay health worker intervention or a direct mailing of physical activity educational materials. Follow-up surveys were completed 6 months after randomization. Self-reported hepatitis B testing was verified through medical records review. A total of 319 individuals responded to the follow-up survey (69% response rate). Medical records data verified hepatitis B testing since randomization for 9 (6%) of the 142 experimental group participants and 3 (2%) of the 177 control group participants (P = 0.04). At follow-up, a higher proportion of individuals in the experimental arm than individuals in the control arm knew that hepatitis B can be spread by razors (P < 0.001) and during sexual intercourse (P = 0.07). Our findings suggest that lay health worker interventions can impact hepatitis B-related knowledge. However, our hepatitis B lay health worker intervention had a very limited impact on hepatitis B testing completion. Future research should evaluate other intervention approaches to improving hepatitis B testing rates among Chinese in North America.

Hepatitis A vaccines are highly immunogenic in healthy patients, but there is uncertainty about their immunogenicity in immunocompromised patients. Our study included immunocompromised patients who received 1 or 2 hepatitis A vaccinations between January 2011 and June 2013. We assessed factors that influenced the serologic response to vaccination. We performed a literature review of previous studies on hepatitis A vaccination in immunocompromised patients. Of 85 immunocompromised patients, 65 used immunosuppressive drugs, 13 had received stem cell transplants, and 7 were infected with human immunodeficiency virus. After vaccination, 65 of 85 (76.5%) developed antibodies. Tumor necrosis factor α blocker use was associated with better serologic responses than other immunosuppressive drugs. Female patients were more compliant than male patients with postvaccination antibody titer measurements. In 11 relevant studies, antibody responses after the first and second vaccination averaged 37% and 82%, respectively. Factors that negatively influenced serologic response rates were high doses of immunosuppressive drugs, fewer hepatitis A vaccinations, and a short interval between vaccination and antibody measurement. Immunocompromised patients showed moderate to good serologic responses to hepatitis A vaccination, but may need more time to develop immunity. Tumor necrosis factor α blocker use was associated with better antibody responses than other drugs. Specifically, male patients should be motivated to return for antibody titer measurements. © The Author 2015.

Cinnamon contains cumarin, which may be toxic to the liver. EU-regulations standardardize the amount of cinnamon in pastry including cinnamon rolls. The aim of the study was to investigate if cinnamon intake from pastry was associated with toxic or alcoholic hepatitis. We registered 58 patients with toxic hepatitis, 38 (66%) women and 20 (34%) men with a median age of 51 (range: 32-80) and 53 (range: 18-78) years, respectively. A total of 22 patients had primarily cholestasis and 36 had hepatitis biochemically. The duration of toxic liver disease from admission to normalization of liver enzymes was similar in the two groups (3.5 ± 3.5 vs 3.6 ± 3.5 months). Toxic hepatitis was most often caused by drugs e.g. NSAID (n = 15; 26%), antibiotics (n = 9; 16%), alternative medicine (n = 7; 12%) and Antabuse (n = 5; 9%). We registered eight patients admitted with severe alcoholic hepatitis, five men and three women, median age of 60 (range: 34-67) years. Alcoholic hepatitis was associated with high alcohol intake. None of the patients with toxic or alcoholic hepatitis reported of excessive intake of cinnamon rolls and there was no evidence of cinnamon added to alcohol of alternative medicine products. Intake of cinnamon from cinnamon rolls is not associated with admission for toxic or alcoholic hepatitis. However, for the diagnosis of toxic liver diseases including alcohol it is very important to have patient information regarding any new drugs, alternative medicine and alcohol intake. Further, other causes of liver diseases should be excluded. not relevant. not relevant.

Nationwide surveys of intractable disease patients receiving public financial aid for treatment were performed by Research Committee for Epidemiology of Intractable Disease (Ministry of Health and Welfare, Japan) 4 times in the past, in 1984, 1988, 1992 and 1997. The purpose of the present study was to clarify the features of continuance with intractable disease patients receiving public financial aid for treatment. Individual information collected by each nationwide survey was linked using the disease, the residence, the sex, and the birth date. The proportion of intractable disease patients according to receipt duration, kind of medical insurance, sex and age was calculated with reference to the disease and an estimation of the receipt persistence rate was calculated for every year. Moreover, in consideration of variation in the data, average receipt persistence rates over years were also calculated. According to observation on individual patient's follow up, the proportion for which financial aid was discontinued within four years was 25%, while 70% continued receiving aid for at least four years and some 55% for eight or nine years. The proportion of those who continue receiving support long-term is high about the so-called autoimmune diseases, such as systemic lupus erythematosus, Behçet's disease, and the aortic syndrome. In contrast, with diseases having a poor prognosis, such as fulminant hepatitis, amyloidosis, and amyotrophic lateral sclerosis, periods of continuance are short. The proportion needing long-term continuation is higher in women than in men, especially with diseases which have long been eligible for support. However, with diseases for which receipt was started recently, there is a tendency for persistence to be higher in men than in women. With reform of insurance systems, including the medical system for intractable diseases, it is predicted that receipt continuation will change with alteration of social factors, and it is necessary to

Viral hepatitis is responsible for great health, social and economic burden both globally and in the UK. This study aimed to assess the research funding awarded to UK institutions for viral hepatitis research and the relationship of funded research to clinical and public health burden of viral hepatitis. Databases and websites were systematically searched for information on infectious disease research studies funded for the period 1997-2010. Studies specifically related to viral hepatitis research were identified and categorized in terms of funding by pathogen, disease and by a research and development value chain describing the type of science. The overall data set included 6165 studies (total investment £2.6 billion) of which £76.9 million (3.0%) was directed towards viral hepatitis across 323 studies (5.2%). By pathogen, there were four studies specifically investigating hepatitis A (£3.8 million), 69 studies for hepatitis B (21.4%) with total investment of £14.7 million (19.1%) and 236 (73.1%) hepatitis C studies (£62.7 million, 81.5%). There were 4 studies investigating hepatitis G, and none specifying hepatitis D or E. By associated area, viral hepatitis and therapeutics research received £17.0 million, vaccinology £3.1 million and diagnostics £2.9 million. Preclinical research received £50.3 million (65.4%) across 173 studies, whilst implementation and operational research received £19.4 million (25.3%) across 128 studies. The UK is engaged in much hepatology research, but there are areas where the burden is great and may require greater focus, such as hepatitis E, development of a vaccine for hepatitis C, and further research into hepatitis-associated cancers. Private sector data, and funding information from other countries, would also be useful in priority setting. © 2014 The Authors. Journal of Viral Hepatitis Published by John Wiley & Sons Ltd.

Submassive hepatic necrosis induced by dichloropropanol.

A hitherto undescribed industrial liver injury of fulminant form induced by dichloropropanol is reported. Two middle-aged men developed severe hepatic injury just after cleaning a dichloropropanol tank at a plant producing dichloropropanol. They died from hepatic failure 4 and 11 days respectively, after carrying out the work. Liver specimens taken at autopsy from one of the cases showed submassive hepatic necrosis. This accident prompted us to undertake an experimental study in rats of intraperitoneal one-shot injection of two isomeric substances of dichloropropanol, that is, 2,3-dichloro-1-propanol (DC1P) and 1,3-dichloro-2-propanol (DC2P). Saline was injected into the control rats. One, two, four, six, 24, 48, 72 h, and 1 week after the injection, rats in each group were sacrificed. Neither control nor DC1P-injected rats showed significant biochemical or histopathological abnormalities. DC2P-injected rats revealed elevations of transaminase from 6 h after the injections, and submassive necrosis of the liver was observed in many rats. It was concluded that the severe liver injuries in both the human cases and rats in our study were caused by DC2P.

Adefovir dipivoxil (ADV) is effective for hepatitis B virus (HBV) infection; however, ADV may provoke renal injury resulting in osteomalacia, and this side effect is seldom recognized until bone fractures emerge. We herein present a 66-year-old woman with HBV infection who received ADV for 6 years. Although she exhibited no sign of bone fractures, her urinary β-2 microglobulin (β2MG) level increased to 83,837 μg/L and scintigraphy revealed minimal fractures of the third rib. ADV was subsequently reduced and her urinary β2MG rapidly fell to 3,637 μg/L. Conversely, her urinary N-acetyl-β-D-glucosaminidase, and serum phosphate, alkaline phosphatase levels did not respond.

OBJECTIVE One-third of men with type 2 diabetes have hypogonadotropic hypogonadism (HH). We conducted a randomized placebo-controlled trial to evaluate the effect of testosterone replacement on insulin resistance in men with type 2 diabetes and HH. RESEARCH DESIGN AND METHODS A total of 94 men with type 2 diabetes were recruited into the study; 50 men were eugonadal, while 44 men had HH. Insulin sensitivity was calculated from the glucose infusion rate (GIR) during hyperinsulinemic-euglycemic clamp. Lean body mass and fat mass were measured by DEXA and MRI. Subcutaneous fat samples were taken to assess insulin signaling genes. Men with HH were randomized to receive intramuscular testosterone (250 mg) or placebo (1 mL saline) every 2 weeks for 24 weeks. RESULTS Men with HH had higher subcutaneous and visceral fat mass than eugonadal men. GIR was 36% lower in men with HH. GIR increased by 32% after 24 weeks of testosterone therapy but did not change after placebo (P = 0.03 for comparison). There was a decrease in subcutaneous fat mass (−3.3 kg) and increase in lean mass (3.4 kg) after testosterone treatment (P < 0.01) compared with placebo. Visceral and hepatic fat did not change. The expression of insulin signaling genes (IR-β, IRS-1, AKT-2, and GLUT4) in adipose tissue was significantly lower in men with HH and was upregulated after testosterone treatment. Testosterone treatment also caused a significant fall in circulating concentrations of free fatty acids, C-reactive protein, interleukin-1β, tumor necrosis factor-α, and leptin (P < 0.05 for all). CONCLUSIONS Testosterone treatment in men with type 2 diabetes and HH increases insulin sensitivity, increases lean mass, and decreases subcutaneous fat. PMID:26622051

ABSTRACT Objective: To characterize a chronic hepatitis B cohort based on initial and follow-up clinical evaluations. Methods: A retrospective and descriptive analysis of clinical and laboratory data from chronic HBsAg adult carriers, without HIV, unexposed to treatment, with at least two outpatient visits, between February 2006 and November 2012. Fisher´s exact test, χ², Wilcoxon, Spearman, multiple comparisons and Kappa tests were applied, the level of significance adopted was 5%, with a 95% confidence interval. Results: 175 patients with mean age of 42.95±12.53 years were included: 93 (53.1%) were men, 152 (86.9%) were negative for hepatitis B e-antigen (HBeAg), 3 (1.7%) had hepatitis C coinfection, 15 (8.6%) had cirrhosis, and 2 (1.1%) had hepatocellular carcinoma. Genotype A predominated. Sixty-six patients (37.7%) had active hepatitis, 6 (3.4%) presented immune tolerance, and 38 (21.7%) were inactive carriers. Exacerbations and/or viral breakthrough were detected in 16 patients (9.1%). In 32 patients (18.3%), hepatitis B virus DNA remained persistently elevated and alanine aminotransferase levels were normal, whereas in 17 (9.7%), there was low hepatitis B virus DNA and alterated alanine aminotransferase. If only initial alanine aminotransferase and hepatitis B virus DNA values were considered, 15 cases of active hepatitis would not have been detected. Advanced fibrosis was more common in HBeAg-positive patients, and it was significantly associated with transaminases, hepatitis B virus DNA, and age. Conclusion: Many patients had active hepatitis, but almost 25%, who were HBeAg non-reactive, were only identified because of combined analyses of the hepatitis B virus DNA and transaminases levels, sometimes associated with histological data, after clinical follow-up.

To evaluate whether a hepatic fibrosis index (HFI), quantified on the basis of hepatic contour abnormality, is a risk factor for the development of hepatocellular carcinoma (HCC) in patients with chronic hepatitis C. Our institutional review board approved this retrospective study and written informed consent was waved. During a 14-month period, consecutive 98 patients with chronic hepatitis C who had no medical history of HCC treatment (56 men and 42 women; mean age, 70.7 years; range, 48-91 years) were included in this study. Gadoxetic acid-enhanced hepatocyte specific phase was used to detect and analyze hepatic contour abnormality. Hepatic contour abnormality was quantified and converted to HFI using in-house proto-type software. We compared HFI between patients with (n=54) and without HCC (n=44). Serum levels of albumin, total bilirubin, aspartate transferase, alanine transferase, percent prothrombin time, platelet count, alpha-fetoprotein, protein induced by vitamin K absence-II, and HFI were tested as possible risk factors for the development of HCC by determining the odds ratio with logistic regression analysis. HFIs were significantly higher in patients with HCC (0.58±0.86) than those without (0.36±0.11) (P<0.001). Logistic analysis revealed that only HFI was a significant risk factor for HCC development with an odds ratio (95% confidence interval) of 26.4 (9.0-77.8) using a cutoff value of 0.395. The hepatic fibrosis index, generated using a computer-aided assessment of hepatic contour abnormality, may be a useful imaging biomarker for the prediction of HCC development in patients with chronic hepatitis C.

Vaccination, screening, and linkage to care can reduce the burden of chronic hepatitis B virus (HBV) infection. However, recommendations vary among organizations, and their implementation has been suboptimal. The American College of Physicians' High Value Care Task Force and the Centers for Disease Control and Prevention developed this article to present best practice statements for hepatitis B vaccination, screening, and linkage to care. A narrative literature review of clinical guidelines, systematic reviews, randomized trials, and intervention studies on hepatitis B vaccination, screening, and linkage to care published between January 2005 and June 2017 was conducted. Clinicians should vaccinate against hepatitis B virus (HBV) in all unvaccinated adults (including pregnant women) at risk for infection due to sexual, percutaneous, or mucosal exposure; health care and public safety workers at risk for blood exposure; adults with chronic liver disease, end-stage renal disease (including hemodialysis patients), or HIV infection; travelers to HBV-endemic regions; and adults seeking protection from HBV infection. Clinicians should screen (hepatitis B surface antigen, antibody to hepatitis B core antigen, and antibody to hepatitis B surface antigen) for HBV in high-risk persons, including persons born in countries with 2% or higher HBV prevalence, men who have sex with men, persons who inject drugs, HIV-positive persons, household and sexual contacts of HBV-infected persons, persons requiring immunosuppressive therapy, persons with end-stage renal disease (including hemodialysis patients), blood and tissue donors, persons infected with hepatitis C virus, persons with elevated alanine aminotransferase levels (≥19 IU/L for women and ≥30 IU/L for men), incarcerated persons, pregnant women, and infants born to HBV-infected mothers. Clinicians should provide or refer all patients identified with HBV (HBsAg-positive) for posttest counseling and hepatitis B-directed care.

Ochs, A

2011-07-01

Acute hepatic vascular complications are rare. Acute portal vein thrombosis (PVT) and the Budd-Chiari syndrome (BSC) are the leading causes. Coagulopathy and local factors are present in up to 80% of cases. Diagnosis is established by colour-coded Doppler sonography, contrast-enhanced computed tomography or magnetic resonance imaging. Patients with acute PVT present with abdominal pain and disturbed intestinal motility. In the absence of cirrhosis anticoagulation with heparin is established followed by oral anticoagulation. In severe cases, surgical thrombectomy or transjugular thrombolysis with stent shunt may be necessary. Acute or fulminant BCS may require emergency liver transplantation or a transjugular intrahepatic portosystemic stent shunt, if patients present with acute liver failure. Milder cases receive anticoagulation for thrombolysis of occluded hepatic veins. Sinusoidal obstruction syndrome (SOS) is diagnosed after total body irradiation or chemotherapy, the term SOS replacing the former veno-occlusive disease. The treatment of congenital vascular malformations, complications in the setting of OLTX as well as patients with hepatic involvement of hereditary hemorrhagic telangiectasia requires significant expertise in a multidisciplinary approach.

Coinfection with hepatitis A virus (HAV) or hepatitis B virus (HBV) in patients with chronic hepatitis C virus (HCV) is associated with increased morbidity and mortality. The Center for Medicare and Medicaid Services has identified HAV and HBV vaccination as a priority area for quality measurement in HCV. It is unclear to what extent patients with HCV meet these recommendations. We used national data from the Department of Veterans Affairs HCV Clinical Case Registry to evaluate the prevalence and predictors of meeting the quality measure (QM) of receiving vaccination or documented immunity to HAV and HBV in patients with chronic HCV. We identified 88,456 patients who had overall vaccination rates of 21.9% and 20.7% for HBV and HAV, respectively. The QM rates were 57.0% and 45.5% for HBV and HAV, respectively. Patients who were nonwhite or who had elevated alanine aminotransferase levels, cirrhosis, or human immunodeficiency virus were more likely to meet the HBV QM. Factors related to HCV care were also determinants of meeting the HBV QM. These factors included receiving a specialist consult, genotype testing, or HCV treatment. Patients who were older, had psychosis, and had a higher comorbidity score were less likely to meet the HBV QM. With a few exceptions, similar variables were related to meeting the HAV QM. The incidence of superinfection with acute HBV and HAV was low, but it was significantly lower in patients who received vaccination than in those who did not. Quality measure rates for HAV and HBV are suboptimal for patients with chronic HCV. In addition, several patient-related factors and receiving HCV-related care are associated with a higher likelihood of meeting QMs. Copyright © 2010 American Association for the Study of Liver Diseases.

Hepatic secretion of VLDL fatty acids during stimulated lipogenesis in men.

PubMed

Aarsland, A; Wolfe, R R

1998-06-01

Fatty acids (FA) that are utilized for triglyceride (TG) synthesis in the liver and principally from two sources: FA synthesized de novo in the liver and preformed FA. We have measured the contribution from the two sources to very low density lipoprotein (VLDL) TG synthesis individually for palmitate, oleate, stearate, and linoleate (approximately 98% of the total FA of VLDL TG (VLDL TGFA)) by isotopomer analysis. Five healthy men were studied in the basal state, and 1 (day 1) and 4 days (day 4) after the start of a hypercaloric carbohydrate-enriched diet (approximately 2.5 times energy expenditure). The secretion of de novo palmitate was increased 15- and 43-fold after 1 and 4 days of hyperalimentation (2.6+/-1.2 (basal state), 40.8+/-20.0 (day 1), and 113.3+/-42.0 micromol/kg per d (day 4)). Even though 4 days of hyperalimentation increased the secretion of de novo stearate 43-fold and de novo oleate 70-fold (stearate; 0.2+/-0.2 (basal), 8.6+/-3.3 micromol/kg per d (day 4), oleate; 0.4+/-0.4 (basal), 28.2+/-12.7 micromol/kg per d (day 4)), palmitate accounted for 75-85% of all the de novo VLDL TGFA. One day of carbohydrate hyperalimentation tended to decrease the secretion while 4 days increased the secretion of all preformed FA in VLDL TG. The rate of secretion of preformed palmitate and oleate were almost identical (palmitate; 80.2+/-22.2 (basal), 45.1+/-23.8 (day 1), and 256.2+/-74.1 micromol/kg per d (day 4), oleate; 95.2+/-22.8 (basal), 46.2+/-24.2 (day 1), and 356.8+/-74.1 micromol/kg per d (day 4)) and collectively these two FA accounted for 80-90% of the secretion from the preformed source. Palmitate is the predominant product of acute and prolonged carbohydrate mediated lipogenesis in the human liver. The pathway of further elongation and subsequent desaturation of de novo synthesized palmitate to generate stearate and oleate is inducible but, quantitatively, of minor significance in hepatic lipogenesis.

Clinical and virological factors associated with hepatitis B virus reactivation in HBsAg-negative and anti-HBc antibodies-positive patients undergoing chemotherapy and/or autologous stem cell transplantation for cancer.

We studied clinical outcome and clinico-virological factors associated with hepatitis B virus reactivation (HBV-R) following cancer treatment in hepatitis B virus surface antigen (HBsAg)-negative/anti-hepatitis B core antibodies (anti-HBcAb)-positive patients. Between 11/2003 and 12/2005, HBV-R occurred in 7/84 HBsAg-negative/anti-HBcAb-positive patients treated for haematological or solid cancer. Virological factors including HBV genotype, core promoter, precore, and HBsAg genotypic and amino acid (aa) patterns were studied. Patients presenting with reactivation were men, had an hepatitis B virus surface antibody (HBsAb) titre <100 IU/L and underwent >1 line of chemotherapy (CT) significantly more frequently than controls. All were treated for haematological cancer, 3/7 received haematopoietic stem cell transplantation (HSCT), and 4/7 received rituximab. Using multivariate analysis, receiving >1 line of CT was an independent risk factor for HBV-R. Fatal outcome occurred in 3/7 patients (despite lamivudine therapy in two), whereas 2/4 survivors had an HBsAg seroconversion. HBV-R involved non-A HBV genotypes and core promoter and/or precore HBV mutants in all cases. Mutations known to impair HBsAg antigenicity were detected in HBV DNA from all seven patients. HBV DNA could be retrospectively detected in two patients prior cancer treatment and despite HBsAg negativity. HBV-R is a concern in HBsAg-negative/anti-HBcAb-positive patients undergoing cancer therapy, especially in males presenting with haematological cancer, a low anti-HBsAb titre and more than one chemotherapeutic agent. HBV DNA testing is mandatory to improve diagnosis and management of HBV-R in these patients. The role of specific therapies such as rituximab or HSCT as well as of HBV aa variability deserves further studies. © 2009 Blackwell Publishing Ltd.

Two open-label, single-dose, parallel-group studies were conducted to characterize the pharmacokinetics of the novel antibacterial tedizolid and the safety of tedizolid phosphate, its prodrug, in renally or hepatically impaired subjects. Tedizolid pharmacokinetics in subjects with severe renal impairment without dialysis support was compared with that of matched control subjects with normal renal function. Effects of hemodialysis on tedizolid pharmacokinetics were determined in a separate cohort of subjects undergoing long-term hemodialysis. Effects of hepatic impairment on tedizolid pharmacokinetics were determined in subjects with moderate or severe hepatic impairment and compared with those of matched control subjects with normal hepatic function. Each participant received a single oral (hepatic impairment) or intravenous (renal impairment) dose of tedizolid phosphate at 200 mg; hemodialysis subjects received two doses (separated by 7 days), before and after dialysis, in a crossover fashion. The pharmacokinetics of tedizolid was similar in subjects with severe renal impairment and controls (∼8% lower area under the concentration-time curve [AUC], with a nearly identical peak concentration) and in subjects undergoing hemodialysis before and after tedizolid phosphate administration (∼9% lower AUC, with a 15% higher peak concentration); <10% of the dose was removed during 4 h of hemodialysis. Tedizolid pharmacokinetics was only minimally altered in subjects with moderate or severe hepatic impairment; the AUC was increased approximately 22% and 34%, respectively, compared with that of subjects in the control group. Tedizolid phosphate was generally well tolerated in all participants. These results suggest that tedizolid phosphate dose adjustments are not necessary in patients with any degree of renal or hepatic impairment.

Immune Responses to HCV and Other Hepatitis Viruses

PubMed Central

Park, Su-Hyung; Rehermann, Barbara

2014-01-01

Summary Five human hepatitis viruses cause most acute and chronic liver disease worldwide. Over the past 25 years hepatitis C virus (HCV) in particular has received much interest because of its ability to persist in most immunocompetent adults and the lack of a protective vaccine. Here we examine innate and adaptive immune responses to HCV infection. Although HCV activates an innate immune response, it employs an elaborate set of mechanisms to evade interferon (IFN)-based antiviral immunity. By comparing innate and adaptive immune responses to HCV with those to hepatitis A and B viruses, we suggest that prolonged innate immune activation impairs the development of successful adaptive immune responses. Comparative immunology furthermore provides insights into the maintenance of immune protection. We conclude by discussing prospects for an HCV vaccine and future research needs for the hepatitis viruses. PMID:24439265

Pregnant women with an elevated viral load of hepatitis B virus (HBV) have a risk of transmitting infection to their infants, despite the infants' receiving hepatitis B immune globulin. In this multicenter, double-blind clinical trial performed in Thailand, we randomly assigned hepatitis B e antigen (HBeAg)-positive pregnant women with an alanine aminotransferase level of 60 IU or less per liter to receive tenofovir disoproxil fumarate (TDF) or placebo from 28 weeks of gestation to 2 months post partum. Infants received hepatitis B immune globulin at birth and hepatitis B vaccine at birth and at 1, 2, 4, and 6 months. The primary end point was a hepatitis B surface antigen (HBsAg)-positive status in the infant, confirmed by the HBV DNA level at 6 months of age. We calculated that a sample of 328 women would provide the trial with 90% power to detect a difference of at least 9 percentage points in the transmission rate (expected rate, 3% in the TDF group vs. 12% in the placebo group). From January 2013 to August 2015, we enrolled 331 women; 168 women were randomly assigned to the TDF group and 163 to the placebo group. At enrollment, the median gestational age was 28.3 weeks, and the median HBV DNA level was 8.0 log 10 IU per milliliter. Among 322 deliveries (97% of the participants), there were 319 singleton births, two twin pairs, and one stillborn infant. The median time from birth to administration of hepatitis B immune globulin was 1.3 hours, and the median time from birth to administration of hepatitis B vaccine was 1.2 hours. In the primary analysis, none of the 147 infants (0%; 95% confidence interval [CI], 0 to 2) in the TDF group were infected, as compared with 3 of 147 (2%; 95% CI, 0 to 6) in the placebo group (P=0.12). The rate of adverse events did not differ significantly between groups. The incidence of a maternal alanine aminotransferase level of more than 300 IU per liter after discontinuation of the trial regimen was 6% in the TDF group and 3% in

Previous studies have shown that plasma free choline concentrations are significantly decreased in many long-term home total parenteral nutrition (TPN) patients. Furthermore, low choline status has been associated with both hepatic morphologic and hepatic aminotransferase abnormalities. A preliminary pilot study suggested choline-supplemented TPN may be useful in reversal of these hepatic abnormalities. Fifteen patients (10 M, 5 F) who had required TPN for > or =80% of their nutritional needs were randomized to receive their usual TPN (n = 8), or TPN to which 2 g choline chloride had been added (n = 7) for 24 weeks. Baseline demographic data were similar between groups. Patients had CT scans of the liver and spleen, and blood for plasma free and phospholipid-bound choline, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, gamma glutamyl transferase (GGT), bilirubin, serum lipids, complete blood count (CBC), and chemistry profile obtained at baseline, and weeks 2, 4, 6, 12, 16, 20, 24, and 34. CT scans were analyzed for Hounsfield unit (HU) densities. There were no significant differences in any measured parameters after 2 weeks. However, at 4 weeks, a significant difference in liver HU between groups was observed (13.3+/-5.0 HU [choline] vs 5.8+/-5.2 HU [placebo], p = .04). This significant trend continued through week 24. Recurrent hepatic steatosis and decreased HU were observed at week 34, 10 weeks after choline supplementation had been discontinued. A significant increase in the liver-spleen differential HU was also observed in the choline group (10.6+/-6.2 HU [choline] vs 1.3+/-3.3 HU [placebo], p = .01). Serum ALT decreased significantly (p = .01 to .05) in the choline group vs placebo at weeks 6,12, 20, and 24. Serum AST was significantly decreased in the choline group by week 24 (p = .02). The serum alkaline phosphatase was significantly reduced in the choline group at weeks 2, 12, 20, 24, and 34 (p = .02 to 0

Hepatitis B vaccine has been shown to be highly efficient in preventing hepatitis B. However, 5%-10% of individuals fail to develop protective levels (>or=10 mIU/mL) of antibodies to hepatitis B surface antigen (anti-HBs) and are considered to be nonresponders. A total of 48 nonresponders and 20 subjects naive to the HBV vaccine received a double dose of combined hepatitis A and B vaccine (Twinrix) at 0, 1, and 6 months. The levels of anti-HBs and antibodies to hepatitis A virus (anti-HAV) were determined before vaccination and 1 month after each dose. Among 44 nonresponders, protective anti-HBs levels were found in 26 (59%) after the first dose and in 42 (95%) after the third dose. Among the control subjects, the corresponding figures were 10% and 100%, respectively. All subjects seroconverted to anti-HAV. The titers of both anti-HBs and anti-HAV were lower in the previously nonresponsive subjects (P< .01). Revaccination of nonresponders to the standard hepatitis B vaccine regimen with a double dose of the combined hepatitis A and B vaccine was highly effective. This is most likely explained by the increased dose, a positive bystander effect conferred by the hepatitis A vaccine, or both.

Raloxifene, a selective estrogen receptor modulator, has been used extensively for osteoporosis. In addition to the effect of osteoporosis treatment, emerging evidences show that raloxifene affects the vascular function in different tissues. Cirrhosis is characterized with portal hypertension and complicated with hepatic encephalopathy. Portal hypertension affects portal-systemic shunt which leads to hepatic encephalopathy that the vascular modulation might influence severity of hepatic encephalopathy. Herein, we evaluated the impact of raloxifene on bile duct ligation (BDL)-induced cirrhotic rats. The female Sprague-Dawley rats received BDL plus ovariectomy or sham-operation. Four weeks later, rats were divided into 2 subgroups respectively to receive of raloxifene (10mg/kg/day) or saline (vehicle) for 14 days. On the 43th day, motor activities and hemodynamic parameters were measured. Hepatic and vascular mRNA and protein expressions were determined. The histopathological change of liver was examined. We found that the liver biochemistry, ammonia level and motor activity were similar between cirrhotic rats with or without raloxifene administration. The hemodynamic parameters were not significantly different except that raloxifene reduced portal venous inflow. Raloxifene exacerbated hepatic fibrosis and up-regulated hepatic endothelin-1 and cyclooxygenase 2 protein expressions. In addition, raloxifene modulated the mRNA expressions of endothelial nitric oxide synthase, cyclooxygenase and endothelin-1 in the superior mesenteric artery and collateral vessel. In conclusion, raloxifene aggravates hepatic fibrosis and decreases portal venous inflow in cirrhotic rats without adversely affecting portal hypertension and hepatic encephalopathy. The modulation of hepatic and vascular endothelin-1, endothelial nitric oxide synthase and cyclooxygenase expressions may play a role in the mechanism. Copyright © 2017 Elsevier B.V.

Injection drug use is the most common transmission route for hepatitis C. High rates of infection are observed among individuals on opioid agonist therapy. Although people who inject drugs carry the highest burden, few have initiated treatment. We present a comprehensive review of the evidence on the efficacy of HCV medications, drug-drug interactions, and barriers to and models of care. Studies have demonstrated comparable efficacy for individuals who are on opioid agonist therapy compared with those who are not. We propose that a strategy of treatment and cure-as-prevention is imperative in this population to curb the hepatitis C epidemic. Copyright © 2018 Elsevier Inc. All rights reserved.

Direct-acting antiviral agents (DAAs) are used increasingly to treat hepatitis C virus (HCV) infection. Reports were published recently on hepatitis B virus (HBV) reactivation (HBV-R) in patients with HBV-HCV co-infection. Hepatitis B virus reactivation, defined as an abrupt increase in HBV replication in patients with inactive or resolved HBV infection, may result in clinically significant hepatitis. To assess whether HBV-R is a safety concern in patients receiving HCV DAAs. Descriptive case series. U.S. Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). 29 patients with HBV-R receiving HCV DAAs. Clinical and laboratory data. The FDA identified 29 unique reports of HBV-R in patients receiving DAAs from 22 November 2013 to 15 October 2016. Two cases resulted in death and 1 case in liver transplantation. Patients in whom HBV-R developed were heterogeneous regarding HCV genotype, DAAs received, and baseline HBV characteristics. At baseline, 9 patients had a detectable HBV viral load, 7 had positive results on hepatitis B surface antigen (HBsAg) testing and had an undetectable HBV viral load, and 3 had negative results on HBsAg testing and had an undetectable HBV viral load. For the remaining 10 patients, data points were not reported or the data were uninterpretable. Despite provider knowledge of baseline HBV, HBV-R diagnosis and treatment were delayed in 7 cases and possibly 7 others. The quality of information varied among reports. Because reporting is voluntary, HBV-R associated with DAAs likely is underreported. Hepatitis B virus reactivation is a newly identified safety concern in patients with HBV-HCV co-infection treated with DAAs. Patients with a history of HBV require clinical monitoring while receiving DAA therapy. Studies would help determine the risk factors for HBV-R, define monitoring frequency, and identify patients who may benefit from HBV prophylaxis and treatment. DAAs remain a safe and highly effective treatment for the

Eighty percent of patients who receive bariatric surgery are women, yet the majority of preclinical studies are in male rodents. Because sex differences drive hepatic gene expression and overall lipid metabolism, we sought to determine whether sex differences were also apparent in these endpoints in response to bariatric surgery. Two cohorts of age-matched virgin male and female Long-Evans rats were placed on a high fat diet for 3 weeks and then received either Sham or vertical sleeve gastrectomy (VSG), a surgery which resects 80% of the stomach with no intestinal rearrangement. Each sex exhibited significantly decreased body weight due to a reduction in fat mass relative to Sham controls ( p  < 0.05). Microarray and follow-up qPCR on liver revealed striking sex differences in gene expression after VSG that reflected a down-regulation of hepatic lipid metabolism and an up-regulation of hepatic inflammatory pathways in females vs. males after VSG. While the males had a significant reduction in hepatic lipids after VSG, there was no reduction in females. Ad lib -fed and fasting circulating triglycerides, and postprandial chylomicron production were significantly lower in VSG relative to Sham animals of both sexes ( p  < 0.01). However, hepatic VLDL production, highest in sham-operated females, was significantly reduced by VSG in females but not males. Taken together, although both males and females lose weight and improve plasma lipids, there are large-scale sex differences in hepatic gene expression and consequently hepatic lipid metabolism after VSG.

Viral hepatitis is responsible for great health, social and economic burden both globally and in the UK. This study aimed to assess the research funding awarded to UK institutions for viral hepatitis research and the relationship of funded research to clinical and public health burden of viral hepatitis. Databases and websites were systematically searched for information on infectious disease research studies funded for the period 1997–2010. Studies specifically related to viral hepatitis research were identified and categorized in terms of funding by pathogen, disease and by a research and development value chain describing the type of science. The overall data set included 6165 studies (total investment £2.6 billion) of which £76.9 million (3.0%) was directed towards viral hepatitis across 323 studies (5.2%). By pathogen, there were four studies specifically investigating hepatitis A (£3.8 million), 69 studies for hepatitis B (21.4%) with total investment of £14.7 million (19.1%) and 236 (73.1%) hepatitis C studies (£62.7 million, 81.5%). There were 4 studies investigating hepatitis G, and none specifying hepatitis D or E. By associated area, viral hepatitis and therapeutics research received £17.0 million, vaccinology £3.1 million and diagnostics £2.9 million. Preclinical research received £50.3 million (65.4%) across 173 studies, whilst implementation and operational research received £19.4 million (25.3%) across 128 studies. The UK is engaged in much hepatology research, but there are areas where the burden is great and may require greater focus, such as hepatitis E, development of a vaccine for hepatitis C, and further research into hepatitis-associated cancers. Private sector data, and funding information from other countries, would also be useful in priority setting. PMID:25146854

The aim of this study was to investigate if neonatal transfusions could underlie chronic hepatitis C in adults for whom the disease transmission route was previously unknown. Questionnaires were sent to 255 patients with chronic hepatitis C born in Sweden in 1960 to 1975. The medical records of 230 of the patients, of whom 98 (43%) had unknown transmission route, were studied regarding the occurrence of neonatal blood transfusions. The clinical, virologic, and histopathologic characteristics of those found to have received transfusions as neonates were also studied. Four of 230 (1.7%; 95% confidence interval, 0.5%-4.4%) patients with hepatitis C had received blood products as neonates. Three of them had reported unknown transmission route. One had cirrhosis, while two had mild histopathologic findings on liver biopsy. Three out of four patients in the transfused group, including the patient with liver cirrhosis, had undergone treatment for hepatitis C, all of them with a sustained viral response. Previously unidentified neonatal blood transfusions explain only a small fraction of chronic hepatitis C cases with unknown transmission route. Individual patients infected early in life can develop progressive liver damage as young adults and may benefit from antiviral treatment. The finding suggests that efforts are needed to actively trace and test adults who have been subjected to neonatal blood product transfusion before 1992. © 2013 American Association of Blood Banks.

AIM To investigate whether hepatitis viral DNA load at 24 wk of treatment predicts response at 96 wk in patients with chronic hepatitis B. METHODS A total of 172 hepatitis B envelope antigen (HBeAg)-positive chronic hepatitis B patients who received initial treatment at 16 tertiary hospitals in Hunan Province, China were enrolled in this study. All patients received conventional doses of lamivudine and adefovir dipivoxil, telbivudine, entecavir dispersible tablets, or entecavir tablets for 96 wk. Patients who used other antiviral drugs or antitumor and immune regulation therapy were excluded. Patients were stratified into three groups according to their viral DNA load at 24 wk: < 10 IU/mL (group 1), 10-103 IU/mL (group 2), and > 103 IU/mL (group 3). Correlations of 24-wk DNA load with HBeAg negative status and HBeAg seroconversion at 96 wk were analyzed. Receiver operating characteristic curve analysis was used to test the predictive value of the HBV DNA load at 24 wk for long-term response. RESULTS The rates of conversion to HBeAg negative status and HBeAg seroconversion rates were 53.7% and 51.9%, respectively, in group 1; 35.21% and 32.39% in group 2; and 6.38% and 6.38% in group 3. The receiver operating characteristic curves for the three subgroups revealed that the lowest DNA load (< 10 IU/mL) was better correlated with response at 96 wk than a higher DNA load (10-103 IU/mL). Nested PCR was used for amplifying and sequencing viral DNA in patients with a viral DNA load > 200 IU/mL at 96 wk; resistance mutations involving different loci were present in 26 patients, and three of these patients had a viral DNA load 10-103 IU/mL at 96 wk. CONCLUSION Hepatitis B viral DNA load at 24 wk of antiviral treatment in patients with chronic hepatitis B is a predictor of the viral load and response rate at 96 wk. PMID:28522916

Advice to rest and take things easy if patients become fatigued during radiotherapy may be detrimental. Aerobic walking improves physical functioning and has been an intervention for chemotherapy-related fatigue. A prospective, randomized, controlled trial was performed to determine whether aerobic exercise would reduce the incidence of fatigue and prevent deterioration in physical functioning during radiotherapy for localized prostate carcinoma. Sixty-six men were randomized before they received radical radiotherapy for localized prostate carcinoma, with 33 men randomized to an exercise group and 33 men randomized to a control group. Outcome measures were fatigue and distance walked in a modified shuttle test before and after radiotherapy. There were no significant between group differences noted with regard to fatigue scores at baseline (P = 0.55) or after 4 weeks of radiotherapy (P = 0.18). Men in the control group had significant increases in fatigue scores from baseline to the end of radiotherapy (P = 0.013), with no significant increases observed in the exercise group (P = 0.203). A nonsignificant reduction (2.4%) in shuttle test distance at the end of radiotherapy was observed in the control group; however, in the exercise group, there was a significant increase (13.2%) in distance walked (P = 0.0003). Men who followed advice to rest and take things easy if they became fatigued demonstrated a slight deterioration in physical functioning and a significant increase in fatigue at the end of radiotherapy. Home-based, moderate-intensity walking produced a significant improvement in physical functioning with no significant increase in fatigue. Improved physical functioning may be necessary to combat radiation fatigue.

Booster doses could play a major role in no responders or low responders to primary hepatitis B (HB) vaccine. Planed time point for hepatitis A vaccination in China provides a good opportunity to carry out HB booster dose by using combined hepatitis A and B vaccine. A randomized, double-blinded clinical trial was conducted to compare the immunogenicity and safety of toddlers 18-24 months of age receiving 3 different vaccination regimens: 2 doses of inactivated hepatitis A vaccine (group 1), 1 dose of inactivated hepatitis A vaccine plus 1 dose of combined hepatitis A and B vaccine (group 2) or 2 doses of combined hepatitis A and B vaccine (group 3). All 3 groups showed 100% seroprotection for antihepatitis A virus antibody after vaccination. Seroprotection rate for anti-HB antibody before vaccination ranged from 79.5% to 92.9% in the 3 groups. After second inoculation, anti-HBs seroprotection increased from 92.9% to 100% in group 2 with postvaccination geometric mean concentration (GMC) of 2258.3 mIU/mL and from 79.5% to 98.9% in group 3 with postvaccination GMC of 2055.3 mIU/mL. The adverse events were not statistically different among groups (P = 0.345). Combined hepatitis A and B vaccine could stimulate high level of both antihepatitis A virus and anti-HBs antibodies and not increase adverse events, providing a new choice for HB booster.

As acute viral hepatitis can be fatal in patients with cirrhosis, vaccination against hepatitis A (HAV) and hepatitis B (HBV) is recommended for non-immune patients. With increasing affluence the incidence of hepatitis A in childhood has decreased leading to a significant proportion of non-immune adults. As part of their routine investigation, hepatitis A IgG antibodies (anti-HAV IgG), hepatitis B surface antigen (HBsAg) and anti-HCV antibodies was checked and immunization status was assessed among consenting newly diagnosed cirrhotic patients presenting to a tertiary referral center. Out of 135 patients, 107 [79.3%; males 91; mean age (SD) at presentation: 55.5 (11.6) years] with complete data were included for analysis. Most patients had either cryptogenic cirrhosis (62.6%) or alcoholic cirrhosis (29.9%); 2 (1.9%) had HBV cirrhosis, none had hepatitis C (HCV) cirrhosis. None of the patients had received vaccination against hepatitis A, while 71 (67.6%) had been vaccinated against HBV. The majority [62 (58%)] were negative for anti-HAV IgG. Most cirrhotic patients in this cohort were not immune to hepatitis A. None had been vaccinated against HAV, while a third of patients had not been vaccinated against HBV. Cirrhotic patients should be routinely investigated for immunity against HAV and HBV, and vaccination offered to those found to be non-immune.

Perflubutane microbubbles, a second-generation ultrasound contrast agent, are phagocytized by Kupffer cells. This characteristic may be useful to differentiate diffuse hepatic diseases in dogs. To determine whether the washout ratio in the hepatic vein (HV) measured by contrast-enhanced ultrasonography (CEUS) can distinguish between inflammatory and noninflammatory hepatic disorders in dogs. Forty-one client-owned dogs with hepatic disorders including 14 with hepatitis, 7 with primary hypoplasia of the portal vein (PHPV), 9 with congenital portosystemic shunt (cPSS), and 11 with other hepatopathy were enrolled. Six dogs without hepatic disease also were evaluated as healthy controls. Dogs with hepatic disorders were prospectively included. Contrast-enhanced ultrasonography of the HV was performed for 2 minutes. Washout ratio was defined as the attenuation rate from peak intensity to the intensity at the end of the CEUS study. Washout ratio in the hepatitis group (median, 18.0%; range, 2.0-37.0%) was significantly lower than that of the PHPV (median, 52.2%; range, 11.5-86.3%), cPSS (median, 60.0%; range, 28.6-77.4%), other hepatopathy (median, 70.5%; range, 26.6-88.4%), and normal (median, 78.0%; range, 60.7-91.7%) groups. The area under the receiver operating characteristic curve for hepatitis was 0.960, with a 95% confidence interval (CI) of 0.853-0.990. Washout ratio ≤37.1% resulted in a sensitivity of 100% (95% CI, 78.5-100%) and specificity of 85.2% (95% CI, 67.5-94.1%) for the prediction of hepatitis. Washout ratio can distinguish hepatitis from the other noninflammatory disorders with high accuracy. This result might reflect impaired Kupffer cell phagocytosis in dogs with hepatitis.

2017-08-01

Hepatic encephalopathy is challenging complication of liver dysfunction. Therapeutic treatment options for hepatic encephalopathy are currently limited and have appreciable risks and benefits associated with their use. Rifaximin is a novel anti microbiological agent with wide spectrum of activity that has shown promise as an alternative option for hepatic encephalopathy. The present study was undertaken to compare the effectiveness of Rifaximin and Lactulose as a combination vs Lactulose alone, to compare the adverse effects and to study the rapidity of therapeutic effects of Rifaximin and Lactulose. It was a prospective observational study. 60 patients suffering from hepatic encephalopathy (HE) were studied. Patients were investigated and treated as per treating physician's decision. At the time of analysis, patients were divided into 2 groups, Rifaximin group who received Rifaximin+Lactulose (R+L) and Lactulose group(L), who received Lactulose only. Parameters such as mental status grade, Asterixis grade, Serum Ammonia grade, Number Connection Test grade (NCT grade), Hepatic Encephalopathy Index (HE index) were evaluated and compared in both groups. Clinical efficacy was determined using HE index improvement. Primary end points were decrease in HE index and reversal of HE grades. Secondary end points were mortality from HE or any other cause, decrease in mental status grade, asterixis grade, serum Ammonia grade, NCT grade. Out of 60 patients, 32 received Rifaximin+Lactulose combination and 28 patients received Lactulose alone. Mean Child-Turcotte-Pugh score (CTP score) was 10.6 in R+L group and 10.32 in L group. There was statistically significant improvement in mental status grade, Asterixis grade, Serum Ammonia grade, NCT grade, Hepatic encephalopathy index in both groups, p value <0.05 but no statistically significant difference between improvement in mental status grade, Asterixis grade, Serum Ammonia grade, NCT grade, HE index between the two groups

To describe the pattern of drug use among men who have sex with men (MSM) living in Spain and its association with sexual risk practices. The European MSM Internet Survey was implemented in 2010 in 38 European countries on websites for MSM and collected data on sociodemographics, sexual behavior, and other sexual health variables. The association between unprotected anal intercourse (UAI) with casual partners and drug consumption was evaluated using multivariate logistic regression models. Among the 13,111 participants, most consumed drugs were cannabis (30.1%), popper (28.4%) and cocaine (18.7%). The risk of UAI with casual partners was 1.5 among those who had used drugs in relation to the other participants. The proportion of MSM who had injected drugs at least once in life was 2.5%, and 1.4% in the last 12 months. The prevalence of UAI with casual partners (53.4%), human immunodeficiency virus (HIV) (23%), hepatitis C (8.2%) and sexually transmitted infections (STI) (15.8%) was higher in MSM injectors related to those who had not used injected drugs (P<.05). The results of this study confirm a high prevalence of drug use in MSM and their relationship to sexual risk behavior. Although the use of injected drugs in MSM is a minority, this group reported a higher level of sexual risk behaviors, self-reported HIV, hepatitis C and other STI.

Men's sex-dominance inhibition: do men automatically refrain from sexually dominant behavior?

PubMed

Kiefer, Amy K; Sanchez, Diana T

2007-12-01

Men receive conflicting messages about their sexual roles in heterosexual relationships. Men are socialized to initiate and direct sexual activities with women; yet societal norms also proscribe the sexual domination and coercion of women. The authors test these competing hypotheses by assessing whether men inhibit the link between sex and dominance. In Studies 1a and b, using a subliminal priming procedure embedded in a lexical decision task, the authors demonstrate that men automatically suppress the concept of dominance following exposure to subliminal sex primes relative to neutral primes. In Studies 2 and 3, the authors show that men who are less likely to perceive sexual assertiveness as necessary, to refrain from dominant sexual behavior, and who do not invest in masculine gender ideals are more likely to inhibit dominant thoughts following sex primes. Implications for theories of automatic cognitive networks and gender-based sexual roles are discussed.

Retrospective accounts suggest that therapeutic doses of paracetamol can produce severe hepatic injury in patients with putative high-risk conditions, including alcoholism and infectious hepatitis. Metabolism of paracetamol to its hepatotoxic metabolite is enhanced in patients who abuse alcohol, who also have compromised liver defences from depressed hepatic glutathione. To determine the effect of paracetamol on serum liver tests of newly abstinent subjects who abuse alcohol, including subjects with hepatitis C infection. A randomized, double-blind, placebo-controlled study. Adult alcohol abusers with a current drinking episode longer than 7 days received either placebo or paracetamol 4 g/day for 5 days. Of 142 subjects enrolled, 74 received paracetamol and 68 received placebo. Mean ALT activity during treatment increased from 48 to 62 IU/L in the paracetamol group and from 47 to 49 IU/L in the placebo group. Maximum ALT was 238 and 249 IU/L in the paracetamol and control groups respectively. The INR remained unchanged and serum bilirubin decreased in both groups. Subgroup analyses for subjects with alcoholic hepatitis, hepatitis C virus antibody and other subgroups showed no statistical difference between groups. Administration of paracetamol 4 g/day appears safe in newly abstinent patients who abuse alcohol.

Studies indicate that roughly half of health care workers are not immunized against hepatitis B and influenza. Findings from a survey of 1,000 registered nurses (RNs) conducted to analyze their beliefs and actions related to immunization recommendations are reported. Only 8% of the responding RNs chose not to receive vaccination against hepatitis B. The primary reasons that nurses declined hepatitis B vaccination were because they were not working in nursing or did not believe they were at risk of exposure. Similarly, 86% of the RNs reported they had ever received a flu shot, and 69% reported of being immunized during 2 of the previous 4 years. Rationale for receiving immunization included belief in its effectiveness, belief that they were at risk of exposure, and that it was provided free of charge. Reasons for declining included concerns about side effects, lack of concern about getting the illness, and doubts about effectiveness. The nurses who responded to the survey appear to value immunizations and generally adhere to immunization recommendations. Further study needs to be conducted on related issues, including follow-up for assessment of long-term protection of hepatitis B immunization and adherence to guidelines for postexposure prophylaxis. Ongoing monitoring and further study of serious complications of hepatitis B immunizations are also needed.

Despite complete suppression of viral DNA with antiviral agents, in some patients with chronic hepatitis B (CHB), serum levels of alanine aminotransferase (ALT) do not normalize. We investigated factors associated with persistent increases in ALT level in patients with CHB given long-term tenofovir disoproxil fumarate. We analyzed data from 471 hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients with CHB participating in 2 phase 3 trials. We identified patients with an increased level of ALT (above the upper limit of normal range) after 5 years (240 weeks) of tenofovir disoproxil fumarate therapy. We analyzed findings from liver biopsy specimens collected from 467 patients (99%) at baseline and 339 patients (72%) at year 5 of treatment; biopsy specimens were evaluated by an independent pathologist. We performed stepwise, forward, multivariate regression analyses of specified baseline characteristics and on-treatment response parameters to identify factors associated with persistent increases in ALT level. Of the 471 patients, 87 (18%) still had an increased ALT level at year 5 of treatment. Factors associated significantly with a persistent increase in ALT level were a steatosis score of 5% or greater (grade 1 or more) at baseline (odds ratio [OR], 2.236; 95% confidence interval [CI], 1.031-4.852; P = .042) and at year 5 (OR, 3.392; 95% CI, 1.560 ≥ 7.375; P = .002), HBeAg seropositivity at baseline (OR, 3.297; 95% CI, 1.653-6.576; P < .001), and age 40 years or older (OR, 2.099; 95% CI, 1.014-4.342; P = .046). Of the 42 HBeAg-positive patients with steatosis at baseline, 21 (50%) had an increased ALT level at year 5 of treatment. Patients with persistent increases in ALT level were more likely to have an increase in steatosis at year 5 than those with a normal ALT level. HBeAg seropositivity and hepatic steatosis contribute to persistent increases in ALT level in patients with CHB receiving suppressive antiviral treatment. Clinical

Previous studies have identified gaps in hepatitis B care. The objectives of this study were to evaluate the delivery of care among a national cohort of US veterans with chronic hepatitis B infection and examine risk factors for adverse clinical outcomes. We conducted a retrospective cohort study using the Veterans Health Administration Corporate Data Warehouse from 1999 to 2013 to evaluate (1) care delivery and (2) clinical outcomes such as hepatocellular carcinoma, hepatic decompensation, and mortality among US veterans with hepatitis B. Incidence rates with 95% confidence intervals were calculated and Cox regression models were used to evaluate clinical outcomes. We identified 21,419 veterans with a positive hepatitis B surface antigen, and 97% of patients had alanine aminotransferase and 44% had hepatitis B virus DNA testing; hepatitis B e antigen and hepatitis B e antibody were tested <50% of the time. Patients receiving specialty care had a higher prevalence of recommended laboratory testing. Patients with elevated alanine aminotransferase in specialty care were more likely to receive antiviral therapy (50% versus 24% for specialty care versus no specialty care, P < 0.001). Among patients with cirrhosis, 69% received one-time liver imaging. The proportion of follow-up time adherent to annual imaging was 0.39 (standard deviation = 0.42), and the proportion was 0.28 (standard deviation = 0.33) for biannual imaging; both proportions were higher in the specialty care group (all P < 0.05). Antiviral therapy (hazard ratio = 0.85, 95% confidence interval 0.76-0.95, P = 0.005) and liver imaging (hazard ratio = 0.84, 95% confidence interval 0.76-0.91, P < 0.001) were independently associated with decreased mortality in adjusted analyses. We observed a low prevalence of recommended laboratory testing, antiviral therapy initiation, and liver imaging among a national cohort of veterans with hepatitis B infection; antiviral therapy and liver imaging were independently

Committee Opinion No. 655 Summary: Hepatitis B, Hepatitis C, and Human Immunodeficiency Virus Infections in Obstetrician-Gynecologists.

PubMed

2016-02-01

To prevent transmission of bloodborne pathogens, it is important that health care providers adhere to standard precautions, follow fundamental infection-control principles, and use appropriate procedural techniques. All obstetrician-gynecologists who provide clinical care should receive the hepatitis B virus vaccine series. The Society for Healthcare Epidemiology of America has established guidelines for the management of health care providers who are infected with hepatitis B virus, hepatitis C virus, or human immunodeficiency virus (HIV). The guidelines categorize representative obstetric and gynecologic procedures according to level of risk of bloodborne pathogen transmission and include recommendations for health care provider clinical activities, based on these categories and viral burden. It is important to note that when no restrictions are recommended, careful supervision should be carried out as highlighted. These recommendations provide a framework within which to consider such cases; however, each case should be independently considered in context by the expert review panel.

Abstract Rationale: Hepatitis A viral infection is a well-known cause of subclinical or acute self-limited hepatitis. Few cases of hepatitis A virus (HAV)–associated acute liver failure (ALF) have been reported in low HAV endemic countries annually. Patients concerns: To investigate the possible factors that affected the severity of HAV infection, a family cluster infected with the HAV subgenotype IB strain, which is not common in Japan, was described. Diagnoses: This family consisted of five members who all were infected with HAV. Interventions: Four of the five patients hospitalized except for an asymptomatic patient. Outcomes: Two of the five patients, men in their 50s and 60s, developed ALF, and one patient died. Various host factors, including sex (male), age, and a high bilirubin level, may affect the outcomes. Based on viral factors, HAV RNA was higher in the fatal case compared with others, and it decreased within a short period of time. The similarity of the nucleotide sequences was 99.9% among the HAV isolates based on an entire genomic sequence. Deletions and/or insertions on the HAV protein-coding sequences that caused a frameshift were found in surviving cases but not in the fatal case. Lessons: The rapid clearance of increased HAV and the absence of defective HAV might be closely associated with the onset of liver failure. PMID:28858094

To determine the baseline hepatitis B surface antigen (HBsAg) levels during the different phases of chronic hepatitis B (CHB) patients in China. Six hundred and twenty-three hepatitis B virus or un-infected patients not receiving antiviral therapy were analyzed in a cross-sectional study. The CHB patients were classified into five phases: immune-tolerant (IT, n = 108), immune-clearance (IC, n = 161), hepatitis B e antigen negative hepatitis (ENH, n = 149), low-replicative (LR, n = 135), and liver cirrhosis (LC, n = 70). HBsAg was quantified (Abbott ARCHITECT assay) and correlated with hepatitis B virus (HBV) DNA, and serum alanine aminotransferase/aspartate aminotransferase (ALT/AST) in each phase of CHB was also determined. Median HBsAg titers were different in each phase of CHB (P < 0.001): IT (4.85 log10 IU/mL), IC (4.36 log10 IU/mL), ENH (2.95 log10 IU/mL), LR (3.18 log10 IU/mL) and LC (2.69 log10 IU/mL). HBsAg titers were highest in the IT phase and lowest in the LC phase. Serum HBsAg titers showed a strong correlation with HBV viral load in the IC phase (r = 0.683, P < 0.001). No correlation between serum HBsAg level and ALT/AST was observed. The mean baseline HBsAg levels differ significantly during the five phases of CHB, providing evidence on the natural history of HBV infection. HBsAg quantification may predict the effects of immune-modulator or oral nucleos(t)ide analogue therapy.

AIM To examine the clinical features and risk factors for adverse outcomes in chronic hepatitis B (CHB) superimposed with hepatitis E virus (HEV). METHODS This retrospective cohort study included 228 patients with acute HEV infection (showing clinical acute hepatitis symptomology and positivity for anti-HEV immunoglobulin M) with underlying CHB (confirmed by positivity for hepatitis B surface antigen and/or hepatitis B virus (HBV) DNA over 6 mo) who had been admitted to the Shanghai Public Health Clinical Center, which represents the regional tertiary hospital for infectious diseases in Shanghai city, China. Data for adverse outcomes were collected, and included severe liver diseases (defined as liver failure and/or acute liver decompensation) and liver-related mortality. Logistic regression modeling was performed to determine the risk factors for adverse outcomes. RESULTS The symptoms caused by superimposed acute hepatitis E (AHE) were much more severe in cirrhotic patients (n = 94) than in non-cirrhotic patients (n = 134), as evidenced by significantly higher liver complications (77.7% vs 28.4%, P < 0.001) and mortality rate (21.3% vs 7.5%, P = 0.002). Most of the cirrhotic patients (n = 85, 90.4%) had no prior decompensation. Among the non-cirrhotic patients, superimposed AHE caused progressively more severe diseases that corresponded with the CHB disease stages, from immune tolerant to immune reactivation phases. Few risk factors were identified in the cirrhotic patients, but risk factors for non-cirrhotic patients were found to be intermediate HBV DNA levels (OR: 5.1, P = 0.012), alcohol consumption (OR: 6.4, P = 0.020), and underlying diabetes (OR: 7.5, P = 0.003) and kidney diseases (OR: 12.7, P = 0.005). Only 28.7% of the cirrhotic patients and 9.0% of the non-cirrhotic patients had received anti-HBV therapy previously and, in all cases, the efficacy had been suboptimal. CONCLUSION CHB-related cirrhosis and intermediate HBV DNA level were associated with

Acute hepatitis A and E are recognized triggers of hepatic decompensation in patients with cirrhosis, particularly from the Indian subcontinent. However, the resulting acute-on-chronic liver failure (ACLF) has not been well characterized and no large studies are available. Our study aimed to evaluate the clinical profile and predictors of 3-month mortality in patients with this distinctive form of liver failure. ACLF was diagnosed in patients with acute hepatitis A or E [abrupt rise in serum bilirubin and/or alanine aminotransferase with positive immunoglobulin M anti-hepatitis A virus (HAV)/anti-hepatitis E virus (HEV)] presenting with clinical evidence of liver failure (significant ascites and/or hepatic encephalopathy) and clinical, biochemical, endoscopic (oesophageal varices at least grade II in size), ultrasonographical (presence of nodular irregular liver with porto-systemic collaterals) or histological evidence of cirrhosis. Clinical and laboratory profile were evaluated, predictors of 3-month mortality were determined using univariate and multivariate logistic regression and a prognostic model was constructed. Receiver-operating curves were plotted to measure performance of the present prognostic model, model for end-stage liver disease (MELD) score and Child-Turcotte-Pugh (CTP) score. ACLF occurred in 121 (3.75%) of 3220 patients (mean age 36.3+/-18.0 years; M:F 85:36) with liver cirrhosis admitted from January 2000 to June 2006. It was due to HEV in 80 (61.1%), HAV in 33 (27.2%) and both in 8 (6.1%). The underlying liver cirrhosis was due to HBV (37), alcohol (17), Wilson's disease (8), HCV (5), autoimmune (6), Budd-Chiari syndrome (2), haemochromatosis (2) and was cryptogenic in the rest (42). Common presentations were jaundice (100%), ascites (78%) and hepatic encephalopathy (55%). Mean (SD) CTP score was 11.4+/-1.6 and mean MELD score was 28.6+/-9.06. Three-month mortality was 54 (44.6%). Complications seen were sepsis in 42 (31.8%), renal failure in

Background Hepatitis B (HBV), hepatitis C (HCV) and other sexually transmitted infections (STIs) have been associated with HIV transmission risk and disease progression among gay men and other men who have sex with men (MSM), but the frequency and distribution of STIs in this community in Canada has not been extensively studied. Methods We recruited MSM living with and without HIV from a large primary care clinic in Toronto. Participants completed a detailed socio-behavioural questionnaire using ACASI and provided blood for syphilis, HIV, HBV and HCV, herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), and human cytomegalovirus (CMV) serology, urine for chlamydia and gonorrhea, and a self-collected anal swab for human papillomavirus (HPV) molecular diagnostics. Prevalences were expressed as a proportion and compared using chi-square. Results 442 MSM were recruited, 294 living with HIV and 148 without. Active syphilis (11.0% vs. 3.4%), ever HBV (49.4% vs. 19.1%), HCV (10.4% vs. 3.4%), HSV-2 (55.9% vs. 38.2%), CMV (98.3% vs. 80.3%) and high-risk (HR) anal HPV (67.6% vs. 51.7%) infections were significantly more common in men living with HIV. Chlamydia and gonorrhea were infrequent in both groups. Regardless of HIV infection status, age and number of lifetime male sexual partners were associated with HBV infection and lifetime injection drug use with HCV infection. Conclusions Syphilis and viral infections, including HBV, HCV, HSV-2, CMV, and HR-HPV, were common in this clinic-based population of MSM in Toronto and more frequent among MSM living with HIV. This argues for the implementation of routine screening, vaccine-based prevention, and education programs in this high-risk population. PMID:27391265

Few population-based studies have described characteristics and management of patients with chronic hepatitis B (CHB) in the USA. We retrospectively studied adults with CHB in the Northern California Kaiser Permanente Medical Care Program (KPNC) from July 2009 to December 2010 (n = 12,016). Laboratory tests, treatment patterns, and hepatocellular carcinoma (HCC) surveillance were ascertained during a "recent" 18-month study window (July 2009-December 2010), or as "ever" based on records dating to 1995. The mean age was 49 years; 51 % were men, 83 % Asian, and 87 % KPNC members >5 years. Overall, 51 % had ≥ 1 liver-related visit, 14 % with gastroenterology or infectious disease specialists, and 37 % with primary care providers (PCP) only. Less than 40 % of patients had both hepatitis B virus (HBV) DNA and ALT testing conducted recently, while 56 % of eligible patients had received HCC surveillance. Recent laboratory testing and HCC surveillance were more frequent in patients seen by a specialist versus PCP only (90 vs. 47 % and 92 vs. 73 %, respectively, p values <0.001). During the study period, 1,649 (14 %) received HBV treatment, while 5 % of untreated patients had evidence of treatment eligibility. Among 599 patients newly initiated on HBV therapy, 76 % had guideline-based indications for treatment. Most patients initiated on HBV treatment met eligibility, and very few patients with evidence of needing treatment were left untreated. However, monitoring of ALT and HBV DNA levels, as well as HCC surveillance, were not frequent, underestimating the proportion of patients that warranted HBV therapy. Viral monitoring and cancer surveillance are therefore important targets for improving the scope of CHB care in the community setting.

The objective of this study was to evaluate the health-related quality of life in children and adolescents with autoimmune hepatitis. A cross-sectional assessment with the Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0) was completed for 80 patients with autoimmune hepatitis and 45 healthy controls. Demographic data, prednisone dose, disease remission state, disease severity, and abdominal pain were also evaluated. Based on the child self-reports, physical, emotional, school, and total scores were significantly lower in autoimmune hepatitis patients when compared with controls (p<0.05). Based on the parental reports, only the physical and total scores were significantly lower in autoimmune hepatitis patients versus controls (p<0.05). Further analysis in autoimmune hepatitis patients with abdominal pain in the last month revealed significantly lower physical, social, and total median scores (p<0.05). No differences were observed based on disease remission state or disease severity (p>0.05). Autoimmune hepatitis patients who received a prednisone dose below 0.16mg/kg/day at the time of the interview showed significantly higher physical scores than those who received a dose similar to or above 0.16mg/kg/day (87.5 [50-100] vs. 75 [15.63-100], p=0.006). Reduced scores in the physical, emotional, and school domains were observed in pediatric autoimmune hepatitis patients compared to control patients. Abdominal pain and corticosteroid dose negatively influenced the health-related quality of life in children and adolescents with autoimmune hepatitis.

Since mid-2016, hepatitis A virus (HAV) outbreaks, involving predominantly men who have sex with men (MSM), have affected countries in Europe and overseas. In France, HAV screening of blood donations in 2017 revealed a HAV-RNA prevalence ca fivefold higher than during 2015-16 (4.42/106 vs 0.86/106; p = 0.0005). In 2017, despite a higher male-to-female ratio (5.5 vs 0.7) and the identification of MSM-associated outbreak strains, only one of 11 infected male donors self-reported being a MSM.

To examine the long-term impact of health counselling among middle-aged men at high risk of CVD. An observational study with a 5-year follow-up. All men aged 40 years in Helsinki have been invited to a visit to evaluate CVD risk from 2006 onwards. A modified version of the North Karelia project risk tool (CVD risk score) served to assess the risk. High-risk men received lifestyle counselling based on their individual risk profile in 2006 and were invited to a follow-up visit in 2011. Of the 389 originally high-risk men, 159 participated in the follow-up visits in 2011. Based on their follow-up in relation the further risk communication, we divided the participants into three groups: primary health care, occupational health care and no control visits. Lifestyle and CVD risk score change. All groups showed improvements in lifestyles. The CVD risk score decreased the most in the group that continued the risk communication visits in their primary health care centre (6.1 to 4.8 [95% CI -1.6 to -0.6]) compared to those who continued risk communication visits in their occupational health care (6.0 to 5.4 [95% CI -1.3 to 0.3]), and to those with no risk communication visits (6.0 to 5.9 [95% CI -0.5 to 0.4]). These findings indicate that individualized lifestyle counselling improves health behaviour and reduces total CVD risk among middle-aged men at high risk of CVD. Sustained improvement in risk factor status requires ongoing risk communication with health care providers. KEY POINTS Studies of short duration have shown that lifestyle changes reduce the risk of cardiovascular disease among high-risk individuals. Sustaining these lifestyle changes and maintaining the lower disease risk attained can prove challenging. Cardiovascular disease (CVD) risk assessment and individualized health counselling for high-risk men, when implemented in primary health care, have the potential to initiate lifestyle changes that support risk reduction.

While three types of hepatitis A vaccines are available in China, little data are available to compare them in terms of early antibody response. We conducted a trial to compare antibody response at 7, 14 and 28 days. We randomized primary school children in Gansu and Jilin provinces into four groups to receive either (1) Chinese live attenuated hepatitis A vaccine (H2 strain), (2) domestic inactivated hepatitis A vaccine (Healive(®)), (3) imported inactivated hepatitis A vaccine (Havrix(®)) or (4) hepatitis B vaccine (Control group). We compared groups at 7, 14 and 28 days in terms of proportion of sero-conversions (≥10 mUI/ml), and Geometric Mean Concentration (GMC) of antibodies measured with a Microparticle Enzyme Immunoassay (MEIA). We compared rates of self-reported adverse events following immunization (AEFI) in the first three days. 204 children received the H2 vaccine, 208 received Healive(®), 214 received Havrix(®), and 215 received hepatitis B vaccine (no differences across groups in terms of age, sex, weight and height). At seven days, sero-conversion proportions were 25%, 35%, 27% and 2% (p<0.0001) with GMC of 6 mIU/ml, 8 mIU/ml, 6 mIU/ml and 3 mIU/ml, respectively for the four groups. At 28 days, sero-conversion proportions were 98%, 100%, 93% and 3% (p<0.0001) with GMC of 47 mIU/ml, 71 mIU/ml, 67 mIU/ml and 3 mIU/ml, respectively. AEFI were benign and did not differ across groups (p=0.94). While our study was not able to identify differences between Havrix(®), Healive(®) and H2 vaccine in terms of sero-conversion proportion and GMC between seven and 28 days, further studies should evaluate non-inferiority or equivalence of the Chinese vaccines, particularly with respect to the GMC concentration for the H2 vaccine since it could affect long-term protection.

The liver normally produces a large amount of lymph. It is estimated that between 25% and 50% of the lymph received by the thoracic duct comes from the liver. In normal conditions, hepatic lymphatics are not depicted on cross-sectional imaging. They are divided in lymphatics of deep system (lymphatics following the hepatic veins and the portal tract) and those of superficial system (convex surface and inferior surface). A variety of diseases may affect hepatic lymphatics and in general they manifest as lymphedema, lymphatic mass, or cystic lesions. Abnormal distended lymphatics are especially seen in periportal spaces as linear hypoattenuations on CT or strong linear hyperintensities on heavily T2-weighted MR imaging. Lymphatic tumor spread as in lymphoma and lymphangitic carcinomatosis manifests as periportal masses and regional lymph node enlargement. Lymphatic disruption after trauma or surgery is depicted as perihepatic fluid collections of lymph (lymphocele). Lymphatic malformation such as lymphangioma is seen on imaging as cystic spaces of variable size.

The purpose of this study was to evaluate the prevalence, patterns and predictors (individual, social, cultural, and environmental) of illicit drug use and binge drinking in a cohort of Latino migrant men (LMM) in a new receiving community. A cohort of LMM in New Orleans (n=125) was assembled in 2007 using respondent driven sampling and interviewed quarterly for 18 months regarding past month substance use and other potential covariates. Baseline frequencies were weighted using RDSAT and longitudinal analyses included generalized estimating equations (GEE) and the Cochran-Armitage test for trends. At baseline, substance use behaviors were: drug use 15.0% (range 7.3-25.0%) and binge drinking 58.3% (range 43.6-74.6%). All three of these behaviors decreased over follow-up (P<0.01). Baseline alcohol dependence and drug problem were 11.8% (range 5.6-24.3%) and 0.08% (range 0.00-2.7%) and both remained the same over time. Baseline rate of chlamydia was 9% (range 0.00-22.4%); all men tested negative for gonorrhea, HIV, and syphilis. For both binge drinking and drug use, having sex with a female sex worker was associated with increased risk, whereas belonging to a club or organization was associated with less risk. Additional factors associated with increased drug use were: having a friend in New Orleans upon arrival, symptoms of depression, and working in construction. An additional factor associated with less binge drinking was having family in New Orleans upon arrival. Among LMM, substance use is influenced by social and environmental factors. Interventions increase community connectedness may help decrease usage. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

This study clarified the characteristics of travelers who received hepatitis B vaccinations. Subjects were 233 Japanese travelers who visited our clinic prior to travel. We summarized the characteristics of the clients and performed two comparative studies: first, we compared a hepatitis B-vaccinated group with an unvaccinated group; second, we compared a group that had completed the hepatitis B vaccine series with a group that did not complete the series. The hepatitis B vaccine was administered to 152 clients. Factors positively associated with the hepatitis B vaccination (after adjusting for age and sex) included the following: travel for business or travel as an accompanying family member; travel to Asia; travel for a duration of a month or more; and, inclusion of the vaccine in a company or organization's payment plan. Meanwhile, factors negatively associated with the vaccination were travel for leisure or education, and travel to North America or Africa. Among 89 record-confirmed cases, only 53 completed 3 doses. The completion rate was negatively associated with the scheduled duration of travel if it was from a month to less than a year (after adjusting for age and sex). The present study provides a basis for promoting vaccination compliance more vigorously among Japanese adults.

To determine the prevalence of the vaccine-preventable diseases caused by varicella, measles, rubella, and hepatitis A and B viruses in a multinational healthcare workforce. Prospective cohort study. A 750-bed tertiary care center located in Riyadh, Saudi Arabia. In compliance with hospital policy, newly recruited healthcare workers (HCWs) were enrolled in the study from September 2001 to March 2005. Serum samples were collected from all HCWs during the initial hiring process and tested for IgG antibodies against each of the 5 viral agents. Nonimmune HCWs were subsequently vaccinated at the earliest opportunity. A total of 4,006 newly hired (international and local) employees were included in the study. All underwent serologic testing for IgG antibodies against varicella, measles, rubella, hepatitis A, and hepatitis B viruses. Of the total, 63% were female and 37% were male. Middle Eastern employees comprised 47% of the total, followed by employees from the Far East (35%), the West (10%), and Africa (8%). Forty-two percent were nurses, 27% were in administration, 18% were medical technicians, and 13% were physicians. Among the 4,006 newly hired HCWs, 14% had negative IgG antibody test results for varicella virus, 13% for measles virus, 10% for rubella virus, 33% for hepatitis A virus, and 43% for hepatitis B virus. More women than men were susceptible to hepatitis A (40% vs. 24%; P<.001), whereas more men were susceptible to hepatitis B (55% vs. 35%; P<.001). Varicella susceptibility was more common among HCWs from the Far East (19%), whereas susceptibility to measles, rubella, hepatitis A, and hepatitis B was highest among HCWs from the Middle East. Both relative youth and male sex were associated with lack of antibodies against hepatitis B virus and rubella virus. In contrast, female sex and younger age were associated with lack of antibodies against hepatitis A virus (P<.001). Seroprevalence surveys of vaccine-preventable diseases among HCWs, although labor

In 2002, the US Department of Defense (DoD) mandated hepatitis B immunization for military recruits. A DoD study reported that screening for immunity with selective immunization would be cost-effective at a prevalence of immunity of >12%. The prevalence of hepatitis B immunity in the military recruit population was unknown. We studied a random sample of Army, Navy, and Marine Corps new recruits (2400 men and women from all 50 states, Puerto Rico, and US territories). Banked serum samples collected in 2001 were tested for antibody to hepatitis B surface antigen (anti-HBs) by AUSAB enzyme-linked immunoassay (EIA). Results were evaluated by military service branch, age, sex, race, level of education, geographic region of origin, and presence of state immunization laws. The overall prevalence of anti-HBs seropositivity, adjusted to the age distribution of the recruit population in 2001, was 31.5% (95% confidence interval [CI], 29.6%-33.4%). The prevalence of anti-HBs seropositivity, directly adjusted to the 18-35-year-old US population in 2000, was 23.0% (95% CI, 20.7%-25.3%). Anti-HBs seropositivity prevalence was highest among the young, decreased with increasing age, and was higher in women, recruits from the Northeast and West, and recruits from states with laws mandating hepatitis B immunization before entry into elementary and middle school. Screening new recruits for evidence of immunity before hepatitis B immunization is indicated. The prevalence of immunity increased with successive birth cohorts and may reflect the success of childhood immunization programs.

Hepatitis A viral infection is a well-known cause of subclinical or acute self-limited hepatitis. Few cases of hepatitis A virus (HAV)-associated acute liver failure (ALF) have been reported in low HAV endemic countries annually. To investigate the possible factors that affected the severity of HAV infection, a family cluster infected with the HAV subgenotype IB strain, which is not common in Japan, was described. This family consisted of five members who all were infected with HAV. Four of the five patients hospitalized except for an asymptomatic patient. Two of the five patients, men in their 50s and 60s, developed ALF, and one patient died. Various host factors, including sex (male), age, and a high bilirubin level, may affect the outcomes. Based on viral factors, HAV RNA was higher in the fatal case compared with others, and it decreased within a short period of time. The similarity of the nucleotide sequences was 99.9% among the HAV isolates based on an entire genomic sequence. Deletions and/or insertions on the HAV protein-coding sequences that caused a frameshift were found in surviving cases but not in the fatal case. The rapid clearance of increased HAV and the absence of defective HAV might be closely associated with the onset of liver failure.

With the effective control of hepatitis B infection among children, the adults especial the young ones become the main population for new hepatitis B virus infection. Now the adults receive hepatitis B vaccination voluntarily and at their own expense in China and the coverage is low. The high immunogenicity of hepatitis B vaccine has been proven among healthy adults. Although the safety of hepatitis B vaccination has been documented among high-risk population such as HIV-infected people, injecting drug users and patients with chronic hepatitis disease, their antibody seroconversion rate after hepatitis B vaccination is lower than the healthy adults. Hepatitis B vaccination is recommended to population at high risk officially in many countries and some effects have been achieved. It is urgent to improve the strategy of hepatitis B vaccination among adults to fasten the control of hepatitis B in China, along with the researches about the long-term efficacy of hepatitis B vaccine among adults, the immunogenicity of hepatitis B vaccination among high-risk adults and the economical evaluation about different adult immunization strategy of hepatitis B.

The aim of the study was to analyse associations between chemsex and new HIV and sexually transmitted infection (STI) diagnoses among gay, bisexual and other men who have sex with men (GBMSM) accessing sexual health clinics. A retrospective case note review was carried out for all GBMSM attending two London sexual health clinics between 1 June 2014 and 31 July 2015. Chemsex status was documented for 1734 of 1840 patients. Overall, 27.1% (n = 463) disclosed current recreational drug use, of whom 286 (16.5%) disclosed chemsex participation and 74 of 409 (18.1%) injected drugs. GBMSM who were already HIV positive were more likely to disclose chemsex participation [adjusted odds ratio (AOR) 2.55; 95% confidence interval (CI) 1.89-3.44; P < 0.001]. Those disclosing chemsex participation had higher odds of being newly diagnosed with HIV infection (AOR 5.06; 95% CI 2.56-10.02; P < 0.001), acute bacterial STIs (AOR 3.94; 95% CI 3.00-5.17; P < 0.001), rectal STIs (AOR 4.45; 95% CI 3.37-6.06; P < 0.001) and hepatitis C (AOR 9.16; 95% CI 2.31-36.27; P = 0.002). HIV-negative chemsex participants were also more likely to have accessed post-exposure prophylaxis for HIV in the study period and to report sex with a discordant HIV- or hepatitis C virus-infected partner (P < 0.001). Chemsex disclosure in sexual health settings is associated with higher rates of STI diagnoses, including HIV infection and hepatitis C. GBMSM attending sexual health services should therefore be assessed for chemsex participation and disclosure should prompt health promotion, harm minimization and wellbeing interventions. © 2018 British HIV Association.

Can Hepatitis C Virus (HCV) Direct-Acting Antiviral Treatment as Prevention Reverse the HCV Epidemic Among Men Who Have Sex With Men in the United Kingdom? Epidemiological and Modeling Insights.

We report on the hepatitis C virus (HCV) epidemic among human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) in the United Kingdom and model its trajectory with or without scaled-up HCV direct-acting antivirals (DAAs). A dynamic HCV transmission model among HIV-diagnosed MSM in the United Kingdom was calibrated to HCV prevalence (antibody [Ab] or RNA positive), incidence, and treatment from 2004 to 2011 among HIV-diagnosed MSM in the UK Collaborative HIV Cohort (UK CHIC). The epidemic was projected with current or scaled-up HCV treatment, with or without a 20% behavioral risk reduction. HCV prevalence among HIV-positive MSM in UK CHIC increased from 7.3% in 2004 to 9.9% in 2011, whereas primary incidence was flat (1.02-1.38 per 100 person-years). Over the next decade, modeling suggests 94% of infections are attributable to high-risk individuals, comprising 7% of the population. Without treatment, HCV chronic prevalence could have been 38% higher in 2015 (11.9% vs 8.6%). With current treatment and sustained virological response rates (status quo), chronic prevalence is likely to increase to 11% by 2025, but stabilize with DAA introduction in 2015. With DAA scale-up to 80% within 1 year of diagnosis (regardless of disease stage), and 20% per year thereafter, chronic prevalence could decline by 71% (to 3.2%) compared to status quo in 2025. With additional behavioral interventions, chronic prevalence could decline further to <2.5% by 2025. Epidemiological data and modeling suggest a continuing HCV epidemic among HIV-diagnosed MSM in the United Kingdom driven by high-risk individuals, despite high treatment rates. Substantial reductions in HCV transmission could be achieved through scale-up of DAAs and moderately effective behavioral interventions. © The Author 2016.

"Macho men" and preventive health care: implications for older men in different social classes.

PubMed

Springer, Kristen W; Mouzon, Dawne M

2011-06-01

The gender paradox in mortality--where men die earlier than women despite having more socioeconomic resources--may be partly explained by men's lower levels of preventive health care. Stereotypical notions of masculinity reduce preventive health care; however, the relationship between masculinity, socioeconomic status (SES), and preventive health care is unknown. Using the Wisconsin Longitudinal Study, the authors conduct a population-based assessment of masculinity beliefs and preventive health care, including whether these relationships vary by SES. The results show that men with strong masculinity beliefs are half as likely as men with more moderate masculinity beliefs to receive preventive care. Furthermore, in contrast to the well-established SES gradient in health, men with strong masculinity beliefs do not benefit from higher education and their probability of obtaining preventive health care decreases as their occupational status, wealth, and/or income increases. Masculinity may be a partial explanation for the paradox of men's lower life expectancy, despite their higher SES.

A high-fat, high-calorie diet is associated with obesity and type 2 diabetes. However, the relative contribution of metabolic defects to the development of hyperglycaemia and type 2 diabetes is controversial. Accumulation of excess fat in muscle and adipose tissue in insulin resistance and type 2 diabetes may be linked with defective mitochondrial oxidative phosphorylation. The aim of the current study was to investigate acute effects of short-term fat overfeeding on glucose and insulin metabolism in young men. We studied the effects of 5 days' high-fat (60% energy) overfeeding (+50%) versus a control diet on hepatic and peripheral insulin action by a hyperinsulinaemic euglycaemic clamp, muscle mitochondrial function by (31)P magnetic resonance spectroscopy, and gene expression by qrt-PCR and microarray in 26 young men. Hepatic glucose production and fasting glucose levels increased significantly in response to overfeeding. However, peripheral insulin action, muscle mitochondrial function, and general and specific oxidative phosphorylation gene expression were unaffected by high-fat feeding. Insulin secretion increased appropriately to compensate for hepatic, and not for peripheral, insulin resistance. High-fat feeding increased fasting levels of plasma adiponectin, leptin and gastric inhibitory peptide (GIP). High-fat overfeeding increases fasting glucose levels due to increased hepatic glucose production. The increased insulin secretion may compensate for hepatic insulin resistance possibly mediated by elevated GIP secretion. Increased insulin secretion precedes the development of peripheral insulin resistance, mitochondrial dysfunction and obesity in response to overfeeding, suggesting a role for insulin per se as well GIP, in the development of peripheral insulin resistance and obesity.

Hepatitis B is the most common chronic viral infection in humans and the most common cause of death among viral hepatitis. As 70% to 80% of chronic hepatitis cases are caused by HBV in Iran, this virus alone is considered the most important cause of liver diseases and the major cause of mortality arising from viral hepatitis cases in Iran. We planned this study to determine the prevalence of hepatitis B in the general population of Qom, central Iran. The present study is a cross-sectional study. A total of 3690 samples were collected from 7 rural clusters and 116 urban clusters. Ten teams, each consisting of 2 trained members, were assigned to conduct the sampling and fill the questionnaires. The data were analyzed using SPSS. The prevalence rate of hepatitis B infection in Qom Province was 1.3%. The mean age of the patients with hepatitis B was 44.17 years. The prevalence of hepatitis B was 1.6% in men and 1.1% in women. Moreover, the prevalence of hepatitis B correlated positively with age, tattooing, and literacy level. The prevalence rate of hepatitis B in Qom is 1.3%. It is possible to prevent the disease by increasing public awareness. Further investigation on clinical presentations and a determination of the genotype of the virus are suggested.

To (a) determine whether the information provided to men with prostate cancer and their partners in the immediate postdiagnostic phase met their needs; and (b) examine patient and partner satisfaction with the information received. Pre-intervention survey data from a pilot randomized controlled trial of a self-directed coping skills intervention involving 42 patients with prostate cancer, and their partners were collected to examine their psychosocial concerns/needs. The main concerns for patients and partners were psychosocial in nature such as managing emotions, concern about the future, and losing control. Overall, patients and partners received most information about tests and treatment options. Partners reported receiving significantly less information about support services ( P = 0.03) and self-care strategies ( P = 0.03) compared to patients. Partners also reported being significantly less satisfied with the information they received ( P = 0.007). Whereas medical information is routinely given, patients and partners may benefit from greater information about psychosocial issues arising from cancer. Despite increased recognition of partner's information needs these still remain unmet.

Children with nephrotic syndrome have been shown to have lower seroconversion to various vaccines due to immune dysregulation, prolonged immunosuppressive treatment and recurrent prolonged proteinuria.The primary aim of this study was to determine hepatitis B surface antibody (anti-HBs) titers in children with nephrotic syndrome who had been previously vaccinated against hepatitis B. The secondary aim was to study the association of anti-HBs titers with type of disease, schedule and dose of vaccination, and type of immunosuppressive therapy. This cross-sectional study was conducted in the Department of Pediatrics in a tertiary care hospital between January 2011 and January 2012). All children (aged 1-18 years) with nephrotic syndrome who tested negative for hepatitis B surface antigen and who had previously been vaccinated against hepatitis B, with the last dose being at least 1 month prior to being included in the study. A form consisting of history and clinical details was filled in, and the schedule and dose of vaccination(s) received was noted. A blood sample was taken from all patients for biochemical assessment and determination of anti-HBs titer. The patient cohort comprised 75 children (51 males; 24 females) of whom 42 (56%) had steroid-resistant nephrotic syndrome (SRNS) and 33 (44%) had steroid-sensitive nephrotic syndrome (SSNS). Most patients enrolled in the study (96%) were in remission at the time of the biochemical and serological assessment. Twenty-one (28%) patients had received only steroids, while 72 % also received other immunosuppressants. Forty-six (61.3%) patients had received a double dose of vaccine. Of the 75 children enrolled, 36 (48%) and 39 (52%) had an anti-HBs titer of ≥10 mIU/mL (seroprotected) and <10 mIU/mL (unprotected), respectively. The mean titer among all patients was 143.58 mIU/mL. The seroprotection rates were 63.6% in SSNS patients and 35.7% in SRNS subjects (P = 0.016). Based on our results, we conclude that children

HIV-1 and Hepatitis B and C viruses coinfection is common in Sub-Saharan Africa due to similar routes of transmission and high levels of poverty. Most studies on HIV-1 and Hepatitis B and C viruses have occurred in hospital settings and blood transfusion units. Data on Hepatitis B and C viruses and HIV-1 coinfection in informal urban settlements in Kenya are scanty, yet they could partly explain the disproportionately high morbidity and mortality associated with HIV-1 infections in these slums. The objective of this study was to determine the prevalence of HIV and Hepatitis B and C dual infection in urban slums in Nairobi. Blood samples were collected from residents of Viwandani and Korogocho between 2006 and 2007. A structured questionnaire was used to obtain socio-demographic data from participants. Samples were screened for Hepatitis B surface antigen (HBsAg), anti-HCV and anti-HIV-1. Statistical analysis was done using STATA. Samples were successfully collected from 418 (32%) men and 890 (68%) females. The HIV-1, HBV and HCV prevalence was 20.4%, 13.3% and 0.76% respectively at the time of the study. Of the 268 (20.4%) HIV-1 positive participants, 56 (4.26%) had HBV while 6 (0.46%) had HCV. Of the 1041 HIV-1 negative participants, 117 (8.9%) had HBV while 4 (0.31%) had HCV. Only two people (0.15%) were co-infected with all the three viruses together. The odds of getting hepatitis infection were higher in HIV-1 participants (for HBV OR 2.08,p<0.005 and for HCV OR 5.93, p<0.005). HIV prevalence rates were similar in both informal settlements. HIV infection was highest in age group 35-39 years and among the divorced/separated or widowed. Prevalence of all viruses was highest in those who did not have any formal education. The HIV prevalence in these informal settlements suggests a higher rate than what is observed nationally. The prevalence rates of HBV are significantly higher in the HIV-1 positive and negative populations. HCV as well as triple HIV-1, HBV and

We analyzed the 5-year post-treatment response to peginterferon α-2a (PEG IFN-α-2a) in hepatitis B e-antigen (HBeAg) positive and negative chronic hepatitis B patients. One hundred and thirty-seven chronic hepatitis B (CHB) patients receiving 90 μg or 180 μg of PEG IFN-α-2a for 24 or 48 weeks in phase II or III studies were enrolled in the study, including 100 HBeAg positive patients and 37 HBeAg negative patients; 121 patients (88.4%) had genotype C. Of the 137 patients, 94 received additional antiviral therapy because of viral reactivation and 43 did not receive any additional antiviral treatment during follow up. Five years upon PEG IFN-α-2a treatment, 32 patients (23.4%) who did not receive any additional antiviral agent after PEG IFN-α-2a therapy achieved a good response (normal serum alanine aminotransferase, low-level hepatitis B virus [HBV] DNA, and HBeAg negativity). Female sex and low HBV DNA levels by the end of treatment were independently associated with favorable 5-year post-treatment responses. Forty-eight-week administration of PEG IFN-α-2a showed a better response (26.4%) than 24-week administration (18.0%). Six patients (4.3%), four males and two females, cleared hepatitis B surface antigen (HBsAg) during the 5-year follow-up period. The 48-week administration of PEG IFN-α-2a achieved better biochemical and virological responses than the 24-week administration, particularly in younger females. The 5-year post-treatment response rate was 23.4%; however, more than two-thirds of the patients received additional antiviral therapy because of viral reactivation after PEG IFN-α-2a treatment. HBsAg clearance was noted in six patients (4.3%). PEG IFN-α-2a is effective in young female patients. © 2016 The Japan Society of Hepatology.

We used hepatic balance and tracer ([3H]glucose) techniques to examine the impact of “breakfast” on hepatic glucose metabolism later in the same day. From 0–240 min, 2 groups of conscious dogs (n = 9 dogs/group) received a duodenal infusion of glucose (GLC) or saline (SAL), then were fasted from 240–360 min. Three dogs from each group were euthanized and tissue collected at 360 min. From 360–600 min, the remaining dogs underwent a hyperinsulinemic (4× basal) hyperglycemic clamp (arterial blood glucose 146 ± 2 mg/dL) with portal GLC infusion. The total GLC infusion rate was 14% greater in dogs infused with GLC than in those receiving SAL (AUC360–600min 2,979 ± 296 vs. 2,597 ± 277 mg/kg, respectively). The rates of hepatic glucose uptake (5.8 ± 0.8 vs. 3.2 ± 0.3 mg ⋅ kg−1 ⋅ min−1) and glycogen storage (4.7 ± 0.6 vs. 2.9 ± 0.3 mg ⋅ kg−1 ⋅ min−1) during the clamp were markedly greater in dogs receiving GLC compared with those receiving SAL. Hepatic glycogen content was ∼50% greater, glycogen synthase activity was ∼50% greater, glycogen phosphorylase activity was ∼50% lower, and the amount of phosphorylated glycogen synthase was 34% lower, indicating activation of the enzyme, in dogs receiving GLC compared with those receiving SAL. Thus, morning GLC primed the liver to extract and store more glucose in the presence of hyperinsulinemic hyperglycemia later in the same day, indicating that breakfast enhances the liver’s role in glucose disposal in subsequent same-day meals.

Objectives. We evaluated the efficacy of a hepatitis care coordination intervention to improve linkage to hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccination and clinical evaluation of hepatitis C virus (HCV) infection among methadone maintenance patients. Methods. We conducted a randomized controlled trial of 489 participants from methadone maintenance treatment programs in San Francisco, California, and New York City from February 2008 through June 2011. We randomized participants to a control arm (n = 245) and an intervention arm (n = 244), which included on-site screening, motivational-enhanced education and counseling, on-site vaccination, and case management services. Results. Compared with the control group, intervention group participants were significantly more likely (odds ratio [OR] = 41.8; 95% confidence interval [CI] = 19.4, 90.0) to receive their first vaccine dose within 30 days and to receive an HCV evaluation within 6 months (OR = 4.10; 95% CI = 2.35, 7.17). A combined intervention adherence outcome that measured adherence to HAV–HBV vaccination, HCV evaluation, or both strongly favored the intervention group (OR = 8.70; 95% CI = 5.56, 13.61). Conclusions. Hepatitis care coordination was efficacious in increasing adherence to HAV–HBV vaccination and HCV clinical evaluation among methadone patients. PMID:23947319

Infection with hepatitis A and hepatitis B virus can increase the risk of morbidity and mortality in persons with chronic liver disease (CLD). The Advisory Committee on Immunization Practices recommends hepatitis A (HepA) and hepatitis B (HepB) vaccination for persons with CLD. Data from the 2014 and 2015 National Health Interview Surveys (NHIS), nationally representative, in-person interview surveys of the non-institutionalized US civilian population, were used to assess self-reported HepA (≥1 and ≥2 doses) and HepB vaccination (≥1 and ≥3 doses) coverage among adults who reported a chronic or long-term liver condition. Multivariable logistic regression was used to identify factors independently associated with HepA and HepB vaccination among adults with CLD. Overall, 19.4% and 11.5% of adults aged ≥ 18 years with CLD reported receiving ≥1 dose and ≥2 doses of HepA vaccine, respectively, compared with 14.7% and 9.1% of adults without CLD (p < .05 comparing those with and without CLD, ≥1dose). Age, education, geographic region, and international travel were associated with receipt of ≥2 doses HepA vaccine among adults with CLD. Overall, 35.7% and 29.1% of adults with CLD reported receiving ≥1 dose and ≥3 doses of HepB vaccine, respectively, compared with 30.2% and 24.7% of adults without CLD (p < .05 comparing those with and without CLD, ≥1 dose). Age, education, and receipt of influenza vaccination in the past 12 months were associated with receipt of ≥3 doses HepB vaccine among adults with CLD. Among adults with CLD and ≥10 provider visits, only 13.8% and 35.3% had received ≥2 doses HepA and ≥3 doses HepB vaccine, respectively. HepA and HepB vaccination among adults with CLD is suboptimal and missed opportunities to vaccinate occurred. Providers should adhere to recommendations to vaccinate persons with CLD to increase vaccination among this population. Copyright © 2018 Elsevier Ltd. All rights reserved.

Hispanic immigrant/migrant men who have sex with men (MSM) should be at higher risk for sexually transmitted infections/human immunodeficiency virus (STIs/HIV) given individual-level factors associated with the migration process that have been theorised to increase susceptibility to STIs/HIV among migrant populations. However, relatively little is known if these individual level factors are actually associated with the STI prevalence among this population. During 2005-2007, 2576 men and women foreign-born Hispanics were surveyed at three community-based organisations offering services to immigrant/migrant communities in the US. We analysed demographic characteristics, sexual risk behaviours, migration patterns, and factors associated with STI diagnoses (syphilis, chlamydia, and gonorrhoea) in the past 12 months among Hispanic immigrant/migrant MSM. Of 1482 Hispanic immigrant/migrant men surveyed who reported having sex in the past 12 months, 353 (24%) reported sex with a man, and of these, 302 answered questions regarding whether or not they had been diagnosed with a bacterial STI in the past year. Of these 302 men, 25% reported being married; 42% self-identified as being heterosexual and 20% as bisexual. Twenty-nine (9.6%) men reported that they had received an STI diagnosis in the past year. In the multivariate logistic regression model, men who reported receiving money or goods for sex had increased odds of a self-reported STI diagnosis. The prevalence of bacterial STIs among Hispanic immigrant/migrant MSM is lower than the prevalence of bacterial STIs among other MSM in the United States. Nevertheless, receiving money or goods for sex was significantly associated with a self-reported STI diagnosis among Hispanic immigrant/migrant MSM. It is important to understand factors contributing to participation in exchange sex among this population. HIV/STI prevention interventions tailored to non-gay identifying MSM are important for Hispanic immigrant/migrant MSM. �

Acute viral hepatitis (AVH) is a major public health problem and is an important cause of morbidity and mortality. The aim of the present study is to determine the prevalence of hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and hepatitis E virus (HEV) as causes of AVH in a tertiary care hospital of North India. Blood samples and clinical information was collected from cases of AVH referred to the Grade I viral diagnostic laboratory over a 1-year period. Samples were tested for hepatitis B surface antigen, anti-HCV total antibodies, anti-HAV immunoglobulin M (IgM) and anti-HEV IgM by the enzyme-linked immunosorbent assay. PCR for nucleic acid detection of HBV and HCV was also carried out. Those positive for HBV infection were tested for anti-HDV antibodies. Fisher's exact test was used and a P < 0.05 was considered to be statistically significant. Of the 267 viral hepatitis cases, 62 (23.22%) patients presented as acute hepatic failure. HAV (26.96%) was identified as the most common cause of acute hepatitis followed by HEV (17.97%), HBV (16.10%) and HCV (11.98%). Co-infections with more than one virus were present in 34 cases; HAV-HEV co-infection being the most common. HEV was the most important cause of acute hepatic failure followed by co-infection with HAV and HEV. An indication towards epidemiological shift of HAV infection from children to adults with a rise in HAV prevalence was seen. To the best of our knowledge, this is the first report indicating epidemiological shift of HAV in Uttar Pradesh.

we aimed to investigate the accuracy of liver (LSM) spleen stiffness measurement (SSM) with transient elastography (TE) to predict varices in the presence of non-selective beta-blockers (NSBB). In this cross-sectional study of consecutive patients with chronic hepatitis B (CHB) and cirrhosis, all patients underwent TE and upper endoscopic examinations. LSM and SSM in predicting varices in patients receiving and not receiving NSBB were evaluated. Altogether 144 CHB patients (29 receiving NSBB; 35 with any varices, 31 and 11 with esophageal and gastric varices, respectively) were recruited. Their mean LSM and SSM were 13.3 ± 9.0 kPa and 32.8 ± 19.2 kPa, respectively. The correlation between LSM and SSM was better in the NSBB subgroup (r = 0.525, P = 0.003) than its counterpart (r = 0.329, P  < 0.001). The area under receiver operating characteristic curve (AUROC) of LSM and SSM for any varices was 0.675 and 0.685 (P = 0.002 and 0.001), respectively. SSM of 18.9 kPa had a negative predictive value of 92.1% and negative likelihood ratio of 0.27 for ruling out any varices; and SSM of 54.9 kPa had a positive predictive value of 56.5% and a positive likelihood ratio of 4.05 to rule in varices. The AUROC of LSM for varices was 0.742 and 0.549 in patients with or without NSBB, respectively; the corresponding AUROC of SSM was 0.572 and 0.603, respectively. SSM only has modest accuracy to predict varices independent of NSBB use. An SSM cutoff value of 18.9 kPa may be adopted to achieve a high negative predictive value to rule out varices. © 2016 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

We evaluated the clinical and virological characteristics of hepatitis A virus infection in persons concomitantly infected with hepatitis B virus (HBV) or hepatitis C virus (HCV). We enrolled 21 patients with acute hepatitis A and chronic hepatitis with no sign of liver cirrhosis, 13 patients who were positive for hepatitis B surface antigen (case B group), 8 patients who were anti-HCV positive (case C group), and 21 patients with acute hepatitis A without a preexisting liver disease (control A group). Two control groups of patients with chronic hepatitis B (control B group) or C (control C group) were also chosen. All control groups were pair-matched by age and sex with the corresponding case group. Fulminant hepatitis A was never observed, and hepatitis A had a severe course in 1 patient in the case B group and in 1 patient in the control A group. Both patients recovered. On admission, HBV DNA was detected in 1 patient in the case B group (7.7%) and in 13 patients (50%) in the control B group; HCV RNA was found in no patient in the case C group and in 16 patients (81.2%) in the control C group. Of 9 patients in the case B group who were followed up for 6 months, 3 became negative for hepatitis B surface antigen and positive for hepatitis B surface antibody, 2 remained positive for hepatitis B surface antigen and negative for HBV DNA, and 4 became positive for HBV DNA with a low viral load [corrected] Of 6 patients in the case C group who were followed up for 6 months, 3 remained negative for HCV RNA, and 3 had persistently low viral loads. Concomitant hepatitis A was always self-limited, associated with a marked inhibition of HBV and HCV genomes, and possibly had a good prognosis for the underlying chronic hepatitis.

To prepare a soluble gelatin sponge (GS) and to explore the GS particles (GSPs) that inhibit development of collateral pathways when transcatheter hepatic arterial embolization is performed. The approval of the Institutional Committee on Research Animal Care of our institution was obtained. By means of 50 and 100 kDa of regenerative medicine-gelatin (RM-G), RM-G sponges were prepared by freeze-drying and heating to temperatures of 110-150{sup o}C for cross-linkage. The soluble times of RM-GSPs were measured in vitro. Eight swine for transcatheter hepatic arterial embolization were assigned into two groups: six received 135{sup o}C/50RM-GSPs, 125{sup o}C/100RM-GSPs, and 138{sup o}C/50RM-GSPs, with solublemore » time of 48 h or more in vitro; two swine received Gelpart GSPs (G-GSPs) with insoluble time of 14 days as a control. Transarterial chemoembolization was performed on two branches of the hepatic artery per swine. RM-GSPs heated at temperatures of 110-138{sup o}C were soluble. Mean soluble times of the RM-GSPs increased with higher temperature. Hepatic branches embolized with G-GSP remained occluded after 6 days, and development of collateral pathways was observed after 3 days. Hepatic branches embolized with 135{sup o}C/50RM-GSP and 125{sup o}C/100RM-GSP remained occluded for 4 h, and recanalization was observed after 1 day. Hepatic branches embolized with 138{sup o}C/50RM-GS remained occluded for 1 day, and recanalization was observed after 2 days with no development of collateral pathways. In RM-GSs with various soluble times that were prepared by modulating the heating temperature, 138{sup o}C/50RM-GSP was the soluble GSP with the longest occlusion time without inducing development of collateral pathways.« less

To describe the increased incidence of sexually transmitted infections (STIs) in a cohort of HIV-infected men who have sex with men (MSM), followed in a tertiary hospital of the Île-de-France region. We performed a monocentric, retrospective, and prospective study. We included symptomatic HIV-infected MSM patients who consulted for their annual consultation. One hundred and eighty patients were seen between 2008-2011 and 215 between 2012-2015. We observed an increased incidence of STIs between the two periods (14 and 29.3%, respectively). These STIs includes: syphilis, hepatitis C, urethritis, and proctitis due to Chlamydia trachomatis and Neisseria gonorrhea. A better management of symptomatic and asymptomatic STIs is needed for HIV-infected MSM patients. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

The suppression of endogenous glucose production during parenteral nutrition is impaired in critically ill patients. It is, however, unknown whether enteral administration of carbohydrates, which normally promote hepatic glucose uptake, improves hepatic glucose metabolism in such patients. We studied two groups of 7 patients during a 3-day continuous isocaloric enteral nutrition. A high-carbohydrate, low-lipid (EN-C) or a high-lipid, low-carbohydrate (EN-L) nutrient mixture was administered. Endogenous glucose production assessed with [2H7]glucose was similarly increased in both groups, indicating absence of its suppression by carbohydrate feeding. Gluconeogenesis estimated from [13C]glucose synthesis during [13C]bicarbonate infusion also was not suppressed by EN-C compared with EN-L. Systemic appearance of exogenous glucose was monitored by enteral infusion of [6,6-2H]glucose and was not different from the rate of glucose equivalent administered enterally, indicating no significant hepatic uptake of glucose in both groups. Plasma glucose and insulin concentrations were slightly higher with EN-C, although not significantly, and plasma triglycerides were similar in both groups. Both nutrition formulas were well tolerated clinically. These results indicate that enteral carbohydrate administration, whatever its quantity, fails to suppress endogenous glucose production and to promote net splanchnic glucose uptake in critically ill patients.

Autoantibodies are commonly detected in chronic hepatitis C (HCV) but their significance remains uncertain. We assessed the prevalence of anti-nuclear (ANA) and anti-smooth muscle (ASM) antibodies within a cohort of 963 treatment-naïve HCV patients. We also assessed for differences between autoantibody-positive and autoantibody-negative patients in demographics, markers of disease activity and response to anti-viral treatment. One hundred and seventy-two patients (17.9%) had at least one autoantibody, of which were 104 (10.8%) ASM, 54 (5.6%) ANA and 14 (1.5%) positive for both. Autoantibody-positive patients were older (43 vs 39 years, P = 0.001) caused by an age-related increase in ANA (but not ASM). There were no differences in gender, alcohol intake, ethnicity or viral genotype. The presence of autoantibodies, and specifically ASM, was associated with an increase in interface hepatitis score amongst men (1.1 vs 0.8, P = 0.005) but no difference in other necroinflammatory measures, liver function tests or immunoglobulins (Ig). There was no difference in initial fibrosis stage or rate of fibrosis progression. Autoantibodies did not affect response to anti-viral treatment. We conclude that autoantibodies are frequent in HCV infection. Anti-nuclear antibodies increase with age, whereas ASM antibodies are associated with interface hepatitis in men. Neither autoantibody carries increased risk of fibrosis progression or failure of therapy.

This document represents the position of the Chilean Infectious Diseases Society Advisory Committee on Immunization Practices regarding hepatitis A epidemiological situation in Chile. The recommendations are based on local epidemiological data, the hepatitis A virus infection characteristics and the global experience with the available vaccines. In relation to hepatitis A, Chile is no longer a highly endemic area but actually an intermediate one, currently concentrating cases in individuals over 15 years of age, with frequent outbreaks. In 2017 we have seen an important outbreak of genotype 1A in men who have sex with men (MSM). The current endemic, the presence of regular outbreaks, the frequency of natural disasters in Chile, together with the availability of safe, effective vaccines and local cost-effectiveness studies led us to propose measures for outbreak control for high risk groups protection and mid and long term, including a more definitive solution which is universal vaccination against this disease in small children.

Viral hepatitis is a serious health problem all over the world. However, the reduction of the morbidity and mortality due to vaccinations against hepatitis A and hepatitis B has been a major component in the overall reduction in vaccine preventable diseases. We will discuss the epidemiology, vaccine development, and post-vaccination effects of the hepatitis A and B virus. In addition, we discuss attempts to provide hepatitis D vaccine for the 350 million individuals infected with hepatitis B globally. Given the lack of a hepatitis C vaccine, the many challenges facing the production of a hepatitis C vaccine will be shown, along with current and former vaccination trials. As there is no current FDA-approved hepatitis E vaccine, we will present vaccination data that is available in the rest of the world. Finally, we will discuss the existing challenges and questions facing future endeavors for each of the hepatitis viruses, with efforts continuing to focus on dramatically reducing the morbidity and mortality associated with these serious infections of the liver.

Diets high in fructose have been proposed to contribute to nonalcoholic fatty liver disease. We compared the effects of high-fructose and matched glucose intake on hepatic triacylglycerol (TAG) concentration and other liver parameters. In a double-blind study, we randomly assigned 32 healthy but centrally overweight men to groups that received either a high-fructose or high-glucose diet (25% energy). These diets were provided during an initial isocaloric period of 2 weeks, followed by a 6-week washout period, and then again during a hypercaloric 2-week period. The primary outcome measure was hepatic level of TAG, with additional assessments of TAG levels in serum and soleus muscle, hepatic levels of adenosine triphosphate, and systemic and hepatic insulin resistance. During the isocaloric period of the study, both groups had stable body weights and concentrations of TAG in liver, serum, and soleus muscle. The high-fructose diet produced an increase of 22 ± 52 μmol/L in the serum level of uric acid, whereas the high-glucose diet led to a reduction of 23 ± 25 μmol/L (P < .01). The high-fructose diet also produced an increase of 0.8 ± 0.9 in the homeostasis model assessment of insulin resistance, whereas the high-glucose diet produced an increase of only 0.1 ± 0.7 (P = .03). During the hypercaloric period, participants in the high-fructose and high-glucose groups had similar increases in weight (1.0 ± 1.4 vs 0.6 ± 1.0 kg; P = .29) and absolute concentration of TAG in liver (1.70% ± 2.6% vs 2.05% ± 2.9%; P = .73) and serum (0.36 ± 0.75 vs 0.33 ± 0.38 mmol/L; P = .91), and similar results in biochemical assays of liver function. Body weight changes were associated with changes in liver biochemistry and concentration of TAGs. In the isocaloric period, overweight men who were on a high-fructose or a high-glucose diet did not develop any significant changes in hepatic concentration of TAGs or serum levels of liver enzymes.

Non-operative management of isolated blunt hepatic trauma is recommended except when hemodynamic instability requires immediate laparotomy. Hepatic artery angioembolization is increasingly used for hepatic injuries with ongoing bleeding as demonstrated by contrast extravasation on the CT scan. It is used primarily or after laparotomy to control ongoing hemorrhage. Hepatic angioembolization as part of multimodality management of hepatic trauma is reported mainly in adults, with few pediatric case reports. We describe our institution experience with primary pediatric hepatic angioembolization and review the literature with regard to indications and complications. Two cases (3 and 8 years old), with high-grade blunt hepatic injuries with contrast extravasation on the CT scan were successfully managed by emergency primary hepatic angioembolization with minimal morbidity and avoided laparotomy. To date, the only reports of pediatric hepatic angioembolization for trauma are 5 cases for acute bleeding and 15 delayed cases for pseudoaneurysm. The role of hepatic angioembolization in the presence of an arterial blush on CT in adults is accepted, but contested in a pediatric series, despite higher transfusion rate and mortality rate. We propose that hepatic angioembolization should be considered adjunct treatment, in lieu of, or in addition to emergency laparotomy for hemostasis in pediatric blunt hepatic injury.

This Phase-IV study evaluated the human rotavirus (RV) vaccine Rotarix (RIX4414) to provide additional local clinical data to the Taiwan Food and Drug Association (NCT01198769). Healthy infants aged 6-12 weeks who were given a hepatitis B immunoglobulin (HBIg) dose after birth, received two doses of RIX4414 (0, 2-month schedule). Anti-RV IgA antibody concentrations were measured using ELISA. A total of 15 infants were enrolled, and included in the according-to-protocol cohort. The anti-RV IgA antibody seroconversion rate 2 months post-Dose 2 was 100% (95% confidence interval = 78.2-100) and the geometric mean concentration was 254.7 U/ml (95% confidence interval = 145.0-447.7). Two episodes of gastroenteritis were reported, and one stool sample was tested for RV, which was negative. No fatal serious adverse events were reported during the study period between November 2010 and April 2011. The two-dose regimen of RIX4414 was highly immunogenic and safe when administered to healthy Taiwanese infants who received a HBIg dose after birth. NCT01198769. Copyright © 2012.

Hepatic inflammation may affect the performance of FibroScan. This prospective study investigated the influence of hepatic inflammation on liver stiffness measurement (LSM) values by assessing FibroScan and liver biopsy findings in 325 patients with chronic hepatitis B. Liver fibrosis and inflammation were classified into five stages (S0-S4) and grades (G0-G4) according to the Scheuer scoring system. LSM values were correlated with fibrosis stage and inflammation grade (r = 0.479, p < 0.001, and r = 0.522, p < 0.001, respectively). Although LSM values increased in parallel with inflammation grade, no significant differences were found between patients with significant fibrosis (S2-S4) (p > 0.05). For inflammation grades G0, G1, G2 and G3, areas under receiver operating characteristic curves of FibroScan for significant fibrosis were 0.8267 (p < 0.001), 0.6956 (p < 0.001), 0.709 (p = 0.0012) and 0.6947 (p = 0.137), respectively. Inflammation has a significant influence on LSM values in patients with chronic hepatitis B with mild fibrosis, but not in those with significant fibrosis.

A previously healthy 44-year-old woman presented with 3 days of worsening petechial rash, epistaxis and fatigue. Admission labs revealed pancytopenia, low reticulocyte index and elevated liver enzymes. Bone marrow biopsy demonstrated a profoundly hypocellular bone marrow without dysplasia and additional testing demonstrated an acute hepatitis B infection. In the context of an acute hepatitis B infection, elevated liver enzymes and aplastic anaemia, our patient was diagnosed with severe hepatitis-associated aplastic anaemia due to an acute hepatitis B infection. She was initiated on antiviral therapy with tenofovir and briefly received immunosuppressive therapy with a robust sustained improvement in her blood counts. Acute hepatitis B-associated aplastic anaemia is an exceptionally rare presentation of aplastic anaemia. We present acute hepatitis B-associated aplastic anaemia that resolved with antiviral therapy, which to our knowledge is the second such case reported in the literature and the first using tenofovir. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

The objectives of this study were to estimate the point prevalence of sexually transmitted infection (STI) and to investigate the sexual practices and behaviours associated with STIs in a group of gay men, other men who have sex with men and transgender women (GMT) in the province of La Romana, Dominican Republic. A cross-sectional study of a convenience sample of GMT persons. The study was conducted in the province of La Romana, Dominican Republic, in June-July 2013. Out of 117 GMT persons screened, a total of 100 completed the study. Participants had to be at least 18 years of age, reside in La Romana and have had sex with another man in the preceding 12 months. All participants were interviewed and tested for STI. The main outcome of interest was the detection of any STI (HIV, herpes simplex virus type 2 (HSV-2), syphilis, hepatitis B or C) by serology. Among 100 participants, the median age was 22 years (range 18-65). One-third had consumed illicit drugs the preceding year and only 43% consistently used condoms. Prevalence was 38% for HSV-2, 5% for HIV and 13% for syphilis. There were no cases of hepatitis B or C. Factors associated with the odds of a STI were age >22 years (OR=11.1, 95% CI 3.6 to 34.5), receptive anal intercourse (OR=4.2, 95% CI 1.3 to 13.6) and having ≥2 male sexual partners during the preceding month (OR=4, 95% CI 1.3 to 12.5). In this group of GMT persons, seroprevalence of STI was high, and a number of risk behaviours were associated with STI. These preliminary data will help inform policy and programmes to prevent HIV/STI in GMT persons in the region. Published by the BMJ Publishing Group Limited.

Context: The ability of insulin to suppress hepatic glucose production is impaired among subjects with increased intrahepatic triglycerides (IHTG). However, little is known about the roles of insulin on the supporting fluxes of glucose production among patients with fatty liver. Objective: To evaluate the effects of insulin on fluxes through the three potential sources of plasma glucose (glycerol, the citric acid cycle, and glycogen) among patients with fatty liver. Design, Settings, Participants, and Intervention: Nineteen men with a range of IHTG (∼0.5% to 23%) were studied after an overnight fast and during hyperinsulinemia using magnetic resonance spectroscopy and stable isotope tracers. Main Outcome Measures: IHTG, gluconeogenesis from glycerol, gluconeogenesis from the citric acid cycle, glycogenolysis, and 13C-labeled glucose produced from the citric acid cycle during hyperinsulinemia were measured. Results: Men with high IHTG had higher fluxes through all pathways contributing to glucose production during hyperinsulinemia, compared to men with low IHTG, but they had similar fluxes after the fast. Consequently, men with fatty liver had impaired insulin efficiency in suppressing total glucose production as well as fluxes through all three biochemical pathways contributing to glucose. The detection of glucose isotopomers with 13C arising from [U-13C3]propionate ingested during hyperinsulinemia demonstrated continuous gluconeogenesis from the citric acid cycle in all subjects. Conclusions: These findings challenge the concept that individual glucose production pathways are selectively dysregulated during hepatic insulin resistance. Overproduction of glucose during hyperinsulinemia in men with fatty liver results from inadequate suppression of all the supporting fluxes of glucose production in response to insulin. PMID:25250633

Rituximab-based treatment, HCV replication, and hepatic flares.

Rituximab, a chimeric mouse-human monoclonal antibody directed to the CD20 antigen expressed on pre-B lymphocytes and mature lymphocytes, causes a profound B-cell depletion. Due to its peculiar characteristics, this drug has been used to treat oncohaematological diseases, B cell-related autoimmune diseases, rheumatoid arthritis, and, more recently, HCV-associated mixed cryoglobulinaemic vasculitis. Rituximab-based treatment, however, may induce an increased replication of several viruses such as hepatitis B virus, cytomegalovirus, varicella-zoster virus, echovirus, and parvovirus B19. Recent data suggest that rituximab-based chemotherapy induces an increase in HCV expression in hepatic cells, which may become a target for a cell-mediated immune reaction after the withdrawal of treatment and the restoration of the immune control. Only a few small studies have investigated the occurrence of HCV reactivation and an associated hepatic flare in patients with oncohaematological diseases receiving R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). These studies suggest that the hepatic flares are frequently asymptomatic, but life-threatening liver failure occurs in nearly 10% of cases.

Summary Aspects of osteoporosis in men, such as screening and identification strategies, definitions of diagnosis and intervention thresholds, and treatment options (both approved and in the pipeline) are discussed. Introduction Awareness of osteoporosis in men is improving, although it remains under-diagnosed and under-treated. A European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) workshop was convened to discuss osteoporosis in men and to provide a report by a panel of experts (the authors). Methods A debate with an expert panel on preselected topics was conducted. Results and Conclusions Although additional fracture data are needed to endorse the clinical care of osteoporosis in men, consensus views were reached on diagnostic criteria and intervention thresholds. Empirical data in men display similarities with data acquired in women, despite pathophysiological differences, which may not be clinically relevant. Men should receive treatment at a similar 10-year fracture probability as in women. The design of mixed studies may reduce the lag between comparable treatments for osteoporosis in women becoming available in men. PMID:23201268

Because of the paucity of information regarding metabolic effects of advanced glycation end products (AGEs) on liver, we evaluated effects of AGEs chronic administration in (1) insulin sensitivity; (2) hepatic expression of genes involved in AGEs, glucose and fat metabolism, oxidative stress and inflammation and; (3) hepatic morphology and glycogen content. Rats received intraperitoneally albumin modified (AlbAGE) or not by advanced glycation for 12 weeks. AlbAGE induced whole-body insulin resistance concomitantly with increased hepatic insulin sensitivity, evidenced by activation of AKT, inactivation of GSK3, increased hepatic glycogen content, and decreased expression of gluconeogenesis genes. Additionally there was reduction in hepatic fat content, in expression of lipogenic, pro-inflamatory and pro-oxidative genes and increase in reactive oxygen species and in nuclear expression of NRF2, a transcription factor essential to cytoprotective response. Although considered toxic, AGEs become protective when administered chronically, stimulating AKT signaling, which is involved in cellular defense and insulin sensitivity.

The primary romantic relationship plays a fundamental role in health maintenance, but little is known about its role in HIV care engagement among young Black men who have sex with men (MSM) living with HIV. We examined how HIV care engagement outcomes (i.e., having a primary healthcare provider, receiving HIV treatment, taking antiretroviral medication, and medication adherence) vary by partnership status (single vs. concordant-positive vs. discordant) in a sample of young Black MSM living with HIV. Results showed mixed findings. Partnership status was significantly associated with HIV care engagement, even after adjusting for individual, social, and structural factors. While partnered men were consistently more likely than their single counterparts to have a regular healthcare provider, to receive recent treatment, and to have ever taken antiretroviral medication, they were less likely to report currently receiving antiretroviral therapy. Moreover, men with a discordant partner reported better adherence compared to men with a concordant or no partner. The association between partnership status and HIV care engagement outcomes was not consistent across the stages of the HIV Care Continuum, highlighting the complexity in how and why young Black men living with HIV engage in HIV healthcare. Given the social context of HIV disease management, more research is needed to explicate underlying mechanisms involved in HIV care and treatment that differ by relational factors for young Black MSM living with HIV.

AIM To assess the seroprevalence of hepatitis B virus (HBV) immunity among previously vaccinated pediatric liver transplant recipients and present a case report of de novo hepatitis B infection after liver transplantation. METHODS This study focused on children with chronic liver diseases who received primary hepatitis B immunization and had a complete dataset of anti-HBs before and after liver transplantation between May 2001 and June 2017. Medical records were retrospectively reviewed for potential factors relating to HBV immunity loss. RESULTS In total, 50 children were recruited. The mean time from liver transplantation to anti-HBs testing was 2.53 ± 2.11 years. The mean anti-HBs levels before and after liver transplantation were 584.41 ± 415.45 and 58.56 ± 6.40 IU/L, respectively. The rate of non-immunity (anti-HBs < 10 IU/L) in the participants was 46% (n = 26) at one year, 57% (n = 7) at two years and 82% (n = 17) at > three years following liver transplantation. The potential factors relating to HBV immunity loss after liver transplantation were identified as anti-HBs (P = 0.002), serum albumin (P = 0.04), total bilirubin (P = 0.001) and direct bilirubin (P = 0.003) before liver transplantation. A five-year-old boy with biliary cirrhosis received 4 doses of HBV vaccine with an anti-HBs titer of > 1000 IU/L and underwent liver transplantation; his anti-HBc-negative father was the donor. After liver transplantation, the boy had stenosis of the hepatic artery up to the inferior vena cava anastomosis and underwent venoplasty three times. He also received subcutaneous injections of enoxaparin for 5 mo and 20 transfusions of blood components. Three years and ten months after the liver transplantation, transaminitis was detected with positive tests for HBsAg, HBeAg, and anti-HBc (2169.61, 1706 and 8.45, respectively; cutoff value: < 1.00) and an HBV viral load of 33212320 IU/mL.

Booster dose vaccination for preventing hepatitis B.

Antibodies against hepatitis B surface antigen (HBsAg) wane over time following hepatitis B immunisation; hence, it is unclear whether people vaccinated in three-dose or four-dose schedules of the hepatitis B vaccine are still immune when the hepatitis B surface antibody (anti-HBs) level in their body is undetectable, or lower than the level usually considered protective. This question may potentially be answered indirectly by measuring the anamnestic immune response to a booster dose of vaccine. The term 'booster' (or revaccination) refers to an additional dose of hepatitis B vaccine (HBV) given some time post-primary vaccination to induce immune memory and improve protection against hepatitis B virus (HBV) infection. To assess the benefits and harms of booster dose hepatitis B vaccination, more than five years after the primary vaccination, for preventing HBV infection in healthy individuals previously vaccinated with the hepatitis B vaccine, and with hepatitis B surface antibody (anti-HBs) levels below 10 mIU/mL. We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Science Citation Index Expanded, conference databases, and reference lists of articles to January 2016. We also contacted authors of articles. In addition, we searched ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform for ongoing trials (May 2016). Randomised clinical trials addressing anamnestic immune response to a booster dose of hepatitis B vaccine, more than five years after the primary vaccination, in apparently healthy participants, vaccinated in a three-dose or four-dose schedule of the hepatitis B vaccine during the primary vaccination, without receiving an additional dose or immunoglobulin. Both review authors decided if the identified studies met the inclusion criteria or not. Primary outcomes included the proportion of participants

To characterize adverse events (AEs) after hepatitis A vaccines (Hep A) and hepatitis A and hepatitis B combination vaccine (Hep AB) in pregnant women reported to the Vaccine Adverse Event Reporting System (VAERS), a spontaneous reporting surveillance system. We searched VAERS for AEs reports in pregnant women who received Hep A or Hep AB from Jan. 1, 1996-April 5, 2013. Clinicians reviewed all reports and available medical records. VAERS received 139 reports of AEs in pregnant women; 7 (5.0%) were serious; no maternal or infant deaths were identified. Sixty-five (46.8%) did not describe any AEs. For those women whose gestational age was available, most were vaccinated during the first trimester, 50/60 (83.3%) for Hep A and 18/21 (85.7%) for Hep AB. The most common pregnancy-specific outcomes following Hep A or Hep AB vaccinations were spontaneous abortion in 15 (10.8%) reports, elective termination in 10 (7.2%), and preterm delivery in 7 (5.0%) reports. The most common nonpregnancy specific outcome was urinary tract infection and nausea/vomiting with 3 (2.2%) reports each. One case of amelia of the lower extremities was reported in an infant following maternal Hep A immunization. This review of VAERS reports did not identify any concerning pattern of AEs in pregnant women or their infants following maternal Hep A or Hep AB immunizations during pregnancy.

Hemophilic patients require long-life intravenous infusion of factor concentrates to treat bleedings. This could increase the risk of transmission of blood-borne infections like hepatitis C. The current study was aimed at investigating the immunity status against hepatitis A in hemophilic patients in south Khorasan and evaluating the necessity of hepatitis A vaccination for this population. A cross-sectional descriptive study was conducted between 2014 and 2015 on all hemophilic patients of south Khorasan province, Iran (n = 108) for anti-HAV total, anti- HCV, HBs-Ag, anti-HIV, and anti-HTLV-I /II. Note that no one had already received a hepatitis A vaccine. As our results show, 77.8% of the participants (59% under 20 and 88.4% above 20 years old) were seropositive for anti-HAV total; 20.4% and 2.8% (three patients) of the cases were anti-HCV positive and anti-HTLV-1 positive, respectively, while none of the subjects were HBS-Ag or HIV-Ab positive. Seventeen of the patients (15.75%) showed a co-infection of HAV with HCV, and five HCV-infected patients (22.73%) had no immunity against hepatitis A. There was a significant relationship between age, rural life, and anti-HAV positive state in our patients (P < 0.001). No significant relationship between positive anti-HAV status and sex (P = 0.16), severity of hemophilia (P = 0.23), and infection with HIV, HCV, HTLV-1, and hepatitis B (P > 0.05) was detected. More than 40% of the hemophilic patients under 20 years of age in the present study had no immunity against hepatitis A, and 23% of hepatitis C patients had not had a hepatitis A co-infection yet. Since hepatitis A can show a fulminant course in hepatitis C patients, vaccination against hepatitis A seems necessary in hemophilic patients in the region.

Background: Knowledge about the travel-associated risks of hepatitis A and B, and the extent of pre-travel health-advice being sought may vary between countries. Methods: An online survey was undertaken to assess the awareness, advice-seeking behaviour, rates of vaccination against hepatitis A and B and adherence rates in Australia, Finland, Germany, Norway, Sweden, the UK and Canada between August and October 2014. Individuals aged 18–65 years were screened for eligibility based on: travel to hepatitis A and B endemic countries within the past 3 years, awareness of hepatitis A, and/or combined hepatitis A&B vaccines; awareness of their self-reported vaccination status and if vaccinated, vaccination within the last 3 years. Awareness and receipt of the vaccines, sources of advice, reasons for non-vaccination, adherence to recommended doses and the value of immunization reminders were analysed. Results: Of 27 386 screened travellers, 19 817 (72%) were aware of monovalent hepatitis A or combined A&B vaccines. Of these 13 857 (70%) had sought advice from a healthcare provider (HCP) regarding combined hepatitis A&B or monovalent hepatitis A vaccination, and 9328 (67%) were vaccinated. Of 5225 individuals eligible for the main survey (recently vaccinated = 3576; unvaccinated = 1649), 27% (841/3111) and 37% (174/465) of vaccinated travellers had adhered to the 3-dose combined hepatitis A&B or 2-dose monovalent hepatitis A vaccination schedules, respectively. Of travellers partially vaccinated against combined hepatitis A&B or hepatitis A, 84% and 61%, respectively, believed that they had received the recommended number of doses. Conclusions: HCPs remain the main source of pre-travel health advice. The majority of travellers who received monovalent hepatitis A or combined hepatitis A&B vaccines did not complete the recommended course. These findings highlight the need for further training of HCPs and the provision of reminder services to improve traveller

HCPs remain the main source of pre-travel health advice. The majority of travellers who received monovalent hepatitis A or combined hepatitis A&B vaccines did not complete the recommended course. These findings highlight the need for further training of HCPs and the provision of reminder services to improve traveller awareness and adherence to vaccination

A randomized clinical trial of hepatitis A vaccines (1 or 2 doses of inactivated vaccine [Healive] or 1 dose of live attenuated vaccine [Biovac]) was conducted among adults to evaluate seroprotection rates and geometric mean concentrations of antibody against hepatitis A virus for 36 months. High rates of seroprotection persisted for at least 36 months among adults who received 1 or 2 doses of inactivated hepatitis A vaccine but not among adults who received 1 dose of live attenuated hepatitis A vaccine. The long-term serial monitoring of immunogenicity induced by 1 dose of inactivated hepatitis A vaccine is needed to determine an effective alternative to a 2-dose schedule.

We measured the prevalence of international travel, the demographic and risk profile of international travellers and risk and preventive behaviours of travellers among HIV-negative and HIV-positive men who have sex with men (MSM), based in San Francisco, CA, USA, through the addition of questions to the local implementation of the National HIV Behavioral Surveillance survey in 2008. Of 270 MSM participating in the survey, slightly more than one-quarter (26.3%) had travelled internationally in the last year. Those with a history of international travel were more likely to be foreign born, of a higher socioeconomic status and HIV uninfected. Of eight HIV-positive MSM who travelled internationally (11.3% of HIV-positive MSM), all were on antiretroviral therapy and only three recalled being vaccinated for hepatitis A and B. Human papillomavirus infection was also higher among international travellers. Travel health services must be improved to address special needs of this population of international travellers.

To measure hepatitis B virus (HBV) infection rates among injection drug users in Rio de Janeiro, Brazil, and to report their knowledge of and attitudes toward hepatitis and HBV vaccination. 609 injection drug users recruited in Rio de Janeiro between 1999 and 2001 answered a questionnaire and were tested for hepatitis B and other blood-borne infections. Questions covered sociodemographic information, alcohol and illicit drug consumption, drug injection and sexual practices, medical history, and knowledge about HIV, AIDS and viral hepatitis. The prevalence of HBV infection was 27.1%, with 3.4% of the sample positive for HbsAg (active infection) and 0.8% positive for anti-HBs (indicating previous HBV vaccination). Most interviewees (81.3%) were aware of at least one form of viral hepatitis and received information from many different sources. In agreement with laboratory findings, 96.7% of the interviewees stated they had never been vaccinated against hepatitis B, but almost all unvaccinated interviewees (97.8%) said they would volunteer to be vaccinated if HBV vaccination were available. Few of the injection drug users surveyed had ever been vaccinated against HBV. Although most were aware of the risks posed by viral hepatitis, this awareness seldom translated into consistent behavioral change. The participants' willingness to be vaccinated against HBV suggests that the implementation of vaccination for this population may help decrease rates of hepatitis B infection.

The timing and best regimen for a booster dose of hepatitis B vaccine have not been determined. Two studies were conducted to determine the response to a booster dose of 5 micrograms recombinant hepatitis B vaccine. In the first study, a 5 micrograms (0.5 ml) dose of Recombivax HB was administered intramuscularly 38 months after the initial dose to 71 volunteers. In a second study, we offered a 5 micrograms dose recombinant hepatitis B vaccine, either Recombivax HB (0.5 ml) or Engerix B (0.25 ml), to students who had previously been immunized with three doses of vaccine. In the first study, among the 44 persons for whom postbooster sera were available, the geometric mean concentration of anti-hepatitis B surface antigens increased from 42 to 2090 mIU/ml after the 5 micrograms (0.5 ml) dose of Recombivax. In the second study, after a 5 micrograms (0.5 ml) dose of Recombivax, the geometric mean concentration increased from 43 to 990 mIU/ml (n = 48), and in the group that received a 5 micrograms (0.25 ml) dose of Engerix B, the concentration increased from 83 to 2337 mIU/ml (n = 45) (p = 0.18 for postdose concentrations). A 5 micrograms dose of recombinant vaccine results in an excellent booster response at a cost one fourth to one half that of a full 1 ml dose of vaccine.

Recent studies have shown that radiofrequency (RF) ablation therapy is a safe, feasible, and effective procedure for hepatic hemangiomas, even huge hepatic hemangiomas. RF ablation has the following advantages in the treatment of hepatic hemangiomas: minimal invasiveness, definite efficacy, high safety, fast recovery, relatively simple operation, and wide applicability. It is necessary to formulate a widely accepted consensus among the experts in China who have extensive expertise and experience in the treatment of hepatic hemangiomas using RF ablation, which is important to standardize the application of RF ablation for the management of hepatic hemangiomas, regarding the selection of patients with suitable indications to receive RF ablation treatment, the technical details of the techniques, therapeutic effect evaluations, management of complications, etc. A final consensus by a Chinese panel of experts who have the expertise of using RF ablation to treat hepatic hemangiomas was reached by means of literature review, comprehensive discussion, and draft approval.

Autoimmune thyroid disorders (AITDs) are reported, especially during interferon treatment, in chronic HCV infection, in which non-organ-specific autoantibodies (NOSAs) are common. We wondered whether seropositivity for NOSA is associated with susceptibility to AITDs. We evaluated thyroid function and antithyroglobulin and antithyroperoxidase antibodies in 348 Italian patients with chronic hepatitis C (34% NOSA-positive), 196 patients (33% NOSA-positive) of whom received interferon treatment. At baseline, thyroid disorders were significantly more frequent in liver/kidney microsomal antibody type 1 (LKM1)-positive patients (29% vs 9%, P < .005). Similarly, on interferon therapy de novo autoimmune thyroid markers and/or symptomatic thyroid disorders appeared more often in LKM1-positive patients (50% vs 3%, P < .0001). Both female sex and LKM1 positivity were predictors of AITD, but only the latter remained significant after logistic regression analysis. Cross-reactivity to all 7 linear epitopes encoding homologous amino acid sequences shared by the HCV polyprotein, CYP2D6 (the LKM1 autoantigen), and thyroperoxidase was detected in 86% LKM1-positive HCV patients with clinical thyroid disorders, but in none of the LKM1-positive or negative HCV patients without thyroid disease, and none of an HCV-negative control group comprising subjects with LKM1-positive autoimmune hepatitis or AITD without liver disease ( P < .0001). Patients receiving interferon therapy for hepatitis C seropositive for LKM1 are susceptible to develop AITDs, in association with treatment. Molecular mimicry and epitope spreading are potential pathogenic mechanisms.

The quadrivalent meningococcal conjugate vaccine (MenACWY-CRM) has been introduced for military recruits in Korea since 2012. This study was performed to evaluate the immunogenicity of MenACWY-CRM in Korean military recruits. In addition, the influence of tetanus-diphtheria toxoids (Td) vaccination on the vaccine response to MenACWY-CRM was analyzed. A total of 75 military recruits were enrolled. Among them, 18 received a dose of MenACWY-CRM only (group 1), and 57 received Td three days before MenACWY-CRM immunization (group 2). The immunogenicity of MenACWY-CRM was compared between the two groups. The serum bactericidal activity with baby rabbit complement was measured before and three weeks after immunization against serogroups A, C, W-135, and Y. The geometric mean titers (GMTs) against four serogroups were significantly increased in both groups after immunization. Compared to group 2, group 1 exhibited significantly higher vaccine responses in several aspects: post-immune GMTs against serogroup A and C, seroresponse rates against serogroup A, and a fold increases of titers against serogroup A, C, and Y. MenACWY-CRM was immunogenic against all vaccine-serogroups in Korean military recruits. Vaccine response to MenACWY-CRM was influenced by Td administered three days earlier.

A study is currently underway to investigate the efficacy of interferon therapy in patients with prolonged (greater than or equal to 10 weeks but less than 6 months) hepatitis B infection. To date, a total of 15 patients have been enrolled in the study and randomly assigned to receive either placebo for 24 weeks (n = 8) or interferon 5 million units subcutaneously 3 times a week for 24 weeks (n = 7), with follow up for 1 year. Thirteen patients have completed the follow-up period: seven patients in the placebo group and six in the treated group. Five of the six treated patients completely eradicated the infection during interferon therapy, with clearance of hepatitis B e and surface antigens, and seroconversion to antibody positivity in each case. Two of the eight placebo patients seroconverted during the placebo period. Clearance of hepatitis B e antigen was associated with a sudden rise in serum transaminase levels and an exacerbation of hepatitis, a phenomenon that has also been reported in chronic hepatitis B patients who have responded well to interferon therapy. Therapy was well tolerated in all cases. Our results suggest that interferon treatment of patients with prolonged hepatitis B infection may prevent progression to chronicity. If confirmed by further study, they should trigger more vigilant screening for patients with raised serum transaminase levels and viral markers of hepatitis B infection.

Hepatitis A

Maynard, James E.

1976-01-01

Hepatitis A is a disease of worldwide distribution which occurs in endemic and epidemic form and is transmitted primarily by person-to-person contact through the fecal-oral route. Common source epidemics due to contamination of food are relatively common, and water-borne epidemics have been described less frequently. The presumed etiologic agent of hepatitis A has now been visualized by immune electron microscopic (IEM) techniques in early acute-illness-phase stools of humans with hepatitis A as well as in chimpanzees experimentally infected with material known to contain hepatitis A virus. In addition, several new serologic tests for the detection of antibody against hepatitis A virus have been described. These include complement fixation and immune adherence techniques. Current data suggest that hepatitis A is caused by a single viral agent lacking the morphologic heterogeneity of hepatitis B viral components and that there may be relative antigenic homogeneity between strains of virus recovered from various parts of the world. Serologic studies to date also indicate that hepatitis A virus is not a major contributing cause in post-transfusion hepatitis. ImagesFIG. 2 PMID:183390

A cross-sectional, seroepidemiological study was conducted to determine the prevalence and risk factors for hepatitis C virus (HCV) infection among veterans receiving health care from the VA. Among 274 evaluated outpatients, anti-HCV was found in 27 (9.9%). The prevalence of anti-HCV was 3.7% among 190 individuals who reported no illicit drug use compared to 24.7% among 81 subjects who had used drugs (P < 0.001). The prevalence of anti-HCV was 4.8% among 208 veterans who had never been incarcerated compared to 27.9% among 61 veterans who had been incarcerated (P < 0.001). A multivariate model found the following factors to be independently associated with anti-HCV; having used illicit drugs [odds ratio (OR) = 3.7, 95% CI 1.3-11.8; P = 0.001), having been incarcerated (OR = 4.4, 95% CI 1.7-10.9; P = 0.001), and a yearly income less than 10,000 US dollars (OR = 3.5, 95% CI 1.3-9.4; P = 0.002). Because HCV infection was most strongly associated with illicit drug use, incarceration, and low income, these risk factors should be utilized to develop screening strategies among VA patients.

Abstract Introduction and Aims Controlling behaviours are highly prevalent forms of non‐physical intimate partner violence (IPV). The prevalence of perpetrating controlling behaviours and technology‐facilitated abuse (TFA) was compared by men receiving substance use treatment in England (n = 223) and Brazil (n = 280). Factors associated with perpetrating these behaviours towards their current/most recent partner and their association with other types of IPV were explored. Design and Methods Secondary analysis from two cross‐sectional studies was performed. Data on socio‐demographic characteristics, infidelity, IPV perpetration and victimisation, adverse childhood experiences (ACE), attitudes towards gender relations and roles, substance use, depressive symptoms and anger expression were collected. Results Sixty‐four percent (143/223) and 33% (73/223) of participants in England and 65% (184/280) and 20% (57/280) in Brazil reported controlling behaviours and TFA, respectively, during their current/most recent relationship. Excluding IPV victimisation from the multivariate models; perpetrating controlling behaviours was associated with a higher number of ACE, higher anger expression (England) and severe physical IPV perpetration (Brazil), and perpetrating TFA was associated with younger age. Including both IPV victimisation and perpetration in the multivariate models; perpetrating controlling behaviour was associated with experiencing a higher number of ACE, higher anger expression (England), emotional IPV victimisation (England) and experiencing controlling behaviour from a partner (England). The perpetration of TFA was associated with younger age and experiencing TFA from a partner. Conclusions Technological progress provides opportunities for perpetrators to control and abuse their partners. Controlling behaviours and TFA should be addressed to reduce IPV perpetration by males in substance use treatment. [Gilchrist G, Canfield M,Radcliffe P, d

HIV and Hepatitis B Virus Coinfection: Approach to Management

2010-01-01

Objective To review diagnosis and treatment in patients with HIV and hepatitis B virus (HBV) coinfection. Methods Review of the literature in the context of a clinical case. Results All patients with HIV should be screened for the presence of coinfection with HBV. Following diagnosis with HBV infection, the level of HBV activity should be assessed with testing for HBeAg, HBV DNA, and potentially a biopsy for staging the degree of fibrosis present. Based on the results of this workup, a decision regarding the role of anti-hepatitis treatment should be made. According to the latest chronic hepatitis B and HIV treatment guidelines, coinfected patients who require treatment for chronic hepatitis B should be started on a regimen that is fully active against both HIV and HBV. A first-line regimen for coinfected patients is generally composed of tenofovir and emtricitabine, plus one other agent active against HIV. In coinfected patients, durable responses are rare, and therefore patients are usually required to remain on therapy indefinitely. Conclusion Intensification of surveillance techniques and education programs should be developed to help prevent transmission of infection and integrate coinfected patients into the health care system. Once engaged in care, coinfected patients should receive treatment for both HIV and chronic hepatitis B with the goal of a decrease in liver failure, cirrhosis, hepatocellular carcinoma, and chronic hepatitis B–related mortality.

The current standard treatment of chronic hepatitis C in Bosnia and Herzegovina consists of pegylated interferon alpha in combination with ribavirin. Interferon therapy has many psychiatric side effects, with depressive symptomatology being most prominent. The aim of the study was to establish the frequency and severity of depression in patients with chronic hepatitis C during two months of the aforementioned therapy. The overall sample consisted of 46 subjects, divided into three subgroups, aged 18 to 65. The study population consisted of subjects treated for chronic hepatitis C (n = 15), subjects infected but not treated for chronic hepatitis C (n = 15), and healthy controls (n = 16). The assessment and level of depression were based on the Structural clinical interview (SCID), Montgomery-Asberg Depression Rating Scale and Zung Self-Rating Depression Scale. The assessments were conducted before interferon therapy (on the day 0), after 4 and 8 weeks of therapy. Regarding its frequency, MADRS scoring showed that the number of depressed subjects receiving therapy increased after 8 weeks (46.7%). There was statistical significance between the subgroups after 4 and 8 weeks. Likewise, the ZUNG scale showed that the number of depressed subjects receiving therapy increased after 8 weeks (73.3%). There was statistical significance between the subgroups on the day 0, after 4 and 8 weeks. Depression was significantly more frequent in chronic hepatitis C subjects treated with interferon alpha in combination with ribavirin than in subjects in the group without therapy. Mild depression was most prevalent.

This study evaluated the immunogenicity, reactogenicity and safety of the combined Haemophilus influenzae type B Neisseria meningitidis serogroup C tetanus toxoid conjugate vaccine (Hib-MenC-TT) coadministered with diphtheria, tetanus, acellular pertussis hepatitis B-inactivated poliovirus (DTPa-HBV-IPV) as 2 primary and 1 booster doses at 3, 5 and 11 months of age. In this phase III open study (NCT00327184), 709 infants were randomized in 2 parallel groups (1:1) to receive either Hib-MenC-TT coadministered with DTPa-HBV-IPV or control vaccines (MenC-TT coadministered with DTPa-HBV-IPV/Hib). Serum bactericidal activity for MenC (rSBA-MenC) and antibody concentrations against polyribosylribitol phosphate from Hib (anti-PRP) and hepatitis B (anti-HBs) were measured at 1 month after dose 2, before booster and 1 month after booster dose. Solicited (local/general) and unsolicited symptoms were assessed up to 4 and 31 days, respectively, after each vaccination. Serious adverse events were recorded throughout the study. One month after dose 2, high percentages of infants in both groups had rSBA-MenC titers ≥ 8 (≥ 99.1%), anti-PRP concentrations ≥ 0.15 μg/mL (≥ 96.5%) and anti-HBs concentrations ≥ 10 mIU/mL (≥ 95.3%), which persisted up to the booster vaccination (≥ 94.5%, ≥ 86.1%, ≥ 94.2%) and increased again after the booster dose (100%, 100%, ≥ 99%). Exploratory analyses indicated that rSBA-MenC geometric mean titers were lower and anti-PRP geometric mean concentrations were higher in the infants vaccinated with Hib-MenC-TT compared with the control vaccines at all time points. The safety profiles of the coadministered vaccines were similar in both groups. The Hib-MenC-TT and DTPa-HBV-IPV vaccines are immunogenic with a clinically acceptable safety profile when coadministered as 2 primary doses during infancy and 1 booster dose at 11 months of age.

HIV prevalence among Chinese men who have sex with men has rapidly increased in recent years. In this randomized, controlled study, we tested the feasibility and efficacy of motivational interviewing to reduce high-risk sexual behaviors among this population in Changsha, China. Eighty men who have sex with men were randomly assigned to either the intervention group, in which participants received a three-session motivational interviewing intervention over 4 weeks, or the control group, in which participants received usual counseling from peer educators. High-risk behavior indicators and HIV knowledge level were evaluated at baseline and 3 months after the intervention. Motivational interviewing significantly improved consistent anal condom use. However, there was no significant change in consistent condom use for oral sex or in the number of sexual partners over time. HIV knowledge scores improved equally in both groups. This study demonstrated that an intervention using motivational interviewing is feasible and results in increased condom use during anal sex for Chinese men who have sex with men. However, further work must be done to increase the use of condoms during oral sexual encounters. © 2016 John Wiley & Sons Australia, Ltd.

Prostate cancer incidence and mortality are highest among African-American men, and coupled with the controversy around routine prostate cancer screening, reaching African-American men with interventions to help them make an informed decision about whether or not to be screened is critical. This study compares two approaches to delivering a church-based peer community health advisor intervention consisting of a series of four men's health workshops on informed decision-making for prostate cancer screening. In the men-only group, male community health advisors teach group workshops consisting only of men. In the health partner group, male-female pairs of community health advisors teach workshops in a mixed-gender format in which enrolled men are asked to invite a significant woman in their lives (e.g., wife/partner, sister, daughter, friend) with them to the workshops. Eighteen African-American churches were randomized to receive one of the two approaches, and 283 eligible men enrolled in the intervention. Main findings suggested that the workshops had an impact on stage of decision-making, and this increased significantly over time in the health partner group only. The intervention was highly rated by men in both groups, and these ratings increased over time, with some study group differences. Within-workshop study group differences favored the health partner group in some instances; however, men in the men-only groups reported greater increases in their ratings of trust in the workshops over time. The health partner intervention strategy appears to be promising for reaching men of color with health information.

"Médecins du Monde" healthcare centers receive individuals living in extremely precarious conditions for primary health care; 94% of these are foreigners. These medical consultations are an opportunity to discuss their serological status and to offer them screening tests. Two standardized questionnaires were implemented in all healthcare centers in 2000. The medical record covers knowledge of HIV and hepatitis B and C status. 41,033 consultations were given in 2012 in the 20 healthcare centers, for 23,181 patients. Only 29% of the patients knew their hepatitis status and 35% their HIV status. 42% of French patients were unaware of their HIV status compared to 67% of foreign patients. The lack of knowledge of foreign patients' HIV status was more frequent among men and in age classes<20 and>60 years of age. Patients from non-EU Europe, the Middle East, and Asia were significantly more likely to be unaware of their HIV status compared to people from Sub-Saharan Africa and Oceania/America. The rate of foreigners not having undergone screening remained stable, regardless of the duration of residence in France. These results highlight the need to develop specific prevention projects among immigrant populations in precarious situations. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Objectives To describe the epidemiology of people coinfected with hepatitis B virus (HBV) or hepatitis C virus (HCV) and HIV in San Francisco, the San Francisco Department of Public Health's Communicable Disease Control and Prevention Section and the HIV Epidemiology Section collaborated to link their registries. Methods In San Francisco, hepatitis reporting is primarily through passive laboratory-based surveillance, and HIV/AIDS reporting is primarily through laboratory-initiated active surveillance. We conducted the registry linkage in 2010 using a sequential algorithm. Results The registry match included 31,997 HBV-infected people who were reported starting in 1984; 10,121 HCV-infected people who were reported starting in 2001; and 34,551 HIV/AIDS cases reported beginning in 1981. Of the HBV and HCV cases, 6.3% and 12.6% were coinfected with HIV, respectively. The majority of cases were white males; however, black people were disproportionately affected. For more than 90% of the HBV/HIV cases, male-to-male sexual contact (men who have sex with men [MSM]) was the risk factor for HIV infection. Injection drug use was the most frequent risk factor for HIV infection among the HCV/HIV cases; however, 35.6% of the HCV/HIV coinfected males were MSM but not injection drug users. Conclusions By linking the two registries, we found new ways to foster collaborative work and expand our programmatic flexibility. This analysis identified particular populations at risk for coinfection, which can be used by viral hepatitis and HIV screening, prevention, and treatment programs to integrate, enhance, target, and prioritize prevention services and clinical care within the community to maximize health outcomes.

Copper is an essential trace element, but can become toxic when present in abundance. The severe effects of copper-metabolism imbalance are illustrated by the inherited disorders Wilson disease and Menkes disease. The Labrador retriever dog breed is a novel non-rodent model for copper-storage disorders carrying mutations in genes known to be involved in copper transport. Besides disease initiation and progression of copper accumulation, the molecular mechanisms and pathways involved in progression towards copper-associated chronic hepatitis still remain unclear. Using expression levels of targeted candidate genes as well as transcriptome micro-arrays in liver tissue of Labrador retrievers in different stages of copper-associated hepatitis, pathways involved in progression of the disease were studied. At the initial phase of increased hepatic copper levels, transcriptomic alterations in livers mainly revealed enrichment for cell adhesion, developmental, inflammatory, and cytoskeleton pathways. Upregulation of targeted MT1A and COMMD1 mRNA shows the liver’s first response to rising intrahepatic copper concentrations. In livers with copper-associated hepatitis mainly an activation of inflammatory pathways is detected. Once the hepatitis is in the chronic stage, transcriptional differences are found in cell adhesion adaptations and cytoskeleton remodelling. In view of the high similarities in copper-associated hepatopathies between men and dog extrapolation of these dog data into human biomedicine seems feasible. PMID:28459846

Autoimmune hepatitis is an unresolving, hepatocellular inflammation of unknown cause that is characterized by the presence of periportal hepatitis on histologic examination, tissue autoantibodies in serum, and hypergammaglobulinemia. By international consensus, the designation autoimmune hepatitis has replaced alternative terms for the condition. Three types of autoimmune hepatitis have been proposed based on immunoserologic findings. Type 1 autoimmune hepatitis is characterized by the presence of antinuclear antibodies (ANA) or smooth muscle antibodies (SMA) (or both) in serum. Seventy percent of patients with type 1 of autoimmune hepatitis are women. This type is the most common form and accounts for at least 80% of cases. Type 2 is characterized by the presence of antibodies to liver-kidney microsome type 1 (anti-LKM1) in serum. Patients with this type of autoimmune hepatitis are predominantly children. Type 3 autoimmune hepatitis is characterized by the presence of antibodies to soluble liver antigen (anti-SLA) in serum. There are no individual features that are pathognomonic of autoimmune hepatitis, and its diagnosis requires the confident exclusion of other conditions. The large majority of patients show satisfactory response to corticosteroid (usually prednisone or prednisolone) therapy. For the past 30 years it has been customary to add azathioprine as a "steroid sparing" agent to allow lower doses of steroids to be used and remission, once achieved, can be sustained in many patients with azathioprine alone after steroid withdrawal. Patients with autoimmune hepatitis who have decompensated during or after corticosteroid therapy are candidates for liver transplantation.

Dentists have a particular risk of acquiring viral hepatitis because of their close contact with blood and saliva during dental manipulations--especially as the majority of dentists do not use gloves during work and often have small cuts and abrasions on their hands. On the other hand personnel in the dentist's office offers several potential modes of parenteral and oral-intestinal transmission of hepatitis. In order to find out the risk of dentists exposing themselves to hepatitis-infection (especially hepatitis B-infection) we performed a questionnaire-study among practicing dentists all over Oberbayern. 858 replies were received after distribution of 1030 questionnaires (participation: 83.3%) and could by analyzed. 116 dentists had had a hepatitis during their professional work (13.5%). The frequency of hepatitis among the younger colleagues--who were practicing from 1 to 14 years--was about 5%. The number of hepatitis-infections increased continually up to 33% after 35--39 years of professional activity. In a second study blood samples were taken from 773 dentists and were tested for HB3Ag by radioimmunoassay. Of these 773 blood samples taken 25 (3.5%) were found to be antigen-positive. Compared to the general population the risk of infection is 6- to 30 times higher in dentists. The challenge of hepatitis-virus-infection can at present be met only-and at least in part-by scrupulous attention to prophylactic measures, such as using disposable gloves, needles and syringes and in autoclaving all non-disposable equipment. Besides dental personnel and patients should be screened at regular intervals for the presence of HBsAG.

How do men's magazines talk about penises?

Constructions of masculinity have shifted and changed but the central role of the penis has remained firm. Yet, despite the implications for sexual health, there has been very little research on discourses around penises. The messages men receive about their manhood is apparent in articles in men's magazines. We conducted a discursive analysis of the ways in which penises were discussed in four market leading UK titles: Loaded, Men's Health, GQ and Attitude. Two broad discourses were identified, termed Laddish and Medicalised, both of which create fear-ridden spaces where men are bombarded with unachievable masculine ideals and traumatic examples of mutilated members. We discuss how health psychologists could use the findings to communicate with men about their sexual health needs using this channel.

Randomised evaluations of resources to facilitate informed decisions about prostate cancer screening are rarely conducted. In this study, 421 men recruited from the community were randomly allocated to receive a leaflet (n = 140) or one of two resources meeting criteria for a decision-aid: a video (n = 141) or an evidence-based booklet, developed by the authors (n = 140). Men in all three groups demonstrated significant increases in knowledge scores from pre to post-test. Scores were significantly higher at post-test amongst those who had received our evidence-based booklet compared with men who received the leaflet or video (P < 0.001). Scores were significantly modified by men's preferences for decisional control (P = 0.002). Decisional conflict was significantly lower amongst men receiving the evidence-based booklet (P = 0.038). Men receiving the evidence-based booklet also were less likely to accept a recommendation by a GP to undergo prostate-specific-antigen (PSA) screening (P = 0.003). Men require detailed information about the pros and cons of PSA screening in order to make an informed decision. Resources are not equivalent in achieving these outcomes.

Hepatitis A and B viruses are threats to deployed military forces. The objective of this study was to determine the feasibility of concurrent vaccination against hepatitis A and B viruses. One hundred five healthy persons, 20 to 49 years of age and without serologic markers to hepatitis A or B viruses, were randomized to receive an inactivated hepatitis A vaccine (HEP A; 25 units in 0.5 mL), recombinant hepatitis B vaccine (HEP B; 10 micrograms in 1.0 mL), or both (HEP A & B) concurrently in separate arms. Vaccines were administered intramuscularly at 0, 1, and 6 months. Sera obtained at 1, 2, 6, 7, and 12 months after the first dose were tested for quantitative antibody to hepatitis A virus (anti-HAV) and antibody to hepatitis B surface antigen. Local reactions (e.g., pain) were reported by less than half of the volunteers and were similar at the site of HEP A, whether given alone or concurrently. However, more persons complained of pain (usually mild) at the HEP B site when HEP B was given concurrently with HEP A compared with HEP B alone (43% vs. 15%, 34% vs. 9%, and 42% vs. 15% for doses 1, 2, and 3, respectively; p < 0.05 for each dose). Among persons immunized with HEP A alone or HEP A & B, the proportion with > or = 10 mIU/mL anti-HAV was 83% in both groups 1 month after dose 1 and 100% at months 2, 7, and 12. The geometric mean concentrations of anti-HAV increased from 21 mIU/mL at month 1 to 2,649 and 2,312 mIU/mL in the HEP A and HEP A & B groups, respectively, at month 7. The response to HEP B was similar whether administered alone or concurrently. Antibody responses were similar in those receiving HEP A or HEP B concurrently or alone, but more subjects reported pain (usually mild) at the HEP B site after concurrent vaccination than after HEP B alone. Further work should be conducted to approve HEP A for patients younger than 2 years of age and to develop combined HEP A and HEP B vaccines in the United States.

2015-03-01

The only established therapy for chronic viral delta hepatitis, the most severe form of viral hepatitis is treatment with pegylated-interferon α (Peg IFN α). In this study, we aimed to determine the efficacy of pegylated-interferon α 2a (Peg-IFN α 2a) and 2b (Peg IFN α 2b) in the treatment of patients infected with chronic delta hepatitis virus. The sample size was based on available patients potentially to be recruited. Data of 63 patients receiving either Peg IFN alpha 2a or Peg IFN alpha 2b were retrospectively assessed in the present cohort study performed in Turkey. Of 56 patients completed the study, 41 received Peg IFN α 2a and 15 received Peg IFN α 2b for 12 months. Patients were evaluated for biochemical and virological responses at the end of given treatment and six months after the treatment. Stage of fibrosis was found high in both groups (85.4% vs. 86.7%), while cirrhosis was higher in the group of Peg IFN α 2b (53.3% vs. 34.1%). At the end of treatment, either hepatitis delta virus RNA (HDV RNA) alone or both HDV RNA and hepatitis b virus DNA (HBV DNA) had negative results in 32% of patients. Although HDV RNA negativity was sustained in 30.3% of patients, negativity of both HDV RNA and HBV DNA was decreased to 19.6% six months after completion of the treatment. HBV DNA became positive in one third of patients with response at six months after completion of the treatment (10.7% of all patients). HDV RNA negativity at month six was found as a predictor of positive response. No significant difference was found between Peg IFN α 2a and Peg IFN α 2b for virological response rate. Treatment with Peg IFN α achieved a sustained negativity of HDV RNA in about one third of patients. Duration of Peg IFN α therapy might be prolonged to at least 24 months or more to prevent the occurrence of Hepatitis B virus (HBV) relapse encountered six months after completion of the treatment.

The Advisory Committee on Immunization Practices recommends that susceptible people traveling to developing countries receive hepatitis A vaccine or immune globulin prior to departure. Until 2009, the recommendations did not address non-traveling family members or other close contacts of international adoptees. We report an outbreak of hepatitis A in 2008 that occurred in Maine. Eight members of an extended family developed hepatitis A following the arrival of an asymptomatic infant from Ethiopia who was brought to the United States by an adoption agency. Two children in the family attended an elementary school where five additional cases of hepatitis A were subsequently identified. Only three (1%) of 208 students at the school had previously been immunized against hepatitis A. This outbreak highlights the need to immunize household members and other close contacts of families adopting children from countries where hepatitis A is endemic, as well as all children at one year of age.

Female injection drug users (IDUs) may report differences in injection behaviours that put them at greater risk for hepatitis C virus (HCV). Few studies have examined these in association with HCV incidence. Longitudinal data from a cohort of 417 HCV-uninfected IDU aged 30 or younger were analysed. Cox proportional hazards was used to model female sex as a predictor of new HCV infection. General estimating equation (GEE) analysis was used to model female sex as a predictor of HCV-associated risk behaviour prospectively. Women were significantly more likely than men to become infected with HCV during study follow-up (HR 1.4, p<0.05), and were also more likely than men to report high-risk injecting behaviours, especially in the context of sexual and injecting relationships. Sex differences in injecting behaviours appeared to explain the relationship between sex and HCV infection. Young women's riskier injection practices lead to their higher rates of HCV infection. Further study on the impact of intimate partnership on women's risk behaviour is warranted. Published by the BMJ Publishing Group Limited.

Acute hepatitis C (AHCV) provides a diagnostic challenge with diverse clinical presentations. This study was aimed to examine the clinical and demographic features as well as outcomes in AHCV patients identified from inpatient and outpatient hospital settings. Patients with suspected AHCV were recruited from Philadelphia VA Medical Center, Hospital of University of Pennsylvania and Brooklyn VA Medical Center between 2000 and 2010. AHCV was diagnosed by acute serum alanine aminotransferase elevation with anti-hepatitis C virus (HCV) seroconversion, HCV-RNA fluctuations above 1 log, and/or recent high-risk exposure without prior HCV infection, excluding those with human immunodeficiency virus infection. Clinical and therapeutic outcomes were monitored for at least 6 months. A total of 40 AHCV patients were enrolled with a median follow-up of 129 weeks. They were mostly men (68%) and whites (73%) with median age of 43 years, diverse risk factors (33% injection drugs, 20% health care-associated, 3% sexual, and 45% unknown), and wide variations in peak alanine aminotransferase (143 to 3435 U/L) and total bilirubin levels (0.4 to 19.3 mg/dL). Viremia resolved spontaneously in 23% and persisted without therapy in 27%, whereas 50% received interferon α-based therapy with 90% cure (18/20). Distinct clinical scenarios included: (1) wide viremic fluctuations >1 log (65%) and intermittent HCV-RNA negativity; (2) autoantibodies (25% antinuclear antibodies, 69% antismooth muscle antibodies) or autoimmune features; (3) delayed spontaneous viral clearance in 2 patients; (4) rapid cirrhosis progression in 2 patients. AHCV is a heterogenous disease that requires careful monitoring. The lack of apparent risk factor in high proportion of patients and its diverse presentations warrant diagnostic vigilance.

Purpose We know little about the prevalence of sexting behavior among young men who have sex with men (YMSM) or its association with their sexual behaviors. Methods To address these gaps, we used data from an online study examining the partner-seeking behaviors of single YMSM (N=1,502; ages 18–24) in the U.S. Most participants (87.5%) reported sexting, with 75.7% of the sample reporting having sent and received a sext. Results Sexting was more frequent among sexually-active YMSM, with YMSM who had sent and received a sext being more likely to report insertive anal intercourse, with and without condoms, than those who had not sexted. We found no association between sexting and receptive anal intercourse. Conclusions Our findings suggest that sexting may vary by YMSM’s sexual roles. We discuss our findings with attention to their implications for sexual health promotion. PMID:24361235

To compare the immune responses of the 10 μg and 20 μg doses of CHO hepatitis B vaccine on adults. Adults aged 18-45 years who gave a history of never having received hepatitis B vaccine and lacked serologic evidence of infection to hepatitis B virus (HBV) infection or previous vaccination were enrolled into the study. A total of 642 eligible participants were randomized to receive 3 doses of either the 10 μg or the 20 μg formulation of CHO hepatitis B vaccine in a 0-1-6 month schedule. Each study subject had a serologic specimen collected one month following the third vaccine dose that was tested for markers of HBV infection and anti-HBs by Abbott I2000. Persons who tested negative for anti-HBs negative persons were tested for HBV DNA. Logistic regression was used to identify factors associated with antibody response. Among the participants, 153 subjects had their lymphocytes cultivated and tested for cytokine production. Enzyme-linked immunospot (ELISPOT) was used to test spot numbers of IL-4, IFN-γ which produced by lymphocyte. The anti-HBs seroconversion rate was 88.8% (95% CI: 85.4-92.2%) and 95.3% (95% CI: 93.0-97.6%), respectively in 10 μg and 20 μg group. Geometric mean titers (GMT) were 173.42 mIU/ml and 585.51 mIU/ml, respectively in 10 μg and 20 μg groups. Multivariate analysis demonstrated that diabetes, spouse is hepatitis B virus infector, older age and receipt of the 10 μg dose were all negatively associated with antibody response (P<.05). Cellular immunity results showed: IL-4 immunity spot numbers in 20 μg group was higher than 10 μg group. With anti-HBs increased, the IL-4 immunity spot numbers increased significantly which had significant positive correlation (Spearman coefficient=0.538, P<0.0001). IFN-γ spot numbers had no statistical significant between the two groups. The humoral immunity and cytokines response among the group that received the 20 μg CHO hepatitis B vaccine dose was superior compared to the group that received

The purposes of this study were to determine whether exposure of the vestigial male breast to ionizing radiation is associated with an increase in risk of breast cancer and, if so, to determine whether the apparent effects on risk in men are similar to those reported for women. A population-based case-control study of breast cancer in men was conducted in 10 geographic areas of the United States. Information on possible prior exposure to ionizing radiation, and on other potential risk factors for breast cancer, was obtained from personal interviews of 227 cases and 300 controls who were recruited from October 1983 to September 1986. Evidence from this study that ionizing radiation can cause breast cancer in men includes: a modest trend of increasing risk with frequency of chest X-rays; an increase in risk in men with three or more radiographic examinations, especially if received prior to 1963; and an increase in risk in men who received X-ray treatments to the chest and adjacent body areas. Risk was increased only from 20 to 35 years after initial exposure from either radiographic examinations or X-ray treatments, and declined after three to four decades since last exposure, suggesting a wave of increased risk of finite duration following exposure. The doses of radiation received could not be estimated precisely, but those from diagnostic procedures were likely similar to those received by prepubertal females in prior studies, and the results of those and the present investigation are compatible. The carcinogenic effects of ionizing radiation may be similar in the male and prepubertal female breast.

Hepatic encephalopathy has been listed as a differential for llamas displaying neurologic signs, but it has not been histopathologically described. This report details the neurologic histopathologic findings associated with 3 cases of hepatic lipidosis with concurrent neurologic signs and compares them to 3 cases of hepatic lipidosis in the absence of neurologic signs and 3 cases without hepatic lipidosis. Brain from all 3 llamas displaying neurologic signs contained Alzheimer type II cells, which were not detected in either subset of llamas without neurologic signs. Astrocytic immunohistochemical staining intensity for glial fibrillary acid protein was decreased in llamas with neurologic signs as compared to 2 of 3 llamas with hepatic lipidosis and without neurologic signs and to 2 of 3 llamas without hepatic lipidosis. Immunohistochemical staining for S100 did not vary between groups. These findings suggest that hepatic encephalopathy may be associated with hepatic lipidosis in llamas.

Hepatitis viral infection is hyperendemic in Egypt, western Asia and Africa. However, little is known about the status of hepatitis viruses among rural Egyptian children. Therefore, this study sought to examine the prevalence and characteristics of hepatitis viruses among symptomatic Egyptian children. Serological and molecular analyses of hepatitis viral infection were conducted in 33 children hospitalised at Mansoura University with symptomatic hepatic dysfunction (mean ± standard deviation age, 9.7±3.4 years; alanine aminotransferase level, 130±68 IU/ml). Eleven children (33%) were positive for anti-haemagglutination-IgM and were diagnosed with acute hepatitis A. Hepatitis B surface antigen (HBsAg) and anti‑hepatitis C virus (HCV) were detected in 9 (27%) and 7 (21%) children, respectively, indicating acute-on-chronic infection with hepatitis viruses. None of the children was positive for anti‑hepatitis B core antigen-IgM. Phylogenetic analysis confirmed that all HBVs belonged to genotype D (subgenotype D1) and that HCV belonged to genotypes 4a and 1g. HBV-DNA was detected in 9 children (27%) in the pre-S/S region and in 16 children (48%) in the core promoter/precore region. The Y134F amino acid mutation in the 'α' determinant region was detected in all of the patients. The A1762T/G1764A double mutation, and the T1846A and G1896A single mutations were common in children with occult HBV infection. In conclusion, hepatitis viral infection, including acute-on-chronic infection with HCV and HBV, is common in Egyptian children hospitalised with acute hepatitis.

The urea cycle is a rate-limiting step for amino acid nitrogen elimination. The rate of urea synthesis is a true indicator of whole-body protein catabolism. Testosterone reduces protein and nitrogen loss. The effect of testosterone on hepatic urea synthesis in humans has not been studied. To determine whether testosterone reduces hepatic urea production. An open-label study. Eight hypogonadal men were studied at baseline, and after two weeks of transdermal testosterone replacement (Testogel, 100 mg/day). The rate of hepatic urea synthesis was measured by the urea turnover technique using stable isotope methodology, with 15 N 2 -urea as tracer. Whole-body leucine turnover was measured, from which leucine rate of appearance (LRa), an index of protein breakdown and leucine oxidation (Lox), a measure of irreversible protein loss, were calculated. Testosterone administration significantly reduced the rate of hepatic urea production (from 544.4 ± 71.8 to 431.7 ± 68.3 µmol/min; P  < 0.01), which was paralleled by a significant reduction in serum urea concentration. Testosterone treatment significantly reduced net protein loss, as measured by percent Lox/LRa, by 19.3 ± 5.8% ( P  < 0.05). There was a positive association between Lox and hepatic urea production at baseline ( r 2  = 0.60, P  < 0.05) and after testosterone administration ( r 2  = 0.59, P  < 0.05). Testosterone replacement reduces protein loss and hepatic urea synthesis. We conclude that testosterone regulates whole-body protein metabolism by suppressing the urea cycle. © 2017 European Society of Endocrinology.

The liver is the primary site of metastases in most uveal melanoma patients. We retrospectively investigated intraarterial chemotherapy (IAC) as treatment for patients with hepatic melanoma metastases.Twenty-three patients (18 with uveal melanoma) received fotemustine (14 patients, 61.9%) or carboplatin (9 patients, 31.1%) via hepatic IAC delivery. The catheter was introduced through percutaneous access to the femoral artery with drugs delivered directly to the hepatic artery, and was removed at the end of each treatment cycle. A total of 3 cycles was planned, repeated every 21 days. However, patients with a clinical response could receive more than 3 cycles, provided that the toxic effects were acceptable.IAC was well tolerated and no catheter-related complications or grade 4 toxicities were reported. Considering only uveal melanoma patients, the overall response rate and disease control rate was 16.7% and 38.9%, respectively. Median time to progression was 6.2 months (95% CI 3.7-10.5) and median overall survival was 21 months (95% CI 8-39).IAC is well tolerated and is a valid choice for patients with a poor prognosis since median survival rates are among the longest reported.

Overdoses of acetaminophen (APAP), a famous and widely used drug, may have hepatotoxic effects. Nanoscience is a novel scientific discipline that provides specific tools for medical science problems including using nano trace elements in hepatic diseases. Our study aimed to assess the hepatoprotective role of selenium nanoparticles (Nano-Se) against APAP-induced hepatic injury. Twenty-four male rats were classified into three equal groups: a control group that received 0.9 % NaCl, an APAP-treated group (oral administration), and a group treated with Nano-Se (10-20 nm, intraperitoneal (i.p.) injection) and APAP (oral administration). APAP overdose induced significant elevations in liver function biomarkers, hepatic lipid peroxidation, hepatic catalase, and superoxide dismutase (SOD), decreased the reduced glutathione (GSH) content and glutathione reductase (GR) activity, and stimulated significant DNA damage in hepatocytes, compared to control rats. Nano-Se administration improved the hepatic antioxidant protection mechanism and decreased cellular sensitivity to DNA fragmentation. Nano-Se exhibits a protective effect against APAP-induced hepatotoxicity through improved liver function and oxidative stress mediated by catalase, SOD, and GSH and decreases hepatic DNA fragmentation, a hepatic biomarker of cell death. Nano-Se could be a novel hepatoprotective strategy to inhibit oxidative stress.

Inclusion of hepatitis B vaccine in the Universal Programme of Immunization of all Asian and African countries is hampered by the economic burden on the health budget because of the cost of hepatitis B vaccines. Here we evaluated the immunogenicity, safety, efficacy, and the persistence of antibody to hepatitis B surface antigen (anti-HBs) titers of a new and a low cost recombinant hepatitis B vaccine GeneVac B, with 2 different dosages in healthy adolescents in India. GeneVac-B, a recombinant hepatitis B vaccine (Serum Institute of India, Pune, India), was administered in 10 or 20 microg dose intramuscularly to 2 groups of 100 healthy school-going adolescents at 0-, 1-, and 6-month intervals, who were followed up for 1 year. Group I received 20 mug doses whereas Group II received 10 mug doses. Blood samples were collected 1 month after each dose and 1 year after the third dose. The anti-HBs titers were assayed using commercially available kits to assess the immunogenicity of the 2 dosage schedules. Safety studies were also carried out. The geometric mean titer value of the anti-HBs titer 1 month after the third dose was 2629 (mlU/mL) in Group I and 1373 mlU/mL for Group II subjects. One year after the third dose, the persistence of anti-HBs in those who had received 20 mug was 2262 mlU/mL whereas it was 1039 mlU/mL in the group receiving 10 microg doses. All the subjects in both the groups were seroprotected at 1 year after vaccination. None of the vaccinees exhibited serious adverse reactions throughout the study period. The study demonstrated the immunogenicity of the recombinant hepatitis B vaccine, and confirms that the 0.5 mL (10 microg) dose of GeneVac B can be administered with satisfactory safety and immunogenicity to adolescents up to 19 years of age, reducing the cost to less than U.S. $1.00 per dose making it acceptable for the Universal Programme of Immunization of developing and under developed countries.

The epidemiology of hepatitis B virus (HBV) infection in North America may be changing as a result of immigration from endemic countries. The purpose of this study was to determine the prevalence of HBV genotypes, precore (PC) and core promoter (CP) variants, and the proportion of patients meeting treatment criteria for HBV. A cross-sectional study of consecutive HBV patients attending a Canadian tertiary liver center was conducted. HBV DNA was quantified by polymerase chain reaction assay. HBV genotypes and variants were determined using a line probe assay. Two hundred and seventy-two patients were enrolled; 200 were not receiving treatment at enrollment, of whom 116 were men and 84 women with a mean age 42+/-14 years. Among this group, 177 (88%) patients were Asian and 19 (10%) were Caucasian and 69 (35%) patients were hepatitis B e antigen (HBeAg) positive. Genotypes B and C were found in 42% and 50% untreated patients, respectively; while CP and PC were detected in 52% and 43% patients, respectively. Approximately 20% patients not receiving treatment (29% HBeAg positive, 14% HBeAg negative) met AASLD guidelines for antiviral therapy. If lower cutoff values for alanine aminotransferase and HBV DNA levels were used, 49% patients would qualify for treatment. The vast majority of patients at a Canadian tertiary referral center were Asian. Virological and clinical characteristics of these patients reflect their country of origin. Our findings highlight the need to monitor the changing patterns of HBV infection in countries with large immigrant populations.

Comparison of the effects of enteral feeding with continuous and intermittent parenteral nutrition on hepatic triglyceride secretion in human beings

Plasma triglyceride turnover was measured during steady-state conditions in 22 postoperative patients. Nine had received nutritional support with an enteral regimen, seven had received an equivalent regimen as continuous parenteral nutrition, and six received the same parenteral regimen as a cyclical infusion. After 5 days of nutritional support, each patient received an intravenous bolus of tritiated glycerol. Plasma radiolabeled triglyceride content was measured during the subsequent 24 hours. The data were analyzed by means of a simple deterministic model of plasma triglyceride kinetics and compared with the results obtained by stochastic analysis. The rates of hepatic triglyceride secretion obtained bymore » deterministic analysis were higher than those obtained by the stochastic approach. However, the mode of delivery of the nutritional regimen did not affect the rate of hepatic triglyceride secretion regardless of the method of analysis. The results suggest that neither complete nutritional bypass of the gastrointestinal tract nor interruption of parenteral nutrition in an attempt to mimic normal eating has any effect on hepatic triglyceride secretion. Any beneficial effect that enteral feeding or cyclical parenteral nutrition may have on liver dysfunction associated with standard parenteral nutrition appears to be unrelated to changes in hepatic triglyceride secretion.« less

The systemic therapies available for the management of Psoriasis (PsO) patients who cannot be treated with more conservative options, such as topical agents and/or phototherapy, with the exception of acitretin, can worsen or reactivate a chronic infection. Therefore, before administering immunosuppressive therapies with either conventional disease-modifying drugs (cDMARDs) or biological ones (bDMARDs) it is mandatory to screen patients for some infections, including hepatitis B virus (HBV) and hepatitis C virus (HCV). In particular, the patients eligible to receive an immunosuppressive drug must be screened for the following markers: antibody to hepatitis B core, antibody to hepatitis B surface antigen (anti-HBsAg), HBsAg, and antibody to HCV (anti-HCV). In case HBV or HCV infection is diagnosed, a close collaboration with a consultant hepatologist is needed before and during an immunosuppressive therapy. Concerning therapy with immunosuppressive drugs in PsO patients with HBV or HCV infection, data exist mainly for cyclosporine a (CyA) or bDMARDs (etanercept, adalimumab, infliximab, ustekinumab). The natural history of HBV and HCV infection differs significantly as well as the effect of immunosuppression on the aforementioned infectious diseases. As a rule, in the case of active HBV infection, systemic immunosuppressive antipsoriatic therapies must be deferred until the infection is controlled with an adequate antiviral treatment. Inactive carriers need to receive antiviral prophylaxis 2-4 wk before starting immunosuppressive therapy, to be continued after 6-12 mo from its suspension. Due to the risk of HBV reactivation, these patients should be monitored monthly for the first 3 mo and then every 3 mo for HBV DNA load together with transaminases levels. Concerning the patients who are occult HBV carriers, the risk of HBV reactivation is very low. Therefore, these patients generally do not need antiviral prophylaxis and the sera HBsAg and transaminases dosing can

A questionnaire was mailed to 1217 dentists whose names appear in the Dentist Register of 1987 in order to assess their awareness and acceptance of hepatitis B vaccine and their pattern of glove usage. Almost all the respondents (99.6%) were aware of the availability of the hepatitis B vaccine yet only 44.8% have received the vaccine. This is in spite of the fact that the majority (61.2%) of the vaccine non-acceptors have no reservations concerning the vaccine. About 71% and 63% of the vaccine-acceptors and non-acceptors respectively believed that the risk of their contracting hepatitis B was high or very high. About 22% of the vaccine non-acceptors never used gloves when treating patients as compared to 9% among vaccine acceptors. Overall, about 78% of the respondents have experienced needleprick injuries in the 3 years preceding the survey.

Family planning programs have made vast progress in many regions of sub-Saharan Africa in the last decade, but francophone West Africa is still lagging behind. More emphasis on male engagement might result in better outcomes, especially in countries with strong patriarchal societies. Few studies in francophone West Africa have examined attitudes of male involvement in family planning from the perspective of men themselves, yet this evidence is necessary for development of successful family planning projects that include men. This qualitative study, conducted in 2016, explored attitudes of 72 married men ages 18-54 through 6 focus groups in the capital of Togo, Lomé. Participants included professional workers as well as skilled and unskilled workers. Results indicate that men have specific views on family planning based on their knowledge and understanding of how and why women might use contraception. While some men did have reservations, both founded and not, there was an overwhelmingly positive response to discussing family planning and being engaged with related decisions and services. Four key findings from the analyses of focus group responses were: (1) socioeconomic motivations drive men's interest in family planning; (2) men strongly disapprove of unilateral decisions by women to use family planning; (3) misconceptions surrounding modern methods can hinder support for family planning; and (4) limited method choice for men, insufficient venues to receive services, and few messages that target men create barriers for male engagement in family planning. Future attempts to engage men in family planning programs should pay specific attention to men's concerns, misconceptions, and their roles in family decision making. Interventions should educate men on the socioeconomic and health benefits of family planning while explaining the possible side effects and dispelling myths. To help build trust and facilitate open communication, family planning programs that

Chinese immigrants to North America have substantially higher rates of chronic hepatitis B infection than the general population. One area for strategic development in the field of health education is the design and evaluation of English-as-a-Second language (ESL) curricula. The theoretical perspective of the Health Behavior Framework, results from a community-based survey of Chinese Canadian immigrants with limited English proficiency, and findings from focus groups of ESL instructors as well as Chinese ESL students were used to develop a hepatitis B ESL educational module. This research was conducted in Vancouver, BC. Survey data showed that less than three-fifths of the respondents had been tested for hepatitis B, and documented some important hepatitis B knowledge deficits. Further, only about one-quarter had ever received a physician recommendation for hepatitis B serologic testing. The ESL curriculum aims to both promote hepatitis B testing and improve knowledge, and includes seven different ESL exercises: Warm-up, vocabulary cards, information-gap, video, jigsaw, guided discussion, and problem/advice cards. Our quantitative and qualitative methods for curriculum development could be replicated for other health education topics and in other limited English speaking populations.

In Denmark, universal screening of pregnant women for hepatitis B has been in place since November 2005, with the first two years as a trial period with enhanced surveillance. It is unknown what the change to universal screening without enhanced surveillance has meant for vaccination coverage among children born to hepatitis B surface antigen (HBsAg)-positive mothers and what risk factors exist for incomplete vaccination. This retrospective cohort study included 699 children of mothers positive for HBsAg. Information on vaccination and risk factors was collected from central registers. In total, 93% (651/699) of the children were vaccinated within 48 hours of birth, with considerable variation between birthplaces. Only 64% (306/475) of the children had received all four vaccinations through their general practitioner (GP) at the age of two years, and 10% (47/475) of the children had received no hepatitis B vaccinations at all. Enhanced surveillance was correlated positively with coverage of birth vaccination but not with coverage at the GP. No or few prenatal examinations were a risk factor for incomplete vaccination at the GP. Maternity wards and GPs are encouraged to revise their vaccination procedures and routines for pregnant women, mothers with chronic HBV infection and their children.

Animal models of total hepatic ischemia (THI) and reperfusion injury are restricted by concomitant splanchnic congestion. This study was performed to determine the requirement suitable for an extracorporeal portosystemic shunt (PSS) to maintain the intestinal integrity in a rat model of THI. Using a polyethylene tube (0.86 or 1 mm i.d.), PSS was placed between the mesenteric and jugular veins. Comparison was done between THI models with or without PSS and a partial ischemia model with hepatectomy of the nonischemic lobes. Well-tolerated hepatic ischemic period, portal pressure after 10 min of hepatic ischemia, portal endotoxin levels at 1 h after reperfusion, histological features of the small bowel just before reperfusion, and local jejunal and ileal blood hemoglobin oxygen saturation index (ISO2) were compared among the models. Animals without PSS poorly tolerated 30 min of THI. Animals receiving THI with PSS or partial hepatic ischemia tolerated a longer ischemic period (60 min) with a significantly higher small bowel ISO2, lower portal pressure and endotoxin levels (P < 0.01), and less histological damage of the small bowel when compared to those receiving THI without PSS. Portal endotoxin levels after THI with PSS using a 1-mm i.d. tube as well as partial hepatic ischemia were significantly lower than those after THI with PSS using a 0.86-mm i.d. tube. THI with PSS using a 1-mm i.d. tube was strikingly similar to partial hepatic ischemia in the pathophysiological profile during hepatic ischemia. PSS with a tube 1 mm or more in inner diameter offers pathophysiological advantages in experiments on THI and reperfusion. Copyright 1998 Academic Press.

Hepatic metastases from medullary thyroid carcinoma (MTC) may impair quality of life by hypercalcitonemia-associated diarrhea and pain. In this prospective study, the effect of selective arterial chemoembolization (SACE) was evaluated. Eleven patients with hepatic metastases from MTC received 1 to 9 courses of SACE using epirubicine. Symptomatic, biochemical, and morphologic responses on SACE were recorded. Symptomatic response was observed in all symptomatic patients. However, biochemical and radiologic response occurred only in 6 patients. Liver function was not affected by SACE. One patient with unexpected concurrent pheochromocytoma metastases died after the first course. Development of side effects in the course was observed in 8 patients but were only World Health Organization grade 1. Patients' satisfaction with SACE was excellent. Long-term follow-up found 7 patients alive (1-72 months). Three patients died with tumor 6, 12, and 24 months after SACE, respectively. SACE provided good symptom palliation for the majority of patients with hepatic metastases from MTC. However, transient remission or stabilization of hepatic metastases resulted in only 60%. Further studies using a randomized protocol are required.

The authors report the case of a 36-year-old man who was hospitalized for portal hypertension. The patient had been receiving 200 millions units of vitamin A for ten years duration as treatment of psoriasis. There were no extrahepatic signs of hypervitaminosis A and the serum concentration of vitamin A was low. Microscopic examination of a liver specimen showed: a) spontaneous fluorescence due to vitamin A accumulation in sinusoidal cells; b) portal, periportal and perisinusoidal fibrosis; c) hyperplasia and hypertrophy of Ito cells. Hepatic vitamin A concentration was markedly increased. Hemodynamic study showed increased wedged hepatic venous pressure. Low serum concentration of retinol binding protein, which could be due to severe denutrition, explained the low serum vitamin A. This case report emphasizes that severe hepatic injury due to chronic hypervitaminosis A may be observed in the absence of extrahepatic signs of vitamin A intoxication and increase in serum vitamin A concentration. In such cases, histologic examination of a liver specimen and determination of hepatic vitamin A concentration are the only means of diagnosis.

Hepatitis B-related knowledge and vaccination in association with discrimination against Hepatitis B in rural China

Hepatitis B virus (HBV) remains a challenging public-health issue in China. Hepatitis B carriers and patients suffer not only physically but also experience strong discrimination and stigma. China's rural population is 629 million. Thus, there is a great need to understand the situation surrounding HBV-related discrimination in everyday life in rural China. We studied 6,538 participants (≥18 y old) from 42 villages across 7 provinces (districts). Many studies have addressed discrimination against those with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). However, few studies have addressed HBV-related discrimination. We found that the fear of HBV infection, not lack of knowledge about it, predominantly leads to HBV-related discrimination (although limited knowledge is also a cause). Notably, receiving the HBV vaccination contributes to reduced discrimination. In addition, the existence of fewer misunderstandings about false HBV transmission routes plays a more important role in discrimination than does understanding of true HBV transmission routes. Therefore, to reduce HBV-related discrimination, policy makers should consider eliminating HBV-related fear, strengthening adult HBV immunization programs, developing large-scale education dissemination about HBV transmission routes and non-transmission routes, and paying greater attention to target populations.

We know little about the prevalence of sexting behavior among young men who have sex with men (YMSM) or its association with their sexual behaviors. To address these gaps, we used data from an online study examining the partner-seeking behaviors of single YMSM (N = 1,502; ages 18-24 years) in the United States. Most participants (87.5%) reported sexting, with 75.7% of the sample reporting having sent and received a sext. Sexting was more frequent among sexually active YMSM, with YMSM who had sent and received a sext being more likely to report insertive anal intercourse, with and without condoms, than those who had not sexted. We found no association between sexting and receptive anal intercourse. Our findings suggest that sexting may vary by YMSM's sexual roles. We discuss our findings with attention to their implications for sexual health promotion. Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

The incidence of hepatitis A infection in the United States has decreased dramatically in recent years because of childhood immunization programs. A decision analysis of the cost-effectiveness of hepatitis A vaccination for adults with hepatitis C was conducted. No vaccination strategy is cost-effective for adults with hepatitis C using the recent lower anticipated hepatitis A incidence, private sector costs, and a cost-effectiveness criterion of $100,000/QALY. Vaccination is cost-effective only for individuals who have cleared the hepatitis C virus when Department of Veterans Affairs costs are used. The recommendation to vaccinate adults with hepatitis C against hepatitis A should be reconsidered. Published by Elsevier Ltd.

Hepatitis E virus and fulminant hepatitis--a virus or host-specific pathology?

PubMed

Smith, Donald B; Simmonds, Peter

2015-04-01

Fulminant hepatitis is a rare outcome of infection with hepatitis E virus. Several recent reports suggest that virus variation is an important determinant of disease progression. To critically examine the evidence that virus-specific factors underlie the development of fulminant hepatitis following hepatitis E virus infection. Published sequence information of hepatitis E virus isolates from patients with and without fulminant hepatitis was collected and analysed using statistical tests to identify associations between virus polymorphisms and disease outcome. Fulminant hepatitis has been reported following infection with all four hepatitis E virus genotypes that infect humans comprising multiple phylogenetic lineages within genotypes 1, 3 and 4. Analysis of virus sequences from individuals infected by a common source did not detect any common substitutions associated with progression to fulminant hepatitis. Re-analysis of previously reported associations between virus substitutions and fulminant hepatitis suggests that these were probably the result of sampling biases. Host-specific factors rather than virus genotype, variants or specific substitutions appear to be responsible for the development of fulminant hepatitis. © 2014 The Authors.

Antiretroviral preexposure prophylaxis has been shown to reduce the risk of human immunodeficiency virus type 1 (HIV-1) infection in some studies, but conflicting results have been reported among studies, probably due to challenges of adherence to a daily regimen. We conducted a double-blind, randomized trial of antiretroviral therapy for preexposure HIV-1 prophylaxis among men who have unprotected anal sex with men. Participants were randomly assigned to take a combination of tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) or placebo before and after sexual activity. All participants received risk-reduction counseling and condoms and were regularly tested for HIV-1 and HIV-2 and other sexually transmitted infections. Of the 414 participants who underwent randomization, 400 who did not have HIV infection were enrolled (199 in the TDF-FTC group and 201 in the placebo group). All participants were followed for a median of 9.3 months (interquartile range, 4.9 to 20.6). A total of 16 HIV-1 infections occurred during follow-up, 2 in the TDF-FTC group (incidence, 0.91 per 100 person-years) and 14 in the placebo group (incidence, 6.60 per 100 person-years), a relative reduction in the TDF-FTC group of 86% (95% confidence interval, 40 to 98; P=0.002). Participants took a median of 15 pills of TDF-FTC or placebo per month (P=0.57). The rates of serious adverse events were similar in the two study groups. In the TDF-FTC group, as compared with the placebo group, there were higher rates of gastrointestinal adverse events (14% vs. 5%, P=0.002) and renal adverse events (18% vs. 10%, P=0.03). The use of TDF-FTC before and after sexual activity provided protection against HIV-1 infection in men who have sex with men. The treatment was associated with increased rates of gastrointestinal and renal adverse events.

Paraphenylene diamine (PPD) ingestion is manifesting as one of the more common ways of committing suicide in Southern Punjab, Pakistan, especially Bahawalpur. PPD is an ingredient of a compound commonly known "Kala Pathar" which means "Black Stone" in Urdu. It is readily available in the market at low cost and is used to dye hair and fur. Its intoxication inhibits cellular oxidation and affects the muscles causing rhabdomyolysis. This leads to myoglobinuria followed by renal failure and edema of face and throat resulting in respiratory difficulty. Very little is known about the impact of PPD intoxication on liver tissue. The purpose of the study was to find out the frequency of acute hepatitis following PPD intoxication. We reviewed the medical records of 109 patients with PPD intoxication admitted to Medical Unit-2, Bahawalpur Victoria Hospital from January 1, 2015, to June 30, 2015, in a descriptive, cross-sectional study. We noted the frequency of acute hepatitis and other complications, and we recorded the demographic features, clinical features, and outcomes of these patients. Our study included 32 men (29%) and 77 women (71%). The mean age was 22 ± 3.4 years, and most patients were young women aged 15 to 24 years. Suicidal ingestion was the leading cause of admission for 101 patients (93%). The most common clinical presentation was cervicofacial edema (95%), throat pain (88%), dysphonia (95%), cola-colored urine (100%), and oliguria (95%). Rhabdomyolysis (86%), acute hepatitis (51%), and acute renal failure (63%) were the most common clinical conditions following poisoning. Overall mortality was noted in 39 patients (36%) while all other patients achieved complete clinical recovery (64%). In patients with mortality, 20 of 39 (51%) developed acute hepatitis. Most patients (95%) in our study underwent tracheostomy. The frequency of acute hepatitis in PPD intoxication is high in this population, especially in young women. Measures need to be instituted

Nucleos(t)ide analogue (NA) therapy has been reported to reduce the risk of hepatocellular carcinoma (HCC) development in patients with chronic hepatitis B (CHB). However, even during NA therapy, development of HCC has been observed in patients with CHB. Therefore, we clarified the predictive power of clinical factors for HCC incidence using receiver operating characteristic (ROC) analysis that takes time dependence into account. A total of 539 patients with CHB treated with NAs were enrolled. Univariate, multivariate, and time-dependent ROC curves for clinical factors associated with the development of HCC were analyzed. Eighty-one patients developed HCC during the follow-up period (median duration, 5.9 years). α-fetoprotein (AFP) and FIB-4 index at 24 weeks from the initiation of treatment and sex were significantly associated with HCC incidence according to the log-rank test. Cox proportional hazards models including the covariates of sex, hepatitis B genotype, basal core promoter mutations, AFP at 24 weeks, and FIB-4 index at 24 weeks showed that FIB-4 index >2.65 (HR, 5.03; 95% CI, 3.06-8.26; P < 0.001) and male sex were independently associated with HCC incidence. In addition, time-dependent ROC analysis showed that compared with AFP at 24 weeks, FIB-4 index at 24 weeks had higher predictive power for HCC incidence throughout the follow-up period. Elevated FIB-4 index at 24 weeks in patients with CHB receiving NA therapy is a risk factor for developing HCC. The FIB-4 index is an excellent predictor of HCC development. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

The aim of the study was to evaluate the efficacy of vaccination against hepatitis B in HIV infected individuals and the influence of the stage of HIV infection and antiretroviral therapy (HAART). Response for additional doses of hepatitis B vaccine among the patients who do not develop protective anti-HBs level after routine vaccination schedule was analysed. Fifty-four HIV infected individuals, 20 women (37%) and 34 men (63%), 20 to 64 years old (mean age 32 years) were analysed. 32 patients (59.6%), 22 men and 10 women were treated with antiretroviral drugs. Stage of HIV infection was assessed on the basis of data derived from medical records (lowest CD4 cells count, highest viral load), and immunological status at the moment of introduction of vaccination (CD4 cells count, viral load). Efficacy of vaccination was compared with control group, which consisted of 56 healthy volunteers. In both groups hepatitis B virus infection was excluded by serologic tests. HBvaxPro vaccine produced by Merck Sharp & Dohme Company, dose registered for adults (10 ug) was injected at month 0-1-6. Patients with anti-HBs <10 IU/l have received booster doses of vaccine month intervals, no more then three. Protective level of antibodies was found in 52 (92.9%) persons from control group and 32 (63%) HIV infected individuals. Anti-HBs > 100 IU/l was twice more common in control group (80%) than in investigated group (46.3%) (p < 0.001). Protective level of anti-HBs had 14.3% patients with CD4 below 200 cells/pl, none of them had anti-HBs > 100 IU/l. Patients with higher CD4 cell count had better response for vaccination (p = 0.015). Differences between patients with high and low viral load were not statistically significant (p = 0.015). Patients with viral load below 10,000 copies/ml had slightly better response then those with higher viral load. Efficacy of vaccination was also associated with the level of distraction of immunological system before introduction of HAART. Patients with

To assess hepatitis B virus (HBV) reactivation rates in patients with resolved or chronic HBV infection, receiving disease-modifying antirheumatic drugs (DMARDs) and with or without antiviral prophylaxis. We conducted a systematic review and meta-analysis. Electronic searches were conducted in PubMed, Medline, and Embase using Ovid through December 31, 2015. A search strategy was developed for each database using the following inclusion criteria: for participants, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and resolved or chronic HBV infection; for intervention, tumor necrosis factor (TNF) inhibitors or non-TNF biologic or nonbiologic DMARDs; and for outcome, HBV reactivation. Four reviewers independently extracted study data and assessed study quality using the Newcastle-Ottawa Scale. To determine the pooled HBV reactivation rate, the variances of the raw proportions were stabilized using a Freeman-Tukey-type arcsine square root transformation, using a random-effects model. Twenty-five studies met the inclusion criteria. The overall pooled rate of HBV reactivation was 1.6% (95% confidence interval [95% CI] 0.8-2.6) in patients with resolved HBV. Similar rates were observed in resolved patients taking TNF inhibitors (1.4% [95% CI 0.5-2.6]), non-TNF biologics (6.1% [95% CI 0.0-16.6]), and nonbiologic DMARDs (1.7% [95% CI 0.2-4.2]). We also found that the reactivation rate was lower in patients with chronic HBV infection who received antiviral prophylaxis (9.0% [95% CI 4.1-15.5]) than in those who did not (14.6% [95% CI 4.3-29.0]). We found that the HBV reactivation rate in inflammatory arthritis patients receiving DMARDs was low in resolved patients and moderate in patients with chronic HBV infection. Further, lower rates were observed in patients with chronic HBV infection who were using antiviral prophylaxis. © 2017, American College of Rheumatology.

Hepatitis B virus (HBV) vaccination rates for incarcerated adults remain low despite their high risk for infection. This study determined predictors of vaccine completion in homeless adults (N= 297) who reported histories of incarceration and who participated in one of three nurse-led hepatitis programs of different intensity. Moreover time since release from incarceration was also considered. Just over half of the former prisoners completed the vaccine series. Older age (≥40), having a partner, and chronic homelessness were associated with vaccine completion. Recent research has documented the difficulty in providing vaccine services to younger homeless persons and homeless males at risk for HBV. Additional strategies are needed to achieve HBV vaccination completion rates greater than 50% for formerly incarcerated homeless men. © 2012 International Association of Forensic Nurses.

This article reviews the literature on epidemiology and pathogenetic factors of erectile dysfunction in patients with chronic viral hepatic (CVH) diseases in men and the potential implications for diagnosis and treatment. A search to identify original articles, reviews and any other article suitable for the purposes of this review was conducted by combining the following terms: erectile dysfunction and/or sexual dysfunction, chronic viral hepatitis, hepatitis B virus infection and hepatitis C virus infection. The results of this review have led to the following main observations: i) there is scarce documentation on the association between CVH and sexual dysfunction; ii) hormonal impairment seems to be a major component in the development of erectile dysfunction in CVH; however, published evidence concerning the contribution of other pathogenetic factors is rare and inconclusive and iii) available treatment options for CVH potentially contribute to the development of sexual dysfunction in these patients. Due to the scarce body of evidence, more research is needed to better clarify the mechanisms underlying the association between CVH and sexual dysfunction, the impact of therapy and associated comorbidities on sexual dysfunction and the role of pharmacological treatments in the management of these patients.
