Hepatitis B screening practices and viral control among persons living with HIV in urban Senegal.

Chronic hepatitis B virus (HBV) infection affects >10% of the general population and is the leading cause of liver cirrhosis and cancer in West Africa. Despite current recommendations, HBV is often not tested for in clinical routine in the region. We included all people living with HIV (PLWH) in care between March and July 2019 at Fann University Hospital in Dakar (Senegal) and proposed hepatitis B surface antigen (HBsAg) test to those never tested. All HBsAg-positive underwent HIV and HBV viral load (VL) and liver stiffness measurement. We evaluated, using logistic regression, potential associations between patient characteristics and (a) HBV testing uptake; (b) HIV/HBV co-infection among individual HBsAg tested. We determined the proportion of co-infected who had HBV DNA >20 IU/ml on ART and sequenced HBV polymerase in those with HBV replication.of 1076 PLWH in care, 689 (64.0%) had never had an HBsAg test prior to our HBV testing intervention. Women and individuals >40 years old were less likely to have been previously tested. After HBV testing intervention,107/884 (12.1%) PLWH were HBsAg-positive. Seven of 58 (12.1%) individuals newly diagnosed with HIV/HBV co-infection had a detectable HBV VL, of whom five were HIV-suppressed. Two patients on ART including 3TC and AZT as backbone showed the presence of the triple resistance mutation 180M/204I/80V. In this Senegalese urban HIV clinic, the majority of patients on ART had never been tested for HBV infection. One in ten co-infected individuals had a detectable HBV VL despite HIV suppression, and 8% were not receiving a TDF-containing regimen

Prevention and Care of Hepatitis B in Senegal; Awareness and Attitudes of Medical Practitioners.

In highly endemic settings for hepatitis B virus (HBV) infection such as Senegal, access to HBV prevention and care is rapidly evolving. In this context, all medical practitioners should have baseline knowledge on HBV infection and promote access to vaccination, screening, and care. A knowledge and attitudes survey on HBV infection was conducted among a randomly selected sample of medical practitioners in Senegal. Participants were asked to fill-out a questionnaire on the HBV epidemiology, prevention, and treatment. A 60-item knowledge score was computed; the lower quartile of the observed score was used to define poor knowledge. Factors associated with poor knowledge were assessed using a logistic regression model. A total of 127 medical practitioners completed the questionnaire. Only 14 (11.0%) participants knew that HBV vaccine could be safely administered to pregnant women and 65 (51.2%) to newborns. Older practitioners (> 40 years) as well as general practitioners (compared with specialists) were more likely to have a poor knowledge score with odds ratios (ORs) of 3.1 (95% confidence interval [CI] 1.0-9.2) and 2.6 (95% CI 1.0-7.3), respectively. Practitioners who declared not to recommend HBV screening frequently during their consultation were more likely to present a poor knowledge score [OR: 3.0; (95% CI 1.1-8.2)]. As universal HBV screening is being promoted in countries with endemic HBV infection, our finding that poor screening attitudes were associated with a poor knowledge is of concern. There is a need to raise awareness of medical practitioners in Senegal toward universal HBV screening and early vaccination of newborns

Substance use service availability in HIV treatment programs: Data from the global IeDEA consortium, 2014-2015 and 2017.

BackgroundSubstance use is common among people living with HIV and has been associated with suboptimal HIV treatment outcomes. Integrating substance use services into HIV care is a promising strategy to improve patient outcomes.MethodsWe report on substance use education, screening, and referral practices from two surveys of HIV care and treatment sites participating in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. HIV care and treatment sites participating in IeDEA are primarily public-sector health facilities and include both academic and community-based hospitals and health facilities. A total of 286 sites in 45 countries participated in the 2014-2015 survey and 237 sites in 44 countries participated in the 2017 survey. We compared changes over time for 147 sites that participated in both surveys.ResultsIn 2014-2015, most sites (75%) reported providing substance use-related education on-site (i.e., at the HIV clinic or the same health facility). Approximately half reported on-site screening for substance use (52%) or referrals for substance use treatment (51%). In 2017, the proportion of sites providing on-site substance use-related education, screening, or referrals increased by 9%, 16%, and 8%, respectively. In 2017, on-site substance use screening and referral were most commonly reported at sites serving only adults (compared to only children/adolescents or adults and children/adolescents; screening: 86%, 37%, and 59%, respectively; referral: 76%, 47%, and 46%, respectively) and at sites in high-income countries (compared to upper middle income, lower middle income or low-income countries; screening: 89%, 76%, 68%, and 45%, respectively; referral: 82%, 71%, 57%, and 34%, respectively).ConclusionAlthough there have been increases in the proportion of sites reporting substance use education, screening, and referral services across IeDEA sites, gaps persist in the integration of substance use services into HIV care, particularly in relation to screening and referral practices, with reduced availability for children/adolescents and those receiving care within resource-constrained settings
