Abstract Background Although hepatitis B infection is highly endemic in Africa, information on its epidemiology among pregnant women in the region is limited. Therefore, this systematic review provided up-to-date information on the epidemiology of hepatitis B virus (HBsAg) infection among pregnant women in Africa. Methods A systematic review and meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews. The Web of Science, Scopus, PubMed, Google Scholar, and African journals online were searched to identify relevant studies published between January 1, 2015, and May 21, 2024, on hepatitis B virus infection in pregnant women living in Africa. The Joanna Briggs Institute tool was used to assess the methodological qualities of the included studies. The random effects model was used to estimate the pooled prevalence of HBV infection. I2 assessed the amount of heterogeneity. Publication bias was assessed using Egger’s test and a funnel plot. Results We included 91 studies from 28 African countries. The pooled prevalence of hepatitis B infection among pregnant women in Africa was 5.89% (95% CI: 5.26–6.51%), with significant heterogeneity between studies (I2 = 97.71%, p

Abstract Background Aortic valve infective endocarditis (IE) is associated with significant morbidity and mortality. We aimed to describe the clinical profile, risk factors and predictors of short- and long-term mortality in patients with aortic valve IE treated with aortic valve replacement (AVR) compared with a control group undergoing AVR for non-infectious valvular heart disease. Methods Between January 2008 and December 2013, a total of 170 cases with IE treated with AVR (exposed cohort) and 677 randomly selected non-infectious AVR-treated patients with degenerative aortic valve disease (controls) were recruited from three tertiary hospitals with cardiothoracic facilities across Scandinavia. Crude and adjusted hazard ratios (HR) were estimated using Cox regression models. Results The mean age of the IE cohort was 58.5 ± 15.1 years (80.0% men). During a mean follow-up of 7.8 years (IQR 5.1-10.8 years), 373 (44.0%) deaths occurred: 81 (47.6%) in the IE group and 292 (43.1%) among controls. Independent risk factors associated with IE were male gender, previous heart surgery, underweight, positive hepatitis C serology, renal failure, previous wound infection and dental treatment (all p

Abstract Background Universal antiretroviral treatment (ART) for pregnant women has reduced mother-to-child transmission risk significantly. However, not all women on ART are virally suppressed during pregnancy and lactation. In addition to poor adherence to ART, co-infections particularly other sexually transmitted infections (STIs) are known to increase the risk of HIV acquisition and HIV transmission. While the prevalence of STIs during pregnancy has been well studied, the prevalence of STIs in the postpartum period and its association with HIV viral suppression are underreported. Methods In this cross-sectional study, we determined the prevalence of STIs among adolescent girls and young women (AGYW) living with HIV (WLHIV) and without HIV (WNLHIV) at their 6–14 week postnatal clinic visit in a high HIV prevalence district in South Africa. All women were examined for STI-related symptoms and had vaginal swabs collected and stored for later STI testing. Vaginal swabs were tested for Trichomonas vaginalis (T.vaginalis), Chlamydia trachomatis (C. trachomatis), Neisseria gonorrhoeae (N. gonorrhoea) and herpes simplex virus-2 (HSV-2) using PCR. All women were tested for bacterial vaginosis (BV) using the Nugent scoring criteria. WLHIV had a blood sample collected for HIV viral load, Hepatitis B and syphilis. Results Included in this analysis were 82 WLHIV and 102 WNLHIV. Between 6 and 14 weeks postpartum, 40 (21.7%) AGYW tested positive for any STI and among these 15 (37.5%) were symptomatic and received empirical treatment. C. trachomatis was most commonly detected (10.9%), followed by HSV-2 (7.7%), T. vaginalis (3.8%) and N. gonorrhoea (1.6%). WLHIV were more likely to test positive for an STI (OR 2.0; 0.96–3.96) and BV (OR 4.2; 95%CI 2.1–8.1) compared to WNLHIV. Among WLHIV on ART, 70.5% had an undetectable plasma viral load (PVL) and 20.5% had a PVL > 1000 copies/ml. Testing positive for any STI or BV at the postpartum visit was not associated with PVL > 1000 copies/ml (OR 1.33; 95%CI 0.38–4.64). Conclusion We report a high prevalence of largely asymptomatic STIs and BV in the early postpartum period and STIs in WLHIV were not associated with unsuppressed PVL.The high STI positivity rate among WNLHIV has implications for HIV risk during the postpartum period, and subsequently breastfeeding transmission.

Abstract Background Most Chinese blood centers have implemented mini pool (MP) HBV nucleic acid testing (NAT) together with HBsAg ELISA in routine blood donor screening for HBV infection since 2015, and a few centers upgraded MP to individual donation (ID) NAT screening recently, raising urgent need for cost-benefit analysis of different screening strategies. In an effort to prevent transfusion-transmitted infections (TTIs) for HBV, cost-benefit analyses of three different screening strategies: HBsAg alone, HBsAg plus MP NAT and HBsAg plus ID NAT were performed in blood donors from southern China where HBV infection was endemic. Methods MP-6 HBV NAT and ID NAT were adopted in parallel to screen blood donors for further comparative analysis. On the basis of screening data and the documented parameters, the number of window period (WP) infection, HBV acute infection, chronic hepatitis B infection (CHB) and occult hepatitis B infection (OBI) was evaluated, and the potential prevented HBV TTIs and benefits of these three strategies were predicted based on cost-benefit analysis by an estimation model. Results Of 132,323 donations, the yield rate for HBsAg-/DNA + screened by ID NAT (0.12%) was significantly higher than that by MP NAT (0.058%, P

Abstract Background People living with HIV (PLHIV) may have concurrent Hepatitis B Virus (HBV) infection, and certain antiretroviral therapies are recommended for HBV-HIV co-infected individuals. Routine screening for Hepatitis B virus may influence management of antiretroviral therapy for PLHIV, but risk factors for co-infection have not been well defined. The objective of this study was to identify risk factors for HBV infection among PLHIV in South Africa. Methods We conducted a cross-sectional analysis of a prospective, clinic-based cohort study of adults seeking HIV testing from 2013–2017 in Umlazi township, South Africa. Patients newly diagnosed with HIV were enrolled and subsequently tested for Hepatitis B surface antigen positive (HBsAg +). We used a Poisson linear regression model to assess which factors, pertaining to sociodemographic status, medical history, clinical symptoms, mental health were associated with HBV. Results Among 3,105 PLHIV participants in South Africa, 6% were positive for HBV. Males had a higher HBV prevalence (10.4%) than females (5.2%). Within the HBV-positive group, the mean age was 33.2 years, with 38.3% females and 43.9% having completed high school or higher. About 39.9% reported alcohol use, 24.7% had a smoking history, and 8.3% reported substance use in the past year. Older participants born before 1995, when routine infant HBV vaccination was introduced, were more likely to have HBV. In multivariable analyses, smoking history increased HBV risk in females (aPR = 2.58; 95% CI 1.47–2.52), while alcohol use decreased HBV risk in males (aPR = 0.36; 95% CI 0.19–0.70). Conclusions In a South African cohort, roughly one in 16 PLHIV had HBV co-infection, and this rate was higher in males. The most prominent risk factors for HBV infection in PLHIV were alcohol use, higher income, and smoking history, which may help inform targeted treatment and prevention strategies. Creating HBV-specific screening and prevention strategies for PLHIV may be useful for reducing HBV infections.

Abstract Background Acute-on-chronic liver failure (ACLF) is characterized by a systemic inflammatory response, predominantly associated with hepatitis B virus in the Asia-Pacific region, with a high short-term mortality rate. The platelet to high-density lipoprotein ratio (PHR) has been used to predict the prognosis of patients with various inflammatory diseases. We aim to is to use the PHR to predict the short-term prognosis of patients with HBV-ACLF. Method In this study, we retrospectively analyzed clinical data from 270 HBV-ACLF patients. Using logistic regression, we identified independent risk factors for short-term mortality and developed a prognostic model. This model was then validated, compared, and its clinical utility assessed via decision curve analysis (DCA). Results Among the 270 HBV-ACLF patients, 98 patients died within 28 days. The deceased group exhibited a higher proportion of severe hepatic encephalopathy and ascites. Additionally, there was a statistically significant difference (P = 0.046) in the novel inflammation scoring system, PHR, between the two groups. Following stringent variable selection, PHR was identified as a predictive factor for short-term mortality in HBV-ACLF patients using logistic regression analysis (OR: 0.835 (0.756–0.999), P = 0.009), and it exhibited a synergistic effect with certain traditional scores. The prognostic model constructed based on PHR demonstrated a superior ability to predict short-term mortality compared to traditional scores such as Child-Turcotte-Pugh (AUC: 0.889). Evaluation using calibration curves and decision curve analysis (DCA) suggested its practical utility. Conclusion PHR can predict short-term mortality in patients, with a low PHR upon admission being associated with an increased risk of death.

Abstract Background Hepatitis B infection due to poor practices can result in prolonged hospital stays, long-term disability, increased microbial resistance, financial burdens and death. There has been no comprehensive study assessing the practice level of hepatitis B virus infection prevention in Ethiopia despite the high risk of exposure. Thus, this review aimed to assess practice on hepatitis B virus infection prevention in Ethiopia. Methods For published studies, we conducted a thorough search of the PubMed, African Journal Online, Science Direct, Cochrane Library and Google Scholar databases. The data were exported to STATA version 11 (STATA Corp LLC) for meta-analysis. Heterogeneity between the results of the primary studies was assessed using Cochran’s Q chi-square test and quantified with I2 statistics. A random effect model, specifically the DerSimonian and Laird pooled estimate method, was used due to the presence of heterogeneity between the included articles. Results and conclusions Initially, 1738 articles were retrieved through electronic database searching. Of these, 910 were from Google Scholar, 4 from PubMed, 378 from Science Direct, 421 from African Journal Online and 25 from the Cochrane Library. The pooled estimate showed that 41.54% (95% CI: 33.81–49.27, P

by Jonathan J. Woolley, Jesse Fishman, Christina M. Parrinello, Tom O’Connell Background NASH is considered a contributor to atherosclerotic cardiovascular disease (ASCVD) risk; however, its contribution beyond traditional risk factors for CVD, particularly diabetes, is less clearly understood. This study aimed to quantify the cardiovascular-event risk associated with NASH, independent of diabetes status. Methods A cross-sectional analysis was conducted using the 2017–2020 NHANES pre-pandemic cycle. NASH was defined based on presence of steatosis without other causes of liver disease, and FibroScan+AST score from vibration-controlled transient elastography (VCTE). Significant fibrosis (stages F2-F4) was identified by liver stiffness measurement from VCTE. Predicted primary CV-event risk was estimated using both the Pooled Cohort Equations (PCE) and the Framingham Risk Score (FRS). NASH patients were matched with non-NASH controls on age, sex, race/ethnicity, and diabetes status. Weighted logistic regression was conducted, modeling elevated predicted CV risk (binary) as the dependent variable and indicators for NASH / fibrosis stages as independent variables. Results A sample of 125 NASH patients was matched with 2585 controls. NASH with significant fibrosis was associated with elevated predicted 10-year CV risk, although this association was only statistically significant in PCE analyses (odds ratio and 95% CI 2.34 [1.25, 4.36]).

by Harun Mazumder, Md Faruk Hossain, Pratibha Shrestha, Sultan Mahmud, Maidul Husain, Rebeka Ahmed Introduction The people who inject drugs (PWID) are attributed to high-risk groups for transmission of the Hepatitis C virus (HCV). This study assessed the prevalence and associated factors of current HCV infection (CHI) among U.S. general population and PWID of ages between 20 and 59 years old. Methods This study utilized cross-sectional data from the 2009–2018 National Health and Nutrition Examination Survey, conducting separate analyses for the U.S. general population, including PWID and non-PWID, as well as specific analyses focusing solely on PWID. The analytical methods included the estimation of CHI prevalence, Rao-Scott chi-square test to compare CHI-positive and CHI-negative groups, and univariate and multivariable logistic regressions models to evaluate the associated risk factors of CHI. Results The prevalence of CHI among general population and PWID were 1% and 19%, respectively. Compared to non-PWID, the odds of CHI were significantly higher among PWID (OR = 32.6, 95% CI = 17.7–60.3) in general population. Among PWID, male vs. female (OR = 2.6, 95% CI = 1.1–5.9), adults aged 40–59 vs. 20–39 years old (OR = 2.9, 95% CI = 1.2–7.3), Non-Hispanic Black vs. White (OR = 4.6, 95% CI = 1.5–13.6), with high school diploma or less educational attainment vs. above college degree (OR = 3.5, 95% CI = 1.4–9.2) showed higher odds of having CHI. Conclusion The prevalence of CHI was found to be higher among PWID especially those who were male, aged 40–59 years old, Non-Hispanic Black, and had lower educational attainment. Targeted intervention such as screening and awareness program among PWID population is recommended to reduce the burden of new HCV infections in the U.S.

ObjectiveLiver cirrhosis is an increasing cause of morbidity and mortality worldwide with a heavy load on healthcare systems. We analysed the trends in hospitalisations for cirrhosis in Switzerland. DesignCross-sectional study. SettingLarge nationwide inpatient database, years between 1998 and 2020. ParticipantsHospitalisations for cirrhosis of adult patients were selected. Main outcomes and measuresHospitalisations with either a primary diagnosis of cirrhosis or a cirrhosis-related primary diagnosis with a mandatory presence of cirrhosis as a secondary diagnosis were considered following the 10th revision of the International Statistical Classification of Diseases and Related Health Problems codes. Trends in demographic and clinical characteristics, in-hospital mortality and length of stay were analysed. Causes and costs of cirrhosis-related hospitalisations were available from 2012 onwards. ResultsCirrhosis-related hospitalisations increased from 1631 in 1998 to 4052 in 2020. Of the patients, 68.7% were men. Alcohol-related liver disease was the leading cause, increasing from 44.1% (95% CI, 42.4% to 45.9%) in 2012 to 47.9% (95% CI, 46.4% to 49.5%) in 2020. Assessed by exclusion of other coded causes, non-alcoholic fatty liver disease was the second cause at 42.7% (95% CI, 41.2% to 44.3%) in 2020. Hepatitis C virus-related cirrhosis decreased from 12.3% (95% CI, 11.2% to 13.5%) in 2012 to 3.2% (95% CI, 2.7% to 3.8%) in 2020. Median length of stay decreased from 11 to 8 days. Hospitalisations with an intensive care unit stay increased from 9.8% (95% CI, 8.4% to 11.4%) to 15.6% (95% CI, 14.5% to 16.8%). In-hospital mortality decreased from 12.1% (95% CI, 10.5% to 13.8%) to 9.7% (95% CI, 8.8% to 10.7%). Total costs increased from 54.4 million US$ (51.4 million ) in 2012 to 92.6 million US$ (87.5 million ) in 2020. ConclusionsCirrhosis-related hospitalisations and related costs increased in Switzerland from 1998 to 2020 but in-hospital mortality decreased. Alcohol-related liver disease and non-alcoholic fatty liver disease were the most prevalent and preventable aetiologies of cirrhosis-related hospitalisations.

Abstract Background Hepatitis B virus (HBV) infection is a major concern regarding blood safety in countries with a high HBV prevalence, such as China. We aimed to understand the prevalence of HBV infection among blood donors in Chongqing and provide an important basis for developing appropriate blood screening strategies. Methods Dual enzyme-linked immunosorbent assays (ELISAs) for hepatitis B surface antigen (HBsAg) were conducted in parallel with nucleic acid testing (NAT) of donors. All HBsAg-reactive and/or HBV DNA-positive blood samples were tested for HBsAg and hepatitis B DNA levels. Results A total of 117,927 blood donor samples were collected from the Chongqing Blood Center between April 2020 and November 2020. In total, 473 HBV-ineligible samples were retained for HBsAg and DNA confirmation. A total of 272 samples were confirmed to be HBsAg+, including 2 HBV DNA − and 270 HBV DNA + samples. A total of 201 donations were HBsAg−, including 72 HBV DNA − samples. The rate of HBV infection was 65.33% (309/473) in men, which was significantly higher than that in women (p

Acute liver failure (ALF) is a life-threatening disorder characterised by rapid deterioration of liver function, coagulopathy, and hepatic encephalopathy in the absence of pre-existing liver disease. The cause of ALF varies across the world. Common causes of ALF in adults include drug toxicity, hepatotropic and non-hepatotropic viruses, herbal and dietary supplements, antituberculosis drugs, and autoimmune hepatitis. The cause of liver failure affects the management and prognosis, and therefore extensive investigation for cause is strongly suggested.

Abstract In 2023, passive laboratory-based surveillance showed an increase in hepatitis A virus (HAV) infection. We investigated hepatitis A incidence using the notifiable medical condition surveillance system (NMCSS) data and molecularly characterised positive blood samples from the Western Cape province for 2023. All HAV IgM seropositive cases from the NMCSS from 1 January to 31 October 2023 in South Africa were investigated. HAV RNA from blood samples that had tested positive for HAV IgM from Western Cape was amplified in the VP1/P2B junction and sequenced (3500Xl Genetic Analyser). Sequences were assembled, aligned (Sequencher) and analysed (Aliview 1.27 and MEGA11). Statistical analysis was performed using Excel and the CuSum2 Threshold to determine suspected outbreaks. In 2023, the incidence of HAV IgM was 6.28/100,000 in South Africa, with the highest incidence in Western Cape province (15.86/100,000). Children aged 5 to 14 years were affected the most in the Western Cape. The positive cases in the Western Cape were above the CuSum2 threshold from January to May 2023, with the highest incidence observed in the City of Cape Town Metropolitan (14.8/100,000). Genotyping was successfully performed on 92.7% (139/150) of serum samples, for which the IB sub-genotype was detected. Three primary mutations R63K, R71S and M104I were observed in more than 49% of the samples. Most of the samples sequenced belonged to patients residing in areas close to each other within the City of Cape Town Southern, Western, and Mitchells Plain sub-districts. The CuSum2 threshold method allowed the identification of suspected HAV outbreaks in the districts within the Western Cape in 2023 while genotyping identified clusters of sub-genotype IB. Genotyping could assist with determining the common source of infection during an outbreak, especially if coupled with epidemiological and geographical data. Further active surveillance can assist in investigating the HAV risk factors for targeted public health responses.

by Namsoo Kim, Sinyoung Kim, Jong Rak Choi, Younhee Park Background/aims Autoimmune hepatitis (AIH) is characterized by the presence of auto-antibodies and high blood immunoglobulin G (IgG) levels. In this study, the line immunoassay (LIA) was designed to assess various autoantibodies. Methods In total, 1371 patients who underwent autoimmune liver disease antibody testing between July 2019 and November 2022 were enrolled. Autoantibodies including antinuclear antibody (ANA) and anti-mitochondrial antibody (AMA) were tested, and clinical data were collected. Statistical analyses were performed by categorizing the data based on diagnosis and IgG quantification separately. A scoring system was applied to identify individuals with AIH. Patients were also classified into the AIH and non-AIH groups. Results The positivity rate for ANA was 80.2% in the AIH group. The IgG-high group had a high likelihood of the presence of detectable autoantibodies, with anti-Ro-52 being the most frequently detected antibody using LIA. The \'Consider AIH\' and \'AMA\' groups had 3–4 times more patients in the IgG-high group than in the \'Not Considered\' group. Conclusions Among autoantibodies, the prevalence of ANA was the highest. As per LIA results, anti-Ro-52 was the most prevalent. AIH cannot be diagnosed based on IgG levels alone and must be distinguished via autoantibody testing. Therefore, extensive testing, including autoantibodies, IgG, ANA, and liver enzyme levels, will help accurately diagnose AIH.

Abstract Background Acute hepatitis E infection (HEV), with its high incidence in Europe, should be considered as a differential diagnosis of acute viral hepatitis and can in some cases manifest with pronounced neurological symptoms. Clinical Case We report on a 33-year-old female patient with severe arthralgia, myalgia, headache and psychomotor deterioration. Laboratory analyses showed elevated transaminases without signs of cholestasis. Acute hepatitis E virus infection was detected in serum. She reported fatigue and dysesthesias not responsive to analgesics. Cerebrospinal fluid (CSF) analysis revealed an inflammatory syndrome. HEV RNA was detected in the CSF. The infection remained mild, but dysesthesias persisted. Eight weeks after the first admission, the symptoms worsened again. Complete and sustained remission was achieved following intravenous corticosteroid treatment. Conclusion In patients with acute neurological symptoms and liver enzyme elevation, HEV infection should be considered. Neurologic symptoms such as fatigue, arthralgia, myalgia and dysesthesia along with psychomotor retardation should prompt CSF analysis.

In Reply We thank Dr Fujieda, Ms Yu, and Dr Tu and colleagues for their Letters about our randomized clinical trial of aspirin for the treatment of liver fat in patients with MASLD without cirrhosis. We agree that our study findings of reduced liver fat content and reductions in markers of liver inflammation and fibrosis with aspirin, compared with placebo, warrant further study in larger randomized trials with longer duration of follow-up and with inclusion of both histological and clinical end points, as we highlighted in the article. Nevertheless, we would emphasize that liver fat content quantified by magnetic resonance imaging is a well-established and accepted end point in early-phase MASLD clinical trials, and reducing hepatic fat by 30 percentage points or greater is widely considered a meaningful treatment effect, based on corresponding improvements in steatohepatitis and fibrosis. Furthermore, a 3- to 6-month intervention represents a reasonable and appropriate duration for most early-phase MASLD clinical trials, as it provides sufficient time to ascertain meaningful changes in MASLD histology while minimizing potential risks from a novel therapy. Thus, our findings demonstrating the efficacy of aspirin in reversing liver fat and improving markers of inflammation and fibrosis after 6 months of treatment provide a strong preliminary foundation for future, larger-scale clinical trials with longer follow-up time and with both histological and clinical end points.

Abstract Background Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) co-infection are significant public health issues, despite the availability of an effective HBV vaccine for nearly three decades and the great progress that has been made in preventing and treating HIV. HBV and HIV both modulate micro-ribonucleic acids (microRNA) expression to support viral replication. The aim of this study was to describe the pattern of microRNA expression in patients coinfected with chronic HBV and HIV with varying disease severity, as indicated by Hepatitis B e antigen (HBeAg) status, HBV viral load, alanine transaminase (ALT) levels, and HIV viral load. Methods Plasma microRNAs, specific to HBV, were measured by quantitative real-time polymerase chain reaction (qRT-PCR) in HBV and HIV-negative healthy controls (n = 23) and patients coinfected with chronic HBV-HIV (n = 50). MicroRNA expression levels were compared between patients with high vs low HBV viral load, HBeAg positive vs HBeAg negative, high vs low ALT levels, and high vs low HIV viral load. Additionally, HBV viral load, ALT levels, and HIV viral load were correlated with microRNA expression levels. Results Significantly higher expression levels of selected microRNAs were observed in chronic HBV-HIV coinfected patients compared to healthy controls. Significantly higher expression levels of hsa-miR-122-5p, hsa-miR-192-5p, and hsa-miR-193b-3p were observed in patients with high HBV viral load compared with low HBV viral load patients, and the levels of these microRNAs were correlated with HBV viral load levels. Significantly higher levels of hsa-miR-15b-5p and hsa-miR-181b-5p were observed in HBeAg-negative patients. Conclusion This study demonstrates the potential use of hsa-miR-15b-5p, hsa-miR-122-5p, hsa-miR-181b-5p, hsa-miR-192-5p and hsa-miR-193b-3p as additional diagnostic biomarkers in chronic HBV disease progression.

Abstract Background and Aims Data on the safety and effectiveness of tenofovir alafenamide (TAF) plus peginterferon-alpha (Peg-IFN-α) in children with chronic hepatitis B (CHB) are lacking. The current study aimed to present the characteristics of four pediatric CHB patients who obtained a functional cure by using TAF and Peg-IFN-α. Methods In this case series study initiated in May 2019, ten children who had no clinical symptoms or signs received response-guided (HBV DNA undetectable, hepatitis B e antigen [HBeAg] loss or seroconversion, and hepatitis B surface antigen [HBsAg] loss or seroconversion) and functional cure-targeted (HBsAg loss or seroconversion) TAF (25 mg/d, orally) plus Peg-IFN-α-2b (180 µg/1.73m2, subcutaneously, once weekly) in combination (9/10) or sequential (1/10) therapy. The safety and effectiveness of these treatments were monitored. Results As of April 2024, four out of ten children obtained a functional cure after a mean of 31.5 months of treatment, and the other six children are still undergoing treatment. These four cured children, aged 2, 4, 8, and 6 years, were all HBeAg-positive and had alanine aminotransferase levels of 80, 47, 114, and 40 U/L; HBV DNA levels of 71200000, 93000000, 8220, and 96700000 IU/mL; and HBsAg levels of 39442.8, 15431.2, 22, and 33013.1 IU/mL, respectively. During treatment, all the children (10/10) experienced mild or moderate adverse events, including flu-like symptoms, anorexia, fatigue, and cytopenia. Notably, growth retardation (8/10) was the most significant adverse event; and it occurred in three cured children (3/4) treated with combination therapy and was present to a low degree in the other cured child (1/4) treated with sequential therapy. Fortunately, all three cured children recovered to or exceeded the normal growth levels at 9 months posttreatment. Conclusions TAF plus Peg-IFN-α-2b therapy is potentially safe and effective for pediatric CHB patients, which may provide important insights for future clinical practice and study designs targeting functional cures for children with CHB.

IntroductionPrevious studies have shown that substantial percentages of emergency department (ED) patients in the USA recommended for HIV or hepatitis C (HCV) decline testing. Evidence-based and cost-effective interventions to improve HIV/HCV testing uptake are needed, particularly for people who inject drugs (PWIDs) (currently or formerly), who comprise a group at higher risk for these infections. We developed a brief persuasive health communication intervention (PHCI) designed to convince ED patients who had declined HIV/HCV testing to agree to be tested. In this investigation, we will determine if the PHCI is more efficacious in convincing ED patients to be tested for HIV/HCV when delivered by a video or in person, and whether efficacy is similar among individuals who currently, previously or never injected drugs. Methods and analysisWe will conduct a multisite, randomised controlled trial comparing PHCIs delivered by video versus in person by a health educator to determine which delivery method convinces more ED patients who had declined HIV/HCV testing instead to be tested. We will stratify randomisation by PWID status (current, former or never/non-PWID) to permit analyses comparing the PHCI delivery method by injection-drug use history. We will also perform a cost-effectiveness analysis of the interventions compared with current practice, examining the incremental cost-effectiveness ratio between the two interventions for the ED population overall and within individual strata of PWID. As an exploratory analysis, we will assess if a PHCI video with captions confers increased or decreased acceptance of HIV/HCV testing, as compared with a PHCI video without captions. Ethics and disseminationThe study protocol has been approved by the institutional review board of the Icahn School of Medicine. The results will be disseminated at international conferences and in peer-reviewed publications. Trial registration number NCT05968573.

PCB 126 is associated with steatohepatitis, fibrosis, cirrhosis, and other hepatic injuries. These disorders can be regulated by microRNAs (miRNAs). Therefore, this study aimed to investigate the role of miRNAs in non-alcoholic fatty liver disease associated with exposure to PCB 126. Adult male C57BL/6 mice were exposed to PCB 126 (5 μmol/kg of body weight) for 10 weeks. The PCB group showed lipid accumulation in the liver in the presence of macro- and microvesicular steatosis and fibrosis with increased inflammatory and profibrotic gene expression, consistent with non-alcoholic steatohepatitis (NASH). PCB exposure also upregulated miR-155 and miR-34a, which induce the expression of proinflammatory cytokines and inflammation in the liver and reduce the expression of peroxisome proliferator-activated receptor α, which, in turn, impairs lipid oxidation and hepatic steatosis. Therefore, the present study showed that PCB 126 induced NASH via potential mechanisms involving miR-155 and miR-34a, which may contribute to the development of new diagnostic markers and therapeutic strategies.

Abstract Objectives Hepatitis B is a liver disease caused by Hepatitis B virus (HBV) infection and is highly prevalent in China. To better understand the epidemiological characteristics of hepatitis B in China and develop effective disease control strategies, we employed temporal and spatial statistical methods. Methods We obtained HBV incidence data from the Public Health Science Data Center of the Chinese Center for Disease Control and Prevention for the years 2006 to 2018. Using Geographic Information System (GIS) and SaTScan scanning technology, we conducted spatial autocorrelation analysis and spatiotemporal scan analysis to create a map and visualize the distribution of hepatitis B incidence. Results While hepatitis B incidence rebounded in 2011 and 2017, the overall incidence in China decreased.In the trend analysis by item, the incidence varies from high to low. The global spatial autocorrelation analysis revealed a clustered distribution, and the Moran index analysis of spatial autocorrelation within local regions identified five provinces as H-H clusters (hot spots), while one province was an L-L cluster (cold spot). Spatial scan analysis identified 11 significant spatial clusters. Conclusions We found significant clustering in the spatial distribution of hepatitis B incidence and positive spatial correlation of hepatitis B incidence in China. We also identified high-risk times and regional clusters of hepatitis B incidence.

Abstract Background Globally, around 7 to 20 million people are believed to be suffering from coinfection with both hepatitis B virus (HBV) and hepatitis C virus (HCV). The loop-mediated isothermal amplification (LAMP) approach, introduced by Notomi and colleagues, has undergone substantial advancements as an effective molecular tool that enables the simultaneous analysis of multiple samples in a single tube. Methods The present study examined the simultaneous detection of HBV and HCV in a single tube using melt curve analysis multiplex LAMP (mLAMP), which is based on the identification of unique melting peak temperatures. Selected regions for primer design including the S gene of HBV and the UTR gene of HCV. Primer optimization is initially performed through individual HBV and HCV LAMP analysis. Following the optimization process, the mLAMP assay was evaluated by optimizing the multiplex reaction mixture, determining the reaction time, and analyzing the limit of detection (LOD). The results are also analyzed using lateral flow dipsticks (LFD), which enable the visual detection of HBV and HCV by adding 20 pmol FITC-labeled LF primers into the reaction mixture prior the mLAMP. Results The LOD for the mLAMP assay was determined as 10 copies/µl, and no cross-reactivity with other microorganisms was detected. The detection results obtained from patient plasma were also visually demonstrated using LFD, and displayed significant concordance with those obtained from Real-Time Polymerase Chain Assay. The mLAMP assay revealed a diagnostic sensitivity of 95% for detecting the HBV, and LOD is 90% for HCV. The overall diagnostic sensitivity of the mLAMP assay for both viruses was 85%. The assay confirmed a specificity of 100%. Conclusion The mLAMP assay displays significant promise for analyzing coinfected samples by simultaneously detecting the dual targets HBV and HCV within a set temperature of 62 °C, all within a time frame of 1 h. Additionally, when paired with disposable LFD, the mLAMP assay enables rapid visual detection of assay results in a matter of minutes. The result contributes to the mLAMP assay being highly suitable for coinfection screening, particularly in field conditions.

Abstract Background This study aimed to determine the prevalence and factors associated with susceptibility to hepatitis B virus (HBV) among cisgender men who have sex with men (MSM) on HIV pre-exposure prophylaxis (PrEP) in Northeastern Brazil. Methods This was a cross-sectional, analytical study conducted between September 2021 and June 2023. Participants underwent structured interviews to collect sociodemographic and clinical information, including hepatitis B vaccination history, HIV PrEP use and sexual health history. Blood samples were collected for hepatitis B serologic testing: HBV surface antigen (HBsAg), HBV surface antibody (anti-HBs), total and IgM HBV core antibody (anti-HBc). HBV susceptibility was defined as nonreactive results for all these serological markers. Results A total of 287 participants were enrolled into the study. The median age of the individuals was 31 years (interquartile range: 27; 36). HBV susceptibility was found in 58 out 286 individuals (20.3%; 95% CI: 15.9–25.2). Seventy-six percent of the participants reported completing the three-dose hepatitis B vaccine schedule. Susceptibility was significantly associated with a monthly income ≤ 5 minimum wages (PR: 2.02; 95% CI: 1.01–4.05), lack of complete hepatitis B vaccination schedule (PR: 4.52; 95% CI: 2.89–7.06), initiation of HIV PrEP (PR: 2.18; 95% CI: 1.21–3.94), duration of six months of HIV PrEP (PR: 2.16; 95% CI: 1.19–3.91), absence of tattoos (PR: 1.55; 95% CI: 1.00–2.40) and no history of sexually transmitted infections (PR: 1.65; 95% CI: 1.07–2.54). Conclusion Our findings highlight the significant burden of HBV susceptibility among MSM on HIV PrEP in Northeastern Brazil. Socioeconomic factors, vaccination status, PrEP use and sexual health behaviors play critical roles in determining susceptibility to HBV. Integrating hepatitis B screening and vaccination into PrEP services is critical for identifying and addressing HBV susceptibility among MSM. Interventions aimed at increasing vaccination coverage and promoting safer sexual practices are essential for mitigating the burden of HBV infection in this population.

by Degsew Ewunetie Anteneh, Eden Bishaw Taye, Asmra Tesfahun Seyoum, Alemken Eyayu Abuhay, Endeshaw Admassu cherkose Background Co-infections involving human immunodeficiency virus (HIV), hepatitis B virus (HBV), and syphilis pose significant public health problems during pregnancy. It can increase the risk of adverse outcomes for both the woman and the infant more than each infection alone does. However, the magnitude of these co-infections remains insufficiently documented. Hence, this study aimed to determine the seroprevalence of HIV, HBV, and syphilis co-infections and associated risk factors among pregnant women attending antenatal care in Amhara region referral hospitals in northern Ethiopia. Methods A hospital-based cross-sectional study was conducted in Amhara regional state referral hospitals from January 1 to February 30, 2024, among 606 pregnant women. Pregnant women were selected using a systematic random sampling technique. An interviewer-administered questionnaire and chart review were used to collect data. Data were analyzed in SPSSV26.0. Descriptive statistics were used to determine the magnitude of co-infections, and binary logistic regression was used to determine associated factors. Variables with a P-value < 0.05 were used to declare statistical significance. Result Overall, 4.1% (95% CI: 2.7, 6.1) of pregnant women were co-infected. The prevalence of specific co-infections was 2% (95% CI: 1, 3.5) for HIV/HBV, 1.3% (95% CI: 0.6, 2.6) for HIV/syphilis, and 0.8% (95% CI: 0.3, 1.9) for HBV/syphilis. No cases of triple co-infection were observed. Women with a history of unsafe sex (AOR = 8.2, 95% CI: 1.5, 16.7) and incarceration (AOR = 9.3, 95% CI: 1.6, 20.8) were associated with HIV/syphilis co-infection. For HIV/HBV co-infection, contact with jaundice patients (AOR = 5.5, 95% CI: 1.3, 22.5) and women with a history of STIs (AOR = 4.6, 95% CI: 1.4, 14.9) was significantly associated. Women with STI history (AOR = 6.3, 95% CI: 1.2, 15.9) were also significantly associated with HBV/syphilis co-infection. Conclusion Despite the government’s elimination efforts, a relatively high prevalence of coinfections with the infections studied was found among pregnant women. Therefore, HIV, HBV, and syphilis testing and treatment packages should be strengthened by targeting pregnant women with a history of STIs, contact with patients with jaundice, a history of incarceration, and unsafe sex.

Abstract Background The objective of this study is to estimate the burden of selected immunization-preventable infectious diseases in Spain using the Burden of Communicable Diseases in Europe (BCoDE) methodology, as well as focusing on the national immunization programme and potential new inclusions. Methods The BCoDE methodology relies on an incidence and pathogen-based approach to calculate disease burden via disability-adjusted life year (DALY) estimates. It considers short and long-term sequelae associated to an infection via outcome trees. The BCoDE toolkit was used to populate those trees with Spanish-specific incidence estimates, and de novo outcome trees were developed for four infections (herpes zoster, rotavirus, respiratory syncytial virus [RSV], and varicella) not covered by the toolkit. Age/sex specific incidences were estimated based on data from the Spanish Network of Epidemiological Surveillance; hospitalisation and mortality rates were collected from the Minimum Basic Data Set. A literature review was performed to design the de novo models and obtain the rest of the parameters. The methodology, assumptions, data inputs and results were validated by a group of experts in epidemiology and disease modelling, immunization and public health policy. Results The total burden of disease amounted to 163.54 annual DALYs/100,000 population. Among the selected twelve diseases, respiratory infections represented around 90% of the total burden. Influenza exhibited the highest burden, with 110.00 DALYs/100,000 population, followed by invasive pneumococcal disease and RSV, with 25.20 and 10.57 DALYs/100,000 population, respectively. Herpes zoster, invasive meningococcal disease, invasive Haemophilus influenza infection and hepatitis B virus infection ranked lower with fewer than 10 DALYs/100,000 population each, while the rest of the infections had a limited burden (

Abstract Background Up to now several studies estimate the prevalence of HBV, HCV, and TB among people living with HIV (PLWH) in Iran; however, their results are inconsistent. This study aimed to estimate the overall prevalence of HBV, HVC, and TB among Iranian PLWH. Methods In this systematic review and meta-analysis six databases including Medline, Web of Science, Scopus, MagIran, Scientific Information Database (SID), and Barakat Knowledge network system were searched up to October 2023 with no language restriction. All studies estimated the prevalence of HBV, HCV, and TB among PLWH in Iran were included. The random-effects model was used to report the study estimates. Results were reported at a 95% confidence interval (CI). Results Out of 1050 retrieved references, 58 articles met the eligibility criteria. Overall among PLWH, HBV prevalence was 13.0% (95% CI: 11.0, 15.0), HCV prevalence was 54% (95% CI: 45.0, 64.0), and TB prevalence was 19% (95% CI: 13.0, 24.0). The results from multivariate meta-regression analysis showed no statistically significant association between HBV and TB prevalence with the year of study, quality of studies, age, gender, and persons who inject drugs (PWID). HCV prevalence was significantly associated with PWID. Conclusion We found HBV, HCV, and TB infections are common among PLWH in Iran and required to be screened and treated with effective and timely services.

by Muhammad Azeem, Ghulam Mustafa, Sibtain Ahmed, Amna Mushtaq, Muhammad Arshad, Muhammad Usama, Muhammad Farooq Viral diseases pose a serious global health threat due to their rapid transmission and widespread impact. The RNA-dependent RNA polymerase (RdRp) participates in the synthesis, transcription, and replication of viral RNA in host. The current study investigates the antiviral potential of secondary metabolites particularly those derived from bacteria, fungi, and plants to develop novel medicines. Using a virtual screening approach that combines molecular docking and molecular dynamics (MD) simulations, we aimed to discover compounds with strong interactions with RdRp of five different retroviruses. The top five compounds were selected for each viral RdRp based on their docking scores, binding patterns, molecular interactions, and drug-likeness properties. The molecular docking study uncovered several metabolites with antiviral activity against RdRp. For instance, cytochalasin Z8 had the lowest docking score of –8.9 (kcal/mol) against RdRp of SARS-CoV-2, aspulvinone D (–9.2 kcal/mol) against HIV-1, talaromyolide D (–9.9 kcal/mol) for hepatitis C, aspulvinone D (–9.9 kcal/mol) against Ebola and talaromyolide D also maintained the lowest docking score of –9.2 kcal/mol against RdRp enzyme of dengue virus. These compounds showed remarkable antiviral potential comparable to standard drug (remdesivir –7.4 kcal/mol) approved to target RdRp and possess no significant toxicity. The molecular dynamics simulation confirmed that the best selected ligands were firmly bound to their respective target proteins for a simulation time of 200 ns. The identified lead compounds possess distinctive pharmacological characteristics, making them potential candidates for repurposing as antiviral drugs against SARS-CoV-2. Further experimental evaluation and investigation are recommended to ascertain their efficacy and potential.

by Tadesse Atanaw, Getu Girmay, Aragaw Zemene, Muluneh Assefa, Tewodros Eshetie, Gezahegn Bewket, Fikadu Alemiye, Debaka Belete, Nega Birhane Background Cancer patients are prone to infections such as hepatitis B virus (HBV) and hepatitis C virus (HCV), which pose a major public health challenge, especially in developing countries. However, little is known about the magnitude of these infections among cancer patients in Ethiopia. Thus, this study determined the prevalence of HBV and HCV in cancer patients at the Oncology Treatment Center, Gondar, Northwest Ethiopia. Materials and methods An institutional-based cross-sectional study was conducted on 115 cancer patients from 15 April to 22 July 2023 at the Oncology Treatment Center, Gondar, Northwest Ethiopia. Sociodemographic, clinical, and other relevant data were collected using a pretested structured questionnaire. Five milliliters of venous blood were collected using a vacutainer tube, serum was harvested and tested for HBV and HCV using a one-step HBsAg and anti-HCV test strip with further confirmation through an ELISA test kit. Data were analyzed using SPSS version 20 and Fisher exact test was used to determine the association between HBV/HCV infection and associated factors. Results Out of 115 cancer patients, the majority (62.6%) were females. The median age was 50 (IQR; 40–56) years. The overall prevalence of HBV and HCV infections was 4.3% (95% CI; 0.6–8%) and 6.1% (95% CI; 1.7–10.5%), respectively. Sex was significantly associated with the prevalence of HCV (p = 0.011) with higher anti-HCV positivity in males (14%) than in females (1.4%). Conclusions In this study, the prevalence of HCV was higher and the HBV prevalence was intermediate in cancer patients. To reduce the burden of HBV and HCV infections, it is crucial to provide access to HBV and HCV screening services, strengthen vaccination, and improve prompt treatment in cancer patients.

ObjectiveThere is limited information regarding the incidence of treatment-related adverse events (AE) following antiretroviral therapy (ART) in women. So, this review aimed to describe the incidence of AE of ART in women living with HIV/AIDS. DesignSystematic review and meta-analysis. Data sourcesMedline, Embase, Cochrane Library, Epistemonikos, Lilacs and Who Index, from inception to 9 April 2023. Eligibility criteriaWe included randomised controlled trials with at least 12 weeks of follow-up and evaluated AE of ART in women at any age living with HIV/AIDS, without restrictions on status, year or language of publication. We excluded post hoc or secondary analyses and open-label extensions without comparator, and trials involving pregnant or breastfeeding women or with a focus on coinfection with tuberculosis, hepatitis B or C. The primary outcomes were the incidence rate of participants with any clinical and/or laboratory AE related or not to ART and treatment discontinuation. Data extraction and synthesisTwo independent reviewers extracted data and assessed the risk of bias using Cochrane’s risk of bias tool 2. We used Bayesian random-effects meta-analysis to summarise event rates. Results were presented as event rates per 1000 person-years (95% credibility intervals, 95% CrI). The pooled incidence rate per 1000 person-years adjusted for duration and loss to follow-up was estimated. We assessed the certainty of the evidence using Grading of Recommendations, Assessment, Development and Evaluation. ResultsA total of 24 339 studies were identified for screening, of which 10 studies (2871 women) met the eligibility criteria, with 11 different antiretrovirals (ARVs) regimens. Seven studies included exclusively women, while in the remaining three, the proportion of women ranged from 11% to 46%. Nine studies received industry funding. The pooled analysis showed a mean incidence rate of ART-related clinical and laboratory AE of 341.60 events per 1000 person-years (95% CrI 133.60–862.70), treatment discontinuation of 20.78 events per 1000 person-years (95% CrI 5.58–57.31) and ART-related discontinuation of 4.31 per 1000 person-years (95% CrI 0.13–54.72). Summary estimates were subject to significant uncertainty due to the limited number of studies and sparse data. The certainty of the evidence was graded as very low for all outcomes assessed. ConclusionExisting randomised trials do not provide sufficient evidence on the incidence rates of safety outcomes from antiretroviral treatment in women living with HIV/AIDS. Large comparative studies in well-characterised populations are needed to provide a more comprehensive landscape of the safety profile of these ARV therapies in women with HIV/AIDS.

Abstract Background Viruses, which are transmitted mainly via the digestive tract, are responsible for the high morbidity and mortality of diseases, particularly in low-income countries. Although several studies have established the prevalence and characterization of various enteric viruses in Burkina Faso, to date, no aggregate data have been released. Objective Our objective was to describe the available data on the prevalence and circulating genotypes of enteric pathogen viruses responsible for human infections in Burkina Faso by carrying out a systematic review and meta-analysis. Methods Potentially relevant studies were identified by a search of PubMed, ScienceDirect, Google Scholar, university libraries and by a manual search of the reference lists of identified studies. The search with no restrictions on language or age was limited to studies conducted only in Burkina. Study selection, data extraction, and methodological quality of the included studies were performed independently by two investigators. Heterogeneity between studies was assessed using the Cochrane Q test and I2 test statistics based on the random effects model. Comprehensive meta-analysis (CMA 3.7) was employed to compute the pooled prevalence of pathogens identified in the studies. Results Forty-three (43) studies reporting 4,214 diagnosed cases in all aged human populations were selected. Overall, 72.6% of the pathogens diagnosed were gastroenteritis, and 27.2% were entero-transmissible hepatitis viruses. Rotavirus was the most common cause of human viral gastroenteritis, accounting for 27.7% (95% CI: 20.9 - 35.8) of the cases, followed by norovirus (16% (95% CI: 12.25 - 20.6)) and sapovirus (11.2% (95% CI: 6.2 - 19.4)). In terms of human entero-transmissible infections, hepatitis A virus (HAV) was the most prevalent (52% [95% CI: 14.2–87.7] of total antibodies), followed by hepatitis E virus (HEV) (28.3% [95% CI: 17.7–42]). Conclusions This study highlights the substantial burden of viral enteric infections and highlights the need for more molecular epidemiological studies to improve preventive measures against these viruses.

Abstract Background Illicitly manufactured fentanyl (IMF) increases overdose mortality, but its role in infectious disease transmission is unknown. We examined whether IMF use predicts hepatitis C virus (HCV) and human immunodeficiency virus (HIV) incidence among a cohort of people who inject drugs (PWID) in San Diego, California and Tijuana, Mexico.Methods PWID were recruited during 2020–2022, undergoing semi-annual interviewer-administered surveys and HIV and HCV serological rapid tests through 2024. Cox regression was conducted to examine predictors of seroconversion considering self-reported IMF use as a 6-month lagged, time-dependent covariate.Results Of 398 PWID at baseline, 67% resided in San Diego, 70% were male, median age was 43 years, 42% reported receptive needle sharing, and 25% reported using IMF. HCV incidence was 14.26 per 100 person-years (95% confidence interval [CI]: 11.49–17.02), and HIV incidence was 1.29 (95% CI: .49–2.10). IMF was associated with HCV seroconversion, with a univariable hazard ratio (HR) of 1.64 (95% CI: 1.09–2.40), and multivariable HR of 1.57 (95% CI: 1.03–2.40). The direction of the relationship with HIV was similar, albeit not significant (HR 2.39; 95% CI: .66–8.64).Conclusions We document a novel association between IMF and HCV seroconversion among PWID in Tijuana–San Diego. Few HIV seroconversions (n = 10) precluded our ability to assess if a similar relationship held for HIV. IMF\'s short half-life may destabilize PWID—increasing the need for repeat dosing and sharing smoking materials and syringes. New preventive care approaches may reduce HCV transmission in the fentanyl era.

Abstract T-cell immunoglobulin and mucin domain-containing molecule 4 (Tim-4) is an immune checkpoint molecule, which involves in numerous inflammatory diseases. Tim-4 is mainly expressed on antigen presenting cells. However, increasing evidences have shown that Tim-4 is also expressed on natural killer T (NKT) cells. The role of Tim-4 in maintaining NKT cell homeostasis and function remains unknown. In this study, we explored the effect of Tim-4 on NKT cells in acute liver injury. This study found that Tim-4 expression on hepatic NKT cells was elevated during acute liver injury. Tim-4 deficiency enhanced IFN-γ, TNF-α expression while impaired IL-4 production in NKT cells. Loss of Tim-4 drove NKT cell effector lineages to be skewed to NKT1 subset. Furthermore, Tim-4 KO mice were more susceptible to α-GalCer challenge. In conclusion, our findings indicate that Tim-4 plays an important role in regulating homeostasis and function of NKT cells in acute liver injury. Therefore, Tim-4 might become a new regulator of NKT cells and a potential target for the therapy of acute hepatitis.

Abstract Background and aims Numerous HBeAg-positive chronic hepatitis B (CHB) patients with persistently normal ALT have significant liver histopathology. It is imperative to identify true “immune tolerant” patients. We aimed to evaluate the liver histopathology features of HBeAg-positive CHB patients with normal ALT and the incidence of liver cirrhosis and HCC in CHB patients during follow-up. Methods 179 HBeAg-positive CHB patients with normal ALT who performed liver biopsy from 2009 to 2018 were retrospectively analyzed. Liver necroinflammation ≥ G2 and/or liver fibrosis ≥ S2 was defined as significant liver histopathological change. Results 57.5% patients were in the indeterminate phase with significant liver histological changes. The proportion of the patients with evident liver necroinflammation was higher in the high-normal ALT group (21-40U/L) when compared with the low-normal ALT group (≤ 20 U/L) (51.3% vs. 30.0%, p

Abstract Background The use of telemedicine has grown significantly since the COVID-19 pandemic and has the potential to improve access to specialized care for otherwise underserved populations. Incarcerated people living with HIV (PLWH) could potentially benefit from expanded access to HIV care through telemedicine. Methods All PLWH who were incarcerated within the Tennessee Department of Corrections and received care through the HIV telemedicine clinic at Regional One Hospital between 5/1/2019 through 2/28/2022 were identified from the electronic health records (EHR). Demographics, laboratory data, vaccine history, and treatment outcomes were abstracted from the EHR. Retention in care and viral suppression were defined using Centers for Disease Control and Prevention definitions. Results Of the 283 incarcerated PLWH receiving care from this telemedicine clinic, 78% remained retained in care and 94% achieved or maintaining viral suppression at 12 months. Many preventative care measures remained unperformed or undocumented, including vaccinations and testing for concurrent sexually transmitted infections. There were 56 patients (20%) found to have chronic hepatitis C in this population, with 71% either cured or still on treatment in this study period. Conclusions Retention in care and viral suppression rates were excellent among incarcerated PLWH receiving telemedicine care for their HIV. HIV related primary health care screenings and vaccinations, however, were less consistently documented and represent areas for improvement.
