RESUMEN

Importance: Facilitated telemedicine may promote hepatitis C virus elimination by mitigating geographic and temporal barriers. Objective: To compare sustained virologic responses for hepatitis C virus among persons with opioid use disorder treated through facilitated telemedicine integrated into opioid treatment programs compared with off-site hepatitis specialist referral. Design, Setting, and Participants: Prospective, cluster randomized clinical trial using a stepped wedge design. Twelve programs throughout New York State included hepatitis C-infected participants (n = 602) enrolled between March 1, 2017, and February 29, 2020. Data were analyzed from December 1, 2022, through September 1, 2023. Intervention: Hepatitis C treatment with direct-acting antivirals through comanagement with a hepatitis specialist either through facilitated telemedicine integrated into opioid treatment programs (n = 290) or standard-of-care off-site referral (n = 312). Main Outcomes and Measures: The primary outcome was hepatitis C virus cure. Twelve programs began with off-site referral, and every 9 months, 4 randomly selected sites transitioned to facilitated telemedicine during 3 steps without participant crossover. Participants completed 2-year follow-up for reinfection assessment. Inclusion criteria required 6-month enrollment in opioid treatment and insurance coverage of hepatitis C medications. Generalized linear mixed-effects models were used to test for the intervention effect, adjusted for time, clustering, and effect modification in individual-based intention-to-treat analysis. Results: Among 602 participants, 369 were male (61.3%); 296 (49.2%) were American Indian or Alaska Native, Asian, Black or African American, multiracial, or other (ie, no race category was selected, with race data collected according to the 5 standard National Institutes of Health categories); and 306 (50.8%) were White. The mean (SD) age of the enrolled participants in the telemedicine group was 47.1 (13.1) years; that of the referral group was 48.9 (12.8) years. In telemedicine, 268 of 290 participants (92.4%) initiated treatment compared with 126 of 312 participants (40.4%) in referral. Intention-to-treat cure percentages were 90.3% (262 of 290) in telemedicine and 39.4% (123 of 312) in referral, with an estimated logarithmic odds ratio of the study group effect of 2.9 (95% CI, 2.0-3.5; P < .001) with no effect modification. Observed cure percentages were 246 of 290 participants (84.8%) in telemedicine vs 106 of 312 participants (34.0%) in referral. Subgroup effects were not significant, including fibrosis stage, urban or rural participant residence location, or mental health (anxiety or depression) comorbid conditions. Illicit drug use decreased significantly (referral: 95% CI, 1.2-4.8; P = .001; telemedicine: 95% CI, 0.3-1.0; P < .001) among cured participants. Minimal reinfections (n = 13) occurred, with hepatitis C virus reinfection incidence of 2.5 per 100 person-years. Participants in both groups rated health care delivery satisfaction as high or very high. Conclusions and Relevance: Opioid treatment program-integrated facilitated telemedicine resulted in significantly higher hepatitis C virus cure rates compared with off-site referral, with high participant satisfaction. Illicit drug use declined significantly among cured participants with minimal reinfections. Trial Registration: ClinicalTrials.gov Identifier: NCT02933970.

RESUMEN

All-oral, direct-acting antivirals can cure hepatitis C virus (HCV) in almost all infected individuals; yet, many individuals with chronic HCV are not treated, and the incidence of acute HCV is increasing in some countries, including the United States. Strains on healthcare resources during the COVID-19 pandemic negatively impacted the progress toward the World Health Organization goal to eliminate HCV by 2030, especially among persons who inject drugs (PWID). Here, we present a holistic conceptual framework termed LOTUS (Leveraging Opportunities for Treatment/User Simplicity), designed to integrate the current HCV practice landscape and invigorate HCV treatment programs in the setting of endemic COVID-19: (A) treatment as prevention (especially among PWID), (B) recognition that HCV cure may be achieved with variable adherence with evidence supporting some forgiveness for missed doses, (C) treatment of all persons with active HCV infection (viremic), regardless of acuity, (D) minimal monitoring (MinMon) during treatment, and (E) rapid test and treat (TnT). The objective of this article is to review the current literature supporting each LOTUS petal; identify remaining gaps in knowledge or data; define the remaining barriers facing healthcare providers; and review evidence-based strategies for overcoming key barriers.

RESUMEN

BACKGROUND: Self-reported adherence to direct-acting antivirals (DAAs) to treat hepatitis C virus (HCV) among persons who inject drugs (PWID) is often an overreport of objectively measured adherence. The association of such overreporting with sustained virologic response (SVR) is understudied. This study among PWID aimed to determine a threshold of overreporting adherence that optimally predicts lower SVR rates, and to explore correlates of the optimal overreporting threshold. METHODS: This study analyzed per-protocol data of participants with adherence data (N = 493) from the HERO (Hepatitis C Real Options) study. Self-reported and objective adherence to a 12-week DAA regimen were measured using visual analogue scales and electronic blister packs, respectively. The difference (Δ) between self-reported and objectively measured adherence was calculated. We used the Youden index based on receiver operating characteristic (ROC) curve analysis to identify an optimal threshold of overreporting for predicting lower SVR rates. Factors associated with the optimal threshold of overreporting were identified by comparing baseline characteristics between participants at/above versus those below the threshold. RESULTS: The self-reported, objective, and Δ adherence averages were 95.1% (SD = 8.9), 75.9% (SD = 16.3), and 19.2% (SD = 15.2), respectively. The ≥ 25% overreporting threshold was determined to be optimal. The SVR rate was lower for ≥ 25% vs. < 25% overreporting (86.7% vs. 95.8%, p <.001). The factors associated with ≥ 25% Δ adherence were unemployment; higher number of days and times/day of injecting drugs; higher proportion of positive urine drug screening for amphetamine, methamphetamine, and oxycodone, and negative urine screening for THC (tetrahydrocannabinol)/cannabis. CONCLUSIONS: Self-reported DAA adherence was significantly greater than objectively measured adherence among PWID by 19.2%. Having ≥ 25% overreported adherence was associated with optimal prediction of lower SVR rates. PWID with risk factors for high overreporting may need to be more intensively managed to promote actual adherence.

RESUMEN

INTRODUCTION: Underutilization of hepatocellular cancer (HCC) surveillance has been reported, although data evaluating interventions to improve surveillance are sparse. We assessed the effect of a population-based HCC surveillance program on HCC surveillance utilization and outcomes. METHODS: In this retrospective cohort study, we assessed preinclusion and postinclusion HCC surveillance patterns among 597 patients with hepatitis C virus cirrhosis enrolled in a program at an integrated health system between 2013 and 2020. Adequate surveillance was defined as at least 5 surveillance studies within 36 months pre-enrollment and postenrollment; a secondary outcome was proportion of time covered by surveillance over 36 months. Tumor size, stage, and receipt of curative therapy were compared between HCC detected on the first imaging examination (prevalent HCC) and surveillance-detected HCC (incident HCC). We performed Kaplan-Meier analysis and multivariable competing risk analysis to characterize the association between surveillance and mortality. RESULTS: The surveillance program significantly improved surveillance completion (77.6% vs 5.0%, P < 0.001) and proportion time covered (80.9% vs 15.8%, P < 0.001). Compared with prevalent HCC, surveillance-detected cases were more likely unifocal (77.8% vs 44.8%, P < 0.001), early-stage (85.2% vs 44.8%, P < 0.001), with smaller maximum diameter (median 2.3 vs 3.2 cm), and more likely to undergo curative therapy (92.5% vs 72.4% P = 0.010). Survival was improved compared with prevalent cases hazard ratio (HR) 0.23 (0.11-0.51) after adjusting for age and Model for End Stage Liver Disease score. DISCUSSION: Implementation of a population-based program resulted in significant improvement in HCC surveillance use and clinical outcomes among patients with hepatitis C virus cirrhosis. These findings may inform similar interventions by other healthcare systems.

RESUMEN

OBJECTIVES: We examine how well ozone/oxygen gas therapy treats chronic hepatitis C patients with varying degrees of liver fibrosis. Also to study the effect of giving multiple anti-oxidants with the ozone/oxygen gas mixture, to see if this addition would have any additive or synergistic effect. METHODS: Two hundred and twenty three patients with chronic hepatitis C. Liver biopsies were carried out at after 12 weeks of administering an ozone/oxygen gas mixture. RESULTS: The mean stage of fibrosis decreased from 1.98 to 1.41 and the mean grade of inflammation decreased from 10.08 to 7.94, both with a p value less than 0.001. After 12 weeks of treatment, mean PCR values increased. No single significant complication was recorded in a total of >9,000 settings of ozone therapy. CONCLUSIONS: Ozone oxygen gas mixture is safe and effective in treatment of hepatic fibrosis due to chronic viral hepatitis C.

RESUMEN

BACKGROUND: Direct-acting antiviral (DAA) therapies for hepatitis C virus infection (HCV) lead to excellent rates of sustained virological response (SVR). However, loss to follow-up (LTFU) for SVR testing remains a challenge. We examine factors associated with LTFU in a real-world setting. METHODS: Adults who received DAA therapy for HCV in one of 26 centers across Australia during 2016-2021 were followed up for 2 years. Data sources included the patient medical records and the national Pharmaceutical and Medicare Benefits Schemes. Linkage to Medicare provided utilization data of other health-care providers and re-treatment with DAAs. LTFU was defined as no clinic attendance for SVR testing by at least 52 weeks after DAA treatment commencement. Multivariable logistic regression assessed factors associated with LTFU. RESULTS: In 3619 patients included in the study (mean age 52.0 years; SD = 10.5), 33.6% had cirrhosis (69.4% Child-Pugh class B/C), and 19.3% had HCV treatment prior to the DAA era. Five hundred and fifteen patients (14.2%) were LTFU. HCV treatment initiation in 2017 or later (adj-OR = 2.82, 95% confidence interval [CI] 2.25-3.54), younger age (adj-OR = 2.63, 95% CI 1.80-3.84), Indigenous identification (adj-OR = 1.99, 95% CI 1.23-3.21), current injection drug use or opioid replacement therapy (adj-OR = 1.66, 95% CI 1.25-2.20), depression treatment (adj-OR = 1.49, 95% CI 1.17-1.90), and male gender (adj-OR = 1.31, 95% CI 1.04-1.66) were associated with LTFU. CONCLUSIONS: These findings stress the importance of strengthening the network of providers caring for patients with HCV. In particular, services targeting vulnerable groups of patients such as First Nations Peoples, youth health, and those with addiction and mental health disorders should be equipped to treat HCV.

RESUMEN

Background/Aims: Chronic hepatitis C is a major risk factor for liver cirrhosis, hepatocellular carcinoma, and hepatic failure. Although traditional practices, including acupuncture, tend to increase the risk of HCV infection, the association remains controversial. Therefore, the current meta-analytical study was undertaken to evaluate the risks of acupuncture and hepatitis C transmission. Methods: Two researchers independently screened studies from the databases encompassing the period from inception to May 12, 2022. Baseline demographics, HCV transmission OR, and 95% CIs were extracted, pooled, and analyzed using random-effect models. Subgroup analyses utilizing study design and ethnicity were performed. Heterogeneity and publication bias were analyzed using the Higgins I2 test and funnel plots, respectively. Results: In all, 28 studies with 194,826 participants (178,583 controls [91.7%] vs. 16,243 acupuncture users [8.3%]) were included in the final analysis. The pooled analysis showed that acupuncture users had a significantly higher HCV transmission rate than controls with heterogeneity (OR, 1.84 [1.46-2.32]; p<0.001; I2 =80%). In the subgroup analysis, both cross-sectional case-control (n=14; OR, 1.96 [1.47-2.61]; p<0.001; I2 =88%) and cross-sectional studies (n=12; OR, 1.85 [1.32-2.61]; p<0.001; I2 =0%) showed significantly higher HCV infection rates in the acupuncture group than in the control group. Both Asian and non-Asian acupuncture users showed a higher HCV transmission risk than the controls (all Ps<0.001). No significant publication bias was observed. Conclusions: Our findings indicate that acupuncture increases the risk of HCV transmission. Due to HCV's contagiousness, unsafe medical and social practices (including acupuncture) should be performed with caution.

RESUMEN

Chronic hepatitis C virus (HCV) infection can lead to liver cirrhosis and hepatocellular carcinoma. Although current medications using direct-acting antivirals (DAAs) are highly effective and well-tolerated for treating patients with chronic HCV, high prices and the existence of DAA-resistant variants hamper treatment. There is thus a need for easily accessible antivirals with different mechanisms of action. During the screening of Indonesian medicinal plants for anti-HCV activity, we found that a crude extract of Dryobalanops aromatica leaves possessed strong antiviral activity against HCV. Bioassay-guided purification identified an oligostilbene, vaticanol B, as an active compound responsible for the anti-HCV activity. Vaticanol B inhibited HCV infection in a dose-dependent manner with 50% effective and cytotoxic concentrations of 3.6 and 559.5 µg/mL, respectively (Selectivity Index: 155.4). A time-of-addition study revealed that the infectivity of HCV virions was largely lost upon vaticanol B pretreatment. Also, the addition of vaticanol B following viral entry slightly but significantly suppressed HCV replication and HCV protein expression in HCV-infected and a subgenomic HCV replicon cells. Thus, the results clearly demonstrated that vaticanol B acted mainly on the viral entry step, while acting weakly on the post-entry step as well. Furthermore, co-treatment of the HCV NS5A inhibitor daclatasvir with vaticanol B increased the anti-HCV effect. Collectively, the present study has identified a plant-derived oligostilbene, vaticanol B, as a novel anti-HCV compound.

RESUMEN

Hepatitis C virus (HCV), a global malady, causes acute and chronic hepatitis leading to permanent liver damage, hepatocellular carcinoma, and death. Modern anti-HCV therapies are efficient, but mostly inaccessible for residents of underdeveloped regions. To innovate more effective treatments at affordable cost, medicinal plant-based products need to be explored. The aim of this article is to review plant constituents in the light of putative anti-HCV mechanisms of action, and discuss existing problems, challenges, and future directions for their potential application in therapeutic settings. One hundred sixty literatures were collected by using appropriate search strings via scientific search engines: Google Scholar, PubMed, ScienceDirect, and Scopus. Bibliography was prepared using Mendeley desktop software. We found a substantial number of plants that were reported to inhibit different stages of HCV life cycle. Traditional medicinal plants such as Phyllanthus amarus Schumach. and Thonn., Eclipta alba (L.) Hassk., and Acacia nilotica (L.) Delile exhibited strong anti-HCV activities. Again, several phytochemicals such as epigallocatechin-3-gallate, honokilol, punicalagin, and quercetin have shown broad-spectrum anti-HCV effect. We have presented promising phytochemicals like silymarin, curcumin, glycyrrhizin, and camptothecin for nanoparticle-based hepatocyte-targeted drug delivery. Nevertheless, only a few animal studies have been performed to validate the anti-HCV effect of these plant products. Again, insufficient clinical evaluation of the safety and effectiveness of herbal medications remain a problem. Selected plants products could be developed as novel therapeutics for HCV patients only after scrupulous evaluation of their safety and efficacy in a clinical set-up.

RESUMEN

INTRODUCTION: Hyperbaric chamber ventilation (HCV) refers to the intentional introduction of fresh gas, whether air, oxygen, or heliox, into a pressurised hyperbaric chamber in order to remove stale or otherwise compromised gas. The minimum required continuous HCV rate is usually determined by mathematical models derived from the contaminant mass balance within a well-stirred compartment. Non-uniform contaminant distribution patterns inside a hyperbaric chamber could emerge and invalidate the predictions of well-stirred models. METHODS: Contaminant distribution was investigated inside a clinical hyperbaric chamber with the aim of comparing well-stirred model predictions with the actual contaminant concentration measurements. RESULTS: Local ventilation effectiveness inside a clinical hyperbaric chamber may be compromised, leading to higher contaminant concentration values compared to the predictions of a mathematical model with a well-stirred assumption. CONCLUSIONS: A well-stirred assumption in mathematical models is a useful simplification that allows reasonably accurate estimates of HCV requirements. However, local ventilation effectiveness values in a particular hyperbaric chamber might vary, with the potential for hazardous contaminant accumulation in under-ventilated zones.

RESUMEN

INTRODUCTION: A vaccine against hepatitis C has not yet been developed. Recombinant proteins and plasmids encoding hepatitis C virus (HCV) proteins, the components of candidate vaccines, induce a weak immune response and require the use of adjuvants. The aim of the work was to study the adjuvant action of an aqueous solution of fullerene C60 during immunization of mice with HCV recombinant protein NS5B (rNS5B) that is an RNA-dependent RNA polymerase, or with NS5B-encoding pcNS5B plasmid. MATERIALS AND METHODS: An aqueous solution of dispersed fullerene (dnC60) was obtained by ultrafiltration. C57BL/6 mice were immunized with rNS5B subcutaneously, pcNS5B intramuscularly mixed with different doses of dnC60 three times, then the humoral and cellular response to HCV was evaluated. RESULTS: Mice immunization with rNS5B in a mixture with dnC60 at doses of 250 g/mouse significantly induced humoral response: a dose-dependent increase in IgG1 antibody titers was 720 times higher than in the absence of fullerene. There was no increase in the cellular response to rNS5B when administered with dnC60. The humoral response to DNA immunization was weak in mice of all groups receiving pcNS5B. The cellular response was suppressed when the plasmid was injected in a mixture with dnC60. CONCLUSIONS: Dispersed fullerene dnC60 is a promising adjuvant for increasing the immunostimulating activity of weakly immunogenic proteins including surface and other HCV proteins, important for a protective response. Further research is needed to enhance the ability of dnC60 to boost the cellular immune response to the components of the candidate vaccine.

RESUMEN

BACKGROUND: The Veterans Health Administration (VA) is the largest integrated healthcare organization in the US and cares for the largest cohort of individuals with hepatitis C (HCV). A national HCV population management dashboard enabled rapid identification and treatment uptake with direct acting antiviral agents across VA hospitals. We describe the HCV dashboard (HCVDB) and evaluate its use and user experience. METHODS: A user-centered design approach created the HCVDB to include reports based on the HCV care continuum: 1) 1945-1965 birth cohort high-risk screening, 2) linkage to care and treatment of chronic HCV, 3) treatment monitoring, 4) post-treatment to confirm cure (i.e., sustained virologic response), and 5) special populations of unstably housed Veterans. We evaluated frequency of usage and user experience with the System Usability Score (SUS) and Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) instruments. RESULTS: Between November 2016 and July 2021, 1302 unique users accessed the HCVDB a total of 163,836 times. The linkage report was used most frequently (71%), followed by screening (13%), sustained virologic response (11%), on-treatment (4%), and special populations (<1%). Based on user feedback (n = 105), the mean SUS score was 73±16, indicating a good user experience. Overall acceptability was high with the following UTAUT2 rated from highest to least: Price Value, Performance Expectancy, Social Influence, and Facilitating Conditions. CONCLUSIONS: The HCVDB had rapid and widespread uptake, met provider needs, and scored highly on user experience measures. Collaboration between clinicians, clinical informatics, and population health experts was essential for dashboard design and sustained use. Population health management tools have the potential for large-scale impacts on care timeliness and efficiency.

RESUMEN

Background: Opioid treatment programs are an essential component of the management of opioid use disorder (OUD). They have also been proposed as "medical homes" to expand health care access for underserved populations. We utilized telemedicine as a method to increase access for hepatitis C virus (HCV) care among people with OUD. Methods: We interviewed 30 staff and 15 administrators regarding the integration of facilitated telemedicine for HCV into opioid treatment programs. Participants provided feedback and insight for sustaining and scaling facilitated telemedicine for people with OUD. We utilized hermeneutic phenomenology to develop themes related to telemedicine sustainability in opioid treatment programs. Results: Three themes emerged on sustaining the facilitated telemedicine model: (1) Telemedicine as a Technical Innovation in Opioid Treatment Programs, (2) Technology Transcending Space and Time, and (3) COVID-19 Disrupting the Status Quo. Participants identified skilled staff, ongoing training, technology infrastructure and support, and an effective marketing campaign as key to maintaining the facilitated telemedicine model. Participants highlighted the study-supported case manager's role in managing the technology to transcend temporal and geographical challenges for HCV treatment access for people with OUD. COVID-19 fueled changes in health care delivery, including facilitated telemedicine, to expand the opioid treatment program's mission as a medical home for people with OUD. Conclusions: Opioid treatment programs can sustain facilitated telemedicine to increase health care access for underserved populations. COVID-19-induced disruptions promoted innovation and policy changes recognizing telemedicine's role in expanding health care access to underserved populations.

RESUMEN

Background: The World Health Organization has proposed to eliminate hepatitis C by 2030, yet there is still a large gap to the goal. Screening for hepatitis C is cost-effective and efficient in medical institutions. The aim of this study was to identify the key populations for HCV antibody screening in hospital characterized by infectious diseases, and provide estimates of the proportion of HCV-infected persons in the Beijing Ditan hospital completing each step along a proposed HCV treatment cascade. Methods: A total of 105,112 patients who underwent HCV antibody testing in Beijing Ditan hospital between 2017 and 2020 were included in this study. HCV antibody and HCV RNA positivity rate were calculated and compared by chi-square test. Results: The positivity rate of HCV antibody was 6.78%. The HCV antibody positivity rate and the proportion of positive patients showed an upward trend along with age in the five groups between 10-59 years. In the contrary, a decreasing trend was observed in the three groups above 60 years. Patients with positive HCV antibody were mainly from the Liver Disease Center (36.53%), the Department of Integrative Medicine (16.10%), the Department of Infectious Diseases (15.93%) and the Department of Obstetrics and Gynecology (9.44%). Among HCV antibody positive patients, 6,129 (85.95%) underwent further HCV RNA testing, of whom 2097 were HCV RNA positive, the positivity rate was 34.21%. Of the patients who were HCV RNA positive, 64.33% did not continue with HCV RNA testing. The cure rate for HCV antibody positive patients was 64.98%. Besides, there was a significant positive correlation between HCV RNA positivity rate and HCV antibody level (r = 0.992, P < 0.001). The detection rate of HCV antibody among inpatients showed an upward trend (Z = 5.567, P < 0.001), while the positivity rate showed a downward trend (Z = 2.2926, P = 0.0219). Conclusions: We found that even in hospitals characterized by infectious diseases, a large proportion of patients did not complete each step along a proposed HCV treatment cascade. Besides, we identified key populations for HCV antibody screening, namely: (1) patients over 40 years of age, especially those aged 50-59 years; (2) the Department of Infectious Diseases and the Department of Obstetrics and Gynecology patients. In addition, HCV RNA testing was highly recommended for patients with HCV antibody levels above 8 S/CO.

RESUMEN

OBJECTIVE: The hepatitis C virus (HCV) epidemic among gay, bisexual and other men who have sex with men (GBMSM) is associated with sexual and drug-related behaviours. To stem the tide of HCV infection in GBMSM, regular testing leading to early diagnosis and treatment as prevention is vital. This study aimed to evaluate the success of current HCV testing guidelines from the perspective of GBMSM in four Celtic nations. METHODS: Subpopulation analysis of data from the 2020 cross-sectional online SMMASH3 (social media, men who have sex with men, sexual and holistic health) survey was undertaken to examine HCV testing experiences and sexual behaviours among sexually active GBMSM (n=1886) stratified across three groups: HIV-diagnosed GBMSM (n=124); HIV-negative GBMSM using pre-exposure prophylaxis (PrEP) (n=365); and HIV-negative/untested GBMSM not using PrEP (n=1397). RESULTS: Sexual behaviours associated with HCV acquisition were reported by the majority of HIV-diagnosed (76.6%, n=95) and PrEP-using (93.2%, n=340) GBMSM. Reassuringly, recent testing for HCV in these groups was common, with 79.8% (n=99) and 80.5% (n=294) self-reporting HCV screening within the preceding year, respectively, mostly within sexual health settings. While 54.5% (n=762) of HIV-negative/untested GBMSM not using PrEP reported sexual behaviours associated with HCV, 52.0% had not been screened for HCV in the last year, despite almost half (48.0%, n=190) of unscreened men being in contact with sexual health services in the same period. CONCLUSIONS: Sexual behaviours associated with HCV acquisition among HIV-diagnosed and PrEP-using GBMSM are common but complemented by regular HCV testing within sexual health services. Current testing guidelines for these groups appear to be effective and generally well observed. However, behaviour-based HCV testing for HIV-negative/untested GBMSM not using PrEP appears less effective and may undermine efforts to achieve HCV elimination. Accordingly, we need to increase HCV testing for these men in clinical settings and explore ways to screen those who are not in touch with sexual health services.

RESUMEN

Branched chain amino acids (BCAA) supplementation may reduce the incidence of liver failure and hepatocellular carcinoma in patients with cirrhosis. We aimed to determine whether long-term dietary intake of BCAA is associated with liver-related mortality in a well-characterized cohort of North American patients with advanced fibrosis or compensated cirrhosis. We performed a retrospective cohort study using extended follow-up data from the Hepatitis C Antiviral Long-term Treatment against Cirrhosis (HALT-C) Trial. The analysis included 656 patients who completed two Food Frequency Questionnaires. The primary exposure was BCAA intake measured in grams (g) per 1000 kilocalories (kcal) of energy intake (range 3.0-34.8 g/1000 kcal). During a median follow-up of 5.0 years, the incidence of liver-related death or transplantation was not significantly different among the four quartiles of BCAA intake before and after adjustment of confounders (AHR 1.02, 95% CI 0.81-1.27, P-value for trend = 0.89). There remains no association when BCAA was modeled as a ratio of BCAA to total protein intake or as absolute BCAA intake. Finally, BCAA intake was not associated with the risk of hepatocellular carcinoma, encephalopathy or clinical hepatic decompensation. We concluded that dietary BCAA intake was not associated with liver-related outcomes in HCV-infected patients with advanced fibrosis or compensated cirrhosis. The precise effect of BCAA in patients with liver disease warrants further study.

RESUMEN

PURPOSE: American Indians/Alaska Native (AI/AN) persons are disproportionately affected by hepatitis C virus (HCV). The Northwest Portland Area Indian Health Board Indian Country Extension for Community Healthcare Outcomes (ECHO) telehealth clinic supports primary care providers (PCPs) in treating HCV. We evaluated the extent to which Indian Country ECHO increases access to HCV treatment and holistically serves AI/AN patients. METHODS: We conducted a retrospective descriptive analysis of Indian Country ECHO treatment recommendations from 2017 to 2021. Recommendations were classified into the following categories: HCV treatment with direct-acting antiviral medication, prevention, substance use disorder treatment, lab or imaging orders, pharmacological considerations, behavior changes, other, and referral. Subanalysis of treatment recommendations was completed for patients with cirrhosis. FINDINGS: Of the 776 patients from 77 Indian Health System facilities who presented at Indian Country ECHO, 718 (93%) received treatment recommendations. Most patients (93%) received recommendations for HCV treatment by their PCP; only 3% received a recommendation for referral to a hepatologist or liver transplant center for additional care. Most patients received at least 1 recommendation beyond the scope of HCV treatment provision. Cirrhosis criteria were met by 8% of patients, of which 80% received recommendations for HCV treatment by their PCP and 25% received recommendations for referral to a specialist for additional care. CONCLUSIONS: Most patients presented at the Indian Country ECHO received recommendations for HCV treatment by their PCP, along with recommendations beyond the scope of HCV. Indian Country ECHO telehealth clinic provides comprehensive recommendations to effectively integrate evidence-based HCV treatment with holistic care at the primary care level.

RESUMEN

Hepatitis C virus has a major role in spreading chronic liver disease and hepatocellular carcinoma. Factors such as high costs, pharmacological side effects, and the development of drug resistance strains require the development of new and potentially effective antiviral to treat the various stages of Hepatitis C. Bioactive chemicals have been extracted from medicinal plants and are utilized by humans for the goal of maintaining a healthy lifestyle. The goal of this work is to recognize phytochemicals from Eclipta alba and assess their potentiality activity against the hepatitis C virus envelope glycoprotein using in silico approaches. Phytochemicals from Eclipta alba were virtually screened by Auto dock raccoon and 12 compounds were selected for molecular docking to probe the active binding site. The top two compounds based on the binding score like ecliptalbine and oleanolic acid with HCV E2 glycoprotein exhibit binding energy -8.88 and -8.02 kcal/mol, respectively. The chemicals' usefulness was reinforced by positive pharmacokinetic data. The phytocompounds were identified as potent HCV inhibitors based on the drug likeness and ADMET properties. Both ecliptalbine and oleanolic acid underwent molecular dynamics simulations to determine features such as RMSD, RMSF, SASA, hydrogen-bond number, and MM-PBSA-based binding free energy. From the molecular docking and molecular dynamics simulation study revealed that oleanolic acid obtained from Eclipta alba can be used as inhibitors against Hepatitis C. The identified inhibitor from our study will be study in vitro and in vivo studies to check their efficacy against Hepatitis C.Communicated by Ramaswamy H. Sarma.

RESUMEN

Some biological therapies for psoriasis can cause the reactivation of viral infections. Although recent studies suggest no increased rate of reactivation with biological therapies, some life-threatening cases have been reported. Therefore, this meta-analysis examined the rate of virus reactivation in patients with psoriasis with biological therapies and concurrent hepatitis B virus (HBV), hepatitis C virus (HCV), or human immunodeficiency virus (HIV) infection. PubMed, Embase, and the Cochrane Library were searched for available papers from inception to December 2021. The outcome was the number of patients with virus reactivation after using biological therapies. The random-effect model was used in all analyses. Fourteen reports (1033 patients) were included. The pooled overall rate of virus reactivation was 0.04 (95%CI 0.01-0.09; I2 = 67.7%, P < 0.001). The pooled rates of HBV, HCV, and HIV reactivation were 0.04 (95%CI 0.00-0.10; I2 = 79.9%, P < 0.001), 0.07 (95%CI 0.02-0.14; I2 = 23.7%, P = 0.24), and 0.12 (95%CI 0.00-0.40), respectively. The pooled rates of HBV and HCV reactivation were 0.10 (95%CI 0.03-0.19) and 0.08 (95%CI 0.03-0.15) in Asia, but 0.00 (95%CI 0.00-0.01) and 0.04 (95%CI 0.00-0.21) in Europe. The publication type also influenced the results. The use of biological therapy in patients with psoriasis and HBV, HCV, or HIV infection might be associated with the rate of viral reactivation, but this meta-analysis had limitations, and the evidence might be weak. Nevertheless, it might suggest that at least a consultation with an infection specialist might be warranted in patients with psoriasis in whom biological therapies are considered.
