ABSTRACT
Incarcerated persons are infected with hepatitis C virus (HCV) at rates ≈10 times higher than that of the general population in the United States. To achieve national hepatitis C elimination goals, the diagnosis and treatment of hepatitis C in incarcerated persons must be prioritized. In 2022, the Centers for Disease Control and Prevention recommended that all persons receive opt-out HCV screening upon entry into a carceral setting. We review recommendations, treatments, and policy strategies used to promote HCV opt-out universal HCV screening and treatment in incarcerated populations in the United States. Treatment of hepatitis C in carceral settings has increased but varies by jurisdiction and is not sufficient to achieve HCV elimination. Strengthening universal HCV screening and treatment of HCV-infected incarcerated persons is necessary for HCV elimination nationwide.

New U.S. Centers for Disease Control and Prevention (CDC) guidelines for hepatitis C virus (HCV) testing of perinatally exposed infants and children released in 2023 recommend a nucleic acid test (NAT) for detection of HCV ribonucleic acid (i.e., NAT for HCV RNA) at 2-6 months of age to facilitate early identification and linkage to care for children with perinatally acquired HCV infection. Untreated hepatitis C can lead to cirrhosis, liver cancer, and premature death and is caused by HCV, a blood-borne virus transmitted most often among adults through injection drug use in the United States. Perinatal exposure from a birth parent with HCV infection is the most frequent mode of HCV transmission among infants and children. New HCV infections have been increasing since 2010, with the highest rates of infection among people aged 20-39 years, leading to an increasing prevalence of HCV infection during pregnancy. In 2020, the CDC recommended one-time HCV screening for all adults aged 18 years and older and for all pregnant persons during each pregnancy. Detecting HCV infection during pregnancy is key for the identification of pregnant persons, linkage to care for postpartum treatment, and identification of infants with perinatal exposure for HCV testing. It was previously recommended that children who were exposed to HCV during pregnancy receive an antibody to HCV (anti-HCV) test at 18 months of age; however, most children were lost to follow-up before testing occurred, leaving children with perinatal infection undiagnosed. The new strategy of testing perinatally exposed children at age 2-6 months was found to be cost-effective in increasing the identification of infants who might develop chronic hepatitis C. This report describes the current perinatal HCV testing recommendations and how they advance national hepatitis C elimination efforts by improving the health of pregnant and postpartum people and their children.

BACKGROUND: Estimated hepatitis C prevalence within the Veterans Health Administration is higher than the general population and is a risk factor for advanced liver disease and subsequent complications. We describe the hepatitis C care continuum within the Veterans Health Administration 1 January 2014 to 31 December 2022. METHODS: We included individuals in Veterans Health Administration care 2021-2022 who were eligible for direct-acting antiviral treatment 1 January 2014 to 31 December 2022. We evaluated the proportion of Veterans who progressed through each step of the hepatitis C care continuum, and identified factors associated with initiating direct-acting antivirals, achieving sustained virologic response, and repeat hepatitis C viremia. RESULTS: We identified 133 732 Veterans with hepatitis C viremia. Hepatitis C treatment was initiated in 107 134 (80.1%), with sustained virologic response achieved in 98 136 (91.6%). In those who achieved sustained virologic response, 1097 (1.1%) had repeat viremia and 579 (52.8%) were retreated for hepatitis C. Veterans of younger ages were less likely to initiate treatment and achieve sustained virologic response, and more likely to have repeat viremia. Stimulant use and unstable housing were negatively associated with each step of the hepatitis C care continuum. CONCLUSIONS: The Veterans Health Administration has treated 80% of Veterans with hepatitis C in care 2021-2022 and achieved sustained virologic response in more than 90% of those treated. Repeat viremia is rare and is associated with younger age, unstable housing, opioid use, and stimulant use. Ongoing efforts are needed to reach younger Veterans, and Veterans with unstable housing or substance use disorders.

Importance: Despite a lack of effectiveness data in humans, tecovirimat was widely prescribed to people with HIV (PWH) with mpox during the 2022 mpox epidemic, particularly PWH with low CD4+ T-cell counts or severe mpox clinical manifestations. Objective: To evaluate if PWH with mpox who were treated with tecovirimat within 7 days of symptom onset were less likely to have mpox disease progression. Design, Setting, and Participants: This cohort study included PWH diagnosed with mpox at 4 hospitals in Atlanta, Georgia, between June 1 and October 7, 2022. Patients were grouped according to whether they were treated with tecovirimat within 7 days of mpox symptom onset (early tecovirimat cohort) or they did not receive tecovirimat or received the drug 7 or more days after symptom onset (late or no tecovirimat cohort). Multivariable logistic regression models were used to identify factors associated with progression of mpox disease. The 2 cohorts were then matched 1:1 using propensity scores based on the identified factors, and mpox disease progression was compared. Exposures: Treatment with tecovirimat within 7 days of mpox symptom onset. Main Outcome and Measures: Progression of mpox disease, defined as the development of at least 1 severe mpox criterion established by the US Centers for Disease Control and Prevention, after symptom day 7. Results: After propensity score matching, a total of 112 PWH were included in the analysis; 56 received tecovirimat within 7 days of mpox symptom onset (early tecovirimat group) and 56 were either treated later or did not receive tecovirimat (late or no tecovirimat group). In the early tecovirimat group, the median (IQR) age was 35 (30-42) years; 54 individuals (96.4%) were cisgender men, 46 (82.1%) were Black individuals, and 10 (17.9%) were individuals of other races (American Indian or Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, or White) or unknown race. In the late or no tecovirimat group, the median (IQR) age was 36 (32-43) years; 54 (96.4%) were cisgender men, 49 (87.5%) were Black individuals, and 7 (12.5%) were individuals of other races or unknown race. Mpox disease progression occurred in 3 PWH (5.4%) in the early tecovirimat group and in 15 PWH (26.8%) in the late or no tecovirimat group (paired odds ratio, 13.00 [95% CI, 1.71-99.40]; P = .002). Conclusion and Relevance: Results of this cohort study support starting tecovirimat in all PWH as soon as an mpox diagnosis is suspected. Additional research is warranted to confirm these findings.

OBJECTIVE: Inpatient vaccination is an opportunity to increase vaccine uptake among patients at high risk for severe COVID-19 illness. We designed and implemented a hospital-based COVID-19 vaccination program with the aim of increasing documentation of vaccine eligibility and COVID-19 vaccination to eligible inpatients before discharge. METHODS: We integrated a templated note into the electronic medical records and trained health care personnel to screen inpatients and document COVID-19 vaccine eligibility at the Atlanta Veterans Affairs Medical Center. Vaccination staff deployed to inpatient wards administered the vaccine to eligible and consenting patients at the bedside. We calculated the number of inpatients whose vaccine eligibility was assessed and documented during a 4-week period after health care personnel were trained. We used the Wald χ2 test to compare the proportion of eligible patients who were vaccinated before discharge 4 weeks before (March 29-April 23, 2021) and 4 weeks after (May 3-28, 2021) the training period. RESULTS: During the 4 weeks before the training period, COVID-19 vaccine eligibility was not routinely assessed and documented. Of 793 inpatients discharged during the 4 weeks after the training period, 470 (59%) had COVID-19 vaccine eligibility documented. Of 86 patients who were eligible for vaccination, 61 (71%) received COVID-19 vaccination before discharge. COVID-19 vaccination rates during hospitalization increased significantly from 16 of 769 inpatients (2%) during the 4 weeks before training to 61 of 793 inpatients (8%) during the 4 weeks after training (P < .001). CONCLUSION: An inpatient vaccination program that integrated COVID-19 vaccination into discharge planning increased vaccine screening and uptake. Future studies are needed to identify barriers to vaccination and strategies to increase vaccine uptake among those who are hesitant.

BACKGROUND: In the Southeastern United States, the 2022 mpox outbreak disproportionately impacted people who are black and people with HIV (PWH). METHODS: We analyzed a cohort of 395 individuals diagnosed with mpox across 3 health care systems in Atlanta, Georgia between 1 June 2022 and 7 October 2022. We present demographic and clinical characteristics and use multivariable logistic regression analyses to evaluate the association between HIV status and severe mpox (per the US Centers for Disease Control and Prevention definition) and, among PWH, the associations between CD4+ T-cell count and HIV load with severe mpox. RESULTS: Of 395 people diagnosed with mpox, 384 (97.2%) were cisgender men, 335 (84.8%) identified as black, and 324 (82.0%) were PWH. Of 257 PWH with a known HIV load, 90 (35.0%) had > 200â copies/mL. Severe mpox occurred in 77 (19.5%) individuals and there was 1 (0.3%) death. Tecovirimat was prescribed to 112 (28.4%) people, including 56 (72.7%) people with severe mpox. In the multivariable analysis of the total population, PWH had 2.52 times higher odds of severe mpox (95% confidence interval [CI], 1.01-6.27) compared with people without HIV. In the multivariable analysis of PWH, individuals with HIV load > 200â copies/mL had 2.10 (95% CI, 1.00-4.39) times higher odds of severe mpox than PWH who were virologically suppressed. Lower CD4+ T-cell count showed a significant univariate association with severe mpox but was not found to be significantly associated with severe mpox in multivariable analysis. CONCLUSIONS: PWH with nonsuppressed HIV loads had more mpox complications, hospitalizations, and protracted disease courses than people without HIV or PWH with suppressed viral loads. PWH with nonsuppressed HIV loads who are diagnosed with mpox warrant particularly aggressive monitoring and treatment.

Importance: Some payers and clinicians require alcohol abstinence to receive direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection. Objective: To evaluate whether alcohol use at DAA treatment initiation is associated with decreased likelihood of sustained virologic response (SVR). Design, Setting, and Participants: This retrospective cohort study used electronic health records from the US Department of Veterans Affairs (VA), the largest integrated national health care system that provides unrestricted access to HCV treatment. Participants included all patients born between 1945 and 1965 who were dispensed DAA therapy between January 1, 2014, and June 30, 2018. Data analysis was completed in November 2020 with updated sensitivity analyses performed in 2023. Exposure: Alcohol use categories were generated using responses to the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) questionnaire and International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnoses for alcohol use disorder (AUD): abstinent without history of AUD, abstinent with history of AUD, lower-risk consumption, moderate-risk consumption, and high-risk consumption or AUD. Main Outcomes and Measures: The primary outcome was SVR, which was defined as undetectable HCV RNA for 12 weeks or longer after completion of DAA therapy. Multivariable logistic regression was used to estimate odds ratios (ORs) and 95% CIs of SVR associated with alcohol category. Results: Among 69â¯229 patients who initiated DAA therapy (mean [SD] age, 62.6 [4.5] years; 67â¯150 men [97.0%]; 34â¯655 non-Hispanic White individuals [50.1%]; 28â¯094 non-Hispanic Black individuals [40.6%]; 58â¯477 individuals [84.5%] with HCV genotype 1), 65â¯355 (94.4%) achieved SVR. A total of 32â¯290 individuals (46.6%) were abstinent without AUD, 9192 (13.3%) were abstinent with AUD, 13â¯415 (19.4%) had lower-risk consumption, 3117 (4.5%) had moderate-risk consumption, and 11â¯215 (16.2%) had high-risk consumption or AUD. After adjustment for potential confounding variables, there was no difference in SVR across alcohol use categories, even for patients with high-risk consumption or AUD (OR, 0.95; 95% CI, 0.85-1.07). There was no evidence of interaction by stage of hepatic fibrosis measured by fibrosis-4 score (P for interaction = .30). Conclusions and Relevance: In this cohort study, alcohol use and AUD were not associated with lower odds of SVR. Restricting access to DAA therapy according to alcohol use creates an unnecessary barrier to patients and challenges HCV elimination goals.

An estimated 2.4 million people in the United States are living with hepatitis C virus (HCV) infection. In 2020, the Centers for Disease Control and Prevention updated hepatitis C screening recommendations to test adults aged ≥ 18 years at least once in a lifetime and pregnant persons during each pregnancy. For those with ongoing exposure to HCV, periodic testing is recommended. The recommended testing sequence is to obtain an HCV antibody test and, when positive, perform an HCV RNA test. Examination of HCV care cascades has found incomplete HCV testing occurs when a separate visit is required to obtain the HCV RNA test. Hepatitis C core antigen (HCVcAg) testing has been shown to be a useful tool for diagnosing current HCV infection is some settings. Hepatitis C testing that is completed, accurate, and efficient is necessary to achieve hepatitis C elimination goals.
ABSTRACT
Current hepatitis C virus (HCV) testing guidance recommends a two-step testing sequence for diagnosis of HCV infection. Performing an HCV RNA test whenever an HCV antibody test is reactive (complete testing) is critical to achieve national HCV elimination goals. When an HCV antibody test is reactive and no HCV RNA test is performed, testing is considered incomplete. Historically, approximately one third of patients have incomplete testing. This update clarifies that all sites performing HCV screening should ensure single-visit sample collection. This approach allows for automatic HCV RNA testing when an HCV antibody test is reactive to avoid incomplete testing. Use of strategies that require multiple visits to collect HCV testing samples should be discontinued. Automatic HCV RNA testing on all HCV antibody reactive samples will increase the percentage of patients with current HCV infection who are linked to care and receive curative antiviral therapy.

To determine the hepatitis C virus (HCV) care cascade among persons who were born during 1945 to 1965 and received outpatient care on or after January 2014 at a large academic healthcare system. Deidentified electronic health record data in an existing research database were analyzed for this study. Laboratory test results for HCV antibody and HCV ribonucleic acid (RNA) indicated seropositivity and confirmatory testing. HCV genotyping was used as a proxy for linkage to care. A direct-acting antiviral (DAA) prescription indicated treatment initiation, an undetectable HCV RNA at least 20 weeks after initiation of antiviral treatment indicated a sustained virologic response. Of the 121,807 patients in the 1945 to 1965 birth cohort who received outpatient care between January 1, 2014 and June 30, 2017, 3399 (3%) patients were screened for HCV; 540 (16%) were seropositive. Among the seropositive, 442 (82%) had detectable HCV RNA, 68 (13%) had undetectable HCV RNA, and 30 (6%) lacked HCV RNA testing. Of the 442 viremic patients, 237 (54%) were linked to care, 65 (15%) initiated DAA treatment, and 32 (7%) achieved sustained virologic response. While only 3% were screened for HCV, the seroprevalence was high in the screened sample. Despite the established safety and efficacy of DAAs, only 15% initiated treatment during the study period. To achieve HCV elimination, improved HCV screening and linkage to HCV care and DAA treatment are needed.

To determine whether the Veterans Health Administration's (VHA) hepatitis C (HCV) treatment campaign reached marginalized populations, we compared HCV care by previous incarceration status with Veterans Aging Cohort Study data. Of those with and those without previous incarceration, respectively, 40% and 21% had detectable HCV, 59% and 65% underwent treatment (P = .07); 92% and 94% of those who completed treatment achieved sustained virologic response. The VHA HCV treatment effort was successful and other systems should replicate those efforts. (Am J Public Health. 2023;113(2):162-165. https://doi.org/10.2105/AJPH.2022.307152).

Background: Strategies for optimizing identification and outreach to potential candidates for monoclonal antibody (Mab) therapy for COVID-19 are not clear. Using a centralized, active surveillance system, the Atlanta Veterans Affairs Health Care System (AVAHCS) infectious disease (ID) team identified candidates for Mab infusion and provided treatment. Observations: As part of a quality improvement project from December 28, 2020, to August 31, 2021, a clinical team consisting of ID pharmacists and physicians reviewed each outpatient with a positive COVID-19 polymerase chain reaction test daily at the AVAHCS. The clinical team used Emergency Use Authorization (EUA) criteria to determine eligibility. Eligible patients were contacted on the same day of review via telephone to confirm eligibility and obtain verbal consent. Telehealth follow-up occurred on day 1 and day 7 postinfusion to assess for adverse events. In total, 2028 patients with COVID-19 were identified; 289 patients (14%) were eligible, and 132 (46%) received Mab therapy. Similar to AVAHCS demographics, a majority of those who received Mab therapy were non-Hispanic Black patients (65%). The most common comorbidities were hypertension (59%) and diabetes (37%). The median time from symptom onset to positive COVID-19 polymerase chain reaction (PCR) test result was 6 days (range, 0-9), and the median time from positive COVID-19 PCR test result to Mab infusion was 2 days (range, 0-8). Twelve patients (9%) required hospitalization for worsening COVID-19 symptoms postinfusion. No deaths occurred. Conclusions: Combining laboratory surveillance and active screening led to high uptake of Mab therapy and minimized delay from symptom onset to Mab infusion, thereby optimizing outpatient treatment of COVID-19. This approach also successfully screened and treated Black patients in the AVAHCS population.
ABSTRACT
Importance: Direct-acting antiviral (DAA) treatment for hepatitis C virus (HCV) infection is associated with lower mortality and is effective in individuals with alcohol use disorder (AUD). However, despite recommendations, patients with AUD may be less likely to receive DAAs. Objective: To assess the association between alcohol use and receipt of DAA treatment among patients with HCV within the Veterans Health Administration (VHA). Design, Setting, and Participants: This cohort study included 133â¯753 patients with HCV born from 1945 to 1965 who had completed the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) questionnaire and had at least 1 outpatient visit in the VHA from January 1, 2014, through May 31, 2017, with maximal follow-up of 3 years until May 31, 2020; DAA receipt; or death, whichever occurred first. Exposures: Alcohol use categories generated using responses to the AUDIT-C questionnaire and International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnoses: current AUD, abstinent with AUD history, at-risk drinking, lower-risk drinking, and abstinent without AUD history. Demographic, other clinical, and pharmacy data were also collected. Main Outcomes and Measures: Associations between alcohol use categories and DAA receipt within 1 and 3 years estimated using Cox proportional hazards regression stratified by calendar year. Results: Of 133â¯753 patients (130â¯103 men [97%]; mean [SD] age, 60.6 [4.5] years; and 73â¯493 White patients [55%]), 38% had current AUD, 12% were abstinent with a history of AUD, 6% reported at-risk drinking, 14% reported lower-risk drinking, and 30% were abstinent without a history of AUD. Receipt of DAA treatment within 1 year was 7%, 33%, 53%, and 56% for patients entering the cohort in 2014, 2015, 2016, and 2017, respectively. For patients entering in 2014, those with current AUD (hazard ratio [HR], 0.72 [95%, CI, 0.66-0.77]) or who were abstinent with an AUD history (HR, 0.91 [95% CI, 0.84-1.00]) were less likely to receive DAA treatment within 1 year compared with patients with lower-risk drinking. For those entering in 2015-2017, patients with current AUD (HR, 0.75 [95% CI, 0.70-0.81]) and those who were abstinent with an AUD history (HR, 0.76 [95% CI, 0.68-0.86]) were less likely to receive DAA treatment within 1 year compared with patients with lower-risk drinking. Conclusions and Relevance: This cohort study suggests that individuals with AUD, regardless of abstinence, were less likely to receive DAA treatment. Improved access to DAA treatment for persons with AUD is needed.

Treatment for hepatitis C virus (HCV) with direct-acting antivirals (DAA) is advantageous over previous treatment options due to high efficacy, short treatment duration, and relatively few drug interactions. Similarly, direct oral anticoagulants (DOAC) are generally preferred over warfarin for the management of thrombosis and atrial fibrillation due to a favourable safety profile. Direct-acting antivirals inhibit DOAC transport through P-glycoprotein inhibition leading to a theoretical increase in bleeding risk. We evaluated the incidence of bleeding in patients who received concurrent DAA and DOAC therapy and stratified the analysis based on the patient's cirrhosis status. We conducted a multicenter, retrospective cohort study to evaluate bleeding in patients with HCV and cirrhosis compared to patients with HCV without cirrhosis. Patients receiving at least 1 month of overlapping DAA and DOAC therapy between May 2017 and August 2020 at 11 medical centers in the United Kingdom and three medical centers in the United States were included. Charts were manually reviewed to identify baseline characteristics as well as thromboembolic or bleeding events. Bleeding events were categorized as major bleeding (MB) and clinically relevant non-major bleeding (CRNMB). Of 204 total patients, 36 patients (18%) had cirrhosis and 168 patients (82%) did not have cirrhosis. The majority of patients were male (79%) and Caucasian (75%). Sofosbuvir/velpatasvir (32%) and rivaroxaban (57%) were the most commonly prescribed DAA and DOAC, respectively. Leading indications for anticoagulation included thrombosis (75%) and atrial fibrillation (21%). There were three MB events (1.5%) all of which occurred in patients with additional risk factors (age over 65 and on antiplatelet therapy) and no CRNMB occurred while on DOAC and DAA therapy. Of the three MB, one occurred in a patient with cirrhosis and two in patients without cirrhosis, RR 1.23 (0.56-2.76). In conclusion, in this multicenter cohort study of concurrent DAA and DOAC use, MB was uncommon and there was no CRNMB. There was no significant difference in bleeding events among patients with cirrhosis compared to those without cirrhosis. These findings support the use of DAA among patients requiring DOAC.

OBJECTIVE: To compare the risk of coronavirus disease 2019 (COVID-19) outcomes by antiretroviral therapy (ART) regimens among men with HIV. DESIGN: We included men with HIV on ART in the Veterans Aging Cohort Study who, between February 2020 and October 2021, were 18âyears or older and had adequate virological control, CD4 + cell count, and HIV viral load measured in the previous 12âmonths, and no previous COVID-19 diagnosis or vaccination. METHODS: We compared the adjusted risks of documented severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, COVID-19-related hospitalization, and intensive care unit (ICU) admission by baseline ART regimen: tenofovir alafenamide (TAF)/emtricitabine (FTC), tenofovir disoproxil fumarate (TDF)/FTC, abacavir (ABC)/lamivudine (3TC), and other. We fit pooled logistic regressions to estimate the 18-month risks standardized by demographic and clinical factors. RESULTS: Among 20 494 eligible individuals, the baseline characteristics were similar across regimens, except that TDF/FTC and TAF/FTC had lower prevalences of chronic kidney disease and estimated glomerular filtration rate <60âml/min. Compared with TAF/FTC, the estimated 18-month risk ratio (95% confidence interval) of documented SARS-CoV-2 infection was 0.65 (0.43, 0.89) for TDF/FTC, 1.00 (0.85, 1.18) for ABC/3TC, and 0.87 (0.70, 1.04) for others. The corresponding risk ratios for COVID-19 hospitalization were 0.43 (0.07, 0.87), 1.09 (0.79, 1.48), and 1.21 (0.88, 1.62). The risk of COVID-19 ICU admission was lowest for TDF/FTC, but the estimates were imprecise. CONCLUSION: Our study suggests that, in men living with HIV, TDF/FTC may protect against COVID-19-related events. Randomized trials are needed to investigate the effectiveness of TDF as prophylaxis for, and early treatment of, COVID-19 in the general population.

HIV/hepatitis C virus (HCV) coinfection is a global health problem with overlapping modes of transmission. We performed a single-center retrospective case series of acute HCV infections at the Atlanta Veterans Affairs Health Care System between January 2001 and June 2020 to better characterize the presentation and clinical course of acute HCV among veterans with HIV. Cases were discovered through routine clinical care. We identified 29 cases of acute HCV: all men. Risk for HCV acquisition included men who have sex with men (MSM; 93%) and injection drug use (17%). Thirteen (45%) had a concurrent sexually transmitted infection (STI). Symptoms were seen in 76% of acute HCV cases and resulted in hospitalization in 59% of symptomatic cases. Seven (24%) presented as HCV antibody seronegative. Three never seroconverted, all with CD4 T cell counts <200. Spontaneous HCV clearance occurred in 21% (n = 6) and was more common in those who developed jaundice (p = 0.01). Time to treatment was significantly reduced in the direct-acting antivirals (DAAs) era versus the interferon era (300 vs. 1631 days, p < 0.01). Of those who did not spontaneously clear, 87% were treated (n = 20/23) and 95% (n = 19/20) achieved sustained virological response. Three patients died before HCV treatment, all in the pre-DAA period (one death was liver related). In this case series of acute HCV infection in persons with HIV, many were symptomatic MSM who had a concurrent STI, suggesting sexual HCV transmission. Some presented as HCV antibody negative, highlighting the role of enhanced HCV screening and treatment in MSM with HIV to prevent HCV transmission in sexual networks.

Automated identification systems may misidentify Brucella, the causative agent of brucellosis, which may be re-emerging in the United States as the result of an expanding feral swine population. We present a case of Brucella suis likely associated with feral swine exposure that was misidentified as Ochrobactrum anthropi, a phylogenetic relative.
ABSTRACT
BACKGROUND: Historically, older adults have been excluded from trials evaluating hepatitis C virus (HCV) treatment, in part, due to the adverse effects associated with previous regimens. Veterans are at high risk of HCV infection. Ledipasvir/sofosbuvir (LED/SOF) is a once daily antiviral regimen with demonstrated efficacy and tolerability among the younger population. We examined the tolerability and effectiveness of LED/SOF in Veterans age ≥65 years versus those <65 years who were treated at the Atlanta VA Health Care System (AVAHCS). METHODS: Using the VA Clinical Case Registry, all persons who filled a LED/SOF prescription at the AVAHCS from January 1, 2015, through March 31, 2016, were identified. The electronic medical records were reviewed to identify basic demographic information: comorbidities; polypharmacy; and outcomes. Sustained virologic response (SVR) was defined as an undetectable HCV RNA, at least 12 weeks after completing treatment. Descriptive statistics were employed using SAS v9.2. RESULTS: We identified 345 Veterans who filled LED/SOF during the study period; 94 were excluded due to exposure to ribavirin and IFN containing regimens; 97 (38.6%) were ≥65 years. Veterans were predominantly black (57%) and male (97%). Cancer was more prevalent among older Veterans (p = 0.047) as was polypharmacy (p = 0.001). Treatment completion rates between older and younger Veterans were not significantly different (99 vs. 95%, respectively; p = 0.16), but significantly more older Veterans achieved SVR (98 vs. 91%; p = 0.03). CONCLUSIONS: LED/SOF was a well-tolerated and effective regimen in an older Veteran population despite their multiple comorbidities and polypharmacy presence.

ABSTRACT: We assessed the performance characteristics of the Fibrosis-4 (FIB-4) score in a veteran population with chronic hepatitis C virus (HCV) infection and used vibration controlled transient elastography (VCTE) as the gold standard.All VCTE studies were performed by a single operator on United States veterans with HCV infection presenting for care at the Atlanta VA Medical Center (AVAMC) over a 2 year period. VCTE liver stiffness measurements (LSM) were categorized as cirrhotic if LSM was >12.5 kPa and non-cirrhotic if LSM was ≤12.5 kPa. FIB-4 scores ≤3.25 were considered non-cirrhotic and scores >3.25 were considered cirrhotic. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated for the FIB-4 score. A second analysis was done which identified and excluded indeterminate FIB-4 scores, defined as any value between 1.45 and 3.25.When FIB-4 was used to screen for liver cirrhosis using VCTE as the gold standard, sensitivity was 42%, specificity was 88%, PPV was 62%, and NPV was 76%. When indeterminate FIB-4 scores were excluded from the analysis, sensitivity was 95%, specificity was 61%, PPV was 62%, and NPV was 94.4%. In a veteran population with chronic HCV infection, we found the sensitivity of the FIB-4 score to be unacceptably low for ruling out liver cirrhosis when using a binary cutoff at 3.25. Using a second staging method like VCTE may be an effective way to screen for liver cirrhosis in persons with chronic HCV, especially when the FIB-4 score is in the indeterminate range.

BACKGROUND: Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfection is associated with accelerated progression to cirrhosis, end-stage liver disease, and liver-associated death. It is fortunate that curative direct-acting antivirals for the treatment of HCV are widely available in the VA healthcare system. We attempted to identify, evaluate, and treat all HIV/HCV-coinfected persons at the Atlanta VA Healthcare System. METHODS: Human immunodeficiency virus/HCV-coinfected persons at Atlanta VA between 2015 and 2018 were identified using the HIV Atlanta Veterans Affairs Cohort Study and Hepatitis C VA Clinical Case Registry. Retrospective reviews of each electronic medical record were conducted by the hepatitis C clinical team for validation. The primary end point was achieving sustained virologic response. RESULTS: One hundred thirty-eight veterans with HIV and hepatitis C viremia were identified. One hundred twenty-five (90%) were evaluated for treatment and 113 (91%) were initiated on direct-acting antiviral therapy. Median age at initiation of treatment was 60 years and the majority were black race (90%). Genotype 1a was most common (70%) and 41% had compensated cirrhosis. One hundred eight completed treatment and 96% achieved sustained virologic response. Six veterans had virologic relapse; 4 had treatment-emergent resistance mutations in the NS5a gene. Mean CD4 was 580 cells/mm3 with HIV viral suppression in 82% of the cohort. In those not treated, unstable housing (25%), active substance use (31%), and psychiatric conditions (42%) were identified barriers to care. CONCLUSIONS: Through a concerted, systematic effort, over 80% of HIV/hepatitis C persons in the Atlanta VA have been initiated on treatment for hepatitis C, 96% of which have been cured.
