J Infect Dis 2023 228 (6) 684-693 BACKGROUND: The country of Georgia initiated its hepatitis C virus (HCV) elimination program in 2015, at which point a serosurvey showed the adult prevalence of HCV antibody (anti-HCV) and HCV RNA to be 7.7% and 5.4%, respectively. This analysis reports hepatitis C results of a follow-up serosurvey conducted in 2021, and progress towards elimination. METHODS: The serosurvey used a stratified, multistage cluster design with systematic sampling to include adults and children (aged 5-17 years) providing consent (or assent with parental consent). Blood samples were tested for anti-HCV and if positive, HCV RNA. Weighted proportions and 95% confidence intervals (CI) were compared with 2015 age-adjusted estimates. RESULTS: Overall, 7237 adults and 1473 children were surveyed. Among adults, the prevalence of anti-HCV was 6.8% (95% CI, 5.9-7.7). The HCV RNA prevalence was 1.8% (95% CI, 1.3-2.4), representing a 67% reduction since 2015. HCV RNA prevalence decreased among those reporting risk factors of ever injecting drugs (51.1% to 17.8%), and ever receiving a blood transfusion (13.1% to 3.8%; both P < .001). No children tested positive for anti-HCV or HCV RNA. CONCLUSIONS: These results demonstrate substantial progress made in Georgia since 2015. These findings can inform strategies to meet HCV elimination targets. |

Euro Surveill 2023 28 (30) BackgroundGeorgia has adopted the World Health Organization European Region's and global goals to eliminate viral hepatitis. A nationwide serosurvey among adults in 2015 showed 2.9% prevalence for hepatitis B virus (HBV) surface antigen (HBsAg) and 25.9% for antibodies against HBV core antigen (anti-HBc). HBV infection prevalence among children had previously not been assessed.AimWe aimed to assess HBV infection prevalence among children and update estimates for adults in Georgia.MethodsThis nationwide cross-sectional serosurvey conducted in 2021 among persons aged ≥ 5 years used multi-stage stratified cluster design. Participants aged 5-20 years were eligible for hepatitis B vaccination as infants. Blood samples were tested for anti-HBc and, if positive, for HBsAg. Weighted proportions and 95% confidence intervals (CI) were calculated for both markers.ResultsAmong 5-17 year-olds (n = 1,473), 0.03% (95% CI: 0-0.19) were HBsAg-positive and 0.7% (95% CI: 0.3-1.6) were anti-HBc-positive. Among adults (n = 7,237), 2.7% (95% CI: 2.3-3.4) were HBsAg-positive and 21.7% (95% CI: 20.4-23.2) anti-HBc-positive; HBsAg prevalence was lowest (0.2%; 95% CI: 0.0-1.5) among 18-23-year-olds and highest (8.6%; 95% CI: 6.1-12.1) among 35-39-year-olds.ConclusionsHepatitis B vaccination in Georgia had remarkable impact. In 2021, HBsAg prevalence among children was well below the 0.5% hepatitis B control target of the European Region and met the ≤ 0.1% HBsAg seroprevalence target for elimination of mother-to-child transmission of HBV. Chronic HBV infection remains a problem among adults born before vaccine introduction. Screening, treatment and preventive interventions among adults, and sustained high immunisation coverage among children, can help eliminate hepatitis B in Georgia by 2030. |

Walker JG , Tskhomelidze I , Shadaker S , Tsereteli M , Handanagic S , Armstrong PA , Gamkrelidze A , Vickerman P . Euro Surveill 2023 28 (30) BackgroundBetween May 2015 and February 2022, 77,168 hepatitis C virus (HCV)-infected people in Georgia have been treated through an HCV elimination programme. To project the programme's long-term impacts, an HCV infection model was initially developed, based on data from surveys among people who inject drugs and a national serosurvey in 2015.AimAccounting for follow-up surveys in 2021, we validate and update projections of HCV infection prevalence and incidence.MethodWe assessed the initial model projections' accuracy for overall prevalence, by age, sex, and among people who ever injected drugs, compared with 2021 serosurvey data. We used 2021 results to weight model fits and to recalculate the national programme's impact leading up to March 2022 on HCV infection incidence rates. Cases and deaths averted were estimated. The impact of reduced treatment rates during the COVID-19 pandemic was assessed.ResultsThe original model overpredicted adult (≥ 18 years old) chronic HCV infection prevalence for 2021 (2.7%; 95% credible interval (CrI): 1.9-3.5%) compared with a 2021 serosurvey (1.8%; 95% confidence interval (CI): 1.3-2.4%). Weighted model projections estimated a 60% decrease in HCV infection incidence by March 2022, with an absolute incidence of 66 (95% CrI: 34-131) per 100,000 person-years (overall population). Between May 2015 and March 2022, 9,186 (95% CrI: 5,396-16,720) infections and 842 (95% CrI: 489-1,324) deaths were averted. The COVID-19 pandemic resulted in 13,344 (95% CrI: 13,236-13,437) fewer treatments and 438 (95% CrI: 223-744) fewer averted infections by March 2022.ConclusionResults support the programme's high effectiveness. At current treatment rate (406/month), 90% reductions in prevalence and incidence in Georgia are achievable by 2030. |

In April 2015, the Georgian government, in collaboration with CDC and other partners, launched a national program to eliminate HCV through scaling up HCV treatment and prevention interventions, with the aim of achieving a 90% reduction in prevalence by 2020. We evaluate the interim impact of the HCV treatment program as of 31 October 2017, and assess the feasibility of achieving the elimination goal by 2020.Method We developed a dynamic HCV transmission model to capture the current and historical epidemic dynamics of HCV in Georgia, including the main drivers of transmission. Using the 2015 national sero-survey and prior surveys conducted among people who inject drugs (PWID) from 1997-2015, the model was calibrated to data on HCV prevalence by age, gender and PWID status, and the age distribution of PWID. We use the model to project the interim impact of treatment strategies currently being undertaken as part of the ongoing Georgia HCV elimination program, while accounting for treatment failure/loss to follow up, in order to determine whether they are on track to achieving their HCV elimination target by 2020, or whether strategies need to be modified to ensure success.Results A treatment rate of 2,050 patients/month was required from the beginning of the national program to achieve a 90% reduction in prevalence by the end of 2020, with equal treatment rates of PWID and the general population. From May 2015 to October 2017, 40,420 patients were treated, an average of ~1,350 per month; although the treatment rate has recently declined from a peak of 4,500/month in September 2016 to 2100/month in November-December 2016, and 1000/month in August-October 2017, with a sustained virological response rate (SVR) of 98% per-protocol or 78% intent to treat. The model projects that the treatments undertaken up to October 2017 have reduced adult chronic prevalence by 26% (18-35%) to 3.7% (2.9-5.1%), reduced total incidence by 25% (15-35%), and prevented 1845 (751-3969) new infections and 93 (31-177) HCV-related deaths. If the treatment rate of 1000 patients initiated per month continues, prevalence will have halved by 2020, and reduce by 90% by 2026. In order to reach a 90% reduction by 2020, the treatment rate must increase 3.5-fold to 4000/month.Conclusion The Georgia HCV elimination program has accomplished an impressive scale up of treatment, which has already impacted on prevalence and incidence, and averted deaths due to HCV. However, extensive scale up is needed to achieve a 90% reduction in prevalence by 2020. |

Clin Infect Dis 2023 77 (3) 405-413 BACKGROUND: Mortality related to hepatitis C virus (HCV) infection is a key indicator for elimination. We assessed the impact of HCV infection and treatment on mortality in the country of Georgia during 2015-2020. METHODS: We conducted a population-based cohort study using data from Georgia's national HCV Elimination Program and death registry. We calculated all-cause mortality rates in six cohorts: 1) Negative for anti-HCV; 2) anti-HCV positive, unknown viremia status; 3) current HCV infection and untreated; 4) discontinued treatment; 5) completed treatment, no SVR assessment; 6) completed treatment and achieved SVR. Cox proportional hazards models were used to calculate adjusted hazards ratios and confidence intervals. We calculated the cause-specific mortality rates attributable to liver-related causes. RESULTS: After a median follow-up of 743 days, 100,371 (5.7%) of 1,764,324 study participants died. The highest mortality rate was observed among HCV infected patients who discontinued treatment (10.62 deaths per 100 PY, 95%CI: 9.65, 11.68), and untreated group (10.33 deaths per 100 PY, 95%CI: 9.96, 10.71). In adjusted Cox proportional hazards model, the untreated group had almost six-times higher hazard of death compared to treated groups with or without documented SVR (aHR=5.56, 95%CI: 4.89, 6.31). Those who achieved SVR had consistently lower liver-related mortality compared to cohorts with current or past exposure to HCV. CONCLUSION: This large population-based cohort study demonstrated the marked beneficial association between hepatitis C treatment and mortality. The high mortality rates observed among HCV infected and untreated persons highlights the need to prioritize linkage to care and treatment to achieve elimination goals. |
Advancing blood transfusion safety using molecular detection in the country of Georgia
Alkhazashvili M , Bloch EM , Shadaker S , Kuchuloria T , Getia V , Turdziladze A , Armstrong PA , Gamkrelidze A . Transfus Clin Biol 2023 30 (3) 307-313 BACKGROUND: In 2015, the country of Georgia initiated its hepatitis C virus (HCV) elimination program. Given a high background incidence of HCV infection, centralized nucleic acid testing (NAT) of blood donations was prioritized for implementation. STUDY DESIGN AND METHODS: Multiplex NAT screening for HIV, HCV and hepatitis B virus (HBV) was launched in January 2020. An analysis was conducted of serological and NAT donor/donation data for the first year of screening (through December 2020). RESULTS: A total of 54,116 donations representing 39,164 unique donors were evaluated. Overall, 671 donors (1.7%) tested positive for at least one infectious marker by serology or NAT, with the highest prevalence among donors aged 40-49 years (2.5%; n=200), male (1.9%; n=524), replacement (2.8%; n=153) and first time (2.1%; n=642) donors. Sixty donations were seronegative but NAT positive, and therefore would not have been found by traditional serology testing alone. These were more likely among female vs. male (adjusted odds ratio [aOR] 2.06; 95% confidence interval [95%CI]: 1.05-4.05), paid (aOR 10.15; 95%CI: 2.80-36.86) or voluntary (aOR 4.30; 95%CI: 1.27-14.56) vs replacement, and repeat vs. first time (aOR 13.98; 95%CI: 4.06-48.12) donors. On repeat serological testing (including HBV core antibody [HBcAb] testing), 6 HBV+ donations, 5 HCV+ donations and 1 HIV+ donations were deemed NAT yield (detected through the implementation of NAT, and would have otherwise been missed by serology screening alone). CONCLUSION: This analysis offers a regional model for NAT implementation, demonstrating the feasibility and clinical utility in a nationwide blood program. |
Economic evaluation of the hepatitis C virus elimination program in the country of Georgia, 2015 to 2017

Liver Int 2022 43 (3) 558-568 BACKGROUND AND AIMS: In 2015, the country of Georgia launched an elimination program aiming to reduce prevalence of Hepatitis C virus (HCV) infection by 90% from 5.4% prevalence (~150,000 people). During the first 2.5 years of the program, 770,832 people were screened, 48,575 were diagnosed with active HCV infection, and 41,483 patients were treated with direct-acting antiviral (DAA) based regimens, with >95% cure rate. METHODS: We modelled the incremental cost-effectiveness ratio (ICER) of HCV screening, diagnosis, and treatment between April 2015 and November 2017 compared to no treatment, in terms of cost per quality-adjusted life year (QALY) gained in 2017 US dollars, with 3% discount rate over 25 years. We compared the ICER to willingness-to-pay (WTP) thresholds of US$4357 (GDP) and US$871 (opportunity-cost) per QALY gained. RESULTS: The average cost of screening, HCV viremia testing, and treatment per patient treated was $386 to the provider, $225 to the patient, and $1042 for generic DAAs. At 3% discounting, 0.57 QALYs were gained per patient treated. The ICER from the perspective of the provider including generic DAAs was $2,285 per QALY gained, which is cost-effective at the $4357 WTP threshold, while if patient costs are included it's just above the threshold at $4,398/QALY. All other scenarios examined in sensitivity analyses remain cost-effective except for assuming a shorter time horizon to end of 2025, or including list price DAA cost. Reducing or excluding DAA costs reduced the ICER below the opportunity-cost WTP threshold. CONCLUSIONS: The Georgian HCV elimination program provides valuable evidence that national programs for scaling up HCV screening and treatment for achieving HCV elimination can be cost-effective. |
The impact of COVID-19 pandemic on the 2020 hepatitis C cascade of care in the Republic of Georgia.
Gamkrelidze A , Handanagic S , Shadaker S , Turdziladze A , Tsereteli M , Getia V , Aslanikashvili A , Surguladze S , Gvinjilia L , Kuchuloria T , Tskhomelidze I , Armstrong PA . Public Health 2022 205 182-186 OBJECTIVES: In 2015, the Republic of Georgia initiated a National Hepatitis C Elimination Program, with a goal of 90% reduction in prevalence of chronic hepatitis C virus (HCV) infections by 2020. In this article, we explore the impact of the COVID-19 pandemic on the 2020 hepatitis C cascade of care in Georgia. STUDY DESIGN: Retrospective analytic study. METHODS: We used a national screening registry that includes hospitals, blood banks, antenatal clinics, harm reduction sites, and other programs and services to collect data on hepatitis C screening. A separate national treatment database was used to collect data on viremia and diagnostic testing, treatment initiation, and outcome including testing for and achieving sustained virologic response (SVR). We used these databases to create hepatitis C care cascades for 2020 and 2019. Bivariate associations for demographic characteristics and screening locations per year and care cascade comparisons were assessed using a chi-squared test. RESULTS: In 2020 compared to 2019, the total number of persons screened for HCV antibodies decreased by 25% (from 975,416 to 726,735), 59% fewer people with viremic infection were treated for HCV infection (3188 vs. 7868), 46% fewer achieved SVR (1345 vs. 2495), a significantly smaller percentage of persons with viremic infection initiated treatment for HCV (59% vs. 62%), while the percentage of persons who achieved SVR (99.2% vs. 99.3%) remained stable. CONCLUSIONS: The COVID-19 pandemic had a negative impact on the hepatitis C elimination program in Georgia. To ensure Georgia reaches its elimination goals, mitigating unintended consequences of delayed diagnosis and treatment of hepatitis C due to the COVID-19 pandemic are paramount. |

J Med Screen 2022 29 (2) 9691413221086497 OBJECTIVES: Georgia has a high prevalence of hepatitis C virus (HCV) infection. In 2015 a national HCV elimination program was launched providing free access to screening and treatment. To achieve elimination, innovative approaches to increase screening coverage and linkage to care are needed. This study estimates feasibility, acceptability, and outcomes of the door-to-door pilot HCV testing program in three cities. METHODS: Households were approached by system random sampling and all members were invited for study participation. Researchers used a detailed guide for conducting door-to-door testing and served as case navigators to link anti-HCV-positive individuals to care. RESULTS: Testing acceptance rate was high. In total 4804 individuals were tested and 48 (1.0%) were HCV positive. Among the entire sample of newly and previously tested individuals, overall HCV antibody prevalence was 3.6%. Through case navigation, of 48 newly identified and 26 previously identified anti-HCV-positive individuals, 42 (87.5%) and 17 (65.4%), respectively, were successfully linked to care. CONCLUSIONS: Door-to-door HCV testing has potential to increase testing uptake. Such community-based approaches not only improve testing, but can also serve to increase linkage to care, which is important in achieving the goal of HCV elimination. The study provides a model for high prevalence countries aiming to eliminate hepatitis C. |

Liver Int 2022 42 (4) 775-786 BACKGROUND AND AIMS: In 2015, Georgia began a hepatitis C virus (HCV) elimination programme. Although screening programmes have been decentralised for high-risk groups, viraemic testing remains a bottleneck for people who inject drugs. Here, we describe two models of viraemic testing that aimed to address this gap. METHODS: We assigned eight harm reduction sites (HRS) to one of three arms (2:1:1): Xpert HCV viral load testing on-site, blood draw on-site with centralised HCV core antigen testing (HCVcAg), or standard-of-care (SOC) referral with viremia testing performed at treatment centres. RESULTS: 1671 HCV-seropositive participants were enrolled (Xpert, 37·1%; HCVcAg, 29·1%; referral, 33·8%). Participants were predominantly male (95·4%), mean age (IQR) 43 (37, 50) years, and 1290 (77·2%) were currently injecting drugs. Significantly higher proportions of participants in the Xpert (100%) and HCVcAg (99·8%) arms received viraemia testing compared with the referral arm (91·3%) (Xpert vs referral, p<0·0001; HCVcAg vs referral, p<0·0001). Among viraemic participants, treatment uptake was similar (Xpert, 84·0%; HCVcAg, 79·5%; referral, 88·4%). The time between screening and sample collection for viraemia testing was significantly longer in the referral arm compared with both Xpert and HCVcAg arms (median 1 day compared with 0 days, respectively), and the overall time between screening to treatment initiation was longer for the referral arm (median 67 days) compared with both Xpert and HCVcAg arms (median 57 and 50 days, respectively). CONCLUSIONS: Point-of-care viraemia testing and blood drawn on-site for HCVcAg testing yielded more HCV-seropositive patients receiving viraemic testing within a shorter timeframe compared with referrals. |

PLoS One 2022 17 (1) e0262935 In preparation for the National Hepatitis C Elimination Program in the country of Georgia, a nationwide household-based hepatitis C virus (HCV) seroprevalence survey was conducted in 2015. Data were used to estimate HCV genotype distribution and better understand potential sex-specific risk factors that contribute to HCV transmission. HCV genotype distribution by sex and reported risk factors were calculated. We used explanatory logistic regression models stratified by sex to identify behavioral and healthcare-related risk factors for HCV seropositivity, and predictive logistic regression models to identify additional variables that could help predict the presence of infection. Factors associated with HCV seropositivity in explanatory models included, among males, history of injection drug use (IDU) (aOR = 22.4, 95% CI = 12.7, 39.8) and receiving a blood transfusion (aOR = 3.6, 95% CI = 1.4, 8.8), and among females, history of receiving a blood transfusion (aOR = 4.0, 95% CI 2.1, 7.7), kidney dialysis (aOR = 7.3 95% CI 1.5, 35.3) and surgery (aOR = 1.9, 95% CI 1.1, 3.2). The male-specific predictive model additionally identified age, urban residence, and history of incarceration as factors predictive of seropositivity and were used to create a male-specific exposure index (Area under the curve [AUC] = 0.84). The female-specific predictive model had insufficient discriminatory performance to support creating an exposure index (AUC = 0.61). The most prevalent HCV genotype (GT) nationally was GT1b (40.5%), followed by GT3 (34.7%) and GT2 (23.6%). Risk factors for HCV seropositivity and distribution of HCV genotypes in Georgia vary substantially by sex. The HCV exposure index developed for males could be used to inform targeted testing programs. |

Kasradze A , Shadaker S , Kuchuloria T , Gamkrelidze A , Nasrullah M , Gvinjilia L , Baliashvili D , Chitadze N , Kodani M , Tejada-Strop A , Drobeniuc J , Hagan L , Morgan J , Imnadze P , Averhoff F . Public Health 2020 185 341-347 OBJECTIVES: The burden of hepatitis B virus (HBV) and hepatitis D virus (HDV) infections is unknown in Georgia. This analysis describes the prevalence of hepatitis B and coinfection with HDV and the demographic characteristics and risk factors for persons with HBV infection in Georgia. STUDY DESIGN: This is a cross-sectional seroprevalence study. METHODS: A cross-sectional, nationwide survey to assess hepatitis B prevalence among the general adult Georgian population (age ≥18 years) was conducted in 2015. Demographic and risk behavior data were collected. Blood specimens were screened for anti-hepatitis B core total antibody (anti-HBc). Anti-HBc-positive specimens were tested for hepatitis B surface antigen (HBsAg). HBsAg-positive specimens were tested for HBV and HDV nucleic acid. Nationally weighted prevalence estimates and adjusted odds ratios (aORs) for potential risk factors were determined for anti-HBc and HBsAg positivity. RESULTS: The national prevalence of anti-HBc and HBsAg positivity among adults were 25.9% and 2.9%, respectively. Persons aged ≥70 years had the highest anti-HBc positivity (32.7%), but the lowest HBsAg positivity prevalence (1.3%). Anti-HBc positivity was associated with injection drug use (aOR = 2.34; 95% confidence interval [CI] = 1.46-3.74), receipt of a blood transfusion (aOR = 1.68; 95% CI = 1.32-2.15), and sex with a commercial sex worker (aOR = 1.46; 95% CI = 1.06-2.01). HBsAg positivity was associated with receipt of a blood transfusion (aOR = 2.72; 95% CI = 1.54-4.80) and past incarceration (aOR = 2.72; 95% CI = 1.25-5.93). Among HBsAg-positive persons, 0.9% (95% CI = 0.0-2.0) were HDV coinfected. CONCLUSIONS: Georgia has an intermediate to high burden of hepatitis B, and the prevalence of HDV coinfection among HBV-infected persons is low. Existing infrastructure for hepatitis C elimination could be leveraged to promote hepatitis B elimination. |
High sustained viral response among HCV genotype 3 patients with advanced liver fibrosis: real-world data of HCV elimination program in Georgia.
Butsashvili M , Gvinjilia L , Kamkamidze G , Metreveli D , Dvali S , Rukhadze T , Gamkrelidze A , Nasrullah M , Shadaker S , Morgan J , Averhoff F . BMC Res Notes 2020 13 (1) 332 OBJECTIVE: In 2015, Georgia launched HCV elimination program. Initially, patients with advanced liver disease were treated with sofosbuvir-based regimen-the only DAA available for all genotypes. Purpose of the study was assessing real-world data of treatment outcome among patients with HCV GEN3 and advanced liver fibrosis with sofosbuvir-based regimens. RESULTS: Totally 1525 genotype 3 patients were eligible for analysis; most (72.6%) were aged > 45 years, majority were males (95.1%), and all (100%) had advanced liver disease (F3 or F4 by METAVIR score based on elastography). Of those who received sofosbuvir/ribavirin (SOF/RBV) for 24 weeks, 79.3% achieved SVR, while 96.5% who received sofosbuvir/pegylated interferon/ribavirin (SOF/PEG/RBV) for 12 weeks achieved SVR (p < 0.01). Among patients with liver cirrhosis (defined as F4) overall cure rate was 85.7% as opposed to 96.4% for those with F3. Females were more likely to be cured (98.7% vs 89.7%; OR = 8.54). Patients aged 31-45 years had higher likelihood of achieving SVR compared to patients aged 46-60 years (95.7% vs 87.4%; OR = 0.32,). Independent predictors of SVR were treatment with SOF/PEG/RBV (aOR = 6.72) and lower fibrosis stage (F3) (aOR = 4.18). Real-world experience among HCV GEN3 patients with advanced liver fibrosis and treated by sofosbuvir regimen w/o PEGIFN, demonstrated overall high SVR rate. |

Transfusion 2020 60 (6) 1243-1252 BACKGROUND: In April 2015, the government of Georgia (country) initiated the worldʼs first national hepatitis C elimination program. An analysis of blood donor infectious screening data was conducted to inform a strategic plan to advance blood transfusion safety in Georgia. STUDY DESIGN AND METHODS: Descriptive analysis of blood donation records (2015-2017) was performed to elucidate differences in demographics, donor type, remuneration status, and seroprevalence for infectious markers (hepatitis C virus antibody [anti-HCV], human immunodeficiency virus [HIV], hepatitis B virus surface antigen [HBsAg], and Treponema pallidum). For regression analysis, final models included all variables associated with the outcome in bivariate analysis (chi-square) with a p value of less than 0.05. RESULTS: During 2015 to 2017, there were 251,428 donations in Georgia, representing 112,093 unique donors; 68.5% were from male donors, and 51.2% of donors were paid or replacement (friends or family of intended recipient). The overall seroprevalence significantly declined from 2015 to 2017 for anti-HCV (2.3%-1.4%), HBsAg (1.5%-1.1%), and T. pallidum (1.1%-0.7%) [p < 0.0001]; the decline was not significant for HIV (0.2%-0.1%). Only 41.0% of anti-HCV seropositive donors underwent additional testing to confirm viremia. Infectious marker seroprevalence varied by age, sex, and geography. In multivariable analysis, first-time and paid donor status were associated with seropositivity for all four infectious markers. CONCLUSION: A decline during the study period in infectious markers suggests improvement in blood safety in Georgia. Areas that need further improvement are donor recruitment, standardization of screening and diagnostic follow-up, quality assurance, and posttransfusion surveillance. |

Prev Med 2020 138 106153 The country of Georgia initiated an ambitious national hepatitis C elimination program. To facilitate elimination, a national hospital hepatitis C screening program was launched in November 2016, offering all inpatients screening for HCV infection. This analysis assesses the effectiveness of the first year of the screening program to identify HCV-infected persons and link them to care. Data from Georgia's electronic Health Management Information System and ELIMINATION-C treatment database were analyzed for patients aged >/=18 years hospitalized from November 1, 2016 to October 31, 2017. We described patient characteristics and screening results and compared linked-to-care patients to those not linked to care, defined as having a test for viremia following an HCV antibody (anti-HCV) positive hospital screening. Of 291,975 adult inpatients, 252,848 (86.6%) were screened. Of them, 4.9% tested positive, with a high of 17.4% among males aged 40-49. Overall, 19.8% of anti-HCV+ patients were linked to care, which differed by sex (20.6% for males vs. 18.4% for females; p = .019), age (23.9% for age 50-59 years vs. 10.7% for age >/= 70 years; p < .0001), and length of hospitalization (21.8% among patients hospitalized for 1 day vs. 16.1% for those hospitalized 11+ days; p = .023). Redundant screening is a challenge; 15.6% of patients were screened multiple times and 27.6% of anti-HCV+ patients had a prior viremia test. This evaluation demonstrates that hospital-based screening programs can identify large numbers of anti-HCV+ persons, supporting hepatitis C elimination. However, low linkage-to-care rates underscore the need for screening programs to be coupled with effective linkage strategies. |

BMC Infect Dis 2020 20 (1) 30 BACKGROUND: Georgia has one of the highest HCV prevalence in the world and launched the world's first national HCV elimination programs in 2015. Georgia set the ambitious target of diagnosing 90% of people living with HCV, treating 95% of those diagnosed and curing 95% of treated patients by 2020. We report outcomes of Sofosbuvir (SOF) based treatment regimens in patients with chronic HCV infection in Georgia. METHODS: Patients with cirrhosis, advanced liver fibrosis and severe extrahepatic manifestations were enrolled in the treatment program. Initial treatment consisted of SOF plus ribavirin (RBV) with or without pegylated interferon (INF). Sustained virologic response (SVR) was defined as undetectable HCV RNA at least 12 weeks after the end of treatment. SVR were calculated using both per-protocol and modified intent-to-treat (mITT) analysis. Results for patients who completed treatment through 31 October 2018 were analyzed. RESULTS: Of the 7342 patients who initiated treatment with SOF-based regimens, 5079 patients were tested for SVR. Total SVR rate was 82.1% in per-protocol analysis and 74.5% in mITT analysis. The lowest response rate was observed among genotype 1 patients (69.5%), intermediate response rate was achieved in genotype 2 patients (81.4%), while the highest response rate was among genotype 3 patients (91.8%). Overall, SOF/RBV regimens achieved lower response rates than IFN/SOF/RBV regimen (72.1% vs 91.3%, P < 0.0001). In multivariate analysis being infected with HCV genotype 2 (RR =1.10, CI [1.05-1.15]) and genotype 3 (RR = 1.14, CI [1.11-1.18]) were associated with higher SVR. Patients with cirrhosis (RR = 0.95, CI [0.93-0.98]), receiving treatment regimens of SOF/RBV 12 weeks, SOF/RBV 20 weeks, SOF/RBV 24 weeks and SOF/RBV 48 weeks (RR = 0.85, CI [0.81-0.91]; RR = 0.86, CI [0.82-0.92]; RR = 0.88, CI [0.85-0.91] and RR = 0.92, CI [0.87-0.98], respectively) were less likely to achieve SVR. CONCLUSIONS: Georgia's real world experience resulted in high overall response rates given that most patients had severe liver damage. Our results provide clear evidence that SOF plus IFN and RBV for 12 weeks can be considered a treatment option for eligible patients with all three HCV genotypes. With introduction of next generation DAAs, significantly improved response rates are expected, paving the way for Georgia to achieve HCV elimination goals. |

Lancet Glob Health 2019 8 (2) e244-e253 BACKGROUND: Georgia has a high prevalence of hepatitis C, with 5.4% of adults chronically infected. On April 28, 2015, Georgia launched a national programme to eliminate hepatitis C by 2020 (90% reduction in prevalence) through scaled-up treatment and prevention interventions. We evaluated the interim effect of the programme and feasibility of achieving the elimination goal. METHODS: We developed a transmission model to capture the hepatitis C epidemic in Georgia, calibrated to data from biobehavioural surveys of people who inject drugs (PWID; 1998-2015) and a national survey (2015). We projected the effect of the administration of direct-acting antiviral treatments until Feb 28, 2019, and the effect of continuing current treatment rates until the end of 2020. Effect was estimated in terms of the relative decrease in hepatitis C incidence, prevalence, and mortality relative to 2015 and of the deaths and infections averted compared with a counterfactual of no treatment over the study period. We also estimated treatment rates needed to reach Georgia's elimination target. FINDINGS: From May 1, 2015, to Feb 28, 2019, 54 313 patients were treated, with approximately 1000 patients treated per month since mid 2017. Compared with 2015, our model projects that these treatments have reduced the prevalence of adult chronic hepatitis C by a median 37% (95% credible interval 30-44), the incidence of chronic hepatitis C by 37% (29-44), and chronic hepatitis C mortality by 14% (3-30) and have prevented 3516 (1842-6250) new infections and averted 252 (134-389) deaths related to chronic hepatitis C. Continuing treatment of 1000 patients per month is predicted to reduce prevalence by 51% (42-61) and incidence by 51% (40-62), by the end of 2020. To reach a 90% reduction by 2020, treatment rates must increase to 4144 (2963-5322) patients initiating treatment per month. INTERPRETATION: Georgia's hepatitis C elimination programme has achieved substantial treatment scale-up, which has reduced the burden of chronic hepatitis C. However, the country is unlikely to meet its 2020 elimination target unless treatment scales up considerably.

J Hepatol 2019 72 (4) 680-687 BACKGROUND & AIMS: Georgia, with a high prevalence of hepatitis C virus (HCV) infection, launched the world's first national hepatitis C elimination program in April 2015. A key strategy is the identification, treatment, and cure of the estimated 150,000 HCV infected persons living in the country. We report on progress and key challenges from Georgia's experience. METHODS: We constructed a care cascade by analyzing linked data from the national hepatitis C screening registry and treatment databases during 2015-2018. We assessed the impact of reflex hepatitis C core antigen (HCVcAg) testing on rates of viremia testing and treatment initiation (i.e. linkage to care). RESULTS: As of December 31, 2018, 1,101,530 adults (39.6% of the adult population) were screened for HCV antibody, of whom 98,430 (8.9%) tested positive, 78,484 (79.7%) received viremia testing, of these, 66,916 persons (85.3%) tested positive for active HCV infection. A total of 52,576 persons with active HCV infection initiated treatment, 48,879 completed their course of treatment. Of the 35,035 who were tested for cure (i.e., sustained virologic response [SVR]), 34,513 (98.5%) achieved SVR. Reflex HCVcAg testing, implemented in March 2018, increased rates of monthly viremia testing among persons screening positive for anti-HCV by 97.5%, however, rates of treatment initiation decreased by 60.7% among diagnosed viremic patients. CONCLUSIONS: Over one-third of persons living with HCV in Georgia have been detected and linked to care and treatment, however, identification and linkage to care of the remaining persons with HCV infection is challenging. Novel interventions, such as reflex testing with HCVcAg can improve rates of viremia testing, but may result in unintended consequences, such as decreased rates of treatment initiation. Linked data systems allow for regular review of the care cascade, allowing for identification of deficiencies and development of corrective actions. |

Clin Infect Dis 2019 71 (5) 1263-1268 BACKGROUND: In April 2015, in collaboration with U.S. CDC and Gilead Sciences, Georgia embarked on the world's first hepatitis C elimination program. We aimed to assess progress towards elimination targets after three years since the beginning of the elimination program. METHODS: We constructed an HCV care cascade for adults in Georgia, based on the estimated 150,000 persons age >/= 18 years with active HCV infection. All patients who were screened or entered the treatment program during April 2015 - March 2018 were included in the analysis. Data on the number of persons screened for HCV was extracted from the national HCV screening database. For treatment component we utilized data from the Georgia National HCV treatment program database. Available treatment options included sofosbuvir (SOF) and ledipasvir/sofosbuvir (LDV/SOF) based regimens. RESULTS: Since April 2015, a cumulative 974,817 adults were screened for HCV antibodies, 86,624 persons tested positive, of which 61,925 underwent HCV confirmatory testing. Among estimated 150,000 adults living with chronic hepatitis C in Georgia, 52,856 (35.1%) were diagnosed, 45,334 (30.2%) initiated treatment with DAA, and 29,090 (19.4%) achieved sustained virologic response (SVR). Overall 37,256 persons were eligible for SVR assessment, of these only 29,620 (79.5%) returned for evaluation. In the per-protocol analysis, SVR rate achieved was 98.2% (29,090/29,620), and 78.1% (29,090/37,256) in the intent-to-treat analysis. CONCLUSIONS: Georgia has made substantial progress in the path towards eliminating hepatitis C. Scaling-up testing and diagnosis, along with effective linkage to treatment services are needed to achieve the goal of elimination. |
Excellence in viral hepatitis elimination - lessons from Georgia

J Hepatol 2019 71 (4) 645-647 Globally, there are more than 70 million people living with chronic hepatitis C virus (HCV) infection, and an estimated 257 million people are living with hepatitis B virus (HBV) infection, both of which cause significant morbidity and mortality primarily as consequences of chronic infection, including hepatocellular carcinoma and liver failure.1 Georgia, a small country in the South Caucasus, has a high prevalence of HCV infection with an estimated 150,000 adults living with hepatitis C, representing 5.4% of the adult population.2 Georgia was the first country in the world to undertake the challenge of hepatitis C elimination. A serosurvey in 2015 laid the foundation for the elimination program; the survey not only defined the burden of hepatitis C in the country, but also identified the major risk factors for transmission (injection drug use and receipt of blood products) and the demographic profile of those infected, thus allowing for clear characterization of the epidemic including identifying the most at-risk populations.2 The cost of treatment in 2015 was prohibitive, so a key partnership was established with Gilead Sciences, who agreed to support the elimination program by providing free-of-charge treatment directly to the country because of the government's commitment to hepatitis C elimination nationwide. |
Progress in testing for and treatment of hepatitis C virus infection among persons who inject drugs - Georgia, 2018
Stvilia K , Spradling PR , Asatiani A , Gogia M , Kutateladze K , Butsashvili M , Zarkua J , Tsertsvadze T , Sharvadze L , Japaridze M , Kuchuloria T , Gvinjilia L , Tskhomelidze I , Gamkrelidze A , Khonelidze I , Sergeenko D , Shadaker S , Averhoff F , Nasrullah M . MMWR Morb Mortal Wkly Rep 2019 68 (29) 637-641 In April 2015, the country of Georgia, with a high prevalence of hepatitis C virus (HCV) infection (5.4% of the adult population, approximately 150,000 persons), embarked on the world's first national elimination program (1,2). Nearly 40% of these infections are attributed to injection drug use, and an estimated 2% of the adult population currently inject drugs, among the highest prevalence of injection drug use in the world (3,4). Since 2006, needle and syringe programs (NSPs) have been offering HCV antibody testing to persons who inject drugs and, since 2015, referring clients with positive test results to the national treatment program. This report summarizes the results of these efforts. Following implementation of the elimination program, the number of HCV antibody tests conducted at NSPs increased from an average of 3,638 per year during 2006-2014 to an average of 21,551 during 2015-2018. In 2017, to enable tracking of clinical outcomes among persons who inject drugs, NSPs began encouraging clients to voluntarily provide their national identification number (NIN), which all citizens must use to access health care treatment services. During 2017-2018, a total of 2,780 NSP clients with positive test results for HCV antibody were identified in the treatment database by their NIN. Of 494 who completed treatment and were tested for HCV RNA >/=12 weeks after completing treatment, 482 (97.6%) were cured of HCV infection. Following the launch of the elimination program, Georgia has made much progress in hepatitis C screening among persons who inject drugs; recent data demonstrate high cure rates achieved in this population. Testing at NSPs is an effective strategy for identifying persons with HCV infection. Tracking clients referred from NSPs through treatment completion allows for monitoring the effectiveness of linkage to care and treatment outcomes in this population at high risk, a key to achieving hepatitis C elimination in Georgia. The program in Georgia might serve as a model for other countries. |

BMC Public Health 2019 19 480 Background: The country of Georgia launched the world's first Hepatitis C Virus (HCV) Elimination Program in 2015 and set a 90% prevalence reduction goal for 2020. We conducted a nationally representative HCV seroprevalence survey to establish baseline prevalence to measure progress toward elimination over time. Methods: A cross-sectional seroprevalence survey was conducted in 2015 among adults aged ≥18 years using a stratified, multi-stage cluster design (n = 7000). Questionnaire variables included demographic, medical, and behavioral risk characteristics and HCV-related knowledge. Blood specimens were tested for antibodies to HCV (anti-HCV) and HCV RNA. Frequencies were computed for HCV prevalence, risk factors, and HCV-related knowledge. Associations between anti-HCV status and potential risk factors were calculated using logistic regression. Results: National anti-HCV seroprevalence in Georgia was 7.7% (95% confidence interval (CI) = 6.7, 8.9); HCV RNA prevalence was 5.4% (95% CI = 4.6, 6.4). Testing anti-HCV+ was significantly associated with male sex, unemployment, urban residence, history of injection drug use (IDU), incarceration, blood transfusion, tattoos, frequent dental cleanings, medical injections, dialysis, and multiple lifetime sexual partners. History of IDU (adjusted odds ratio (AOR) = 21.4, 95% CI = 12.3, 37.4) and blood transfusion (AOR = 4.5, 95% CI = 2.8, 7.2) were independently, significantly associated with testing anti-HCV+ after controlling for sex, age, urban vs. rural residence, and history of incarceration. Among anti-HCV+ participants, 64.0% were unaware of their HCV status, and 46.7% did not report IDU or blood transfusion as a risk factor. Conclusions: Georgia has a high HCV burden, and a majority of infected persons are unaware of their status. Ensuring a safe blood supply, implementing innovative screening strategies beyond a risk-based approach, and intensifying prevention efforts among persons who inject drugs are necessary steps to reach Georgia's HCV elimination goal. |
The global campaign to eliminate HBV and HCV infection: International Viral Hepatitis Elimination Meeting and core indicators for development towards the 2030 elimination goals

J Virus Erad 2019 5 (1) 60-66 Hepatitis B virus (HBV) and hepatitis C virus (HCV) affect more than 320 million people worldwide, which is more than HIV, tuberculosis (TB) and malaria combined. Elimination of HBV and HCV will, therefore, produce substantial public health and economic benefits and, most importantly, the prevention of 1.2 million deaths per year. In 2016, member states of the World Health Assembly unanimously adopted a resolution declaring that viral hepatitis should be eliminated by 2030. Currently, few countries have elimination programmes in place and even though the tools to achieve elimination are available, the right resources, commitments and allocations are lacking. During the fifth International Viral Hepatitis Elimination Meeting (IVHEM), 7-8 December 2018, Amsterdam, the Netherlands, an expert panel of clinicians, virologists and public health specialists discussed the current status of viral hepatitis elimination programmes across multiple countries, challenges in achieving elimination and the core indicators for monitoring progress, approaches that have failed and successful elimination plans. |
The role of screening and treatment in national progress toward hepatitis C elimination - Georgia, 2015-2016

MMWR Morb Mortal Wkly Rep 2017 66 (29) 773-776 Georgia, a country in the Caucasus region of Eurasia, has a high prevalence of hepatitis C virus (HCV) infection. In April 2015, with technical assistance from CDC, Georgia embarked on the world's first program to eliminate hepatitis C, defined as a 90% reduction in HCV prevalence by 2020 (1,2). The country committed to identifying infected persons and linking them to care and curative antiviral therapy, which was provided free of charge through a partnership with Gilead Sciences (1,2). From April 2015 through December 2016, a total of 27,595 persons initiated treatment for HCV infection, among whom 19,778 (71.7%) completed treatment. Among 6,366 persons tested for HCV RNA ≥12 weeks after completing treatment, 5,356 (84.1%) had no detectable virus in their blood, indicative of a sustained virologic response (SVR) and cure of HCV infection. The number of persons initiating treatment peaked in September 2016 at 4,595 and declined during October-December. Broader implementation of interventions that increase access to HCV testing, care, and treatment for persons living with HCV are needed for Georgia to reach national targets for the elimination of HCV. |
HCV elimination - lessons learned from a small Eurasian country, Georgia
Nasrullah M , Sergeenko D , Gamkrelidze A , Averhoff F . Nat Rev Gastroenterol Hepatol 2017 14 (8) 447-448 In April 2015, in partnership with the US Centers for Disease Control and Prevention and Gilead Sciences, the country of Georgia launched the world's first national HCV elimination programme, aiming to reduce HCV prevalence by 90% by 2020. After 2 years of progress, how can the Georgia experience inform global approaches to eliminating HCV? | In May 2016, the World Health Assembly endorsed the Global Health Sector Strategy on Viral Hepatitis 2016–2021, which calls for the elimination of viral hepatitis as a public health threat by 2030 (a 90% reduction in new infections caused by HBV and HCV infections and a 65% reduction in deaths from these infections)1. An estimated 71 million people have HCV globally, resulting in ∼400,000 deaths annually; most mortality is caused by hepatocellular carcinoma and end-stage liver disease2. The WHO estimates that 1.75 million new HCV infections occurred worldwide in 2015, with wide variations in incidence; transmission mode also varies by country, but the most common modes globally are associated with unsafe health-care practices, followed by injection drug use2. |
Launch of a nationwide hepatitis C elimination program - Georgia, April 2015

MMWR Morb Mortal Wkly Rep 2015 64 (28) 753-7 Hepatitis C virus (HCV) infects an estimated 130-150 million persons globally and results in an estimated 700,000 deaths annually from hepatocellular carcinoma or cirrhosis. Georgia, a middle-income Eurasian country, has one of the highest estimated HCV prevalences in the world. In 2011, Georgia began offering treatment to a limited number of HCV-infected persons. Beginning in 2013, when new oral medications that can cure >90% of HCV infections were licensed, Georgia engaged partners to develop a comprehensive HCV prevention and control plan, during which the concept of elimination of HCV transmission and disease emerged. To prepare for the launch of an HCV elimination program, Georgia requested CDC's assistance to describe HCV epidemiology, evaluate laboratory and health care capacity, and conduct program monitoring and evaluation. This report describes the activities undertaken to prepare for the program, launched in April 2015, and early results of its initial phase, focused on improving access to affordable diagnostics and free curative treatment for HCV-infected persons with severe liver disease. A national population-based serosurvey began in May 2015, and four clinical sites and their laboratories were selected as initial pilot sites; since June, three additional sites have been added. Through July 3, 2015, a total of 6,491 persons sought treatment, and 6,177 (95.2%) initiated diagnostic work-up. Among these, 1,519 (24.6%) completed work-up, 1,474 (97.0%) of whom initiated treatment. Georgia is scaling up capacity to meet the demand for HCV treatment and is collaborating with CDC and other partners on development of a comprehensive HCV elimination plan that includes specific goals and activities needed to achieve them. |
