ABSTRACT
Despite cancer being a leading comorbidity amongst individuals with HIV, there are limited data assessing cancer trends across different antiretroviral therapy (ART)-eras. We calculated age-standardised cancer incidence rates (IRs) from 2006-2021 in two international cohort collaborations (D:A:D and RESPOND). Poisson regression was used to assess temporal trends, adjusted for potential confounders. Amongst 64,937 individuals (31% ART-naïve at baseline) and 490,376 total person-years of follow-up (PYFU), there were 3763 incident cancers (IR 7.7/1000 PYFU [95% CI 7.4, 7.9]): 950 AIDS-defining cancers (ADCs), 2813 non-ADCs, 1677 infection-related cancers, 1372 smoking-related cancers, and 719 BMI-related cancers (groups were not mutually exclusive). Age-standardised IRs for overall cancer remained fairly constant over time (8.22/1000 PYFU [7.52, 8.97] in 2006-2007, 7.54 [6.59, 8.59] in 2020-2021). The incidence of ADCs (3.23 [2.79, 3.72], 0.99 [0.67, 1.42]) and infection-related cancers (4.83 [4.2, 5.41], 2.43 [1.90, 3.05]) decreased over time, whilst the incidence of non-ADCs (4.99 [4.44, 5.58], 6.55 [5.67, 7.53]), smoking-related cancers (2.38 [2.01, 2.79], 3.25 [2.63-3.96]), and BMI-related cancers (1.07 [0.83, 1.37], 1.88 [1.42, 2.44]) increased. Trends were similar after adjusting for demographics, comorbidities, HIV-related factors, and ART use. These results highlight the need for better prevention strategies to reduce the incidence of NADCs, smoking-, and BMI-related cancers.
ABSTRACT
BACKGROUND: There are conflicting data regarding baseline determinants of virological nonsuppression outcomes in persons with human immunodeficiency virus (HIV) starting antiretroviral treatment (ART). We evaluated the impact of different baseline variables in the RESPOND cohort. METHODS: We included treatment-naive participants aged ≥18 who initiated 3-drug ART, in 2014-2020. We assessed the odds of virological suppression (VS) at weeks 48 and 96 using logistic regression. Viral blips, low-level viremia (LLV), residual viremia (RV), and virological failure (VF) rates were assessed using Cox regression. RESULTS: Of 4310 eligible participants, 72% started integrase strand transfer inhibitor (INSTI)-based regimens. At 48 and 96 weeks, 91.0% and 93.3% achieved VS, respectively. At 48 weeks, Kaplan-Meier estimates of rates were 9.6% for viral blips, 2.1% for LLV, 22.2% for RV, and 2.1% for VF. Baseline HIV-1 RNA levels >100 000 copies/mL and CD4+ T-cell counts ≤200/µL were negatively associated with VS at weeks 48 (adjusted odds ratio, 0.51 [95% confidence interval, .39-.68] and .40 [.27-.58], respectively) and 96 and with significantly higher rates of blips, LLV, and RV. CD4+ T-cell counts ≤200/µL were associated with higher risk of VF (adjusted hazard ratio, 3.12 [95% confidence interval, 2.02-4.83]). Results were consistent in those starting INSTIs versus other regimens and those starting dolutegravir versus other INSTIs. CONCLUSIONS: Initial high HIV-1 RNA and low CD4+ T-cell counts are associated with lower rates of VS at 48 and 96 weeks and higher rates of viral blips, LLV, and RV. Low baseline CD4+ T-cell counts are associated with higher VF rates. These associations remain with INSTI-based and specifically with dolutegravir-based regimens. These findings suggest that the impact of these baseline determinants is independent of the ART regimen initiated.

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 6 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 sustained virologic response (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% confidence interval [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 6-times higher hazard of death compared to treated groups with or without documented SVR (adjusted hazard ratio [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. CONCLUSIONS: 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.

OBJECTIVES: Georgia introduced remdesivir for the treatment of COVID-19 in December 2020. We evaluated the real-world effect of remdesivir on mortality and the need for mechanical ventilation among inpatients with COVID-19. METHODS: The study included 346 remdesivir recipients and 346 controls not receiving remdesivir selected through propensity score matching based on age, gender, presence of any chronic comorbid condition, and oxygen saturation at admission. Factors associated with in-hospital mortality and the need for mechanical ventilation were assessed in a multivariable logistic regression model. RESULTS: The groups were comparable by age, gender, comorbidities, and baseline oxygen saturation. Among 346 remdesivir recipients, 265 (76.6%) received a generic formulation of the drug. Eight (2.3%) patients died in the remdesivir group and 18 (5.2%) in the control group (P = 0.046). In the multivariable analysis, remdesivir was associated with non-statistically significant reduced odds of death (odds ratio: 0.39, 95% confidence interval: 0.14-1.04, P = 0.06). Significantly fewer patients in the remdesivir group required mechanical ventilation compared to controls: 2.9% vs 6.4% (P = 0.03). Statistically significant difference was maintained in multivariable analysis (odds ratio: 0.40, 95% confidence interval: 1.04-5.60, P = 0.04). CONCLUSION: Borderline reduction in the odds of death and statistically significant decrease in the need for mechanical ventilation support use of remdesivir in hospitalized patients with COVID-19.

OBJECTIVES: Our objective was to determine whether antiretroviral drugs (ARVs) were used according to the European AIDS Clinical Society (EACS) guidelines for people with HIV/hepatitis C virus (HCV) coinfection treated with direct-acting antivirals (DAAs) between 30 November 2014 and 31 December 2019 in the pan-European EuroSIDA study. METHODS: At each publication date of the EACS guidelines, plus 3 and 6 months, we calculated the number of people receiving DAAs with potential and actual ARV contraindications ('red shading' in the EACS guidelines). We used logistic regression to investigate factors associated with using contraindicated ARVs. RESULTS: Among 1406 people starting DAAs, the median age was 51 years, 75% were male, 57% reported injected drug use as an HIV risk, and 76% were from western Europe. Of 1624 treatment episodes, 609 (37.5%) occurred while the patient was receiving ARVs with potential contraindications; among them, 38 (6.2%; 95% confidence interval [CI] 4.3-8.2) involved a contraindicated ARV (18 non-nucleoside reverse transcriptase inhibitors), 16 involved protease inhibitors, and four involved integrase strand transfer inhibitors. The adjusted odds of receiving a contraindicated ARV were higher (3.25; 95% CI 1.40-7.57) among participants from east/central east Europe (vs. south) and lower (0.22; 95% CI 0.08-0.65) for 2015-2018 guidelines (vs. 2014). In total, 29 of the 32 (90.6%) patients receiving a contraindicated ARV and 441 of the 461 (95.7%) with potential ARV contraindications experienced a sustained virological response ≥12 weeks after stopping treatment (SVR12; p = 0.55). CONCLUSION: In this large heterogenous European cohort, more than one-third of people with HIV/HCV coinfection received DAAs with potential ARV contraindications, but few received a contraindicated ARV. Use of contraindicated ARVs declined over time, corresponding to the increased availability of ARV therapy regimens without interactions with DAA across Europe. Participants who received a contraindicated DAA and ARV combination still had a high rate of SVR12.

ABSTRACT
The HIV epidemic in Eastern Europe and Russia is large and not well-controlled. To describe the more recent molecular epidemiology of HIV-1, transmitted drug resistance, and the relationship between the epidemics in this region, we sequenced the protease and reverse transcriptase genes of HIV-1 from 812 people living with HIV from Ukraine (n = 191), Georgia (n = 201), and Russia (n = 420) before the initiation of antiretroviral therapy. In 190 Ukrainian patients, the integrase gene sequence was also determined. The most reported route of transmission was heterosexual contact, followed by intravenous drug use, and men having sex with men (MSM). Several pre-existing drug resistance mutations were found against non-nucleoside reverse transcriptase inhibitors (RTIs) (n = 103), protease inhibitors (n = 11), and nucleoside analogue RTIs (n = 12), mostly polymorphic mutations or revertants. In the integrase gene, four strains with accessory integrase strand transfer inhibitor mutations were identified. Sub-subtype A6 caused most of the infections (713/812; 87.8%) in all three countries, including in MSM. In contrast to earlier studies, no clear clusters related to the route of transmission were identified, indicating that, within the region, the exchange of viruses among the different risk groups may occur more often than earlier reported.

BACKGROUND: Life expectancy and quality of life of people living with HIV have been dramatically improved after introducing antiretroviral therapy, and the prevalence of non-communicable diseases has increased. Several studies have found that hyperglycemia with or without type 2 diabetes was associated with poor outcomes in people living with HIV. The study's objective was to determine the prevalence of hyperglycemia and assess its impact on mortality. MATERIALS AND METHODS: A retrospective cohort study was conducted among people living with HIV diagnosed in 2012-2018 and followed through 2020 at the Infectious Diseases, AIDS and Clinical Immunology Research Center in Tbilisi, Georgia. Primary outcomes of interest included the prevalence of hyperglycemia and mortality. Causes of death were classified according to the Coding of Death in HIV (CoDe) protocol. RESULTS: Our study included 2914 people living with HIV. Two hundred and forty-two (8.3%) patients had hyperglycemia, with an increasing prevalence by age. Three hundred one (9.7%) participants died over the median 3.71 (IQR: 2.14-5.37) years of follow-up. Among these, 139 (46.2%) were due to AIDS- related causes, 123 (40.9%)-were due to non-AIDS causes, and in 39 (12.9%) cases, the cause of death could not be determined. Overall, the cohort contributed to 11,148 person-years of follow-up (PYFU), translating into a mortality rate of 2.70 deaths per 100 PYFU. The mortality rate was significantly higher among individuals with hyperglycemia-11.17 deaths per 100 PYFU vs 2.07 deaths per 100 PYFU among normoglycemic patients(p<0.0001). CONCLUSIONS: Hyperglycemia was associated with increased odds of mortality. Screening and management of hyperglycemia should be integrated into routine HIV clinical services as part of a comprehensive care package.

OBJECTIVES: Although direct-acting antivirals (DAAs) can clear HCV in nearly all HIV/HCV-coinfected individuals, high rates of reinfection may hamper efforts to eliminate HCV in this population. We investigated reinfection after sustained virological response (SVR) in HIV/HCV-coinfected individuals in Europe. METHODS: Factors associated with odds of reinfection by 2 years after SVR in EuroSIDA participants with one or more HCV-RNA test and 2 years follow-up were assessed using logistic regression. RESULTS: Overall, 1022 individuals were included. The median age was 50 (interquartile range: 43-54 years), and most were male (78%), injection drug users (52%), and received interferon (IFN)-free DAAs (62%). By 24 months, 75 [7.3%, 95% confidence interval (CI): 5.7-8.9%] individuals were reinfected. Among individuals treated prior to 2014, 16.1% were reinfected compared with 4.2% and 8.3%, respectively, among those treated during or after 2014 with IFN-free and IFN-based therapy. After adjustment, individuals who had started treatment during or after 2014 with IFN-free or IFN-based therapy had significantly lower odds of reinfection (adjusted odds ratio = 0.21, 95% CI: 0.11-0.38; 0.43, 95% CI: 0.22-0.83) compared with those who had received therapy before 2014. There were no significant differences in odds of reinfection according to age, gender, European region, HIV transmission risk group or liver fibrosis. CONCLUSIONS: Among HIV/HCV-coinfected individuals in Europe, 7.3% were reinfected with HCV within 24 months of achieving SVR, with evidence suggesting that this is decreasing over time and with use of newer HCV regimens. Harm reduction to reduce reinfection and surveillance to detect early reinfection with an offer of treatment are essential to eliminate HCV.

OBJECTIVES: In some eastern European countries, serious challenges exist to meet the HIV-, tuberculosis (TB)- and hepatitis-related target of the United Nations Sustainable Development Goals. Some of the highest incidence rates for HIV and the highest proportion of multi-drug-resistant (MDR) tuberculosis worldwide are found in the region. The purpose of this article is to review the challenges and important next steps to improve healthcare for people living with TB, HIV and hepatitis C (HCV) in eastern Europe. METHODS: References for this narrative review were identified through systematic searches of PubMed using pre-idientified key word for articles published in English from January 2000 to August 2020. After screening of titles and abstracts 37 articles were identified as relevant for this review. Thirty-eight further articles and sources were identified through searches in the authors' personal files and in Google Scholar. RESULTS: Up to 50% of HIV/MDR-TB-coinfected individuals in the region die within 2 years of treatment initiation. Antiretroviral therapy (ART) coverage for people living with HIV (PLHIV) and the proportion virological suppressed are far below the UNAIDS 90% targets. In theory, access to various diagnostic tests and treatment of drug-resistant TB exists, but real-life data point towards inadequate testing and treatment. New treatments could provide elimination of viral HCV in high-risk populations but few countries have national programmes. CONCLUSION: Some eastern European countries face serious challenges to achieve the sustainable development goal-related target of 3.3 by 2030, among others, to end the epidemics of AIDS and tuberculosis. Better integration of healthcare systems, standardization of health care, unrestricted substitution therapy for all people who inject drugs, widespread access to drug susceptibility testing, affordable medicines and a sufficiently sized, well-trained health workforce could address some of those challenges.

BACKGROUND: Weight gain effects of individual antiretroviral drugs are not fully understood. We investigated associations between a prespecified clinically significant increase (>7%) in body-mass index (BMI) and contemporary antiretroviral use. METHODS: The International Cohort Consortium of Infectious Diseases (RESPOND) is a prospective, multicohort collaboration, including data from 17 well established cohorts and over 29 000 people living with HIV. People with HIV under prospective follow-up from Jan 1, 2012, and older than 18 years were eligible for inclusion. Each cohort contributed a predefined minimum number of participants related to the size of the specific cohort (with a minimum of 1000 participants). Participants were required to have CD4 cell counts and HIV viral load measurement in the 12 months before or within 3 months after baseline. For all antiretroviral drugs received at or after RESPOND entry, changes from pre-antiretroviral BMI levels (baseline) were considered at each BMI measurement during antiretroviral treatment. We used logistic regression to identify individual antiretrovirals that were associated with first occurrence of a more than 7% increase in BMI from pre-antiretroviral BMI. We adjusted analyses for time on antiretrovirals, pre-antiretroviral BMI, demographics, geographical region, CD4 cell count, viral load, smoking status, and AIDS at baseline. RESULTS: 14 703 people were included in this study, of whom 7863 (53·5%) had a more than 7% increase in BMI. Compared with lamivudine, use of dolutegravir (odds ratio [OR] 1·27, 95% CI 1·17-1·38), raltegravir (1·37, 1·20-1·56), and tenofovir alafenamide (1·38, 1·22-1·35) was significantly associated with a more than 7% BMI increase, as was low pre-antiretroviral BMI (2·10, 1·91-2·31 for underweight vs healthy weight) and Black ethnicity (1·61, 1·47-1·76 vs White ethnicity). Higher CD4 count was associated with a reduced risk of BMI increase (0·97, 0·96-0·98 per 100 cells per µL increase). Relative to lamivudine, dolutegravir without tenofovir alafenamide (OR 1·21, 95% CI 1·19-1·32) and tenofovir alafenamide without dolutegravir (1·33, 1·15-1·53) remained independently associated with a more than 7% increase in BMI; the associations were higher when dolutegravir and tenofovir alafenamide were used concomitantly (1·79, 1·52-2·11, and 1·70, 1·44-2·01, respectively). INTERPRETATION: Clinicians and people with HIV should be aware of associations between weight gain and use of dolutegravir, tenofovir alafenamide, and raltegravir, particularly given the potential consequences of weight gain, such as insulin resistance, dyslipidaemia, and hypertension.

We assessed trends in causes and outcomes of hospitalization among people living with HIV (PLWH) admitted to the Infectious Diseases, AIDS and Clinical Immunology Research Center (IDACIRC) in Tbilisi, Georgia. Retrospective analysis included adult PLWH admitted to IDACIRC for at least 24 h. Internationally validated categorization was used to split AIDS admissions into mild, moderate, and severe AIDS. A total of 2085 hospitalizations among 1123 PLWH were registered over 2012-2017 with 65.1% (731/1123) of patients presenting with CD4 count <200. Of 2085 hospitalizations, 931 (44.7%) were due to AIDS-defining illnesses. In 2012, AIDS conditions accounted for 50.3% of admissions compared to 41.6% in 2017 (p = 0.16). Overall, 167 hospitalizations (8.0%) resulted in lethal outcome. AIDS admissions had higher mortality than non-AIDS admissions (11.5% vs 5.2%, p < 0.0001). Among 167 deceased patients, 137 (82.0%) had CD4 count <200 at admission. In multivariate analysis, factors significantly associated with mortality included severe AIDS versus non-AIDS admission (OR 2.81, 95% CI: 1.10-7.15), CD4 cell counts <50 (OR 4.34, 95% CI: 2.52-7.47), and 50-100 (OR 2.37, 95% CI: 1.27-4.42) versus >200. Active AIDS disease remains a significant cause of hospitalization and fatal outcome in Georgia. Earlier diagnosis of HIV is critical for decreasing AIDS hospitalizations and mortality.

Among men who have sex with men (MSM) in low- or middle-income countries, smoking and related factors have been understudied. We examined correlates of smoking status, level, and importance and confidence regarding quitting among 608 MSM in the country of Georgia recruited in June-September, 2016 (493 without HIV via peer referral in 3 Georgian cities; 115 with HIV via the National AIDS Center). Median age was 26 years, 78.6% reported current (past 30-day) alcohol use, and 22.4% reported past-year illicit drug use. Overall, 73.8% reported current smoking; of these, 87.1% smoked daily, mean cigarettes per day (cpd) was 19.8, 64.6% smoked ≤30 min of waking, and mean quitting importance and confidence were 6.8 and 6.4 (0 = not at all to 10 = extremely), respectively. Multivariable analyses indicated that current smoking correlated with past-month alcohol and past-year illicit drug use (p's < .001). Among smokers, cpd correlated with being older and smoking within 30 min of waking; greater quitting importance (≥7) correlated with higher education and no illicit substance use; and greater quitting confidence (≥7) was associated with fewer cpd, smoking ≤30 min of waking, and regional versus capital city residence. Given these findings, addressing tobacco and other substance use among MSM in Georgia is critical.

BACKGROUND: Limited data exist that compare clinical outcomes of 2-drug regimens (2DRs) and 3-drug regimens (3DRs) in people living with human immunodeficiency virus. METHODS: Antiretroviral treatment-experienced individuals in the International Cohort Consortium of Infectious Diseases (RESPOND) who switched to a new 2DR or 3DR from 1 January 2012-1 October 2018 were included. The incidence of clinical events (AIDS, non-AIDS cancer, cardiovascular disease, end-stage liver and renal disease, death) was compared between regimens using Poisson regression. RESULTS: Of 9791 individuals included, 1088 (11.1%) started 2DRs and 8703 (88.9%) started 3DRs. The most common 2DRs were dolutegravir plus lamivudine (22.8%) and raltegravir plus boosted darunavir (19.8%); the most common 3DR was dolutegravir plus 2 nucleoside reverse transcriptase inhibitors (46.9%). Individuals on 2DRs were older (median, 52.6 years [interquartile range, 46.7-59.0] vs 47.7 [39.7-54.3]), and a higher proportion had ≥1 comorbidity (81.6% vs 73.9%). There were 619 events during 27 159 person-years of follow-up (PYFU): 540 (incidence rate [IR] 22.5/1000 PYFU; 95% confidence interval [CI]: 20.7-24.5) on 3DRs and 79 (30.9/1000 PYFU; 95% CI: 24.8-38.5) on 2DRs. The most common events were death (7.5/1000 PYFU; 95% CI: 6.5-8.6) and non-AIDS cancer (5.8/1000 PYFU; 95% CI: 4.9-6.8). After adjustment for baseline demographic and clinical characteristics, there was a similar incidence of events on both regimen types (2DRs vs 3DRs IR ratio, 0.92; 95% CI: .72-1.19; Pâ =â .53). CONCLUSIONS: This is the first large, international cohort to assess clinical outcomes on 2DRs. After accounting for baseline characteristics, there was a similar incidence of events on 2DRs and 3DRs. 2DRs appear to be a viable treatment option with regard to clinical outcomes. Further research on resistance barriers and long-term durability of 2DRs is needed.

BACKGROUND: Hepatitis C virus (HCV) infection has been associated with increased risk of chronic kidney disease (CKD). We investigated the impact of HCV cure on CKD in HIV-positive persons in the EuroSIDA study. METHODS: HIV-positive persons with known HCV status and at least three serum creatinine measurements after 1/1/2004 were compared based on time-updated HCV-RNA and HCV treatment: anti-HCV-negative, spontaneously cleared HCV, chronic untreated HCV, successfully treated HCV, and HCV-RNA positive after HCV treatment. Poisson regression compared incidence rates of CKD [confirmed (>3 months apart) eGFR <60âml/min per 1.73 m] between HCV strata. RESULTS: Fourteen thousand, seven hundred and fifty-four persons were included; at baseline 9273 (62.9%) were HCV-Ab negative, 696 (4.7%) spontaneous clearers, 3021 (20.5%) chronically infected, 922 (6.2%) successfully treated and 842 (5.7%) HCV-RNA positive after treatment. During 115â335 person-years of follow-up (PYFU), 1128 (7.6%) developed CKD; crude incidence 9.8/1000 PYFU (95% CI 9.2-10.4). After adjustment, persons anti-HCV negative [adjusted incidence rate ratio (aIRR) 0.59; 95% CI 0.46-0.75] and spontaneous clearers (aIRR 0.67; 95% CI 0.47-0.97) had significantly lower rates of CKD compared with those cured whereas persons chronically infected (aIRR 0.85; 95% CI 0.65-1.12) and HCV-RNA positive after treatment (aIRR 0.71; 95% CI 0.49-1.04) had similar rates. Analysis in those without F3/F4 liver fibrosis using a more rigorous definition of CKD showed similar results. CONCLUSION: This large study found no evidence that successful HCV treatment reduced CKD incidence. Confounding by indication, where those with highest risk of CKD were prioritized for HCV treatment in the DAA era, may contribute to these findings.

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.

BACKGROUND: In April 2015, in collaboration with the US Centers for Disease Control and Prevention and Gilead Sciences, the country of Georgia embarked on the world's first hepatitis C elimination program. We aimed to assess progress toward elimination targets 3 years after the start of the elimination program. METHODS: We constructed a hepatitis C virus (HCV) care cascade for adults in Georgia, based on the estimated 150 000 persons aged ≥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 were extracted from the national HCV screening database. For the treatment component, we utilized data from the Georgia National HCV treatment program database. Available treatment options included sofosbuvir and ledipasvir/sofosbuvir-based regimens. RESULTS: Since April 2015, a cumulative 974 817 adults were screened for HCV antibodies; 86 624 persons tested positive, of whom 61 925 underwent HCV confirmatory testing. Among the estimated 150 000 adults living with chronic hepatitis C in Georgia, 52 856 (35.1%) were diagnosed, 45 334 (30.2%) initiated treatment with direct-acting antivirals, and 29 090 (19.4%) achieved a sustained virologic response (SVR). Overall, 37 256 persons were eligible for SVR assessment; of these, only 29 620 (79.5%) returned for evaluation. The SVR rate was 98.2% (29 090/29 620) in the per-protocol analysis and 78.1% (29 090/37 256) in the intent-to-treat analysis. CONCLUSIONS: Georgia has made substantial progress in the path toward eliminating hepatitis C. Scaling up of testing and diagnosis, along with effective linkage to treatment services, is needed to achieve the goal of elimination.

OBJECTIVES: Survey was conducted to assess state of viral hepatitis care in Central and Eastern Europe (CEE). METHODS: Representatives of 16 CEE countries completed on-line survey in April-May 2017 that collected information on basic epidemiology and availability of key services for HCV and HBV infections. Sources of information provided ranged from national surveillance data to expert opinion. RESULTS: The burden of viral hepatitis varied between countries, ranging from 6,500 to 2 million for HCV and from 10,000 to 3 million for HBV. Access to routine HCV RNA testing and genotyping was reported by 11 and 9 countries, respectively. HCV resistance testing was available in 7 countries. Direct acting antivirals (DAAs) were available in 13 countries, most frequently Sofosbuvir and Ledipasvir/Sofosbuvir (12 countries apiece) and Ombitasvir/Paritaprevir/Dasabuvir (9 countries). HBV DNA testing and HBV genotyping were routinely available in 10 and 7 countries, respectively. Eleven countries reported available treatment with Tenofovir. CONCLUSIONS: There are gaps in viral hepatitis care in CEE. Despite the availability of registered modern drugs for HCV and HBV, the access to treatment is limited. Ensuring quality health care is essential to reduce the epidemic and achieve the WHO's goal of eliminating viral hepatitis as a major public health challenge.
