RESUMO

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.

RESUMO

Setting: Identification and screening of contacts of patients with active tuberculosis (TB) is infrequent in low- and middle-income countries. Objective: To estimate the incidence, prevalence and risk factors of latent tuberculous infection (LTBI) and active TB among contacts of newly reported smear-positive TB patients. Design: A population-based contact investigation of sputum smear-positive pulmonary TB (PTB) cases diagnosed between April and December 2012 in Georgia was conducted. LTBI was assessed using the tuberculin skin test (TST). Contacts with active TB were identified from the National TB Program surveillance database. Results: Among 896 index patients with active TB, 3133 contacts were identified and 1157 (37%) underwent a TST, 34% of whom were positive. Most contacts were household contacts (86%) and female (58%). Among contacts, the 1-year period prevalence of active TB was 3.3% (95%CI 2.70-3.98); the incidence rate was 1101 per 100 000 person-years (95%CI 822-1443). In multivariable analysis, household contacts were more likely to have LTBI (adjusted OR [aOR] 2.28, 95%CI 1.49-3.49) than close contacts. Conclusions: A high prevalence of both LTBI and active TB was identified among contacts of PTB cases. Efforts aimed at active case finding among TB contacts should improve early case detection and enhance TB control efforts.


Contexte : Identifier et dépister les contacts des patients atteints de tuberculose (TB) active n'est pas souvent réalisé dans les pays à revenu faible et moyen.Objectif : Estimer l'incidence, la prévalence et les facteurs de risque d'infection tuberculeuse latente (LTBI) et de TB active parmi les contacts de patients TB nouveaux à frottis positif.Schéma : Une investigation en population a été réalisée à la recherche des contacts de cas de TB pulmonaire à frottis positif diagnostiqués entre avril et décembre 2012 en Géorgie ; la LTBI a été évaluée grâce à un test cutané à la tuberculine (TST). Les contacts atteints de TB active ont été identifiés à partir de la base de données de surveillance du Programme National TB.Résultats : Parmi 896 patients index atteints de TB active, 3133 contacts ont été identifiés et 1157 (37%) ont eu un TST, dont 34% ont été positifs. La majorité des contacts ont été des contacts domiciliaires (86%) et des femmes (58%). Parmi les contacts, la prévalence sur un an de la TB active a été de 3,3% (IC95% 2,70­3,98) tandis que le taux d'incidence a été de 1101 par 100 000 années-personne (IC95% 822­1443). En analyse multivariée, les contacts domiciliaires ont été plus susceptibles d'avoir une LTBI (OR ajusté [ORa] 2,28 ; IC95% 1,49­3,49) comparés aux contacts étroits.Conclusion : Une prévalence élevée à la fois de LTBI et de TB active a été identifiée parmi les contacts des cas de TB pulmonaire. Les efforts visant à une recherche active de cas parmi les contacts de TB devraient améliorer une détection précoce des cas et renforcer les efforts de lutte contre la TB.


Marco de referencia: La localización y la investigación de contactos de pacientes con tuberculosis (TB) activa rara vez se siguen en los países con ingresos bajos y medianos.Objetivo: Estimar la incidencia, la prevalencia y los factores de riesgo de contraer la infección tuberculosa latente (LTBI) y la TB activa en los contactos de los casos nuevos de TB con baciloscopia positiva notificados.Método: Se llevó a cabo una investigación de base poblacional de los contactos de casos de TB pulmonar con baciloscopia positiva diagnosticados de abril a diciembre del 2012 en Georgia; se investigó la LTBI mediante la prueba cutánea de la tuberculina (TST). Los contactos con TB activa se localizaron en la base de datos de vigilancia del Programa Nacional contra la Tuberculosis.Resultados: Se reconocieron 3133 contactos de los 896 casos iniciales con TB activa y se practicó la TST en 1157 (37%), de los cuales el 34% obtuvo un resultado positivo. La mayoría de los contactos fueron contactos domiciliarios (86%) y de sexo femenino (58%). En los contactos, la prevalencia a un año de TB activa fue 3,3% (IC95% 2,70­3,98) y la tasa de incidencia fue 1101 por 100 000 años-persona (IC95% 822­1443). El análisis multivariante reveló que la probabilidad de padecer la ITL era mayor en los contactos domiciliarios (cociente de posibilidades ajustado 2,28; IC95% 1,49­3,49) que los contactos directos (no domiciliarios).Conclusiones: Se encontró una alta prevalencia de LTBI y de TB activa en los contactos de los casos de TB pulmonar. Las iniciativas de búsqueda activa de casos en los contactos de los pacientes con TB deberían mejorar la detección temprana y reforzar los esfuerzos de control de la TB.
