Hepatitis C Burden in Greece, Italy, Portugal, and Spain: 2000-2019

ABSTRACT

Background: Viral Hepatitis remains a health priority. We performed a comprehensive evaluation of epidemiological HCV estimates in Southern countries of Western Europe and assessed the impact of the 2008 economic crisis on HCV burden. Method(s) We analyzed data of the Global Burden of Diseases to describe the patterns of six measures of HCV burden [prevalence, incidence, mortality, years lived with disability (YLDs), years of life lost (YLLs), disability adjusted life years (DALYs)] in Greece, Italy, Portugal, Spain. We assessed age-standardized rates (per 100,000 population) between 2000-2019, disaggregated by sex and age, and compared the annualized age-standardized rate of change (ARC%) in 2000-2010 (pre-austerity) and 2010-2019 (post-austerity). Result(s) Prevalence, incidence and YLDs rates of acute HCV showed a general stable trend in Western Europe (WE), globally and in the four studied countries except Italy, where, despite a marked decline (ARC 1.4% in 2010-2019), the 2019 estimates [7.8 (95% UI 6.6-9.2)] were still 1.7-fold higher than in WE. Mortality, YLLs and DALYs associated with acute HCV decreased in the analyzed countries and peaked in Greece post-austerity. Globally and in Greece, mortality rate was higher in females than in males (1.3-times and 1.5-times in 2019, respectively). Mortality caused by chronic liver diseases including cirrhosis decreased globally, in WE and in all countries albeit at a lower rate in the post-austerity period (decrease in ARC for WE 2.5% in 2000-2010;1.6 in 2010-2019). Liver cancer prevalence due to HCV increased in WE (ARC 2.1%) and in the analyzed countries mainly in the pre-austerity period except for Italy. However, despite having the highest prevalence rate in both sexes, Italy showed major decreases in all six-disease metrics. HCV liver cancer mortality declined significantly only in Italy (ARC 2.6%) and globally (ARC 2.1%) especially in the pre-austerity period, while Portugal experienced a major increase postausterity. Overall, males and people over 70 years old are at greater risk of developing chronic liver diseases due to HCV infection. Conclusion(s) The economic crisis of 2008 negatively impacted hepatitis C related liver cancer mortality rates in Greece, Italy, Portugal and Spain. Despite the observed recovery in recent years, elimination of HCV infection by 2030 will be a major challenge in these countries and the COVID-19 pandemic and the current grim economic context are expected to compromise even further hepatitis C elimination.
