The global burden of viral hepatitis from 1990 to 2013: findings from the Global Burden of Disease Study 2013

Abstract

Background<BR>With recent improvements in vaccines and treatments against viral hepatitis, an improved understanding of the burden of viral hepatitis is needed to inform global intervention strategies. We used data from the Global Burden of Disease (GBD) Study to estimate morbidity and mortality for acute viral hepatitis, and for cirrhosis and liver cancer caused by viral hepatitis, by age, sex, and country from 1990 to 2013.<BR>Methods<BR>We estimated mortality using natural history models for acute hepatitis infections and GBD's cause-of-death ensemble model for cirrhosis and liver cancer. We used meta-regression to estimate total cirrhosis and total liver cancer prevalence, as well as the proportion of cirrhosis and liver cancer attributable to each cause. We then estimated cause-specific prevalence as the product of the total prevalence and the proportion attributable to a specific cause. Disability-adjusted life-years (DALYs) were calculated as the sum of years of life lost (YLLs) and years lived with disability (YLDs).<BR>Findings<BR>Between 1990 and 2013, global viral hepatitis deaths increased from 0ı89 million (95% uncertainty interval [UI] 0ı86-0ı94) to 1ı45 million (1ı38-1ı54); YLLs from 31ı0 million (29ı6-32ı6) to 41ı6 million (39ı1-44ı7); YLDs from 0ı65 million (0ı45-0ı89) to 0ı87 million (0ı61-1ı18); and DALYs from 31ı7 million (30ı2-33ı3) to 42ı5 million (39ı9-45ı6). In 2013, viral hepatitis was the seventh (95% UI seventh to eighth) leading cause of death worldwide, compared with tenth (tenth to 12th) in 1990.<BR>Interpretation<BR>Viral hepatitis is a leading cause of death and disability worldwide. Unlike most communicable diseases, the absolute burden and relative rank of viral hepatitis increased between 1990 and 2013. The enormous health loss attributable to viral hepatitis, and the availability of effective vaccines and treatments, suggests an important opportunity to improve public health.<BR>Quelle: http://www.sciencedirect.com
