          Abstract

          Resumen La infección crónica por el virus de la hepatitis C (VHC) afecta a 58 millones de personas y es una importante causa de morbimortalidad alrededor del mundo. La reinfección por VHC es un problema creciente en personas con factores de riesgo como consumo pesado de alcohol, sexo anal, sexo grupal y compartir agujas y jeringas; este tipo de infección se define como un nuevo contagio de VHC con un genotipo viral diferente al de la primera infección en un paciente luego de lograr una respuesta viral sostenida (RVS). La reinfección se presenta, en parte, debido a la ausencia de estrategias de promoción y prevención. Teniendo en cuenta estos antecedentes, se han propuesto estrategias más pragmáticas para controlar la infección por VHC y evitar la reinfección, tales como la microeliminación. En el presente artículo se presenta un caso de un paciente que presenta alteración en los marcadores de la bioquímica hepática, por lo que se solicita una prueba diagnóstica de infección por VHC y luego genotipificación viral, y se evidenció una infección por VHC genotipo 1, subgenotipo 1A. Se inició el manejo con antivirales de acción directa y se documentó una adecuada RVS12. Tres meses después el paciente regresó a consulta y en los exámenes de control se evidenció una carga viral elevada de VHC, por lo que se solicitó genotipificación y se demostró una nueva infección por VHC genotipo 4.

          Abstract Chronic hepatitis C (HCV) infection affects 58 million people and is a significant cause of morbidity and mortality worldwide. HCV reinfection is a growing problem in people with risk factors such as heavy alcohol use, anal sex, group sex, and sharing needles and syringes. This type of infection is defined as a new HCV infection with a different viral genotype than the first infection in a patient after achieving a sustained viral response (SVR). Reinfection occurs, in part, due to the absence of promotion and prevention strategies. Taking this background into account, more pragmatic approaches have been proposed to control HCV infection and avoid reinfection, such as micro elimination. This article reports the case of a patient with alterations in biochemical liver markers, for which a diagnostic test for HCV infection and then viral genotyping was requested. Infection by HCV genotype 1, subgenotype 1A, was evidenced. Management with direct-acting antivirals was started, and an adequate SVR12 was documented. Three months later, the patient returned, and the control tests showed a high HCV viral load, for which genotyping was requested, showing a new HCV genotype 4 infection.

          Global epidemiology of hepatitis C virus infection: new estimates of age-specific antibody to HCV seroprevalence.

          In efforts to inform public health decision makers, the Global Burden of Diseases, Injuries, and Risk Factors 2010 (GBD2010) Study aims to estimate the burden of disease using available parameters. This study was conducted to collect and analyze available prevalence data to be used for estimating the hepatitis C virus (HCV) burden of disease. In this systematic review, antibody to HCV (anti-HCV) seroprevalence data from 232 articles were pooled to estimate age-specific seroprevalence curves in 1990 and 2005, and to produce age-standardized prevalence estimates for each of 21 GBD regions using a model-based meta-analysis. This review finds that globally the prevalence and number of people with anti-HCV has increased from 2.3% (95% uncertainty interval [UI]: 2.1%-2.5%) to 2.8% (95% UI: 2.6%-3.1%) and >122 million to >185 million between 1990 and 2005. Central and East Asia and North Africa/Middle East are estimated to have high prevalence (>3.5%); South and Southeast Asia, sub-Saharan Africa, Andean, Central, and Southern Latin America, Caribbean, Oceania, Australasia, and Central, Eastern, and Western Europe have moderate prevalence (1.5%-3.5%); whereas Asia Pacific, Tropical Latin America, and North America have low prevalence (<1.5%). The high prevalence of global HCV infection necessitates renewed efforts in primary prevention, including vaccine development, as well as new approaches to secondary and tertiary prevention to reduce the burden of chronic liver disease and to improve survival for those who already have evidence of liver disease.

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

              Background 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. Methods 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). Findings Between 1990 and 2013, global viral hepatitis deaths increased from 0·89 million (95% uncertainty interval [UI] 0·86–0·94) to 1·45 million (1·38–1·54); YLLs from 31·0 million (29·6–32·6) to 41·6 million (39·1–44·7); YLDs from 0·65 million (0·45–0·89) to 0·87 million (0·61–1·18); and DALYs from 31·7 million (30·2–33·3) to 42·5 million (39·9–45·6). 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. Interpretation 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.
