Prevalence of hepatitis C virus infection in patients with chronic mental disorders: The relevance of dual disorders

Profile of patients with a positive HCV viral load in a large French psychiatric hospital (2019–2021): A case–control study

“…International comparisons remain delicate, in view of all the differences in the composition of the general population and the impact on HCV prevalence, as well as differences in the psychiatric and hepatologic care systems, or methodological differences in the published studies. For example, in a recent Spanish study, a 3.8% seroprevalence of HCV and a 1.7% global rate of positive VLs were found in a population of patients admitted to psychiatry, which is thus different from the population included in our study 6 . Similarly, in a multicentre prospective study in Australia, the seroprevalence of HCV in psychiatric inpatients was 10.8%, 7 but the overall prevalence rate of HCV in PWMDs is known to be substantially higher in Australia or in the US than in Europe 3 .…”

Microelimination of Hepatitis C in Patients with Substance Use and Dual Disorders – a Portuguese Study

“…Compared to the general population, the prevalence of HCV infection is higher in individuals with psychiatric disorders (9). In addition, serious mental illness favors substance abuse, which increases the risk of blood-borne viral infections, such as HCV A c c e p t e d M a n u s c r i p t (9). The co-occurrence of substance-related disorders / addictive disorders with other mental disorders has been defined as dual disorders (9).…”

“…In Japan, this value is 9.1 times higher (12), and in Taiwan the prevalence of HCV antibodies in institutionalized psychiatric patients is 11.8% (13). More recent data from Spain identified an overall prevalence of HCV 3,8% reaching 14,3% among dual disorders patients (9).…”
