Changes in Cognition in HCV Patients After Virus Eradication With Direct Antiviral Agents
Changes in Cognition in HCV Patients After Virus Eradication With Direct Antiviral Agents
Study about the improvement of cognitive, psychopathological and functional abilities in
 Hepatitis C Virus (HCV) infected patients after eradication of the virus with direct
 antiviral agents.
The aim of this study is to investigate the effect that the eradication of the HCV has on
 cognition, quality of life and psychopathology. At the same time, investigators intend to
 study the association between cognitive changes and some clinical variables.

 The sample consists of 80 subjects (40 HCV patients and 40 HCV patients coinfected with the
 Human Immunodeficiency Virus, HIV). Exclusion criteria: Cirrhosis, presence of minimal
 hepatic encephalopathy or active drug consumption.

 A neuropsychological assessment is made before the treatment with direct antiviral agents to
 evaluate memory, executive functions, processing speed, anxiety, depression and quality of
 life. Additionally, the following clinical variables are collected: Viral charge,
 immunosuppression (measured with T Cells CD4 (CD4), CD4 nadir and T Cells CD8 (CD8)) and
 fibrosis level, HCV genotype and plasma biomarkers: Brain-Derived Neurotrophic Factor (BDNF),
 Interleukine 6 (IL6), Tumor Necrosis Factor (TNF-a),Glial fibrillary acidic protein (GFAP),
 Soluble CD14 (SCD14), Neuro-specific enolase (NSE).

 The second neuropsychological assessment and clinical data collection is carried out after
 treatment, concretely 6 months after HCV is undetectable in plasma.
Inclusion Criteria:

 -  Patients over 18 years old with indication to receive antiviral treatment

 -  Diagnosis of chronic infection by hepatitis C virus in the fibrous phase F3 or F4 that
 have not presented any clinical decompensation of their liver disease, with or without
 HIV co-infection

 Exclusion Criteria:

 -  Active alcohol consumption> 40g daily or history of chronic alcoholism

 -  Active consumption of other toxics (heroin, cocaine, cannabis)

 -  Patients with minimum hepatic encephalopathy

 -  Background of cerebral neurological disease, chronic renal insufficiency and / or
 psychiatric illnesses assessed according to the Diagnostic and Statistical Manual of
 Mental Disorders (DSM-5) criteria, which can affect cognitive functions.

 -  Active use of psychotropics or benzodiazepines
