Changes in Cognition in HCV Patients After Virus Eradication With Direct Antiviral Agents. Relationship With Clinical and Sociodemographic Variables

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.

Descrição detalhada

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.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Memory tests
Prazo: baseline, change at 6 months after treatment
Rey Auditory Verbal Learning Test (RVLT, Spreen & Strauss 1998) assesses verbal learning, recall and recognition memory; Wechsler Adults Intelligence Scale III backward digits subtest (WAIS, Wechsler 1997) assesses working memory. All direct scores have been transformed into T-scores (mean=50; SD=10), which allows to obtain a single memory component.
baseline, change at 6 months after treatment
Attention tests
Prazo: baseline, change at 6 months after treatment
Continous Performance Test (CPT, Conners 2000) assesses sustained attention, inattentiveness and impulsivity; WAIS forward digits subtest (WAIS III, Wechsler 1997) assesses attention. All direct scores have been transformed into T-scores (mean=50; SD=10), which allows to obtain a single attention component.
baseline, change at 6 months after treatment
Executive function tests
Prazo: baseline, change at 6 months after treatment
Stroop Test (Stroop, 1935) assesses flexibility and inhibition of automatic responses; Trail Making Test (TMTA-B Reitan, 1993) assesses visual tracking and flexibility, phonetic and semantic fluency tests (Lezak, 1995) assess verbal fluency; Tower of London (Culbertson & Zillmer, 2005) assesses visual reasoning and planification. All direct scores have been transformed into T-scores (mean=50; SD=10), which allows to obtain a single executive function component.
baseline, change at 6 months after treatment
Speed processing test
Prazo: baseline, change at 6 months after treatment
Digit symbol test (WAIS III, Wechsler 1997) assesses visuomotor speed. The direct scores have been transformed into T-scores (mean=50; SD=10).
baseline, change at 6 months after treatment

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Hospital Anxiety and Depression Scale (HADS)
Prazo: baseline, change at 6 months after treatment

It is a self-registering scale of 14 items: 7 items evaluating anxiety and 7 items evaluating depression (Zigmond & Snaith, 1983).

Scoring range: 0-21 for each subscale. Scores >10 in each subscale imply a significant anxious/depressive symptomatology.

baseline, change at 6 months after treatment
36-Item Short Form Health Survey (SF-36 )
Prazo: baseline, change at 6 months after treatment
It is a self-registered scale for the assessment of quality of life ( Alonso y cols. , 1995). It consists on 8 dimensions: Physical functioning, limitations for physical issues, corporal pain, social functioning, mental health, limitations for emotional issues, vitality and general perception of the own health. For each dimension, the scoring range goes from 0 to 100, where higher values represent better outcome (better quality of life/less limitations/better functioning).
baseline, change at 6 months after treatment
Fibroscan
Prazo: Baseline, change at 6 months after treatment
Degree of fibrosis: Speed of propagation of elastic waves measured with fibroscan.
Baseline, change at 6 months after treatment
HCV RNA
Prazo: Baseline, change at 3 months after treatment, change at 6 months after treatment.
Viral load quantity measured by plasma HCV RNA is collected in HIV co-infected patients
Baseline, change at 3 months after treatment, change at 6 months after treatment.
Immunosuppression state
Prazo: Baseline
The next cells were analyzed in blood, in HIV co-infected patients : CD4, %CD4, nadir CD4, CD8, % CD8, CD4/CD8 ratio.
Baseline
