About this study

Official title: 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.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Memory tests

    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.

    Measured: baseline, change at 6 months after treatment

  2. Attention tests

    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.

    Measured: baseline, change at 6 months after treatment

  3. Executive function tests

    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.

    Measured: baseline, change at 6 months after treatment

  4. Speed processing test

    Digit symbol test (WAIS III, Wechsler 1997) assesses visuomotor speed. The direct scores have been transformed into T-scores (mean=50; SD=10).

    Measured: baseline, change at 6 months after treatment

Secondary outcomes (5)
  1. Hospital Anxiety and Depression Scale (HADS)

    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.

    Measured: baseline, change at 6 months after treatment

  2. 36-Item Short Form Health Survey (SF-36 )

    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).

    Measured: baseline, change at 6 months after treatment

  3. Fibroscan

    Degree of fibrosis: Speed of propagation of elastic waves measured with fibroscan.

    Measured: Baseline, change at 6 months after treatment

  4. HCV RNA

    Viral load quantity measured by plasma HCV RNA is collected in HIV co-infected patients

    Measured: Baseline, change at 3 months after treatment, change at 6 months after treatment.

  5. Immunosuppression state

    The next cells were analyzed in blood, in HIV co-infected patients : CD4, %CD4, nadir CD4, CD8, % CD8, CD4/CD8 ratio.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of HCV Infection and HCV Coinfection, run by Corporacion Parc Tauli.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Memory tests (time frame: baseline, change at 6 months after treatment). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Feb 2019.
