About this trial
This is an interventional other trial for Acute Hepatitis C focused on measuring Acute hepatitis C, HIV, Neurocognitive function, Neuroinflammation
Eligibility Criteria
Inclusion Criteria:
- HIV-1 antibody positive for at least 12 months
- Acute HCV (Blood HCV PCR positive with negative PCR within past 8 months)
- HCV genotype 1
- Ability to give informed consent
- Aged > 25 years
- Male
- Abbreviated Mental Test Score of at least 8/10
Exclusion Criteria:
- Evidence of established cirrhosis or encephalopathy
- Commencing or any change to HIV medications within 12 weeks
- Active opportunistic infection
- Taking anti-depressants or any psychoactive medications within past 4 weeks
- Use of benzodiazepines within past 4 weeks
- Recent significant head injury
- Established dementia
- Alcohol dependence or recreational drug misuse
- Untreated early syphilis
- Hepatitis B infection (HBsAg positive)
- Pregnancy
- Unable to give informed consent
- Any contraindication to MR scanning
Sites / Locations
- St Mary's Hospital

Arm Label
HIV/acute HCV coinfection

Arm Description
Subjects with HIV/acute HCV coinfection (aHCV cases) were required to have acute HCV, defined by a new positive plasma HCV RNA test within 12 months of a negative HCV RNA test.
HIV-infected individuals without hepatitis C co-infection
Outcomes
Primary Outcome Measures
Association of 11C-labelled PK11195 Uptake Using PET With Acute HCV and HIV Infection
Association of 11C-labelled PK11195 uptake using PET with acute HCV and HIV infection by PK11195 PET ligand binding. The ligand PK11195 is selective for the peripheral benzodiazepine binding site and exhibits minimal binding in normal brain. In brain lesions, however, there is a massive increase in binding.
Secondary Outcome Measures
Ratio of NAA/Cr (N-acetyl Aspartate/Creatine) Cerebral Metabolites
Association between patient characteristics and 11C-labelled PK11195 uptake using PET, CNS metabolite ratios.
By quantifying the surrogate markers of N-acetylaspartate (NAA), creatine (Cr) offers insight into the neuronal integrity, cell membrane synthesis and turnover, macrophage infiltration, inflammation status, and levels of microglial activation and gliosis within the sampled CNS tissue.

5. Study Description
Brief Summary
This study plans to evaluate what happens to the brain in patients with HIV and early hepatitis C. The investigators will be comparing 3 groups of individuals:
Group 1: Individuals with HIV infection and acute (early) hepatitis C infection
Group 2: Individuals with HIV infection
Group 3: Healthy volunteers
Detailed Description
Subtle changes to the brain, which doctors find difficult to detect through conversation or examination, may occur in patients with HIV and/or hepatitis C infection. It is not currently known whether the brain is affected in early (or acute) hepatitis C.
Individuals wishing to take part will complete a series of tests assessing different aspects of their brain including:
2 brain scans using different technology:
Magnetic resonance imaging (MRI) brain scan with spectroscopy
CT PET brain scan
A computer game test which measures brain function
2 short questionnaires
Results of these tests will be analyzed and compared between 3 groups.
