Study to Assess Neuroinflammation and Neurocognitive Function in Patients With Acute Hepatitis C and Chronic HIV Co-Infection - A Positron Emission Tomography (PET) Study

2014-08-27 03:20:02 | BioPortfolio

Summary

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.

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

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.

Medical and Biotech [MESH] Definitions

Acute INFLAMMATION of the LIVER in humans; caused by HEPATITIS E VIRUS, a non-enveloped single-stranded RNA virus. Similar to HEPATITIS A, its incubation period is 15-60 days and is enterically transmitted, usually by fecal-oral transmission.

A defective virus, containing particles of RNA nucleoprotein in virion-like form, present in patients with acute hepatitis B and chronic hepatitis. It requires the presence of a hepadnavirus for full replication. This is the lone species in the genus Deltavirus.

A form of rapid-onset LIVER FAILURE, also known as fulminant hepatic failure, caused by severe liver injury or massive loss of HEPATOCYTES. It is characterized by sudden development of liver dysfunction and JAUNDICE. Acute liver failure may progress to exhibit cerebral dysfunction even HEPATIC COMA depending on the etiology that includes hepatic ISCHEMIA, drug toxicity, malignant infiltration, and viral hepatitis such as post-transfusion HEPATITIS B and HEPATITIS C.

INFLAMMATION of the LIVER in humans due to infection by VIRUSES. There are several significant types of human viral hepatitis with infection caused by enteric-transmission (HEPATITIS A; HEPATITIS E) or blood transfusion (HEPATITIS B; HEPATITIS C; and HEPATITIS D).

A family of hepatotropic DNA viruses which contains double-stranded DNA genomes and causes hepatitis in humans and animals. There are two genera: AVIHEPADNAVIRUS and ORTHOHEPADNAVIRUS. Hepadnaviruses include HEPATITIS B VIRUS, duck hepatitis B virus (HEPATITIS B VIRUS, DUCK), heron hepatitis B virus, ground squirrel hepatitis virus, and woodchuck hepatitis B virus (HEPATITIS B VIRUS, WOODCHUCK).
