Observational Study on Prevalence of Host and Viral Genotypes in Chronic Hepatitis B and Hepatitis C Patients in India

July 7, 2015 updated by: Gilead Sciences

Prevalence of Host and Viral Genotypes in Patients With Chronic Hepatitis B and Hepatitis C Infection in India

This study will define the substantial disease burden associated with viral hepatitis in India, and provide a foundation to understand the host and viral determinants of disease pathogenesis that may ultimately impact treatment decisions and outcome

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The overall goal of this study is to correlate the host and viral genetics of patients infected with viral hepatitis with their clinical presentation. This study will provide the first nation-wide estimate of key host genetic polymorphisms associated with immune response, such as in the IL28B gene locus which has been associated with treatment outcomes in hepatitis C. Characterization of HCV and HBV viral genotypes and sub-types across different geographic regions will allow for an exploration of associations between host and viral genotypes. Another objective of this study is to identify co-morbid illness and metabolic factors that are associated with chronic liver disease due to viral hepatitis. Finally, this survey will explore patient awareness of their disease, risk factors for disease progression, and their treatment options

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Description

Inclusion Criteria:

  • Willing and able to provide written informed consent
  • Male or female, age >= 18
