  Purpose

This is an ancillary to the NIDDK-sponsored Hepatitis B Research Network (HBRN) Study Cohort Study NCT01263587. This study will examine the balance between immune regulatory and effector responses in hepatitis B-infected participants enrolled in the HBRN study (NCT01263587).


Condition

Primary Outcome Measures:
  • Immune regulatory and activation measures [ Time Frame: 240 weeks ] [ Designated as safety issue: No ]
    Immune regulatory and effector responses relative to HBV DNA, ALT and clinical outcome. HBV-specific lymphoproliferative, IFN-gamma and IL 10 responses, T cell activation and costimulatory markers (PD1, CTLA4, CD28, CD127), FoxP3+ Treg frequency, and NK frequency and expression of activating/inhibitory receptors and Dendritic cell frequency.


Biospecimen Retention:   Samples Without DNA

Blood


Estimated Enrollment: 300
Study Start Date: February 2011
Estimated Study Completion Date: May 2015
Estimated Primary Completion Date: May 2015 (Final data collection date for primary outcome measure)
Detailed Description:

Aim 1: The clinical and virological status of chronic Hepatitis B (HBV) infection is defined by distinct patterns of immune effector and regulatory responses: The investigators propose that one or more immune regulatory are induced during chronic hepatitis B that define the extent of immune tolerance vs. activation with associated disease activity and viremia. Towards this end, the immune effector and regulatory responses relative to serum HBV DNA, alanine aminotransferase (ALT), Hepatitis B e antigen (HBeAg), Hepatitis B surface antigen (HBsAg) and liver histology will be examined in a cross-sectional manner in patients with chronic HBV and control groups.

Aim 2: Clinical hepatitis flares during chronic hepatitis B reflect altered balance between immune regulatory and effector responses.
