Antiretroviral Treatment Outcomes in HIV-HBV Co-infected Patients in Southern Africa

November 5, 2021 updated by: Michael Vinikoor, University of Alabama at Birmingham

Antiretroviral Treatment Outcomes in HIV-HBV Co-infected Patients in Southern Africa: a Collaborative Multi-country Prospective Cohort Analysis for International Epidemiologic Databases to Evaluate AIDS- Southern Africa (HIV/HBV-coinfection in IeDEA-SA)

This is a prospective HIV cohort that aims to establish causes of liver disease among HIV-infected individuals in Zambia, including viral hepatitis and alcohol.

Study Overview

Detailed Description

The study will take place during routinely scheduled ART visits as per Ministry of Health guidelines. Routinely collected programmatic data will be used to assess general HIV outcomes (CD4 response, loss to follow-up, death) as well as collecting study specific data (hepatitis testing, questionnaire regarding risk factors for hepatitis/liver disease, and non-invasive liver scan) to address other aims. The study will be implemented at two sites in Southern Africa (Zambia and Mozambique) with a total enrollment across all sites of 1,900 participants. The Zambia site will only enroll 900.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Immunological response
Time Frame: 12 months post enrollment
A linear mixed effect model will be used to evaluate immunological response to ART in patients with and without viral hepatitis
12 months post enrollment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
HIV virological response
Time Frame: 12 months post enrollment
Virological response will be evaluated using Cox regression analyses.
12 months post enrollment
Mortality
Time Frame: 12 months
Deaths will be ascertained
12 months
Hepatotoxicity events
Time Frame: 6 and 12 months
These events will be defined as an increase in the level of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 5 time the upper limit within the first year of ART.
6 and 12 months
Prevalence liver fibrosis
Time Frame: Baseline and one year after start of ART
The prevalence of liver fibrosis will be measured to compare HIV/hepatitis coinfected versus HIV monoinfected patients using transient elastography.
Baseline and one year after start of ART
HBV drug resistance
Time Frame: 1 and 2 years post enrollment
The presence of HBV drug resistance in co-infected patients who fail treatment after 1 year will be measured
1 and 2 years post enrollment
Incidence of HBV infection
Time Frame: 12 and 24 months post enrollment
The incidence of HBV infection during ART will be measured.
12 and 24 months post enrollment
Prevalence of HIV/HCV coinfection
Time Frame: Baseline
Describe prevalence of coinfection at ART initiation
Baseline
Alcohol use patterns
Time Frame: Baseline, 12, and 24 months
Describe the proportion with unhealthy levels of drinking before and after ART
Baseline, 12, and 24 months
