Trial Outcomes & Findings for Liver Fibrosis in Zambian HIV-HBV Co-infected Patients (NCT NCT02344680)

NCT ID: NCT02344680

Last Updated: 2026-07-02

Results Overview

Based on transient elastography, we calculated the number and proportion of participants with at least significant fibrosis at their first measure who regressed to minimal-no fibrosis during follow-up. This outcome excluded participants with no-minimal fibrosis at enrollment.

Participant Flow

Adults who were newly entering HIV care were screened for study eligibility and if they met all criteria and gave informed consent, they enrolled.

This was a single arm prospective cohort study. All participants received standard of care medication for treatment of HBV/HIV coinfection.

PRIMARY outcome

Timeframe: From baseline to 10 years of follow-up

Population: Due to losses to follow-up, transfers, deaths, and withdrawals from the study, the total number analyzed for this outcome was reduced.

Based on transient elastography, we calculated the number and proportion of participants with at least significant fibrosis at their first measure who regressed to minimal-no fibrosis during follow-up. This outcome excluded participants with no-minimal fibrosis at enrollment.

SECONDARY outcome

Timeframe: From baseline to 10 years of follow-up

Population: We attempted to document new cases of HCC during follow-up. HCC in Zambia is based on international criteira including triple phase CT scan +/- histology. During the study, every 6-12 months we performed an abdominal ultrasound to screen for liver masses.

All-cause mortality
13.5%
47/349 • From enrollment to up to 10 years of follow-up
Participants received standard of care treatments. During follow-up, we ascertained SAEs, including all-cause mortality, which was based on verbal reported by participant family/friend or documented by the clinic. In Zambia is it very challenging to obtain death records (due to limitations in vital statistics infrastructure) and to determine specific causes of death (because most people die at home and few families allow autopsies). Other (Not Including Serious) Adverse Events were not monitored

Other adverse events

Adverse event data not reported
