Impact of Hepatitis B Virus Genotype on Treatment Response in Children With Chronic Hepatitis B

March 15, 2024 updated by: Ly Hoa Anh Minh
The study aimed to evaluate the relationship between hepatitis B virus genotype and treatment response in children with chronic hepatitis B with specific treatment indications. This is a prospective cohort study, with a follow-up period of at least 12 months, conducted at Children's Hospital 1 and City Children's Hospital, Ho Chi Minh City, Vietnam. The patient's blood was taken to be tested for hepatitis B virus genotyping using Sanger sequencing at the Center for Molecular Biomedicine Ho Chi Minh City. The research hypothesis is that genotype is related to treatment response.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Serological response for HBeAg
Time Frame: 12 months after treatment
Serological response for HBeAg applies only to patients with HBeAg-positive Chronic Hepatitis B and is defined as HBeAg loss and seroconversion to anti-HBe.
12 months after treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Virological response
Time Frame: 12 months after treatment
Virological response is defined as undetectable HBV DNA by a sensitive PCR assay.
12 months after treatment

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Biochemical response
Time Frame: 12 months after treatment
Biochemical response is defined as normalisation of ALT levels
12 months after treatment
