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.
