Absence of occult hepatitis B virus infection in sera of diabetic children and adolescents following hepatitis B vaccination.

Background: The prevalence of occult hepatitis B (HB) infection (OBI) in HB-vaccinated diabetic children has not yet been tested. Here, we aimed to determine the prevalence of OBI among HB-vaccinated children and adolescents with insulin-dependent diabetes mellitus (IDDM).

Results: Eighty-seven (51.

Antibody levels against hepatitis B virus after hepatitis B vaccination in Egyptian diabetic children and adolescents.

Background: The remarkable effectiveness of universal infantile hepatitis B (HB) vaccination is well documented in many countries. Nevertheless, the influence of insulin-dependent diabetes mellitus (IDDM) on the sero-protective level of antibody to hepatitis B surface antigen (anti-HBs) after HB vaccination has not been investigated in Egyptian children. The aim of this study was to investigate long-term anti-HBs sero-protective levels after infantile HB vaccination in Egyptian IDDM children.
