Abstract：Objective To explore the related factors of serum β2-microglobulin concentration after long-term administration of interferon in children with chronic hepatitis B (CHB). Methods Serum samples of 108 children with CHB who were treated at the Fifth Medical Center of People’s Liberation Army General Hospital from December 2017 to September 2019 were collected after long-term interferon α1b application. Multiple linear regression analysis method was used, with serum β2-microglobulin concentration as the dependent variable, taking gender, age, body mass index (BMI), course of treatment, administration time (the interval between sampling time and the last medication before sampling), administration dose, virus genotyping and other information as independent variables, the related influencing factors of serum β2-microglobulin concentration were analyzed. Results There was no correlation between β2-microglobulin and age, course of treatment, time of administration and BMI (P ＞ 0.05). There were no statistically significant differences in different genders, viral hepatitis type B genotypes, and doses of β2-microglobulin (P ＞ 0.05). Dosage, age, time of administration, and course of treatment are related factors that affect the concentration of serum β2-microglobulin (P ＜ 0.05), among them, the serum β2-microglobulin concentration increases with the increase of the dose, and decreases with the increase of age, administration time and treatment course. Conclusion The concentration of serum β2-microglobulin is not only related to the dose, but the time, duration of treatment and age also have certain effects on the concentration of serum β2-microglobulin.
