The authors studied on 77 children with acute hepaticis who admitted to the pediatric department of Chungnam National University Hospital during the period of 2 years from April 1982 to March 1984 to observe frequency of Hepatitis B antigen & antibody and to analysis any differences between Band Non-B marker groups by age, sex, living place, duration of hospitalization and various lab. paramenters.
The results are summarized as follows:
1. Positive rates of HBs Ag, HBs Ab. HBc Ab, and HBe Ag, tested seperatedly were encountered in 20.8, 15.6, 29.9 and 14.3% respectively.
2. In cases rested both HBs Ag,& HBs AB, positive rates of HBs Ag, or HBs Ab. and both were 16.9, 11.7 and 3.9%
3. In cases tested HBs Ag, HBs Ab. and HBc Ab. postive rates of HBs Ag, or HBcAb were 5.2& 6.5% those of HBs Ag. & Hbc Ab or HBs Ab, & HBc Ab. being each 11.7% those of HBsAg, HBs Ab & HBc Ab. being 3.9%
4. In cases tested HBs Ag. HBs Ab. HBc Ab and HBe Ag. negative rates of HBs Ag or HBc Ab were 2.6% and 6.5% and positive rates of HBs Ag & HBc Ab being 3.9% Those of HBs Ab & HBc Ab being 3.9% of Hbs Ab & Hbc Ab being 11.7% of HBs Ag, Hbc Ab & HBe Ag Being 7.8% of HBs Ag and HBeAg 2.6% and of all antigen & antibody being 3.9%.
5. Hepatitis B marker demonstrated higher in older than younger age groups.
6. Childhood Hepatitis were more frequently occurred in boys than in girls and in urban than in rural ares.
7. Duration of hospitalization is more prolonged in B-marker positive than in negative groups.
