Association between Body Mass Index and Hepatitis B antibody seropositivity in children
Yoowon Kwon, Su Jin Jeong
Clin Exp Pediatr. 2019;62(11):416-421.   Published online August 12, 2019
Background: The seropositivity rate of hepatitis B surface antigen (anti-HBs) antibodies is known to be ≥95% after hepatitis B virus vaccination during infancy. However, a low level or absence of anti-HBs in healthy children is discovered in many cases. Recent studies in adults reported that a reduced anti-HBs production rate is related to obesity.
Purpose: To investigate whether body mass index...

Jang Hee Kang, Jae Won Moon, Seung Hyun Kong, Kwang Su Hwang, Ji Sun Mok, Hyeon Jung Lee
Clin Exp Pediatr. 2008;51(11):1165-1171.   Published online November 15, 2008
Purpose : This study aimed to identify the true extent of non-responsiveness in full-term infants born from HBsAg-negative or HBsAg-positive mothers and vaccinated against hepatitis B virus (HBV) at 0, 1, and 6 months of age and to evaluate the effect of revaccination among non-responders. Methods : The study included 716 full-term infants born in 2004-2007. Of 716, 662 infants...

Ui Chong Chong, Mi Ran Kim, Chong Young Park
Clin Exp Pediatr. 1999;42(6):778-782.   Published online June 15, 1999
Purpose : Hepatitis B virus infection is prevalent in Korea. Active immunization of Hepatitis B has been proceeded extensively for the last decade. This study was performed to estimate the negative rate of anti-HBs after immunization and to evaluate the effect of revaccination among Korean children between 1995 and 1997, as well as to determine a proper revaccination schedule. Methods :...
The Change of Anti-HBs Titer after Injection of HBIG and HBV in Newborn Delivered from HBsAg Carrier Mothers
Qoae Suk Roh, Jin Young Jung
Clin Exp Pediatr. 1997;40(8):1141-1148.   Published online August 15, 1997
Purpose : We studied prevention effects of vertical transmission of Hepatitis B with follow-up, through the change of Anti-HBs titers during 9 months after injection of Hepatitis B immunoglobulin(HBIG) and Hepatitis B vaccine(HBV) at birth in newborn delivered from Hepatitis antigen carrier mothers. Methods : This study was performed on newborn delivered from HBsAg carrier mothers at Hae Sung Hospital from Feb. 1995 to May...
