Hasan M. Isa, Masooma S. Mohamed, Afaf M. Mohamed, Adel Abdulla, Fuad Abdulla
Clin Exp Pediatr. 2017;60(4):106-111.   Published online April 25, 2017
Purpose

This study aimed to determine the prevalence of glucose-6-phosphate dehydrogenase (G6PD) deficiency among infants with neonatal indirect hyperbilirubinemia (NIH); compare G6PD-deficient and G6PD-normal patients regarding hyperbilirubinemia and need for exchange transfusions (ET); and assess risk factors for ET and kernicterus.

Methods

This is a case-control retrospective study. Medical records of NIH patients admitted to the Pediatric Department, Salmaniya Medical Complex, Bahrain, between...

Glutathione S-transferase polymorphism of neonatal hyperbilirubinemia in Korean neonates
Chang Seok Kang, Seung Su Hong, Ji Sook Kim, Eun Ryoung Kim
Clin Exp Pediatr. 2008;51(3):262-266.   Published online March 15, 2008
Purpose : Glutathione S-transferase (GST) is a polymorphic supergene family of detoxification enzymes that are involved in the metabolism of numerous diseases. Several allelic variants of GSTs show impaired enzyme activity and are suspected to increase the susceptibility to diseases. Bilirubin is bound efficiently by GST members. The most commonly expressed gene in the liver is GSTM1, and GSTT1 is...
The relation between angiotensin converting enzyme (ACE) gene polymorphism and neonatal hyperbilirubinemia in Korea
Mi Yeoun Kim, Jae Myoung Lee, Ji Sook Kim, Eun Ryoung Kim, Hee Jae Lee, Seo Hyun Yoon, Joo Ho Chung
Clin Exp Pediatr. 2007;50(1):28-32.   Published online January 15, 2007
Purpose : Human angiotensin converting enzyme (ACE) gene shows an insertion/deletion polymorphism in 16 intron, and three genotypes are determined by whether a 287 bp fragment of the DNA is present or not; II, ID and DD genotype. DD genotype has been suggested as a risk factor of chronic nephrotic disease such as IgA nephropathy and diabetic nephropathy, various cardiovascular...
1828G>A polymorphism of the UDP-glucuronosyltransferase gene (UGT1A1) for neonatal hyperbilirubinemia in Koreans
Ja Young Kim, Mi Yeoun Kim, Ji Sook Kim, Eun Ryoung Kim, Seo Hyun Yoon, Hee Jae Lee, Joo Ho Chung
Clin Exp Pediatr. 2006;49(1):34-39.   Published online January 15, 2006
Purpose : The incidence of neonatal hyperbilirubinemia is twice as high in East Asians as in Caucasians. However, its metabolic basis has not been clearly explained. The UDP-glucuronosyltransferase gene(UGT1A1) mutation was found to be a risk factor of neonatal hyperbilirubinemia. We studied whether neonatal hyperbilirubinemia is associated with the 1828G>A(rs 10929303) polymorphism of the UGT1A1 gene, which encodes for a...
The Association of Neonatal Hyperbilirubinemia with UGT1A1 and CYP1A2 Gene Polymorphism in Korean Neonates
Hoon Kang, Jun Ho Lim, Ji Sook Kim, Eun Ryoung Kim, Sung Do Kim, Hee Jae Lee, Joo Ho Chung
Clin Exp Pediatr. 2005;48(4):380-386.   Published online April 15, 2005
Purpose : The incidence of nonphysiologic neonatal hyperbilirubinemia is twice as high in East Asians as in whites. Recently, UGT1A1 mutation was found to be a risk factor for neonatal hyperbilirubinemia. In congenitally-jaundiced Gunn rats, which lack expression of UDP-glucuronosyltransferase, alternative pathways can be stimulated by inducers of CYP1A1 and CYP1A2 enzymes. CYP1A2 plays a major role in bilirubin degradation...
Polymorphism of UDP-glucuronosyltransferase Gene(UGT1A1) of Neonatal Hyperbilirubinemia in Korea
Ki Woong Hong, Hoon Kang, Soo Kim, Ji Sook Kim, Eun Ryoung Kim, Hee Jae Lee, Sheng-Yu Jin, Joo Ho Chung
Clin Exp Pediatr. 2004;47(1):18-23.   Published online January 15, 2004
Purpose : The incidence of neonatal hyperbilirubinemia is twice as high in East Asians as in whites and its metabolic basis has not been clearly explained. Recently, UDP-glucuronosyltransferase gene (UGT1A1) mutation was found to be a risk factor of neonatal hyperbilirubinemia in Japanese and Taiwanese Chinese. We studied whether neonatal hyperbilirubinemia is associated with mutation of UGT1A1, which is a...
Diurnal Variation in Serum Bilirubin Concentration of Normal Newborn Infant
Cheol Am Kim, Jin Geong Jeong, Eui Tak Oh, Hong Ja Gang, Gil Seu Kim
Clin Exp Pediatr. 1998;41(1):33-37.   Published online January 15, 1998
Purpose : We investigated whether there are independent intradaily changes in bilirubin levels in normal neonates. Methods : During the period of January 1996 till July 1996, 100 healthy newborn infants were studied for at least 3 consecutive days. Starting from the third day of life, consistent intradaily changes of bilirubin concentration were observed. And obstetric history, birth history, weight change at 3 days were...
Oral Agar and Conventional Phototherapy Combination in the Treament of Neonatal Hyperbilirubinemia
Seong Wha Kim, Ji Hyang Doh, Jin Woo Choi, Min Hyang Kim, Ji Won Lee, Sung Taek Kim
Clin Exp Pediatr. 1997;40(7):931-938.   Published online July 15, 1997
Purpose : Neonatal jaundice is one of the most common problems in our country leading to hospitalization. Agar is low cost, low risk, and easily fed orally; it can bind bilirubin in the intestine, decreasing its enterohepatic circulation, thereby decreasing serum bilirubin levels. At present, however, the effectiveness of agar in the prevention and treament of neonatal jaundice is quite conflicting and controversy. Recently we...
High-Dose Intravenous Immune Globulin Therapy for Hyperbilirubinemia Caused by ABO Incompatibility
Dong Sung Kim, Dong Un Kim, Ji Whan Han, Sung Soo Whang, Kyung Yil Lee, Man Kyu Yang
Clin Exp Pediatr. 1993;36(8):1073-1079.   Published online August 15, 1993
Four newborn infants with hyperbilirubinemia, caused by ABO blood group incompatibility, were treated with high-dose intravenous immune globulin (IVIG). As soon as the diagnosis was clinically suspected, these infants received conventional treatment including phototherapy and were monitored closely for bilirubin levels. When bilirubin concentrations reached the risk point in spite of pjototherapy, IVIG was given at a dose of 1g/kg for...

The isoimmune hemolytic diseases of the newborn due to minor blood group are characterized by the abnormal titer of minor group antibody in mother’s serum and neonatal progressive jaundice caused by isoimmune hemolytic anemia. This report present the clinico-hematologic features of six cases of hemolytic diseases of newborn due to minor blood group isoimmunization who were admitted to the Kyung Hee university Hospital and presented...

We have studied the hemoglobin level and. leukocyte count of 23 fullterm and 1 premature jaundiced babies soon after exchange transfusion and daily thereafter until 7 days. The resixlts are: 1) One exchange transfusion was enough in 16 patients but 8 were required more than 2times of exchange transfusion. The maximum is 6 times. 2) The postnatal age was...
A Case-Control Study on the Factors Influencing Neonatal Hyperbilirubinemia.
Kwang Ho Meng, Won Chul Lee, Kyung Tai Whang
Clin Exp Pediatr. 1982;25(2):136-140.   Published online February 28, 1982
Neonatal Hyperbilirubinemia is increasing in frequency and there have been suggestions that this may be due to some change in factors involved in delivery. In this study, among numerous hypothesized factors, maternal age, gestational age, birth weight, birth order, and methods of delivery were tested if there were statistical associations between these factors and occurance of neonatal hyperbilirubinemia. For the...
