Abstract
PURPOSE Living-donor liver transplantations (LDLTs) with maternal grafts can be more successful than those with paternal grafts because of their tolerance to non-inherited maternal antigens. We reviewed LDLT patients to investigate the relationship between acute rejection and donor sex. METHODS LDLT patients between January 2010 and November 2015 were enrolled. ACR was defined by a rejection activity index of > 3. RESULTS Forty-six patients (22 males and 24 females), of whom 28 had biliary atresia, were enrolled. The median age of the patients was 2.8 years and the donor types were maternal (n = 25) and paternal (n = 21). Acute cellular rejection (ACR) was observed in 22 patients. Twelve (48%) of the 25 patients in the maternal group had at least one episode of rejection compared with 10 (48%) of the 21 in the paternal group. Among the patients with ACR, the first rejection in the maternal group occurred significantly earlier than that in the paternal group (p < 0.01). In the multivariable analysis, the only variable significantly related to the first rejection day after LDLT was donor sex (male) (p < 0.005). CONCLUSION Our results showed that maternal grafts had an effect on causing earlier ACR in LDLT.

Abstract
PURPOSE OF REVIEW Biliary atresia is a poorly understood deadly disease. Genetic predisposition factors are suspected albeit not firmly established. This review summarizes recent evidence of genetic alterations in biliary atresia. RECENT FINDINGS Whole-genome association studies in biliary atresia patients identified four distinct predisposition loci with four different genes potentially involved in the disease occurrence. Variations in these genes were searched for, but none were found in patients with biliary atresia suggesting complex mechanisms. SUMMARY Despite decades since its description and decades of intensive researches, cause of biliary atresia disease remains enigmatic. The inheritance of biliary atresia is not Mendelian. Genetic predisposition factor is one of the explored fields to explain biliary atresia pathogenicity. Biliary atresia has been associated with several inborn syndromes, chromosome anomalies, and gene polymorphisms in specific populations. Four predisposition loci encompassing genes relevant to the disease have been identified, but no pathogenic variations were found in biliary atresia patients. Few reported cases of isolated biliary atresia manifestation in the context of known genetic diseases suggest coincidental findings. Alternatives to classic genetic alterations are proposed to explain genetic predisposition in biliary atresia including noncoding and epigenetic factors. Biliary atresia is most likely related to complex traits making its genetic exploration challenging.

Abstract
Biliary atresia (BA) is a neonatal obstructive cholangiopathy characterized by a fibrosclerosing obliteration of the extrahepatic bile duct. The aim of this study was to investigate the relationship between human leukocyte antigens (HLA) and susceptibility to BA. We retrospectively analyzed 392 Japanese patients with BA and without extrahepatic anomalies who underwent living donor liver transplantations at our institute. Healthy Japanese volunteers (n = 828) served as normal controls. A significant positive association was observed between BA and HLA-DR2 (39.0% of patients vs. 30.4% of controls, odds ratio = 1.46, p = 0.029). Two-locus analyses disclosed that DR2 was not independently associated with BA, but the increased frequency of HLA-A24 and -B52 reflected the linkage disequilibrium between -A24, -B52, and -DR2. Moreover, the frequency of the haplotype HLA-A24-B52-DR2 was significantly higher in patients with BA than in the general Japanese populations described in the literature (odds ratio = 2.20, p = 0.00124). These results indicate that the gene for BA susceptibility is in close linkage disequilibrium with the HLA-A24-B52-DR2 haplotype observed in the Japanese population. We speculate that a gene at the locus close to HLA plays an important role in the pathogenesis of BA.

Abstract
We studied the human leukocytes antigens in 18 Egyptian children with biliary atresia (BA) without extrahepatic congenital malformations. There was a significant increased frequency of both B8 and DR3 (83.3% and 94.4% in patients with BA compared with 6.5% and 14.9% in the general population, respectively). Ten patients had the B8/DR3 haplotype. Our results support the hypothesis that genetic factors may play a role in susceptibility to BA.

Abstract
BACKGROUND/AIMS Extrahepatic biliary atresia remains one of the major hepatic causes of death in early childhood. Though a number of hypotheses have been developed to account for this disease, its aetiopathogenesis is poorly understood. One possibility is that this is an immune mediated disease which occurs following either toxic or infectious insult in a genetically susceptible host. Earlier studies suggested weak HLA associations but these remain unconfirmed. More recently studies of viral and autoimmune liver disease have begun to investigate non-MHC immunoregulatory gene polymorphisms. METHODS In the present study we used molecular genotyping to investigate selected HLA A, B, DRB1, DQA1, DQB1 and DPB1 alleles as well as polymorphisms in the interleukin-1 gene family, interleukin-10 promoter sequence and tumour necrosis factor alpha promoter genes in 101 children referred for surgical assessment with extra hepatic biliary atresia. Genotyping data were compared with those of 134 racially and geographically matched healthy adult health care workers. RESULTS AND CONCLUSIONS Overall there were no statistically significant differences in the distribution of any of the genes tested comparing patients and controls. These data suggest that biliary atresia is not an HLA-associated disease and that polymorphisms in both the interleukin-1 and interleukin-10 genes are not risk factors for this disease.

Abstract
A case of an association of extrahepatic biliary atresia (EHBA) and urogenital sinus (UGS) anomaly that was diagnosed as an urachal remnant antenatally is reported. Diagnostic laparoscopy of the abdominal cavity in the postnatal period was the most helpful step for making the diagnosis. Biliary atresia and urogenital sinus, which was the cause of bladder outlet obstruction, were treated successfully. To the authors' knowledge, this is the first case of this type of association introduced to the literature. J Pediatr Surg 36:635-637.

Abstract
Although the prognosis of biliary atresia has been dramatically improved in the era of liver transplantation, the Kasai operation is still the first line of surgical treatment. Successful hepatic portoenterostomy depends on early diagnosis and surgery, adequate surgical technique, prevention of cholangitis, and precise postoperative management.

Abstract
BACKGROUND In a previous study the human papillomavirus DNA was detected in seven cases of so-called idiopathic neonatal giant cell hepatitis by using nested polymerase chain reaction. The purpose of the present study was to study the prevalence and possible common causes of human papillomavirus-associated idiopathic neonatal giant cell hepatitis and extrahepatic biliary atresia. METHODS Formalin-fixed, paraffin-embedded archival tissues obtained in 18 cases of extrahepatic biliary atresia were studied for human papillomavirus DNA by nested polymerase chain reaction. In addition, in situ hybridization was performed on tissue obtained in 6 cases. RESULTS Tissue in 16 of the 18 cases studied showed amplified human papillomavirus DNA, whereas no human papillomavirus was amplified in any of 30 control samples. Main human papillomaviruses detected were types 6 and 18. Punctate intranuclear positive signals were detected in the hepatocytes after in situ hybridization for human papillomavirus DNA. CONCLUSIONS The high prevalence of human papillomavirus DNA in liver tissue in cases of extrahepatic biliary atresia suggests a strong correlation between this disorder and idiopathic neonatal giant cell hepatitis. It further suggests that this virus may be one of the causative agents in extrahepatic biliary atresia and may represent part of the spectrum of lesions associated with neonatal human papillomavirus-induced hepatic damage.
