BACKGROUND Genetic factors play an important role in neonatal hyperbilirubinemia(NH)caused by genetic diseases.AIM To explore the characteristics of genetic mutations associated with NH and analyze the correlation with genetic diseases.METHODS This was a retrospective cohort study.One hundred and five newborn patients diagnosed with NH caused by genetic diseases were enrolled in this study between September 2020 and June 2023 at the Second Affiliated Hospital of Xiamen Medical College.A 24-gene panel was used for gene sequencing to analyze gene mutations in patients.The data were analyzed via Statistical Package for the Social Sciences 20.0 software.RESULTS Seventeen frequently mutated genes were found in the 105 patients.Uridine 5'-diphospho-glucuronosyltransferase 1A1(UGT1A1)variants were identified among the 68 cases of neonatal Gilbert syndrome.In patients with sodium taurocholate cotransporting polypeptide deficiency,the primary mutation identified was Na+/taurocholate cotransporting polypeptide Ntcp(SLC10A1).Adenosine triphosphatase 7B(ATP7B)mutations primarily occur in patients with hepatolenticular degeneration(Wilson's disease).In addition,we found that UGT1A1 and glucose-6-phosphate dehydrogenase mutations were more common in the high-risk group than in the low-risk group,whereas mutations in SLC10A1,ATP7B,and heterozygous 851del4 mutation were more common in the low-risk group.CONCLUSION Genetic mutations are associated with NH and significantly increase the risk of disease in affected newborns. 展开更多

Background: SmD1-amino-acid 83-119 peptide (SmD183-119) is the major epitope of Smith (Sm) antigen, which is specific for adult systemic lupus erythematosus (SLE). The anti-SmD183-119 antibody has exhibited higher sensitivity and specificity than anti-Sm antibody in diagnosing adult SLE. However, the utility of anti-SmD183-119 antibodies remains unclear in children with SLE (cSLE). This study aimed to assess the characteristics of anti-StuD 183-119 antibody in the diagnosis of cSLE. Methods: Samples from 242 children with different rheumatological and immunological disorders, including autoimmune diseases (SLE [n = 46] and ankylosing spondylitis [AS, n = 11]), nonautoimmune diseases (Henoch-Schonlein purpura [HSP, n = 60], idiopathic thrombocytopenia purpura [n = 27], hematuria [n = 59], and arthralgia [n = 39]) were collected from Shanghai Children's Medical Center from March 6, 2012 to February 27, 2014. Seventy age- and sex-matched patients were enrolled in this study as the negative controls. All the patients' sera were analyzed for the anti-SmD 183-119, anti-Sm, anti-U 1-nRNP, anti-double-stranded DNA (dsDNA), anti-nucleosome, anti-SSA/Ro60, anti-SSA/Ro52, anti-SSB, anti-Scl-70, and anti-histone antibodies using the immunoblotting assay. The differences in sensitivity and specificity between anti-SmD183-119 and anti-Sm antibodies were compared by Chi-square test. The correlations between anti-SmD183-119 and other auto-antibodies were analyzed using the Spearman's correlation analysis. A value of P 〈 0.05 was considered statistically significant. Results: Thirty-six out of 46 patients with cSLE were found to be positive for anti-SmD183-119, while 12 patients from the cSLE cohort were found to be positive for anti-Sm. Compared to cSLE, it has been shown that anti-SmD183-119 was only detected in 27.3% of patients with AS and 16.7% of patients with HSP. In comparison with anti-Sm, it has been demonstrated that anti-StuD 183-119 had a higher sensitivity (78.3% vs. 26.1%, 2'2 = 25.1, P 〈 0.05) and a lower specificity (90.8% vs. 100%, x^2 = 13.6, P 〈 0.05) in the diagnosis of cSLE. Further analysis revealed that anti-StuD 183-119 antibodies were positively correlated with anti-dsDNA, anti-nucleosome, and anti-histone antibodies in cSLE. Moreover, it has been clearly shown that anti-SmD183-119was more sensitive than anti-Sm in discriminating autoimmune diseases from nonautoimmune disorders in patients with arthralgia or hematuria. Conclusions: Measurement of anti-SmD183-119 in patients with cSLE has a higher sensitivity and a marginally lower specificity than anti-Sin. It has been suggested that inclusion of anti-SmD183-119 testing in the integrated laboratory diagnosis ofcSLE may significantly improve the overall sensitivity in child populations. 展开更多
