目的 评估高胆红素血症新生儿的体液免疫状态及其进行交换输血治疗(换血术)前后的血清免疫球蛋白(Ig)水平变化情况,了解换血术对新生儿血清Ig的影响.方法 对62例高胆红素血症新生儿进行换血治疗,治疗前后分别测定其血清Ig(IgG、IgA、IgM)水平,并依据病因分成ABO溶血病组、Rh溶血病组、脓毒症组和其他组进行分析.结果 1.换血术前:ABO溶血病组、Rh溶血病组IgG水平均显著高于脓毒症组及其他组(Pa<0.01),各组间IgA、IgM水平无明显差异(Pa>0.05).2.换血术后ABO溶血病组、Rh溶血病组IgG水平均较换血前显著下降(Pa<0.05);其他组及脓毒症组IgG水平均较换血前升高,但差异无统计学意义(P=0.387,0.091).3.换血后4组IgA水平均较换血前升高,且其他组、ABO溶血病组和Rh溶血病组治疗前后比较差异有统计学意义(Pa=0.000),脓毒症组治疗前后无统计学意义(P=0.185).4.换血后4组IgM水平均较换血前升高,其他组、ABO溶血病组和Rh溶血病组治疗前后比较均有统计学意义(Pa<0.05),但脓毒症组治疗前后无统计学意义(P=0.081);且其他组、ABO溶血病组和Rh溶血病组各组间治疗后比较有统计学意义(P<0.01).结论 1.新生儿溶血病患儿术前血清IgG水平较高,换血术能迅速降低溶血病患儿血IgG水平,提升患儿血IgA、IgM水平;2.换血术对脓毒症患儿血清IgG、IgA、IgM的水平无明显影响;3.换血术能提高其他高胆红素血症患儿血清IgA、IgM水平,但对血清IgG水平无明显影响. 相似文献

目的了解产科高危因素对新生儿高胆红素血症(HB)发病情况的影响,为早期防治HB提供依据。方法回顾性调查2004年1月~2006年12月本院产科出生并因病转入儿科住院治疗新生儿HB542例,其中明确新生儿科疾病299例(55.17%),出生前有产科因素320例(59.04%;部分病例同时有明确新生儿科疾病),未明病因76例(14.02%)。排除有明确新生儿科疾病后,余192例HB列为统计分析对象,采用Logistic多因素回归分析围生期产科相关危险因素。结果胎膜早破、宫内窘迫、羊水粪染、高龄初产、剖宫产、生后体质量明显下降、母乳缺乏、肝内胆管淤积症、妊娠期高血压、胎龄及母亲产前使用催产素、镇静剂是新生儿高胆红素血症的主要危险因素。结论加强围生期管理,积极处理孕期疾病,严格掌握剖宫产指征,减少人为催产比例,加强高危妊娠、高危分娩监测,积极喂养是有效地控制HB发生的重要因素。 相似文献

Risk factors for severe hyperbilirubinemia in neonates 总被引:13,自引:0,他引:13
The incidence of severe neonatal hyperbilirubinemia is higher in Asians than in whites. A case-control study was designed to investigate the effects of eight known risk factors [breast feeding, ABO incompatibility, premature birth, infection, cephalohematoma, asphyxia, glucose-6-phosphate dehydrogenase (G6PD) deficiency, and variant UDP-glucuronosyltransferase 1A1 (UGT1A1) gene] and a suspicious analog [organic anion transporter 2 (OATP 2) gene] on severe hyperbilirubinemia in Taiwanese neonates. The 72 study subjects and 100 hospital control subjects consisted of neonates with peak serum bilirubin levels > or =342 microM and <256.5 microM, respectively. The PCR-restriction fragment length polymorphism method was applied to detect the UGT1A1, OATP 2, and G6PD genes. The results of multivariate logistic regressions, adjusted for covariates, revealed odds ratios (ORs) of 4.64 [95% confidence interval (CI): 2.25-9.57; p < 0.001], 3.36 (95% CI: 1.54-7.35; p=0.002), and 3.02 (95% CI: 1.30-6.99; p=0.010) for neonates who were fed with breast milk, and carry the variant UGT1A1 gene at nucleotide 211 and the variant OATP 2 gene at nucleotide 388, respectively. The ORs, adjusted for covariates, for the other six risk factors were not statistically significant. The ORs in neonates who had one, two, and three significant risk factors were 8.46 (95% CI: 2.75-34.48; p < 0.001), 22.0 (95% CI: 5.50-88.0; p < 0.001), and 88.0 (95% CI: 12.50-642.50; p < 0.001), respectively. In conclusion, neonates who carry the 211 and 388 variants in the UGT1A1 and OATP 2 genes, respectively, as well as feed with breast milk are at high risk to develop severe hyperbilirubinemia. 相似文献

Genetic polymorphisms in Thai neonates with hyperbilirubinemia 总被引:1,自引:0,他引:1
Sariya Prachukthum Pracha Nunnarumit Paneeya Pienvichit Ampaiwan Chuansumrit Daunthida Songdej Saowanee Kajanachumpol Samart Pakakasama Suradej Hongeng 《Acta paediatrica (Oslo, Norway : 1992)》2009,98(7):1106-1110
Aim: Polymorphisms of the UGT1A1 gene, SLCO1B1 gene and GST gene have been associated with significant hyperbilirubinemia. We would like to determine whether the variation of UGT1A1 gene, SLCO1B1 gene and GST gene may play a significant role in neonatal hyperbilirubinemia in Thai infants.
Methods: Ninety-one study subjects (hyperbilirubinemic group) and 86 control subjects were studied.
Results: The cause of neonatal hyperbilirubinemia could not be identified in 64 infants (70.3%), ABO blood group incompatibility in 14.3% and Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency in 8.8%. In the hyperbilirubinemic group, 23 of 91 (25.3%) infants demonstrated variant of UGT1A1 at nucleotides (nt) 211 as compared to 6 of 86 (7%) in the control group (p = 0.001). There were no significant differences between groups in the variants UGT1A1 at nt 686, SLCO1B1 gene at nt 388, 463 and the GST gene. Male infants with G-6-PD deficiency were associated with hyperbilirubinemia (21.2% vs. 4.8% in the control group) with an odds ratio (OR) of 5.37 (p =0.02). The relationship between G-6-PD and variant in UGT1A1 gene at nt 211 could not be determined.
Conclusion: Thai infants with variant in the UGT1A1 at nt 211 or with G-6-PD deficiency are at higher risk for developing neonatal hyperbilirubinemia. 相似文献

Objective To assess the utility of 24 and 48 hours transcutaneous bilirubin (TcB) index for predicting subsequent significant hyperbilirubinemia
in healthy term neonates.
Methods TcB indices were obtained for healthy, breastfed, term AGA newborns at 24 ± 2, 48 ± 2 and subsequently at intervals of 24
hours. Neonates with illness, on treatment and positive Direct Coomb’s test were excluded. Serum bilirubin levels were obtained
whenever indicated. Neonates having serum bilirubin ≥ 17 mg/dL were considered as significant hyperbilirubinemia. The 24 and
48 hour TcB indices, as risk predictors for such hyperbilirubinemia were determined.
Results Study included 461 healthy term neonates. The mean birth weight was 2949 (± 390) gm and mean gestation of 38.6 (± 1.1) weeks.
Eight one (17.6%) had significant hyperbilirubinemia. Of 461, 135 (29.3%) had TcB index < 5 at 24 hours and 200 (43.3%) had
index < 8 at 48 hours. None of them had later hyperbilirubinemia (100 % negative predictive value). Significant hyperbilirubinemia
increased from 8.1 % to 76.4% as 24 hours TcB index raised from 5 to 9 and from 10.4 % to 83.7% as 48 hour TcB index raised
from 8 to 11. Sensitivity and specificity were optimised at TcB value of 7(risk: OR=26.8, 95%Cl: 13.9–51.5) at 24 hours and
10 (risk: OR= 17.1, 95%Cl 8.9–32.9) at 48 hours. C-statistics for 24 and 48 hour measurements are 0.838 and 0.836 respectively.
Conclusion The 24 and 48 hour TcB indices are predictive for subsequent significant hyperbilirubinemia and can guide clinician in early
discharge of healthy term newborns. 相似文献
