OBJECTIVE: We aimed to investigate the rate of kernicterus, and physical and laboratory examination findings in hyperbilirubinemic infants with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. MATERIALS AND METHODS: This study was carried out in the Dicle University Hospital Neonatal Intensive Care Unit between June 2005 and June 2006. Out of 56 male neonates who needed an exchange transfusion due to hyperbilirubinemia, 10 with G-6-PD deficiency were included in the study. Maternal age, gestational age, route of delivery, birth weight, age at the time of admission, and treatment and outcome were recorded. Laboratory investigations included determination of direct and indirect serum bilirubin concentrations, blood group typing, direct Coomb test, complete blood count, blood smear, thyroid-stimulating hormone, T4, C-reactive protein, urine analysis, and G-6-PD level. RESULTS: Out of 56 male neonates requiring exchange transfusion, 10 had G-6-PD deficiency (18%). In G-6-PD deficient neonates, other factors known to cause hyperbilirubinemia were excluded. The mean gestational age and the mean maternal age was 38.2+/-1.0 weeks and 31.3+/-5.9 years, respectively. The mean bilirubin level was 42.1+/-13.7 mg/dL. Four patients required a second exchange transfusions, and only 1 transfusion was sufficient for the remaining patients. Five patients (55%) developed kernicterus. CONCLUSIONS: Early detection of G-6-PD deficiency in the affected newborns may be important for reducing the risk of severe hyperbilirubinemia, kernicterus, and the need for exchange transfusion. 相似文献

Isoimmune hemolytic jaundice due to ABO and Rh blood group incompatibility is an important problem in the neonatal period. Intravenous immune globulin (IVIG) treatment in isoimmune jaundice has been shown to be effective, but the response to treatment is variable. In this study, the effect of multiple doses IVIG therapy versus single dose MG therapy was investigated in 61 babies who had ABO and Rh hemolytic disease. Patients were divided into three groups. Group I received multiple dose IVIG treatment, group II received single dose MG treatment, and group III was not given any IVIG. All three groups received phototherapy. No exchange transfusion was needed in group I. The rate of exchange transfusion was 12 per cent in group II and 33 per cent in group III. Duration of phototherapy was shorter in group I than in groups II and III. It was concluded that IVIG treatment reduces the need of exchange transfusion in neonatal isoimmune hemolytic jaundice by lowering hemolysis. Multiple doses IVIG treatment appears to be better at blocking ongoing hemolysis. 相似文献

Four hundred and thirty three exchange transfusions (ET) for neonatal hyperbilirubinemia in 225 full term (Group I) and 110 premature/low birth weight (Group II) babies were analyzed. A total of 78.5% cases required one, 15.22% two, 4.8% three and 1.5% four ET. In Group I ABO HDN (35.94%), Rh HDN (10.7%), septicemia (8.9%), and G-6-PD deficiency (6.2%) were the major causes. Nearly 20% had multiple factors and in 9.3% no cause was identified. In multifactorial cases 13.3% had septicemia, 17.3% ABO HDN and 6.2% Rh HDN in various combinations. Common causes in Group II babies were septicemia (20.9%), ABO HDN (19.07%), Rh HDN (6.4%) and G-6-PD deficiency (5.4%). Nearly 8% had multifactorial etiology while 30.9% were idiopathic. Complications occurred in 20.4% Group I and 41.8% in Group II babies during ET. Procedure related mortality was 3.2/100 ET which declined to 0.9/100 ET when high risk babies were excluded. Overall mortality in babies subjected to ET was 10.6/100 ET. Cardiorespiratory arrest during procedure (30.4%), septicemia (26.1%) and kernicterus (19.6%) were the leading causes of death. Anemia (23.5% Group I and 50.9% Group II babies) and clinical septicemia (14.2% Group I and 16.4% Group II babies) were major delayed complications. 相似文献

Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency is frequently associated with neonatal hyperbilirubinemia, and sometimes kernicterus, often in the absence of any identifiable trigger or hematological evidence of hemolysis. The aim of this study was to compare the incidence and severity of, and the effect of phototherapy on, jaundice in G 6-PD-deficient vs G-6-PD-normal neonates in the Sephardic-Jewish community. Healthy term newborns, born to mothers of families stemming from geographic areas known to be "at risk" for G-6-PD deficiency, were screened for the condition and surveyed for hyperbilirubinemia. Seventy-five G-6-PD-deficient neonates formed the study group, while 266 neonates with normal levels of the enzyme formed the control group. Neonates with any other identifiable cause for jaundice were excluded. Phototherapy was commenced when the serum bilirubin levels reached 16 mg/dL (274 mumol/L) or more, and it was discontinued at 12 mg/dL (205 mumol/L) or less. Hyperbilirubinemia developed in 27 (36%) of the deficient neonates (serum total bilirubin greater than 13.9 mg/dL [238 mumol/L]), compared with 50 (18.8%) of control neonates (P = .002), while 20 (26.7%) of the study group required phototherapy, compared with 31 (11.7%) of control neonates (P = .002). Two neonates in the study group required exchange transfusion (serum bilirubin greater than 20 mg/dL [342 mumol/L]), vs 0 in the control group (not significant).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

To assess hemolysis in hyperbilirubinemic infants with ABO isoimmunization, we measured the carboxyhemoglobin (HbCO) concentrations in full-term infants with ABO isoimmunization during the first week of life. Two groups of infants, ABO compatible (n=34) and ABO incompatible (n=30), were further divided into two groups with and without hyperbilirubi-nemia. All the infants from ABO incompatible pregnancies showed a positive indirect Coombs' test. The groups with hyperbilirubinemia included infants with maximum serum total bilirubin levels about 15 mg/dL and infants treated by phototherapy or exchange transfusion. In the ABO incompatible infants, the HbCO levels in those with hyperbilirubinemia were significantly higher than in infants without hyperbilirubinemia during the first week after birth (p < 0.01 at 24, 72, 120 hours after birth, respectively). The levels of HbCO in the ABO incompatible infants with hyperbilirubinemia were significantly higher compared with the levels in the ABO compatible infants with hyperbilirubinemia (p < 0.05 at 24 hours, p < 0.01 at 72 and 120 hours after birth, respectively). HbCO measurement may facilitate the early diagnosis of hemolytic disease and the prediction of jaundice caused by ABO isoimmunization. 相似文献

Hemolytic disease in the newborn, as a cause of early jaundice, is not uncommon. This is mostly due to Rh (D), ABO incompatibility
and rarely due to other minor blood group incompatibility. The authors report two cases of Rh anti c isoimmunization presenting
as significant early neonatal jaundice within the 20 h of life. Both the babies were treated with intensive phototherapy.
One baby underwent exchange transfusion and the other required packed cell transfusion for anemia. 相似文献

Minor blood group hemolytic disease is extremely rare, since the overall potency of minor blood groups in inducing antibodies is significantly lower when compared with that of Rh (D) antigen. We hereby report a very rare case of severe neonatal anti-E hemolytic disease due to E minor blood group incompatibility. A term newborn born to a 27-year-old, gravida 3, para 3 mother was referred due to a high and increasing serum bilirubin level despite phototherapy on the 4th day of life. On admission physical examination was normal except for the jaundice, and results of the laboratory investigation demonstrated a moderate-to-severe anemia (hemoglobin 7.8 g/dl) and a severe hemolytic hyperbilirubinemia (serum total and indirect bilirubin levels 36 mg/ dl and 32.8 mg/dl, respectively; reticulocyte count 15%; and a positive direct antiglobulin test). As there was no apparent cause of the hemolytic disease such as Rh or ABO incompatibilities, further investigation (a positive indirect antiglobulin test and a positive irregular anti-E antibody in both the patient and mother, and minor blood group antigen profiles in family members compatible with E minor blood group isoimmunization) revealed the presence of anti-E hemolytic disease due to E minor blood group incompatibility. Two exchange transfusions with a 12-hour-interval were performed with minor blood group compatible fresh whole blood, and the patient was discharged in a healthy condition on the 10th postnatal day. If the most common causes of severe neonatal hemolytic disease such as Rh and ABO incompatibilities cannot be demonstrated in a newborn with significant hemolytic hyperbilirubinemia, anti-E hemolytic disease should strongly be considered in differential diagnosis. It should be kept in mind that a very severe from of minor group antibody hemolytic disease characterized by anemia and severe hyperbilirubinemia many exchange transfusions may be encountered during the course of the disease. 相似文献

Five hundred Monates referred with unconjugated hyperbilirubinemia were studied. ABO incompatibility was responsible for 22.6%
G-6PD deficiency for 18.2%, septicemia for 11.6% and Rh incompatibility for 9.8% of the cases. No cause could be established
in 35% of the cases. 74.8% of the babies were treated outside before being referred and in 5% of these the level of bilirubin
was more than 40 mg/dl. The type of treatment given included antibiotics, steroids, livertonics, phenobarbitone besides phototherapy.
10.4% of the cases had evidence of kemicterus at admission. 54% needed exchange transfusion with 27% requiring more than one.
It is recommended that a better understanding and awareness about neonatal hyperbilirubinemia be created among all doctors
coming in contact with neonates to ensure a timely referral. 相似文献

40 full-term newborn infants with erythrocyte glucose-6-phosphate dehydrogenase (G-6-PD) deficiency were used for a study concerning the effectiveness of agar per os in preventing severe hyperbilirubinemia. 20 randomly selected neonates were given agar (1 g/kg/day) orally in 4 daily doses from their 1st to their 5th day of life. 20 infants were not treated and served as controls. Three exchange transfusions were performed in the experimental as well as in the control group. According to these results, agar does not seem to be effective in preventing severe hyperbilirubinemia, which frequently occurs in newborn infants with erythrocyte G-6-PD deficiency. 相似文献

Jaundice caused by hemolysis continues to challenge practitioners caring for infants in the NICU. Bilirubin levels can rise quickly in the first days of life, and interventions must be prompt to prevent side effects related to hyperbilirubinemia. Conventional treatments such as hydration and phototherapy are common, but new studies suggest that use of intravenous immunoglobin (IVIG) as an additional treatment may prevent the need for exchange transfusion in some babies. This article presents a case study of an infant with blood-type incompatibility treated successfully with multiple doses of IVIG, discusses the pathophysiology and clinical presentation of hemolytic jaundice, and reviews current management strategies for this disease. 相似文献

Objective : This study was carried out to detect the incidence of erythrocytic Glucose-6-Phosphate dehydrogenase (G-6-PD) deficiency,
to compare the incidence of hyperbilirubinernia in G-6-PD deficient neonates as compared to G-6-PD normal neonates and to
asses the usefulness of neonatal screening for G-6-PD deficiency.Method : In a retrospective hospital based study 2,479 male and female neonates consecutively born at Indraprastha Apollo hospital
between July 1998 to June 2003 who were screened for G-6-PD levels were evaluated for the incidence of G-6-PD deficiency.Results : Incidence of G-6-PD deficiency was found to be 2.0%. Incidence in males was 283% and femle was 1.05%. The incidence of
hyperbilirubinemia was found to be 32% in G-6-PD deficient neonates which was significantly higher than the incidence of hyperbilirubinemia
in neonates with normal G-6-PD, which was 12.3% (P<0.001).Conclusion : Our data suggests that neonatal screening for G-6-PD deficiency is a useful test for preventing and early treatment of
complications associated with it. 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

In this paper the Authors report their personal experience of the use of exchange transfusion, secondary to classic indication, in the treatment of neonatal hyperbilirubinemia, in order to: 1) determine the trend over the past wears in the number of exchange transfused neonates, both from a global point of view and in relation to indications; 2) critically assess the risks, in terms of complications and mortality, correlated to exchange transfusion. Four hundred and eighty-eight neonates, who were subjected to 693 exchange transfusions in the Pediatric Clinic and Neonatal Division of the Policlinico Gemelli in Roma, were studied over a period of 15 years (1972-1986), according to the following indications: 214 cases of neonatal hyperbilirubinemia with MEN-Rh, 106 cases of neonatal hyperbilirubinemia with MEN-ABO and 168 cases of idiopathic hyperbilirubinemia. The total number of exchange transfused neonates decreased drastically from 304 in the period 1972-76 to 65 in the period 1982-86. The frequency of exchange transfused neonates because of idiopathic hyperbilirubinemia decreased significantly (p greater than 0.001), booth in comparison to the number of live births and in comparison to the number of exchange transfused neonates, probably due to the gradual introduction of phototherapy. The frequency of exchange transfused neonates with iso-Rh and iso-ABO decreased or remained stationary on account of the confirmed relative lesser efficacy of phototherapy on hemolytic jaundice. With regard to mortality and morbidity, 27 out of 488 neonates died during the neonatal period, but only 4 within six hours of exchange transfusion; the majority of those who died had a reduced gestational age and low birthweight, and were affected by a severe associated pathology. 相似文献

The influence of high-dose intravenous gammaglobulin (HDivGG) on the course of hyperbilirubinemia was investigated in three newborn infants with rhesus hemolytic disease. In addition to phototherapy and appropriate hydration all children received gammaglobulin (Polyglobulin N, Tropon-Cutter, Cologne, FRG) at a dose of 500 mg/kg body weight intravenously. All three infants showed a marked decrease in bilirubin levels after HDivGG. In two cases exchange transfusion could be avoided. In the third an elevated bilirubin level after blood exchange dropped following HDivGG, and a further exchange transfusion became unnecessary. The suspected effect of HDivGG in Rhesus incompatibility may be due to a blockade of Fc-receptors of the reticuloendothelial system, which prevents further hemolysis and bilirubin production. We propose, that the efficacy of this new mode of treatment should be evaluated in a controlled study. 相似文献
