Ma H, Sheng Z, Xu J. The Severity of Direct Antiglobulin Test Negative ABO Hemolytic Disease of Newborn: A Retrospective Analysis at a Tertiary Children's Hospital. Indian J Hematol Blood Transfus 2024; 40:261-267. [PMID: 38708147 PMCID: PMC11065802 DOI: 10.1007/s12288-023-01689-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Accepted: 08/10/2023] [Indexed: 05/07/2024] Open
Abstract
This study aimed to evaluate the severity of ABO hemolytic disease of newborn (ABO-HDN) with negative direct antiglobulin test (DAT), which was identified by elution test. We retrospectively reviewed the clinical records of all neonates admitted with the diagnosis of neonatal hyperbilirubinemia requiring phototherapy or exchange transfusion. Neonates were divided into four groups according to their immunohematology test results. Then their essential laboratory results, magnetic resonance image (MRI), brainstem auditory evoked potential (BAEP) findings, and rate of exchange transfusion were compared between different groups. We found that neonates in ABO-HDN with negative DAT group developed jaundice faster and anaemia more severely than those in the non-HDN group. Although they might get less severe anaemia than neonates in ABO-HDN with positive DAT group and the Rh-HDN group, neonates in ABO HDN with negative DAT group might develop jaundice as quickly as the latter two groups. As to MRI and BAEP findings, there were no significant differences among the four groups. The rate of exchange transfusion in ABO-HDN with negative DAT group was higher than that in the non-HDN group but lower than that in ABO-HDN with positive DAT group, though without statistical significance. It suggested that in the presence of clinical suspicion of ABO-HDN with negative DAT result, the elution test should be added to rule out or confirm the diagnosis to help prevent the morbidity from hyperbilirubinemia.

Abstract
BACKGROUND Bilirubin neurotoxicity involves a spectrum of varying severity that could result in adverse long-term sequelae. AIMS To compare the neurodevelopmental outcome of full-term neonates who underwent exchange transfusion with those who did not. STUDY DESIGN A retrospective cohort study. SUBJECTS This study included a retrospective review of records of sixty neonates who were matched in admission ages and serum bilirubin levels and the comparison groups were those who received an exchange transfusion (n = 30) versus those where exchange transfusion was planned, but the bilirubin levels dropped sufficiently during the period where the exchange blood was being prepared (n = 30). History, clinical examination, and laboratory investigations were documented. OUTCOME MEASURES Neurodevelopmental outcome, at 6 months of age, using Bayley scales of infant development was assessed. RESULTS The exchange group had statistically significant lower cognitive scores (p-value 0.005). The higher the rate of bilirubin decline, the better the language and motor scores in the phototherapy group (p-values 0.020 and 0.024 respectively). Infants with longer duration to exchange transfusion had lower cognitive, language, and motor scores (p-values 0.01, 0.001, and 0.003 respectively). CONCLUSIONS Slower rates of bilirubin decline and longer duration before intervention increase the chances of adverse neurodevelopmental outcomes.

Abstract
OBJECTIVE To compare the association of unbound bilirubin (UB), total serum bilirubin (TSB), and bilirubin:albumin molar ratio (BAMR) with acute bilirubin encephalopathy (ABE), as assessed by bilirubin-induced neurologic dysfunction (BIND) score, in infants with significant hyperbilirubinemia (TSB ≥20 mg/dL or underwent exchange transfusion). STUDY DESIGN In this prospective cohort study, infants ≥34 weeks of gestational age with significant hyperbilirubinemia during the first 2 postnatal weeks were eligible, unless they had craniofacial malformations, chromosomal disorders, TORCH (toxoplasmosis, other infections, rubella, cytomegalovirus and herpes simplex) infections, surgery, or a family history of congenital deafness. TSB, serum albumin, and UB were measured at hospital admission using the colorimetric, bromocresol green, and modified peroxidase method, respectively. Infants were evaluated on admission for ABE using a standardized neurologic examination and assigned a BIND score by trained physicians. Infants with a total BIND score of 0 were deemed to not have ABE, whereas those with a score ≥1 were deemed to have ABE. RESULTS A total of 151 infants were studied, among whom 37 (24.5%) had ABE. Of these, 19 had mild ABE (BIND score 1-3) and 18 had moderate-to-severe ABE (BIND score 4-9). On logistic regression, UB, but not TSB or BAMR, was associated with ABE (aOR 1.64; 95% CI 1.17-2.3). On ordered logistic regression, UB, but not TSB or BAMR, was associated with severity of ABE (aOR 1.76; 95% CI 1.28-2.4). CONCLUSIONS Our findings of the association between UB and ABE indicate that BIND scoring may be useful for evaluation of ABE in infants ≥34 weeks of gestational age.

[PMID: 38312544 PMCID: PMC10835243 DOI: 10.1016/j.heliyon.2024.e24838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 01/04/2024] [Accepted: 01/15/2024] [Indexed: 02/06/2024] Open
Abstract
Background Neonatal jaundice is one of the most prevalent problems, affecting over a million newborns globally every year. It increases the likelihood of hospitalization, lifetime disability, and death, particularly in low and middle-income countries. Despite its impact and diverse risk factors, neonatal jaundice remains underappreciated in developing nations such as Ethiopia. As a result, this study aimed to determine the magnitude and associated factors of jaundice in newborns admitted to public hospitals in south Ethiopia. Methods A facility-based cross-sectional study was conducted among 417 newborns from October 1, 2020, to April 30, 2021. The data was collected using pretested interviewer-administered questionnaire and checklist. Jaundice and its severity were assessed using the physician's diagnosis and the Kramer scale. Open data kit tools and Stata version 16.0 were used for data collection and analysis, respectively. Bivariable and multivariable analyses were used to identify factors associated with neonatal jaundice. An odds ratio with a 95 % confidence interval was used to assess the direction and strength of the association. Results Out of the newborns, 24.46 % [95 % CI: 20.42-28.88] encountered neonatal jaundice. Being male [AOR: 1.81, 95 % CI: 1.06, 3.12], birth injuries [AOR: 3.01, 95 % CI: 1.27, 7.12], perinatal asphyxia [AOR: 2.10, 95 % CI: 1.18, 3.76], hyaline membrane disease [AOR: 2.16, 95 % CI: 1.16, 4.00], sepsis [AOR: 3.30, (95 % CI: 1.67, 6.54], the combined effect of low birth weight and prematurity [AOR: 1.88, 95 % CI: 1.06, 3.35], and maternal alcohol abuse during pregnancy [AOR: 2.46, 95 % CI: 1.02, 5.94] were significantly associated with neonatal jaundice. Conclusion The burden of neonatal jaundice was high in the hospitals studied. Early detection and treatment of neonatal problems, counseling pregnant women to avoid consuming any level of alcohol, strict monitoring of labor and delivery, improving antenatal care utilization, and pre-discharge universal bilirubin screening of newborns are essential to reduce the incidence and complications of jaundice. The findings of this study will be used as input to initiate interventions and conduct further studies.

Clinical and genetic risk factors associated with neonatal severe hyperbilirubinemia: a case-control study based on the China Neonatal Genomes Project. Front Genet 2024; 14:1292921. [PMID: 38274110 PMCID: PMC10808734 DOI: 10.3389/fgene.2023.1292921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 12/19/2023] [Indexed: 01/27/2024] Open
Abstract
Objective: We aimed to investigate the clinical and genetic risk factors associated with neonatal severe unconjugated hyperbilirubinemia. Methods: This was a retrospective, 1:1 matched, case-control study. We included 614 neonates diagnosed with severe unconjugated hyperbilirubinemia (serum total bilirubin level ≥425 μmol/L or serum total bilirubin concentration that met exchange transfusion criteria) from the China Neonatal Genomes Project in Children's Hospital of Fudan University. Clinical exome sequencing data were analyzed using a data analysis pipeline of Children's Hospital of Fudan University. The factors associated with severe unconjugated hyperbilirubinemia were assessed using univariable and multivariable logistic regression analyses. Interaction analyses were examined between clinical and genetic risk factors. Results: ABO/Rh incompatibility hemolysis (odds ratio [OR] 3.36, 95% confidence interval [CI] 2.32-4.86), extravascular hemorrhage (OR 2.95, 95% CI 2.24-3.89), weight loss (OR 5.46, 95% CI 2.88-10.36), exclusive breastmilk feeding (OR 3.56, 95% CI 2.71-4.68), and the homozygous mutant of UGT1A1 211G>A (OR 2.35, 95% CI 1.54-3.59) were all identified as factors significantly associated with severe unconjugated hyperbilirubinemia. The presence of UGT1A1 211G>A mildly increased the risk of severe unconjugated hyperbilirubinemia caused by ABO/Rh incompatibility hemolysis (OR 3.98, 95% CI 2.19-7.23), although the effect is not statistically significant. Conclusion: ABO/Rh incompatibility hemolysis, extravascular hemorrhage, weight loss, exclusive breastmilk feeding, and the homozygous mutant of UGT1A1 211G>A were found to be risk factors for severe unconjugated hyperbilirubinemia. Clinical factors remain the most crucial and preventable determinants in managing severe unconjugated hyperbilirubinemia, with a minimal genetic contribution. The establishment of preconception care practices and the reinforcement of screening for the aforementioned risk factors are essential steps for preventing severe unconjugated hyperbilirubinemia.

Abstract
Given the prevalence of jaundice in newborns, and the consequences of untreated hyperbilirubinemia, the long-awaited revised clinical practice guidelines for hyperbilirubinemia were finally released in August 2022 by the American Academy of Pediatrics as an update to the 2004 guidelines on the same topic. As new evidence and data become available, it is important for pediatricians and neonatologists to re-assess their clinical decision-making over time to ensure that patients are receiving the best care possible. With improvements in medical equipment and medical technology, and growing concerns about the overtreatment of hyperbilirubinemia, the newest clinical practice guidelines attempt to tackle the prevention, risk assessment, monitoring, and treatment of hyperbilirubinemia with these things in mind.

Abstract
All national and international pediatric guidelines universally prescribe meticulous bilirubin screening for neonates as a critical measure to mitigate the incidence of acute bilirubin encephalopathy (ABE) and Kernicterus. The prevailing gold standard for jaundice detection in neonates necessitates invasive blood collection, followed by subsequent biochemical testing. While the invasive procedure provides dependable bilirubin measurements and continues to be the sole gold standard diagnostic method for assessing bilirubin concentration. There exists a pressing need to innovate non-invasive screening tools that alleviate the sampling stress endured by newborns, mitigate iatrogenic anemia, and expedite the turnaround time for obtaining results. The exploration of non-invasive modalities for bilirubin measurements is gaining momentum, driven by the overarching goal of minimizing the number of pricks inflicted upon neonates, thereby rendering screening a swift, efficient, comfortable, and dependable process. This comprehensive review article delves extensively into the array of non-invasive approaches and digital solutions that have been proposed, implemented, and utilized for neonatal bilirubin screening, with a particular emphasis on their application in low-resource settings. Within this context, the review sheds light on the existing methodologies and their practical applications, with a specific focus on transcutaneous bilirubin meters. Moreover, it underscores the prevailing open challenges in this domain and outlines potential directions for future research endeavors. Notably, the review underscores the imperative need for robust educational programs targeted at both families and healthcare personnel to expedite the process of seeking timely care for neonatal jaundice. Additionally, it underscores the necessity for the development of enhanced screening and diagnostic tools that can offer greater accuracy in clinical practice.

Abstract
BACKGROUND Abnormal methylation of N6-methyladenosine (m6A) is reportedly associated with central nervous system disorders. However, the role of m6A mRNA methylation in unconjugated bilirubin (UCB) neurotoxicity requires further research. METHODS Rat pheochromocytoma PC12 cells treated with UCB were used as in vitro models. After the PC12 cells were treated with UCB (0, 12, 18, and 24 µM) for 24 h, the total RNA m6A levels were measured using an m6A RNA methylation quantification kit. The expression of m6A demethylases and methyltransferases was detected through western blotting. We determined the m6A mRNA methylation profile in PC12 cells exposed to UCB (0 and 18 µM) for 24 h using methylated RNA immunoprecipitation sequencing (MeRIP-seq). RESULTS Compared with the control group, UCB (18 and 24 µM) treatment decreased the expression of the m6A demethylase ALKBH5 and increased the expression of the methyltransferases METTL3 and METTL14, which resulted in an increase in the total m6A levels in PC12 cells. Furthermore, 1533 m6A peaks were significantly elevated and 1331 peaks were reduced in the UCB (18 µM)-treated groups compared with those in the control group. Genes with differential m6A peaks were mainly enriched in protein processing in the endoplasmic reticulum, ubiquitin-mediated proteolysis, cell cycle, and endocytosis. Through combined analysis of the MeRIP-seq and RNA sequencing data, 129 genes with differentially methylated m6A peaks and differentially expressed mRNA levels were identified. CONCLUSION Our study suggests that the modulation of m6A methylation modifications plays a significant role in UCB neurotoxicity.

Abstract
Although bilirubin meters are still continuously widely used to screen neonatal jaundice worldwide, they still need a metrological calibration method to evaluate the measurement accuracy of these kinds of devices. In this article, the author describes a new calibration method for evaluation of the bilirubinometers measurements and evaluates the results with one of the most common statistical metrological techniques to establish and evaluate the calibration method; the techniques are x̄ and R control charts. The method mainly depends on establishing a correlation between two units, the bilirubin unit (mg/dl) and one of the metrological standard SI units, the irradiance (W/cm2), experimentally to achieve the calibration method. The study results showed that the estimated correlation coefficient of irradiance response to the bilirubinometer under test was around 0.80, which is a primary indication that the method is a considerably valid technique. In addition, the calibration method was evaluated by the statistical parameters x̄ and R control charts, and the results concluded that the variability calibration process is stable, controlled, and hence could be promisingly utilized to evaluate various bilirubinometers with satisfied accuracy and precision in measurements.

[PMID: 36248427 PMCID: PMC9556251 DOI: 10.1155/2022/1672670] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 07/18/2022] [Accepted: 08/08/2022] [Indexed: 11/10/2022]
Abstract
Objective Neonatal hyperbilirubinemia is caused by the excessive production of bilirubin and decreased excretion ability in the neonatal period. It leads to a concentration of blood bilirubin that exceeds a certain threshold. Yinzhihuang oral liquid (YZH) is a traditional Chinese medicine mixture used in the treatment of neonatal hyperbilirubinemia in China. This article systematically explores the pharmacological mechanisms by which YZH acts in the treatment of neonatal hyperbilirubinemia through network pharmacology at the molecular level. Methods We adopted the method of network pharmacology, which includes active component prescreening, target gene prediction, gene enrichment analysis, and network analysis. Results According to the network pharmacological analysis, 8 genes (STAT3, AKT1, MAPK14, JUN, TP53, MAPK3, ESR1, and RELA) may be targets of YZH in the treatment of neonatal hyperbilirubinemia. In addition, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses showed that YZH may regulate antioxidation, modulate lipid metabolism, and have anti-infective properties. Conclusion In this study, the pharmacological action and molecular mechanisms of YZH were predicted as a whole. It was found that YZH is a promising drug for treating oxidative stress due to bilirubin, as it reduces immunosuppression and helps to eliminate virus infection.

Abstract
CONTEXT Severe hyperbilirubinemia is associated with kernicterus. Informed guidance on hyperbilirubinemia management, including preventive treatment thresholds, is essential to safely minimize neurodevelopmental risk. OBJECTIVE To update the evidence base necessary to develop the 2022 American Academy of Pediatrics clinical practice guideline for management of hyperbilirubinemia in the newborn infant ≥35 weeks' gestation. DATA SOURCE PubMed. STUDY SELECTION English language randomized controlled trials and observational studies. Excluded: case reports or series, nonsystematic reviews, and investigations focused on <35-weeks' gestation infants. DATA EXTRACTION Topics addressed in the previous clinical practice guideline (2004) and follow-up commentary (2009) were updated with new evidence published through March 2022. Evidence reviews were conducted for previously unaddressed topics (phototherapy-associated adverse effects and effectiveness of intravenous immune globulin [IVIG] to prevent exchange transfusion). RESULTS New evidence indicates that neurotoxicity does not occur until bilirubin concentrations are well above the 2004 exchange transfusion thresholds. Systematic review of phototherapy-associated adverse effects found limited and/or inconsistent evidence of late adverse effects, including cancer and epilepsy. IVIG has unclear benefit for preventing exchange transfusion in infants with isoimmune hemolytic disease, with a possible risk of harm due to necrotizing enterocolitis. LIMITATIONS The search was limited to 1 database and English language studies. CONCLUSIONS Accumulated evidence justified narrowly raising phototherapy treatment thresholds in the updated clinical practice guideline. Limited evidence for effectiveness with some evidence of risk of harm support the revised recommendations to limit IVIG use.

Abstract
PURPOSE To evaluate the difference in cerebral blood flow in neonates with and without extreme unconjugated hyperbilirubinemia. METHODS Transcranial Doppler parameters of 26 full term newborns with extreme unconjugated hyperbilirubinemia (UCH) were compared to 13 postnatal age and sex matched normal healthy neonates serving as controls. Resistance index (RI), pulsatility index (PI) and peak systolic velocity (PSV) were measured in the middle cerebral, internal carotid and posterior cerebral arteries on both sides by transcranial color Doppler ultrasound. RESULTS An increase in cerebral blood flow (decreased RI, PI and increased PSV) was observed in the extreme unconjugated hyperbilirubinemia (UCH) group. There was positive correlation between total serum bilirubin level and peak systolic velocity and vice versa with resistivity and pulsatility indices. Eight neonates developed clinical features of acute bilirubin encephalopathy and showed significantly increased peak systolic velocity in the right middle cerebral artery compared to those with normal outcome. Resistivity index and pulsatility index were lower in patients managed by exchange transfusion compared to those managed with phototherapy. CONCLUSION An increase in cerebral blood flow was observed in neonates with UCH compared to those without hyperbilirubinemia. By assessing the cerebral blood flow velocity, resistivity index (RI), and pulsatility index (PI) of particular intracranial arteries, the transcranial Doppler can identify the at-risk neonates, for development of neurological affliction in extreme unconjugated hyperbilirubinemia.

Abstract
OBJECTIVE Severe neonatal hyperbilirubinemia can cause neurological disability or mortality if not effectively managed. Exchange transfusion (ET) is an efficient treatment to prevent bilirubin neurotoxicity. The purpose of this study was to evaluate outcomes in severe neonatal hyperbilirubinemia with ET and to identify the potential risk factors for poor outcomes. METHODS Newborns of ≥28 weeks of gestational age with severe hyperbilirubinemia who underwent ET from January 2015 to August 2019 were included. Demographic data were recorded and analyzed according to follow-up outcomes at 12 months of corrected age. Poor outcomes were defined as death due to bilirubin encephalopathy or survival with at least one of the following complications: cerebral palsy, psychomotor retardation (psychomotor developmental index < 70), mental retardation (mental developmental index < 70), or hearing impairment. RESULTS A total of 524 infants were eligible for recruitment to the study, and 62 infants were lost to follow-up. The outcome data from 462 infants were used for grouping analysis, of which 398 cases (86.1%) had normal outcomes and 64 cases (13.9%) suffered poor outcomes. Bivariate logistic regression analysis showed that peak total serum bilirubin (TSB) (odds ratio [OR] = 1.011, 95% confidence interval [CI] = 1.008-1.015, p = 0.000) and sepsis (OR = 4.352, 95% CI = 2.013-9.409, p < 0.001) were associated with poor outcomes of hyperbilirubinemia. Receiver operator characteristic curve analysis showed that peak TSB ≥452.9 µmol/L could predict poor outcomes of severe hyperbilirubinemia. CONCLUSION Peak TSB and sepsis were associated with poor outcomes in infants with severe hyperbilirubinemia, and peak TSB ≥452.9 µmol/L could predict poor outcomes.

Abstract
Neonatal hyperbilirubinemia (NH) is a common phenomenon. In most cases, NH is benign and transient. However, in severe NH cases, neonates can develop encephalopathy and kernicterus. With appropriate screening and treatment, these adverse sequelae can be prevented. This article aims to provide the reader with an in-depth understanding of (1) bilirubin metabolism, (2) risk factors for severe NH, (3) NH screening and treatment, (4) various etiologies of severe NH, and (5) consequences of severe, untreated NH.

Abstract
Hyperbilirubinemia is the main mechanism that causes neonatal jaundice, and genetics is one of the risk factors of hyperbilirubinemia. Therefore, this study aims to explore the correlation between two genes, UGT1A1 and SLCO1B1, and hyperbilirubinemia in Thai neonates. One hundred thirty seven neonates were recruited from Division of Clinical Chemistry, Ramathibodi Hospital. UGT1A1*28 and *6 were determined by pyrosequencing whereas, SLCO1B1 388A > G and 521 T > C genetic variants were determined by TaqMan® real-time polymerase chain reaction. Neonates carrying with homozygous (AA) and heterozygous (GA) variants in UGT1A1*6 were significantly related to hyperbilirubinemia development compared with wild type (GG; P < 0.001). To the combined of UGT1A1, total bilirubin levels in homozygous variant were higher significantly than heterozygous variant and wild type (P = 0.002, P = 0.003, respectively). Moreover, SLCO1B1 combination was significant differences between the hyperbilirubinemia and the control group (P = 0.041). SLCO1B1 521 T > C variant provide protection for Thai neonatal hyperbilirubinemia (P = 0.041). There are no significant differences in UGT1A1*28 and SLCO1B1 388A > G for the different severity of hyperbilirubinemia. The combined UGT1A1*28 and *6 polymorphism is a strong risk factor for the development of severe hyperbilirubinemia in Thai neonates. Therefore, we suggest neonates with this gene should be closely observed to avoid higher severities of bilirubin.

Clinical Assessment of Neuroinflammatory Markers and Antioxidants in Neonates with Hyperbilirubinemia and Their Association with Acute Bilirubin Encephalopathy. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9040559.

Abstract
Objective: To assess the oxidant and antioxidant status in neonates with and without hyperbilirubinemia and their association with early manifestations of acute bilirubin encephalopathy (ABE), in addition to eliciting the possible oxidative effects of phototherapy. Methods: This prospective observational study was conducted with 104 full-term newborns at Menoufia University Hospitals from January 2020 to January 2021 to help resolve the debate regarding whether bilirubin is an antioxidant. The cases group (Group I) included 52 full-term newborns (37−40 weeks) with hyperbilirubinemia during the neonatal period, while the control group (Group II) included 52 healthy, full-term age and sex-matched newborns who did not have hyperbilirubinemia. The cases group was further subdivided into Group Ia (n = 12), which included newborns who presented with neurological manifestations suggesting early ABE, and Group Ib (n = 40), which included newborns with no signs suggestive of ABE. All newborns were subjected to clinical and neurological examinations, as well as laboratory investigations. Results: Comparing the specific biological markers between the Group 1 subgroups before phototherapy, the mean plasma levels of prostaglandin-Em, prostaglandin E2, and TSB were significantly higher in Subgroup I(a) (all p < 0.05). After phototherapy, Subgroup I(a) patients had significantly higher levels of prostaglandin-Em, DSB, and TSB (p < 0.05). The biological marker levels improved after phototherapy in terms of TAC (0.811 vs. 0.903), MDA (8.18 vs. 5.13), prostaglandin-Em (37.47 vs. 27.23), prostaglandin E2 (81.09 vs. 31.49), DSB (1.21 vs. 0.55), and TSB (16.63 vs. 8.26; p-value < 0.05). Conclusion: Our study showed that an elevated level of serum bilirubin increases oxidative stress and decreases antioxidant capacity. The reduction in bilirubin levels by phototherapy is associated with a decrease in oxidative stress markers (MDA, PGEm, and PGE2) and an upsurge in TAC, highlighting the absence of oxidative stress effects arising from phototherapy. Neonates with neurological manifestations suggesting ABE had higher levels of oxidative stress markers and lower levels of total antioxidant capacity than those without.

Abstract
BACKGROUND: The baby’s delay in getting nutrition in the form of breast milk caused direct bilirubin that has reached the intestines not being bound by food and not taken out through the anus with food. In the intestine, this direct bilirubin is converted into indirect bilirubin which will be reabsorbed into the blood and this condition will cause a persistence hyperbilirubinemia condition. Hyperbilirubinemia becomes an emergency that often occurs in newborns and is characterized by the occurrence of neonatal icterus.
AIM: The purpose of this study is to analyze the effect of breast milk management on the reduction of bilirubin levels in neonatal jaundiced infants that receive phototherapy.
METHODS: The design of this study used a quasi-experimental with a pre-test and post-test design with a control group. Sampling was done by consecutive sampling and obtained 52 respondents. This research was conducted for 4 months from April 2021 to July 2021 at the Surabaya Ahmad Yani Islamic Hospital. This study was divided into two groups, namely, the intervention group which was given phototherapy therapy by maximizing breast milk management and the control group only undergoing phototherapy. Data analysis in this study used Chi-square test for univariate variables and bivariate variables using paired t-test and independent t-test.
CONCLUSIONS: Good lactation management will have a major effect on bilirubin levels in infants receiving phototherapy. Hence, there needs a motivation for the parents, especially mothers, in exclusive breastfeeding without adding formula milk or using any breast milk substitutes so that the length of care for babies with neonatal icterus is faster and the baby’s nutrition can be fulfilled in a balanced way.

Abstract
BACKGROUND Although it is known that unbound bilirubin can enter the brain, there is little evidence of its association with the development of acute bilirubin encephalopathy. Here, we investigated this potential relationship in neonates who had undergone exchange transfusion. METHODS Data from 46 newborns who underwent exchange transfusion between 2016 and 1-1 to 2018-12-31 at the First People's Hospital of Changde City in China were analyzed. The unbound bilirubin level was taken as the independent variable and the development of the acute bilirubin encephalopathy as the dependent variable. The covariates were age, birth weight, sex, red blood cell count, blood glucose, hemolytic disease, and whether the infant had received phototherapy. RESULTS The mean age and gestational age of the neonates were 146.5 ± 86.9 h and 38.6 ± 1.3 weeks [38.7(34.6-41.1) weeks] old, respectively; 52.17% were male. Binary logistic regression analysis after adjustment for covariates showed a positive association between the levels of unbound bilirubin and the development of acute bilirubin encephalopathy (odds ratio = 1.41, 95% confidence intervals 1.05-1.91, P = < 0.05). CONCLUSION There is a significant association between unbound bilirubin levels and the development of acute bilirubin encephalopathy in neonates. Further investigations are required to explore the mechanisms.

Abstract
Glucose-6-phosphate dehydrogenase (G6PD) deficiency, the most common enzymopathy worldwide, is an insufficient amount of the G6PD enzyme, which is vital to the protection of the erythrocyte. Deficient enzyme levels lead to oxidative damage, hemolysis, and resultant severe hyperbilirubinemia. If not promptly recognized and treated, G6PD deficiency can potentially lead to bilirubin-induced neurologic dysfunction, acute bilirubin encephalopathy, and kernicterus. Glucose-6-phosphate dehydrogenase deficiency is one of the three most common causes for pathologic hyperbilirubinemia. A change in migration patterns and intercultural marriages have created an increased incidence of G6PD deficiency in the United States. Currently, there is no universally mandated metabolic screening or clinical risk assessment tool for G6PD deficiency in the United States. Mandatory universal screening for G6PD deficiency, which includes surveillance and hospital-based risk assessment tools, can identify the at-risk infant and foster early identification, diagnosis, and treatment to eliminate neurotoxicity.

Abstract
BACKGROUND Available evidence suggests that our country bear great burden of severe hyperbilirubinemia. However, the causes have not been explored recently in different regions of China to guide necessary clinical and public health interventions. METHODS This was a prospective, observational study conducted from March 1, 2018, to February 28, 2019. Four hospitals in three regions of China participated in the survey. Data from infants with a gestational age ≥ 35 weeks, birth weight ≥ 2000 g, and total serum bilirubin (TSB) level ≥ 17 mg/dL (342 µmol/L) were prospectively collected. RESULTS A total of 783 cases were reported. Causes were identified in 259 cases. The major causes were ABO incompatibility (n = 101), glucose-6-phosphate dehydrogenase deficiency (n = 76), and intracranial hemorrhage (n = 70). All infants with glucose-6-phosphate dehydrogenase deficiency were from the central south region. Those from the central south region had much higher peak total bilirubin levels [mean, 404 μmol/L; standard deviation (SD), 75 μmol/L] than those from the other regions (mean, 373 μmol/L; SD, 35 μmol/L) (P < 0.001). CONCLUSIONS ABO incompatibility was the leading cause in the east and northwest regions, but cases in the central south region were mainly caused by both ABO incompatibility and glucose-6-phosphate dehydrogenase deficiency, and infants in this region had a much higher peak total bilirubin level. Intracranial hemorrhage may be another common cause. More thorough assessments and rigorous bilirubin follow-up strategies are needed in the central south region.

Abstract
Acute bilirubin encephalopathy (ABE) is still an insufficiently addressed cause of mortality and long-term morbidity in low- and middle-income countries (LMICs). This article highlights that delayed or incorrect medical advice, inaccurate bilirubin measurements as well as ineffective phototherapy are some of the relevant causes predisposing jaundiced newborns to develop extreme hyperbilirubinemia [EHB, total serum/plasma bilirubin (TB) ≥ 25 mg/dL (428 µmol/L)] and subsequent ABE. Obstacles preventing state of the art management of such infants are also discussed. Prevention of ABE cannot occur without a system-based approach tailored to suit the needs and available resources of each community. Clear set protocols, rigorous training, monitoring, and accurate documentation together with simple innovative affordable technologies that can be locally produced, are essential to observe the change desired.

Abstract
Extreme hyperbilirubinemia [EHB, total serum bilirubin (TB) >25 mg/dL]) can lead to death, acute bilirubin encephalopathy (ABE), exchange transfusion, and/or bilirubin-induced neurologic dysfunction (BIND). In specific low- to middle-income countries, an "epidemic" exists, therefore, a simplified triage management system is needed. Here, we studied a cohort of 72 infants readmitted for EHB (TB: 28.1 ± 2.5; range: 25-42 mg/dL). Of these, 15/72 (20.8%) newborns had BIND scores ≥4. Eleven (15.3%) infants with BIND scores of 4 to 6 developed moderate ABE, with 6/11 (54.5%) with TB of 28.1 ± 4.8 mg/dL having post-icteric sequelae. Eight infants (TB of 32.1 ± 3.5 mg/dL) had BIND scores >6 and developed adverse outcomes. One infant, who had Rh disease and a BIND score of 8 died. We report that the key determinants for adverse outcomes were TB >30 mg/dL and a BIND score ≥4 and may be useful for a systems approach to triage infants readmitted for EHB.

Abstract
Abstract
Background
The risk of kernicterus and BIND may be in part determined by total serum bilirubin (TSB) and by the level of non-albumin bound free bilirubin, which can easily pass the blood–brain barrier. Free bilirubin (Bf) seems a more reliable predictor for bilirubin neurotoxicity. Bilirubin/albumin ratio (B/A) is considered a surrogate parameter for Bf and has been more useful than TSB. The aim of the study is to determine whether B/A ratio correlates with BIND in newborns with severe hyperbilirubinemia and if it can predict poor neurologic outcome at 3 months follow up.
Results
This prospective study included one hundred seventeen outborn neonates ≥ 35 weeks admitted in a tertiary care neonatal intensive care unit, between May and December 2012, with TSB ≥ 20 mg/dl or necessitating exchange transfusion. Total serum bilirubin and serum albumin were done on admission and bilirubin/albumin ratio was calculated. BIND score was calculated. At the age of 3 months, 112 neonates were followed up with a detailed neurological assessment. Babies who depicted any abnormal motor examination were subjected to brain stem auditory evoked response and MRI examination. Seven infants (6.2%) presented with kernicterus on follow up. BIND scores on admission, mean TSB, and bilirubin/albumin ratio was significantly higher in kernicteric infants compared with those having normal neurological outcome at 3 months of age (P 0.001). The lowest TSB level at which kernicterus occurred in our study was 31 mg/dl. Receiver operation characteristics analysis identified B/A ratio cut off value for predicting kernicterus of 9.6 with sensitivity of 100% and specificity of 91.4%, whereas TSB cut off value of 30 mg/dl showed sensitivity of 100% and specificity of 83%.
Conclusion
B/A ratio is a strong indicator for the risk of kernicterus. B/A is more specific than TSB and should be used in the early management of neonatal hyperbilirubinemia.

Abstract
Background. Hyperbilirubinemia is prevalent and protracted in
preterm infants. This study assessed the pattern of hyperbilirubinemia in
preterm infants in Ethiopia. Methods. This study was part of
multi-centered prospective, cross-sectional, observational study that determined
causes of death among preterm infants. Jaundice was first identified based on
clinical visual assessment. Venous blood was then sent for total and direct
serum bilirubin level measurements. For this study, a total serum bilirubin
level ≥5 mg/dL was taken as the cutoff point to diagnose hyperbilirubinemia.
Based on the bilirubin level and clinical findings, the final diagnoses of
hyperbilirubinemia and associated complications were made by the physician.
Result. A total of 4919 preterm infants were enrolled into
the overall study, and 3852 were admitted to one of the study’s newborn
intensive care units. Of these, 1779 (46.2%) infants were diagnosed with
hyperbilirubinemia. Ten of these (0.6%) developed acute bilirubin
encephalopathy. The prevalence of hyperbilirubinemia was 66.7% among the infants
who were less than 28 weeks of gestation who survived. Rh incompatibility
(P = .002), ABO incompatibility
(P = .0001), and sepsis (P = .0001) were
significantly associated with hyperbilirubinemia. Perinatal asphyxia
(P-value = 0.0001) was negatively associated with
hyperbilirubinemia. Conclusion. The prevalence of
hyperbilirubinemia in preterm babies admitted to neonatal care units in Ethiopia
was high. The major risk factors associated with hyperbilirubinemia in preterm
babies in this study were found to be ABO incompatibility, sepsis, and Rh
isoimmunization.

Abstract
BACKGROUND Neonatal hyperbilirubinemia is a common medical emergency in early neonatal period. Unconjugated bilirubin is neurotoxic and can lead to lifelong neurological sequelae in survivors. OBJECTIVE To find out the association between serum bilirubin and neurodevelopmental outcome at 1 year of age using Development Assessment Scale for Indian Infants (DASII). METHODS A prospective cohort study was conducted in the Department of Pediatrics of a tertiary care institution of Central India between January 2018 and August 2019. Total 108 term healthy neonates, with at least one serum bilirubin value of >15 mg/dl, were included. Subjects were divided into three groups based on the serum bilirubin; group 1: (15-20 mg/dl) -85(78.7%) cases, group 2: (20-25 mg/dl) -17(15.7%), and group 3: (>25 mg/dl) -6(5.5%). Developmental assessment was done using DASII at 3, 6, 9, 12 months of age. RESULTS Out of 108 cases, 101(93.5%) received phototherapy, and 7(6.5%) received double volume exchange transfusion. Severe delay was observed in 5(4.6%) and mild delay in 2(1.9%) cases in the motor domain of DASII at one year. Severe delay in the motor domain was associated with mean TSB of 27.940±2.89 mg/dl and mild delay with mean TSB of 22.75±1.76 mg/dl (p = 0.001). On cluster analysis, delay was observed in locomotion 1 score in 11(13%) cases (p = 0.003) and manipulation score in 6(7.1%) cases in group 1. CONCLUSION Increased serum bilirubin was a significant risk factor for the delayed neurodevelopment in babies with neonatal jaundice. Even a moderate level of bilirubin significantly affects the developmental outcome.

Abstract
Background and Objectives: This work aimed to develop a predictive model of neonatal acute bilirubin encephalopathy. Methods: We retrospectively analyzed the data on extreme hyperbilirubinemia (EHB) newborns hospitalized in the First Hospital of Jilin University from January 1, 2012 to December 31, 2019. The demographic characteristics, pathological information, and admission examination results of newborns were collected to analyze the factors affecting acute bilirubin encephalopathy and to establish a predictive model. Results: A total of 517 newborns were included in this study, of which 102 (19.7%) had acute bilirubin encephalopathy. T1WI hyperintensity [18.819 (8.838–40.069)], mother's age > 35 years [2.618 (1.096–6.2530)], abnormal white blood cell (WBC) [6.503 (0.226–18.994)], TSB level [1.340 (1.242–1.445)], and albumin level [0.812 (0.726–0.907)] were independently associated with neonatal acute bilirubin encephalopathy (ABE). All independently associated risk factors were used to form an ABE risk estimation nomogram. The bootstrap validation method was used to internally validate the resulting model. The nomogram demonstrated good accuracy in predicting the risk of ABE, with an unadjusted C index of 0.943 (95% CI, 0.919–0.962) and a bootstrap-corrected C index of 0.900. Conclusion: A nomogram was constructed using five risk factors of ABE. This model can help clinicians determine the best treatment for neonatal hyperbilirubinemia.

Abstract
OBJECTIVE To describe the clinical experience in application of exchange transfusion therapy (ETT) in the treatment of severe neonatal hyperbilirubinemia. METHODS The clinical data and examination results of severe neonatal hyperbilirubinemia full-term cases treated by ETT were analyzed retrospectively, the etiology and risk factors of severe neonatal hyperbilirubinemia were statistically analyzed, and the statistical characteristics of the children in each etiological group and the incidence of adverse events of ETT were analyzed. RESULTS The age of jaundice, peak total bilirubin after phototherapy and ETT in 123 full-term infants were 2.0 (1.0, 3.0) days, 4.0 (2.0, 7.0) days and 4.0 (2.0, 7.0) days, respectively, of which 68 were male and 55 were female. The main pathogeny of severe neonatal hyperbilirubinemia was blood group incompatibility hemolytic disease of newborn (HDN). Age of ETT, total bilirubin after ETT, gender and BAEP results were different between ABE and non-ABE infants. Weight loss can be used as a predictor of hospitalization length. The major adverse events related to ETT were hypocalcemia, hypomagnesemia, hyponatremia and thrombocytopenia. CONCLUSIONS ETT can rapidly reduce the level of total bilirubin to prevent ABE and play an important role in the treatment of neonatal hyperbilirubinemia, but the whole process of ETT needs to be closely monitored.

Abstract
Bilirubin is the end product of heme catabolism formed during a process that involves oxidation-reduction reactions and conserves iron body stores. Unconjugated hyperbilirubinemia is common in newborn infants, but rare later in life. The basic physiology of bilirubin metabolism, such as production, transport, and excretion, has been well described. However, in the neonate, numerous variables related to nutrition, ethnicity, and genetic variants at several metabolic steps may be superimposed on the normal physiological hyperbilirubinemia that occurs in the first week of life and results in bilirubin levels that may be toxic to the brain. Bilirubin exists in several isomeric forms that differ in their polarities and is considered a physiologically important antioxidant. Here we review the chemistry of the bilirubin molecule and its metabolism in the body with a particular focus on the processes that impact the newborn infant, and how differences relative to older children and adults contribute to the risk of developing both acute and long-term neurological sequelae in the newborn infant. The final section deals with the interplay between the brain and bilirubin and its entry, clearance, and accumulation. We conclude with a discussion of the current state of knowledge regarding the mechanism(s) of bilirubin neurotoxicity.

Abstract
The study was aimed to evaluate the performance of a newly developed non-invasive and non-contact bilirubin measurement device (AJO-Neo) as an alternative to the conventional invasive biochemical method of total serum bilirubin (TSB) estimation in preterm and term neonates suffering from hyperbilirubinemia associated with risk factors, and/or undergoing phototherapy. The safety and efficacy of the device were assessed in 1968 neonates with gestational ages ranging from 28 to 41 weeks and suffering from incidences of hyperbilirubinemia. Linear regression analysis showed a good correlation between AJO-Neo and the conventional method of TSB (Pearson’s coefficient, r = 0.79). The small bias (0.27 mg/dL) and limits of agreements (− 3.44 to 3.99 mg/dL) were within the range of clinical acceptance. The device was also precise in the measurement of bilirubin levels in all subgroups of the study. The receiver operator curve (ROC), that takes account of both sensitivity and specificity of a device showed high efficacy of the device (area under the curve, AUC = 0.83) in the detection of bilirubin. While monitoring the bilirubin level during phototherapy, the device indicated promising results showing good agreement with TSB. Specificities and sensitivities of the device indicated a much higher accuracy in neonates with associated risk factors for hyperbilirubinemia. Hence, the newly developed device (AJO-Neo) is reliable in measuring bilirubin level in preterm, and term neonates irrespective of gestational or postnatal age, sex, risk factors, feeding behavior or skin color.

Abstract
To establish a clinical prediction rule for acute bilirubin encephalopathy (ABE) in term/near-term neonates with extreme hyperbilirubinemia.A retrospective cohort study was conducted between January 2015 and December 2018. Six hundred seventy-three out of 26,369 consecutive neonates with extreme hyperbilirubinemia were enrolled in this study. Data included demographic characteristics, total serum bilirubin (TSB), albumin, bilirubin/albumin ratio (B/A), direct antiglobulin test, glucose-6-phosphate deficiency, asphyxia, sepsis, acidosis. ABE was defined as a bilirubin induced neurological dysfunction score of 4 to 9. We used stepwise logistic regression to select predictors of ABE and devised a prediction score.Of the 673 eligible infants, 10.8% suffered from ABE. Our prediction score consisted of 3 variables: TSB (as a continuous variable; odds ratio [OR] 1.16; 95% confidence interval [CI], 1.02-1.31; logistic coefficient 0.15), B/A (as a continuous variable; OR 1.88; 95% CI, 1.19-2.97; logistic coefficient 0.67), and sepsis (OR 3.78; 95% CI, 1.40-10.21; logistic coefficient 1.19). Multiplying the logistic coefficients by 10 and subtracting 75, resulted in the following equation for the score: Score = 12 × (if sepsis) + 1.5 × (TSB) + 7 × (B/A) - 75. The model performed well with an area under the curve of 0.871.The risk of ABE can be quantified according to TSB, B/A, and sepsis in term/near-term neonates with extreme hyperbilirubinemia.

Extreme neonatal hyperbilirubinaemia in refugee and migrant populations: retrospective cohort. BMJ Paediatr Open 2020; 4:e000641. [PMID: 32537522 PMCID: PMC7264833 DOI: 10.1136/bmjpo-2020-000641] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Revised: 04/14/2020] [Accepted: 04/27/2020] [Indexed: 12/02/2022] Open
Abstract
OBJECTIVE To describe neonatal survival and long-term neurological outcome in neonatal hyperbilirubinaemia (NH) with extreme serum bilirubin (SBR) values. DESIGN Retrospective chart review, a one-off neurodevelopmental evaluation. SETTING Special care baby unit in a refugee camp and clinics for migrant populations at the Thailand-Myanmar border with phototherapy facilities but limited access to exchange transfusion (ET). PATIENTS Neonates ≥28 weeks of gestational age with extreme SBR values and/or acute neurological symptoms, neurodevelopment evaluation conducted at 23-97 months of age. MAIN OUTCOME MEASURES Neonatal mortality rate, prevalence of acute bilirubin encephalopathy (ABE) signs, prevalence of delayed development scores based on the Griffiths Mental Development Scale (GMDS). RESULTS From 2009 to 2014, 1946 neonates were diagnosed with jaundice; 129 (6.6%) had extreme SBR values during NH (extreme NH). In this group, the median peak SBR was 430 (IQR 371-487) µmol/L and the prevalence of ABE was 28.2%. Extreme NH-related mortality was 10.9% (14/129). Median percentile GMDS general score of 37 survivors of extreme NH was poor: 11 (2-42). 'Performance', 'practical reasoning' and 'hearing and language' domains were most affected. Four (10.8%) extreme NH survivors had normal development scores (≥50th centile). Two (5.4%) developed the most severe form of kernicterus spectrum disorders. CONCLUSION In this limited-resource setting, poor neonatal survival and neurodevelopmental outcomes, after extreme NH, were high. Early identification and adequate treatment of NH where ET is not readily available are key to minimising the risk of extreme SBR values or neurological symptoms.

Abstract
Abstract
Background
Kernicterus or bilirubin encephalopathy is a preventable cause of handicap, still occurs in our country. The aim of the current study was to assess the role of bilirubin/albumin ratio in improving the morbidity of the cases with unconjugated hyperbilirubinemia and to estimate of the cutoff value for B/A ratio for prevention and early management of bilirubin-induced neurological dysfunction.
Results
The mean gestational age was 37.1 ± 2.11 weeks; the mean age of onset of jaundice was 2.36 ± 1.04 days; the mean level of total bilirubin was 26.14 ± 7.36 mg/dl. At chosen cutoff value of bilirubin albumin ratio (B/A) 6.68, sensitivity was 82% while specificity was 64% and accuracy was 95%.
Conclusion
Bilirubin encephalopathy still occurs in significant number in our country though it is a preventable cause of handicapping. TSB is a sensitive but not a specific indicator of ABE, B/A ratio is more specific indicator of the neurologic outcome and should be utilized in the decision of early intervention.

Abstract
BACKGROUND While neonatal jaundice is generally a common benign condition; severe hyperbilirubinemia has a devastating potential for brain injury. AIM To detect the impact of severe neonatal hyperbilirubinemia on motor and mental development and its progress over time in the first year of life using the Bayley scales of infant development (BSID) II. STUDY DESIGN AND PATIENTS 177 term/near-term infants admitted for neonatal hyperbilirubinemia to the NICU of Cairo University Children's Hospital were enrolled. Clinical examination, BIND score and laboratory tests were performed at admission. Neurodevelopmental assessment using BSIDΙΙ was performed at 3 months for 147/177 neonates, and at 6 months and 12 months for 139/177 neonates. Auditory brainstem evoked potential was recorded at 3 months of age and repeated if abnormal. OUTCOME MEASURES Psychomotor (PDI) and mental developmental indices (MDI) using BSIDII. Auditory impairment using Auditory Brainstem Response (ABR). RESULTS TSB levels ranged from 10 to 63 mg/dL (179.6-1077 μmol/L) with a mean of 25.52 ± 6.5 mg/dL (436 ± 112.9 μmol/L) and BIND scores ranged from 0 to 7. By one year of age, 19/139 patients were affected; 8 had classic kernicterus, 3 had isolated auditory impairment, 1 had severe motor and mild mental delay and 7 had mild motor delay. TSB level and BIND score had positive correlation with auditory impairment and lower scores for PDI (which improved with time) and MDI (which remained stationary). Duration of exposure to hyperbilirubinemia negatively affected neurodevelopmental scores. CONCLUSION The impact of severe hyperbilirubinemia is mainly on motor and auditory impairment. Mild mental delay was detected by BSIDII in few patients. Neurodevelopmental outcome improves over time.

Abstract
Background and objectives: To evaluate the knowledge of the primary health care physicians (PHCP) in Kalubia governorate, Egypt, about the causes, diagnosis, complications, and treatment of neonatal hyperbilirubinemia (NHB). Methods: Cross-sectional survey distributed by interview to 500 physicians working in the primary health care (PHC) sector in Kalubia. Results: Out of 500 distributed surveys, 419 (84%) PHCP completed the questionnaire. They represent 174 (90%) out of 193 PHC units and centers. About 18% were males and 82% females with mean age of 28.5 ± 5.2 years, and mean duration of work was 3.3 ± 4.4 years. All of the respondents have patients with NHB in their daily practice. The knowledge of the PHCP was good in some aspects about NHB; however, it was poor and may be even hazardous in other aspects. Conclusions: Many areas of defects are detected in PHCP knowledge about NHB. Pre-service and continuous training of the PHCP about the diagnosis and management of NHB are essential.

Abstract
BACKGROUND Acute bilirubin encephalopathy (ABE) still represents a significant cause of morbidity and mortality throughout the world, especially in developing countries. We aimed to determine the prevalence of ABE based on the Johnson bilirubin-induced neurologic dysfunction (BIND) score and to describe the discharge outcomes. METHODS We prospectively studied all newborns ≥ 35 weeks with ABE by evaluating signs of mental sensorium, muscle tone, and cry patterns over 1 year. RESULTS 12% (81 out of 674) of the newborns admitted for neonatal hyperbilirubinemia had a BIND score > 1. Their admission age was 6 ± 4.1 days; total serum bilirubin (TSB) was 31.2 ± 10 mg/dL (range 17.5-75.2). Of these newborns, 40.7% and 21% had evidence of haemolysis and sepsis, respectively. Overall mortality was 9.9%; 58% of the newborns showed signs of mild-to-moderate BIND at discharge, while 32.1% survived with an apparently normal outcome. Admission BIND score was significantly correlated with admission TSB (r = 0.476, P < 0.001). Similarly, BIND score at discharge was correlated with admission TSB (r = 0.442, P < 0.001) and admission BIND score (r = 0.888, P < 0.001). The regression model showed that admission TSB (P < 0.001) and maternal illiteracy (P = 0.034) were predictors of the BIND score at admission, while admission BIND score was the best indicator of the discharge score (P < 0.001). CONCLUSIONS ABE is still a major problem in our community. Admission TSB and maternal illiteracy are good predictors of bilirubin encephalopathy at admission and discharge.

Abstract
Objective: The association between a (GT)n dinucleotide length polymorphism in the promoter region of heme oxygenase 1 (HMOX1) and the risk of neonatal hyperbilirubinemia remains controversial. This meta-analysis was, therefore, performed with aims to examine the correlation between the HMOX1 (GT)n repeat length polymorphism and neonatal hyperbilirubinemia susceptibility.Materials and methods: We searched the databases including PubMed, Embase, Cochrane Library, China national knowledge infrastructure (CNKI), and Wanfang Data, with all reviewed studies published before 28 June 2018. After the evaluation of quality, we used RevMan to perform the meta-analyses. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the effect of HMOX1 gene promoter polymorphisms on the risk of neonatal hyperbilirubinemia.Results: Seven studies, involving 584 patients with neonatal hyperbilirubinemia and 1655 controls, were included. A statistically significant association was found between the HMOX1 (GT)n repeat length polymorphism and risk of neonatal hyperbilirubinemia under the allele (allele S vs. allele L: OR = 1.81, 95% CI = 1.22-2.67, p = .003), recessive (genotype SS vs. genotypes LS + LL: OR = 1.38, 95% CI = 1.02-1.86, p = .04), dominant (genotypes SS + LS vs. LL: OR = 1.37, 95% CI = 1.01-1.76, p = .01), and homozygous genetic models (genotype SS vs. genotype LL: OR = 1.47, 95% CI = 1.02-2.11, p = .003), but not under the heterozygous genetic model. Interestingly, subgroup analysis revealed that the cutoffs of the S allele < 25 showed significant associations in any of the five genetic models (allele S vs. allele L: OR = 2.26, 95% CI = 1.68-3.05, p < .00001; genotype SS vs. genotypes LS + LL: OR = 2.56, 95% CI = 1.41-4.65, p = .002; genotypes SS + LS vs. genotype LL: OR = 1.82, 95% CI = 1.28-2.59, p = .0009; genotype SS vs. genotype LL: OR = 3.09, 95% CI = 1.50-6.36, p = .002; genotype LS vs. genotype LL: OR = 1.64, 95% CI = 1.11-2.42, p = .01); however, this association was not observed in the cutoffs of the S allele ≥25.Conclusion: The results of this study indicate that there is a significant association between the HMOX1 (GT)n repeat length polymorphism and susceptibility to neonatal hyperbilirubinemia. Newborns carrying shorter (GT)n repeats in the HMOX1 gene promoter may have a higher risk of neonatal hyperbilirubinemia.

Abstract
OBJECTIVES In preterm infants, hyperbilirubinemia is common and can impair the central nervous system. The tests available for measuring bilirubin is to collect blood from heel pricking and occasionally taking blood samples from inserted cannulas, which is painful. Therefore, there is a need to develop a non-invasive device to detect bilirubin levels in newborns and interpret the severity of jaundice. METHODS We conducted a cross-sectional study of 100 neonates. Patient data was collected between June 2015 and December 2016 from King Khalid Hospital at Al-Majma'ah, Saudi Arabia, and Alpine Hospital, Gurgaon, India. The mean gestational age of neonates was 39.0 weeks. Total bilirubin was measured using a transcutaneous bilirubinometer on the forehead and obtaining optical imaging through scanning of conjunctiva of eyes, also referred to as BiliChek and BiliCapture, respectively. Later the blood samples were obtained from these patients and tested in the laboratory to determine total serum bilirubin (TSB) levels. RESULTS The concentration of bilirubin as measured from serum, BiliChek, and BiliCapture were 10.7±2.0, 11.6±2.7, and 13.1±2.3 mg/dL, respectively. Correlation was high between TSB and BiliChek (r2 = 0.88) and between TSB and BiliCapture (r2 = 0.73). The Bland-Altman plots showed good agreement when comparing bilirubin values for both BiliChek and BiliCapture devices. Bilirubin measurement was further checked for the sensitivity and specificity and was 88.0% and 76.0% using BiliChek and 92.0% and 75.6% using BiliCapture, respectively. CONCLUSIONS The optical imaging of conjunctiva for bilirubin assay is a safe alternative to a laboratory bilirubin assay and transcutaneous bilirubinometer BiliChek.

Abstract
Bilirubin is a well-known neurotoxin in newborn infants; however, current evidence has shown that a higher serum bilirubin concentration in physiological ranges is associated with a lower risk for the development and progression of both chronic kidney disease (CKD) and cardiovascular disease (CVD) in adults. The protective mechanisms of bilirubin in CVD, CKD, and associated mortality may be ascribed to its antioxidant and anti-inflammatory properties. Bilirubin further improves insulin sensitivity, reduces low-density lipoprotein cholesterol levels and inhibits platelet activation in at-risk individuals. These effects are expected to maintain normal vascular homeostasis and thus reduce the incidence of CKD and the risks of cardiovascular complications and death. In this review, we highlight the recent advances in the biological actions of bilirubin in the pathogenesis of CVD and CKD progression, and further propose that targeting bilirubin metabolism could be a potential approach to ameliorate morbidity and mortality in CKD patients.

Abstract
Previous studies have indicated that phototherapy may be associated with childhood immune disorders in later life. The present study aimed to assess the effects of phototherapy as a risk factor in the decrease in serum globulin (GLB) levels during neonatal hyperbilirubinemia. A total of 430 full-term infants aged between 1 and 28 days, diagnosed with neonatal hyperbilirubinemia, were enrolled in the present study. Neonates with intrauterine infection, genetic abnormalities and congenital diseases were excluded from the cohort. All neonates received single-side phototherapy (halogen lamps for 12 h per day, for 3 days) and/or intravenous albumin (IVALB; 1 g/kg/day, for 2 days) and/or intravenous immunoglobulin (1 g/kg/day, for 2 days). Total serum bilirubin (TSB), albumin (ALB) and GLB levels were examined twice, on the first and fourth days of hospitalization. Neonatal TSB concentrations decreased from 299.6±83.9 to 163.6±57.6 µmol/l following 3 days of intensive treatment (P<0.001). Pearson correlative analysis indicated that TSB was significantly correlated to the GLB level (r=0.249; P<0.01), but not with ALB level. There was a significant decrease in GLB levels following phototherapy+IVALB (P<0.001). The GLB levels decreased to 2-4 g/l (10-20% compared with their baseline levels) and were markedly decreased in infants >16 days old compared with those in patients aged <16 days (P<0.001). The decreases in GLB levels observed were 21.3±4.1 to 18.5±4.2 g/l in the phototherapy group, and 23.0±3.9 to 16.6±4.5 g/l in the phototherapy+IVALB (P<0.001). The decrease in GLB levels was associated with age (95% confidence interval; -0.152, -0.016). The results demonstrated that phototherapy decreased serum GLB levels, particularly in infants aged >16 days, while additional IVALB treatment promoted the decrease, along with increased age.
