Abstract
ABSTRACT More than 80% of newborn infants experience jaundice as a result of elevated bilirubin during the first few weeks after birth. In most cases, hyperbilirubinemia is physiologic, but persistent and extreme elevations can lead to serious long-term complications, such as kernicterus. To avoid these complications and help clinicians in the successful assessment, evaluation, and treatment of hyperbilirubinemia, the American Academy of Pediatrics updated its clinical practice guideline for neonatal hyperbilirubinemia. This article reviews the guideline and highlights significant updates, such as an elevation in the threshold for phototherapy and exchange transfusion, inclusion of gestational age, and removal of racially based norms.

[PMID: 37724614 DOI: 10.1111/jpc.16489] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 08/02/2023] [Accepted: 08/30/2023] [Indexed: 09/21/2023]
Abstract
AIM This study aimed to establish the incidence and nature of neurodevelopmental outcomes following extreme neonatal hyperbilirubinaemia in an Australian cohort. METHODS A prospective cohort study of neurodevelopmental outcomes up to 3 years of age of infants born between 2010 and 2013 at ≥34 weeks gestation, with total serum bilirubin ≥450 μmol/L and/or clinical signs of acute bilirubin encephalopathy. Outcome measures comprised neurological examination, Bayley Scales of Infant and Toddler Development, 3rd edition and Ages and Stages Questionnaire, 3rd edition. RESULTS The Australian estimated incidence of kernicterus is 0.35 per 100 000 live births. Within the follow-up cohort of 26, three children have clinical neurodevelopmental impairment: one has gross motor function classification system level 4 cerebral palsy, audiological deficiency and visual impairment; the second has gross motor function classification system level 1 cerebral palsy and the third has global developmental delay with autism spectrum disorder. Mean Bayley Scales of Infant and Toddler Development, 3rd edition scores were: cognition 10.3 (SD 1.5), receptive communication 9.4 (SD 1.8), expressive communication 9.2 (SD 2.4), fine motor 10.4 (SD 2.6) and gross motor 9.2 (SD 2.3). CONCLUSION The Australian national rate of kernicterus compares favourably with global estimates. Future preventative strategies in this context include universal neonatal hyperbilirubinaemia assessment and mandated adverse outcome reporting and investigation.

Abstract
OBJECTIVES To determine the impact of higher bilirubin thresholds on testing and treatment of healthy infants during the neonatal period. METHODS This quality improvement study included infants born at ≥35 weeks gestation and admitted to the well-baby nursery between July 2018 and December 2020. We assessed the transition from infants treated according to the 2004 AAP guidelines (pregroup) with those following the Northern California Neonatal Consortium guidelines (postgroup). We examined the proportion of infants receiving phototherapy and total serum bilirubin (TSB) assessments as outcome measures. We examined critical hyperbilirubinemia (TSB above 25 mg/dL or TSB within 2 mg/dL of threshold for exchange transfusion), exchange transfusion, and readmission for jaundice as balancing measures. We compared the differences in outcomes over time using Statistical Process Control p charts. Balancing measures between the pre and postgroups were compared using χ square tests and t-tests. RESULTS In our population of 6173 babies, there was a significant shift in the proportion receiving phototherapy from 6.4% to 4%. There were no significant changes in incidences of bilirubin >25 mg/dL (0 of 1472 vs 7 of 4709, P = .37), bilirubin within 2 mg/dL of exchange transfusion thresholds (4 of 1472 vs 5 of 4709, P = .15), exchange transfusion (0 of 1472 vs 1 of 4709, P = .70) or readmission for phototherapy (2.9% versus 2.4%, P = .30), between the 2 groups. CONCLUSIONS Higher thresholds for phototherapy treatment of neonatal hyperbilirubinemia can decrease the need for phototherapy without increasing critical hyperbilirubinemia or readmission rate.

Abstract
Neonatal jaundice (NJ) is common in newborn infants. Severe NJ (SNJ) has potentially negative neurological sequelae that are largely preventable in high resource settings if timely diagnosis and treatment are provided. Advancements in NJ care in low- and middle-income countries (LMIC) have been made over recent years, especially with respect to an emphasis on parental education about the disease and technological advancements for improved diagnosis and treatment. Challenges remain, however, due to lack of routine screening for SNJ risk factors, fragmented medical infrastructure, and lack of culturally appropriate and regionally specific treatment guidelines. This article highlights both encouraging advancements in NJ care as well as remaining gaps. Opportunities are identified for future work in eliminating the gaps in NJ care and preventing death and disability related to SNJ around the globe.

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
We examined the mental health and quality of life (QoL) outcomes and their correlates of school-aged survivors of neonatal jaundice (NNJ), hypoxic-ischemic encephalopathy (HIE), and a comparison group. The Child Behavior Checklist and the Pediatric Quality of Life Inventory were administered to assess the mental health and QoL of 375 children (134 with NNJ, 107 with HIE, and 134 comparison group) aged 6 to 12 years [Median age 9 (interquartile range 7 to 11)]. The results showed that survivors of NNJ and HIE have mental health problems and QoL similar to the comparison group. Maternal mental health was the predominant covariate of mental health and QoL in survivors of NNJ and HIE. This result could indicate that mothers with mental health problems are more likely to have children with mental health issues, but also that caring for children with these adversities may affect mental health well-being of the caregivers. There is a need for early mental health screening and psychosocial intervention for caregivers and their children to enhance both their mental health and QoL.

Abstract
OBJECTIVE To evaluate the efficacy and safety of tin mesoporphyrin (SnMP) in neonates with hyperbilirubinemia (HB) due to hemolysis. STUDY DESIGN This multicenter, placebo-controlled phase 2b study (NCT01887327) randomized newborns (35-42 weeks) with hemolysis started on phototherapy (PT) to placebo (Ctrl), SnMP 3.0 mg/kg, or SnMP 4.5 mg/kg given once IM within 30 min of initiation of PT. RESULTS In all, 91 patients were randomized (Ctrl: n = 30; 3 mg/kg SnMP: n = 30; 4.5 mg/kg SnMP: n = 31). At 48 h TSB significantly increased in Ctrl by 17.5% (95% CI 5.6-30.7; p = 0.004) and significantly decreased by -13% (95% CI -21.7 to -3.2; p = 0.013) in the 3.0 mg/kg and by -10.5% (95% CI -19.4 to -0.6; p = 0.041) in the 4.5 mg/kg group. Decreases in SnMP groups were significant (p < 0.0001) vs Ctrl. CONCLUSION SnMP with PT significantly reduced TSB by 48 h. SnMP may be useful as a treatment for HB in neonates with hemolysis.

Abstract
BACKGROUND The Millennium Developmental Goals ensured a significant reduction in childhood mortality. However, this reduction simultaneously raised concerns about the long-term outcomes of survivors of early childhood insults. This systematic review focuses on the long-term neurocognitive and mental health outcomes of neonatal insults (NNI) survivors who are six years or older. METHODS Two independent reviewers conducted a comprehensive search for empirical literature by combining index and free terms from the inception of the databases until 10th October 2019. We also searched for additional relevant literature from grey literature and using reference tracking. Studies were included if they: were empirical studies conducted in humans; the study participants were followed at six years of age or longer; have an explicit diagnosis of NNI, and explicitly define the outcome and impairment. Medians and interquartile range (IQR) of the proportions of survivors of the different NNI with any impairment were calculated. A random-effect model was used to explore the estimates accounted for by each impairment domain. RESULTS Fifty-two studies with 94,978 participants who survived NNI were included in this systematic review. The overall prevalence of impairment in the survivors of NNI was 10.0% (95% CI 9.8-10.2). The highest prevalence of impairment was accounted for by congenital rubella (38.8%: 95% CI 18.8-60.9), congenital cytomegalovirus (23.6%: 95% CI 9.5-41.5), and hypoxic-ischemic encephalopathy (23.3%: 95% CI 14.7-33.1) while neonatal jaundice has the lowest proportion (8.6%: 95% CI 2.7-17.3). The most affected domain was the neurodevelopmental domain (16.6%: 95% CI 13.6-19.8). The frequency of impairment was highest for neurodevelopmental impairment [22.0% (IQR = 9.2-24.8)] and least for school problems [0.0% (IQR = 0.0-0.00)] in any of the conditions. CONCLUSION The long-term impact of NNI is also experienced in survivors of NNI who are 6 years or older, with impairments mostly experienced in the neurodevelopmental domain. However, there are limited studies on long-term outcomes of NNI in sub-Saharan Africa despite the high burden of NNI in the region. TRIAL REGISTRATION Registration number: CRD42018082119.

Abstract
OBJECTIVE To determine the incidence and etiology of extreme neonatal hyperbilirubinemia, defined as total serum bilirubin (TSB) ≥450 µmol/L, and kernicterus spectrum disorder (KSD) in Denmark between 2000 and 2015. STUDY DESIGN We identified all infants born between 01.01.2000 and 31.12.2015 with TSB ≥450 µmol/L, ratio of conjugated to TSB <0.30, gestational age ≥35 weeks, and postnatal age ≤4 weeks, using Danish hospitals' laboratory databases. RESULT We included 408 infants. The incidence of extreme neonatal hyperbilirubinemia among infants with gestational age ≥35 weeks was 42/100,000 during the study period with a seemingly decreasing incidence between 2005 and 2015. Twelve of the 408 infants developed KSD, (incidence 1.2/100,000) Blood type ABO isohemolytic disease was the most common explanatory etiology. CONCLUSIONS Our study stresses the importance of a systematic approach to neonatal jaundice and ongoing surveillance of extreme neonatal hyperbilirubinemia and KSD.

Abstract
IMPORTANCE Treatment of jaundiced newborns with subthreshold phototherapy (phototherapy given to newborns with bilirubin levels below those recommended in American Academy of Pediatrics [AAP] guidelines) is common. However, the use of subthreshold phototherapy may have risks and increase costs, and, to date, it has not been systematically studied in newborns. OBJECTIVES To estimate the efficacy of subthreshold phototherapy for newborns with total serum bilirubin (TSB) levels from 0.1 to 3.0 mg/dL below the appropriate AAP phototherapy threshold during the birth hospitalization in preventing readmissions for phototherapy, and to identify predictors of readmission for phototherapy. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study of 25 895 newborns born at 35 or more weeks' gestation, born in 1 of 16 Kaiser Permanente Northern California hospitals from January 1, 2010, through December 31, 2014, with at least 1 TSB level from 0.1 to 3.0 mg/dL below the appropriate AAP phototherapy threshold and not exceeding the threshold during the birth hospitalization. Data were analyzed from November 1, 2015, to November 28, 2017. EXPOSURE Subthreshold phototherapy during the birth hospitalization. MAIN OUTCOMES AND MEASURES Readmission for phototherapy. RESULTS Among 25 895 newborns with qualifying TSB levels from 0.1 to 3.0 mg/dL below the appropriate AAP phototherapy threshold, 4956 (19.1%) received subthreshold phototherapy and 241 of these (4.9%) were readmitted for phototherapy compared with 2690 of 20 939 untreated newborns (12.8%) (unadjusted odds ratio [OR], 0.35; 95% CI, 0.30-0.40). In a logistic regression model, adjustment for confounding variables, including gestational age, race/ethnicity, formula feedings per day, and the difference between the TSB level and the phototherapy threshold, strengthened the association (OR, 0.28; 95% CI, 0.19-0.40). Estimated numbers needed to treat ranged from 60.8 in the lowest quintile of predicted risk to 6.3 in the highest quintile. Newborns who received formula feedings had lower adjusted odds of readmission for phototherapy compared with exclusively breastfed newborns (OR, 0.58; 95% CI, 0.47-0.72 for >0 to <2 formula feedings per day; OR, 0.24; 95% CI, 0.21-0.27 for ≥6 formula feedings per day). Subthreshold phototherapy was associated with a 22-hour longer length of stay (95% CI, 16-28 hours). CONCLUSIONS AND RELEVANCE Subthreshold phototherapy during the birth hospitalization is effective in preventing readmissions for phototherapy; however, for each readmission prevented, many newborns require phototherapy who would otherwise not need it.

Abstract
This study aimed to establish norms for the modified Chinese version of the Autism Spectrum Rating Scale (ASRS). Participants were recruited from Shanghai, Harbin, Guangzhou, and Changsha, China, and their parents and teachers were invited to complete the Chinese Parent version and the Teacher version of the ASRS. In both versions, boys had significantly higher sub-scale scores and total score (T-score) by 1–3 and 4–5 points respectively, than girls (both P < 0.001). Age had weak correlations with some sub-scores and the T-score (r ranged from −0.1859 to 0.0738), and some reached significance (P < 0.03). The correlations appeared stronger and were more common in females. The T-score based on Chinese norms ideally correlated with the score based on the United States norms in boys and girls for both versions. Norms for the Chinese version of the ASRS for children aged 6–12 years are proposed and may be helpful for screening individuals with autism spectrum disorders from the general population of children.

Abstract
AIM This study examined maternal and pregnancy risk factors for haemolytic and nonhaemolytic neonatal jaundice in a large population-based cohort study. METHODS We conducted a cohort study of 1 019 220 singleton live births from the Swedish medical birth register from 1987 to 2002, using information on neonatal jaundice and maternal and pregnancy characteristics. Diagnoses of gestational hypertensive disorders were obtained by linkage to the national inpatient register. Multivariate logistic regression analysis provided odds ratios for the risk factors of both forms of jaundice. RESULTS A total of 6057 (0.6%) births were affected by haemolytic jaundice and 36 869 (3.6%) by nonhaemolytic jaundice. The strongest risk factors for haemolytic jaundice were maternal alloimmunisation, blood group O and neonatal jaundice in older siblings. For nonhaemolytic jaundice, the strongest risk factors were preterm birth, neonatal jaundice in older siblings, maternal origin from East or South-East Asia and maternal obesity. We estimated that 13% of haemolytic jaundice was attributable to alloimmunisation and 39% of nonhaemolytic jaundice was attributable to preterm birth. CONCLUSION Haemolytic and nonhaemolytic neonatal jaundice had different risk factor profiles. Interventions to reduce maternal alloimmunisation, preterm birth and maternal obesity may lower the prevalence of neonatal jaundice and the risk of consequent neurological complications.

Abstract
Scoparone (6,7-dimethoxycoumarin) is the representative ingredient of Yinchenhao (Artemisia capillaris Thunb.) which is a famous Chinese medicinal herb and shows favorable efficacy for all kinds of liver disease, specifically for the treatment of Yanghuang syndrome (YHS). The precise molecular mechanism concerning the action of scoparone on YHS is yet to be fully elucidated. The aim of the present study was to determine the mechanism of scoparone and evaluate its efficacy on metabolite levels. The differential expression of metabolites responsible for the pharmacological effects of scoparone was characterized and the protection effect of scoparone against this disease. Using multivariate statistical analysis, 33 biomarkers were identified using precise MS/MS and play an important role in the regulation of key metabolic pathways associated with liver disease. In addition, pathological results also showed consistent changes in the YHS model group and after treatment with scoparone, both the metabolic profile and histopathology resembled that of normal level, which suggesting favorable efficacy over the observed time period. The present work indicated that a metabolomics platform provided a new insight into understanding the mechanisms of action of natural medicines such as scoparone.

Abstract
OBJECTIVE Whether neonatal hyperbilirubinemia and/or phototherapy increase the risk of autism spectrum disorder (ASD) is unclear. We sought to quantify the risk of ASD associated with elevated total serum bilirubin (TSB) levels and with phototherapy. METHODS In a retrospective cohort study of 525 409 infants born at ≥35 weeks' gestation in 15 Kaiser Permanente Northern California (KPNC) hospitals, 1995-2011, we obtained all TSB levels and determined which infants received phototherapy. From the KPNC Autism Registry, we identified patients with ASD diagnosed at a KPNC Autism Center, by a clinical specialist, or by a pediatrician. We calculated Cox proportional hazard ratios (HRs) for time to diagnosis of ASD, adjusting for confounding factors. RESULTS Among infants in the birth cohort, 2% had at least 1 TSB level ≥20 mg/dL, and 8% received phototherapy. The rate of ASD was 13 per 1000 births. Crude analyses revealed an association between TSB ≥20 and ASD (relative risk: 1.4; 95% confidence interval [CI]: 1.1-1.6), and between phototherapy and ASD (relative risk: 1.7; 95% CI: 1.5-1.8). After adjusting for confounders, TSB ≥20 (HR: 1.09; 95% CI: 0.89-1.35) and phototherapy (HR: 1.10; 95% CI: 0.98-1.24) were no longer significantly associated with ASD. Independent risk factors for ASD included maternal and paternal age; maternal and paternal higher education; male sex; birth weight <2500 g or ≥4200 g; and later year of birth. CONCLUSIONS After adjustment for the effects of sociodemographic factors and birth weight, neither hyperbilirubinemia nor phototherapy was an independent risk factor for ASD.

Abstract
OBJECTIVE To determine whether neonatal phototherapy is associated with cancer in the first year after birth. METHODS We analyzed a data set from the California Office of Statewide Health Planning and Development that was created by linking birth certificates, death certificates, and hospital discharge abstracts up to age 1 year. Subjects were 5 144 849 infants born in California hospitals at ≥35 weeks' gestation from 1998 to 2007. We used International Classification of Diseases, Ninth Revision codes to identify phototherapy at <15 days and discharge diagnoses of cancer at 61 to 365 days. We adjusted for potential confounding variables by using traditional and propensity-adjusted logistic regression models. RESULTS Cancer was diagnosed in 58/178 017 infants with diagnosis codes for phototherapy and 1042/4 966 832 infants without such codes (32.6/100 000 vs 21.0/100 000; relative risk 1.6; 95% confidence interval [CI], 1.2-2.0, P = .002). In propensity-adjusted analyses, associations were seen between phototherapy and overall cancer (adjusted odds ratio [aOR] 1.4; 95% CI, 1.1-1.9), myeloid leukemia (aOR 2.6; 95% CI, 1.3-5.0), and kidney cancer (aOR 2.5; 95% CI, 1.2-5.1). The marginal propensity-adjusted absolute risk increase for cancer after phototherapy in the total population was 9.4/100 000 (number needed to harm of 10 638). Because of the higher baseline risk of cancer in infants with Down syndrome, the number needed to harm was 1285. CONCLUSIONS Phototherapy may slightly increase the risk of cancer in infancy, although the absolute risk increase is small. This risk should be considered when making phototherapy treatment decisions, especially for infants with bilirubin levels below current treatment guidelines.

A decision-making tool for exchange transfusions in infants with severe hyperbilirubinemia in resource-limited settings. J Perinatol 2016; 36:338-41. [PMID: 26938921 DOI: 10.1038/jp.2016.25] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2015] [Revised: 01/18/2016] [Accepted: 01/26/2016] [Indexed: 11/08/2022]
Abstract
Late presentation and ineffective phototherapy account for excessive rates of avoidable exchange transfusions (ETs) in many low- and middle-income countries. Several system-based constraints sometimes limit the ability to provide timely ETs for all infants at risk of kernicterus, thus necessitating a treatment triage to optimize available resources. This article proposes a practical priority-setting model for term and near-term infants requiring ET after the first 48 h of life. The proposed model combines plasma/serum bilirubin estimation, clinical signs of acute bilirubin encephalopathy and neurotoxicity risk factors for predicting the risk of kernicterus based on available evidence in the literature.
