Background The gold standard for diagnosis of neonatal jaundice is total serum bilirubin (TSB) measurement. This method, however, is invasive, painful, and costly in terms of workload, time, and money. Moreover, repeated blood sampling may lead to significant blood loss, which is of particular concern in preterm infants. To overcome these drawbacks, non-invasive methods of bilirubin measurement have been proposed. Transcutaneous bilirubinometry (TcB) determines the yellowness of the subcutaneous tissue of a newborn infant by measuring the difference between optical densities for light in the blue and green wavelength regions.Objective To evaluate the accuracy of transcutaneous bilirubinometry for estimating TSB levels in neonatal jaundice.Methods Subjects were infants aged < 28 days with jaundice who had never been treated with phototherapy or exchange transfusion. The study was done from February to July 2016 in Mohammad Hoesin Hospital. Subjects underwent transcutaneous bilirubin (TcB) and TSB assays, with a maximum interval of 15 minutes between tests.Results One hundred fifty patients were included in this study. The TcB values > 5 mg/dL were correlated to TSB > 5 mg/dL, with 100% sensitivity and 83.3% specificity. This cut-off point was obtained from a receiver-operator characteristic (ROC) curve with AUC 99.3% (95%CI 97.9 to 100%; P< 0.001).The correlation coefficients (r) for TSB and TcB measurements on the forehead were 0.897 (P<0.001).Conclusion Transcutaneous bilirubinometry can be used to accurately estimate TSB levels in neonatal jaundice, and may be useful in clinical practice as a non-invasive method to reduce blood sampling.

Introduction: Jaundice is an important problem during neonatal period. When total serum bilirubin (TSB) level exceeds a critical limit, it crosses the blood brain barrier and results into bilirubin encephalopathy. The main aim of therapy for neonatal hyperbilirubinemia is prevention of bilirubin encephalopathy by phototherapy and/or exchange transfusion. The aims of this study were to evaluate the efficacy of exchange transfusion (ET) and observe the adverse events during and following three days of ET in neonates with hyperbilirubinemia. Materials and Method: Hospital based cross-sectional descriptive study. All neonates admitted to neonatal intensive care unit and /or paediatric wards of a tertiary- care centre between September 2010 to March 2012, requiring ET were enrolled. Results: A total of 139 ETs were performed in 120 neonates. The common causes were ABO incompatibility (30.8%), prematurity (30.8%), idiopathic (27.5%), Rh isoimmunization (6.7%) and cephalhematoma (4.2%). Mean pre- ET total serum bilirubin (TSB) was 24.2 mg% dL. There was 58% reduction in TSB in post ET and 31% net reduction in 6 hr post ET. Term and preterm neonates showed equal percentage of TSB reduction. Respiratory distress (10.8%) and bradycardia (6.7%) were the common adverse events during, and hypocalcemia (98.3%) and thrombocytopenia (34.2%) in 3 days following ET. The sick neonates had significantly higher incidence of thrombocytopenia (p= 0.031), respiratory distress (p=0.009), apnea (p<0.001) and cardiorespiratory arrest (p<0.001). Overall mortality was 4.2%, and non-survivors were mostly low birth weight, born outside the present hospital and had higher incidence of adverse events. Conclusion: Exchange transfusion is an effective intervention in reducing the serum bilirubin level. However, these neonates require monitoring of ionised calcium and thrombocytopenia. Sick neonates had higher incidence of adverse events than healthy and close clinical monitoring is needed to improve the outcome.

The accuracy of transcutaneous bilirubin meters has been assessed in newborns from various ethnic backgrounds. However, there are limited data on Greek newborns. Our study examined the accuracy of transcutaneous bilirubin measurements in clinically jaundiced healthy-term Greek newborns, using total serum bilirubin as the reference standard, in order to re-evaluate our local guidelines about neonatal jaundice. Clinically jaundiced newborns requiring total serum bilirubin level estimation were recruited prospectively. 368 pairs of total serum bilirubin/transcutaneous bilirubin measurements were taken in 222 newborns, using a direct spectrophotometric device and the BiliCheck device, respectively. The level of agreement between the obtained transcutaneous bilirubin and total serum bilirubin values was assessed. Our data were analysed using the Stata/SE 12.0 (StataCorp LP, USA) statistical programme. The mean (± SD) TSB was 225.4 ± 25.4 μmol/l and the mean (± SD) TcB was 237.9 ± 21.0 μmol/l. The correlation between the values was poor (Pearson’s correlation coefficient 0.439; Lin’s concordance coefficient 0.377 [95% CI 0.301 to 0.453]; P<0.001). The Bland-Altman analysis demonstrated that transcutaneous bilirubin measurements tended to overestimate the total serum bilirubin value (mean difference 12.5 ± 24.9 μmol/l), with wide 95% limits of agreement (–36.2 μmol/l to 61.3 μmol/l). Transcutaneous bilirubin values did not correlate well with total serum bilirubin values, being often imprecise in predicting the actual total serum bilirubin levels. This permits us to continue estimating total serum bilirubin in clinically jaundiced newborns according to our local guidelines, in order to safely decide the appropriate care plan.

Background: Hyperbilirubinemia is a common problem in newborn. Most of the cases are benign but severe hyperbilirubinemia can lead to kernicterus and brain damage which is preventable. The gold standard to asses neonatal hyperbilirubinaemia is serum bilirubin measurement. Unfortunately, this procedure is invasive, painful and time consuming. As the consequence of missing severe hyperbilirubinemia is serious, there is a constant search to find out a safe method to detect jaundice. Transcutaneous bilirubinometry offers objective method of assessing degree of jaundice reducing subjectivity of clinical assessment.Objective: To evaluate the relationship between transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) and assess whether transcutaneous bilirubinometry can be used as a valid screening method for detecting jaundice in term and late preterm babies.Method: A prospective cross-sectional study was performed in well baby nursery of United Hospital Limited, Dhaka from January 2013 to December 2013. Healthy term and late pre term newborn of ?35 wk gestation with clinical evidence of jaundice were included in the study. Total serum bilirubin was measured by Dichlorophenyl Diazonin method and transcutaneous bilirubinometer (JM-103) was used to measure transcutaneous bilirubin (TcB) level.Result: A total of 116 paired samples were analyzed and found strong correlation between TcB and TSB (correlation coefficient 0.8, mean difference 0.83, SD± 1.96 and 95% CI 0.6 to 1.06). Post natal age has significant association with TcB (p value 0.01) and TSB (p value 0.031). Requirement of phototherapy in both group were also significant (p value <0.001). TcB value of 11 mg/dl was chosen as cut off point corresponding TSB level 13 mg/dl with sensitivity 90% and specificity 71%. Above this level indicate need for blood sampling to take appropriate therapeutic measure.Conclusion: Transcutaneous billirubinometry is a non-invasive and valid screening tool for assessing jaundice in newborn.Bangladesh J Child Health 2015; VOL 39 (3) :116-122

Background: Timely detection and treatment of pathological hyperbilirubinemia in newbornscan prevent acute bilirubin encephalopathy and its consequences. We aimed to identifyitsoccurrence, presentationtime, phototherapyduration, need for exchange transfusion,and outcome. Methods: In this cross-sectional study, we enrolled all the babies admitted for pathological neonatal hyperbilirubinemia in the university hospital ofBPKIHSin a one-yearduration. Babies with life-threatening congenital malformations or conjugated bilirubin >20% of total serum bilirubin or >2 mg/dl were excluded. Obstetric profile of mothers, clinical and laboratory parameters of babies, onset time of pathological jaundice, duration of phototherapy, need for exchange transfusion or intravenous immunoglobulin were recorded. Neonatal outcome was classified as good and poor and its association with potential predictors analyzed.  Results: One-hundred and fifty babiesdeveloped neonatal jaundice requiring treatment. The most common causes includedABO and Rh setting. No cause was found in 26 (18%) babies. One-hundred and eight babies (72%) were only managed withphototherapy whereas 42 (28%) required both phototherapy and double volume exchange therapy. The majority (84.5%) had good outcome without any residual neurological deficit at discharge.Babies with total serum bilirubin >20 mg/dl at presentation, duration of phototherapy >44.8 h, ABO setting, hemolysis, and out born statussignificantly developed poor outcome (p < 0.05). Conclusion: About 15% of the babies with hyperbilirubinemia had acute bilirubin encephalopathy at discharge suggestive of poor outcome. Babies with high bilirubin at presentation, longer duration of phototherapy, ABO settings, hemolysis, and out born statusdeveloped poor outcome.

Background: Neonatal hyperbilirubinemia is a common clinical problem encountered during the neonatal period, especially in the first week of life. It is a multifactorial disorder with many symptoms. Most of these cases are benign but it is important to identify those babies at risk of acute bilirubin encephalopathy and kernicteurs or chronic encephalopathy. Jaundice may also be a sign of a serious underlying illness. Objectives: Describe and examine the relationship between clinical characteristics with laboratory tests of indirect hyperbilirubinemia in neonatal. Methods: A cross-sectional descriptive. A convenient sample includes 124 patients under 28 days old had jaundice and were treated at Neonatal room, Hospital of Hue University of Medicine and Pharmacy from 05/2015 to 06/2016. Results: The proportion of male/female is 1.3/1. 66.9% is in term infants. 73.4% onset of jaundice in 24 - 72 hours of age. 67.7% had jaundice all the body before were taken to neonatal room. 47.6% cases were caused by neonatal infection. 93.5% cases had total serum bilirubin < 340 µmol/L. It has a weak positive correlation between the degree of clinical jaundice with level of total serum bilirubin. 31/124 cases suspected ABO incompatibility but Coombs test were negative, however they had high rate of anemia than the others is 13.2 times (p<0.01). Conclusions: Indirect hyperbilirubinemia in neonatal is usually detected when the baby had jaundice to hands and feet. Therefore precautionary measure should be adopted by both parents and clinicians to diagnose and treat the disease properly. Key words: jaundice, hyperbilirubinemia, neonatal

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.
