Background: The objective assessment of the severity of neonatal jaundice is Total Serum Bilirubin (TSB) determination, which requires multiple blood sampling. This has inherent problems, including risks of anaemia and infection. Transcutaneous Bilirubinometry (TcB) is a reliable, non-invasive alternative, however there is paucity of data on its performance in black preterm neonates.Objectives: To evaluate the correlation between transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) among Nigerian preterm neonates, and to determine the parameters affecting the relationship.Method: Jaundiced preterm neonates delivered between 28 and 36 weeks of gestation admitted at the Irrua Specialist Teaching Hospital (ISTH), Nigeria were recruited . The TSB levels were determined by spectrophotometry while the corresponding TcB levels were obtained using Jaundice Meter (JM-103). The neonates were stratified into gestational age and birth weight groups.Results: A total of 189 paired TcB and TSB levels were obtained from 60 neonates. The Mean (sd) TcB level of 11.4 (3.1) mg/dl was significantly higher than the mean TSB level of 10.2 (2.8)mg/dl (p= 0.028). The overall correlation coefficient between TcB and TSB was 0.98 and it was not significantly affected by the gestational age, birth weight and bilirubin levels.Conc lusion: Transcutneous bilirubin strongly correlates with total serum bilirubin levels among Nigerian preterm neonates, irrespective of gestational age, birth weight and the degree of jaundice.Keywords: hyperbiliruinaemia, jaundice meter, Nigerian, preterm, neonates, transcutaneous bilirubinometry

Abstract Transcutaneous measurement of bilirubin is being used for neonatal jaundice. Its utility during phototherapy in preterm babies is not established. Objective of our study was to assess the efficacy of transcutaneous bilirubin (TcB) measurement in comparison to total serum bilirubin in preterm newborns at admission and during phototherapy at covered skin area (glabella). It was a prospective observational study and conducted at neonatal intensive care unit of a tertiary care hospital from January 2017 to January 2019. One hundred eligible preterm neonates were enrolled. Babies who were very sick, with poor peripheral circulation, edematous, having conjugated hyperbilirubinemia, with major congenital malformations, already received phototherapy or exchange transfusion were excluded. Paired total serum bilirubin and transcutaneous bilirubin were measured at admission, at 6 hours and 24 hours during phototherapy. TcB was measured from area (glabella) covered by eye protector during phototherapy. Sample for TsB was taken within 10 minutes of TcB measurement. The mean difference between TsB and TcB values at admission, 6 hours and 24 hours of phototherapy were -0.005 (0.353), --0.350 (0.611), and -0.592 (0.353) respectively. At admission or before starting of phototherapy the difference (TsB-TcB) was statistically not significant (p=.125), while the difference in these values were statistically significant at 6 hours and 24 hours of phototherapy. Conclusion: TcB measurements from covered skin area in jaundiced preterm infants during phototherapy were not correlated with TsB and cannot be used as an alternate of serum bilirubin levels.

Transcutaneous Bilirubinometry

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.

Background: Hyperbilirubinemia is common in neonates, with higher prevalence among preterm neonates, which can lead to severe hyperbilirubinemia. Assessment of total serum bilirubin (TSB) and use of a transcutaneous bilirubinometer (TcB) are existing methods to identify and predict hyperbilirubinemia. This study aimed to determine TcB cut-off values during the first day for preterm neonates to predict hyperbilirubinemia at 48 and 72 hours. Methods: A total of 90 neonates born ≤35 weeks were included in the study. They were divided into two groups (Group I: 1000-1500 grams; Group II: 1501-2000 grams). The bilirubin level was measured on the sternum using TcB at the ages of 12, 24, and 72 h. TSB measurements were taken on the third day or if TcB level reached ± 1.24 mg/dL phototherapy threshold and if TcB showed abnormal results (Group I: 5.76-8.24 mg/dL; Group II: 8.76-11.24 mg/dL). Hyperbilirubinemia was defined as TSB ≥7 mg/dL for group I and >10 mg/dL for group II. Results: In total, 38 group I neonates and 48 group II neonates were observed. Almost half of neonates in group I (44.7%) were suffering from hyperbilirubinemia at the age of 48 hours, with 45.8% of group II at the age of 72 hours. To predict hyperbilirubinemia at the age of 48 hours, the best 24-hour-age TcB cut-off values were calculated to be 4.5 mg/dL for group I and 5.8 mg/dL for group II. To predict hyperbilirubinemia at the age of 72 hours, we determined 24-hour-age TcB value of 5.15 mg/dL for group II. Conclusion: TcB values in the early days of life can be used as hyperbilirubinemia predictors on the following days for preterm neonates. Close monitoring should be managed for those with TcB values higher than the calculated cut-off values.

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.

Transcutaneous Bilirubinometry

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
