Jaundice is one of the most common diseases that have a significant impact in the first few days of newborn life. Detection and regular monitoring of bilirubin, which is responsible for Jaundice, is an essential phase during the hyperbilirubinemia. In the literature, various clinical assessment methods of Jaundice are available. It motivates us to present a review of these clinical assessment methods in practice, along with their advantages and limitations. In this paper, we have discussed three widely used methods, such as visual assessment, total serum bilirubin and transcutaneous bilirubinometer. From the comparative analysis of these methods, it is concluded that the visual assessment is very subjective in nature, whereas, the total serum bilirubin method is still a gold standard method. The detailed analysis of the methods depicts that the correlation between this two total serum bilirubin and transcutaneous bilirubinometer has enormous potential for improvement resulting in the enhancement in precision and accuracy of bilirubin measurement.

INTRODUCTION: Hyperbilirubinemia is a common problem in the neonates. It can progress to develop kernicterus unless intervention is initiated. Severity of jaundice and decision for management are usually based on total serum bilirubin (TsB) estimation which technique and results closely correlates with total serum bilirubin levels. OBJECTIVES: To compare the accuracy of visual assessment of jaundice by single trained observer based on Kramer's index with total serum bilirubin levels in healthy term neonates. To compare accuracy of non invasive bilirubin assessment with serum bilirubin levels, to compare trans-cutaneous bilirubin assessment on different sites (forehead and sternum) and to develop a cutoff point oftrans-cutaneous bilirubin level for serum bilirubin assessment. METHODS: This prospective study was conducted in the Neonatal unit of the department of Paediatrics at Kasturba Hospital ,Manipal. Study period was from October 2007 to June 2008. Clinical assessment of jaundice was done in healthy term neonates by observer (Trained Paediatric Post Graduate Resident) based on Kramer's index. Transcutaneous bilirubin assessment was done on the forhead and sternum of each baby using JM-103 Minolta. Air shields bilirubino meter. Serum bilirubin level was measured within 30 minutes of the clinical assessment for each baby. RESULTS: This study included 187 healthy term neonates. The mean birth weight was 2856.83gm ± 493.89gm and mean gestation was 38.25+ 1.030 SD. Clinical assessment and Transcutaneous bilirubin(TcB) significantly correlated with total serum bilirubin (TsB), with correlation co-efficient of 0.757 and 0.801 respectively (p 0.0001). Transcutaneous bilirubin assessment over forehead showed a tendency to under estimate total serum bilirubin, with mean difference of-0.31 mg/dl, SD 1.75 mg/dl with 95% confidence interval ofthe mean -0.60 and -0.02 mg/dl (p value 0.05).Transcutaneous bilirubin assessments between 10 mg/dl to 15 mg/dl correlated accurately with total serum bilirubin levels avoiding blood sampling. CONCLUSION: Trained observer clinical assessment of jaundice can be used for screening neonatal jaundice. Non invasive transcutaneous bilirubin assessment has demonstrated significant accuracy with serum bilirubin level estimates between 48 hours to 7 days on two different sites forehead and sternum.

Background: Crigler–Najjar syndrome type I (CN-1) and type II (CN-2) are rare hereditary unconjugated hyperbilirubinemia disorders. However, there have been no reports regarding the co-existence of CN-1 and CN-2 in one family. We experienced a case of an Iranian family that included members with either CN-1 or CN-2. Genetic analysis revealed a mutation in the bilirubin UDP-glucuronosyltransferase (UGT1A1) gene that resulted in residual enzymatic activity.Case report: The female proband developed severe hyperbilirubinemia [total serum bilirubin concentration (TB) = 34.8 mg/dL] with bilirubin encephalopathy (kernicterus) and died after liver transplantation. Her family history included a cousin with kernicterus (TB = 30.0 mg/dL) diagnosed as CN-1. Her great grandfather (TB unknown) and uncle (TB = 23.0 mg/dL) developed jaundice, but without any treatment, they remained healthy as CN-2. Results: The affected cousin was homozygous for a novel frameshift mutation (c.381insGG, p.C127WfsX23). The affected uncle was compound heterozygous for p.C127WfsX23 and p.V225G linked with A(TA)7TAA. p.V225G-UGT1A1 reduced glucuronidation activity to 60% of wild-type. Thus, linkage of A(TA)7TAA and p.V225G might reduce UGT1A1 activity to 18%–36 % of the wild-type. Conclusion: Genetic and in vitro expression analyses are useful for accurate genetic counseling for a family with a history of both CN-1 and CN-2. Abbreviations: CN-1: Crigler–Najjar syndrome type I; CN-2: Crigler–Najjar syndrome type II; GS: Gilbert syndrome; UGT1A1: bilirubin UDP-glucuronosyltransferase; WT: Wild type; TB: total serum bilirubin.

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.

A 36-week gestation newborn was admitted to the neonatal intensive care unit for treatment of primary pulmonary hypertension and possible sepsis. The infant developed hyperbilirubinemia on day 4 of life and peaked on day 5 at a total serum bilirubin of 19 mg/dL. Phototherapy was started on day 4 and continued for 5 days. On day 8 of life, ibuprofen was started for fever; a concurrent total serum bilirubin was 15.7 mg/dL. The subsequent hospital course was uneventful, and discharge occurred on day 22 of life. Because the patient failed a hearing screen at discharge, he was referred for a diagnostic audiology workup. He subsequently failed formal audiometric testing on two occasions one week apart, and was given a diagnosis of auditory dys-synchrony and/or auditory neuropathy, consistent with kernicterus. At 5½ months of age, he was reported to be hypotonic and to have frequent arching movements. Since the total serum bilirubin did not exceed 19 mg/dL, concern was raised that ibuprofen may have caused displacement of bilirubin from its albumin binding site, resulting in kernicterus due to excessive unbound bilirubin concentrations. Ibuprofen should be administered with caution in preterm infants at risk for kernicterus.

Background Although phototherapy has been used in clinical practice for 40 years, there is still much debate on how to provide the most efficacious phototherapy. Phototherapy with white reflecting curtains may increase the average spectral irradiance provided, as well as decrease serum bilirubin concentrations at a faster rate in neonates with jaundice.Objective To determine if adding low cost, white, reflecting curtains to a standard phototherapy unit can increase the effectiveness of phototherapy for neonatal jaundice.Methods A randomized, controlled, open trial was conducted at H. Adam Malik and Pirngadi Hospitals, Medan, from May to December 2009. The criteria for inclusion in the study were full term newborns with neonatal jaundice presenting in their first week of life. Single phototherapy with white curtains hanging from the sides of the phototherapy unit (study group, n=30) was compared to single phototherapy without curtains (control group, n=30). The primary outcomes measured were the mean difference in total serum bilirubin levels and average spectral irradiation levels measured at baseline, and after 12 hours and 24 hours of phototherapy.Results The sum of average spectral irradiance in the curtained phototherapy unit was significantly higher than that of the standard phototherapy unit without curtains (P < 0.05). The decrease of total serum bilirubin levels after 12 and 24 hours of phototherapy was significantly greater in the study group (3.71 and 9.7 mg/dl, respectively) than in the control group (0.1 and 3.8 mg/dl, respectively), both P <0.05.Conclusion White, reflecting curtains in phototherapy units was significantly more effective than phototherapy without curtains for treatment of neonatal jaundice.
