Objective: To evaluate the utility of a Transcutaneous Bilirubin nomogram in high risk neonates and to evaluate the validity of Transcutaneous Bilirubin and Total serum bilirubin in both low and high-risk neonates. Study Design: Cross-sectional study. Place and Duration of Study: Postnatal Ward, Aga Khan University Hospital, Karachi, from May to Oct 2019. Methodology: The participants will include all neonates born and admitted in the well baby nursery withjaundice. All neonates with gestational age of <35 weeks, requiring admission in Neonatal intensive care unit, and neonates with conjugated hyperbilirubinemia will be excluded. We will stratify our neonates into high and low risk population based on predefined criteria. Eighty five neonates in low risk group and 122 neonates in high risk group will be included. Results: We aim to assess the effectiveness of Transcutaneous Bilirubin nomogram in high risk neonates asan effective and non-invasive tool in the management of neonatal jaundice in high risk neonates. We will alsoassess the sensitivity and specificity of Transcutaneous Bilirubin and Total serum bilirubin measurementsand the analysis would be performed separately for high risk and low risk neonates to evaluate the validity ofTranscutaneous Bilirubin independently in both groups. Conclusion: We hope to establish a validated phototherapy guideline based on the Transcutaneous Bilirubinnomogram, as a cost effective and noninvasive tool in the management of neonatal jaundice in both high and low risk groups in Pakistan.

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.

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.

Background Neonatal hyperbilirubinemia is commonly found in newborns. Assessment of the risk of hyperbilirubinemia and information on the average time of the occurrence of hyperbilirubinemia are important to prevent the development of severe hyperbilirubinemia.Objective To find out the incidence of and the time of the development of hyperbilirubinemia in healthy-term newborns.Method A cohort prospective study was done on healthy-term newborns born at Hasan Sadikin Hospital between November and December 2009. Subjects were divided into 4 groups of risk at discharged, based on Bhutani nonnogram. A serial bilirubin level measurement were perfonned within 6 days.Resu l ts One of 14 newborns at low risk group developed hyperbilirubinemia but did not need phototherapy. Six of 14 newborns at intermediate-low risk group developed hyperbilirubinemia, 2 of them needed phototherapy with total serum bilirubin level of 14.7 mg/dL at 57 hours and 19.8 mg/dL at111 hours. Nine of 15 newborns of intennediate-high risk group developed hyperbilirubinemia, 1 of them needed phototherapy with total serum bilirubin level of 16.6 mg/dL at 76 hours. There was no newborn cathegorized as high risk group in this study. The median time the occurrence of hyperbilirubinemia in intennediate-low and intennediate-high risk group was 140 hours and 82 hours, respectively. There was no significant difference in survival curve between intennediate-high and intennediate-low risk groups (95% CI 108.1 to 1 2 5.4).Conclusion The incidence of hyperbilirubinemia was not different between intennediate-low and intermediate-high risk babies.

Objective. To evaluate the effectiveness of transcutaneous bilirubin (TcB) measurement in predicting risk for neonatal hyperbilirubinemia in outpatients. Design. Subjects were infants ≤8 days old seen in an outpatient clinic. Infants discharged with high-risk (HR) or high-intermediate risk (HIR) total serum bilirubin (TSB) values and jaundiced infants were recruited. TSB and TcB (BiliChek) levels were plotted on an hour-specific nomogram to determine risk for hyperbilirubinemia. Results. A total of 79 infants provided 87 sets of TcB and TsB values. Mean bias and standard deviation between TcB and TsB was 1.5 ± 2.1 mg/dL for outpatients, compared with 2.7 ± 1.3 mg/dL for inpatients. The sensitivity and specificity of HR or HIR TcB for predicting an HR or HIR TSB were 87% and 58%, respectively. Of 9 infants readmitted for phototherapy, 1 had a low-risk TcB and high-risk TSB. Conclusions. TcB screening in the outpatient environment may not be safe and efficient.

SARS-CoV-2 is a worldwide challenge for the medical sector. Healthcare workers (HCW) are a cohort vulnerable to SARS-CoV-2 infection due to frequent and close contact with COVID-19 patients. However, they are also well trained and equipped with protective gear. The SARS-CoV-2 IgG antibody status was assessed at three different time points in 450 HCW of the University Hospital Essen in Germany. HCW were stratified according to contact frequencies with COVID-19 patients in (I) a high-risk group with daily contacts with known COVID-19 patients (n = 338), (II) an intermediate-risk group with daily contacts with non-COVID-19 patients (n = 78), and (III) a low-risk group without patient contacts (n = 34). The overall seroprevalence increased from 2.2% in March–May to 4.0% in June–July to 5.1% in October–December. The SARS-CoV-2 IgG detection rate was not significantly different between the high-risk group (1.8%; 3.8%; 5.5%), the intermediate-risk group (5.1%; 6.3%; 6.1%), and the low-risk group (0%, 0%, 0%). The overall SARS-CoV-2 seroprevalence remained low in HCW in western Germany one year after the outbreak of COVID-19 in Germany, and hygiene standards seemed to be effective in preventing patient-to-staff virus transmission.

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.

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.
