Heliotherapy for neonates with severe-to-hazardous hyperbilirubinemia: a randomized controlled, non-inferiority trial

Filtered-sunlight phototherapy (FSPT) that blocks ultraviolet light and reduces infrared radiation is safe and non-inferior to intensive electric phototherapy (IEPT) for treating mild-to-severe neonatal hyperbilirubinemia. In this randomized non-inferiority trial, the safety, efficacy, exchange transfusion (ET), and mortality rates of FSPT versus IEPT among Nigerian neonates with severe-to-hazardous hyperbilirubinemia were investigated. Safety was defined as the absence of hyperthermia, hypothermia, dehydration, or sunburn; efficacy by the proportion of assessable treatment days during which total serum or plasma bilirubin (TSB) increased by < 0.2 mg/dL/hr for newborns aged ≤ 72 h-old or decreased for newborns > 72 h-old. A treatment day was deemed assessable if a neonate received phototherapy for ≥ 4 h, and non-inferiority was inferred for differences within a 10% margin. We enrolled 192 newborns (admission TSB ≤ 62 mg/dL), assigned to FSPT (n = 98) or IEPT (n = 94). FSPT was effective on 94.2% of the assessable treatment days compared with 97.1% for IEPT. The mean difference in efficacy between FSPT and IEPT was -2.9%, 95% CI: -7.6, 1.9). 2.6% of newborns who received FSPT developed controlled hyperthermia, and no baby met the criteria for withdrawal for safety reasons. Overall, 50.6% (39/77) of newborns who received FSPT and 53.7% (51/95) of newborns who received IEPT had ET (p = 0.89) and 7 in each group (9.1% vs 7.4%; p = 0.86) died. In conclusion, FSPT is safe and non-inferior to IEPT for treating neonates with severe-to-hazardous hyperbilirubinemia, it is not associated with significantly higher rates of ET and mortality and should be considered where practicable when IEPT cannot be assured.

Exchange Transfusion Trends and Risk Factors for Extreme Neonatal Hyperbilirubinemia over 10 Years in Shiraz, Iran.

Exchange transfusion (ET) is an effective treatment for acute bilirubin encephalopathy and extreme neonatal hyperbilirubinemia (ENH). It can reduce mortality and morbidity. This study aimed to investigate the trends and risk factors of ENH requiring ET in hospitalized neonates in Iran. A retrospective analysis of medical records of neonates who underwent ET due to ENH was conducted from 2011 to 2021, in Shiraz, Iran. Clinical records were used to gather demographic and laboratory data. The quantitative data were expressed as mean±SD, and qualitative data was presented as frequency and percentage. P<0.05 was considered statistically significant. During the study, 377 ETs were performed for 329 patients. The annual rate of ET decreased by 71.2% during the study period. The most common risk factor of ENH was glucose-6-phosphate dehydrogenase (G6PD) deficiency (35%), followed by prematurity (13.06%), ABO hemolytic disease (7.6%), sepsis (6.4%), Rh hemolytic disease (6.08%), and minor blood group incompatibility (3.34%). In 28.52% of the cases, the cause of ENH was not identified. 17 (5.1%) neonates had acute bilirubin encephalopathy, of whom 6 (35.29%) had G6PD deficiency, 6 (35.29%) had ABO incompatibility, and 2 (11.76%) had Rh incompatibility. Although the rate of ET occurrence has decreased, it seems necessary to consider different risk factors and appropriate guidelines for early identification and management of neonates at risk of ENH should be developed. The findings of the study highlighted the important risk factors of ENH in southern Iran, allowing for the development of appropriate prevention strategies.

Transcutaneous bilirubinometry for detecting jaundice in term or late preterm neonates.

The American Academy of Pediatrics and the Canadian Paediatric Society both advise that all newborns should undergo bilirubin screening before leaving the hospital, and this has become the standard practice in both countries. However, the US Preventive Task Force has found no strong evidence to suggest that this practice of universal screening for bilirubin reduces the occurrence of significant outcomes such as bilirubin-induced neurologic dysfunction or kernicterus. To evaluate the effectiveness of transcutaneous screening compared to visual inspection for hyperbilirubinemia to prevent the readmission of newborns (infants greater than 35 weeks' gestation) for phototherapy. We searched CENTRAL, MEDLINE, Embase, CINAHL, ClinicalTrials.gov, ICTRP, and ISRCTN in June 2023. We also searched conference proceedings, and the reference lists of included studies. We included randomized controlled trials (RCTs), quasi-randomized, cluster-randomized, or prospective cohort studies with control arm that evaluated the use of transcutaneous bilirubin (TcB) screening for hyperbilirubinemia in newborns before hospital discharge. We used standard methodologic procedures expected by Cochrane. We evaluated treatment effects using a fixed-effect model with risk ratio (RR) and 95% confidence intervals (CI) for categorical data and mean, standard deviation (SD), and mean difference (MD) for continuous data. We used the GRADE approach to evaluate the certainty of evidence. We identified one RCT that met our inclusion criteria. The study included 1858 African newborns at 35 weeks' gestation or greater who were receiving routine care at a well-baby nursery, and were randomly recruited prior to discharge to undergo TcB screening. The study had good methodologic quality. TcB screening versus visual assessment of hyperbilirubinemia in newborns: - probably reduces readmission to the hospital for hyperbilirubinemia (RR 0.25, 95% CI 0.14 to 0.46; P < 0.0001; moderate-certainty evidence); - may have little or no effect on the rate of exchange transfusion (RR 0.20, 95% CI 0.01 to 14.16; low-certainty evidence); - probably increases the number of newborns who require phototherapy prior to discharge (RR 2.67, 95% CI 1.56 to 4.55; moderate-certainty evidence). - may have little or no effect on the rate of acute bilirubin encephalopathy (RR 0.33, 95% CI 0.01 to 8.18; low-certainty evidence). The study did not evaluate or report cost of care. Moderate-certainty evidence suggests that TcB screening probably reduces hospital readmission for hyperbilirubinemia compared to visual inspection. Low-certainty evidence also suggests that TcB screening may have little or no effect on the rate of exchange transfusion compared to visual inspection. However, moderate-certainty evidence suggests that TcB screening probably increases the number of newborns that require phototherapy before discharge compared to visual inspection. Low-certainty evidence suggests that TcB screening may have little or no effect on the rate of acute bilirubin encephalopathy compared to visual inspection. Given that we have only identified one RCT, further studies are necessary to determine whether TcB screening can help to reduce readmission and complications related to neonatal hyperbilirubinemia. In settings with limited newborn follow-up after hospital discharge, identifying newborns at risk of severe hyperbilirubinemia before hospital discharge will be important to plan targeted follow-up of these infants.

Trends and outcomes of hospitalized patients with priapism in Germany: results from the GRAND study.

We aimed to provide evidence on the trends and in-hospital outcomes of patients with low- and high-flow priapism through the largest study in the field. We used the GeRmAn Nationwide inpatient Data (GRAND), provided by the Research Data Center of the Federal Bureau of Statistics (2008-2021), and performed multiple patient-level analyses. We included 6,588 men with low-flow and 729 with high-flow priapism. Among patients with low-flow priapism, 156 (2.4%) suffered from sickle cell disease, and 1,477 (22.4%) patients required shunt surgery. Of them, only 37 (2.5%) received a concomitant penile prosthesis implantation (30 inflatable and 7 semi-rigid prosthesis). In Germany, the total number of patients with low-flow priapism requiring hospital stay has steadily increased, while the number of patients with high-flow priapism requiring hospital stay has decreased in the last years. Among patients with high-flow priapism, 136 (18.7%) required selective artery embolization. In men with low-flow priapism, sickle cell disease was associated with high rates of exchange transfusion (OR: 21, 95% CI: 14-31, p < 0.001). The length of hospital stay (p = 0.06) and the intensive care unit admissions (p = 0.9) did not differ between patients with low-flow priapism due to sickle cell disease versus other causes of low-flow priapism. Accordingly, in men with high-flow priapism, embolization was not associated with worse outcomes in terms of length of hospital stay (p > 0.9), transfusion (p = 0.8), and intensive care unit admission (p = 0.5). Low-flow priapism is an absolute emergency that requires shunt surgery in more than one-fifth of all patients requiring hospital stay. On the contrary, high-flow priapism is still managed, in most cases, conservatively.

Three or four doses of intravenous immunoglobulin G treatment for isoimmune hemolytic disease: A case series and literature review.

Neonates affected by isoimmune hemolytic disease (HDN) are at risk of developing severe hyperbilirubinemia. Studies show that increasing levels of bilirubin impact neonatal neurodevelopment. To avoid complications associated with exchange transfusion, intravenous immunoglobulin G (IVIG) is used to treat hyperbilirubinemia. We included all infants who received more than two doses of IVIG treatment for isoimmune hemolytic disease. We analyzed the incidence of side effects associated with IVIG treatment and the rate of exchange transfusion. A retrospective chart review performed between October 2011-October 2022 at East Carolina University Health identified neonates who received more than two doses IVIG for HDN. Neonates of postmenstrual age greater than 28 days old, receiving less than three doses of IVIG or received IVIG for other indications were excluded. The occurrences of adverse events, demographics and use of other medical therapies were reviewed. Eleven neonates were included in the case series. Most common cause of severe hyperbilirubinemia was attributed to ABO incompatibility. Six patients (54%) received three doses of IVIG, and five patients (45%) received four doses of IVIG with bilirubin levels decreasing below exchange transfusion. No treatment exceeding four doses of IVIG was reported, nor adverse events during treatment. In this cohort of neonates with HDN, bilirubin levels decreased after treatment with multiple doses of IVIG. Future research on recommendations of optimal total number doses of IVIG to reduce the risk for exchange transfusion.

Effect of delayed cord clamping on red blood cell alloimmunization: a retrospective cohort study

Although delayed cord clamping has well-known benefits for preterm and term neonates, it has been inadequately assessed in alloimmunized neonates. This study aimed to evaluate the benefits and risks of delayed cord clamping in alloimmunized neonates. This was a retrospective comparative pre-post cohort study conducted from 2003 to 2018 in a tertiary care center in France. All living singleton neonates whose mothers were followed up for red blood cell alloimmunization during gestation and confirmed at birth (N=224) were included. Neonates were either exposed to immediate (n=125) or delayed cord clamping (n=99). Our main outcome was the time from birth to first exchange transfusions and/or transfusions. Secondary outcomes were hemoglobin level at birth, rate of exchange transfusion, number of postnatal transfusions, maximum bilirubin level, and number of phototherapy hours. Hemoglobin at birth was significantly higher in case of delayed cord clamping (mean difference, 1.7 g/dL; 95% confidence interval, 0.7-2.8). Among infants treated with exchange transfusion or transfusion, the time to initial treatment was higher in case of delayed cord clamping (median difference, 8 days; rate ratio, 1.51; 95% confidence interval, 1.09-2.10). There were no significant differences in the need for exchange transfusion, the number of transfusions, the maximum total bilirubin level, nor the number of phototherapy hours. In the subgroup analysis of neonates needing intrauterine transfusion during pregnancy (ie, severe alloimmunization), neonates had a lower rate of exchange transfusion in case of delayed cord clamping (odds ratio, 0.36; 95% confidence interval, 0.15-0.82). Our results indicate a benefit of delayed cord clamping in alloimmunization, regardless of pathology severity, without increased risk of jaundice.

The Severity of Direct Antiglobulin Test Negative ABO Hemolytic Disease of Newborn: A Retrospective Analysis at a Tertiary Children’s Hospital

This study aimed to evaluate the severity of ABO hemolytic disease of newborn (ABO-HDN) with negative direct antiglobulin test (DAT), which was identified by elution test. We retrospectively reviewed the clinical records of all neonates admitted with the diagnosis of neonatal hyperbilirubinemia requiring phototherapy or exchange transfusion. Neonates were divided into four groups according to their immunohematology test results. Then their essential laboratory results, magnetic resonance image (MRI), brainstem auditory evoked potential (BAEP) findings, and rate of exchange transfusion were compared between different groups. We found that neonates in ABO-HDN with negative DAT group developed jaundice faster and anaemia more severely than those in the non-HDN group. Although they might get less severe anaemia than neonates in ABO-HDN with positive DAT group and the Rh-HDN group, neonates in ABO HDN with negative DAT group might develop jaundice as quickly as the latter two groups. As to MRI and BAEP findings, there were no significant differences among the four groups. The rate of exchange transfusion in ABO-HDN with negative DAT group was higher than that in the non-HDN group but lower than that in ABO-HDN with positive DAT group, though without statistical significance. It suggested that in the presence of clinical suspicion of ABO-HDN with negative DAT result, the elution test should be added to rule out or confirm the diagnosis to help prevent the morbidity from hyperbilirubinemia.

19 Treatment of Neonatal Hyperbilirubinemia – Ontario Cohort 2014-2018

Abstract Background Serious complications that could result from severe neonatal hyperbilirubinemia include acute and chronic bilirubin encephalopathy. In Ontario, the incidence of severe neonatal hyperbilirubinemia and its associated treatments in term and near-term infants is currently unknown. Although IVIG therapy has been increasingly discussed in the literature, a recent Cochrane review (2018) indicated that there was a lack of evidence for recommending IVIG therapy for routine use. Objectives The purpose of this study was to determine the current incidence of severe neonatal hyperbilirubinemia and its treatments (Intravenous Immunoglobulin (IVIG) therapy, exchange transfusion and phototherapy) most often used in Ontario. Design/Methods A population-based retrospective cohort study of all term and near-term infants (≥ 35 weeks’ gestation) born in Ontario from April 2014 to March 2018 was conducted. National and provincial databases including Better Outcomes Registry Network Ontario (BORN) and Canadian Neonatal Network (CNN) were utilized. Results Data was collected from 533,084 infants born in Ontario over the 4 years. Of the total infants screened, 29,756 (6%) infants were diagnosed with neonatal hyperbilirubinemia. In terms of treatments, 24,646 (83%) infants received phototherapy, 54 (0.18%) infants received an exchange transfusion and 458 (1.5%) infants received IVIG therapy. In Ontario, neonatal hyperbilirubinemia had a statistically significant increase from 2014 to 2018 (P&amp;lt;0.0001). Although phototherapy was used on almost all neonates with hyperbilirubinemia (83%) there was a significant decrease from 2014 to 2018 (from 88% to 80%) (P&amp;lt;0.0001). Of the babies with hyperbilirubinemia in 2014, 71 (1.06%) infants received IVIG therapy and 15 (0.22%) infants received exchange transfusion. Within 4 years, IVIG therapy incidence had a significant increase from 71 (1.06%) infants to 156 (2.04%) infants (P&amp;lt;0.0001), while exchange transfusion remained relatively constant (P=.315). Exchange transfusion rates allows for the prediction that the rate of severe neonatal hyperbilirubinemia is stable in Ontario. Conclusion In conclusion, (severe) hyperbilirubinemia still exists amongst neonates in Ontario, despite the advancements in managing hyperbilirubinemia, indicating the need for better treatments and/or monitoring. There was also a significant rise in the use of IVIG despite the continued debate about its utility. Further research should be conducted nationally to determine the incidence of severe neonatal hyperbilirubinemia and to indicate the usage of IVIG therapy.

Clinical usage of intravenous immunoglobulin in neonates in a tertiary care centre: a retrospective observational study

Background: Intravenous Immunoglobulin (IVIG) is a blood product manufactured from pooled plasma. With increasing availability, an increased usage in neonates is being noted, though its utilisation has not been audited thoroughly. The objectives of this study are to describe the usage pattern and indications of IVIG and its outcome in a state-run tertiary care NICU.Methods: This retrospective observational study was carried out at the inborn unit of Department of Neonatology, Madras Medical College, Chennai on a cohort of neonates who received IVIG over 3.5 years from January 2016 to June 2019. Data was collected from drug register, neonatal case records, exchange transfusion register and death register.Results: Our study cohort had 55 neonates who received IVIG over 3.5 years. Indications for IVIG usage were Rh-alloimmunisation (23), ABO-alloimmunisation (7), prophylaxis of perinatal varicella (20), and other immune thrombocytopenia (5). Among 30 neonates with ABO-/Rh-incompatibility, 11 required exchange transfusion (ET). ET rates have shown a decreasing trend during this period. 2 babies with Rh-immunisation and Hydrops expired. None of the babies given prophylaxis for perinatal varicella manifested the disease. Neonates treated for immune thrombocytopenia were successfully discharged.Conclusions: This study shows the IVIG usage pattern in a tertiary care neonatal unit. In neonates with Hemolytic disease due to Rh-/ABO-alloimmunisation treated with IVIG, a reduction in rates of exchange transfusion has been noted. IVIG is being used increasingly for prophylaxis of perinatal varicella and immune related thrombocytopenia with promising benefits. It is prudent to have SOPs for IVIG administration with standardised issue and transfusion forms for documentation to regulate its judicious use.

Neonatal exchange transfusions at a tertiary care centre in north India: an investigation of historical trends using change-point analysis and statistical process control.

The need for exchange transfusion (ET) as a treatment modality for neonatal hyperbilirubinaemia declined in developed countries with the advent of effective phototherapy. The trends of ET from India are unknown. Our objective was to investigate the trends of ET in India. Retrospective data (January 2006-December 2016) was collected on total outborn neonatal admissions and ET procedures from a centre in north India. A combination of change-point analysis (CPA) and statistical process control (SPC) was used to investigate the trends of ET. During the study period, a total of 39 217 outborn neonates were admitted and 1575 (4%) underwent 1816 ET procedures. The CPA unravels four critical change points (October 2009, May 2011, September 2011 and November 2014) in ET rates. An SPC chart showed a decline in mean ET rate from 89.3 (upper control limit [UCL] 176.9, lower control limit [LCL] 1.7)/1000 neonatal admissions at the start of the study to 7.7 (UCL 34.6, LCL 0)/1000 at the end of the study. The greatest decline in ET rate was witnessed in October 2009, from 89.3 (UCL 176.9, LCL 1.7)/1000 neonatal admissions to 34.8 (UCL 87.1, LCL 0)/1000 neonatal admissions. Our study demonstrated a progressive decline in the number of neonatal ET procedures over 11 y.

Fluid supplementation in term neonates with severe hyperbilirubinemia: a randomized controlled trial study

Background: Severe neonatal jaundice can cause fatality and serious permanent effect, called kernicterus, in which the brain stem nuclei and basal ganglia are damaged. We are encouraged to work on efficacy of fluid supplementation in addition to photo therapy as a measure to reduce bilirubin level more efficiently.Methods: A randomized control trial study was conducted in Department of Paediatric Medicine, Neonatal Unit, R.G. Kar Medical College &amp; Hospital, Kolkata, from April 2011 to March 2012. A total 100 term neonates presenting with severe non-hemolytic hyperbilirubinemia (&gt;18 mg/dl to &lt;25 mg/dl) were enrolled as study population. The study subjects were divided into two equal groups, study group and control group by randomization. The study group was given IV fluid supplementation in addition to photo therapy. Total serum bilirubin (TSB) level assessed periodically and results compared with control group.Results: The study results reveal a statistically significant association between the percent fall in TSB at 12 (Chi2= 7.18, p=0.000) and 24 hours (Chi2=10.69, p=0.000) in the intervention arm compared to the control group.Conclusions: Fluid supplementation along with double surface phototherapy in term neonates presenting with severe hyperbilirubinemia decreases the rate of exchange transfusion and duration of phototherapy.

Evaluation of Risk Factors for Exchange Range Hyperbilirubinemia and Neurotoxicity in Neonates from Hilly Terrain of India.

Background and Aim:Neonatal hyperbilirubinemia continues to be the most common cause of hospital admissions and readmissions in the neonatal population worldwide and this pattern continues despite attempts to identify neonates at risk of pathological hyperbilirubinemia. Therefore, this study aimed to study the risk factors for severe hyperbilirubinemia in neonates.Materials and Methods:An observational prospective study was undertaken for 1 year in neonates with hyperbilirubinemia requiring double volume exchange transfusion in neonatology unit of a tertiary rural health care hospital.Results:Risk factors included ABO incompatibility in 14 (28.5%), Rh incompatibility in 14 (28%). Other risk factors for hyperbilirubinemia were, jaundice in elder sibling, oxytocin use, birth asphyxia, hypothyroidism, ABO along with Rh incompatibility, Glucose-6 phosphate Dehydrogenase deficiency, cephalhematoma, and sepsis in neonates. Ten (20%) neonates were neurologically abnormal with signs of encephalopathy. Significant association of risk factors with neurotoxicity were also found. All neurologically abnormal neonates were small for date and none was appropriate for date (P = 0.05). There were no neurologically abnormal neonates with A+ and O− mothers (P = 0.04).Conclusion:The high rate of exchange transfusion warrants aggressive management of neonatal hyperbilirubinemia by health-care providers by adequate dissemination of information, strict following of hour-based normograms, performing total serum bilirubin assessment in all icteric neonates, and stratification into risk groups thereafter.

Heliotherapy for Neonatal Hyperbilirubinemia in Southwest, Nigeria: A Baseline Pre-Intervention Study.

BackgroundA novel filtered-sunlight phototherapy (FSPT) device has been demonstrated to be safe and efficacious for treating infants with neonatal jaundice in resource-constrained tropical settings. We set out to provide baseline data for evaluating the clinical impact of this device in a referral pediatric hospital.MethodsWe reviewed the medical records of infants admitted for neonatal hyperbilirubinemia in an inner-city Children’s Hospital in Lagos, between January 2012 and December 2014 to determine the pattern, treatment and outcomes during the pre-intervention period. Factors associated with adverse outcomes were identified through multivariable logistic regression.ResultsOf the 5,229 neonatal admissions over the period, a total of 1,153 (22.1%) were admitted for neonatal hyperbilirubinemia. Complete records for 1,118 infants were available for analysis. The incidence of acute bilirubin encephalopathy (ABE) and exchange transfusion (ET) were 17.0% (95% CI: 14.9%–19.3%) and 31.5% (95% CI: 28.8%–34.3%) respectively. A total of 61 (5.5%, 95% CI: 4.3%–6.9%) of the jaundiced infants died. Weight on admission, peak total serum bilirubin (TSB), sepsis and exposure to hemolytic products were predictive of ABE, while age on admission, peak TSB, ABO incompatibility and ABE were predictive of ET. Rhesus incompatibility, asphyxia, exposure to hemolytic substances and ABE were associated with elevated mortality risk, while ET was a protective factor. Lack of routine irradiance monitoring and steady energy supply were frequent challenges for conventional blue-light phototherapy.ConclusionsSevere hyperbilirubinemia is associated with high rates of ABE and ET in this setting, and remains a significant contributor to neonatal admissions and mortality. To be impactful, FSPT, complemented with improved diagnostic facilities, should effectively curtail jaundice-related adverse outcomes in this and comparable settings.

Facility-based constraints to exchange transfusions for neonatal hyperbilirubinemia in resource-limited settings.

Several clinical guidelines for the management of infants with severe neonatal hyperbilirubinemia recommend immediate exchange transfusion (ET) when the risk or presence of acute bilirubin encephalopathy is established in order to prevent chronic bilirubin encephalopathy or kernicterus. However, the literature is sparse concerning the interval between the time the decision for ET is made and the actual initiation of ET, especially in low- and middle-income countries (LMICs) with significant resource constraints but high rates of ET. This paper explores the various stages and potential delays during this interval in complying with the requirement for immediate ET for the affected infants, based on the available evidence from LMICs. The vital role of intensive phototherapy, efficient laboratory and logistical support, and clinical expertise for ET are highlighted. The challenges in securing informed parental consent, especially on religious grounds, and meeting the financial burden of this emergency procedure to facilitate timely ET are examined. Secondary delays arising from post-treatment bilirubin rebound with intensive phototherapy or ET are also discussed. These potential delays can compromise the effectiveness of ET and should provide additional impetus to curtail avoidable ET in LMICs.

Evaluation of a simple intervention to reduce exchange transfusion rates among inborn and outborn neonates in Myanmar, comparing pre- and post-intervention rates

BackgroundIn Myanmar, approximately half of all neonatal hospital admissions are for hyperbilirubinaemia, and tertiary facilities report high rates of Exchange Transfusion (ET). The aim of this study was to evaluate the effectiveness of the pilot program in reducing ET, separately of inborn and outborn neonates.MethodsThe study was conducted in the Neonatal Care Units of four national tertiary hospitals: two exclusively treating inborn neonates, and two solely for outborn neonates. Prior to intervention, no high intensity phototherapy was available in these units. Intervention in late November 2011 comprised, for each hospital, provision of two high intensity LED phototherapy machines, a photo radiometer, and training of personnel. Hospital-specific data were assessed as Relative Risk (RR) ratios comparing ET rates pre- and post-intervention, and individual hospital results were pooled when appropriate.ResultsIn 2011, there were 118 ETs among inborn neonates and 140 ETs among outborn neonates. The ET rate was unchanged at Inborn Hospital A (RR = 1.07; 95 % CI: 0.80–1.43; p = 0.67), and reduced by 69 % at Inborn Hospital B (RR = 0.31; 95 % CI: 0.17–0.57; p < 0.0001). For outborn neonates, the pooled estimate indicated that ET rates reduced by 33 % post-intervention (RRMH = 0.67; 95 % CI: 0.52–0.87; p = 0.002); heterogeneity was not a problem.ConclusionTogether with a photoradiometer and education, intensive phototherapy can significantly reduce the ET rate. Inborn Hospital A had four times as many admissions for jaundice as Inborn Hospital B, and did not reduce ET until it received additional high intensity machines. The results highlight the importance of providing enough intensive phototherapy units to treat all neonates requiring high intensity treatment for a full course.Trial registrationAustralian New Zealand Clinical Trials Registry ACTRN12615001171505, 2 November 2015.

THREE HUNDRED SIXTY DEGREE PHOTOTHERAPY VERSUS CONVENTIONAL PHOTOTHERAPY IN NEONATAL INDIRECT HYPERBILIRUBINEMIA

Background&#x0D; Phototherapy is the mainstay of treatment of hyperbilirubinemia. The efficacy of phototherapy depended on the light spectrum (wavelength), intensity of and type of the light and surface area of the infant exposed to phototherapy and distance of the light from the baby. A measure of the efficacy of phototherapy is the rate of decline in total serum bilirubin per hour and the dramatic reduction in the number of exchange transfusions being performed.&#x0D; Objectives&#x0D; To determine the efficacy of increasing surface area of phototherapy (360◦) compared with conventional single surface fluorescent phototherapy.&#x0D; Patients and Methods&#x0D; A prospective study was done for 214 neonates, who were admitted to neonatal care unit at Raprin teaching hospital in a period of 6 months from the first of January till the thirty of July 2013. Neonates were presented with significant indirect hyperbilirubinemia that needed phototherapy, less than two weeks of age were included in this study. According to the level of total serum bilirubin and availability of highly intensive phototherapy the cases were divided in to two groups.&#x0D; Results&#x0D; The mean starting TSB in group I was 15.03±2.53 mg/dl while in group II 19.65±3.34 mg/dl and the percentage of decline after 12 hour in group I was 19.17±13.08%, while in group II was 39.37±10.31% , and it was statistically significant (p&lt;0.001). The decline rate after 12 hour ,regarding group I was 0.23 ± 0.21 mg/dl/hr, while in group II was 0.50 ± 0.33 mg/dl/hr which was statistically significant (p&lt;0.001). There was a significant decline in the number of exchange transfusion in 2013 when the highly intensive 360 degree phototherapy started to be used.&#x0D; Conclusion&#x0D; Increasing surface area of exposure increase the rate of reducing of the serum bilirubin, and decreases rate of exchange transfusion as well.

Cochrane Review: Prophylactic phototherapy for preventing jaundice in preterm or low birth weight infants

Low birth weight and premature infants are at major risk for exaggerated hyperbilirubinaemia and jaundice that can lead to bilirubin encephalopathy. Phototherapy is the most common treatment for neonatal hyperbilirubinaemia and could be most effective in preventing the sequelae of hyperbilirubinaemia if initiated prophylactically. To evaluate the efficacy and safety of prophylactic phototherapy for preterm (< 37 weeks gestational age) or low birth weight infants (birth weight < 2500 g). We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3) on 31 March 2011, MEDLINE (1950 to 31 March 2011), EMBASE (1980 to 31 March 2011) and CINAHL (1982 to 31 March 2011). Randomised controlled trials or quasi-randomised controlled studies evaluating the effects of prophylactic phototherapy for preterm or low birth weight infants. Two authors independently obtained data from published articles. We performed fixed-effect meta-analysis for the outcomes: rate of exchange transfusion, cerebral palsy or other neurodevelopmental impairment, peak serum bilirubin level and all-cause mortality. Nine studies of 3449 participants were included. The rate of exchange transfusion was reduced in one study with liberal transfusion criteria (risk ratio (RR) 0.20; 95% confidence interval (CI) 0.13 to 0.31) but not in the other two more recent studies with stringent criteria (typical RR 0.66; 95% CI 0.19 to 2.28). There was no statistically significant difference in the rate of cerebral palsy (typical RR 0.96; 95% CI 0.50 to 1.85; two studies, 756 participants). However, one large study that reported on neurodevelopmental impairment (a composite outcome including cerebral palsy) found a slightly lower rate of neurodevelopmental impairment with prophylactic phototherapy (RR 0.85; 95% CI 0.74 to 0.99; 1804 participants). The prophylactic phototherapy group had lower peak bilirubin levels (mean difference (MD) -2.73; 95% CI -2.89 to -2.57; six studies, 2319 participants) and had fewer neonates with peak unconjugated serum bilirubin levels > 10 mg/dl (typical RR 0.27; 95% CI 0.22 to 0.33; three studies, 1090 participants) or peak unconjugated serum bilirubin levels > 15 mg/dl (typical RR 0.13; 95% CI 0.07 to 0.23; four studies, 1116 participants). There was no statistically significant difference in the rate of all-cause mortality between the two groups (typical RR 1.08; 95% CI 0.93 to 1.26; four studies, 3044 participants). Prophylactic phototherapy helps to maintain a lower serum bilirubin concentration and may have an effect on the rate of exchange transfusion and the risk of neurodevelopmental impairment. However, further well-designed studies are needed to determine the efficacy and safety of prophylactic phototherapy on long-term outcomes including neurodevelopmental outcomes.

The efficacy of the use of intravenous human immunoglobulin in Brazilian newborns with rhesus hemolytic disease: a randomized double‐blind trial

The purpose of this study was to evaluate the efficacy of intravenous human immunoglobulin (IVIG) in the presence of high-intensity phototherapy in decreasing the need for exchange transfusion in newborns with rhesus hemolytic disease. We performed a randomized, double-blind, placebo-controlled trial. The trial included D+ newborns born at 32 weeks of gestational age or later with a positive direct antiglobulin test and whose mothers were Rh-alloimmunized and did or did not receive intrauterine transfusion. The newborns were randomly assigned to receive either IVIG at a dose of 500 mg/kg or placebo (saline solution, 10 mL/kg) during the first 6 hours of life. The primary outcome was the need for exchange transfusion. The criteria for exchange transfusion were total serum bilirubin (TSB) level at or above 340 µmol/L (20 mg/dL) or increasing by 8.5 µmol/L/hr (0.5 mg/dL/hr) despite intensive phototherapy. The trial included 92 newborns. There was no difference in the rate of exchange transfusion between groups: 6 of 46 (13%) in the IVIG group versus 7 of 46 (15.2%) in the placebo group (p = 0.765). There were no significant differences between groups with respect to their need for exchange transfusion, phototherapy time, peak bilirubin, or length of hospital stay. There were no adverse events related to the drug or the form of administration. Nonspecific human immunoglobulin was not effective in preventing the need for exchange transfusion in neonates with rhesus hemolytic disease.
