- Ministerio de Salud This is catalyzed by the enzyme uridine diphosphate-glucuronyltransferase (UGT1A1). [19][20], Indirect hyperbilirubinemia due to decreased bilirubin clearance usually results from quantitative or qualitative defects in the uridine diphosphate glucuronosyltransferase (UGT) enzyme. [67] However, in developing nations, the estimated occurrence of kernicterus is much higher. Increased incidence of neonatal hyperbilirubinemia at 3,100 m in Colorado.

The genetic basis of the reduced expression of bilirubin UDP-glucuronosyltransferase 1 in Gilbert's syndrome. It is important to maintain adequate hydration and ensure normal urine output as most bilirubin is excreted in the urine as lumirubin. HS, also known as Minkowski Chauffard disease, is the most common RBC membrane defect caused by mutations in RBC membrane proteins. Cursa con bilirrubina directa mayor a 2 mg/dl.

EFEITO DE UM ÚNICO EVENTO ESTRESSOR NO PERÍODO NEONATAL SOBRE O COMPORTAMENTO SEXUAL DE RATOS. Gastrointestinal obstruction promotes increased bilirubin recycling by augmenting the enterohepatic circulation. Phototherapy (PT) remains the first-line treatment for managing pathological unconjugated hyperbilirubinemia. However, with the advent of IVIG use and double volume exchange transfusion, the prognosis for this disease has greatly improved in recent years. [37] The Kasai operation involves removing the atretic biliary ducts and fibrous plate and Roux-en-Y anastomosis of jejunum with the remaining ducts to provide an alternative pathway for biliary drainage. [16] Most cases are transmitted as AD traits caused by mutations in RBCs structural membrane protein. Complications of ET include electrolyte abnormalities like hypocalcemia and hyperkalemia, cardiac arrhythmias, thrombocytopenia, blood-borne infections, portal vein thrombosis, graft versus host disease, and necrotizing enterocolitis (NEC). Preterm infants and those born with congenital enzyme deficiencies are particularly prone to the harmful effects of unconjugated bilirubin on the central nervous system. Other features of this disorder are renal Fanconi syndrome, hepatomegaly, coagulation abnormality, and the risk of hepatocellular carcinoma in untreated patients.[49]. Subnotificação e Epidemiologia Dos Casos De Febre De Mayaro No Tocantins, 2009-2019 . [56] Gestational alloimmune liver disease (GALD), which causes almost all neonatal hemochromatosis cases, is a fulminant alloimmune disorder and results from intra-hepatic and extra-hepatic iron deposition resulting in liver failure. Fogarty M, Osborn DA, Askie L, Seidler AL, Hunter K, Lui K, Simes J, Tarnow-Mordi W. Delayed vs early umbilical cord clamping for preterm infants: a systematic review and meta-analysis. [28], The majority of infants with clinical UHB have a combination of two or more factors discussed earlier. [93] PT has been considered relatively safe, but recent evidence points towards possible long-term side effects. Roelofsen H, van der Veere CN, Ottenhoff R, Schoemaker B, Jansen PL, Oude Elferink RP. Histopathological interpretation by an experienced pathologist will help to identify the correct diagnosis in 90% to 95% of cases and may prevent unnecessary interventions in patients with intrahepatic cholestasis. Patients suspected of neonatal cholestasis should be referred to a pediatric gastroenterologist at the earliest. [104] Infectious causes of cholestasis would be treated with specific anti-microbial, whereas treatment with cholic acid and chenodeoxycholic acid is often curative for many BASDs. Adverse events associated with exchange transfusion in healthy and ill newborns. Esta coloración avanza de manera craneocaudal. UTI is also a significant cause of CHB in neonates, and a urine culture should be included as part of diagnostic evaluation. [44] With an incidence of 1 in 30,000 live births, ALGS is the most common cause of familial intrahepatic cholestasis. [12] The clinical presentation varies depending on the variant, and some newborns may develop severe hyperbilirubinemia and bilirubin encephalopathy. Interestingly, CHB in patients with ALGS may resolve with age. Rotina Criana 2014_versao sem anexos. [26] UHB in congenital hypothyroidism is related to decreased hepatic uptake of bilirubin, impaired UGT activity, and sluggish gut motility. In a rare situation, high carotene levels may cause yellowish discoloration of the skin and may be mistaken to be hyperbilirubinemia. It is usually seen in neonates with elevated serum conjugated bilirubin levels. Physiological jaundice typically appears after 24 hours of age, peaks at around 48-96 hours, and resolves by two to three weeks in full-term infants. Quase toda a hiperbilirrubinemia no período neonatal . • Patrón de alimentación mal establecido. Leung AK, Sauve RS.

Similarly, patients with bile acid synthesis disorder (BASD) have an excellent prognosis as they respond very well to medical treatment. Larissa Pires Marquite da Silva 19/11/2021 A hiperbilirrubinemia é caracterizada pelo acúmulo de bilirrubina nos tecidos, levando a um sinal muito frequente no período neonatal: a icterícia. We conducted a systematic review and meta-analysis of the studies . Hankø E, Hansen TW, Almaas R, Lindstad J, Rootwelt T. Bilirubin induces apoptosis and necrosis in human NT2-N neurons. Infants with bilirubin encephalopathy demonstrate hyperintense signals on T1-weighted sequences in the acute stage that eventually becomes hyperintense on T2-weighted sequences as the disease evolves. Patients present with signs of liver failure in the form of hypoglycemic, coagulopathy, hypoalbuminemia, cholestatic jaundice, edema, and elevated liver enzymes. Fórmula da penicilina, o primeiro antibiótico natural, que foi descuberto por Alexander Fleming en 1928.

Hyperbilirubinemia in the newborn infant > or =35 weeks' gestation: an update with clarifications. The term jaundice derives from the French word "jaune," which means yellow. Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of three genetic disorders that present with cholestasis. [2], Jaundice is considered pathological if it presents on the first day of life, TSB is more than the 95th centile for age based on age-specific bilirubin nomograms, levels rise by more than 5 mg/dL/day or more than 0.2 mg/dL/hour, or jaundice persists beyond 2 to 3 weeks in full-term infants.[8]. BASDs are an uncommon cause of cholestasis, but many of these are curable with medical therapy alone. Fototerapia, Recém-Nascido, Icterícia Neonatal, Alojamento Conjunto. Prevention of Rh D alloimmunization. Aula 6 - Icterícia Neonatal 2022-12-28 • 0 exibições 199.3 KB 3 páginas pdf. La ictericia puede ser fisiológica (niveles menor de 12 mg/dl en recién nacido a término y de 15 mg/dl en prematuros). Pathological jaundice in neonates is related to increased production of bilirubin in RES, impaired hepatic uptake, deficient conjugation of bilirubin, and/or enhanced enterohepatic circulation of bilirubin. A unique feature of DJS is the presence of black liver and excretion of coproporphyrin 1 in urine. Una ictericia será patológica (6% de recién nacidos) cuando se inicie en las primeras 24 horas, se acompañe de otros síntomas, la bi-lirrubina aumente más de 5 mg/dL diarios, sobrepase los límites definidos para ictericia fisiológica, la fracción directa sea superior a 2 mg/dL o dure más de una semana en el RN a término (excepto si recibe lactancia ma-terna, en cuyo caso puede durar tres sema-nas o más) o más de dos semanas en el pre-término. ACOG practice bulletin. The duration of exposure to bilirubin and the amount of bilirubin in the brain determines the severity of brain damage. Bilirubin-G corresponds to bilirubin glucuronate, where the donor is uridine diphosphate glucuronic acid (UDP-GA). Ictericia neonatal 380. [88]  Bilirubin-albumin ratio(B/A) ratio is, therefore, an additional tool that may predict the risk of kernicterus and may serve as an alternative guide to exchange transfusion. [23], Breast milk jaundice and breastfeeding jaundice are two other common etiologies of UHB in newborns. O aleitamento materno, os RNs fiquasefl termo e a presença de icterícia à data da alta sªo factores de risco importantes. [69] The most common identifiable cause of cholestatic jaundice in the neonatal period is  Biliary atresia accounting for about 25% to 40% of all cases, followed by infections and TPN-induced cholestasis. DOI: 10.1101/2022.12.14.22283348. Patients with GALD appear to respond well to IVIG and double volume exchange transfusion. Es muy común afectando al menos al 60% de los neonatos a término y al 80% de los nacidos prematuros y siendo la principal causa de ingreso hospitalario en la primera semana de vida. The pathognomonic histopathological features of other cholestatic disorders include periodic acid- Schiff (PAS)-positive granules in alpha-1 antitrypsin deficiency, paucity of bile ducts in Alagille syndrome, necrosis, and inflammation around duct seen in sclerosing cholangitis. [46] In developing nations where newborn screening with immunoreactive trypsinogen is unavailable, neonatal cholestasis may be the first clue to the diagnosis. Brouillard RP. Novel mechanism of fetal hepatocyte injury in congenital alloimmune hepatitis involves the terminal complement cascade. PT is very effective in reducing TSB to safe levels and reduces the risk of bilirubin toxicity and the need for exchange transfusion. Bhutani VK, Wong R. Bilirubin-induced neurologic dysfunction (BIND). [9] ABO incompatibility between mother and fetus exists in about 15% of pregnancies, but HDN due to ABO incompatibility is seen only in 4% of newborns with ABO incompatibility. Whatever happened to "neonatal hepatitis"? Hyperbilirubinemia and early discharge. It is thought to be mainly due to inhibition of the UGT enzyme by pregnanediol and deconjugation of conjugated bilirubin in the intestines by beta-glucuronidase present in breast milk. [30] The efficacy of phototherapy depends on the dose and wavelength of light used as well as the surface area of the infant's body exposed to it. Miscellaneous: Idiopathic neonatal hepatitis, parenteral nutrition induced cholestasis, gestational alloimmune liver disease/neonatal hemochromatosis, hypotension, Biliary atresia (BA) is the most common cause of conjugated hyperbilirubinemia in infants. [85] Therefore clinically significant jaundice should always be confirmed with a TSB or transcutaneous bilirubin. Incluídos todos os nascidos no serviço com IG maior ou igual a 35 semanas, sem anomalias congênitas, e admitidos no AC. Itoh S, Okada H, Kuboi T, Kusaka T. Phototherapy for neonatal hyperbilirubinemia. 'Understanding NICE guidance' - a summary for patients and carers. Antibiótico. [105] The prognosis for most of the other types of cholestasis is often not very favorable, and many of these patients will require multidisciplinary interventions. [50] Types 1 and 2 usually manifest in the neonatal period, while type 3 presents later in infancy.

Es el intercambio de forma fraccionada y lenta de un volumen de sangre del orden del doble de la volemia estimada del recién nacido. Introducción: existen dos términos para describir el crecimiento fetal excesivo: "grande para la edad gestacional" (GEG) y "macrosomía".GEG generalmente implica un peso al nacer superior al percentil 90 para una edad gestacional determinada. [71], Bilirubin is produced from the catabolism of heme, a breakdown product of hemoglobin, in the reticuloendothelial system (RES). Radiology is often necessary as part of the workup of neonatal cholestasis. Hegyi T, Goldie E, Hiatt M. The protective role of bilirubin in oxygen-radical diseases of the preterm infant. [62] Newborns with Southeast and Far East Asian ancestry have higher recorded TSB levels than their White and African counterparts. Identify pathological jaundice and differentiate it from physiological jaundice. Patients with Crigler-Najjar type 1 carry a poor prognosis and require liver transplantation for a definitive cure. [8] Major risk factors in newborns over 35 weeks gestation include pre-discharge bilirubin in the high-risk zone, jaundice observed in the first 24 hours, blood group incompatibility, gestational age 35 to 36 weeks, a previous sibling who received phototherapy, cephalhematoma or significant bruising, exclusive breastfeeding and east Asian race. Gilbert syndrome is the most common of these and results from a mutation in the UGT1A1 gene resulting in decreased UGT production leading to unconjugated hyperbilirubinemia. NOC • Rol ser padres. Nurses and parents are often the first to notice jaundice in a newborn. • Pérdida de peso anormal (> 7-8% en el neonato con lactancia materna; 15% en el neonato a término). [36] Early diagnosis is critical to maximizing the response to a Kasai operation (hepatic portoenterostomy). Sgro M, Campbell D, Shah V. Incidence and causes of severe neonatal hyperbilirubinemia in Canada. The UGT enzyme in a newborn has an activity of about 1% of the adult level. [37] If the surgery is delayed by 90 days of life, less than 25% of patients are reported to respond, compared to surgery performed within 60 days when more than 70% of patients will establish adequate bile flow. Este tópico aborda o reconhecimento e o manejo da icterícia neonatal precoce, que é mais comumente causada por hiperbilirrubinemia não conjugada. La ictericia se define como coloración amarillenta cutánea y aparece con motivos principalmente fisiológicos en un alto por - centaje de recién nacidos. Phototherapy and exchange transfusion are the mainstay of treatment for patients with unconjugated hyperbilirubinemia. FIFA Sound) [100][101] Phototherapy should resume after exchange transfusion until the bilirubin reaches a level where it can be safely discontinued. Newborns with galactosemia present with cholestatic jaundice, cataracts, hepatomegaly, failure to thrive, renal tubular acidosis, and Escherichia coli sepsis after the ingestion of galactose from milk. Recommended workup for identifying a hemolytic disease as the cause of unconjugated hyperbilirubinemia include maternal/neonatal blood type, Coombs test, complete blood cell (CBC), reticulocyte count, blood smear, and G6PD. Nurses play a vital role by monitoring treatments, educating parents, and keeping the team apprised about changes in the patient's condition. In PFIC2 patients, the histopathology is similar except that altered liver architecture and extensive lobular and portal fibrosis with inflammation are more common. Microcirculatory changes in the liver, a direct effect of bacterial products, and toxins released by bacteria are thought to be the possible mechanism of cholestasis in patients with UTI.[43]. In most cases, it is a mild, transient, and self-limiting condition and is referred to as "physiological Jaundice." [99] It is indicated when there is a failure of response to PT, or the initial TSB levels are in the exchange range based on the nomogram. Se informa prurito cuando la ictericia obstructiva dura más de tres a cuatro semanas, independientemente de su causa. Long-standing cholestasis may also lead to failure to thrive and fat-soluble vitamin deficiencies. METHODS: Retrospective study with newborns = 35 weeks in a Tertiary Hospital RC from October to December 2017. Healthy adults have a normal TSB level of less than 1mg/dl in contrast to neonates, where TSB levels are physiologically higher. Etiologies of conjugated hyperbilirubinemia in infancy: a systematic review of 1692 subjects. Townsend S, Newsome P, Turner AM. License: Creative Commons. [51] Aagenaes syndrome, also known as lymphedema cholestasis syndrome (LCS), is another type of idiopathic familial intrahepatic cholestasis syndrome characterized by neonatal cholestasis and lymphedema in lower extremities. Patients with Crigler-Najjar syndrome type 2 retain some of the activity of UGT enzymes. [15] Hereditary elliptocytosis is another type of RBC membrane defect that is mostly asymptomatic but rarely does cause UHB in the neonatal period. Resid Pediatr. O grupo tratado teve menor IG (38 x 39 semanas), maior bilirrubina em sangue de cordão (2 x 1,5mg/dL), maior perda de peso (7 x 6%), incompatibilidade ABO mais frequente (35 x 10%) e internação mais prolongada (79 x 50 horas). Related Papers. Every health care provider involved in the care of a jaundiced newborn needs to be updated on current evidence-based management approaches. [58] The term idiopathic neonatal hepatitis is used when the etiology of neonatal cholestasis cannot be ascertained after an extensive diagnostic workup. Morotti RA, Jain D.

Despite advances in care and management of hyperbilirubinemia, it remains a significant cause of morbidity and mortality.[6]. Methods: Here, we used Transposon Sequencing of saturated banks of mutants (TnSeq) to evaluate E. coli K1 genetic fitness in . [7] Breastfeeding failure leads to decreased intestinal motility and decreases the elimination of bilirubin in the stool or meconium. Failure to identify and treat this entity may result in bilirubin encephalopathy and associated neurological sequelae. These signs should be looked for during physical exams that may often provide a clue to diagnosis and aid in directing specific work-up. Most of these patients will need a battery of investigation, and once a cause of cholestasis is identified, more referrals would be warranted. Temas para Tesis de Ictericia Neonatal - TFG - TFM. Crigler-Najjar type I & II, and Gilbert syndrome. American College of Obstetrics and Gynecology. Finally, liver biopsy is usually considered the gold standard for diagnosing neonatal cholestasis. [76][77] These mechanisms are implicated in the pathogenesis of bilirubin toxicity that clinically manifests as bilirubin-induced neurologic dysfunction (BIND) and bilirubin encephalopathy. Diagnosis of Conjugated Hyperbilirubinemia. In HDN, due to ABO incompatibility, preformed maternal anti-A and anti-B antibodies of immunoglobulin (Ig) G subclass cross the placenta and cause hemolysis and UHB in newborns with blood type A, B, or AB. First, heme is converted to biliverdin, releasing iron and carbon monoxide via the action of enzyme heme oxygenase. Physiological jaundice accounts for 75% of neonatal hyperbilirubinemia and results from a physiological alteration in neonatal bilirubin metabolism. You can download the paper by clicking the button above. [68], Conjugated hyperbilirubinemia is much less common compared to UCH, with a frequency of around 1 in  2500 term infants. Abstract Introdução: A icterícia neonatal, achado comum nos recém-nascidos, ocorrendo em até 60% dos casos, decorrente da hiperbilirrubinemia, com níveis séricos >5mg/dL. Gottesman LE, Del Vecchio MT, Aronoff SC. The risk of recurrence in subsequent pregnancies is almost 90%, and GALD can result in fetal or neonatal deaths. Conjugated bilirubin is water-soluble and is then excreted in bile and into the gastrointestinal (GI) tract, where it is mostly excreted in feces after being metabolized by intestinal bacterial flora. Poland RL, Odell GB. Jackson JC. Maternal, gestational, neonatal clinical data and care practices were evaluated. [45] Few patients with cystic fibrosis (CF) can present with features of cholestasis because of abnormal bile that plugs the bile ducts.

Historically, the prognosis for gestational alloimmune liver disease (GALD) was poor, with up to 80% mortality without liver transplantation. 2. FOTOTERAPIA ICTERICIA NEONATAL PDF. [35] The etiology of BA is not well understood, but genetic factors along with viral infection, toxins, chronic inflammatory and autoimmune injury to bile ducts seem to play a role in its pathogenesis. Pediatra y neumóloga infantil septiembre 2022 La ictericia neonatal es cuando la piel y los ojos del bebé presentan una coloración amarillenta, que indica que puede haber niveles elevados de bilirrubina en la sangre, siendo generalmente causadas por alteraciones en el metabolismo de la bilirrubina y no en todos los casos se considera un problema. Evaluation for pallor, petechiae, cephalhematoma, subgaleal bleed, extensive bruising, hepatosplenomegaly, weight loss, signs of dehydration needs to be done. IDMs often have polycythemia which is mainly responsible for the increased incidence of jaundice in these infants. Additional tests like TORCH titers, urine cultures, viral cultures, serologic titers, Newborn screening results, specific tests for inborn errors of metabolism,  alpha-1 antitrypsin phenotype, and specific genetics tests may be needed depending on the scenario. After discharge from the birth hospital, parents need to be educated by the nurses, pediatricians, obstetricians, and the family practice providers to monitor for jaundice and seek medical care if it worsens. It is the most commonly encountered medical problem in the first two weeks of life and a common cause of readmission to the hospital after birth. PFIC1 is caused by a mutation in the ATP8B1 gene, which encodes FIC1 protein, whereas PFIC2 is caused by a mutation in the ABCB11 gene, which encodes for the bile salt excretory protein (BSEP). [82] Although not diagnostic of any disorder, the prominence of hepatic erythropoiesis is seen more frequently in cholestasis of infectious etiology. The American College of Obstetricians and Gynecologists (ACOG) has recommended that all Rh-negative pregnant women receive anti-D immune globulin at 28 weeks of gestation and again following delivery if the infant is Rh-positive/unknown. He specified its objectives and decided on the types of . Features of Alagille syndrome in 92 patients: frequency and relation to prognosis. The outcome and prognosis of patients with biliary atresia are significantly improved by early diagnosis and surgery within 60 days of life. Rebound bilirubin levels in infants receiving phototherapy. Most cases are benign with an excellent prognosis and resolve with or without treatment. ), which permits others to distribute the work, provided that the article is not altered or used commercially. [92] During phototherapy, the eyes of the newborn must be covered to avoid retinal injury. Moore LG, Newberry MA, Freeby GM, Crnic LS. Galactosemia, fructosemia, and tyrosinemia type 1 are a few of the inborn errors of metabolism known to cause cholestasis in neonates. Siéntase libre de enviar sugerencias.

The level at which unconjugated bilirubin becomes neurotoxic is unclear, and kernicterus has been reported in infants in the absence of markedly elevated levels of bilirubin on autopsy. Effect of the ratio of bilirubin to serum albumin. However, patients suspected of genetic causes of hyperbilirubinemia may need consultations and follow-ups with a pediatric gastroenterologist, hematologist, and medical geneticist. [24][25], Other miscellaneous causes of UHB include IDM, gastrointestinal obstruction, congenital hypothyroidism, certain medications. infants who are still jaundiced at ages 3to 4 weeks and sometimes beyond but,to date, there are limited published dataon how often this phenomenon occurs.In Fig 2, we provide the rst documen-tation, with percentiles, of the naturalhistory of bilirubinemia in a large pop-ulation of healthy, breastfeeding new-borns up to age 28 6 3 days. When exposed to oxidant stressors like illness, certain medications, dyes, and foods like fava beans, G6PD deficient RBCs are hemolyzed, causing anemia and hyperbilirubinemia.

Guidelines for detection, management and prevention of hyperbilirubinemia in term and late preterm newborn infants (35 or more weeks' gestation) - Summary. Treasure Island (FL): StatPearls Publishing; 2022 Jan-. The glucose-6 phosphatase dehydrogenase (G6PD) enzyme deficiency is the most common RBC enzyme defect and is transmitted as an X-linked recessive trait. Neonatal Indirect Hyperbilirubinemia. El tema que elijas para crear la investigación de tu tesis, ha de ser algo que sea de tu agrado y se te haga cómodo de investigar. It is estimated that about 60% of term and 80% of preterm newborns will present with clinical jaundice with TSB >5 mg/dl. Metabolic causes of cholestasis would typically respond to the improvement of the primary disorder and liver functions. [72] As discussed in prior sections, certain etiologies of neonatal cholestasis have multi-system involvement. Ictericia neonatal, pág.376). Polycythemia is another entity associated with an increased risk of UHB in newborns. Failure to identify and treat this entity may result in bilirubin encephalopathy and associated neurological sequelae. However, during subsequent pregnancies, the antibody class switch produces IgG antibodies which can cross the placenta, causing RBC hemolysis in the fetus with Rh-positive blood. Icterícia neonatal: fatores associados à necessidade de fototerapia em alojamento conjunto. An evidence-based review of important issues concerning neonatal hyperbilirubinemia. With treatment, the prognosis for most types of unconjugated hyperbilirubinemia is excellent. Davit-Spraul A, Gonzales E, Baussan C, Jacquemin E. Progressive familial intrahepatic cholestasis.

Jaundice from etiologies that carry poor prognosis often requires multidisciplinary interventions, and parents should be adequately counseled and educated. Parenteral nutrition-associated cholestasis (PNAC) is an important iatrogenic cause of cholestasis recognized most commonly in preterm infants managed with parenteral nutrition (PN). Maisels MJ, Bhutani VK, Bogen D, Newman TB, Stark AR, Watchko JF. [34] The incidence of BA varies from region to region. Anderson NB, Calkins KL. [29], Conjugated Hyperbilirubinemia(CHB) or Direct Hyperbilirubinemia, Conjugated hyperbilirubinemia, also referred to as neonatal cholestasis, is characterized by elevation of serum conjugated/direct) bilirubin (> 1.0 mg/dL) and is due to impaired hepatobiliary function. Exaggerated hemolysis, either immune or non-immune mediated, is the most common cause of pathological hyperbilirubinemia in newborns. McDonald SJ, Middleton P, Dowswell T, Morris PS. Desfecho: uso de fototerapia. [51], The evaluation of the neonate with jaundice starts with a detailed history, including birth history, family history, the onset of jaundice, and maternal serologies.

Increasing the dose of PT can be achieved by placing phototherapy units at the minimum safe distance from the infant and increasing the number of units used. Neonatal cholestasis may be a presenting feature in hereditary tyrosinemia type 1, another AR disorder caused by deficiency of enzyme fumarylacetoacetate hydroxylase. [75] Bilirubin also impairs tyrosine uptake and alters the normal functioning of  N-methyl-D-aspartate–receptor ion channels. G6PD protects RBCs against oxidative damage by generating NADPH (nicotinamide adenine dinucleotide phosphate hydrogenase) from NADP (nicotinamide adenine dinucleotide phosphate). Phototherapy is started based on risk factors and the TSB levels on the bilirubin nomogram. As such most hospitals in the U.S have instituted their own guidelines for the use of phototherapy and exchange transfusion in preterm infants based on birth weight or gestational age.

[40] Neonatal cholelithiasis is also a rare entity that can cause significant direct hyperbilirubinemia in neonates. Since most of the total body bilirubin lies in the extravascular compartment complications, TSB levels immediately following ET is about 60% of the pre-exchange level that later increase to 70 to 80% of pre-exchange levels as a result of equilibrium with an extravascular moiety of bilirubin.

[60] Around 15% of breast-fed infants will develop UCH lasting for more than three weeks. However, it is imperative to distinguish this from a more severe form called "pathological jaundice." Clearance of bilirubin is also compromised due to impaired activity of uridine diphosphate glucuronosyltransferase (UGT), the enzyme needed for bilirubin conjugation. Other factors such as sepsis, and necrotizing enterocolitis, appear to potentiate liver injury. Health care professionals taking care of newborn needs to be aware of this.
