Żółtaczka noworodkowa
Rokowania, prognozy i postęp choroby

Żółtaczka noworodkowa (hiperbilirubinemia) dotyczy ponad 80% noworodków, z reguły ustępując samoistnie w ciągu 2-3 tygodni, jednak utrzymująca się ponad 3 tygodnie wymaga dalszej diagnostyki. Najpoważniejszym powikłaniem jest encefalopatia bilirubinowa i kernicterus, prowadzące do trwałego uszkodzenia neurologicznego, choć występują rzadko (kernicterus u 1/100 000 niemowląt). Ciężka hiperbilirubinemia definiowana jest jako TSB >20 mg/dl (342,1 μmol/l) i dotyczy <2% noworodków donoszonych. Czynniki ryzyka obejmują wiek matki >35 lat (OR 8,8), płeć męską (OR 4,3), wcześniactwo, niezgodność grup krwi ABO, poród drogami natury oraz zamieszkanie w obszarach miejskich. Metoda Kramera, choć ma dobrą swoistość (86,1%) i PPV (89,8%), cechuje się umiarkowaną czułością (70,5%) i nie powinna być stosowana jako jedyne narzędzie przesiewowe. Nowoczesne metody oparte na biomarkerach metabolomicznych oraz sztucznej inteligencji (np. algorytm XGBoost z dokładnością 99,63%) oferują obiecujące narzędzia do wczesnej diagnostyki i prognozowania czasu trwania fototerapii.

Prognoza żółtaczki noworodkowej

Żółtaczka noworodkowa (hiperbilirubinemia) jest powszechnym zjawiskiem występującym u ponad 80% noworodków, jednak w większości przypadków rokowanie jest dobre, o ile pacjent otrzyma odpowiednie leczenie zgodnie z przyjętymi wytycznymi. 12 W typowych przypadkach żółtaczka ustępuje samoistnie w ciągu 2 tygodni u niemowląt karmionych mlekiem modyfikowanym oraz w ciągu 2-3 tygodni u niemowląt karmionych piersią. Jeśli żółtaczka utrzymuje się dłużej niż 3 tygodnie, konieczna jest dalsza ocena medyczna. 34

Ryzyko powikłań

Najpoważniejszym powikłaniem żółtaczki noworodkowej jest encefalopatia bilirubinowa i kernicterus (przewlekła encefalopatia bilirubinowa), które mogą prowadzić do trwałego uszkodzenia neurologicznego. Chociaż żółtaczka noworodkowa jest powszechna, te ciężkie powikłania występują rzadko. 5 Kernicterus rozwija się u jednego na 100 000 niemowląt i objawia się atetozowym mózgowym porażeniem dziecięcym, dysfunkcją słuchową, dysplazją zębów, porażeniem spojrzenia ku górze oraz zmiennym stopniem niepełnosprawności intelektualnej. 6

W badaniach wykazano, że mniej niż 5% zdrowych noworodków urodzonych w terminie z poziomem bilirubiny całkowitej (TSB) większym niż 30 mg/dl (513,1 μmol/l) rozwija ostrą encefalopatię bilirubinową lub kernicterus. 7 Ciężka hiperbilirubinemia (poziom bilirubiny całkowitej [TSB] powyżej 20 mg/dl [342,1 μmol/l]) występuje u mniej niż 2% noworodków urodzonych w terminie. 8

Śmierć z powodu fizjologicznej żółtaczki noworodkowej jako takiej nie powinna występować. Zgon z powodu kernicterusu może wystąpić, szczególnie w krajach o mniej rozwiniętych systemach opieki medycznej. W badaniu z wiejskiej Nigerii, 31% niemowląt z kliniczną żółtaczką miało niedobór G6PD, a 36% tych niemowląt z niedoborem G6PD zmarło z powodu prawdopodobnego kernicterusu w porównaniu z tylko 3% niemowląt z prawidłowym wynikiem badania przesiewowego G6PD. 9

Czynniki ryzyka ciężkiej żółtaczki

Rozpoznanie niemowląt z wysokim ryzykiem rozwoju istotnej żółtaczki jest szczególnie ważne w erze rutynowych wczesnych wypisów ze szpitala. Badania prospektywne wskazują, że indywidualna ocena ryzyka przy wypisie w połączeniu z pomiarem bilirubiny całkowitej w pierwszej dobie życia ma wartość w identyfikacji niemowląt narażonych na większe ryzyko żółtaczki noworodkowej. 10

Istotne czynniki ryzyka związane z większym prawdopodobieństwem wystąpienia żółtaczki noworodkowej obejmują:

  • Wiek matki powyżej 35 lat – prawdopodobieństwo wystąpienia żółtaczki u noworodka jest 8,8 razy wyższe u matek powyżej 35 roku życia w porównaniu do tych poniżej 25 lat 11
  • Płeć męska – noworodki płci męskiej mają 4,3 razy większe prawdopodobieństwo wystąpienia żółtaczki noworodkowej niż noworodki płci żeńskiej 12
  • Wcześniactwo – wcześniaki są niemal czterokrotnie bardziej podatne na żółtaczkę w porównaniu do noworodków urodzonych w terminie, ze względu na niedojrzałą wątrobę, która może nie być w stanie skutecznie przetwarzać i wydalać bilirubiny 13
  • Niezgodność grup krwi ABO – noworodki z niezgodnością ABO są bardziej narażone na rozwój żółtaczki noworodkowej w porównaniu do tych bez takiej niezgodności 14
  • Poród drogami natury – badania wykazały, że poród przez cesarskie cięcie był w 76% ochronny wobec żółtaczki noworodkowej w porównaniu z porodem pochwowym 15
  • Zamieszkanie w obszarach miejskich – mieszkańcy obszarów miejskich byli 2,4 razy bardziej narażeni na wystąpienie żółtaczki noworodkowej niż osoby z obszarów wiejskich 16

Znaczenie wczesnego wykrywania

Znaczenie wczesnego wykrywania żółtaczki noworodkowej jest niezwykle istotne ze względu na potencjalne poważne powikłania u niemowląt. 17 W retrospektywnym badaniu z Wielkiej Brytanii, większość niemowląt, u których później zdiagnozowano kernicterus, została wypisana do domu ze szpitala porodowego, a między rozpoznaniem żółtaczki a ponownym przyjęciem wystąpiło opóźnienie w zakresie 26-102 godzin. 18

Aby skutecznie zapobiegać, diagnozować i leczyć żółtaczkę noworodkową, wysiłki powinny koncentrować się głównie na zarządzaniu niezgodnością ABO i wczesnym wykrywaniu wcześniactwa. Dodatkowo szczególną uwagę należy zwrócić na noworodki urodzone drogą pochwową, te z matkami powyżej 35 roku życia oraz mieszkające w obszarach miejskich, ponieważ są one bardziej narażone na rozwój żółtaczki. Ścisłe monitorowanie par matka-dziecko z grupy wysokiego ryzyka w okresie przedporodowym i poporodowym, wraz z wczesną interwencją, ma kluczowe znaczenie dla zmniejszenia nasilenia żółtaczki noworodkowej. 19

Nowoczesne metody prognozowania żółtaczki

Metoda Kramera

Metoda Kramera jest tradycyjną techniką oceny wizualnej nasilenia żółtaczki. Badania wykazały, że metoda Kramera ma dobrą wartość predykcyjną dodatnią (PPV – 89,8%), ale ze względu na niską czułość (70,5%) i wartość predykcyjną ujemną (NPV – 62,6%) nie można stwierdzić, że ogólna zdolność predykcyjna jest dobra. Z tego powodu kliniczna ocena metodą Kramera nie powinna być stosowana jako jedyne narzędzie do badań przesiewowych żółtaczki noworodkowej. 20

Badania wykazały, że metoda Kramera ma umiarkowaną dokładność diagnostyczną (76%), umiarkowaną czułość (70,5%) i dobrą swoistość (86,1%). Ponadto metoda Kramera wykazała umiarkowaną zgodność z testem TSB (κ=52,4, P≤0,01). 21

Biomarkery metabolomiczne

Najnowsze badania wskazują na potencjał biomarkerów metabolomicznych w prognozowaniu czasu trwania fototerapii u noworodków z hiperbilirubinemią. Zidentyfikowano zestaw metabolitów, które mogą dokładnie prognozować czas leczenia. Metabolity takie jak PE (22:1(13Z)/15:0), PC (18:1(9Z)/18:1(9Z)), PS (22:0/15:0), 5,6-dihydrourydyna i PE (MonoMe(11,3)/MonoMe(13,5)) mogą być wykorzystywane jako predyktory czasu trwania fototerapii w hiperbilirubinemii noworodkowej i pomagać w podejmowaniu decyzji klinicznych. 2223

Analiza ROC wykazała, że model oparty na tych metabolitach ma lepszą moc predykcyjną niż bilirubina całkowita (TSB) i bilirubina bezpośrednia (DBIL) [obszar pod krzywą (AUC): 0,806; 95% przedział ufności (CI): 0,551]. 24

Metody oparte na sztucznej inteligencji

Sztuczna inteligencja oferuje obiecujące nieinwazyjne alternatywy dla wykrywania żółtaczki noworodkowej, potencjalnie poprawiając wczesną diagnozę i postępowanie w warunkach klinicznych. 25 Opracowano systemy wykorzystujące uczenie maszynowe do wykrywania żółtaczki w czasie rzeczywistym za pomocą kamery internetowej podłączonej przez USB, bez konieczności przeprowadzania inwazyjnych testów. 26

Proponowany system ekstrahował intensywność koloru skóry z 767 zdjęć niemowląt i wykorzystywał różne modele uczenia maszynowego do testowania i walidacji. Metoda wykazała, że algorytm XGBoost zapewnił najwyższą osiągalną dokładność, wynoszącą 99,63% klasyfikacji, wśród testowanych modeli. 27

Inny model, oparty na jednowymiarowej splotowej sieci neuronowej (1DCNN), osiągnął najwyższą dokładność 96,87%, przewyższając zarówno tradycyjne metody uczenia maszynowego, jak i głębokiego uczenia. Badanie to wykazało najniższy błąd średniokwadratowy (RMSE – 1,13) i najwyższy współczynnik determinacji R² (0,91) spośród wszystkich przeanalizowanych prac, co świadczy o solidności i precyzji modelu w przewidywaniu poziomów bilirubiny. 28

Wyniki wskazują, że model łączący przestrzenie kolorów RGB i HSV osiągnął najniższy RMSE (1,13) i MAE (0,89), jednocześnie uzyskując najwyższy wynik R² (0,91), co świadczy o tym, że integracja komplementarnych przestrzeni kolorów zwiększa zarówno precyzję, jak i możliwość uogólniania. 29

Ponieważ ponad połowa noworodków rozwija żółtaczkę, a ich układy odpornościowe są słabo rozwinięte, szybkie wykrycie jest kluczowe, aby uniknąć poważnych i potencjalnie zagrażających życiu powikłań. 30 Żółtaczka pozostaje istotną przyczyną śmiertelności noworodków na całym świecie, zajmując siódme miejsce wśród głównych przyczyn zgonów w ciągu pierwszych sześciu dni życia. 31

Monitorowanie tlenku węgla w powietrzu wydychanym

Pomiar wytwarzania tlenku węgla w powietrzu wydychanym, skorygowany o stężenie tlenku węgla w otoczeniu (ETCOc), jest potencjalnie użyteczną metodą ilościowego określania hemolizy i przewidywania ryzyka rozwoju żółtaczki. 32

Badacze stwierdzili, że podwyższony poziom ETCOc we wczesnym okresie noworodkowym jest związany z późniejszą hiperbilirubinemią (HB), nawet u niemowląt bez choroby hemolitycznej. Pomiar ETCOc może być przydatny jako test przesiewowy do prognozowania niehemolitycznej HB. 33

Oznaczenie tempa produkcji bilirubiny u noworodka jest kluczowe dla oceny ryzyka rozwoju nieprzewidywalnej skrajnej hiperbilirubinemii (HB) i zapobiegania uszkodzeniom neurologicznym wywołanym przez bilirubinę (BIND). 34 Autorzy sugerują, że ponieważ niezwiązana (lub niezwiązana) bilirubina wzrasta w obecności hemolizy, istnieje związek między zwiększoną produkcją bilirubiny a całkowitą bilirubiną w organizmie, co pomaga wyjaśnić związek między żółtaczką hemolityczną a neurotoksycznością bilirubiny. 35

Aby spełnić wytyczne praktyki AAP z 2004 r., które sugerują, że niektóre niemowlęta z hemolizą wymagają leczenia przy niższych progach do rozpoczęcia fototerapii, autorzy stwierdzają, że pomiary ETCOc są obecnie najlepszą dostępną metodą identyfikacji zwiększonego obrotu hemu i produkcji bilirubiny. 36

Prognoza długoterminowa

Badania obserwacyjne

Duże prospektywne badanie kohortowe dzieci urodzonych w 35. tygodniu ciąży lub później porównało te z poziomami TSB większymi niż 13,5 mg/dl (230,9 μmol/l) z tymi, które mają poziomy mniejsze niż 13,5 mg/dl. Po dwuletniej obserwacji nie stwierdzono istotnych różnic w częstości występowania porażenia mózgowego, głuchoty, opóźnienia rozwojowego lub nieprawidłowości wzrokowych. 37

Kohorta z poziomami TSB większymi niż 19 mg/dl (325,0 μmol/l) miała zwiększone ryzyko wystąpienia zespołu deficytu uwagi (ryzyko względne = 1,9; 95% przedział ufności, 1,1 do 3,3). 38

Skuteczność screeningu i leczenia

Amerykańska Akademia Pediatrii zaleca powszechne badania przesiewowe za pomocą poziomów TSB lub przezskórnej bilirubiny (TcB) lub ukierunkowane badania przesiewowe oparte na czynnikach ryzyka. 39 Chociaż badania przesiewowe mogą identyfikować niemowlęta, których poziom TSB prawdopodobnie przekroczy 95. percentyl, U.S. Preventive Services Task Force i American Academy of Family Physicians stwierdziły niewystarczające dowody na to, że badania przesiewowe w kierunku hiperbilirubinemii są związane z poprawą wyników klinicznych. 40

Badania przesiewowe wcześniej identyfikują niemowlęta wymagające fototerapii, ale nie ma dowodów na to, że fototerapia lub transfuzja wymienna zmniejsza ryzyko encefalopatii bilirubinowej. 41

Dokładne stężenie bilirubiny związane z kernicterusem u zdrowego noworodka urodzonego w terminie jest nieprzewidywalne. 42 Chociaż ryzyko toksyczności bilirubiny jest prawdopodobnie znikome u zdrowego noworodka urodzonego w terminie bez hemolizy, lekarz powinien zacząć się niepokoić, jeśli poziom bilirubiny przekracza 25 mg/dl (428 μmol/l). 43

Znaczenie monitorowania i wczesnej interwencji

Kiedy noworodek jest wypisywany ze szpitala, lekarz lub pielęgniarka szukają objawów żółtaczki. Jeśli u noworodka występuje żółtaczka, lekarz oceni prawdopodobieństwo wystąpienia ciężkiej żółtaczki na podstawie szeregu czynników. Jeśli obecne są czynniki ryzyka wystąpienia ciężkiej żółtaczki, lekarz może zalecić wizytę kontrolną dzień lub dwa po opuszczeniu szpitala przez dziecko. 44

W zależności od szybkości wzrostu poziomu bilirubiny, ryzyko rozwoju znaczącej hiperbilirubinemii u noworodka można sklasyfikować jako niskie, pośrednie lub wysokie. Zakładając, że poziom bilirubiny będzie nadal rosnąć w tym samym tempie, lekarz może przewidzieć potencjalny dalszy postęp wzrostu i obliczyć liczbę dni, w których niemowlę może być narażone na toksyczność bilirubiny. 45

Decyzja o rozpoczęciu fototerapii opiera się na wieku noworodka i całkowitym poziomie bilirubiny w surowicy. 46 Jedynym przeciwwskazaniem do stosowania fototerapii jest hiperbilirubinemia sprzężona, jak to ma miejsce u pacjentów z cholestazą i chorobą wątroby. 47

W przypadku obecności choroby hemolitycznej, ciężkiej anemii lub szybkiego wzrostu całkowitego poziomu bilirubiny w surowicy (większego niż 1 mg/dl na godzinę w czasie krótszym niż sześć godzin), zalecanym leczeniem jest transfuzja wymienna. 48 Jeśli fototerapia nie działa, a poziomy bilirubiny u dziecka są nadal bardzo wysokie, dziecko może potrzebować specjalnego rodzaju transfuzji krwi zwanej transfuzją wymienną. 49

Większość przypadków żółtaczki ustępuje bez leczenia. 50 Niemowlęta z ciężką żółtaczką muszą być szybko leczone; w przeciwnym razie mogą rozwinąć uszkodzenie mózgu. 51 CBE (przewlekła encefalopatia bilirubinowa) nie jest powszechna, ponieważ niemowlęta zwykle są leczone zanim żółtaczka stanie się ciężka. 52

  • #1 Neonatal Jaundice: Background, Pathophysiology, Etiology
    https://emedicine.medscape.com/article/974786-overview
    Prognosis of neonatal jaundice is excellent if the patient receives treatment according to accepted guidelines. […] Brain damage due to kernicterus remains a true risk, and the apparent increased incidence of kernicterus in relatively recent years may be due to the misconception that jaundice in the healthy full-term infant is not dangerous and can be disregarded. In a retrospective survey from the United Kingdom, most infants who were subsequently diagnosed with kernicterus had been discharged home from the birth hospital, and there was a delay between recognition of jaundice and readmission, with a range of 26-102 hours. […] Of further note, the majority of these infants had an underlying diagnosis which raised the risk of pathologic neonatal jaundice. […] Kernicterus is the most important complication of neonatal jaundice. The incidence of kernicterus in North America and Europe ranges from 0.16 to 2.7 cases per 100,000 births.

    Read the well-established and mounting body of evidence recognizing the risks of unmanaged Jaundice and supporting the use of ETCOc testing with newborns. […] More than 80% of newborn infants will have some degree of jaundice. Careful monitoring of all newborn infants and the application of appropriate treatments are essential because high bilirubin concentrations can cause acute bilirubin encephalopathy and kernicterus. […] The presence of hyperbilirubinemia neurotoxicity risk factors lowers the threshold for treatment with phototherapy and the level at which care should be escalated. […] If available, measurement of end tidal carbon monoxide production, corrected for ambient carbon monoxide (ETCOc), is a potentially useful method for quantifying hemolysis. […] Researchers concluded that increased ETCOc level in the early neonatal period is associated with subsequent HB, even in infants without hemolytic disease. The ETCOc measurement may be useful as a screening test for predicting non-hemolytic HB.

    https://www.marchofdimes.org/find-support/topics/planning-baby/newborn-jaundice
    Jaundice is a common condition in newborn babies. […] Most of the time, jaundice goes away without treatment. […] Babies who have severe jaundice must be treated quickly; otherwise, they can develop brain damage. […] But if a baby has severe jaundice and doesn’t get quick treatment, it can lead to brain damage. […] These may be warning signs of dangerously high levels of bilirubin that need quick treatment to prevent a kind of brain damage caused by high bilirubin levels (acute or chronic bilirubin encephalopathy (CBE)). […] CBE isn’t common because babies usually are treated before jaundice becomes severe. […] If untreated, CBE can cause: Athetoid cerebral palsy. Babies with this condition have uncontrollable movements in the arms, legs, face and other body parts. […] Jaundice usually clears up within 2 weeks in formula-fed babies. It may last for more than 2 to 3 weeks in breastfed babies. […] If your baby’s jaundice lasts more than 3 weeks, talk to your baby’s health care provider. […] If phototherapy doesn’t work and your baby’s bilirubin levels are still very high, your baby may need a special type of blood transfusion called an exchange transfusion.
  • #4 Hyperbilirubinemia in the Term Newborn | AAFP
    https://www.aafp.org/pubs/afp/issues/2002/0215/p599.html
    If jaundice persists for more than two weeks in a formula-fed infant and more than three weeks in a breastfed infant, further evaluation is warranted. […] The decision to initiate phototherapy is based on the newborn’s age and total serum bilirubin level. […] The only contraindication to the use of phototherapy is conjugated hyperbilirubinemia, as occurs in patients with cholestasis and hepatic disease. […] In the presence of hemolytic disease, severe anemia, or a rapid rise in the total serum bilirubin level (greater than 1 mg per dL per hour in less than six hours), exchange transfusion is the recommended treatment.

    Although neonatal jaundice is common, acute bilirubin encephalopathy and kernicterus (i.e., chronic bilirubin encephalopathy) are rare. […] Severe hyperbilirubinemia (total serum bilirubin [TSB] level of more than 20 mg per dL [342.1 mol per L]) occurs in less than 2% of term infants and can lead to kernicterus (i.e., chronic bilirubin encephalopathy) and permanent neurodevelopmental delay. […] Kernicterus develops in one in 100,000 infants and manifests as athetoid cerebral palsy, auditory dysfunction, dental dysplasia, paralysis of upward gaze, and variable intellectual disability. […] One study found that less than 5% of healthy term infants with a TSB level greater than 30 mg per dL (513.1 mol per L) developed acute bilirubin encephalopathy or kernicterus. […] The American Academy of Pediatrics recommends universal screening with TSB or transcutaneous bilirubin (TcB) levels, or targeted screening based on risk factors.

    Objective: The need to recognize infants that are at high risk for developing significant jaundice is apparent in the era of routine early discharge. The aim of the present study was to prospectively determine the ability to predict severe hyperbilirubinemia in term healthy newborns (defined as total serum bilirubin of 10.0 mg/dl at day 2, 14.0 mg/dl at day 3, and 17.0 mg/dl at days 4 and 5 of life). […] Conclusion: Individual risk assessment on discharge in association with day 1 total serum bilirubin is of value in identifying infants at greater risk for neonatal jaundice.

    The study findings revealed that maternal age over 35 years, residing in urban areas [adjusted odds ratio (AOR)=2.4, 95% confidence interval (CI): 1.23, 4.82], male gender (AOR=4.3, 95% CI: 1.90, 9.74), prematurity (AOR=3.9, 95% CI: 1.88, 8.09), and ABO incompatibility (AOR=2.6, 95% CI: 1.16, 5.96) were significant determinants of neonatal jaundice. […] This study showed that cesarean delivery was 76% protective of neonatal jaundice compared with vaginal delivery (AOR=0.24, 95% CI: 0.08, 0.72). […] Hence, the probability of having a neonate with jaundice is 8.8 times higher for mothers older than 35 years of age compared to those younger than 25 years [AOR=8.8, 95%CI: (1.99, 38.78)]. Respondents who lived in urban areas were 2.4 times more likely to have neonatal jaundice than those from rural areas [AOR=2.4, 95%CI: (1.23, 4.82)]. Additionally, male neonates were found to have a 4.3 times higher likelihood of having neonatal jaundice than female neonates [AOR=4.3, 95%CI: (1.90, 9.74)].

    The study also demonstrated that premature neonates were almost four times more susceptible to jaundice compared to full-term neonates. This finding is consistent with studies conducted in India, America, Rwanda, and India. Premature newborns have immature livers, which play a vital role in bilirubin metabolism. Their immature livers may not be able to effectively process and excrete bilirubin, resulting in its accumulation and neonatal jaundice. […] Another determinant factor identified was ABO incompatibility. Neonates with ABO incompatibility were more likely to develop neonatal jaundice compared to those without. This finding is supported by a study conducted in India. ABO incompatibility can lead to immune-mediated hemolysis of the newborn’s blood due to maternal antigens, which is one of the causes of infant jaundice.

    Prognosis of neonatal jaundice is excellent if the patient receives treatment according to accepted guidelines. […] Brain damage due to kernicterus remains a true risk, and the apparent increased incidence of kernicterus in relatively recent years may be due to the misconception that jaundice in the healthy full-term infant is not dangerous and can be disregarded. In a retrospective survey from the United Kingdom, most infants who were subsequently diagnosed with kernicterus had been discharged home from the birth hospital, and there was a delay between recognition of jaundice and readmission, with a range of 26-102 hours. […] Of further note, the majority of these infants had an underlying diagnosis which raised the risk of pathologic neonatal jaundice. […] Kernicterus is the most important complication of neonatal jaundice. The incidence of kernicterus in North America and Europe ranges from 0.16 to 2.7 cases per 100,000 births.

    To prevent, diagnose, and treat neonatal jaundice effectively, efforts should primarily focus on managing ABO incompatibility and early detection of prematurity. Additionally, special attention should be given to neonates born through vaginal delivery, those with mothers over 35 years old, and those residing in urban areas, as they are at higher risk of developing newborn jaundice. Close monitoring of high-risk mother-infant pairs during the antenatal and postnatal periods, along with early intervention, is crucial for reducing the severity of neonatal jaundice in this study setting.

[…] Depending on the rate at which the bilirubin level rises, a newborn’s risk of developing significant hyperbilirubinemia can be classified as low, intermediate, or high. […] With the assumption that the bilirubin level will continue to rise at the same rate, the physician can predict the potential further progression of the rise and calculate the number of days that the infant may be at risk for bilirubin toxicity.

    Your doctor will likely diagnose infant jaundice on the basis of your baby’s appearance. However, it’s still necessary to measure the level of bilirubin in your baby’s blood. The level of bilirubin (severity of jaundice) will determine the course of treatment. […] When your baby is discharged from the hospital, your doctor or nurse will look for jaundice. If your baby has jaundice, your doctor will assess the likelihood of severe jaundice based on a number of factors: […] If risk factors for severe jaundice are present, your doctor may recommend a follow-up visit a day or two after the baby leaves the hospital. […] Is the jaundice severe? […] Does my baby need to begin treatment for jaundice? […] Will I need to readmit my baby to the hospital? […] Will my baby need to go back into the hospital?

    If jaundice persists for more than two weeks in a formula-fed infant and more than three weeks in a breastfed infant, further evaluation is warranted. […] The decision to initiate phototherapy is based on the newborn’s age and total serum bilirubin level. […] The only contraindication to the use of phototherapy is conjugated hyperbilirubinemia, as occurs in patients with cholestasis and hepatic disease. […] In the presence of hemolytic disease, severe anemia, or a rapid rise in the total serum bilirubin level (greater than 1 mg per dL per hour in less than six hours), exchange transfusion is the recommended treatment.

    Jaundice is a common condition in newborn babies. […] Most of the time, jaundice goes away without treatment. […] Babies who have severe jaundice must be treated quickly; otherwise, they can develop brain damage. […] But if a baby has severe jaundice and doesn’t get quick treatment, it can lead to brain damage. […] These may be warning signs of dangerously high levels of bilirubin that need quick treatment to prevent a kind of brain damage caused by high bilirubin levels (acute or chronic bilirubin encephalopathy (CBE)). […] CBE isn’t common because babies usually are treated before jaundice becomes severe. […] If untreated, CBE can cause: Athetoid cerebral palsy. Babies with this condition have uncontrollable movements in the arms, legs, face and other body parts. […] Jaundice usually clears up within 2 weeks in formula-fed babies. It may last for more than 2 to 3 weeks in breastfed babies. […] If your baby’s jaundice lasts more than 3 weeks, talk to your baby’s health care provider. […] If phototherapy doesn’t work and your baby’s bilirubin levels are still very high, your baby may need a special type of blood transfusion called an exchange transfusion.
