ABSTRACT

RESUMO Objetivo Analisar a hiperbilirrubinemia como indicador para a realização do protocolo de risco na triagem auditiva neonatal (TAN) e no monitoramento auditivo em neonatos a termo e prematuros. Método Trata-se de um estudo observacional, transversal e retrospectivo. Foram incluídas 554 crianças nascidas em uma maternidade pública, subdivididas em dois grupos: (G1) com 373 recém-nascidos a termo; (G2) com 181 neonatos prematuros. Os dados foram coletados nos prontuários dos participantes, a fim de se obter informações referentes ao resultado da TAN realizada por meio do registro do Potencial Evocado Auditivo de Tronco Encefálico, às condições de nascimento, características clínicas, intervenções realizadas, resultados do primeiro exame de bilirrubina total (BT) e bilirrubina indireta (BI) e do pico de BT e BI. Realizou-se análise estatística descritiva e inferencial dos dados, com adoção do nível de significância de 5%. Resultados No teste da TAN, foram observadas taxas de encaminhamento para reteste inferiores no G1 em relação ao G2. Não houve diferença entre os grupos quanto à ocorrência do tipo de parto, sexo, presença de incompatibilidade sanguínea Rh e ABO, deficiência de enzima G6PD e realização de fototerapia. Em relação aos níveis de BT e BI no primeiro exame e no momento do pico, não houve diferenças entre os neonatos com resultado "passa" e "falha" na TAN-teste nos dois grupos. Conclusão Os níveis de bilirrubina no período neonatal abaixo dos valores recomendados para indicação de exsanguineotransfusão não estão diretamente relacionados ao resultado "falha" na TAN em neonatos a termo e prematuros.


ABSTRACT Purpose To analyze hyperbilirubinemia as an indicator for the definition of risk protocol in newborn hearing screening (NHS) and in auditory monitoring in full-term and preterm neonates. Methods This is an observational, cross-sectional and retrospective study. A total of 554 children born in a public maternity hospital were included and divided into two groups: (G1) with 373 full-terms neonates; (G2) with 181 preterm neonates. Data were collected from the participant's medical records to obtain information regarding the result of the NHS, performed by recording the automated auditory brainstem response (AABR), birth conditions, clinical characteristics, interventions performed, and results of the first test of total bilirubin (TB) and indirect bilirubin (IB) as well as the peak of TB and IB. A descriptive statistical analysis of the results was performed, and the level of significance adopted was 5%. Results On the NHS test, quotes of retest referral rates were smaller in G1 when compared to G2. There was no significant difference between the groups regarding type of delivery, gender, presence of Rh and ABO incompatibility, G6PD enzyme deficiency, and performance of phototherapy. TB and IB levels at the first exam and at peak time did not differ between neonates with "pass" and "fail" results on the NHS test in both groups. Conclusion Bilirubin levels in the neonatal period below the recommended values for indication of exchange transfusion are not directly related to the "fail" result on the NHS tests in term and preterm neonates.

ABSTRACT

El shunt portosistémico congénito es una anomalía vascular venosa que comunica circulación portal y sistémica, por la que se deriva el flujo sanguíneo, salteando el paso hepático. Es una entidad poco frecuente, cuya incidencia varía entre 1/30 000 y 1/50 000 recién nacidos. Puede cursar de forma asintomática o presentarse con complicaciones en la edad pediátrica o, menos frecuente, en la edad neonatal. Ante el diagnóstico, se deberá definir la necesidad de intervención quirúrgica o intravascular para el cierre. Esta decisión depende de las características anatómicas de la malformación, de las manifestaciones clínicas y complicaciones presentes. Se presenta el caso de un paciente de un mes de vida derivado a nuestro centro para estudio de hepatitis colestásica neonatal, con diagnóstico de shunt portosistémico extrahepático. Se realizó cierre intravascular de la lesión con mejoría significativa posterior.


Congenital portosystemic shunt is a venous vascular abnormality that connects portal and systemic circulation, resulting in diversion of the blood flow, bypassing the hepatic passage. It is a rare malformation; its incidence varies from 1:30 000 to 1:50 000 newborns. It may be asymptomatic or present with complications in the pediatric age or, less frequently, in the neonatal age. Upon diagnosis, the need for a surgical or an intravascular intervention for closure should be defined. This decision depends on the malformation anatomical characteristics, clinical manifestations, and complications. We present the case of a 1-month-old patient referred to our center for the study of neonatal cholestatic hepatitis, with a diagnosis of extrahepatic portosystemic shunt. Intravascular closure of the defect was performed with significant subsequent improvement.

ABSTRACT

Objetivo: identificar mediante análise macroscópica e ra-diográfica as alterações estruturais em tecidos dentários afetados pela hiperbilirrubinemia, normalmente constatada a partir do sinal clínico de icterícia e provoca o desenvolvi-mento de pigmentos intrínsecos esverdeados nas estruturas dentárias. Materiais e Métodos: a amostra foi composta por 31 dentes decíduos dividida em grupo controle (n= 7) e grupo experimental (n= 24). As análises macroscópicas foram efetuadas por meio de fotografias individuais padroniza-das e as radiográficas obtidas com aquisições de imagem a 9 mA, 70 kVp, distância de 8cm, exposição 0,4 segundos e com XDR Sensor®. As imagens foram convertidas pelo software XDR Brasil 3.1.6 e padronizadas pelo programa GIMP 2.10.22. Os dados da média simples do histograma foram analisados pelo teste T-Student e Mann-Whitney (p<0,05). Resultados: demonstraram a maior intensidade de pigmentação em região cervical da raiz, com diferença de densidade radiográfica estaticamente significante na porção radicular entre os grupos experimental e controle (p=0,043). Na análise da densidade radiográfica da estrutura radicular do grupo experimental houve diferença estatica-mente significante (p=0,016) entre os terços cervical e apical. Discussão: Os dados evidenciaram que dentes pigmentados pela hiperbilirrubinemia não possuem alterações na densidade mineral nos terços coronários. Conclusão: Dentes com pigmentação esverdeada bilirrubina possuem diferenças na densidade radiográfica so-mente na região radicular.


Aim: is to identify, through macroscopic and radio-graphic analysis, structural changes in dental tissues affected by hyperbilirubinemia, usually seen from the clinical sign of icterus and causes the development of intrinsic greenish pigments in dental structure. Materials and Methods: The sample consisted of 31 primary teeth divided into a control group (n=7) and an experimental group (n=24). Macroscopic analyzes were performed using standardized individual photographs and radiographic ones obtained by image acquisition at 9 mA, 70 kVp, 8cm distance, 0.4 seconds exposure and with XDR Sensor®. The images were converted by XDR Brasil 3.1.6 software and standardized by GIMP 2.10.22 software. The Histogram's simple mean data were analyzed by T-Student and Mann-Whitney tests (p<0.05). Results: showed intensity of pigmentation in the cervical region of the root, with a statistically significant difference in the root portion between the experimental and control groups (p=0.043. In the analysis of radiographic density of the root structure of the experimental group, there was a statistically significant difference (p= 0.016) between the cervical and apical thirds. Discussion: The data showed that teeth pigmented by hyperbilirubinemia do not have changes in mineral density in the coronary thirds. Conclusion: Greenish pigments teeth have differences in radiographic density only in the root structure.

ABSTRACT

Resumen | Hay pocos reportes de enfermedad hemolítica del feto y del recién nacido causada por aloanticuerpos contra el sistema de antígenos MNS, especialmente, porque los anticuerpos que se generan contra estos antígenos son del tipo IgM, los cuales tienen reactividad a temperaturas inferiores a los 37 °C, y, por lo tanto, no son de importancia clínica. A pesar de ello, se han reportado casos con presencia de anticuerpos anti-M de tipo IgG causantes de la enfermedad hemolítica del recién nacido e, incluso, casos de muerte intrauterina por incompatibilidad materno-fetal en el sistema MNS. El proceso hemolítico se asemeja al causado por los anticuerpos anti-Kell, con anemia progresiva por supresión hematopoyética que induce la destrucción de precursores hematopoyéticos en la médula ósea y ausencia de reticulocitos en la periferia. Se reporta el caso de una mujer con 38,5 semanas de gestación, que presentó discrepancia en la hemoclasificación directa y en la inversa. Como resultado, el recién nacido fue positivo en la prueba de Coombs directa sin que existiera incompatibilidad ABO con la madre. La correlación de estos resultados llevó a la detección de un anticuerpo anti-M en el suero materno. El diagnóstico definitivo fue posible gracias a la discrepancia en la hemoclasificación de la sangre materna. A pesar de que los anticuerpos anti-M usualmente no desempeñan un papel importante en la enfermedad hemolítica perinatal, este caso resalta la importancia de determinar la presencia de diferentes anticuerpos que pueden ser de vital interés a la hora de prevenir resultados graves asociados con dicha condición. Además, abre la puerta a nuevas recomendaciones relacionadas con la tamización y el tratamiento temprano de la hemólisis en los recién nacidos.


Abstract | There are few case reports of hemolytic disease in fetuses and newborns (HDFN) caused by alloantibodies against the MNS blood group system. The reason for this dearth is that antibodies toward these antigens are usually IgM, which not only cannot cross the placental circulation but also react at temperatures below 37°C. They are, therefore, of minimal clinical importance. Nevertheless, cases have been reported in which the presence of anti-M IgG antibodies caused severe HDFN and even intrauterine death in the presence of maternal-fetal MNS incompatibility indicating that they could have a high clinical impact. The hemolytic pattern observed in these cases is similar to that caused by anti-Kell antibodies. Progressive anemia is mediated and developed through hematopoietic suppression inducing the destruction of bone marrow precursor cells with the resulting absence of reticulocytes in peripheral blood. This occurred in the case of a woman at 38.5 weeks of gestation who showed a discrepancy between direct and reverse blood type determination. A direct Coombs test was performed on the newborn's blood, which was positive in the absence of maternal-fetal ABO incompatibility. Further tests were performed and anti-M antibodies were found in the maternal serum screening. Our final diagnosis was largely due to discrepancy issues in maternal blood. Although anti-M antibodies do not usually play a significant role in HDFN, this case stresses the importance of identifying the presence of antibodies that can be crucial in preventing HDFN and lead to new recommendations for the screening and prompt treatment of hemolysis in newborns.

ABSTRACT

Definida como una concentración sérica de bilirrubina, la hiperbilirrubinemia es una condición rara y puede ser causada por cualquier factor que eleve la carga de bilirrubina a ser metabolizada por el hígado. Así, la bilirrubina se distribuye por los tejidos corporales y se acumula en los tejidos duros, incluso, en los dientes primarios. El objetivo de este trabajo es relatar un caso clínico sobre la repercusión severa de la hiperbilirrubinemia en dientes primarios y sus manifestaciones bucales en la primera infancia, como dientes verdosos. Paciente del sexo masculino, 3 años y 8 meses, estuvo en clínica odontológica para evaluación de "manchas verdes en los dientes". En su historia médica se observó que nació prematuro y tuvo complicaciones posparto que evolucionaron para sepsis Dientes primarios verdes por hiperbilirrubinemiaIvana Aguiar Raposo,1.....

Revista de Odontopediatría Latinoamericana¹ São Leopoldo Mandic Campinas, Sao Paulo, Brasil.2 Universidade Paulista. 3 Universidade Federal de Pernambuco.4 Universidade Federal de Santa Maria.5 Universidade São Paulo - USP.Casos ClínicosDOI: 10.47990/alop.v11i2.304y, como consecuencia del uso de varios medicamentos, desarrolló un cuadro de hiperbilirrubinemia. El examen clínico dental constató la presencia de manchas verdes en los 20 dientes primarios, ausencia de lesión de caries, encías sanas y buena condición de higiene bucal. Se concluye que los altos niveles de bilirrubina desarrollados por el niño prematuro asociados a septicemia pueden llevar a la pigmentación verde (coloración intrínseca) en los dientes primarios durante el periodo de calcificación de los mismos (odontogénesis), incluso a la afectación de los dientes permanentes. Por eso, es relevante el conocimiento de la historia médica del niño desde el nacimiento para el establecimiento del diagnóstico y pronóstico de las alteraciones dentales


Defined as a serum bilirubin concentration, hyperbilirubinemia is a rare condition and can be caused by any factor that raises the bilirubin load to be metabolized by the liver. Thus, bilirubin is distributed throughout the body's tissues and accumulates in hard tissues, including primary teeth. The aim of this work is to report a clinical case about the severe repercussion of hyperbilirubinemia in primary teeth, and its early childhood manifestations, such as greenish teeth. A male patient, 3 years and 8 months old, attended the dental clinic for evaluation of "green spots on teeth". Medical history revealed that the child had premature birth and postpartum complications that evolved into sepsis, and due to the use of several drugs, developed hyperbilirubinemia. The dental clinical examination showed the presence of green spots on all 20 deciduous teeth, absence of carious lesions, healthy gums and good oral hygiene conditions. We conclude

ABSTRACT

OBJETIVO: determinar el perfil clínico de pacientes con diabetes gestacional (DG) y la incidencia de las complicaciones neonatales. MÉTODOS: estudio descriptivo de una cohorte retrospectiva de gestantes con DG según criterios HAPO/ (IADPSG) International Association of Diabetes and Pregnancy Study Groups y Carpenter-Coustan y sus hijos, en un servicio de alta complejidad obstétrica de Medellín, Colombia entre 2012-2015. Se presentan medidas descriptivas de características maternas y neonatales e incidencia de las complicaciones neonatales. RESULTADOS: se incluyeron 197 maternas y 203 neonatos; 90,5 % maternas tenían sobrepeso u obesidad; la comorbilidad más frecuente fue el trastorno hipertensivo asociado al embarazo en 22,8 %. El manejo de la DG fue 59,3% nutricional exclusivo, 37,1% nutricional más insulina y 3.6% nutricional más metformina. La media de edad gestacional al parto fue 37 sem y 3 días; la DG fue la indicación más frecuente de inducción del parto en 76 % (38/50); 56,4 %, fueron partos vaginales y el 34,6% fueron cesáreas indicadas por DG. Un 11,3 % de los recién nacidos fueron grandes para la edad gestacional (P >90) y se encontraron 2 recién nacidos con peso > 4000 gr. La incidencia de al menos una complicación neonatal fue 27,6 %, 16,7 % presentaron hiperbilirrubinemia, 9,9 % síndrome de dificultad respiratoria (SDR), 3.0% hipoglicemia, 10.8% otras complicaciones y 12,3 % ingresaron a la unidad de cuidados intensivos neonatales. CONCLUSIONES: la DG es una indicación frecuente de inducción del parto y de indicación de cesárea. Las complicaciones neonatales ocurren en uno de cuatro recién nacidos, aunque observamos una baja incidencia de grandes para la edad gestacional (recién nacidos con peso > percentil 90), hubo 2 otras morbilidades neonatales relacionados con el diagnóstico materno como hiperbilirrubinemia y SDR.


AIM: To determine the clinical profile pregnant women with gestational diabetes and incidence of the neonatal complications. METHODS: Descriptive analysis of a retrospective cohort of pregnant women with gestational diabetes (GD) according to HAPO and Carpenter-Coustan criteria and their children, under a high complexity obstetric service in Medellin, Colombia between 2012-2015. Descriptive measures of maternal and neonatal characteristics and incidence of neonatal complications are presented. RESULTS: The study included 197 pregnant women and 203 neonates: 90.5 % of pregnancies were overweight or obese; the most frequent comorbidity was the hypertensive disorder associated with pregnancy in 22.8 %. The management of the DG was 99.0% nutritional, 37.1% insulin and 3.6 % metformin. The average gestational age at delivery was 37 weeks and 3 days; DG was the most frequent indication of induction of labor in 76 % (38/50); 56.4% were vaginal deliveries and 34.6 % were DG related caesarean sections, 11.3 % of newborns were large for gestational age (P > 90) and two newborns weighing > 4000 gr. The incidence of at least one neonatal complication was 27.6 %, 16.7 % had hyperbilirubinemia, 9.9 % respiratory distress syndrome (RDS), 3.0 % hypoglycemia, 10.8 % other complications and 12.3 % were admitted to the neonatal intensive care unit. CONCLUSIONS: DG is a frequent indication of induction of labor and indication of caesarean section. Neonatal complications occur in one of four newborns, although we observed a low incidence of macrosomia, there were other neonatal morbidities related to maternal diagnosis such as hyperbilirubinemia and RDS.

ABSTRACT

ABSTRACT Hyperthyroidism can induce elevation in several liver function tests including aminotransferases, alkaline phosphatases and, less frequently, serum bilirubin. These alterations are usually mild and asymptomatic. We report a 26 year-old male presenting with palpitations, progressive jaundice, choluria and generalized itching. Laboratory tests were compatible with hyperthyroidism and a mild elevation of bilirubin, alkaline phosphatases and gamma glutamyl transpeptidase. A liver biopsy showed portal hepatitis with canalicular cholestasis. The patient was treated temporarily with glucocorticoids, cholestyramine and betablockade. Thereafter, he was treated with radioactive iodine, after which serum bilirubin decreased steadily until normalization in ten weeks.


El hipertiroidismo puede producir elevación de aminotransferasas, fosfatasas alcalinas y, menos frecuentemente, de bilirrubina sérica. Habitualmente, estas alteraciones son leves y asintomáticas. Reportamos un hombre de 26 años con hipertiroidismo secundario a enfermedad de Basedow-Graves, que debutó con un cuadro colestásico, inicialmente estudiado por sospecha de patología hepática autoinmune que incluyó biopsia hepática. Posteriormente, se diagnosticó hipertiroidismo que fue tratado con glucocorticoides, colestiramina y beta bloqueo como puente a terapia definitiva con radioyodo. La evolución mostró disminución progresiva hasta la normalización de bilirrubina sérica.

ABSTRACT

Introducción: Se ha establecido que la fototerapia con tecnología LED es más efectiva que la fototerapia convencional para el tratamiento de hiperbilirrubinemia neonatal al reducir el número de horas de tratamiento requerido en los recién nacidos a término y pretérmino. El objetivo del presente estudio fue realizar un estudio clínico aleatorizado con tres tipos de lámparas incluida una de prototipo. Métodos: En el presente estudio clínico con un diseño paralelo de tres grupos, participaron recién nacidos con necesidad de tratamiento por hiperbilirrubinemia, ingresados en la Unidad de Neonatología del Hospital Homero Castanier Crespo en Azogues-Ecuador. Fueron distribuidos en 3 grupos: Grupo 1 (G1) Fototerapia con lámpara fluorescente, Grupo 2 (G2) fototerapia LED comercializada (Medix®, Mediled®), Grupo 3 (G3) con Fototerapia LED de prototipo. Se mide la concentración de bilirrubinas y la diferencia de medias de su reducción en cada grupo para demostrar no inferioridad. Resultados: El peso en G1 (n=30) fue 3050 ±134 gr, en G2 (n=30): 3200 ±186; G3 (n=30): 3034 ±234 (P=0.70). La edad gestacional en G1: 39 ±1 semanas, en G2 39.1±1.1, en G3 39 ±1.1 (P=0.80). Bilirrubina en G1: 15.8 ±6.2, en G2: 14. 93 ±5.9 y en G3: 15.62 ±5.9 mg/dl. (P=0.60). Las diferencias de bilirrubina (Delta 1) pre-tratamiento y a las 24 horas de tratamiento fueron -2.4 en G1, -2.4 en G2 y -2.25 mg/dl en G3 (P=0.60). Delta 2 a las 48 horas: -4.5 en G1, -4.26 en G2 y -4.42 mg/dl en G3 (P=0.62). Conclusión: los tres tratamientos demostraron No inferioridad en el tratamiento de hiperbilirrubinemia neonatal


Introduction: It has been established that phototherapy with LED technology is more effective than conventional phototherapy for the treatment of neonatal hyperbilirubinemia by reducing the number of hours of treatment required in term and preterm newborns. The objective of the present study was to carry out a randomized clinical study with three types of lamps, including a prototype. Methods: In the present clinical study with a parallel design of three groups, newborns with need of treatment for hyperbilirubinemia, admitted to the Neonatology Unit of the Homero Castanier Crespo Hospital in Azogues-Ecuador, participated. They were divided into 3 groups: Group 1 (G1) Phototherapy with fluorescent lamp, Group 2 (G2) commercialized LED phototherapy (Medix®, Mediled®), Group 3 (G3) with prototype LED phototherapy. The bilirubin concentration and the mean difference of its reduction in each group are measured to demonstrate non-inferiority. Results: The weight in G1 (n = 30) was 3050 ± 134 gr, in G2 (n = 30): 3200 ± 186; G3 (n = 30): 3034 ± 234 (P = 0.70). Gestational age in G1: 39 ± 1 weeks, in G2 39.1 ± 1.1, in G3 39 ± 1.1 (P = 0.80). Bilirubin in G1: 15.8 ± 6.2, in G2: 14. 93 ± 5.9 and in G3: 15.62 ± 5.9 mg / dl. (P = 0.60). The differences in bilirubin (Delta 1) pre-treatment and at 24 hours of treatment were -2.4 in G1, -2.4 in G2 and -2.25 mg / dl in G3 (P = 0.60). Delta 2 at 48 hours: -4.5 in G1, -4.26 in G2 and -4.42 mg / dl in G3 (P = 0.62). Conclusion: the three treatments demonstrated non-inferiority in the treatment of neonatal hyperbilirubinemia

ABSTRACT

La presencia de ictericia en la etapa neonatal puede responder a diversas causas, desde situaciones fisiológicas hasta enfermedades graves. En los neonatos de término que persisten ictéricos más allá de los 14 días de vida, debe determinarse si la hiperbilirrubinemia es no conjugada o conjugada para establecer, a la brevedad, el plan de estudios etiológicos y la terapéutica correspondiente. La hiperbilirrubinemia conjugada (colestasis) refleja una disfunción hepática en la mayoría de los casos, cuyas consecuencias son alteraciones del flujo biliar secundarias a anormalidades estructurales o moleculares del hígado y/o del tracto biliar.Durante la última década, los nuevos estudios moleculares revolucionaron el abordaje de los pacientes colestáticos, lo que permitió el diagnóstico de diversas entidades genéticas. La etiología de la hiperbilirrubinemia del primer trimestre debe determinarse con urgencia, ya que, en muchos casos, el tratamiento instituido de modo precoz puede modificar sustancialmente la evolución de la enfermedad o salvar la vida del paciente.


Neonatal jaundice may be due to different causes, ranging from physiological conditions to severe diseases. In term neonates with persistent jaundice beyond 14 days of life, it should be determined whether hyperbilirubinemia is unconjugated or conjugated, in order to study the etiology and start early treatment. In the majority of cases, conjugated hyperbilirubinemia (cholestasis) is a sign of liver dysfunction possibly associated with alterations in the bile flow secondary to structural or molecular abnormalities of the liver and/or the biliary tract. Over the past decade, new molecular studies have revolutionized the approach of cholestatic patients, leading to the identification of different genetic entities. It is important to determine the etilogy of neonatal hyperbilirubinemia since in many cases early treatment will substantially improve morbidity and mortality.

ABSTRACT

SUMMARY The increase in bilirubin levels in newborns can cause toxic effects on the auditory system, which can lead to hearing loss. This review aimed to verify the impact of hyperbilirubinemia in the hearing of newborns, relating audiological findings to serum levels of bilirubin. A literature review was conducted during October 2017, using the terms "hyperbilirubinemia", "jaundice", "infant", "newborn" and "hearing loss", on databases CAPES journals, MEDLINE and BIREME (SciELO, BBO). 827 studies were identified and 59 were selected for full-text reading, resulting in the selection of seven articles that met the inclusion criteria and were considered relevant to the sample of this study. All the reviewed studies performed brainstem auditory evoked potential as the main test for audiological evaluation. Changes in the audiological findings of neonates with hyperbilirubinemia were observed in all studies. There was no consensus on the serum bilirubin levels that may cause auditory changes; however, the relationship between hearing disorders and blood levels of bilirubin was positive. We identify the need to establish reference values for bilirubin levels considered critical for the occurrence of hearing disorders as well as the audiological follow-up of neonates with hyperbilirubinemia.


RESUMO O aumento nos níveis de bilirrubina no neonato pode provocar efeitos tóxicos no sistema auditivo, podendo levar à perda auditiva. O objetivo desta revisão foi verificar o impacto da hiperbilirrubinemia na audição de recém-nascidos, relacionando os achados audiológicos aos níveis séricos de bilirrubina. Realizou-se uma revisão sistemática de literatura durante o mês de outubro de 2017, utilizando-se os termos hyperbilirubinemia, jaundice, infant, newborn e hearing loss, nas bases de dados periódicos Capes, Medline e Bireme (SciELO, BBO). Foram identificados 827 estudos, dentre os quais 59 foram selecionados para leitura do texto na íntegra, resultando na seleção de sete artigos que atendiam aos critérios de inclusão e foram considerados relevantes para a amostra deste trabalho. Em todas as pesquisas revisadas, o potencial evocado auditivo de tronco encefálico foi o principal exame audiológico realizado. Em todos os estudos foram observadas alterações nos resultados audiológicos de neonatos com hiperbilirrubinemia. Não houve consenso quanto aos níveis séricos de bilirrubina que podem causar alterações auditivas, porém, a relação entre as alterações audiológicas e os níveis sanguíneos de bilirrubina foi positiva. Percebeu-se a necessidade de estabelecer valores de referência para os níveis de bilirrubina considerados críticos para a ocorrência de alterações audiológicas, assim como de acompanhamento audiológico dos neonatos com hiperbilirrubinemia.

ABSTRACT

INTRODUCCIÓN: La hiperbilirrubinemia es altamente prevalente en los recién nacidos, con riesgo de compromiso neurológico con bilirrubinemias mayor a 20-25 mg/dl. Esta progresión es prevenible con detección y tratamiento precoz. OBJETIVO: Describir incidencia y factores asociados en pacientes hospitalizados con hiperbilirrubinemia mayor de 20 mg/dl, y el seguimiento de casos sintomáticos durante hospitalización. PACIENTES Y MÉTODO: Estudio retrospectivo de pacientes con hiperbilirru- binemia severa, entre el 2013 y 2016. Se evaluaron factores de riesgo, estratificándose por nivel de bilirrubina, edad de ingreso y edad gestacional. Se compararon los datos con test exacto de Fisher, chi cuadrado y riesgo relativo (RR) en una base de excel, con un error alfa de un p<0.05. Los datos fueron obtenidos a través de la epicrisis electrónica y de la ficha de control a nivel secundarios. RESULTADOS: Durante el periodo, de 25.288 recién nacidos vivos (RNV), 593 se hospitalizaron por hiperbilirrubinemia mayor de 20 mg/dl, 1 por cada 42 RNV; y 59 con bilirrubinemia mayor a 25 mg/dl, 1 por cada 428 RNV. La hiperbilirrubinemia fue más frecuente en varones, con RR 1,22 (IC 95% 1,04-1,44) y en pretérminos tardíos, con un RR 2,39 (IC 95% 1,96-2,93) comparado con RN de término. En los ingresados con más de 4 días, el principal factor asociado fue la baja de peso excesiva, y en los primeros 3 días, la incompatibilidad de grupo clásico. Tres de 10 pacientes con encefalopatía aguda, persistieron con compromiso neurológico, lo que significa 11,8 por 100.000 nacidos vivos. CONCLUSIONES: Los principales factores de riesgo para desarrollar hiperbilirrubinemia severa fueron prematurez, baja de peso excesiva, incompatibilidad de grupo clásico y sexo masculino. Estos hallazgos permiten focalizar la atención en grupos de riesgo y disminuir la probabilidad de daño neurológico.


INTRODUCTION: Hyperbilirubinemia is highly prevalent in newborns, with risk of neurological invol vement with bilirubinemia higher than 20 to 25 mg/dl. This progression is preventable with early de tection and treatment. OBJECTIVE: To describe the incidence and associated factors in hospitalized pa tients with hyperbilirubinemia higher than 20 mg/dl, and the follow-up of symptomatic cases during hospitalization. OATIENTS Y METHOD: Retrospective study of patients with severe hyperbilirubine mia, between 2013 and 2016. Risk factors were evaluated, stratifying by bilirubin level, admission age, and gestational age. The data were compared with Fisher's exact test, chi-square test, and relative risk (RR) in an Excel database, with an alpha error of p <0.05. The data were obtained from the electronic discharge summary and the medical record of secondary level follow-up. RESULTS: During the studied period, out of 25,288 live newborns (NB), 593 were hospitalized due to hyperbilirubinemia higher than 20 mg/dl, one per each 42 live NB; and 59 with bilirubinemia higher than 25 mg/dl, one per each 428 live NB. Hyperbilirubinemia was more frequent in males, with RR 1.22 (95% CI 1.04-1.44), and in late preterm newborns, with RR 2.39 (95% CI 1.96-2.93) compared with term NB. In those admitted with more than four days, the main associated factor was excessive weight loss, whereas in the first three days was classic group incompatibility. Three of ten cases with acute encephalopathy persisted with neurological involvement, which means 11.8 per 100,000 live births. CONCLUSIONS: The main risk factors for developing severe hyperbilirubinemia were prematurity, excessive weight loss, classic group incompatibility, and male sex. These findings allow to focus attention on risk groups and decrease the probability of neurological damage.

ABSTRACT

Introducción. El embarazo adolescente en Perú es un problema de salud pública que presenta alta prevalencia en regiones como Ica, y se considera como una causa de ciertos desenlaces adversos a la salud del recién nacido como bajo peso e hiperbilirrubinemia. Métodos. Se diseñó una cohorte retrospectiva constituida por gestantes adolescentes entre 13 y 19 años, las cuales fueron divididas en dos grupos: grupo 1 (<18 años de edad) y grupo 2 (≥18 años de edad). Resultados. Se evaluaron 481 gestantes adolescentes, de las cuales el grupo 1 representó el 65,3%. Se encontró recién nacidos con bajo peso e hiperbilirrubinemia en el 3,3% y 18.9%, respectivamente. El análisis bivariado evidenció diferencias significativas (p<0,001) entre la mediana de edad gestacional entre madres con recién nacidos con peso normal y bajo peso, así como en relación al tipo de parto (cesárea y normal). En cuanto a la hiperbilirrubinemia, tanto el análisis bivariado como el multivariado no evidenciaron diferencias significativas. La regresión de Cox permitió evidenciar que las gestantes adolescentes del grupo 1 tuvieron casi 8 veces más riesgo (HR: 7,95, p<0,05) de tener un recién nacido con bajo peso en comparación a las gestantes del grupo 2. Conclusión. El embarazo adolescente está asociado al bajo peso al nacer, más no a la hiperbilirrubinemia neonatal.


Introduction. Adolescent pregnancy in Peru is a public health problem that has high prevalence in regions such as Ica, and is considered as a cause of certain adverse outcomes to the health of the newborn as low weight and hyperbilirubinemia. Methods. A retrospective cohort was designed consisting of adolescent pregnant women between 13 and 19 years of age, which were divided into two groups: group 1 (<18 years of age) and group 2 (≥18 years of age). Results. A total of 481 adolescent pregnant women were evaluated, of which group 1 represented 65,3%. Newborns with low weight and hyperbilirubinemia were found in 3,3% and 18,9%, respectively. The bivariate analysis showed significant differences (p<0,001) between the median gestational age among mothers with newborns with normal weight and low weight, as well as in relation to the type of delivery (cesarean and normal). Regarding hyperbilirubinemia, both bivariate and multivariate analyzes showed no significant differences. The Cox regression showed that adolescent pregnant women in group 1 had almost 8 times more risk (HR: 7,95, p<0,05) of having a newborn with low weight compared to the pregnant women in group 2. Conclusion. Adolescent pregnancy is associated with low birth weight, but not with neonatal hyperbilirubinemia.

ABSTRACT

Resumen La bilirrubina es el producto final de la degradación del grupo hem. La bilirrubina no conjugada (BNC) se forma en las células retículoendoteliales, transportada al hígado, donde es conjugada a glucurónidos y secretada a los canalículos. La BNC se solubiliza en el suero por medio de su fuerte unión con la albúmina. La unión bilirrubina-albúmina es una función de las concentraciones de la albúmina y de la bilirrubina y de la afinidad de unión por la bilirrubina. La fracción de bilirrubina no unida o bilirrubina libre plasmática (Bf) se incrementa significativamente conforme el nivel de bilirrubina sérica total (BST) alcanza la capacidad de unión de la albúmina. La Bf es considerada un mejor indicador de neurotoxicidad que la BST, a causa de que solamente la bilirrubina libre puede cruzar la barrera hematoencefálica. En la práctica médica la bilirrubina es un marcador de disfunción hepática, colestasis o enfermedad hemolítica. Una variedad de factores limita la sensibilidad y la especificidad de la medición de la bilirrubina para detectar anormalidades: lipemia, hemólisis, exposición a la luz visible y el estado de ayuno. La hiperbilirrubinemia puede ser clasificada como prehepática, hepática y poshepática, y esto brinda un marco útil para identificar la causa subyacente. Además, hay bilirrubina conjugada y no conjugada. La hiperbilirrubinemia y la ictericia neonatales se presentan en casi todos los recién nacidos y puede ser benigna si su progresión a hiperbilirrubinemia es reconocida, monitoreada y prevenida o tratada en una manera oportuna.


Abstract Bilirubin is the end product of heme breakdown. Unconjugated bilirubin (UB) is formed in reticuloendothelial cells, transported to the liver where it is conjugated to glucuronides, and then secreted into the canaliculi. UB is solubilized in serum via very tight linkage to albumin. Bilirubin-albumin binding is a function of the concentration of bilirubin and albumin and the binding affinity for bilirubin. The fraction of unbound bilirubin or plasma free bilirubin (Bf) increases significantly as the total serum bilirubin (TSB) level approaches the binding capacity of albumin. Bf is thought to be better indicator of neurotoxicity than TSB, because only plasma free bilirubin can cross the blood-brain barrier. In medical practice bilirubin is a marker of liver dysfunction, cholestasis or hemolytic disease. A variety of factors limit both the sensitivity and the specificity of bilirubin measurement to detect the abnormalities: lipemia, hemolysis, exposure of visible light and fasting state. Hyperbilirubinemia can be categorised as prehepatic, hepatic or poshepatic, and this provides a useful framework for identifying the underlying cause. In addition, there are conjugated and unconjugated bilirubin. Neonatal hyperbilirubinemia and jaundice occur in almost all newborns and may be benign if its progression to extreme hyperbilirubinemia is recognized, monitored and prevented or managed in a timely manner.

ABSTRACT

Introducción: Las pautas para prevención y tratamiento de hiperbilirrubinemia neonatal recomiendan medición de bilirrubina sérica total (BST) o bilirrubina transcutánea (BTc) para determinar el grado de ictericia antes del alta del recién nacido (RN); ésta última no invasiva, proporciona información instantánea y de calidad superior a la evaluación clínica. A pesar de ello aún no ha sido aplicada en forma sistemática en los hospitales de Paraguay. Objetivo: evaluar la aplicación en nuestro medio de la medición de bilirrubinemia transcutánea antes del alta correlancionando con la bilirrubina sérica. Materiales y Métodos: Estudio observacional, descriptivo con componente analítico, de corte transversal. Fueron incluidos RN con edad gestacional ≥ a 35 semanas, con peso ≥ a 2000 gramos, luego de las 24 hs de vida hasta los 8 días; bajo consentimiento informado de los padres, durante un año. Los datos fueron consignados en una planilla de Microsoft Excel y procesado por el software IBM SPSS Statistics ®. Resultados: De 271 RN que ingresaron al estudio, en la primera medición con el Bilirrubinómetro transcutáneo, cumplían con criterios para toma de bilirrubina sérica 90 (33,2%) de ellos. En los restantes 181 RN (66,8%), los datos emparejados no estaban disponibles debido a que siguiendo las recomendaciones de las guías actuales no fue necesario medir la bilirrubina sérica. El valor del coeficiente de correlación para la primera medición fue r = 0.574. Para la segunda medición las medidas emparejadas estaban disponibles para 131 RN. En este caso se encontró correlación positiva entre ambos métodos de 0,590. Conclusión: La bilirrubina transcutánea puede utilizarse en forma rápida, segura y válida, como un test de screening para la detección de hiperbilirrubinemia y podría evitar una proporción importante de toma de muestras sanguíneas, mejorando la seguridad del paciente.


Introduction: The guidelines for prevention and treatment of neonatal hyperbilirubinemia recommend measurement of total serum bilirubin (BST) or transcutaneous bilirubin (BTc) to determine the degree of jaundice before discharge of the newborn (NB); the latter non-invasive method provides instant information which is superior to the clinical evaluation. Despite this, it has not yet been systematically applied in hospitals in Paraguay. Objective: to evaluate transcutaneous measurement of bilirubin concentration as compared to serum bilirubin levels prior to discharge in our setting. Materials and Methods: This was an observational, cross-sectional, descriptive study with an analytical component. For a period of one year, we tracked NBs with a gestational age ≥ 35 weeks, weighing ≥ 2000 grams, from 24 hours of life until 8 days of life, obtaining the informed consent of the parents. The data was entered in a Microsoft Excel spreadsheet and processed by the IBM SPSS Statistics ® software. Results: Of 271 NBs who entered the study, 90 (33.2%) met criteria for measurement of serum bilirubin at their first measurement with the transcutaneous bilirubinometer. In the remaining 181 RN (66.8%), the paired data were not available as measurement of serum bilirubin was not required per the recommendations of current guidelines. The correlation coefficient value for the first measurement was r = 0.574. For the second measurement, paired measurements were available for 131 NBs. In this case, a positive correlation was found between both methods of 0.590. Conclusion: Transcutaneous bilirubin can be used quickly, safely and accurately as a screening test for the detection of hyperbilirubinemia and could avoid a significant proportion of blood sampling, improving patient safety.

ABSTRACT

Objetivo: Describir la prevalencia y factores asociados a la ictericia neonatal en recién nacidos. Materiales y métodos: Estudio de revisión, descriptivo transversal. Las bases de datos de revistas médicas científicas empleadas principalmente fueron PubMed y Scielo. Resultados: Hasta la actualidad a nivel mundial se reportan casos de hiperbilirrubinemia neonatal. Las últimas prevalencias encontradas en la literatura son 55,2% en Estados Unidos, 29 % en Nepal, 6,7% en Nigeria y en Europa valores que van del 6% al 59%. Mientras que en América del Sur Bolivia y Chile han reportado altas prevalencias de 76,3% y 69,2%, y en Perú alrededor de 7%. Entre los factores de riesgo asociados principalmente se detallan bebé de sexo masculino, grupo sanguíneo del sistema ABO o de factor Rh, defectos de la membrana del eritrocito (esferocitosis hereditaria), deficiencias enzimáticas (deficiencia de glucosa 6 fosfato deshidrogenasa) y hemoglobinopatías. Conclusiones:La prevalencia de ictericia neonatal es variable a nivel mundial. Los pocos estudios realizados en Perú reportan prevalencia alrededor del 7%. Es necesario que se realicen más estudios para tener datos a nivel nacional que permitan establecer estrategias de control y tratamiento según las necesidades de la región. (AU)


Objective: To describe the prevalence and problems associated with neonatal jaundice. Materials and methods: Review study, cross-sectional descriptive. PubMed and Scielo were used as data bases. Results: 5Up to now, cases of neonatal hyperbilirubinemia are reported worldwide. The last prevalences found in the literature were 55.2 in the United States, 29% in Nepal, 6.7 in Nigeria, in Europe values ranging from 6% to 59%. While in South America Bolivia and Chile have reported high prevalences of 76.3% and 69.2%, and in Peru around 7%. Among the associated risk factors are mainly male baby, blood group of the ABO system or of the Rh factor, defects of the erythrocyte membrane (hereditary spherocytosis), enzymatic deficiencies (deficiency of glucose 6 phosphate dehydrogenase) and hemoglobinopathiesConclusions: The prevalence of neonatal jaundice is variable worldwide. The few studies conducted in Peru report a prevalence around 7%. It is necessary to carry out more studies in order to have data at the national level that allow establishing control and treatment strategies according to the needs of the region. (AU)

ABSTRACT

Resumen El síndrome del bebe bronceado es una rara discromía que se presenta como una complicación de la fototerapia en recién nacidos con ictericia neonatal. Aunque el fenotipo común se ha descrito en pacientes con hiperbilirrubinemia directa secundaria a colestasis, también se conocen casos con hiperbilirrubinemia indirecta en quienes se invierte el patrón de hiperbilirrubinemia e, incluso, otros con hiperbilirrubinemia indirecta aislada. La fisiopatología de la enfermedad sigue siendo motivo de controversia, por lo que no se ha establecido claramente cuál es la mejor aproximación diagnóstica y terapéutica. En general, el síndrome se considera leve y se resuelve con la suspensión de la fototerapia; no suele prolongarse más allá del periodo neonatal y no tiene secuelas a largo plazo. Sin embargo, su aparición constituye una contraindicación absoluta para continuar la fototerapia. En caso de persistir, se recomienda disminuir los niveles de bilirrubina y recurrir a la exanguinotransfusión, pero dado que esta implica riesgos para el neonato, una conducta adecuada sería suspender la fototerapia y reiniciarla si la bilirrubina directa disminuye y se ha descartado el compromiso colestásico, aunque siempre evaluando en forma seriada posibles manifestaciones de encefalopatía aguda por bilirrubina. El objetivo de este estudio fue presentar el caso de un recién nacido con incompatibilidad de grupo sanguíneo ABO que presentó el síndrome del bebé bronceado. El bebé respondió satisfactoriamente a la suspensión de la fototerapia y a su posterior reanudación, sin necesidad de recurrir a la exanguinotransfusión.


Abstract The bronze baby syndrome is an infrequent dyschromia resulting from phototherapy in newborn babies with neonatal jaundice. Even though the common phenotype has been described in patients with direct neonatal hyperbilirubinemia secondary to cholestasis, several cases of patients with indirect neonatal hyperbilirubinemia who have managed to reverse it have been reported, as well as patients with isolated hyperbilirubinemia. Currently, the physiopathology of this condition is still a subject of controversy and, therefore, there is a lack of clear conducts for its correct diagnosis and treatment. Generally, this syndrome has been considered as a mild condition that is resolved with the suspension of phototherapy. Its duration is usually not greater than the neonatal period, and it has no long-term sequelae. However, its occurrence is considered an absolute contraindication for the continuation of phototherapy. In case of persistence, the recommendation is to decrease bilirrubin levels and proceed with exchange transfusion; this procedure, however, represents risks for the newborn, so our recommendation is to suspend phototherapy and reinitiate it if the direct bilirrubin value decreases, and cholestasis compromise has been discarded. Serial evaluations of acute encephalopathy caused by bilirrubin are absolutely recommended. The objective of this paper was to describe the case of a newborn with ABO incompatibility who developed the bronze baby syndrome. This patient responded satisfactorily to the suspension and resumption of phototherapy without exchange transfusion.

ABSTRACT

O uso de esteroides anabólicos androgênicos é comum entre jovens praticantes de musculação, devido ao seu efeito trófico no tecido muscula. No entanto, seu abuso pode levar a danos teciduais dose-dependentes graves e irreversíveis. Foi relatado o caso de intoxicação hepática por droga anabolizante complicando com lesão renal aguda por hiperbilirrubinemia. Foram realizadas revisão de prontuário do paciente e pesquisa bibliográfica do assunto, após a assinatura de Termo de Consentimento Livre e Esclarecido. Um homem de 28 anos foi admitido neste hospital por icterícia, perda ponderal, febre alta, náuseas e prurido, sintomas estes iniciados 2 meses antes. À anamnese, revelou uso de estanozolol, testosterona e oximetolona em altas doses durante os 4 anos pregressos. Seus exames iniciais revelaram lesão hepática grave e azotemia, sendo o paciente diagnosticado com insuficiência renal aguda por lesão tubular pela hiperbilirrubinemia, necessitando de hemodiálise. O abuso de substâncias anabolizantes pode levar a complicações com risco de vida. São necessárias informação e divulgação das consequências do uso não terapêutico destas drogas, de modo a desestimular seu uso indiscriminado e a otimizar a habilidade dos setores de saúde em lidar com estes pacientes.(AU)


The use of anabolic androgenic steroids is common among young bodybuilders, because of their trophic effects on muscle tissue; however, the abuse of these substances may lead to dosedependent, severe and irreversible tissue damage. A case of liver poisoning from anabolic drug, complicated by acute kidney injury due to hyperbilirubinemia was reported. The patient's medical report review, and bibliographical research on the subject were conducted after the signing of the Free Informed Consent. A 28-year-old man was admitted in this hospital because of jaundice, weight loss, high fever, nausea and itching, which began 2 months earlier. At history taking, he revealed the use of stanozolol, testosterone, and oxymetholone in higher doses than recommended for 4 years. His first laboratorial tests revealed acute liver damage and azotemia, and the patient was diagnosed with acute kidney injury by tubular lesion caused by hyperbilirubinemia, and the need for hemodyalisis. The abuse of anabolic substances may lead to life-threatening complications. It is necessary to inform and disclose the consequences of non-therapeutic use of these drugs, in order to discourage its indiscriminate use, and to optimize clinical management of these patients in healthcare centers.(AU)

ABSTRACT

Aunque la ictericia afecta a más de la mitad de los neonatos en la primera semana de vida, sólo un grupo de ellos pueden desarrollar hiperbilirrubinemia severa y estar en riesgo de desarrollar encefalopatía bilirrubínica. La afectación neurológica puede presentarse con un cuadro agudo (la encefalopatía bilirrubínica aguda), la cual puede o no progresar a una forma crónica (Kernicterus), o con una constelación de síntomas sensoriales, motores y cognitivos, subagudos o crónicos, dependiendo de la presencia de factores de riesgo que aumentan la susceptibilidad al daño neurológico. La bilirrubina libre interactúa con citoquinas inflamatorias y es la responsable del daño neuronal y de las células de la glía en el sistema nervioso central. A pesar de las diferentes medidas de prevención de hiperbilirrubinemia severa, se siguen reportando casos de Kernicterus sobre todo en países en vías de desarrollo, en algunos de los cuales constituyen un problema de salud pública.


Although jaundice affects more than half of infants in the first week of life, only a few of them develop severe hyperbilirubinemia and are at risk of developing bilirubin encephalopathy. Neurological involvement may occur acutely (acute bilirubin encephalopathy,) which may or may not progress to a chronic form (Kernicterus), or with a constellation of sensory, motor and cognitive, subacute or chronic symptoms, depending on the presence of risk factors that increase susceptibility to neurological damage. Free bilirubin interacts with inflammatory cytokines and is responsible for neuronal and glial cell damage in the central nervous system. Despite different methods to prevent severe hyperbilirubinemia, Kernicterus cases continue to be reported, especially in developing countries, including some where this condition constitutes a public health problem.
