Objective: To compare the prognostic value of 3 diagnostic criteria of bronchopulmonary dysplasia (BPD) in preterm infants with gestational age<32 weeks. Methods: The retrospective cohort study was conducted to collect the clinical data of 285 preterm infants with BPD admitted to the Department of Neonatology, Children's Hospital Affiliated to Zhengzhou University from January 2019 to September 2021, who were followed up regularly after discharge. The primary composite adverse outcome was defined as death or severe respiratory morbidity from 36 weeks of corrected gestational age to 18 months of corrected age, and the secondary composite adverse outcome was defined as death or neurodevelopmental impairment. According to the primary or secondary composite adverse outcomes, the preterm infants were divided into the adverse prognosis group and the non-adverse prognosis group. The 2001 National Institute of Child Health and Human Development (NICHD) criteria, 2018 NICHD criteria, and 2019 Neonatal Research Network (NRN) criteria were used to diagnose and grade BPD in preterm infants. Chi-square test, Logistic regression analysis, receiver operating characteristic (ROC) curve and Delong test were used to analyze the prognostic value of the 3 diagnostic criteria. Results: The 285 preterm infants had a gestational age of 29.4 (28.1, 30.6) weeks and birth weight of 1 230 (1 000, 1 465) g, including 167 males (58.6%). Among 285 premature infants who completed follow-up, the primary composite adverse outcome occurred in 124 preterm infants (43.5%), and the secondary composite adverse outcome occurred in 40 preterm infants (14.0%). Multivariate Logistic regression analysis showed that severe BPD according to the 2001 NICHD criteria, gradeⅡand Ⅲ BPD according to the 2018 NICHD criteria and grade 2 and 3 BPD according to the 2019 NRN criteria were all risk factors for primary composite adverse outcomes (all P<0.05). ROC curve showed that the area under the curve (AUC) of the 2018 NICHD criteria and 2019 NRN criteria were both higher than that of the 2001 NICHD criteria (0.70 and 0.70 vs. 0.61, Z=4.49 and 3.35, both P<0.001), but there was no significant difference between the 2018 NICHD and 2019 NRN criteria (Z=0.38, P=0.702). Multivariate Logistic regression analysis showed that the secondary composite adverse outcomes were all associated with grade Ⅲ BPD according to the 2018 NICHD criteria and grade 3 BPD according to the 2019 NRN criteria (both P<0.05). ROC curve showed that the AUC of the 2018 NICHD criteria and 2019 NRN criteria were both higher than that of the 2001 NICHD criteria (0.71 and 0.71 vs. 0.58, Z=2.93 and 3.67, both P<0.001), but there was no statistically significant difference between the 2018 NICHD and 2019 NRN criteria (Z=0.02, P=0.984). Conclusion: The 2018 NICHD and 2019 NRN criteria demonstrate good and comparable predictive value for the primary and secondary composite adverse outcomes in preterm infants with BPD, surpassing the predictive efficacy of the 2001 NICHD criteria.

RESUMO Objetivo Comparar o tempo de transição alimentar e a forma de alimentação por via oral na alta hospitalar, entre recém-nascidos prematuros com diagnóstico de displasia broncopulmonar e prematuros sem o diagnóstico. Métodos Estudo transversal, retrospectivo com base na coleta de dados nos prontuários. Foram coletados dados de 78 recém-nascidos, em uma maternidade de referência. A amostra foi estratificada em dois grupos, de acordo com a presença do diagnóstico de displasia broncopulmonar, sendo um grupo de prematuros com displasia broncopulmonar e outro sem. Foram analisados o tempo de transição alimentar e o método de alimentação na alta hospitalar de ambos os grupos. Resultados Houve diferença significativa no tempo de transição alimentar e no método de alimentação na alta hospitalar entre os grupos. Os recém-nascidos pré-termo com displasia broncopulmonar apresentaram média de 18,03 (± 5,5) dias de transição e saíram em uso de mamadeira. Conclusão O grupo com displasia broncopulmonar necessitou de maior tempo de transição alimentar e teve menor frequência de aleitamento materno exclusivo, em relação ao grupo sem o diagnóstico.
ABSTRACT Purpose To compare the time of food transition and the form of oral feeding at hospital discharge, between premature newborns diagnosed with bronchopulmonary dysplasia and premature newborns without the diagnosis. Methods Cross-sectional, retrospective study based on data collection from medical records. Data were collected from 78 newborns, in a reference maternity hospital, in which the sample was stratified into two groups according to the presence or absence of the diagnosis of bronchopulmonary dysplasia. The time of food transition and the feeding method at hospital discharge were analyzed for both groups. Results There was a significant difference in the time of food transition and in the feeding method at hospital discharge between the groups. Preterm newborns with bronchopulmonary dysplasia had an average of 18.03 (± 5.5) transition days and left using a bottle. Conclusion The group with bronchopulmonary dysplasia required a longer time of food transition and fewer ( of its ) infants had exclusive breastfeeding compared to the group without the diagnosis.

Abstract Objectives: to determine the prevalence and factors associated with recurrent wheezing in the first year of life among premature newborns from Neonatal Intensive Care Units, in the city of Montes Claros, northern Minas Gerais. Methods: cross-sectional study, with data collection from medical records of a follow-up clinic, interviews with mothers and, eventually, search in hospital records. Bivariate analyzes were carried out between sociodemographic and clinical characteristics and recurrent wheezing. Variables associated up to the level of 20% were analyzed by binary logistic regression, and associations defined by the Odds Ratio and respective 95% confidence intervals. Only variables associated with a 5% significance level were maintained in the final model of logistic regression. Results: among 277 infants studied, about one fifth (21.3%) were extremely low birth weight preterm and more than half (60.7%) had birth weight below 1500 grams. The prevalence of recurrent wheezing was 14.4% (CI95% = 10.3-18.4). Mechanical ventilation (OR = 2.12; CI95% = 1.09-4.76; p = 0.030) and oxygen therapy time ≥ 15 days (OR = 2.49; CI95%= 1.12-5.00; p = 0.010) were the risk factors for the event. Conclusions: there is a high prevalence of recurrent wheezing in the evaluated group and the associated variables reiterate the risk of prolonged oxygen therapy and mechanical ventilation for premature newborns.
Resumo Objetivos: determinar a prevalência e fatores associados à sibilância recorrente no primeiro ano de vida entre recém-nascidos prematuros egressos de Unidades de Terapia Intensiva Neonatais, na cidade de Montes Claros, norte de Minas Gerais. Métodos: estudo transversal, com coleta de dados em prontuários de ambulatório de seguimento, entrevistas com mães e, eventualmente, consultas aos prontuários hospitalares. Foram realizadas análises bivariadas entre as características sociodemográficas e clínicas e a sibilância recorrente. As variáveis associadas ao desfecho até um nível de significância de p ≤20% foram analisadas por regressão logística binária e as associações definidas pelas Odds Ratios e respectivos intervalos de confiança de 95%. Somente variáveis associadas a um nível de significância de 5% foram mantidas no modelo final de regressão logística. Resultados: entre 277 crianças estudadas, cerca de um quinto (21,3%) eram prematuros de extremo baixo peso e mais da metade (60,7%) tinha peso de nascimento abaixo de 1500 gramas. A prevalência de sibilância recorrente foi de 14,4% (IC95%=10,3-18,4). Ventilação mecânica (OR=2,12; IC95%= 1,09-4,76; p=0,030) e tempo de oxigenioterapia ≥15 dias (OR=2,49; IC95%=1,12-5,00; p=0,010) foram os fatores de risco para o evento. Conclusão: existe uma elevada prevalência de sibilância recorrente no grupo avaliado e as variáveis associadas reiteram o risco do uso prolongado de oxigenioterapia e da ventilação mecânica para recém-nascidos prematuros.

La hipertensión pulmonar es una complicación frecuente de la displasia broncopulmonar. A pesar de su alta incidencia, existen pocos tratamientos disponibles. El epoprostenol y el treprostinil son análogos de las prostaglandinas I2, que activan la adenilato ciclasa e incrementan el adenosín monofosfato cíclico en las células de la musculatura lisa de la arteria pulmonar y pueden resultar eficaces en el tratamiento de estos pacientes. Se presenta el caso de un prematuro de extremado bajo peso con hipertensión pulmonar secundaria a displasia broncopulmonar grave, no respondedora a óxido nítrico inhalado y sildenafilo, que fue tratado con análogos de prostaglandinas I2. En nuestro paciente, este tratamiento evidenció mejoría clínica y ecocardiográfica significativa tras varias semanas de tratamiento.
Pulmonary hypertension is a common complication of bronchopulmonary dysplasia, with a high mortality rate. Despite the high incidence of pulmonary hypertension, there are few available treatments. Epoprostenol and treprostinil are prostaglandin I2 analogs that activate adenylate cyclase and increase cyclic adenosine monophosphate in the pulmonary arterial smooth muscle cells. Therefore, they may be an effective treatment for these patients. We report the use of prostaglandin I2 analogs in an extremely low birth weight preterm baby with severe bronchopulmonary dysplasia associated with pulmonary hypertension non-responding to inhaled nitric oxide and sildenafil. In our patient this treatment resulted in remarkable clinical and echocardiographic improvement, evident after a few weeks of treatment.

Introducción: La displasia broncopulmonar es la secuela más común relacionada con los recién nacidos prematuros de muy bajo peso al nacer, derivada de la inmadurez pulmonar y en algunos casos del tratamiento. Objetivo: Identificar los factores de riesgo maternos y neonatales asociados a displasia broncopulmonar en recién nacidos prematuros de muy bajo peso al nacer. Métodos: La muestra estuvo conformada por 205 recién nacidos prematuros de muy bajo peso al nacer en el Hospital Belén de Trujillo, durante el período 2008-2015. El grupo de casos y el de controles fueron 41 pacientes con diagnóstico de displasia broncopulmonar y 164 pacientes sin diagnóstico de este trastorno respiratorio y que se ajustaran a los criterios de exclusión. Resultados: Los factores de riesgo asociados a displasia broncopulmonar fueron dos o más episodios de sepsis tardía (OR= 5,12; IC95 por ciento: 1,87-14,06), la prematuridad extrema (OR= 4,86; IC95 por ciento: 1,71-13,80), el peso extremadamente bajo al nacer (OR= 2,72; IC95 por ciento: 0,93- 7,94) y la reanimación neonatal (OR= 2,28; IC95 por ciento: 0,89-5,87). Conclusiones: La prematuridad extrema y dos episodios o más de sepsis tardía fueron los factores de riesgo que más se relacionan con la aparición de displasia broncopulmonar en recién nacidos prematuros de muy bajo peso al nacer(AU)
Introduction: Bronchopulmonary dysplasia is the most common sequelae related to very low birth weight premature infants, and it is derived from pulmonary immaturity and in some cases from treatment. Objective: To identify maternal and neonatal risk factors associated with bronchopulmonary dysplasia in very low birth weight premature infants. Methods: The sample was composed of 205 very low birth weight premature infants at Belén of Trujillo Hospital during the period 2008-2015. The group of cases and controls were 41 patients with diagnosis of bronchopulmonary dysplasia and 164 patients with no diagnosis of this respiratory disorder, respectively, and that both groups adjusted with exclusion criteria. Results: Risk factors associated with bronchopulmonary dysplasia were 2 or more episodes of late onset sepsis (OR=5.12; IC95 percent: 1,87-14,06), extreme prematurity (OR= 4.86; IC95 percent: 1.7-13.80), extremely low birth weight (OR= 2.72; IC95 percent: 0.9-7.94) and neonatal resuscitation (OR= 2.28; IC95 percent: 0.89-5.87). Conclusions: Extreme prematurity and 2 or more episodes of late onset sepsis were the most associated risk factors to the onset of bronchopulmonary dysplasia in very low birth weight premature infants(AU)

RESUMO Objetivo: Comparar o desenvolvimento neuropsicomotor de lactentes nascidos prematuramente, com e sem displasia broncopulmonar, no primeiro ano de vida. Métodos: Estudo retrospectivo, do tipo transversal, realizado no período de 1º de janeiro de 2014 a 30 de dezembro de 2015, com lactentes prematuros, com peso < 1.500g ao nascer e diagnóstico de displasia broncopulmonar, na idade corrigida de 6 e 9 meses, avaliados pelo Teste de Triagem do Desenvolvimento DENVER II. As variáveis quantitativas foram descritas em médias, medianas e desvio padrão. Para as variáveis que apresentaram distribuição normal, aplicou-se o teste t de Student; do contrário, foi aplicado o teste de Mann-Whitney, considerando significância o valor de p < 0,05. As variáveis qualitativas foram descritas em frequências e porcentagens. Utilizou-se a regressão logística com análise da razão de chances para avaliar os efeitos das outras variáveis, como fatores de risco para alterações no desenvolvimento neuropsicomotor. Resultados: Os lactentes com displasia broncopulmonar apresentaram maior atraso no desenvolvimento neuropsicomotor quando comparados àqueles sem displasia broncopulmonar (p = 0,001). Os fatores associados com maior incidência para alterações no desenvolvimento neuropsicomotor, além da displasia broncopulmonar, foram: esteroide antenatal, sexo, peso ao nascimento, escore de Apgar no quinto minuto, Score for Neonatal Acute Physiology with Perinatal Extension, tempo de oxigenoterapia, ventilação mecânica e internação. Outras variáveis também podem ter influenciado o resultado, como uso de drogas pelas mães dos lactentes com displasia broncopulmonar. Conclusão: A displasia broncopulmonar associada a outros fatores pré e pós-natais pode ser considerada fator de risco para o atraso do desenvolvimento neuropsicomotor em lactentes nascidos prematuramente e com peso inferior a 1.500g, no primeiro ano de vida.
ABSTRACT Objective: To compare the neuropsychomotor development in the first year of life of premature infants with and without bronchopulmonary dysplasia. Methods: A cross-sectional retrospective study was conducted between January 1, 2014, and December 30, 2015, with premature infants weighing < 1,500g at birth and diagnosed with bronchopulmonary dysplasia at the corrected ages of 6 and 9 months, assessed using the DENVER II Developmental Screening Test. Quantitative variables were described as the means, medians and standard deviations. Variables with normal distribution were tested using Student's t test; otherwise, the Mann-Whitney test was used, considering significance at p-value < 0.05. Qualitative variables were expressed as frequencies and percentages. Logistic regression was used with odds ratio analysis to evaluate the effects of other variables as risk factors for changes in neuropsychomotor development. Results: Infants with bronchopulmonary dysplasia showed greater developmental delay compared with those without bronchopulmonary dysplasia (p-value = 0.001). The factors associated with a higher incidence of changes in neuropsychomotor development, in addition to bronchopulmonary dysplasia, were antenatal steroid, gender, birth weight, 5-minute Apgar score, Score for Neonatal Acute Physiology-Perinatal Extension, duration of oxygen therapy, duration of mechanical ventilation and length of hospital stay. Other variables may also have influenced the result, such as drug use by mothers of infants with bronchopulmonary dysplasia. Conclusion: Bronchopulmonary dysplasia associated with other pre- and postnatal factors may be considered a risk factor for delayed neuropsychomotor development in the first year of life in premature infants born weighing less than 1,500g.

Resumen Hace 50 años Northway describió la Displasia Broncopulmonar (DBP), en nacidos de pretérmino expuestos a ventilación mecánica. Desde entonces, ha aumentado la sobrevida de ellos; sin embar go, ha aparecido una "nueva DBP" y la incidencia de esta no ha disminuido. Una de las caracte rísticas de esta patología es la remodelación vascular anómala, que en su expresión más severa se conoce como Hipertensión Pulmonar (HP); con una incidencia de 17%, que es proporcional a la severidad de la DBP (33% en DBP severa); y como un factor de mortalidad (hasta un 48% mortali dad a 2 años con HP por DBP). Debido a esto resulta importante conocer los métodos diagnósticos y alternativas terapéuticas, tema que se discute en esta revisión. Considerando la alta mortalidad de la asociación HP-DBP, adquiere importancia una estrategia de tamizaje en la población de riesgo. El gold standard para el diagnóstico de HP es el cateterismo cardíaco, sin embargo, el ecocardio-grama transtorácico es una herramienta útil para el tamizaje y diagnóstico de HP en pacientes dis-plásicos, con mediciones cuantitativas y cambios cualitativos en la evaluación diagnóstica. A nivel sanguíneo el péptido natriurético tipo B (BNP), ha mostrado ser útil en el seguimiento; en cuanto a imágenes, la tomografía computarizada se utiliza en casos severos. En cuanto a las terapias, se han propuesto el óxido nítrico inhalado como vasodilatador pulmonar, los inhibidores de la fosfodies-terasas -sildenafil-, los antagonistas de la endotelina -bosentán- y los análogos de prostaciclinas -iloprost-. Aún no se cuenta con evidencia de alta calidad para su uso, dosis y duración del trata miento, pero hay variadas experiencias clínicas. Además, es relevante el cuidado interdisciplinario, destacando optimizar la nutrición. El desafío es lograr una prevención efectiva de la DBP y de sus complicaciones. Un protocolo de tamizaje de HP debe asociarse a una estratificación de riesgo y directrices de tratamiento.
Abstract 50 years ago, Northway described Broncopulmonary Dysplasia (BPD) in preterm infants exposed to mechanical ventilation. Since then, their survival has increased, nevertheless a "new BPD" has appeared and its incidence has not diminished. One of the characteristics of this pathology is the the abnormal vascular remodeling, which in its most severe expression is known as Pulmonary Hyper tension (PH); with an incidence of 17% in patients with BPD, which is proportional to the severity of the disease (33% in severe BPD), and as mortality factor (up to 48% 2-year mortality in PH-BPD). Thereby, it is important to know the diagnostic methods and therapeutic alternatives, topics discus sed in this review. Considering the high mortality in BPD associated PH, screening strategies in at risk population become important. The gold standard is cardiac catheterization; however, transtho-rathic echocardiography is a useful tool for the screening and diagnosis of PH in displasic patients, using cuantitive measures and cualitative changes in the evaluation. Seric type-B natriuretic peptide has shown to be useful for follow-up; regarding images, CT scan is used in severe cases. In terms of therapy; inhaled Nitric Oxide as a pulmonary vasodilator, phosphodiesterase inhibitors -sildenafil-, endotelin antagonists -bosentan-, and prostacyclin analogues -iloprost-, have been proposed. Their use, dosis and treatment lenght still lack support of high quality evidence, but diverse clinical expe riences have been described. Interdisciplinary care is also important, highlighting to optimize nu trition. Therefore, the challenge is to effectively prevent BPD and its complications. A PH screening protocol should be associated with risk stratification and treatment guidelines.

ABSTRACT CONTEXT AND OBJECTIVE: Children born prematurely often have worse cognitive performance than those born at term regarding skills such as memory, attention and processing speed. Bronchopulmonary dysplasia may compromise cognitive development. The aims here were: a) To describe the cognitive performance of preterm infants with very low birth weight; b) To investigate its association with bronchopul-monary dysplasia adjusted for sociodemographic, neonatal and post-neonatal factors. DESIGN AND SETTING: Cross-sectional study developed in a public tertiary-care hospital. METHODS: To evaluate cognition among 112 children, we applied an intelligence scale (Wechsler scale). The average scores for children with and without bronchopulmonary dysplasia were compared across the fve domains of the scale. Associations with bronchopulmonary dysplasia were investigated for domains that showed signifcant diferences between the two groups. Associations between exposure and outcome were estimated via multivariate logistic regression. RESULTS: There were no diferences in averages for the full-scale intelligence quotient, verbal intelligence quotient, performance intelligence quotient and general language composite domains. The processing speed quotient was the only domain that presented a signifcant diference between the two groups (P = 0.02). Among the children with bronchopulmonary dysplasia, low full-scale intelligence quotient was observed in 28.1%. In the multivariate analysis, bronchopulmonary dysplasia (odds ratio: 3.1; 95conf-dence interval: 1.1-8.7) remained associated with the outcome of processing speed quotient. CONCLUSION: Bronchopulmonary dysplasia was an independent risk factor for alteration of the processing speed quotient.
RESUMO CONTEXTO E OBJETIVO: Crianças nascidas prematuras com frequência apresentam pior desempenho cognitivoque as nascidas a termo em habilidades como memória, atenção, velocidade de processamento. A displasia broncopulmonar pode comprometer o desenvolvimento cognitivo. Os objetivos aqui foram: a) Descrever o desempenho cognitivo de crianças nascidas prematuras com muito baixo peso; b) Investigar sua associação com a displasia broncopulmonar ajustada para fatores sócio-demográfcos, neonatais e pós-neonatais. TIPO DE ESTUDO E LOCAL: Estudo transversal desenvolvido em hospital público de cuidados terciários. MÉTODOS: Para a avaliação cognitiva de 112 crianças, aplicamos a escala de inteligência (Wechsler scale). Foram comparadas as médias dos escores das crianças com e sem displasia broncopulmonar nos cinco domínios da escala. A associação com a displasia broncopulmonar foi investigada para os domínios que apresentaram diferença signifcativa entre os dois grupos. A associação entre a exposição e o desfecho foi estimada por regressão logística multivariada. RESULTADOS: Não houve diferença entre as médias dos domínios do quociente de inteligência total, quociente de inteligência verbal, quociente de inteligência de execução e composto de linguagem geral. O quociente de velocidade de processamento foi o único domínio que apresentou diferença signifcativa entre os dois grupos (P = 0,02). Entre as crianças com displasia broncopulmonar, quociente de inteligência total baixo ocorreu em 28,1%. Na análise multivariada, a displasia broncopulmonar (odds ratio: 3,1; intervalo de confança: 1,1-8,7) permaneceu associada ao desfecho quociente de velocidade de processamento. CONCLUSÃO: A displasia broncopulmonar foi um fator de risco independente para alteração no quociente de velocidade de processamento.

OBJECTIVE: To assess the prevalence, spirometry findings and risk factors for asthma in schoolchildren who were very low birth weight infants with and without bronchopulmonary dysplasia. METHODS: Observational and cross-sectional study. The parents and/or tutors answered the International Study of Asthma and Allergies in Childhood questionnaire. The schoolchildren were submitted to the skin prick test and spirometry assessment. RESULTS: 54 schoolchildren who were very low birth weight infants were assessed and 43 met the criteria for spirometry. Age at the assessment (bronchopulmonary dysplasia=9.5±0.85; without bronchopulmonary dysplasia=10.1±0.86 years) and birth weight (bronchopulmonary dysplasia=916.7±251.2; without bronchopulmonary dysplasia=1171.3±190.5g) were lower in the group with bronchopulmonary dysplasia (p<0.05). The prevalence of asthma among very low birth weight infants was 17/54 (31.5%), being 6/18 (33.3%) in the group with bronchopulmonary dysplasia. There was an association between wool blanket use in the first year of life (p=0.026) with the presence of asthma at school age. The skin prick test was positive in 13/17 (76.5%) and 23/37 (62.2%) of patients with and without asthma, respectively. The schoolchildren with asthma had lower z-score values of forced expiratory flow between 25% and 75% of forced vital capacity (n=16;−1.04±1.19) when compared to the group of patients without asthma (n=27;−0.380.93) (p=0.049). There was no difference between the spirometry variables in the groups regarding the presence or absence of bronchopulmonary dysplasia. CONCLUSIONS: Very low birth weight infants with and without bronchopulmonary dysplasia showed a high prevalence of asthma (33.3% and 30.6%, respectively). Pulmonary flow in the small airways was lower in children with asthma.
OBJETIVO: Avaliar prevalência, espirometria e fatores de risco para asma em escolares que foram recém-nascidos de muito baixo peso com e sem displasia broncopulmonar. MÉTODOS: Estudo observacional e transversal. Aplicou-se aos pais e/ou responsáveis o questionário International Study of Asthma and Allergies in Childhood. Foi feito teste cutâneo de hipersensibilidade imediata e espirometria nos escolares. RESULTADOS: Avaliados 54 escolares que foram recém-nascidos de muito baixo peso e 43 preencheram critérios para espirometria. A idade na avaliação (displasia broncopulmonar=9,5±0,85; sem displasia broncopulmonar=10,1±0,86 anos) e o peso de nascimento (displasia broncopulmonar=916,7±251,2; sem displasia broncopulmonar=1.171,3±190,5 g) foram menores no grupo com displasia broncopulmonar (p<0,05). A prevalência de asma entre os recém-nascidos de muito baixo peso foi de 17/54 (31,5%); no grupo com displasia broncopulmonar, de 6/18 (33,3%). Houve associação entre uso de cobertor de lã no primeiro ano de vida (p=0,026) com presença de asma na idade escolar. O teste cutâneo de hipersensibilidade imediata foi positivo em 13/17 (76,5%) e 23/37 (62,2%) nos grupos com e sem asma, respectivamente. Os escolares com asma apresentaram menores valores em z-score do fluxo expiratório forçado entre 25% e 75% da capacidade vital forçada (n=16; −1,04±1,19) comparados com os do grupo de pacientes sem asma (n=27; −0,38±0,93) (p=0,049). Não houve diferença entre as variáveis da espirometria no grupo com relação à presença ou não de displasia broncopulmonar. CONCLUSÕES: Os recém-nascidos de muito baixo peso, com e sem displasia broncopulmonar, apresentaram prevalência elevada de asma (33,3% e 30,6%, respectivamente). Os fluxos pulmonares das pequenas vias aéreas foram menores nos escolares com asma.

Bronchopulmonary dysplasia is one of the most common pediatric chronic lung diseases. In the recent decades the advances made in perinatal care and the increase survival of extreme preterm have shown an overall change in the characteristics of this disease giving rise to the concept of new dysplasia. In the development of the disease is essential the exposure of the immature lung to various factors such as nutritional deficiency, pre and post-natal infections, persistent ductus arteriosus, and genetic susceptibility. This article reviews the most important characteristics of this disease, treatment and follow-up.
La displasia broncopulmonar (DBP) es una de las enfermedades pulmonares crónicas frecuentes en pediatría. Los avances experimentados en las últimas décadas en cuidados perinatales y la sobrevida de prematuros cada vez más extremos han demostrado un cambio global en las características de esta enfermedad dando lugar al concepto de nueva displasia, en cuyo desarrollo son fundamentales la exposición del pulmón inmaduro a diversos factores como deficiencia nutricional, infecciones pre y post-natales, ductus arterioso persistente, y susceptibilidad genética. El presente articulo revisa las características más relevantes de esta patología, su enfrentamiento global, manejo y seguimiento ambulatorio.

OBJECTIVES: To compare mortality and morbidity in very low birth weight infants (VLBWI) born to women with and without diabetes mellitus (DM). METHODS: This was a cohort study with retrospective data collection (2001-2010, n = 11.991) from the NEOCOSUR network. Adjusted odds ratios and 95% confidence intervals were calculated for the outcome of neonatal mortality and morbidity as a function of maternal DM. Women with no DM served as the reference group. RESULTS: The rate of maternal DM was 2.8% (95% CI: 2.5-3.1), but a significant (p = 0.019) increase was observed between 2001-2005 (2.4%, 2.1-2.8) and 2006-2010 (3.2%, 2.8-3.6). Mothers with DM were more likely to have received a complete course of prenatal steroids than those without DM. Infants of diabetic mothers had a slightly higher gestational age and birth weight than infants of born to non-DM mothers. Distribution of mean birth weight Z-scores, small for gestational age status, and Apgar scores were similar. There were no significant differences between the two groups regarding respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage, periventricular leukomalacia, and patent ductus arteriosus. Delivery room mortality, total mortality, need for mechanical ventilation, and early-onset sepsis rates were significantly lower in the diabetic group, whereas necrotizing enterocolitis (NEC) was significantly higher in infants born to DM mothers. In the logistic regression analysis, NEC grades 2-3 was the only condition independently associated with DM (adjusted OR: 1.65 [95% CI: 1.2 -2.27]). CONCLUSIONS: VLBWI born to DM mothers do not appear to be at an excess risk of mortality or early morbidity, except for NEC. .
OBJETIVOS: Comparar mortalidade e morbidade em crianças de muito baixo peso (MBP) filhas de mães com e sem diabetes mellitus (DM). MÉTODOS: Estudo de coorte com coleta retrospectiva de dados (2001-2010, n = 11.991) da rede Neocosur. Odds ratios ajustados foram calculados para mortalidade e morbilidade neonatal em função da DM materna. Mulheres sem DM serviram como grupo de referência. RESULTADOS: A taxa de DM materna foi de 2,8% (IC 95% 2,5-3,1), mas um aumento significativo (p = 0,019) entre 2001-2005 (2,4%) e 2006-2010 (3,2%) foi observado. As mães com DM eram mais propensas a ter recebido um curso completo de esteroides pré-natais do que as sem DM. Os bebês de mães diabéticas tinham uma idade gestacional e peso ao nascer um pouco maior do que crianças filhas de não DM. A distribuição dos escores z do peso ao nascer, pequeno para idade gestacional e de Apgar foi semelhante. Não houve diferenças significativas entre os dois grupos em termos de síndrome do desconforto respiratório, displasia broncopulmonar, hemorragia intraventricular, leucomalácia periventricular e persistência do ductus arteriosus. Mortalidade na sala de parto, mortalidade total, necessidade de ventilação mecânica e taxas de sepse neonatal precoce foram significativamente menores no grupo diabético, enquanto enterocolite necrosante (NEC) foi significativamente maior em recém-nascidos de mães diabéticas. Em análises de regressão logística NEC foi a única condição independentemente associada com DM (OR ajustado 1,65 [IC 95% 1,21 -2,27]). CONCLUSÕES: Crianças MBP de DM não parecem estar em um excesso de risco de mortalidade ou morbidade precoce, exceto NEC. .

Conflicting results on the influences of histologic chorioamnionitis (HC) on neonatal morbidities might be partly originated from using different definition of HC. The aim of this study was to determine the relationship between HC and neonatal morbidities using definition of HC that reflects the site and extent of inflammation. This was a retrospective cohort study of 261 very low birth weight (VLBW) infants admitted at a tertiary academic center. Based on the site of inflammation, HC was categorized: any HC; amnionitis; funisitis; amnionitis+funisitis. The extent of inflammation in each site was reflected by sub-defining high grade (HG). The incidences of morbidities in infants with and without HC were compared. The bronchopulmonary dysplasia (BPD) rate was significantly higher in infants with amnionitis and the severe retinopathy of prematurity (ROP) rate was significantly higher in infants with any HC and funisitis. After adjustment for both gestational age and birth weight, the respiratory distress syndrome (RDS) rate was significantly lower in infants with all categories of HC except for HG amnionitis and HG funisitis, which are not associated with lower RDS rate. HG amnionitis was significantly associated with increased BPD rate but the association of HC with severe ROP disappeared. In conclusion, HC is significantly associated with decreased RDS and HG amnionitis with increased BPD while lacking association with other neonatal morbidities in VLBW infants. The association with HC and neonatal morbidities differs by the site and extent of chorioamnionitis.

The aim of this study was to observe the effects of prophylactic palivizumab on hospitalization secondary to respiratory syncytial virus (RSV) infection (RSVhospitalization) in former very low birth weight infants (VLBWI) with bronchopulmonary dysplasia (BPD). This study also sought to identify the risk factors of RSVhospitalizationin this particular infant population. A prospective observational study was conducted between September 2007 and April 2008 in seven Korean hospitals. Children with a history of very low birth weight, a diagnosis of BPD and who were <2 yr old at the onset of the RSV season were included in this study. Palivizumab injections were administered monthly for a maximum of five months during the RSV season. RSVhospitalization rates were reviewed, and RSVhospitalization rates between subgroups were categorized by gestational age, birth weight, and duration of ventilator care. A total of 90 subjects completed the follow-up interviews. The mean gestational age at birth was 26.1+/-1.7 weeks, and the mean birth weight was 889.4+/-222.2 g. The incidence of RSVhospitalization in the study population was 8.9% (8/90), and the mean hospital stay was 11.0+/-5.5 days, including one death. There were no statistically significant differences in the patients' demographic characteristics or risk factors for RSV hospitalization. When subgroup analyses were conducted, there were still no statistically significant differences. The administration of palivizumab prophylaxis during the entire RSV season is important in VLBWI with BPD, regardless of their gestational age and birth weight, or previous ventilator dependency.

La displasia broncopulmonar (enfermedad pulmonar crónica de la infancia) constituye un grupo heterogéneo de enfermedades de etiopatogenia multifactorial y fisiopatología multisistémica. Su frecuencia ha aumentado en los últimos años debido principalmente a la mayor supervivencia de los recién nacidos prematuros de muy bajo peso al nacer que presentan interrupción del desarrollo vascular y pulmonar unido a alteraciones funcionales generadas por el déficit de surfactante y relacionadas con la inmadurez. Sin embargo, se ha controlado la gravedad de estos cuadros gracias a los cambios realizados en la práctica clínica. Para un adecuado control y seguimiento multidisciplinario, abordamos esta afección con el objetivo de elaborar un plan de actuación cuando estos neonatos se encuentran en su hogar tras el alta hospitalaria...

OBJETIVO: Examinar a relação entre vacinação primária de recém-nascidos pré-termo e razões de prevalência de fatores associados a eventos cardiorrespiratórios indesejados, seguindo recomendações do Comitê Consultivo de Práticas de Imunização do Centers for Disease Control and Prevention para imunização de recém-nascidos pré-termo aos 2 meses de idade cronológica. MÉTODOS: Estudo retrospectivo de 2 anos de recém-nascidos de muito baixo peso que receberam vacinação primária. Foram registrados eventos cardiorrespiratórios maiores, como apneia, bradicardia, dessaturação de SpO2, e eventos menores, como instabilidade de temperatura, comportamento inapropriado e reações locais. Foi calculada a razão de prevalência com intervalo de confiança de 95% para fatores associados entre recém-nascidos com e sem eventos cardiorrespiratórios. RESULTADOS: Foram estudados 80 recém-nascidos (mediana de peso ao nascer [:intervalo]: de 970 g [:428-1.490]:), idade gestacional de 27,4 semanas (23,3-33). Ocorreram reações adversas em 35 (44%): eventos menores em 19 (24%) pacientes, eventos maiores em 28 (35%). Recém-nascidos com eventos maiores tiveram idade gestacional significativamente menor (p = 0,008) e incidência mais alta de displasia broncopulmonar (71% versus 48%; p < 0,05). Em recém-nascidos de muito baixo peso com eventos maiores, o número de casos de dessaturação de O2 antes da vacinação foi 3,40 (1,41-8,23) vezes maior, e o tratamento com metilxantina para síndrome de apneia e bradicardia foi 8,05 (2,50-25,89) vezes maior em comparação com recém-nascidos sem eventos maiores. CONCLUSÃO: Eventos cardiorrespiratórios maiores ocorreram em mais de 1/3 de todos os recém-nascidos de muito baixo peso após a vacinação. Os fatores associados foram baixa idade gestacional, displasia broncopulmonar, tratamento com metilxantina e dessaturação de O2 persistente antes da vacinação. A vacinação primária de recém-nascidos de muito baixo peso deve ser realizada sob monitoramento contínuo de parâmetros vitais.
OBJECTIVE: To examine the relationship between primary vaccination of preterm infants and prevalence ratios of associated factors for unwanted cardiorespiratory events, following the recommendation of the Centers for Disease Control and Prevention Advisory Committee on Immunization Practices for immunization of preterm infants at 2 months of chronological age. METHODS: Two-year retrospective study of very low birth weight infants receiving their primary vaccination. Major cardiorespiratory events, such as apnea, bradycardia, SpO2 desaturation, and minor adverse events, such as temperature instability, poor handling and local reactions, were recorded. Prevalence ratio with 95% confidence interval for associated factors between infants with and without cardiorespiratory events was calculated. RESULTS: Eighty neonates were studied (median [:range]: birth weight 970 g [:428-1,490]:), gestational age of 27.4 weeks (23.3-33). Adverse reactions occurred in 35 (44%): minor events in 19 (24%) patients, major events in 28 (35%). Infants with major events had significantly lower gestational age (p = 0.008) and a higher incidence of bronchopulmonary dysplasia (71% vs. 48%; p < 0.05). In very low birth weight infants with major events, O2 desaturations before vaccination were 3.40 (1.41-8.23) times higher and treatment with methylxanthines for apnea and bradycardia syndrome was 8.05 (2.50-25.89) times higher compared to infants without major events. CONCLUSION: Major cardiorespiratory events occurred in over 1/3 of all very low birth weight infants after vaccination. Associated factors were low gestational age, bronchopulmonary dysplasia, methylxanthine treatment, and persisting O2 desaturations before vaccination. Primary vaccination of very low birth weight infants should be performed under continuous monitoring of vital parameters.

Objetivo: determinar la necesidad de oxígeno suplementario en diferentes estados de comportamiento en una población de recién nacidos prematuros. Pacientes y método: este es un estudio prospectivo, descriptivo, longitudinal. Recién nacidos prematuros consecutivos cumplieron con los criterios de inclusión: edad gestacional <= 32 semanas y/o peso al nacer <= 1.500g. Se estudiaron 105 prematuros con o sin DBP a las 36 semanas de edad gestacional. Las oximetrías se realizaron a las 36 semanas de edad gestacional. Resultados: el grupo de BPD presentó menor edad gestacional, peso al nacer, perímetro craneal y el número de controles médicos durante el embarazo que en el grupo sin DBP. Los principales hallazgos fueron las caídas de saturación durante el sueño y en algunos casos durante la alimentación. Discusión: las diferencias en las variables clínicas entre ambos grupos se han reportado en diferentes estudios. A pesar de que oximetrías patológicas son más frecuentesen los pacientes con DBP, algunos prematuros sin DBP también mostraron resultados anormales. Conclusión: los beneficios reales de medir la saturaciónde oxigeno a las 36 semanas de edad gestacional se reflejan en una mejor gestión del aporte de oxigeno suplementario en los prematuros con y sin DBPI gualmente la estimulación de las funciones de la oro-faringe conducen a una mejor oxigenación durante la alimentación. Ambos hechos tienden a optimizar el crecimiento y desarrollo de estas poblaciones.

OBJECTIVE: To assess pulmonary function and the prevalence of atopy in school-age children who were very low birth weight as infants and to compare those who had bronchopulmonary dysplasia to those who did not. METHOD: We studied 85 (39 male and 46 female) at a mean age of 84 (range, 62 to 107) months who were very low birth weight infants. Bronchopulmonary dysplasia was defined as oxygen dependency at 36 weeks gestational age. We excluded 8 patients (4 for cerebral palsy and 4 for no collaboration). Detailed perinatal and clinical data were collected. Lung function was evaluated using conventional spirometry. Atopy (assessed by the allergy skin-prick test) was considered when at least one positive skin test occurred in a panel of the most common environmental allergens in the local region. Comparisons between the bronchopulmonary dysplasia and no bronchopulmonary dysplasia groups were performed using the Mann-Whitney, x2 and Fisher's exact tests. RESULTS: We compared the bronchopulmonary dysplasia (n = 13) and no bronchopulmonary dysplasia (n = 64) groups. Atopy was observed in 4 (30.8 percent) of the bronchopulmonary dysplasia patients and in 17 (26.6 percent) of the no bronchopulmonary dysplasia patients (p = 0.742). Two (15.4 percent) patients with bronchopulmonary dysplasia had a family history of atopy vs. 17 (26.6 percent) in the no bronchopulmonary dysplasia group (p = 0.5). Lung function tests showed airway obstruction in 2 (15.4 percent) of the bronchopulmonary dysplasia patients and in 10 (15.6 percent) of the no bronchopulmonary dysplasia patients (p = 1.0). Four (33.3 percent) of the bronchopulmonary dysplasia patients had small airway obstruction vs. 14 (22.2 percent) of the no bronchopulmonary dysplasia patients (p = 0.466). CONCLUSION: Our data showed no significant differences in lung function between bronchopulmonary dysplasia and no bronchopulmonary dysplasia patients at school age and no evidence of an association between atopy and bronchopulmonary dysplasia.

OBJECTIVE: The study aimed to assess bronchopulmonary dysplasia (BPD) as a predisposing factor for alteration in the psychomotor development index (PDI) in premature infants and verify the incidence of neuromotor alterations at 6 months corrected age. METHOD: This was a prospective cohort study that followed the neuromotor development of 152 very low birth weight premature infants, with psychomotor development index as the outcome. The study used the Bayley Scale of Infant Development at 6 months corrected age, and neurological examination. RESULTS: Incidence of BPD was 13.2 percent (n=20). Logistic regression analysis showed an association between BPD and altered psychomotor development index (OR 3.98; 95 percentCI: 1.04-15.1) after adjusting for confounding variables. Neurological examination was altered in 67.1 percent of the 152 infants. CONCLUSION: Bronchopulmonary dysplasia acted as an independent predisposing factor for alteration in the psychomotor development index in premature infants at 6 months corrected age.
OBJETIVO: Avaliar a displasia broncopulmonar (DBP) como fator predisponente para alteração no índice de desenvolvimento psicomotor em prematuros e verificar a incidência das alterações neuromotoras aos 6 meses de idade corrigida. MéTODO: Estudo de coorte prospectivo que acompanhou o desenvolvimento neuromotor de 152 prematuros de muito baixo peso, cujo desfecho foi o desenvolvimento psicomotor. Utilizou-se a Bayley Scale of Infant Development aos 6 meses de idade corrigida e exame neurológico. RESULTADOS: A incidência de DBP foi de 13,2 por cento (n=20). A análise de regressão logística mostrou associação entre a DBP e alteração no índice de desenvolvimento psicomotor (RC 3,98 IC 95 por cento:1,04-15,1) após ajuste para as variáveis de confundimento. O exame neurológico apresentou-se alterado em 67,1 por cento das 152 crianças. CONCLUSão: A displasia broncopulmonar atuou como fator predisponente independente para alteração no índice de desenvolvimento psicomotor em prematuros aos 6 meses de idade corrigida.

This study was performed to evaluate the utilization and outcomes of palivizumab in high risk children born prematurely with chronic lung disease (CLD). A retrospective review of 128 patients was conducted from September 2004 to March 2009 at the Ajou University Hospital. All patients were diagnosed with CLD, were born at < or =35 weeks of gestation, were <2 yr old at the onset of respiratory syncytial virus (RSV) season, and had received medical therapy within six months prior to the RSV season. Fifty-three patients did not receive palivizumab prophylaxis and 75 patients received at least one dose of palivizumab. There were no statistically significant differences between the patients with and without palivizumab prophylaxis with regard to demographic characteristics and risk factors for RSV infection. There were no systemic adverse responses. Compliance with the course of prophylaxis was 92.2%. Hospitalization associated with RSV occurred in 12 cases (22.6%) in the group without prophylaxis and in three cases (4.0%) with prophylaxis. Palivizumab prophylaxis significantly reduced the frequency of RSV-related hospitalization in preterm children with CLD. This is the first retrospective review of palivizumab prophylaxis in Korea. Palivizumab is effective and well tolerated in high risk prematurely born children.
