ABSTRACT

Introdução:A enterocolite necrosante é uma doença que pode afetar o trato gastrointestinal de recém-nascidos,cujas manifestações clínicas podem ser caracterizadas por vômitos biliosos, sangue nas fezes, distensão abdominal, além de alterações nos parâmetros hemodinâmicos e instabilidade térmica. As populações mais vulneráveis a essa enfermidade são recém-nascidos de baixo peso,expostos ao ambiente de terapia intensiva neonatal. Objetivos: Identificar o perfil de recém-nascidos e os fatores maternos e neonatais associados à ocorrência de óbitos por enterocolite necrosante, em maternidade de referência do Ceará-Brasil. Metodologia: Trata-se de coorte retrospectiva, estudo que objetiva a descrição da incidência de determinado evento ao longo do tempo, além do estabelecimento de relações causais entre os fatores associados ao acontecimento. Incluíram-serecém-nascidos que tiveram óbitos por enterocolite necrosante entre 2019 e 2021, comficha de investigação de óbitos neonatais preenchida corretamente, não sendo excluído nenhum recém-nascido, totalizando amostra de 29 óbitos.Resultados: Identificou-se que o perfil dos recém-nascidos foi,em maioria, deprematuros e com baixo peso e fatores de risco para outras doenças associadas,como a sepse, o que acarretourealização de procedimentos invasivos e internação em ambiente de terapia intensiva neonatal.Conclusões: A prematuridade e o baixo peso ao nascer foram as variáveis relevantes no estudo e podem estar associadas à piora das condições clínicas do recém-nascido e ao desenvolvimento de enterocolite necrosante (AU).


Introduction: Necrotizing Enterocolitis is a disease that can affect the gastrointestinal tract of newborns, whose clinical manifestations can be characterized by bilious vomiting, blood in stool, abdominal distension, in addition to changes in hemodynamic parameters and thermal instability. The populations most vulnerable to this disease are low birth weight newborns exposed to the neonatal intensive care environment. Objectives: This study aimed to identify the profile of newborns and maternal and neonatal factors associated with the occurrence of deaths from necrotizing enterocolitis in a reference maternity hospital in Ceará, Brazil. Methodology: This is a retrospective cohort study seeking to describe the incidence ofa particular event over time, as well as establish causal relationships between the factors associated with the event. The study population comprised newborns who died from necrotizing enterocolitis between 2019 and 2021, who had neonatal death investigation forms filled out correctly, with no newborns being excluded, totaling a sample of 29 deaths. Results: It was identified that the profile of newborns was mostly premature, of low birth weight and with risk factors for other associated diseases such as sepsis, leading to invasive procedures and hospitalization in a neonatal intensive care environment. Conclusions: Prematurity and low birth weight were relevant variables in the study and may be associated with worsening of the newborn's clinical conditionsand development of necrotizing enterocolitis (AU).

ABSTRACT

Abstract Objectives To evaluate if there are differences regarding disease location and mortality of necrotizing enterocolitis, according to the gestational age at birth, in newborns submitted to surgery due to enterocolite. Methods A historical cohort study of 198 newborns submitted to surgery due to necrotizing enterecolitis in a tertiary hospital, from November 1991 to December 2012. The newborns were divided into different categories according to gestational age (<30 weeks, 30-33 weeks and 6 days, 34-36 weeks and 6 days, and ≥37 weeks), and were followed for 60 days after surgery. The inclusion criterion was the presence of histological findings of necrotizing enterocolitis in the pathology. Patients with single intestinal perforation were excluded. Results The jejunum was the most commonly affected site in extremely premature infants (p = 0.01), whereas the ileum was the most commonly affected site in premature infants (p = 0.002), and the colon in infants born at term (p < 0.001). With the increasing gestational age, it was observed that intestinal involvement decreased for the ileum and the jejunum (decreasing from 45% to 0% and from 5% to 0%, respectively), with a progressive increase in colon involvement (0% to 84%). Total mortality rate was 45.5%, and no statistical difference was observed in the mortality at different gestational ages (p = 0.287). Conclusions In newborns submitted to surgery due to necrotizing enterocolitis, the disease in extremely preterm infants was more common in the jejunum, whereas in preterm infants, the most affected site was the ileum, and in newborns born close to term, it was the colon. No difference in mortality was observed according to the gestational age at birth.


Resumo Objetivos Avaliar se há diferença de localização e de mortalidade da enterocolite necrosante de acordo com a idade gestacional ao nascimento, em neonatos operados por enterocolite. Métodos Coorte histórica de 198 neonatos operados por enterocolite necrosante em hospital terciário, de novembro de 1991 a dezembro de 2012. Os recém-nascidos operados foram divididos em diferentes categorias de acordo com a idade gestacional (< 30 semanas, 30 a 33 semanas e seis dias, 34 a 36 semanas e seis dias e ≥ 37 semanas) e foram seguidos por 60 dias depois da cirurgia. O critério de inclusão foi a presença de achados histológicos de enterocolite necrosante no anatomopatológico e o de exclusão foi a presença de perfuração intestinal única. Resultados O jejuno foi mais acometido pela ECN nos prematuros extremos (p = 0,01); o íleo mais afetado nos recém-nascidos prematuros (p = 0,002) e o cólon nos recém-nascidos a termo ou próximos ao termo (p < 0,001). Com o aumento da idade gestacional, observam-se redução do acometimento do jejuno e do íleo (regrediu de 45% para 0% e de 5% para 0%, respectivamente) e aumento progressivo do acometimento do cólon (0% para 84%). A mortalidade total das crianças operadas por ECN foi de 45,5%; não existiu diferença estatística na mortalidade nas diferentes idades gestacionais (p = 0,287). Conclusões Em recém-nascidos operados por enterocolite necrosante, a doença no jejuno foi mais comum no prematuro extremo, no íleo no prematuro, e a doença no cólon nos recém-nascidos próximos ao termo. Não foi observada diferença de mortalidade de acordo com a idade gestacional ao nascimento.

ABSTRACT

Abstract Purpose: To evaluate the effect of remote ischemic preconditioning (r-IPC) administered to pregnant rats, in the ileum of newborn rats subjected to hypoxia and reoxygenation. Methods: We used three pregnant rats and their newborn rats distributed in three groups: 1) Control (C) - Newborn rats born from a pregnant rat which did not undergo any intervention; 2) Hypoxia-Reoxygenation (H/R) - Newborn rats born from a pregnant rat which did not undergo any intervention, and were subjected to hypoxia-reoxygenation; 3) Remote Ischemic Preconditioning (r-IPC) - newborn rats born from a pregnant rat which was subjected to remote ischemic preconditioning twenty-four hours before giving birth and the newborn rats were subjected to hypoxia-reoxygenation. Segments of ileum were prepared for histological analysis by HE and immunohistochemistry by the Ki67 to evaluate cell proliferation, crypt depth and villus height and evaluation of apoptosis by cleaved caspase-3. Results: The intensity of the lesions was lower in the r-IPC than in the H/R group, showing significant difference (p<0.01). The r-IPC group showed a higher proliferative activity compared to the H/R group (p<0.01), with deeper crypts (r-IPC > H/R - p < 0.05), and higher villi, showing significant difference (r-IPC > H/R - (p <0.01). The occurrence of apoptosis in the H/R group was lower in comparison to groups C and r-IPC, with significant difference (H/R < r-IPC; p<0.05). Conclusion: The remote ischemic preconditioning applied to the pregnant rat protected the ileum of newborn rats subjected to hypoxia and reoxygenation, with decreased intensity of the lesions in the ileum mucosa and preservation of proliferative activity, keeping the villus height and crypt depth similar to group C.

ABSTRACT

OBJECTIVES: Necrotizing enterocolitis is a severe multifactorial intestinal disorder that primarily affects preterm newborns, causing 20-40% mortality and morbidity. Intestinal fatty acid-binding protein has been reported to be a biomarker for the detection of intestinal injuries. Our aim was to assess intestinal tissue injury and the molecular expression of intestinal fatty acid-binding protein over time in a necrotizing enterocolitis model. METHODS: A total of 144 Newborn rats were divided into two groups: 1) Control, which received breastfeeding (n=72) and 2) Necrotizing Enterocolitis, which received formula feeding and underwent hypoxia and hypothermia (n=72). A total of six time points of ischemia (2 times a day for 3 days; 12 pups for each time point) were examined. Samples were collected for analysis of body weight, morphological and histological characteristics, intestinal weight, intestinal weight/body weight ratio, injury grade, and intestinal fatty acid-binding protein levels. RESULTS: Body and intestinal weights were lower in the Necrotizing Enterocolitis group than in the Control group (p<0.005 and p<0.0005, respectively). The intestinal weight/body weight ratio was higher in the Necrotizing Enterocolitis group than in the Control group (p<0.005) only at the sixth ischemia time point. The Necrotizing Enterocolitis group displayed higher expression of intestinal fatty acid-binding protein (p<0.0005) and showed greater tissue damage than the Control group. CONCLUSION: Intestinal fatty acid-binding protein was an efficient marker of ischemic injury to the intestine and a good correlation was demonstrated between the time of ischemic injury and the grade of intestinal injury.

ABSTRACT

Objective: An unclear issue is whether gender may influence at cardiac remodeling after myocardial infarction (MI). We evaluated left ventricle remodeling in female and male rats post-MI. Methods: Rats were submitted to anterior descending coronary occlusion. Echocardiographic evaluations were performed on the first and sixth week post-occlusion to determine myocardial infarction size and left ventricle systolic function (FAC, fractional area change). Pulsed Doppler was applied to analyze left ventricle diastolic function using the following parameters: E wave, A wave, E/A ratio. Two-way ANOVA was applied for comparisons, complemented by the Bonferroni test. A P≤=0.05 was considered significant. Results: There were no significant differences between genders for morphometric parameters on first (MI [Female (FE): 44.0±5.0 vs. Male (MA): 42.0±3.0%]; diastolic [FE: 0.04±0.003 vs. MA: 0.037±0.005, mm/g] and systolic [FE: 0.03±0.0004 vs. MA: 0.028±0.005, mm/g] diameters of left ventricle) and sixth (MI [FE: 44.0±5.0 vs. MA: 42.0±3.0, %]; diastolic [FE: 0.043±0.01 vs. MA: 0.034±0.005, mm/g] and systolic [FE: 0.035±0.01 vs. MA: 0.027±0.005, mm/g] of LV) week. Similar findings were reported for left ventricle functional parameters on first (FAC [FE: 34.0±6.0 vs. MA: 32.0±4.0, %]; wave E [FE: 70.0±18.0 vs. MA: 73.0±14.0, cm/s]; wave A [FE: 20.0±12.0 vs. MA: 28.0±13.0, cm/s]; E/A [FE: 4.9±3.4 vs. MA: 3.3±1.8]) and sixth (FAC [FE: 29.0±7.0 vs. MA: 31.0±7.0, %]; wave E [FE: 85.0±18.0 vs. MA: 87.0±20.0, cm/s]; wave A [FE: 20.0±11.0 vs. MA: 28.0±17.0, cm/s]; E/A [FE: 6.2±4.0 vs. MA: 4.6±3.4]) week. Conclusion: Gender does not influence left ventricle remodeling post-MI in rats. .


Objetivo: A influência do gênero no remodelamento cardíaco após o infarto do miocárdio é uma questão em intenso debate. Nós avaliamos o remodelamento ventricular esquerdo em ratos infartados de ambos os gêneros. Métodos: O infarto do miocárdio foi induzido por oclusão da artéria coronária descendente anterior (fêmeas [FM]; machos [MC]). A ecocardiografia foi realizada na primeira e sexta semana pós-oclusão para determinar o tamanho do infarto do miocárdio e a função sistólica do ventricular esquerdo (mudança na área fracional [FAC]). A função diastólica derivou dos seguintes parâmetros: onda E; onda A; razão E/A. ANOVA duas vias com pós-teste de Bonferroni foi aplicado nas comparações (P≤=0,05). Resultados: Todas variáveis morfométricas foram similares (P>0,05) entre os gêneros com uma (infarto do miocárdio [FM: 44,0±5,0 vs. MC: 42,0±3,0, %]; diâmetro diastólico [FM: 0,04±0,003 vs. MC: 0,037±0,005, mm/g] e sistólico [FM: 0,03±0,0004 vs. MC: 0,028±0,005, mm/g] do VE) e seis (IM [FM: 44,0±5,0 vs. MC: 42,0±3,0, %]; diâmetro diastólico [FM: 0,043±0,01 vs. MC: 0,034±0,005, mm/g] e sistólico [FM: 0,035±0,01 vs. MC: 0,027±0,005, mm/g] do ventricular esquerdo) semanas. Achado similar ocorreu para os dados funcionais com uma (FAC [FM: 34,0±6,0 vs. MC: 32,0±4,0, %]; onda E [FM: 70,0±18,0 vs. MC: 73,0±14,0, cm/s]; onda A [FM: 20,0±12,0 vs. MC: 28,0±13,0, cm/s]; E/A [FM: 4,9±3,4 vs. MC: 3,3±1,8]) e seis (FAC [FM: 29,0±7,0 vs. MC: 31,0±7,0, %]; onda E [FM: 85,0±18,0 vs. MC: 87,0±20,0, cm/s]; onda A [FM: 20,0±11,0 vs. MC: 28,0±17,0 cm/s]; E/A [FM: 6,2±4,0 vs. MC: 4,6±3,4]) semanas. Conclusão: O gênero não é determinante para o remodelamento ventricular esquerdo pós-infarto do miocárdio em ratos. .

ABSTRACT

PURPOSE: To evaluate the effects of maternal remote ischemic preconditioning (IPCr) in the colonic mucosa of newborn rats subjected to hypoxia and reoxygenation. METHODS: Newborn Wistar rats were divided into three groups. Control Group (CG), Hypoxia and Reoxygenation Group (HRG) and Remote Ischemic Preconditioning Group (IPCrG). Hypoxia and reoxygenation was performed 2x per day, with an interval of 6 hours, on the 1st, 2nd and 3rd days of life, with 10 minutes of CO2 at 100%, followed by 10 minutes O2 at 100%(HRG/IPCrG). The maternal IPCr was performed 24 hours before delivery by applying a rubber band tourniquet to the left hind limb (IPCrG). Segments of the colon underwent histological (HE) and immunohistochemical analysis for caspase-3 and COX - 2. RESULTS: The histological findings showed no intestinal mucosal damage in the CG group and severe lesions in HRG that was attenuated in the IPCrG (p<0.05). The expression of the apoptotic cells was lower in the HRG group than in the CG and IPCrG. The COX-2 expression was intense in HRG and attenuated in the IPCrG (p<0.05). CONCLUSIONS: Maternal IPCr protected the colonic mucosa of newborn rats subjected to hypoxia and reoxygenation, reducing the morphological alterations and inflammatory response. It ameliorates the occurrence of apoptosis, keeping the physiological process of renewal and regeneration in the epithelial lining of the colonic mucosa. .

ABSTRACT

PURPOSE: To determine the expression of hepatic L-FABP and intestinal I-FABP in an experimental model of necrotizing enterocolitis (NEC) in neonatal rats. METHODS: Newborn Sprague-Dawley rats were divided into four groups: Control (C1) - exclusive breastfeeding at the first and sixth procedures (C6), NEC1 - fed formula milk and submitted to hypoxia and hypothermia at the first and sixth procedures (NEC6). The newborn pups were fed twice a day for three days, for a total of six procedures. Samples were collected for morphometric evaluation (body weight, liver weight, liver weight/body weight ratio, intestinal weight and intestinal/body weight ratio) and for immunohistochemical and Western blotting analysis. The values obtained were analyzed statistically, with the level of significance set at p<0.05. RESULTS: Morphometric measurements showed reduction of body and liver weights in the NEC group (p<0.05). Both immunohistochemistry and western blotting revealed that L-FABP expression in the liver was decreased and I-FABP expression in the ileum was increased in the NEC group (p<0.05). CONCLUSION: L-FABP and I-FABP expression changed inversely in the rat NEC model. These findings can contribute to a better diagnosis of NEC in human newborns. .

ABSTRACT

Pneumatosis intestinalis in newly born infants constitutes a clinical manifestation greatly associated with the presence of necrotizing enterocolitis, a highly severe medical condition. This study provides a clinical case series presenting with bloody stools and benign pneumatosis intestinalis. A short colonoscopy proven diagnosis of allergic colitis was made, which was confirmed in the 87,5 percent (7/8) of the cases, while a number of biopsies showed eosinophiles exceeding the normal ranges. Diagnosis in 12,5 percent of patients (1/8) was based on clinical records, lab-tests, imaging and treatment responses. The suppression of cow's milk protein in the maternal diet or the replacement of human milk by a substitute free from that protein led to a rapid regression of symptomatology.


La neumatosis intestinal en el recién nacido es un signo que se asocia mayoritariamente a la presencia de enterocolitis necrotizante, una condición grave. Se presenta una serie de casos clínicos que debutaron con sangre en la deposición y neumatosis intestinal de curso benigno, diagnosticándose una colitis alérgica, que fue demostrada en el 87,5 por ciento (7/8) de los casos mediante colonoscopía corta y biopsias que demostraron un número de eosinófilos mayor que lo normal; en el 12,5 por ciento (1/8) el diagnóstico se basó en clínica, laboratorio, imágenes y respuesta a tratamiento. La supresión de la proteína de la leche de vaca en la dieta de la madre o el reemplazo de la leche materna por un sustituto libre de esta proteína, llevó a una rápida regresión de la sintomatología.

ABSTRACT

OBJETIVO: Avaliar o valor prognóstico da distensão de alças intestinais observada em radiografias na evolução e mortalidade de neonatos com enterocolite necrosante. MATERIAIS E MÉTODOS: Nas radiografias de abdome de 53 pacientes obtidas no momento da suspeita diagnóstica de enterocolite necrosante, foi realizada a medida do diâmetro da alça mais distendida (AD), assim como a distância entre a borda superior da primeira vértebra lombar e a borda inferior da segunda (L1-L2), a distância entre as bordas laterais dos pedículos da primeira vértebra lombar (L1), e foram estabelecidas as associações entre AD/L1-L2 e AD/L1. Esta medida foi considerada como possível determinante de potenciais complicações, intervenção cirúrgica e mortalidade. RESULTADOS: Os pacientes que necessitaram de tratamento cirúrgico, aqueles que tiveram complicações durante a evolução e aqueles que morreram da doença tiveram a relação entre AD e AD/L1-L2 maiores (p < 0,05). Os valores de AD/L1 e a localização da alça mais distendida não foram diferentes nos grupos com evolução desfavorável. CONCLUSÃO: Distensão de alça intestinal detectada em radiografias de abdome realizadas na admissão sugerem pior prognóstico em enterocolite necrosante. Outrossim, medidas do diâmetro da alça mais distendida nessas radiografias são um método simples e reprodutível que oferece informações diagnósticas e prognósticas.


OBJECTIVE: To evaluate the prognostic value of bowel loops dilatation as a finding on radiographs in the development and mortality of neonates with necrotizing enterocolitis. MATERIALS AND METHODS: On abdominal radiographs of 53 patients for diagnostic suspicion of necrotizing enterocolitis, the major diameters of dilated bowel loops (AD) were measured, as well as the distance between the upper border of the first lumbar vertebra and the lower border of the second one (L1-L2), and the distance between the lateral borders of the first lumbar vertebra (L1) pedicles, and the subsequent association between AD/L1-L2, AD/L1. This measure was considered as a possible determining factor for potential complications, surgical intervention and mortality. RESULTS: The patients who needed surgical management and who had complications during progression and died of the disease had showed increased AD and AD/L1-L2 (p < 0.05). AD/L1 values and site of the most dilated bowel loop were not different in the groups with unfavorable progression. CONCLUSION: Bowel loop dilatation detected on initial supine abdominal radiographs suggests a worst prognosis in necrotizing enterocolitis. Furthermore, measurement of the most dilated bowel loop on these radiographs is a simple and reproducible method that adds diagnostic and prognostic information.

ABSTRACT

OBJETIVO: Avaliar um modelo experimental de enterocolite necrosante em ratos proposto por Okur e colaboradores em 1995. MÉTODOS: Utilizou-se 28 ratos da raça EPM-Wistar no primeiro dia de vida, com peso entre 4 a 6 gramas. Os animais foram submetidos a hipóxia (H) colocando os filhotes em uma câmara de gás CO2 para sacrifício de roedores onde receberam um fluxo de ar contendo 100 por cento de CO2 durante 5 minutos. Após a hipóxia os animais foram reanimados (R) com fluxo de ar contendo O2 a 100 por cento, também durante 5 minutos. Os animais divididos em dois grupos: G1: controle (n=12): ratos não submetidos a H-R; G2: (n=16): ratos submetidos a H-R. Segmentos de intestino delgado e cólon foram preparados para análise histológica. O restante do intestino foi utilizado para dosagem de malondialdeído tecidual. RESULTADOS: Dosagem de malondialdeído do G1 foi em média 1,05 (0,44-2,03) e do G2 foi em média 2,60 (0,59- 6,4) nmol MDA/mg proteína. O G2 teve média significativamente maior do que a do grupo controle (p<0,002). Foi encontrada diferença estatisticamente significante entre os grupos de estudo quanto à distribuição do grau de lesão onde o grupo G1 apresentou graus significantemente menores do que o grupo G2. CONCLUSÕES: O modelo mostrou que a hipóxia neonatal em ratos provoca lesões na parede intestinal.. Apesar das lesões histológicas discretas é um bom método para avaliação da liberação de radicais livres teciduais.

A enterite necrosante é uma doença típica do período neo-natal que pode acometer o intestino delgado, colo e/ou estômago. Até o presente, a necrose maciça do intestino delgado com o acometimento concomitante do esôfago nunca foi relatada. É apresentado o caso de um lactente com 6 meses de idade com enterite necrosante e acometimento de todo intestino delgado, ceco e terço inferior do esôfago. Após setenta dias de tratamento, o trânsito intestinal foi re-estabelecido por anastomose entre o primeiro centímetro do jejuno e o colo ascendente. Finalmente, o trânsito esofagiano foi refeito pela transposição gástrica total e anastomose esôfago-gástrica cervical. O paciente foi mantido em nutrição parenteral durante 19 meses e ao fim deste período desenvolveu falência hepática aguda, tendo sido submetido a transplante duplo de fígado e intestino delgado. Dois meses após, faleceu em decorrência de complicações neurológicas, provavelmente relacionadas à infecção ou ao tratamento imunossupressor.

ABSTRACT

Com o objetivo de fornecer subsídios para o estudo da patologia, os autores relatam e discutem um caso de Enterocolite Necrosante Neo-Natal (ECN) que culminou com perfuração intestinal (estadio III-B de Bell modificado), ocorrido num recém-nascido pré-termo. Os sinais clínicos de ECN - resíduos alimentar, distensão abdominal e vômito fecalóide - iniciaram com cerca de 85 h de vida; no 5§ dia evidenciou-se edema e hiperemia de parede abdominal e resistência à palpação e, no 6§ dia, a radiodrafia de abdome revelou pneumoperitônio. Submetido a laparotomia, tendo sido ressecados cerca de 30 cm de intestino (íleo e parte do colo ascendente) necrosado e realizada enterostomia. Permaneceu vários dias em UTI, recebendo tratamento à base de antibióticos, sangue, plasma fresco, imunoglobulina endovenosa e alimentação parenteral. Aos 6 meses de idade foi realizada a cirurgia para restabelecer o trânsito intestinal anatômico, que transcorreu sem anormalidades. Os autores concluíram que a abordagem cirúrgica aliada ao criterioso controle clínico, propiciou excelente resultado no tratamento de uma forma grave de ECN (estadio III-B de Bell) numa rn pré-termo
