RESUMEN
Introduction: Neonatal sepsis is a condition that carries a high risk for mortality as neonates rapidly transition to extra-uterine life and are subjected to various risk factors. Sepsis prevalence can be reduced by good antenatal care, early detection and treatment of risk factors. The study aimed to find out the prevalence of sepsis among neonates admitted to a neonatal intensive care unit in a tertiary care centre. Methods: This is a descriptive cross-sectional study conducted among neonates admitted to the neonatal care unit of a tertiary care centre after obtaining ethical approval from the Institutional Review Committee. Data of patients admitted from 12 December 2022 to 30 June 2023 was collected from hospital records. Symptomatic patients admitted to the neonatal intensive care unit were included and those with incomplete data were excluded from the study. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 379 neonates, the prevalence of sepsis was 138 (36.41%) (28.38-44.44, 95% Confidence Interval). A total of 98 (71.01%) had early-onset neonatal sepsis and 40 (28.99%) had late-onset neonatal sepsis. Conclusions: The prevalence of neonatal sepsis was found to be lower than other studies done in similar settings. Keywords: neonate; neonatal sepsis; prematurity; prevalence.

OBJECTIVE: To evaluate the efficiency of the sepsis risk calculator and the serial clinical observation in the management of late preterm and term newborns with infectious risk factors. METHOD: Single-center, observational, two-phase cohort study comparing the rates of neonates born ≥35 weeks' gestation, ≥2000 g birthweight, and without major congenital anomalies, who were screened and/or received antibiotics for early-onset neonatal sepsis risk at our center during two periods, before (January/2018-June/2019) and after (July/2019-December/2020) the implementation of the sepsis risk calculator. RESULTS: A total of 1796 (Period 1) and 1867 (Period 2) patients with infectious risk factors were included. During the second period, tests to rule out sepsis were reduced by 34.0 % (RR, 95 %CI): 0.66 (0.61, 0.71), blood cultures by 13.1 %: 0.87 (0.77, 0.98), hospital admissions by 13.5 %: 0.86 (0.76, 0.98) and antibiotic administration by 45.9 %: 0.54 (0.47, 0.63). Three cases of early-onset neonatal sepsis occurred in the first period and two in the second. Clinical serial evaluation would have detected all true cases. CONCLUSIONS: The implementation of a sepsis risk calculator in the management of newborns ≥35 weeks GA, ≥2000 g birthweight, without major congenital anomalies, with infectious risk factors is safe and adequate to reduce laboratory tests, blood cultures, hospital admissions, and antibiotics administration. Serial clinical observation, in addition, could be instrumental to achieve or even improve this goal.

BACKGROUND: Neonatal bacterial infections have long been recognized as an important cause of acute morbidity and mortality, but long-term neurodevelopmental consequences have not been comprehensively described and discussed. OBJECTIVES: We aimed to summarize evidence on the pathogenesis, diagnosis, and epidemiology of long-term sequelae after neonatal bacterial sepsis and meningitis. We also discuss approaches for future studies to quantify the public health impact of neonatal infection-associated neurodevelopmental impairment. SOURCES: We identified studies, both research articles and reviews, which provide mechanistic information on the long-term disease, as well as epidemiological studies that describe the frequency of neurodevelopmental impairment in children with and, for comparison, without a history of neonatal bacterial infection. Tools currently used in clinical practice and research settings to assess neurodevelopmental impairment were also reviewed. CONTENT: We first enumerate potential direct and indirect mechanisms that can lead to brain injury following neonatal infections. We then discuss summary data, either frequencies or measures of association, from epidemiological studies. Risk factors that predict long-term outcomes are also described. Finally, we describe clinical approaches for identifying children with neurodevelopmental impairment and provide an overview of common diagnostic tools. IMPLICATIONS: The limited number of studies that describe the long-term consequences of neonatal infections, often undertaken in high-income settings and using variable designs and diagnostic tools, are not sufficient to inform clinical practice and policy prioritization. Multi-country studies with follow-up into adolescence, standardized diagnostic approaches, and local comparator groups are needed, especially in low and middle-income countries where the incidence of neonatal sepsis is high.

BACKGROUND: Neonatal sepsis is one of the leading causes of neonatal morbidity and mortality in low- and middle-income countries. Blood culture positivity rates and antibiotic resistance pattern of neonatal sepsis differs across various regions. This study aims to identify clinical cofactors associated with blood culture-proven neonatal sepsis and in vitro resistance to first-line antibiotics (ampicillin and gentamicin) from cases originating in a tertiary healthcare center in Surabaya, Indonesia. METHODS: A retrospective cohort study was conducted from January 2020 to August 2022 by utilizing secondary data collected from standardized electronic medical records. Microbiologic characteristics and associated factors were statistically analyzed using multivariable logistic regression. RESULTS: Across 266 neonatal sepsis cases, 46.9% were culture-proven and 79.2% of confirmed sepsis were resistant to first-line antibiotics. The most common isolated pathogen is Klebsiella pneumoniae , followed by coagulase-negative Staphylococci , Acinetobacter baumannii and Enterobacter cloacae . Extremely preterm delivery [adjusted odds ratio (aOR): 5.813; 95% confidence interval (CI): 1.70-19.91] and late-onset sepsis (aOR: 9.165; 95% CI: 5.12-16.40) were associated with culture-proven neonatal sepsis. Increased odds of resistance to first-line antibiotics were identified in extremely preterm (<28 weeks) or very-preterm delivery (28 to <32 weeks) (aOR: 50.80; 95% CI: 1.66-1554.21 and aOR: 45.679; 95% CI: 3.22-647.46, respectively), cesarean section (aOR: 4.149; 95% CI: 1.04-16.53) and an absence of antenatal corticosteroid use (aOR: 0.233; 95% CI: 0.07-0.76). CONCLUSIONS: The association between clinical cofactors with culture-proven sepsis and antibiotic resistance emphasizes the importance for clinicians to adjust empirical antibiotic regimens based on the local antibiogram and resource availability.

OBJECTIVES: To determine whether maternal colonization with Group B Streptococcus increases the risk for infectious morbidity following transcervical Foley catheter-assisted cervical ripening. METHODS: A retrospective cohort study comparing infectious morbidity and other clinical outcomes by Group B Streptococcus colonization status between all women with singleton pregnancies who underwent Foley catheter-assisted cervical ripening labor induction at a single tertiary medical center during 2011-2021. Multivariable logistic regression explored the relationship between Group B Streptococcus colonization to adverse outcomes while adjusting for relevant clinical variables. RESULTS: A total of 4,409 women were included of whom 886 (20.1â¯%) were considered Group B Streptococcus carriers and 3,523 (79.9â¯%) were not. Suspected neonatal sepsis rate was similar between Group B Streptococcus carriers and non-carriers (5.2 vs. 5.0â¯%, respectively, p=0.78). Neonatal sepsis was confirmed in 7 (0.02â¯%) cases, all born to non-carriers. Group B Streptococcus carriers had a higher rate of maternal bacteremia compared to non-carriers (1.2 vs. 0.5â¯%, respectively, p=0.01). Group B Streptococcus colonization was independently associated with maternal bacteremia (adjusted odds ratio 3.05; 95â¯%CI 1.39, 6.66). CONCLUSIONS: Group B Streptococcus colonization among women undergoing Foley catheter-assisted cervical ripening does not seem to increase the risk for neonatal infection. However, higher rates of maternal bacteremia were detected.

BACKGROUND: Neonatal sepsis is the major cause of neonatal mortality and morbidity, especially in low and middle-income countries. Continuous monitoring of pathogens and their antibiotic resistance pattern is crucial for managing neonatal sepsis. This study aimed to determine neonatal sepsis due to bacteria, antibiotic resistance patterns, associated risk factors and patient outcomes at St. Paul's Hospital Millennium Medical College. METHOD: An institutional-based cross-sectional study was conducted on 400 neonates suspected of sepsis at St. Paul's Hospital Millennium Medical College from March 2020 to July 2020. A questionnaire was used to collect socio-demographic information, clinical parameters and potential risk factors from study participants. About 2ml of blood was drawn aseptically and inoculated into Tryptone Soya Broth at the patient's bedside. Bacterial identification was performed by using standard microbiological techniques. The disk diffusion method was used to determine the antibiotic susceptibility patterns of each isolated bacteria. Data entry and analysis were done using Statistical Package for Social Sciences (SPSS) version 20 software. Bivariate and multivariable logistic regressions were used to assess associated risk factors of neonatal sepsis. A p-value less than 0.05 was considered statically significant with a 95% confidence interval. RESULTS: The overall prevalence of neonatal septicemia was 21% (84/400). Of these, 67 (79.8%) and 17 (20.2%) were gram-negative and gram-positive bacteria, respectively. Klebsiella spp, 37 (44%), E. coli 19 (21.6%) and Coagulase negative Staphylococci 13 (15.47%) were the leading cause of neonatal sepsis. Ciprofloxacin and amikacin were the most effective antibiotics for gram-negative and gram-positive bacteria. Multidrug resistance was observed in 84% of the bacterial isolates. Low birth weight and preterm were associated with neonatal septicemia (AOR = 49.90, 95% CI = 15.14-123.081, P = 0.002) and (AOR = 18.20, 95% CI = 6.835-27.541, P = 0.004) respectively. CONCLUSION: Klebsiella spp and E. coli were frequently isolated bacteria in our study. The proportion of multidrug-resistance was significantly high. Most isolated bacteria were resistant to ampicillin, ceftazidime, cefotaxime and gentamycin, which indicates the necessity of continuous evaluation of antibiotic resistance rate.

OBJECTIVE: Early-onset neonatal sepsis (EONS) remains an important cause of neonatal mortality and has many risk factors, therefore, this study aimed to investigate the perinatal risk factors for EONS. METHODS: We searched CNKI, Wan Fang, VIP, CBM, PubMed, Embase, and Web of Science to compile studies regarding the incidence of neonatal early-onset sepsis, published up to 1 May 2022. To evaluate the quality of the included studies, we used the Newcastle-Ottawa Scale, and the RevMan5.3 software was used for meta-analysis. RESULTS: A total of 17 studies were included, with 1987 cases in the case group and 4814 cases in the control group. Meta-analysis showed that perinatal asphyxia or intrauterine distress (OR = 3.00, 95% CI: 2.18-4.13), amniotic fluid meconium contamination (OR = 4.51, 95% CI: 2.31-8.81), group B streptococcal (GBS) colonization in pregnant women (OR = 2.13, 95% CI: 1.48-3.05), chorioamnionitis (OR = 4.58, 95% CI: 2.61-8.05), premature rupture of membranes (OR = 2.63, 95% CI: 2.09-3.30), lower gestational age (OR = 1.31, 95% CI: 1.18-1.44), maternal urinary or reproductive tract infection (OR = 3.61, 95% CI: 2.14-6.11), perinatal fever (OR = 3.59, 95% CI: 2.25-5.71), very low birth weight (OR = 3.79, 95% CI: 2.14-6.73), and vaginal examination ≥3 times (OR = 7.95, 95% CI: 4.04-15.64) were the perinatal risk factors for EONS. CONCLUSION: Perinatal asphyxia or intrauterine distress, meconium contamination in amniotic fluid, GBS colonization in pregnant women, chorioamnionitis, premature rupture of membranes, lower gestational age, maternal urinary tract or reproductive tract infection, perinatal fever, very low birth weight, and vaginal examinations ≥3 times may increase the risk of EONS.

BACKGROUND: The use of cerebral oximetry monitoring in the care of extremely preterm infants is increasing. However, evidence that its use improves clinical outcomes is lacking. METHODS: In this randomized, phase 3 trial conducted at 70 sites in 17 countries, we assigned extremely preterm infants (gestational age, <28 weeks), within 6 hours after birth, to receive treatment guided by cerebral oximetry monitoring for the first 72 hours after birth or to receive usual care. The primary outcome was a composite of death or severe brain injury on cerebral ultrasonography at 36 weeks' postmenstrual age. Serious adverse events that were assessed were death, severe brain injury, bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, and late-onset sepsis. RESULTS: A total of 1601 infants underwent randomization and 1579 (98.6%) were evaluated for the primary outcome. At 36 weeks' postmenstrual age, death or severe brain injury had occurred in 272 of 772 infants (35.2%) in the cerebral oximetry group, as compared with 274 of 807 infants (34.0%) in the usual-care group (relative risk with cerebral oximetry, 1.03; 95% confidence interval, 0.90 to 1.18; P = 0.64). The incidence of serious adverse events did not differ between the two groups. CONCLUSIONS: In extremely preterm infants, treatment guided by cerebral oximetry monitoring for the first 72 hours after birth was not associated with a lower incidence of death or severe brain injury at 36 weeks' postmenstrual age than usual care.

Background: Despite growing evidence, there is still uncertainty about potentially modifiable risk factors for neonatal early-onset sepsis (EOS). This study aimed to identify potential clinical risk factors for EOS based on a literature review and expert opinions. Methods: A literature search was conducted in PubMed (MEDLINE), Cochrane, Embase, and Scopus databases. Articles in English, published up to May 2021, on clinical risk factors for neonatal EOS were included. Initially, a questionnaire on risk factors for EOS was developed and validated. The fuzzy Delphi method (FDM) was used to formulate the final version of the questionnaire. The validity of the risk factors was assessed using the Chi square test. P<0.05 was considered statistically significant. Results: In the review phase, 30 risk factors were approved by two neonatologists and included in the FDM phase. In total, 25 risk factors met the consensus criteria and entered the validation phase. During the observational study, 114 neonates (31 with and 83 without EOS) were evaluated for two months. The results of the Chi square test showed that cesarean section was not a significant risk factor for EOS (P=0.862). The need for mechanical ventilation and feed intolerance was observed in about 70% of neonates with EOS, and therefore considered significant risk factors for EOS (P<0.001). Finally, 26 potential clinical risk factors were determined. Conclusion: Neonatal-related risk factors for EOS were birth weight, one-min Apgar score, and prematurity. Maternal-related risk factors were gestational age and urinary tract infection. Delivery-related risk factors were premature rupture of membranes, chorioamnionitis, and intrapartum fever.

Neonatal sepsis is a systemic infection that occurs at an early age. Its etiology varies from one region to the other. The contribution of sepsis to neonatal mortality and morbidity is significant in resource-limited countries; however, there is limited information about the etiology of sepsis in Sidama Regional State, Ethiopia. The aim of this study was to determine the prevalence of bacterial caused newborn sepsis, associated factors, and the antimicrobial susceptibility profile of bacteria. A hospital-based prospective cross-sectional study was conducted among 392 sepsis suspected newborns admitted to the neonatal intensive care unit of Hawassa University Comprehensive Specialized Hospital from March 2021 to November 2021. Blood specimens were collected and bacteria were isolated using the standard culture method. The drug resistance profile of bacteria was evaluated using the disk diffusion method. The socio-demographic and clinical parameters of participants were gathered using a questionnaire. Binary logistic regression was used to determine the determinants of sepsis. A variable with a p < 0.05 was considered a significant determinant of neonatal sepsis with a 95% confidence level. The prevalence of sepsis caused by bacteria among newborns was 143 (36.5%); 95% CI (31.3-41.4). The predominant bacteria was Klebsiella species (n = 61; 42.65%), followed by non-lactose fermenting Gram-negative bacteria (n = 27; 18.88%) and Enterococcus species (n = 26; 18.18%). The overall proportions of antimicrobial resistance of Gram-negative bacteria range from 10.2 to 99.1%. All Klebsiella species were resistant to ceftriaxone. Ppremature rupture of membrane [AOR = 12.7 (95% CI 6.430-25.106)], absence of respiratory support [AOR = 3.53 (95% CI 1.840-6.759)], sex of newborns [AOR = 2.10 (1.214-3.560)] and reason for admission [AOR = 3.17 (95% CI 1.278-7.859)] were significantly associated with culture-confirmed neonatal sepsis. This study indicated the contribution of bacteria in causing sepsis among newborns; the majority of them were Gram-negative bacteria. Most recovered bacteria were resistant to commonly used antibiotics. Pre-term, mode of delivery and types of respiratory support were significantly associated with the occurrence of sepsis caused by bacteria.

OBJECTIVES: To investigate the changes in the pathogen spectrum and antimicrobial resistance over time in neonatal sepsis. METHODS: The medical data were collected from the neonates who were diagnosed with sepsis in the Second Xiangya Hospital of Central South University from January 2010 to December 2019. The incidence rate of sepsis, the pathogen spectrum, and the characteristics of antimicrobial resistance were analyzed. RESULTS: The incidence rate of neonatal sepsis was 4.02% (447/11 111). The top four pathogens detected were coagulase-negative staphylococci (CoNS), Klebsiella pneumoniae, Escherichia coli, and Candida. The incidence rate of sepsis and the pathogen spectrum showed no significant changes over time. Klebsiella pneumoniae was the most frequent pathogen in preterm infants, very low birth weight infants, and small-for-gestational-age infants, accounting for 33.9%, 29.5%, and 42.5%, respectively. CoNS, Klebsiella pneumoniae, and Escherichia coli had a high resistance rate to penicillins and third-generation cephalosporins. CONCLUSIONS: The incidence of neonatal sepsis is high, and the main pathogen is CoNS. The pathogens of neonatal sepsis have a high resistance rate to penicillins and third-generation cephalosporins. It is recommended to enhance the prevention and control of neonatal infection, strengthen the surveillance of pathogens, and further standardize the rational use of antibiotics.

The purpose of this study is to clarify the relationship between neonatal sepsis and future development of Kawasaki disease (KD). We analyzed data from the National Hospital Organization Neonatal Intensive Care Unit (NHO-NICU) registry study in Japan. Participants in this study were children with a history of hospitalization in the NICU at the participating institutions from 2010 to 2014. A questionnaire was administered at age 3 years to obtain information about the patient's history of KD. There were 8275 infants who were eligible for this study. At 3 years of age, parents of 2161 children responded to the follow-up survey (follow-up rate, 26.1%). Multivariate logistic regression analysis adjusted for preterm birth, sex, use of antibiotics in the NICU, parity, and maternal smoking showed that children with neonatal sepsis were more likely to have a history of KD at 3 years of age (adjusted odds ratio [aOR]: 11.67, 95% confidence interval [CI]: 2.84-47.96). CONCLUSIONS: Among infants admitted to the NICU, neonatal sepsis might be associated with development of KD later in life. Further large studies are needed to elucidate the relationship between neonatal infections and KD development. WHAT IS KNOWN: ⢠Preterm birth is known to be a risk factor for Kawasaki disease. â¢It is not yet known which factors related to preterm birth increase the risk of developing Kawasaki disease. WHAT IS NEW: â¢Neonatal sepsis is associated with an increased risk of subsequent development of Kawasaki disease. â¢Antibiotic use in the neonatal intensive care unit may also be an independent risk factor for subsequent development of Kawasaki disease.

OBJECTIVES: To investigate association between latency after preterm premature rupture of membranes (PPROM) and perinatal outcomes at moderately and late preterm gestation. METHODS: National perinatal registry-based cohort study using data for the period 2013-2018. Singleton pregnancies with non-malformed fetuses in cephalic presentation complicated by PPROM at 32+0-36+6 weeks were included. Associations between latency period and perinatal mortality, neonatal respiratory distress syndrome (RDS), early onset neonatal infection (EONI), and cesarean section were assessed using multiple logistic regression, adjusting for potential confounders (labor induction, maternal body-mass-index, maternal age, antenatal corticosteroids, and small-for-gestational-age). p<0.05 was considered statistically significant. RESULTS: Of 3,017 pregnancies included, 365 (12.1%) had PPROM at 32+0-33+6 weeks and 2,652 (87.9%) at 34+0-36+6 weeks. Among all cases, 2,540 (84%) had latency <24 h (group A), 305 (10%) 24-47 h (group B), and 172 (6%) ≥48 h (group C). Longer latency was associated with higher incidence of EONI (adjusted odds ratio [aOR] 1.350; 95% confidence interval [CI] 0.900-2.026 for group B and aOR 2.500; 95% CI 1.599-3.911 for group C) and higher rate of caesarean section (aOR 2.465; 95% CI 1.763-3.447 for group B and aOR 1.854; 95% CI 1.172-2.932 for group C). Longer latency was not associated with rates of RDS (aOR 1.160; 95% CI 0.670-2.007 for group B and aOR 0.917; 95% CI 0.428-1.966 for group C). CONCLUSIONS: In moderately to late PPROM, increased latency is associated with higher risk of EONI and cesarean section with no reduction in RDS.

OBJECTIVE: To evaluate the regional etiology, antimicrobial resistance (AMR) pattern, and risk factors in neonates with sepsis in China. METHODS: We performed a systematic review and meta-analysis by searching Medline, Embase, Scopus, and Web of Science in December 2020. Studies of neonatal sepsis from China published between 2011 and 2020 were included. We pooled the proportion of pathogens and calculated the odds ratios of risk factors with 95% CIs using a random-effects model. RESULTS: We included 29 studies of 164,750 neonates with sepsis. The studies comprise data from 1990 to 2019. Coagulase-negative staphylococci (CoNS), Escherichia coli and Klebsiella spp accounted for 33% (95% CI 24-43), 17% (13-20), and 14% (11-17), respectively. Group B streptococcus (GBS) was the predominant isolate in early-onset sepsis (EOS) (21%, 95% CI 10-31), while the proportion of CoNS was the largest in late-onset sepsis (LOS) (32%, 95% CI 22-43). Resistance of CoNS to penicillin was found in 95% (95% CI 92-98) of 511 cases and Klebsiella spp to ampicillin in 95% (95% CI 90-99) of 364 cases. Maternal underlying diseases (2.61, 95% CI 1.48-4.61), mechanical ventilation (2.41, 1.37-4.23), central venous catheter placement (2.74, 1.77-4.26), peripherally inserted central catheter (PICC) placement (4.26, 2.80-6.49), multiple antibiotic uses (5.35, 1.85-15.43) and total parenteral nutrition (7.96, 2.04-31.02) were risk factors of neonatal sepsis. CONCLUSION: CoNS, E. coli, and Klebsiella spp were the predominant pathogens in neonatal sepsis in China. AMR was still a significant issue in NICUs. Total parenteral nutrition, multiple antibiotic uses, and PICC placement were the most relevant risk factors.

Diagnostic tests for sepsis aim to either detect the infectious agent (such as microbiological cultures) or detect host markers that commonly change in response to an infection (such as C-reactive protein). The latter category of tests has advantages compared to culture-based methods, including a quick turnaround time and in some cases lower requirements for blood samples. They also provide information on the immune response of the host, a critical determinant of clinical outcome. However, they do not always differentiate nonspecific host inflammation from true infection and can inadvertently lead to antibiotic overuse. Multiple noninfectious conditions unique to neonates in the first days after birth can lead to inflammatory marker profiles that mimic those seen among infected infants. Our goal was to review noninfectious conditions and patient characteristics that alter host inflammatory markers commonly used for the diagnosis of early-onset sepsis. Recognizing these conditions can focus the use of biomarkers on patients most likely to benefit while avoiding scenarios that promote false positives. We highlight approaches that may improve biomarker performance and emphasize the need to use patient outcomes, in addition to conventional diagnostic performance analysis, to establish clinical utility.

Introducción: el estreptococo del grupo B (EGB) es una causa frecuente de sepsis neonatal. La enfermedad precoz disminuyó su incidencia por la profilaxis antibiótica, a diferencia de la sepsis tardía, que aumentó su incidencia en los últimos años. Objetivo: conocer la incidencia de la sepsis tardía en el período 2016-2017 en el Centro Hospitalario Pereira Rossell (CHPR). El secundario, describir las características epidemiológicas y clínicas de sepsis tardía por EGB en niños ingresados a la Unidad de Cuidados Intensivos de Niños (UCIN) del CHPR en el período 2007-2017. Resultados: la incidencia calculada de sepsis tardía por EGB fue de 0,53 casos/1000 recién nacidos (RN) vivos. Entre los años 2007 y 2017 ingresaron cinco niños por sepsis tardía por EGB a la UCIN del CHPR. La presentación clínica más frecuentes fue fiebre sin foco y meningitis. Se obtuvieron tres aislamientos en sangre de EBG y tres en líquido cefalorraquídeo (dos en cultivo y otro por detección de ADN). Ninguno falleció. Los casos con meningitis presentaron alteraciones en la tomografía de cráneo. Un niño fue pretérmino. Conclusiones: la sepsis tardía se vincula a importante morbimortalidad en pediatría. No se ha establecido cuáles son los principales factores de riesgo asociados a una enfermedad grave ni las políticas para disminuir su incidencia.
Background: group B streptococcus (GBS) is a common cause of neonatal sepsis. Early disease decreased its incidence due to antibiotic prophylaxis. Late sepsis increased its incidence in recent years. Objectives: to know the incidence of late onset EGB sepsis in the period 2016-2017 at the Pereira Rossell Hospital Center (CHPR), and secondly, to describe the epidemiological characteristics and the clinical presentation of late onset sepsis due to GBS in children admitted to the Children's Intensive Care Unit (UCIN) of the CHPR in the period 2007-2017. Results: the calculated incidence of late sepsis due to GBS was 0.53 cases/1000 live newborns. Between 2007-2017, 5 children were admitted due to GBS late sepsis at the UCIN. The most frequent clinical presentation was fever without focus and meningitis. 3 isolates were obtained in EBG blood cultures and 3 in cerebrospinal fluid (2 in culture and another by DNA detection). None of them died. Cases with meningitis showed abnormalities in the brain tomography. 1 of the 5 was preterm. Conclusions: late sepsis is associated with significant morbidity and mortality in pediatric patients. The main risk factors associated with serious disease and the policies needed to reduce its incidence have not been established.
Introdução: o estreptococo do grupo B (SGB) é uma causa frequente de sepse neonatal. A doença precoce diminuiu sua incidência devido à profilaxia antibiótica, ao contrário da sepse tardia, que aumentou sua incidência nos últimos anos. Objetivo: conhecer a incidência de sepse tardia no período 2016-2017 no Centro Hospitalar Pereira Rossell (CHPR) e descrever as características epidemiológicas e clínicas da sepse tardia por SGB em crianças internadas na Unidade de Terapia Intensiva Infantil (UTIN) do CHPR no período de 2007-2017. Resultados: a incidência calculada de sepse tardia por SGB foi de 0,53 casos/1000 recém-nascidos vivos (RNs). Entre 2007-2017, 5 crianças foram internadas na UTIN do CHPR por sepse tardia devido a GBS. A apresentação clínica mais frequente foi febre sem causa e meningite. 3 isolados de EBG foram obtidos no sangue e 3 no líquido cefalorraquidiano (2 em cultura e outro por detecção de DNA). Nenhum dos pacientes morreu. Os casos com meningite apresentaram alterações na tomografia de crânio. Uma criança era pré-termo. Conclusões: a sepse tardia está associada a significativa morbimortalidade em pediatria. Os principais fatores de risco associados a uma doença grave e as políticas para reduzir sua incidência ainda não foram estabelecidas.

BACKGROUND: Acute fatty liver of pregnancy (AFLP) and hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome are two uncommon disorders that mimic each other clinically, but are distinct pathophysiologically. This study aimed to compare maternal and neonatal outcomes between AFLP and HELLP syndrome. METHODS: This retrospective cohort study was performed at a tertiary referral center in Taiwan between June 2004 and April 2020. We used the Swansea Criteria to diagnose AFLP, and the Tennessee Classification System to diagnose HELLP syndrome. Maternal characteristics, laboratory data, complications, and neonatal outcomes were compared. We analyzed the categorical variables with Chi-square test or Fisher's exact test and continuous variables with Student's t test or Mann-Whitney U test. Subsequent logistic regression analyses adjusting by potential confounding factors with significant difference were analyzed. RESULTS: During the study period, 21 women had AFLP and 80 women had HELLP syndrome. There was a higher rate of preeclampsia (95.0 % versus 23.8 %) in the HELLP syndrome group compared to the AFLP group. However, the AFLP group had more other maternal complications including jaundice (85.7 % versus 13.8 %), acute kidney injury (61.9 % versus 15.0 %), disseminated intravascular coagulopathy (66.7 % versus 8.8 %), and sepsis (47.6 % versus 10.0 %) compared to the HELLP syndrome group. Nevertheless, higher rates of small for gestational age neonates (57.1 % versus 33.3 %), neonatal respiratory distress syndrome (39.2 % versus 8.3 %) and neonatal sepsis (34.2 % versus 12.5 %) were noted in the HELLP syndrome group. CONCLUSIONS: AFLP is associated with a higher rate of multiple organ dysfunction in mothers, whereas HELLP syndrome is associated with a higher rate of neonatal morbidity.

OBJECTIVES: Clinical chorioamnionitis at term is considered the most common infection-related diagnosis in labor and delivery units worldwide. The syndrome affects 5-12% of all term pregnancies and is a leading cause of maternal morbidity and mortality as well as neonatal death and sepsis. The objectives of this study were to determine the (1) amniotic fluid microbiology using cultivation and molecular microbiologic techniques; (2) diagnostic accuracy of the clinical criteria used to identify patients with intra-amniotic infection; (3) relationship between acute inflammatory lesions of the placenta (maternal and fetal inflammatory responses) and amniotic fluid microbiology and inflammatory markers; and (4) frequency of neonatal bacteremia. METHODS: This retrospective cross-sectional study included 43 women with the diagnosis of clinical chorioamnionitis at term. The presence of microorganisms in the amniotic cavity was determined through the analysis of amniotic fluid samples by cultivation for aerobes, anaerobes, and genital mycoplasmas. A broad-range polymerase chain reaction coupled with electrospray ionization mass spectrometry was also used to detect bacteria, select viruses, and fungi. Intra-amniotic inflammation was defined as an elevated amniotic fluid interleukin-6 (IL-6) concentration ≥2.6 ng/mL. RESULTS: (1) Intra-amniotic infection (defined as the combination of microorganisms detected in amniotic fluid and an elevated IL-6 concentration) was present in 63% (27/43) of cases; (2) the most common microorganisms found in the amniotic fluid samples were Ureaplasma species, followed by Gardnerella vaginalis; (3) sterile intra-amniotic inflammation (elevated IL-6 in amniotic fluid but without detectable microorganisms) was present in 5% (2/43) of cases; (4) 26% of patients with the diagnosis of clinical chorioamnionitis had no evidence of intra-amniotic infection or intra-amniotic inflammation; (5) intra-amniotic infection was more common when the membranes were ruptured than when they were intact (78% [21/27] vs. 38% [6/16]; p=0.01); (6) the traditional criteria for the diagnosis of clinical chorioamnionitis had poor diagnostic performance in identifying proven intra-amniotic infection (overall accuracy, 40-58%); (7) neonatal bacteremia was diagnosed in 4.9% (2/41) of cases; and (8) a fetal inflammatory response defined as the presence of severe acute funisitis was observed in 33% (9/27) of cases. CONCLUSIONS: Clinical chorioamnionitis at term, a syndrome that can result from intra-amniotic infection, was diagnosed in approximately 63% of cases and sterile intra-amniotic inflammation in 5% of cases. However, a substantial number of patients had no evidence of intra-amniotic infection or intra-amniotic inflammation. Evidence of the fetal inflammatory response syndrome was frequently present, but microorganisms were detected in only 4.9% of cases based on cultures of aerobic and anaerobic bacteria in neonatal blood.
