Prolonged empiric antibiotics and time to full enteral feed in preterm infants less than 29 weeks of gestational age

BACKGROUND: Early empiric antibiotic exposure appears to negatively influence feeding tolerance in preterm infants. However, the effect of prolonged antibiotic treatment is unknown. The objective of this study was to investigate whether prolonged antibiotics impact the time to full enteral feed in infants less than 29 weeks of gestational age with negative blood cultures. METHODS: Retrospective data for infants less than 29 weeks gestation age were retrieved from the PEARL-Peristat perinatal registry in Qatar. Exclusion criteria were major congenital anomalies, conditions requiring surgery in the first 10 days of life, positive blood cultures in the first 48 hours of life, and death within the first week of life. Antibiotic courses were categorized as prolonged if continued more than 48 hours. The primary outcome was the duration of total parenteral nutrition. RESULTS: Of 199 study infants, 185 (92.9%) underwent antibiotic treatment for > 48 hours despite negative blood cultures. The median duration of parenteral nutrition was not significantly different between the prolonged and short antibiotic groups (25 and 22 days, respectively; p = 0.139). Infants with prolonged antibiotic courses experienced non-significantly higher levels of necrotizing enterocolitis (7.1% and 18.4%, respectively), bronchopulmonary dysplasia (28.6% and 45.4%, respectively), and retinopathy of prematurity (14.3% and 38.4%, respectively). There were no differences in the late-onset sepsis rate (78.6% and 82.1%, respectively) and the in-hospital death rate (7.1% and 7.6%, respectively). CONCLUSIONS: Prolonged antibiotic treatment in infants less than 29 weeks gestation with negative blood cultures has no significant impact on the time to full enteral feed.

Abstract BackgroundOropharyngeal administration of colostrum (OAC) may provide immunoprotective and anti-inflammatory effects that potentially reduce the incidence of necrotizing enterocolitis (NEC) and late-onset sepsis (LOS) and improve short-term outcomes.ObjectiveTo evaluate the role of OAC in the early prevention of NEC and LOS in preterm infants with gestational age (GA) ≤ 32 weeks.MethodsA randomized, placebo-controlled trial was conducted in a 40-bed tertiary neonatal intensive care unit (NICU) in China. Preterm infants with GA ≤ 32 weeks were divided randomly into an OAC group, which received 0.4 ml maternal colostrum smearing via the oropharyngeal route every 3 hours for 10 days beginning within the first 48 hours after birth, and a control group, which received normal saline instead. Data from the two groups were collected and compared.ResultsA total of 127 patients in the OAC group and 125 patients in the control group were finally enrolled. The incidence of NEC (Bell stage 2 or 3) and LOS was lower in the OAC group [2.4% vs. 10.4%, χ2 = 6.845, ༰=0.009; 4.7% vs. 13.6%, χ2 = 5.983, ༰=0.014]. In addition, the incidence of intraventricular hemorrhage (IVH) (stage 3 or 4) was lower [1.6% vs. 7.2%,χ2 = 4.775, ༰=0.029], and the time of achieving full enteral feeding was shorter [ 22.0 days vs. 25.0 days༌Z = 6༌424.500༌P = 0.009)] in the OAC group. No cases of adverse reactions were observed in either group.ConclusionsOAC is a safe and simple NICU procedure that yields a potential advantage in decreasing the incidence of NEC, LOS, and severe IVH and shortening the time to achieve full enteral feeding in preterm infants with GA ≤ 32 weeks.Trial registrationChinese Clinical Trial Registry, ChiCTR1900023697, Registered 8 June 2019, Retrospectively registered, http://www.chictr.org.cn/edit.aspx? pid = 39398

Probiotic Product

We aimed to evaluate the isolation of strains contained in the Infloran™ probiotic preparation in blood cultures and its efficacy in reducing necrotizing enterocolitis (NEC) and late-onset sepsis (LOS) in extremely preterm infants. Routine use of probiotics was implemented in 2008. Infants born at <28 weeks gestational age were prospectively followed and compared with historical controls (HC) born between 2005 and 2008. Data on sepsis due to any of the two probiotic strains contained in Infloran and rates of LOS and NEC were analysed. A total of 516 infants were included. During the probiotic period (PC), none of the strains included in the administered probiotic product were isolated from blood cultures. Probiotic administration was associated with an increase in NEC stage II or higher (HC 10/170 [5.9%]; PC 46/346 [13.3%]; P=0.010). Surgical NEC was 12.1% in PC (42/346) versus 5.9% (10/170) in HC (P=0.029). Adjusting for confounders (sex, gestational age, antenatal steroids and human milk) did not change those trends (P=0.019). Overall, clinical LOS and the incidence of staphylococcal sepsis were lower in PC (172/342, 50.3, and 37%, respectively) compared with HC (102/169, 60.3 and 50.9%, respectively) (P=0.038 and P=0.003, respectively). No episodes of sepsis attributable to the probiotic product were recorded. The period of probiotic administration was associated with an increased incidence of NEC after adjusting for neonatal factors, but also with a reduction in the LOS rate.

Volatile Organic

Fecal volatile organic compounds (VOC) reflect human and gut microbiota metabolic pathways and their interaction. VOC behold potential as non-invasive preclinical diagnostic biomarkers in various diseases, e.g., necrotizing enterocolitis and late onset sepsis. There is a need for standardization and assessment of the influence of clinical and environmental factors on the VOC outcome before this technique can be applied in clinical practice. The aim of this study was to investigate the influence of gestational age (GA) and mode of delivery on the fecal VOC pattern in preterm infants born below 30 weeks of gestation. Longitudinal fecal samples, collected on days 7, 14, and 21 postnatally, were analyzed by an electronic nose device (Cyranose 320®). In total, 58 preterm infants were included (29 infants born at GA 24–26 weeks vs. 29 at 27–29 completed weeks, 24 vaginally born vs. 34 via C-section). No differences were identified at any predefined time point in terms of GA and delivery mode (p > 0.05). We, therefore, concluded that correction for these factors in this population is not warranted when performing fecal VOC analysis in the first three weeks of life.

Increased Risk

AbstractStudies in preterm infants have shown an association between late-onset sepsis (LOS) and the development of bronchopulmonary dysplasia (BPD). It is unknown whether clinical or biochemical characteristics during sepsis modulate the risk for BPD. This single-center retrospective cohort study included all patients with a gestational age < 30 weeks, born between 2009 and 2015, in whom empiric antimicrobial treatment was initiated > 72 h after birth and continued for at least 5 days, independent on microbiological results. The association between clinical and biochemical characteristics of LOS and the development of BPD in survivors were assessed with multivariate logistic regression analysis adjusted for early-onset sepsis, small for gestational age, and gestational age. Of the 756 admitted infants, 256 infants (mean GA: 27.0 weeks; birthweight: 924 grams) had at least one LOS episode, of whom 79 (30.9%) developed BPD. Analyses showed that only the need for and duration of mechanical ventilation during LOS were independently associated with an increased risk for BPD (adjusted OR 2.62, 95% CI 1.38, 4.96, p value 0.003, and OR 1.004, 95% CI 1.00, 1.007, p value 0.045, respectively).Conclusion: During a LOS, the need for and duration of mechanical ventilation are independently associated with the risk of developing BPD in preterm infants. What is Known:• Premature infants diagnosed with a late-onset sepsis are at higher risk of developing bronchopulmonary dysplasia• This association is mainly shown in infants with a positive blood culture What is New:• This study investigates the clinical and biochemical characteristics of late-onset sepsis and the development of bronchopulmonary dysplasia• The need for mechanical ventilation and duration of mechanical ventilation during late-onset sepsis are associated with an increased risk of developing bronchopulmonary dysplasia.

The Impact

Abstract Objective Small for gestational age (SGA) preterm infants (PT) are at greatest risk for growth failure. Our objective was to assess the impact of an exclusive human milk diet (HUM) on growth velocities and neonatal morbidities from birth to discharge in a SGA population. Study design Multicenter, retrospective cohort study, subgroup analysis of SGA PT comparing a cow’s milk diet (CMD) with HUM diet. Results At birth 420 PT were classified as SGA (197 CMD group, 223 HUM group). Demographics and anthropometric measurements were similar. HUM group PT showed improvement in length Z score at discharge (p = 0.024) and reduction in necrotizing enterocolitis (NEC) (p = 0.004). Conclusion SGA PT fed a HUM diet had significantly decreased incidence of NEC, surgical NEC, and late-onset sepsis. Due to concerns about growth in a HUM diet, it is reassuring SGA infants fed the HUM diet had similar growth to CMD diet with trends toward improvement.

Abstract Background Despite 15–17 millions of annual births in China, there is a paucity of information on prevalence and outcome of preterm birth. We characterized the outcome of preterm births and hospitalized preterm infants by gestational age (GA) in Huai’an in 2015, an emerging prefectural region of China. Methods Of 59,245 regional total births, clinical data on 2651 preterm births and 1941 hospitalized preterm neonates were extracted from Huai’an Women and Children’s Hospital (HWCH) and non-HWCH hospitals in 2018–2020. Preterm prevalence, morbidity and mortality rates were characterized and compared by hospital categories and GA spectra. Death risks of preterm births and hospitalized preterm infants in the whole region were analyzed with multivariable Poisson regression. Results The prevalence of extreme, very, moderate, late and total preterm of the regional total births were 0.14, 0.53, 0.72, 3.08 and 4.47%, with GA-specific neonatal mortality rates being 44.4, 15.8, 3.7, 1.5 and 4.3%, respectively. There were 1025 (52.8% of whole region) preterm admissions in HWCH, with significantly lower in-hospital death rate of inborn (33 of 802, 4.1%) than out-born (23 of 223, 10.3%) infants. Compared to non-HWCH, three-fold more neonates in HWCH were under critical care with higher death rate, including most extremely preterm infants. Significantly all-death risks were found for the total preterm births in birth weight < 1000 g, GA < 32 weeks, amniotic fluid contamination, Apgar-5 min < 7, and birth defects. For the hospitalized preterm infants, significantly in-hospital death risks were found in out-born of HWCH, GA < 32 weeks, birth weight < 1000 g, Apgar-5 min < 7, birth defects, respiratory distress syndrome, necrotizing enterocolitis and ventilation, whereas born in HWCH, antenatal glucocorticoids, cesarean delivery and surfactant use decreased the death risks. Conclusions The integrated data revealed the prevalence, GA-specific morbidity and mortality rate of total preterm births and their hospitalization, demonstrating the efficiency of leading referral center and whole regional perinatal-neonatal network in China. The concept and protocol should be validated in further studies for prevention of preterm birth.

Previous studies suggested that supplemental bovine lactoferrin (BLF) given to preterm infants (<32 weeks gestation) may reduce late onset sepsis (LOS) and necrotising enterocolitis (NEC), but have been underpowered. The Enteral Lactoferrin in Neonates (ELFIN) study, performed in the United Kingdom (UK), aimed to further address this issue with a well powered double blinded placebo controlled trial of >2200 preterm infants. ELFIN did not demonstrate a reduction in LOS or NEC, or several other clinically important measures. 316 (29%) of 1093 infants in the intervention group developed late-onset sepsis versus 334 (31%) of 1089 in the control group with an adjusted risk ratio of 0·95 (95% CI 0·86–1·04; p=0· 233). Reasons for the differences in ELFIN trial results and other studies may include population differences, the routine use of antifungals in the UK, timing of administration of the lactoferrin in relation to disease onset, or specific properties of the lactoferrin used in different trials. Further exploration is being undertaken in the UK NIHR funded Mechanisms Affecting the Guts of Preterm Infants in Enteral feeding trials (MAGPIE) study, for which results should be available soon.
