Early neonatal outcomes in infants of mothers with organ transplantation under immunosuppressive treatment.

BACKGROUND: This study aimed to examine early clinical and laboratory findings in infants born to mothers who had organ transplants and received immunosuppressive treatment. METHODS: Between 2016 and 2023, the study examined infants of mothers who underwent organ transplantation and were receiving immunosuppressive treatment, and followed at the Department of Neonatology at Akdeniz University. Demographic, clinical, and laboratory characteristics of mothers and infants were recorded. On the first day of life, complete blood count values were examined, as well as potassium levels on the first, third, and seventh days, and creatinine levels on the third and seventh days. The tacrolimus blood level was calculated by taking the average of the tacrolimus blood values of the mother measured during the pregnancy. The infants were evaluated for any potential morbidities caused by intrauterine immunosuppressive drug exposure. RESULTS: The study included 21 mothers (some with multiple pregnancies) and 27 infants. According to the findings of this study, 74% of these infants were born premature, 67% had low birth weight, and all were delivered via cesarean section. Prematurity was associated with the morbidities found in the infants. In the early period, lymphopenia was detected in 37%, neutropenia in 25.9%, thrombocytopenia in 11.1%, hyperkalemia in 18.5%, and creatinine elevation in 7.4%, all of which returned to normal within a few days. There was no significant relationship between maternal tacrolimus blood levels and infant potassium and creatinine levels. CONCLUSION: Apart from an increased risk of prematurity, low birth weight, and cesarean delivery, no effects were observed in these infants during the early period. However, long-term follow-up is necessary to monitor for any potential morbidities.

Oral glucose gel in the prevention of neonatal hypoglycemia: A systematic review and meta-analysis.

BACKGROUND: Neonatal hypoglycemia (NH) is the most prevalent metabolic disorder in neonates and glucose gel in oral solution is a relatively new treatment option for NH. We aimed to determine whether oral glucose gel can prevent NH. METHODS: We conducted an open literature search using PubMed, Embase, Cochrane Library, and Web of Science. We used relative risk as the statistical data, expressed each outcome effect as a 95% confidence interval, and conducted a heterogeneity test. If heterogeneity statistics indicated that I2 was ≥ 50%, the random effects model analysis was used; otherwise, the fixed effects model analysis was conducted, and sensitivity analyses were conducted for all outcomes. RESULTS: In this review, we included a total of 10 studies involving 4801 neonates. Meta-analysis revealed that there were no significant differences between the preventive oral glucose gel group and the control group in terms of blood glucose concentration, glucose concentration 30 minutes after the first breastfeeding, length of stay, Bayley-III composite score, subsequent need for intravenous injection of glucose, 24-hour glucose > 50 mg/dL, separation from mother for treatment of hypoglycemia/admitted to neonatal intensive care unit for hypoglycemia, normoglycemia after 1 to 2 treatments, or normoglycemia after more than 2 treatments, breastfeeding at discharge, delayed feeding, neurosensory impairment, parental satisfaction, developmental delay, and seizure. The subsequent intake was significantly lower in the glucose gel group compared to the control group. INTERPRETATION: The use of oral glucose gel as a preventative measure may not reduce the incidence of NH. In order to assess the efficacy of glucose gel in preventing NH, a more high-quality, large-sample, and rigorously designed randomized controlled trial is required.

[Neonatal hypoglycemia: glucose gel efficacy in the treatment of early hypoglycemia in newborns with risk factors. Randomized clinical trial]. / Hipoglucemia neonatal: eficacia de la glucosa gel en el tratamiento de la hipoglucemia precoz en recién nacidos con factores de riesgo. Ensayo clínico aleatorizado.

Hypoglycemia is the most frequent metabolic disorder in newborns; the administration of 40% glu cose gel in the oral mucosa could be as effective in its correction as the administration of formula milk, not interfering with breastfeeding. OBJECTIVE: To evaluate the efficacy of 40% glucose gel com pared with formula milk in the treatment of early asymptomatic hypoglycemia in newborns with risk factors. PATIENTS AND METHOD: Randomized clinical trial, non-inferiority, conducted in a private hos pital. Newborns attended in rooming-in with the following risk factors were included: late preterm, large and small for gestational age at term, and children of diabetic mothers. In the presence of hy poglycemia, one group received 40% glucose gel (A) in the oral mucosa and another group received formula milk (B). Therapeutic failure was considered as persistence or repetition of hypoglycemia in the first 48h of life. RESULTS: 866 NBs with risk factors were registered over 36 month; 278 (32.1 %) presented hypoglycemia; 105 NBs in group A and 115 in group B completed the study. 75 (71 %) NBs in group A and 104 (90,4 %) in group B achieved hypoglycemia correction. After analyzing the trends obtained, it was decided to discontinue the study. CONCLUSIONS: The administration of 40% glucose gel was not equivalent to the administration of formula milk in the treatment of early asymptomatic hypoglycemia in newborns with risk factors.

Successful Eradication of a Highly Resistant Elizabethkingia anophelis Species in a Premature Neonate With Bacteremia and Meningitis.

Elizabethkingia anophelis is a Gram-negative bacillus that can exhibit highly resistant phenotypes against most antibiotics with evidence of efficacy and safety in the neonatal population. Given the limited antimicrobial options, clinicians may be forced into challenging treatment scenarios when faced with central nervous system infections in premature neonates caused by E. anophelis . We report a case of successful treatment of hospital-acquired meningitis and bacteremia caused by E. anophelis at 11 days of life in a male infant born at 29 weeks, 1 day gestation and birth weight of 1.41 kg. Therapy consisted of vancomycin, dose adjusted to maintain goal troughs of 15-20 mg/L, and rifampin 10 mg/kg/dose every 12 hours, with ciprofloxacin 15 mg/kg/dose every 12 hours and trimethoprim/sulfamethoxazole 5 mg/kg/dose every 12 hours added due to antimicrobial susceptibilities and unsatisfactory response, for a total of 21 days. Following initiation of this multidrug regimen, repeat cultures were negative, laboratory parameters improved [with exception of elevated cerebrospinal fluid (CSF) white blood cell count], the patient remained otherwise stable, and there were no adverse effects noted from therapy. Complications after treatment included the requirement of bilateral hearing aids and the development of hydrocephalus necessitating ventriculoperitoneal shunt placement. To our knowledge, we report the first case of meningitis in a premature neonate initially identified as E. anophelis in the United States treated with this regimen which led to successful microbiologic eradication with no antimicrobial safety concerns.

Antenatal Neuroprotective Magnesium Sulfate in Very Preterm Infants and Its Association With Feeding Intolerance.

INTRODUCTION/OBJECTIVE: Magnesium sulfate (MgSO 4 ) treatment is widely used for fetal neuroprotection despite the controversy concerning the side effects. There is limited data regarding the impact of various cumulative maternal doses and neonatal serum magnesium (Mg) levels on short-term neonatal morbidity and mortality. We opted to carry out a study to determine the impact of neonatal serum Mg levels on neonatal outcomes. METHOD: We conducted this prospective observational study between 2017 and 2021. Antenatal MgSO 4 was used for neuroprotective purpose only during the study period. Inborn preterm infants delivered between 23 and 31 6/7 weeks of gestation were enrolled consecutively. Babies who underwent advanced resuscitation in the delivery room, inotropic treatment due to hemodynamic instability in the first 7 days of life, >12 hours since the discontinuation of maternal MgSO 4 treatment, severe anemia, and major congenital/chromosomal anomalies were excluded from the study. The subgroup of babies with serum Mg level at the 6th hour of life underwent an analysis. A neonatal Mg concentration of 2.5 mg/dL was used to classify MgSO 4 -exposed patients into 2 groups (<2.5 mg/dL and ≥2.5 mg/dL). Another analysis was performed between babies whose mothers were exposed to MgSO 4 and those not exposed. Finally, the groups' neonatal outcomes were compared. RESULTS: Of the 584 babies, 310 received antenatal MgSO 4 . The birth weights were significantly lower in the MgSO 4 exposed group (1113 ± 361 g vs 1202 ± 388 g, P = 0.005). Antenatal corticosteroid usage and intrauterine growth restriction were also noted to be higher. The MgSO 4 group was more likely to have bronchopulmonary dysplasia, prolonged invasive ventilation, necrotizing enterocolitis, delayed enteral nutrition, and feeding intolerance ( P < 0.05). MgSO 4 treatment was shown as an independent risk factor for feeding intolerance when corrected for confounders (odds ratio 2.13, 95% confidence interval: 1.4-3.1, P = 0.001). Furthermore, serum Mg level significantly correlated with feeding intolerance ( r = 0.21, P = 0.002). CONCLUSION: This study highlighted the effect of MgSO 4 treatment and the potential superiority of serum Mg level as a predictor of immediate neonatal outcomes, particularly delayed enteral nutrition and feeding intolerance. Further studies are warranted to ascertain the optimal serum Mg concentration of preterm infants in early life to provide maximum benefit with minimal side effects.

The role of intestinal alkaline phosphatase in the development of necrotizing enterocolitis.

Necrotizing enterocolitis (NEC) is a devastating neonatal disease that affects neonates worldwide and often leads to high morbidity and mortality rates. Despite extensive research, the cause of NEC remains unclear, and current treatment options are limited. An important novel finding is the potential role of intestinal Alkaline Phosphatase (IAP) in both pathogenesis and treatment of NEC. IAP can play a vital role in detoxifying liposaccharides (LPS), a key mediator of many pathological processes, thereby reducing the inflammatory response associated with NEC. Furthermore, IAP can help prevent dysbiosis, improve intestinal perfusion, and promote autophagy. In this comprehensive review, we present evidence of the possible connection between IAP and the LPS/Toll-like receptor 4 (TLR4) pathway, impaired gut immunity, and dysbiosis in the preterm gut. Based on these findings, the administration of exogenous IAP might provide promising preventive and therapeutic avenues for the management of NEC.

Growth response of syndromic versus non-syndromic children born small for gestational age (SGA) to growth hormone therapy: a Belgian study.

Introduction: A substantial proportion of SGA patients present with a syndrome underlying their growth restriction. Most SGA cohorts comprise both syndromic and non-syndromic patients impeding delineation of the recombinant human growth hormone (rhGH) response. We present a detailed characterization of a SGA cohort and analyze rhGH response based on adult height (AH). Methods: Clinical and auxological data of SGA patients treated with rhGH, who had reached AH, were retrieved from BELGROW, a national database of all rhGH treated patients held by BESPEED (BElgian Society for PEdiatric Endocrinology and Diabetology). SGA patients were categorized in syndromic or non-syndromic patients. Results: 272 patients were included, 42 classified as syndromic (most frequent diagnosis (n=6): fetal alcohol syndrome and Silver-Russell syndrome). Compared with non-syndromic patients, syndromic were younger [years (median (P10/P90)] 7.43 (4.3/12.37) vs 10.21 (5.43/14.03), p=0.0005), shorter (height SDS -3.39 (-5.6/-2.62) vs -3.07 (-3.74/-2.62), p=0.0253) and thinner (BMI -1.70 (-3.67/0.04) vs -1.14 (-2.47/0.27) SDS, p=0.0054) at start of rhGH treatment. First year rhGH response was comparable (delta height SDS +0.54 (0.24/0.94) vs +0.56 (0.26/0.92), p=0.94). Growth pattern differed with syndromic patients having a higher prepubertal (SDS +1.26 vs +0.83, p=0.0048), but a lower pubertal height gain compared to the non-syndromic group (SDS -0.28 vs 0.44, p=0.0001). Mean rhGH dose was higher in syndromic SGA patients (mg/kg body weight/day 0.047 (0.039/0.064) vs 0.043 (0.035/0.056), p=0.0042). AH SDS was lower in syndromic SGA patients (-2.59 (-4.99/-1.57) vs -2.32 (-3.3/-1.2), p=0.0107). The majority in both groups remained short (<-2 SDS: syndromic 71%, non-syndromic 63%). Total height gain was comparable in both groups (delta height SDS +0.76 (-0.70/1.48) vs +0.86 (-0.12/1.86), p=0.41). Conclusions: Compared to non-syndromic SGA patients, syndromic SGA patients were shorter when starting rhGH therapy, started rhGH therapy earlier, and received a higher dose of rhGH. At AH, syndromic SGA patients were shorter than non-syndromic ones, but their height gain under rhGH therapy was comparable.

[Prenatal rescue dose of betamethasone in the preterm infant with intrauterine growth restriction]. / Dosis prenatal de rescate de betametasona en el prematuro con restricción del crecimiento intrauterino.

Antenatal corticosteroids reduce mortality and respiratory distress syndrome (RDS) in preterm newborns. These benefits decrease after a week of administration, recommending a rescue therapy if there is a new threat of premature delivery. Repeated administration of antenatal corticosteroids may have deleterious effects and their benefits are controversial in intrauterine growth restriction (IUGR). OBJECTIVE: to verify the effects in the IUGR population of antenatal betamethasone rescue therapy on neonatal morbidity and mortality, RDS, and neurodevelopment at 2 years. PATIENTS AND METHOD: Retrospective study including ≤ 34 weeks and ≤ 1,500g preterm newborns divided according to antenatal betamethasone exposure: Single-cycle (2 doses) vs Rescue therapy (3 doses). Subgroups were created for those ≥ 30 weeks. Both cohorts were followed up to 24 months of corrected age. The Ages & Stages Questionnaires (ASQ)® was administered to assess neurodevelopment. RESULTS: 62 preterm infants with a diagnosis of IUGR were included. The rescue therapy group compared with the single-dose group showed no differences in morbidity and mortality and less intubation rate at birth (p = 0.02), with no differences in respiratory support at 7 days of life. Preterm newborns ≥ 30 weeks exposed to rescue therapy showed higher morbidity and mortality (p = 0.03) and bronchopulmonary dysplasia (BPD) (p = 0.02), showing no differences in RDS. The rescue therapy group showed worse mean scores on the ASQ-3 scale, with no significant differences in cerebral palsy or sensory deficits. CONCLUSIONS: Rescue therapy reduces intubation at birth but does not reduce morbidity and mortality. However, at > 30 weeks, this benefit is not observed and the IUGR population exposed to rescue therapy presented more BPD and lower scores on the ASQ-3 scale at 2 years. Future studies should be aimed at the individualization of antenatal corticosteroid therapy.

Next-generation sequencing-based detection of Ureaplasma in the gastric fluid of neonates with respiratory distress and chorioamnionitis.

BACKGROUND: Respiratory distress is common in neonates admitted to neonatal intensive care units. Additionally, infectious diseases such as intrauterine infections or vertical transmission are important underlying causes of respiratory failure. However, pathogens often cannot be identified in neonates, and there are many cases in which antibacterial drugs are empirically administered. Next-generation sequencing (NGS) is advantageous in that it can detect trace amounts of bacteria that cannot be detected by culturing or bacteria that are difficult to cultivate. However, there are few reports on the diagnosis of infectious diseases using NGS in the neonatal field, especially those targeting respiratory distress. OBJECTIVE: The purpose of our study was to investigate the microorganisms associated with neonatal respiratory distress and to determine whether less invasive collection specimens such as plasma and gastric fluid are useful. METHODS: Neonates were prospectively recruited between January and August 2020 from Nagoya University Hospital. The inclusion criteria were as follows: 1) admission to the neonatal intensive care unit; 2) respiratory distress presentation within 48 h of birth; and 3) suspected infection, collection of blood culture, and administration of antibiotics. Plasma samples and blood cultures were simultaneously collected. Gastric fluid samples were also collected if the patient was not started on enteral nutrition. Information on the patients and their mothers were collected from the medical records. DNA was extracted from 140 µL of plasma and gastric fluid samples. DNA sequencing libraries were prepared, and their quality was analyzed. DNA libraries were sequenced using high-throughput NGS. The NGS data of plasma and gastric fluid samples were analyzed using the metagenomic pipeline PATHDET, which calculated the number of reads assigned to microorganisms and their relative abundance. Putative pathogens were listed. RESULTS: Overall, 30 plasma samples and 25 gastric fluid samples from 30 neonates were analyzed. Microorganism-derived reads of gastric fluid samples were significantly higher than those of plasma samples. Transient tachypnea of the newborn was the most common cause of respiratory distress with 13 cases (43%), followed by respiratory distress syndrome with 7 cases (23%). There were 8 cases (29%) of chorioamnionitis and 7 cases (25%) of funisitis pathologically diagnosed. All blood cultures were negative, and only two gastric fluid cultures were positive for group B Streptococcus (Patient 15) and Candida albicans (Patient 24). Putative pathogens that met the positive criteria for PATHET were detected in four gastric fluid samples, one of which was group B Streptococcus from Patient 15. In the gastric fluid sample of Patient 24, Candida albicans were detected by NGS but did not meet the positive criteria for PATHDET. Cluster analysis of the plasma samples divided them into two study groups, and the indicator genera of each cluster (Phormidium or Toxoplasma) are shown in Figure 1. Clinical findings did not show any significant differences between the two groups. Cluster analysis of the gastric fluid samples divided them into three study groups, and the indicator genera of each cluster (Ureaplasma, Nostoc, and Streptococcus) are shown in Figure 2. The incidence rate of chorioamnionitis was significantly higher in Ureaplasma group than in the other two groups. CONCLUSION: Gastric fluid may be useful for assessing neonatal patients with respiratory distress. To the best of our knowledge, this was the first study to reveal that the presence of Ureaplasma in the gastric fluid of neonates with respiratory distress was associated with chorioamnionitis. The early diagnosis of intra-amniotic infections using gastric fluid and its treatment may change the treatment strategy for neonatal respiratory distress. Screening for Ureaplasma in neonates with respiratory distress may reduce the need for empirical antibiotic administration. Further research is required to confirm these findings.

Life-threatening complication: the development of necrotising fasciitis in a preterm neonate with omphalitis.

Omphalitis is a mild medical condition that can turn severe in exceptional situations leading to necrotising fasciitis. The most common cause of omphalitis is umbilical vein catheterisation (UVC) where the cleanliness measures can be compromised. The treatment options for omphalitis include antibiotics, debridement and supportive care. Sadly, the fatality rate in such cases is high. This report is about a premature female baby who was admitted to a neonatal intensive care unit after her birth at 34 weeks of gestation. UVC was performed on her which led to abnormal changes in the skin around her umbilicus. Further tests revealed that she had omphalitis and was treated with antibiotics and supportive care. Unfortunately, her condition quickly worsened and she was diagnosed with necrotising fasciitis which ultimately resulted in her death. This report provides details about the patient's symptoms, course of illness and treatment for necrotising fasciitis.

Case report: Better late than never, but sooner is better: switch from CSII to sulfonylureas in two patients with neonatal diabetes due to KCNJ11 variants.

Neonatal diabetes mellitus (NDM) is a rare genetic disease characterized by severe hyperglycemia requiring insulin therapy with onset mostly within the first 6 months and rarely between 6-12 months of age. The disease can be classified into transient (TNDM) or permanent neonatal diabetes mellitus (PNDM), or it can be a component of a syndrome. The most frequent genetic causes are abnormalities of the 6q24 chromosomal region and mutations of the ABCC8 or KCNJ11 genes coding for the pancreatic beta cell's potassium channel (KATP). After the acute phase, patients with ABCC8 or KCNJ11 mutations treated with insulin therapy can switch to hypoglycemic sulfonylureas (SU). These drugs close the KATP channel binding the SUR1 subunit of the potassium channel and restoring insulin secretion after a meal. The timing of this switch can be different and could affect long-term complications. We describe the different management and clinical outcome over the time of two male patients with NDM due to KCNJ11 pathogenetic variants. In both cases, continuous subcutaneous insulin infusion pumps (CSII) were used to switch therapy from insulin to SU, but at different times after the onset. The two patients kept adequate metabolic control after the introduction of glibenclamide; during the treatment, insulin secretion was evaluated with c-peptide, fructosamine, and glycated hemoglobin (HbA1c), which were within the normal range. In neonates or infants with diabetes mellitus, genetic testing is an indispensable diagnostic tool and KCNJ11 variants should be considered. A trial of oral glibenclamide must be considered, switching from insulin, the first line of NDM treatment. This therapy can improve neurological and neuropsychological outcomes, in particular in the case of earlier treatment initiation. A new modified protocol with glibenclamide administered several times daily according to continuous glucose monitoring profile indications, was used. Patients treated with glibenclamide maintain good metabolic control and prevent hypoglycemia, neurological damage, and apoptosis of beta cells during long-term administration.

Disseminating MSSA Infection in a Preterm Infant With Rare Finding of Spinal Epidural Abscess: A Case Report.

BACKGROUND: Methicillin-susceptible Staphylococcus aureus (MSSA) occurs more frequently in the neonatal intensive care unit (NICU) than methicillin-resistant S. aureus (MRSA) and can result in comparable morbidity and mortality in the neonatal population. MSSA infection may present as pustulosis or cellulitis and evolve into bacteremia, pneumonia, endocarditis, brain abscesses, and osteomyelitis. There is a paucity of literature regarding the treatment and long-term outcomes in the premature infant. CLINICAL FINDINGS: A 32-week twin developed MSSA sepsis with presentation of pain, decreased movement of upper extremities, and global hypotonia. Blood cultures remained positive despite antibiotic coverage. PRIMARY DIAGNOSIS: The infant was admitted to the level IV NICU with the diagnosis of MSSA bacteremia, with concern for dissemination and osteomyelitis. INTERVENTIONS: Diagnostic studies included laboratory testing for sepsis evaluation, radiologic studies to evaluate for dissemination, immunologic testing to rule out complement deficiency, and hematology testing to rule out hypercoagulable conditions. OUTCOMES: Diagnostic testing showed extensive cellulitis, osteomyelitis, multiple liver abscesses, and epidural abscesses suggestive of spinal epidural abscess (SEA). Abscess debridement and irrigation on the left distal femur, left elbow, and right tibia were performed. The infant completed 8 weeks of IV antibiotic therapy. Immunologic and hematology testing was within normal limits. PRACTICE RECOMMENDATIONS: Prompt recognition and follow-up for clinical signs of sepsis are vital when caring for premature infants. Inclusion of pediatric subspecialist recommendations to assure all diagnostic studies and treatments are completed can significantly impact the patient's outcome. Long-term follow-up is needed for premature infants with the diagnosis of SEA.

The Role of the Interleukin-1 Family in Complications of Prematurity.

Preterm birth is a major contributor to neonatal morbidity and mortality. Complications of prematurity such as bronchopulmonary dysplasia (BPD, affecting the lung), pulmonary hypertension associated with BPD (BPD-PH, heart), white matter injury (WMI, brain), retinopathy of prematurity (ROP, eyes), necrotizing enterocolitis (NEC, gut) and sepsis are among the major causes of long-term morbidity in infants born prematurely. Though the origins are multifactorial, inflammation and in particular the imbalance of pro- and anti-inflammatory mediators is now recognized as a key driver of the pathophysiology underlying these illnesses. Here, we review the involvement of the interleukin (IL)-1 family in perinatal inflammation and its clinical implications, with a focus on the potential of these cytokines as therapeutic targets for the development of safe and effective treatments for early life inflammatory diseases.

Neonatal herpes simplex presenting as a zosteriform eruption.

Herpes simplex virus (HSV) infection in newborn infants is a potentially devastating disease leading to death and disability. Skin, eye and mouth (SEM) infections account for approximately half of the cases in the USA. The appearance of skin findings often guides clinicians towards early diagnosis of HSV infection, prompt interventions and life-saving management; however, less than half of neonates with proven disease present with characteristic vesicular lesions. Furthermore, if SEM infections are not treated promptly, there is significant risk of progression to central nervous system and disseminated disease. We present a case of HSV-2 infection in a neonate with an atypical zosteriform eruption on day 3 of life. This case demonstrates that neonatal HSV can unusually present in a zosteriform rash. By elucidating this unique presentation, we highlight atypical HSV skin presentation and emphasise on the importance of earlier diagnosis and antiviral treatment to prevent the associated morbidity and mortality.

Empirical Antimicrobial Therapy of Neonates with Necrotizing Enterocolitis: A Systematic Review.

OBJECTIVE: Necrotizing enterocolitis (NEC) is an inflammatory disease of the gastrointestinal tract characterized by ischemic necrosis of the intestinal mucosa, mostly affecting premature neonates. Management of NEC includes medical care and surgical approaches, with supportive care and empirical antibiotic therapy recommended to avoid any disease progression. However, there is still no clear evidence-based consensus on empiric antibiotic strategies or surgical timing. This study was aimed to review the available evidence on the effectiveness and safety of different antibiotic regimens for NEC. STUDY DESIGN: MEDLINE, EMBASE, Cochrane CENTRAL, and CINAHL databases were systematically searched through May 31, 2020. Randomized controlled trials (RCTs) and nonrandomized interventions reporting data on predefined outcomes related to NEC treatments were included. Clinical trials were assessed using the criteria and standard methods of the Cochrane risk of bias tool for randomized trials, while the risk of bias in nonrandomized studies of interventions was evaluated using the ROBINS-I tool. The certainty in evidence of each outcome's effects was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. RESULTS: Five studies were included in this review, two RCTs and three observational studies, for a total amount of 3,161 patients. One RCT compared the outcomes of parenteral (ampicillin plus gentamicin) and oral (gentamicin) treatment with parenteral only. Three studies (one RCT and two observational) evaluated adding anaerobic coverage to different parenteral regimens. The last observational study compared two different parenteral antibiotic combinations (ampicillin and gentamicin vs. cefotaxime and vancomycin). CONCLUSION: No antimicrobial regimen has been shown to be superior to ampicillin and gentamicin in decreasing mortality and preventing clinical deterioration in NEC. The use of additional antibiotics providing anaerobic coverage, typically metronidazole, or use of other broad-spectrum regimens as first-line empiric therapy is not supported by the very limited current evidence. Well-conducted, appropriately sized comparative trials are needed to make evidence-based recommendations. KEY POINTS: · Ampicillin and gentamicin are effective in decreasing mortality and preventing clinical deterioration in NEC.. · Metronidazole could be added in patients with surgical NEC.. · No study with high-quality evidence was found..

Outcome at 4.5 years after dextrose gel treatment of hypoglycaemia: follow-up of the Sugar Babies randomised trial.

OBJECTIVE: Dextrose gel is used to treat neonatal hypoglycaemia, but later effects are unknown. DESIGN AND SETTING: Follow-up of participants in a randomised trial recruited in a tertiary centre and assessed in a research clinic. PATIENTS: Children who were hypoglycaemic (<2.6 mmol/L) recruited to the Sugar Babies Study (>35 weeks, <48 hours old) and randomised to treatment with 40% dextrose or placebo gel. INTERVENTIONS: Assessment of neurological status, cognitive ability (Weschler Preschool and Primary Scale of Intelligence), executive function (five tasks), motor function (Movement Assessment Battery for Children-2 (MABC-2)), vision, visual processing (Beery-Buktenica Development Test of Visual Motor Integration (Beery VMI) and motion coherence thresholds) and growth at 2 years. MAIN OUTCOME MEASURES: Neurosensory impairment (cerebral palsy; visual impairment; deafness; intelligence quotient <85; Beery VMI <85; MABC-2 score <15th centile; low performance on executive function or motion coherence). RESULTS: Of 237 babies randomised, 185 (78%) were assessed; 96 randomised to dextrose and 89 to placebo gel. Neurosensory impairment was similar in both groups (dextrose 36/96 (38%) vs placebo 34/87 (39%), relative risk 0.96, 95% CI 0.66 to 1.34, p=0.83). Secondary outcomes were also similar, except children randomised to dextrose had worse visual processing scores (mean (SD) 94.5 (15.9) vs 99.8 (15.9), p=0.02) but no differences in the proportion with visual processing scores <85 or other visual test scores. Children randomised to dextrose gel were taller (z-scores 0.18 (0.97) vs -0.17 (1.01), p=0.001) and heavier (0.57 (1.07) vs 0.29 (0.92), p=0.01). CONCLUSIONS: Treatment of neonatal hypoglycaemia (<2.6 mol/L) with dextrose gel does not alter neurosensory impairment at 4.5 years. However, further assessment of visual processing and growth may be warranted. TRIAL REGISTRATION NUMBER: ACTRN1260800062392.
