Background The high rates of culture-positive sepsis, sepsis-related mortality, and multidrug resistance in neonates admitted to special care newborn units in district hospitals (DH) in India necessitate urgent actions to prevent infections in these settings. Immediate kangaroo mother care (iKMC), initiated before stabilization within the first few hours of life, has been shown to reduce neonatal mortality among low birth weight (LBW) neonates admitted to tertiary care hospitals. However, the effect of iKMC on sepsis and sepsis-related mortality, particularly in DH, remains unclear. This study aims to evaluate whether iKMC can lower the incidence of mortality or culture-positive sepsis in LBW neonates admitted to neonatal units in district hospitals. Methods This stepped-wedge cluster randomized trial will be conducted in ten district hospitals in Chhattisgarh, India, over 42 months. All neonates weighing between 1000 and 1799 g at birth and admitted to the participating hospitals, in whom KMC can be initiated within 12 h of life, will be eligible for inclusion. During the pre-intervention period (control), routine KMC will be practiced at the sites as is. Following a baseline period of 6 months, iKMC will be implemented sequentially in ten steps across the ten study sites at intervals of 3 months. The intervention includes initiating continuous skin-to-skin contact with the mother or relatives within 12 h of life, continuing KMC until discharge or weight 2.5 kg, and providing breastfeeding support. The primary outcome is the incidence of all-cause neonatal mortality and/or culture-positive sepsis until 28 days of life. Relative risks with 95% confidence intervals will be reported and analyzed using a generalized linear mixed model. An intention-to-treat analysis will be conducted. Discussion The PRISM (Protective Role of Immediate KMC in neonatal Sepsis and Mortality) trial will sequentially implement iKMC for LBW neonates in ten district hospitals with a relatively high burden of sepsis in India. If proven effective in reducing the risks of sepsis or neonatal mortality, the trial will provide necessary evidence for its safety and efficacy, as well as the impetus for implementing and upscaling the intervention in district hospitals across India and other low- and middle-income countries.

ObjectiveDefinitive guidance regarding the duration of antibiotics for neonatal sepsis is lacking. We hypothesised that a 7-day antibiotic course is non-inferior to a 14-day course for treating culture-proven sepsis.DesignRandomised, controlled, non-inferiority trial with masked outcome assessment in eight centres in a low and middle-income country.PatientsNeonates with a birth weight (BW) ≥1000 g and blood culture-proven sepsis were randomised on day 7 of sensitive antibiotic therapy provided sepsis had clinically remitted. Exclusions: Staphylococcus aureus or fungal sepsis, and infections requiring prolonged antibiotics. We planned to enrol 350 per group, assuming 10% rate of primary outcome, +7% non-inferiority margin, one-sided 5% alpha, 90% power, 10% loss to follow-up.Intervention7 days (no further treatment); comparison: 14 days (7 days postrandomisation).OutcomesPrimary: relapse (definite or probable) within day 21 postantibiotic completion. Secondary outcomes: composite of mortality or definite/probable/secondary sepsis and duration of hospitalisation. One interim analysis (per protocol (PP)) was planned.Results126 and 135 subjects were recruited in 7-day and 14-day groups, respectively, with mean (SD) birth weight (BW) 2250.9 (741.1) and 2187.8 (718.8) g. The trial was terminated early, based on interim PP analysis. 2/125 and 6/130 subjects had the primary outcome in 7-day and 14-day groups, respectively (risk difference (RD)=−3.0% (99.5% CI −9.2%, +3.1%), below non-inferiority margin). The composite secondary outcome also favoured the 7-day regimen (RD: −3.7% (99.5% CI −12.4% to +5.1%)). Duration of hospitalisation was shorter in 7-day group (median difference: −4 days (95% CI −5 to –3)).ConclusionsA 7-day course of antibiotics may be non-inferior to a 14-day course for uncomplicated bacterial neonatal sepsis.Trial registration number NCT03280147.

Intrapartum azithromycin prophylaxis reduced maternal infections but showed no effect on neonatal sepsis and mortality. Although antibiotic exposure may indirectly alter the mycobiota (community of fungi that live in a given environment), there is no data available on how intrapartum azithromycin impacts gut mycobiota development. We hereby assess the impact of intrapartum azithromycin on gut mycobiota development from birth to the age of three years, by ITS2 gene profiling of rectal samples from 102 healthy Gambian infants selected from a double-blind randomized placebo-controlled clinical trial (PregnAnZI-2 – ClinicalTrials.org NCT03199547). In the trial, women received 2 g oral azithromycin or placebo (1:1) during labour with the intension of assessing effect on neonatal sepsis or mortality. Secondary objectives included effects on bacterial carriage and resistance, puerperal infections, and infant growth. Our analysis show that season and parity were key factors that influenced gut mycobiota development. Intrapartum azithromycin increased the abundance of Candida orthopsilosis but only in the wet season and did not show different effects by sex of the child. These data suggest that season and parity can be key factors influencing gut mycobiota development and may inform strategies for a wider implementation of intrapartum azithromycin intervention. Here, via ITS2 gene profiling of rectal samples from 102 healthy Gambian infants, the authors show that intrapartum azithromycin has an overall mild effect on gut mycobiota development but associates with increased abundance of C. orthopsilosis in the wet season.

Among infants born in Dhaka, Bangladesh, a 7-day regimen of Lactiplantibacillus plantarum ATCC 202195 (LP202195) plus fructooligosaccharide (FOS) did not colonize the infant gastrointestinal (GI) tract. The absence of colonization is inconsistent with a prior study of the same synbiotic regimen in India, in which LP202195 was shown to persist in the infant GI tract for up to 6 months. Sustained LP202195 colonization was thought to be required for the probiotic to impart its beneficial impact on newborn sepsis. Therefore, additional trials are warranted to confirm the previously observed effects of LP202195 on infant clinical outcomes in the absence of LP202195 colonization. Moreover, since regimens of LP202195 that did not include FOS were indistinguishable from the synbiotic in terms of colonization, safety, and tolerability, future trials should assess the role of FOS for clinical efficacy; removing FOS would reduce costs, an important consideration for scale-up. This study has been registered at ClinicalTrials.gov as NCT05180201 .

Background Vancomycin has been used in clinical practice for over 50 years; however, validated, pharmacokinetic (PK) data relating clinical outcomes to different dosing regimens in neonates are lacking. Coagulase negative staphylococci (CoNS) are the most commonly isolated organisms in neonatal, late-onset sepsis (LOS). Optimised use to maximise efficacy while minimising toxicity and resistance selection is imperative to ensure vancomycin’s continued efficacy. Methods NeoVanc is a European, open-label, Phase IIb, randomised, controlled, non-inferiority trial comparing an optimised vancomycin regimen to a standard vancomycin regimen when treating LOS known/suspected to be caused by Gram-positive organisms (excluding Staphylococcus aureus ) in infants aged ≤ 90 days. Three hundred infants will be recruited and randomised in a 1:1 ratio. Infants can be recruited if they have culture confirmed (a positive culture from a normally sterile site and at least one clinical/laboratory criterion) or clinical sepsis (presence of any ≥ 3 clinical/laboratory criteria) in the 24 h before randomisation. The optimised regimen consists of a vancomycin loading dose (25 mg/kg) followed by 5 ± 1 days of 15 mg/kg q12h or q8h, dependent on postmenstrual age (PMA). The standard regimen is a 10 ± 2 day vancomycin course at 15 mg/kg q24h, q12h or q8h, dependent on PMA. The primary endpoint is a successful outcome at the test of cure visit (10 ± 1 days after the end of vancomycin therapy). A successful outcome consists of the patient being alive, having successfully completed study vancomycin therapy and having not had a clinical/microbiological relapse/new infection requiring treatment with vancomycin or other anti-staphylococcal antibiotic for > 24 h. Secondary endpoints include clinical/microbiological relapse/new infection at the short-term follow-up visit (30 ± 5 days after the initiation of vancomycin), evaluation of safety (renal/hearing), vancomycin PK and assessment of a host biomarker panel over the course of vancomycin therapy. Discussion Based on previous pre-clinical data and a large meta-analysis of neonatal, PK/pharmacodynamic data, NeoVanc was set up to provide evidence on whether a loading dose followed by a short vancomycin course is non-inferior, regarding efficacy, when compared to a standard, longer course. If non-inferiority is demonstrated, this would support adoption of the optimised regimen as a way of safely reducing vancomycin exposure when treating neonatal, Gram-positive LOS.

Background Poor participant understanding of research information can be a problem in community interventional studies with rural African women, whose levels of illiteracy are high. This study aimed to improve the informed consent process for women living in rural eastern Uganda. We assessed the impact of alternative consent models on participants’ understanding of clinical trial information and their contribution to the informed consent process in rural Uganda. Methods The study applied a parallel mixed-methods design for a prospective comparative cohort, nested within a pilot study on the community distribution of an alcohol-based hand rub to prevent neonatal sepsis (BabyGel pilot trial). Women of at least 34 weeks’ pregnancy, suitable for inclusion in the BabyGel pilot trial, were recruited into this study from their homes in 13 villages in Mbale District. As part of the informed consent process, information about the trial was presented using one of three consent methods: standard researcher-read information, a slide show using illustrated text on a flip chart or a video showing the patient information being read as if by a newsreader in either English or the local language. In addition, all women received the patient information sheet in their preferred language. Each information-giving method was used in recruitment for 1 week. Two days after recruitment, women’s understanding of the clinical trial was evaluated using the modified Quality of Informed Consent (QuIC) tool. They were also shown the other two methods and their preference assessed using a 5-point Likert scale. Semi-structured interviews were administered to each participant. The interviews were audio-recorded, transcribed and translated verbatim, and thematically analysed. Results A total of 30 pregnant women in their homes participated in this study. Their recall of the trial information within the planned 48 h was assessed for the majority (90%, 27/30). For all three consent models, women demonstrated a high understanding of the study. There was no statistically significant difference between the slide-show message (mean 4.7; standard deviation, SD 0.47; range 4–5), video message (mean 4.9; SD 0.33; range 4–5) and standard method (mean 4.5; SD 0.53; range 4–5; all one-way ANOVA, p  = 0.190). The slide-show message resulted in the most objective understanding of question items with the highest average QuIC score of 100 points. For women who had been recruited using any of the three models, the slide show was the most popular method, with a mean score for all items of not less than 4.2 (mean 4.8; SD 0.6; range 4–5). Most women (63%, 19/30) preferred the slide-show message, compared with 17% (5/30) and 20% (6/30) for the standard and video messages, respectively. The reasons given included the benefits of having pictures to aid understanding and the logical progression of the information. Conclusion Our results from this small study suggest that slide-show messages may be an effective and popular alternative way of presenting trial information to women in rural Uganda, many of whom have little or no literacy.

Background Infections are the single most important cause of neonatal mortality in developing countries. Results from trials in Asia evaluating the effect of chlorhexidine on neonatal mortality have been encouraging but limited data are available on the impact of cord cleansing on bacterial colonization. Further, no data from facility deliveries and impact with time is available. This pilot study was aimed to evaluate the impact of 4 % commercially prepared chlorhexidine on cord colonization and density of colonization among newborns in India. Methods Three hundred twenty-six newborns (hospital-247; community-79) were enrolled within 24 h of birth and randomly assigned to one of three groups: chlorhexidine, placebo or dry cord care. Umbilical swabs were collected at baseline, 2- and 48- hours after intervention application. Results At baseline, growth positivity (any bacterial growth) was 20 % (50 of 247 swabs) and 81 % (64 of 79 swabs) among hospital and community born neonates, respectively. In both settings, chlorhexidine compared to placebo and dry cord care, reduced colonization following 2- and 48-hour post application. Chlorhexidine significantly reduced 48-hour post application colony counts in comparison to placebo [Hospital: mean difference = −1.01; 95 % CI: −1.72, −0.30 Community: mean difference = −1.76; 95 % CI: −2.60, −0.93] and dry cord care [Hospital: mean difference = −1.16; 95 % CI: −1.93, −0.39 Community: mean difference = −2.23; 95 % CI: −3.18, −1.29]. Differences were similar for gram-positive and gram-negative bacteria. Conclusions Cord cleansing with 4 % chlorhexidine soon after birth reduced colonization as well as density of colonization significantly; however this pilot study does not address the impact of chlorhexidine on mortality. The control preparation neither increased or decreased colonization. Trial registration Clinical Trial Registration: clinicaltrials.gov: NCT01528852, Registered February 7, 2012.

In Switzerland and other high-income countries, one out of 3000 to 5000 term and late preterm neonates develops early onset sepsis (EOS) associated with a mortality of around 3%, while incidence and mortality of EOS in very preterm infants are substantially higher. Exposure to antibiotics for suspected EOS is disproportionally high compared to the incidence of EOS with consequences for future health and antimicrobial resistance (AMR). A safe reduction of unnecessary antibiotic treatment has to be a major goal of new management strategies and guidelines. Antibiotics should be administered immediately in situations with clinical signs of septic shock. Group B streptococcus (GBS) and Escherichia coli ( E. coli ) are the leading pathogens of EOS. Amoxicillin combined with an aminoglycoside remains the first choice for empirical treatment. Serial physical examinations are recommended for all neonates with risk factors for EOS. Neonates without any clinical signs suggestive of EOS should not be treated with antibiotics. In Switzerland, we do not recommend the use of the EOS calculator, a risk stratification tool, due to its unclear impact in a population with an observed antibiotic exposure below 3%. Not all neonates with respiratory distress should be empirically treated with antibiotics. Isolated tachypnea or respiratory distress starting immediately after delivery by elective caesarean section or a clearly assessed alternative explanation than EOS for clinical signs may point towards a low probability of sepsis. On the other hand, unexplained prematurity with risk factors has an inherent higher risk of EOS. Before the start of antibiotic therapy, blood cultures should be drawn with a minimum volume of 1 ml in a single aerobic blood culture bottle. This standard procedure allows antibiotics to be stopped after 24 to 36 h if no pathogen is detected in blood cultures. Current data do not support the use of PCR-based pathogen detection in blood as a standard method. Lumbar puncture is recommended in blood culture–proven EOS, critical illness, or in the presence of neurological symptoms such as seizures or altered consciousness. The accuracy of a single biomarker measurement to distinguish inflammation from infection is low in neonates. Therefore, biomarker guidance is not a standard part of decision-making regarding the start or stop of antibiotic therapy but may be used as part of an algorithm and after appropriate education of health care teams. Every newborn started on antibiotics should be assessed for organ dysfunction with prompt initiation of respiratory and hemodynamic support if needed. An elevated lactate may be a sign of poor perfusion and requires a comprehensive assessment of the clinical condition. Interventions to restore perfusion include fluid boli with crystalloids and catecholamines. Neonates in critical condition should be cared for in a specialized unit. In situations with a low probability of EOS, antibiotics should be stopped as early as possible within the first 24 h after the start of therapy. In cases with microbiologically proven EOS, reassessment and streamlining of antibiotic therapy in neonates is an important step to minimize AMR. Conclusion : This guideline, developed through a critical review of the literature, facilitates a probability-based approach to the management of neonates at risk of early onset sepsis. What is Known: • Neonatal exposure to antibiotics is disproportionally high compared with the incidence of early onset sepsis with implications for future health and antimicrobial resistance. What is New: • A probability-based approach may facilitate a more balanced management of neonatal sepsis and antibiotic stewardship.

Antimicrobial resistance in neonatal sepsis is rising, yet mechanisms of resistance that often spread between species via mobile genetic elements, ultimately limiting treatments in low- and middle-income countries (LMICs), are poorly characterized. The Burden of Antibiotic Resistance in Neonates from Developing Societies (BARNARDS) network was initiated to characterize the cause and burden of antimicrobial resistance in neonatal sepsis for seven LMICs in Africa and South Asia. A total of 36,285 neonates were enrolled in the BARNARDS study between November 2015 and December 2017, of whom 2,483 were diagnosed with culture-confirmed sepsis. Klebsiella pneumoniae ( n  = 258) was the main cause of neonatal sepsis, with Serratia marcescens ( n  = 151), Klebsiella michiganensis ( n  = 117), Escherichia coli ( n  = 75) and Enterobacter cloacae complex ( n  = 57) also detected. We present whole-genome sequencing, antimicrobial susceptibility and clinical data for 916 out of 1,038 neonatal sepsis isolates (97 isolates were not recovered from initial isolation at local sites). Enterobacterales ( K. pneumoniae, E. coli and E. cloacae ) harboured multiple cephalosporin and carbapenem resistance genes. All isolated pathogens were resistant to multiple antibiotic classes, including those used to treat neonatal sepsis. Intraspecies diversity of K. pneumoniae and E. coli indicated that multiple antibiotic-resistant lineages cause neonatal sepsis. Our results will underpin research towards better treatments for neonatal sepsis in LMICs. Genomic and clinical analysis of 916 bacterial isolates from neonates with sepsis in seven low- and middle-income countries (the BARNARDS study) reveals that the main species present were antimicrobial-resistant Klebsiella , Escherichia coli and Enterobacter .

ObjectiveDetermine risk of death or neurodevelopmental impairment (NDI) in infants with late-onset sepsis (LOS) versus late-onset, antibiotic-treated, blood culture-negative conditions (LOCNC).DesignRetrospective cohort study.Setting24 neonatal centres.PatientsInfants born 1/1/2006–31/12/2014, at 22–26 weeks gestation, with birth weight 401–1000 g and surviving >7 days were included. Infants with early-onset sepsis, necrotising enterocolitis, intestinal perforation or both LOS and LOCNC were excluded.ExposuresLOS and LOCNC were defined as antibiotic administration for ≥5 days with and without a positive blood/cerebrospinal fluid culture, respectively. Infants with these diagnoses were also compared with infants with neither condition.OutcomesDeath or NDI was assessed at 18–26 months corrected age follow-up. Modified Poisson regression models were used to estimate relative risks adjusting for covariates occurring ≤7 days of age.ResultsOf 7354 eligible infants, 3940 met inclusion criteria: 786 (20%) with LOS, 1601 (41%) with LOCNC and 1553 (39%) with neither. Infants with LOS had higher adjusted relative risk (95% CI) for death/NDI (1.14 (1.05 to 1.25)) and death before follow-up (1.71 (1.44 to 2.03)) than those with LOCNC. Among survivors, risk for NDI did not differ between the two groups (0.99 (0.86 to 1.13)) but was higher for LOCNC infants (1.17 (1.04 to 1.31)) compared with unaffected infants.ConclusionsInfants with LOS had higher risk of death, but not NDI, compared with infants with LOCNC. Surviving infants with LOCNC had higher risk of NDI compared with unaffected infants. Improving outcomes for infants with LOCNC requires study of the underlying conditions and the potential impact of antibiotic exposure.
