Factors associated with neonatal sepsis among neonates admitted in Kibungo Referral Hospital, Rwanda

More than one million neonatal deaths occur every year worldwide, of which 99% take place in low-income countries. In Rwanda, nearly 71% of neonatal deaths are preventable and among these, 10% are due to neonatal sepsis. Nevertheless, limited information exists on neonatal sepsis and its associated factors in Rwanda. The objectives of the study were to find prevalence and factors associated with neonatal sepsis among neonates admitted in Kibungo Referral Hospital, Ngoma District, Rwanda. We used a retrospective cross-sectional study design reviewing a subset of neonatal, maternal and laboratory records from Kibungo Hospital in 2017. Data were reviewed and collected from March to May, 2018. Logistic regression and odds ratios were calculated to identify the factors associated with neonatal sepsis at 95% CI, p < 0.05. Of the 972 total neonates' medical records from 2017, we randomly selected 422 of which 12.8% (n = 54) had neonatal sepsis. When blood cultures were positive, 62% grew Klebsiella pneumoniae. Among neonates with sepsis, 38 (70%) recovered while 16 (30%) died. Neonatal sepsis was strongly associated with neonatal age less than or equal to three days (aOR: 2.769, 95% CI 1.312-5.843; p = 0.008); and gestational age less than 37 weeks (aOR: 4.149; CI 1.1878-9.167; p ≤ 0.001). Increased use of blood cultures including sensitivity testing, routine surface cultures of the neonatology and maternity wards facilities, and systematic ward cleaning are all important approaches to prevent and treat neonatal infections in additional to regular neonatal sepsis evaluations.

Predictors of mortality among low birth weight neonates after hospital discharge in a low-resource setting: A case study in Uganda

BACKGROUND

Most neonatal deaths occur among low birth weight infants. However, in resource-limited settings, these infants are commonly discharged early which further exposes them to mortality. Previous studies on morbidity and mortality among low birth weight infants after early discharge mainly focused on very low birth weight infants, and none described post-discharge neonatal mortality. This study aimed to determine the proportion and predictors of mortality among low birth weight neonates discharged from the Special Care Baby Unit at Mulago National Referral Hospital in Uganda.

METHODS

This was a prospective cohort study of 220 low birth weight neonates discharged from the Special Care Baby Unit at Mulago National Referral Hospital. These were followed up to 28 completed days of life, or death, whichever occurred first. Proportions were used to express mortality. To determine the predictors of mortality, Cox hazards regression was performed.

RESULTS

Of the 220 enrolled participants, 216 (98.1%) completed the follow-up. The mean gestational age of study participants was 34 ±3 weeks. The median weight at discharge was 1,650g (IQR: 1,315g -1,922g) and 46.1% were small for gestational age. During follow-up, 14/216 (6.5%) of neonates died. Mortality was highest (7/34, 20.6%) among neonates with discharge weights less than 1,200g. The causes of death included presumed neonatal sepsis (10/14, 71.4%), suspected aspiration pneumonia (2/14, 14.3%), and suspected cot death (2/14, 14.3%). The median time to death after discharge was 11 days (range 3-16 days). The predictors of mortality were a discharge weight of less than 1,200g (adj HR: 23.47, p <0.001), a 5-minute Apgar score of less than 7 (adj HR: 4.25, p = 0.016), and a diagnosis of neonatal sepsis during admission (adj HR: 7.93, p = 0.009).

CONCLUSION

Post-discharge mortality among low birth weight neonates at Mulago National Referral Hospital is high. A discharge weight of less than 1,200g may be considered unsafe among neonates. Caregiver education about neonatal danger signs, and measures to prevent sepsis, aspiration, and cot death should be emphasized before discharge and during follow-up visits.

Determinants of Neonatal Sepsis among Neonates Admitted in a Neonatal Intensive Care Unit at Injibara General Hospital, Awi Zone, and Amhara Regional State, Ethiopia

Introduction. Neonatal sepsis is the primary cause of increased newborn morbidity and mortality worldwide, particularly in developing countries. In Ethiopia, the factors of neonatal sepsis are not well understood. Therefore, the purpose of this study was to determine the factors associated with neonatal sepsis in the study area. Methods. A case-control study design was conducted among 60 cases and 120 controls. Variables with P ≤ .25 in the bivariate analysis were entered into multivariable logistic regression, and statistical significance was declared at P < .05. Result. Birth weight <2500-g (AOR = 4.05 [1.44, 11.36], number of ANC visits <3 (AOR = 4.49 [1.70, 11.86], duration of rupture of membrane ≥18 hours (AOR = 4.42; [2.02, 9.66], first minute APGAR score <7 (AOR = 3.09 [1.10, 8.70], birth at a health-center (AOR = 0.22 [0.08, 0.60]) and instrumental delivery (AOR = 0.30 [0.10, 0.88]) were factors associated with neonatal sepsis. Conclusion. Neonatal sepsis was associated with different factors like prolonged membrane rupture, birth weight, and antenatal care visits.

Time to Positivity of Blood Culture as a Predictor of Causative Pathogens and Survival in Neonatal Sepsis: A Retrospective Cohort Study from Indonesia

Objectives

In the blood culture procedure for neonatal sepsis, time to positivity (TTP) reflects the pathogenic bacterial load and the time required for empirical antibiotic regimen administration prior to definitive treatment. This study aims to identify the differences in TTP among causative pathogens and its predictive value for the overall survival of neonates with sepsis at a tertiary healthcare center in Indonesia.

Methods

A retrospective cohort study was conducted from January 2020 to August 2022 at Dr. Soetomo General Hospital, Surabaya, Indonesia. Neonates with blood culture-proven neonatal sepsis were included in the analysis. TTP was defined as the time between the acceptance of a blood culture specimen from the neonatal intensive care unit and reports of positive culture growth by the laboratory.

Results

Across 125 cases, the median TTP was 58.1 hours (IQR = 24.48). Blood cultures were positive within 48 hours for 41.6% of cases, 72 hours for 86.4%, and 96 hours for 98.4%. A significantly shorter TTP was exhibited by the three major gram-negative organisms (Klebsiella pneumoniae,Acinetobacter baumannii,Enterobacter cloacae) compared to coagulase-negative Staphylococci. The neonatal sepsis mortality rate was 49.6% during the study period. In the Cox multivariate regression model, a shorter TTP was an independently predicted mortality in the entire cohort (hazard ratio (HR) = 0.985, 95% CI: 0.973-0.998) and the gram-negative sepsis cohort group (HR = 0.983, 95% CI: 0.968-0.999).

Conclusions

TTP predicts different causative pathogens and the overall survival of neonatal sepsis cases at a tertiary healthcare facility in Indonesia.

Perinatal risk factors for neonatal early-onset sepsis: a meta-analysis of observational studies

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.

Risk factors for neonatal VAP: A retrospective cohort study

Ventilator-associated pneumonia (VAP) is a serious complication in neonates requiring mechanical ventilation. This study aimed to determine the risk factors associated with the development of VAP in neonates admitted to the neonatal intensive care unit (NICU) of the Affiliated Hospital of Southwest Medical University. In a retrospective observational study, neonates admitted to the NICU from 1 January 2019, to 31 December 2021, requiring ventilation for more than 48 h were included. Neonates who died within 48 h of NICU admission, those without obtainable consent, or identified with a genetic syndrome were excluded. Various neonatal and clinical variables were evaluated. Univariate and multivariate analyses were performed to determine risk factors associated with VAP. Of the total neonates included, several risk factors were identified for VAP, such as being a premature infant and use of dexamethasone and sedatives. Moreover, reintubation was found to decrease the risk of VAP. Some factors like gestational age, birth weight, Apgar scores at 5 min, and other parameters were found not significantly associated with the development of VAP. The study identified several risk factors associated with the development of VAP in neonates. Recognizing these risk factors could help in the prevention and early management of VAP, thus improving the prognosis for these patients. Further studies are needed to validate these findings and explore the mechanistic links between these factors and VAP.

miRNAs: novel noninvasive biomarkers as diagnostic and prognostic tools in neonatal sepsis

The study aimed to assess the diagnostic and prognostic value of 3 specific microRNAs (miRNAs) in early-onset neonatal sepsis (NS). We examined miR-1, miR-124, and miR-34a in 70 NS patients upon admission and compared them to 70 healthy controls by RT-PCR. The main finding of the study was the difference in miRNA expression levels between NS patients and controls. Higher expression levels of miR-1 and miR-124 were significantly associated with NS, while miR-34a expression was reduced. Among the studied miRNAs, miR-34a exhibited the highest specificity (97%) as a confirmatory test for NS. In the multivariate model, miR-1 and miR-124 were found to be significant predictors of disease progression or mortality. Overall, the study suggests that miR-1, miR-124, and miR-34a could serve as potential biomarkers for diagnosing and predicting outcomes in early-onset NS.

Epidemiologic Changes of Neonatal Early-onset Sepsis After the Implementation of Universal Maternal Screening for Group B Streptococcus in Hong Kong

BACKGROUND

The epidemiology of neonatal early-onset sepsis (EOS) has changed with time and with changes in prevention strategy. Population-representative contemporary data provide insights on how to further improve EOS prevention and triage strategies.

METHODS

Neonates born in public hospitals in Hong Kong from January 1, 2006, to December 31, 2017 were included. The epidemiological characteristics of EOS and the use of intrapartum antibiotic prophylaxis (IAP) were compared between the 2 epochs before (January 1, 2006 to December 31, 2011) and after (January 1, 2012 to December 31, 2017) the territory-wide implementation of universal maternal group B Streptococcus (GBS) screening.

RESULTS

EOS developed in 1.07‰ of live births (522/490,034). After the implementation of universal GBS screening, the EOS rate decreased in neonates born ≥34 weeks (1.17‰-0.56‰, P < 0.001) and remained similar in those born <34 weeks (7.8‰-10.9‰, P = 0.15), whereas the proportions of IAP coverage increased in both groups [7.6%-23.3% ( P < 0.001) and 28.5%-52.0% ( P < 0.001), respectively]. The major pathogen for EOS shifted from GBS to Escherichia coli , and for early-onset meningitis from GBS to Streptococcus bovis . IAP was associated with subsequent isolation of pathogens resistant to ampicillin [adjusted odds ratio (aOR) 2.3; 95% confidence interval (CI): 1.3-4.2], and second-generation [aOR 2.0; 95% CI: 1.02-4.3] and third-generation [aOR 2.2; 95% CI: 1.1-5.0] cephalosporins.

CONCLUSIONS

Pathogen profile of EOS changed with the implementation of universal GBS screening. S. bovis has emerged as a more common pathogen associated with the risk of meningitis. IAP may not be as effective in reducing EOS rate among infants born <34 weeks as compared with those ≥34 weeks, and newer strategies may be needed.

Determinants of neonatal sepsis among neonates admitted to neonatal intensive care units in ethiopian hospitals: A systematic review and meta-analysis

Objective

Several studies have identified risk factors for neonatal sepsis, but they are limited to specific geographical areas with results that may not be generalizable to other populations. Hence, the objective of this study was to determine the contributing factors, representative at a national level, that influence the occurrence of neonatal sepsis in neonates receiving hospital care in Ethiopia.

Methods and materials

A thorough search was conducted across PubMed/Medline, Hinari, Cochrane Library, and Google Scholar to identify relevant studies. The pooled odds ratio was estimated using the random effect model. The heterogeneity among the included studies was evaluated using the I2 and Cochrane Q-statistics tests. Egger's tests used to assess publication bias.

Results

A total of 19 studies comprising 6190 study participants were included. Neonatal sepsis was positively associated with several factors, namely: prolonged premature rupture of membrane (OR: 3.85, 95% CI: 2.31-6.42), low first minute APGAR score (OR: 3.74, 95% CI: 1.29-10.81), low fifth minute APGAR score (OR: 4.17, 95% CI: 1.76-9.91), delayed initiation of breastfeeding (OR: 3.41, 95% CI: 2.18-5.36), and infection of the maternal urinary tract (OR: 3.17, 95% CI: 1.87-5.35).

Conclusion

Duration of rupture of membrane, APGAR score, time of initiation of breastfeeding, and urinary tract infection have a role in the development of neonatal sepsis.

Neonatal sepsis and its associated factors among neonates admitted to the neonatal intensive care unit in Wachemo University Comprehensive Specialized Hospital, Southern Ethiopia, 2022

Background

Neonatal sepsis is a major public health problem worldwide. It is one of the leading causes of neonatal mortality and morbidity worldwide. The neonatal mortality rate is higher in developing countries, where the extent and causes of neonatal sepsis are not yet known. Neonatal sepsis is a leading cause of neonatal mortality in Ethiopia. As a result, this study aimed to assess the proportion and identify maternal and neonatal risk factors for neonatal sepsis among neonates admitted to the neonatal intensive care unit.

Methods

An institutional-based cross-sectional study was conducted from May 2022 to July 2022 at the Wachemo University Comprehensive Specialized Teaching Hospital, Neonatal Intensive Care Unit, southern Ethiopia. A total of 205 neonates with indexed mothers participated in the study. Using a consecutive sampling technique, a structured, pretested questionnaire was used to collect data from the study subjects. Data were entered into EpiData Manager version 3.1 for Windows and then exported to SPSS version 22 for further data cleaning and analysis. Descriptive analyses were performed by using frequency, percentage, and summary statistics to describe the key variables. A multivariate regression model was used to identify factors associated with neonatal sepsis. Finally, statistical significance was declared at a p-value of less than 0.05, and an adjusted odds ratio (AOR) with a 95% confidence level was used to declare the variable's association with the outcome variable.

Result

The overall prevalence rate of neonatal sepsis was 39.5% (95% CI: 33.7-45.9). Multivariable analysis was performed by taking a variable that is statistically significant in bivariate logistic regression as a candidate variable. Multivariable model analysis showed that unmarried status AOR = 18.37 (95% CI: 1.56-216.14), maternal fever during delivery AOR = 4.74 (95% CI: 1.63-13.8), and premature rupture of membrane AOR = 7.53 (95% CI: 2.19-25.6) were variables that increased the odds of developing neonatal sepsis.

Conclusion

The study's findings indicate that neonatal sepsis is highly prevalent. Unmarried maternal status, maternal fever during delivery, and premature rupture of the membrane were predictors of neonatal sepsis. Therefore, providing training for health workers and close monitoring and evaluation during obstetric and neonatal care are crucial to halt the occurrence of neonatal sepsis.

Prevalence and determinants of early onset neonatal sepsis at two selected public referral hospitals in the Northwest Ethiopia: a cross-sectional study

INTRODUCTION

Globally, neonatal mortality is decreasing, and road maps such as the Early Newborn Action Plan set ambitious targets for 2030. Despite this, deaths in the first weeks of life continue to rise as a percentage of total child mortality. Neonatal sepsis with early onset continues to be a significant cause of death and illness. The majority of sepsis-related deaths occur in developing nations, where the prevalence and causes of newborn sepsis are yet unknown. As a result, the goal of this study was to determine the prevalence of early-onset sepsis and identify determinant factors.

METHODS

A cross-sectional study was conducted on 368 study participants in referral hospitals of East and West Gojjam Zones from March 1^st to April 30^th, 2019. Study participants were selected at random using lottery method. Face-to-face interviews with index mothers for maternal variables and neonatal record review for neonatal variables were used to collect data using a structured pretested questionnaire. Data were entered into Epidata 3.1 and then exported to STATA/SE software version 14. Finally, the logistic regression model was used for analysis. Statistical significance was declared at P < 0.05 after multivariable logistic regression.

RESULTS

A total of 368 newborns and their index mothers took part in this study. The mean age of the newborns was 4.69 days (± 1.93SD). Early-onset neonatal sepsis was seen in 34% of the babies. Nulliparity (AOR: 3.3, 95% CI: 1.1-9.5), duration of labor > 18 h after rupture of membranes (AOR: 11.3, 95% CI: 3.0-41.8), gestational age of 32-37 weeks (AOR: 3.2, 95% CI: 1.2-8.5), and neonates who require resuscitation at birth (AOR: 4, 95% CI: 1.4 -11.8) were all found to be significantly associated with early-onset neonatal sepsis.

CONCLUSION AND RECOMMENDATION

Early-onset neonatal sepsis was found to be high in this study. Early-onset neonatal sepsis was found to be associated with maternal, obstetric, and neonatal variables. Comprehensive prevention strategies that target the identified risk factors should be implemented right away.

Clinical Risk Factors for Early-Onset Sepsis in Neonates: An International Delphi Study

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.

Length of Hospital Stay and Its Predictors Among Neonatal Sepsis Patients: A Retrospective Follow-Up Study

INTRODUCTION

Sepsis is common among neonates, and is often fatal. Hospitalization results in severe nosocomial infections which could be resistant to antibiotics. It also incurs higher fees for medical care.

METHODS

A retrospective follow-up study, which includes 206 neonates, was conducted to assess the length of hospital stay among neonatal sepsis patients from September 2018 to September 2020 at TASH Hospital, Addis Ababa, Ethiopia. Data were collected from medical charts. Mean length of hospital stay was compared using independent sample t-tests. Risk factors for length of stay were identified using binary logistic regression analysis.

RESULTS

All neonates stayed a total of 325 days, which gives 75,512 neonate-days. Neonates who stayed more than 7 days had low mean birth weight and higher mean age at admission. Mean length of stay was higher among neonates with comorbid illness, neonates with drug therapy problems and male neonates. Even though the mean length of stay is shorter among neonates with maternal PROM and CS delivery, these maternal factors were found to be insignificant in the multivariate logistic regression.

DISCUSSION

Similar to other studies, neonates with low birth weight and comorbidity had a longer hospital stay. Neonates with maternal PROM and CS delivery had a shorter stay. But these maternal factors, identified by prior studies as risk factors for neonatal sepsis and its mortality, are not found to be predictors of prolonged hospitalization. Having neurologic features and drug therapy problems among neonates with sepsis prolonged hospital stay.

CONCLUSION

The mean length of stay varies with respect to maternal and neonatal factors. Lower birth weight, presence of neurologic features, presence of comorbidity, presence of drug therapy problems and being male are found to be predictors of a longer hospital stay among neonates with sepsis.

Clinical and laboratory factors associated with neonatal sepsis mortality at a major Vietnamese children's hospital

Sepsis is a major cause of neonatal mortality and children born in low- and middle-income countries (LMICs) are at greater risk of severe neonatal infections than those in higher-income countries. Despite this disparity, there are limited contemporaneous data linking the clinical features of neonatal sepsis with outcome in LMICs. Here, we aimed to identify factors associated with mortality from neonatal sepsis in Vietnam. We conducted a prospective, observational study to describe the clinical features, laboratory characteristics, and mortality rate of neonatal sepsis at a major children's hospital in Ho Chi Minh City. All in-patient neonates clinically diagnosed with probable or culture-confirmed sepsis meeting inclusion criteria from January 2017 to June 2018 were enrolled. We performed univariable analysis and logistic regression to identify factors independently associated with mortality. 524 neonates were recruited. Most cases were defined as late-onset neonatal sepsis and were hospital-acquired (91.4% and 73.3%, respectively). The median (IQR) duration of hospital stay was 23 (13-41) days, 344/524 (65.6%) had a positive blood culture (of which 393 non-contaminant organisms were isolated), and 69/524 (13.2%) patients died. Coagulase-negative staphylococci (232/405; 57.3%), Klebsiella spp. (28/405; 6.9%), and Escherichia coli (27/405; 6.7%) were the most isolated organisms. Sclerema (OR = 11.4), leukopenia <4,000/mm3 (OR = 7.8), thrombocytopenia <100,000/mm3 (OR = 3.7), base excess < -20 mEq/L (OR = 3.6), serum lactate >4 mmol/L (OR = 3.4), extremely low birth weight (OR = 3.2), and hyperglycaemia >180 mg/dL (OR = 2.6) were all significantly (p<0.05) associated with mortality. The identified risk factors can be adopted as prognostic factors for the diagnosis and treatment of neonatal sepsis and enable early risk stratification and interventions appropriate to reduce neonatal sepsis in LMIC settings.

Time to recovery of neonatal sepsis and determinant factors among neonates admitted in Public Hospitals of Central Gondar Zone, Northwest Ethiopia, 2021

Background

Neonatal sepsis is a leading cause of neonatal morbidity and mortality, particularly in developing countries. Time to recovery is an indicator of the severity of sepsis, and risk factors varied significantly according to study population and settings. Moreover, published literature regarding the time to recovery of neonatal sepsis is scarce.

Objective

The aim of this study was to assess the time to recovery of neonatal sepsis and determinant factors among neonates admitted in the Public Hospitals of Central Gondar Zone, Northwest Ethiopia.

Methods

An institution-based prospective follow-up study design was conducted among 631 neonates with sepsis. A structured, pre-tested, interviewer-administered questionnaire was used. The median time to recovery, life-table, the Kaplan Meier curve, and the log-rank test were computed. Both bi-variable and multivariable Cox regression models were applied to analyze the data.

Results

Of all septic neonates, 511 successfully recovered. They were followed for a total of 4,740-neonate day’s observation and the median time to recovery was 7 days (IQR = 5–10 days). After adjusting for covariates, intrapartum fever (AHR = 0.69, 95%CI: 0.49, 0.99), induced onset of labor (AHR = 0.68, 95%CI: 0.49, 0.94), chest indrawing (AHR = 0.67, 95%CI: 0.46, 0.99), late onset sepsis (AHR = 0.55, 95%CI: 0.40, 0.75), non-oral enteral feeding (AHR = 0.38, 95%CI: 0.29, 0.50), assisted with bag and mask (AHR = 0.72, 95%CI: 0.56, 0.93), normal birth weight (AHR = 1.42, 95%CI: 1.03, 1.94), gestational age of 37–42 weeks (AHR = 1.93, 95%CI: 1.32, 2.84), septic shock (AHR = 0.08, 95%CI: 0.02, 0.39), infectious complications (AHR = 0.42, 95%CI: 0.29, 0.61), being in critical conditions (AHR = 0.68, 95%CI: 0.52, 0.89), and early recognition of illness (AHR = 1.83, 95%CI: 1.27, 2.63) were independently associated with the time to recovery of neonatal sepsis.

Conclusions and recommendations

The time to recovery of this study was moderately acceptable as compared to the previous studies. The above-mentioned factors could be used for the early identification of neonates with sepsis at risk for protracted illness and it could guide prompt referral to higher centers in primary health sectors. This also will provide prognostic information to clinicians and families as longer recovery time has economic and social implications in our country.

Contemporary Trends in Global Mortality of Sepsis Among Young Infants Less Than 90 Days: A Systematic Review and Meta-Analysis

Objective

Current knowledge on the global burden of infant sepsis is limited to population-level data. We aimed to summarize global case fatality rates (CFRs) of young infants with sepsis, stratified by gross national income (GNI) status and patient-level risk factors.

Methods

We performed a systematic review and meta-analysis on CFRs among young infants < 90 days with sepsis. We searched PubMed, Cochrane Central, Embase, and Web of Science for studies published between January 2010 and September 2019. We obtained pooled CFRs estimates using the random effects model. We performed a univariate analysis at patient-level and a meta-regression to study the associations of gestational age, birth weight, onset of sepsis, GNI, age group and culture-proven sepsis with CFRs.

Results

The search yielded 6314 publications, of which 240 studies (N = 437,796 patients) from 77 countries were included. Of 240 studies, 99 were conducted in high-income countries, 44 in upper-middle-income countries, 82 in lower-middle-income countries, 6 in low-income countries and 9 in multiple income-level countries. Overall pooled CFR was 18% (95% CI, 17-19%). The CFR was highest for low-income countries [25% (95% CI, 7-43%)], followed by lower-middle [25% (95% CI, 7-43%)], upper-middle [21% (95% CI, 18-24%)] and lowest for high-income countries [12% (95% CI, 11-13%)]. Factors associated with high CFRs included prematurity, low birth weight, age less than 28 days, early onset sepsis, hospital acquired infections and sepsis in middle- and low-income countries. Study setting in middle-income countries was an independent predictor of high CFRs. We found a widening disparity in CFRs between countries of different GNI over time.

Conclusion

Young infant sepsis remains a major global health challenge. The widening disparity in young infant sepsis CFRs between GNI groups underscore the need to channel greater resources especially to the lower income regions.

Magnitude and associated factors of neonatal sepsis among neonates admitted to neonatal intensive care unit of Northern oromia hospitals, Ethiopia: A multicenter cross-sectional study

Background

Globally sepsis is the most cause of neonatal death. Neonatal sepsis is the major newborn killer in Ethiopia, which accounts for more than one-third of neonatal deaths. Therefore, the study was aimed to assess the prevalence and associated factors of neonatal sepsis.

Methods

An institutional based cross-sectional study was employed on a total of 378 neonates admitted to the NICU of selected four hospitals. It was conducted from January 2021 to March 2021. Multivariate logistic regression analysis was used to determine the prevalence of neonatal sepsis.

Results

Among neonates who enrolled in this study 188(50.1%) of them were females and 283 (75.5%) of them were in the age group of early neonatal period. The overall magnitude of neonatal sepsis in this study was 196(52.27%). From this 159(81.12%) and 37(18.88%) of neonates developed early onset neonatal sepsis and late onset neonatal sepsis, respectively. Factors such as age of neonates[AOR = 2.351, 95% CI (1.131, 4.888)], birth weight of neonate less than 2.5 kg[AOR = 2.546, 95% CI (1.875, 3.643)], multiple per digital vaginal examination[AOR =0.278, 95% CI (0.148,0.522)], history of urinary tract infection[AOR = 3.709, 95% CI (1.828–7.301)], Meconium stained amniotic fluid (MSAF)[AOR = 0.384, 95% CI (0.152, 0.968)] and intrapartum high fever[AOR = 2.203, 95% CI (1.034, 4.692)] were the independent determinants of neonatal sepsis.

Conclusion

This study indicated that the magnitude of neonatal sepsis was found to be high. In general, this study has found that both maternal and neonatal factors had contributed to the risk of neonatal sepsis. Based on these results we recommend the healthcare providers to focus on the prevention of risk factors rather than treating the disease after it occurs.

In a developing countries accurate diagnosis of neonatal sepsis is not satisfactory.

Untargeted 1H-NMR Urine Metabolomic Analysis of Preterm Infants with Neonatal Sepsis

One of the most critical medical conditions occurring after preterm birth is neonatal sepsis, a systemic infection with high rates of morbidity and mortality, chiefly amongst neonates hospitalized in Neonatal Intensive Care Units (NICU). Neonatal sepsis is categorized as early-onset sepsis (EOS) and late-onset sepsis (LOS) regarding the time of the disease onset. The accurate early diagnosis or prognosis have hurdles to overcome, since there are not specific clinical signs or laboratory tests. Herein, a need for biomarkers presents, with the goals of aiding accurate medical treatment, reducing the clinical severity of symptoms and the hospitalization time. Through nuclear magnetic resonance (NMR) based metabolomics, we aim to investigate the urine metabolomic profile of septic neonates and reveal those metabolites which could be indicative for an initial discrimination between the diseased and the healthy ones. Multivariate and univariate statistical analysis between NMR spectroscopic data of urine samples from neonates that developed EOS, LOS, and a healthy control group revealed a discriminate metabolic profile of septic newborns. Gluconate, myo-inositol, betaine, taurine, lactose, glucose, creatinine and hippurate were the metabolites highlighted as significant in most comparisons.

Predictors of mortality among neonates hospitalized with neonatal sepsis: a case control study from southern Ethiopia

Background

Neonatal sepsis, which resulted from bacterial, viral, and fungal invasions of the bloodstream, is the major cause of neonatal mortality and neurodevelopmental impairment among neonates. It is responsible for more than one-third of neonatal deaths in Ethiopia. Frequently neonates referred to health facilities are at high risk of death. Hence, assessing and preventing the predictors of mortality in neonatal sepsis helps to reduce the burden of neonatal mortality.

Objectives

To determine predictors of mortality among neonates admitted with sepsis at Durame general hospital, southern Ethiopia, 2020.

Methods

Institution-based unmatched case-control study was carried out from March 8 to 30, 2020, among 219 neonates in Durame general hospital in southern Ethiopia. Neonates admitted with sepsis and died were considered as cases and neonates admitted with sepsis and survived (discharged alive) as controls. Cases were selected by taking the deaths of neonates consecutively among those neonates admitted with the diagnosis of neonatal sepsis. The next immediate three corresponding controls were selected by lottery method from the Neonatal Intensive Care Unit (NICU) case registration book. Data was collected by using structured pretested checklists from neonates’ records and then entered into Epi data version 3.1 and exported to SPSS version 20. Logistic regression was used to identify the predictors of mortality. Statistical significance was declared at P < 0.05.

Results

A total of 55 cases and 164 controls were included in this study. More than three quarters (81.8%) of cases had early onset sepsis. The multivariable logistic regression analysis showed that predictors of mortality in this study were; poor feeding [AOR = 4.15; 95% CI (1.64, 10.49)], respiratory distress [AOR = 2.72; 95% CI (1.31, 5.61)], estimated gestational age less than 37 weeks [AOR = 4.64; 95% CI (2.17, 9.91)], and convulsion [AOR = 3.13; 95% CI (1.12, 8.76)].

Conclusion

This study showed that prematurity, convulsion, poor feeding, and respiratory distress were the predictors of sepsis-related neonatal mortality. It is important to pay attention to septicemic babies with any of the identified predictors to reduce sepsis-related mortality.

Incidence of emerging multidrug-resistant organisms and its impact on the outcome in the pediatric intensive care

Background

Healthcare-associated infections (HCAI) are a worldwide threat in intensive care units particularly in the pediatric intensive care units with a major cause of morbidity and mortality among this age group. The aim of the study is to determine the prevalence and risk factors predisposing to multidrug-resistant organisms (MDROs) infections among pediatric intensive care unit (PICU) patients at Ain Shams Pediatric University Hospitals as well as determining mortality and morbidity rates along with the length of stay at PICU.

Results

Culture results revealed that of the 282 patients evaluated, only 26 (9.2%) were MDROs (half of the affected patients had Acinetobacter species (50%) and the rest of them were free, 256 (90.8%). Our study revealed that the majority of MDROs were isolated from sputum in more than half of the patients 19/32 (59.3%) followed by whole blood in 10/32 (31.2%) and urine in 3/32 (9.4%). Pulmonary system was the most common affected site and was mainly colonized by MDR Acinetobacter (71.4%) followed by MDR Klebsiella (41.6%). Regarding MDR risk factors in our PICU, multivariate logistic regression analyses showed significant relationship between MDROs and age under 1 year (odds ratio [OR] 2.4554; 95% confidence interval [95% CI] (1.072–5.625); p = 0.043) and underlying pulmonary disease (OR 2.417; 95% CI (1.014–5.761); p = 0.592). A statistically significant higher mortality was detected in patients colonized with MDROs 9/26 (34.6%) versus MDROs non-colonized patients 32/256 (12.5%) [P=0.002]. Moreover, MDROs infection has negative significant risk with discharged patients ([OR] 0.269; [95% CI] (0.111–0.656); p = 0.002). Additionally, patients infected with MDROs did have significantly greater PICU stay than those non-infected [median (IQR), 16.5 (10.7–22), 5 (4–8), P=0.00] and have longer ventilation [median (IQR), 15.5 (10–18), 3 (2–10), P=0.00].

Conclusion

Prevalence of MDROs (9.2%) was low among PICU cases at Ain Shams University Hospitals. Most common MDROs were Acinetobacter and Klebsiella followed by pseudomonas species. The frequency of gram-negative organisms is much more common than gram-positive organisms. An increasing rate of antimicrobial resistance with increasing mortality and morbidity among PICU patients is observed worldwide; even for new categories, so, strict infection control programs should be implemented.

Trend Analysis of Multidrug-Resistant Bacterial Pathogens Causing Neonatal Sepsis at University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia: A Retrospective Study

Background

Neonatal sepsis is the most common cause of mortality and morbidity. It is a major global public health challenge, particularly in developing countries. Therefore, knowing the current status of bacterial isolates and their antimicrobial resistance profile is essential to physicians and health workers to implement appropriate intervention. The aims of this study was to assess a ten-year trend of bacterial prevalence isolates from blood culture among neonates (<1 month of age).

Method

A hospital-based retrospective study was conducted on 1854 neonatal patients who were admitted at University of Gondar Specialized Comprehensive Hospital between 2010 and 2020. Sociodemographical and laboratory data were collected from medical records. Quality of the data was assured through standard operational procedures. Data were entered and analysed using SPSS version 20. Bivariate analysis was employed to determine strings of association between the outcome variable and sociodemographic variables. A P value less than 0.05 will be considered to be statically significant.

Results

In a total of 1854 patients, 538 (29%) were culture positive. The overall neonatal sepsis infection rate was 287 (53.5%) for male and 249 (46.5%) for female. The highest proportion of neonatal sepsis infection rate was observed among the patients in the age range between 3 and 28 days and gestational at birth <37 weeks, 461(86%) and 278 (52%), respectively. Gestational at birth (P ≤ 0.001, AOR = 5.81, CI: 4.63–7.29) is significantly associated with bacterial isolates. The predominant pathogens were Staphylococcus aureus, 18 (76.6%), Klebsiella pneumoniae, 146 (38%), and E. coli, 45 (11.7%) among the age range less than one weak. Klebsiella spp, S. aureus, and E. coli showed a high level of resistance to most tested antimicrobials. Amikacin, ciprofloxacin and norfloxacin, and erythromycin were the most effective antibiotics whereas ampicillin, amoxicillin, and cotrimoxazole were the least effective antibiotics for isolates.

Conclusion

Neonatal sepsis infection is common in the 3–28 days of age range. S. aureus, E. coli, and K. pneumonia were the most common isolates. Most the bacterial pathogens were resistant to commonly prescribed antibiotics. Therefore, an antimicrobial sensitivity test for bacterial isolates is recommended to provide updated data for the physician in choosing the appropriate antibiotic for better patient treatment outcome.

Methicillin and multidrug resistant pathogenic Staphylococcus aureus associated sepsis in hospitalized neonatal infections and antibiotic susceptibility

BACKGROUND

Neonatal infection is infection of the newborn or neonate acquired in first four weeks of life or during prenatal development. Microorganism associated neonatal infections caused severe mortality in recent years. It is developed either prenatally or within 28 days of neonatal period. This infection is mainly transmitted from mother to child through placenta. It has been well associated with the premature rupture of membranes which markedly enhances the risk of neonatal sepsis.

METHODS

The present experiment was designed to analyze bacteria, their antibiotic resistance pattern and possible risk factors among neonatal patients with sepsis. The neonates specimen was subjected for the isolation of bacteria and antibiotic susceptibility test. Neonates were analyzed with previous clinical history such as, previous admission in hospitals, mode of delivery, birth weight, and feeding type in accordance with questionnaire.

RESULTS

Gram-positive bacteria isolates were found to be high (79 strains, 64.22%) than the Gram-negative bacteria (44 strains, 32.5%). Staphylococcus aureus (33 strains, 26.9%) was the major Gram-positive groups of bacteria. Multidrug resistance analysis accounted more S. aureus (26.9%) and 5 strains (15.15%) showed methicillin resistance, whereas 84.9% were found to be sensitive to methicillin.

CONCLUSION

In this study, S. aureus and K. pneumoniae were the highest frequency of isolates. The overall percentage of multidrug resistant isolates was high in this study. Highest degree of resistance was observed in ampicillin against all isolates. Hence much attention is required while diagnosing sepsis among neonates. To analyze the risk for neonatal sepsis, it is not preferable for caesarian mode of delivery. Moreover, frequent screening of mother, suitable prenatal care of newborns with proper clinical interventions isthe key elements to control sepsis.

Risk Factors for Neonatal Sepsis in Secondary and Tertiary Care Hospitals of a District in Sri Lanka: A Case–Control Study

Objective The aim of this study was to determine the risk factors for neonatal sepsis.

Methods A case–control study was performed in secondary and tertiary care hospitals of a district in Sri Lanka. Neonates who diagnosed with sepsis based on clinical criteria or culture positivity were taken as the case group (n = 240) and neonates born during the same period who had not been diagnosed with sepsis were taken as the control group (n = 240). The controls were recruited from the community. The study instruments were, pretested interviewer administered questionnaire, a check list and record sheets. Multiple logistic regression analysis was performed. The results were expressed as odds ratios (OR) with the 95% confidence intervals (CI).

Results The independent risk factors for neonatal sepsis were history of abortions, still birth, and early neonatal deaths (OR: 6.78; 95% CI: 3.2–14.3), registration of pregnancy after 8 weeks of gestation (OR: 1.91; 95% CI: 1.07–3.4), total antenatal clinic visits ≤4 (OR: 7.18; 95% CI: 2.1–24.5), history of maternal fever prior to the week of delivery (OR: 2.74; 95% CI: 1.25–6.0) leaking amniotic fluid >18 hours (OR: 10.0; 95% CI: 2.1–47.4), performed >3 vaginal examinations before delivery (OR: 3.28; 95% CI: 2.1–24.5), meconium stained amniotic fluid (OR: 10.57; 95% CI: 3.7–29.7), mode of delivery by cesarean section, forceps or vacuum (OR: 2.33; 95% CI: 1.4–3.9), time of birth of the neonate being during on-call hours (OR: 2.12; 95% CI: 1.3–3.5), being a male baby (OR: 1.74; 95% CI: 1.1–2.8), and birth weight <2,500 g (OR: 5.17; 95% CI: 2.8–9.6) of neonates.

Conclusion Most of the identified risk factors for neonatal sepsis were modifiable. Stringent implementation of guidelines and protocols would prevent neonatal sepsis.

A Systemic Review and Meta-analysis of the Leading Pathogens Causing Neonatal Sepsis in Developing Countries

Background

Neonatal sepsis is one of the major public health problems globally, particularly, in developing countries. Klebsiella, Staphylococcus aureus, Coagulase-negative Staphylococcus, and Escherichia coli are the common pathogens for neonatal sepsis in developing countries. However, the pooled estimate of common pathogens causing neonatal sepsis in developing countries is still unknown. Therefore, this study is aimed at computing the pooled proportion of the leading cause of pathogens for neonatal sepsis in developing countries.

Methods

We strictly followed the Preferred Reporting Items for Systemic Reviews and Meta-analysis guidelines to report this systematic review and meta-analysis. PubMed, Cochrane Library, Web of Science, CINAHL, Science Direct, and other search engines such as Google Scholar, Africa Journals Online, and Hinari were used to obtain studies related to the leading cause of pathogens for neonatal sepsis in developing countries. The search was done from October 1 to December 30, 2018, by considering both published and gray literature. Studies were evaluated based on the PRISMA guideline checklist by using their titles, abstracts, and full texts. Studies were extracted using Microsoft Excel spreadsheets, and STATA software version 14 was used to analyze data. Heterogeneity between studies was checked based on Cochran's Q-test and the corresponding I² statistic test.

Results

The pooled prevalence of the leading cause of pathogens of neonatal sepsis in developing countries were Klebsiella (26.36%), Staphylococcus aureus (23.22%), Coagulase-negative Staphylococcus (23.22%), and Escherichia coli (15.30%). Common pathogens were varied across regions; for instance, pooled isolated Coagulase-negative Staphylococcus was 25.98% in Africa, 16.62% in Asia, and 36.71% in Latin America, and Klebsiella was 29.80% in Africa, 23.21% in Asia, and 22.00% in Latin America. Also, Staphylococcus aureus was 27.87% in Africa and 18.28% in Asia, and Escherichia coli was 22.97% in Asia and 9.43% in Africa.

Conclusions

This study highlights that the more prevalent common isolated pathogens in developing countries were Klebsiella, Staphylococcus aureus, Coagulase-negative Staphylococcus, and Escherichia coli, Klebsiella, and Staphylococcus aureus pathogens were predominantly high in Africa as compared to other Asian and Latin American countries. At the same time, Coagulase-negative Staphylococcus was more prevalent in Latin America compared to other regions. Escherichia coli is more dominant in Asia as compared to Africa and Latin America.

Antibiotic regimens for late-onset neonatal sepsis

BACKGROUND

Neonatal sepsis is a major cause of morbidity and mortality. It is the third leading cause of neonatal mortality globally constituting 13% of overall neonatal mortality. Despite the high burden of neonatal sepsis, high-quality evidence in diagnosis and treatment is scarce. Due to the diagnostic challenges of sepsis and the relative immunosuppression of the newborn, many neonates receive antibiotics for suspected sepsis. Antibiotics have become the most used therapeutics in neonatal intensive care units, and observational studies in high-income countries suggest that 83% to 94% of newborns treated with antibiotics for suspected sepsis have negative blood cultures. The last Cochrane Review was updated in 2005. There is a need for an updated systematic review assessing the effects of different antibiotic regimens for late-onset neonatal sepsis.

OBJECTIVES

To assess the beneficial and harmful effects of different antibiotic regimens for late-onset neonatal sepsis.

SEARCH METHODS

We searched the following electronic databases: CENTRAL (2021, Issue 3); Ovid MEDLINE; Embase Ovid; CINAHL; LILACS; Science Citation Index EXPANDED and Conference Proceedings Citation Index - Science on 12 March 2021. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-RCTs.

SELECTION CRITERIA

We included RCTs comparing different antibiotic regimens for late-onset neonatal sepsis. We included participants older than 72 hours of life at randomisation, suspected or diagnosed with neonatal sepsis, meningitis, osteomyelitis, endocarditis, or necrotising enterocolitis. We excluded trials that assessed treatment of fungal infections.

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed studies for inclusion, extracted data, and assessed risk of bias. We used the GRADE approach to assess the certainty of evidence. Our primary outcome was all-cause mortality, and our secondary outcomes were: serious adverse events, respiratory support, circulatory support, nephrotoxicity, neurological developmental impairment, necrotising enterocolitis, and ototoxicity. Our primary time point of interest was at maximum follow-up.

MAIN RESULTS

We included five RCTs (580 participants). All trials were at high risk of bias, and had very low-certainty evidence. The five included trials assessed five different comparisons of antibiotics. We did not conduct a meta-analysis due to lack of relevant data. Of the five included trials one trial compared cefazolin plus amikacin with vancomycin plus amikacin; one trial compared ticarcillin plus clavulanic acid with flucloxacillin plus gentamicin; one trial compared cloxacillin plus amikacin with cefotaxime plus gentamicin; one trial compared meropenem with standard care (ampicillin plus gentamicin or cefotaxime plus gentamicin); and one trial compared vancomycin plus gentamicin with vancomycin plus aztreonam. None of the five comparisons found any evidence of a difference when assessing all-cause mortality, serious adverse events, circulatory support, nephrotoxicity, neurological developmental impairment, or necrotising enterocolitis; however, none of the trials were near an information size that could contribute significantly to the evidence of the comparative benefits and risks of any particular antibiotic regimen. None of the trials assessed respiratory support or ototoxicity. The benefits and harms of different antibiotic regimens remain unclear due to the lack of well-powered trials and the high risk of systematic errors.

AUTHORS' CONCLUSIONS

Current evidence is insufficient to support any antibiotic regimen being superior to another. RCTs assessing different antibiotic regimens in late-onset neonatal sepsis with low risks of bias are warranted.

Study of Antibiotic Susceptibility among Bacterial Isolates in Neonatal Intensive Care Unit of a Tertiary Care Hospital: A Descriptive Cross-sectional Study

Introduction:

Neonatal sepsis is a major cause of neonatal morbidity and mortality worldwide, especially in developing countries like Nepal. Antibiotic resistance among microorganisms poses new challenges in the treatment of neonatal sepsis. The present study is conducted with the objectives of determining clinico-bacteriological profile and antibiotic susceptibility among isolated bacteria in a neonatal intensive care unit.

Methods:

A descriptive cross-sectional study was conducted from January 1, 2017, to December 31, 2019, in the neonatal intensive care unit of a tertiary care hospital after obtaining ethical clearance from Institutional Review Committee (Ref: 2020-064). The sample size was calculated and 77 neonates with culture-proven sepsis were included in the study. The antibiotic susceptibility tests of the isolates were done by Kirby-Bauer disc diffusion method. Data entry was done in Statistical Packages for the Social Sciences version 20.

Results:

Of the 841 specimens (blood, cerebrospinal fluid, urine, tracheal aspirate and pus) processed for culture, bacteria were isolated in 84 (10.0%) specimens. Among the 84, gram-negative bacilli were the predominant isolates 76 (90.5%); of which Acinetobacter baumannii was the most common 27 (32.1%). Both the Gram-negative and the Gram-positive bacteria showed high resistance to Penicillin and Cephalosporins. Gram-negative bacteria showed maximum sensitivity to Colistin, Carbapenems, Tigecycline and Fluoroquinolones. Gram-positive bacteria showed maximum susceptibility to Amikacin, Vancomycin and Carbapenems.

Conclusions:

Judicious use of antibiotics based on the updated knowledge of prevalent organisms in the local hospital setting and their antibiotic sensitivity pattern is of utmost importance for the effective treatment of neonatal sepsis.

Predictors of Neonatal Sepsis in Hospitals at Wolaita Sodo Town, Southern Ethiopia: Institution-Based Unmatched Case-Control Study, 2019

Background

Neonatal sepsis plays a significant role in neonates' mortality in developing countries accounting for 30-50% of total deaths each year. Gaining insight into neonatal sepsis predictors will provide an opportunity for the stakeholders to reduce the causes of neonatal sepsis. This research is aimed at determining the predictors of neonatal sepsis at Wolaita Sodo University Teaching Referral Hospital and Sodo Christian General Hospital, Ethiopia, April-July 2019.

Method

This study employed an institution-based unmatched case-control study by selecting neonates in selected hospitals through consecutive sampling technique. The cases of this study are neonates diagnosed with sepsis. The study used a pretested structured questionnaire for a face-to-face interview to collect data from index mothers. Besides, the review of the record was done using checklists. The data were entered into EpiData version 3.1 and exported to Statistical Package for the Social Sciences version 24.0 for analysis. The study used descriptive, bivariate, and multivariate analyses. The odds ratio with 95% confidence interval was used to measure the association's strength. p < 0.05 was the cut-off point for declaration of statistical significance for the multivariate analysis.

Results

Factors significantly associated with neonatal sepsis among neonates were maternal age of 15-20 years and 21-30 years, mothers with low income/wealth, history of urinary tract infections/sexually transmitted infections, presence of intrapartum infections, antenatal care follow‐up < 3 visits, Apgar (Appearance, Pulse, Grimace, Activity, and Respiration) score < 7, low birth weight, and the time in which breastfeeding started after delivery < 60 minutes.

Conclusion

Maternal age, wealth/income, maternal urinary tract infections/sexually transmitted infections, intrapartum fever, antenatal care visit ≤ 3 times, Apgar score < 7, low birth weight, and starting time of breastfeeding were independent predictors of neonatal sepsis. Therefore, maternal health education during antenatal care visits, perinatal and newborn care, and early initiation of breastfeeding might decrease neonatal mortality and morbidity due to sepsis.

Neonatal sepsis and its associated factors in East Africa: a systematic review and meta-analysis

OBJECTIVES

This systematic review and meta-analysis aimed to reveal the magnitude of neonatal sepsis and its associated factors in East Africa.

METHODS

Using PRISMA guideline, we reviewed and meta-analyzed studies from Google Scholar, Cochrane library, and PubMed; last search date: October 15, 2019. Heterogeneity across the studies was estimated. The subgroup analysis was done. Publication bias was also assessed.

RESULTS

A total of 26 studies with 11,239 participants are included. The pooled prevalence of neonatal sepsis in East Africa was 29.765% (95% CI 23.36-35.94). Home delivery (AOR = 2.67; 95% CI 1.15-4.00), maternal history of urinary tract infection (UTI) (AOR = 2.083; 95% CI 0.24-3.93), gestational age/(preterm) (AOR = 1.56; 95% CI 1.04-2.08), prolonged labor (AOR = 3.23; 95% CI 0.04-6.51) and PROM (AOR = 1.95; 95% CI 0.53-3.37) were identified associated factors of neonatal sepsis.

CONCLUSIONS

The prevalence of neonatal sepsis in East Africa remains high. The relevant stockholders should give attention for neonates delivered from women with intranatal fever to prevent neonatal sepsis. Pregnant women should be screened for UTI. Appropriate interventions should be put in place to manage PROM to decrease the chance of ascending microorganisms.

Valuable Role of Neutrophil CD64 and Highly Sensitive CRP Biomarkers for Diagnostic, Monitoring, and Prognostic Evaluations of Sepsis Patients in Neonatal ICUs

Background

Neonatal sepsis (NS) is a very critical medical situation associated with high morbidities and mortalities. There is an utmost need for a new tool helping in early diagnosis and proper management of sepsis neonates. Neutrophil CD64 (nCD64) shows a very promising value in this concerning issue.

Aim

Evaluate the diagnostic, monitoring, and prognostic performances of nCD64 and highly sensitive CRP (hs-CRP) in NS as well as the possible best panel of biomarkers that can achieve the most desirable results.

Methods

Patients were enrolled from three neonatal intensive care units (NICUs) (n = 121 patients) and classified according to their initial sepsis evaluation into three groups: disease control group (n = 30), proven sepsis group (n = 17), and clinical sepsis group (n = 74). Laboratory evaluation included hs-CRP, complete blood count (CBC), and blood culture in addition to nCD64 (done by flow cytometry technique). Besides the diagnostic evaluations, follow-up evaluations were done for 40 patients after five days from the first time; patients were reclassified according to their outcome into the improved sepsis neonates' group (n = 26) and sepsis neonates without improvement (n = 14).

Results

Significant increase in nCD64 and hs-CRP results were present in sepsis groups compared to the disease controls (P < 0.001); nCD64 at 43% cutoff value could detect the presence of sepsis with 85.6% sensitivity and 93% specificity. Additionally, delta change percentage (dC%) between improved sepsis neonates and sepsis neonates without improvement showed a significant difference in the levels of both nCD64 (P < 0.001) and hs-CRP (P = 0.001).

Conclusion

Besides the promising diagnostic performance documented by nCD64 which is higher than the other laboratory sepsis biomarkers used routinely in NICUs, nCD64 has a valuable role in sepsis patients' monitoring and prognostic evaluation. hs-CRP was moderate in its diagnostic and monitoring results being less than that achieved by nCD64. Combined measurement of nCD64% and hs-CRP gives better diagnostic and monitoring performance than that achieved by any of them alone.

Predictors of neonatal sepsis in public referral hospitals, Northwest Ethiopia: A case control study

BACKGROUND

Despite remarkable progress in the reduction of death in under-five children, neonatal mortality has shown little or no concomitant reduction globally. It is also one of the most common causes of neonatal death in Ethiopia. Little is known on predictors of neonatal sepsis. Risk based screening and commencement of treatment appreciably reduces neonatal death and illness. Therefore, the main aim of this study was to identify predictors of neonatal sepsis in public referral hospitals of Northwest Ethiopia.

METHODS

Institutional based unmatched case-control study was conducted among a total of 231 neonates in Debre Markos and Felege Hiwot referral hospitals from March 2018- April 2018. Neonates who fulfill the preseted criteria for sepsis were considered as cases and neonates diagnosed with other medical reasons except sepsis were controls. For each case, two consecutive controls were selected by simple random sampling method. Data were collected using structured pretested questionnaire through a face to face interview with index mothers and by reviewing neonatal record using checklist. The collected data were entered into Epi data version 3.1 and exported to STATA/ SE software version 14. Binary and multivariable logistic regression analyses were employed. Statistical significance was declared at P<0.05.

RESULT

Multivariable logistic regression analysis showed that, duration of rupture of membrane ≥ 18hours was significantly associated with sepsis (AOR = 10.4, 95%CI = 2.3-46.5). The other independent predictors of neonatal sepsis were number of maternal antenatal care service ≤3 (AOR = 4.4, 95%CI = 1.7-11.5), meconium stained amniotic fluid (AOR = 3.9, 95%CI = 1.5-9.8), urinary tract infection during pregnancy (AOR = 10.8, 95% CI = 3.4-33.9), intranatal fever (AOR = 3.2, 95% CI = 1.1-9.5), first minute APGAR score <7 (AOR = 3.2, 95% CI = 1.3-7.7), resuscitation at birth (AOR = 5.4, 95% CI = 1.9-15.5), nasogastric tube insertion (AOR = 3.7, 95% CI = 1.4-10.2).

CONCLUSION

Neonatal invasive procedures, ANC follow up during pregnancy, different conditions during birth like meconium stained amniotic fluid, low APGAR score and resuscitation at birth were the independent predictors of neonatal sepsis.

Neonatal Sepsis

Neonatal sepsis is associated with severe morbidity and mortality in the neonatal period. Clinical manifestations range from subclinical infection to severe local or systemic infection. Neonatal sepsis is divided into three groups as early-onset neonatal sepsis, late-onset neonatal sepsis and very late-onset neonatal sepsis according to the time of the onset. It was observed that the incidence of early-onset neonatal sepsis decreased with intrapartum antibiotic treatment. However, the incidence of late-onset neonatal sepsis has increased with the increase in the survival rate of preterm and very low weight babies. The source of the causative pathogen may be acquisition from the intrauterine origin but may also acquisition from maternal flora, hospital or community. Prematurity, low birth weight, chorioamnionitis, premature prolonged rupture of membranes, resuscitation, low APGAR score, inability to breastfeed, prolonged hospital stay and invasive procedures are among the risk factors. This article reviews current information on the definition, classification, epidemiology, risk factors, pathogenesis, clinical symptoms, diagnostic methods and treatment of neonatal sepsis.

CLINICAL AND MICROBIOLOGICAL FEATURES OF EARLY-ONSET NEONATAL SEPSIS IN PRETERM INFANTS

Early-onset neonatal sepsis (EONS) remains the leading cause of morbidity and mortality, especially among premature infants. Conducting high-quality epidemiological monitoring is an important condition for effective tactics treatment neonatal infections and improving the quality of medical care for this category of newborn. The aim. Determination of the value of microbiological triggers in the blood in various clinical options for EONS in preterm infants. Materials and methods. Clinical and microbiological data on 50 prematurely born newborns with EONS were selected. The analysis of the frequency of detected bacteremia, the distribution of pathogenic microorganisms and the clinical characteristics of neonatal sepsis. Results. In the study, sources of infection were detected in 94 % of cases. Positive blood cultures were obtained in 17 (34 %) newborns with EONS. 61.5 % of all cases of bacteremia were caused by coagulase-negative staphylococcus (CoNS). Gram-negative pathogens were detected in 23.5 % of positive blood cultures, representatives of this group were Escherichia coli and Klebsiella pneumonia. The overall mortality rate from EONS was 30 %. Conclusions. The incidence of sepsis confirmed by a positive blood culture was 34 %. The most common cause of EONS is CoNS, low incidence of group B Streptococcus sepsis has been established. The most frequent septicopymic sources of infection were the lungs, which is expressed in the high incidence (94 %) of X-ray pneumonia in the structure of the EONS.

Prevalence of Neonatal Sepsis in Ethiopia: A Systematic Review and Meta-Analysis

Introduction

Neonatal sepsis is a systemic infection occurring in infants during the first 4 weeks of life and is a major cause of mortality and morbidities of newborns due to their age-related weak and immature immune systems. In Ethiopia, despite many studies being conducted on neonatal sepsis, the reported findings are inconsistent. The aim of this study is to determine the prevalence of neonatal sepsis to enhance the utility and interpretation of the evidence.

Methods

An extensive systematic review and meta-analysis were performed to extract studies on the prevalence of neonatal sepsis in Ethiopia. The PubMed, Cochrane Library, ScienceDirect, Web of Science, and Google Scholar were systematically searched. Two independent authors selected and extracted the data from each included article. The heterogeneity of included studies was assessed using the Higgins I ² test, and a random-effects model was performed in Stata/se Version 14.

Results

Eighteen studies with a sample size of 10,495 study subjects were included with a reported range of neonatal sepsis from 17% to 78%. The pooled prevalence of neonatal sepsis was 45% (95% CI: 35, 55; I ² = 99.3%, p < 0.01). Early onset neonatal sepsis was found to have a prevalence of 75.4% (95% CI: 68.3, 82.6). Subgroup analysis in the study area (i.e., by region) was calculated revealing the highest neonatal sepsis in Amhara region at 64.4% (95% CI: 44.9, 84.0) and the lowest in Southern Nations, Nationality, and People at 28% (95% CI: 16, 40).

Conclusion

In this review, the prevalence of neonatal sepsis in Ethiopia was found to be high, especially in terms of early onset neonatal sepsis. As a result of the findings, it is important to consider the early and optimal points for interventions to better manage the prevalence and outcomes of neonatal sepsis. Further research is needed to investigate the neonatal sepsis status at different regions and associated factors for neonatal sepsis not yet studied.

Prevalence and Associated Risk Factors of Sepsis among Neonates Admitted into Neonatal Intensive Care Units of Public Hospitals in Dhaka

OBJECTIVE

To determine the prevalence and associated risk factors of sepsis among neonates admitted into neonatal intensive care units (NICU) of public hospitals in Dhaka.

METHODS

This was a cross-sectional study conducted among 173 neonates admitted into the NICUs of Dhaka Medical College Hospital (DMCH) and Dhaka Shishu (Children) Hospital from March 1, 2016 to September 30, 2016 at Dhaka, Bangladesh. On the basis of the presence of clinical signs and symptoms of sepsis, neonates were admitted into the NICUs. The weight of the baby was measured and blood culture, complete blood count (CBC), C-reactive protein (CRP) and urine R/M/E were done at the time of admission. The neonates, who had positive blood culture reports, were confirmed as having sepsis. After receiving informed written consent, maternal data were collected from the mother of the neonate and neonatal data were collected from NICUs.

RESULTS

The prevalence of sepsis among the neonates admitted into NICU of the concerned public hospitals in Dhaka was 69.35%. In the multiple logistic regression model, perinatal asphyxia (adjusted odds ratio (aOR) = 3.37, 95% confidence interval (CI) = 1.27-8.90), presence of infection at umbilical cord (aOR = 3.32, 95% CI = 1.40-7.85), history of bottle feeding of the neonates (aOR = 3.02, 95% CI = 1.11-8.25) and pre-existing maternal infection (aOR = 4.44, 95% CI = 1.92-10.26) were significantly (p-value < 0.05) associated with neonatal sepsis. The odds of developing sepsis among the neonates with ≤ 2.5 kg weight at admission was more than three times higher (aOR 3.82, 95% CI = 1.59-9.19) than neonates with admission weight > 2.5 kg.

CONCLUSION

Like other South Asian countries, the prevalence of neonatal sepsis is alarming in Bangladesh. Further research should be conducted to measure the burden of infections in the entire neonatal period and observe the effects of biological risk factors on the early and late-onset neonatal sepsis.

Prevalence and Factors Associated with Neonatal Sepsis in a Tertiary Hospital, North West Nigeria

CONTEXT

Neonatal sepsis is an important cause of morbidity and mortality of newborns, especially in developing countries.

AIMS

Our study determined the prevalence of neonatal sepsis and its predisposing factors among neonates admitted in Ahmadu Bello University Teaching Hospital (ABUTH).

SETTINGS AND DESIGN

This was a cross-sectional descriptive study conducted in ABUTH.

SUBJECTS AND METHODS

The data were abstracted from the case notes of neonates admitted from May 2017 to May 2018. A pretested pro forma was used to abstract the data.

STATISTICAL ANALYSIS USED

Odds ratios and multivariate logistic regression were used to determine the factors associated with neonatal sepsis among the study population.

RESULTS

The prevalence of neonatal sepsis was 37.6%. Escherichia coli was the most commonly isolated organism. Neonates 0-7 days of age were 2.8 times less likely to develop neonatal sepsis than older neonates. Babies born with an Apgar score of <6 within the 1st min were 2.4 times more likely to develop neonatal sepsis than those whose Apgar score was higher. Neonates of mothers who had urinary tract infection during pregnancy were 2.3 times more likely to have had sepsis and those whose mothers had premature rupture of membranes were 4.6 times more likely.

CONCLUSIONS

The prevalence of neonatal sepsis was high among the neonates studied. Neonatal and maternal factors were associated with sepsis in the neonates. These findings provide guidelines for the selection of empirical antimicrobial agents in the study site and suggest that a continued periodic evaluation is needed to anticipate the development of neonatal sepsis among neonates admitted.

[Predictive factors for poor prognosis of neonates with early-onset sepsis]

OBJECTIVE

To study the predictive factors for poor prognosis of neonates with early-onset sepsis (EOS).

METHODS

The clinical data of 371 neonates with EOS were collected. According to prognosis, they were divided into a good prognosis group with 264 neonates and a poor prognosis group with 107 neonates. The two groups were compared in terms of perinatal conditions, clinical manifestations, laboratory markers, comorbidities, and treatment process. Multivariate logistic regression analysis was used to investigate the predictive factors for poor prognosis of EOS.

RESULTS

The poor prognosis group had significantly lower birth weight and gestational age than the good prognosis group (P<0.05). Compared with the good prognosis group, the poor prognosis group had significantly higher proportions of preterm neonates, low birth weight neonates, very low birth weight neonates and twins (P<0.05), as well as a significantly higher proportion of mothers who used hormone or antibiotics before delivery (P<0.05). Compared with the good prognosis group, the poor prognosis group had significantly higher incidence rates of poor response and respiratory hypofunction (P<0.05) and a significantly lower incidence rate of jaundice (P<0.05). Compared with the good prognosis group, the poor prognosis group had significantly higher incidence rates of white blood cell count <5×109/L, platelet count <100×109/L, anemia, coagulation disorder, renal dysfunction, liver impairment, hypoproteinemia, and hypoglycemia (P<0.05). The poor prognosis group had significantly higher incidence rates of neonatal respiratory distress syndrome, pulmonary hemorrhage, necrotizing enterocolitis, intraventricular hemorrhage, brain injury, pulmonary hypertension, and shock than the good prognosis group (P<0.05). Compared with the good prognosis group, the poor prognosis group had significantly longer length of hospital stay and course of treatment with antibiotics (P<0.05) and a significantly higher proportion of neonates receiving mechanical ventilation or vasoactive agents (P<0.05). The multivariate logistic regression analysis showed that very low birth weight (OR=41.734), necrotizing enterocolitis (OR=12.669), brain injury (OR=8.372), shock (OR=5.889), mechanical ventilation (OR=5.456), and liver impairment (OR=4.075) were independent predictive factors for poor prognosis of neonates with EOS (P<0.05).

CONCLUSIONS

Very low birth weight, mechanical ventilation, necrotizing enterocolitis, brain injury, shock, and liver impairment have a certain value in predicting the poor prognosis of neonates with EOS.

Very low birth weight, mechanical ventilation, necrotizing enterocolitis, brain injury, shock, and liver impairment have a certain value in predicting the poor prognosis of neonates with EOS.

Antibiotic regimens for neonatal sepsis - a protocol for a systematic review with meta-analysis

BACKGROUND

Sepsis is a major cause of morbidity and mortality among neonates and infants. Antibiotics are a central part of the first line treatment for sepsis in neonatal intensive care units worldwide. However, the evidence on the clinical effects of the commonly used antibiotic regimens for sepsis in neonates remains scarce. This systematic review aims to assess the efficacy and harms of antibiotic regimens for neonatal sepsis.

METHODS

Electronic searches will be conducted in MEDLINE, Embase, The Cochrane Library, CINAHL, ZETOC and clinical trial registries (clinicaltrials.gov and ISRCTN). We will include randomised controlled trials of different antibiotic regimens for sepsis of neonates and infants. Eligible interventions will be any antibiotic regimen. Two reviewers will independently screen, select, and extract data. The methodological quality of individual studies will be appraised following Cochrane methodology. Primary outcomes will be 'all-cause mortality' and 'serious adverse events'. Secondary outcomes will be 'need for respiratory support', 'need for circulatory support', 'neurodevelopmental impairment', ototoxicity, nephrotoxicity and necrotizing enterocolitis. We plan to perform a meta-analysis with trial sequential analysis.

DISCUSSION

This is the study protocol for a systematic review on the effects of different antibiotic regimens for neonatal sepsis. The results of this systematic review intent to adequately inform stakeholders or health care professionals in the field of neonatal sepsis, and to aid appropriate development of treatment guidelines.

Neonate Bloodstream Infections in Organization for Economic Cooperation and Development Countries: An Update on Epidemiology and Prevention

The term neonatal sepsis is used to describe a generalized bloodstream infection of bacterial, viral, or fungal origin which is associated with hemodynamic changes and other clinical symptoms and signs, however, there is no unified definition. There are no basic criteria regarding differentiation of early-onset sepsis (EOS) versus late-onset sepsis (LOS). Stratification used in studies on neonatal sepsis also rarely includes the general condition of the newborn according to unambiguous assessment at birth, which hampers the establishment of a clear, uniform epidemiological description of neonatal sepsis. We aim to review the published data about the epidemiology and microbiology of sepsis in Organization for Economic Cooperation and Development (OECD) countries. Data was also collected on sepsis prevention programs that can be implemented in neonatal units. The outcomes of interest were incidence or incidence density of EOS and LOS, microbiology of EOS and LOS, and data on the methodology of the research, in particular the criteria for inclusion and exclusion of newborns from the study. Pubmed, EMBASE, LILACS Embase, Scopus, and Google Scholar were used. For the preselection step, inclusion criteria included: "bloodstream infection" or "neonatal sepsis" (MesH), "very low birth weight", and "country" full-text studies, human, and English language. Exclusion criteria included: studies published in languages other than English and studies available only as an abstracts. For proper selection, inclusion criteria included: information about epidemiology or microbiology bloodstream infection (BSI), study population and case definitions, exclusion criteria, narrative reviews, commentaries, case studies, pilot studies, study protocols, pediatric studies, and only clinical data (without microbiology or epidemiology) or studies with only one etiological factor analysis. The data review indicated the lack of an unequivocal, unified definition and no unambiguous basic criteria with regard to differentiation of EOS versus LOS. Among infants <1500 g, studies reported an EOS rate from 7% to 2%. For studies using other definitions (mostly all inborn babies), the rate of EOS ranged from 1% to 3%. The LOS incidences were much more varied among countries; the highest rates were in the multicenter studies focused on very low birth weight (VLBW) infants. The main pathogens in EOS are GBS and Gram-negative bacteria in LOS. Our review data shows that LOS microbiology is very diverse and that Gram-positive cocci, especially staphylococci, predominate versus Gram-negative rods. Unfortunately, the lack of uniform, international prevention programs results in high newborn morbidity and insufficient postnatal prevention of late-onset infections.

The role of the season at admission in neonatal sepsis: a retrospective chart review of a 1-year data at University of Gondar comprehensive specialized hospital

Objective

Neonatal sepsis is a global public health concern in general and causes a massive burden in developing countries particularly in sub-Saharan Africa. Though it is mostly preventable, neonatal sepsis remained the leading cause of mortality in developing countries. This study was conducted to determine the current proportion and identify factors associated with neonatal sepsis to suggest directions.

Results

In this study 504 randomly selected neonatal charts were reviewed. The proportion of overall neonatal sepsis was 63.69% (95% CI 59.38, 67.79), where early-onset sepsis was 59.33% (95% CI 54.96, 63.55) and late-onset sepsis was 4.17% (95% CI 2.73, 6.31). Maternal intra-partum fever, season of birth and admission, vaginal mode of delivery and preterm gestational age at birth increased the likelihood of overall and early-onset neonatal sepsis. In conclusion of this study, neonatal sepsis remaining the leading cause of morbidity among younger infants. Intra-partum conditions were major contributors to neonatal sepsis. Thus, providing emphasis on associated factors in particular and universal safe obstetric care in general is recommended.

Unfinished agenda of the neonates in developing countries: magnitude of neonatal sepsis: systematic review and meta-analysis

Purpose

Neonatal sepsis is the major cause of mortality and morbidity globally, particularly in developing countries. Despite studies revealed the extent of neonatal sepsis in developing countries, the findings were inconclusive. Therefore, the main aim of this study was to determine the pooled prevalence of neonatal sepsis in developing countries.

Methods

We used a systematic review and Meta-analysis study method. The reviewed studies were accessed through an electronic web-based search strategy from the electronic database (PUBMED), advanced google scholar, different journal sites. The data extraction was done by two researchers using a data extraction table and the disparity between data extractors was resolved by the third researcher. The analysis was done using STATA version 11. The I2 test was used to assess heterogeneity across studies. The Funnel plot, Begg's test, and Egger's test were used to check for publication bias. The random-effect model was used to determine the pooled effect size. All studies related to neonatal sepsis which fulfill the inclusion criteria were considered into this study. The quality of each study was checked using the Newcastle-Ottawa Scale and studies graded low score were excluded from the study.

Results

At the end, 36 articles fit with our study objectives. Studies conducted in Ethiopia were significant the source of heterogeneity of the study with a coefficient = 90, P-value = 0.025. The overall pooled prevalence of the study was 29.92%. The limitations of this study would be the authors were only used articles reported in the English language, and publication bias.

Conclusion

The pooled prevalence of neonatal sepsis was found to be high which accounted for a third of the neonates. Despite countries have established possible prevention and treatment mechanisms, neonatal sepsis is the major public health problem in lower and middle-income countries till now.

Multiparameter flow cytometry analysis of leukocyte markers for diagnosis in preterm neonatal sepsis

PURPOSE

Neonatal sepsis is an important public health concern worldwide due to its immediate lethality and long-term morbidity rates, Clinical evaluation and laboratory analyses are indispensable for diagnosis of neonatal sepsis. However, assessing multiple biomarkers in neonates is difficult due to limited blood availability. The aim is to investigate if the neonatal sepsis in preterm could be identified by multiparameter analysis with flow cytometry.

MATERIALS AND METHODS

The expression of activation-related molecules was evaluated by flow cytometry in newborn with or without risk factors for sepsis.

RESULTS

Our analysis revealed that several markers could be useful for sepsis diagnosis, such as CD45RA, CD45RO, or CD71 on T cells; HLA-DR on NKT or classic monocytes, and TREM-1 on non-classic monocytes or neutrophils. However, ROC analysis shows that the expression of CD45RO on T lymphocytes is the only useful biomarker for diagnosis of neonatal late-onset sepsis. Also, decision tree analyses showed that CD45RO plus CD27 could help differentiate the preterm septic neonates from those with risk factors.

CONCLUSIONS

Our study shows a complementary and practical strategy for biomarker assessment in neonatal sepsis.

Proportion of neonatal sepsis and determinant factors among neonates admitted in University of Gondar comprehensive specialized hospital neonatal Intensive care unit Northwest Ethiopia 2017

OBJECTIVE

Neonatal sepsis is one of the most common causes of neonatal hospitalization in developing countries. It is also a major cause of mortality in the world affecting both developed and developing countries. Diagnosis and management of sepsis are a great challenge facing neonatologists in neonatal intensive care units due to nonspecific signs and symptoms. This study, therefore, was aimed to determine proportion and risk factors of neonatal sepsis at university of Gondar comprehensive specialized hospital, North West Ethiopia.

RESULT

The proportion of neonatal sepsis was 11.7%. Factors significantly associated with neonatal sepsis were: Neonatal related factors were: Premature rupture of membrane (AOR = 2.74; 95% Cl (1.39, 5.38), congenital anomaly (AOR = 3.14; 95% CI (1.09, 10.28), and low Apgar score (AOR = 2.69; 95% Cl (1.37, 5.26). Maternal factors were: foul-smelling vaginal discharge (AOR = 2.75; 95% Cl (1.40, 5.38), and Intrapartum fever (AOR = 3.35; 95% Cl (1.7, 6.62). In this finding proportion of Neonatal sepsis was low as compared to previous studies. Measures targeting the prevention of premature rupture of membranes and low Apgar score need to be taken, like strengthening maternal birth preparedness and complication readiness plans. Also, identification of congenital anomalies earlier in pregnancy and taking measures to avoid birth injury may decrease neonatal sepsis.

Determinants and Outcome of Community-Acquired Late-Onset Neonatal Sepsis in Rural Bangladesh

Background. This study examined the sociodemographic as well as other determinants and outcome of community-acquired late-onset neonatal sepsis (LONS) in rural Bangladesh at Matlab. Methods. In this retrospective chart review, we used an unmatched case-control design (1:2 ratio) to evaluate the factors associated with LONS and their outcomes among babies admitted to the neonatal ward of Matlab Hospital of icddr,b, from January 2012 to December 2014. Neonates presenting with any of the clinical signs of serious bacterial infection during 3 to 28 days of life constituted the cases (LONS), and those without LONS constituted the controls. All the data were retrieved from the electronic databases of Matlab Hospital and Matlab Health and Demographic Surveillance System. Results. Among 1482 admitted neonates, 202 were cases and 404 were randomly selected controls. In babies with LONS, case fatality rate (1% vs 0%, P = .037), duration of inpatient stay (4 days vs 2 days, P < .001), and referral to higher center (9% vs 5%, P = .020) were higher. In an adjusted model, undernutrition (weight for length Z score < −2; odds ratio [OR] = 1.8, 95% confidence interval [CI] = 1.2-2.94), admission in winter season (OR = 1.62, 95% CI = 1.09-2.41), mother’s schooling <10 years (OR = 1.76, 95% CI = 1.09-2.85), primiparity (OR = 1.55, 95% CI = 1.05-2.29), home delivery (OR = 1.87, 95% CI = 1.07-3.26), and household food insecurity (OR = 2.78, 95% CI = 1.31-5.88) were found to be independently associated with LONS. Conclusion. LONS posed considerable socioeconomic burden to the rural community. Further studies are required to consolidate our findings.

Etiology of early onset neonatal sepsis in neonatal intensive care unit - Mansoura, Egypt

INTRODUCTION

This study was conducted to find out the bacterial causes of early onset neonatal sepsis and their susceptibility pattern for different classes of antibiotics in neonates admitted to neonatal intensive care unit (NICU) of Mansoura-Egypt.

METHODS

A descriptive cross-sectional study was conducted. All admitted newborns to our study were infants at <72 hours of age with clinical features of sepsis or product of an in-house delivery at Mansoura University Hospital with risk factors for neonatal sepsis. Identification of Gram-negative isolates was confirmed by API 20E kits (bioMerieux). Antibiotic susceptibility was performed by Kirby-Bauer disc diffusion method. Bacteria resistant to ≥3 antimicrobial classes were counted as multidrug resistant.

RESULTS

One hundred eighty eight babies were admitted to our study. Positive blood culture was reported in 34.6% of newborn infants with prevalence of 4.02/1,000 live births. The most common isolated bacteria in early onset neonatal sepsis were coagulase negative staphylococci followed by Klebsiella pneumoniae and Serratia marcescens. The Gram-positive bacteria showed high resistance to ampicillin 93.9% while all the isolates were susceptible to vancomycin. The isolated Gram-negative bacteria were highly resistant to ampicillin [96.9%], amoxicillin-clavulanic acid [90.6%], cefotaxime [84.4%] and ceftazidime [84.4%]. Best sensitivity among all isolates was observed to imipenem. Multidrug resistance was observed among 45.5% of the Gram-positive and 68.8% of Gram-negative isolates.

CONCLUSION

Appropriate identification of the source of infection and initiation of an effective management can reduce both mortality and morbidity associated with neonatal sepsis. The challenge is to initiate immediate empirical antibiotic therapy according to a strictly implemented updated antibiotic policy based on an individualized community established antimicrobial sensitivity pattern of microorganisms causing early onset neonatal sepsis.

Risk Factors Associated with Neonatal Sepsis: A Case Study at a Specialist Hospital in Ghana

Worldwide, neonatal sepsis accounts for an estimated 26% of under-five deaths, with sub-Saharan Africa having the highest mortality rates. Though worldwide neonatal deaths have decreased by over 3.6 million per year since 2000, neonatal sepsis remains a notable hindrance to the progress in the decline of cause-specific mortality rates especially in sub-Saharan Africa. This study aimed at examining the risk factors of neonatal sepsis at the Trauma and Specialist Hospital, Winneba. The study was an unmatched case control retrospective study. Cases were neonates who had sepsis with their index mothers and controls were neonates who did not have sepsis with their index mothers. Neonatal and maternal medical records were retrieved from January to December 2017. Data abstraction lasted for one month and 2650 folders for the neonates and their index mothers were retrieved. Nine hundred (900) neonatal folders were considered valid for the study and likewise for the maternal folders. One hundred and three (103) folders were considered cases while 797 were considered as controls. Data were entered using the Statistical Package for Social Sciences Version 22. Logistic regression was used to determine the risk of neonatal sepsis. Maternal factors that predicted the occurrence of sepsis among neonates were parity (p<0.027), mode of delivery (p<0.001), bleeding disorder (p<0.001), and PROM (p<0.001). Neonatal risk factors which predicted the occurrence of sepsis were APGAR score in the first and fifth minute (p<0.001), resuscitation at birth (p<0.004), duration of stay in the facility (p<0.001), and neonatal age on admission (p<0.001). The study found both maternal and neonatal factors to have a strong association with the risk of developing neonatal sepsis. Encouraging maternal antenatal care utilization would help identify the risk factors during prenatal and postnatal care and appropriate interventions implemented to reduce the likelihood of the neonate developing sepsis.

Risk Factors for Neonatal Sepsis: A Retrospective Case-Control Study among Neonates Who Were Delivered by Caesarean Section at the Trauma and Specialist Hospital, Winneba, Ghana

The third Sustainable Development Goal (SDG) for child health, which targets ending preventable deaths of neonates and children under five years of age by 2030, may not be met without substantial reduction of neonatal sepsis-specific mortality in developing countries. This study aimed at assessing the prevalence and risk factors for neonatal sepsis among neonates who were delivered via caesarean section. A retrospective case-control study was conducted among neonates who were delivered via caesarean section at the Trauma and Specialist Hospital, Winneba, Ghana. Data collection lasted for 4 weeks. The extracted data were double-entered using Epidata software version 3.1 to address discrepancies of data entry. Descriptive statistics such as frequencies and percentages of neonatal characteristics were generated from the data. Both univariate and multivariate logistic regression were used to determine associations between neonatal sepsis and neonatal characteristics with odds ratios, 95% confidence intervals, and p values calculated using variables that showed significant association (p<0.05) in the chi-square analysis for the multivariate logistic regression. A total of 383 neonates were recruited; 67 (17.5%) had sepsis (cases). The neonatal risk factors associated with sepsis were birth weight (χ2=6.64, p=0.036), neonatal age (χ2=38.31, p<0.001), meconium passed (χ2=12.95, p<0.001), reason for CS (χ2=24.27, p<0.001), and the duration of stay on admission (χ2=36.69, p<0.001). Neonatal sepsis poses a serious threat to the survival of the newborn as the current study uncovered 6.0% deaths among sepsis cases. The findings of this study highlight the need for routine assessment of neonates in order to identify risk factors for neonatal sepsis and to curb the disease burden on neonatal mortality.
