Defining common infections in children and neonates

Determinants of late-onset neonatal sepsis among neonates admitted to the neonatal intensive care unit of Arba-Minch general hospital, southern Ethiopia

INTRODUCTION

Neonatal sepsis can be either early (<7 Days) or late-onset ≥7days) neonatal sepsis depending on the day of the occurrence. Despite the decrement in early onset neonatal sepsis, there is still an increment in late-onset neonatal sepsis. Ethiopian demography and health survey report showed an increment in neonatal mortality in 2019/20.

OBJECTIVE

The objective of this study was to assess the determinants of late-onset neonatal sepsis among neonates admitted to the neonatal intensive care unit at Arba-Minch general hospital, southern Ethiopia.

METHODS

An institution based study was conducted from March 1, 2021, to June 30, 2021 in Arba-Minch general hospital. Cases were neonates diagnosed with late-onset neonatal sepsis with their index mother chart and controls were neonates admitted with other diagnoses at the same period. Cases and controls were selected consecutively. Data extraction tool and interview which was developed by reviewing different kinds of literature was used to collect data. Data were entered by using Epi data version 3.1software and transformed to Statistical Package for Social Sciences version 25 software for analysis. The binary logistic regression model was used to assess determinants and variables with a p-value <0.2 were transformed to multivariable logistic regression then, a p-value < 0.05 with 95% confidence interval were used to declare significant association with the outcome variable.

RESULT

A total of 180 subjects (60 cases and 120 controls) were included in this study. The mean age of neonates was 12.1 days with standard deviations of 4.3. Multivariable logistic regression analysis showed that; history of either sexually transmitted disease /urinary tract infection [AOR = 9.4; 95%CI(3.1-28.5)], being preterm (gestational age of <37 weeks) [AOR = 4.9; 95%CI (1.7-13.7)], use of endotracheal intubation/mechanical intubation [AOR = 8.3; 95%CI (1.8-26.4)]and either mixed types of infant feeding option or formula feeding before admission [AOR = 12.7; 95%CI(3.7-42.8)]were significantly associated with late-onset neonatal sepsis.

CONCLUSION AND RECOMMENDATIONS

This study revealed that antenatal, intrapartum and postpartum factors have shown an association with late-onset neonatal sepsis. It is recommended to strengthen counseling and advice to mothers with specific risk factors of late-onset neonatal sepsis.

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.

Hand hygiene for the prevention of infections in neonates

BACKGROUND

Annually, infections contribute to approximately 25% of the 2.8 million neonatal deaths worldwide. Over 95% of sepsis-related neonatal deaths occur in low- and middle-income countries. Hand hygiene is an inexpensive and cost-effective method of preventing infection in neonates, making it an affordable and practicable intervention in low- and middle-income settings. Therefore, hand hygiene practices may hold strong prospects for reducing the occurrence of infection and infection-related neonatal death.

OBJECTIVES

To determine the effectiveness of different hand hygiene agents for preventing neonatal infection in community and health facility settings.

SEARCH METHODS

We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 5), in the Cochrane Library; MEDLINE via PubMed (1966 to 10 May 2019); Embase (1980 to 10 May 2019); and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 10 May 2019). We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-randomised trials. Searches were updated 1 June 2020.

SELECTION CRITERIA

We included RCTs, cross-over trials, and quasi-RCTs that included pregnant women, mothers, other caregivers, and healthcare workers who received interventions within the community or in health facility settings DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane and the GRADE approach to assess the certainty of evidence. Primary outcomes were incidence of (study author-defined) suspected infection within the first 28 days of life, bacteriologically confirmed infection within the first 28 days of life, all-cause mortality within the first seven days of life (early neonatal death), and all-cause mortality from the 8th to the 28th day of life (late neonatal death).

MAIN RESULTS

Our review included five studies: one RCT, one quasi-RCT, and three cross-over trials with a total of more than 5450 neonates (two studies included all neonates but did not report the actual number of neonates involved). Four studies involved 279 nurses working in neonatal intensive care units and all neonates on admission. The fifth study did not clearly state how many nurses were included in the study. Studies examined the effectiveness of different hand hygiene practices for the incidence of (study author-defined) suspected infection within the first 28 days of life. Two studies were rated as low risk for selection bias, another two were rated as high risk, and one study was rated as unclear risk. One study was rated as low risk for allocation bias, and four were rated as high risk. Only one of the five studies was rated as low risk for performance bias. 4% chlorhexidine gluconate (CHG) compared to plain liquid soap We are uncertain whether plain soap is better than 4% chlorhexidine gluconate (CHG) for nurses' skin based on very low-certainty evidence (mean difference (MD) -1.75, 95% confidence interval (CI) -3.31 to -0.19; 16 participants, 1 study; very low-certainty evidence). We identified no studies that reported on other outcomes for this comparison. 4% chlorhexidine gluconate compared to triclosan 1% One study compared 1% w/v triclosan with 4% chlorhexidine gluconate and suggests that 1% w/v triclosan may reduce the incidence of suspected infection (risk ratio (RR) 1.04, 95% CI 0.19 to 5.60; 1916 participants, 1 study; very low-certainty evidence). There may be fewer cases of infection in the 1% w/v triclosan group compared to the 4% chlorhexidine gluconate group (RR 6.01, 95% CI 3.56 to 10.14; 1916 participants, 1 study; very low-certainty evidence); however, we are uncertain of the available evidence. We identified no study that reported on all-cause mortality, duration of hospital stay, and adverse events for this comparison. 2% CHG compared to alcohol hand sanitiser (61% alcohol and emollients) We are uncertain whether 2% chlorhexidine gluconate reduces the risk of all infection in neonates compared to 61% alcohol hand sanitiser with regards to the incidence of all bacteriologically confirmed infection within the first 28 days of life (RR 2.19, 95% CI 1.79 to 2.69; 2932 participants, 1 study; very low-certainty evidence) in the 2% chlorhexidine gluconate group, but the evidence is very uncertain.   The adverse outcome was reported as mean visual scoring on the skin. There may be little to no difference between the effects of 2% CHG on nurses' skin compared to alcohol hand sanitiser based on very low-certainty evidence (MD 0.80, 95% CI 0.01 to 1.59; 118 participants, 1 study; very low-certainty evidence). We identified no study that reported on all-cause mortality and other outcomes for this comparison. None of the included studies assessed all-cause mortality within the first seven days of life nor duration of hospital stay.  AUTHORS' CONCLUSIONS: We are uncertain as to the superiority of one hand hygiene agent over another because this review included very few studies with very serious study limitations.

Risk factors and etiology of neonatal sepsis after hospital delivery: A case-control study in a tertiary care hospital of Rajshahi, Bangladesh

BACKGROUND

Sepsis is one of the major causes of neonatal death worldwide as well as in Bangladesh. The objective of the present study was to identify the risk factors and causative organisms of neonatal sepsis after delivery in a tertiary care hospital, Bangladesh.

METHODS

This was a case-control study conducted in the neonatal ward of Rajshahi Medical College Hospital (RMCH), a 1000-bed tertiary hospital situated in Rajshahi, Bangladesh. Neonates diagnosed as neonatal sepsis by clinical and laboratory parameters were included as cases in this study. Admitted neonates unsuspected or undiagnosed for sepsis were considered as controls. Maternal and neonatal information and their laboratory reports were collected and analyzed. Both bivariate and multiple logistic regression models were used to identify the risk factors of neonatal sepsis.

RESULTS

A total of 91 cases and 193 controls were included in the study. Maternal history of urinary tract infection (UTI) during the third trimester of pregnancy (aOR 2.75, 95% CI: 1.04-7.23, p <0.05), premature birth (aOR 2.77, 95% CI: 1.08-7.13, p <0.05) and APGAR score <7 at five minutes (aOR 2.58, 95% CI: 1.04-6.39, p <0.05) were associated with onset of neonatal sepsis in multiple logistic regression model. All these factors were also associated with developing early-onset neonatal sepsis, while maternal UTI and male sex of neonates were associated with developing late-onset neonatal sepsis. Escherichia coli (40.7%), Staphylococcus aureus (27.5%), and Klebsiella pneumoniae (18.7%) were the commonly isolated organisms causing neonatal sepsis. All these organisms were highly resistant to common antibiotics like amoxicillin, cephalosporins, aminoglycosides and quinolones. Carbapenemase group of drugs along with amikacin, nitrofurantoin and linezolid were the most sensitive drugs.

CONCLUSIONS

Strengthening the existing facility for antenatal screening for early diagnosis and treatment of maternal infection during pregnancy as well as identifying high-risk pregnancy for adequate perinatal management is necessary to prevent neonatal sepsis-related morbidity and mortality. Rational use of antibiotics according to local epidemiology and culture and sensitivity reports may minimize the increasing hazards of antibiotic resistance.

Bacteriological profile of neonatal sepsis and antibiotic susceptibility pattern of isolates admitted at Kanti Children's Hospital, Kathmandu, Nepal

Objective

Neonatal sepsis is a major cause of morbidity and mortality of newborns (< 1 month of age). Septicemia and drug resistance is a predominant issue for neonatal death in Nepal. This study is intended to find bacteriological profile of neonatal sepsis and antibiotic susceptibility pattern of the isolates from neonates at Kanti Children’s Hospital, Kathmandu, Nepal.

Results

Out of 350 suspected cases of neonatal sepsis, 59 (16.9%) cases showed positive blood culture. The prevalent of positive blood culture with different neonatal risk factors (sex, age, birth weight, gestational age, and delivery mode) showed highest positive bacterial growth in male (52.3%); 3 or above 3 days age (71.2%); low birth weight (62.7%); preterm gestational age (31.4%); and caesarean delivery mode (63.3%). Among positive cases, the bacteriological profile was found highest for Staphylococcus aureus (35.6%) followed by Klebsiella pneumoniae (15.3%). The most sensitive and resistive antibiotics among Gram-positive isolates were gentamicin (93%) and ampicillin (78%), respectively. Meropenem and imipenem showed highest 100% effective and cefotaxime was least (28%) sensitive among Gram-negative isolates. This concludes broad ranges of bacteria are associated with neonatal sepsis and revealed variation in antibiotic susceptibility pattern among bacterial isolates.

Risk Factors for Neonatal Sepsis in Public Hospitals of Mekelle City, North Ethiopia, 2015: Unmatched Case Control Study

OBJECTIVES

Neonatal sepsis is a leading cause of neonatal morbidity and mortality, particularly in the developing countries. Delays in the identification and treatment of neonatal sepsis are among the main contributors to the high mortality. The aim of this study was to determine the risk factors of neonatal sepsis in public hospitals of Mekelle City, Tigray Region, North Ethiopia, 2015.

METHODS

A hospital based case control study was done in public hospitals of Mekelle City, Tigray region. Cases were neonates who had sepsis with their index mothers and controls were neonates who hadn't had sepsis with their index mothers. Hematologic findings were used to diagnose sepsis once the neonates were being clinically suspected. Cases and controls were selected using the systematic sampling technique. Data were entered using Epi info version 7 and then analyzed using SPSS window 20. The binary logistic regression model was used to test the association between dependent and independent variables and multivariable logistic regression was used to identify the associated risk factors to neonatal sepsis.

FINDINGS

A total of 78 cases and 156 controls were included in this study. More than three quarters (76.8%) of cases had early onset sepsis. The multivariable logistic regression analysis showed that the possible risk factors of neonatal sepsis in this study were; history of maternal urinary tract infection or sexually transmitted infection [AOR = 5. 23; 95% CI (1.82, 15.04)], prolonged rupture of membrane [AOR = 7. 43; 95% CI (2.04, 27.1)], Place of delivery; health center delivery [AOR = 5. 7; 95% CI (1.71, 19.03)], intrapartum fever [AOR = 6. 1 95% CI (1.29, 28.31)], APGAR score <7 at 5th minute [AOR = 68. 9; 95% CI (3.63, 1308)] and not crying immediately at birth [AOR = 124. 0; 95% CI (6.5, 2379)].

CONCLUSION

Both maternal and neonatal factors had contributed to the risk of neonatal sepsis. Strengthening of the existing risk based prevention strategies as well as improvement of institutional delivery practices are crucial.

Is a lumbar puncture necessary when evaluating febrile infants (30 to 90 days of age) with an abnormal urinalysis?

OBJECTIVES

Guidelines for the management of febrile infants aged 30 to 90 days presenting to the emergency department (ED) suggest that a lumbar puncture (LP) should be performed routinely if a positive urinalysis is found during initial investigations. The aim of our study was to assess the necessity of routine LPs in infants aged 30 to 90 days presenting to the ED for a fever without source but are found to have a positive urine analysis.

METHODS

We retrospectively reviewed the records of all infants aged 30 to 90 days, presenting to the Montreal Children's Hospital ED from October 2001 to August 2005 who underwent an LP for bacterial culture, in addition to urinalysis and blood and urine cultures. Descriptive statistics and their corresponding confidence intervals were used.

RESULTS

Overall, 392 infants were identified using the microbiology laboratory database. Fifty-seven patients had an abnormal urinalysis. Of these, 1 infant (71 days old) had an Escherichia coli urinary tract infection, bacteremia, and meningitis. This patient, however, was not well on history, and the peripheral white blood cell count was low at 2.9 × 10⁹/L. Thus, the negative predictive value of an abnormal urinalysis for meningitis was 98.2%.

CONCLUSIONS

Routine LPs are not required in infants (30-90 days) presenting to the ED with a fever and a positive urinalysis if they are considered at low risk for serious bacterial infection based on clinical and laboratory criteria. However, we recommend that judicious clinical judgment be used; in doubt, an LP should be performed before empiric antibiotic therapy is begun.

Antibiotic use for presumed neonatally acquired infections far exceeds that for central line-associated blood stream infections: an exploratory critique

OBJECTIVE

To assess antibiotic use as a complementary neonatal intensive care unit (NICU) infection measure to the central line-associated blood stream infection (CLABSI) rate.

STUDY DESIGN

Patient days (PDs), line days, antibiotic (AB) use, CLABSI and other proven infections were analyzed in consecutive admissions to two NICUs over 3 and 6 months, respectively, from 1 January 2008 until discharge. An antibiotic course (AC) consisted of one or more uninterrupted antibiotic days (AD), classified as perinatal or neonatal, if started ≤3 d or ≥4 d post birth and as rule-out sepsis or presumed infection (PI) if treated ≤4 d or ≥5d, respectively. Events were expressed per 1000 PD and aggregated by conventional treatment categories and by clinical perception of infection certainty: possible, presumed or proven.

RESULT

The cohort included 754 patients, 18,345 PD, 6637 line days, 718 AC and 4553 AD. Of total antibiotic use, neonatal use constituted 39.2% of ACs, and 29.0% of ADs, When analyzed per 1000 PD, antibiotic use to treat PIs vs CLABSIs, was either 14 fold (CI 6.6-30) higher for ACs (5.40 vs 0.38/1000 PD, P<0.0001) or 8.8 fold (CI 7.1-11) higher for ADs (48.3 vs 5.5/1000 PD, P<0.0001).

CONCLUSION

CLABSI rates, present a lower limit of NICU-acquired infections, whereas antibiotic-use measures, about 10-fold higher, may estimate an upper limit of that burden. Antibiotic-use metrics should be evaluated further for their ability to broaden NICU infection assessment and to guide prevention and antibiotic stewardship efforts.

'Haptoglobin concentrations in preterm and term newborns'

OBJECTIVE

To measure systemic haptoglobin (HPT) concentrations from birth in preterm (PT) and T newborns. To compare HPT in newborns without hemolysis or infection with values in bacteremic newborns.

STUDY DESIGN

HPT was measured using enzyme-linked immunosorbent assay in 30 PT and 28 T newborns without hemolysis or infection at birth (cord blood), on days of life 2 to 4, and at 1 to 2 weeks of life. Concentrations were measured in eight additional newborns with bacteremia. Wilcoxon-Mann-Whitney test was used for comparisons.

RESULT

HPT concentrations were consistently measurable from birth in PT and T neonates. Values were significantly greater in 2- to 4-day-old PT and T newborns than in newborns at birth (P<0.01). Bacteremic newborns had higher HPT concentrations than newborns without infection (P=0.033).

CONCLUSION

HPT is detectable from birth in PT and T newborns. HPT concentrations increase in bacteremic newborns. HPT levels may have clinical utility in the evaluation of neonatal sepsis.

Pathophysiology and treatment of septic shock in neonates

Neonatal septic shock is a devastating condition associated with high morbidity and mortality. Definitions for the sepsis continuum and treatment algorithms specific for premature neonates are needed to improve studies of septic shock and assess benefit from clinical interventions. Unique features of the immature immune system and pathophysiologic responses to sepsis, particularly those of extremely preterm infants, necessitate that clinical trials consider them as a separate group. Keen clinical suspicion and knowledge of risk factors will help to identify those neonates at greatest risk for development of septic shock. Genomic and proteomic approaches, particularly those that use very small sample volumes, will increase our understanding of the pathophysiology and direct the development of novel agents for prevention and treatment of severe sepsis and shock in the neonate. Although at present antimicrobial therapy and supportive care remain the foundation of treatment, in the future immunomodulatory agents are likely to improve outcomes for this vulnerable population.
