The document discusses common bacterial infections in children. The most common bacterial infections in babies are skin, ear, and throat infections, while the most common viral infections are respiratory infections such as RSV. Over 44% of child deaths under age 5 occur during the neonatal period, with approximately 2.6 million neonatal deaths worldwide in 2015. Bacterial infections and sepsis are major causes of neonatal mortality. Prevention strategies discussed include immunization of mothers and children, breastfeeding, hygiene practices like chlorhexidine cord care, and education of health professionals in neonatal resuscitation. Prudent antibiotic use and stewardship programs are important to prevent antibiotic resistance.

children
The most common bacterial
infections in babies are skin, ear,

Neonatal infections/ sepsis
Child health AND maternal health!

8. Prevention
• Immunization maternal, childhood, general population
• Nutrition breast-feeding, weight, Kangaroo Mother Care
• Hygiene perinatal, use of chlorhexidine for cord care
• Education health professionals (neonatal resuscitation),
leaflets, trainings, workshops

9. Prevention
• Immunization maternal, childhood, general population
“immunologic immaturity”: ineffective clearing of intracellular
pathogens, only moderate antibody generation against bacterial
polysaccharides, …
Palmeira P et al., Clin Dev Immunol 2012
Neonates/ young babies:
1. Unprotected (insufficient maternal protection, e.g. pertussis)
2. More robust protection after several months of life (ca. 6 months)
3. Lack of vaccinations licensed for this young age group (e.g. influenza)

10. Increase in steroid hormones
Immune system: Shift TH1 to TH2
(„antiinflammatory“)
--I cytotox. T-lymphocytes
 B-lymphocyte stimulation
Increase of diaplacental
IgG-transfer
Omer SB, NEJM 2017

11. Prevention
• Immunization counselling of women, who wish to
have children! (check immunization status)

Maternal Vaccination

13. Tetanus
• Propagated by WHO since 1974 to reduce the risk of
neonatal tetanus
• Vaccination against tetanus during pregnancy is safe!
“…Although this approach has decreased neonatal tetanus by 96%
compared to the late 1980s, the WHO estimated that 34,000 new-borns
still died from the disease in 2015 …”

“… Transplacental antibody transfer can be significantly reduced by a
short interval between the last dose of TTCV before delivery (<14 days),
prematurity, and conditions such as maternal HIV infection,
hypergammaglobulinemia in the context of malaria and chronic placental
malaria infection …”

15. • California, US-cohort of 74.504 mother-child pairs
• Risk of symptomatic pertussis infection during the first 2 months of life
• Prenatal vs. postnatal vaccination
 Vaccination during 27th–36th week of pregnancy improved
propability of childhood protection against pertussis by 85% as
compared to vaccination during 14 days postpartum!
Winter K et al., Clin Infect Dis 2017

16. Mothers vaccinated:
49 infants diseased  43% hospitalization rate
3 days average duration of hospitalization
no deaths
Mothers non-vaccinated:
371 infants diseased  73% hospitalization rate
6 days average duration of hospitalization
6 deaths

17. Prevention
• Immunization maternal, childhood, general population
• Nutrition breast-feeding, Kangaroo Mother Care
• Hygiene perinatal, use of chlorhexidine for cord care
• Education health professionals (neonatal resuscitation),
leaflets, trainings, workshops

18. Raihana S et al., PLoS Med 2019; 16(8): e1002904
• Study from Bangladesh
• Neonatal sepsis: 24% of neonatal deaths
• Only 50% of newborns in Bangladesh initiated breastfeeding
within 1 hour of birth
• Initiation of breastfeeding and severe illness
• the earlier the initiation of breastfeeding, the lower the risk
of having severe illnesses in the early newborn stage

19. Prevention
• Immunization maternal, childhood, general population
• Nutrition breast-feeding, Kangaroo Mother Care
• Hygiene perinatal, use of chlorhexidine for cord care
• Education health professionals (neonatal resuscitation),
leaflets, trainings, workshops

20. Awareness
• Public awareness neonatal care
• Easy access to medical care midwifes, community nurses
• Education red flags (outpatient/ inpatient)
Treatment
• Know your microbes (and your antimicrobial resistance)
• Empirical, promt treatment (right drug, dose, duration)
• Antibiotic Stewardship

21. Increased antibiotic consumption is associated with increasing
numbers of resistance against antibiotics

Up to 50% of all prescribed antibiotics in hospitals are unneccessary!

responsible for the death of the man who finally succumbs to
infection with the penicillin-resistant organism. I hope this evil
can be averted.“

Missuse of Antibiotics Increases Antimicrobial Resistance

24. „rational use of antibiotics“
„optimal choice, dose and duration of antimicrobial therapy or
prophylaxis, with minimal toxicity for the patient as well as with the
lowest potential for developing resistance“

What are Antimicrobial Stewardship Programs?

25. 1. 4 D‘s Drug, Dose, De-escalation, Duration
Joseph and Rodvold, Expert Opin Pharmacother 2008
2. Stop overuse (wrong indication)
wrong use (missing adaptation)
missuse („favoured drug“)
3. Minimize development of resistance
antibiotics risk for colonization or infection with
resistant organisms
Dellit et al., Clin Infect Dis 2007
What are Antimicrobial Stewardship Programs?

26. Neonatal infections/ sepsis
• Antibiotic Stewardship
Diagnostics:
- blood culture(s) (1ml!) (low grade bacteremia)
- supportive role of biomarkers (CRP, IL-6, IL-8, PCT)
( good negative predictive value; can help to
reduce antobiotic consumption)

27. • Neonates with suspected bacterial infection:
Test: combination of CRP and IL-8 (vs. CRP and I/T neutrophil
ratio)
Outcome: Reduction of antibiotics by 73%!
• Neonates with suspected early onset sepsis (EOS):
Test: IL-8 and CRP (vs. CRP alone)
(IL-8 > 70 pg/mL and/ or CRP > 10 mg/L)
Outcome: 50% reduction (vs. 36%), without an increase in
missed infections
Franz et al., 2001
Franz et al., 2004

28. Neonatal infections/ sepsis
• Antibiotic Stewardship
Therapy:
- dosage and monitoring of antimicrobial levels
- e.g. gentamicin: higher doses at longer intervalls
- detect toxicity „trough levels“ and access potency
„peak levels“ (e.g. vancomycin 10-20 mg/l)
