1. Congenital and Neonatal Malaria in Unit of Reanimation and Neonatology of CHU Gabriel Toure Dicko-Traore F.¹, Sylla M.¹,, Dara A.², Dama S.², Traore K.¹, Togo P.¹, Traore S.¹, Sissoko Sibiry ², Poudiougo B.², Keita M.¹, Doumbo O.² And Djimde AA². 1-Service de Pédiatrie, CHU Gabriel Toure, Bamako, Mali 2-Malaria Research and Training Center, Bamako, Mali

2. Background • Cause of neonatal deaths is not known • Infection suspected • Pediatricians use their clinical judgment to treat

3. Introduction(1) • Malaria = first cause of mortality & morbidity in Mali (EDS IV) • Malaria = 50% of HGT Pediatrics admissions (Campbell et al., 2004) • Most pregnant women are exposed to repeated malaria infection

4. Introduction(2) • Most report of congenital malaria are case in non-endemic countries (Thompson, 1977; Laosombat, 1981) • Recent reports suggest that congenital malaria is not as rare among newborns in Sub-Saharan Africa (Ficher 1997;Akindele, 2003) • Whether malaria accounts for mortality or morbidity in neonates in Mali is not known.

5. Objective To determine the rate of congenital and acquired malaria in inpatient neonates at a tertiary paediatric hospital of Mali.

6. Methods (1) • Unit of Reanimation and Neonatology of Hopital Gabriel Toure • October 2006 and April 2008 • Cross-sectional study in infants aged 0-28 days and their mothers • Inclusion criteria • AG >= 37 SA • admitted for inpatient care to the Unit of Reanimation and Neonatology • Parental informed consent granted

7. Methods (2) • Procedures • informed parental consent • Venous blood collected for malaria diagnosis by OptiMal-IT test, microscopy and PCR. • If infant is enrolled, mother is approached for enrollment

8. Rapid Diagnostic test : 15mn

9. 1 2 3 4 PCR Diagnosis: 3H 120bp

10. Methods (3)

11. Descriptive results • 146 mothers • 300 infants

12. Mother’s social status Mean age : 25.26 years ±6.93

13. Prevalence of parasitemia in mothers P. Falciparum : 7/9 P. ovale : 2/9

14. Chemoprophylaxis

15. Characteristics of infants

16. Prevalence of parasitemia in infants (1)

17. Prevalence of parasitemia in infants (2) • Infants are believed to be protected from malaria (Bruce-Chwatt LJ,1952; Snow RW, 1998) • Prevalence up to 33% in endemic areas (Ankindele,1993) • Clinically atypical malaria occurring in infants and pre-term babies have been reported (Hewson M, 2003)

18. Clinical diagnosis

19. Conclusion • Despite several years of Sulfadoxine-pyrimethamin IPTp policy, 40% women still used chloroquine • Data suggest that malaria is not a significant contributor to neonatal morbidity and mortality in this setting

20. Futur studies • Neonatal malaria in preterms • Explore prevalence in older infants 1 - 6 months • Investigate mechanisms of infant protection from malaria
