15 REFERENCE M. TEMMERMAN, F. MOHAMED ALI, L.FRANSEN Syphilis prevention in pregnancy : an opportunity to improve reproductive and child health in Kenya. Health planning and policy 8 (2) : Follow-up:submitted for publication

16 Intervention IMPUTS: Reogarnisation: - No referral for bleeding or treatment - Immediate testing at the place of visit - Quality control and supervision Inclusion of counselling and partner notification. Same inputs as earlier : budget, diagnostics, drugs

17 BASELINE/ INTERVENTION Patients In Sample Blood Taken Screened For Syphilis Mean Seropositivity Treatment Level Partners Notified Partners Treated Baseline %87%3.80%1/11(+)00 After Intervention %99.98%6.80%83.10%85.10%46.80%

18 COSTS (DIRECT and INDIRECT) 2.50 US$ per patient visiting 11 Woman out of 291 tested (540 visiting) were found positive Cost detecting one case:66 US$ (only 1 out of 11 adequate treatment) Cost for preventing one case of congenital syphilis: 730 US$

19 Cost to prevent 1 CASE congenital syphilis BEFORE INTERVENTION730 US$ AFTER INTERVENTION57 US$ Those costs could even decrease further if women visit earlier during pregnancy

20 CONGENITAL SYPHILIS Recommended regimens Early congenital syphilis (up to 2 years of age) Infants with abnormal cerebrospinal fluid: aqueous crystalline benzathine penicillin G IU.KG by intramuscular or intravenousi injection,daily in 2 divided doses for a minimum of 10 days. OR aqueous procaine benzathine penicillin G, IU/KG by intramuscular injection,as a single dailydose for 10 days. Infants with normal cerebrospinal fluid: benzathine penicillin G, IU/Kg by intramuscular injection, at a single session NOTE: Some experts treat all infants with congenital syphilis as if the cerebrospinal fluid findings were abnormal. Antibiotics other than penicillin (i.e erythromycin) are not indicated for congenital syphilis except in cases of severe allergy to penicillin. Tetracyclines should not be used in young children.
