Many Sexually Transmitted Infections Disproportionally impact women Asymptomatic Only detected through screening Not vaccine preventable

Preterm birth is common Major cause of perinatal mortality Poor health outcomes High costs of newborn care 4

76% attributable risk percent of NG and preterm birth Belgium

Gonococcal opthalmia neonatorum Untreated maternal gonorrhea may cause blindness in newborn

Chlamydia trachomatis and preterm labor 7

Chlamydia trachomatis Ophthalmia neonatorum Respiratory disease, pneumonia

T. Vaginalis and Preterm Birth

STIs in pregnant women are common Davey-Jones, STD in press

Cadernos de Saude Publica, 2016, in press. Prof. Mariangela Freitas da Silveira Chlamydia trachomatis positivity, Pelotas, Brazil

New Laboratory Diagnosis of STIs

Point-of-care PCR for CT/NG Vaginal swabs, endocervical/urethral swabs and urine with closed extraction system Large sample volume combined with novel fluidics protocol maximizes sensitivity PCR carried out inside the cartridge New controls for specimen adequacy GeneXpert® CT/NG

No Requirement for dedicated PCR area 4 Results in ~ 1 hr POC, random access 3. Binding reagent into port 1 Xpert CT/NG US FDA-cleared in 2012

Prevention of STI-related Complications In Pregnancy

Prior Work: CT Screening Pilot Study 2 large urban hospitals in Lima, Peru Instituto Nacional Materno Perinatal (INMP) Hospital Nacional Arzobispo Loayza (HNAL) Cabeza J, et al, CDC STD 2014; STI Journal, in review

Chlamydia Study Implementation Flowchart Pregnant woman informed about study Pregnant woman informed about study Participant Screening/eligibility confirmation Informed consent Chlamydia screening: Self collected vaginal swab Participant Screening/eligibility confirmation Informed consent Chlamydia screening: Self collected vaginal swab Questionnaire Telephone contact of patients with positive result and appointment for treatment (patient and partner) Patient treatment Partner treatment Appointment for test of cure Patient treatment Partner treatment Appointment for test of cure Test of cure: Self collected vaginal swab

Hologic APTIMA DTS 400 Chlamydia trachomatis nucleic acid amplification test

High Acceptability and Feasibility, Peru High Acceptability: 93.5% (603 enrolled / 646 approached) Reasons refused (n=43): No time, afraid of test, unaccompanied minor

STI Prevalence and Demographics, Peru Chlamydia trachomatis: 10% (60 /600) Average age: 27.2 years Average gestational age: 26.3 weeks Cabeza J, et al, STI, 2015

Excellent Treatment Outcomes, Peru 60 patients contacted: 59/60 (98%) treated Partner treatment Methods: Patient-delivered 34 (56%) Concomitant DOT 21 (35%) No partner 4 ( 7%) No Treatment 1 ( 2%)

Prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis (n=300) was moderate

India

N=420

Ongoing STI screening in pregnancy projects Kinshasa, Democratic Republic of Congo Pretoria, South Africa Hanoi, Vietnam

Summary Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis are common and under-recognized maternal infections that few countries address Research is urgently need to demonstrate to policy makers the benefits of routine screening and treatment of STIs in pregnancy We have the tools, let’s realize the potential to save lives at birth 35
