Methods: The MTN-016 pregnancy registry is a prospective observational cohort in which participants who became pregnant during MTN effectiveness studies or those with planned exposures in pregnancy safety studies are monitored for adverse obstetric outcomes; infants from these pregnancies are followed through the first year of life. Registry enrollment systematically excludes termination of pregnancy and early pregnancy loss, including early non-viable pregnancies with a transient positive test at a monthly visit, as these data are captured in parent protocols. For VOICE participants enrolled into the registry from Uganda, Zimbabwe and South Africa, we describe baseline demographic characteristics and key reasons for non-enrollment as reported by site investigators. Results: Among 5029 VOICE participants with over 5425 person-years (py) of follow-up, there were 424 pregnancies (7.8/100 py) and 201 live births. Of these pregnancies, 261 (62%) were eligible for MTN-016. The average age of women who became pregnant during VOICE was 24, with 24% of women married at baseline. Of these, 213/261 (82%) women and 185/201 (92%) of their infants enrolled in MTN-016 (average maternal age 25 years, 33% married). Reasons for non-enrollment of eligible participants into MTN-016 included additional study visit burden and employment. Cultural customs related to temporary relocation to rural areas during the postnatal period and the limitation of public access to newborns were also cited as barriers to enrollment. Conclusions: In this pregnancy exposure registry for candidate HIV prevention agents, the majority of eligible women from VOICE and their infants were enrolled. Study visit burden and local cultural customs may impact the enrollment of mothers and their infants into a pregnancy registry protocol.

Background: Although ARVs and public awareness is being used to eliminate new HIV infections among infants, limited information indicating their impact on the trend of HIV prevalence among infants born to HIV infected mothers exists. This study determined the trend of HIV infection among infants born to HIV infected mothers in relation to specific ARV administration. Also assessed the knowledge about HIV transmission between mothers and infants. Methods: In a cross-sectional study, dried blood spot samples (2010, n = 4210; 2011, n = 4093; 2012, n = 4686; 2013, n = 3080) collected from infants aged £ 18 months. These samples were analyzed at KEMRI-CIPDCR using PCR assay. Some mothers who received public health education were pregnant. All mothers were put on anti-retroviral drugs during and after delivery. Results: Out of the total number of samples tested 9.7%; 8.5%; 7.9%; 7.2% were HIV positive in 2010; 2011; 2012; 2013 respectively. The prevalence of HIV in infants whose mothers had been put on ARVS was as follows: AZT + NVP + 3TC was 10.4%, 9.1%, 6.3%, 6.0% in 2010; 2011; 2012, 2013 respectively. HAART was 7.1%; 6.1%; 4.7%; 3.9% in 2010; 2011; 2012, 2013 respectively. SdNVP was 10.3%; 7.4%; 6.2%; 6.0% in 2010; 2011; 2012; 2013 respectively. Those mothers who had not been given any ARV had their infants with HIV prevalence reaching 11.2%; 12.6%; 12.7%; 12.9% in 2010; 2011; 2012; 2013 respectively. Those mothers who were aware that ARVs reduce transmission of HIV from mother to child were 30%vs70%; not breastfeeding were 37%vs81% and Delivery at the hospital were 43%vs89% before and after public health awareness respectively. Conclusions: Direct relationship between specific ARV administration and HIV infection among infants exists. This is evident by the fact that HIV prevalence appeared to decrease with subsequent years of provision of specific drugs. HAART seemed to provide greater impact in HIV prevention compared to others. There is need for intensified awareness among reproductive women to help in reduction of transmission.

The MTN-016 study is the first pregnancy exposure registry for anti-HIV PrEP and microbicide agents. We evaluated OB and infant outcomes for registrants enrolled from third trimester TFV gel exposure studies. Methods: Data were restricted to registrants enrolled from studies with planned TFV vaginal gel exposure: MTN-002 (open label, single dose prior to cesarean) and MTN-008 (2:1 placebocontrolled, 7-day use). Registry study visits occurred before delivery when possible, and at < 1, 1, 6 and 12 months for infants. Infant malformation endpoints were determined by geneticists via independent review of physical exam (PE) and photo data. Results: All 16 MTN-002 and 90% (88/98) of MTN-008 mothers were registered, with 25% (n = 4) of MTN-002 and 97% (n = 86) of MTN-008 participants enrolling prior to known pregnancy outcome. Demographics were similar for MTN-008 enrollees and non-enrollees in the registry. Infant retention at 12 months was 88% (MTN-002) and 80% (MTN-008). One defect (ear canal) was noted in MTN-002, a rate (6%) comparable to the 3% US background rate for malformations (p = 0.51); no defects were noted in infants from MTN-008. Compared to placebo (n = 30), TFV gel (n = 58) was not associated with preterm delivery (1/58 (2%) vs. 2/30 (7%), p = 0.27), postpartum hemorrhage (11/58 (19%) vs. 3/30 (10%), p = 0.36), nonreassuring fetal status (3/58 (5%) vs. 1/30 (3%), p = 1.0), chorioamnionitis (1/58 (2%) vs. 2/30 (7%), p = 0.27), gestational diabetes (0/58 (0%) vs. 1/30 (3%), p = 0.34), or abnormal infant PE findings in the first year of life (14/58 (24%) vs. 8 (27%), p = 1.0). Conclusions: This first report from a novel pregnancy registry suggests third trimester TFV gel exposure is not associated with infant malformation or adverse OB or infant outcomes. Future HIV chemoprevention studies should include safety evaluation, including registry participation, for pregnant mothers and their infants.

and government investments in developing country implementation, vertical HIV transmission persists. In Kenya, an estimated 37,000 to 42,000 infants are infected with HIV annually due to mother-to-child transmission (MTCT). This study explored the reasons for MTCT persistence in areas with overall low transmission rates and PMTCT service provision. Methods: A case-control study of HIV-exposed infants (HEI) enrolled in follow-up care between January and June 2012 was conducted at 20 rural health facilities supported by Family AIDS Care and Education Services (FACES) in Nyanza Province, Kenya. Cases were HEI who turned HIV positive, controls were HEI who remained negative at last test; an equal number of controls were randomly selected after matching based on birth month and gender. Data were abstracted from routine PMTCT registers, HEI cards, and infant forms. Logistic regression analysis was conducted to determine factors associated with HIV infection. Results: Forty-five cases and 45 controls were compared. Maternal, clinical and infant factors associated with HIV-infected infants included poor PMTCT service uptake including late enrolment of infant to follow-up, (OR = 0.14, 95%CI: 0.06 0.38), poor infant prophylaxis adherence (OR = 8.32, 95%CI 3.24 - 21.38), and fewer antenatal (ANC) visits (OR = 0.62, 95% CI: 0.41 - 0.96). Mothers of cases were significantly less likely to report having received clinic level HIV education and counseling compared to controls (OR 0.13, 95%CI 0.04 - 0.54 and OR 0.12, 95% CI 0.03 - 0.46). Maternal disclosure, gestation at first ANC visit, and infant feeding type were not significantly associated. Conclusions: Poor PMTCT service uptake and a reported absence of clinic level HIV education and counseling were associated with MTCT. More emphasis on PMTCT service provision including counseling and education are needed to minimize HIV transmission to infants.

FHI 360, Durham, NC, United States, 2Setshaba Research Centre, Soshanguve, South Africa, 3Impact Research and Development Organization, Kisumu, Kenya Background: Our previous survey research on pre-exposure prophylaxis (PrEP) and risk compensation with women at HIV risk in Bondo, Kenya, and Soshanguve, South Africa, showed that a considerable minority of women may engage in riskier sexual behavior if taking PrEP. We conducted a small qualitative study to explore perceptions of an informed-choice approach to PrEP counseling. This approach promotes condoms but empowers women who are unable or unwilling to use condoms to make informed decisions regarding their sexual health when taking PrEP. Methods: We conducted eight focus groups with women in Bondo and Soshanguve (four per site). We introduced the counseling approach and presented participants with multiple
