Four infants required neonatal intensive care, three of

whom were delivered preterm. One infant is HIV infected, there are ongoing concerns about the development of three of 21 infants (14%), and two of 21 (10%) have been fostered. Despite access to ongoing sexual health and contraceptive services, unplanned pregnancies are occurring in young women growing up with HIV. Pregnancy care and prevention of onward transmission require complex case management for this emerging population. Where combination antiretroviral therapy (cART) is available, perinatally see more acquired HIV infection has become a chronic disease of childhood [1]. High uptake of antenatal testing, interventions to reduce mother-to-child transmission (MTCT), improved survival, and later age at presentation among children Torin 1 born abroad mean that the average age of perinatally infected children in many European cohorts is now over 12 years [2]. These adolescents are facing the complex task of negotiating sexual relationships with a disease that is transmissible both to partners and to future offspring [3]. Reproductive health, contraceptive use and pregnancy outcomes have been extensively studied in horizontally infected women, but less is known about the reproductive health of perinatally infected women. The long-term outcomes for babies born to mothers who have lived with HIV throughout

puberty, growth and development, with extensive exposure to antiretroviral therapy (ART), are not yet well understood. Health professionals in 21 centres in England,

Wales and Immune system Ireland, caring for young women infected with HIV either perinatally or in early childhood, contributed data via the HIV in Young People Network (www.hypnet.org.uk), a multidisciplinary network of health professionals and voluntary sector representatives working with young people living with HIV infection. Clinicians were asked to report the number of young women aged 12 years and over with presumed perinatal/early acquired HIV infection cared for in their centre, and how many reported pregnancies before September 2009. For each young woman who had been pregnant, a structured proforma was completed by case note review. Viral loads (VLs) and CD4 cell counts closest to the times of conception and delivery were requested. Data were entered into an Excel spreadsheet and descriptive analyses undertaken. An adolescent was considered to have perinatally acquired HIV infection if her own mother had presumed or confirmed HIV infection and she was diagnosed at under the age of 16 years in the absence of other risk factors. Reports were compared with national surveillance data reported to the National Study of HIV in Pregnancy and Childhood (NSHPC; methods available at www.nshpc.ucl.ac.uk and [4]).
