Introduction: HIV treatment recommendations have evolved over time, reflecting both growing availability of new antiretrovirals and accumulating evidence on their safe and effective use. We analysed patterns of antiretroviral use among diagnosed pregnant women living with HIV delivering in the UK and Ireland between 2008 and 2018 using national surveillance data. Methods: All singleton pregnancies with known outcomes and known timing of antiretroviral initiation reported to the National Surveillance of HIV in Pregnancy and Childhood were included. Every individual instance of specific antiretroviral use was the unit of analysis in generating a snapshot of antiretroviral use overall and over calendar time. The final analysis was restricted to the 14 most frequently prescribed antiretrovirals. Results: There were 12 099 singleton pregnancies reported during 2008–2018 and a total of 38 214 individual uses of the 14 most commonly prescribed antiretrovirals, the majority of which were started before conception (70.9%). In 2008, 37.7% (482/1279) of pregnancies were conceived under treatment, reaching 80.9% (509/629) by 2018. Patterns of antiretroviral use have changed over time, particularly for third agents. Between 2008 and 2018 the most frequently used protease inhibitor shifted from lopinavir to darunavir, whereas use of integrase inhibitors increased steadily over time. Conclusions: These national surveillance data enable investigation of the 'real‐world' use of antiretrovirals in pregnancy on a population level. Findings demonstrate mixed responsiveness of antiretroviral prescription to changes in pregnancy guideline recommendations and may also reflect changes in commissioning and in the characteristics of pregnant women living with HIV.

Objectives: We explore trends in linkage to HIV care following diagnosis and investigate the impact of diagnosis setting on linkage in the era of expanded testing. Methods: All adults (aged ≥ 15 years) diagnosed with HIV between 2005 and 2014 in England, Wales and Northern Ireland (EW&NI) were followed up until the end of 2017. People who died within 1 month of diagnosis were excluded (n = 1009). Trends in linkage to outpatient care (time to first CD4 count) were examined by sub‐population and diagnosis setting. Logistic regression identified predictors of delayed linkage of > 1 month, > 3 months and > 1 year post‐diagnosis (2012–2014). Results: Overall, 97% (60 250/62 079) of people linked to care; linkage ≤ 1 month was 75% (44 291/59 312), ≤ 3 months was 88% (52 460) and ≤ 1 year was 95% (56 319). Median time to link declined from 15 days [interquartile range (IQR): 4–43] in 2005 to 6 (IQR: 0–20) days in 2014 (similar across sub‐populations/diagnosis settings). In multivariable analysis, delayed linkage to care was associated with acquiring HIV through injecting drug use, heterosexual contact or other routes compared with sex between men (> 1 month/3 months/1 year), being diagnosed in earlier years (> 1 month/3 months/1 year) and having a first CD4 ≥ 200 cells/μL (> 3 months/1 year). Diagnosis outside of sexual health clinics, antenatal services and infectious disease units predicted delays of > 1 month. By 3 months, only diagnosis in 'other' settings (prisons, drug services, community and other medical settings) was significant. Conclusions: Linkage to care following HIV diagnosis is relatively timely in EW&NI. However, non‐traditional testing venues should have well‐defined referral pathways established to facilitate access to care and treatment. [ABSTRACT FROM AUTHOR]

Objectives Adolescents with HIV infection acquired perinatally or in early childhood are becoming sexually active, but little is known about fertility and pregnancy outcomes. Multicentre data on pregnancy outcomes in this population are described here. Methods A retrospective case note review of pregnant women with perinatal/early acquired HIV infection, conceiving before 1 September 2009 and attending participating centres in the UK and Ireland, was carried out. Results Among 252 women with perinatal/early acquired infection aged 12 years and older under follow-up in 21 centres, 42 pregnancies were reported in 30 women (19 women with a single pregnancy, 10 women with two pregnancies, and one woman with three pregnancies). Fifteen women (50%) had previous AIDS-defining diagnoses. The median age at first reported pregnancy was 18 years (range 14-22 years). Of the 42 pregnancies, 34 (81%) were reportedly unplanned, 31 (74%) involved regular partners, and in 21 (50%) of the 42 pregnancies the partners were reported to be unaware of maternal HIV status. Fifteen of the 42 pregnancies (36%) were electively terminated, six of the 42 (14%) resulted in first-trimester miscarriages and 21 of the 42 (50%) resulted in live births. Maternal viral load was detectable close to delivery in seven of 21 pregnancies (33%). 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. Conclusions 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. [ABSTRACT FROM AUTHOR]

The article provides an introduction to BHIVA guidelines for the management of HIV infection in pregnant women 2012. The aim of the Writing Group was to make these guidelines as clinically relevant and as practical as possible. The guidelines are intended to inform and aid healthcare workers in the management of pregnant women with HIV. A major area of focus of the guidelines is on obstetric management and the proposed starting gestation for women temporarily taking HAART in pregnancy.
