RESUMO

(1) Background: The evidence base for the management of spontaneous viral controllers in pregnancy is lacking. We describe the management outcomes of pregnancies in a series of UK women with spontaneous HIV viral control (<100 copies/mL 2 occasions before or after pregnancy off ART). (2) Methods: A multi-centre, retrospective case series (1999-2021) comparing pre- and post-2012 when guidelines departed from zidovudine-monotherapy (ZDVm) as a first-line option. Demographic, virologic, obstetric and neonatal information were anonymised, collated and analysed in SPSS. (3) Results: A total of 49 live births were recorded in 29 women, 35 pre-2012 and 14 post. HIV infection was more commonly diagnosed in first reported pregnancy pre-2012 (15/35) compared to post (2/14), p = 0.10. Pre-2012 pregnancies were predominantly managed with ZDVm (28/35) with pre-labour caesarean section (PLCS) (24/35). Post-2012 4/14 received ZDVm and 10/14 triple ART, p = 0.002. Post-2012 mode of delivery was varied (5 vaginal, 6 PLCS and 3 emergency CS). No intrapartum ZDV infusions were given post-2012 compared to 11/35 deliveries pre-2012. During pregnancy, HIV was detected (> 50 copies/mL) in 14/49 pregnancies (29%) (median 92, range 51-6084). Neonatal ZDV post-exposure prophylaxis was recorded for 45/49 infants. No transmissions were reported. (4) Conclusion: UK practice has been influenced by the change in guidelines, but this has had little impact on CS rates.

RESUMO

BACKGROUND: Pre-exposure prophylaxis (PrEP) is highly effective and an important prevention tool for African adolescent girls and young women (AGYW), but adherence and persistence are challenging. PrEP adherence support strategies for African AGYW were studied in an implementation study. METHODS AND FINDINGS: HIV Prevention Trials Network (HPTN) 082 was conducted in Cape Town, Johannesburg (South Africa) and Harare (Zimbabwe) from October 2016 to October 2018 to evaluate PrEP uptake, persistence, and the effect of drug level feedback on adherence. Sexually active HIV-negative women ages 16-25 were offered PrEP and followed for 12 months; women who accepted PrEP were randomized to standard adherence support (counseling, 2-way SMS, and adherence clubs) or enhanced adherence support with adherence feedback from intracellular tenofovir-diphosphate (TFV-DP) levels in dried blood spots (DBS). PrEP uptake, persistence through 12 months (no PrEP hold or missed visits), and adherence were assessed. The primary outcome was high adherence (TFV-DP ≥700 fmol/punch) at 6 months, compared by study arm. Of 451 women enrolled, median age was 21 years, and 39% had curable sexually transmitted infections (STIs). Most (95%) started PrEP, of whom 55% had uninterrupted PrEP refills through 12 months. Of those with DBS, 84% had detectable TFV-DP levels at month 3, 57% at month 6, and 31% at month 12. At 6 months, 36/179 (21%) of AGYW in the enhanced arm had high adherence and 40/184 (22%) in the standard adherence support arm (adjusted odds ratio [OR] of 0.92; 95% confidence interval [CI] 0.55, 1.34; p = 0.76). Four women acquired HIV (incidence 1.0/100 person-years), with low or undetectable TFV-DP levels at or prior to seroconversion, and none of whom had tenofovir or emtricitabine resistance mutations. The study had limited power to detect a modest effect of drug level feedback on adherence, and there was limited awareness of PrEP at the time the study was conducted. CONCLUSIONS: In this study, PrEP initiation was high, over half of study participants persisted with PrEP through month 12, and the majority of young African women had detectable TFV-DP levels through month 6 with one-fifth having high adherence. Drug level feedback in the first 3 months of PrEP use did not increase the proportion with high adherence at month 6. HIV incidence was 1% in this cohort with 39% prevalence of curable STIs and moderate PrEP adherence. Strategies to support PrEP use and less adherence-dependent formulations are needed for this population. TRIAL REGISTRATION: ClinicalTrials.gov NCT02732730.

RESUMO

INTRODUCTION: There are few data regarding the tolerability, safety, or efficacy of antenatal atazanavir. We report our clinical experience of atazanavir use in pregnancy. METHODS: A retrospective medical records review of atazanavir-exposed pregnancies in 12 London centres between 2004 and 2010. RESULTS: There were 145 pregnancies in 135 women: 89 conceived whilst taking atazanavir-based combination antiretroviral therapy (cART), "preconception" atazanavir exposure; 27 started atazanavir-based cART as "first-line" during the pregnancy; and 29 "switched" to an atazanavir-based regimen from another cART regimen during pregnancy. Gastrointestinal intolerance requiring atazanavir cessation occurred in five pregnancies. Self-limiting, new-onset transaminitis was most common in first-line use, occurring in 11.0%. Atazanavir was commenced in five switch pregnancies in the presence of transaminitis, two of which discontinued atazanavir with persistent transaminitis. HIV-VL < 50 copies/mL was achieved in 89.3% preconception, 56.5% first-line, and 72.0% switch exposures. Singleton preterm delivery (<37 weeks) occurred in 11.7% preconception, 9.1% first-line, and 7.7% switch exposures. Four infants required phototherapy. There was one mother-to-child transmission in a poorly adherent woman. CONCLUSIONS: These data suggest that atazanavir is well tolerated and can be safely prescribed as a component of combination antiretroviral therapy in pregnancy.

RESUMO

BACKGROUND: Chronic subdural hematoma is a common presentation to the neurosurgical practice that tends to occur among the elderly. METHODS: We identify a rare occurrence of a chronic subdural hematoma in a young and otherwise healthy female patient who denied a traumatic brain injury. RESULTS: Upon reviewing the literature, we found only one reported case of a spontaneous nature in a young patient. The subtle presentation of headaches and absence of neurological deficit could be mistaken as migraine and result in a delay in obtaining imaging and necessary treatment. In this report, we present a 22-year-old patient who complained of persistent headaches and was neurologically intact on examination. Cranial computed tomography revealed the presence of a right-sided chronic subdural hematoma; this was followed by magnetic resonance imaging plus angiogram, which ruled out the presence of a vascular abnormality. A burr-hole craniostomy procedure was used that resulted in resolution of symptoms. CONCLUSION: Without a heightened clinical suspicion, a similar presentation could be missed, resulting in delayed management.

RESUMO

OBJECTIVES: To document postpartum disease-free survival of HIV-infected women taking antiretroviral therapy (ART) during pregnancy. METHODS: Laboratory and clinical data were collected on all HIV-infected pregnant women delivering from 1998 to 2002 and followed up until September 2004 at 6 hospitals in London. Mothers were grouped according to receipt of zidovudine monotherapy (ZDVm), highly active antiretroviral therapy (HAART) given during and continued after pregnancy (cHAART), and short-term HAART given during pregnancy and discontinued on delivery (START). RESULTS: Eight-five women took ZDVm, 155 took cHAART, and 71 took START. The mean follow-up for all mothers was 33 months, with a total of 847 person-years. At the first antenatal clinic (ANC) visit, 72% of women were in Centers for Disease Control and Prevention (CDC) stage A, 85% were treatment naive, and the ZDVm group had a median HIV viral load (VL) 10-fold less than those mothers who started HAART during pregnancy. At last follow-up, 1 patient had died and 6 (1.9%) had progressed to CDC stage C; 62% of all women, including a quarter of the ZDVm group, were receiving HAART for their own health; and 83% of all mothers had a VL <50 HIV RNA copies/mL of plasma regardless of whether they were on treatment or not. CONCLUSIONS: The median-term postpartum prognosis of HIV-infected pregnant women with access to HAART is good. Exposure to short-course ZDVm or START during pregnancy did not jeopardize their response to subsequent therapy.
