Abstract
INTRODUCTION Pregnancy and the postpartum period is a difficult time for women living with HIV (WLWH) and postpartum engagement with HIV care is often reduced, with implications for health and well-being. We aimed to explore the postpartum health experiences of WLWH in relation to engagement in HIV care. METHODS The NESTOR (iNvESTigating the pregnancy and pOst-paRtum health experience of women living with HIV) study was a UK based qualitative semi-structured interview study. 61 eligible women were identified. We used a purposive sampling technique to recruit women with differing levels of engagement in HIV care. Interviews were conducted via telephone or video call. Interviews were audio recorded and fully transcribed. We used a thematic approach for data analysis, and two researchers independently coded the data and established the key themes. RESULTS 11 of 61 (18%) eligible women participated in the interviews, and the three main themes were 'infant feeding decisions', 'managing the risk of mother to child transmission', and 'managing the knowledge of their HIV status'. These themes offer detailed insights into the significant psychological and emotional challenges these women had experienced, and the practical support from healthcare professionals in both HIV and maternity services that had enabled them to navigate those challenges. DISCUSSION There have been life-changing developments in the treatment and care for people living with HIV. However, even in the U = U (undetectable = untransmittable) era, traditional concerns about breastfeeding, risk of transmission to the infant and stigma continue to shape the postpartum experience of WLWH. As these impact on their emotional and psychological wellbeing, support in these areas needs to be prioritised.

Abstract
BackgroundDespite major advances in the care of pregnant women living with HIV (WLHIV), they remain at increased risk of adverse pregnancy outcomes. This study assesses recent developments in management and outcomes of pregnant WLHIV at a tertiary obstetric unit in the United Kingdom.MethodsWe conducted a retrospective cohort study of WLHIV delivering at the John Radcliffe Hospital, Oxford, during 2008–2019. Detailed data was collected for maternal, virological, obstetric, and perinatal characteristics. To determine changes over time, data from the periods 2008–13 and 2014–19 were compared.ResultsWe identified 116 pregnancies in 94 WLHIV. Between 2008–2013 and 2014–2019, the rate of preconception HIV diagnosis increased from 73 to 90% (p = 0.021) and the proportion of WLHIV on combination ART (cART) at conception increased from 54 to 84% (p = 0.001). The median gestation at which cART was initiated antenatally decreased from 22+1 to 17+1 weeks (p = 0.003). In 2014-2019, 41% of WLHIV received non-nucleoside reverse transcriptase inhibitor-based cART, 37% protease inhibitor-based cART, and 22% of cART regimens contained an integrase inhibitor. The proportion of WLHIV with a viral load <50 copies/mL at delivery rose from 87 to 94% (p = 0.235). Sixty-six percent of WLHIV delivered by Cesarean section, with a significant decrease over time in the rate of both planned (62–39%, p = 0.016) and actual (49–31%, p = 0.044) elective Cesarean. Perinatal outcomes included one case of perinatal HIV transmission (0.86%), 11% preterm birth, 15% small-for-gestational-age, and 2% stillbirth. There was an association between a viral load >50 copies/mL at delivery and preterm delivery (p = 0.0004).ConclusionVirological, obstetric, and perinatal outcomes of WLHIV improved during the study period. Implementation of national guidance has led to an increase in preconception diagnosis and treatment, earlier initiation of antenatal treatment, a reduction in the number of women with a detectable viral load at delivery, and an increase in vaginal deliveries.

Abstract
BACKGROUND Strategies for prevention of HIV-1 mother-to-child transmission (PMTCT) have been continuously optimized. However, cases of vertical transmission continue to occur in high-income countries. OBJECTIVES To investigate changes in PMTCT strategies adopted by Italian clinicians over time and to evaluate risk factors for transmission. METHODS Data from mother-child pairs prospectively collected by the Italian Register, born in Italy in 1996-2016, were analyzed. Risk factors for MTCT were explored by logistic regression analyses. RESULTS Six thousand five hundred three children (348 infections) were included. In our cohort, the proportion of children born to foreign mothers increased from 18.3% (563/3078) in 1996%-2003% to 66.2% (559/857) in 2011-2016 (P < 0.0001). Combination neonatal prophylaxis use significantly (P < 0.0001) increased over time, reaching 6.3% (56/857) after 2010, and it was largely (4.2%) adopted in early preterm infants. The proportion of vaginal deliveries in women with undetectable viral load (VL) increased over time and was 9.9% (85/857) in 2011-2016; no infection occurred among them. In children followed up since birth MTCT, rate was 3.5% (96/2783) in 1996-2003; 1.4% (36/2480) in 2004-2010; and 1.1% (9/835) in 2011-2016. At a multivariate analysis, factors associated with MTCT were vaginal delivery with detectable or missing VL or nonelective caesarean delivery, prematurity, breastfeeding, lack of maternal or neonatal antiretroviral therapy, detectable maternal VL, and age at first observation. Previously described increased risk of offspring of immigrant women was not confirmed. CONCLUSIONS Risk of MTCT in Italy is ongoing, even in recent years, underling the need for implementation of the current screening program in pregnancy. Large combination neonatal prophylaxis use in preterm infants was observed, even if data on safety and efficacy in prematures are poor.

Abstract
Objective: To evaluate perinatal outcomes in human immunodeficiency virus (HIV) infected pregnant women in Turkey. Material and Methods: Maternal characteristics, pregnancy complications, laboratory findings including HIV load, CD4 cell count, CD4/CD8 ratio, neonatal features and final HIV status of the baby were retrospectively analyzed. Results: The sample included 26 singleton pregnancies, from 25 HIV-infected women. The ethnicities were Turkish (n=18), East European (n=4), Asian (n=2) and African (n=2). The majority (76.9%) was aware of their HIV status before becoming pregnant. Four cases (15.3%) were diagnosed during pregnancy and two (7.8%) at the onset of labor. The results for median HIV viral load, CD4 count, and CD4/CD8 ratio at birth were 20 copies/mL (0-34 587), 577/mm3 (115-977), and 0.7 (0.1-1.9), respectively. The HIV viral load rate was 5.5% in eighteen women taking anti-retroviral treatment. The rates of gestational diabetes mellitus, gestational hypertension, intrauterine growth restriction, and preterm delivery were 3.8%, 3.8%, 7.6%, and 8% (numbers are 1;1;2;2), respectively. The mean gestational week at birth was 38 weeks and mean birthweight is 2972±329 g. Two babies were congenitally infected with HIV (infection rate of 8.3%). There was one needle-related accident during surgery. Conclusion: Timely diagnosis of HIV infection during pregnancy is important for preventing mother to child transmission. HIV infected women may give birth to HIV negative babies with the help of a multidisciplinary team, composed of perinatology, infectious diseases, and pediatrics specialists.

The effects of MAPK p38α on AZT resistance against reactivating HIV-1 replication in ACH2 cells. Mol Cell Biochem 2019; 462:41-50. [PMID: 31432386 DOI: 10.1007/s11010-019-03608-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2019] [Accepted: 08/10/2019] [Indexed: 02/08/2023]
Abstract
Antiretroviral therapy (ART) has remarkably decreased HIV-related mortality. However, drug-resistant HIV variants pose a potential threat to the long-term success of ART. Both HIV mutants and host factors can cause HIV drug resistance. Using susceptible ACH2 cells chronically infected with HIV-1, we examined the effects of MAPK p38α on AZT resistance against reactivating HIV-1 replication that can be activated by HIV-1 superinfection. We found that HIV-1 superinfection induced more viral production, which was diminished by p38 inhibitor, SB203580, and by AZT in cells infected with non-AZT-resistant HIV-1 strain MN. p38α expression can resist action of AZT in inhibition of HIV-1 replication with increased expression of transcription factor, NF-ĸBp65, SP1, and c-Fos through activation of TCR-related pathways with upregulation of CD3, TCRα, TCRβ, Zap-70, PKC, PLCγ1, GRB2, and PI3K/Akt expression. In HIV-1 MN superinfection under AZT treatment, expression of p38α led to HIV vif expression and inhibited APOBEC3G expression. We also investigated effects of p38α on gp130/JAK-STAT pathways, in which p38α increased expression of protein, gp130, EGFR, Jak2, STAT1, STAT3, STAT5, ras, and TF. p38α could induce apoptotic pathways with upregulation of Fas, FADD, Caspase-8, p53, and Bax, and downregulation of Bcl2 expression. These results indicate that p38α plays a positive role in reactivation of viral replication from HIV-1 latent infection and leads to HIV-1 AZT resistance. In conclusion, MAPKp38α can activate HIV-1 replication inhibited by AZT from HIV-1 latent infection and may be used as a latency reversal agent. The activation involves induction of several cell signaling pathways that are required for HIV-1 replication, which may be integrated into future viral remission strategies.

Abstract
INTRODUCTION HIV-1 epidemiology is changing and prevention of mother-to-child transmission (PMTCT) strategies have been continuously optimized over time. However, the correct management of infected women during pregnancy is crucial for PMTCT and cases of vertical transmission continue to occur. OBJECTIVE To review the most recent evidence regarding the prevention of MTCT in resource-rich and resource-limited settings, focalizing on new possible approaches. RESULTS New issues regard the optimal antiretroviral therapy regimen for pregnant women with good immunological control, the use of intrapartum zidovudine (ZDV) in pregnant women with low viral load, the optimization of prophylaxis in the settings where breastfeeding is recommended and use of combined neonatal prophylaxis (CNP) in infants at high-risk for MTCT. Complete viral control, in recent years, has been achieved in most infected pregnant women, has led to change the recommended mode of delivery, since vaginal birth has become a safe option and is now largely recommended. Recent data reported a large use of CNP in preterm infants: this practice may be dangerous, due to the lack of safety data, and its efficacy and effectiveness is unproven. CONCLUSION Data are accumulating on efficacy, effectiveness and safety of different PMTCT strategies in various possible clinical scenarios, however further researches are needed in order to optimize the management of infants at extremely low risk for MTCT as well as in those presenting with high risk for infection.

Abstract
The aim of this study was to describe the obstetrical and virological outcomes in HIV-infected pregnant women who delivered at a district general hospital in south London in the period from 2008 to 2014. Our review identified 137 pregnancies; most (60%, 63/105) of them were unplanned. The commonest mode of delivery was spontaneous vaginal delivery (SVD) (42%, 48/114) followed by emergency Caesarean section (32%, 36/114). Gestational age at delivery was ≥37 weeks in most (84%, 91/106) of the cases. Maternal HIV VL at or closest to delivery was undetectable (<40 copies/mL), <400 copies/mL and >1000 copies/mL in 73% (94/129), 90% (116/129) and 6% (8/129) of the pregnancies, respectively. None of the infants were infected with HIV making the rate of MTCT of HIV 0% (zero). Our study shows that favourable virological and obstetrical outcomes of HIV-infected pregnant women are achievable in non-tertiary HIV treatment centres. Impact Statement What is already known on this subject: Prevention of mother-to-child transmission (MTCT) of HIV has been one of the major public health successes in the last decades. This success was evident by the reduction of MTCT of HIV in the UK from 25.6% in the 1993 to only 0.46% in 2011. Furthermore, many reports from individual providers, mainly from tertiary centres, of HIV care in the UK also showed very low rates MTCT of HIV. What the results of this study add: Our study shows that favourable virological and obstetrical outcomes of HIV-infected pregnant women are achievable in non-tertiary HIV treatment centres. The MTCT of HIV rate in our hospital was zero in the period from 2008 to 2014. What the implications are of these findings for clinical practice and/or further research: Staff caring for pregnant HIV positive women in general hospitals and small-to-medium HIV clinics should liaise closely with each other and utilise the skill-mix within their hospital in order to provide a quality care that is similar to what is achieved in large teaching centres; however, a prompt referral to tertiary hospitals, when indicated, should be facilitated.
