Abstract
South Africa is the epicentre of the global HIV pandemic, with 13.9% of its population infected. Preeclampsia (PE), a hypertensive disorder of pregnancy, is often comorbid with HIV infection, leading to multi-organ dysfunction and convulsions. The exact pathophysiology of preeclampsia is triggered by an altered maternal immune response or defective development of maternal tolerance to the semi-allogenic foetus via the complement system. The complement system plays a vital role in the innate immune system, generating inflammation, mediating the clearance of microbes and injured tissue materials, and a mediator of adaptive immunity. Moreover, the complement system has a dual effect, of protecting the host against HIV infection and enhancing HIV infectivity. An upregulation of regulatory proteins has been implicated as an adaptive phenomenon in response to elevated complement-mediated cell lysis in HIV infection, further aggravated by preeclamptic complement activation. In light of the high prevalence of HIV infection and preeclampsia in South Africa, this review discusses the association of complement proteins and their role in the synergy of HIV infection and preeclampsia in South Africa. It aims to identify women at elevated risk, leading to early diagnosis and better management with targeted drug therapy, thereby improving the understanding of immunological dysregulation.

Abstract
PURPOSE OF REVIEW The primary goal of this review article was to determine whether the three RAAS-associated SNPs, Renin-rs16853055, AGT-rs3789678 and ACE-rs4305 are genetically linked to the development of hypertension in preeclampsia. The secondary goal was to establish if there was a link between these SNPs and HIV infection. RECENT FINDINGS There is a paucity of findings related to the aforementioned SNPs and preeclampsia. There are no recent findings on the rs16853055 renin polymorphism. The rs3789678 angiotensinogen polymorphism correlated significantly with gestational hypertension. The rs4305 ACE polymorphism showed no significant association with the development of pregnancy-induced hypertension. There are conflicting findings when determining the relationship between ethnicity and the predisposition of preeclampsia and hypertension in relation to the discussed RAAS-associated SNPs. To date, the association between RAAS-associated SNPs and preeclamptic women co-morbid with HIV in South Africa has revealed that certain alleles of the AGT gene are more prominent in HIV-infected PE compared to normotensive pregnant HIV-infected women.

Maternal and Newborn Outcomes of SARS-CoV-2/COVID-19 and Pregnancy: Parallels and Contrasts with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome. MEDICAL RESEARCH ARCHIVES 2024; 12:10.18103/mra.v12i4.5205. [PMID: 39118854 PMCID: PMC11309002 DOI: 10.18103/mra.v12i4.5205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 08/10/2024]
Abstract
Purpose of Review Our review aims to compare and contrast Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome and SARS-CoV-2/COVID-19's impact on maternal and neonatal outcomes. We have made significant progress in Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome prevention and treatment over the last few decades. Drawing on empirical evidence with past public health crises can offer valuable insights into dealing with current and future pandemics. Therefore, it is imperative to conduct a comparative analysis of the resemblances and disparities existing between Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome and SARS-CoV-2/COVID-19.This research endeavor represents a pioneering and all-encompassing examination, aiming to discern and comprehend the parallels and contrasts in the respective impacts of SARS-CoV-2 and Human Immunodeficiency Virus on pregnancy. Recent Findings Based on the current evidence, there is no indication that pregnancy increases women's susceptibility to acquiring Human Immunodeficiency Virus or SARS-CoV-2. Nevertheless, the state of being pregnant was correlated with the worsening of diseases and their progression. Both Human Immunodeficiency Virus and SARS-CoV-2 pose increased risks of maternal mortality and several obstetric complications, including premature birth and pre-eclampsia. While the vertical transmission of Human Immunodeficiency Virus is well-established, a comprehensive understanding of the vertical transmission of SARS-CoV-2 remains elusive, emphasizing the need for further investigations. Initial data suggest low SARS-CoV-2 vertical transmission rates in the setting of proper preventative interventions and universal screening. A cesarean delivery could reduce the risk of mother-to-child transmission in Human Immunodeficiency Virus-infected women with high viral loads or poor adherence to antiretroviral therapy (ART). However, it did not offer additional protection for Human Immunodeficiency Virus-infected women who adhered to Adherence to Antiretroviral Therapy or those with COVID-19. Human Immunodeficiency Virus and SARS-CoV-2 were linked to neonatal complications such as stillbirth, low birth weight, and neonatal intensive care unit (ICU) admissions. The universal testing of both pregnant patients and neonates is an effective strategy to prevent the spread and complications of both Human Immunodeficiency Virus and SARS-CoV-2. Human Immunodeficiency Virus control largely relies on preventing vertical transmission and medications during pregnancy and postpartum, whereas safety behaviors and vaccines have proven effective in preventing SARS-CoV-2 vertical transmissions. Summary This review aims to compare and contrast the impact of Human Immunodeficiency Virus and SARS-CoV-2 on pregnancy outcomes, vertical transmissions, delivery modalities, neonatal outcomes, and clinical management. SARS-CoV-2 and Human Immunodeficiency Virus were associated with significant obstetric-related complications, making close clinical monitoring and preparation essential. Integration of SARS-CoV-2/COVID-19 management with reproductive health services is crucial to ensuring maternal and neonatal outcomes. Our review is not only the first to establish a groundwork for the current state of knowledge and its clinical implications on this topic, but it also sheds new insights for future research directions.Comparing Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome and SARS-CoV-2 in terms of their impact on maternal and neonatal outcomes provides valuable insights despite their differences. Leveraging Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome research can help understand SARS-CoV-2 effects on pregnancy. Both infections pose risks to pregnant individuals and their fetuses, leading to increased maternal mortality and complications. Identifying common patterns and risk factors can improve clinical management for pregnant individuals with SARS-CoV-2. While a direct observational study for this comparison may not be feasible, comparing with Human Immunodeficiency Virus offers an ethical and practical approach. However, specific studies on SARS-CoV-2 are still necessary to gather detailed data on maternal and fetal outcomes.

Abstract
Lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1) serves as a prominent marker for lymphatic endothelial cells (LECs) and is pivotal in the process of lymphangiogenesis, a critical factor in cancer development and metastasis. Overexpression of LYVE-1 has been observed in various cancers, where it is recognized as an adverse prognostic indicator. Targeting LYVE-1 has demonstrated inhibitory effects on tumor cell proliferation, migration, and the formation of lymph node metastases both in vitro and in vivo. While extensive research has focused on the role of LYVE-1 in cancer cells, its involvement in virus infection and associated diseases remains largely unexplored. This review consolidates recent findings regarding the expression of LYVE-1 and its functions in lymphangiogenesis during various viral infections and the development of related diseases, with a particular emphasis on Kaposi's sarcoma herpesvirus. Despite the limited available data, it is evident that further studies are essential to comprehensively understand the contribution of LYVE-1 to viral pathogenesis and oncogenesis.

Abstract
Objective In light of complement activation in preeclampsia and HIV infection, this study evaluates the concentration of complement component 3 (C3) in HIV-associated preeclampsia. Method The study population (n = 76) was equally stratified by pregnancy type (normotensive pregnant and preeclampsia) and by HIV status (HIV positive and HIV negative). The plasma concentration of C3 was determined using a Bioplex immunoassay procedure. Results We report a significant increase in C3 concentration in the HIV-negative versus the HIV-positive groups (p < 0.05), regardless of pregnancy type. However, based on pregnancy type and irrespective of HIV status, C3 concentration was similar between normotensive versus preeclampsia. Concentration of C3 was significantly increased in the HIV-positive preeclamptic compared HIV-negative preeclamptic groups (p = 0.04). The correlation of C3 with all study groups was non-significant. Conclusion This study demonstrates that C3 was upregulated in HIV-associated PE compared to HIV- associated normotensive pregnancies. The dysregulation of C3 expression by HIV infection may be attributed to antiretroviral therapy.

Abstract
The Renin-Angiotensin-Aldosterone System (RAAS) is implicated in the pathophysiology of preeclampsia (PE). There is a paucity of data on uteroplacental angiotensin receptors AT1-2 and 4. We evaluated the immunoexpression of AT1R, AT2R, and AT4R within the placental bed of PE vs. normotensive (N) pregnancies stratified by HIV status. Placental bed (PB) biopsies (n = 180) were obtained from N and PE women. Both groups were stratified by HIV status and gestational age into early-and late onset-PE. Immuno-labeling of AT1R, AT2R, and AT4R was quantified using morphometric image analysis. Immunostaining of PB endothelial cells (EC) and smooth muscle cells of spiral arteries (VSMC) displayed an upregulation of AT1R expression compared to the N group (p < 0.0001). Downregulation of AT2R and AT4R expression was observed in PE vs. N group (p = 0.0042 and p < 0.0001), respectively. AT2R immunoexpression declined between HIV+ve and HIV-ve groups, while AT1R and AT4R displayed an increase. An increase in AT1R expression was noted in the EOPE-ve/+ve and LOPE-ve/+ve compared to N-ve/N+ve. In contrast, AT2R and AT4R expression decreased in EOPE-ve/+ve and LOPE-ve/+ve compared to N-ve/N+ve. We demonstrate a significant downregulation of AT2R and AT4R with a concomitant elevated AT1R immunoexpression within PB of HIV-infected PE women. In addition, a decline in AT2R and AT4R with an increase in AT1R immunoexpression in PE, EOPE, and LOPE vs. normotensive pregnancies, irrespective of HIV status. Thus highlighting differential immunoexpression of uteroplacental RAAS receptors based on pregnancy type, HIV status, and gestational age.

Abstract
One of the main causes of maternal and neonatal morbidity and mortality is pre-eclampsia. It is characterized by a high sFlt1/PlGF ratio, according to prior research. Pregestational diseases in mothers may increase the risk of developing pre-eclampsia. Only a few studies have looked at the connection between maternal comorbidities before conception and the sFlt1/PlGF ratio. The most recent information regarding the association between maternal pregestational diseases and the ratio of sFlt1/PlGF is described in this review. The paper also examines current research suggesting that changes in pregnancy hormones and metabolites are related to a high sFlt1/PlGF ratio. Certain maternal disorders have been found to dramatically raise sFlt-1 and sFlt1/PlGF levels, according to an analysis of the literature. There is still debate about the data on the association between the sFlt1/PlGF ratio and maternal disorders such as HIV, acute coronary syndromes, cardiovascular function in the mother between 19 and 23 weeks of pregnancy, thyroid hormones, diabetes, and cancer. Additional research is needed to confirm these findings.

Abstract
This review explored the role of vascular endothelial growth factor receptor-2 (VEGFR-2) in the synergy of preeclampsia (PE), human immunodeficiency virus (HIV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. Downregulation of VEGFR-2 in PE promotes endothelial dysfunction and prevents endothelial cell (EC) migration, proliferation, and differentiation. The HIV-1 accessory protein, tat (trans-activator of transcription), prevents VEGFR-2 signaling via the vascular endothelial growth factor A (VEGF-A) ligand. Combined antiretroviral therapy (cART) may cause immune reconstitution, impaired decidualization, and endothelial injury, thus may be a risk factor for PE development. The VEGF/VEGFR-2 interaction may be associated with SARS-CoV-2-related pulmonary oedema. Endothelial dysfunction and heightened inflammation are both associated with PE, HIV, and SARS-CoV-2 infection; therefore, it is plausible that both characteristics may be exacerbated in the synergy of these events. In addition, this review explored microRNAs (miR) regulating VEGFR-2. An overexpression of miR-126 is evident in PE, HIV, and SARS-CoV-2 infection; thus, modulating the expression of miR-126 may be a therapeutic strategy. However, the involvement of microRNAs in PE, HIV, and SARS-CoV-2 infection needs further investigating. Since these conditions have been evaluated independently, this review attempts to predict their clinical manifestations in their synergy, as well as independently; thereby providing a platform for early diagnosis and therapeutic potential in PE, HIV, and SARS-CoV-2 infection.

Abstract
Introduction pre-eclampsia, a pregnancy-specific condition that occurs after 20 weeks of gestation, is a significant public health problem. In the extant literature, there are still conflicting reports on whether Human immunodeficiency virus (HIV) infection and antiretroviral therapy (ART) affect preeclampsia rates. We, therefore, explored the determinants and neonatal outcomes of preeclampsia among pregnant women living with and without HIV. Methods we reviewed delivery registers and neonatal files from the 1st January 2018, to 30th of September 2019 for women who delivered at Women and Newborn Hospital. The logistic regression model estimated the odds of preeclampsia and described the neonatal outcomes. Results the prevalence of preeclampsia was 7.7% (95% confidence intervals: 6.8 to 8.7). On ART, pregnant women with HIV infection were less likely to develop preeclampsia than those without HIV infection (aOR=0.50; 95% CI: 0.32 to 0.80). However, neonates born to women with preeclampsia were more likely to be admitted to kangaroo mother care than neonates born to normotensive women, regardless of the HIV-exposure status. Conclusion overall, the prevalence of preeclampsia was 7.7%, but it was less common among HIV-infected pregnant women receiving ART. Neonates born from women with preeclampsia are at increased risk of adverse outcomes, including admission to kangaroo mother care. These findings underscore the need for healthcare workers to direct their efforts on early diagnosis and detection of preeclampsia in pregnant women to prevent poor outcomes.

Abstract
OBJECTIVE To evaluate the association of malaria and HIV with pre-eclampsia by evaluating their prevalence among pregnant women. METHODS Using a case-control study design, we randomly sampled the antenatal records of 125 pregnant women with clinician-diagnosed pre-eclampsia (cases) and 125 others without pre-eclampsia (controls) who visited Atua Government Hospital in the eastern region of Ghana between June 2014 and January 2017. All selected records had available routine HIV and malaria test results and were analyzed statistically. RESULTS In all 250 records, 122 (48.8%) were HIV positive and 35 (14.0%) had malaria. Of the 122 HIV-positive pregnant women, 29 (23.8%) were cases and 93 (76.2%) were controls; of the 35 women with malaria, one was in the case group (1/35, 2.9%) and the other 34 (97.1%) were in the control. Group. Pregnant women with pre-eclampsia had lower odds of HIV infection (odds ratio [OR] 0.10, 95% confidence interval [CI] 0.06-0.19: adjusted AOR 0.07, 95% CI 0.04-0.13, P < 0.001). Similarly, pregnant women with pre-eclampsia had lower odds of having malaria infection (OR 0.02, 95% CI 0.00-0.17, P = 0.025; adjusted OR 0.00, 95% CI 0.00-0.01, P < 0.001). CONCLUSIONS Women with pre-eclampsia had lower odds of HIV and malaria infection in pregnancy.

Abstract
BACKGROUND Preeclampsia is a considerable cause of maternal and infant morbidity and mortality. Although its etiology is unknown, preeclampsia has been described as a state of exaggerated maternal inflammatory response. Therefore, it has been hypothesized that preeclampsia would occur less commonly in states of immune deficiency. OBJECTIVE This study aimed to compare the prevalence of treated and untreated HIV infections among preeclamptic cases and controls, determine infant outcomes, and evaluate the association between HIV and preeclampsia after adjusting for known predictor variables, including maternal age, gravidity, body mass index, and smoking. STUDY DESIGN This case-control study investigated the association between preeclampsia and HIV infection using secondary data from an unrelated study. We defined preeclamptic cases as pregnant women who were normotensive until 20 weeks of gestation and thereafter had at least 1 high blood pressure measurement either before or at delivery and proteinuria, defined as protein excretion of ≥300 mg within 24 hours or >2 protein on dipstick urinalysis. The prevalence of HIV infection was compared between cases and controls. Multivariate logistic regression analysis was used to assess the association between preeclampsia and potential confounding variables and reported using odds ratios and 95% confidence intervals. RESULTS There were 571 cases with preeclampsia and 596 normotensive controls included in this study. The median age was 27 years for cases and 26 years for controls (P=.008). Most participants (69%) had ≥2 previous pregnancies with no difference between the cases and controls (P=.176). Overall, 43% of the participants were obese, with a mean body mass index of 29 (interquartile range, 24.5–34.2), with higher proportions of women who were overweight and obese in the group with preeclampsia (P=.031). The prevalence of HIV was significantly lower in cases than in controls (24% vs 30%, respectively; P=.014). Compared with 16% of infants born preterm to normotensive controls, 48% of infants were born preterm born to women with preeclampsia (P<.001). Compared with 14% of infants born with low birthweight to normotensive controls, 53% of infants were born with low birthweight to women with preeclampsia (P<.0001). Untreated HIV infection was negatively associated with preeclampsia (unadjusted odds ratio, 0.330; 95% confidence interval, 0.197–0.552; P<.0001), whereas factors associated with preeclampsia were advanced maternal age (odds ratio, 1.673; 95% confidence interval, 1.209–2.316; P=.002) and obesity (odds ratio, 1.611; 95% confidence interval, 1.023–2.537; P=.040). After adjusting for maternal age, gravidity, smoking, and body mass index in the multivariate regression, only obesity remained significantly associated with preeclampsia (adjusted odds ratio, 1.624; 95% confidence interval, 1.024–2.575; P=.039). CONCLUSION Before the large-scale rollout of antiretroviral therapy in a setting with a high burden of HIV and preeclampsia, untreated HIV infection was found to have a protective effect against preeclampsia. The protective effect against preeclampsia was not apparent for HIV infection treated with antiretroviral therapy.

Abstract
Introduction: This review explores angiogenesis, vascular dysfunction, the complement system, RAAS, apoptosis and NETosis as potential pathways that are dysregulated during preeclampsia, HIV infection and ART usage. Results: HIV-1 accessory and matrix proteins are protagonists for the elevation of oxidative stress, apoptosis, angiogenesis, and elevation of adhesion markers. Despite the immunodeficiency during HIV-1 infection, HIV-1 exploits our cellular defence arsenal by escaping cell-mediated lysis, yet HIV-1 infectivity is enhanced via C5a release of TNF-α and IL-6. This review demonstrates that PE is an oxidatively stressed microenvironment associated with increased apoptosis and NETosis, but with a decline in angiogenesis. Immune reconstitution in the duality of HIV-1 and PE by protease inhibitors, HAART and nucleoside reverse transcriptase, affect similar cellular pathways that eventuate in loss of endothelial cell integrity and, hence, its dysfunction. Conclusions: HIV-1 infection, preeclampsia and ARTs differentially affect endothelial cell function. In the synergy of both conditions, endothelial dysfunction predominates. This knowledge will help us to understand the effect of HIV infection and ART on immune reconstitution in preeclampsia.

Abstract
INTRODUCTION Pre-eclampsia (PE) accounts for 14.8% of maternal deaths in South Africa. Tenascin C (TN-C) is an anti-inflammatory cytokine expressed in the extracellular matrix and may be dysregulated in the hyperinflammatory PE microenvironment. MATERIAL AND METHODS This study examined serum TN-C in normotensive pregnant (n = 36) and pre-eclamptic (n = 36) HIV positive and negative women using an immunoassay. RESULTS TN-C was significantly upregulated in PE vs normotensive pregnant women (p = 0.0075) and HIV-positive vs negative pregnant women (p = 0.0009). TN-C levels across all groups was statistically different (p < 0.0001). CONCLUSION This study demonstrates an elevation of TN-C in HIV-associated PE. The potential benefit of TN-C as a biomarker to detect PE development requires investigation.

Maternal HIV Infection and Spontaneous Versus Provider-Initiated Preterm Birth in an Urban Zambian Cohort. J Acquir Immune Defic Syndr 2021; 87:860-868.

Abstract
OBJECTIVE We investigated the effect of maternal HIV and its treatment on spontaneous and provider-initiated preterm birth (PTB) in an urban African cohort. METHODS The Zambian Preterm Birth Prevention Study enrolled pregnant women at their first antenatal visit in Lusaka. Participants underwent ultrasound, laboratory testing, and clinical phenotyping of delivery outcomes. Key exposures were maternal HIV serostatus and timing of antiretroviral therapy initiation. We defined the primary outcome, PTB, as delivery between 16 and 37 weeks' gestational age, and differentiated spontaneous from provider-initiated parturition. RESULTS Of 1450 pregnant women enrolled, 350 (24%) had HIV. About 1216 (84%) were retained at delivery, 3 of whom delivered <16 weeks. Of 181 (15%) preterm deliveries, 120 (66%) were spontaneous, 56 (31%) were provider-initiated, and 5 (3%) were unclassified. In standardized analyses using inverse probability weighting, maternal HIV increased the risk of spontaneous PTB [RR 1.68; 95% confidence interval (CI): 1.12 to 2.52], but this effect was mitigated on overall PTB [risk ratio (RR) 1.31; 95% CI: 0.92 to 1.86] owing to a protective effect against provider-initiated PTB. HIV reduced the risk of preeclampsia (RR 0.32; 95% CI: 0.11 to 0.91), which strongly predicted provider-initiated PTB (RR 17.92; 95% CI: 8.13 to 39.53). The timing of antiretroviral therapy start did not affect the relationship between HIV and PTB. CONCLUSION The risk of HIV on spontaneous PTB seems to be opposed by a protective effect of HIV on provider-initiated PTB. These findings support an inflammatory mechanism underlying HIV-related PTB and suggest that published estimates of PTB risk overall underestimate the risk of spontaneous PTB.

Abstract
Purpose of the Review: The main objective of this study is to investigate mechanisms associated with gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) in HIV infected pregnant women by looking how placental hormones such as (progesterone and prolactin) and basic haemostatic parameters are regulated in HIV infected pregnancies. Recent Findings: HIV/AIDS are a major global obstetric health burden that lead to increased rate of morbidity and mortality. HIV/AIDS has been associated with the pathophysiology of GDM and HDP. Increased risk of GDM due to highly active antiretroviral therapy (HAART) usage has been reported in HIV infected pregnancies, which causes insulin resistance in both pregnant and non-pregnant individuals. HAART is a medication used for lowering maternal antepartum viral load and pre-exposure and post-exposure prophylaxis of the infant. In pregnant women, HAART induces diabetogenic effect by causing dysregulation of placental hormones such as (progesterone and prolactin) and predispose HIV infected women to GDM. In addition to HIV/AIDS and GDM, Studies have indicated that HIV infection causes haemostatic abnormalities such as hematological disorder, deregulated haematopoiesis process and the coagulation process which results in HDP. Summary: This study will help on improving therapeutic management and understanding of the pathophysiology of GDM and HDP in the absence as well as in the presence of HIV infection by reviewing studies reporting on these mechanism.

Abstract
OBJECTIVE In preeclampsia, there are excessive complement components expressed due to increased complement activation; therefore, this study investigated the concentration of adipsin and C9 in HIV-associated preeclampsia. METHOD The study population (n = 76) was stratified by pregnancy type (normotensive pregnant and preeclampsia) and by HIV status. Serum was assayed for the concentration of adipsin and C9 using a Bioplex immunoassay procedure. RESULTS Maternal weight did not differ (p = 0.1196) across the study groups. The concentration of adipsin was statistically different between the PE vs normotensive pregnant groups, irrespective of HIV status (p = 0.0439). There was no significant difference in adipsin concentration between HIV-negative vs HIV-positive groups, irrespective of pregnancy type (p = 0.6290). Additionally, there was a significant difference in adipsin concentration between HIV-negative normotensive vs HIV-negative preeclampsia (p < 0.05), as well as a difference between HIV-negative preeclampsia vs HIV-positive preeclampsia (p < 0.05). C9 protein expression was not statistically different between the normotensive and PE groups, regardless of HIV status (p = 0.5365). No statistical significance in C9 expression was found between HIV-positive vs HIV-negative groups, regardless of pregnancy type (p = 0.3166). Similarly, no statistical significance was noted across all study groups (p = 0.0774). CONCLUSION This study demonstrates that there is a strong correlation between the up-regulation of adipsin and PE and that adipsin is a promising biomarker to use as a diagnostic tool for PE.

Abstract
Purpose of Review This review investigated the potential role of microRNAs (miRNAs) in the synergy of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, preeclampsia (PE), and human immunodeficiency virus (HIV) infection. Maternal health is a great concern when treating pregnant women fighting this triad of diseases, which is highly prevalent in South Africa. MicroRNAs are involved in fine-tuning of physiological processes. Disruptions to the balance of this minute protein can lead to various physiological changes that are sometimes pathological. Recent Findings MicroRNAs have recently been implicated in PE and have been linked to the anti-angiogenic imbalance evident in PE. Recent in silico studies have identified potential host miRNAs with anti-viral properties against SARS-CoV-2 infection. Studies have demonstrated dysregulated expression of several miRNAs in HIV-1 infection along with the ability of HIV-1 to downregulate anti-viral host microRNAs. Summary This review has highlighted the significant gap in literature on the potential of miRNAs in women with HIV-associated PE in synergy with the novel SARS-CoV-2 infection. In addition, this review has provided evidence of the critical role that the epigenetic regulatory mechanism of miRNA plays in viral infections and PE, thereby providing a foundation for further research investigating the potential of therapeutic miRNA development with fewer side-effects for pregnant women.

Abstract
PURPOSE OF REVIEW The impact of the coronavirus disease 2019 (COVID-19) pandemic is profound, with distressing consequences on many individuals, especially those with co-morbidities. Pregnant women are one such group of individuals who are at in increased risk of contracting COVID-19, due to their immunocompromised state. In South Africa, HIV infection and pre-eclampsia are the leading causes of maternal morbidity and mortality, with South Africa being the HIV epicentre of the world. The relationship between COVID-19 superimposed on HIV infection and preeclampsia is complex and uncertain due to their different immune responses, and therefore requires further research. RECENT FINDINGS Notably evidence suggests that pregnant women with chronic comorbidities (HIV and pre-eclampsia) may be at a greater risk of contracting or encountering complications from COVID-19. Maternal stress, during a pandemic, as well as home delivery have become potential options for pregnant woman. Nonetheless there is currently a paucity of information on the combined effect of COVID-19 in HIV-associated preeclampsia. Understanding the pathogenesis of COVID-19 could potentially aid in developing effective treatment strategies for COVID-19 in HIV associated preeclampsia. This review article presents a comprehensive analysis of the current data in relation to COVID-19 and its effect on pregnant women, including symptoms, pathogenesis and the possible risk of vertical transmission. This paper also reviews its' interactions and effects on preeclamptic and HIV positive pregnant women with suspected or confirmed COVID-19.

Abstract
OBJECTIVE To assess HIV positivity as an apoptotic confounding variable in pregnancies complicated by preeclampsia. METHODS AND MATERIALS Using a Bio-plex Multiplex Immunoassay, Smac and Lamin B concentrations (ng/ml) were analyzed in a buffy coat collected from 128 pregnant women attending a large regional hospital in Durban, South Africa. Study groups consisted of Normotensive and Preeclamptic pregnant women stratified according to their HIV status. All HIV positive groups received highly active antiretroviral therapy (HAART). RESULTS Our findings showed significant (p < .05) upregulation in the levels of both SMAC and LAMIN B in the HIV positive patients and a concomitant downregulation of the same apoptotic makers were observed in preeclampsia regardless of HIV status. CONCLUSIONS These results could be associated with the fact that apoptosis promotes deregulation of mitochondrial dynamics, contributing to the associated severe obstetric events observed in pregnancies among HIV-infected women on HAART.

Abstract
PURPOSE OF REVIEW Both HIV infection and preeclampsia (PE), a pregnancy-specific disorder of hypertension and multi-system organ involvement, have high prevalence rates especially in low-to-middle-income countries. The immunoexpression of specific renin-angiotensin-aldosterone system (RAAS) receptors in the placenta and placental bed interface may forecast the risk of PE. RECENT FINDINGS Preeclampsia is a leading risk factor for mortality worldwide and remains a challenge in HIV-infected individuals especially those on antiretroviral therapy (ART). Irregular RAAS stimulation may be linked to the pathophysiology of hypertension in HIV infection and in PE. The AT1 receptor is expressed across all trimesters of pregnancy, within placental tissue, eliciting vasoconstriction. This increased expression is associated with the severity of PE, implying that the increased expression may be involved in the pathogenesis of this pregnancy disorder. The AT2 receptor expression in normotensive pregnancies was shown to be lower as compared to non-pregnant individuals. Furthermore, in the PE placental bed, the AT2 receptor is the predominant receptor subtype and is found in extravillous trophoblast cells where they facilitate vasodilation. However, AT4R in placentae of PE pregnancies are found to be significantly reduced compared to normotensives pregnancies. The data on the role played by the RAAS pathway in pregnancy is conflicting. Investigation into a tissue-based RAAS with emphasis on immune-expression within the placenta and placental bed may help resolve this conundrum.

Abstract
Background Preeclampsia and eclampsia are common complications of pregnancy globally, including sub-Saharan African (SSA) countries. Although it has a high burden on maternal and neonatal mortality and morbidity, evidence on the risk of the problem is limited. Therefore, the aim of this review was to examine the factors associated with preeclampsia and eclampsia among mothers in SSA countries. Methods We searched article from SSA countries using electronic database MEDLINE, EMBASE, PubMed, CINAHL published in English from January 2000 to May 2020. Two reviewers independently screened, extracted and assessed the quality of the articles. Both random and fixed effect model were used for analysis. Heterogeneity of the studies and publication bias were checked. STATA 16 used for analysis. Results Fifty-one studies met the inclusion criteria and included in this review. The following factors were identified through meta-analysis: being primiparous (OR: 2.52; 95% CI:1.19, 3.86), previous history of maternal preeclampsia/eclampsia (OR:5.6; 95% CI:1.82, 9.28), family history of preeclampsia/eclampsia (OR:1.68; 95% CI:1.26, 2.11), high maternal body mass index (OR: 1.69; 95% CI:1.17, 2.21), chronic hypertension (OR: 2.52; 95% CI:1.29, 3.74), anaemia during pregnancy (OR: 3.22; 95% CI:2.70, 3.75) and lack of antenatal care visits (OR: 2.71; 95% CI:1.45, 3.96). There was inconclusive evidence for a relationship with a number of other factors, such as nutrition and related factors, antenatal care visits, birth spacing, and other factors due to few studies found in our review. Conclusions The risk of preeclampsia and eclampsia is worse among women who have a history of preeclampsia/eclampsia (either themselves or family members), primiparous, obesity and overweight, living with chronic disease, having anaemia during pregnancy and absence from ANC visits. Therefore, investment must be made in women’s health needs to reduce the problem and health service providers need to give due attention to high-risk women.

[PMID: 32596279 PMCID: PMC7305545 DOI: 10.1155/2020/1697657] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/08/2020] [Revised: 05/04/2020] [Accepted: 05/25/2020] [Indexed: 12/12/2022]
Abstract
OBJECTIVES HLA-G, part of the major histocompatibility complex (MHC), is associated with the risk of developing preeclampsia (PE). In this study, we determined the contribution of specific HLA-G polymorphisms on the risk of developing preeclampsia in HIV-infected and uninfected South Africans of African ancestry. METHODS One hundred and ninety-three women of African ancestry were enrolled (74 HIV-uninfected normotensive, 60 HIV-infected normotensive, 34 HIV-uninfected, and 25 HIV-infected preeclamptics). Sanger sequencing of the untranslated region was performed to genotype six SNPs, i.e., 14 bp Ins/Del of rs66554220, rs1710, rs1063320, rs1610696, rs9380142, and rs1707). RESULTS For rs66554220, we have the following results: (a) based on pregnancy type-the Ins/Ins and Del/Ins genotype frequency was higher in preeclampsia (PE) compared to normotensive pregnancies (Ins/Ins vs. Del/Ins, P = 0.02∗: OR (95%CI) = 13.44 (0.7222-249.9); Del/Del vs. Del/Ins, P = 0.03∗: OR (95%CI) = 2.95 (1.10-7.920)); (b) based on HIV status-the Ins/Ins showed both genotypic and allelic association with HIV infection. HIV-infected PE has higher Ins/Ins genotypic and allelic frequencies compared to HIV-uninfected PE (Ins/Ins vs. Del/Ins, P = 0.005∗∗: OR (95%CI) = 21.32 (1.71-4.17); Ins, P = 0.005∗∗; OR (95%IC) = 21.32 (1.71-4.17)). For rs1707, we have the following results: (a) based on pregnancy type-there were CT genotypic frequencies in PE, more especially LOPE compared to normotensive pregnancies (TT vs. CT, P = 0.0092∗∗: OR (95%CI) = 5.(1.39 - 25.64)), and no allelic association was noted; (b) based on HIV status-CT was higher in HIV-infected LOPE compared to uninfected LOPE (TT vs. TC, P = 0.0006∗∗∗: OR (95%CI) = 40.00 (2.89 - 555.1)). For rs1710 and rs1063320, no significant differences in the genotype and allele frequencies were noted based on pregnancy type and HIV status. For rs9380142, we have the following results: (a) based on pregnancy type-no significant differences were noted between normotensive compared to PE pregnancies; (b) based on HIV status-AA genotypes occurred more in the HIV-infected PE group (AA vs. GG, P = 0.02∗: OR (95%CI) = 13.97 (0.73 - 269.4)), while A allelic frequency occurred more in HIV-infected PE, especially LOPE compared to uninfected groups (A vs. G, P = 0.0003∗∗∗: OR (95%CI) = 10.72 (2.380 - 48.32); P = 0.02∗: OR (95%CI) = 9.00 (1.07 - 75.74)). For rs1610696, we have the following results: (a) based on pregnancy type-genotypic and allelic frequencies of CC were higher in PE compared to normotensive pregnancies (CC vs. GG, P = 0.0003∗∗∗: OR (95%CI) = 31.87 (1.861 - 545.9); C, P = 0.0001∗∗∗: OR (95%IC) = 21.91 (2.84 - 169.0)); (b) based on HIV status-GG frequencies were higher in the HIV-infected PE more especially LOPE groups (GG vs. GC, P = 0.02∗: OR (95%CI) = 16.87 (0.81 - 352.1); GG vs. CC, P = 0.0001∗∗∗: OR (95%CI) = 159.5 (13.10 - 1942)). CONCLUSION Selected HLA-G 14 bp polymorphisms (Ins/Ins) and genotypic and allelic differences in rs9380142, rs1610696, and rs1707 are associated with the pathogenesis of preeclampsia in HIV-infected South African women of African ancestry. More genetic studies evaluating the association between preeclampsia and HIV infection are needed to improve diagnosis and antenatal care.

Abstract
In South Africa, pre-eclampsia (PE) and human immunodeficiency virus (HIV) infection are major causes of pregnancy-related deaths. This study aimed to measure serum levels of endothelin-1 (ET-1), endothelial nitric oxide synthase (eNOS), soluble fms-like tyrosine kinase 1 (sFlt-1), soluble endoglin (sEng) and placental growth factor (PlGF) in HIV-infected highly active antiretroviral therapy (HAART)-treated and HIV-uninfected PE and normotensive women to ascertain if HIV/HAART alters their concentrations. Mean sFlt-1 levels were significantly up-regulated in the PE (HIV-uninfected 4.39 ± 1.29; HIV-infected 5.10 ± 1.10 ng/ml) compared to normotensive women (HIV-uninfected 2.59 ± 0.83; HIV-infected 2.20 ± 0.85 ng/ml). Mean PlGF levels were significantly lower in HIV-uninfected PE vs. HIV-infected normotensive women (29.69 ± 4.47 pg/ml vs. 32.86 ± 6.46 pg/ml; p = .002). In conclusion, PE women with HIV exhibited significantly low serum PlGF, ET-1 and eNOS levels. Infection with HIV may have further increased the sFlt-1 levels.IMPACT STATEMENTWhat is already known on this subject? In PE, the numerous identified local and circulating bioactive factors differed in concentrations when compared to normal pregnancy.What do the results of this study add? PE women with HIV exhibited significantly low serum PlGF, ET-1 and eNOS levels as well as increased levels of sFlt-1.What are the implications of these findings for clinical practice and/or further research? Understanding the link between PE, HIV and HAART during pregnancy will improve prognosis, management and treatment strategies for women clinically.

Abstract
OBJECTIVE To evaluate the levels of serum beta-2-glycoprotein I (β2GP1) and clusterin in the duality of Pre-eclampsia and HIV. METHOD Stored serum samples collected from 72 pregnant women were stratified according to the pregnancy type (pre-eclamptic and healthy normotensive groups) and HIV status (positive or negative). A Bio-Plex multiplex immunoassay was used to determine the concentrations of clusterin and β2GP1. RESULTS Clusterin concentrations differed significantly (p = 0.01) between the HIV positive (+) (mean = 123 800 ng/ml; 95 % CI: 105 400-142 200) vs. HIV negative (-) (mean = 92 190 ng /ml; 95 %CI: 75 840-108 500) groups and across all groups (p = 0.0006). Beta-2-glycoprotein I concentration differed significantly based on HIV status (p < 0.0001); HIV+ (mean = 393 649 ng/ml; 95 %CI: 30 300-467 000) vs HIV- (mean = 224 309 ng/ml; 95 %CI: 154 000-294 700) and across all groups (p < 0.0001). No significant difference was observed between normotensive and Pre-eclamptic groups for both clusterin and β2GPI. CONCLUSION Serum concentrations of clusterin and β2GPI were significantly increased in HIV positive pregnancies. It is postulated that both clusterin and β2GPI may have a role in HIV disease progression. These findings need to be confirmed in studies having larger sample sizes and detailed information on anti-retroviral therapy.

Abstract
KwaZulu-Natal has a high burden of HIV infection and high blood pressure, specifically pre-eclampsia (PE) in pregnancy. Follistatin (FS) and granulocyte-colony stimulating factor (G-CSF) are two glycoproteins involved in PE pathogenesis. In light of the high maternal mortality and morbidity in South Africa (SA), we investigated the expression of FS and G-CSF in the duality of HIV-associated PE. Serum samples of normotensive and pre-eclamptic women were analysed using the Bio-Plex Multiplex Immunoassay. FS expression was significantly reduced in pre-eclamptic (median = 372.0, IQR = 719.2) compared to normotensive (median = 1569.0, IQR = 2043.0) (p < 0.0001). Furthermore, we detected significant FS expression across all study groups. There was a significant difference between HIV -ve normotensive (median = 9.0, IQR = 7.0) vs HIV +ve normotensive (median = 12.0, IQR = 5.0) groups. Additionally, G-CSF expression was notably higher in HIV +ve normotensive when compared to all study groups. This study demonstrated a downregulation of FS and G-CSF expression in PE, compared to normotensive pregnancies. This finding may be attributed to oxidative stress and its immunoregulatory role in the hyperinflammatory milieu of PE. HIV status had no effect on both analytes, albeit upregulated due to immune reconstitution emanating from highly active antiretroviral therapy. Our novel findings suggest that FS and G-CSF may have a potential predictor test value in early pregnancy, hence work on this is ongoing.

Abstract
Maternal HIV infection is related to several perinatal adverse outcomes. This study is aimed at establishing whether maternal HIV infection is associated with the development of pre-eclampsia (PE) and eclampsia. We comprehensively searched MEDLINE/PubMed, Web of Science, SCOPUS and Embase databases for relevant studies published up to 20 November 2018, without time and language restrictions. We have limited our literature searches to observational studies in humans. We applied a random-effects model to calculate the relative risks (RR) and 95% confidence intervals (CI) for the meta-analyses. We also systematically reviewed eligible studies to determine the effects of HIV infection on imbalance of angiogenic and anti-angiogenic factors, which are effective in increased risk of PE or eclampsia. We identified a total of 11,186 publications, out of which 22 eligible studies (11 prospective and 11 retrospective cohort studies) comprising 90,514 HIV-positive and 66,085,278 HIV-negative pregnant women were included in meta-analysis. Results of the meta-analyses suggested that maternal HIV infection is not significantly associated with the development of PE (RR, 1.04; 95%CI, 0.89-1.21) and eclampsia (RR, 1.05; 95%CI, 0.63-1.75). Six studies were included to understand the effects of HIV infection on imbalance of angiogenic and anti-angiogenic factors. All six studies demonstrated that HIV infection had no significant effect on expression levels of these factors in pre-eclamptic and normotensive pregnant women. Our study showed that maternal HIV infection was not significantly associated with increased or reduced risks of pre-eclampsia and eclampsia. More well-designed studies with large sample size and well defined outcomes are recommended to confirm or refute the present findings.

Abstract
Purpose of the review: This review highlights the role of angiogenesis, lymphangiogenesis, and immune markers in human immunodeficiency virus (HIV)-associated preeclamptic (PE) pregnancies in an attempt to unravel the mysteries underlying the duality of both conditions in South Africa. Recent findings: Studies demonstrate that HIV-infected pregnant women develop PE at a lower frequency than uninfected women. In contrast, women receiving highly active anti-retroviral therapy (HAART) are more inclined to develop PE, stemming from an imbalance of angiogenesis, lymphangiogenesis, and immune response. Summary: In view of the paradoxical effect of HIV infection on PE development, this study examines angiogenesis, lymphangiogenesis, and immune markers in the highly HIV endemic area of KwaZulu-Natal. We believe that HAART re-constitutes the immune response in PE, thereby predisposing women to PE development. This susceptibility is due to an imbalance in the angiogenic/lymphangiogenic/immune response as compared to normotensive pregnant women. Further large-scale studies are urgently required to investigate the effect of the duration of HAART on PE development.

Abstract
PURPOSE OF REVIEW This review provides a comprehensive insight into the angiogenic profile of hypertensive and normotensive pregnancies compromised by HIV infection. Furthermore, we evaluate the economic implementation of the sFlt-1/PlGF ratio and review the reports on therapeutic apheresis in limiting sFlt-1 production. RECENT FINDINGS In preeclampsia, an increased expression of sFlt-1 triggers angiogenic imbalance. Women of African ancestry have high levels of angiogenic factors than other racial groups. The sFlt-1/PlGF ratio shows promise in the early assessment of preeclampsia, while sFlt-1 apheresis restores angiogenic imbalance. Studies suggest antiretroviral therapy does not impact the angiogenic shift in preeclampsia development. The angiogenic profile in pregnant women of different races influences preeclampsia development. Despite the opposing immune response in HIV infection and preeclampsia, the HIV tat protein strongly mimics vascular endothelial growth factor (VEGF); hence, it is plausible to assume that HIV infection may ameliorate the angiogenic imbalance in preeclampsia.

Abstract
OBJECTIVES Epidermal growth factor (EGF) and Hepatocyte growth factor (HGF) both have tyrosine kinase receptors (EGFR and c-Met) which upon binding, activates and regulates many important cellular processes such as cell survival, growth, proliferation, differentiation, invasion, repair and so forth via the RAS/MAPK/ERK1/2, PI3K/AKT and JAK STAT3 pathways. These processes are crucial for the development of a placenta and other functions in order for a normal pregnancy to occur. Hence, this study determined the concentrations of HGF and EGF to find the correlation between HIV and preeclampsia (PE). STUDY DESIGN A total sample size of n = 80 was used, n = 40 preeclamptic women and n = 40 normotensive women these were further stratified into HIV-positive and HIV-negative women. Analysis of the growth factors were done by using the multiplex Bio-Plex immunoassay method. RESULTS Irrespective of HIV status, based on pregnancy type, EGF in PE women displayed an upregulation compared to normotensive women. However, for HGF no variance was found between pregnancy type. Based on HIV status, regardless of pregnancy type, both HGF and EGF levels were significantly increased in HIV-positive women compared to HIV-negative women. Across all groups for HGF, significant difference was found between HIV-negative normotensive women (lower) vs HIV-positive normotensive women (higher). Nevertheless, for EGF across all groups, a statistically significant decrease was found in HIV-negative normotensive women compared to HIV-positive normotensive women, HIV-positive PE women and HIV-negative PE women. CONCLUSION The study demonstrates that there is a strong association between HIV and PE and that HGF and EGF are promising biomarkers to use as a diagnostic tool for PE.

Abstract
BACKGROUND The complement system is a key component of the innate immune system that plays a vital role in host defense, maintains homeostasis and acts as a mediator of the adaptive immune response. The complement system could possibly play a role in the pathogenesis of HIV infection and preeclampsia (PE), both of which represent major causes of maternal death in South Africa. RECENT FINDINGS The relationship between PE and HIV infection is unclear as PE represents an exaggerated immune response, while HIV infection is associated with a decline in immune activity. Although the complement system works to clear and neutralize HIV, it could also enhance the infectivity of HIV by various other mechanisms. It has been suggested that the dysregulation of the complement system is associated with the development of PE. CONCLUSION There is currently a paucity of information on the combined effect of the complement system in HIV-associated PE. This review highlights the role of the complement system in the duality of HIV infection and PE and provides new insights into this relationship whilst also elucidating potential therapeutic targets.

Abstract
OBJECTIVE This study assesses whether circulating sTie2 and sHER2 are altered in HIV-negative and HIV-positive pregnant normotensive and preeclamptic women. METHODS Serum samples were obtained from 80 pregnant women, stratified into four groups, namely, HIV-negative normotensives (20); HIV-positive normotensives (20); HIV-negative preeclamptics (20); and HIV-positive preeclamptics (20). The concentration of sTie2 and sHER2 was analyzed by Bio-Plex multiplex immunoassay and generated from a standard curve. RESULTS sTie2 differed significantly by pregnancy type (p = 0.0403) but not by HIV status (p = 0.5214). sHER2 did not show a significant difference between normotensive and preeclampsia (p = 0.3677) and by HIV status (p = 0.5249). CONCLUSION Irrespective of HIV status, reduced concentrations of sTie2 were evident in preeclampsia (PE) reflecting a dysregulation of the angiogenic process. sHER2 was similar between pregnancy types, attributable to the oxidative stressed microenvironment which promotes dysregulation of the MAPK and P13K/Akt signaling. HIV status did not influence sTie2 and sHER2 expression, reflecting the immune reconstitution of highly active antiretroviral therapy. sTie2 and sHER2 were not influenced by PE comorbid with HIV infection.

Abstract
PURPOSE OF THE REVIEW This review highlights the role immune cells and markers such as natural killer (NK) cells, cytokines and human leukocyte antigen (HLA-G) play in predisposing HIV-infected women who are on HAART to develop PE, thus contributing to a better understanding and early diagnosis of PE with a subsequent reduction in maternal foetal and neonatal deaths. RECENT FINDINGS Pregnant women infected with the Human Immunodeficiency Virus (HIV) have a 25% risk of mother to child transmission. This risk, however, decreases to 2% if the women is on treatment. Highly active antiretroviral therapy (HAART) is the recommended treatment for both pregnant and non-pregnant women infected with HIV. Treatment with HAART is reported to potentiate predisposition to the development of hypertensive disorders of pregnancy such as pre-eclampsia (PE). Pre-eclampsia accounts for 7-10% of abnormal pregnancies worldwide. Studies demonstrate that pregnant women with HIV have PE at lower frequencies than uninfected women, however, the converse is observed upon HAART initiation. HIV-infected women on HAART exhibit a greater tendency to develop PE, emanating from immune reconstitution induced by HAART. There is paucity of information as to the pathogenesis of PE upon HAART initiation and there are, therefore, controversial data as to whether HAART predisposes women to a lower, equal or higher risk of PE development compared to the general population, further investigations on the impact of HIV infection and HAART on the immune response and rate of PE development in HIV infected pregnant women are urgently needed.

Abstract
OBJECTIVE To determine the level and effect of urinary clusterin (CLU) and glutathione-s-transferase (GST) proteins in normotensive and preeclamptic pregnant women with HIV infection. METHODS The urine concentration of CLU and GST in normotensive (n = 38) and preeclamptic pregnant (n = 38) women stratified by HIV status were estimated using the Bio-Plex® ProTM immunoassay. RESULTS Across the group, a significant down-regulation of CLU (p = 0.039) with a reduced trend in GST was shown in HIV positive preeclampsia. CONCLUSION HIV infection affects the activity of urinary CLU protein in HIV positive preeclampsia. However, the cytoprotective role of these proteins neutralizes the oxidative radicals associated with preeclampsia development through complement response in HIV infection.

Abstract
OBJECTIVE The factors angiopoeitin-2 (Ang-2), endoglin (Eng), and placental growth factor (PlGF) have been implicated in the pathophysiology of preeclampsia (PE). This study assessed their serum levels in HIV-negative and HIV-positive pregnant normotensive and pre-eclamptic women. METHODS Participants were recruited at the antenatal clinic, serum samples were evaluated using the Bioplex Human Cancer Biomarker (panel 2). RESULTS Ang-2 and Eng levels were higher, whilst PlGF levels were lower in the PE compared with the normotensive group. Pregnancy type had no significant effect on Ang-2 and showed a significant interaction with Eng (p < 0.0001) and PlGF (p = 0.0033). HIV status had no significant effect on angiopoeitin-2 (p = 0.4), Eng (p = 0.4), and PlGF (p = 0.7) but the levels were slightly higher in the HIV-negative cohort. CONCLUSIONS This study demonstrates an elevation of Ang-2 and Eng in pre-eclamptic compared with normotensive pregnant women implicating their role in its pathogenesis.

Abstract
BACKGROUND Preeclampsia (PE) is one of the major causes of maternal and perinatal morbidity and mortality, especially in low- and middle-income countries. In recent years, a growing body of literatures suggests that infections by bacteria, viruses, and parasites and their related inflammations play an important role in the pathogenesis of PE. METHODS We searched PubMed, Google scholar, and Cochrane databases using the following search words: "infection and preeclampsia," "bacterial infection and preeclampsia," "viral infection and preeclampsia" and "parasitic infection and preeclampsia." RESULTS The literature review revealed that many bacteria including Helicobacter pylori, Chlamydia pneumonia, and those are involved in periodontal disease or urinary tract infections (UTIs) and some viral agents such as Cytomegalovirus, herpes simplex virus type-2, human immunodeficiency virus, and some parasites especially Plasmodium spp. and Toxoplasma gondii can be effective in development of PE. Inflammation responses against infections has major role in the inducement of PE. The shift of immunological cytokine profile of Th2 toward Th1 and high levels of pro-inflammatory cytokines (TNF-ɑ, IL-12, IFN-γ, etc.), increase of oxidative stress, increase of anti-angiogenic proteins, increase of vascular endothelial growth factor receptor 1 (sVEGFR1), and complement C5a are the main potential mechanisms related to infections and enhanced development of PE. CONCLUSION Thus, early diagnosis and treatment of bacterial, viral, and parasitic infections could be an effective strategy to reduce the incidence of PE.

Abstract
OBJECTIVE To measure and correlate the level of vascular endothelial growth factors A, C, and D in HIV-associated pre-eclampsia. METHODS VEGF-A, VEGF-C, and VEGF-D were measured in serum of 76 normotensive and pre-eclamptic pregnant women stratified by HIV status using Bio-Plex. RESULTS No significant difference was shown between pre-eclamptic and normotensive and between HIV negative and positive women. A strong significant positive correlation was demonstrated between VEGF-A and VEGF-C, VEGF-A and VEGF-D, and VEGF-C and VEGF D (p < 0.0001). CONCLUSION This study demonstrates a significant correlation between VEGF-A, VEGF-C, and VEGF-D and no difference in pre-eclamptic and normotensive pregnant women stratified by HIV status suggesting some neutralization of the immune response in HIV-associated pre-eclampsia.

Abstract
INTRODUCTION Preeclampsia and HIV/AIDS are inflammatory conditions that contribute significantly to adverse maternal and foetal outcomes. The immune reconstitution effects of HAART on inflammatory mediators has not been adequately studied in pregnancy and may impact on the inflammatory cytokine network in women with co-morbid preeclampsia. Our study evaluated changes in pro-inflammatory cytokines IL-2, TNF-α, IFN-γ and IL-6 in HIV infected preeclamptic women on HAART. METHODS A prospective experimental study was conducted at Prince Mshiyeni Memorial Hospital between July 2013 and September 2014. One hundred and ninety three pregnant women were recruited into 4 groups: uninfected normotensive (50; 26%), infected normotensive (45; 23%), uninfected preeclamptic (53; 28%) and infected preeclamptic women (45; 23%). Serum levels of cytokines TNF-α, IFN- γ, IL-2 and IL-6 were determined using commercially available kits and a Cytometric Bead Array (CBA). Comparative data was recorded and analysed descriptively. RESULTS In the control groups (normotensive), significantly lower values were found in IL-2 (p = 0.010), TNF-α (p = 0.045), and IL-6 (p = 0.005); and a non-significant decrease was observed in IFN-γ (p = 0.345) in HIV infected women on HAART compared to uninfected controls. In the experimental group (preeclamptic) women, significantly reduced levels were observed in IL-2 and TNF-α (p = 0.001; p = 0.000) and non-significant decreases were observed in IFN-γ and IL-6 (p = 0.023; p = 0.086) in HIV infected women on HAART compared with uninfected preeclamptic women. Non-significant differences were observed between uninfected preeclamptic and normotensive women. CONCLUSION In uncomplicated/normotensive pregnancies, HIV/HAART is associated with significant decreases in IL-2, TNF-α and IL-6, and in preeclamptic women significant decreases in IL-2 and TNF-α were observed. These findings suggest that HIV/HAART impacts on pro-inflammatory cytokines in women with co-morbid preeclampsia. This provides a platform for further research on immune reconstitution effects of HAART during pregnancy, and the development of potential immune modulation therapies for the management of preeclampsia.

Abstract
OBJECTIVE To explore potential relationships between HIV and highly active anti-retroviral therapy (HAART), and hypertensive disorders of pregnancy (HDP). METHODS A retrospective secondary analysis of maternal-deaths data from the 2011-2013 Saving Mothers Report from South Africa. The incidence of HIV infection amongst individuals who died owing to HDP was determined and comparisons were made based on HIV status and the use of HAART. RESULTS Among 4452 maternal deaths recorded in the Saving Mothers report, a lower risk of a maternal deaths being due to HDP was observed among women who had HIV infections compared with women who did not have HIV (relative risk [RR] 0.57, 95% confidence interval [CI] 0.51-0.64). Further, reduced odds of death being due to HDP were recorded among women with AIDS not undergoing HAART compared with women with HIV who did not require treatment (RR 0.42, 95% CI 0.3-0.58). Notably, among all women with AIDS, a greater risk of death due to HDP was demonstrated among those who received HAART compared with those who did not (RR 1.15, 95% CI 1.02-1.29). CONCLUSION HIV and AIDS were associated with a decreased risk of HDP being the primary cause of death; the use of HAART increased this risk.

Abstract
OBJECTIVE To compare expression of markers of HIV and associated receptors (p24, CD4, CCR5 and ICAM-2) in placentae and umbilical cords of HIV-associated and pre-eclamptic pregnancies to elucidate any association between these conditions in mother-to-child transmission. DESIGN Cross-sectional immunohistochemical analysis of target receptor expression. SETTING Laboratory-based study of primigravidae attending a district hospital in South Africa. POPULATION OR SAMPLE Retrospectively collected placental tissue (stratified into four groups according to HIV status of normotensive and pre-eclamptic participants (n = 20/group). METHOD Immunohistochemistry utilising CD4 (1:1), p24 (1:10), CCR5 (1:80) and ICAM-2 (1:100) antibodies was performed using light microscopy for image acquisition and analysis. MAIN OUTCOME MEASURES Evaluate the expression of receptors on syncytiotrophoblast involved in in utero transmission of HIV. RESULTS Syncytiotrophoblast was immunopositive for CD4 and CCR5 antibody with greater expression of CCR5 in HIV-positive versus HIV-negative groups (F1,159 = 6.979, P = 0.009) and normotensive versus pre-eclamptic groups (F1,159 = 8.803, P = 0.003). p24 was present in both placentae and umbilical cords of babies that were HIV-negative at 6 weeks. ICAM-2 immunostaining was observed in the syncytiotrophoblast across study groups and was significantly higher in the HIV-negative pre-eclamptic group (χ2 (3) = 45.3; P < 0.001). CONCLUSION Concurrent CD4 and CCR5 receptor expression demonstrates possible in utero viral entry routes across the placental barrier. ICAM-2 expression may influence HIV passage across the placenta or restoration of risk of pre-eclampsia in HAART-treated mothers. HIV was found in fetal circulation regardless of antiretroviral treatment. Further confirmatory ultrastructural and molecular work is warranted. TWEETABLE ABSTRACT CD4, CCR5 and ICAM-2 on syncytiotrophoblast may facilitate HIV infection of passage across the placenta.

Abstract
INTRODUCTION Lymphangiogenesis is the formation of new vessels from pre-existing lymphatic vessels. Data on lymphangiogenesis in the placenta of HIV-infected pre-eclamptics are sparse and the findings are conflicting. The aim of this novel study was to evaluate LYVE-1 immunoexpression in the placenta of HIV infected normotensive versus pre-eclamptic women. METHODS Placental tissue was obtained from normotensive and pre-eclamptic women stratified according to their HIV status. The pre-eclamptic group was divided into early (<34 weeks) and late (>34 weeks) onset. Immunohistochemistry utilized mouse anti-human LYVE-1 antibody and was morphometrically evaluated. RESULTS LYVE-1 immunostaining was localized within endothelium of the arterial supply and venous drainage of both conducting and exchange villi as well as within medial cells of arteries. LYVE-1 immunostained macrophage-like cells were observed within the fetal and maternal circulation. LYVE-1 immunoexpression was higher (p=0.0001) in HIV positive cohort, regardless of pregnancy and villous type. Irrespective of HIV status and pregnancy type, LYVE-1 immunoexpression was significantly elevated in the conducting compared to the exchange villi (p=0.01). LYVE-1 immunoexpression was higher in N and LOPE compared to EOPE groups for both conducting and exchange villi types respectively (p=0.0001 and p=0.006). There is a decrease of LYVE-1 expression in EOPE+ (conducting villi) and EOPE- (exchange villi) compared to N and LOPE subgroups. CONCLUSION This study provides a novel insight into an up-regulation of LYVE-1 expression in the fetal circulation of conducting and exchange villi of HIV-infected pre-eclamptics.

Abstract
OBJECTIVE To describe the incidence and obstetric and perinatal outcomes in primigravid Black South Africans with hypertensive disorders of pregnancy (HDP). METHOD All primigravidae who booked for antenatal care were followed up until hospital discharge. Relevant clinical and demographic data were collected in structured data forms. RESULTS A total of 5860 primigravidae delivered during the study period. Of these, 731 had an HDP, giving an incidence of 12.5%. The diagnosis of gestational hypertension was made in 6.7% of all primigravidae but was the commonest HDP subcategory (n = 394/731; 53.9%). On the other hand, mild to moderate preeclampsia or non-severe preeclampsia, severe preeclampsia, and eclampsia occurred in 222, 84, and 31 of the 5860 primigravidae, respectively. Therefore, preeclampsia-eclampsia syndrome occurred in 337/5860 or 5.75% of the study population. Severe preeclampsia occurred in 1.43% (84/5860) of the primigravidae. The rates of caesarean deliveries in women with preeclampsia were approximately 50%. There were no perinatal deaths in the gestational hypertension group, but the overall perinatal mortality rate in all preeclamptics was 5.9%, in comparison to 2.2% in all primigravidae. CONCLUSION Hypertensive disorders of pregnancy developed in 12.5% (n = 731/5860) of primigravidae seen over a one-year period. Gestational hypertension comprised the commonest subcategory of the HDP and there were no perinatal deaths in this group.

Abstract
OBJECTIVE To determine whether clinical and biochemical features associated with pre-eclampsia are significantly altered among women with HIV infection taking highly active antiretroviral therapy (HAART). METHODS A prospective observational cohort study was conducted between July 2013 and September 2014 at Prince Mshiyeni Memorial Hospital, Durban, South Africa. Women with and without pre-eclampsia and HIV infection were enrolled at booking and followed up until delivery. Specific demographic data, clinical features, laboratory indices, and complications were analyzed. RESULTS Of 193 participants, 98 had pre-eclampsia (45 [45.9%] with HIV infection). There were no significant differences in clinical features and laboratory indices among the study groups except for γ-glutamyl transferase levels, which were significantly higher among women with pre-eclampsia and HIV infection (26.9±40.9U/L) than among those with pre-eclampsia but no HIV infection (17.1±14.0U/L; P=0.001). Perinatal and maternal complications were similar, and there were no maternal deaths. CONCLUSION Clinical features, laboratory indices, and complications among women with pre-eclampsia and HIV infection taking HAART were similar to those among women with pre-eclampsia without HIV infection. Current guidelines remain appropriate; however, frequent hepatic function tests should be conducted.

Int J Gynaecol Obstet 2016; 134:299-303. [PMID: 27365290 DOI: 10.1016/j.ijgo.2016.03.014] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2015] [Revised: 02/21/2016] [Accepted: 05/19/2016] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To investigate the association between HIV, antiretroviral therapy (ART), and pregnancy-associated hypertension (PAH) in an HIV-endemic setting. METHODS A retrospective cohort study was undertaken of pregnant women for whom information was recorded between February 2006 and December 2012 in the Zambia Electronic Perinatal Record System, which captures data from 25 facilities in Lusaka, Zambia. PAH was defined as eclampsia, pre-eclampsia, hypertension, or elevated blood pressure (>140/80mm Hg) during delivery admission. Logistic regression estimated the odds of PAH among women by HIV serostatus, and by most recent CD4 T lymphocyte count and ART status among women with HIV infection. RESULTS Among 249 771 women included in the analysis, 5354 (2.1%) had PAH. Compared with women without HIV infection, women with HIV infection not receiving ART had lower odds of PAH (adjusted odds ratio [AOR] 0.86, 95% confidence interval 0.78-0.95), whereas those with HIV infection who had initiated ART had higher odds of PAH (AOR 1.15, 95% CI 1.01-1.32). No association was found between PAH and timing of ART initiation or CD4 lymphocyte count. CONCLUSION In a large African urban cohort, women with untreated HIV infection had the lowest odds of PAH. Treatment with ART could increase PAH risk beyond that of women without HIV infection and those with untreated infection.

Adams JW, Watts DH, Phelps BR. A systematic review of the effect of HIV infection and antiretroviral therapy on the risk of pre-eclampsia. Int J Gynaecol Obstet 2015; 133:17-21. [PMID: 26797203 DOI: 10.1016/j.ijgo.2015.08.007] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2015] [Revised: 07/24/2015] [Accepted: 11/27/2015] [Indexed: 01/01/2023]
Abstract
BACKGROUND The associations between HIV infection, antiretroviral therapy (ART), and pre-eclampsia are unclear. OBJECTIVES To summarize research and clarify the implications of HIV and ART on pre-eclampsia risk. SEARCH STRATEGY MedLine, PubMed, Web of Science, and the Cochrane Library were searched for studies published between 2003 and July 2014, using relevant keywords. SELECTION CRITERIA Full-text review was dependent on the inclusion of pre-eclampsia as an outcome and original data. DATA COLLECTION AND ANALYSIS Data for population, confounders, limitations, and measures of association were qualitatively assessed. MAIN RESULTS Among 550 records identified, 70 were screened, and 13 were included. Five of the nine studies comparing pre-eclampsia risk between women with and without HIV infection found no significant difference; only one found that women living with HIV were more likely to experience pre-eclampsia. Two studies found that women living with HIV who were receiving ART at conception were more likely to experience pre-eclampsia than were those not receiving ART at conception. Two studies reported that pre-eclampsia rates did not differ by ART regimen. CONCLUSIONS There is insufficient evidence to conclude that women living with HIV and receiving ART have a higher risk of pre-eclampsia than do women without HIV infection; further research is needed to assess the association between ART and pre-eclampsia.

Abstract
BACKGROUND There are data to suggest that infection with HIV or use of highly active antiretroviral therapy increases the risk of hypertensive disorders in pregnancy. This systematic review and meta-analysis aims to provide an overview of the research hitherto. METHODS A systematic review of EMBASE, PubMed, and The Cochrane Library databases was conducted to obtain articles about the association between HIV in pregnancy and/or HIV therapy and the risk of developing pregnancy-induced hypertension (PIH), pre-eclampsia, eclampsia, or Hemolysis Elevated Liver enzymes Low Platelet count syndrome. Quality of articles was evaluated with an adapted Cochrane Collaboration bias assessment tool. Relative risks (RRs) were pooled with a random-effects meta-analysis weighted by the inverse of their variance. RESULTS Of the 2136 articles screened, 28 studies were eligible for inclusion; 15 studies reported on the association with PIH, 16 on pre-eclampsia, 5 on eclampsia, and 3 articles on HIV therapy regimens. All articles had a high risk of bias, and between-study heterogeneity was considerable. Based on the meta-analysis, there does not seem to be an association between HIV and PIH [RR 1.26, 95% confidence interval (CI): 0.87 to 1.83, I = 78.6%], pre-eclampsia (RR 1.01, 95% CI: 0.87 to 1.18, I = 63.9%), or eclampsia (RR 1.61, 95% CI: 0.14 to 18.68, I = 97.0%). A meta-analysis of the association with HIV therapy and risk of hypertensive disorders in pregnancy could not be performed. CONCLUSIONS This meta-analysis shows no significant association between HIV positivity and PIH, pre-eclampsia, or eclampsia. However, the high risk of bias within most studies limits the strength of conclusions and well-designed studies are necessary to confirm or refute these findings.

Abstract
INTRODUCTION HIV makes a significant contribution to maternal mortality, and women living in sub-Saharan Africa are most affected. International commitments to eliminate preventable maternal mortality and reduce HIV-related deaths among pregnant and postpartum women by 50% will not be achieved without a better understanding of the links between HIV and poor maternal health outcomes and improved health services for the care of women living with HIV (WLWH) during pregnancy, childbirth, and postpartum. METHODS This article summarizes priorities for research and evaluation identified through consultation with 30 international researchers and policymakers with experience in maternal health and HIV in sub-Saharan Africa and a review of the published literature. RESULTS Priorities for improving the evidence about effective interventions to reduce maternal mortality and improve maternal health among WLWH include better quality data about causes of maternal death among WLWH, enhanced and harmonized program monitoring, and research and evaluation that contributes to improving: (1) clinical management of pregnant and postpartum WLWH, including assessment of the impact of expanded antiretroviral therapy on maternal mortality and morbidity, (2) integrated service delivery models, and (3) interventions to create an enabling social environment for women to begin and remain in care. CONCLUSIONS As the global community evaluates progress and prepares for new maternal mortality and HIV targets, addressing the needs of WLWH must be a priority now and after 2015. Research and evaluation on maternal health and HIV can increase collaboration on these 2 global priorities, strengthen political constituencies and communities of practice, and accelerate progress toward achievement of goals in both areas.

Abstract
OBJECTIVES To evaluate the incidence of and risk factors for hypertensive disorders in a cohort of HIV-infected pregnant women. METHODS Hypertensive disorders (HD) including preeclampsia/eclampsia (PE/E) and pregnancy induced hypertension, and risk factors were evaluated in a cohort of HIV-infected pregnant women from Latin America and the Caribbean enrolled between 2002 and 2009. Only pregnant women enrolled for the first time in the study and delivered at ≥20 weeks gestation were analyzed. RESULTS HD were diagnosed in 73 (4.8%, 95% CI: 3.8%-6.0%) of 1513 patients; 35 (47.9%) had PE/E. HD was significantly increased among women with a gestational age-adjusted body mass index (gBMI) ≥25 kg/m(2) (OR = 3.1; 95% CI: 1.9-5.0), hemoglobin (Hg) ≥11 g/dL at delivery (OR = 2.1; 95% CI: 1.2-3.6) and age ≥35 years (OR = 1.8; 95% CI: 1.1-3.2). PE/E was increased among women with a gBMI ≥25 kg/m(2) (OR = 3.0; 95% CI: 1.5-6.0) and Hg ≥11 g/dL at delivery (OR = 2.8; 95% CI: 1.2-6.5). A previous history of PE/E increased the risk of PE/E 6.7 fold (95% CI: 1.8-25.5). HAART before conception was associated with PE/E (OR = 2.3; 95% CI: 1.1-4.9). CONCLUSIONS HIV-infected women, with a previous history of PE/E, a gBMI ≥25 kg/m(2), Hg at delivery ≥11 g/dL and in use of HAART before conception are at an increased risk of developing PE/E during pregnancy.
