Childhood sexual abuse (CSA) has been shown to be more prevalent among populations living with HIV. Antiretroviral therapy (ART) adherence is crucial for populations living with HIV as it significantly increases the likelihood of attaining and maintaining viral suppression. Previous findings on the association between CSA and ART adherence have been mixed. The current mixed-methods systematic review aimed to identify quantitative and qualitative studies from CINAHL, PsycInfo, PubMed, and Web of Science examining the relationship between CSA and ART adherence. Authors were also contacted if relevant data were unpublished. Studies had to be published from January 1, 2000 to April 1, 2019, written in English, and examined CSA as an exposure and ART adherence as an outcome. Four domains were combined: (1) childhood sexual abuse; (2) child; (3) antiretroviral; and (4) adherence. Eight quantitative and two qualitative studies were retained. The results showed that four quantitative studies found no association while the other four found factors such as timing of victimization, mental health and gender influenced the association between CSA and ART adherence. Themes emerging from the qualitative studies included use of ART evoking memories of CSA; CSA impacting mental health; and mental health treatment improving ART adherence. Mixed insights included the intricate links between CSA and ART adherence and the role of external factors on the relationship. ART adherence intervention programs may be needed for people who have experienced CSA. However, future studies are needed that will examine the association between CSA and ART adherence and include subgroup analyses.

AIDS (London, England) Apr 2017To summarize published evidence on drug interactions between hormonal contraceptives and antiretrovirals. (Review)
Review
OBJECTIVE
To summarize published evidence on drug interactions between hormonal contraceptives and antiretrovirals.
DESIGN
Systematic review of the published literature.
METHODS
We searched PubMed, POPLINE, and EMBASE for peer-reviewed publications of studies (in any language) from inception to 21 September 2015. We included studies of women using hormonal contraceptives and antiretrovirals concurrently. Outcomes of interest were effectiveness of either therapy, toxicity, or pharmacokinetics. We used standard abstraction forms to summarize and assess strengths and weaknesses.
RESULTS
Fifty reports from 46 studies were included. Most antiretrovirals whether used for therapy or prevention, have limited interactions with hormonal contraceptive methods, with the exception of efavirenz. Although depot medroxyprogesterone acetate is not affected, limited data on implants and combined oral contraceptive pills suggest that efavirenz-containing combination antiretroviral therapy may compromise contraceptive effectiveness of these methods. However, implants remain very effective despite such drug interactions. Antiretroviral plasma concentrations and effectiveness are generally not affected by hormonal contraceptives.
CONCLUSION
Women taking antiretrovirals, for treatment or prevention, should not be denied access to the full range of hormonal contraceptive options, but should be counseled on the expected rates of unplanned pregnancy associated with all contraceptive methods, in order to make their own informed choices.

Meta-Analysis
OBJECTIVES
This meta-analysis investigated the risk of congenital anomalies among infants of human immunodeficiency virus-infected pregnant women who were exposed to antiretroviral therapy (ART).
METHODS
Cohort studies, case-control studies, randomized controlled trials, and controlled clinical trials were reviewed by searching MEDLINE/PubMed, Embase, Web of Science, Scopus, AIDSLINE, CINAHL, Cochrane Library, and Google/Google Scholar. Methodological quality was assessed using the GRADE evaluation. A DerSimonian and Laird random-effects model was used. Subgroup analyses and meta-regression were used to investigate heterogeneity.
RESULTS
The electronic searches yielded 765 items. After quality assessment and grading, 30 studies were suitable for metaanalysis. In total, 1,461 congenital anomalies were found among 53,186 births. Children born to women receiving combined antiretroviral therapy (cART) had an approximately 10% higher risk of developing congenital anomalies (relative risk [RR], 1.09; 95% confidence interval [CI], 1.04 to 1.14). A subgroup analysis found no significant difference in the risk of congenital anomalies between cART and efavirenz users. However, zidovudine and protease inhibitor (RR, 1.09; 95% CI, 1.00 to 1.19) users were found to have a 10% increased risk of congenital anomalies, and integrase inhibitor users had a 60% increase in risk (RR, 1.61; 95% CI, 1.60 to 2.43). The subgroup results should be interpreted cautiously because of the moderate heterogeneity (I2 =58%).
CONCLUSIONS
The use of protease inhibitors, integrase inhibitors, zidovudine, and newer drugs should be carefully considered in pregnant women. Further studies are needed to address environmental, nutrition, and adherence factors related to ART. Establishing a congenital anomalies surveillance system is recommended.

Meta-Analysis Review
OBJECTIVE
Adolescent and young adult (AYA) populations (12-24 years) represent over 40% of new HIV infections globally. Adolescence is sometimes characterized by high-risk sexual behaviour and a lack of engagement with healthcare services that can affect adherence to antiretroviral therapy (ART). Despite adherence to ART being critical in controlling viral replication, maintaining health and reducing onward viral transmission, there are limited data on ART adherence amongst AYA globally. We undertook a systematic review and meta-analysis of published studies reporting adherence to ART for AYA living with HIV.
DESIGN AND METHODS
Searches included Embase, Medline and PsychINFO databases up to 14 August 2013. Eligible studies defined adequate adherence as at least 85% on self-report or undetectable blood plasma virus levels. A random effects meta-analysis was performed and heterogeneity examined using meta-regression.
RESULTS
We identified 50 eligible articles reporting data from 53 countries and 10,725 patients. Using a pooled analysis of all eligible studies, 62.3% [95% confidence interval (CI) 57.1-67.6; I:97.2%] of the AYA population were adherent to therapy. The lowest average ART adherence was in North America [53% (95% CI 46-59; I:91%)], Europe [62% (95% CI 51-73; I:97%)] and South America [63% (95% CI 47-77; I:85%] and, with higher levels in Africa [84% (95% CI 79-89; I:93%)] and Asia [84% (95% CI 77-91; I:0%].
CONCLUSION
Review of published literature from Africa and Asia indicate more than 70% of HIV-positive AYA populations receiving ART are adherent to therapy and lower rates of adherence were shown in Europe and North America at 50-60%. The global discrepancy is probably multifactorial reflecting differences between focused and generalised epidemics, access to healthcare and funding.

Review
Antiretroviral therapies (ARTs) have revolutionized the management of human immunodeficiency virus (HIV) infection, significantly improved patient outcomes, and reduced the mortality rate and incidence of acquired immunodeficiency syndrome (AIDS). However, despite the remarkable efficacy of ART, virologic failure remains a challenge in the long-term management of HIV-infected individuals. Virologic failure refers to the persistent detectable viral load in patients receiving ART, indicating an incomplete suppression of HIV replication. It can occur due to various factors, including poor medication adherence, drug resistance, suboptimal drug concentrations, drug interactions, and viral factors such as the emergence of drug-resistant strains. In recent years, extensive efforts have been made to understand and address virologic failure in order to optimize treatment outcomes. Strategies to prevent and manage virologic failure include improving treatment adherence through patient education, counselling, and supportive interventions. In addition, the regular monitoring of viral load and resistance testing enables the early detection of treatment failure and facilitates timely adjustments in ART regimens. Thus, the development of novel antiretroviral agents with improved potency, tolerability, and resistance profiles offers new options for patients experiencing virologic failure. However, new treatment options would also face virologic failure if not managed appropriately. A solution to virologic failure requires a comprehensive approach that combines individualized patient care, robust monitoring, and access to a range of antiretroviral drugs.

BACKGROUND
The mobilization of resources to prevent and treat human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) is unparalleled in the history of public health. The uptake of antiretroviral therapy (ART) has been rapid and unprecedented and made possible by the availability of funding - external and domestic. To justify continuous funding of ART in resource-scarce settings, a spate of cost-effectiveness studies has been undertaken in a number of countries. This paper is based on a systematic review of global studies on cost-effectiveness analysis of ART.
OBJECTIVES
The major objective was to review the existing literature on cost-effectiveness of ART to determine whether ART has been cost-effective (CE) in different settings.
METHODS
We searched PubMed and Google Scholar for articles published between 2008 and 2017. We included studies that measured costs as well as effectiveness of HIV treatment - specifically ART - using incremental cost-effectiveness ratio as one of the outcomes.
RESULTS
We identified 15 studies that met the search criteria for inclusion in the systematic review. The review confirms that ART programs have been CE across different settings, contexts, and strategies.
CONCLUSION
The review would be useful for countries that are straining to raise funds for the health sector, generally, and for AIDS prevention and control program, specifically. This would also be beneficial for carrying out similar studies, if necessary, and as an advocacy tool for garnering additional funding.

Review
OBJECTIVE
HIV (human immunodeficiency virus) infection remains a major public health challenge. Infected young people at any age are less likely to adhere to care in a timely manner and to maintain a suppressed VL. This review aims to identify factors associated with virologic failure and adherence to drug therapy in adolescents and young adults (10-24 years) living with HIV.
METHODS
Systematic review using the PubMed and Virtual Health Library databases and including articles published between 2009 and 2021. Data were analysed in six categories: individual factors, pharmacological/therapy-related aspects, factors related to HIV/acquired immunodeficiency syndrome (AIDS) infection, HIV/AIDS stigma, social support and health system/services. The study's protocol was registered on the PROSPERO platform (CRD42020167581).
RESULTS
A total of 19,819 articles were found in the initial search and 31 studies were included in this systematic review. Most studies were carried out on the African continent. Male sex, alcohol use, low education, adverse effects of medication, lack of social support, stigma related to HIV/AIDS, need for transportation to access the health service and forgetfulness were linked to poor adherence to therapy. Good adherence was achieved with sufficient nutrition, good social support, greater confidence in the use of therapy and fewer ART side effects. Low levels of CD4, alcohol use, substance abuse, low education, non-adherence to medication and forgetfulness were linked to virological failure.
CONCLUSION
Individual, social and structural factors constitute barriers to adherence to ART among adolescent and young adults. It is necessary to know the difficulties related to the use of therapy to work out specific strategies that create conditions to improve medication adherence and viral suppression, reducing the levels of virological failure in this population.

Review
The human immunodeficiency virus (HIV) is known to cause cardiovascular diseases in patients infected with HIV. The pathology ranges from atherosclerosis to cardiomyopathy. There are several factors that could possibly cause cardiovascular diseases in the HIV population, including malnutrition and vitamin deficiency (for example, thiamine, B12, and zinc deficiencies); a lifestyle including increased prevalence of alcoholism and illicit drug usage; viral infection; and medication combinations that could cause sudden cardiac deaths. Cardiovascular diseases contribute to major morbidity in these populations and could have a reflection on the global financial burden, thus emphasizing the importance of prevention strategies. In this article, we focused on several factors that contribute to coronary artery disease and other cardiovascular diseases. We found that HIV has direct and indirect effects on the development of coronary artery diseases; furthermore, antiretroviral therapy adds to the deleterious effects of HIV and increases the risk of cardiovascular diseases. We further assessed the causal relationships and associations to understand the research gaps. In conclusion, this paper acknowledges and summarizes the current management strategies and the need to develop future strategies focusing on the prevention of cardiovascular diseases and tailoring the regimens according to the patient's clinical and socio-economic background.

AIDS (London, England) Jul 2017There is inconsistent evidence that zidovudine use during pregnancy increases overall, cardiac, and male genital malformations. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
There is inconsistent evidence that zidovudine use during pregnancy increases overall, cardiac, and male genital malformations.
DESIGN
We conducted a systematic review and meta-analysis of zidovudine use and malformations and, using Bayesian methods, combined it with data from a cohort study of mother-infant pairs in the nationwide Medicaid Analytic eXtract (MAX).
METHODS
Using MAX data (2000-2010), we identified pregnant women with HIV treated with antiretroviral therapy (ART). Women with at least one zidovudine dispensing during the first trimester were compared to women receiving ART without zidovudine in the first trimester. Malformation outcomes were defined using diagnosis/procedure codes. To adjust for confounding, we performed 1 : 1 propensity score matching. Bayesian methods require specification of a prior, which we developed in the meta-analysis. Logistic regression models combined MAX data with the prior, estimating odds ratios (ORs) and 95% credible intervals.
RESULTS
Fourteen articles contributed information on overall malformations, seven on cardiac malformations, and five on male genital malformations. In MAX, matching led to a sample of 735 women each in the zidovudine and comparator groups. When comparing first trimester zidovudine use to other ART, the Bayesian procedure yielded OR estimates slightly above the null for overall [OR = 1.11, 95% credible interval (0.80-1.55)] and cardiac [OR = 1.30 (0.63-2.71)] malformations. There were no zidovudine-exposed cases of male genital malformations in MAX, but the meta-analysis yielded elevated OR estimates [OR = 2.57 (1.26-5.24)].
CONCLUSION
For most malformations, first-trimester zidovudine was not associated with increased risk. The potential increase in male genital malformations was small in absolute terms, and should be evaluated further.

Review
BACKGROUND
Few data are available on antiretroviral therapy (ART) response among HIV-2 infected patients. We conducted a systematic review on treatment outcomes among HIV-2 infected patients on ART, focusing on the immunological and virological responses in adults.
METHODS
Data were extracted from articles that were selected after screening of PubMed/MEDLINE up to November 2012 and abstracts of the 1996-2012 international conferences. Observational cohorts, clinical trials and program reports were eligible as long as they reported data on ART response (clinical, immunological or virological) among HIV-2 infected patients. The determinants investigated included patients' demographic characteristics, CD4 cell count at baseline and ART received.
RESULTS
Seventeen reports (involving 976 HIV-2 only and 454 HIV1&2 dually reactive patients) were included in the final review, and the analysis presented in this report are related to HIV-2 infected patients only. There was no randomized controlled trial and only two cohorts had enrolled more than 100 HIV-2 only infected patients. The median CD4 count at ART initiation was 165 cells/mm3, [IQR; 137-201] and the median age at ART initiation was 44 years (IQR: 42-48 years). Ten studies included 103 patients treated with three nucleoside reverse transcriptase inhibitors (NRTI). Protease inhibitor (PI) based regimens were reported by 16 studies. Before 2009, the most frequent PIs used were Nelfinavir and Indinavir, whereas it was Lopinavir/ritonavir thereafter. The immunological response at month-12 was reported in six studies and the mean CD4 cell count increase was +118 cells/μL (min-max: 45-200 cells/μL).
CONCLUSION
Overall, clinical and immuno-virologic outcomes in HIV-2 infected individuals treated with ART are suboptimal. There is a need of randomized controlled trials to improve the management and outcomes of people living with HIV-2 infection.
