Incidence and Persistence of Depression Among Women Living with and Without HIV in South Africa: A Longitudinal Study

Person-centred care for older adults living with HIV in sub-Saharan Africa

More than a fifth of people living with HIV in the US President's Emergency Plan for AIDS Relief-supported programmes are older individuals, defined as aged 50 years and older, yet optimal person-centred models of care for older adults with HIV in sub-Saharan Africa, including screening and treatment for geriatric syndromes and common comorbidities associated with ageing, remain undefined. This Position Paper explores the disproportionate burden of comorbidities and geriatric syndromes faced by older adults with HIV, with a special focus on women. We seek to motivate global interest in improving quality of life for older people with HIV by presenting available research and identifying research gaps for common geriatric syndromes, including frailty and cognitive decline, and multimorbidity among older people with HIV in sub-Saharan Africa. We share two successful models of holistic care for older people with HIV that are ongoing in Zimbabwe and Kenya. Lastly, we provide policy, research, and implementation considerations to best serve this growing population.

Mental health burden among females living with HIV and AIDS in sub-Saharan Africa: A systematic review

Mental health problems, particularly depression and anxiety, are common in women and young girls living with HIV/ AIDS particularly in low- and middle-income (LMICs) countries where women's vulnerability to psychiatric symptoms is heightened due to the prevalent intersectional stressors such as stigma and intimate partner violence. However, no synthesized evidence exists on the mental health burden of females living with HIV/AIDS (FLWHA) in Africa. This systematic review aimed to synthesize the current evidence on the mental health burden among FLWHA in sub-Saharan Africa. A systematic literature review of articles published from 2013-2023 was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). Five electronic databases; PubMed, MEDLINE with full text, Scopus, Academic Search Complete, and Health Source: Nursing Academic Edition were searched for articles published in English. Nineteen articles (15 quantitative, 3 qualitative, and 1 case study) from over 7 African countries met the inclusion criteria. The majority of the studies' quality was determined to be moderate. The prevalence of depression ranged from 5.9 to 61% and anxiety from 28.9 to 61%. Mental health burden was a logical outcome of HIV diagnosis. Predictors of mental health outcomes in the context of HIV/AIDS were identified as intimate partner violence (IPV), stigma, childhood traumas, sexual abuse, poverty, unemployment, and social isolation. Social support and resilience were identified as protective factors against mental illness in FLWHA. Mental illness had a deleterious effect on viral suppression rates among FLWHA, resulting in delayed initiation of antiretroviral therapy treatment and increased mortality but had no impact on immune reconstitution in the face of ART adherence. Given the high prevalence rates of depression and anxiety and their relationship with HIV progression, it is crucial that mental health care services are integrated into routine HIV care.

ImpACT+, a coping intervention to improve clinical outcomes for women living with HIV and sexual trauma in South Africa: study protocol for a randomized controlled trial

Background

Addressing sexual trauma in the context of HIV care is essential to improve clinical outcomes and mental health among women in South Africa. Women living with HIV (WLH) report disproportionately high levels of sexual trauma and have higher rates of posttraumatic stress disorder. Adherence to antiretroviral therapy (ART) may be difficult for traumatized women, as sexual trauma compounds the stress associated with managing HIV and is often comorbid with other mental health disorders, further compromising care engagement and adherence. ART initiation represents a unique window of opportunity for intervention to enhance motivation, increase care engagement, and address the negative effects of trauma on avoidant coping behaviors. Mental health interventions delivered by non-specialists in low- and middle-income countries have potential to treat depression, trauma, and effects of intimate partner violence among WLH. This study will examine the effectiveness of Improving AIDS Care after Trauma (ImpACT +), a task-shared, trauma-focused coping intervention, to promote viral suppression among WLH initiating ART in a South African clinic setting.

Methods

This study will be conducted in Khayelitsha, a peri-urban settlement situated near Cape Town, South Africa. Using a hybrid type 1 effectiveness-implementation design, we will randomize 350 WLH initiating ART to the ImpACT + experimental condition or the control condition (three weekly sessions of adapted problem-solving therapy) to examine the effectiveness of ImpACT + on viral suppression, ART adherence, and the degree to which mental health outcomes mediate intervention effects. ImpACT + participants will receive six once-a-week coping intervention sessions and six monthly maintenance sessions over the follow-up period. We will conduct mental health and bio-behavioral assessments at baseline, 4, 8, and 12 months, with care engagement data extracted from medical records. We will explore scalability using the Consolidated Framework for Implementation Research (CFIR).

Discussion

This trial is expected to yield important new information on psychologically informed intervention models that benefit the mental health and clinical outcomes of WLH with histories of sexual trauma. The proposed ImpACT + intervention, with its focus on building coping skills to address traumatic stress and engagement in HIV care and treatment, could have widespread impact on the health and wellbeing of individuals and communities in sub-Saharan Africa.

Psychiatric comorbidity and psychosocial stressors among people initiating HIV care in Cameroon

BACKGROUND

Psychiatric comorbidity, the presence of two or more mental health disorders, has been associated with suboptimal HIV treatment outcomes. Little is known about the prevalence of psychiatric comorbidity among people with HIV (PWH) in sub-Saharan Africa.

METHODS

We conducted interviews with PWH initiating HIV care in Cameroon between June 2019 and March 2020. Depression, anxiety, post-traumatic stress disorder (PTSD), and harmful drinking were dichotomized to represent those with and without symptoms of each. Psychiatric comorbidity was defined as having symptoms of two or more disorders assessed. Moderate or severe household hunger, high anticipatory HIV-related stigma, low social support, and high number of potentially traumatic events were hypothesized as correlates of psychiatric comorbidity. Bivariable log binomial regression models were used to estimate unadjusted associations between psychosocial stressors and psychiatric comorbidity.

RESULTS

Among 424 participants interviewed, the prevalence of psychiatric comorbidity was 16%. Among those with symptoms of at least one mental health or substance use disorder (n = 161), the prevalence of psychiatric comorbidity was 42%. The prevalence of psychiatric comorbidity was 33%, 67%, 76%, and 81% among those with symptoms of harmful drinking, depression, anxiety, and PTSD, respectively. Among individuals with symptoms of a mental health or substance use disorder, a high number of potentially traumatic events (prevalence ratio (PR) 1.71 [95% CI 1.21, 2.42]) and high anticipatory HIV-related stigma (PR 1.45 [95% CI 1.01, 2.09]) were associated with greater prevalence of psychiatric comorbidity.

CONCLUSION

Psychiatric comorbidity was common among this group of PWH in Cameroon. The effectiveness and implementation of transdiagnostic or multi-focus mental health treatment approaches in HIV care settings should be examined.

The benefits of psychosocial interventions for mental health in men who have sex with men living with HIV: a systematic review and meta-analysis

OBJECTIVE

Men who have sex with men (MSM) living with HIV are more likely to suffer from mental health problems. They should be given adequate attention to treat and improve their mental health disorders. This meta-analysis aimed to assess whether psychosocial interventions reliably improve psychological well-being among MSM living with HIV.

METHOD

Cochrane Library, EMBASE, PsycINFO, and PubMed were searched for psychosocial intervention randomized controlled trials evaluating mental health (e.g., depression, anxiety, self-efficacy). The effect size was pooled using the random-effects model, and continuous outcomes were reported using standardized mean difference (SMD) values .

RESULTS

A total of 12 studies including 1782 participants were included in the meta-analysis. Psychosocial interventions in contrast to control groups significantly reduced depression (SMD, - 0.28; 95% CI - 0.52 - - 0.03) at the follow-up assessment and improved quality of life (SMD 0.43, 95% CI 0.23-0.63) after treatment. Psychosocial interventions also had a significant effect on measures of self-efficacy (SMD 2.22, 95% CI 0.24-4.20), and this effect was sustained until long-term follow-up (SMD 0.55, 95% CI 0.02-1.08). Subgroup analyses revealed that improvements in depression were more significant when participants possessed higher education and treatment providers used cognitive behavioral therapy (CBT).

CONCLUSIONS

The findings of this study indicate that psychosocial interventions benefit the mental health of MSM living with HIV. It is necessary to conduct more research to explore characteristics that may affect treatment outcomes in the future.

Does HIV Stigma Predict Social Networks Over Time: A Latent Growth Curve Analysis

Persons living with HIV (PLWH) with socio-economic vulnerabilities are especially vulnerable to HIV stigma and adverse HIV outcomes. Stigma related to HIV may intersect with marginalized socio-economic conditions to negatively affect social networks. HIV stigma may limit the ability of individuals to sustain social relationships. This study examined the potential cross-sectional and longitudinal associations between HIV stigma and the quality and quantity of social networks for PLWH. PLWH (n = 1,082) who were experiencing housing, employment, and medical care-related difficulties were recruited to participate in a one-year navigation and system coordination intervention to improve housing stability and employment. Neither stigma reduction nor social networks were the main components of the intervention. A series of latent growth curves were estimated to assess the cross-sectional and longitudinal relationships among internalized and anticipated HIV stigma and social networks. Anticipated HIV stigma predicted social networks both cross-sectionally and longitudinally. Internalized HIV stigma predicted social networks cross-sectionally but not longitudinally in this population. These data support the HIV Stigma Framework and suggest that anticipated stigma seems to have a strong association with social networks. As anticipated stigma decreases over time, social network scores increase. Interventions to decrease anticipated HIV stigma as a mechanism of improving social networks warrants further investigation.

Parenting in matched pairs of women of color experiencing intimate partner violence and living with and without HIV

This study explored the associations between depression and parenting among women of color with low income levels who were exposed to intimate partner violence (IPV) and HIV. Participants were 60 Black, multiracial, and Hispanic/Latina mothers (Mage = 36.66, SD = 6.99) in the midsouth region of the United States. Mothers were recruited from community organizations and reported their experiences with IPV, HIV, depression, potentially traumatic events (PTE), parenting practices, and child maladaptive functioning. Participants living with HIV and experiencing recent IPV (i.e., cases) were matched on age, race, ethnicity, and educational attainment with mothers experiencing recent IPV (i.e., controls), for a matched sample of 30 pairs. Analyses were conducted to examine how HIV status moderated the associations between depressive symptoms and both negative and positive parenting while accounting for PTE, child maladaptive functioning, and IPV severity. The moderation model for negative parenting was significant, f2 = 0.58, but the moderation model for positive parenting was not, p = .346. Specifically, moderation was supported, B = 0.43, 95% CI [0.03, 0.83], t(53) = 2.17, p = .035, indicating that the association between depressive symptoms and negative parenting was moderated by HIV status. The findings highlight the added burden of a physical health condition on parenting practices. Given the role of negative parenting (i.e., inconsistency, poor monitoring, corporal punishment) in exacerbating poor health outcomes among children exposed to adversity, clinicians and researchers must develop family-based strategies to decrease these practices.

Prevalence and factors associated with common mental disorders in young people living with HIV in sub-Saharan Africa: a systematic review

INTRODUCTION

Common mental disorders (CMDs) particularly depression and anxiety, are highly comorbid with HIV also in young people living with HIV (YLWH). In sub-Saharan Africa (SSA) where most YLWH reside, there are limited summary data on CMDs among these youths, yet there are previous systematic reviews summarizing data on CMDs among adults living with HIV. We conducted a systematic literature review on the prevalence and correlates of CMDs among YLWH, aged 10 to 24 years, from SSA.

METHODS

We searched African Index Medicus, African Journals Online and five other electronic databases (from database inception up to 31 December 2020) for relevant studies published in English. The key search terms applied were as follows: "Depression OR Anxiety", "Young people", "HIV infections" and "sub-Saharan Africa".

RESULTS AND DISCUSSION

Out of 3989 articles, 31 studies were included in the review. The prevalence of CMDs in YLWH widely varied ranging between 16.0% and 40.8% for major depression, 4.4% and 52.6% for depressive symptoms and 2.2% and 25.0% for anxiety symptoms. Anxiety disorder was estimated at 45.6%. Four of the five included studies with a comparison group of HIV-negative young people reported significantly higher prevalence estimates of depressive disorders among YLWH. Several sociodemographic, psychosocial and HIV-related correlates of CMDs were reported but most lacked consensus across studies. Nevertheless, female sex, older age, fewer schooling years, HIV-positive status, bullying, sexual abuse, HIV-related stigma, social support and poor antiretroviral therapy adherence were frequently reported (in ≥2 studies) as significant correlates of depressive symptoms among YLWH. Higher social support was the only frequent significant correlate of anxiety symptoms.

CONCLUSIONS

The burden of CMDs among YLWH from SSA is substantial and appears to be significantly higher when compared with HIV-negative peers, particularly for depressive disorders. However, more comparative research is needed. Importantly, screening for CMDs at the youth HIV-clinics should be prioritized especially for YLWH at high risk of CMDs, to facilitate early management or referral for treatment. Furthermore, youth-friendly psychological interventions addressing CMDs in YLWH should urgently be piloted in SSA, incorporating contextual components that may directly or indirectly reduce symptoms of CMDs among YLWH, such as social support.

The Impact of Antiretroviral Therapy on Neurocognitive Outcomes Among People Living with HIV in Low- and Middle-Income Countries (LMICs): A Systematic Review

Low and middle-income countries (LMICs) are the epicenter of the HIV epidemic. The scale-up of antiretroviral therapy (ART) has reduced mortality, but HIV-associated neurocognitive impairment (HANI) remains prevalent, which impacts functional performance, medication adherence, and quality of life. We aimed to evaluate the effect of ART on neurocognitive outcomes among people living with HIV/AIDS in LMICs and to identify determinants of these outcomes. We searched electronic databases and reference lists for studies published between 1996 and 2019. Two reviewers screened the primary studies for inclusion and performed the critical appraisal. Results were synthesized using the 'Synthesis without meta-analysis' approach through simple vote counting. We identified 31 studies conducted across four regions (Africa, Asia, South America, and Eastern Europe). Nine studies were cross-sectional, 15 were prospective, and seven were randomized controlled trials. The majority of the articles showed improved neurocognitive performance with ART use but found no association with treatment duration, regimen, central penetrating effectiveness, and conventional biomarkers. Despite the lack of appropriate norms and not accounting for practice effect in most studies, the evidence suggests ART is useful in the treatment of HIV-associated neurocognitive impairment (HANI) but limited in addressing legacy effects, and peripheral, and central viral reservoirs. Improved early ART treatment programs, viral reservoir eradication strategies, and identification of novel biomarkers will be critical in efforts to minimize HIV-associated neurocognitive impairment.

Depression and Sexual Trauma Among Adolescent Girls and Young Women in HIV-Prevention Research in Tanzania

PURPOSE

Clinical trials are necessary to test HIV-prevention strategies among adolescent girls and young women in sub-Saharan Africa. Psychosocial risk factors that increase girls' and young women's vulnerability for HIV may also impact their experiences in clinical trials. A better understanding of psychosocial risks among girls and young women enrolled in HIV-prevention research is needed. This analysis explores depression and sexual trauma among adolescent girls and young women enrolled in a mock microbicide trial in Tanzania.

METHODS

We collected cross-sectional data from 135 HIV-negative adolescent girls and young women between 15 and 21 in Dar es Salaam, Tanzania enrolled in a mock microbicide trial. Depression, sexual behavior, and sexual trauma were measured. Sexual trauma and demographic variables were entered into a multivariate binomial logistic regression model predicting depression.

FINDINGS

Overall, 27% of participants had moderate-to-severe depression. The most commonly endorsed items were anhedonia (lack of interest/pleasure) and low mood, which were reported by 78% of participants. Thoughts of suicide or self-harm were endorsed by 17% of participants. Coerced/forced first sex was reported by 42% of participants. Participants reporting coerced/forced first sex had 3.16 times the likelihood of moderate-to-severe depression.

CONCLUSIONS

Depression and coerced/forced sex were common among participants in an HIV-prevention mock clinical trial in Tanzania. When enrolling adolescent girls and young women in HIV-prevention trials in sub-Saharan Africa, our research suggests the need for a trauma-informed approach, referrals for trauma and depression, and interventions that address the impact of depression and trauma on HIV prevention, clinical trial adherence, and clinical outcomes.

Studying the neuropsychological sequelae of SARS-CoV-2: lessons learned from 35 years of neuroHIV research

The virology of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and the human immune response to the virus are under vigorous investigation. There are now several reports describing neurological symptoms in individuals who develop coronavirus disease 2019 (COVID-19), the syndrome associated with SARS-CoV-2 infection. The prevalence, incidence, and clinical course of these symptoms will become clearer in the coming months and years through epidemiological studies. However, the long-term neurological and cognitive consequence of SARS-CoV-2 infection will remain conjectural for some time and will likely require the creation of cohort studies that include uninfected individuals. Considering the early evidence for neurological involvement in COVID-19 it may prove helpful to compare SARS-CoV-2 with another endemic and neurovirulent virus, human immunodeficiency virus-1 (HIV-1), when designing such cohort studies and when making predictions about neuropsychological outcomes. In this paper, similarities and differences between SARS-CoV-2 and HIV-1 are reviewed, including routes of neuroinvasion, putative mechanisms of neurovirulence, and factors involved in possible long-term neuropsychological sequelae. Application of the knowledge gained from over three decades of neuroHIV research is discussed, with a focus on alerting researchers and clinicians to the challenges in determining the cause of neurocognitive deficits among long-term survivors.

Technology-Delivered Psychotherapeutic Interventions in Improving Depressive Symptoms Among People with HIV/AIDS: A Systematic Review and Meta-analysis of Randomised Controlled Trials

With the increasing popularity of advanced technology, technology-delivered psychotherapeutic interventions (TPIs) may play a promising role in improving depressive symptoms among PLWHA. However, its effectiveness remains unclear. We aimed to synthesise the evidence of the effectiveness of TPIs in improving depressive symptoms of PLWHA using a meta-analytic approach. Seven databases were systematically searched for randomised controlled trials (RCTs) from the inception until August 14, 2018. Random-effects meta-analysis was adopted to assess effect size. Cochran's Q test and I² were used to investigate the problem of heterogeneity. Sensitivity, subgroup analyses and meta-regression were performed. Of the 43,048 records identified, 14 RCTs were included. The meta-analysis revealed a small effect on reducing depressive symptom scores (d = 0.23, 95% CI - 0.39 to - 0.06) after TPIs. Random-effects meta-regression showed that publication year was a significant moderator (p = 0.013), whereby the latest trials had larger effect size in reducing the depressive symptoms than earlier trials. Our review suggested a possible future approach of utilising TPIs by means of mobile applications and internet-based interventions for PLWHA to reduce their depressive symptoms. This review highlighted the essential key features in designing future TPIs. The overall low-quality evidence suggested the need to conduct further high-quality.

Global estimate of the prevalence of post-traumatic stress disorder among adults living with HIV: a systematic review and meta-analysis

OBJECTIVES

Although people living with HIV (PLWH) have been disproportionately affected by post-traumatic stress disorder (PTSD), the global prevalence of PTSD among PLWH is unknown. This study aimed to systematically review the prevalence of PTSD among PLWH worldwide and explore variation in prevalence across sociodemographic and methodological factors.

DESIGN

A meta-analysis using a random-effects model was conducted to pool the prevalence estimated from individual studies, and subgroup analyses were used to analyse heterogeneities.

SETTING, PARTICIPANTS AND MEASURES

Observational studies providing PTSD prevalence data in an adult HIV population were searched from January 2000 to November 2019. Measurements were not restricted, although the definition of PTSD had to align with the Diagnostic and Statistical Manual of Mental Disorders or the International Classification of Diseases diagnostic criteria.

RESULTS

A total of 38 articles were included among 2406 records identified initially. The estimated global prevalence of PTSD in PLWH was 28% (95% CI 24% to 33%). Significant heterogeneity was detected in the proportion of PLWH who reported PTSD across studies, which was partially explained by geographic area, population group, measurement and sampling method (p<0.05).

CONCLUSION

PTSD among PLWH is common worldwide. This review highlights that PTSD should be routinely screened for and that more effective prevention strategies and treatment packages targeting PTSD are needed in PLWH.

Psychological and Physical Intimate Partner Violence and Maternal Depressive Symptoms during the Pre- and Post-Partum Period among Women Living with HIV in rural South Africa

PURPOSE

Women in South Africa also have high rates of depression and intimate partner violence, and they often co-occur. Women living with HIV who experience IPV are particularly likely to experience elevated levels of depressive symptoms and such symptoms are more likely to persist. Although the association between IPV and depression has been examined extensively, the role of depression on IPV has not. Therefore, this study examined the bidirectional association between intimate partner violence (IPV) and depression in South Africa (SA).

METHOD

Participants were N=699 pregnant women with HIV in rural SA who completed measures of depressive symptoms and IPV at baseline (M=17.52±5.77 weeks of pregnancy), 32 weeks antenatally, and 6- and 12-months postnatally.

RESULTS

Depressive symptoms were linked to increased psychological IPV from baseline to 32-weeks, and from 32-weeks to 6-months. However, from 6-months to 12-months, depressive symptoms were associated with decreased psychological IPV. Psychological IPV was linked to depressive symptoms from baseline to 32-weeks. Depressive symptoms were associated with physical IPV from 32-weeks to 6-months, and 6-months to 12-months. Physical IPV was associated with increased depressive symptoms from baseline to 32-weeks, and from 32-weeks to 6-months.

CONCLUSIONS

Findings merit replication, as there may be measurement differences of psychological IPV in SA. However, targeting depressive symptoms and IPV concurrently in prevention and intervention programs may help optimize maternal and child outcomes in the context of prevention of mother-to-child transmission of HIV.

Maternal HIV does not affect resiliency among uninfected/HIV exposed South African children from birth to 5 years of age

OBJECTIVE

Examine resiliency among a South African population cohort of children of mothers living with HIV (MLH) and mothers without HIV (MWOH) in low-income townships over the first 5 years of life.

DESIGN

A cluster randomized controlled intervention trial evaluating child resiliency and the effects of home visiting in township neighborhoods from pregnancy through 5 years postbirth.

METHODS

The population of pregnant women in 24 matched neighborhoods were recruited and randomized by neighborhood to a standard care condition (n = 594) or a paraprofessional home visiting intervention condition (n = 644). Mothers and children were assessed at 2 weeks, 6, 18, 36, and 60 months postbirth (92-84% follow-up; 10.2% mortality). Resilient children were identified based on consistently meeting global standards for growth, cognitive functioning, and behavior. Maternal HIV status (n = 354 MLH; n = 723 mothers without HIV MWOH), intervention condition, maternal risks, caretaking, sociodemographic characteristics, and neighborhood were examined as predictors of child resiliency over time using analysis of variance, chi-square analyses, and Fisher's exact tests, where appropriate.

RESULTS

None of HIV-seropositive children (n = 17) were resilient; 19% of 345 HIV-exposed but uninfected children of MLH were resilient, a rate very similar to the 16% among MWOH. Resiliency was significantly associated with lower income, food security, not having a live-in partner, and the absence of maternal risk (i.e., not being depressed, using alcohol, or being a victim of intimate partner violence). Being randomized to a home visiting intervention, maternal breastfeeding for at least 3 months and attending a preschool crèche were also unrelated to resiliency. Although matched pairs of neighborhoods had similar rates of resilient children, resiliency varied significantly by neighborhood with rates ranging from 9.5 to 27%.

CONCLUSION

We set a new standard to define resiliency, as consistently recommended by theoreticians. Although seropositive children are not resilient, uninfected children of MLH are as resilient as their peers of MWOH. Typical protective factors (e.g., home visiting, breastfeeding, preschool) were unrelated to resiliency over the first 5 years of life.

Childhood trauma interacts with ApoE to influence neurocognitive function in women living with HIV

HIV-associated neurocognitive disorder (HAND) describes a spectrum of behavioural, motor and cognitive disturbances that can occur secondary to HIV infection. Less severe forms of the disorder persist despite advances in antiretroviral medication efficacy and availability. Childhood trauma (CT) may predispose individuals to developing HAND. As genetic variation in human apolipoprotein E (ApoE) has been implicated in cognitive decline and may mediate the development of long-term health outcomes following CT, we investigated the influence of ApoE and CT on cognitive function in the context of HIV. One hundred twenty-eight HIV-positive Xhosa women completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF) as well as the HIV Neurobehavioural Research Center neurocognitive test battery. rs7412 and rs429358 were genotyped using KASP assays, and this data was used to determine the ApoE isoform. Baseline differences in demographic and clinical variables according to CT exposure were calculated. Analysis of covariance was used to assess the contributions of CT and ApoE variants, as well as their interaction, to cognitive function. Eighty-eight participants reported experiencing CT. The rs7412 C allele protected against the harmful effect of CT on motor scores using an additive model. The interaction of ApoE ε4 and CT was associated with worse attention/working memory scores. ApoE ε4, alone and in combination with CT, is associated with poorer cognitive function. Further research into this gene-environment interaction may assist in identifying at-risk individuals for targeted interventions.

Counseling for improving adherence to antiretroviral treatment: a systematic review

One-on-one counseling can be an effective strategy to improve patient adherence to HIV treatment. The aim of this systematic review is to examine articles with one-on-one counseling-based interventions, review their components and effectiveness in improving ART adherence. A systematic review, using the following criteria was performed: (i) experimental studies; (ii) published in Spanish, English or Portuguese; (iii) with interventions consisting primarily of counseling; (iv) adherence as the main outcome; (v) published between 2005 and 2016; (vi) targeted 18 to 60 year old, independent of gender or sexual identity. The author reviewed bibliographic databases. Articles were analyzed according to the type of study, type of intervention, period of intervention, theoretical basis for intervention, time used in each counseling session and its outcomes. A total of 1790 records were identified. Nine studies were selected for the review, these applied different types of individual counseling interventions and were guided by different theoretical frameworks. Counseling was applied lasting between 4 to 18 months and these were supervised through three to six sessions over the study period. Individual counseling sessions lasted from 7.5 to 90 minutes (Me. 37.5). Six studies demonstrated significant improvement in treatment. Counseling is effective in improving adherence to ART, but methods vary. Face-to-face and computer counseling showed efficacy in improving the adherence, but not the telephone counseling. More evidence that can determine a basic counseling model without losing the individualized intervention for people with HIV is required.
