RESUMEN

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. TRIAL REGISTRATION: Clinicaltrials.gov NCT04793217 . Retrospectively registered on 11 March 2021.

RESUMEN

AIMS: Mental disorders are common in people living with HIV (PLWH) but often remain untreated. This study aimed to explore the treatment gap for mental disorders in adults followed-up in antiretroviral therapy (ART) programmes in South Africa and disparities between ART programmes regarding the provision of mental health services. METHODS: We conducted a cohort study using ART programme data and linked pharmacy and hospitalisation data to examine the 12-month prevalence of treatment for mental disorders and factors associated with the rate of treatment for mental disorders among adults, aged 15-49 years, followed-up from 1 January 2012 to 31 December 2017 at one private care, one public tertiary care and two pubic primary care ART programmes in South Africa. We calculated the treatment gap for mental disorders as the discrepancy between the 12-month prevalence of mental disorders in PLWH (aged 15-49 years) in South Africa (estimated based on data from the Global Burden of Disease study) and the 12-month prevalence of treatment for mental disorders in ART programmes. We calculated adjusted rate ratios (aRRs) for factors associated with the treatment rate of mental disorders using Poisson regression. RESULTS: In total, 182 285 ART patients were followed-up over 405 153 person-years. In 2017, the estimated treatment gap for mental disorders was 40.5% (95% confidence interval [CI] 19.5-52.9) for patients followed-up in private care, 96.5% (95% CI 95.0-97.5) for patients followed-up in public primary care and 65.0% (95% CI 36.5-85.1) for patients followed-up in public tertiary care ART programmes. Rates of treatment with antidepressants, anxiolytics and antipsychotics were 17 (aRR 0.06, 95% CI 0.06-0.07), 50 (aRR 0.02, 95% CI 0.01-0.03) and 2.6 (aRR 0.39, 95% CI 0.35-0.43) times lower in public primary care programmes than in the private sector programmes. CONCLUSIONS: There is a large treatment gap for mental disorders in PLWH in South Africa and substantial disparities in access to mental health services between patients receiving ART in the public vs the private sector. In the public sector and especially in public primary care, PLWH with common mental disorders remain mostly untreated.

RESUMEN

This study aimed to identify alcohol use patterns associated with viral non-suppression among women living with HIV (WLWH) and the extent to which adherence mediated these relationships. Baseline data on covariates, alcohol consumption, ART adherence, and viral load were collected from 608 WLWH on ART living in the Western Cape, South Africa. We defined three consumption patterns: no/light drinking (drinking ≤ 1/week and ≤ 4 drinks/occasion), occasional heavy episodic drinking (HED) (drinking > 1 and ≤ 2/week and ≥ 5 drinks/occasion) and frequent HED (drinking ≥ 3 times/week and ≥ 5 drinks/occasion). In multivariable analyses, occasional HED (OR 3.07, 95% CI 1.78-5.30) and frequent HED (OR 7.11, 95% CI 4.24-11.92) were associated with suboptimal adherence. Frequent HED was associated with viral non-suppression (OR 2.08, 95% CI 1.30-3.28). Suboptimal adherence partially mediated the relationship between frequent HED and viral non-suppression. Findings suggest a direct relationship between frequency of HED and viral suppression. Given the mediating effects of adherence on this relationship, alcohol interventions should be tailored to frequency of HED while also addressing adherence.

RESUMEN

Driving ability can be diminished amongst people with HIV with associated neurocognitive impairment (NCI). We explore the relationship between HIV status, NCI and driving ability in professional truck drivers. Forty male professional drivers (20 HIV-positive; mean age = 39.20 ± 7.05) completed a neuropsychological test battery, two driving simulator tasks that assessed driving ability, and a driving history and habits questionnaire. A higher proportion of HIV-positive drivers exhibited impaired overall cognitive performance (p ≤ 0.001). Overall, drivers with NCI (defined as z ≤ 1.00) were more likely than those without NCI to crash (p = 0.002). There were no significant between-group (HIV-positive versus HIV-negative) differences with regard to self-reported on-road driving events. Professional drivers with NCI, as measured on a driving simulator, are at increased risk of making driving errors under high-risk conditions compared to their neurocognitively normal counterparts. These data should inform driver health management with regard to annual medical screening and surveillance.


RESUMEN: La capacidad de conducción puede verse disminuida entre las personas con VIH con deterioro neurocognitivo asociado (neurocognitive impairment, NCI). Exploramos la relación entre la situación frente al VIH, el NCI y la capacidad de conducción en conductores profesionales de camiones. Cuarenta conductores profesionales masculinos (20 seropositivos, edad media = 39.20 ± 7.05) completaron una batería de pruebas neuropsicológicas, dos tareas de simulador de conducción que evaluaron la capacidad de conducción y un cuestionario de hábitos y antecedentes de conducción. Una mayor proporción de conductores VIH positivos exhibió un desempeño cognitivo general deficiente (p ≤ 0.001). En general, los conductores con NCI (definido como z ≤ 1.00) tenían más probabilidades de chocar que aquellos sin NCI (p = 0.002). No hubo diferencias significativas entre los grupos (VIH positivo frente a VIH negativo) con respecto a los eventos autoinformados de conducción en carretera. Los conductores profesionales con NCI, según lo medido en un simulador de conducción, tienen un mayor riesgo de cometer errores de conducción en condiciones de alto riesgo en comparación con sus homólogos neurocognitivamente normales. Estos datos deberían informar a la gestión de la salud del conductor en lo que respecta a la vigilancia y los exámenes médicos anuales.

RESUMEN

Screening measures for depression developed in high-income countries have not always demonstrated strong psychometric properties in South Africa and with people living with HIV (PLWH). The present study explored the psychometric properties of the 16-item South African Depression Scale (SADS) comprised of idioms of distress specific to isiXhosa culture in PLWH. The SADS was administered to 137 Xhosa-speaking PLWH who met diagnostic criteria for major depressive disorder (MDD) together with the Hamilton Depression Scale (HAM-D) and the Center for Epidemiological Studies Depression Scale (CES-D). We conducted exploratory factor analysis, correlation, and reliability statistics. Four factors of the SADS emerged: Sadness, lethargy/burdened, anhedonia/withdrawal, and cognitive/somatic. All factors correlated significantly with the HAM-D and CES-D. Internal consistency of the overall measure was high (α = .89). The SADS promises to be a robust measure of depression in isiXhosa-speaking PLWH in South Africa likely due to the inclusion of local idioms of distress.

RESUMEN

Lay-counsellors in resource-limited settings convey critical HIV- and ART-information, and face challenges including limited training and variable application of counselling. This study explored lay-counsellors and Department of Health (DoH) perspectives on the utility of a multimedia adherence counselling program. Masivukeni, an mHealth application that provides scaffolding for delivering standardized ART counselling was used in a 3-year randomized control trail at two primary health care clinics in Cape Town, South Africa. In this programmatic and descriptive narrative report, we describe the application; lay-counsellors' response to open-ended questions regarding their experience with using Masivukeni; and perspectives of the City of Cape Town and Western Cape Government DoH, obtained through ongoing engagements and feedback sessions. Counsellors reported Masivukeni empowered them to provide high quality counselling. DoH indicated strong support for a future implementation study assessing feasibility for larger scale roll-out. Masivukeni has potential as a counselling tool in resource-limited settings.

RESUMEN

Screening for HIV-associated neurocognitive disorders (HAND) is important to improve clinical outcomes. We compared the diagnostic sensitivity and specificity of the mini-mental state examination, International HIV dementia scale (IHDS), Montreal cognitive assessment, Simioni symptom questionnaire and cognitive assessment tool-rapid version (CAT-rapid) to a gold standard neuropsychological battery. Antiretroviral-experienced participants from Cape Town, South Africa, and Baltimore, USA, were recruited. The sensitivity and specificity of the five tools, as well as those of the combined IHDS and CAT-rapid, were established using 2 × 2 contingency tables and ROC analysis. More than a third (65165) had symptomatic HAND. In detecting HIV-D, the CAT-Rapid had good sensitivity (94 %) and weak specificity (52 %) (cut-point ≤10), while the IHDS showed fair sensitivity (68 %) and good specificity (86 %) (cut-point ≤10). The combined IHDS and CAT-rapid showed excellent sensitivity and specificity for HIV-D at a cut-off score of ≤16 (out of 20; 89 and 82 %). No tool was adequate in screening for any HAND. The combination IHDS and CAT-rapid tool appears to be a good screener for HIV-D but is only fairly sensitive and poorly specific in screening for any HAND. Screening for milder forms of HAND continues to be a clinical challenge.

RESUMEN

BACKGROUND: The human immunodeficiency virus (HIV) can give rise to a spectrum of neuropsychological impairments known collectively as HIV-associated neurocognitive disorders (HAND). Although antiretroviral therapy (ART) has reduced the incidence of HIV dementia, the prevalence of milder forms of HAND has increased. It has been postulated that incomplete central nervous system (CNS) viral suppression or potential drug toxicity, both of which could be related to the CNS penetration effectiveness (CPE) of ART regimens, may contribute to this phenomenon. OBJECTIVE: This study compared cognitive outcomes in clade C-infected HIV patients in South Africa treated for 1 year with ART regimens with differing CPE scores. METHODS: We assessed 111 HIV-positive patients with varying levels of cognitive function at baseline (pre-ART) and then a year later. A neuropsychological battery was administered at both visits to derive global deficit scores. ART regimen data were collected at the follow-up visit. Some participants remained ART-naïve during this period, thus providing a non-treatment control group. RESULTS: Significantly more ART recipients maintained or improved cognitive function compared with patients not on ART (p=0.017). There was no significant difference in cognitive outcomes between higher and lower CPE regimen groups (p=0.473). CONCLUSIONS: ART preserves or improves cognition in HIV-infected patients after 1 year, irrespective of the regimen's CPE. South Africa's current low CPE-scored first-line regimen performed as well as higher CPE-scored regimens. These findings are reassuring for South Africa, but larger, longer-term studies would be more definitive.

RESUMEN

Mental disorders are highly prevalent across all health settings. Where they are co-morbid with other chronic physical disorders, a complex bidirectional relationship exists between them. While mental disorders may result in an increase in adverse healthrelated outcomes, they are amenable to cost-effective treatments. In resource-limited settings, many barriers to the detection and treatment of mental disorders exist. One approach to the effective targeting of the available resources is to utilize a "risk-flag" approach, wherein individuals at-risk of treatment failure are identified and routed into more intensive mental health screening and intervention. This paper discusses how lessons from HIV services may inform how to improve mental health care and integration in HIV settings, as well as in other chronic diseases.

RESUMEN

In this review, the neuropathogenesis of HIV dementia (HIV-D) is discussed in the context of the local epidemic. HIV-D continues to be prevalent in the era of highly active anti-retroviral therapy. HIV neuro-invasion into the central nervous system may result in the development of separate HIV genotypes in an individual through compartmentalisation. The blood brain barrier continues to limit penetration of anti-retroviral drugs into the cerebrospinal fluid. Individuals with active neuro-inflammation appear to respond well to HAART. In some cases low grade neuro-degeneration persists with consequent clinical deterioration. In South Africa, the emergence of a sub-epidemic of HIV-D is being driven by various factors, including the incomplete coverage of HAART to all who need it, the late stage presentation of people living with HIV/AIDS (PLWHA) and a co-occurring methamphetamine epidemic. Differences in viral subtype do not appear to confer protection against HIV-D. Implications for PLWHA who are at risk for HIV-D in South Africa are explored, with a view to providing suggestions for improving practice and research into this area.

RESUMEN

The relationship between mental illness and HIV/AIDS is complex and bidirectional. A significant amount of research has been performed in high-income countries but less is known about HIV and mental health in sub-Saharan Africa. The objectives of the review were to search the literature for quantitative studies conducted in sub-Saharan Africa on mental health and HIV and to critically evaluate and collate the studies in order to identify research needs and priorities. The databases Ovid; MEDLINE; PsycINFO and the Social Sciences Citation Index (SSCI) were searched for variations of search terms related to HIV/AIDS and mental health and studies limited to the populations of African countries. In addition; we hand-searched indexes of key journals and the databases of academic theses. We included 104 papers or research publications. The majority of these were published after 2005. The major topics covered were: mental-health-related HIV-risk behaviour; HIV in psychiatric populations; and mental illness in HIV-positive populations. The reported prevalence levels of mental illness among people living with HIV or AIDS (PLHIV) was high; with all but one study noting a prevalence of 19or higher. Neurocognitive changes in adults with HIV were also prevalent; with reported deficits of up to 99in symptomatic PLHIV and 33in non-symptomatic PLHIV. Research on HIV in relation to mental health is increasing; however; there is a need for good-quality prospective studies to investigate the bidirectional effects of mental illness and HIV on each other

RESUMEN

Background :The prevalence of infection with the Human Immuno-deficiency Virus (HIV) in South Africa is approaching 20of young adults. In severely mentally ill people; it is probably higher. Testing for infection is subject to stringent ethical principles. Undiagnosed HIV infection in people with severe mental illness increases costs and morbidity. Since effective treatments are available; it is imperative to diagnose HIV infection early in this high risk population. Methods : a literature review established the prevalence of HIV infection in in-patient populations with HIV infection. The pattern of testing for HIV over three years at a major psychiatric hospital was investigated. We surveyed public sector psychiatrists in the Western Cape to establish their attitudes to HIV in their patients. Results The HIV reported seroprevalence in psychiatric in-patients ranges from 0-59.3; with a mean of 10. Data show a clear trend towards an increase in prevalence: Pre 1996 the mean HIV seroprevalence was 7.4; while post 1996 the mean was 15. State psychiatrists in the Western Cape do not test routinely for HIV infection; mainly due to ethical constraints: 14.6of patients at Lentegeur Hospital were tested in 2006. Conclusions The high prevalence of HIV infection in South Africa; that is probably higher in patients with severe mental illness (most of whom are not competent to provide informed consent) and the availability of effective treatment; requires debate and a clear policy regarding testing for HIV infection to be implemented. We recommend a new approach to HIV testing in these patients

RESUMEN

OBJECTIVE: To describe the impact of services provided, during an admission,on unmet needs and correlates of unmet needs. METHOD: The study used a modified version of The Camberwell Assessment of Need (CAN) to assess the perceived needs of 100 patients on admission to a psychotherapy unit, Valkenberg Hospital, Cape Town. At discharge, the study documented the extent to which the patients had perceived services and interventions to be useful. RESULTS: The mean number of needs on admission was 8.6. At discharge, help received was highest for psychiatric needs. The services most often regarded as useful were organised group activities and therapies. Regression analysis suggests that a lower level of education and the presence of borderline personality traits contribute significantly to unmet need on discharge. CONCLUSION: The in-patient program is effective in meeting psychiatric needs, but less useful for addressing psycho-social needs. These needs may exacerbate psychiatric problems and should be managed more actively before, during and after an in-patient stay.
