Neurocognitive impairment among HIV-positive individuals in Botswana: a pilot study

BackgroundThe primary objective of this study was to determine the prevalence of neurocognitive impairment among HIV-positive individuals in Botswana, using the International HIV Dementia Scale (IHDS). We also compared performance on the IHDS with performance on tests of verbal learning/memory and processing speed, and investigated the association between performance on the IHDS and such variables as depression, age, level of education and CD4 count.MethodsWe conducted a cross-sectional study of 120 HIV-positive individuals randomly selected from an outpatient HIV clinic in Gaborone, Botswana. Patients provided a detailed clinical history and underwent neuropsychological testing; measures of depression, daily activities and subjective cognitive complaints were recorded.ResultsDespite the fact that 97.5% of subjects were receiving highly active antiretroviral therapy (HAART), 38% met criteria for dementia on the IHDS, and 24% were diagnosed with major depressive disorder. There was a significant association between neurocognitive impairment as measured by the IHDS and performance on the other two cognitive measures of verbal learning/memory and processing speed. Level of education significantly affected performance on all three cognitive measures, and age affected processing speed and performance on the IHDS. Depression and current CD4 count did not affect performance on any of the cognitive measures.ConclusionsThe prevalence of neurocognitive impairment in HIV-positive individuals in Botswana is higher than expected, especially since almost all of the subjects in this study were prescribed HAART. This suggests the need to reconsider the timing of introduction of antiretroviral therapy in developing countries where HAART is generally not administered until the CD4 cell count has dropped to 200/mm3 or below. The contribution of other factors should also be considered, such as poor central nervous system penetration of some antiretrovirals, drug resistance, potential neurotoxicity, and co-morbidities. Memory impairment and poor judgment may be underlying causes for behaviours that contribute to the spread of HIV and to poor adherence. It is important to identify these neurobehavioural complications of HIV so that effective treatments can be developed.

Depression among HIV-positive individuals in Botswana: a behavioral surveillance.

This study examined incidence of depression in HIV-positive individuals in Botswana. One hundred and twenty HIV-positive individuals were administered a measure of daily activities and two measures of depression. Twenty four to 38% were diagnosed with depression, suicidal ideation ranged from 9 to 12%, with a positive correlation between scores on the two depression measures. Depression was associated with greater impairment in activities of daily living, especially the ability to take medication. These instruments can diagnose depression in persons living with HIV in developing countries, which will help to target those at risk for poor adherence, and will enable better allocation of limited resources.

Rapid psychosocial function screening test identified treatment failure in HIV+ African youth

Abstract Psychosocial dysfunction in older children and adolescents is common and may lead to nonadherence to HIV treatments. Poor adherence leads to HIV treatment failure and the development of resistant virus. In resource-limited settings where treatment options are typically limited to only one or two available lines of therapy, identification of individuals at highest risk of failure before failure occurs is of critical importance. Rapid screening tools for psychosocial dysfunction may allow for identification of those children and adolescents who are most likely to benefit from limited psychosocial support services targeted at preventing HIV treatment failure. The Pediatric Symptom Checklist (PSC) is used in high resource settings for rapid identification of at-risk youth. In 692 HIV-infected treated children (ages of 8–< 17 years) in Botswana, having a high score on the PSC was associated with having virologic failure (OR 1.7, 95% CI: 1.1–2.6). The PSC may be a useful screening tool in pediatric HIV.

Neurobehavioral Effects in HIV-Positive Individuals Receiving Highly Active Antiretroviral Therapy (HAART) in Gaborone, Botswana

Objective To explore the prevalence and features of HIV-associated neurocognitive disorders (HANDS) in Botswana, a sub-Saharan country at the center of the HIV epidemic. Design and Methods A cross sectional study of 60 HIV-positive individuals, all receiving highly active antiretroviral therapy (HAART), and 80 demographically matched HIV-seronegative control subjects. We administered a comprehensive neuropsychological test battery and structured psychiatric interview. The lowest 10th percentile of results achieved by control subjects was used to define the lower limit of normal performance on cognitive measures. Subjects who scored abnormal on three or more measures were classified as cognitively impaired. To determine the clinical significance of any cognitive impairment, we assessed medication adherence, employment, and independence in activities of daily living (ADL). Results HIV+ subjects were impaired for all cognitive-motor ability areas compared with matched, uninfected control subjects. Thirty seven percent of HIV+ patients met criteria for cognitive impairment. Conclusion These findings indicate that neurocognitive impairment is likely to be an important feature of HIV infection in resource-limited countries; underscoring the need to develop effective treatments for subjects with, or at risk of developing, cognitive impairment.

Validation of the Pediatric Symptom Checklist in HIV-infected Batswana

Objective: To determine the validity of the Pediatric Symptom Checklist (PSC), a brief measure of psychosocial health, for screening HIV+ Batswana children. Method: Setswana versions of the parent and child PSC were administered to 509 HIV+ Batswana children (age 8–16) and their parents/guardians. Test properties were evaluated and cut-off scores were derived using receiver operating characteristic curve analysis. Scores on the parent-completed PSC and the child-completed PSC-Y were compared to parental and clinic staff reports of concern about the childs psychosocial health and to scores on the Childrens Depression Inventory and the Revised Childrens Manifest Anxiety Scale. Results: The Setswana PSC has high internal consistency (Cronbachs alpha 0.87 for the parent-completed version). Comparing PSC scores to parental reports of concern and child-reported depression symptoms, a cut-off score of 20 on the PSC and PSC-Y maximised the sensitivity and specificity. Conclusions: The PSC performed well in Setswana-speaking children and is a promising screening tool for paediatric psychosocial problems in busy clinical settings. Screening with the PSC may allow for early detection and treatment of psychosocial problems. This is likely to be of particular value for HIV+ children for whom HIV treatment non-adherence may result from untreated psychosocial dysfunction.

Sexual abuse and violence among adolescent girls in Botswana: a mental health perspective

The presence of sexual abuse among societies in Botswana is a phenomenon whose occurrence is usually denied albeit the police report on it and legal frameworks have been established to combat it. Several factors influence the concealment of sexual abuse among adolescent girls, which includes cultural factors and social status of the perpetrators. This paper espouses the concept of sexual abuse among adolescent girls, the existence of the problem, its magnitude, the factors that increase vulnerability to violence and abuse, and how these factors intersect with HIV and AIDS. Two case studies using a discovery method were used to explore the phenomenon under the study. The findings of the study indicated that sexual abuse and violence have profound mental health consequences including guilt, anxiety, depression and anger. Future research is suggested to explore this problem on a wider scale and develop interventions that can assist victims and perpetrators to cope with the situation.

Training tomorrow’s global health leaders: applying a transtheoretical model to identify behavior change stages within an intervention for health leadership development

Training health professionals in leadership and management skills is a key component of health systems strengthening in low-resource settings. The importance of evaluating the effectiveness of these programs has received increased attention over the past several years, although such evaluations continue to pose significant challenges. This article presents evaluation data from the pilot year of the Afya Bora Fellowship, an African-based training program to increase the leadership capacity of health professionals. Firstly, we describe the goals of the Afya Bora Fellowship. Then, we present an adaptation of the transtheoretical model for behavior change called the Health Leadership Development Model, as an analytical lens to identify and describe evidence of individual leadership behavior change among training participants during and shortly after the pilot year of the program. The Health Leadership Development Model includes the following: pre-contemplation (status quo), contemplation (testing and internalizing leadership), preparation – (moving toward leadership), action (leadership in action), and maintenance (effecting organizational change). We used data from surveys, in-depth interviews, journal entries and course evaluations as data points to populate the Health Leadership Development Model. In the short term, fellows demonstrated increased leadership development during and shortly after the intervention and reflected the contemplation, preparation and action stages of the Health Leadership Development Model. However, expanded interventions and/or additional time may be needed to support behavior change toward the maintenance stages. We conclude that the Health Leadership Development Model is useful for informing health leadership training design and evaluation to contribute to sustainable health organizational change.

Depression in HIV-positive women in Gaborone Botswana.

This cross-sectional study measured prevalence of depression and suicide ideation in 62 randomly selected HIV-positive (HIV+) women in Botswana, a resource-limited country at the center of the HIV/AIDS epidemic. They were administered two screening measures of depression, an inventory of activities of daily living (ADL), and subjective questionnaire of cognitive functioning. Results show that the two screening measures are useful for detecting depression in women infected with HIV in resource-limited countries. Diagnosis of depression is of great importance, not only clinically, but also to ensure judicious allocation of scarce medical resources in the regions worst affected by the HIV epidemic.

Voices from the frontlines: the epidemics of HIV/AIDS and violence among women and girls

The papers in this special issue focus on the topic of violence against women. This group of scholarly works explores theoretical issues, context and health care interventions pertaining to violence in women’s lives. In conjunction with this special issue, this editorial provides a synopsis of presentations and discussions about the topic of the intersections of gender-based violence, HIV and the girl child that took place in July 2008 as part of the 17th conference of International Council of Women’s Health Issues (ICOWHI) held in Gaborone, Botswana, focusing on the Girl Child. ICOWHI, in conjunction with the University of Botswana, Centre for the Study of HIV and AIDS (CSHA) sponsored a one day preconference on “Gender-based violence and HIV Risk among Adolescent Girls.” A diverse interdisciplinary group of scholars from around the world closely examined these interconnected epidemics in a rich day long discussion. The aim of the preconference as well as the articles in this special issue is to build scholarship and inform practice of cultural and contextual factors as they pertain to violence in the lives of women and girls in order to promote their health, safety and well-being globally.

Emotional Violence Among Women in Intimate Relationships in Botswana

A Heideggerian hermeneutic phenomenological approach was used to investigate the lived experience of women in Botswana who had experienced emotional abuse in intimate relationships. Hermeneutic phenomenology is concerned with the human experience as it is lived. Ten educated Botswana women who had formal employment and have been in intimate relationships for longer than ten years, narrated their life experiences with abusive men. Extensive interviews took place over a six month period. Sociocultural practices in Botswana emerged as salient factors that contribute to emotional abuse and predispose women to mental illness. Entwined in these cultural practices are issues of age, ethnicity, payment of lobola (bride price), financial standing, change of name, and relocation to the mans residence. Education and employment seem to worsen the abuse. Depression and anxiety are common results of abuse. Understanding how the sociocultural factors perpetuate abuse can assist nurses in the way they provide health care services to women.
