Contemporary prevalence and predictors of anxiety among patients living with HIVAIDS in Ghana

Objectives: To identify the prevalence and associated factors of anxiety in people living with HIV/AIDS in a tertiary centre in Ghana. Design: The study employed a cross-sectional design. Setting: The study was conducted in the outpatient HIV clinic of a tertiary hospital. Participants: Participants were adult PLWHA receiving OPD care, including those established on combined antiretroviral therapy (cART) and newer patients who were not on cART. Four hundred ninety-five participants aged ≥30 years were consecutively enrolled on the study. Interventions: Demographic and clinical data were collected using standard questionnaires and patient files. Anxiety was assessed using the Hospital Anxiety and Depression Scale (HADS). Multivariate logistic regression analysis was done to identify associated factors. Main outcome measure: Proportion of PLWHA who had HADS score of ≥8 Results: Overall prevalence of anxiety was 61.0% (95%CI: 56.6 ­ 65.3), with no significant difference between recently diagnosed (≤ 6 months, 64.3%) and those with established diagnoses (>6 months, 59.1%). Urban residence (aOR: 1.67, 95%CI: 1.12 ­ 2.51), alcohol use (aOR: 1.64, 95%CI: 1.13 ­ 2.38) and depression (aOR: 13.62, 95%CI: 7.91 ­ 23.45) were independently associated with anxiety. Conclusion: In this sample, 6 in 10 Ghanaian PLWHA had evidence of anxiety. Liaison with the national mental health service for more comprehensive and integrated care and further research into the mental health of PLWHA is recommended to reduce this high burden of anxiety

HIV-associated neurocognitive disorders

HIV infection is associated with disturbances in brain function referred to as HIV-associated neurocognitive disorders (HAND). This literature review outlines the recently revised diagnostic criteria for the range of HAND from the earliest to the more advanced stages: (i) asymptomatic neurocognitive impairment; (ii) mild neurocognitive disorder; and (iii) HIVassociated dementia. Relevant literature is also reviewed regarding the differential impact upon component cognitive domains known to be affected in HAND; which in turn should ideally be targeted during clinical and neuropsychological assessments: psychomotor and information processing speed; learning and memory; attention and working memory; speech and language; executive functioning and visuospatial functioning. A discussion outlining the neuropsychological tools used in the diagnostic screening of HAND is also included. The central mechanisms of HAND appear to revolve primarily around psychomotor slowing and cognitive control over mental operations; possibly reflecting the influence of disrupted fronto-striatal circuits on distributed neural networks critical to cognitive functions. The accurate assessment and diagnosis of HAND depends on meeting the need for statistically sound neuropsychological assessment techniques that may be used confidently in assessing South African populations; as well as the development of relevant norms for comparison of test performance data
