BackgroundThe use of neuroimaging modalities in psychiatry has been evaluated in several studies. The vast majority seem to suggest that neuroimaging may be overutilised in psychiatry. There is a significant constraint on availability and cost related to neuroimaging of patients at general state medical facilities. The routine use of computerised tomography (CT) scanning is thus questioned.MethodsA retrospective analysis was undertaken of all psychiatric inpatients who had CT scans performed from 01 January 2011 to 31 December 2012. Demographic data, mental state examination, physical examination findings, substance use and diagnosis upon admission were recorded. The relationship between these variables and CT scan findings was analysed.ResultsA total of 897 admissions were retrospectively analysed. One hundred and three patients had documented CT scan imaging. In total, 17 of the 23 patients with abnormal findings on CT scan were found to be psychotic (74.0%). The remaining 26.0% included depression and dementia. There was no statistically significant difference between the normal and abnormal CT scan groups with regard to gender, age, family history, substance use and physical examination. The majority (65.2%) had cerebral atrophy and/or cerebral calcifications. A smaller group of other documented findings was noted.ConclusionsSelective indications and clinical markers may be utilised in order to justify brain imaging studies rather than performing them routinely. That being true, a multicentre study with a larger sample size is indicated to further improve the statistical significance and assist in formulating a more concrete guideline for neuroimaging of psychiatric patients.

A systematic review and meta-analysis was conducted to synthesize data on HIV prevalence in individuals with first-episode psychosis (FEP) and to provide an overview of the association of HIV with clinical variables of FEP. Electronic databases were searched for quantitative studies published from January 1986 to November 2019. Meta-analyses were undertaken to calculate the pooled HIV/FEP proportion based on random effects modeling with inverse variance method. Seven HIV/FEP studies from sub-Sahara Africa (SSA) met inclusion criteria. The prevalence of HIV in FEP ranged from 24% to 40%, and FEP in people living with HIV (PLWHIV) ranged from 17% to 29%. The pooled proportion of HIV in FEP was 26% (95% confidence interval [CI], 10%-43%), with significant heterogeneity (n = 3, I 2 = 89%, p < 0.01), and of FEP in PLWHIV was 23% (95% CI, 15%-32%), without significant heterogeneity (n = 3, I 2 = 0%, p = 0.43). There are concerning levels of HIV and FEP comorbidity in SSA, necessitating an integrated health care service.

IntroductionSouth Africa (SA) has a high HIV prevalence and limited mental healthcare resources. Neuropsychiatric complications such as psychosis onset in people living with HIV (PLWHIV) remains poorly understood. The study aims to compare the socio-demographic, clinical, substance use, cognitive and trauma profile of PLWHIV presenting with first episode psychosis (FEP) to those with the condition but without HIV.Methods and analysisThis study will compare presentation, course, and outcome of a cohort of PLWHIV and FEP with a control group recruited over a 3-year period. We will prospectively test the hypothesis that the 2 groups are socio-demographically, clinically and cognitively distinct at illness presentation, with higher trauma burden and poorer outcomes in those with the dual burden of HIV and FEP. FEP participants, confirmed by a structured neuropsychiatric interview, will have their socio-demographic, psychosis, mood, motor, trauma and substance use variables assessed. A neuropsychological battery will be completed to assess cognition, while quality of life, psychotic symptoms and HIV markers will be measured at 3, 6 and 12 months.Ethics and disseminationThe study protocol has been reviewed and ethics approval obtained from the Biomedical Research Ethics Committee (BC 571/18) of the University of KwaZulu-Natal. The results from this investigation will be actively disseminated through peer-reviewed journal publications and conference presentations.

Background HIV, substance use and trauma are associated with more severe symptoms and poorer outcomes in psychosis. We aim to describe the profile of adults with first episode psychosis (FEP) and associations with substance use and trauma in a cohort of patients in a low resource, high HIV prevalence setting in South Africa. Methods We recruited all adult patients (18–45 years) presenting with FEP to five psychiatric units in the eThekwini Municipality, KwaZulu-Natal Province. Psychiatric diagnosis was made using the MINI. We used the PANSS for psychotic symptoms, WHO ASSIST for substance use and CTQ for early childhood trauma. HIV status was confirmed by ELISA. Results Sixty participants were recruited, mean age 26 years (SD 8, IQR 19–33), 68% (n=41) were male. Mean age at presentation was 24 and 31 years for males and females respectively, with males being significantly younger than females (p=0.0003). Duration of untreated psychosis (DUP) was 12.5 months (IQR 1–10.3 months). Lifetime tobacco, alcohol and cannabis use was reported at 57%, 55%, and 47% respectively. Substance use was more prevalent among males compared to females, p=0.10, 0.13 and 0.0001 for tobacco, alcohol and cannabis respectively. Lifetime cannabis use was associated with higher negative PANSS scores (mean score 32, SD 10) compared to non-users (mean score 17, SD 7), p=0.05. Sixty eight percent (n=41) reported any traumatic event. Sixty-two percent (n=37) experienced trauma before 18 years and 35% (n=21) reported traumatic experiences in adulthood. Individuals who reported trauma in adulthood had higher hostility scores in the PANSS compared to those who experienced no trauma in adulthood (p=0.05). Fifteen (25%) of the cohort was HIV infected. Females were more likely to be HIV infected (58% HIV infected females compared to 9.8% HIV infection in males, p=0.0001). Eleven of the 15 HIV infected patients had been on antiretroviral treatment prior to the psychosis onset and four were newly diagnosed at the time of psychosis presentation. Of the 11 individuals on antiretroviral treatment, 6 (45%) were virologically suppressed. There was no significant difference in PANSS scores by HIV status (p=0.5) and childhood trauma (p=0.5). Discussion The study found participants with FEP had a high prevalence of HIV, particularly in females, and high prevalence of tobacco, alcohol and cannabis use. This suggests that these individuals are particularly vulnerable to the triple burden of psychosis, substance use and HIV. In addition, they had long DUP suggesting delay in accessing treatment, which all serve as poorer prognostic indicators in an already overwhelmed health care setting. The high rates of trauma (more than half the sample reporting childhood trauma) is another major public health concern as trauma exposure has been associated with poorer physical and mental health outcomes. In this study the lack of association between childhood trauma and psychosis severity is inconsistent with literature and needs to be further explored. The association between adult exposure to trauma and increased hostility scores suggests the need to include psychological treatment strategies to address the trauma exposure to improve outcomes.
