Trauma and posttraumatic stress disorder in an urban Xhosa primary care population: prevalence,comorbidity, and service use patterns

Despite increased awareness of the prevalence and morbidity of psychiatric illnesses, relatively few studies have been undertaken in primary care settings in the African context. The authors determined the prevalence of trauma exposure and posttraumatic stress disorder (PTSD) in a South African township primary health care clinic and assessed associated demographic factors, comorbidity, service use, service satisfaction, and quality of life. Subjects were directly interviewed using translated, standardized instruments to assess variables described. Retrospective chart analysis assessed clinician case identification and psychotropic drug-prescribing habits. Of the 201 participants, 94% reported exposure to traumatic events (mean, 3.8). Trauma was associated with single status (p =.01), and PTSD was associated with poverty and single status (p =.04). Both sexes were equally likely to develop PTSD. PTSD (current; 19.9%), depression (37%), and somatization disorder (18.4%) were the most common diagnoses. Comorbidity with PTSD was high and included depression (75%, p <.01), somatization (35%, p <.01), and panic disorder (25%, p <.01). Levels of functional impairment were higher for subjects with PTSD, depression, and somatization than for those without (p <.05). PTSD comorbid with depression compounded impairment (p =.04). Levels of trauma, PTSD, and depression did not increase service use or dissatisfaction with services. Clinicians did not identify trauma (0%) or psychopathology (0%), and psychotropic medication was prescribed for only 1% of participants. In this population, trauma and PTSD were highly prevalent and associated with significant unidentified morbidity and comorbidity. Patients remain untreated for years in the current system of primary care consultations.     

Community attitudes toward and knowledge of mental illness in South Africa

Abstract. Background: Although recent advances in psychiatry have increased our understanding of psychiatric disorders,many people with chronic or severe psychiatric disorders may be unaware that effective treatment is available. It is possible that ignorance and stigma prevent such persons from seeking appropriate help, and that community attitudes and beliefs play a role in determining the help-seeking behaviour and successful treatment of the mentally ill. Nevertheless, there is little research on the attitudes of lay persons toward mental illness within the South African community. Objectives: The aim of this study was to investigate the knowledge and attitudes of the general South African public toward mental illness, specifically regarding the causes of illness and treatment options. Method: The study design employed a questionnaire survey. Structured interviews (n = 667) were conducted with members of the general public. One of eight vignettes, portraying depression, schizophrenia, panic disorder or substance abuse, with subtle or obvious symptoms, was presented to each respondent. Results: The main findings were that cases were most often conceptualised as stress-related or due to a lack of willpower rather than as medical disorders. Treatment advocated was more often to talk the problem over than to consult professional medical help. Psychotherapy was the preferred treatment option, particularly in vignettes where symptom presentation was subtle, and in cases of substance abuse. Conclusions: These data suggest that stigma and misinformation regarding mental illness exist, influencing preferred treatment modality and help-seeking behaviour. More work needs to be done to educate the public about the psychobiological underpinnings of psychiatric disorders and about the value of effective treatments. A better understanding of these disorders amongst the public would presumably lessen stigmatisation and encourage the use of currently available and effective interventions.     

Public perceptions on national health insurance: moving towards universal health coverage in South Africa.

BACKGROUND: Since 1994, considerable progress has been made in transforming the South African health care system, implementing programmes that improve the health of the population, and improving access to health care services. However, amid escalating health care costs disparities continue to exist between the public and private health sectors. The implementation of a national or social health insurance remains elusive despite three government-appointed committees on the matter. METHOD AND OBJECTIVE: This paper reports on the findings of a national probability household sample of the South African population, drawn as part of the 2005 HIV/AIDS national survey, to gauge public opinion on universal health care coverage. The perceptions of South Africans were assessed on selected health care affordability and financing issues. RESULTS: The majority support efforts to contain medicine costs and one-third are of the opinion that the country can provide everyone with all the needed health care and medical services. A large percentage of participants thought it more important to provide improved health care coverage even if it meant raising taxes, while a small percentage said it is better to hold down taxes despite lack of access to health care for some South Africans. Almost a quarter of participants were unable to comment on questions posed to them, indicating the need for improved public education and communication. CONCLUSION: The study provides important insights into public opinion on key policy issues. However, greater public awareness is needed to ensure an informed debate, while the design of a universal national health insurance scheme must take into account both the current context and public opinion.     

Detection of HIV type 1 gag-specific CD4(+) T cell responses in acutely infected infants

Multiple HIV-1-specific cytokine and proliferative responses by CD4(+) T cells have not been studied in acutely infected infants. Using an intracellular cytokine staining assay, 34 untreated clade C HIV-1-infected infants (2-102 days old) were assessed for IFN-gamma, 28/34 for IL-2, and 26/34 for TNF-alpha responses to all HIV-1 proteins. Responses were detected in 29%, 36%, and 15% of infants, respectively. Twelve of the original 34 infants were then studied longitudinally for 14 months to determine the effect of viral load on IFN-gamma Gag-specific responses: seven infants were treated for 1 year, stopped treatment, and resumed when CD4% was < 20 and five infants were treated only when the CD4% was <20. Following treatment cessation, there was an immediate increase in viral load followed by an increase in the magnitude of CD4(+) Gag-specific responses. Despite this, the majority of infants (54%) had to restart treatment by 24 months of age, indicating that the immune responses were antigen driven but not associated with protection. Among untreated infants HIV-specific CD4(+) responses were detected sporadically indicating a dysfunctional immune response in the face of constant exposure to high levels of viremia.     

Immunodominant HIV-1-specific HLA-B- and HLA-C-restricted CD8+ T cells do not differ in polyfunctionality

HIV-1 specific HLA-B-restricted CD8+ T cell responses differ from HLA-C-restricted responses in antiviral effectiveness. To investigate possible reasons for these differences, we characterized the frequency and polyfunctionality of immmunodominant HLA-B*57/B5801- and HLA-Cw*07-restricted CD8+ T cells occurring concurrently in nine study subjects assessing IFN-γ, TNF-α, IL-2, MIP-1β, and CD107a by flow cytometry and analyzed sequence variation in targeted epitopes. HLA-B*57/5801 and HLA-Cw*07 restricted CD8+ T cells did not differ significantly in polyfunctionality (p = 0.84). Possession of three or more functions correlated positively with CD4+ T cell counts (r = 0.85; p = 0.006) and monofunctional CD8+ T cells inversely correlated with CD4 cell counts (r = −0.79; p = 0.05). There were no differences in polyfunctionality of CD8+ T cells specific to wildtype versus mutated epitopes. These results suggest that loss of polyfunctionality and increase in monofunctional HIV-1-specific CD8+ T cells are associated with disease progression independent of restricting HLA allele. Furthermore, sequence variation does not appear to significantly impact CD8+ T cell polyfunctionality in chronic HIV-1 infection.     

Job stress,job satisfaction and stress‐related illnesses among South African educators

The aim of this study was to explore the relationship between self‐reported job stress and job satisfaction, and the prevalence of stress‐related illnesses and risk factors among educators. A cross‐sectional survey was conducted in a representative sample of 21,307 educators from public schools in South Africa. Results indicate that the prevalence of stress‐related illnesses were 15.6 per cent for hypertension, 9.1 per cent stomach ulcer, 4.5 per cent diabetes, 3.3 per cent minor mental distress, 3.1 per cent major mental distress and 3.5 per cent asthma. The study found considerably high stress levels among educators. Job stress and lack of job satisfaction were associated with most stress‐related illnesses (hypertension, heart disease, stomach ulcer, asthma, mental distress, tobacco and alcohol misuse). From three components of the demand‐control model, two, namely work stress from teaching methods and low peer support, were related to hypertension but not to heart disease. The components of the effort‐reward model of low socio‐economic status and lack of career advancement were both not related to heart disease, and only lack of career advancement was inversely related to hypertension. Most components assessed here of the demand‐control model (including stress with teaching methods and educational system and low peer support) and effort‐reward model (including job insecurity and lack of career advancement) were related to stomach ulcer and mental distress.

Selective serotonin reuptake inhibitors in the treatment of post-traumatic stress disorder: a meta-analysis of randomized controlled trials

Advances in the neurobiology of post-traumatic stress disorder (PTSD) and the availability of modern psychotropics have led to renewed interest in the pharmacotherapy of this disorder. In this paper we focus on trials of the selective serotonin reuptake inhibitors (SSRIs) in PTSD. Studies of the pharmacotherapy of PTSD were identified using methods developed by the Cochrane collaboration. Although a range of open trials of different SSRIs in PTSD show promise, there are few controlled pharmacotherapy studies in this disorder. Nevertheless, pharmacotherapy for PTSD appears to have reasonably robust effects, with odds ratios for responder status, defined as 'much improved' or 'very much improved' on the Clinical Global Impression Scale (CGI), on drug versus placebo varying from 2.2 to 5.6 in randomized controlled trials of different agents. The SSRIs appear both safe and effective for this indication. Additional research with these agents is necessary to clarify many questions, including predictors of response, duration of treatment, comparison with other agents, and integration with psychotherapy. In the interim, however, the SSRIs can be recommended as a first-line medication for the treatment of PTSD.     

The psychiatric sequelae of human rights violations: a challenge for primary health care

High rates of psychiatric morbidity have been documented in survivors of gross human rights abuses. Nevertheless, there has been relatively little focus on such patients in the context of primary care medicine. A sample of 134 survivors of gross human rights violations was assessed using a structured interview to determine exposure to violations and psychiatric status. In addition, psychiatric treatment history was probed with an open-ended interview. The study found that of the 95 of 134 (72%) participants who were assessed and found to have a current psychiatric diagnosis, only three were receiving treatment for such a disorder. Many subjects had presented to primary care clinics with somatic symptoms and had been prescribed benzodiazepines. Reasons for not reporting trauma or not seeking treatment included issues revolving around fear and mistrust, privacy and confidentiality, re-experiencing the trauma, and lack of awareness. Misdiagnosis and ineffective treatment of survivors of human rights abuses are likely to pose a significant drain on primary care resources. Accurate diagnosis and appropriate treatment are important challenges in primary care settings.     

Muscle dysmorphia: a South African sample

It has recently been suggested that muscle dysmorphia, a pathological preoccupation with muscularity, is a subtype of body dysmorphic disorder (BDD). There are, however, few studies of the phenomenology of this putative entity. Twenty-eight amateur competitive body builders in the Western Cape, South Africa, were studied using a structured diagnostic interview that incorporated demographic data, body-building activities and clinical questions focusing on muscle dysmorphia and BDD. There was a high rate of muscle dysmorphia in the sample (53.6%). Those with muscle dysmorphia were significantly more likely to have comorbid BDD based on preoccupations other than muscularity (33%). Use of the proposed diagnostic criteria for muscle dysmorphia indicated that this is a common and relevant entity. Its conceptualization as a subtype of BDD seems valid. The disorder deserves additional attention from both clinicians and researchers.
