Depression associated with antiretroviral drug therapy in HIV: case report and overview

Depression is the main psychiatric symptom in patients living with HIV. Genetic predisposition, stress from disease as well as the antiretroviral therapy itself are discussed as pathogenic factors. We report a 35-year-old HIV-positive man suffering from bipolar disorder who developed major depression shortly after commercing combination antiretroviral therapy (cART) on three occasions. The first two times the patient ceased therapy autonomously, and the depression disappeared completely. The close connection between cART and major depression in the present case supports the depression-inducing potential of cART. Additionally, we present an overview of literature.

[Emotional status, cognitive performance and quality of life in HIV-infected patients. Results of an exploratory study]

BACKGROUND

Due to the change of HIV disease from an acute life-threatening disease to a chronic infection, it is more psychosocial rather than therapeutic aspects that have become of interest in scientific investigations. The purpose of this exploratory study was to evaluate emotional distress, health-related quality of life (HRQoL) and cognitive performance. The diagnosis of HIV was considered a life event that may lead to post-traumatic stress syndrome.

METHOD

We recruited 37 HIV-positive outpatients and assessed the frequency of depressive (BDI) and post-traumatic stress symptoms (PTSS) due to the diagnosis of HIV (IES), HRQoL (SF-36) and cognitive performance (SKT). Further, the new diagnostic concept of adjustment disorder as a stress response syndrome according to Maercker was considered.

RESULTS

Of the 37 Patients, 67.6% (n=25) of the sample had a post-traumatic stress syndrome. The HIV-related PTSS was considered adjustment disorder using the concept proposed by Maercker. Fourteen patients (37.8%) suffered from a depressive syndrome, and 27% (n=10) showed cognitive deficits (minimal: n=8; mild: n=1; moderate: n =1). HIV-positive patients with PTSS had significantly unfavourable values in the SF-36 domains general health (p=0.003), vitality (p=0.007), social functioning (p=0.000), role-emotional (p=0.016) and mental health (p=0.000).

CONCLUSION

HIV-infected patients may face a major risk of HIV-related PTSS in the sense of adjustment disorder according to Maercker, depression and cognitive dysfunction. The presence of emotional distress is associated with impairments in quality of life. We therefore suggest an early and comprehensive bio-psycho-social assessment and therapy of HIV-infected patients.

Interleukin-1beta: a bridge between inflammation and excitotoxicity?

Interleukin-1 (IL-1) is a proinflammatory cytokine released by many cell types that acts in both an autocrine and/or paracrine fashion. While IL-1 is best described as an important mediator of the peripheral immune response during infection and inflammation, increasing evidence implicates IL-1 signaling in the pathogenesis of several neurological disorders. The biochemical pathway(s) by which this cytokine contributes to brain injury remain(s) largely unidentified. Herein, we review the evidence that demonstrates the contribution of IL-1beta to the pathogenesis of both acute and chronic neurological disorders. Further, we highlight data that leads us to propose IL-1beta as the missing mechanistic link between a potential beneficial inflammatory response and detrimental glutamate excitotoxicity.
