Role of CD4+ and CD8+ T Lymphocyte in the Onset of Stroke in People Living with HIV in Pointe-Noire

Abstract

Objective: To determine the role of CD4+ and CD8+ T lymphocytes in the onset of stroke in people living with HIV. Methodology: This was a descriptive, cross-sectional study from January to July 2019, in the neurology department of loandjili general hospital, including any patient hospitalized for a first episode of stroke confirmed by brain scan. The study variables were: age, sex, CRP value, serum T cell CD4+, CD8+. The statistical analysis was carried out using the EPI info 7 software. Results: Twenty stroke patients were in-cluded. The relative frequency of HIV was 20%. The risk factors were potentiated by immunosuppression of CD4+ T cells. Sixty percent (60%) of the patients had a CD4+ count < 200/mm 3 and the mean CD4+ count was ±191/mm 3 . Stroke was the predominant mechanism of injury with a frequency of 70%, the only injury mechanism of stroke in patients with CD8+ T cell count > 800/mm 3 (p = 0.04). Conclusion: Risk factors are potentiated by TCD4+ lymphocyte immunosupression, also CD8+ lymphocytes of immune system activation marker are a cardiovascular risk factor for living people with HIV.
