Abstract

Objectives: Neuromodulation of the immune system has been proposed to be influenced by hemispheric lateralisation (HL). The present study tested whether HL predicted CD4+ levels, statistically controlling for confounders. Methods: Employing two assessments of HL, 68 human immunodeficiency virus (HIV)-1+ patients were followed prospectively. Numerous exclusion criteria and confounder assessments were employed (e.g. age/medication). Results: Left HL significantly positively predicted CD4+ levels at follow-up, and this was qualified by medication (HAART) status: only in HAART-naïve patients did HL predict CD4 levels. Furthermore, HL significantly predicted whether patients had clinically significantly high/low CD4+ counts. Conclusions: Using a more rigorous methodology than a previous study, the present work partly corroborated the theory of HL influences on immunity, extended it to HIV immunity and identified a possible moderator: HAART medication. Implications for future research and treatments are provided.
