dc.description.abstractA pilot study was undertaken to investigate the effects of the intake of capsules containing the plant sterols and sterolins (BSS:BSSG mixture) on selected immune parameters of volunteers participating in an ultra-marathon in Cape Town, South Africa. Those runners having received active capsules (n = 9) showed less neutrophilia, lymphopenia and leukocytosis when compared to their counterparts having received placebo capsules (n = 8): the placebo treated individuals showed significant increases in their total white blood cell numbers as well as in their neutrophils (p = 0.03 and 0.03 respectively). Furthermore, statistically significant increases within lymphocyte subsets were observed in the runners having received the active capsules: CD3+ cells increased (p = 0.02) as did CD4+ cells (p = 0.03). In parallel, the BSS:BSSG capsules decreased the plasma level of IL6 in the runners using the active capsules (p = 0.08) and significantly decreased the cortisol: DHEAs ratio (p = 0.03), suggesting that these volunteers had less of an inflammatory response and were less immune suppressed during the post-marathon recovery period. These findings justify further investigations into the use of the phytosterols to prevent the subtle immunosuppression associated with excessive physical stress.
