Alterations in peripheral blood leukocyte distribution in major depression, including leukocytosis, neurotrophilia and lymphopenia, have been described. To assess peripheral white blood cells and the hypothalamic-pituitary (HP) axis in drug-free patients with major depression, we measured the total white blood cell count (WBC), and percentage of lymphocytes, and the plasma levels of cortisol, adrenocorticotropic hormone (ACTH), growth hormone (GH) and prolactin (PRL). Twenty male patients with major depression had relative lymphopenia and leukocytosis when compared with 20 age, sex and racematched control subjects. Elevated Beck and Hamilton depression scores correlated with a decreased percentage of lymphocytes, in a group of all subjects combined. There was a weak tendency for elevated growth hormone to correlate with relative lymphopenia in the control subjects only. Relative lymphopenia and leukocytosis may be a part of the psychobiology of major depression.

Domperidone, anti-emetic drug, given to healthy female volunteers, induced an elevation of plasma prolactin (PRL) concentration with the peak in 1-4 h. The release of prolactin had a transient stimulating effect on theophylline sensitive T lymphocytes and on concanavalin A induced mitogenic activity, suggesting an enhanced activity of T suppressor lymphocytes. The relative number of CD4+ lymphocytes decreased markedly one hour after domperidone administration and returned to normal values within 2 h (that means 3 h after taking the drug). The number of lymphocytes positive for dipeptidyl peptidase IV exhibited similar transient increase and normalization of activity. No change was observed in the number of CD8+ lymphocytes. The production of interferon by leukocytes treated with Newcastle disease virus was found to be significantly increased 2 h after domperidone administration. The results suggest that prolactin can selectively stimulate some functions of cellular immunity as well as the release of cytokines (IFN). The present study may contribute to the understanding of the role of the immune system in endogenous hyperprolactinemia.
