  1. Effects of occupational lead and cadmium exposure on some immunoregulatory cytokine levels in man.

    Article - En anglais

    The levels of serum interleukin-1bêta (IL-1bêta), interleukin-2 (IL-2), tumor necrosis factor alpha (TNF-alpha) and gamma-interferon (gamma-IFN) were assessed in the workers who were occupationally exposed to lead and cadmium.

    The values were compared with the age-matched control group.

    Blood lead and cadmium levels were significantly raised.

    Our findings suggest that chronic lead and cadmium exposure in humans resulted in significant suppression of the serum IL-1bêta level, but did not alter IL-2 and TNF-alpha levels.

    The gamma-IFN level was also reduced in lead workers.

    In contrast, a significant enhancement was observed in the cadmium-exposed group.

    We conclude from these results that lead and cadmium exposure at chronically high level may affect some cytokine levels in humans.
