    International Symposium on Health Aspects of Environmental and Occupational Pesticide Exposure. Düsseldorf, DEU, 1998/09/28.

    Immune parameters were examined in 224 sera of non-exposed controls and in 304 sera of pesticide applicators in the agricultural environment.

    In comparison to the control group pesticide applicators showed significant increased odds ratios for neopterin and soluble tumor necrosis factor receptor (sTNF RII) and a decreased odds ratio for immunoglobulin M. Obtained results indicate an enhanced macrophage activation and an impaired humoral defense.

    These alterations have been found to correlate with exposure duration in the group of pesticide applicators in agriculture.

    For subjects who worked in indoor pest control an inverse correlation for sTNF RII with exposure duration was obtained indicating impairment of cell mediated immune function.

    It can be concluded that exposure to pesticides in the agricultural environment may contribute to modulation of the immune system.

    Since immune modulating agents can potentially lead to adverse health consequences the involvement of immune biomarkers in pesticide-related health studies seems to be of considerable value for risk assessment studies.
