  1. Occupational lead exposure and screening of glucose-6-phosphate dehydrogenase polymorphism : useful prevention or nonvoluntary discrimination ?

    Article - En anglais


    To discuss regulatory guidelines excluding subjects with erythrocyte glucose-6-phosphate dehydrogenase (G6PD) deficiency from lead-exposed jobs in the light of epidemiology findings on the mortality of these subjects.


    Two mortality follow-up studies were conducted.

    The first comprised 1979 male subjects newly identified as G6PD-deficient during a 1981 screening of the G6PD polymorphism among the general population in Sardinia, Italy.

    The second comprised 1080 male workers employed in maintenance and production departments of a lead smelting plant, who were divided into two subcohorts by erythrocyte G6PD phenotype.


    As compared with the general male population, G6PD-deficient subjects had significantly fewer deaths than expected from ischemic heart disease (standardized mortality ratio (SMR)=28 ; 95% CI 10-62), cerebrovascular diseases (SMR=22 ; 95% Cl 6 55), and liver cirrhosis (SMR=12 ; 95% Cl 0-66).

    Among lead smelters the standardized mortality rates from cardiovascular diseases and all cancers observed among the G6PD-deficient subcohort were lower than those seen among subjects with the wild-type G6PD.

    No death from disease of the blood and hematopoietic system was observed among G6PD-deficient subjects in these two follow-up studies.


    These studies did not provide evidence of hypersensitivity to lead hematotoxicity among G6PD-deficient individuals at exposure levels within the current standards. (...)
