Plasma corticosteroid concentrations of seven Arab foals with combined immunodeficiency (CID) and five non-CID Arab foals were measured. Plasma corticosteroid concentrations were quantitated throughout gestation for ten mares heterozygous for the CID trait and pregnant with CID foals, as well as for 20 mares heterozygous for the CID trait and pregnant with non-CID foals. Five nonpregnant mares heterozygous for the CID trait also were tested during the same period. Concentrations of plasma corticosteroids in foals with CID (34.4 plus or minus 5.2 ng/ml) did not differ from those of non-CID foals (37.6 plus or minus 8.4 ng/ml). Differences in corticosteroid concentrations were not detected between mares pregnant with CID foals (61.5 plus or minus 16.4 ng/ml) and mares pregnant with non-CID foals (61.5 plus or minus 12.7 ng/ml) or between pregnant mares and nonpregnant mares (77.9 plus or minus 10.7 ng/ml).
