Urinary amine alterations in drug-addiction pregnancy.
Urinary amines were measured in 122 drug-addiction pregnancies. The profile of the patient indicates that 86 per cent were black and had a total of 2.98 pregnancies and 1.97 living children. She made 5.4 prenatal visits to our special drug-abuse prenatal clinic. The 208 antepartum 24 hour urine determinations indicated a mean excretion of epinephrine to be 28 +/- 1.6 mug which rises to 60 mug on the first day post partum. These values indicate increased adrenal gland activity and are more than six times greater than seen in normal pregnancy. The antepartum mean 24 hour urine excretion of norepinephrine is 49.7 +/- 2.6 mug which does not change on the first postpartum day. The antepartum norepinephrine values are 50 per cent higher than seen in normal pregnancy. Drug-addiction pregnancy in patients who are well controlled on methadone have markedly increased adrenal gland activity as evidence by increased levels of epinephrine. The sympathetic nervous system activity as evidenced by urinary norepinephrine is only slightly increased. Drug addiction alters the normal homeostatic mechanisms of pregnancy.
