Thyroxine-binding globulin in spontaneous abortion.

Thyroxine-binding globulin (TBG), thyroxine-binding prealbumin (TBPA), thyroxine (T4), free T4, triiodothyronine (T3) and thyroid-stimulating hormone (TSH) were studied in 144 apparently healthy, euthyroid pregnant women displaying miscarriages. In an additional group of 18 aborting women a frozen blood sample drawn in early pregnancy was similarly analyzed for the thyroid components as well as for human chorionic gonadotropin (HCG). The values were compared to those of normal pregnancies (n = 228) at corresponding intervals. Significantly lower values of TBG were found in the spontaneously aborting group. A significantly lower value of TBG was found to be more predictive concerning spontaneous abortion than that of HCG.

Thyroid associated components in serum during normal pregnancy.

Thyroxine-binding globulin (TBG(, thyroxine-binding pre-albumin (TBPA), thyroxine (T4), free-T4, triiodothyronine (T3), and thyroid-stimulating hormone (TSH) were studied throughout apparently normal pregnancy in 290 cases grouped in 2 week intervals. TBG increased to a plateau level reached in the 24th week and was hereafter unchanged until term. T4 showed an increase until the 16th week of pregnancy and levelled off to a constant level for the rest of the pregnancy. Free-T4 declined to almost subnormal values for the non-pregnancy state which was reached around the 20th week of pregnancy. T3 showed a slight and definite increase in the beginning of pregnancy and levelled off to a constant value after the 14th week. TSH increased towards the end of pregnancy also showing its maximum during the last 4 weeks. TBPA showed constant values throughout pregnancy. The results are discussed in view of the use of modern techniques and previously missing data in literature (TBPA).
