ABSTRACT Crude IgG of sera from 3 patients with Graves' disease, which contained LATS-activity and/or thyroid antibodies, was fractionated by isoelectric focusing in a pH-range between 6.0 to 10.0. LATS-activity was found in IgG-subfractions from pH 7.5 to 9.5, thyroglobulin antibodies and thyroid microsomal antibodies from pH 6.0 to 10.0. It was not possible to separate LATS-activity from the thyroid antibodies by this technique. The results indicate that LATS and the thyroid antibodies are heterogeneous and of polyclonal origin.

Trophic Action

Abstract. A Turkish family with frequent intermarriages is described, in which two siblings were born with persistent forms of congenital hypothyroidism, in the elder child concomitant with absent radioactive thyroid imaging. The mother was clinically euthyroid throughout the period of observation, but showed in addition to thyroid microsomal antibodies, high levels of immunoglobulins blocking the trophic action of TSH. These maternal growth blocking antibodies were transiently present in the youngest of the siblings (from birth to 2 months of age). She had a relatively mild form of congenital hypothyroidism (T3: 33 μg/100 ml; T4: 3.9 μg/100 ml). The older sibling, with proven non-functioning thyroid tissue (negative thyroidscan, T4: 0.4 μg/100 ml) produced the growth-blocking immunoglobulins herself and may thus represent a juvenile form of thyroid autoimmunity with a very early onset. An aunt and uncle of the children, both hypothyroid since birth, were at the age of 19 and 18 years weakly positive for growth blocking immunoglobulins. This study indicates that familial forms of congenital hypothyroidism are probably complex and may be brought about by maternal to foetal passage of thyroid reactive autoantibodies, but also by the inheritance of a trait for thyroid autoimmunity. In some cases these two mechanisms might act in conjunction.

ABSTRACT Fourteen patients with Idiopatic Addison's disease (IAD) were studied in order to detect a possible subclinical hypothyroid state. All were clinically euthyroid with normal serum thyroxine (T4) and serum 3,5′,3′-triiodothyronine (T3). Eleven had circulating thyroid microsomal antibodies in blood. The mean basal serum TSH was significantly higher than that of the control group but only three patients had values above the upper normal range. The mean value of serum T4 was decreased as compared to that of the normal persons, while serum 3,3′,5′-triiodothyronine was elevated. 7.5 mU bovine thyrotrophin per kilogram body weight injected intravenously caused a rise in serum T3 not different from the response in normals. However, as well increasing serum TSH as increasing microsomal antibody titer correlated significantly to decreasing thyroidal release of T3. Our results suggest that clinically euthyroid patients suffering from IAD might have a beginning thyroidal insufficiency because of a progressive immunological damage of the thyroid.

Abstract. T-lymphocyte subpopulations, anti-thyroid microsomal antibody titres, and free triiodothyronine and free thyroxine levels were investigated in 10 patients with Graves' disease before, during and after pregnancy. Twenty pregnant subjects and 100 normal age-matched, non-pregnant female volunteers served as controls. Pregnant patients with Graves' disease showed decrease levels of free triiodothyronine and free thyroxine, and decreased titres of anti-thyroid microsomal antibodies, with clinical remission during the second and third trimesters of pregnancy. Post partum, 9 patients showed clinical relapse, and all showed a return of enhanced levels of free triiodothyronine, free thyroxine and anti-thyroid microsomal antibodies. The percentage and absolute number of total T-lymphocytes (OKT3+) and OKT4+ cells significantly decreased during pregnancy in patients with Graves' disease and in normal women. Post partum, OKT3+ and OKT4+ cells returned to pre-pregnancy levels in both groups. In Graves patients and in controls, the percentage and absolute number of OKT8+ cells during pregnancy and post partum were not significantly different from pre-pregnancy levels. Lastly, the OKT4+/OKT8+ ratio, which decreased in normal subjects at the three sampling times during pregnancy, decreased only in the last two trimesters of pregnancy in patients with Graves' disease.
