The leucocyte migration inhibition test (LMT) was performed by the agarose plate method with thyroid and pancreatic antigens in patients with insulin-dependent or independent diabetes mellitus. The mean migration indices with thyroglobulin, thyroid mitochondria and beef insulin were not significantly different in insulin-dependent diabetics from those in insulin-independent diabetics or normal controls. However, significant inhibition of leucocyte migration was observed in insulin-dependent diabetics when thyroid microsome or pancreatic extract was used as antigen. Although no significant difference was found in the percentages of T and B lymphocytes between insulin-dependent diabetics and insulin-independent diabetics or normal controls, the results of LMT strongly suggest the presence of cellular immunity against the thyroid and pancreas in insulin-dependent juvenile-onset diabetes.

The sera for 88 parents and 9 siblings of 73 patients with insulin dependent diabetes mellitus in childhood and 437 controls matched in age and sex, were tested by the thyroglobulin and microsome-coated tanned red cell hemagglutination test (Fuji-Zoki Co. Tokyo). None of 73 children with diabetes mellitus had antithyroglobulin antibodies, whereas twelve (16.4%) had antimicrosomal antibodies compared with the incidence of 0.4% and 1.1%, respectively, in 437 controls. In the parents and siblings of these probands, thyroid antibodies were also found in increased incidence. The incidence of antimicrosomal antibodies in the 68 mothers was significantly higher than in controls matched for age and sex, but the incidence of the positive thyroid antibodies in the 20 fathers and 9 siblings was not significantly different from that in control populations. The incidence of thyroid antibodies tended to be higher, though not significant, in parents and siblings of diabetic children with positive thyroid antibodies than in those of diabetics with negative ones. These findings suggest that immunogenetic factors may be responsible for the pathogenesis of some cases of diabetes mellitus in childhood.

Schmidt's syndrome (thyroid and adrenal insufficiency) and concurrent diabetes mellitus represent an intriguing multiple endocrinopathy in children. This report describes an eleven-year-old girl with diabetes of eight years' duration presenting in adrenal crisis. Serum thyroxine was undetectable, and antibodies to both thyroglobulin and adrenal tissue were found in high titer. The child's condition stabilized with hormonal replacement therapy, except for persistent growth failure. Approximately two years later she succumbed during a rapidly fulminant episode of ketoacidosis. The natural history of her illness supports recent speculation based on serologic data that juvenile diabetes mellitus may be an immunologic disorder in some children.

The purpose of our study was to determine the incidence of thyroid antibodies in diabetes mellitus in childhood and to discuss the correlation between thyroid antibodies and insulin antibodies. The sera of 50 children with diabetes mellitus and 437 children as disease controls were tested by thyroglobulin and microsome-coated tanned red cell hemagglutination test (Fuji Zoki Co. Tokyo). One of the 50 children with diabetes mellitus (2%) was positive with antithyroglobulin antibodies and eleven (22%) were positive with antimicrosomal antibodies compared to 0.4% and 1.1% respectively in 437 disease controls. To clarify the association of insulin antibodies and thyroid antibodies in diabetes mellitus in childhood, insulin antibodies were demonstrated by using a modified method described by Wright. One of the 33 children with negative insulin antibody (2.8%) was positive with antithyroglobulin antibodies and eight (24%) were positive antimicrosomal antibodies. No evident correlation was observed between antithyroid antibodies and insulin antibodies.

Spuriously high value of serum free triiodothyronine (FT3: Amerlex free T3 kit, Amersham, UK.) was noted accidentally on routine laboratory examination of two clinically euthyroid patients (case 1: FT3; 18.5 pg/ml, FT4; 1.1 ng/dl, T3; 103 ng/dl, T4; 8.2 micrograms/dl, TSH; 1.74 microU/ml, case 2: FT3; 8.5 pg/ml, FT4; 1.1 ng/dl, T3; 137 ng/dl, T4; 8.9 micrograms/dl, TSH; 1.45 microU/ml), the former with poorly controlled diabetes (FBG 253 mg/dl, HbA1c 12.1%) and the latter with essential hypertension (184/108 mmHg). Although the hypertensive patient showed mild diffuse goiter, there was no evidence that the patients had autoimmune thyroid diseases because anti-thyroglobulin antibody tests measured by radioimmunoassay and MCHA, TGHA or TBII were all negative. Their serum levels of TBG were within the normal range. Further studies revealed that both patients' sera had unusual binding activity to labelled polyaminocarboxy T3 (125I-aT3) but not labelled T3 (125I-T3). Furthermore, this binding protein was precipitated by goat anti-human immunoglobulin G (IgG). The IgG purified from both patients' sera also showed strong binding activity to 125I-aT3, which was inhibited by unlabelled T3 in a dose dependent manner. In conclusion, we found anti-T3 antibody in two clinically euthyroid patients with no apparent evidence of complicating autoimmune thyroid diseases. The stronger binding activity to polyaminocarboxy T3 rather than T3 may lead to the spuriously high value of serum FT3. The mechanisms of the production of such autoantibodies in our cases should be further investigated.

The effect of cholera toxin (CT) on the thyroid-pituitary axis and the immune system was examined in Bio-Breeding/Tokyo (BB/TKY) rats, which spontaneously develop insulin-dependent diabetes mellitus (DM) and lymphocytic thyroiditis (LT). Intravenous administration of CT (5 micrograms/100 g body weight) every other week starting at 6 weeks of age resulted in a significant decrease in the serum thyrotropin (TSH) level at 12 and 14 weeks of age when compared with saline treated littermates. CT stimulated rat thyroid cells to proliferate in vitro. Furthermore, serum anti-thyroglobulin antibody (ATA) titers were also significantly decreased in 14-week-old rats treated with CT. In vitro ATA production by spleen cells from BB/TKY rats was inhibited by CT. Antibodies to thyroxine were detected in both CT-treated and control rats. It is of interest that the ratio of W3/25+ helper/inducer cells to OX8+ suppressor/cytotoxic cells was significantly decreased in CT-treated rats. However, there was no significant difference in the incidence of DM and LT between the two groups of rats. The present study showed that CT suppressed ATA production both in vivo and in vitro, and had a stimulatory effect on thyrocytes in BB/TKY rats.

To see whether or not there is complement activation in patients with diabetes mellitus, we investigated the plasma concentrations of C4, C3, C4a, C3a and SC5b-9 in either juvenile or adult onset insulin-dependent (IDDM) and non-insulin-dependent (NIDDM) diabetic patients at least 2 years after diagnosis. C4, C3, SC5b-9 plasma levels were not significantly different in IDDM and NIDDM patients than in age-matched controls. Anaphylatoxin peptide conversion product C4a, but not C3a, was found significantly higher in adult-onset IDDM patients than in patients with juvenile onset IDDM, NIDDM patients and age-matched controls. Complement activation did not appear to be correlated with the metabolic control, nor the duration of disease nor the presence of circulating antibodies (including islet cells (ICA), insulin (IA), thyroid microsomal (TMA), and thyroglobulin (TGA)). Although there are many factors that may trigger complement activation, we found the highest levels of C4a in elderly subjects (both diabetics and control subjects) and particularly in those who had clinically detectable vascular complications.

No marker except repeated fasting glucose determinations has proven useful to ascertain prospectively which women with gestational diabetes mellitus will remain euglycemic by diet modification or will require insulin therapy. We screened 183 black women with gestational diabetes mellitus to determine if the presence of islet cell, mitochondrial, nuclear, DNA, parietal cell, smooth muscle, thyroid microsomal, thyroid thyroglobulin autoantibodies, or rheumatoid factor predicted the need for insulin therapy to maintain euglycemia in women with gestational diabetes mellitus. One hundred forty-two women maintained normal fasting plasma glucose levels with dietary modifications and 41 required institution of split-dose insulin therapy. We found no significant differences in the prevalence of these autoantibodies in black women with Class GB versus Class A1 diabetes mellitus. We conclude that screening for autoantibodies in women with gestational diabetes mellitus is not useful in determining which patients will subsequently require insulin therapy during their pregnancies.

Insulin-dependent diabetes is associated with other autoimmune diseases and subclinical hypothyroidism has been reported in pregnant diabetic women. We studied the thyroid function of 85 women with diabetes during pregnancy and after delivery, as well as various autoantibodies. During pregnancy, thyroid microsomal antibodies were present in 17/85, antibodies against thyroid peroxidase in 16/85, thyroglobulin antibodies in 2/85, parietal cell antibodies in 23/85, adrenal antibodies in 4/77, rheumatoid factor in 15/85, and thyroid-stimulating antibodies in 43/85. Presence of antibodies was not combined with thyroid dysfunction, but TSH and HbA1c was increased (p less than 0.005) in women with thyroid antibodies. The gestational age of the infants was lower (p less than 0.01) in women with positive thyroid-stimulating antibody titre, whereas the ponderal index was only lower in those with peroxidase antibodies (p less than 0.05). After delivery, microsomal and peroxidase antibodies were positive in 10 (17.5%) of 57 patients followed. Six women developed postpartum thyroiditis (10.5%), of whom 5 were positive for both microsomal and peroxidase antibodies; two of those showing a hyperthyroid phase also had positive thyroid-stimulating antibody titre. We conclude that autoantibodies occur with increased incidence in pregnant diabetic women. Thyroid antibodies are related to a slightly reduced thyroid capacity and involve a high risk of postpartum thyroiditis. Further, thyroid antibodies seem to influence the nutritional status of the infant.

Two clinically most widely used agglutination tests, Thymune and Serodia distributed by Wellcome and Fjirebio/Ames, respectively, to determine thyroid autoantibodies were compared. The Serodia tests seemed to be considerably more sensitive than the corresponding Thymune tests; first, Serodia tests resulted in several new positive samples and second, 16% and 30% of positive thyroglobulin and thyroid microsomal antibodies by Serodia resulted in at least 16 times higher titres, respectively. Over 300 healthy blood donor sera were used to determine the occurrence of thyroid autoantibodies in normal population. Titre limits of 400 and 6400 in anti-thyroglobulin and anti-microsomal antibodies were adapted for clinical use, respectively, even though the results suggested that the lower titre limits could be applied for males and subjects younger than 40 years. These defined titre limits were applied to examine randomly selected clinical patient material gathered during 1 year. The main patient groups identified included patients with chronic thyroiditis, thyroid malignancy, diabetes. Graves' disease and rheumatoid diseases as well as patients with vaguely defined clinical conditions. Without the aid of antithyroglobulin antibodies only one patient with chronic thyroiditis would have been missed if thyroid microsomal antibodies were used alone. Thus, in general clinical practise thyroid microsomal antibodies can be used as a sole diagnostic test for autoimmune thyroid diseases.
