The incidence of pregnant women with thyroid dysfunction has been reported to be around 0.1-0.4%. Graves' disease accounts for more than half of these disorders. The main cause of thyroid disease in pregnancy and puerperium is autoimmune dysfunction. Whether there may be goitre or exophthalmus present, clinical signs as inappropriate weight gain, high systolic pressure, palpitation (greater than or equal to 110/min), emotional lability, fatigue, acceleration of suppression of the Achilles' tendon reflex should induce changes in the biochemical thyroid function tests. Parameters for the diagnosis and management for hyperthyroidism are serum levels of free T4 and TSH, while those of T3, reverse T3, and TSH are for hypothyroidism. Serum anti-microsomal antibodies and anti-thyroglobulin antibodies which have no effect on the fetus are also good markers for severity. The transplacental transfer of maternal TSH receptor antibodies consisting of stimulatory and inhibitory immunoglobulins and maternal thyroid-binding inhibiting immunoglobulins play roles in the development of transient neonatal hyper- or hypothyroidism. Fetal control is achieved by optimal maternal management. Untreated hyperthyroidism may be associated with fetal malformations. This risk may be reduced by antithyroid drug treatment of up to 150 mg/day of propylthiouracil which has less chance of placental passage and less secretion into the mother's milk than methyl-mercapto-imidazol. Maternal thyroid function should be kept in the upper limit of normal range, taking into consideration the fetal dysfunction induced by over-administration of the drug which passes through placenta. Children of hypothyroid women taking inadequate replacement therapy manifested lower IQ values compared to the progeny of euthyroid or hypothyroid women taking adequate therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

Anti-thyroid peroxidase antibodies were prospectively assayed and compared with anti-microsome and anti-thyroglobulin antibodies in 203 patients (188 women, 15 men; mean age 42 +/- 14 years). These patients consulted for hyperthyroidism (n = 42, including 18 with Graves' disease), fumary hypothyroidism (n = 50, including 20 at the diagnosis stage), euthyroid diffuse or nodular goitre (n = 81) or benign euthyroid nodule (n = 14). Sixteen patients examined for fatigue, gynecomastia, menstrual disorders or overweight had normal thyroid function. Anti-thyroid peroxidase, anti-microsome and anti-thyroglobulin antibodies were assayed by radioimmunology or indirect immunofluorescence. Anti-thyroid peroxidase antibodies were most frequently present in patients with autoimmune thyroid diseases, such as Graves' disease (72%) or primary hypothyroidism (70%), and correlated with anti-microsome antibody levels (r = 0.87; p less than 0.001). Anti-thyroid peroxidase antibodies were absent in patients with benign euthyroid nodule; they were present in 22% of patients with euthyroid goitre and in 12% of control patients; their level decreased during replacement therapy for hypothyroidism. It is concluded that radioimmunological assays of anti-thyroid peroxidase antibodies should replace anti-microsome and anti-thyroglobulin antibodies in thyroid evaluation.

A 47-year-old housewife was admitted to our hospital because of general fatigue and constipation suggesting hypothyroidism. For 3 years before admission, general fatigue, arrhythmia, dry skin, drowsiness, cold intolerance and hypermenorrhea occurred insidiously. She had habitually taken considerable amounts of seaweed every day, e.g. more than 50 g of " Kombu " for more than 5 years and at least 1 g of " Wakame " for 6 months. On admission, serum thyroxine (T4) was 1.3 micrograms/dl, serum triiodothyronine (T3) was 47 ng/dl, TSH was 132 microunits/ml, and 123I thyroidal uptake was 60% at 3 hr. and 75% at 24 hr. Anti-thyroglobulin hemagglutination antibodies and anti-thyroid microsomal hemagglutination antibodies were both negative. When seaweed was omitted from her diet, T4 rose to 6.3 micrograms/dl and T3 rose to 113 ng/dl, whereas TSH lowered to 11 microunits/ml in 2 weeks. The seaweed-free diet was continued and 4 months later, when she had become euthyroid, an open biopsy of the thyroid gland was carried out. Histological examination of the specimen revealed a marked colloid deposition without characteristic features of Hashimoto's disease. Five months after admission, with the daily administration of 100 mg potassium iodide (KI), the effects of inorganic iodide on thyroid function had begun to be seen. On the 16th day of the KI regimen, palpitation and tachycardia (pulse rate 160/min.) with multifocal ventricular premature beat appeared, and T4 on the 11th day was 5.9 micrograms/dl, which was clearly lower than the pretreatment level of 8.4 micrograms/dl. KI was discontinued on the 16th day, and one week after the withdrawal, T4, T3 and TSH all returned to the pretreatment level. For more than 3 years on a seaweed-free diet, she remained euthyroid without any thyroid regimen. To see the effects of inorganic iodide on thyroid function after this long period on a seaweed-free diet, KI was again administered. One hundred mg/day KI for 14 days followed by 200 mg/day for 21 days had virtually no effect on T4, T3 and free T4 and she remained well. None of the perchlorate discharge tests performed on 3 occasions during the 6 month period after the initiation of the seaweed-free diet showed a discharge.(ABSTRACT TRUNCATED AT 400 WORDS)

Diverse immunologic abnormalities have been described in women who received silicone breast implants. However, most studies have focused on either a limited number of patients or a small panel of autoantibodies. We report the analysis of 20 autoantibodies in 116 women with implants and 134 controls. The patients ranged from 26- to 66-years-old, with a mean of 45.7 +/- 8.3 years; breast prostheses were in place for a mean of 15 +/- 5.6 years, with a range of 4 to 30, the chief complaints of the 116 patients included polyarthralgias, fatigue, myalgias, morning stiffness, and decreased memory. All 250 sera were tested blindly using a panel of 20 autoantigens including SS-A, SS-B, RNP, cardiolipin (CL), collagen types I, II and IV, phosphatidylserine (PS), myeloperoxidase (MPO), sulfatides (sulf), thyroglobulin (TG), gangliosides (GDIa;GM2), proteinase-3 (PR3), Jo-1, Sm, HPRPP-ribosomal phosphate, histones (H2AH2B), Scl-70 and glomerular basement membrane (NC-1). Values from individual patients were considered positive only when greater than 3 SD above the control mean. There was a statistically significant greater frequency of autoantibodies in women with implants for 15 of the 20 autoantigens; these were particularly striking for anti-H2AH2B, HPRPP, SS-A, SS-B, Scl-70, CL, PS, GM2, and NC-1. Many patients harbored several autoantibodies; 20% had four autoantibodies; 8% had six autoantibodies. The association of autoantibodies and implants suggests an adjuvant action of silicon/silicone byproducts.

Postpartum thyroiditis (PPT) occurs in 5%-9% of unselected postpartum women; hyperthyroidism and hypothyroidism develop, the latter being permanent, in up to 25 %-30% of women. PPT is strongly associated with antithyroid peroxidase (anti-TPO) antibodies, but 50% of anti-TPO positive women do not develop thyroid dysfunction. Symptom analysis has shown that lack of energy and irritability were the most frequent hyperthyroid symptoms whereas lack of energy, aches and pains, poor memory, dry skin, and cold intolerance were the significant hypothyroid features. Some of these symptoms were more frequently observed than in antibody-negative controls even when these patients were euthyroid and in anti-TPOAb positive women who did not develop PPT at all. The diagnosis of PPT is based on the observation of abnormal thyroid function tests in a postpartum anti-TPOAb-positive woman: transient hyperthyroidism occurs at 14 weeks and hypothyroidism at 19 weeks postpartum. Diffuse or multifocal hypoechogenicity of the thyroid is seen on echography and a thyroid destructive process is evidenced by an increase in serum thyroglobulin and urinary iodine excretion. In addition to the 25%-30% of women who develop permanent hypothyroidism at 3 years, recent data indicate that 50% of women who have developed PPT will be hypothyroid 7-9 years later. The long-term risk is only 5% for those anti-TPOAb positive women not developing thyroid dysfunction postpartum. The risk of recurrent PPT is 70% if previous PPT was experienced and 25% if the patient was euthyroid after the first pregnancy.

A 44-year-old woman presented to her GP with excessive tiredness. She had positive thyroid microsomal and thyroglobulin autoantibodies and was found to have an elevated serum thyroid-stimulating hormone (TSH) concentration of 8.37 (normal = 0.15-3.5)mU/L and a low normal total thyroxine (T4) of 86 (reference range 60-145)nmol/L. She was rendered symptom free on a dose of 150 microg of thyroxine per day. However, her TSH failed to return to normal, and following a further increase in her thyroxine dose she was referred to the endocrine clinic for further assessment. Her TSH at this stage was 14mU/L, free T4 (fT4) 28 (normal = 10-27)pmol/L and free T3 (fF3) 10 (normal = 4.3-7.6)pmol/L. She denied any problems with adherence to her medication. Her serum prolactin was elevated at 861 (normal = 60-390)mU/L. A pituitary tumour was suspected and an MRI scan showed a macroadenoma of the right lobe of the pituitary, extending into the suprasellar cistern. The tumour was resected trans-sphenoidally. Electron microscopy showed a dual population of neoplastic cells compatible with a thyrotroph cell and prolactin-secreting adenoma. Immunocytochemistry and cell culture studies confirmed the secretion of TSH, prolactin and alpha-subunit. Postoperative combined anterior pituitary function tests did not demonstrate any deficiency of anterior pituitary hormones. A repeat MRI scan showed no significant residual tumour; however, her serum TSH and prolactin levels remained high and she was given a course of pituitary irradiation. This case illustrates the difficulty of diagnosing a TSHoma when it coexists with autoimmune hypothyroidism. We believe the combination of pathologies reported here is unique.

Hypothyroidism with thyroglobulin antibodies during corticoid replacement in a 54-year-old man with isolated ACTH deficiency. HISTORY AND ADMISSION FINDINGS: A 54-year-old previously healthy man was admitted because of fatigue, tiredness, diarrhoea and weight loss for the last 3 years. Physical examination revealed dry but normally pigmented skin and markedly reduced Achilles reflex bilaterally. INVESTIGATIONS: Erythrocyte sedimentation rate was slightly elevated at 32 mm/h, C-reactive protein was normal. Both haemoglobin (12.4 mg/dl) and the corpuscular indices were normal, as were serum electrolytes, and sodium bicarbonate. But basal levels of thyroid stimulating hormone (TSH, 8.5 mU/ml) was markedly elevated, while free peripheral triiodothyronine (3.2pg/ml) was normal and free thyroxine (fT4) at 0.7 ng/d was slightly reduced. Thyroid ultrasound was normal. Test for antinuclear antibodies was slightly positive, but double-strand DNA was not demonstrated. Antithyroglobulin antibodies were slightly raised to 1012 IU/ml (normal <350). The basic level of ACTH was repeatedly below detection, as were plasma cortisol and cortisol excretion in 24-hour urine. Nuclear magnetic imaging was normal. Failure to stimulate corticol synthesis in the short ACTH test and by CRH indicated an isolated ACTH deficiency at the level of the anterior pituitary, while other hypophyseal functions were unaffected. TREATMENT AND COURSE: The patient"s condition rapidly improved on replacement with hydrocortisone, 30 mg/d, and thyroxine, 100 mg/d. No thyroglobulin antibodies or antinuclear antibodies were demonstrable after 6 months. Thyroxine was discontinued after 15 months. Frequent monitoring of thyroid function over the next 2 years always indicated a euthyroid state. CONCLUSION: Subnormal concentration of peripheral thyroid hormone combined with elevated TSH levels can, in the presence of hypercorticolism, be due to reversible abnormal thyroid function.

A 14-year-old girl was admitted because of general fatigue and cervical lymphadenopathy. She showed bilateral struma (IInd degree) and enlargement of her left cervical lymph nodes. Laboratory data revealed neutropenia (219/microliter) and thrombocytopenia (Plt 5.1 x 10(4)/microliter) with mild anemia (Hb 11.1 g/dl), and the bone marrow aspirate and biopsy specimens showed hypocellularity. In addition, auto-antibodies against thyroid peroxidase (TPO) and thyroglobulin (TG) were highly elevated. Computed tomography of the neck showed a nodule in the left thyroid lobe with marked lymphadenopathy, and fine needle aspiration biopsy demonstrated papillary thyroid carcinoma with Hashimoto's thyroiditis and metastasis to the lymph nodes. One month after left thyroid lobectomy and cervical lymphadenectomy, the patient's condition progressed to very severe aplastic anemia, and she received immunosuppressive therapy consisting of cyclosporin A and anti-thymocyte globulin. Hematologically, partial and complete responses were obtained three and six months later, respectively. Of interest, anti-TPO and TG antibody titers remarkably decreased after immunosuppressive therapy. The patient had HLA-DR 2(DRB 1*1501) and DR 8(DRB 1*0802). The former is frequently found in patients with cyclosporin A-dependent aplastic anemia, and the latter is frequently found in Asian patients with Hashimoto's thyroiditis, suggesting an underlying autoimmune background for the simultaneous outbreak of aplastic anemia and Hashimoto's thyroiditis complicated by thyroid carcinoma.

A 81-year-old woman was diagnosed as having diabetes mellitus (DM) at 58 years of age. She started insulin therapy the following year, but her blood sugar levels were poorly controlled. At the age of 75, she tested positive for the anti-GAD antibody (7.8 U/ml) and was diagnosed as having slowly progressive type 1 DM (SPIDDM), as well as vitiligo vulgaris. At 78 years of age, chronic thyroiditis was diagnosed after positive tests for anti-thyroid peroxidase antibody and anti-thyroglobulin antibody. At the age of 81, general fatigue and jaundice appeared concomitantly with severe anemia, with Hb levels at 5.2 g/dl. Low serum vitamin B12 levels and the finding of erythroblastic hyperplasia with megaloblasts in bone marrow led to the diagnosis of pernicious anemia. Anemia was alleviated by intramuscular injections of vitamin B12. The patient developed chronic thyroiditis, vitiligo vulgaris, and pernicious anemia concomitantly with SPIDDM, and was diagnosed as having polyglandular autoimmune syndrome type III. Attention should be paid to these potentially associated autoimmune diseases in daily practice during the follow-up of SPIDDM patients.

A 46-year-old man presented with frontal headache, a visual field defect and general fatigue. Magnetic resonance imaging (MRI) of the brain showed symmetrical enlargement of the pituitary gland and stalk due to the presence of a mass lesion extending toward the optic chiasm. Gadolinium injection further revealed homogeneous strong enhancement with involvement of the adjacent dura (dural tail). Basal plasma levels of ACTH, free thyroxine and gonadotropins were decreased, and 24-h urinary 17-OHCS excretion was reduced. An elevated anti-thyroglobulin antibody titer indicated the presence of autoimmune thyroiditis. Under the suspicion of autoimmune hypophysitis, 60 mg/day prednisolone sodium succinate was intravenously administered for two weeks followed by a decreasing dose of oral prednisolone. Clinical symptoms and pituitary dysfunction recovered during steroid treatment and MRI showed marked shrinkage of the pituitary mass. Early initiation of an intravenous dose of glucocorticoid followed by oral steroid administration therefore seems to be an efficient treatment for autoimmune hypophysitis even in patients with visual dysfunction.
