Thyroid dysfunction and rheumatic diseases.

Musculoskeletal symptoms developing during the treatment of thyroid disease were studied in 150 patients; 17 developed a symptom complex of early morning stiffness together with shoulder girdle pain and weakness; similar symptoms were seen in only 3 of 100 controls. A prospective study of 16 patients with recent onset rheumatoid arthritis followed during the first 6 months of penicillamine therapy showed no changes in thyroid function tests. It is suggested that changing or abnormal thyroid status may precipitate or exacerbate musculoskeletal disease. Finally, in a retrospective study of 26 patients with both thyroid disease and rheumatoid arthritis, 4 patients had a simultaneous onset of both myxoedema and rheumatoid arthritis, the activity of which was greatly improved by correction of the hypothyroid state.

Thyroid disease in middle-aged and elderly Swedish women: thyroid-related hormones, thyroid dysfunction and goitre in relation to age and smoking.

The prevalence of thyroid disease and the concentration of thyroid hormones and thyrotropin were studied in a random population sample of 1154 women, aged 50-72 years, with special reference to the effect of age and smoking. The prevalence of spontaneous hypothyroidism was 3.3% (previously unknown overt and mild disease 1.3%) and the prevalence of hyperthyroidism was 2.5% (previously unknown disease 0.2%). Clinically suspected hyper- or hypothyroidism (very weak to strong) was recorded in 288 women, but was only verified in three cases. The prevalence of visible and palpable thyroid enlargement was 2.1% and 13-14%, respectively. Total thyroxine concentrations increased and free tri-iodothyronine levels decreased significantly with age (P less than 0.001). The serum thyrotropin concentrations were lower in smoking women than in non-smokers in the 50- and 58-year age groups (P less than 0.05). There was no increase in the prevalence of thyroid disease or goitre in the women who were smokers at the time of the study.

The prevalence of thyroid dysfunction in mentally handicapped in-patients.

A survey was made of the thyroid function of 402 mentally handicapped patients in a long-stay hospital and its satellite units. The prevalence of hypothyroidism in a 2-year period was 25/402 (6.2%), and 17/364 (4.7%) when people with Down's syndrome were excluded. Hyperthyroidism was found in 3/402 (0.7%). These results include 16 patients with hypothyroidism, and two with hyperthyroidism, who were newly detected during the surgery. With diagnosis, treatment was started. This occurrence of thyroid disorders is higher than in both the general population in the community and also in other psychiatric in-patients. Biochemical investigation is essential as the disorders are difficult to detect clinically, and untreated the patients are liable to the complications of hypothyroidism and hyperthyroidism.

Alterations of carboxypeptidases N activities in patients with thyroid dysfunction.

Serum carboxypeptidases N (EC. 3.4.17.3) were determined spectrophotometrically in 87 patients with disturbances of thyroid function and in 131 euthyroid individuals, including 33 women taking estrogens for contraception. Carboxypeptidases N (CN) can be subdivided into CN1 and CN2, according to variable substrate affinity. In addition, measurements of blood pressure and in vitro tests of thyroid function were performed. In euthyroid controls, CN1 was negatively correlated with age. No significant differences between CN1 and CN2 have been observed with regard to sex. In patients with hyperthyroidism, the mean values of both enzymes were elevated, but this tendency proved to be significant only for CN2. In hypothyroid patients CN1 and CN2 levels were normal. Elevations of CN1 and CN2 in the hyperthyroid state seem not to be related to underlying immunological processes but to the thyroid hormone excess itself. In euthyroid women taking estrogens for contraception CN2 was also elevated.

Auditory brain stem responses in thyroid dysfunction.

A characteristic pattern of ABR was observed in hyper-and hypofunction of the thyroid gland. The most conspicuous change took place in the BSCT. Its value correlated well with the level of serum T4. Dynamic changes of ABR pattern were recorded during the development of myxedema and on return to an euthyroid state. This preliminary study suggests that examinations of ABR may serve as a tool in the overall assessment of thyroid status.

Thyroid dysfunction following bone marrow transplantation: long-term follow-up of 80 pediatric patients.

Thyroid function was evaluated in children surviving disease-free for 2 years or more following bone marrow transplantation (BMT) for severe aplastic anemia (27 patients), acute non-lymphoblastic leukemia (28 patients), and acute lymphoblastic leukemia (25 patients). Pre-BMT conditioning consisted of high dose chemotherapy and total lymphoid irradiation with 750 cGy for patients with severe aplastic anemia, and for patients with leukemia, high dose chemotherapy and single dose total body irradiation with 750-850 cGy (33 patients) or fractionated total body irradiation with 1320 cGy (20 patients). Compensated hypothyroidism (elevated thyroid stimulating hormone (TSH) with a normal thyroxine index) occurred in 20/80 patients with a median time of onset of 12.3 months post-BMT (range 4-30). No patients developed primary hypothyroidism (elevated thyroid stimulating hormone with low thyroxine index). In seven patients, compensated hypothyroidism was transient with TSH returning to normal at a median of 60 months post-BMT (range 11-75). Six patients with compensated hypothyroidism received thyroid hormone replacement therapy. Time to development of compensated hypothyroidism was associated (p = 0.03) with underlying disease and radiation (11 of 27 patients with severe aplastic anemia + total lymphoid irradiation versus nine of 53 patients with leukemia + total body irradiation). In aplastic anemia patients, but not patients with leukemia, the incidence of thyroid hypofunction 5 years post-transplant was significantly higher (p less than 0.001) in those receiving methotrexate alone (82%) as prophylaxis for graft-versus-host disease compared with those receiving a regimen of methotrexate, antithymocyte globulin and prednisone (16%).

Evaluation of a new strategy for detection of thyroid dysfunction in the routine laboratory.

We assessed the use of a new strategy for detecting thyroid disorders, utilizing a sensitive assay for concentrations of thyrotropin (TSH) and free thyroid hormone in serum as follow-up tests. Of 1279 patients who were not on thyroxin (T4) replacement treatment, 82% could be classified as euthyroid and would require no further tests. In patients who were on T4 replacement, 41% fell into the euthyroid category and would require no further tests. Using this strategy to replace our existing strategy of free thyroxin as a "first-line" test would reduce the proportion of patients who would require one or more follow-up tests from 49% to 24%.

Significance of thyroid dysfunction in human cardiac allograft procurement.

Twenty-two potential cardiac allograft donors had evaluation of thyroid function performed just prior to cardiectomy. Despite statistically significant abnormal thyroid function, no correlation to graft function or failure was observable. Multiple myocardial microinfarcts, undetected at the time of donor selection were detected in two hearts that were abandoned prior to transplantation and possibly another heart that failed as an allograft in a heart-lung transplant recipient.

Adrenal and thyroid dysfunctions in experimental Trypanosoma congolense infection in cattle.

Severe pathological changes were observed in the adrenal and thyroid glands of Zebu (Bos indicus) heifers infected with Trypanosoma congolense. In the adrenal glands, severe inflammatory changes characterised by mononuclear cellular infiltration in the subcapsular areas, zona glomerulosa, zona fasciculata and zona reticularis were observed. In addition, there were hyperaemia, haemorrhage and hyperplasia resulting in increased adrenal weight in the two heifers slaughtered on Days 50 and 70 post-infection (p.i.). In the medullary areas of these two heifers, there was only mononuclear cellular infiltration. In the two heifers slaughtered on Day 113, localised mononuclear cellular infiltration was observed in addition to cortical cell depletion and fibrosis, resulting in reduced adrenal weight when compared with the controls. In the thyroid glands of the infected heifers, gross enlargement of the follicles filled with pale staining colloids were observed in association with squamous metaplasia of the follicular epithelium and fibroplasia. Serum cortisol concentrations showed an appreciable but non-significant increase (P less than 0.05) between Weeks 2 and 6 p.i. in the infected heifers (5.6 +/- 0.86 ng ml-1 vs. 4.4 +/- 0.34 ng ml-1) when compared with the uninfected controls or the pre-infection level. Thereafter, cortisol levels declined though non-significantly throughout the rest of the study. However, there was a steady increase towards normal levels from Week 12 p.i. until the end of the experiment. Changes in the basal serum concentrations of thyroxine (T4) were also measured weekly. There was a progressive decrease in the levels of T4 from the third until the 11th week p.i., when the decrease became significant (P less than 0.05) and remained so until the 16th week when the experiment ended.
