- Abstract
In spite of data supporting the use of the serum thyrotropin (TSH) concentration as the best test to detect abnormal thyroid function, measurement of circulating thyroid hormones with or without a serum TSH continues to be frequently requested to evaluate thyroid function. We have analyzed how combinations of thyroid function tests were ordered by referring physicians and the results of the tests in order to offer some suggestions as to how to use thyroid function tests in a cost effective manner. During 1995, 19,181 inpatient and outpatient requests (45,865 different tests) for thyroid function tests were received by the laboratory of a 1600 bed University Hospital in Parma, Italy. The following tests were carried out: T4, free T4, T3, free T3 and TSH. Serum TSH values below and above the normal range were considered to reflect abnormal thyroid function i.e.hyperthyroidism, or hypothyroidism including subclinical disease independent of the results of the other tests. Combinations of ordered tests and the percent of the total for each combination were: TSH+T4+T3 (56%), TSH+FT4+FT3 (14%), TSH (12%), TSH+FT4 (9%), TSH+T4 (1%), TSH+T4+T3+FT4+FT3 (5%), others (3%). The T4+T3+TSH panel (10,780 requests) had normal serum TSH values in 80.6% and the FT4+ FT3+TSH panel (2,590 requests) had normal TSH values in 73.2%. Elevated serum TSH concentrations were observed more frequently in hospitalized than in ambulatory patients (9.7% vs 7.4% p<0.001). T3 (elevated serum T3, normal T4 and low TSH concentrations) and T4 (elevated serum T4, normal T3 and low TSH concentrations) toxicosis were observed in 8.1% and 9.4%, respectively, of the requested test (NS). FT3 and FT4 toxicosis, defined as for T3 and T4 toxicosis, were observed in 7.5% and 4.9%, respectively (NS). The low T3 and low FT3 syndrome in hospitalized patients was present in 1.6% and 2.3% of the requests, respectively (NS). The low T4+low T3 and low FT4+low FT3 syndrome was present in only 0.3% and 0.2%, respectively, of the requests. Our study shows that a) in hospitalized patients thyroid function tests were requested in 20% of the patients and only one in 14 of these patients at the highest could have abnormal thyroid function, as indicated by abnormal TSH value b) FT4 (or T4) is as useful as FT3 (or T3) in the diagnosis of hyperthyroidism, c) in hospitalized patients the low T3 syndrome was far less common than that reported in the literature, probably due to the lower severity of illness, d) panels which include T3 and FT3 are not justified, and e) serum TSH alone is the most appropriate initial thyroid function test.

- Abstract
Amiodarone induced thyrotoxicosis (AIT) occurs most frequently in euthyroid patients with nodular goiter or Graves’ disease due to release of iodine from this iodine rich drug. However, some cases of AIT have been attributed to an inflammatory process of the thyroid gland due to amiodarone itself.We have studied the echographic pattern of the thyroid in 11 euthyroid patients who had an episode of AIT 32.4±3.6 months earlier due to amiodarone induced thyroiditis. There was a significant increase in dyshomogeneous echo patterns and hyperechogenecity which suggests fibrotic lesions. These findings were similar to those observed in 10 euthyroid patients who 77±12 months earlier had an episode of subacute thyroiditis (SAT). Thyroid volumes of control subjects and patients with a history of AIT and SAT were 10.9±1.4, 8.7±1.4 and 9.8±1.7, in the order. These values were not significantly different. These echographic findings, normal serum thyroid hormone and TSH concentrations and the absence of circulating antithyroid peroxidase antibodies suggest that underlying thyroid autonomy and Graves’ disease were not the cause of the previous episode of AIT. The presence of hyperechogenic and dyshomogeneous patterns appears the result of the healing of the inflammatory AIT process.

- Abstract
Graves’ hyperthyroid patients were treated daily for 10 days with 1 g sodium ipodate, a cholecystographic agent which exerts a blocking effect on the peripheral conversion of T4to T3, or with 12 drops of saturated solution of potassium iodide (SSKI). Serum concentrations of free T4(FT4) and free T3(FT3) were measured before, during and 5 and 10 days after the administration of each drug. Sodium ipodate treatment induced a rapid decrement of serum FT4concentrations which declined from 48.9 ± 6.6 pg/ml to 26.0 ± 2.7 pg/ml. In these patients serum FT3concentrations declined from 12.4 ± 2.0 pg/ml to 2.5 ± 0.4 pg/ml. Ten days after sodium ipodate withdrawal, serum FT4and FT3concentrations returned to baseline values. In patients treated with SSKI serum FT4concentrations declined from 51.1 ± 8.8 pg/ml to 11.3 ± 1.4 pg/ml and FT3 from 15.7 ± 2 pg/ml to 2.6 ± 0.3 pg/ml. Moreover, after therapy interruption serum free thyroid hormone concentrations returned to baseline values in these patients. Serum FT4pattern during the study was not different between the two groups of subjects whereas serum FT3concentrations were significantly lower in patients treated with sodium ipodate. These findings indicate that SSKI and sodium ipodate are effective in inducing a rapid decrement of serum free thyroid hormone concentrations. Therefore the employment of these drugs may be useful in the treatment of patients with thyroid storm and those undergoing thyroidectomy.

- Abstract
In order to determine whether dopamine plays a role in the control of neuropituitary function in pregnant women during labour, blood levels of nicotine (NSN)- and estrogen (ESN)-stimulated neurophysins were measured in 119 women treated orally with placebo (n = 59, control group) or 5 mg bromocriptine, a potent dopaminergic receptor agonist (n = 60, experimental group). Serum samples were taken before drug ingestion (basal sample) and at delivery. The serum basal concentrations of NSN and ESN were similar in both groups of pregnant women in labour. At delivery, serum ESN levels were similar in all women regardless of the treatment, whereas NSN concentrations were significantly lower in the bromocriptine-treated women than in those who were given placebo.In additional experiments the effect of 5 mg bromocriptine on the serum concentrations of NSN and ESN was tested for 6 hours after drug ingestion in 10 healthy, non-pregnant women and in 8 women in the 3rd trimester of pregnancy. Bromocriptine did not modify the circulating levels of NSN and ESN in either of these 2 groups of women.Since NSN and ESN are thought to be associated with vasopressin and oxytocin, respectively, these results indicate that in non-pregnant women and in pregnant women during late pregnancy dopaminergic stimulation with a dopaminergic receptor agonist does not inhibit the release of either vasopressin or oxytocin during rest. In contrast, dopaminergic receptor stimulation appears to play an inhibitory role in the regulation of vasopressin, but not oxytocin secretion in pregnant women in labour.

- Abstract
We tested sera and purified immunoglobulin (Ig) fractions from patients with autoimmune thyroid disorders (AITD), with and without ophthalmopathy, and normal subjects, for the presence of antibodies reactive with eye muscle membrane antigens in an optimized enzyme-linked immunosorbent assay (ELISA). We found no correlation between ELISA results and the presence or severity of ophthalmopathy in patients with AITD for either serum or Ig, and there were no significant differences between the mean values (± SE) for the three groups (AITD with ophthalmopathy, AITD without ophthalmopathy and normals) for either serum or Ig. In contrast Ig from 8 of 19 (45%) patients with thyroid-associated ophthalmopathy reacted with a 64 kDa eye muscle membrane antigen in SDS-polyacrylamide gel elec-tropohoresis and Western blotting, while tests were positive in only one of the 8 patients with AITD without eye disease and in none of the 8 normal subjects. The presence of antibodies to a 64kDa antigen in immunoblotting did not correlate with the levels of antibodies measured in ELISA. We conclude that the ELISA, incorporating crude membrane fractions as antigen, is not useful as a clinical test for eye muscle autoantibodies.

- Abstract
The long-acting somatostatin analogue SMS 201-995 has been used efficaciously in the therapy of metastatic carcinoid tumor, vasoactive intestinal peptide producing islet cell carcinoma, acromegaly, and TSH secreting pituitary tumors. We report the development of a gallstone in a patient treated for 23 months with a long acting somatostatin analogue for a metastatic carcinoid tumor. Symptomatic improvement and a reduction in the urinary excretion of 5-hydroxyin-doleacetic acid occurred. There was no evidence of a gallstone on ultrasound and CT scan of the abdomen prior to somatostatin therapy. A progressively enlarging, asymptomatic gallstone developed during therapy.

- Abstract
Evaluation of thyroid status by measurement of free thyroid hormone concentrations seems particularly helpful in conditions with altered serum binding proteins. In pregnancy, a condition of increased thyroxine binding globulin, serum free thyroxine (FT4) and free triiodothyronine (FT3) concentrations have been reported to be normal, increased or decreased. In the present study we have measured serum total and free thyroid hormone concentrations in pregnant women, their newborns and nonpregnant women. Serum FT4 and FT3 concentrations have been measured with 10 different commercially available kits and the results obtained have been compared. Serum total thyroid hormone concentrations in pregnant women were significantly higher than in their newborns and in nonpregnant women. Maternal serum FT4 concentrations measured with the different kits were always significantly lower than values in nonpregnant women. Furthermore, with one kit, the mean maternal serum FT4 concentration was below the normal range and with many kits, a large number of maternal serum samples had serum FT4 concentrations below the normal range. With all kits, except two, neonatal serum FT4 concentrations were higher than values in their respective mothers and, in general, lower than values in nonpregnant women. Serum FT3 concentrations in nonpregnant women were in the normal range, except with one kit, in which the mean serum FT3 concentration was below the normal range. Serum FT3 concentrations in newborns resulted markedly lower than in parturient and in non pregnant women. With almost all kits, serum FT3 values were below the normal range in many maternal samples. With one kit, maternal serum FT3 concentrations resulted higher than in nonpregnant women, whereas with the other kits serum FT3 concentrations were lower. Despite the variability of serum FT4 and FT3 concentrasions, serum TSH concentrations in pregnant women and their newborns, resulted in the normal range. These findings suggest that many kits for the measurement of serum free thyroid hormone concentrations do not seem adequate to evaluate the real thyroid status of pregnant women and newborns. Therefore, in these physiological conditions the measurement by commercial kits of serum FT4 and FT3 concentrations do not offer a real advantage in respect to serum total thyroid hormone determination.

- Abstract
To study the effect of thyrotropin-releasing hormone (TRH) and somatostatin (SRIF) on prolactin (PRL) secretion in at term human fetus these peptides have been administered to at term pregnant women during labor. Evidence has been reported that TRH and SRIF cross the placental barrier and affect the secretion of pituitary hormones. 400 μg TRH were administered to 37 pregnant women. As control 11 women received saline. In cord blood (CB) of neonates whose mothers received TRH CB PRL concentration was not different from those treated with saline, with values ranging between 192 ± 18 and 342 ± 48 ng/ml. 500 μg cyclic SRIF diluted in saline was infused over a period of 30 min in 55 women. Control subjects were infused with saline. At birth CB PRL concentration in SRIF treated neonates ranged between 266 ± 32 and 327 ± 48 ng/ml. In neonates whose mothers were treated with saline, CB PRL was 305 ± 31 ng/ml. This value was not significantly different from that in SRI F-treated groups. Our findings suggest that in at term human fetus TRH does not stimulate PRL secretion probably because fetal pituitary secretes PRL at maximal releasing activity. Furthermore SRIF administration does not have any effect on fetal PRL secretion as consistently observed in adults.

Robuschi, G., Emanuele, R., d’Amato, L., Salvi, M., Dall’Aglio, E., Gardini, E., Fatone, M., Foscolo, S., Gnudi, A., and Roti, E.
- Abstract
To investigate the effect of metoclopramide (MET), a dopaminergic antagonist drug, on serum PRL concentration in maternal and cord blood (CB) serum, the drug was injected in 94 at term pregnant women whereas 28 mothers received saline. Maternal serum (MS) samples were obtained before MET injection and at the parturition time. According to the interval of time between MET administration and birth, MS specimens were grouped in 7 groups. CB was obtained from neonates whose mothers were injected with saline, group 0 and from newborns whose mothers were treated with MET, groups 1 to 7. In the 7 groups of women the mean PRL concentration before MET ranged between 307 and 439 ng/ml. After MET injection a significant increase has been observed in all groups with a minimum and maximal mean value of 639 and 931 ng/ml. The highest net increment of PRL has been measured ingroup 1 sampled at 5 to 30 minutes after MET. CB PRL concentration in group 0, saline treated, was not different from the values measured in group 1 to 7, treated groups, with a range between 504 and 703 ng/ml. These findings suggest that maternal lactotropes are still responsive to MET. On the opposite, fetal pituitary does not release PRL after MET injection probably because PRL secretory activity is maximal or because the dopaminergic receptors’ system is still immature.

- Abstract
We have evaluated the occurrence of postpartum thyroid dysfunction (PPTD) in a group of 372 women residing in area of mild iodine deficiency. Thyroid function and autoimmune status were evaluated by means serum T4, T3, TSH measurement and detecting the presence of positive antithyroglobulin antibodies (AbTg), antimicrosomal antibodies (AbM) and thyroid-peroxidase antibodies (AbTPO) titers in women at parturition, at 1, 3, 6 and 12 months postpartum. New onset transient hypothyroidism occurred in 6.4% of women whereas transient thyrotoxicosis in only 1.8% of women. Transient hypothyroidism was not preceded by thyrotoxicosis as indicated by thyroid function tests and serum Tg concentrations. At parturition, the positivity of AbM and AbTPO titers and the presence of goiter appeared to be a risk factors for the development of PPTD.

15. Selenium administration does not cause thyroid insufficiency in subjects with mild iodine deficiency and sufficient selenium intake
- Author

Roti, Elio, Minelli, R., Gardini, E., Bianconi, L., Ronchi, A., Gatti, A., and Minoia, C.
- Abstract
Selenium is a trace element essential for the activity of type I 5′-deiodinase which converts thyroxine (T4) to 3,5,3′-triiodothyronine (T3). In iodine deficient hypothyroid children at low selenium dietary intake the supplementation of selenium induced a significant decrement of serum FT4 and T4 concentrations and an increase of serum TSH concentrations. Since in western countries selenium tablets begin to be largely consumed as a diet integrator, we have administered 100 μg/day of selenium as selenium methionine to 8 euthyroid female subjects with a positive iodine-perchlorate discharge test who had a previous episode of subacute or postpartum thyroiditis. We have studied subjects with positive iodine-perchlorate discharge test since the test indicates the existence of a subtle defect of thyroid hormone synthesis and therefore these subjects are prone to develop thyroid dysfunction. In contrast to previous findings in hypothyroid children at low iodine and selenium dietary intake, the supplementation of selenium did not decompensate thyroid hormone synthesis of euthyroid subjects with reduced thyroid iodine organification. The lack of ny effect of selenium on thyroid hormone synthesis even in subjects with subtle thyroid hormone synthesis defect may be due to the fact that these subjects had a sufficient selenium dietary intake before selenium supplementation and an only marginally reduced dietary iodine intake.

- Abstract
OBJECTIVE To determine the effects of pharmacological quantities of iodide (SSKI) on thyroid function in euthyroid patients previously treated with recombinant interferon-alpha (rIFN-alpha) for chronic viral hepatitis B and C (HCV), a cytokine which may induce thyroid dysfunction. DESIGN Thyroid function tests were carried out in 16 euthyroid patients, 8 of whom had previously developed thyroid dysfunction during rIFN-alpha therapy for HCV, before, during and after the administration of 10 drops of saturated solution of potassium iodide (SSKI) (=~350 mg iodide). PATIENTS All 16 patients had been treated in the past with rIFN-alpha for HCV. Eight patients had developed rIFN-alpha induced abnormalities in thyroid function (5 inflammatory thyrotoxicosis, 1 Graves' disease, and 2 impaired thyroid organification of iodide) and 8 had not developed thyroid dysfunction. MEASUREMENTS After baseline serum free T4 (FT4) and free T3 (FT3) concentrations, basal and TRH stimulated TSH concentrations, and TSH-receptor (TSH-R-Ab) and thyroid peroxidase (TPO-Ab) antibodies were measured, 10 drops saturated solution of potassium iodide (SSKI, =~350 mg iodide) were given daily for 60 days and the above parameters assessed during and after SSKI was discontinued. RESULTS Five of 8 patients with a previous history of rIFN-alpha induced thyroid dysfunction developed mild iodide induced abnormalities of thyroid function (subclinical hypothyroidism (slightly elevated basal and TRH stimulated serum TSH concentrations with normal serum FT4 and FT3 concentrations) or hyperthyroidism) compared with the 8 patients who had no previous evidence of thyroid dysfunction during rIFN-alpha therapy. CONCLUSIONS In view of the present observations, it is prudent to avoid the administration of excess iodine to euthyroid subjects with a previous episode of thyroid dysfunction during rIFN-alpha therapy, adding a new group of patients susceptible to iodine induced thyroid disease.

- Abstract
Abstract. The present study was undertaken in order to establish whether muscarinic cholinergic receptors are involved in the anomalous GH response to GnRH in men with insulin-dependent diabetes mellitus and in male patients with major depression. For this purpose, 16 male diabetics, 18 depressed men and 9 normal controls were tested with GnRH (25 µg iv) with and without previous treatment with the muscarinic cholinergic receptor blocker pirenzepine (40 mg iv 10 min before GnRH). Additional experiments with TRH (200 µg iv 10 min after pirenzepine) were performed in the same subjects and used for comparison between responders to TRH and GnRH. The administration of GnRH stimulated GH release in 12 out of the 16 diabetics and in 8 out of the 18 depressed patients, but not in the normal controls. Control and diabetic non-responders to GnRH did not respond to TRH. In contrast, all diabetic responders to GnRH, except 2, showed paradoxical GH responses to TRH. All depressed responders to GnRH and 3 of the non-responders, were responsive to TRH. The pattern and magnitude of the secretory responses to TRH and GnRH were similar in depressed and diabetic patients. When the effects of GnRH and TRH were restudied in the presence of pirenzepine, neither GnRH nor TRH enhanced the serum concentrations of GH in any patient. These data indicate that a muscarinic cholinergic mechanism is involved in the anomalous responses of GH to GnRH and TRH in diabetic men and in male patients affected by major depression.

Minelli, R., Gardini, E., Bianconi, L., Salvi, M., and Roti, Elio
- Abstract
In a patient chronically treated with amiodarone, subclinical iodine-induced hypothyroidism occurred as a result of excess iodine released from the amiodarone molecule. The patient was maintained on amiodarone and developed thyrotoxicosis as a result of a destructive process into the thyroid follicles. Amiodarone was withdrawn and methylprednisolone and methimazole treatment was started with resolution of the thyrotoxic phase. Months later, off therapy, the patient developed subclinical hypothyroidism. This is the first description of hypo-and hyperthyroidism in the same patient caused by amiodarone therapy. This unusual observation suggests that patients treated with amiodarone are at risk to develop hyperthyroidism even if they show laboratory findings consistent with hypothyroidism.
