Screening of geriatric patients for thyroid dysfunction with thyrotropin-releasing-hormone test, sensitive thyrotropin and free thyroxine estimation

Hospitalized geriatric patients (N = 354) from an iodine-deficient area were screened with sensitive thyrotropin (TSH), free and total thyroxine (FT4, T4) and total triiodothyronine (T3) to determine the occurrence rate of clinical and subclinical thyroid dysfunction. The diagnostic value of the tests was compared to each other and to that of the thyrotropin-releasing-hormone test (TRH-test) in order to find the optimal first line screening test in geriatric patients. Clinical hyperthyroidism was found in 13, subclinical hyperthyroidism in 10, overt hypothyroidism in 6 and subclinical hypothyroidism in 8 cases. 20.6% of the patients were euthyroid but had subnormal TSH response to TRH, as a sign of possible thyroid autonomy. The low occurrence rate of clinical thyroid disorders (4.8%) does not justify the screening of geriatric patients in general, but the high probability of thyroid autonomy makes reasonable the investigation of every geriatric patient before iodine administration. Suppressed basal TSH and high FT4 were found to be both sensitive and specific in diagnosing clinical hyperthyroidism, but the predictive value was insufficient; elevated T4 and T3 are specific, but not sensitive. Basal TSH is sensitive, specific and has a good predictive value in diagnosing euthyroidism, whereas normal T4, FT4 or T3 are not specific enough for euthyroidism. Basal TSH is better as a first line test of thyroid function than FT4. A normal basal TSH confirms euthyroidism by itself. Other tests (TRH test, T4, FT4, T3) are necessary to elucidate the clinical importance of a subnormal or suppressed basal TSH.     

Thyroid functions in patients with various chronic liver diseases

In order to clarify an alteration in thyroid functions in patients with chronic liver diseases, serum total and free thyroxine (T4, FT4), total and free triiodothyronine (T3, FT3), total reverse T3 (rT3), thyrotropin (TSH), thyroxine-binding globulin (TBG) concentrations, and T3 uptake (T3U) were measured by radioimmunoassays in 53 patients with chronic hepatitis (CH), 24 patients with compensated liver cirrhosis (LC), 17 patients with hepatocellular carcinoma associated with LC (HCC), and 40 normal subjects. Serum T4, T3, and rT3 in CH, and serum rT3 in HCC were significantly increased, while serum T4 in LC and serum T3 in HCC were significantly decreased. Serum TBG was increased and T3U was decreased in these patients. Serum TBG in CH and LC correlated positively with transaminase, and inversely with prothrombin time. FT4 and T4/TBG ratios in CH and LC and FT3 and T3/TBG ratios in LC and HCC were significantly decreased. Although T4/TBG ratios in HCC and T3/TBG ratios in CH were significantly decreased, FT4 in HCC and FT3 in CH were not decreased. The ratio of rT3/T3 in CH and LC correlated with various liver function tests. FT3 in LC and HCC correlated inversely with BSP (45') and positively with KICG. No differences in serum TSH values were found between chronic liver diseases and normal subjects. From these results, it was concluded that the thyroid functions in patients with chronic liver diseases were affected by the decrease in serum thyroxine, elevated serum TBG, the degree of which is in proportion to that of the liver cell damage, and impaired peripheral conversion of T4 to T3, the degree of which is in proportion to that of the hepatic dysfunction.     

Behavior of thyroid hormones and TSH in chronic active hepatitis

The authors studied total and free circulating thyroid hormones, rT3, TBG and TSH behaviour on chronic liver disease in 11 subjects with cirrhosis of the liver with ascites(C.E.) and in 6 subjects with chronic active hepatitis (E.C.A.) in comparison with 15 healthy and euthyroid controls. Serum T3,FT3,T4 and FT4 levels were decreased significantly and serum rT3 values increased significantly both in the subjects with C.E. and in patients with E.C.A. Moreover no significantly changes of TSH and TBG levels has been found in 3 groups studied. These data suggest that the alteration of circulating thyroid hormones in chronic liver disease, may represent a compensatory way of reducing the patient's metabolic requirements.     

The pituitary-thyroid axis in patients with pituitary disorders

The pituitary-thyroid axis of 12 patients, exposed to transsphenoidal pituitary microsurgery because of nonfunctioning adenomas (6), prolactinomas (3) and craniopharyngioma (1), or to major pituitary injury (1 apoplexy, 1 accidental injury), was controlled more than 6 months following the incidents. The patients did not receive thyroid replacement therapy and were evaluated by measurement of the serum concentration of thyroxine (T4), 3,5,3'-triiodothyronine (T3), 3,3',5'-triiodothyronine (rT3), T3-resin uptake test and thyrotropin (TSH, IRMA method) before and after 200 micrograms thyrotropin releasing hormone (TRH) iv. The examination also included measurement of prolactin (PRL) and cortisol (C) in serum. Apart from 1 patient with pituitary apoplexy all had normal basal TSH levels and 9 showed a significant TSH response to TRH. Compared to 40 normal control subjects the 12 patients had significantly decreased levels of T4, T3 and rT3 (expressed in free indices), while the TSH levels showed no change. Five of the patients, studied before and following surgery, had all decreased and subnormal FT4I (free T4 index) after surgery, but unchanged FT3I and TSH. The levels of FT4I were positively correlated to both those of FT3I and FrT3I, but not to TSH. The TSH and thyroid hormone values showed no relationship to the levels of PRL or C of the patients exposed to surgery. It is concluded that the risk of hypothyroidism in patients exposed to pituitary microsurgery is not appearing from the TSH response to TRH, but from the thyroid hormone levels.     

Variations in the serum levels of thyroid hormones and TSH after intake of a dose of L-thyroxine in euthyroid subjects and in adequately-treated hypothyroid patients

The aim of the present study was to determine whether the temporary variations in blood thyroid hormone levels secondary to a therapeutic dose administration of L-thyroxine observed in adequately treated hypothyroid patients also occur in spontaneously euthyroid subjects under analogous conditions. Serum levels of T3, T4, FT3, FT4 and TSH were measured over 6 hours following a single oral administration of L-thyroxine (dosage 85 mcg/mq body surface area) in a group of 18 euthyroid volunteers and 8 hypothyroid patients adequately compensated with replacement therapy. In the euthyroid subjects there was a significant increase in T4 and a significant fall in TSH values at 60', while a significant decrease in FT3 and FT4 as compared to initial values was observed at 120'. In the treated hypothyroid patients serum T3 and T4 increased at 120', while FT4 concentrations, already significantly higher at 120', still remained higher than initial levels at 360'. The different behaviour of the hypothyroid patients, in spite of being compensated with therapeutic doses of L-thyroxine, reflects the persistence of a thyroid-metabolic condition substantially different to the physiological feature, which appears to be realized by means of a reduced iodothyronine clearance and a lower sensitivity in TSH feedback.     

Long-term intramuscular administration of thyrotropin-releasing hormone tartrate in patients with cerebrovascular disease: effects on the pituitary-thyroid axis.

We studied the effects of long-term (30 days) refracted daily intramuscular administration of 4 mg TRH tartrate (TRH-T) on the pituitary-thyroid axis in 20 euthyroid patients affected by cerebrovascular disease (CVD). All subjects were assayed for T4, T3, FT4, FT3, TSH and TBG plasma levels before treatment (D0), after 15 and 30 treatment days (D15, D30), and after a 15-day washout (D45). In addition, TSH response to 200 micrograms intravenous TRH was assessed at D0, D30 and D45. We observed a significant increase in T4, FT4 and FT3 levels in the face of decreased TSH concentrations. A blunted TSH response to TRH bolus persisted at D30. These data demonstrate that the down-regulation mechanism may be partially overcome in vivo when thyrotrophs are chronically exposed to pharmacological TRH-T doses and that TSH pattern is mainly due to the negative feedback of thyroid hormones, even though pituitary TSH reserves may become depleted. Furthermore, prolonged TRH-T administration does not produce hyperthyroidism in euthyroid CVD patients.     

Unusual features of neonatal thyroid function in small-for-gestational-age lambs. Origin of plasma T4 and T3 deficiencies

Thyroid function was studied in small for gestational age (SGA) or control newborn lambs. Neonatal changes in plasma concentrations of TSH, T3, rT3, total and free T4 were monitored, and thyroid scintigraphs were performed. Responsiveness of the hypothalamic-pituitary-thyroid axis to cold exposure and TRH or TSH administration was assessed. In addition, T4 and T3 kinetic studies were performed. In agreement with results obtained in babies, plasma T3, total T4 and free T4 concentrations were depressed in low birth weight animals, whereas TSH and rT3 levels were not affected. Thyroid size expressed relatively to the body weight was higher in SGA animals, thus suggesting that a partial compensation for low thyroid hormone levels had occurred during the fetal life. Plasma TSH and T4 concentrations increased by a same extent after exposure to cold and TRH or TSH administration in SGA and control lambs; however, the rise in T3 levels was depressed in the former in all stimulation tests. T3 and T4 production rates were similar in the two experimental groups. In SGA lambs, the metabolic clearance rate and the total distribution space of these two hormones were significantly increased; the fast T3 pool was higher, and the slow T3 pool lower than in control animals. All these results demonstrate that, despite low circulating thyroid hormone concentrations, SGA lambs are not hypothyroid. An increased T4 and T3 storage in the extravascular compartment is probably the major factor involved in the occurrence of this plasma deficiency.(ABSTRACT TRUNCATED AT 250 WORDS)

Analysis of overall pathophysiological relationships between serum levels of TSH and thyroid hormones using a large laboratory database

Factors associated with the basal level of serum thyrotropin (TSH) were analyzed over a wide range of pathophysiological conditions by means of a large laboratory database on thyroid function. When data were analyzed two-dimensionally, serum TSH showed significant inverse correlations with total triiodothyronine (T3), free T3 index (FT3I), total thyroxin (TT4) and free T4 index (FT4I) in the order of increasing intensity. The three-dimensional analysis, however, revealed that 1) total hormone levels were actually unrelated to serum TSH when the levels of free hormone indices were held constant, 2) the relation between FT3I and TSH became obscure when the influence of FT4I was similarly removed. On the other hand, 3) the relation of FT4I with TSH was unaffected by the level of FT3I. These results suggest that free T4 is the main determinant of the serum TSH level. This study also implies that it is possible to use large amounts of laboratory data to elucidate the overall profile of a given patho-physiological system, whose structure is only partially revealed by conventional clinical or animal studies.     

Visfatin Levels in Subclinical Hypothyroidism

Alterations in thyroid function are associated with changes in body weight, metabolism, and low-grade inflammation abnormal thyroid function may be associated with disturbances in the production of adipokines also. Although there have been studies showing changes in visfatin levels in thyroid dysfunction, exact relationship between them was still unclear. Our aim was to evaluate serum concentrations of visfatin in patients with subclinical thyroid dysfunction before and after normalization of thyroid function tests. The study included 43 patients (mean age 50.1 ± 10.6 years) with subclinical hypothyroidism. Serum insulin, visfatin, TSH, free T4 (FT4) and free T3 (FT3) levels of subjects were analyzed. Visfatin levels were measured in all patients before starting therapy and after normalization of thyroid function. Serum visfatin levels of subclinical hypothyroid patients were 0.99 ± 0.45 and they were similar after normalization of thyroid function (p = 0.394). Serum visfatin levels were negatively correlated with FT4 levels before treatment (r = ?0.329 p < 0.05). There was no significant correlation between serum levels of visfatin and the serum levels of TSH and FT3. Serum visfatin levels did not correlate with insulin, fasting blood glucose, total cholesterol, HDL cholesterol, LDL cholesterol and triglyceride levels. In this study, it was shown visfatin levels did not change after replacement therapy in patients with subclinical hypothyroidism. Subclinical hypothyroid state may be an earlier stage regarding the changes of adipocytokines specifically the visfatin secretion as seen in overt hypothyroidism.

Anomalies in thyroid function in children with trisomy 21

Thyroid function of 60 children with Down (DS) aged 3 months to 16 years was studied by evaluation of serum concentration of ultra-sensitive thyroid stimulating hormone (TSH), free T4 and T3 (FT4, FT3), total T4 and T3 (T4 and T3) and reverse T3 (rT3). Each DS child was matched to a control of the same age. The concentration of TSH was increased in DS children while the concentration of rT3 of the DS children was significantly decreased compared to the controls as was the ratio rT3/TSH. These results showed that thyroid function of DS children is abnormal.     

Effect of subclinical hypothyroidism and obesity on whole-body and regional bone mineral content

OBJECTIVE: The present investigation was aimed to evaluate the effect of subclinical hypothyroidism and obesity on bone mineral content (BMC) in different body segments. METHODS: Thirty-two premenopausal women (age: 37 +/- 9.9 years), with a wide range in body mass index (BMI), were studied. Subclinical hypothyroidism was defined by a basal TSH > or = 4 microU/l and/or a TRH-stimulated peak > or = 30 microU/l. For each subject, weight, height, BMI (weight/height(2)) and the waist/hip ratio were measured. Total BMC, total bone mineral density (BMD), leg BMC, leg BMD, trunk BMC, trunk BMD, arm BMC and arm BMD were determined using dual-energy X-ray absorptiometry. Thyroid function (basal and TRH-stimulated TSH, free T(3) and free T(4)) were determined from fasting blood samples for all subjects. RESULTS: Anova was conducted within all the groups to observe the effect of thyroid status and/or obesity on BMC and BMD. There was no statistical difference for age. Total BMC was affected by obesity (p < 0.05) but not by thyroid status, BMD of the legs was significantly influenced both by thyroid function and obesity (p < 0.01); total BMD was affected by hypothyroid status (p < 0.05). A direct relationship between leg BMD and TSH was demonstrated. CONCLUSION: Subclinical thyroid hypofunction and obesity seem to affect BMD differently in the body segments. An influence of gravitational force seems necessary in order to make evident the effect of subclinical hypothyroidism on bone. A condition of subclinical hypothyroidism should be considered when evaluating subjects for osteoporosis, since a BMD measured at the femoral neck may induce underestimation of initial osteoporosis.     

Thyroid hormone levels during a 3-week professional road cycling competition

AIMS: The aim of this investigation was to examine the thyroid hormone levels of professional cyclists during a 3-week stage competition (Vuelta a Espa?a 1998). METHODS: The study population was made up of 16 male cyclists from two world-leading professional teams. Four blood samples were drawn (between 07:00 and 09:00 a.m.) from each participant before and at the end of the 1st, 2nd and 3rd weeks of competition. 3,5,3'(-Triiodothyronine (T(3)), free T(3) (FT(3)), thyroxine (T(4)), free T(4) (FT(4)) and thyroid-stimulating hormone (TSH) were determined in each blood sample by radioimmunoassay. RESULTS: Serum T(4), FT(4) and FT(3) levels showed a significant increase (p < 0.05) by the last week of competition while concentrations of TSH and T(3) remained unchanged. CONCLUSION: In conclusion, 3 weeks of competition provokes changes in basal thyroid hormone concentrations in professional road cyclists.     

Abnormalities in pituitary thyroid axis function tests in patients with paroxysmal supraventricular arrhythmias

The study was carried out on 60 consecutive patients (23 males and 37 females) aged between 20 and 83 years (means +/- SD, 40.7 +/- 16) who arrived at our Cardiologic Unit with paroxysmal supraventricular arrhythmias (PSVA) including junctional paroxysmal tachycardia (n = 32), atrial fibrillation (n = 13), atrial flutter (n = 1), premature beats (n = 13) and with no obvious cardiovascular causes. Serum thyroxine and triiodothyronine were normal in all patients and thyroid scintiscan revealed normal shape and size thyroids without autonomously functioning nodule(s). Thyrotropin (TSH) response to thyrotropin releasing hormone (TRH) was normal in 44 subjects in whom normal serum free T4 (FT4) and free T3 (FT3) levels were measured. Six patients with normal FT4 and FT3 levels did not respond to TRH. Abnormalities in thyrotropin response to TRH were observed in 10 patients all exhibiting increased FT4 or also FT3 levels. Among these, 5 patients did not respond to TRH, whereas the remaining 5 exhibited a blunted TSH response to TRH. These results suggest that only in a small proportion (5/60) of consecutive patients with PSVA it is possible to recognize a status of "occult thyrotoxicosis" on the basis of the combined evaluation of free thyroid hormones and TSH response to TRH.     

The Association of Thyroid Hormones and Tsh with the Metabolic Syndrome in Euthyroid Taiwanese Individuals

Objective: There are conflicting studies in euthyroid males and females regarding associations between thyroidrelated hormones and parameters of the metabolic syndrome (MetS). We investigated the association between serum thyroid hormones and thyroid-stimulating hormone (TSH) concentrations and MetS in euthyroid men and women.Methods: Taiwanese subjects aged 20 to 65 years who had undergone a voluntary health examination at a preventive examination agency in Taipei were enrolled in this cross-sectional study. The definition of MetS was suggested by the Bureau of Health Promotion, Department of Health, Taiwan. Euthyroidism was defined as TSH and free thyroxine (FT4) levels within the normal reference ranges while not taking any thyroid medication. We conducted multiple logistic regression to identify the ability of serum triiodothyronine (T3), FT4, and TSH concentrations to identify the relative risk for the presence of MetS and components of the MetS in euthyroid Taiwanese individuals.Results: A total of 8,207 Taiwanese subjects (mean age: men, 45.3 ± 9.9 years; women, 43.5 ± 9.3 years) were enrolled in this study. A total of 1,672 subjects (20.4%) were defined as having MetS; these subjects had significantly higher (P<.0001) mean age (48.4 ± 9.1 years vs. 43.6 ± 10.7 years), prevalence of men (78.7% vs. 53.4%), and smoking (16.8% vs. 11.6%) than those without MetS. The median TSH, FT4, and T3 levels in all subjects were 1.70 mIU/L, 1.41 ng/dL, and 1.20 ng/mL, respectively. Higher T3 and lower FT4 values rather than TSH increased the odds ratio for MetS in men and women after adjusting for smoking and age, particularly for the association of T3 and MetS in women (uppermost quartile versus lowermost quartile: odds ratio, 2.4; 95% confidence interval, 1.6 to 3.5; P for trend <.0001).Conclusion: In euthyroid Taiwanese men and women, relatively high serum T3 concentrations was most strongly associated with the presence of the MetS; relatively low serum T4 was less strongly related, and serum TSH levels were not associated with the MetS. It is not known if the relationship of serum T3 and T4 to the MetS is causal.Abbreviations:BMI = body mass indexFT4 = free thyroxineMetS = metabolic syndromeOR = odds ratioT3 = triiodothyronineTSH = thyroid-stimulating hormoneWC = waist circumference     

Serum thyroid hormone profile and trace elements in children receiving valproic acid therapy: A longitudinal and controlled study

Valproic acid (VPA) may affect thyroid hormone profile, causing alteration in serum trace elements concentrations. The aim of this study was to prospectively investigate this relationship in children receiving VPA monotherapy for a period up to 6 months. Serum thyrotropin (TSH), free thyroxine (FT4), free triiodothyronine (FT3), thyroxine (T4), triiodothyronine (T3), thyroglobuline (TG), selenium (Se), zinc (Zn), and copper (Cu) levels were evaluated at baseline and at the 6th month in all the patients and in the control group. The mean Cu concentration in the 6th months of VPA therapy was significantly lower than that of the control group. TSH level was significantly increased in the patient group whereas FT4 was significantly decreased. The mean TSH level in the 6th month of VPA therapy was significantly higher than that of the control group, whereas mean T4 level was significantly lower. The Cu level in the 6th months of VPA therapy was positively correlated with T4 level. Δlog Cu and ΔTSH were negatively correlated. This study suggests that the alteration in the serum thyroid hormone profile during VPA therapy may result from the reduction in serum Cu levels.     

Selenium Status Is Positively Associated with Bone Mineral Density in Healthy Aging European Men

ObjectiveIt is still a matter of debate if subtle changes in selenium (Se) status affect thyroid function tests (TFTs) and bone mineral density (BMD). This is particularly relevant for the elderly, whose nutritional status is more vulnerable.ResultsThe overall Se status in our population was low normal with only 0.5% (2/387) of subjects meeting the criteria for Se deficiency. SePP and Se levels were not associated with thyroid stimulating hormone (TSH), free thyroxine (FT4), thyroxine (T4), triiodothyronine (T3) or reverse triiodothyronine (rT3) levels. The T3/T4 and T3/rT3 ratios, reflecting peripheral metabolism of thyroid hormone, were not associated with Se status either. SePP and Se were positively associated with total BMD and femoral trochanter BMD. Se, but not SePP, was positively associated with femoral neck and ward''s BMD. Multivariate linear analyses showed that these associations remain statistically significant in a model including TSH, FT4, body mass index, physical performance score, age, smoking, diabetes mellitus and number of medication use.ConclusionOur study demonstrates that Se status, within the normal European marginally supplied range, is positively associated with BMD in healthy aging men, independent of thyroid function. Thyroid function tests appear unaffected by Se status in this population.     

Human cold air habituation is independent of thyroxine and thyrotropin.

Thyroxine (T4) is required in species possessing brown adipose tissue (BAT) for the maintenance of cold tolerance and adaptation. In humans, who possess negligible quantities of BAT, the importance of T4 has not been demonstrated. We studied the effects of decreased serum T4 and thyrotropin (TSH) on human cold habituation after repeated cold air exposures. Eight men (T3+) received a single daily dose of triiodothyronine (T3; 30 micrograms/day), and another eight men (T3-) received a placebo. All 16 normal thyroid men underwent a standardized cold air test (SCAT) under basal conditions in January and again in March after eighty 30-min 4.4 degrees C air exposures (10/wk). Measurements of basal metabolic rate (BMR), O2 consumption (VO2), mean arterial pressure (MAP), plasma norepinephrine (NE), serum TSH, free and total T4, and free and total T3 were repeated before and after 8 wk of exposure. TSH, free T4, and total T4 were 50% lower for T3+ than for T3- subjects. Total and free T3 were not different between groups. BMR was unchanged after habituation, whereas the cold-stimulated VO2, MAP, and NE were significantly reduced for all subjects in March. The relationship between VO2 and NE (r2 = 0.44, P less than 0.001) during the initial SCAT was unchanged with habituation. We suggest that human cold habituation is independent of major changes in circulating T4 and TSH.
