AB  - Introduction: Nickel (Ni) is one of the well-known toxic metals found in the environment. However, its influence on thyroid function is not explored enough. Hence, the aim of this study was to analyse the potential of Ni to disrupt thyroid function by exploring the relationship between blood Ni concentration and serum hormone levels (TSH, T4, T3, fT4 and fT3), as well as the parameters of thyroid homeostasis (SPINA-GT and SPINA-GD) by using correlation analysis and Benchmark (BMD) concept. Methods: Ni concentration was measured by ICP-MS method, while CLIA was used for serum hormone determination. SPINA Thyr software was used to calculate SPINA-GT and SPINA-GD parameters. BMD analysis was performed by PROAST software (70.1). The limitations of this study are the small sample size and the uneven distribution of healthy and unhealthy subjects, limited confounding factors, as well as the age of the subjects that could have influenced the obtained results. Results and discussion: The highest median value for blood Ni concentration was observed for the male population and amounted 8,278 µg/L. Accordingly, the statistically significant correlation was observed only in the male population, for Ni-fT4 and Ni-SPINA-GT pairs. The existence of a dose-response relationship was established between Ni and all the measured parameters of thyroid functions in entire population and in both sexes. However, the narrowest BMD intervals were obtained only in men, for Ni - SPINA-GT pair (1.36-60.9 µg/L) and Ni - fT3 pair (0.397-66.8 µg/L), indicating that even 78.68 and 83.25% of men in our study might be in 10% higher risk of Ni-induced SPINA-GT and fT3 alterations, respectively. Due to the relationship established between Ni and the SPINA-GT parameter, it can be concluded that Ni has an influence on the secretory function of the thyroid gland in men. Although the further research is required, these findings suggest possible role of Ni in thyroid function disturbances. Copyright

AB  - Purpose: Graves’ orbitopathy (GO) is a specific inflammatory disorder of the orbit characterized by a highly heterogeneous clinical phenotype. The role of thyrotropin receptor antibodies (TSH-R-Ab) has been widely researched, however there is still no evidence that these antibodies have a direct pathogenic role in this pathology. The aim of this study was to examine their relation to the individual clinical features of GO. Methods: Ninety-one consecutive patients with GO were recruited. Total antibody concentration (TSH-R binding inhibitory immunoglobulins, TBII) and their functional activity (stimulating TSH-R-Ab, TSAb) were measured using binding immunoassay and cell-based bioassay, respectively. Results: Both TSAb and TBII levels were significantly associated to the clinical parameters of GO activity. TSAb was a more sensitive serological marker compared to TBII pertaining to eyelid retraction and edema, proptosis, extra-orbital muscle disorders, diplopia, irritable eye symptoms, and photophobia. TSAb, but not TBII, was a significant predictive marker of conjunctival redness, chemosis, caruncle/plica inflammation, eye irritation, and orbital pain, (odds ratio: 3.096, p = 0.016; 5.833, p = 0.009; 6.443, p = 0.020; 3.167, p = 0.045; 2.893, p = 0.032; versus 2.187, p = 0.093; 2.775, p = 0.081; 3.824, p = 0.055; 0.952, p = 0.930; 2.226, p = 0.099, respectively). Neither TSAb nor TBII correlated with the level of proptosis (ρ = 0.259, p = 0.090, and ρ = 0.254, p = 0.104, respectively), however rising TSAb levels were strongly associated to the level of proptosis. Conclusions: TSH-R-Ab were significantly associated with GO’s phenotype. Especially TSAb, as a sensitive and predictive serological biomarker, can improve diagnosis and management of GO.

AB  - Background: Thyrotropin receptor autoantibodies (TSH-R-Ab) are indispensable biomarkers in the laboratory assessment of thyroid-associated orbitopathy (TAO). Clinical sensitivity of three different assays for TSH-R-Ab determination was evaluated in patients with TAO.

Methods: 87 consecutive TAO patients were enrolled and their serum samples analyzed in parallel with three assays. An ECLIA competitive binding and a chemiluminescent bridge immunoassay were used to measure total and bind-ing TSH-R-Ab concentration, while their functional activity was determined using a stimulatory TSH-R-Ab (TSAb) cell-based bioassay.

Results: Compared to the two binding assays (ECLIA p<0.001, bridge p=0.003), the TSAb bioassay was more sensitive pertaining to the positive detection of TSH-R-Ab in TAO patients. No difference (p=0.057) was noted between the ECLIA and bridge assays regarding sensitivity rate. All patients with active and/or moderate-to-severe TAO tested positive in the TSAb bioassay (100% and 100%, respectively), while the positivity rates for bridge and ECLIA binding assays were 89.7% and 82.1% for active TAO, and 90.2% and 86.3% for severe TAO, respectively. Negative predictive values of the bioassay, bridge, and ECLIA assays were 100%, 75%, and 71%, respectively for active TAO, and 100%, 86%, and 71%, respectively for moderate-to-severe TAO. The superiority of the bioassay was most prominent in euthyroid (ET) TAO. Positivity rates of the TSAb bioassay, bridge and ECLIA binding assays were 89.6%, 75%, and 64.6%, respectively for inactive TAO; 86.1%, 69.4%, and 52.8%, respectively for mild TAO; 87.5%, 62.5%, and 12.5%, respectively for euthyroid TAO. The bridge assay correlated better with the ECLIA binding assay (r=0.893, p<0.001), compared to the bioassay (r=0.669, p<0.001).

Conclusions: In patients with TAO of various activity and severity, the TSAb bioassay demonstrates a superior clinical performance compared to both ECLIA and bridge binding assays.
AB  - Uvod: Autoantitela na receptore za tireostimulišući hormon (TSH-R-Ab) su nezamenljivi biomarkeri u laboratorijskoj proceni orbitopatije udru'ene sa štitnom žlezdom (TAO). U radu je procenjena klinička osetljivost tri različita testa za određivanje TSH-R-Ab kod pacijenata sa TAO. Metode: U studiju je ključeno 87 uzastopnih pacijenata sa TAO i njihovi uzorci seruma su analizirani paralelno sa tri testa. Za merenje ukupne i vezujuće koncentracije TSH-RAb korišćeni su ECLIA imunohemijski test kompetitivnog vezivanja i hemiluminiscentni imunohemijski "sendvič" test, dok je njihova funkcionalna aktivnost određena pomoću ćelijskog biološkog testa (bioeseja) za određivanje stimulatornih TSH-R-Ab (TSAb). Rezultati: U poređenju sa dva imunohemijska testa vezivanja (ECLIA P<0,001, "sendvič test" P=0,003), TSAb bioesej se pokazao najosetljivijim u pogledu pozitivne detekcije TSH-RAb kod TAO pacijenata. Nikakva razlika nije detektovana (P=0,057) između ECLIA i "sendvič" testa u pogledu stope osetljivosti. TSAb bioesej je bio pozitivan kod svih pacijenata sa aktivnom i/ili umerenom do teškom TAO (redom 100% i 100%), dok su stope pozitivnosti za sendvič i ECLIA imunohemijski test bile 89,7% i 82,1% za aktivnu TAO, i 90,2% i 86,3% za tešku TAO, redom. Negativne prediktivne vrednosti bioeseja, "sendvič" i ECLIA testova bile su redom 100%, 75% i 71%, za aktivnu TAO, odnosno 100%, 86% i 71%, redom za umerenu do tešku TAO. Superiornost biološke analize bila je najistaknutija kod eutiroidnog oblika (ET) TAO. Stope pozitivnosti TSAb bioeseja, "sendvič" i ECLIA testova vezivanja bile su redom 89,6%, 75% i 64,6%, za neaktivnu TAO; 86,1%, 69,4% i 52,8% za blagu TAO; 87,5%, 62,5% i 12,5% za eutiroidni TAO. "Sendvič" imunohemijski test je bio u boljoj korelaciji sa ECLIA testom kompetitivnog vezivanja (r=0,893, P<0,001), u poređenju sa bioesejom (r=0,669, P<0,001). Zaključak: Kod pacijenata sa TAO različite aktivnosti i težine TSAb bioesej pokazuje superiorne kliničke performanse u poređenju sa obe vrste imunohemijskih testova vezivanja (ECLIA i "sendvič test").

U radu je procenjena klinička osetljivost tri različita testa za određivanje TSH-R-Ab kod pacijenata sa TAO. Metode: U studiju je ključeno 87 uzastopnih pacijenata sa TAO i njihovi uzorci seruma su analizirani paralelno sa tri testa. Za merenje ukupne i vezujuće koncentracije TSH-RAb korišćeni su ECLIA imunohemijski test kompetitivnog vezivanja i hemiluminiscentni imunohemijski "sendvič" test, dok je njihova funkcionalna aktivnost određena pomoću ćelijskog biološkog testa (bioeseja) za određivanje stimulatornih TSH-R-Ab (TSAb). Rezultati: U poređenju sa dva imunohemijska testa vezivanja (ECLIA P<0,001, "sendvič test" P=0,003), TSAb bioesej se pokazao najosetljivijim u pogledu pozitivne detekcije TSH-RAb kod TAO pacijenata. Nikakva razlika nije detektovana (P=0,057) između ECLIA i "sendvič" testa u pogledu stope osetljivosti. TSAb bioesej je bio pozitivan kod svih pacijenata sa aktivnom i/ili umerenom do teškom TAO (redom 100% i 100%), dok su stope pozitivnosti za sendvič i ECLIA imunohemijski test bile 89,7% i 82,1% za aktivnu TAO, i 90,2% i 86,3% za tešku TAO, redom. Negativne prediktivne vrednosti bioeseja, "sendvič" i ECLIA testova bile su redom 100%, 75% i 71%, za aktivnu TAO, odnosno 100%, 86% i 71%, redom za umerenu do tešku TAO. Superiornost biološke analize bila je najistaknutija kod eutiroidnog oblika (ET) TAO. Stope pozitivnosti TSAb bioeseja, "sendvič" i ECLIA testova vezivanja bile su redom 89,6%, 75% i 64,6%, za neaktivnu TAO; 86,1%, 69,4% i 52,8% za blagu TAO; 87,5%, 62,5% i 12,5% za eutiroidni TAO. "Sendvič" imunohemijski test je bio u boljoj korelaciji sa ECLIA testom kompetitivnog vezivanja (r=0,893, P<0,001), u poređenju sa bioesejom (r=0,669, P<0,001). Zaključak: Kod pacijenata sa TAO različite aktivnosti i težine TSAb bioesej pokazuje superiorne kliničke performanse u poređenju sa obe vrste imunohemijskih testova vezivanja (ECLIA i "sendvič test").",

AB  - Mercury (Hg) is one of the most important environmental pollutants with endocrine-
disrupting properties. There is little data from epidemiological studies describing the dose-
response relationship between toxic metal levels and hormone levels. The aim of this study was
to use the nearest neighbor matching analysis to determine the difference in Hg concentration in
healthy/sick subjects with thyroid disease and to use Benchmark modeling to determine the dose-
response relationship between Hg levels in the blood and thyroid-stimulating hormone (TSH) and
thyroid hormones in serum. Blood samples were collected and used for Hg measurement using
the ICP-MS method, and separated serum was used for hormone analysis. The study showed the
existence of a statistically significant difference in Hg levels measured in healthy and sick subjects
and the existence of a dose-response relationship between Hg and all measured hormones, with a
narrow interval obtained for the Hg-TSH pair. The results of this research support the use of the
Benchmark dose approach for the purpose of analyzing data from human studies, and our further
research will be focused on examining the impact of low doses on animal models in order to
determine more precise effects of low doses on the organism.

AB  - Purpose: Graves’ orbitopathy (GO) is an inflammatory autoimmune disorder of the orbit and while the antiphospholipid antibodies (aPL) Abs were associated with the markers of inflammation in the antiphospholipid syndrome (APS), there is no literature that investigate the presence of aPL Abs in GO. We analyzed the prevalence of aPL Abs and the differences between aPL (+) and aPL (−) subgroups of GO patients. Methods: Study included consecutive patients with GO (66 with Graves’ (GD), 10 with Hashimoto (HD), and 8 were euthyroid). Anticardiolipin (aCL) and anti-beta 2glycoprotein I (aβ2gpI) Abs were measured by ELISA. Results: aPL Abs were present in 9/84 (10.71%) patients. The IgM aβ2gpI Abs were present in 8/66 and in 1/10 patients with GD and HD. The IgG aCL Abs were present in one GD patient, and IgM aCL were present in 3/66 GD and in 1/10 patients with HD. In GD group, anti-Tg Abs were in positive correlation with aβ2gpI IgG (p = 0.000) and with anti-TPO Abs (p = 0.016). In HD group, anti-Tg Abs were in positive correlation with IgM aCL (p = 0.042), while anti-TPO Abs were in positive correlation with aβ2gpI IgM (p = 0.014). Conclusion: This study is the first report of the aPL Abs presence in GO patients. The anti-thyroid Abs were linked to aPL suggesting that their presence is not the sole consequence of hyperstimulation of autoreactive B-lymphocytes. Larger studies are necessary to confirm potential cause-effect relations. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

AB  - Physical effort is known to alter the blood levels of many hormones, but there are only a few studies about the biological changes of salivary hormones. The aim of this work was to determine whether salivary testosterone and salivary cortisol levels, measured two weeks before a half-marathon race, relate to running performance in male recreational athletes. A group of eleven male recreational athletes preparing for a half-marathon was included in the study. Saliva for testosterone and cortisol determinations was collected before and immediately after a 15-km training run, two weeks before the half-marathon. Individual official half-marathon times, expressed in hours, were used as a measure of performance. Mean testosterone concentrations were 1.07 +/- 0.33 nmol/l before the run and 0.88 +/- 0.35 nmol/l after the run (p lt 0.05). Mean cortisol concentrations were 12.28 +/- 8.46 nmol/l before the run and 38.08 +/- 19.63 nmol/l after the run (p lt 0.05). The pre-run salivary testosterone levels marginally correlated with the corresponding half-marathon running times (p=0.068, 95% bootstrap CI for slope -0.40 to -0.06). However, post-run salivary testosterone levels significantly correlated with the corresponding half-marathon running times (p=0.011, 95% bootstrap CI for slope -0.41 to -0.16), even considering correlations with the runners' age. Salivary cortisol levels, either pre- or post-run, did not correlate with the corresponding half-marathon running times. The results of this study suggest that post-exercise salivary testosterone levels could have the potential to predict performance in endurance running, at least in recreational athletes.

AB  - Objectives. Defining adequate reference limits (RLs) for thyroid hormones is an important task for support monitoring and the treatment of subclinical thyroid disease. We determined whether there are age-related RLs for thyroid parameters in male and female outpatients free of overt thyroid disease. Design. We analyzed 22,860 results (11,440 male and 11,420 female outpatients above the age of 18) for thyrotropin (TSH), free thyroxine (fT4) and total triiodothyronine (T3) that were stored in our laboratory information system between 2008 and 2011. We calculated the 2.5th and 97.5th centiles for the analyzed thyroid parameters. Results. Our results indicate higher TSH levels with ageing, with a significant difference (p  lt  0.05) between the 97.5th centiles for males and females older than 70 (5.07 mIU/L and 4.10 mIU/L), but also a significant difference between male and female fT4 from 31 to 40 and from 41 to 50 years old (18.4 vs 14.9 pmol/L and 19.0 vs 15.9 pmol/L, p  lt  0.05), respectively. Overall indirect estimates of the 97.5th centiles for TSH for males and females were not significantly different and were below the generally recommended upper limit (4.01 mIU/L and 4.20 mIU/L, respectively). In addition, we found no statistically signifi cant change in mean T3 values in the analyzed population. Conclusions. This cross-sectional study indicates change in TSH and fT4 levels with ageing and gender-related upper limits. This suggests that by using indirect estimation a laboratory could provide clinicians with more accurate gender- and age-specific RLs for thyroid parameters.

Our results indicate higher TSH levels with ageing, with a significant difference (p  lt  0.05) between the 97.5th centiles for males and females older than 70 (5.07 mIU/L and 4.10 mIU/L), but also a significant difference between male and female fT4 from 31 to 40 and from 41 to 50 years old (18.4 vs 14.9 pmol/L and 19.0 vs 15.9 pmol/L, p  lt  0.05), respectively. Overall indirect estimates of the 97.5th centiles for TSH for males and females were not significantly different and were below the generally recommended upper limit (4.01 mIU/L and 4.20 mIU/L, respectively). In addition, we found no statistically signifi cant change in mean T3 values in the analyzed population. Conclusions. This cross-sectional study indicates change in TSH and fT4 levels with ageing and gender-related upper limits. This suggests that by using indirect estimation a laboratory could provide clinicians with more accurate gender- and age-specific RLs for thyroid parameters.",

AB  - Background: The aim of this work was to determine indirect reference intervals from patients' results obtained during routine laboratory work. This could be an accurate alternative to the laborious and expensive job of producing reference intervals for populations according to international recommendations. Methods: All the results for thyrotropin (TSH), total and free thyroxine, and triiodothyronine (T4, fT4, T3, and fT3) stored in our laboratory information system between 2008 and 2011 were included in this study. We used logarithmic transformation of the raw data to exclude outliers. After visual observation of the data distribution, we estimated non-parametric reference intervals. A standard normal deviation test was performed to test the significance of differences between subgroups. Results: There was no significant difference in the serum levels of the analyzed thyroid parameters, so we calculated combined reference values. However, we found a significant difference in TSH values between ambulatory and hospitalized patients, but only in 2011. Indirect reference values for TSH, T4, fT4, T3 and fT3 were 0.42 - 3.67 mIU/L, 66.0 - 136.10 nmol/L, 10.20 - 18.40 pmol/L, 1.10 - 2.39 nmol/L, and 3.17 - 5.59 pmol/L, respectively. Conclusions: The indirect determination of laboratory-specific reference intervals using patients' laboratory data is a relatively easy and inexpensive method. Also, indirect reference limits will be more precise and true if skewness and kurtosis of the distribution are not too large.

AB  - Objective: Interleukin 6(IL6) has the ability to influence each level of the hypothalamo-pituitary-adrenocortical (HPA) axis. The aim of the study was to test whether IL6 concentration correlates with the adrenal cortex response to ACTH in healthy humans. We postulated that higher basal IL6 concentration would be associated with the higher cortisol response to the stimulation. Design and methods: Basal IL6 concentration was measured and a low dose (1 mu g) ACTH test was performed to assess cortisol response. apparently healthy Subjects (11 male. 16 female. mean age 31.1 years. age range 22-47 years) were included in the study. Results: Data are presented as mean +/- S.E.M. Basal IL6 level was 0.84 +/- 0.10 pg/ml, Basal cortisol was 351.9 +/- 18.3. nmol/l. Maximal cortisol during synacthen test was 653.0 +/- 20.6 nmol/l. Maximal cortisol increment was 301.1 +/- 20.0 nmol/l. IL6 concentration was not correlated with basal or maximal cortisol concentration. but correlated significantly with cortisol increment (r=0.63. 95%. confidence interval) 0.42-0.83). Conclusions: In our study. We found that higher basal IL6 concentration is associated with the higher cortisol response to ACTH stimulation. Based on previous research and our data, IL6, even in low concentrations and under physiologic conditions, modulates adrenal cortex responsivity to ACTH. Therefore. it seems that immune modulation of HPA axis is also present under physiologic and not only pathologic conditions.
