AB  - Introduction. Thyroid peroxidase-specific autoantibodies (TPO Abs) are mostly measured in patients with autoimmune thyroid diseases. The aim of this study was to compare TPO Ab concentrations measured by two radioimmunoassays. Material and methods. Our investigation included 38 patients. Sera concentrations of TPO Abs were measured by using Cis biointernational (France) and Immunotech (Czech Republic) assays. Results. Concentrations obtained by two assays were extensively different. The values measured by Cis biointernational assay were higher than ones obtained by Immunotech assay. The statistical arrangement of results showed the direct correlation between the two assays, with the coefficient of agreement R=0.6239 (p lt 0.001). The analysis of relative values (ratio of measured and upper limit values given by the manufacturer) demonstrated the statistically significant difference (p=0.003) between values measured by Cis biointernational (18.94±37.22) and by Immunotech assay (4.22±8.22) concerning the distinction between normal and raised concentrations of TPO Abs. The agreement of results (enhanced or normal TPO Ab concentrations in both tests) was shown in 30 sera samples (78.95%), but in residual 8 sera (21.05%) normal TPO Ab concentrations were obtained by Immunotech, and enchanced by Cis biointernational assay. There is no difference in capability of distinction between normal and pathological results between the two tests (χ2=3.484, p gt 0.05). The highest concentration of TPO Ab measured by Cis biointernational assay was not the highest one in Immunotech assay, which might be a reflection of different specificity of antibodies used in two diagnostic tests. Conclusion. TPO Ab concentrations obtained by Cis biointernational and Immunotech assays are very different. In several sera samples, normal concentrations of TPO autoantibodies were obtained by Immunotech assay and enhanced by Cis biointernational assay. The highest value obtained by one is not the highest value measured by another assay we used.
AB  - Autontitela specifična za tiroidnu peroksidazu autoantitela specifičnih za tiroidnu peroksidazu prevashodno se određuju radi dijagnoze autoimunih bolesti štitaste žlezde. Cilj rada bio je da se uporede koncentracije autoantitela specifičnih za tiroidnu peroksidazu dobijene korišćenjem dva testa: Cis bionternational (Francuska) i Immunotech (Češka Republika). Ispitivanjem je obuhvaćeno 38 ispitanika. Iako su se koncentracije autoantitela specifičnih za tiroidnu peroksidazu u ispitivanim serumima znatno razlikovale i u apsolutnim i u relativnim vrednostima, statističkom obradom rezultata pokazana je direktna korelacija rezultata merenja ova dva testa, sa koeficijentom R=0,6239 (p lt 0,001). Na osnovu analize relativnih vrednosti. pokazana je statistički značajna razlika (p=0,003) između srednjih vrednosti rezultata izmerenih testovima Cis (18,94±37,22) i Immunotech (4,22±8,22). Slaganje rezultata pokazano je u 78,95% seruma, dok je u 21,05% seruma testom Immunotech dobijena normalna, a testom Cis biointernational granična ili povećana koncentracija antitela. Statistički podaci su pokazali da se testovi ne razlikuju po razdvajanju patoloških od normalnih vrednosti (χ2=3,484, p gt 0,05). Iako koncentracije autoantitela specifičnih za tiroidnu peroksidazu izmerene pomoću testova Cis biointernational i testom Immunotech pokazuju značajan stepen korelacije, njihove i apsolutne i relativne vrednosti znatno se razlikuju.

AB  - It is generally accepted that autoimmune thyroid disorders, Graves disease and Hashimoto thyroiditis, differ in pathogenesis and clinical implications. In Graves disease the basic pathogenetic mechanism is B lymphocyte activation which produce auto antibodies specific for TSH receptor (TSHR) which binding to thyrocyte membrane causes their long-termed stimulation which gives as a result the occurrence of hyperthyrosis. On the other hand in Hashimoto thyroiditis lymphocyte accumulation occurs and they cause gradual thyrocyte damage and hypothyrosis development. However, it was found that the reisa certain genetic predisposition for both autoimmune thyroid diseases and that they can appear among several members of the same family. Besides in the serum of the patients with Graves disease and Hashimoto thyroiditis the presence of autoantibodi esspecific for dominant thyroid autoantigenes: TSHR, thyroperoxidase (TPO) and thyroglobulin (Tg) can be found as indicators of the auto immune process in thyroid gland. For these reasons both autoimmune diseases of thyroid gland sometimes are marked with the common name: autoimmune thyroid disease. As cell and molecule mechanisms included in initiation of the autoimmune process in thyroid gland that define the type and natural course of disease have not completely been explained, in this review the data from the literature considering pathogenesis of autoimmune diseases of thyroid gland have been shown. After introductory considerations, dominant autoantigenes and autoantibodies (as indicators of autoimmune process in thyroid gland) are shown in details, as well as mechanisms included in effector phase of autoimmune process which cau se the thyroid cell damage. The role of disturbance in regulation of the apoptosis process is especially analyzed as they could effect the development of autoimmune diseases of thyroid gland.
AB  - Prihvaćeno je shvatanje da se autoimunske bolesti štitaste žlezde Graves-ova bolest i Hashimoto tireoiditis razlikuju po patogenezi i kliničkim posledicama. U Graves-ovoj bolesti je osnovni patogenetski mehanizam aktivacija Blimfocita koji produkuju auto antitela specifična za TSH receptor (TSHR), čije vezivanje za membranu tireocita uzrokuje njihovu dugotrajnu stimulaciju, sa posledičnim nastankom hipertireoze. S druge strane, u Hashimoto tireoiditi su nastaje akumulacija limfocita koji prouzrokuju postepeno oštećenje tireocita i nastanak hipotireoze. Međutim utvrđeno je da za obe autoimunske tireoidne bolesti postoji određena genetska predispozicija i da se one mogu javiti kod više članova u istoj porodici. Osim toga, u serumu obolelih od Graves-ove bolesti i Hashimoto tireoiditi sa se može pokazati prisustvo autoantitela specifičnih za dominantne tireoidne autoantigene (receptor za TSH, tireoperoksidazu i tireoglobulin) koji predstavljaju pokazatelje autoimunskog procesa u štitastoj žlezdi. Iz tih razloga se obe autoimunske bolesti štitaste žlezde nekad označavaju zajedničkim nazivom: autoimunska bolest štitaste žlezde. Budući da ćelijski i molekulski mehanizmi koji su uključeni u inicijaciju autoimunskog procesa u štita stoj žlezdi, i opredeljuju vrstu i prirodni tok bolesti, nisu potpuno rasvetljeni, u ovom radu su prikazani podaci iz literature koji se odnose na patogenezu autoimunskih bolesti štitaste žlezde. Nakon uvodnih razmatranja, detaljno su prikazani dominantni autoantigeni i autoantitela (kao pokazatelji autoimunskog procesa u štitastoj žlezdi), kao i mehanizmi uključeni u efektorsku fazu autoimunskog procesa koji uzrokuju oštećenje tireocita. Posebno je analizirana uloga poremećaja u regulaciji procesa apoptoze u nastanku autoimunskih bolesti štitaste žlezde.
