A neopterin szintézisét a T-lymphocyták által termelt interferon-γ indukálja. Emelkedett szérumszintje a celluláris immunrendszer aktiválódását jelzi. Cél: Vizsgálatunkban arra a kérdésre kerestünk választ, hogy autoimmun pajzsmirigybetegekben a neopterinszintek összefüggnek-e a betegség klinikai stádiumával, előre jelezheti-e a neopterin a kórkép recidíváját, tehát alkalmas-e immunológiai monitorizálásra. Módszerek: 137, Basedow-kórban (47 hyperthyreosis, 36 euthyreosis, 7 hypothyreosis, 34 gyógyult, 13 relapsus), 25 Hashimoto-thyreoiditisben, 14 toxikus adenomában szenvedő nőbetegben határozták meg a szérum neopterin, pajzsmirigy-stimuláló hormon, szabad tiroxin, szabad trijód-tironin, tireoglobulin- és pajzsmirigyperoxidáz elleni antitestek szintjét. Eredmények: A neopterinszint szignifikánsan magasabb volt a Basedow-kóros betegekben (hyperthyreosis, euthyreosis, hypothyreosis és recidív hyperthyreosis esetén is), valamint Hashimoto-thyreoiditises betegeinkben. Pozitív korrelációt találtak a neopterin és tireoglobulin elleni, valamint pajzsmirigyperoxidáz elleni antitestek szintje között, de nem találtak összefüggést a neopterinszint és a pajzsmirigyhormonok, pajzsmirigy-stimuláló hormon, illetve pajzsmirigy-stimuláló hormon-receptor elleni antitestek értékei között. Következtetések: A magasabb szérumneopterin-szint a háttérben zajló autoimmun folyamatot tükrözi, nem mutat összefüggést a pajzsmirigyhormonok változásával. A neopterin meghatározása fontos jelzője lehet az autoimmun betegségek fellángolásának. Orv. Hetil., 2012, 153, 1127–1131.
