Abstract (croatian) Cilj: Otkrivanje latentne tuberkuloze sukladno nacionalnim smjernicama uključuje procjenu rizika, radiografsku pretragu, izvođenje tuberkulinskog kožnog / PPD testa (PPD – purificirani
proteinski derivat) i/ili novijeg ex vivo testa otpuštanja interferona gama (engl. Interferon Gamma Release Assay – IGRA). U radu je analizirana dinamika izvođenja i rezultati dobiveni dijagnostičkom
primjenom imunoenzimske IGRA pretrage na M. tuberculosis. Metode: Izvršena je retrospektivna analiza rezultata Quantiferon-TB Gold In-Tube (QFT-GIT) testiranja provedenih u Laboratoriju za dijagnostiku tuberkuloze Nastavnog zavoda za javno zdravstvo Primorsko-goranske
županije (Hrvatska). Rezultati: U sedmogodišnjem razdoblju (2007. – 2013.) u Laboratoriju za dijagnostiku tuberkuloze primjenom QFT-GIT testa analizirano je 2.110 uzoraka krvi pacijenata koji su pripadali različitim dobnim skupinama (od dobi od mjesec dana do 95 godina; x̄ = 41,9 godina; SD = 29,1; mod 56 godina). Rezultati analize su bili pozitivni u 585 (27,7 %), negativni u 1.498 (71 %) uzoraka, a u 27 (1,3 %) izvršenih pretraga su bili neodredivi. Pozitivni nalazi
podjednako su zastupljeni u pretragama izvršenim za muškarce (29 % od 1.058 pretraga) i žene (26 % od 1.052 pretrage). Veća zastupljenost pozitivnih nalaza zabilježena je u osoba starijih od
56 godina, napose u dobnoj skupini od 81 do 85 godina (61 % od 44 pretrage). Prema uputnoj dijagnozi pozitivni nalazi su zastupljeniji kod hiperreaktora (40,5 % od 84 analize), TB kontakata (35,1 % od 464 analize) i zdravstvenih radnika (34,9 % od 43 analize). Rasprava i zaključci: Primjena in vitro IGRA QFT-GIT testa u kombinaciji s konvencionalnim metodama danas je prepoznata kao dijagnostički postupak koji ima značajnu ulogu u otkrivanju LTB-a, što predstavlja važan korak u prevenciji tuberkuloze, posebice kod rizičnih skupina.
Abstract (english) Aim: Tuberculosis (TB) remains a major global public health problem. Screening for latent tuberculosis infection (LTB) usually involves risk assessment, chest X-ray, the tuberculin skin/PPD (Purified Protein Derivate) test, and/or interferon-gamma release assay (IGRA), according to country-specific guidelines. This paper describes the frequency of application and the results obtained by enzyme-linked immunosorbent IGRA assay for M. tuberculosis. Methods: We conducted a retrospective analysis of the results obtained using Quantiferon-TB Gold In-Tube (QFT-GIT) analysis at the Laboratory for the diagnosis of tuberculosis – Teaching Institute of Public Health County Primorsko-goranska (Croatia). Results: In the seven-year period
(2007–2013) QFT-GIT analysis were processed in 2110 blood samples of patients from different age groups (aged 1 month-95 years; x̄ = 41.9 years; SD = 29.1; mode 56 years). Results were positive in 585 (27.7 %) samples, whereas negative results were found in 1498 (71 %) cases, and in 27 (1.3 %) samples the results were indeterminate. Positive results were distributed equally among males (29 % of 1058 samples) and females (26 % of 1052 samples). Higher incidence of positive results was observed in people over the age of 56, especially in the age group between 81-85 years (61 % of 44 tests). Positive results were most common in the group of hyperreactors (40.5 % of 84 tests) then in TB contacts (35.1 % of 464 tests), as well as health workers (34.9 % of 43 tests). Discussion and Conclusions: Applying in vitro IGRA QFT-GIT test in combination with conventional methods is recognized as a diagnostic method that plays an important role in uncovering LTB and as such represents an important step in prevention of tuberculosis, especially in high-risk groups.
