Thirty patients were evaluated with QTF-G for detection of LTBI before and after 6 months of TNF-\u03b1 antagonist treatment. QTF-G was also performed on 49 healthy controls. QTF-G results were recorded as positive, negative, or indeterminate. A positive TST was defined as \u2265 5 mm for RA and AS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results.<\/jats:title><jats:p>The percentages of positive QTF-G were comparable in RA and AS (37% vs 32%). The rate of positive QTF-G in healthy controls (29%) was also similar to RA and AS. In contrast to QTF-G results, a high rate of TST positivity was observed in AS compared to RA (82% vs 55%; p = 0.02). The total agreement between QTF-G and TST was observed to be 61% (\u03ba = 0.29) in the whole group, 70% (\u03ba = 0.42) in RA, and 49% (\u03ba = 0.14) in AS. After 6 months of treatment with TNF-\u03b1 antagonists, a high rate of QTF-G change was observed in patients with indeterminate results (23% vs 3%; p = 0.03).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion.<\/jats:title><jats:p>The comparable prevalence of LTBI among the study groups according to QTF-G supports the view that QTF-G is less susceptible to external factors than TST. Sequential testing for QTF-G in patients with indeterminate or negative results may also be helpful in discriminating LTBI better.<\/jats:p><\/jats:sec>","DOI":"10.3899\/jrheum.090268","type":"journal-article","created":{"date-parts":[[2009,11,17]],"date-time":"2009-11-17T03:20:20Z","timestamp":1258428020000},"page":"2675-2681","source":"Crossref","is-referenced-by-count":34,"title":["Agreement Between Quantiferon-TB Gold Test and Tuberculin Skin Test in the Identification of Latent Tuberculosis Infection in Patients with Rheumatoid Arthritis and Ankylosing Spondylitis"],"prefix":"10.3899","volume":"36","author":[{"given":"NEVSUN","family":"INANC","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SIBEL ZEHRA","family":"AYDIN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SAIT","family":"KARAKURT","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PAMIR","family":"ATAGUNDUZ","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SULE","family":"YAVUZ","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HANER","family":"DIRESKENELI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2262","published-online":{"date-parts":[[2009,11,16]]},"reference":[{"key":"2018112909213657000_36.12.2675.1","doi-asserted-by":"publisher","DOI":"10.1016\/S0891-5520(05)70149-5"},{"key":"2018112909213657000_36.12.2675.2","first-page":"1436","article-title":"Increased risk of tuberculosis in patients with rheumatoid arthritis","volume":"30","author":"Carmona","year":"2003","journal-title":"J Rheumatol"},{"key":"2018112909213657000_36.12.2675.3","doi-asserted-by":"publisher","DOI":"10.1002\/art.11137"},{"key":"2018112909213657000_36.12.2675.4","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa011110"},{"key":"2018112909213657000_36.12.2675.5","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2006.061937"},{"key":"2018112909213657000_36.12.2675.6","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMsa031667"},{"key":"2018112909213657000_36.12.2675.7","doi-asserted-by":"publisher","DOI":"10.1002\/art.21043"},{"key":"2018112909213657000_36.12.2675.8","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/kei103"},{"key":"2018112909213657000_36.12.2675.9","doi-asserted-by":"publisher","DOI":"10.1136\/ard.62.8.791"},{"key":"2018112909213657000_36.12.2675.10","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2004.029041"},{"key":"2018112909213657000_36.12.2675.11","doi-asserted-by":"publisher","DOI":"10.1093\/clinids\/17.6.968"},{"key":"2018112909213657000_36.12.2675.12","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(04)01206-X"},{"key":"2018112909213657000_36.12.2675.13","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2002.004598"},{"key":"2018112909213657000_36.12.2675.14","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/kem351"},{"key":"2018112909213657000_36.12.2675.15","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2007.069799"},{"key":"2018112909213657000_36.12.2675.16","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2007.070789"},{"key":"2018112909213657000_36.12.2675.17","first-page":"770","article-title":"Comparison of an in vitro tuberculosis interferon-gamma assay with delayed-type hypersensitivity testing for detection of latent Mycobacterium tuberculosis: a pilot study in rheumatoid arthritis","volume":"35","author":"Greenberg","year":"2008","journal-title":"J Rheumatol"},{"key":"2018112909213657000_36.12.2675.18","doi-asserted-by":"crossref","first-page":"315","DOI":"10.1002\/art.1780310302","article-title":"The American Rheumatism Association 1987 revised criteria for the classification of rheumatoid arthritis","volume":"31","author":"Arnett","year":"1988","journal-title":"Arthritis Rheum"},{"key":"2018112909213657000_36.12.2675.19","doi-asserted-by":"crossref","first-page":"361","DOI":"10.1002\/art.1780270401","article-title":"Evaluation of diagnostic criteria for ankylosing spondylitis.
