Multiparametric blood transcriptomic signatures of TB have been described as potential diagnostic tests. We sought to identify the best transcript candidates as host biomarkers for active TB, extend the evaluation of their specificity by comparison with other infectious diseases, and to test their performance in both pulmonary and extrapulmonary TB.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>METHODS.<\/jats:bold>\n                    Support vector machine learning, combined with feature selection, was applied to new and previously published blood transcriptional profiles in order to identify the minimal TB\u2011specific transcriptional signature shared by multiple patient cohorts including pulmonary and extrapulmonary TB, and individuals with and without HIV-1 coinfection.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>RESULTS.<\/jats:bold>\n                    We identified and validated elevated blood basic leucine zipper transcription factor 2 (\n                    <jats:italic>BATF2<\/jats:italic>\n                    ) transcript levels as a single sensitive biomarker that discriminated active pulmonary and extrapulmonary TB from healthy individuals, with receiver operating characteristic (ROC) area under the curve (AUC) scores of 0.93 to 0.99 in multiple cohorts of HIV-1\u2013negative individuals, and 0.85 in HIV-1\u2013infected individuals. In addition, we identified and validated a potentially novel 4-gene signature comprising CD177, haptoglobin, immunoglobin J chain, and galectin 10 that discriminated active pulmonary and extrapulmonary TB from other febrile infections, giving ROC AUCs of 0.94 to 1.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>CONCLUSIONS.<\/jats:bold>\n                    Elevated blood\n                    <jats:italic>BATF2<\/jats:italic>\n                    transcript levels provide a sensitive biomarker that discriminates active TB from healthy individuals, and a potentially novel 4-gene transcriptional signature differentiates between active TB and other infectious diseases in individuals presenting with fever.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>FUNDING.<\/jats:bold>\n                    MRC, Wellcome Trust, Rosetrees Trust, British Lung Foundation, NIHR.\n                  <\/jats:p>","DOI":"10.1172\/jci.insight.87238","type":"journal-article","created":{"date-parts":[[2016,10,5]],"date-time":"2016-10-05T11:06:06Z","timestamp":1475665566000},"source":"Crossref","is-referenced-by-count":94,"title":["Blood transcriptomic diagnosis of pulmonary and extrapulmonary tuberculosis"],"prefix":"10.1172","volume":"1","author":[{"given":"Jennifer K","family":"Roe","sequence":"first","affiliation":[{"name":"Division of Infection and Immunity, University College London, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niclas","family":"Thomas","sequence":"additional","affiliation":[{"name":"Division of Infection and Immunity, University College London, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eliza","family":"Gil","sequence":"additional","affiliation":[{"name":"Division of Infection and Immunity, University College London, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katharine","family":"Best","sequence":"additional","affiliation":[{"name":"Division of Infection and Immunity, University College London, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evdokia","family":"Tsaliki","sequence":"additional","affiliation":[{"name":"Division of Infection and Immunity, University College London, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Morris\u2011Jones","sequence":"additional","affiliation":[{"name":"Department of Microbiology, University College London Hospitals NHS Trust, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sian","family":"Stafford","sequence":"additional","affiliation":[{"name":"Division of Infection and Immunity, University College London, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nandi","family":"Simpson","sequence":"additional","affiliation":[{"name":"Division of Infection and Immunity, University College London, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karolina D","family":"Witt","sequence":"additional","affiliation":[{"name":"Blizard Institute, Queen Mary University of London, Barts and The London School of Medicine and Dentistry, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin","family":"Chain","sequence":"additional","affiliation":[{"name":"Division of Infection and Immunity, University College London, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert F","family":"Miller","sequence":"additional","affiliation":[{"name":"Research Department of Infection and Population Health, University College London, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian","family":"Martineau","sequence":"additional","affiliation":[{"name":"Blizard Institute, Queen Mary University of London, Barts and The London School of Medicine and Dentistry, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4774-0853","authenticated-orcid":true,"given":"Mahdad","family":"Noursadeghi","sequence":"additional","affiliation":[{"name":"Division of Infection and Immunity, University College London, London, United Kingdom."},{"name":"National Institute for Health Research University College London Hospitals Biomedical Research Centre, London, United Kingdom."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"232","published-online":{"date-parts":[[2016,10,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0032-1333468"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1586\/14787210.2014.899900"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00007814"},{"key":"B4","unstructured":"Global tuberculosis report 2015.
