The project is expected to enroll up to 50 pediatric patients over a 4-year study. Children with access to Ambulatory structures or hospitalized at University Infectious Diseases Clinic or Pediatric Clinic, University Hospital of Siena, or with access to Ambulatory or hospitalized at Pediatric Clinic USL 9 Grosseto will be enrolled. Once obtained the informed consent of patients\' parents or legal guardians, patients will be enrolled. The doctor will administer a clinical-anamnestic questionnaire, relative to the country of birth and residence, date of arrival in Italy and any stays in the country of origin (in case of foreign patient), travels abroad, risk factors for infectious diseases, type of contact with any index case, previous vaccination with BCG, date and outcome of the TST, clinical symptoms and signs suggestive of active TB, report of any instrumental investigation. Together with the collection of blood samples for routine purposes, an additional blood sample will be taken so to run IGRA test. Also patients for whom their medical doctor will independently order to run QTF-GIT test as necessary tool for the clinical diagnosis of TB will be included in the study.\n\nA retrospective analysis will be performed on patient pertaining to participant Clinics, from 1 January 2012 to 31 May 2015. Such analysis will be performed on those patients for which their medical doctor requested both intradermal Mantoux and IGRA test.\n\nExpected results:\n\n* estimation of concordance between QuantiFERON-TB Gold In Tube and TST in pediatric patients exposed to TB, with or without latent TB infection\n* Evaluation of the sensitivity of the test QTF-GIT in patients with active tuberculosis disease\n* Evaluation of specificity of testQTF-GIT in not infected patients\n* Evaluation on the possible use of QTF-GIT, together with TST, to improve the diagnosis of tuberculosis latent or active infection in pediatric subjects.\n* Evaluation of the possible diagnostic use of QTF-GIT in the child \\<5 years.', 'detailedDescription': 'The diagnosis of tuberculosis in children is a complex procedure. The commonly used test is the tuberculin skin test (TST), which shows significant limitations such as cross-reactivity with the bacillus Calmette-Guerin (BCG) used for vaccination, and other environmental mycobacteria, the possible influence of age and the immunological status of the patient, the need to return to the hospital for the re-reading of the intradermal reaction. Since 2001, the Food and Drug Administration approved the first of a series of new tests, called Interferon-Gamma Release Assays (IGRAs), based on the release of interferon gamma by sensitized lymphocytes in the blood of the patient. Among them, the QuantiFERON-TBGold In Tube (QTF-GIT, Cellestis Limited, Carnegie, Victoria, Australia), is a highly specific test that measures, through an ELISA assay, the release of interferon-gamma production by lymphocytes in response to an antigenic challenge to Mycobacterium tuberculosis antigens. The antigens used in the test QTF-GIT (ESAT-6, CFP-10 and the sequence of TB7.7) are in fact absent from the vaccine strain BCG and in most nontuberculous mycobacteria, giving to the QTF-GIT test greater specificity than TST. Moreover, being an in vitro test, it does not require a return visit to the reading of the result (this is particularly important in screening of contacts), which is instead carried out in an instrument (and therefore objective) and, finally, thanks to the presence of an internal positive control, it is possible to evaluate the performance of tests and reduce possible technical errors. The QTF-GIT test gave significant results in adults in terms of sensitivity and specificity, as demonstrated by a large scientific literature, and is currently used in many hospitals, in combination with the TST, for the diagnosis of tuberculosis. Since September 2012, also the Siena University Hospital introduced the QTF-GIT assay as a diagnostic test for tuberculosis diagnosis in healthcare workers and in inpatient or outpatient tested positive TST requiring detailed diagnostic investigation (eg. Previous BCG vaccination, suspected atypical mycobacteriosis, eruptive events or other skin changes that contraindicate performing intradermal reaction).\n\nDespite the important results obtained with the test QTF-GIT in adults, studies of specificity and sensitivity of the tests conducted in the pediatric age group are still limited. Some studies have shown a high specificity, while the sensitivity appears lower than the TST. The data are discordant, however, between the different studies, complicated by the fact that there is no real-Gold standard for the diagnosis of latent TB, and hence, further analysis is still needed.\n\nWhile in adults the risk of progression from latent infection to active pulmonary disease is about 5-10%, in infants (\\<1 year old) this value increases up to about 30-40%, therefore the diagnosis and the treatment of latent infections is more than ever necessary to reduce the risk of developing the disease. Thus an urgent need to identify specific and sensitive diagnostic tools that would enable better diagnosis of TB in childhood, particularly in the age group under 5 years, as clearly expressed also by the European Centre for Disease Prevention and Control (ECDC) in guidelines "Use of Interferon-gamma release assays in support of TB diagnosis" and by the resolution of the Regional Council of Tuscany Region n. 677 of 8.4.2014.\n\nThe aim of this project is to analyze the potential contribution of IGRA test, QuantiFERON-TB Gold In Tube test (QTF-GIT, Cellestis Limited, Carnegie, Victoria, Australia) in the diagnosis of tuberculosis (TB - active or latent) in pediatric subjects aged between 0 and 17 years recently exposed to infection (indicated as "contacts") or with clinical suspicion of active TB, and to compare the results obtained with those of the TuberculinSkin Test (TST), which is the gold standard. The research project is expected to enroll up to 50 pediatric patients (0- 17 years) over a 4-year study. Children with access to Ambulatory structures or hospitalized at University Infectious Diseases Clinic or Pediatric Clinic, University Hospital of Siena, or with access to Ambulatory or hospitalized at Pediatric Clinic USL 9 Grosseto will be enrolled. Once obtained the informed consent of patients\' parents or legal guardians, patients will be enrolled. The doctor will administer a clinical-anamnestic questionnaire (CRF), relative to the country of birth and residence, date of arrival in Italy and any stays in the country of origin (in case of foreign patient), travels abroad, risk factors for infectious diseases, type of contact with any index case, previous vaccination with BCG, date and outcome of the TST, clinical symptoms and signs suggestive of active TB, report of any instrumental investigation. Together with the collection of blood samples for routine purposes, an additional blood sample will be taken so to run experimental IGRA test. Also patients for whom their medical doctor will independently order to run QTF-GIT test as necessary tool for the clinical diagnosis of TB will be included in the study.\n\nA retrospective analysis will be performed on patient pertaining to participant Clinics, from 1 January 2012 to 31 May 2015.
