Patients With Tuberculosis, Mycobacteriosis or Latent Tuberculosis

Condition(s) studied

Study summary

In the last 30 years, tuberculosis (TB) has re-emerged in industrialised countries as a public health, with a decrease in incidence among the resident population and an increase in the burden of immigrants. Therefore, it becomes a priority to implement an effective TB control that relies on both rapid and reliable identification of active infections, with a adequate treatment and surveillance of resistance, but also on the identification of latent tuberculosis infections (ITBL) in populations at higher risk of progression to the active disease, representing a source of infection for the community.

Eligibility

Primary outcome measure(s)

• Analysis of epidemiological, demographic and clinical aspects of patients with tuberculosis, mycobacteriosis non-tubercular or latent tubercular infection — from 2021 to 2026
  Patients' data with biological samples for mycobacteria research and/or blood samples for immunological investigations for latent tubercular infection and clinical/radiological suspicion of mycobacteriosis or tuberculosis had been colleted from January 2012 to May 2021 (retrospective phase of the study) and from June 2021 to December 2026 (prospective phase of the study). The criteria for diagnosis of TB confirmed microbiologically are: Clinical+Imaging suggestive of tuberculosis disease;microbiological isolation of MTB and/ or molecular test for MTB (Xpert) positive;decision of the clinician to start anti-tuberculosis treatment. The criteria for diagnosing non-tubercular mycobacteriosis are: Clinical+Imaging suggestive of mycobacteriosis;isolation of NTM from at least two sputum samples or one bronchocolagement sample. The criteria for diagnosing ITBL are: positive IGRA and/or positive TST test;absence of clinical/radiological signs of tubercular disease.
