Study summary

The French Tuberculosis Cohort is a prospective, national, multicenter, low-intervention study including subjects aged 18 years and older with tuberculosis disease for which inpatient treatment is initiated. The goal of this observational study is to follow-up and anti-tuberculosis treatment will be provided according to current French recommendations. Participants will provide sociodemographic, clinical, biological, radiological and bacteriological data at various protocol visits at 2 days, 1 and 2 weeks, 2 months, at the end of treatment, 12 and 24 months. Consenting participants will have samples collected at scheduled visits for the establishment of a biobank. This will include blood, urine, breath and hair samples. The positive mycobacterial strains will constitute a specimen bank.

Read the detailed description

Main objectif:

To describe the sociodemographic, clinical, radiologic, and bacteriologic characteristics, as well as comorbidities and their impact on treatment outcomes and relapse rate up to 24 months after the start of anti-tuberculosis treatment in people with tuberculosis disease diagnosed in France.

Secondary objectives:

  • Evaluate the effects of immunosuppression (HIV infection, organ transplantation, immunosuppressive treatments) on tuberculosis symptomatology, complications (including immune reconstitution inflammatory syndromes (IRIS), and drug interactions), treatment response and survival.
  • Describe the characteristics of severe (meningeal, pericardial, miliary, etc.) or complicated forms of tuberculosis, including resistant tuberculosis, their management (treatment of resistant TB, use of anti-TNF, corticoids), their impact on treatment outcomes, relapse rates up to 24 months, sequelae and survival.
  • Describe representations of the disease and its care, its impact on quality of life, and the effect of social determinants, situations of precariousness, health literacy, belonging to key populations (incarcerated, migrant and/or homeless people) as well as mental health disorders and addictions on compliance, experience of the disease, follow-up, and treatment outcomes.
  • Describe the effect of new short-course tuberculosis treatments on adherence, disease experience, follow-up and treatment outcomes.
  • Describe post-tuberculosis pulmonary sequelae, study their association with immunosuppression, pharmacological dosages, other comorbidities, tobacco and alcohol consumption, and measure physiological, structural and functional disorders, their impact on quality of life and survival.
  • Study the potential diagnostic and prognostic value of new biomarkers in people with tuberculosis and the effect of exposure to anti-tuberculosis treatment on response to tuberculosis therapy.

Study population

All persons included in the cohort will be followed up as part of routine care.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Aged ≥18 years.
  • Diagnosis of tuberculosis by microbiological or clinical means, including on the basis of a pathological examination for extrapulmonary tuberculosis leading to a Compulsory Declaration (CD) and treated for less than 8 days.
  • Have signed a voluntary, informed and written consent (at the latest on the day of inclusion and before any examination carried out as part of the research), or alternatively, consent from relatives in cases of tuberculous meningitis or other serious forms of tuberculosis with impaired consciousness or confusion, until the person is able to give their consent.

Exclusion criteria

Exclusion Criteria:

  • Presence of significant cognitive impairment that, in the opinion of the site investigator or designated person, may affect the ability to give reliable (except in the specific case of meningeal tuberculosis).
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Proportion of participants with successful anti-tuberculosis treatment outcome, defined as definite or probable cure, by Month 12

    Definite cure (microbiological): negative cultures (or direct examination) of respiratory specimens on two occasions during follow-up, in the last month of treatment and on an intermediate specimen, in a participant who has completed treatment and has never met the definition of treatment failure.

  19. Quality of life and mental health

    Anxiety questionnaire (GAD-7) - Score 5-9: Mild Anxiety. Score 10-14: Moderate Anxiety. Score greater than 15: Severe Anxiety. EQ-5D-5L - The UI is calculated from patient scoring of five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression). For each dimension, participants are asked to mark between 1: 'no problems' to 5: 'unable to/extreme problems'.

In men, a score of 4 or more is considered positive; in women, a score of 3 or more is considered positive. Generally, the higher the AUDIT-C score, the more likely it is that the patient's drinking is affecting his/her health and safety. Tobacco questionnaire (Fagerström) - Test for Nicotine Dependence, the three yes/no items are scored 0 (no) and 1 (yes). The three multiple-choice items are scored from 0 to 3. The items are summed to yield a total score of 0-10.

  23. Adherence to tuberculosis treatment

    Psychoactive substances questionnaire (CAGE-AID) - Item responses on the CAGE are scored 0 or 1, with a higher score an indication of alcohol problems.
