Study summary

Clinical test (essay) randomized to evaluate the toxicity adherence and efficiency of the chemoprophylaxis of tuberculosis (TB) in subjects with Diabetes Mellitus (DM) and latent TB. (600 subjects followed(continued) by 15 months). 3rd stage. Patients with DM and TB will be included to determine if the strict control of the dm achieved in clinics of the first level of attention improves clinical manifestations of tb, the result of treatment, the frequency of relapses, the mortality and the transmission to contacts.

Elispot will be used to measure TB development and the time for the bacteriological negativization and biochemical parameters as well as tuberculin skin test (TST), quantiferon, in contacts. (160 patients 600 contacts followed(continued) for 12 months). additional there will be evaluated the socioeconomic impact of both diseases and his(her) control. 1er year: transverse study and recruitment years 2 and 3 participants' follow-ups in clinical tests(essays).

    Patients with a -TST

    In all patients with a negative TST test, Isoniazid 300 mg per day will be administered for 6 months

    Drug: Isoniazid 300Mg Tab

  • Active comparator
    Patients with a +TST

    In patients with a +TST test researchers will test for HIV, hepatic function and we will take a chest x-ray. Isoniazid 300 mg per day will be administered for 6 months

    Drug: Isoniazid 300 MG

  • Active comparator

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 17, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
