In settings where TB transmission risks are low, it may be fine to focus primarily on preventing latent TB infection from becoming active TB disease - with short-course curative TB regimens - but in settings where the risk of being reinfected with TB is high, more drastic measures to prevent reinfection with TB may also be needed. (aidsmap.com)

Among the M. tuberculosis isolates recovered from the sputum of these 64 patients, 46 (71.9%) isolates were simultaneously resistant to rifampicin and isoniazid (MDR), and 30 (46.9%) isolates were resistant to pyrazinamide, Resistance to amikacin was detected in 17 (26,5%) isolates whereas resistance to moxifloxacin and linezolid was detected in 1 (1.5%) and 2 (3.1%) isolates respectively.

Adding to CDC's current recommendations for administering isoniazid preventive therapy to HIV-infected persons with positive tuberculin skin tests and to HIV-infected persons who were exposed to patients with infectious TB, this report also describes in detail the use of new short-course (i.e., 2 months) multidrug regimens (e.g., a rifamycin, such as rifampin or rifabutin, combined with pyrazinamide) to prevent TB in persons with HIV infection. (cdc.gov)
Not just antiretroviral therapy (ART), not just ART plus IPT [isoniazid preventive therapy], but other things as well, and if we do all of these things - and all of these things are achievable now - we could really start to make a big difference in terms of TB prevention. (aidsmap.com)
As previously reported by aidsmap , the Thibela TB study showed that giving a nine-month course of isoniazid preventive therapy (IPT) to everyone working at randomly selected South African gold mines had no effect on TB incidence, TB prevalence or all-cause mortality in the population, when compared to a cluster of gold mines randomised to standard TB programme management.

Previously, "preventive therapy" or "chemoprophylaxis" was used to describe a simple drug regimen (e.g., isoniazid monotherapy) used to prevent the development of active tuberculosis disease in individuals known or likely to be infected with M. tuberculosis. (antiinfectivemeds.com)
Although high-risk group screening for latent TB infection is performed by the majority of countries, only 6 (19.4%) provided figures on preventive treatment completion rates. (ersjournals.com)
Furthermore, with the commitments from governments and donors, the availability of shorter regimens is expected to facilitate uptake of tuberculosis preventive treatment. (essentialmeds.org)
The Expert Committee therefore recommended adding the fixed-dose combination of isoniazid and rifapentine to the core list of the EML and EMLc for tuberculosis preventive treatment for use in line with dosing recommendations in WHO guidelines. (essentialmeds.org)

While rifapentine-containing regimens for the treatment of both TB disease and latent TB infection are effective, there are frequent drug exposure-dependent side effects. (cdc.gov)

Regimens of INH monotherapy have been shown to prevent TB in diverse categories of patients, and use of these regimens has been extended based on expert opinion ( 2 ). (cdc.gov)
The most noteworthy change to the newest latent TB treatment guideline is preferential use of three rifamycin-based regimens of 3-4 month duration over isoniazid monotherapy for 6-9 months. (thoracic.org)

The best 2 of these drugs are rifampin and isoniazid. (cdc.gov)

TB disease (defined as clinically active disease, often with positive smears and cultures) can develop soon after exposure to M. tuberculosis organisms (primary disease) or after reactivation of latent infection. (hiv.gov)
In transplant recipients, MT infection can be due to primary infection, reactivation of latent TB foci favored by immunosuppression (IS), or, in a lesser extent (4%), it can be transmitted by the allograft [ 3 , 5 , 6 ]. (hindawi.com)
One of the keys to decreasing the incidence of active tuberculosis (TB) is preventing reactivation by aggressively treating latent TB infection. (utmb.edu)

The participating household members will be assigned at random to receive either oral delamanid daily for 26 weeks or oral isoniazid plus vitamin B6 daily for 26 weeks. (mlo-online.com)

Traditionally, it has been isoniazid given for six to nine months, but more recently, there has been a push toward shorter regimens, primarily because they are as safe and effective as isoniazid, actually potentially a little safer, but because they are shorter, the treatment completion rates are higher, and that's a good thing. (vumc.org)
Shorter regimens and interventions targeting residents of congregate settings, injection drug users, and employees of health-care facilities are needed to increase completion. (houstonmethodist.org)
Individuals on shorter regimens were shown to be 1.5-3 times more likely to complete treatment, which is beneficial as it is important to maximize its effectiveness in preventing active tuberculosis. (essentialmeds.org)

The three treatment regimens use isoniazid (INH ) Tuberculosis is an infectious disease that's been around for thousands of years, and although it's still common and fatal in parts of the world, TB is treatable and Nov 11, 2020 The discovery of antibiotics in the mid-twentieth century marked a major transition in tuberculosis (TB) treatment and control.

The use of rifabutin-containing antituberculosis regimens should always include an assessment of the patient's response to treatment to decide the appropriate duration of therapy (i.e., 6 months or 9 months). (cdc.gov)
Isoniazid is used in conjunction with other antituberculosis agents in the treatment of clinical tuberculosis. (antiinfectivemeds.com)
The Committee noted that both rifapentine and isoniazid as single agents have been included as antituberculosis medicines on the core list of the EML for several years and that the effectiveness and potential harms of the two medicines are expected to be similar for the single-pill formulations and the fixed-dose combination. (essentialmeds.org)

However, self-supervised daily INH regimens have completion rates of 60% or less in typical settings, attributable largely to the duration of ≥6 months. (cdc.gov)
As such, there is a need to determine if similarly good outcomes can be achieved in children with less-severe forms of TB using further simplified regimens and to optimize regimen composition, duration, and dosing for the more severe manifestations of TB disease also observed in children. (treatmentactiongroup.org)
These regimens have a minimum duration of 6 months (26 weeks), and consist of an initial intensive phase (2 months) and a continuation phase (usually either 4 or 7 months). (antiinfectivemeds.com)

Regimens for TB have been developed for patients, depending on their HIV status, the prevalence of multidrug-resistant disease in the community, drug allergies, and drug interactions. (unboundmedicine.com)

Three randomized controlled trials have shown that a new combination regimen of isoniazid (INH) and rifapentine (RPT) administered weekly for 12 weeks as directly observed therapy (DOT) is as effective for preventing TB as other regimens and is more likely to be completed than the U.S. standard regimen of 9 months of INH daily without DOT ( 2 5 ). (cdc.gov)
In the shorter regimen group, 21.0% of patients had unfavorable outcomes, compared with 17.2% of patients in the standard regimen group. (medscape.com)
For MDR-TB, no standard regimen can be proposed. (centerhears.com)

A total of 2,516 participants at 34 clinical sites in 13 countries participated in the trial, which demonstrated that a four-month daily treatment regimen with high-dose rifapentine and moxifloxacin is as effective as (noninferior to) the standard daily six-month regimen in curing drug-susceptible TB disease. (cdc.gov)
The second study involved a 4-month treatment regimen in which moxifloxacin was substituted for isoniazid for 2 months, followed by moxifloxacin and rifapentine twice weekly for 2 months. (medscape.com)
