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)
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.

Title : Recommendations for use of an isoniazid-rifapentine regimen with direct observation to treat latent Mycobacterium tuberculosis infection Personal Author(s) : Jereb, John A.;Goldberg, Stefan V.;Powell, Krista. (cdc.gov)
The antimycobacterial rifapentine ( Priftin ), which was previously approved for use against active pulmonary TB caused by Mycobacterium tuberculosis , has now been approved by the US Food and Drug Administration (FDA) for use, in combination with isoniazid, in the treatment of latent TB infection. (medscape.com)
FDA approval for the new indication was partially based on a randomized study of more than 6000 patients in which a 12-dose, once-weekly regimen of directly observed therapy (DOT) with rifapentine plus isoniazid was compared with a regimen consisting of 9 months of self-administered daily isoniazid. (medscape.com)
The cumulative rate of tuberculosis disease development was 0.16% in the rifapentine-isoniazid group (5 out of 3074 patients), compared with 0.32% in the isoniazid group (10 out of 3074 patients). (medscape.com)

11 While the regimen includes Rifampicin and Ethambutol, two of the standard first-line anti-TB drugs, the length of the TB regimen is not sufficient to address M. avium complex infections. (who.int)

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. (aidsmap.com)
Another large retrospective study carried out in Kenya found no difference in the risk of premature birth or other adverse birth outcomes between women who started isoniazid preventive therapy (IPT) during pregnancy and those who didn't. (aidsmap.com)
The two studies provide reassuring evidence that isoniazid preventive treatment does not result in a higher rate of adverse birth outcomes in pregnant women. (aidsmap.com)

We'll be discussing the use of preventive therapy for at-home exposure to drug-resistant TB. (cdc.gov)
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)
However, since use of such a regimen rarely results in true primary prevention (i.e., prevention of infection in individuals exposed to infectious tuberculosis), the ATS and CDC currently state that "treatment of latent tuberculosis infection" rather than "preventive therapy" more accurately describes the intended intervention and potentially will result in greater understanding and more widespread implementation of this tuberculosis control strategy. (antiinfectivemeds.com)
TB incidence varies over time following ART initiation, and is particularly high during the first 3 months post-ART, reinforcing the importance of TB screening prior to starting ART and use of isoniazid preventive therapy once active TB is excluded. (biomedcentral.com)

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)
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)

Isoniazid usually is used alone for the treatment of latent tuberculosis infection to prevent the development of clinical tuberculosis. (antiinfectivemeds.com)
The ATS and CDC state that since the general population of the US has an estimated M. tuberculosis infection rate of 5-10% and the annual incidence of new tuberculosis infection without known exposure is estimated to be 0.01-0.1%, the tuberculin skin test has a low positive predictive value in individuals without a known or likely exposure to M. tuberculosis. (antiinfectivemeds.com)
