How is drug-susceptible pulmonary tuberculosis (TB) treated during the continuation phase?
Use the following practices for treatment of drug-susceptible pulmonary TB during the continuation phase (Recommendation 4): Daily dosing or treatment three times per week is recommended. If intermittent therapy is needed, treatment three times per week is preferred. Avoid generally the once weekly regimen of INH 900/RPT 600.
What drugs are used to treat tuberculosis (TB)?
There are 10 drugs currently approved by the U.S. Food and Drug Administration (FDA) for treating TB. Of the approved drugs, the first-line anti-TB agents that form the core of treatment regimens are: isoniazid (INH) rifampin (RIF) ethambutol (EMB) pyrazinamide (PZA) TB Regimens for Drug-Susceptible TB.
What is the minimum duration of treatment of drug sensitive TB?
Duration of treatment with the current first-line anti-TB drugs is a minimum of 6 months. Reducing the duration of the treatment from six to two months or less could result in significant increase of adherence to treatment and cost reduction.
How long is TB medication therapy?
You'll be prescribed at least a 6-month course of a combination of antibiotics if you're diagnosed with active pulmonary TB, where your lungs are affected and you have symptoms. The usual treatment is: 2 antibiotics (isoniazid and rifampicin) for 6 months.
Why is TB treatment so long?
A long treatment is required because antibiotics work only when the bacteria are actively dividing, and the bacteria that cause TB can rest without growing for long periods. This treatment is necessary to keep the latent TB infection from developing into active disease.
How long is TB prophylaxis?
A one-month antibiotic regimen to prevent active tuberculosis (TB) disease was at least as safe and effective as the standard nine-month therapy for people living with HIV, according to the results of a large international clinical trial.
What are the objectives of tuberculosis treatment?
The objectives of tuberculosis therapy are (1) to rapidly reduce the number of actively growing bacilli in the patient, thereby decreasing severity of the disease , preventing death and halting transmission of M. tuberculosis; (2) to eradicate populations of persisting bacilli in order to achieve durable cure (prevent relapse) after completion of therapy; and (3) to prevent acquisition of drug resistance during therapy.
What is the responsibility of a tuberculosis patient?
The responsibility for successful treatment of tuberculosis is placed primarily on the provider or program initiating therapy rather than on the patient. It is well established that appropriate treatment of tuberculosis rapidly renders the patient noninfectious, prevents drug resistance, minimizes the risk of disability or death from tuberculosis, and nearly eliminates the possibility of relapse [95]. Provider responsibility is a central concept in treating patients with tuberculosis, no matter what the source of their care.
What is the role of public health in treating tuberculosis?
Because of the public health implications of prompt diagnosis and effective treatment of tuberculosis, most low-incidence countries designate a government public health agency as legal authority for controlling tuberculosis [12, 13]. The optimal organization of tuberculosis treatment often requires the coordination of public and private sectors [14–16]. In most settings, a patient is assigned a public health case manager who assesses needs and barriers that may interfere with treatment adherence [17]. With active input from the patient and healthcare providers, the case manager, together with the patient, develops an individualized “case management plan” with interventions to address the identified needs and barriers [18–20] (see PICO Question 1 and Supplementary Appendix B, Evidence Profiles 1–3). The least restrictive public health interventions that are effective are used to achieve adherence, thereby balancing the rights of the patient and public safety. Given that tuberculosis treatment requires multiple drugs be given for several months, it is crucial that the patient be involved in a meaningful way in making decisions concerning treatment supervision and overall care. International standards have been developed that also emphasize the importance of using patient-centered approaches to the management of tuberculosis [14–16].
What is the decision to initiate combination chemotherapy for tuberculosis?
The decision to initiate combination chemotherapy for tuberculosis is based on clinical, radiographic, laboratory, patient, and public health factors (Figure 1). In addition, clinical judgment and the index of suspicion for tuberculosis are critical in making a decision to initiate treatment.
Is co-trimoxazole used for HIV?
Whereas the WHO recommends routine co-trimoxazole prophylaxis for all HIV-infected people with active tuberculosis disease regardless of the CD4 cell count [66], in high-income countries, co-trimoxazole prophylaxis is primarily used in tuberculosis patients coinfected with HIV with CD4 counts <200 cells/µL [67].
Can you manage mild adverse effects?
Mild adverse effects usually can be managed with treatment directed at controlling the symptoms ; severe effects usually require the offending drug (s) to be discontinued. If a drug is permanently discontinued, then a replacement drug, typically from a different drug class, is included in the regimen. Patients with severe tuberculosis often require the initiation of an alternate regimen during the time the offending drug (s) are held. Management of serious adverse effects often requires expert consultation. The suggested practices listed below for handling common adverse effects during treatment (ordered from most to least common) are based on expert opinion.
Is tuberculosis a low incidence disease?
It should be emphasized that these guidelines are intended for areas in which mycobacterial cultures, molecular and phenotypic drug susceptibility tests, and radiographic facilities are available on a routine basis—typically low-incidence (<100 tuberculosis cases per million population), well-resourced countries, where in some settings tuberculosis epidemiology is at or nearing preelimination levels (<10 cases per million) [96, 97]. The WHO has developed tuberculosis practice guidelines (currently under revision) specifically for high-incidence, resource-limited areas of the world [98].
What is the goal of TB treatment?
The objectives of TB therapy are: Cure the individual patient and minimize risk of death and disability; Reduce transmission of M. tuberculosis to other persons; and.
How often should I treat TB?
If it is difficult to treat daily or three times per week, the use of treatment two times per week after an initial two weeks of daily therapy may be considered for patients with: Low risk of relapse (i.e. drug-susceptible TB organisms, that at the start of treatment is non-cavitary and/or smear negative) and.
What is a TB guidelines?
The guidelines provide recommendations on the clinical and public health management of tuberculosis (TB) in children and adults in well-resourced settings. The guidelines provide evidence-based recommendations that have been developed using GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology.
What is case management in TB?
Case management is defined as patient education and counseling, field and home visits, integration and coordination of care with specialists and medical home care, patient reminders, and incentives and enablers. (Recommendation 1)

What is drug susceptibility testing?
Drug susceptibility testing is a difficult procedure to standardize, and proficiency in performing these tests requires an understanding of many elements , including the. Origin of drug resistance and the criteria for resistance. Potency and stability of drugs during laboratory manipulation.
How long does it take to complete the LB test?
The LB uses an indirect proportion method for testing M. tuberculosis complex mycobacteria to 12 drugs at 35C on Middlebrook 7H10 agar. The test requires 1 month to complete. Growth on the control medium is compared to the growth on the drug-containing medium to determine susceptibility or resistance. When performed properly, this method allows a quantitation of the proportion of mutants resistant to a drug and can detect the 1% proportion of drug- resistant mutants above which therapeutic failure is likely.
