Updating the WHO target product profile for next-generation Mycobacterium tuberculosis drug susceptibility testing at peripheral centres.

There were approximately 10 million tuberculosis (TB) cases in 2020, of which 500,000 were drug-resistant. Only one third of drug-resistant TB cases were diagnosed and enrolled on appropriate treatment, an issue partly driven by a lack of rapid, accurate drug-susceptibility testing (DST) tools deployable in peripheral settings. In 2014, World Health Organization (WHO) published target product profiles (TPPs) which detailed minimal and optimal criteria to address high-priority TB diagnostic needs, including DST.

World Health Organization recommendations on the treatment of drug-resistant tuberculosis, 2020 update.

Antimicrobial resistance is a major public health problem globally. Likewise, forms of tuberculosis (TB) resistant to first- and second-line TB medicines present a major challenge for patients, healthcare workers and healthcare services. In November 2019, the World Health Organization (WHO) convened an independent international expert panel to review new evidence on the treatment of multidrug- (MDR) and rifampicin-resistant (RR) TB, using the Grading of Recommendations Assessment, Development and Evaluation approach.

Using GRADE evidence to decision frameworks to choose from multiple interventions.

Background And Objective: Guideline development groups or other health care decision makers frequently encounter situations that require a simultaneous comparison of multiple interventions. This sometimes becomes apparent either when they identify questions of interest, before they formulate recommendations, or it may surface only when recommendations have already been formulated based on pairwise comparisons.

Methods: Using examples from the World Health Organization, the European Commission, and a professional society, we developed a flexible approach to developing recommendations when a multiple-intervention comparison (MC) is needed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) evidence to decision (EtD) frameworks.

Access to experimental medicines for TB: ethical and human rights considerations.

The revised edition of the WHO's has added a new chapter on compassionate use (CU) and expanded access (EA) to TB drugs. CU and EA programmes authorise access to drugs that have not yet received marketing approval outside of clinical trials. They are aimed at allowing researchers access to investigational drugs in the absence of complete evidence of efficacy and safety to patients with multidrug-resistant (MDR) or rifampicin-resistant TB (RR-TB) when no other treatment options are available.

Ethics and human rights considerations regarding involuntary isolation of people with TB.

Involuntary isolation of people with tuberculosis is rarely medically required, ethically permitted or justified on the ground of human rights law. The rare circumstances that do call for involuntary isolation must only occur once a number of conditions are met. These include just procedural protections and ensuring that all other options have been exhausted before resorting to involuntary isolation.
