The Paediatric Antituberculosis Drug Optimization (PADO-TB) meetings provide a forum for clinicians, researchers, financial and technical partners and other relevant key stakeholders to work together, to ensure that priority optimal paediatric formulations of TB medicines are investigated, developed and made available to children in a timely manner. After the first meeting (PADO-TB1) in February 2019, WHO hosted an interim review of the PADO-TB1 priorities. The review considered the latest WHO recommendations and other relevant developments since February 2019, such as results of clinical trials, results of pharmacokinetics and pharmacodynamics studies, new formulations available and advancements of key drugs in the TB research and development pipeline. The 4.5-hour virtual review was attended by more than 50 experts including clinicians, researchers, representatives of national TB programmes (NTPs) from high TB burden countries, community representatives, financial and technical partners, members of the Child and Adolescent TB Working Group and representatives from various international agencies, including WHO. This report summarizes the main developments presented for various TB medicines and the decisions taken with regard to the PADO-TB priority list.

Paediatric drug optimization (PADO) exercises have been convened by the World Health Organization (WHO) for various diseases, demonstrating their potential and impact to accelerate access to optimal formulations in the context of fragmented small markets for medicines for children. The WHO Global Tuberculosis Programme has convened PADO-TB meetings since February 2019 (PADO-TB1), followed by an interim review of the PADO-TB1 priorities in September 2020. Optimization of paediatric TB medicines forms part of the key actions in the Roadmap towards ending TB in children and adolescents, third edition and contributes to the achievement of the targets for ending TB in children and adolescents set out at the second United Nations High-level Meeting on the Fight Against TB in 2023. Considering the latest WHO recommendations on drug-susceptible TB, drug-resistant TB and TB preventive treatment, recent developments in new TB medicines and formulations made available, results of clinical trials and studies, and advancements of key medicines in the TB R&D pipeline, WHO convened the second PADO-TB meeting (PADO-TB2) on 3–5 October 2023. This meeting report summarizes the proceedings, discussions and the main consensus-based outputs of the PADO-TB2 meeting: - PADO-TB2 priority list (priority formulations to be investigated/developed in the short term and essential formulations to be developed in the longer term) - PADO-TB2 watch list (promising candidates for investigation/development for children within 5–10 years) - Priority research questions.

The aim of this operational handbook is to provide practical guidance on the implementation of the World Health Organization (WHO) policy recommendations on the prevention and management of TB in children and adolescents under programmatic circumstances and at different levels of the health system. The practical guidance aims to inform the development or revision of national policies and related implementation guidance (e.g. handbooks, standard operating procedures) on the management of TB in children and adolescents. This handbook can also help countries adequately plan for the uptake of interventions to better address the specific needs of children and adolescents with or at risk of TB. It can contribute to national efforts to build capacity among national and subnational programme managers and among health workers at all levels of the health care system. The target audience for this handbook includes NTPs and other child health programmes that provide care for children with or at risk of TB, including maternal, newborn, child and adolescent health programmes, HIV services, and PHC programmes. The handbook also targets paediatricians and other health care workers (HCWs) in the public and private sectors, school health services, civil society and community-based organizations, and health care educators.

Tuberculosis (TB) strains with drug resistance (DR-TB) are more difficult to treat than drug-susceptible ones, and threaten global progress towards the targets set by the End TB Strategy of the World Health Organization (WHO). There is thus a critical need for evidence-based policy recommendations on the treatment and care of patients with DR-TB, based on the most recent and comprehensive evidence available. In this regard, the WHO consolidated guidelines on drug-resistant tuberculosis treatment fulfil the mandate of WHO to inform health professionals in Member States on how to improve treatment and care for patients with DR-TB. Between 2011 and 2018, WHO has developed and issued evidence-based policy recommendations on the treatment and care of patients with DR-TB. These policy recommendations have been presented in several WHO documents and their associated annexes, including the WHO treatment guidelines for multidrug- and rifampicin-resistant tuberculosis, 2018 update, issued by WHO in December 2018. The policy recommendations in each of these guidelines have been developed by WHO-convened Guideline Development Groups (GDGs), using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach to summarize the evidence, and formulate policy recommendations and accompanying remarks. The present Consolidated guidelines include a comprehensive set of WHO recommendations for the treatment and care of DR-TB, derived from these WHO guidelines documents. The consolidated guidelines include policy recommendations on treatment regimens for isoniazid-resistant TB (Hr-TB) and MDR/RR-TB, including longer and shorter regimens, culture monitoring of patients on treatment, the timing of antiretroviral therapy (ART) in MDR/RR-TB patients infected with the human immunodeficiency virus (HIV), use of surgery for patients receiving MDR-TB treatment, and optimal models of patient support and care.

WHO has published a global TB report every year since 1997. The main aim of the report is to provide a comprehensive and up-to-date assessment of the TB epidemic, and of progress in prevention, diagnosis and treatment of the disease, at global, regional and country levels. This is done in the context of recommended global TB strategies and targets endorsed by WHO?s Member States, broader development goals set by the United Nations (UN) and targets set in the political declaration at the first UN high-level meeting on TB (held in September 2018). The 2019 edition of the global TB report was released on 17 October 2019. The data in this report are updated annually. Please note that direct comparisons between estimates of TB disease burden in the latest report and previous reports are not appropriate. The most recent time-series of estimates are published in the 2019 global TB report.

These guidelines provide guidance on the diagnosis of human immunodeficiency virus (HIV) infection, the use of antiretroviral (ARV) drugs for treating and preventing HIV infection and the care of people living with HIV. They are structured along the continuum of HIV testing, prevention, treatment and care. This edition updates the 2013 consolidated guidelines on the use of antiretroviral drugs following an extensive review of evidence and consultations in mid-2015, shared at the end of 2015, and now published in full in 2016. It is being published in a changing global context for HIV and for health more broadly.
