Severe and difficult asthma in a low- and middle-income country (LMIC) can relate to lack of availability of basic medications; potentially reversible factors such as poor adherence or comorbidities such as obesity inhibiting a good response to treatment; and (rarely) true severe, therapy-resistant ...asthma. However, definitions of severity should encompass not merely doses of prescribed medication, but also underlying risk. The nature of asthmatic airway disease shows geographical variation, and LMIC asthma should not be assumed to be phenotypically the same as that in high-income countries (HICs). The first assessment step is to ensure another diagnosis is not being missed. Largely, political action is needed if children with asthma are to get access to basic medications. If a child is apparently not responding to low dose, simple medications, the next step is not to increase the dose but perform a detailed assessment of what factors (for example co-morbidities such as obesity, or social factors like poor adherence) are inhibiting a treatment response; in most cases, an underlying reason can be found. An assessment of risk of future severe asthma attacks, side-effects of medication and impaired lung development is also important. True severe, therapy-resistant asthma is rare and there are multiple underlying molecular pathologies. In HICs, steroid-resistant eosinophilia would be treated with omalizumab or mepolizumab, but the cost of these is prohibitive in LMICs, the biomarkers of successful therapy are likely only relevant to HICs. In LMICs, a raised blood eosinophil count may be due to parasites, so treating asthma based on the blood eosinophil count may not be appropriate in these settings.

The article discusses the education strategy of the International Primary Care Respiratory Group (IPCRG) for 2014–2020, focusing on building capacity to improve respiratory care globally. It highlights the significant burden of respiratory diseases and the role of primary care in addressing this i...ssue. The IPCRG aims to enhance educational efforts, support healthcare professionals, and foster knowledge-sharing among its member countries. The strategy includes developing teaching programs, promoting leadership, and using innovative educational methods, such as distance learning and "teach the teacher" programs. The overall goal is to improve clinical practice and outcomes in managing respiratory conditions through targeted education and collaboration.

The Indian Chest Society is a professional organization dedicated to promoting knowledge, research, and education in the field of pulmonology and respiratory diseases to enhance the diagnosis, treatment, and prevention of such conditions.
Chronic respiratory diseases, such as asthma and
chronic obstructive pulmonary disease, kill more than
four million people every year and affect hundreds
of millions more. These diseases erode the health
and well-being of the patients and have a negative
impact on families and societies. Women ...and
children are particularly vulnerable, especially those
in low and middle income countries, where they are
exposed on a daily basis to indoor air pollution from
solid fuels for cooking and heating. In high income
countries, tobacco is the most important risk factor
for chronic respiratory diseases, and in some of
these countries, tobacco use among women and
young people is still increasing.

This guideline covers diagnosing, monitoring and managing asthma in adults, young people and children. It aims to improve the accuracy of diagnosis, help people to control their asthma and reduce the risk of asthma attacks. It does not cover managing severe asthma or acute asthma attacks. It emphasi...zes the importance to include advice in the personalised
action plan on minimising indoor air pollution and reducing exposure to outdoor air pollution.

This articel summarises the evidence base underpinning supported self-management for asthma. It provides clinicians with a practical approach to providing supported self-management for asthma and suggests an appropriate strategy for implementing supported self-management.
Asthma is the most common chronic illness of childhood. The prevalence is rising and the mortality and morbidity from asthma are unacceptably high in South Africa. This article emphasizes the importance to make a correct diagnosis based, most importantly, on the clinical history and supported by inv...estigations. Further, the appropriate drug and device must be chosen to achieve good asthma control. It explains that patients must be followed up regularly and their asthma control must be assessed so that the treatment can then be adjusted according to the level of control. Additionally, Asthma education and adherence are important components of management of the condition.

Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, with airway reversibility. Management of chronic inflammation with anti-asthma medication improves asthma control and quality of life. The aim of this journal is to provide an eviden...ce-based approach for chronic asthma management in young children and adolescents and provide guidance on the use of new asthma drugs in children.
For that, the South African Childhood Asthma Working Group (SACAWG) convened in January 2017. The asthma treatment task group reviewed the available scientific literature and international asthma treatment guidelines. The evidence was then graded according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system and recommendations were made based on scientific evidence and local context. Asthma management recommendations were made for children ˂6 years of age and older children and adolescents, as well as for stepping up and stepping down of therapy. This review does not include biologics or novel asthma drugs, which are covered in another CME article in this edition of SAMJ.
The final conclusions are that it is important to ensure good response, treatment and adherence, type of medication, device and checking of technique are all critical. Stepping up of therapy should be done only after ensuring good adherence and technique. Once therapeutic response is achieved, medication administration has to be stepped down to improve ease of use and avoid unnecessary side-effects.

Diagnosing asthma in children represents an important clinical challenge. There is no single gold-standard test to confirm the diagnosis. Consequently, over- and under-diagnosis of asthma is frequent in children. A task force supported by the European Respiratory Society has developed these evidence...-based clinical practice guidelines for the diagnosis of asthma in children aged 5–16 years using nine Population, Intervention, Comparator and Outcome (PICO) questions. The task force conducted systematic literature searches for all PICO questions and screened the outputs from these, including relevant full-text articles. All task force members approved the final decision for inclusion of research papers. The task force assessed the quality of the evidence using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.
The task force then developed a diagnostic algorithm based on the critical appraisal of the PICO questions, preferences expressed by lay members and test availability. Proposed cut-offs were determined based on the best available evidence. The task force formulated recommendations using the GRADE Evidence to Decision framework.
Based on the critical appraisal of the evidence and the Evidence to Decision framework, the task force recommends spirometry, bronchodilator reversibility testing and exhaled nitric oxide fraction as first-line diagnostic tests in children under investigation for asthma. The task force recommends against diagnosing asthma in children based on clinical history alone or following a single abnormal objective test. Finally, this guideline also proposes a set of research priorities to improve asthma diagnosis in children in the future.

Although asthma is very common, affecting 5–10% of the population, the diagnosis of asthma in adults remains a challenge in the real world, which results in both over- and under-diagnosis. A taskforce was set up by the European Respiratory Society to systematically review the literature on the dia...gnostic accuracy of tests used to diagnose asthma in adult patients and provide recommendations for clinical practice.

Since there is no single objective diagnostic test for asthma this study suggests an approach of collecting and assembling pieces of clinical information to create a diagnostic picture, like making a jigsaw puzzle. These pieces should include demonstration of symptom and airway variability and/or br...onchodilator responsiveness over time, to support a clinical diagnosis.
