Non-communicable diseases (NCDs) are major global public health concerns that cause nearly three-quarters of the burden of mortality worldwide. Cardiovascular diseases, cancer, chronic respiratory diseases, and diabetes alone account for over eight out of ten NCD deaths. To alleviate this huge burde...n, the Sustainable Development Goals (SDG) aimed to reduce premature mortality from non-communicable diseases by one-third.

he aetiology of asthma and allergic disease remains poorly understood, despite considerable research. The International Study of Asthma and Allergies in Childhood (ISAAC), was founded to maximize the value of epidemiological research into asthma and allergic disease, by establishing a standardized m...ethodology and facilitating international collaboration. Its specific aims are: 1) to describe the prevalence and severity of asthma, rhinitis and eczema in children living in different centres, and to make comparisons within and between countries; 2) to obtain baseline measures for assessment of future trends in the prevalence and severity of these diseases; and 3) to provide a framework for further aetiological research into genetic, lifestyle, environmental, and medical care factors affecting these diseases. The ISAAC design comprises three phases. Phase 1 uses core questionnaires designed to assess the prevalence and severity of asthma and allergic disease in defined populations. Phase 2 will investigate possible aetiological factors, particularly those suggested by the findings of Phase 1. Phase 3 will be a repetition of Phase 1 to assess trends in prevalence.

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.

In the European Union, over 20 million people suffer from asthma. During the 1990s there was a rapid decrease in asthma mortality, probably related to the increased use of inhaled corticosteroids (ICS). However, during the last decade, asthma mortality rates have plateaued, and a consistently high p...roportion of patients have uncontrolled asthma. As a result, many patients with asthma still have impaired quality of life and suffer from chronic respiratory symptoms, often including night-time symptoms, causing sleep disturbance, excessive daytime sleepiness and decreased work productivity.

Asthma, hay fever and eczema are three common chronic conditions. There have been no recent multi-country data on the burden of these three conditions in adults; the aims of this study are to fill this evidence gap.
The Global Asthma Network Phase I is a multi-country cross-sectional population-bas...ed study using the same core methodology as the International Study of Asthma and Allergies in Childhood Phase III. It provides data on the burden of asthma, hay fever and eczema in children and adolescents, and, for the first time, in their parents/guardians.

asthma is a chronic inflammatory and a heterogeneous condition of respiratory system whose pathogenesis is linked with variable structural changes. The clinical manifestation of asthma includes attacks of breathlessness, cough, chest tightness and wheezing. Provision of basic equipment and test for ...asthma diagnosis and access to essential medicines by asthmatic patients reduces morbidity and mortality rates. Significant progress has been made in the diagnosis and management of asthma in other countries but not in the health care delivery system in Zimbabwe. Therefore, the aim of this study was to develop algorithm for asthma diagnosis and management for Zimbabwe.

A worldwide increase in the prevalence of asthma has been reported in recent years. With an increase in prevalence comes an increased burden of disease in terms of morbidity, mortality and compromised quality of life. The economic burden in terms of utilisation of healthcare resources and limitation... of the earning capacity of the individuals and families is an added problem. Various indicators such as disability-adjusted life years and healthy life years have been used to define the economic burden. The data from Asian countries regarding these parameters is scarce, underlining the need for systematic studies in these countries, especially those that are resource poor. The purpose of this review is to highlight the varying prevalence of asthma in Asia and to assess the likely economic burden for the future.

It is estimated that as many as 300 million people of all ages, and all ethnic backgrounds, suffer from asthma and the burden of this disease to governments, health care systems, families, and patients is increasing worldwide. In 1989 the Global Initiative for Asthma (GINA) program was initiated in ...an effort to raise awareness among public health and government officials, health care workers, and the general public that asthma was on the increase. The GINA program recommends a management program based on the best available scientific evidence to provide effective medical care for asthma tailored to local health care systems and resources.

Globally, it is estimated that 1 billion people suffer from acute and chronic respiratory conditions, making them major causes of illness and death. Although there is a relative lack of data and evidence on lung diseases beyond tuberculosis (TB) in Sub-Saharan Africa (SSA), their estimated regional ...burden is large and growing. In addition, there is a poorly understood relationship between infections, such as TB, and non-infectious causes of lung health problems. The problem in lung diseases in SSA is exacerbated by many factors, including under-prioritisation, under-treatment and weak preventative measures.

You can’t cure asthma. However, you can take steps to control the disease and prevent its symptoms. For example:
-Learn about your asthma and ways to control it
-Follow your written asthma action plan
-Use medicines as your doctor prescribes (Here’s how to use your inhaler device)
-Identif...y and try to avoid things that make your asthma worse
-Keep track of your asthma symptoms and level of control
-Get regular checkups for your asthma

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.

a "risk factor" is something that increases your chances of getting a disease or condition. In the case of asthma there are two diffrent type of risk factors. There are risk factors for developing asthma , and there are separate risk factors for those who already have asthma getting a severe asthma ...attack. We like to refer to the second as "triggers for asthma attacks" instead of "risk factors" to avoid confusion.

Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, as well as airway reversibility. The diagnosis of asthma in young children is limited by the inability to perform objective lung function testing in this group of patients and the wi...de variety of conditions that can phenotypically present with asthma-like symptoms.
This article provides an evidence-based approach for clinicians to accurately diagnose asthma in young children and to assess the level of control to guide therapeutic decisions.
The South African Childhood Asthma Working Group (SACAWG) convened in January 2017 with task groups, each headed by a section leader, constituting the editorial committee on assessment of asthma epidemiology, diagnosis, control, treatments, novel treatments and self-management plans. The asthma diagnosis and control task groups reviewed the available scientific literature and assigned evidence according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system, providing recommendations based on current evidence.

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.
