BACKGROUND. Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, as well as airway reversibility. The burden of asthma in children is increasing in low- and middle-income countries and remains under-recognised and poorly managed.
OBJE...CTIVES. To quantify the burden of asthma in the South African (SA) population and identify the risk factors associated with disease severity in the local context.
METHODS. The SA 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 epidemiology task group reviewed the available scientific literature and assigned evidence according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system.
CONCLUSIONS. Asthma in children remains a common condition, which has shown an increasing prevalence in urban and rural populations of SA. Of concern is that almost half of children in urban communities experience severe asthma symptoms, and many asthmatics lack a formal diagnosis and thus access to treatment. Exposure to tobacco smoke and living in highly polluted areas increase the severity of wheezing in young children.

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 2014, the International Study of Asthma and Allergies in Childhood (ISAAC) reported that the highest prevalence of symptoms of severe asthma was found in the low- and middle-income countries (LMICs), including Nigeria. While exposure to biomass fuel use may be an important risk factor in the deve...lopment of asthma, its association with asthma symptoms severity has not been well-established. The aim of this study is to extend the spectrum of environmental risk factors that may be contributing towards increasing asthma morbidity, especially asthma symptoms severity in rural schoolchildren in Nigeria and to examine possible asthma underdiagnosis among this population.

Air pollution from road traffic is a serious health hazard, and people with preexisting respiratory disease may be at increased risk. We investigated the effects of short-term exposure to diesel traffic in people with asthma in an urban, roadside environment.
Allergic rhinitis (AR) and asthma are inflammatory conditions of the airways that often occur concomitantly. This global survey was undertaken to understand patient perspectives regarding symptoms, treatments, and the impact on their well-being of comorbid AR and asthma.
The prevalence of asthma and allergic rhinoconjunctivitis is high in western countries, and has been rising throughout the late 20th century. However, relatively little is known about the prevalence of allergic disorders in children in North Africa and the Middle East, and even less is known about t...he relative importance of socioeconomic factors in its aetiology in these countries, when compared to Europe, the USA and Australia.

The National Asthma Education Programme (NAEP) is a registered non-profit organisation whose mission is to provide asthma education to healthcare professionals, patients and the lay public. It was founded in 1994 by Dr Mike Greenblatt and Profs Dave Luyt and Robin Green. This year NAEP celebrates it...s 25th anniversary and remains driven by the need to improve the daily lives of numerous asthmatics in South Africa (SA) and Africa.

Pollution (dirty air) is a big trigger for asthma as it makes it difficult to breathe and affects the health of humans, animals, and plants. Avoiding pollution helps prevent asthma symptoms!
An allergy is when someone has a bad reaction to something in the enviroment that other people can tolerate. We get allergies when our bodies defence system hurt us instead of protecting us.
When someone is having an asthma attack, their airways go into spasm which causes tightness of the chest; the linings of the airways become inflamed and phlegm is produced further obstructing the airways and leading to severe difficulty in breathing (Fig. 1). Asthma does lead to fatalities and shoul...d always be taken seriously.

The prevalance of asthma an allergy, defined as immunologically mediated hypersensitivity, is increasing. It is estimated that over 20% of the world population suffers from IgE-mediated allergic disease, such as allergic asthma, allergic rhinitis and allergic conjunctivitis, atopic eczema/atopic der...matitis, and anaphylaxis. Asthma, which in more than 50% of adults and in at least 80% of affected children is allergic, occurs in around 5-15% in the paediatric population. Asthma it estimated by the World Health Organization (WHO) to affect about 150 million people worldwide, placing an enormous strain on health resources in many countries, and is a major cause of hospitalizations for chronic diseases in children in the western wolrd.
Information may be derived from areas where a rapid increase in disease has occured, to from the basis for prevention strategies in areas where the prevalence of these diseases is still low. Where current expert opinion is still divided, where future research is required, or studies have provided negative results, the available information may prevent the implementation of unnecessary, restrictive, and costly avoidance strategies.

The increasing prevalence of childhood asthma in the developed world is a cause for concern. A so-called Western lifestyle has been the factor most commonly cited to explain this worrying increase in asthma prevalence. Early studies in a limited number of African countries showed a very low rural pr...evalence of childhood asthma, especially where children lived according to a traditional lifestyle. These same studies showed that asthma was not uncommon in urbanized African children. There has been an
increasing tendency over the past 20 years for those in rural communities to move to the large urban centers. This article analyses the urban-rural differences and factors that influence the development of asthma in susceptible children.

Coronavirus disease 2019 has a mild disease course in children and adolescents. Chronic respiratory conditions, including asthma, have been suggested as risk factors; however, asthma in children is highly variable in both triggers and severity.
During the pandemic, pediatric asthma services limite...d consultations and established virtual clinics. However, respondents perceived their patients’ asthma control to be retained or even improved, while treatment adherence was considered increased. Children with asthma were not disproportionately affected by coronavirus disease 2019.
Trigger avoidance and treatment adherence can rapidly improve asthma control in children, even under lockdown pressure. Children/adolescents with asthma do not appear to need additional prophylactic measures from coronavirus disease 2019 when asthma is well-treated. This article analyses the effect of COVID-19 on Asthma in children, providing information for management guidelines.
