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.

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.

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.

The National Asthma Education Programme (or NAEP for short) was started in 2008. We are a registered Non-Profit Organisation that aims to disseminate impartial information about asthma diagnosis and treatment to health professionals and the South African public.
Asthma:
• is one of the most common respiratory complaints in the world today.
• affects one in ten children (10%) and one in twenty adults (5%)
• can occur for the first time at any age, even in adulthood.
•usually begins before the age of five years. A few children affected will ...outgrow” it during their teenage years but it usually persists if contracted in adulthood.
• tends to run in families as do related allergic conditions like hay fever and eczema.
• cannot as yet be cured but if kept under control, those affected will be able to live normal lives enjoying full involvement in sport and all other activities.

Asthma is a common breathing condition that affects 20% of all children Asthma tends to run in families, although this is not always the case. You may have seen someone at school who uses an inhaler to help them breathe better and control asthma symptoms.
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!
Asthma is a chronic lung disease affecting people of all ages. It is caused by inflammation and muscle tightening around the airways, which makes it harder to breathe.
Symptoms can include coughing, wheezing, shortness of breath and chest tightness. These symptoms can be mild or severe and can co...me and go over time.
Although asthma can be a serious condition, it can be managed with the right treatment. People with symptoms of asthma should speak to a health professional.

How to detect signs of Asthma
Asthma is a long term illness of the lungs that causes the airways to become inflamed and produce lots of mucus. Viral infections, cold air, allergens, exercise, and smoke make the airways “twitchy”; they close easily causing asthma attacks with coughing, wheezing and shortness of breath (see wh...at is asthma). Between attacks the airways are inflamed (see what is an allergy).

Using an inhaler is the most common and effective way of taking asthma medicines. If you’re NOT using your inhaler correctly, you might not be getting the full dose of medicine your doctor or asthma nurse prescribed because the medicine can’t reach your
lungs. Instead it might be hitting the ba...ck of your throat, orstaying on your tongue or in your mouth where it won’t help atall.

Know How to Use Your Asthma Inhaler.
Using a metered dose inhaler (inhaler in mouth).
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.

There is no safe level of secondhand smoke exposure

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.
