How Do Steroids Help Asthma
The steroids used to treat asthma are known as corticosteroids. Corticosteroids are copies of hormones your body produces naturally.
Steroids help asthma by calming inflamed airways and stopping inflammation. This helps ease asthma symptoms such as breathlessness and coughing. It will also help prevent your lungs reacting to triggers.
Youre more likely to avoid high doses of steroids if you take your preventer inhaler every day as prescribed, says Dr Andy Whittamore, Asthma UKs in-house GP.
Clinical Application In Asthma Patients
ICS are now recommended as first-line therapy for all patients with persistent symptoms. ICS should be started in any patient who needs to use a ß2-agonist inhaler for symptom control more than three times weekly. It is conventional to start with a low dose of ICS and to increase the dose until asthma control is achieved. However, this may take time and a preferable approach is to start with a dose of corticosteroids in the middle of the dose range to establish asthma control. Once control is achieved the dose of inhaled corticosteroid should be reduced in a step-wise manner to the lowest dose needed for optimal control. It may take as long as three months to reach a plateau in response and any changes in dose should be made at intervals of three months or more. When daily doses of 800 µg daily are needed a large volume spacer device should be used with a metered dose inhaler and mouth washing with a dry powder inhaler in order to reduce local and systemic side effects. ICS are usually given as a twice daily dose in order to increase compliance. When asthma is unstable four times daily dosage may be preferable .
The Set Mnemonic For Asthma
When providing education for asthmatics, in the respiratory field we use the SET mnemonic. SET stands for Swelling, Excess mucus, and Tightness. These are the three main things that happen during an asthma flare-up or asthma attack. Inflammation in the lungs is what causes the swelling which makes it difficult to breathe. Mucus production is increased and when combined with the swelling and tightness, causes wheezing. Tightness happens from both the swelling and bronchospasm. These three things create a perfect storm when you are exposed to a trigger.

Why Might You Need Long Term Oral Corticosteroids
If you have severe asthma, you might be prescribed oral corticosteroids long term. This could be months or even years. Your doctor or specialist will only prescribe this if it is necessary to prevent you from having regular flare-ups.
If you are prescribed long term oral corticosteroids, ask your doctor or specialist if any monoclonal antibodies are suitable for you. Monoclonal antibodies could reduce or eliminate your need for long term oral corticosteroids.
What Is Ocs Overexposed
OCS Overexposed is a national education campaign developed in collaboration with more than 10 patient advocacy and medical societies to raise awareness of appropriate OCS use and reveal OCS overuse for what it often is a treatment plan that is no longer working. The campaign has also developed the Oral Corticosteroid Stewardship Statement.
There are several asthma assessment tools you can use to determine if your asthma is in control or not:

Current Treatment Of Acute Asthma
Acute asthma exacerbations are defined as episodes of progressive increase in shortness of breath, cough, wheezing, or chest tightness, or some combination of these symptoms. Most recently, an expert group formed by the National Institutes of Health agreed to define acute asthma as a worsening of asthma requiring the use of systemic corticosteroids to prevent a serious outcome. Acute exacerbation of asthma symptoms is a common complication of the disease. The frequency in which exacerbations happen vary widely depending on the severity of disease, the degree of control with prophylactic medications, and exposure to triggers. In a multicenter study from the US, the admission rate of all comers to the emergency department with acute asthma was 23%. On the other hand, a European study showed that only about 7% of all patients with acute asthma exacerbation required hospitalization. We have a similar experience in Saudi Arabia where about 8% of all asthmatics with acute exacerbation are hospitalized, but if we look at only the severe group the rate goes up to 40%. These epidemiological data underscores the importance of effective treatment of asthma exacerbations and their prevention.
Delayed Effects Of Corticosteroids On The Airway Vasculature
Corticosteroids interact with the vasculature to maintain and, in excess, enhance vascular tone . Impaired production of endogenous corticosteroids in various medical conditions is commonly associated with systemic hypotension. In contrast, corticosteroid administration or overproduction of endogenous corticosteroids is thought to induce systemic hypertension, partially by increasing peripheral vascular tone. The vascular effects are largely mediated through genomic mechanisms, and thus occur with a delay of hours or days.
In asthma, inhaled corticosteroids have been shown to counteract all the vascular manifestations of airway inflammation by acting directly on vascular smooth muscle or endothelium, or indirectly by inhibiting the release of vasoactive inflammatory mediators , . Because disease severity seems to correlate with airway vascular changes in patients with asthma, these genomic vascular actions of inhaled corticosteroids may be of therapeutic value and have recently received increased interest .

What Are Oral Corticosteroids For Asthma
Oral corticosteroids , often referred to as oral steroids, is a medicine to treat severe or uncontrolled asthma. Oral corticosteroids, also know as oral steroids, are available in pill or liquid form. Oral steroids are not the same as anabolic steroids used in body building or inhaled corticosteroids , which have fewer risks.
Introduction And Evolution Of Corticosteroids In The Management Of Asthma: Historical Background
Shortly after the discovery of the structure of adrenal steroid hormones, Hench et al. examined using cortisone to treat arthritis in 1949. The effect was remarkable and that work won the Nobel Prize the next year. It also started a series of trials of corticosteroids in various inflammatory conditions. The first use of corticosteroid to treat acute asthma exacerbation was in 1956. Development of corticosteroids that have less mineralocorticoid activity, like prednisone, and later those that have no mineralocorticoid activity, like dexamethasone, made corticosteroids more attractive therapies to use in asthma. In 1972, Clark showed for the 1st time that inhaled beclomethasone was effective in the management of asthma with less adverse effects than systemic steroids. Numerous reports came afterwards describing the efficacy of oral prednisone and prednisolone , IV methylprednisolone and ICS such as triamcinolone, budesonide, and fluticasone in the management of asthma. These effects are mediated through various genomic and nongenomic mechanisms. shows some common systemic corticosteroids and their relative potency.

What Are The Side Effects Of Oral Steroids Used For Asthma
While oral steroids are often prescribed for severe asthma and has benefits, overuse of OCS can jeopardize long-term health.
OCS use has a cumulative effect on a person over their lifetime and overreliance can cause significant side effects. These include:
- Weight gain, high blood sugar, can trigger or worsen diabetes
- Increased risk of infections
- Thin skin, bruising and slower wound healing
- Mood swings, depression, aggressive behavior
People using OCS should be aware of and watchful for side effects and always discuss any side effects with their physician once therapy is started. People with asthma should also:
- Ask their doctor for a blood test to determine their type of asthma
- Find out if alternative treatments are available · Balance the risks vs. benefits of taking OCS in a with their doctor
Pooled Analysis: Adrenal Insufficiency Per Condition
Meta-analysis, adrenal insufficiency per dose and duration in asthma patients.
Analysis per treatment dose and treatment duration was performed in asthmatic patients only for reasons of population homogeneity. Use of corticosteroids in low, medium, or high doses resulted in a percentage of adrenal insufficiency of 2.4% , 8.5% , and 21.5% , respectively. Use of corticosteroids for a short, medium, or long term resulted in a percentage of adrenal insufficiency of 1.4% , 11.9% , and 27.4% , respectively.
If performed in asthma patients using inhaled corticosteroids only, the percentages of adrenal insufficiency in low, medium, and high doses were 1.5% , 5.4% , and 18.5% , respectively. In short-, medium-, and long-term treatment duration groups, percentages of adrenal insufficiency were 1.3% , 9.0% , and 20.3% , respectively .

For Severe Persistent Asthma
When used as a controller medicine, the daily dose of oral steroids is prescribed based on the following recommended ranges in adults:
- Prednisone: 5 mg to 60 mg per dayï»¿ï»¿
- Prednisolone: 5 mg to 60 mg per dayï»¿ï»¿
- Methylprednisolone: 4 mg to 50 mg per dayï»¿ï»¿
- Dexamethasone: 0.75 mg to 10 mg per dayï»¿ï»¿
The recommended dose in children is calculated at roughly 1 mg/kg per day for prednisone, prednisolone, and methylprednisolone. Dexamethasone is calculated at 0.3 mg/kg per day.
It is always best for those with severe persistent asthma to start with the lowest possible dose of oral corticosteroids and to only increase the dose if symptoms are not effectively controlled. An overdose of these medications can lead to vomiting, weakness, seizures, psychosis, and severe heart rhythm disruptions.ï»¿ï»¿
Once treatment is started, it can take up to two weeks before the full benefits are felt.

History Of Oral Corticosteroids Use In Asthma
Before the 1950s, the treatment for asthma was restricted to those compounds that were either plant-derived or adrenaline derivatives. This treatment consisted primarily of bronchodilator agents.4 With the development of steroid and adrenocorticotropic hormone extracts, a 1952 seminal study by McCombs noted the marked improvement that could be derived with respect to asthma symptoms and control using either corticosteroids or adrenocorticotropic hormone.5 It has since been determined that oral and parenteral corticosteroids have no significant difference in bioavailability, and thus oral corticosteroids are by far the most common formulation of systemic corticosteroid used in the treatment of asthma today. It was not until 1958 that the association between successful treatment with OCS and a reduction in eosinophils in the sputum was noted.6 This revelation opened the door to widespread treatment with OCS, both on a chronic and acute basis,4 but with this came increasing recognition of the side effects of systemic corticosteroids. The subsequent development of inhaled corticosteroids and the recognition that these can be equally as effective in the majority of patients with asthma, therefore, led to a decline in the use of OCS, except in the population with severe asthma.7

Do They Affect Other Medicines
Studies show that corticosteroids also increase the number of beta 2 receptors lining airways, making beta agonist medicines like albuterol work better. 1 The combination of this and anti-inflammatory effects work to prevent asthma attacks, or make them less severe and easier to control when they do occur. By the late 1980s, researchers understood that daily use of inhaled corticosteroids helped many asthmatics obtain ideal asthma control. This gave birth to the term asthma controller medicine. ICS remain the most commonly prescribed asthma controller medicine.
If You Miss A Dose Or Take Too Much
If you forget to take a dose, take it as soon as you remember. If it’s nearly time for your next dose, skip the one you missed.
Do not take a double dose to make up for a forgotten dose.
Accidentally taking too many puffs from a steroid inhaler is unlikely to be harmful if it’s a one-off. Speak to a doctor, nurse or a pharmacist if you’re worried.
Using a steroid inhaler too much over a long period can increase your chances of getting side effects.

Regression Of Airway Blood Vessels
Corticosteroids have a potential therapeutic role of reversing components of airway remodelling in asthma. This has been tested in some recent studies using monoclonal antibodies against type IV collagen to identify blood vessel in bronchial specimens obtained from asthmatic patients. In a cross-sectional study, therapy with inhaled beclomethasone dipropionate has been shown to be associated with a reduced area of the lamina propria occupied by vessels however, the number of vessels decreased only in patients on high doses of the inhaled corticosteroid . Based on interventional studies, the inhaled daily doses and the length of therapy seem to be the critical determinants of the vascular effects of inhaled corticosteroids. Furthermore, the inhibitory effects on the remodelling process seem to occur only with long-term therapy with corticosteroids. Whereas a 6-month treatment with a daily dose of 800µg beclomethasone dipropionate reduced the number of blood vessels and the vascular area , a 6-week treatment with fluticasone propionate was only effective at a daily inhaled dose of 1000µg, and not at 200µg, to reduce significantly the number of blood vessels and the vascular area . Moreover, in patients with asthma receiving a daily dose of 4001000µg of inhaled corticosteroid , adding of a daily dose of 200µg fluticasone propionate has not shown any effect on airway vascularity .
Carrying A Steroid Card
If youre taking high doses of steroids, or if youre on them for more than three weeks, youll need to carry a steroid card. This will have information on your dose and how long youve been taking them for.
Your doctor, rheumatology nurse or pharmacist should give you a steroid card if you need one. Make sure any change to your dose of steroid is updated on the card.
Steroid treatment can stop the body producing natural hormones, which can be dangerous if you get ill, have an accident or need an operation. Keeping the card with you will help any other doctor who treats you to manage your care correctly.
If you have any questions or concerns about this, talk to the healthcare professional who prescribed your steroids.

Corticosteroid Inhalers Hit The Market
The first ICS were approved for sale during the early 1980s. They were prescribed for many asthmatics, although some physicians, especially pediatricians, were reluctant to prescribe them except during acute asthma episodes. Once you felt better you were told to stop using them. This was probably a precautionary strategy based on the 1950s scare.
Possible Side Effects Of Oral Corticosteroids
Side effects are more likely if youre on long-term oral corticosteroid tablets, compared to if you only take a short course when your symptoms get worse. Your doctor will be aware of the possible side effects of steroid tablets and will monitor the doses and medicines you need for your asthma. To reduce the risk of side effects, your doctor will keep you on the lowest possible dose of steroid tablets.
Side effects associated with short term use include:
- Mood changes
- changes to the immune system
- changes in behaviour
- changes in the eyes.
- changes in bone which can result in an increased chance of fractures due to brittleness or softening of the bone
- changes in hormone levels in your body
- changes in the bodys ability to handle glucose
- effects on the parathyroid and thyroid glands which control calcium and body metabolism
- increased amounts of cholesterol in the blood
- increased blood pressure
Some of these changes can only be detected by a doctor, so if you are on long-term oral corticosteroids your doctor may arrange extra monitoring.
Please discuss all side effects with your doctor.
