What is Asthma COPD Overlap Syndrome?

Asthma COPD Overlap Syndrome (ACOS) is when you have same symptoms of both asthma and COPD. A new concept was introduced, which is intended to describe a special variant of chronic lung diseases. The intention is to give a name to a phenomenon which is a mixture of the symptoms of asthma and the symptoms of COPD (chronic obstructive pulmonary disease).


There are 3 main conditions Asthma,Emphysema and Chronic bronchitis fall under the COPD umbrella.The main symptoms of COPD such as shortness of breath, chest tightening,Wheezing,mucus production, and an ongoing cough are progressive players.you may have regular symptoms of COPD and also experience flare ups.

What are differences of Asthma and COPD?

Asthma and COPD are grouped by chronic lung diseases, but actually both of them are different. Asthma is a disease that can cure and normalize. It is different from COPD, a chronic disease that is not cured. And no way back to normal. We call these two groups.

  1. Asthma: Reversible obstructive airway disease

Asthma pathophysiologyis located only in the airways. When patient is exposed to dust, pollution or triggers. It makes airway inflammation causes of airflow obstruction.

  1. COPD: Irreversible airway disease

COPD pathophysiology is not just located in the airways. It’s also including alveoli, which is usually caused by the patient’s recurring exposure to smoke or pollution from their jobs. It makes both of airways and alveoli loss performance, normally the airways will extract with radial traction while exhaling. The air in the air bag can be released and the alveoli will have an elastic recoil wish is also pressure of the air by itself. When the airways loss performance. It could not be fully stretch out of the air and the alveolus does not push the air out. Keep the wind in the lungs. It makes disease is called emphysema.

What are similar symptoms of Asthma and COPD?

Asthma and COPD are symptoms include:

How to diagnosis ACOS ?

In a certain percentage of patients, it is not possible to clearly distinguish the diagnosis of asthma and COPD. In these patients, the disease pattern neither matches the classical asthma nor the classical COPD, because they show facets that fit both COPD and asthma. These patients are now increasingly diagnosed with “Asthma-COPD Overlap Syndrome” (ACOS).

This patient group includes, for example, Patients with a COPD who had previously been diagnosed with asthma. Patients who first receive the diagnosis COPD and who then show clear indications for an allergy in later life may fall into this patient group.

What are differences symptoms of ACOS ,COPD and asthma?

According to current data, ACOS patients are heavier than patients with COPD or only asthma. Patients with ACOS have more severe symptoms and it is more common to exacerbation. This means that ACOS patients also need to go to the hospital more often.

How often is Asthma COPD Overlap Syndrome (ACOS)?

Basically,Asthma COPD overlap syndrome (ACOS) is very difficult to estimate how often of severe symptoms. because the range of study results is very large. There are examinations that affect up to 50 percent of patients with asthma COPD overlap syndrome (ACOS).

The reasons for wide range of examination results are that they have used very different definitions in each case. There is currently no generally binding definition of asthma COPD overlap syndrome (ACOS) and thus many studies remain difficult to compare.

Some of doctor start from 10 %to a maximum of 20 % of patients whose obstructive pulmonary disease is not accurately assigned to one of the diagnoses asthma or COPD.Relatively many patients are affected.

The term “mixture” of asthma and COPD as asthma COPD overlap syndrome (ACOS),It mean”confusion potential”.

What disease comes first, COPD or Asthma?  

   In the majority of patients diagnosed with asthma-COPD overlap syndrome (ACOS) currently, COPD has been diagnosed, and in the past, they have had asthma.

Background: Asthma is typically a disease of the younger age, whereas COPD is a classic disease of later life – COPD patients under 40 years are rare. For this reason it is usually the asthma disease that precedes the COPD.

What is the No.1 Risk Factor of ACOS?

The No.1 risk factor Of asthma-COPD overlap syndrome (ACOS) is smoking. COPD and ACOS are linked to smoking.It  mean COPD and ACOS can prevent by quit smoke or avoid second hand smoke.

In other countries such as India, South America or Central America, this is different. There is high biomass exposure, .It is cooked a lot at the open fire and without a fireplace, and many people show a COPD like disease, without a history of smoking. About 2 billion people are affected worldwide!

What other diseases that can occur in Asthma, COPD and ACOS?

Both asthma and COPD can be associated with further commodities. In asthma, the patients have e.g. Often problems with the upper respiratory tract and also a gastroesophageal reflux can play a role in asthma patients.

COPD is often associated with cardiovascular disease, osteoporosis and the metabolic syndrome, that is, These typical commodities are a reflection of the risk factors for COPD itself.

With ACOS there is no clear statement in the literature on this question. However, It would start from similar co-morbidities similar to asthma or COPD.

How are COPD and ACOS Diagnosed?

      Patients with COPD or ACOS have irreversible bronchial obstruction, which can be determined by a pulmonary function test. In the acute test or called lysis test, the patient is given a bronchodilatory drug, typically salbutamol, which normally “opens” the bronchi in asthma. However, this effect is only partially present in COPD patients or ACOS patients.

Can we take COPD Bronchodilator Medicines for ACOS Treatment?

In the COPD, there are primarily drugs that dilate the bronchi.

    The case of asthma, an inhalable corticosteroid, which combats the inflammation, may be presumed, possibly in conjunction with a long-acting betamimetic, which is also intended to dilate the bronchi.

There are indications of an ACOS, treated primarily with asthma with an inhalable corticosteroid, combined with a long-acting ß-mimetic. Possibly, the treatment can be supplemented by a further bronchial extender, a so-called long-acting anticholinergic, which is often used in COPD.
