Respiratory Bronchiolitis Interstitial Lung Disease

Do you suffer from RB-ILD? – Respiratory Bronchiolitis Interstitial Lung Disease (also referred to as RB-ILD) is perhaps one of the most well-known types of interstitial lung disease – this is due to the fact that it is a smoking related interstitial lung disease. According to various studies done by a large number of health officials, more than 1 billion of people in all parts of the world smoke and a shocking number of 5 billions of people die from illness that are related to tobacco each year.

This disease is known to be closely related to bronchiolitis – however, various clinical findings point out that that this disease is more life threatening than the former as it shows a horrific severity. Keep reading to learn more about this type of interstitial disease.

What is Respiratory Bronchiolitis ILD?
Histologically, respiratory bronchiolitis associated interstitial lung disease can be characterized by the presence of submucosal inflammation which is manifested by brown-pigmented macrophages. The brown pigmented macrophages are known as a result of an increased iron content which is rampant in heavy smokers. However, it is worth noting that the increased iron content is not the only culprit of the respiratory bronchioles’ and membranous’ submucosal inflammation – another factor such as the bronchioles’ and the alveoli’s metaplastic cuboidal epithelium is also responsible for this condition.

Interestingly enough, similar findings are said to also occur in drug reactions, mineral dust exposure over a period of time, as well as hypersensitivity reactions.

RB-ILD, Desquamative interstitial pneumonia similar and diagosis
One of the questions that is often asked is whether or not RB-ILD and Desquamative interstitial pneumonia are one and the same. The short answer is no. Histologically, they may resemble one another. However, this cannot be further from the truth. In RB-ILD, we may notice that the inflammation that occurs is not at all similar to that of desquamative interstitial pneumonia.

This is dues to the fact that in RB-ILD, the inflammation is seen to be much less extensive and is much more patchy when compared to Desquamative interstitial disease. The similarity of these two conditions prompt pulmonologists to highlight that the two diseases are two different manifestations of the same cigarette smoking-related disease.

To find out whether or not you suffer from RB-ILD, you must undergo a series of biiopsy and imaging test. Only then will your pulmonologists be able to see whether there’s a thickened bronchial wall, diffused nodular opacities, peripheral ring-shadows present and determine if you suffer from Respiratory Bronchiolitis Interstitial Lung Disease.
