History

The development and evolution regarding COPD (emphysema) covers a few centuries. 

In the past, what was understood about  emphysema and the cause of the disease? How has our understanding towards emphysema developed over the time?

Some of the early discoveries include :

      In 1814, Charles Badham used the wordcatarrh’ (disorder of  inflammation of the mucous membranes in one of the airways or cavities of the body) to refer to chronic cough and mucus hypersecretion. Badham described chronic bronchitis as disabling disorders.
      René Laennec, a clinician, pathologist as well as a physician, described emphysema in A treatise on the diseases of the chest, as below:

            “The disease which I designate by this title is very little known and has not hitherto been correctly described by any author. I for a long time thought it very uncommon, because I had observed only a few cases of it: but since I have made use of the stethoscope, I have verified its existence as well on the living as the dead subject, and am led to consider it as by no means infrequent. I consider many cases of asthma, usually deemed nervous, as depending on this cause. The chief reason of this affection having been so completely overlooked is, that it is in some sort merely the exaggeration of the natural condition of the viscus. ”

              “In opening the chest, it is not unusual to find that the lungs do not collapse, but they fill up the cavity completely on each side of the heart. When experienced, this will appear full of air . . . . The bronchus of the trachea are often at the same time a good deal filled with mucous fluid.”


            He dissected patients he studied during his life, and found out that emphysema lungs were hyperinflated and did not empty well. Laennec was also the inventor of stethoscope in 1816.

   The invention of spirometer in 1846 by John Hutchinson gave rise to effective means of identification and assessment of the course of COPD and responses to therapy. However, it is underused.

      William Osler, who was called the Father of modern medicine, believed that emphysema was caused by excessive pressure in the alveoli. However, in Osler’s Principles and practices of medicine (1916), no mention on spirometer was included.




BONUS : The 1973 edition of "Diagnosis and Treatment" (a standard medical textbook), states that emphysema is a disease which involves destruction of the alveolar(lung) tissue but the cause is unknown, although "many doctors" think it is caused by "cigarette smoking". Some time subsequent to 1973, a genetic cause of emphysema was discovered.


Similar to the prediction back in the past, smoking is the leading cause of emphysema as cigarette contains irritants which will damage the lungs and airways. Other factors are also associated with long-term exposure to airborne irritants, such as:


1. Tobacco smoke


2. Marijuana smoke



3. Air pollution



4. Manufacturing fumes



5. Coal and silica dust


Inhalation and breathing in of these irritants over a long period of time inflame and narrow the airways. Elastic fibres that are responsible for the elasticity of the lungs are destroyed, affecting its ability to stretch. A person who has had frequent and severe lung infections, especially during childhood, may have a greater chance of developing lung damage that can lead to emphysema.

Alpha-1 Antitrypsin deficiency is a rare, inherited cause of emphysema. Alpha-1 Antitrypsin is a protein that protects the elastic structures in the lungs. It keeps white blood cells from damaging normal tissues. The condition of a smoker with Alpha-1 Antitrypsin deficiency is much worse than a non-smoker as emphysema progresses faster. People with Alpha-1 Antitrypsin develop emphysema at a younger age compared to smokers.


Do you know?

About 2 out of every 1,000 people have an alpha-1 antitrypsin deficiency. People who smoke and have Alpha-1 Antitrypsin deficiency are almost certain to develop emphysema.

Frequent use of cooking fire without proper ventilation is also a risk factor for emphysema.

  4. I'm 59 years old and female. I was diagnosed a couple of years ago with COPD and I was beyond scared! My lung function test indicated 49% capacity. After having had flu a year ago, the shortness of breath, coughing and chest pains continued even after being treated with antibiotics. I've been smoking two packs a day for 36 years. Being born without a sternum caused my ribs to be curled in just one inch away from my spine, resulting to underdeveloped lungs. At age 34 I had surgery and it was fixed. Unfortunately my smoking just caused more damage to my already under developed lungs. The problem was having is that I enjoy smoking and don't want to give up! Have tried twice before and nearly went crazy and don't want to go through that again. I saw the fear in my husband and children's eyes when I told them about my condition then they start to find solution on their own to help my condition.I am an 59 now who was diagnose COPD emphysema which I know was from my years of smoking. I started smoking in school when smoking was socially acceptable. I remember when smoking was permitted in hospitals. It was not known then how dangerous cigarettes were for us, and it seemed everybody smoked but i was able to get rid of my COPD lung condition through the help of total cure herbal foundation my husband bought, totalcureherbsfoundation .c om has the right herbal formula to help you get rid and repair any lung conditions and cure you totally with their natural organic herbs,it class products at affordable prices.
