COPD in 2018: syndrome or disease - first steps to new classification

New article from ERJ Open Research by Celli and Agusti is dedicated to hot topic in COPD: new classification with absolutely fresh approach!
Due to well-conducted epidemiological studies and advances in genetics, molecular biology, translational research, the advent of computed tomography of the lungs and bioinformatics, the diagnosis of chronic obstructive pulmonary disease (COPD) as a single entity caused by susceptibility to cigarette smoke is no longer tenable. Furthermore, the once-accepted concept that COPD results from a rapid and progressive loss of lung function over time is not true for a sizeable proportion of adults with the disease. Now we know that some genetic predisposition and/or different environmental interactions (nutritional, infectious, pollution and immunological) may negatively modulate post-natal lung development and lead to poorly reversible airflow limitation later in life, consistent with COPD.

We believe it is time to rethink the taxonomy of this disease based on the evidence at hand. To do so, we have followed the principles outlined in the 1980s by J.D. Scadding who proposed that diseases can be defined by four key characteristics: 1) clinical description (syndrome), 2) disorder of structure (morbid anatomy), 3) disorder of function (pathophysiology) and 4) causation (aetiology).

Here, we propose a pragmatic approach to the taxonomy of COPD based on different processes that result in a similar syndromic presentation. It can accommodate changes over time, as the pathobiology that may lead to COPD expands. We hope that stakeholders in the field may find it useful to better define the patients now boxed into one single entity, so that specific studies can be designed and conducted for each type of COPDs.

  1. Chronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long-term breathing problems and poor airflow. Tobacco smoking is the most common cause of COPD, with factors such as air pollution and genetics playing a smaller role. Find what is copd treatment

    1. I was diagnosed in early 2013 with COPD (chronic obstructive pulmonary disease) but l can now see the symptoms back 3 or 4 years earlier. I crashed and ended up in the hospital the end of February 2014. My husband would not bring me home without oxygen so a doctor there gave us one. I have had it ever since not until i found Total Cure Herbal Foundation.When we went for an appointment, after sitting around for an hour or so a COPD surviver walk by who use this herbal formula and cure her permanently,i contacted them immediately and purchased from them,i started the usage which last for 15 weeks...all the symptoms is total terminated,am fully cured of copd disease so do not hesitate to contact them on : ( https://totalcureherbalfou5.wixsite.com/herbal/contact )
