Difference Between COPD and Pulmonary Fibrosis

COPD is chronic obstructive Pulmonary  disease where airflow becomes very limited. Pulmonary  Fibrosis  is where the tissue in the lungs becomes scarred.

 

What is COPD?

Definition of COPD:

COPD is a chronic obstructive Pulmonary  disease in which the airflow is greatly limited, and it often consists of both symptoms of emphysema and bronchitis. People struggle to breathe with the condition which worsens over time.

Symptoms of COPD:

Symptoms include a productive cough, difficulty in breathing, wheezing, hyperinflated lungs, and a barrel chest. As the disease progresses patients may use accessory respiratory muscles to breathe and they may also appear cyanotic. 

Diagnosis:

Diagnosis is based on a physical exam, chest X-rays and Pulmonary  function tests. The Pulmonary  function tests show the airway limitation and give an indication of how severe the problem is.

Causes:

The most important cause of COPD is cigarette smoking over a long period of time.  The alpha-1 antitrypsin disorder, which is a genetic disease, is a cause among people who do not smoke. 

Risk factors and complications for COPD:

People who have the alpha-1 antitrypsin disorder are at increased risk of developing COPD. Cigarette smoking over many years and exposure to smoke through cooking or similar activities are also risk factors for COPD. Complications can occur in people with COPD if they become infected with bacteria such as Haemophilus influenzae. Repeated bacterial infection can increase the inflammation and progression of the COPD. Life expectancy with COPD varies from 8 to 14 years depending on the stage of the disease.

Prevention and treatment:

Not smoking cigarettes or stopping smoking, and avoiding exposure to smoke can help to prevent COPD. Treatment can include using bronchodilators and corticosteroids. Oxygen therapy may be needed in some cases, and eventually, a person may require a lung transplant.

 

What is Pulmonary  Fibrosis ?

Definition of Pulmonary  Fibrosis :

Pulmonary  Fibrosis  is the condition in which lung tissue becomes scarred such that breathing becomes difficult. 

Symptoms:

Symptoms include a nonproductive cough and difficulty breathing, at first, the difficulty in breathing occurs when exercising. Patients may feel very tired and have clubbing of their toes and fingers. Muscle aches may occur and patients may lose weight.

Diagnosis:

Diagnosis is based on a combination of a physical exam noting symptoms, hearing crackles in the lungs and the use of a high-resolution CT scan. Chest X-rays also show findings such as opacities and honeycombing, and the CT scan shows opaque regions as well.

Causes of Pulmonary  Fibrosis :

Often the exact cause of Pulmonary  Fibrosis  is not known. Genetics and environment may play a role in the development of the disease. Some environmental polluting agents such as dust may cause the disease, including metal dust such as silica. In some cases, medication can cause the condition. For instance, certain chemotherapy medicines such as bleomycin and methotrexate can trigger Pulmonary  Fibrosis .

Risk factors and complications:

Research has suggested that metal dust, such as silica and alumina, and wood dust are risk factors for developing Pulmonary  Fibrosis . Studies have also indicated that smoking cigarettes and certain viruses can also increase the risk of a person developing Pulmonary  Fibrosis . Viruses such as Epstein-Barr, Hepatitis C, and HIV are speculated as being possible risk factors for later development of Fibrosis  of the lungs. Some genetic mutations also appear to increase a person’s risk. The condition of Pulmonary  Fibrosis  leads to death within 4 to 5 years. 

Prevention and treatment for Pulmonary  Fibrosis :

A person should limit their exposure to harmful dust in the environment. This means that protective masks should be used as much as possible. Medication can be given to try to slow down the Fibrosis . Drugs such as pirfenidone and nintedanib are often used. Patients can be given oxygen to help lung function, and people younger than 65 may be able to get a lung transplant. 

 

Difference between COPD and Pulmonary  Fibrosis ?

  1. Definition

COPD is a chronic obstructive Pulmonary  disease where the airflow becomes restricted. Pulmonary  Fibrosis  is the condition in which there is scarring of the lungs.

  1. Symptoms

COPD has symptoms such as wheezing, difficulty breathing, productive coughing, hyperinflated lungs and having a barrel chest. In comparison, Pulmonary  Fibrosis  has symptoms of difficulty in breathing, nonproductive cough, fatigue, clubbing of fingers and toes, weight loss, and muscle aches.

  1. Diagnosis

The condition of COPD is diagnosed based on a physical exam and chest X-rays showing hyperinflated lungs.  The condition of Pulmonary  Fibrosis  is diagnosed by physical exam and X-rays and CT scans showing areas of opacity and honeycombing in the lungs.

  1. Causes

The causes of COPD are cigarette smoking and having the genetic condition of alpha-1 antitrypsin disorder. The cause of Pulmonary  Fibrosis  is often exposure to dust from heavy metals, but in some cases is unknown. Genetics and chemotherapy medicines can also be a cause of the Fibrosis .

  1. Risk factors

Risk factors for COPD include having the alpha-1 antitrypsin disorder and smoking cigarettes. Risk factors for Pulmonary  Fibrosis  include breathing in metal dust, cigarette smoking, genetic mutations, and some viruses.

  1. Life expectancy

The life expectancy of people with COPD is 8 to 14 years, while the life expectancy of people with Pulmonary  Fibrosis  is from 4 to 5 years.

  1. Treatment for 

COPD is treated with bronchodilators, corticosteroids, supplementary oxygen, and lung transplant. Pulmonary  Fibrosis  is treated with medications:  pirfenidone and nintedanib, supplementary oxygen, and lung transplant.

Summary of COPD Vs. Pulmonary  Fibrosis 

  • The COPD and Pulmonary  Fibrosis  are both conditions that can lead to death as they seriously affect breathing ability in people.
  • Smoking cigarettes is a risk factor for both conditions.
  • COPD can be diagnosed based on a chest X-ray as can Pulmonary  Fibrosis .
  • Patients with COPD or Pulmonary  Fibrosis  may require a lung transplant in order to survive.
