Pathophysiology of COPD

 The most consistent pathological finding is hypertrophy and increase in number of the mucus secreting goblet cells of the bronchial tree, evenly distributed throughout the lungs but mainly seen in the larger bronchi.
 In more advanced cases, bronchi themselves are inflamed ; there will be infiltration of the walls of the bronchi and bronchiole with acute and chronic inflammatory cells and lymphoid follicles.
 The epithelial layer may become ulcerated and when ulcers heal, squamous epithelium may replace the columnar cells – squamous metaplasia
 Inflammation is then followed by scarring and a remodeling process that thickens the walls and leads to widespread narrowing in the small airways.
 If the airway narrowing is combined with emphysema, then the resulting airflow is even more severe.


 The small airways are particularly affected in the initial stage of the disease, initially without the development of any significant breathlessness.
 The initial inflammation of the small airways are reversible ; there will be improvement if smoking stops early. In later stages, the inflammation continues even if smoking is stopped.


 Emphysema leads to expiratory airflow limitation and air trapping. The loss of lung elastics recoil increases total lung capacity while the loss of alveoli with emphysema results in decreased gas transfer.
 V/Q mismatch occurs because of damage and mucus plugging of smaller airways from chronic inflammation and partly because of the rapid closure of the smaller airways owing to loss of elastic recoil from emphysema.
 This leads to a fall in PO2 and an increase in the work of respiration.
 However, many patients will show low normal PCO2 values – pink puffers – seek to maintain their blood gases by increasing their respiratory effort.
 Other patients who fail to maintain their respiratory effort will have a high level of CO2.
 In the short term, the rise in CO2 level will stimulate the increase in respiration rate but in the long term, these patients become insensitive to CO2 and come to depend on hypoxemia to drive the ventilation.- adaptation of central chemoreceptors due to kidney compensation
 These patients appear less breathless, and because they run on low PO2 level, production of RBCs and retention of fluid will be stimulated and hence, polycythaemia.
 In consequence, they will become bloated, plethoric and cyanosed.
 Attempts to abolish hypoxemia may make the situation much worse by decreasing respiratory drive in patients who rely on hypoxia to drive their ventilation.
 In summary, 3 mechanisms are suggested for the limitation of airflow :
 Loss of elasticity and alveolar attachments of air airways due to emphysema.
 Inflammation and scarring – narrowing of airways
 Mucus secretion which blocks the airways
Pathophysiology of asthma
Airways of asthma patients are hypersensitive  type 1 hypersensitivity  bronchi spasm  inflammation
Parasympathetic of afferent nerve endings in the lining of the bronchus is stimulated and impulse travels to brain then efferent nerve endings releasing Ach and causing formation of inositol 1,4,5-triphosphate (IP3) in bronchial smooth muscles  shortening bronchoconstriction.
Bronchial inflammation
Allergens gets ingested by antigen-presenting cells and present the allergen to immune cells TH0 and gets ignored, but in asthma, TH0 transform into TH2.
Activates humoral immune system  antibodies against the inhaled allergen  Inflammation  wall of airway thicken, remodeling due to scaring of the airway, mucus producing cells grow larger and produce more and thicker.
The "hygiene hypothesis" postulates that an imbalance in the regulation of these TH cell types in early life leads to a long-term domination of the cells involved in allergic responses over those involved in fighting infection. The suggestion is that for a child being exposed to microbes early in life, taking fewer antibiotics, living in a large family, and growing up in the country stimulate the TH1 response and reduce the odds of developing asthma
Pathophysiology of Emphysema
 Panacinar (or panlobular) emphysema: The entire respiratory acinus, from respiratory bronchiole to alveoli, is expanded. Occurs more commonly in the lower lobes, especially basal segments, and anterior margins of the lungs.[2]
 Centroacinar (or centrilobular) emphysema: The respiratory bronchiole (proximal and cen-tral part of the acinus) is expanded. The distal acinus or alveoli are unchanged. Occurs more commonly in the upper lobes.[2]

Toxicants are breathed into the lungs, it is trapped in the alveoli  Localized inflammation
One of the inflammatory response, leucocyte elactase cause alveolar septum to disintegrate.(Septal rupture)  Deformed alveoli  Reduced surface area  Decrease gas exchange
Also decreased elastin, loss of support  alveoli tend to collapse  limiting air flow
With reduced surface area  Thoracic cage expansion (barrel chest), and diaphragm contraction (flat-tening)  CO2 exhalation impaired
As it continues to break down  hyperventilation unable to compensate for shrinking surface area  insufficient O2  vasoconstriction (hypoxic pulmonary vasoconstriction)  pulmonary hypertension  increased strain on right side of heart, right heart hypertrophy  jugular venous distension  blood start backing up (liver)
Alpha 1-antitrypsin (A1AT) breaks down elastase
Thus, increased risk in patients with alpha 1-antitrypsin deficiency for emphysema

However, more recent studies have brought into light the possibility that one of the many other numer-ous proteases, especially matrix metalloproteases might be equally or more relevant than neutrophil elastase in the development of non-hereditary emphysema.

Signs & Symptoms and Causes of Chronic bronchitis

Definition- Bronchitis

Bronchitis is a term that describes inflammation of the bronchial tubes (bronchi and the smaller branches termed bronchioles) that results in excessive secretions of mucus into the tubes, leading to tissue swelling that can narrow or close off bronchial tubes. Bronchial tubes extend from the trachea and terminate at the alveoli in the lungs; the bronchial system resembles an inverted tree and is sometimes termed the "bronchial tree." A few authors include the trachea and upper airway in the definition. There are two major types of bronchitis, acute and chronic.

Definition-chronic bronchitis

Chronic bronchitis is defined as a cough that occurs every day with sputum production that lasts for at least three months, two years in a row. This definition was developed to help select uniform patients for research purposes i.e. to study medication therapies for treatment of chronic bronchitis. Many of the bronchi develop chronic inflammation with swelling and excess mucus production in chronic bronchitis; the inflammation, swelling, and mucus frequently and significantly inhibit the airflow to and from the lung alveoli by narrowing and partially obstructing the bronchi and bronchioles. Many cells that line the airway lose the function of their cilia (hair-like appendages that are capable of beating rapidly), and eventually the ciliated cells are lost. Cilia perform the function of moving particles and fluid (usually mucus) over the epithelial surface in such structures as the trachea, bronchial tubes, and nasal cavities to keep these hollow structures clear of particles and fluids. Mucus-producing cells increase due to irritation. These cells produce a viscous fluid that facilitates cleansing of the airway. If the mucus becomes thick (less fluid or viscous, it may contribute to airway blockage.
With long standing inflammation, as can be seen in chronic bronchitis, scarring inside the bronchial tree may develop. These scarred areas do not clear particles and secretions very well, and can result in a fixed, non reversible narrowing of the airway and the condition, chronic obstructive pulmonary disease (COPD). Chronic coughing develops as the body attempts to open and clear the bronchial airways of particles and mucus or as an overreaction to ongoing inflammation. Chronic bronchitis can be a progressive disease; symptoms (listed below) increase over time.
COPD also includes the entities of emphysema, chronic bronchitis, and chronic asthma. These conditions are not always separable and patients often have components of each. In the case of chronic bronchitis, the fixed airway obstruction, airway inflammation and retained secretions can result in a mismatch of blood flow and airflow in the lungs. This can impair oxygenation of the blood as well as removal of the waste product, carbon dioxide.

Although people of any age can develop chronic bronchitis, the majority of people diagnosed with the disease are 45 years of age or older.

Causes

There can be many causes of chronic bronchitis, but the main cause is cigarette smoke. Statistics from the US Centers for Disease Control and Prevention (CDC) suggest that about 49% of smokers develop chronic bronchitis and 24% develop emphysema/COPD. Some researchers suggest that about 90% of cases of chronic bronchitis are directly or indirectly caused by exposure to tobacco smoke.

Many other inhaled irritants (for example, smog, industrial pollutants, and solvents) can also result in chronic bronchitis.

Viral and bacterial infections that result in acute bronchitis may lead to chronic bronchitis if people have repeated bouts with infectious agents.

Also, underlying disease processes (for example, asthma, cystic fibrosis, immunodeficiency, congestive heart failure, familial genetic predisposition to bronchitis, and congenital or acquired dilation of the bronchioles, known as bronchiectasis) may cause chronic bronchitis to develop, but these are infrequent causes as compared to cigarette smoking.


Signs & Symptoms

Cough and sputum production are the most common symptoms; they usually last for at least three months and occur daily. The intensity of coughing and the amount and frequency of sputum production vary from patient to patient. Sputum may be clear, yellowish, greenish, or occasionally, blood-tinged. Since cigarette smoke is the most common cause for chronic bronchitis, it should not be surprising that the most common presentation is so called smoker's cough. This is characterized by a cough that tends to be worse upon arising and is often productive of discolored mucus in the early part of the day. As the day progresses, less mucus is produced.

Dyspnea (shortness of breath) gradually increases with the severity of the disease. Mucus plugs up and makes it hard for them to bresthe. Usually, people with chronic bronchitis get short of breath with activity and begin coughing; dyspnea at rest usually signals that COPD or emphysema has developed.

Wheezing (a coarse whistling sound produced when airways are partially obstructed) often occurs.

In addition, symptoms of fatigue, sore throat, muscle aches, nasal congestion, and headaches can accompany the major symptoms. Severe coughing may cause chest pain; cyanosis (bluish/grayish skin coloration) may develop in people with advanced COPD. Fever may indicate a secondary viral or bacterial lung infection. When symptoms worsen or become more frequent, this is often referred to as an exacerbation of chronic bronchitis. These exacerbations often require antibiotics, and may need steroid medication and an increase in respiratory inhaled medications.

Diagnosis

Using a combination of a person's medical history, physical exam, and diagnostic tests. A history of a daily productive (sputum production) cough that lasts at least three months, especially if has occurred two years in a row, fits the criteria for a clinical diagnosis of chronic bronchitis. The physical examination often allows caregivers to hear wheezes, a sign of airflow obstruction.

A chest X-ray is often performed to help rule out other lung problems (for example, pneumonia, bronchial obstructions). Additional tests such as a complete blood count(CBC), arterial blood gas measurements, CT scan of the chest, and pulmonary function tests are often done to characterize the structure and function of the lungs and to exclude other conditions.

Financial and social implications of asthma

The stress of living with a chronic disease reveals itself in many ways among the various family members.

Someone with asthma may be more likely to

• get involved in fights
• be less cooperative
• be stubborn
• depressed
• anxious
• Withdrawn
• Be timid

Parents of kids with asthma are more likely to suffer from

• Fatigue
• Headaches
• Insomnia
• Depression and
• Appetite loss

Siblings of kids with asthma may

• Feel guilty, thinking that somehow they have caused the illness.
• They also may be jealous or angry because of the additional attention their sibling receives
• or they may be afraid that they may get the asthma themselves
• Some may also feel embarrassed by the symptoms that their sibling displays
