Acute Exacerbation of Chronic Bronchitis (AECB) caused by susceptible bacteria

What is Acute Exacerbations of Chronic Bronchitis (AECB)?

Acute Exacerbations of Chronic Bronchitis (AECB) is an exacerbation or worsening of the symptoms of chronic bronchitis, a type of chronic obstructive pulmonary disease (COPD).It is generally associated with a bacterial (or, rarely, viral) infection.

What are the Causes of Acute Exacerbations of Chronic Bronchitis (AECB)?

AECB is usually caused by a bacterial infection of the airways. Common bacteria that cause AECB include Haemophilus influenzae, Streptococcus pneumoniae, and Moraxella catarrhalis. Viral infections, such as those that cause the common cold, can also lead to an AECB.

Symptoms of Acute Exacerbations of Chronic Bronchitis (AECB)

Symptoms of an AECB include worsened cough, increased shortness of breath, wheezing, and sputum production. A fever may also be present. Other symptoms include fatigue, chest discomfort or tightness, and headache.

Managing Acute Exacerbations of Chronic Bronchitis (AECB)

Treatment of AECB aims to manage both the bacterial infection and the underlying problem of chronic bronchitis itself. In severe cases, the patient may need to be hospitalized for aggressive treatment. Treatment may be in the form of oral or intravenous antibiotics, anti-inflammatory medications, bronchodilators, and oxygen therapy.

Patients may also be advised to avoid triggers of an exacerbation, such as air pollution and cigarette smoke. Other treatment recommendations may include quitting smoking, exercising regularly, and maintaining good nutrition.
