What is Bronchitis?
« on: November 09, 2008, 08:41:31 PM »
Bronchitis can be classified as either acute or chronic. Acute bronchitis can be defined as acute bacterial or viral infection of the larger airways in healthy patients with no history of recurrent disease.[2] It affects over 40 adults per 1000 each year and consists of transient inflammation of the major bronchi and trachea. [4] Most often it is caused by viral infection and hence antibiotic therapy is not indicated in immunocompetent individuals. [5][6] There are no effective therapies for viral bronchitis. [6][7] Treatment of acute bronchitis with antibiotics is common but controversial as their use has only moderate benefit weighted against potential side effects (nausea and vomiting), increased resistance, and cost of treatment in a self-limiting condition. [4][8] Beta2 agonists are sometimes used to relieve the cough associated with acute bronchitis. In a recent systematic review it was found there was no evidence to support their use. [6]

Acute Exacerbations of Chronic Bronchitis (AECB) are frequently due to non-infective causes along with viral ones. 50% of patients are colonised with Haemophilus influenzae, Streptococcus pneumoniae or Moraxella catarrhalis.[2] Antibiotics have only been shown to be effective if all three of the following symptoms are present:- increased dyspnoea, increased sputum volume and purulence. In these cases 500mg of Amoxycillin orally, 8 hourly for 5 days or 100mg doxycycline orally for 5 days should be used.
