I- Definition :

C’is an acute inflammation of the bronchi or terminal bronchioles, d’most often viral or viro-bacterial origin, d’benign course

The initial stage often associated with destruction epithelial cell migration from the peri-lesional, vasodilatation and hypersecretion of mucus are responsible for the catarrhal stage

II- Clinique :

After the catarrhal stage VAS occur signs of bronchitis :

dry phase (initial) :

• Cough painful dry hacking, nonproductive promoted by changes in ambient temperature
• Retro sternal pain was like burning
• dyspnea’effort
• Temperature increase (38-38,5) oscillating, control of viremia
• TIME (asthenia, cephalalgia, myalgie)
• A l’auscultation : groans sounding as they may be replaced by wheezing low frequency (differential dgc with l’bronchial asthma)
• duration 4-5 J

wet phase :

• Duration 3-4 J
• Cough or dry or painful
• General signs s’amendment
• Dyspnea disappears
• The cough becomes oily, bringing a sero-mucous expectoration which can become muco- purulent in case of bacterial superinfection
• Hemoptysis small abundance can sometimes appear and impose an endoscopy if the ground permits

III- Evolution :

• self-limiting, without sequelae
• The cough may persist for several weeks or even months with the’appearance’post-viral bronchial hyperreactivity
• Especially in a smoking, it can lead to chronic bronchitis table

IV- Etiology :

viral :

• Myxovirus
• Paramyxovirus
• cytomegalovirus
• adenovirus

bacterial :

• Hemophilus influenzae
• Streptococcus pneumoniae
• Chlamydia pneumoniae
• Mycoplasma pneumoniae
• Bordetella pertuisis

V- clinical form :

Some are more worrying than d’other :
– Thrust d’exacerbation d’chronic bronchitis (table d’IRA)
– Exacerbation des DDB : risk of’OAP at l’insufficient left ventricular
– chest irradiation for neighborhood Cancer (his, thyroid, bronchi)

WE- Additional tests :

– FNS : normal, hyperleucocytose (bacterial), leucopénie (viral)
– ECB from l’expectoration especially in the’insufficient breathing
– Pulmonary radiography : aspect of dirty lung :

• linear image rail
• Image areal : thickening of airway walls
• Opacities micronodular lesions predominant bases

Who translate l’inflammation of the peribronchial interstitial tissue

– Reviews on private land : Rx you sine, EFR, gasometry, fibroscopie, immunological assessment, sweat test, TDM)

VII- Treatment :

Symptomatic treatment : TRT mere acute bronchitis
– Antipyretic
– antitussive for 2-3 J then quickly replaced by mucolytics and muco-modifiers (anti-inflammatory action and sedative)

Cure : (complicated forms)
– Penicillin
– atypical germ : tetracycline, macrolide
– On land weakened : energetic ATBpie (combination therapy)
– Treat the’exacerbation and terrain

Preventive treatment :
– Vaccine every flu every year (autumns)
– Pneumococcal Vaccine every 5 years (spring)
