1. Etiology, pathogenesis of COPD 2. Diagnostic criteria 3. Principles of treatment 4. Step-by-step treatment
COPD and Bronchial Asthma are the most common diseases of lungs 4-10 % of adult people are ill with COPD In Europe 7,4 % of people have COPD Mortality of such patients is 10 %
According GOLD 2006 COPD – this is disease which is characterized by combination of clinical signs of chronic obstructive bronchitis (inflammation and narrowing of bronchi) and emphysema (changes of lung tissue structure).
Permanent hyperactivity of parasympathetic nervous system with hyperproduction of acetylcholine, bronchial spasm and hypersecretion of mucus Insufficiency of adrenal receptors in bronchial walls as the result of deep morphological changes with bronchial hypersecretion, bronchial spasm and cough Bronchial hyperreactivity which is characterized by immune inflammation of bronchioles walls All that lead to: 1) narrowing of bronchioles; 2) development of emphysema
1.Hypersecretion of mucus 2.Dysfunction of ciliary epithelium 3.Decreasing of air flow in bronchi 4.Hyperpneumatization of lungs 5.Disturbances of gases-exchange 6.Pulmonary hypertension 7.cor pulmonale
Severe smoking Occupational diseases Family anamnesis
Chronic cough is the earliest sign of COPD and arise earlier then dyspnea Sputum – as a rool in small amount, after cough Dyspnea – persistent, progressive, becomes worse during physical activity and in severe cases – even if patient is calm
Central cyanosis, emphysematous chest, additional breathing muscles are necessary for breathing Increasing of breathing rate, decreasing of its deepness, prolongation of expiration Percussion: decreasing of heart dullness Auscultation: wheezing, dry rales, heart tones are dull
Investigation of external breathing (spyrometry); Bronchodilatation test; Cytology of sputum; Blood analysis; X-ray; ECG; Blood gases;
FVC – max air volume which is expired during forced expiration after max inspiration; FEV1 (<80 %) FEV1/FVC (<70 %) Peak flow (of expiration)
Lungs are enlarged Dyaphragm is located lower than normally Narrow heart shadow Sometimes – emphysematous bullas
Is necessary to find bronchial reversibility Spyrometry has to be provided before and 15 min after inhalation of 400 mkg of Salbutamol (or min – 80 mkg of Ipratropium) Increasing of FEV1 more than 15 % tells us about reversibility
Stage and severity Signs І, mild - FEV І < 80%, FEV1/FVC < 70% - As a rule chronic cough with sputum II, moderate - 50%< FEV І < 80% - FEV1/FVC < 70% - Symptoms are more significant, presence of dyspnea during physical activity and exacerbation III, severe 30%< FEVІ < 50% FEV1/FVC < 70% - Symptoms cause worsening of life quality IV, very severe- FEVІ < 30% FEV1/FVC < 70% and CRF
Increasing of intensivity of treatment in correlation with COPD severity; Permanent basis therapy; Individual sensitivity of patients to different medicines leads to necessarity of permanent control; Inhaled medicines are useful.
Short action – (Ipratropium bromid, Berodual Н) has more slowly beginning but longer action than β2-agonists Prolonged action – (Thyotropium bromid, Spiriva ) is active for 24 hours
agonists of short action (Salbutamol, Fenoterol) – fast beginning of action, but duration – 4-6 hours 2-agonists of prolonged action (Salmeterol, Formoterol ) are active for 12 hours.
Theophyllines of prolonged action are useful – Teopec, Teotard.
Are useful for permanent basis therapy for patients with COPD III-IV st. Inhaled GCS are used. Prednisone may be used only during exacerbation and is not recommended for basis therapy
Inhaled GCS (Beclomethasone, Budesonid, Fluticasone). Seretid (GCS+Salmeterol) is used in patients with III-IV st. of COPD and oftern exacerbations in anamnesis.
