COPD Flashcards
Chronic Obstructive Pulmonary Disease (COPD)
-PERSISTANT respritory symptoms
-airflow limitation
-PROGRESSIVE
-exacerbations
-comorbities
true or false: deaths resulting from COPD are higher in women than in men
true.
COPD prevalence
-3rd leading cause of death
-affects females more than males
-affects American indians/alaskan native descendants more
COPD pathophysiology
-emphesema and chronic bronchitis
what is required for COPD diagnosis?
spirometry test
-FEV1/FVC <70% post bronchodialator
COPD symptoms
-dyspnea
-chronic cough
-sputum production
-wheezing, chest tightnes
-lower respritory tract infections
COPD risk factors
-exposure to particles
-Socioeconomi status
-age and sex
-genes
-asthma, chronic bronchitis
-childhood lung abnormalities
Emphysema
-in aveoli
-destruction of lung parenchyma
-decreased lung elasticity
-causes SOB, wheezing
chronic bronchitis
-inflammation in the airways(bronchi)
-mucus overproduction
COPD stimulus
-cigarette smoke
-over pollutants
how often to get spirometry performed?
1 x/year
Does COPD have reversibility?
No
COPD spirometry values
post bronchodilator FEV1/FVC <0/7
Gold 1: mild
FEV1 > 80%
Gold 2: moderate
50<FEV1< 80%
Gold 3: severe
3-50% FEV1
COPD stable, initial treatments
-SABA/LABA
-SAMA/LAMA
-or combo products
Lonhala Magnair
-nebulized Glycopyrrolate
-BID 2-3 min each
Yupelri
-Revefenacin Neb soln
-3 ml
-once daily for 10 min
LAMA side effects
-dry mouth
-bitter taste
-nasopharyngitis
-urinary retention
-worsening of narrow angle glaucoma
LAMA Use in therapy
-NOT rescue meds
-do not treat acute COPD symptoms
Yupelri drug interactions
-OATP1B1
OATP1B3
-rifampin
-cyclosporine
Brovana
-aformoterol neb soln
Perforomost
formoterol neb soln
LABA side effects
-sinus tachycardia
-cardiac rhythm disturbances
LABAs place in therapy
-monotherapy for patients with mild or moderate COPD
-not rescue medications
Considerations for LABAs
-other QTc prolong medications
-MAOI
LABA/LAMA combo products
Anoro ellipta
-umeclidium and vilanterol
-interacts with ketoconazole
LABA/LAMA place in therapy
-step up therapy if patient is still symptomatic
SABA
-threat acute symptoms
ICS
-should not be monotherapy
-should be used in tripple therapy
-may even reduce mortality
risk of ICS in COPD
-higher incidence of pneumonia
-oral candiasis
-hoarse voice
Eosinophils
-key factor in deciding if patient recieves ICS
COPD and asthma
-treat like patients with asthma
-always use ICS
ICS: Factors strongly favor use
-hospitilization for COPD
-> 2 mod exacerbations last year
-eosinophils>300
ICS: Factors favor use
-1 mod exacerbation
-eosinophil 100-300
ICS: Factors againist use
-repeated pneumonia events
-eosinophil <100
-hx of mycobacterial infection
COPD Assessment Test (CAT)
-Higher CAT score is worse symptoms
->30 very high impact
Initial: Cat <10 and 0-1 exacebations
Bronchodialator
Initial: Cat >10 and 0-1 exacebations
LABA + LAMA
Initial: anyone who has had more than 2 exacerbations or 1 leading to hospitalization
-LABA+LAMA
-triple therapy if eosinophils>300
Roflumilast
-decrease risk of COPD exacebations in SEVERE AND VERY SEVERE COPD
-FEV1<50%
-chronic broncitis
-history of exacerbations
Roflumilast side effects
-psychiatric events
-weight loss( 2 kg)
-GI upset, diarrhea
Roflumilast drug interactions
-strong CYP450 inducers
-carbamazapine
=phenytoi
-phenobarbital
-rifampin
Roflumilast contraindications
-mod to severe liver impairment
Azithromycin
-for severe COPD AND not a current smoker
Azithromycin side effects
-prolong QTc
-impaired hearing
-increase bacterial resistance
Dupilumab
-studied in people eosinophils>300
Ensifentrine
-nebulizer
-dual PDE3 and PDE4 inhibitor
-bonchodialator
-anti inflammatory
step down from ICS therapy
-cold turkey
-worse withdrawal with patients that have higher eosinophils
