Q

asthma definition

A
  • Inflammatory d/o of airways
  • Reversible airflow obstruction
  • Hyper-responsiveness
  • Often viewed as atopic, allergic d/o with altered T cell function
  • Best to view it as BOTH inflammatory AND smooth muscle d/o
    • Variable severity and reversibility
    • Tx should addres BOTH of these
    • FH important!

Q

Dx of asthma: important points

A
  • Children with asthma are often mislabeled (bronchitis, bronchiolitis, croup, pneumonia) and may not get adequate therapy
    • DX NOT NEEDED TO CONSIDER AND BEGIN TREATING ASTHMA SX!!
    • Viral URI are MC precipitant of wheezing and cough in kids- do NOT preclude the dx of asthma= it is possible to have asthma and have it triggered by a viral illness!
  • Recurrent episodes of cough and wheeze are almost always d/t asthma in both adults and kids
  • Cough can be sole sx

Q

Gain control

A
  • Preferred approach is to start therapy with more intensive program
    • Suppresses airway inflammation and gain prompt control of reversible obstruction
    • Ex: burst therapy steroids
  • To do this, you need to define the severity of asthma
  • Intervene with optimal medications
  • Normalize activities, lung function and lifestyles
  • Then try to “step down” tx to optimal levels

33
Q

Acute Tx or “Rescue” Therapies

A
  • Inhaled short acting β2 agonists (SABA) (Albuterol, Xopenex®)
  • Systemic (injected) β2 agonists (epinephrine, terbutaline)
  • Anticholinergics (Ipratropium bromide – Atrovent)
  • Systemic steroids (Prednisone; PO preferred)
    • 100% bioavailable; drug goes everywhere (not just lungs!)
  • Oxygen, hospitalization, ventilation
34
Q

Chronic “Controller” Therapies

A
  • Inhaled corticosteroids (Flovent®, Pumicort©, Qvar®, Asthmanex®)
    • Only about 2% is absorbed systemically (most goes directly to lungs)
  • Long-acting bronchodilators (LABA) (Serevent®, Foradil®)
    • NEVER use as monotherapy!
  • Mast cell stabilizers (Intal®): not used often
  • Leukotriene modifiers (Singulair®): good add-on therapy
  • Combination therapies (Advair®, Symbicort®, Dulera®)
35
Q

Asthma Medications

A
  • Long-term controller asthma meds are taken daily to achieve and maintain control of persistent asthma sx
    • Most effective long-term maintenance meds reduce inflammation!
      • Inhaled steroids are best for persistent asthmatics
      • ICS = First-line maintenance therapy for ALL persistent asthma, even mild
    • Other classes of controller drugs, such as the LTM’s can be used, but they have limitations!
36
Q

Inhaled Corticosteroids (ICS)

A
  • ICS can decrease airway inflammation and bronchoconstriction of smooth muscle in mild to moderate asthmatics.
  • Earlier tx with ICS appears to prevent pts from developing more prominent chronic lung changes and airway obstruction
    • Long term use (> 2 yrs) significantly improves lung fxn
    • Safe to use
37
Q

Daily use of ICS can

A
  • Diminish asthma sx; improvement will continue gradually
  • decreases occurrence of severe exacerbations
  • decreases use of quick-relief meds
  • Improved lung fxn (PEF, FEV1, & airway hyperresponsiveness)
38
Q

Effects of ICS on Inflammation

A
  • Inhibits inflammatory mediator cells (decreases airway edema)
  • Can reverse effects of airway remodeling
39
Q

Long-Acting b2-Agonists (LABA)

A
  • Safe and effective, easy to use, quick onset of action, well-tolerated
  • Enhance benefits of ICS & more effective than ↑ ICS
  • Treats nocturnal cough & exercise-induced bronchoconstriction for up to 12-14 hrs after use
  • Enhance adherence and improve lung fxn
  • NOT TO BE USED AS MONOTHERAPY!
40
Q

Combination Therapies (ICS + LABA)

A
  • Serevent® and Flovent® are available together in a DPI (Diskus® ) as Advair®(100/50, 250/50, 500/50)
  • Clinical efficacy of a LABA & ICS is due to complementary actions of these two classes of drugs
    • Treats BOTH inflammation and bronchoconstriction in a single device = IDEAL

Leukotriene Modifiers (LTM)

  • Class of agents used in asthma therpay BUT limited long-term data exists
    • Best used as add-on therapy, esp. for stuffiness and persistent cough
    • Easy to dose, lack of perceived “steroid side effects”

Play a role in initial asthma tx, however, only a fraction of people treated with these agents appear to respond to therapy and they tend to have milder and more intermittent disease

41
Q

asthma medical therapies

A
  • Overall, short-acting bronchodilators account for over 50% of all asthma Rx among children and adults.
    • Despite that asthma is now recognized as a chronic inflammatory disorder
  • In Georgia, less than half of all asthmatics who need daily “controller” meds actually have them prescribed.
42
Q

measuring effectiveness of asthma tx

A
  • Improvement in lung fxn tests or PFT’s (spirometry: FEV1 > 6% or FEF25-75 > 35%)
  • Improved AM/PM Peak Expiratory Flow
    • Using Peak Flow Meters (measure speed & amt of air expelled in single puff)
  • decrease use of “rescue” drugs (200 puffs per canister)
    • Shouldn’t be using more than 4 canisters annually!
  • decrease daytime and exercise-related resp. sx
  • decrease nocturnal awakenings/cough
  • Improved “quality of life”
43
Q

Metered Dose Inhalers (MDI)

A
  • MDI’s are mainstay for most asthma controller meds prescribed in US
    • Small, portable, efficient, quick, & inexpensive to use (and lose!)
  • When used with a spacer device, MDI’s deposit particles in small airways as effectively as nebs
    • Effectively used at any age
    • Technique is CRITICAL! Require SLOW INSPIRATORY flow rates
44
Q

Typical MDIs

A
  • Asthma spacers
  • Dry Powder Inhalers (DPI’s)
  • Diskus
45
Q

Dry Powder Inhalers (DPI’s)

A
  • Improved ease of use
  • Impact of impending CFC phase-out
  • decrease volume of inhaled powder
  • Dose counters/indicators
  • ↑ dose capacity in devices
  • No dose to dose variation
46
Q

Diskus®

A
  • Open: Expose level underneath device
  • Click: Push lever away until you hear or feel a click
  • Inhale: Exhale, then bring device to lips and breathe in steadily & deeply thru inhaler. Airflow thru device ensures that dose is inhaled
  • Close Diskus
47
Q

73
Q

PFT for hyperinflative COPD

A
  • increase in RV, TLC
74
Q

PFT for abnormal gas exchange COPD

A
  • decrease in DLCO
75
Q

COPD ABG

A
  • decrease PaO2, increase in PaCO2
76
Q

COPD clinical pearls

A
  • Methylxanthines
    • Theophylline
      • narrow therapeutic window
      • Cardiac sequelae if toxicities
      • Sometimes works, sometimes doesn’t
  • PO Albuterol is not safe from a cardiac standpoint (many COPD patients have concomitant cardiac disease)
  • Watch out for pneumothorax due to bullae; do a CXR with unexplained worsening dyspnea
  • In a young patient (age 40 or less) with COPD and a minimal or no smoking history, check an alpha-1 antitrypsin level…looking for a low level, indicating deficiency.
    • This is a genetic cause of COPD
  • Much higher incidence of COPD in HIV patients
  • Discuss code status with all COPD patients…IN THE OFFICE
77
Q

How to spot an acute exacerbation

A
  • From patient’s baseline:
    • Change in sputum color
    • Increase in shortness of breath
    • Increase in amount of sputum
  • Also look for signs of infection:
    • Fever, chills, hemoptysis, crackles/rales on lung exam
78
Q

COPD Exacerbation

A
  • CXR to rule out pneumonia as a cause for the exacerbation
  • Check oxygen saturation!
  • Decide whether or not to treat as an outpatient:
    • PO steroids (prednisone)/bronchodilators
    • PO Antibiotics
    • Close follow up
79
Q

COPD exacerbation Tx

A
  • Hospitalized (hypoxemic, very dyspneic, fever, weakness)
    • IV steroids, usually methylprednisolone, starting at 60mg IV Q6 hours, and taper…try not to dose less than Q8 hours for duration due to drug ½ life (transition to prednisone for discharge)
    • Scheduled nebs; if on tiotropium (anticholinergic) do NOT use ipratropium
  • When giving oxygen give only enough to get PaO2 above 60mmHg; this minimizes the danger of respiratory acidosis due to CO2 retention.
  • Levalbuterol (q6 hours) or albuterol (q4 hours) nebs
  • Mucolytic (guaifenesin) prn
  • Sputum cultures, usually give antibiotics, covering for S. pneumo, H. flu, M. cat.
    • Quinolones, cephalosporins, penicillins, macrolides
80
Q

COPD smoking cessation options

A
  • Nicotine replacement
  • Behavioral modification
  • Bupropion (Zyban, Wellbutrin)
  • Varenicline (Chantix)
81
Q

Smoking Cessation: other

A
  • Patients need you to initiate the conversation…EVERY VISIT
  • Medicare now reimburses for smoking cessation counseling
  • If you don’t attempt it, you are not doing your job
  • Bring them back for a smoking cessation visit
82
Q

COPDer

A
  • C: Corticosteroids (inhaled)
    • 20% decrease in Acute exacerbations, but can increase risk of pneumonia
  • O: Oxygen
  • P: Prevention (Flu/Pneumovax, tob cessation)
  • D: Dilators (Anticholinergic, SABA, LABA)
  • E: Experimental (LVRS = lung volume reduction surgery)
  • R: Rehabilitation
