Treatment of Asthma

INTRODUCTION
 Asthma is a chronic disease principally characterized by episodic wheeze, cough,
and breathlessness resulting from airway hyper responsiveness and inflammation.
 It is one of the most common chronic lung diseases in the United States, affecting
approximately 8% of adults, or about 20 million individuals.
 Consequently, asthma is frequently encountered in the primary care setting.
 In the vast majority of cases, asthma is successfully managed by the generalist, and
most individuals with asthma are expected to achieve good control.
SIGNIFICANCE AND PREVALENCE
 Asthma is significantly more prevalent in women (10.4%) than in men (6.2%).
 Despite a wide array of treatment options, almost half of adults with asthma report
having one or more attacks in the previous year, highlighting the importance of
symptom management and disease control.
 Asthma is classically thought of as a disease that begins in youth.
 Although it is true that asthma is most commonly first diagnosed in childhood, it
can become clinically apparent at any age.
Pharmacologic Therapy
CONTROLLER MEDICATIONS
 The general goal of controller therapy is to intervene in the inflammatory process
and to prevent the development of irreversible airway remodeling.
 ICS form the backbone of controller therapy.
 Common side effects include oral thrush.
 LABA or leukotriene modifiers may be added to ICS.
 Long-acting muscarinic antagonists, which are commonly used in COPD, do not
appear to be superior to LABA as add-on therapy in asthma and are typically
reserved for severe disease.
RESCUE MEDICATIONS
 A rescue inhaler in the form of albuterol should be offered to patients. This short
acting medication provides immediate bronchodilation in patients with acute
symptoms.
 Spacers and neubilizers can also be used.
 Patients with intermittent asthma may achieve control with a short-acting beta-
agonist alone but with persistent asthma necessitate addition of ICS.
SELF MANAGEMENT:
The foundation of asthma self-management is an asthma
action plan.
Patients are provided with a peak flow meter.
Patients then check their peak flows daily or when
experiencing worsened symptoms, and depending on the
value are classified as in:
 Green zone
 Yellow zone
 Red zone
Other Treatment Options in Severe Asthma
 The allergic inflammatory pathway is a common target.
 Omalizumab is an antibody against serum IgE.
 Mepolizumab, reslizumab, and benralizumab are antibodies targeting the
interleukin-5 pathway.
 For patients with difficult-to control asthma should use systemic corticosteroids,
and rescue inhaler.
ACUTE OUTPATIENT EXACERBATIONS OF ASTHMA
 For the outpatient with acute worsening of asthma symptoms, a focused history
and physical examination will readily guide management.
 Most acute exacerbations are precipitated by viral respiratory infections, in
particular, rhinovirus, evaluated on examination.
 Hypoxemia, use of accessory muscles, inspiratory and expiratory wheezing, and
absence of wheezing associated with respiratory discomfort are worrisome
symptoms..
 Radiographic abnormalities are rare in an uncomplicated exacerbation, and chest
imaging is not routinely performed.
Indications For specialist Referral
 Alternative pulmonary diagnosis suspected
 Asthma diagnosis suspected, but confirmation elusive
 Possible occupational asthma
 Persistently uncontrolled disease
 More than 1 exacerbation in past year
 History of life-threatening exacerbation
 Difficulty with medication selection
 Difficulty managing asthma due to comorbidities
 Severe disease requiring specialized therapy
