What is the plan for a patient who requires an onsite provider follow-up visit regarding their 4/12/25 visit, lab results, chest X-ray (CXR), pulmonary function test (PFT) results, and elevated Immunoglobulin E (IgE) level to assess for asthma and potential continued inhaler use?

From the Guidelines

I strongly recommend scheduling the patient for an onsite follow-up visit with their provider to review lab results, chest X-ray, and pulmonary function test (PFT) results from the April 12,2025 visit, as this will enable the provider to assess the patient's asthma control and determine the best course of treatment, taking into account the elevated IgE level of 34.8, which suggests possible allergic inflammation 1. This appointment should be scheduled for one month after the initial visit, around May 12,2025. During this follow-up, the provider will assess the patient for asthma, determine if continued inhaler therapy is necessary, and discuss the elevated IgE level of 34.8. The elevated IgE suggests possible allergic inflammation, which may be contributing to respiratory symptoms. This is particularly relevant to the asthma assessment, as allergic asthma often presents with elevated IgE levels, and according to the Expert Panel Report 3, anti-IgE therapy with omalizumab can be considered for patients with IgE-mediated allergic asthma 1. The provider will likely use the combined information from the patient's symptoms, physical examination, PFT results, and lab values to determine the appropriate treatment plan, which may include continuing, adjusting, or discontinuing inhaler therapy, and may also consider adding anti-IgE therapy if the patient's asthma is not well-controlled with current treatment 1. Some key points to consider during the follow-up visit include:

• Assessing the patient's asthma control using multiple measures, such as symptoms, use of short-acting beta-agonists, limitations to normal activities, pulmonary function, and exacerbations 1
• Evaluating the patient's response to current treatment and adjusting the treatment plan as needed, which may include stepping up or stepping down therapy 1
• Discussing the patient's elevated IgE level and its potential implications for their asthma treatment, including the possibility of anti-IgE therapy 1 The patient should bring any current inhalers to the appointment and be prepared to discuss how their symptoms have changed since the previous visit. By following these steps, the provider can ensure that the patient receives the most effective treatment for their asthma, taking into account their individual needs and circumstances.

From the Research

Asthma Management and Treatment

• Asthma is a chronic inflammatory disease of the airways that affects approximately 100 million people worldwide 2.
• The use of leukotriene modifiers, such as montelukast, zafirlukast, and zileuton, has been established as an effective treatment for asthma, improving pulmonary function, reducing symptoms, and decreasing the need for rescue medications 2.
• Inhaled corticosteroids (ICS) are also a common treatment for asthma, and the combination of ICS and leukotriene modifiers may be beneficial for patients with more severe asthma 3, 4.

Leukotriene Modifiers and Asthma Control

• Leukotriene modifiers have been shown to be effective in improving asthma control, reducing symptoms, and decreasing the need for rescue medications 2, 4.
• The addition of a leukotriene modifier to treatment with low-dose inhaled corticosteroids is equivalent to treatment with high-dose inhaled corticosteroids in patients with newly diagnosed mild-to-moderate asthma 3.
• Leukotriene modifiers may also have a potential anti-remodelling effect, which could be important for preventing or reversing airway structural changes in patients with asthma 4.

Elevated IgE Levels and Asthma

• Elevated IgE levels, such as the patient's IgE level of 34.8, may be associated with an increased risk of asthma exacerbations 5.
• The FCER2 gene, which encodes for a low-affinity IgE receptor (CD23), has been associated with poor response to inhaled corticosteroids in patients with asthma 5.
• Further research is needed to fully understand the relationship between IgE levels and asthma control, as well as the potential benefits of targeting IgE in asthma treatment 5.

Follow-up and Monitoring

• Regular follow-up and monitoring of asthma symptoms, pulmonary function, and IgE levels are important for optimizing asthma control and adjusting treatment as needed 2, 3, 4.
• The use of leukotriene modifiers and inhaled corticosteroids, as well as other treatments, should be individualized based on the patient's specific needs and response to treatment 2, 4.
