Seasonal Allergies

A 51-year-old man with a 20-year history of asthma and seasonal allergies presented with low-grade fever, progressive dyspnea on exertion, and wheezing that had persisted for 2 weeks. Four days earlier, he had been seen by his primary care physician and had started levofloxacin therapy. However, his respiratory symptoms had worsened, warranting hospitalization. He also reported pain in the abdomen and left flank and pain and swelling in the right metacarpophalangeal and right shoulder joints.

This 41-year-old woman rushed to the emergency department with a swollen, blistered tongue and difficultly in swallowing and speaking. Twenty minutes earlier she had eaten fish (for the first time in her life).

Most of the symptoms of allergic rhinitis, including nasal obstruction, rhinorrhea, sneezing, and nasal itching, respond to intranasal corticosteroids administered once or twice daily. However, many patients also need to take an antihistamine for adequate control of symptoms. While an antihistamine/decongestant combination can provide symptomatic relief, it fails to address the inflammatory component of allergic rhinitis. Thus, combining an intranasal corticosteroid or oral leukotriene modifier with an antihistamine might be a more effective strategy. Factors that can facilitate treatment adherence include minimizing the number of daily doses, allowing patients to select their own dosing schedules, and providing written instructions. Specific immunotherapy can be beneficial in select patients whose allergic rhinitis symptoms are not sufficiently controlled by pharmacotherapy. (J Respir Dis. 2005;26(5):188-194)

Abstract: For some patients with allergic rhinitis, symptoms can be reduced substantially by the use of allergen avoidance measures. However, many patients require pharmacotherapy, including antihistamines, decongestants, and intranasal corticosteroids, to adequately control their symptoms. The oral antihistamines are effective in reducing rhinorrhea, itching, and sneezing but are not effective against nasal congestion. Intranasal azelastine has been shown to be beneficial in patients with moderate to severe symptoms that are not sufficiently controlled by an oral antihistamine. Additional therapies include intranasal ipratropium, which specifically targets rhinorrhea, and cromolyn, which can reduce many of the symptoms of allergic rhinitis and can be used prophylactically.

ABSTRACT: Many patients with presumed mild intermittent asthma have unrecognized persistent symptoms; these can be elicited with specific questioning about coughing, wheezing, shortness of breath, chest tightness, nighttime awakenings, and exercise intolerance. Asthma severity may vary with the season. For asthmatic patients with predictable seasonal allergies, prescribe inhaled corticosteroids for a few weeks or months beginning 2 to 3 weeks before usual symptom onset. Successful long-term management requires identification and control of asthma triggers, such as cigarette smoke, house dust mites, cockroaches, molds, and animal dander. Removing triggers or minimizing the patient's exposure to them may allow improved asthma control with lower dosages of corticosteroids.
