Clopidogrel Desensitization: Background and Recommendations for Use of a Rapid (4 Hour) Protocol.

The purpose of this section is to educate the reader on how to successfully manage patients with a hypersensitivity reaction to clopidogrel using desensitization protocol based on various published protocols. Additionally, we will define drug desensitization, and describe the possible mechanism of how desensitization may function as alternative medication. The indications/contraindications for desensitization will be reviewed.

Effect of misoprostol on patients with aspirin-exacerbated respiratory disease undergoing aspirin challenge and desensitization.

Background: Prostaglandin E (PGE) is an anti-inflammatory compound that inhibits 5-lipoxygenase activity. Diminished PGE regulation in aspirin-exacerbated respiratory disease (AERD) leads to respiratory reactions on cyclooxygenase 1 inhibition. In vitro studies have found that exogenous PGE stabilizes inflammatory mediator release.

The Utility of the Reflux Symptom Index for Diagnosis of Laryngopharyngeal Reflux in an Allergy Patient Population.

Background: Laryngopharyngeal reflux (LPR) is associated with asthma, vocal cord dysfunction, cough, postnasal drainage, and throat irritation. The Reflux Symptom Index (RSI) is a clinical tool to predict the presence of LPR, but a threshold RSI score has never been validated for the diagnosis of LPR in an allergic patient population.

Objective: To identify the optimal threshold RSI score predictive of LPR in an allergy clinic population.

Use of a composite symptom score during challenge in patients with suspected aspirin-exacerbated respiratory disease.

Background: Aspirin-exacerbated respiratory disease is characterized by asthma, chronic rhinosinusitis, nasal polyposis, and sensitivity to aspirin and other nonsteroidal anti-inflammatory drugs. Confirmation of the diagnosis requires provocation challenge with resulting upper and/or lower airways reactivity. Currently, determination of a positive challenge result is based solely on clinical judgment that synthesizes subjective symptoms and objective measures, as a concomitant increase in nasal or bronchial airways resistance is measured in only half of patients.

Performing Aspirin Desensitization in Aspirin-Exacerbated Respiratory Disease.

Aspirin-exacerbated respiratory disease (AERD) is characterized by chronic rhinosinusitis with nasal polyps, asthma, and reactions to cyclooxygenase-1-inhibiting drugs. This condition is often refractory to standard medical treatments and results in aggressive nasal polyposis that often requires multiple sinus surgeries. Aspirin desensitization followed by daily aspirin therapy is an important treatment option, and its efficacy has been validated in multiple research studies.

Improvement in Asthma Control Using a Minimally Burdensome and Proactive Smartphone Application.

Background: Integrated chronic disease treatment models that enable patient self-care and shared treatment decision making have recently been shown to improve medication adherence and outcomes. Smartphone applications (apps) are a readily available means to enable this model, although sustained user engagement remains a challenge.

Objective: To assess the efficacy of improving asthma control using a proactive smartphone app without required regular inputs.

Aspirin-exacerbated respiratory disease: characteristics and management strategies.

Aspirin-exacerbated respiratory disease is a clinical entity comprising chronic rhinosinusitis with nasal polyposis, asthma and intolerance to COX-1 inhibiting drugs. The pathogenesis is not completely understood at this point, but abnormal arachidonic acid metabolism is a key feature in this syndrome. The diagnosis is confirmed only by direct drug challenge.

A genome sequencing program for novel undiagnosed diseases.

Purpose: The Scripps Idiopathic Diseases of Man (IDIOM) study aims to discover novel gene-disease relationships and provide molecular genetic diagnosis and treatment guidance for individuals with novel diseases using genome sequencing integrated with clinical assessment and multidisciplinary case review. Here we describe the operational protocol and initial results of the IDIOM study.

Methods: A total of 121 cases underwent first-tier review by the principal investigators to determine whether the primary inclusion criteria were satisfied, 59 (48.

Update on aspirin desensitization for chronic rhinosinusitis with polyps in aspirin-exacerbated respiratory disease (AERD).

Aspirin-exacerbated respiratory disease (AERD) is a clinical condition which results in adverse upper and lower respiratory symptoms, particularly rhinitis, conjunctivitis, bronchospasm, and/or laryngospasm, following exposure to cyclooxygenase-1 (COX-1) inhibiting drugs, namely aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs). A provocative aspirin challenge is the gold standard for diagnosis of AERD. Aspirin desensitization and continuous aspirin therapy has been highly efficacious in those patients with suboptimal control of their disease on current available pharmacotherapy or those with other underlying conditions (i.

Supraesophageal Reflux: Correlation of Position and Occurrence of Acid Reflux-Effect of Head-of-Bed Elevation on Supine Reflux.

Background: Supraesophageal reflux of gastric contents can contribute to perennial nasopharyngitis, cough, and asthma. However, effective treatment strategies for supraesophageal reflux disease (SERD) remain inadequately defined.

Objective: The purpose of this study is to assess the prevalence and timing of SERD and to investigate the efficacy of head-of-bed elevation in its treatment.

Food allergy: a practice parameter update-2014.

This parameter was developed by the Joint Task Force on Practice Parameters, representing the American Academy of Allergy, Asthma & Immunology (AAAAI); the American College of Allergy, Asthma & Immunology (ACAAI); and the Joint Council of Allergy, Asthma & Immunology (JCAAI). The AAAAI and the ACAAI have jointly accepted responsibility for establishing "Food Allergy: A practice parameter update-2014." This is a complete and comprehensive document at the current time.

Supraesophageal reflux disease: a review of the literature.

Supraesophageal reflux disease (SERD), defined as reflux proximal to the upper esophageal sphincter, is a common cause of morbidity of the upper aerodigestive tract, including rhinitis, laryngitis, cough, postnasal drip, and throat clearing. Although SERD has a high prevalence, the ideal means of diagnosing and treating the disease remain poorly defined. Evolving pH monitoring technology and a body of literature with conflicting reports regarding the best means for measuring and interpreting supraesophageal acidic reflux complicates the diagnosis of SERD.

Prevalence of sensitivity to food and drug additives in patients with chronic idiopathic urticaria.

Background: Chronic idiopathic urticaria (CIU) is defined as the presence of urticaria most days of the week for a period of 6 weeks or longer. There have been reports of food additive sensitivity in CIU previously, but the prevalence has not been precisely determined.

Objective: To determine the prevalence of reactions to food and drug additives in patients with CIU.

Cardiovascular prophylaxis and aspirin "allergy".

Aspirin is an important antiplatelet agent in the treatment of cardiovascular disease. Aspirin "allergy" often directs the physician away from this potentially life-saving modality. The majority of patients with a history of "reactions to aspirin" have aspirin/nonsteroidal anti-inflammatory drug (NSAID)-induced gastritis, easy bruisability, or other side effects.

Approach to patients with aspirin hypersensitivity and acute cardiovascular emergencies.

The occurrence of an emergent need for aspirin therapy in an aspirin or nonsteroidal anti-inflammatory drug (NSAID)-"allergic" individual presents one of the more challenging situations the allergist may face. A common request is for the allergist to evaluate an acutely ill patient in a monitored hospitalized setting with a vague and remote history of a "reaction to aspirin." Because of significant diagnostic limitations, introducing aspirin can be very difficult.

The united allergic airway: connections between allergic rhinitis, asthma, and chronic sinusitis.

Background: The united allergic airway is a theory that connects allergic rhinitis (AR), chronic rhinosinusitis, and asthma, in which seemingly disparate diseases, instead of being thought of separately, are instead viewed as arising from a common atopic entity.

Objective: This article describes patients with such diseases; explores ideas suggesting a unified pathogenesis; elucidates the various treatment modalities available, emphasizing nasal corticosteroids and antihistamines; and provides an update of the literature.

Methods: A literature review was conducted.

Aspirin-exacerbated respiratory disease: burden of disease.

Aspirin-exacerbated respiratory disease (AERD) is characterized by adult onset of asthma, chronic rhinosinusitis (CRS), nasal polyposis, and aspirin sensitivity. In this syndrome, each disease component has deleterious effects on the patient's health and quality of life. Latest figures from the Centers for Disease Control indicate 8.

Assessment of sensitization risk of a laundry pre-spotter containing protease.

When proteolytic enzymes were first introduced to common laundry detergents in the 1960s, their ability to cause hypersensitivity due to exposure by inhalation was soon recognized as a problem, especially for production workers. Subsequently, formulations and manufacturing methods were developed to minimize exposure to enzymes via inhaled dust particles. Although detergents containing proteases are now considered safe for consumers, the experience with laundry pre-spotter products is not as extensive.
