Allergic fungal rhinosinusitis.

Allergic fungal rhinosinusitis (AFRS) is a subset of chronic rhinosinusitis with nasal polyps (CRSwNP) characterized by antifungal IgE sensitivity, eosinophil-rich mucus (ie, allergic mucin), and characteristic computed tomographic and magnetic resonance imaging findings in paranasal sinuses. AFRS develops in immunocompetent patients, with occurrence influenced by climate, geography, and several identified host factors. Molecular pathways and immune responses driving AFRS are still being delineated, but prominent adaptive and more recently recognized innate type 2 immune responses are important, many similar to those established in patients with other forms of CRSwNP.

The spectrum of allergic fungal diseases of the upper and lower airways.

Fungi cause a wide spectrum of fungal diseases of the upper and lower airways. There are three main phyla involved in allergic fungal disease: (1) Ascomycota (2) Basidiomycota (3) Zygomycota. Allergic fungal rhinosinusitis (AFRS) causes chronic rhinosinusitis symptoms and is caused predominantly by Aspergillus fumigatus in India and Bipolaris in the United States.

Attitudes toward allergy: what do the pediatricians think?

Background: In 1971, we published a survey regarding pediatricians' attitudes toward the field of allergy/immunology (A/I). Results indicated general attitudes and practices fell short of what most allergist-immunologists would hope. We revisited this in 1998 to determine how pediatricians' attitudes toward A/I had changed nearly 3 decades later.

Allergic bronchopulmonary aspergillosis.

There remains a lack of agreement on diagnostic criteria and approaches to treatment of patients with allergic bronchopulmonary aspergillosis (ABPA). The results of a survey of American Academy of Allergy, Asthma, & Immunology members regarding these 2 issues are presented and compared for concordance with published recommendations. The literature was reviewed for pertinent reports, and an electronic survey was conducted of American Academy of Allergy, Asthma, & Immunology members and fellows regarding diagnostic criteria, numbers of patients evaluated for ABPA, and treatment approaches.

Chronic bilateral pruritic arm dermatitis in a 61-year-old woman.

A 61-year-old woman presented to our Allergy/Immunology clinic for pruritic dermatitis of both arms since 2006. Initial symptoms included pruritus and burning dysesthesias of the upper extremities without a rash. Months later an excoriated, papular rash developed along the upper extremities.

Fungi and allergic lower respiratory tract diseases.

Asthma is a common disorder that in 2009 afflicted 8.2% of adults and children, 24.6 million persons, in the United States.

Update on occupational rhinitis and asthma.

The workplace is emerging as an increasingly important venue for the development of rhinitis and asthma. There is no question that allergic diseases of the respiratory tract caused by occupational exposure are on the increase. The clinician's diagnostic index of suspicion must be high so that a diagnosis of occupational rhinitis and/or asthma can be made in a timely fashion.

Allergic bronchopulmonary aspergillosis in asthma and cystic fibrosis.

Allergic bronchopulmonary aspergillosis (ABPA) is a Th2 hypersensitivity lung disease in response to Aspergillus fumigatus that affects asthmatic and cystic fibrosis (CF) patients. Sensitization to A. fumigatus is common in both atopic asthmatic and CF patients, yet only 1-2% of asthmatic and 7-9% of CF patients develop ABPA.

Distinctions between allergic fungal rhinosinusitis and chronic rhinosinusitis.

Background: Recent reports have attempted to redefine the accepted diagnostic criteria for allergic fungal rhinosinusitis (AFRS), a form of chronic rhinosinusitis (CRS) with nasal polyps. As a result, the existence of AFRS as a distinct entity has been questioned, suggesting that allergy has no role in CRS with sinonasal eosinophilia, and the condition should be referred to as eosinophilic fungal rhinosinusitis. The purpose of the study was to differentiate between AFRS and CRS by studying antibody responses in these two clearly defined patient groups.

Special considerations in treatment of allergic rhinitis in the elderly: role of intranasal corticosteroids.

Once viewed as a "young person's disease," allergic rhinitis (AR) is becoming increasingly common in the elderly. Effective treatment is necessary not only to minimize the impact of AR in the older population, but to prevent the onset or exacerbation of asthma. This review was conducted to examine the clinical evidence regarding the efficacy and safety of therapies for AR in the elderly.

Treating rhinitis in the older population: special considerations.

Rhinitis in the elderly is a common but often neglected condition. Structural changes in the nose associated with aging, predisposes the elderly to rhinitis. There are a number of specific factors that affect medical treatment of the elderly including polypharmacy, cognitive dysfunction, changes in body composition, impairment of liver and renal function and the cost of medications in the face of limited resources.

Criteria to screen for chronic sinonasal disease.

Background: Sinusitis and rhinitis are associated with uncontrolled asthma. There are no simple, validated tools to screen for these diseases. The objective of this study was to assess instruments to assist in the diagnosis of chronic sinonasal disease.

The upper and lower airways: the epidemiological and pathophysiological connection.

The upper and lower airways do not exist as anatomically and functionally distinct areas. There are important relationships between both the nose and the paranasal sinuses and asthma. Both allergic rhinitis and rhinosinusitis may impact bronchial asthma.

Asthma symptom re-emergence after omalizumab withdrawal correlates well with increasing IgE and decreasing pharmacokinetic concentrations.

Background: Physicians have questioned whether omalizumab can be discontinued or the dose reduced after clinical improvement is seen in patients with severe asthma.

Objectives: To examine the relationships among omalizumab, free IgE, and clinical outcomes in a randomized, placebo-controlled trial in patients with severe persistent allergic asthma following a posology based on pretreatment total IgE and body weight.

Methods: A pharmacokinetic-pharmacodynamic binding model was used to calculate free IgE, omalizumab, and total IgE concentrations during the 28-week treatment and 16-week follow-up of the INvestigation of Omalizumab in seVere Asthma TrEatment (INNOVATE) study.

Are fish oil supplements safe in finned fish-allergic patients?

Fish oil supplements are popular alternative medicines. Many manufacturers label their products with the warning "avoid this product if you are allergic to fish." The objective of this study was to determine if finned fish (FF)-allergic patients could safely tolerate fish oil supplements.

The tale of the allergist's life: a series of interesting case reports.

The practicing allergist has the unique opportunity to see an extraordinary variety of fascinating patients. Identifying the precise cause of the patient's complaints makes for a satisfying intellectual endeavor. This is exemplified by the description of nine cases seen in a university allergy clinic.

Seafood allergy and radiocontrast media: are physicians propagating a myth?

Background: Recent surveys have indicated that the misconception that seafood allergy confers a disproportionately increased risk of adverse reactions to radiocontrast media remains pervasive among physicians and patients. One possible explanation for the persistence of this notion is that physicians responsible for radiocontrast administration are inadvertently contributing to its propagation.

Methods: An anonymous survey was sent to 231 faculty radiologist and interventional cardiologists at 6 Midwest academic medical centers.

Hypersensitivity pneumonitis secondary to residential exposure to Aureobasidium pullulans in 2 siblings.

Background: Hypersensitivity pneumonitis (HP) is an immune-mediated hypersensitivity reaction to a variety of inhaled particles that may lead to acute, subacute, or chronic interstitial pneumonitis and possibly end-stage lung disease. Avian antigens most commonly cause HP in children, but fungi have also been implicated.

Objective: To describe a 15-year-old girl and her 6-year-old brother who developed HP from residential exposure to Aureobasidium pullulans.

HLA-DRB1 alleles control allergic bronchopulmonary aspergillosis-like pulmonary responses in humanized transgenic mice.

Background: Allergic bronchopulmonary aspergillosis (ABPA) is a lung hypersensitivity disease mediated in part by CD4(+) T(H)2 cells. There is a significant association between ABPA and the HLA-DR2 genotypes DRB1(*)1501 and DRB1(*)1503, whereas resistance might be associated with HLA-DRB1(*)1502.

Objective: We sought to elucidate the role of HLA-DR alleles in allergic inflammation in lungs.

What the allergist should know about hypersensitivity pneumonitis.

Hypersensitivity pneumonitis (HP) appears to be an underdiagnosed condition. It may masquerade as recurrent pneumonia, idiopathic pulmonary fibrosis, Haman-Rich disease, or interstitial pneumonitis. The nature of the disease depends on the immunologic reactivity of the host and the intensity and chronicity of exposure.
