Tree-pollen allergy is efficiently treated by short-term immunotherapy (STI) with seven preseasonal injections of molecular standardized allergens.

1998

The efficacy and tolerance of short-term immunotherapy (STI) by seven preseasonal injections of tree-pollen allergens (ALK7 Fruhbluhermischung) was investigated in a double-blind, placebo-controlled, multicenter study with 111 rhinoconjunctivitis patients. Nasal and bronchial symptoms simultaneously analyzed, and nasal symptoms as a single end point, but not the overall score of nasal, bronchial, and conjunctival symptoms, showed a significantly lower increase with STI during birch-pollen exposure (both P=0.033, n=105, Mann-Whitney U-test). However, a selective analysis with patients from centers with high recruitment figures (n> or =10 patients, n=29 STI, n=32 placebo) showed a significant…

Late reactions to patch test preparations with reduced concentrations of p-phenylenediamine : a multicentre investigation of the German Contact Derma…

2011

Background. p-Phenylenediamine (PPD) 1% in petrolatum has been shown in a prospective study to elicit late reactions in 1.5% of routine patch tests, which may be indicative of patch test sensitization. Objectives. To assess the frequency of late reactions to reduced PPD patch test concentrations. Methods. In 1838 patients, PPD was tested at three concentrations (0.5% pet., group I; 0.4% pet., group II; and 0.35% pet., group III). Patch tests were read on D1 (D2) to D3 (D4); additional late readings were performed on D7, D14, and D21. Patients who were not able to return for all scheduled late readings were telephoned on D7, D14, and D21, and questioned about a reaction at the patch test sit…

Prevalence of Sensitization toAnisakis simplexAmong Professionally Exposed Populations in Sicily

2012

Anisakis simplex (AS) is a cause of allergic sensitization and potential occupational risk is suggested in fishermen and workers assigned to fish processing and sale. A cross-sectional study was conducted in order to assess possible health effects of occupational exposure to AS in workers recruited from western Sicily fisheries sector. Social, demographic, and occupation-related data were collected. Serum total immunoglobulin E (IgE) and specific IgE levels to AS (threshold >0.35 kU/L) were determined by an fluoroimmunoassay technique. Ninety-four subjects with potential occupational exposure (fishmongers, fishermen, fish industry employees) were recruited. Specific AS IgEs were detected in…

RhinAsthma patient perspective: a short daily asthma and rhinitis QoL assessment.

2012

Background The present study aimed to develop a short validated patient-completed questionnaire, the RhinAsthma Patient Perspective (RAPP), to assess the health-related quality of life (HRQoL) in patients with asthma and comorbid allergic rhinitis in clinical practice. Methods A provisional RAPP questionnaire was formed from candidate items identified through retrospective analysis of 333 RHINASTHMA questionnaires. This was then tested on 150 asthma patients with allergic rhinitis. Results Psychometric analyses identified eight items fitting a unidimensional model to form RAPP. Internal consistency (Cronbach's alpha coefficient > 0.8) and agreement with RHINASTHMA (r = −0.31, P = 0.0001) we…

The Urticaria Activity Score-Validity, Reliability, and Responsiveness.

2018

Background Chronic spontaneous urticaria is characterized by fluctuating symptoms. Its activity is assessed with the urticaria activity score (UAS). Two versions of the urticaria activity score used for 7 consecutive days (UAS7) are available: (1) The guideline-recommended UAS7, with once-daily documentation, and (2) the UAS7TD, with twice-daily documentation. Objective To better characterize both UAS7 versions with regard to their validity, reliability, sensitivity to change, minimal important difference (MID), and smallest detectable change (SDC). Methods One hundred thirty adult patients with chronic spontaneous urticaria completed both UAS7 versions, the Patients Global Assessment (PatG…

Double-blind, randomized, placebo-controlled trial of allergen-specific immunotherapy with the major allergen Alt a1

2019

Background: There have been few studies conducted on the efficacy and safety of specific immunotherapy with allergen extracts of fungi compared with other allergen extracts, and there are no data on the major allergen Alt a 1 of the fungus Alternaria alternata. Objectives: We sought to evaluate the efficacy and safety of subcutaneous immunotherapy with 2 different doses of Alt a 1 in patients with rhinoconjunctivitis caused by sensitization to A alternata. Method: We performed a multicenter, randomized, double-blind, placebo-controlled trial with Alt a 1 administered subcutaneously in patients with allergic rhinoconjunctivitis with or without controlled asthma aged 12 to 65 years. Three gro…

Severe chronic spontaneous urticaria in children – treatment options according to the guidelines and beyond – a 10 years review

2020

This is a retrospective study of 18 children with chronic spontaneous urticaria (CSU), where standard therapies, including up-dosing of antihistamines and omalizumab, were unable to cure the disease and where alternative strategies with experimental and off-label medication had to be used. Being aware that our questionnaire is validated only for elder children or adults, we utilized the UAS7 to monitor disease control with the help of the parents. The UAS7 score decreased from a mean of 25 to an average of 13 after 8 weeks of therapy in 13 patients. Five patients had no significant reduction of UAS7 by week 8. In two of five patients, where periodic improvement was seen, omalizumab therapy …

Omalizumab (Xolair®) improves quality of life in adult patients with allergic asthma: a review

2003

Abstract Physicians are increasingly aware that asthma causes significant impairment of the patient's physical, psychological, and social well-being. Whilst standard clinical endpoints provide significant information on airway status during treatment, it is important to determine whether such improvements overcome the functional impairment that patients have to deal with on a daily basis. As such, assessment of health-related quality of life (QoL) is an important aspect of asthma management in clinical practice. Omalizumab (Xolair ® ) is a recombinant humanized monoclonal anti-immunoglobulin E (IgE) antibody that represents a new therapeutic approach to IgE-mediated diseases such as allergi…
