Co-occurrence of otitis media with effusion and another environment-dependent disease (selected allergic conditions).

Introduction: Otitis media eith effusion (OME) is an inflammatory condition of the middle ear that involves accumulation of sterile fluid or effusion in the tympanic cavity with the tympanic membrane intact. The pathophysiology of OME is undoubtedly multifactorial. Aim: To assess the co-occurrence of OME, allergic rhinitis, and asthma. Material and methods: The study involved a group of 18,617 subjects aged 6-7 years, 13-14 years, or 20-44 years. ECRHS and ISAAC questionnaires, validated and adopted for Polish conditions, were used in the study. Results: OME increases the risk of developing allergic rhinitis by nearly two-fold (OR = 2.07, 95% CI: 1.738-2.479 in 6-7-year-olds; OR = 1.61, 95% CI: 1.299-1.995 in 13-14-year-olds, and OR = 1.55, 95% CI: 1.262-1.83 in 20-44-year-olds). Protective factors against otitis media with effusion include the number of siblings (the more children in the family, the higher the risk of chronic OM; OR = 2.00, 95% CI: 1.15-1.346) and consumption of dairy products rich in lactic acid bacteria. Conclusions: OME significantly more often co-exists with other conditions, particularly allergic rhinitis.

Evaluation of selected aspects of the hygiene hypothesis and their effect on the incidence of allergy.

OBJECTIVES: The development of allergic conditions is largely dependent on the interactions between genetic (individual genetic predisposition) and environmental factors (exposure to risk factors). The aim of this study was an attempt to assess the influence of selected elements of the hygiene theory in the development of allergic diseases such as allergic rhinitis and asthma. MATERIAL AND METHODS: The study group consisted of 5518 women and 3868 men. The method that was used was the European Community Respiratory Health Survey II and International Study of Asthma and Allergies in Childhood questionnaire validated and adapted to Central and Eastern European conditions. The project was conducted in 8 urban areas (Gdansk, Wroclaw, Poznan, Katowice, Kraków, Lublin, Bialystok, Warsaw) and 1 rural area (Krasnystaw county). This study had 2 stages; the first stage involved grouping the 22 500 respondents based on their questionnaire responses with the use of a Personal Digital Assistant (PDA); the second stage involved 7000 subjects, who underwent additional assessments: skin prick tests (birch, grasses/cereals, Dermatophagoides pteronyssinus and Dermatophagoides farinae, molds [set I: Botrytis cinerea, Cladosporium herbarum, Alternaria tenuis, Curvularia lunata, Fusarium moniliforme, Helminthosporium], molds [set II: Aspergillus fumigatus, Mucor mucedo, Penicillium notatum, Pullularia pullulans, Rhizopus nigricans, Serpula lacrymans], cat, dog, molds Cladosporium herbarum, Alternaria tenuis) and spirometry tests. RESULTS: The age at which children attend the nursery school is critical to the development of allergic diseases; in allergic rhinitis, the risk of an IgE-dependent reaction is 2 times higher in the second than in the first year of life (p = 0.00147, p < 0.05), while in asthma, having a large number of siblings increases the risk of developing obstructive disease by almost 6 times (p = 0.00316, p < 0.05).The age at which children attend the nursery school is critical to the development of allergic diseases; in allergic rhinitis, the risk of an IgE-dependent reaction is 2 times higher in the second than in the first year of life (p = 0.00147, p < 0.05), while in asthma, having a large number of siblings increases the risk of developing obstructive disease by almost 6 times (p = 0.00316, p < 0.05). CONCLUSIONS: The hygiene theory is particularly applicable and can explain the relationship of selected habits in the development of allergic diseases.

Asthma as a social problem requiring systemic solutions in Poland.

Introduction: Due to its physiopathology and chronic character, asthma constitutes a considerable burden to health care and public health. Aim: The main aim of this study was to determine and present the problems of patients diagnosed with asthma and to suggest solutions to meet the individual and public expectations. Material and methods: The study included 18,874 patients and was part of the System for the Prevention and Early Detection of Allergic Diseases in Poland. The study method was a questionnaire based on the European Community Respiratory Health Survey (ECRHS) and International Study of Asthma and Allergies in Childhood (ISAAC). Results: Nearly 90.1% of patients aged 6-7 years reported periodic difficulty in breathing, with over three episodes per week (3.6 in adults, 3.6 in women, 3.1 in men, 3.3 in urban residents, and 4.6 in rural residents) of reported asthma attacks interrupting patients' sleep. Recent asthma attacks were reported mainly by women living in urban areas. Conclusions: Health problems of asthma patients have a measurable impact on the need to introduce systemic solutions, to ultimately minimize the risk of complications for the individual as well as to minimize the social burden of chronic asthma in Poland.

Prevention of perennial allergic rhinitis in the conception of coordinated healthcare in Poland.

Introduction: The primary prevention is intended to prevent the development of diseases, secondary prevention aims to limit disease progression, and tertiary prevention involves reducing disease-associated symptoms. The purpose of this study was to assess the use of selected forms of secondary prevention by patients diagnosed with perennial allergic rhinitis. Moreover, this paper presents the ways in which the adopted organizational solutions could be utilized as part of coordinated healthcare to benefit patients with perennial allergies. Material and methods: The study population comprised 18,617 respondents, 4783 of whom (including patients allergic to Dermatophagoides pteronyssinus and Dermatophagoides farinae) were qualified to undergo a medical examination. The study used ECRHS and ISAAC questionnaires adapted for Europe. Results: Nearly 20% of patients diagnosed with chronic allergic rhinitis used preventive measures against house dust mites; this is in contrast with 13% in the control group (p = 1.358e-07). The secondary preventive measures most commonly used in the study group were, in descending order of frequency, mattress protectors and anti-dust-mite spray. Undertaking preventive measures was most common among study participants with higher education and residents of large cities. Conclusions: The proportion of patients diagnosed with a dust-mite allergy, who undertook preventive measures against perennial allergic rhinitis, was relatively low. Building, maintaining, and continual strengthening the doctors' relationship with chronic allergy patients may shift the nature of healthcare services more towards preventive measures, for the implementation of which the patient will be co-responsible under the coordinated healthcare system.

The role of the nasal allergen provocation test in local allergic rhinitis cases: a preliminary report.

INTRODUCTION: The current state of knowledge is that allergic rhinitis can occur in two forms. One is allergic rhinitis as a manifestation of a systemic allergy with systemic atopy and positive results of skin prick tests or sIgE tests. The other is local allergic rhinitis (LAR) as a local allergic reaction affecting only the nasal mucosa without systemic atopy. AIM: To attempt to assess the usefulness of the nasal allergen provocation test for the purposes of differential diagnosis and the qualification of LAR patients for therapy. MATERIAL AND METHODS: The subjects in the study were a group of 6 adults diagnosed with LAR on the basis of their medical history and the results of nasal allergen provocation tests, with the allergens being house dust mites (Dermatophagoides pteronyssinus, Dermatophagoides farinae). The methods adopted in the study were a point-based rating scale as a measure of nasal/extranasal complaints and active anterior rhinomanometry. RESULTS: Significant differences (p < 0.05) were observed, using the subjective rating scale, in relation to registered nasal and extranasal complaints in the early phase of the allergic reaction. Similarly, the rhinomanometry method revealed significant differences in nasal resistance values before and after the administration of an allergen. CONCLUSIONS: The nasal allergen provocation test is the only testing tool that objectively measures the degree of the patient's allergic reactions and is useful in qualifying LAR patients for further therapy.
