The risk factors for asthma and its exacerbations in childhood are discussed. The genetic factors and environmental risk factors. These are biogenic, including influence of allergens - house dust mites, animal allergens, pollen and mould allergens, microbial - bacterial and viral. Environmental risk factors - industrial and traffic pollution, tobacco smoke exposure, risk factors of inappropriate alimentation, obesity. The preventive measures of particular risk factors are considered, primary, secondary and tertiary prevention. Paediatricians, allergists and pneumologists should strive for a greatest possible prevention of allergic and nonallergic asthma. Source


In patients with a long history of angioedema without urticaria was diagnosed hereditary angioedema (HAE) and launched a long-term prophylactic treatment with attenuated androgens danazol. The patient was at the time of diagnosis of HAE, unfortunately, also treated with ACE inhibitors for hypertension. After initiation of the therapy with danazol, and simultaneously change in therapy of hypertension with discontinuation of ACE inhibitors, the status of the patient improved markedly in recent years and symptoms of HAE appeared sporadically only during infection or following surgery. Since 2001 the patient after wasp or bee sting had a large edema and patient thought that these are attacks of HAE. However at the turn of the millennium the patient had an anaphylactic reaction after a Hymenoptera insect sting and in allergy testing were confirmed sensitization to Hymenoptera venom and we started the treatment with allergen immunotherapy. Conclusion: Patients with HAE have discontinued treatment with ACE inhibitors because ACE inhibitors trigger angioedema. Patients with HAE sometimes poorly differentiated between HAE attack and allergy attack with similar clinical manifestations. The possibility of coincidence of two such serious diagnoses must be considered. Source

Food allergy prevalence has increased in recent years. Currently, it is described to be present in 7% of children and 5% of adults. The spectrum of most frequent allergens has changed and widened, symptoms are becoming more severe. There are significant geographical differences in the incidence of food allergy, types of senzitization and symptoms. Accordingly, the most common causes of food anaphylaxis are different in respective regions. No recent relevant epidemiological data on occurence of food allergy in Czech Republic are available. DAFALL registry (Database of Food Allergies) has been founded on iniciative of Immuno-flow, s.r.o., to collect data from patients with newly diagnosed food allergy. In this report we present results from 275 patients enrolled into the registry during the first six months of its existence. Source

Insect sting is one of the most often cause of anaphylaxis, which with its unpredictable, acute and potentially life-threatening course, represents a serious medical problem. Proper diagnosis and treatment of hymenoptera venom allergy is therefore extremely important and the key role belongs into hands of experienced allergist. EAACI position paper on the diagnosis of hymenoptera venom allergy from 2005 is still valid. Precise personal history, skin testing and the determination of specific IgE antibodies to bee and wasp venoms remains the gold standard of examination. The definite differentiation between bee and wasp venom allergy is often complicated by frequently observed double positivity of commonly used test results, which complicate the choice of relevant venom for immunotherapy. For precise diagnosis in patients, with double positivity of the test results, basophile activation test and component resolved diagnosis are used. In the field of hymenoptera venom allergy, the component resolved diagnosis is the most up to date diagnostic method, which is the object of intensive research and is quite promising for the future.

Molecular diagnosis of allergy is a modern approach which enables new insights into the sensitization profiles of allergic patients. Microarray technology provides detection of sensitization to a higher number of molecules in frame of one test. We used this tool in the sensitization analysis to pollen derived molecules in patients coming from our region. 1096 patients sensitized to at least one pollen derived molecule were included into the analysis. The most frequent sensitization rate (80.8%) was found to grass pollen derived molecules (Phl p 1 66.3%), the second most frequent (54.9%) was to betulaceae pollen derived molecules (Bet v 1 52.5%). Sensitization rates to cupressaceae and plane tree pollen derived molecules were observed unexpectedly frequently (in 14.0%, resp. 15.3%). Sensitization rates to other pollen derived molecules were in the expected ranges. Sensitizations to cross-reacting molecules (panallergens) were observed less frequently than reported from southern countries. Molecular diagnosis of allergy gives a more precise and comprehensive insight into the sensitization profile of a patient, allowing better understanding of the sensitization process, and the explored data may help to the optimization of allergen specific immunotherapy.
