Sažetak
The article gives a critical review of the main epidemiological features of allergic diseases, their frequency, distribution and etiologic background as well as the possibilities of prevention and control, based on current literature. Statistical data for Croatia, collected by the Croatian National Institute of Public Health, are used to present actual epidemiological situation in Croatia. Basic descriptive epidemiological methods were used to express age and sex distribution, etc. In comments and review of preventive measures, our own epidemiological experiences and experience acquired on creating the national programs of health measures were used. The genesis of allergies usually implies the influence of various potent environmental allergens such as proteins or smaller molecules attached to proteins (haptens) through repeat or continuous exposure by contact, alimentary or respiratory route, and parenteral route as most efficient (mucous membrane exposure is similar to parenteral exposure). In addition, almost all substances from our environment may, under certain circumstances, become allergens and produce allergic reaction. Individual constitution that is inherited also plays a role. Allergic diseases are present all over the world, however, with variable frequency. Response to an allergen is generally the same, causing distinct allergic diseases like urticaria, anaphylactic shock, asthma, etc., while the main allergens can be different. It is estimated that 30%-40% of all people have some type or manifestation of allergy. According to our Institute data, in Croatia hospitalization was mostly required for allergic urticaria and allergic asthma, followed by Quincke’s edema. Optimal treatment and appropriate healthcare structure are essential for efficient control and prevention of allergic diseases. The main direct elements are as follows: well organized emergency service for anaphylactic and other severe conditions; health education expected from all levels of healthcare system; allergology outpatient services available; and sufficient hospital capacities. An indirect yet important element is optimal drug prescribing and usage practice. Other specific public health measures include: pollen air concentration monitoring by public health institutes; information on particular allergen presence and intensity via public media; and control of potential allergen emission into the environment, especially air. People will, as always, find ways to adapt themselves and cope with allergies, with medical profession helping them by identifying the reasons causing allergic diseases and developing successful measures of treatment, prevention and control.
