Aim: To determine the prevalence and to estimate factors associated with food hypersensitivity in young children of the Lviv region in Ukraine.

Methods: A prospective cross-sectional survey study was conducted between 2016 and 2017 in the Lviv region of Ukraine. A specially designed questionnaire about food hypersensitivity of young children developed and validated by M. J. Flokstra-de Blok was used after translation into the Ukrainian language. The questionnaire included 34 questions, grouped into general and detailed information. Parents of children aged 0–3 years were asked to complete the questionnaire at pre-schools and medical institutions.

Results: Among 4,500 distributed questionnaires, 3,214 (71%) were completed and processed. Parents reported that 25% of their young children had food hypersensitivity. According to the survey the most common agents involved in food hypersensitivity in young children were cow's milk (34%), egg (28%), and wheat (24%). Hypersensitivity to milk occurred in 50% of children in the age group of 1–2 years. Regional differences associated with food hypersensitivity were also found. Namely, in the Carpathians, there was more hypersensitivity to fish (27%) and honey (22%) than in other regions, while hypersensitivity to soy was detected mostly in Lviv City residents (8.5%). Unknown causes of food hypersensitivity were highly reported (34%) in the Carpathians.

Conclusion: Prevalence and some distinctiveness of food hypersensitivity revealed in four geographic and climate zones as well as in Lviv City have a considerable practical use for formulation of recommendations for children with food hypersensitivity.

To date, various manifestations of allergic reactions and diseases are registered in 15-35% of the population according to the World Health Organization, and in recent years there has been a constant tendency to increase [1]. The first sign of allergic pathology in children, as a rule, is a food allergy, which is mainly manifested by atopic dermatitis. According to official statistics, the rate of atopic dermatitis in Ukraine is known to range from 3 to 10 per 1000 children [2]. However, the results obtained in some regions of our country according to studies under the standardized international program ISAAC (International Study of Asthma and Allergies in Childhood), exceed the above figures by 5-10 times [3]. This situation can be explained by the presence of terminological differences in the interpretation of atopic dermatitis in children, different methodological approaches to statistical research, clinical and age-related polymorphism of the disease. The development of atopic march can begin with a food allergy, so all efforts of physicians should be directed to prevent the transformation of skin forms into respiratory ones and provide the patient and his/her parents with a full quality of life [4,5]. The “School of Atopy” operates under the auspices of the MNPE “Lviv City Children’s Clinical Hospital” and the Lviv City Children’s Allergological Center, where a model of a multidisciplinary approach to the management of patients with food allergies according to European standards was reproduced. Every patient treated for food allergies goes from diagnosis to treatment. Of course, great emphasis is placed on preventing and predicting the development of atopic march in children and improving the quality of life of patients and their parents. 

У звʼязку із необхідністю модернізації клінічних і профілактичних процесів у галузі охорони здоровʼя (ОЗ) України, орієнтованих на підвищення якості медичного обслуговування населення, виникла потреба пошуку нових форм і методів якісного практично-орієнтованого аналізу функціонування медичної служби, що дозволить підвищити задоволеність пацієнтів під час отримання медичної допомоги (МД) та медичних послуг. Одним із шляхів для підвищення рівня задоволеності пацієнтів якістю наданої МД є проведення клінічного аудиту (КА), який зараз набуває особливої популярності.

Adverse reproductive outcome before term is a polyetiological pathology associated with demographic crisis. Some adverse outcomes include perinatal and neonatal infant mortality, major morbidity and mortality of children under two years, violation of psychomotor and physical development, cognitive disturbances and disability of children under age five. Finding ways to solve these issues remain a priority. The research involved two female groups. The experimental group included 403 women after the involuntary termination of pregnancy, premature birth or in case of threat of miscarriage; the control group included 402 women with physiological course of pregnancy and parturient with full-term pregnancy. The study required the application of systemic approaches and methods including structural, logical, medical and statistical analyses. The survey revealed more than 20 infectious risk factors and more than 70 factors of extragenital origin. The most significant infectious pathologies included COVID-19 (36.23 ± 2.29% and 14.93 ± 1.78%), herpes type 1 (5.96 ± 1.18% and 1.0 ± 0.50%), toxoplasmosis (4.22 ± 1.0% and 1.0 ± 0.50%) and chlamydial infection (4.22 ± 1.0% 0.50 ± 0.35%) in the experimental and control groups, respectively (P < 0.01). The most significant extragenital pathologies involved autoimmune thyroiditis (8.68 ± 1.40% and 0.75 ± 0.43%), type 1
diabetes mellitus (2.23 ± 0.74% and 0%) and allergic rhinitis/sinusitis (3.97 ± 0.97% and 0.50 ± 0.35%) in the experimental and control groups, respectively (P < 0.01). Obtained results will be used in the development of a personified risk-oriented model for the prevention of preterm pregnancy loss.
