        <p>Purpose of study: to evaluate the clinical efficacy of vitamin D supplementation in the complex treatment of bronchial asthma in children. Materials and methods: the study involved 60 children with bronchial asthma. Of these, 13 (21.6%) had a severe persistent form of asthma (group I), 33 (55%) had a moderate form (group II), and 14 (23%) children were observed with a mild persistent form (group III). One of the criteria for participation in the study was the absence of conditions requiring intensive care. The control group consisted of 50 children with moderate acute obstructive bronchitis and no history of allergic diseases. Informed parental consent was obtained for all study participants. The level of the metabolite 25(OH)D in the blood of children was used to analyse vitamin D status. Results and discussion: the concentration of vitamin D (25(OH)D) in the blood serum was assessed before and after treatment using an enzyme immunoassay. According to the recommendations of the US Institute of Medicine, a 25(OH)D level below 20 ng/ml indicates deficiency and 21–30 ng/ml indicates insufficiency. Conclusions: the combination of basic therapy and vitamin D has demonstrated effectiveness, reducing the risk of asthma exacerbations. The inclusion of vitamin D in complex treatment has a positive effect on the course of the disease and its dynamics, which helps to improve treatment and prevention measures.</p>

        <p>Цель исследования: оценить клиническую эффективность применения витамина D в комплексном лечении бронхиальной астмы у детей. Материалы и методы: в исследование были включены 60 детей с бронхиальной астмой. Из них 13 (21,6%) имели тяжёлую персистирующую форму астмы (I группа), 33 (55%) — среднетяжёлую форму (II группа), 14 (23%) детей наблюдались с лёгкой персистирующей формой (III группа). Одним из критериев участия в исследовании было отсутствие состояний, требующих интенсивной терапии. Контрольную группу составили 50 детей со среднетяжёлым острым обструктивным бронхитом без аллергических заболеваний в анамнезе. Для всех участников исследования было получено информированное согласие родителей. Для оценки уровня витамина D использовался метаболит 25(OH)D в крови детей. Результаты и обсуждение: концентрация витамина D (25(OH)D) в сыворотке крови оценивалась до и после лечения методом иммуноферментного анализа. Согласно рекомендациям Института медицины США, уровень 25(OH)D ниже 20 нг/мл свидетельствует о дефиците, а 21–30 нг/мл — о недостаточности. Выводы: сочетание базисной терапии и витамина D продемонстрировало эффективность, снижая риск обострений астмы. Включение витамина D в комплексное лечение оказывает положительное влияние на течение заболевания и его динамику, что способствует совершенствованию мер лечения и профилактики.</p>

        <p>Tadqiqot maqsadi: bolalardagi bronxial astmani kompleks davolashda vitamin D qo‘shimchasining klinik samaradorligini baholash. Materiallar va metodlar: tadqiqotga bronxial astma bilan og‘rigan 60 nafar bola jalb etilgan. Ulardan 13 nafari (21,6%) og‘ir persistent shakldagi astma (I guruh), 33 nafari (55%) o‘rta og‘irlikdagi shakl (II guruh), 14 nafari (23%) yengil persistent shakldagi astma bilan kuzatildi (III guruh). Tadqiqotda ishtirok etish mezonlaridan biri jadal yordamga muhtoj holatlarning yo‘qligi edi. Nazorat guruhi o‘rta og‘irlikdagi o‘tkir obstruktiv bronxit bilan kasallangan va allergik kasalliklar anamnezi bo‘lmagan 50 nafar boladan iborat edi. Barcha ishtirokchilarning ota-onalaridan tushuntirilgan rozilik olindi. Bolalarda vitamin D statusini baholash uchun qonda 25(OH)D metaboliti darajasi aniqlandi. Natijalar va muhokama: qon zardobidagi vitamin D (25(OH)D) konsentratsiyasi davolanishdan oldin va keyin ferment immunoanaliz usulida baholandi. AQSh Tibbiyot institutining tavsiyalariga ko‘ra, 25(OH)D darajasi 20 ng/ml dan past bo‘lsa yetishmaslik, 21–30 ng/ml bo‘lsa kamlik ko‘rsatkichi hisoblanadi. Xulosalar: asosiy terapiya bilan vitamin D ning birgalikdagi qo‘llanilishi samarali ekanligini ko‘rsatdi va astma zo‘rayishlari xavfini kamaytirdi. Vitamin D ni kompleks davolashga kiritish kasallikning kechishi va dinamikasiga ijobiy ta‘sir ko‘rsatadi, bu esa davolash va profilaktika choralarini yaxshilashga yordam beradi.</p>
