The successful provision of optimal nutrition in children with serious diseases depends on the right diet, as well as the addition of specialized mixtures for its correction. The aim of the study was to study the effectiveness of supplemental nutrition in hereditary fermentopathy (cystic fibrosis) in children. The work included a three-year follow-up of 69 children aged 3 to 15 years suffering from cystic fibrosis. Patients were divided into two groups: 37 patients with cystic fibrosis group 1, receiving a modified version of treatment with additional enteral nutrition and 32 patients with cystic fibrosis group 2, receiving traditional treatment. The study conducted a comparative analysis of changes in trophic status in patients using nutritional support mixture produced in the Russian Federation – "Nutrien-standard"in diet therapy. Laboratory, functional and anthropometric parameters were monitored once a month. A significant increase in the physical development of patients was obtained only in the second year of use in the diet of supplementary nutrition, p<0.05. At the 3rd year of treatment, the results of positive dynamics of nutritional status in both groups were confirmed, while the increase in body mass index in the main group was 6.7%, and in the control group-only 1% (p<0.05). It is noted that the use of this mixture allows to achieve positive dynamics of nutritional status in 27% of patients and in 73% of cases to completely eliminate it. The obtained results prove the expediency of additional use of "Nutrient-standard" mixture in the complex therapy of patients with hereditary pancreatic enzyme deficiency, cystic fibrosis
The aim of this study was to evaluate, based on the analysis of neurobiochemical markers, the effectiveness of pathogenetically substantiated therapy for disorders of the psychomotor and physical development of children in the first year of life who underwent perinatal hypoxia. Materials and Methods:The study included 419 patients (52% boys and 48% girls) aged from 1 to 6 months. The main group included 336 patients in the first year of life who received inpatient treatment for perinatal CNS damage of different degrees of severity. The main group was divided into two subgroups according to age: Group 1 (n=163) between the ages of 1 and 3 months and Group 2 (n=173) between the ages of 4 and 6 months. In accordance with the severity of the CNS lesion, the main group was also divided into 3 subgroups: mild degree (n=122), moderate degree (n=118), and severe degree (n=96). The control group included 83 apparently healthy children (n=43 between the ages of 1 to 3 months and n=40 between the ages of 4 to 6 months). The analysis of individual physical development of the children was carried out using Z scores (weight, age, head circumference) and centiles (7 intervals ("corridors")) according to the WHO standard program WHO AnthroPlus, The concentrations of biochemical markers (L-Homocysteine, beta-NGF, S100 protein, angiotensin II) in the blood were evaluated in all children at admission, as a routine entry investigation. In accordance with a treatment regimen, the main group was also divided into 2 subgroups: subgroup A (n=170), patients who received therapy depending on a general clinical manifestation; and subgroup B (n=166), patients who received therapy depending on a dominant syndrome and variability of neurobiochemical markers.Results: We found that Scheme B showed advantages for all studied neurobiochemical markers, with statistical significance for L-Hcy regardless of the age group. The positive dynamics were found in the ND severity against the background of Scheme B regardless of the age group and the degree of severity of the CNS lesion. Thus, the pronounced positive dynamics in the levels of neurotrophic and neurovascular markers of the CNS lesion in all age groups reflects the advantage of pathogenetic therapy.

В статье впервые представляется клинико-генетическая характеристика мутации c.1083G>A (p.Trp361*) в гене CFTR. Патогенный генетический вариант c.1083G>A (p.Trp361*) гена CFTR относится к нонсенс-мутациям (I класс) и впервые был внесён в базу данных CFTR1 (http://www.genet.sickkids.on.ca) в середине 2019 г. без описания клинической картины муковисцидоза. Методы. Проведен анализ амбулаторных карт и историй болезни двух пациентов из неродственных семей с редким генетическим вариантом c.1083G>A (p.Trp361*). Для определения разности кишечных потенциалов (ОРКП) и проведения форсколинового теста на кишечных органоидах использовали биопсийный материал слизистой прямой кишки пациентов. ДНК для секвенирования выделяли из лейкоцитов венозной крови пациентов. Результаты. Анализ клинических проявлений заболевания у детей 6 и 9 лет показал наличие хронической панкреатической недостаточности, более выраженной у одного ребенка с синдромом дистальной интестинальной обструкции кишечника в анамнезе. Клиническая картина второго пациента характеризовалась развитием в раннем возрасте транзиторной гипербилирубинемии, синдрома псевдо-Барттера, а в дальнейшем - повторными эпизодами бронхиальной обструкции и развитием полипозного риносинусита. ОРКП и форсколиновый тест на кишечных органоидах показали, что генетический вариант c.1083G>A (p.Trp361*) относится к вариантам гена CFTR с отсутствием функции хлорного канала. Выводы. Впервые представлены описание клинической картины муковисцидоза у двух пациентов из неродственных семей с патогенным вариантом c.1083G>A (p.Trp361*) в компаунде с вариантом c.1521_1523delCTT (p.Phe508del) (ранее называемом F508del) и результаты оценки функции белка CFTR методом ОРКП и форсколиновым тестом на кишечных органоидах. In this article we continue to describe the pathogenic variants of the CFTR gene identified among Russian cystic fibrosis (CF) patients. For the first time the clinical and genetic characteristics of the mutation c.1083G> A (p.Trp361 *) are presented. The pathogenic genetic variant c.1083G> A (p.Trp361 *) of the CFTR gene belongs to the nonsense mutations (class I) and was listed for the first time in the CFTR1 database (http://www.genet.sickkids.on.ca) by Professor Milan Macek et al. in mid-2019 without any description of clinical manifestations of cystic fibrosis. Methods. The data of the National Register of Patients with Cystic Fibrosis of the Russian Federation 2017 were analyzed. Outpatient records and case histories of two patients from unrelated families carrying a rare genetic variant c.1083G> A (p.Trp361 *) were analyzed. To determine the Intestinal current measurement (ICM) and Forskolin-induced swelling (FIS) in intestinal organoids, rectal biopsy material of CF patients was used. DNA for sequencing was isolated from leukocytes of venous blood of the patients. Results. Variant c.1083G> A (p.Trp361 *) was found in two patients from unrelated families from different regions of the Russian Federation, according to the Register of Cystic Fibrosis Patients in the Russian Federation 2017. Analysis of clinical manifestations of the disease in children 6 and 9 years old showed the presence of chronic pancreatic insufficiency, more expressed in one child with a history of distal intestinal obstruction syndrome. The clinical manifestation of the second patient was characterized by the development of transient hyperbilirubinemia, Pseudo-Bartter’s syndrome at an early age, and subsequently repeated episodes of bronchial obstruction and the development of polypoid rhinosinusitis. The ICM method and the FIS in intestinal organoids showed that the genetic variant c.1083G> A (p.Trp361 *) refers to the variants of the CFTR gene with the absence of chlorine channel function. Conclusion. The clinical picture of cystic fibrosis in two patients from unrelated families with the pathogenic variant c.1083G> A (p.Trp361 *) in the compound with variant c.1521_1523delCTT (p.Phe508del) (variant legacy name F508del) and results of the evaluation of the CFTR protein functions, obtained by the method of ICM and using the FIS assay in intestinal organoids, are presented for the first time. Patients continue to be under the control in Russian CF centers.
