В последнее десятилетие наступила «новая эра» в лечении МВ, поскольку стали доступны препараты, восстанавливающие функцию CFTR хлорного канала, т. н. CFTRмодуляторы. Однако требуется дальнейшее изучение эффективности и безопасности таргетных препаратов дополнительными методами оценки.</p><p>Целью исследования явилось изучение роли метода определения разницы кишечных потенциалов (ОРКП) в оценке эффективности таргетной терапии МВ.</p><sec><title>Материалы и методы</title><p>Материалы и методы. У пациентов с МВ (n = 15: 10 детей, 5 взрослых) оценена эффективность терапии CFTR-модуляторами.  Согласно  клиническим  рекомендациям,  кроме  ОРКП,  оценивались  клинические  показатели,  потовая  проба и функция внешнего дыхания.</p></sec><sec><title>Результаты</title><p>Результаты. Восстановления функции хлорного канала у пациентов с генотипами 2143delT/712-1G&gt;T, G542X/R785X при терапии препаратом элексакафтор + тезакафтор + ивакафтор и лиц с генотипом L467F;F508del при терапии препаратом лумакафтор + ивакафтор не отмечено. У пациентов с генотипами F508del/F508del, N1303K/G461E, N1303K/3321delG отмечена положительная динамика в восстановлении функции канала CFTR при терапии препаратом элексакафтор + тезакафтор + ивакафтор, у пациентов с генотипом F508del/F508del – препаратами тезакафтор + ивакафтор и лумакафтор + ивакафтор.</p></sec><sec><title>Заключение</title><p>Заключение.

In the last decade, the treatment algorithm has entered a new era as several drugs have become available that restore the function of the CFTR chloride channel and are called CFTR modulators. The efficacy and safety of targeted drugs in cystic fibrosis needs to be further investigated using additional assessment methods.</p><p>The aim of this study was to investigate the role of intestinal current measurement (ICM) in assessing the efficacy of targeted therapy for cystic fibrosis.</p><sec><title>Methods</title><p>Methods. The efficacy of CFTR modulator therapy was evaluated in 15 patients, of which 10 were children and 5 were adults. In addition to the ICM method, patients’ clinical parameters, sweat test, and pulmonary function were also evaluated according to clinical guidelines.</p></sec><sec><title>Results</title><p>Results. Patients with genotypes 2143delT/7121G&gt;T and G542X/R785X had no restoration of chloride channel function with elexacaftor + tezacaftor + ivacaftor therapy, and patients with the L467F;F508del genotype with lumacaftor + ivacaftor therapy. In patients with the F508del/F508del, N1303K/G461E, N1303K/3321delG genotype, improvements were noted in terms of the restoration of CFTR channel function during therapy with elexacaftor + tezacaftor + ivacaftor therapy, and in patients with the F508del/F508del genotype during therapy with tezacaftor + ivacaftor therapy and lumacaftor + ivacaftor.</p></sec><sec><title>Conclusion</title><p>Conclusion. Restoring the function of the epithelial chloride channel (CFTR) is the basis for increasing life expectancy in CF. The crucial role of the ICM method in determining the efficacy of CFTR modulators is shown.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>муковисцидоз</kwd><kwd>метод определения разницы кишечных потенциалов</kwd><kwd>таргетная терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cystic fibrosis</kwd><kwd>method for intestinal current measurement</kwd><kwd>targeted therapy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации для Федерального государственного бюджетного научного учреждения «Медико-генетический научный центр имени академика Н.П.
