Врожденный дискератоз (ВД) – наследственный синдром недостаточности костномозгового кроветворения, развивающийся вследствие нарушения биологии теломер и сочетающийся с предрасположенностью к опухолевым заболеваниям. Классическими клиническими признаками болезни («кожно-слизистая триада») являются ретикулярная пигментация кожи, дистрофические изменения ногтевых пластин, лейкоплакия слизистой оболочки полости рта. Цель – описать алгоритм диагностики, особенностей клинического течения и выбора терапии семейного случая ВД. Представлено клиническое наблюдение диагностики и лечения членов семьи с впервые выявленным ВД. Данное наблюдение демонстрирует важность всех этапов обследования: от сбора анамнеза и клинической картины до применения высокотехнологичных современных диагностических методов (flow-FISH, NGS). Подчеркивается, что при выявлении ВД у больного показано обследование членов семьи на наличие бессимптомного течения болезни. Высокая частота органной токсичности и развития вторичных неоплазий диктует необходимость индивидуального подхода к лечению каждого больного с этим заболеванием (раннее начало приема андрогенов, своевременное рассмотрение возможности выполнения трансплантации аллогенных гемопоэтических стволовых клеток).
Знание патогенеза, клинической картины, принципов диагностики и терапии этой нозологии актуальны как для врачей педиатрической практики, так и для гематологов.
Dyskeratosis congenita (DC) is a hereditary syndrome of bone marrow failure, which develops because of telomeres’ defects and combines with cancer predisposition. Its classical clinical features are skin pigmentation, nail dystrophy, oral leukoplakia (“skin-mucosa triad”). The goal is to describe the algorithm of diagnosis, clinical specificities of DC and specific treatment for cases of DC in one family. The present report includes descriptions of diagnosis and treatment of family members diagnosed for the first time as having a DC. The report shows an importance of all diagnostic stages: from a medical history and clinical picture to an application of modern high-tech diagnostic methods (flow-FISH, NGS). The report underlines an importance of diagnosis of all family members for excluding an asymptomatic form after a case of DC has been already detected in that family. A high frequency of a toxicity and secondary neoplasia makes it necessary to realize an individual approach at treatment of each patient with DC (the earliest start of androgen treatment, prompt decision of implementation of allogenic hematopoietic stem cell transplantation). The knowledge of pathogenesis, clinical features and principles of diagnosis and therapy of this disease is relevant to pediatricians and hematologists.
