Обсуждается диагностический алгоритм при случайно выявленных образованиях надпочечников, направленный на определение гормональной активности и злокачественного потенциала, показания и ранжированность наблюдения для группы пациентов с гормонально неактивными доброкачественными опухолями. Рекомендовано определение гормональной активности образования, которая может проявляться гиперкатехоламинемией, эндогенным гиперкортицизмом, первичным гиперальдостеронизмом. Всем пациентам рекомендовано определение кортизола в утренние часы на фоне подавляющего теста с 1 мг дексаметазона. При отсутствии физиологического подавления уровня кортизола в качестве подтверждающего теста предлагается использовать определение адренокортикотропного гормона в утренние часы. В качестве метода первичной диагностики феохромоцитомы/параганглиомы (ФХЦ/ПГ) рекомендовано определение свободных метанефринов плазмы или фракционированных метанефринов суточной мочи. При положительном результате тестирования необходимо углубленное обследование для исключения или подтверждения ФХЦ/ПГ. При наличии у больного с опухолью надпочечника артериальной гипертензии рекомендовано определение соотношения между уровнем альдостерона и активностью ренина плазмы (прямой концентрации ренина) для исключения первичного гиперальдостеронизма. Для диагностики злокачественного потенциала опухоли рекомендована оценка количественных денситометрических показателей компьютерной томографии. Лечебная тактика в отношении инциденталом надпочечников не рассматривается в настоящих рекомендациях, так как является сферой компетенции соответствующих рекомендаций по конкретным нозологиям.
The autoimmune polyglandular syndrome of adults (APS) is characterized by the damage of two and more endocrine glands leading more often to development of their hormonal insufficiency. The basis of most autoimmune endocrine diseases is lymphoid and macrophage infiltration of the target organ. Often in patients with one autoimmune disease, other components of the APS appear after a some time of latent period. Besides defeat organs of endocrine system which are including to the APS also not endocrine organs can be part of autoimmune defeat. Although defeat of cardiovascular system is not included in the structure of the APS, in some clinical cases development of damage of a myocardium in the absence of clinically shown damage of heart against the background of the combined autoimmune endocrine pathology is described. The saved-up clinical this development of damage of a myocardium on the background of autoimmune endocrine insufficiency and also laboratory and instrumental methods of diagnostics is presented in the review at this state. The most promising diagnostic methods for this condition are the determination of autoantibodies to myocardial components and magnetic resonance imaging of the heart. In clinical practice, it is possible to widely use the definition of antibodies to myocardium by indirect immunofluorescence, as well as using standardized immunoenzyme test systems.The saved-up clinical this development of damage of a myocardium on the background of autoimmune endocrine insufficiency and also laboratory and instrumental methods of diagnostics is presented in the review at this state.
This lecture focuses on the diagnosis and differential diagnosis of adrenal incidentalomas with special reference to diagnostic steps, major pharmacological tests, and instrumental studies. Strategies of management of patients with this pathology are described.
In the article there are presented main approaches to the diagnosis, treatment and follow-up of patients with classical and nonclassical forms of 21-hydroxylase deficiency. The techniques of diagnostic tests and parameters of hormonal indices for the assessment of the adequacy of replacement therapy with glucocorticoids and mineralocorticoids are considered.
Primary hyperaldosteronism (PA) - is the clinical syndrome, results from autonomous of the major regulators of secretion, aldosterone overproduction by a tumorous or hyperplastic tissue in adrenal cortex. Being the most frequent cause of secondary hypertension, PA may be represented by disorders with unilateral or bilateral aldosterone overproduction and differential diagnosis between them is crucial for choosing a right therapeutic approache: lifelong medical therapy with mineralocorticoid receptor antagonists or unilateral adrenalectomy. Adrenal venous sampling (AVS) is currently the «gold standard» test for identifying laterality of excess hormone production, unlike imaging tests, sensitivity and specificity of which is not enough, due to inability to evaluate functional activity with confidence, and also to limitations in detecting tiny abnormalities of adrenals, such as microadenoma or hyperplasia. Excluding certain cases, AVS is recommended to patients with confirmed PA, planning surgical treatment, to determine the lateralization of aldosterone hypersecretion. Described clinical case of patient with confirmed lateralization from adrenal without any detected lesions on CT-imaging and nonfunctioning tumour on contralateral side, highlights the importance of using AVS for decision to refer patients for surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
