Introduction: The genetic causes of development of multiple endocrine neoplasia type 1 (MEN-1) phenocopies remain largely unknown.Aim of the study: To evaluate the role of genes associated with familial primary hyperparathyroidism (PHPT) in the development of MEN-1 phenocopies with the combination of PHPT and pituitary adenomas (PA).Materials and methods: 20 patients (19 females and 1 male) were included in the study. All patients ...

The levels of decorin in patients with Cushing’s disease and acromegaly

Tsoriev Timur , Belaya Zhanna , Rozhinskaya Lyudmila , Ilyin Alexandr , Nikankina Larisa , Mel'nichenko Galina , Dedov Ivan

Decorin is myokine expressed and released in response to muscle contractions. It induces growth and hypertrophy of skeletal muscles in different ways including myostatin inhibition. It is still not clear whether decorin takes part in development of muscle atrophy in endocrine pathologies.Objective: To evaluate decorin levels in patients with endogenous hypercortisolism and GH oversecretion.Materials and methods: Three groups were i...

Russian hypothalamic and pituitary tumors registry (OGGO) data analysis: acromegaly

Lutsenko Alexander , Przhiyalkovskaya Elena , Pigarova Ekaterina , Belaya Zhanna , Rozhinskaya Liudmila , Stanoevich Irina

Objective: To analyze registry data on patients with acromegaly.Materials and methods: Russian hypothalamic and pituitary tumors registry database (on-line platform), which contains data on 3719 patients with acromegaly.Results: According to the database, highest prevalence of acromegaly per 100 000 inhabitants is registered in: Penza region (7.3), Kirov region (7.3), Krasnoyarsk region (6.2). Most common clinical presentations in ...

Immunohistochemical characteristics of blood vessels in non-visualized and visualized on MRI pituitary adenomas in patients with Cushing’s disease (pilot study)

Voronkova Iya , Belaya Zhanna , Khandaeva Patimat , Rozhinskaya Liudmila , Vorontsov Alexander , Sitkin Ivan , Grigoriev Andrey , Melnichenko Galina

Introduction: Regardless of improvements in MRI, up to 20% of ACTH-secreting pituitary tumors are only identified at surgical exploration. The objective was to estimate whether there is any difference in blood vessels and the subsequent ability to uptake contrast agent in visualized micro-adenomas as compared to non-visualized on MRI ACTH-secreting pituitary tumors.Materials and methods: Retrospective evaluation of ACTH-positive pituitary tumors from pat...

Vertebral and non-vertebral low-traumatic fractures in patients with type 2 diabetes mellitus

Yalochkina Tatiana , Belaya Zhanna , Rozhinskaya Liudmila , Antciferov Michail , Dzeranova Larisa , Shestakova Marina , Melnichenko Galina

Introduction: Recent evidence suggests that the skeleton might be another affected organ in patients with type 2 diabetes mellitus (T2DM). This study evaluates the prevalence of low-traumatic vertebral and non-vertebral fractures and their risk factors in subjects with T2DM.Materials and methods: We invited outpatients with T2DM, who were under observation in a single outpatient clinic. The subjects were interviewed regarding the presence of low-traumati...

Clinical presentations of patients receiving PTH-therapy among the referral population with hypoparathyroidism.

Gronskaia Sofia , Grebennikova Tatiana , Pigarova Ekaterina , Rozhinskaya Luidmila , Melnichenko Galina , Luiza Brandi Maria , Belaya Zhanna

This study aims to evaluate patients who require PTH-treatment among the referral population with hypoparathyroidism.Methods: The information was collected from the registry database of chronic hypoparathyroidism, which was initiated by the National Medical Research Centre for Endocrinology (NMRCE).Results: Among 194 cases of hypoparathyroidism referred to our clinic over 2 years (2017–2019), eig...

Osteogenesis imperfecta type V due to a rare mutation c.119C> T in the IFITM5: A case report

Grebennikova Tatiana , Gavrilova Alina , Tiulpakov Anatoly , Tarbaeva Natalia , Melnichenko Galina , Belaya Zhanna

Osteogenesis imperfecta (OI) is a heritable skeletal disorder caused by defective bone formation. OI type V (MIM#:614757) develops due to mutation in the IFITM. Mutation c.-14C >T in the IFITM5 is more common whereas only five reported patientshave a c.119C >T mutation. Patients with IFITM5:c.119C >T mutation usually have low-traumatic fractures in the prenatal period of development, severe limb and chest deformities, short height, verteb...

Plasma microRNA levels in patients with active acromegaly

Lutsenko Alexander , Belaya Zhanna , Nikitin Alexey , Solodovnikov Alexander , Lapshina Anastasia , Przhiyalkovskaya Elena , Melnichenko Galina

Background: Plasma microRNAs (miRs) (miR-4446-3p, miR-215-5p, miR-342-5p) were downregulated in patients with active acromegaly (AM) compared with healthy control subjects as assessed by next-generation sequencing.Aim: The aim of this study wasto validate the previously observed finding in the newly enrolled patients with AM using qRT-PCR.Materials and methods: Morning plasma samples were collected from fasting patients with AM and...

Difference in plasma miRNA levels in inferior petrosal sinus samples from patients with ACTH-dependent Cushing’s syndrome as assessed by next-generation sequencing (NGS).

Belaya Zhanna , Malygina Anastasia , Nikitin Alexey , Koshkin Philipp , Sitkin Ivan , Rozhinskaya Liudmila , Melnichenko Galina , Dedov Ivan

Introduction: ACTH-secreting pituitary adenoma tissue differs from normal pituitary gland tissue in microRNA (miR) expression. MiRs are secreted into circulation and can be detected as potential biomarkersAim: To evaluate the difference in miR levels in plasma samples drained from inferior petrosal sinuses in patients with Cushing’s disease (CD) and ectopic-ACTH syndrome (EAS).Materials and methods: we enrolled 24 patients wi...
