Prediction of the receptor phenotype of somatotrophic tumors and the effectiveness of the use of the first-generation somatostatin receptor ligands (fg-SRLs) in the long-term treatment of acromegaly

Pronin Evgeny , Antsiferov Mikhail , Alekseeva Tatiana , Lapshina Anastasia , Pronin Vyacheslav

The control of acromegaly with drug therapy (DT) by fg-SRLs is achieved only in 40–50% of cases, due to the heterogeneous composition of somatotrophic tumors. In order to optimize DT stratification of clinical and immunophenotypic biomarkers which make it possible to predict the long-term effectiveness of fg-SRLs at early stages is required. The aim of the work was to assess the informativeness of pharmacotherapeutic testing (% of decrease of IGF-1 level after 3 and 6 mon...

Treatment of Cushing’s disease by transsphenoidal pituitary microsurgery: prognosis factors and long-term follow-up

Arapova Svetlana , Marova Evgeniy , Kolesnikova Galina , Grigorev Andrey , Lapshina Anastasia

In our study we included retrospective analyses of 101 patients (mean age 35 years, 85 women and 16 men) with Cushing’s disease (CD), who underwent transsphenoidal surgery (TSS) treatment. CD is based on clinical suspicion, hormonal research of cortisol (F), ACTH, 24-hous urine F, results of dexamethasone suppression tests low (1 mg) dose (LDDST) and high (8 mg) dose (HDDST) and MR-imaging (MRI). Before the operation all patients have high F, ACTH, negative LDDST and posi...

Hormonal characteristics of recurrent ACTH-secreting pituitary adenomas

Marova Evgenia , Arapova Svetlana , Lapshina Anastasia , Kolesnikova Galina , Grigoriev Andrey , Voroncov Alexsandor

Cushing’s disease (CD) remission after primary surgical treatment is achieved in 70–90%, but recurrence ranges 18–25% after.The aim of this work was to study clinical, hormonal and MRI indicators before and after surgical treatment in patients with recurrent CD to identify possible predictors of recurrence. We examined 49 patients with recurrent CD in the active stage (disease duration up to 3 years). Before neurosurgery blood ACTH (median...

Phaeochromocytomas are responsible for the development ACTH-ectopic syndrome in 5% cases. Less than 1% phaeochromocytoma accompanied by symptoms of ACTH-dependent hypercortisolism. We observed four cases of ACTH-secreting phaeochromocytoma during 2 years. All patients were women from 50 to 63 years. The disease duration ranged from 6 months to 5 years. The clinical picture presented the signs of hypercortisolism (matronism, hyperpigmentation of the skin, the redistribution of ...

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...

Clinical features, diagnostic criteria and treatment outcomes in 40 patients with thyrotropin-secreting pituitary tumors

Dimitrova Diana , Przhiyalkovskaya Elena , Grigoriev Andrey , Azizyan Vilen , Lapshina Anastasia , Belaya Zhanna , Melnichenko Galina

IntroductionThyrotropin-secreting pituitary adenomas (TSH-omas) are rare. For this reason each case of TSH-secreting pituitary tumor can help expand extensive clinical experience in world practice.Materials and methodsWe included 40 patients with TSH secreting pituitary adenomas. Hormonal profile: TSH (0.25-3.5 mIU/L), FT4 (9-20 pmol/l) FT3 (2.5-5.5 pmol/l) were measured by Architect i2000SR (Abbott Laborator...

Pituitary adenomas characteristics in patients with multiple endocrine neoplasia type 1, its phenocopies and sporadic acromegaly

Trukhina Diana , Mamedova Elizaveta , Lapshina Anastasia , Nikitin Alexey , Koshkin Philipp , Azizyan Vilen , Grigoriev Andrey , Belaya Zhanna , Melnichenko Galina

Multiple endocrine neoplasia type 1(MEN1) is a hereditary condition caused by mutations in the MEN1 gene, which encodes menin protein. The syndrome predisposes to the development of tumors in both endocrine and non-endocrine systems. In patients with MEN1, pituitary adenomas (PA) occur in approximately 40% of all cases. If patient has MEN1 phenotype with no mutations in MEN1 gene, the condition is regarded as a phenocopy. The reason of several endocrine MEN1-...

Introduction: Recent studies have shown that microRNA could serve as biomarkers in various types of cancer and other diseases. Aim: To reveal microRNA that differ in patients with Cushing’s diseases (CD) and Ectopic ACTH-syndrome (EAS) to form a specific panel for differential diagnosis of ACTH-dependent Cushing’s syndrome (CS).Materials and Methods: Plasma samples from both sinuses and cubital vein were drained during in...
