Introduction: Nivolumab, an anti–programmed cell death-1 (PD-1) monoclonal antibody, is a promising treatment of variety advanced malignancies. Immune checkpoint inhibitors can cause immune-related adverse events, including endocrine pathology. Destructive thyroiditis is one of the most frequently observed nivolumab-induced endocrine irAEs which associated with the presence of anti–thyroid peroxidase antibodies (TPO-Abs) and anti-thyroglobulin antibodies (Tg-Abs) pri...

Backgraund: Insulinoma is the most common functional pancreatic neuroendocrine tumor originating from β-cells, with unregulated insulin production and rarely associated with MEN-I syndrome. Diagnosis and treatment of insulinoma are a challenge in the practice of endocrinologist.Aim: To determine on the basis of retrospective analysis the optimal approaches to the management of patients with organic hyperinsulinism.Materials an...

PurposePostoperative central diabetes insipidus (PCDI) is one of the complications of transsfenoidal adenomectomy (TSA) in patients with Cushing’s disease. Identification of predictors of PCDI development and clinical course could optimize the management of such patients.AimTo study the prevalence of PCDI in patients with Cushing’s disease after transsphenoidal adenomectomy and to find the risk fact...

Background Fibrocystic osteitis is rare PHPT manifestation. Poor management and delay in diagnosis of fibrocystic osteitis may lead to reduced quality of life and also provoke severe postoperative hypocalcemia – «hungry bone» syndrome.Clinical case We present a case of 66-years-old Caucasian woman, with history of urulithiasis/nephrocalcinosis (CKD stage 4), two pathological fractures, and fibrocystic osteitis. In Jan 2021...

Background: Detection of MRI-negative ACTH-producing pituitary adenomas is a challenge inthe management of patients with Cushing’s disease. There are some data on theability of pituitary adenomas to accumulate 18F-fluorodeoxyglucose during the 18F-FDG positron emission tomography and computer tomography (18F-FDG PET/CT). Aim: To study the potential of using a standardized uptake value (SUV) and a tumor &...

Background: Management of primary hyperparathyroidism (PHPT) in Multiple Endocrine Neoplasia type 1 syndrome (MEN 1) is still a challenge. PHPT developing in MEN 1 is characterized by the involvement of all parathyroid glands. Therefore, by modern guidelines, total or subtotal removal of the parathyroid glands is recommended. But this approach often leads to the development of hypoparathyroidism, adequate correction of which is not always possible. Drug therapy of recurrent PH...

Background: Detection of MRI-negative ACTH-producing pituitary adenomas is a challenge in the management of patients with Cushing’s disease. There are some data on the possibility of pituitary adenomas to accumulate 18F-fluorodeoxyglucose (18F-FDG) during the 18F-FDG positron emission tomography and computer tomography (18F-FDG PET/CT).Aim: To study the potential of brain 18F-fluorodeoxyglucose PET/CT for localization of MRI-negative ACTH-producing ...

Introduction: Perioperative assessment of surgical outcome in acromegaly patients is essential due to significant persistence rate even after total adenomectomy. Grade of adenoma invasiveness and basal growth hormone (GH) level in early postoperative period have been considered as important factors.Aim: The aim of our study was to evaluate the correlation between the outcomes of surgery in patients with acromegaly and the grade of adenoma invasion assess...

Purpose: According to modern guidelines late night serum cortisol measurement is not considered to be among the first steps for screening of hypercortisolism. But in some cases it may be useful as it allows identifying the loss of normal circadian rhythm of cortisol secretion. This test is not rarely used in hospitalized patients when Cushing’s syndrome is suspected. But the cutt-off point of nighttime serum cortisol level for the diagnosis of hypercortisolism is inconsis...

Introduction: Transsphenoidal surgery (TSS) is the treatment of choice for patients with acromegaly. However, even after radical surgery persistence of acromegaly may remain up to thirty percent by resent studies (Starnoni, 2016). Nadir growth hormone (GH) level less than 1.0 μg/l on an early postoperative oral glucose tolerance test (OGTT) have been suggested as early predictor of surgical remission (Kim 2012). However, the value of this approach remains to be defined.</...
