Objective To analyze the clinical presentations of patients with endogenous Cushing’s syndrome (CS) affected by Coronavirus disease-19 (COVID-19). Materials and methods Patients who were referred to our clinic with active CS from 31st March to 15th May 2020 were screened for COVID-19 using real-time reverse transcriptase–polymerase chain reaction (RT-PCR). Late-night serum cortisol (64–327 nmol/L), late-night salivary cortisol (LNSC) (0.5–9.4 nmol/L), or 24-h urinary free cortisol (24 hUFC) (100–379 nmol/24 h) were measured by electrochemiluminescence immunoassay. Results Among 22 patients with active CS we found three cases affected by COVID-19. Nonspecific inflammation markers were within the reference range or slightly elevated in these patients. A 71-year-old woman with newly diagnosed CS (late-night serum cortisol >1750 nmol/L, LNSC 908.6 nmol/L) developed dyspnea as an only symptom and died from bilateral polysegmantal hemorrhagic pneumonia 7 days later. A 38-year-old woman with a 5-year medical history of active Cushing’s disease (CD) (late-night serum cortisol 581.3 nmol/L, 24 hUFC 959.7 nmol/24-h) suffered from dyspnea, cough, fever (39.3 °C) and chest pain. Oxygen therapy, antibiotics and symptomatic treatments lead to full recovery 24 days later. A 66-year-old woman with a 4-year medical history of mild CD (late-night serum cortisol 603.4 nmol/L, LNSC 10.03 nmol/L) tested positive for COVID-19 in routine screening and remained asymptomatic. Conclusions The outcome of COVID-19 in patients with CS depends on the severity of hypercortisolism. Thus, severe hypercortisolism is a warning sign that CS affected by COVID-19 could require emergency care despite a lack of clinical presentations and low inflammation biomarkers.

Due to continuous aging of population and increase in the number of elderly people, osteoporosis became socially significant disease leading to disability, increasing mortality and thereby putting an additional burden on the public healthcare system.Screening to identify groups with a high probability of fracture is recommended using the FRAX® Tool for all postmenopausal women and men over 50 years old (А1). In the presense of major pathological fractures (hip, spine, multiple fractures) it is recommended to diagnose osteoporosis and prescribe treatment regardless of the results of spine and hip double X-ray absorptiometry (DXA) or FRAX® (B2).It is recommended to evaluate C-terminal telopeptide when prescribing antiresorptive therapy and procollagen type 1 N-terminal propeptide (P1NP) when prescribing anabolic therapy to patients receiving osteoporosis treatment at baseline and 3 months after the start of therapy in order to assess the effectiveness of treatment early and adherence to the therapy (А2). It is recommended to diagnose osteoporosis and prescribe treatment to patients with high individual 10-year probability of major pathological fractures (FRAX®) regardless of the results of spine and hip DXA (В3).It is recommended to diagnose osteoporosis and prescribe treatment with a decrease in BMD, measured by DXA, by 2.5 or more T-score standard deviations in femoral neck, and/or in total hip, and/or in lumbar vertebrae, in postmenopausal women and men over 50 years old (А2).It is recommended to prescribe bisphosphonates, denosumab or teriparatide to prevent pathological fractures and increase BMD in patients with postmenopausal osteoporosis, osteoporosis in men, glucocorticoid-induced osteoporosis (А2). When the clinical effect of therapy in osteoporotic patients without pathological fractures is achieved (BMD T-score > -2.0 SD in femoral neck and absence of new fractures), it is recommended to interrupt bisphosphonates therapy for 1-2 years with subsequent follow-up (B2). In patients with vertebral fractures, hip fractures or multiple fractures, it is recommended to continue ceaseless long-term treatment of osteoporosis (В3).All drugs for the treatment of osteoporosis are recommended to be prescribed in combination with calcium and cholecalciferol (А2). In order to reduce the risk of recurrent fractures by prescribing osteoporosis therapy timely and maintaining long-term follow-up of patients over 50 years old with pathological fractures, it is recommended to create Fracture Liaison Services (В2).

Cardiovascular complications including arrhythmias and cardiac conduction disorders are one of the main reasons of high mortality rate in acromegaly, while they have not been well explored. Aim.To estimate arrhythmias frequency in acromegaly, identify risk factors leading to the development of arrhythmia and cardiac conduction disorder, to determine the role of cardiac MRI in detecting structural and functional changes. Materials and methods.A single-center prospective cohort study, which included 461 patients (151 men and 310 women) with acromegaly, was conducted. All the patients underwent a standard medical examination, including hormonal blood test, electrocardiogram, echocardiography, electrocardiogram daily monitoring. 18 patients with arrhythmias (11 men and 7 women) had cardiac MRI with gadolinium-based contrast. Results.The results of our research show high frequency of arrhythmias and cardiac conduction disorders in patients with acromegaly 42%. Most frequent kinds of arrhythmias and cardiac conduction disorders were sinus bradycardia 19.1% of the cases and conduction disorders of bundle branch blocks 14.5%. Men were more likely to suffer from arrhythmias and cardiac conduction disorders than women (54.2% and 37.4%, respectively,p=0.0005). Not acromegaly activity but duration of the disease was a main risk factor of arrhythmias and cardiac conduction disorders. Patients with arrhythmias had a long anamnesis of acromegaly (10 and 7 years, respectively, p=0.04). Meanwhile, cardiac conduction disorders were commonly observed in the patients who were treated with somatostatin analogs comparing to the patients who didnt undergo this therapy (50% and 38.6% respectively,p=0.004). We showed that 61% of patients with acromegaly and cardiac conduction disorders who underwent magnetic resonance imaging (MRI) had the signs of myocardial fibrosis. The value of the ejection fraction of the left ventricle according to MRI was higher than with echocardiography (p=0.04). Conclusion.Arrhythmias and cardiac conduction disorders are often observed in patients with acromegaly even with remission of the disease. High risk group need careful diagnostic and monitoring approaches. Cardiac MRI is the gold standard for visualization of structural and morphological changes in the heart. Use of cardiac MRI in acromegalic patients expands our understanding of arrhythmias and cardiac conduction disorders in this disease. There are no specific laboratory markers of diffuse myocardial fibrosis, and the role of myocardial fibrosis in the occurrence of cardiac arrhythmias and conduction disorders needs further studying.
