Muscle Infarction and Severe Deterioration of Renal Function in a Patient with Type 1 Diabetes Mellitus and Chronic Kidney DiseaseActa Endo (Buc) 2016 12(2): 224-226 doi: 10.4183/aeb.2016.224
AbstractContext. Spontaneous muscle infarction is a rare complication of diabetes mellitus, mainly affecting women and patients with long-lasting type 1 diabetes. Objective. This report is aimed to describe the case of a patient with type 1 diabetes and diabetic nephropathy in whom a severe deterioration of renal function was triggered by a muscle infarction. Subject and Methods. Subject of the study was a 33-years-old woman with an 18 years history of type 1 diabetes mellitus, proliferative diabetic retinopathy, nephropathy at stage 3 chronic kidney disease, somatic sensory-motor polyneuropathy and autonomic neuropathy. Results. The patient presented with severe pain and dysfunction of the left thigh without prior trauma plus progressive deterioration of the renal function. Nuclear magnetic resonance of the thigh showed inflammatory changes in the external vastus with hyperintensity on T2 sequence and edema of the subcutaneous cellular tissue. After other possible etiologies were ruled out, a clinical diagnosis of spontaneous muscle infarction was established. The patient needed hospital admission for two months, during which the renal function worsened until she required hemodialysis. No other possible triggers of kidney injury were identified. Conclusions. Up to our knowledge, this is the first described case where muscle infarction is suspected to have caused exacerbation of an existing chronic kidney failure. Monitoring the renal function should be considered in patients with diabetic nephropathy presenting with this rare complication of diabetes. -

Association of Ghrelin Receptor and Inflammation in Peri-Atrial Adipose Tissue from Obese Patients with Postoperative Atrial FibrillationActa Endo (Buc) 2020 16(3): 298-302 doi: 10.4183/aeb.2020.298
AbstractContext. Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice. The increasing evidence supports links between inflammation and AF. There is evidence showing that obesity is a major cause of adipose tissue (AT) inflammation. Ghrelin (GHRL), through its growth hormone secretagogue receptor (GHS-R) present on adipose tissue macrophages (ATMs), could modulate AT inflammation. Objective. Our study aimed to evaluate the role of adipose tissue macrophages (ATMs) and their GHS-R in adipose tissue samples of right atrial appendages (RAA) biopsies. Subjects and Method. We obtained RAA biopsies from 10 obese patients, undergoing cardiac surgery for coronary artery bypass graft (CABG) and developing postoperative atrial fibrillation (POAF). The epicardial tissue samples were examined using immunohistochemistry to visualize and quantify CD68 and GSH-R expression of the ATMs. Results. Histologically, the mean adipocyte diameter (MAD) of epicardial adipose tissue (EAT) was larger in EAT samples with inflammation as compared to EAT without inflammation (84.2 μm vs. 79.6 μm). The expression of CD68 was lower in EAT without inflammation as compared to EAT with inflammation in adipose tissue samples. Similarly, the expression of GSH-R was lower in EAT samples without inflammation as compared to EAT samples with inflammation in adipose tissue. Conclusions. Increased epicardial fat area, macrophage infiltration, and GHS-R expression in epicardial ATMs appeared to be associated with postoperative atrial fibrillation in obese patients. -

Pheochromocytoma, the Great Masquerader, Presenting as Reversible Cardiomyopathy: Primum Non NocereActa Endo (Buc) 2023 19(3): 370-375 doi: 10.4183/aeb.2023.370
AbstractBackground. Pheochromocytoma, the great masquerader, can have a varied spectrum of clinical manifestations. It can often cause a diagnostic challenge despite the availability of modern investigation modalities. Case. We present the case of a 38-year-old male who presented with uncontrolled hypertension for the past 10 years and heart failure for one year. The diagnosis of pheochromocytoma was missed in the initial setting, leading to a biopsy of the retroperitoneal mass. Fortunately, the patient survived the procedure. Subsequently, with the involvement of a multi-disciplinary team, he was optimized for surgery under strict cardiac monitoring. After the complete excision of the tumour, he showed significant improvement not only in his clinical symptoms but also in his cardiac status. Conclusions. This case emphasizes the age-old medical phrase of ‘Primum non nocere or first, do no harm’. Any invasive procedure in a pheochromocytoma can lead to a massive release of catecholamines causing a hypertensive crisis, pulmonary oedema, and even cardiac arrest. Any young patient presenting with hypertension or heart failure should be investigated for secondary causes. Cardiomyopathy due to pheochromocytoma is because of catecholamine overload and usually reverses or improves after curative surgery. -

Coronavirus as a Trigger of Graves’ DiseaseActa Endo (Buc) 2021 17(3): 413-415 doi: 10.4183/aeb.2021.413
AbstractContext. SARS-CoV-2 infection was declared a pandemic in 2020 and affected millions of people worldwide. Angiotensin-converting enzyme-2 receptors, through which coronavirus enters the cells of different organs, have been detected in the thyroid gland. The most common cause of thyrotoxicosis is Graves’ disease in which thyroid-receptors antibodies (TRAb) stimulate the TSH receptor, increasing thyroid hormone production and release. Case presentation. A 22-year-old woman had symptoms of palpitation, tremor, muscle weakness, anxiety and sleep disturbance. 3 weeks before the onset of these symptoms, the patient suffered from COVID-19, which lasted 14 days and was characterized by a course of moderate severity with fever up to 38˚C, general weakness without shortness of breath. The patient had no pre-existing thyroid problems. Her TSH was <0.01 mU/L, FT4, FT3 and TRAb were increased. Antithyroid drugs, glucocorticosteroids and β-blockers were prescribed. During 3 months of treatment doses of methimazole, methylprednisolone and bisoprolol were gradually reduced due to the improvement of the patient’s condition and thyroid tests normalization. Conclusions. COVID-19 infection can cause Graves’ disease and thyrotoxicosis. The onset of this disease after SARS-CoV-2 does not depend on the presence of preexisting thyroid pathology and requires the appointment of glucocortisteroids. -

NOS3 RS1799983 and RS2070744 Polymorphisms and their Association with Advanced Chronic Kidney Disease and Coronary Heart Disease in Canarian Population with Type 2 DiabetesActa Endo (Buc) 2021 17(4): 440-448 doi: 10.4183/aeb.2021.440
AbstractContext. Different polymorphisms of the endothelial nitric oxide synthase gene (NOS3) have been related to diabetic kidney disease. Objective. To evaluate the association between advanced diabetic chronic kidney disease (ACKD) and the rs1799983 and rs2070744 poymorphisms of NOS3 in a population from the Gran Canaria island. Design. Cross-sectional case-control study. Subjects and methods. Polymorphisms were genotyped in 152 subjects with ACKD secondary to type 2 diabetes [estimated glomerular filtration rate (eGFR) <30 mL/min/1.73 m2], 110 subjects with type 2 diabetes for 20 or more years since diagnosis without ACKD (eGFR ≥45 mL/ min/1.73m2 and albumin/creatinine ratio <300 mg/g and/or 24-h urinary albumin excretion <300 mg) and 292 healthy controls. Association between both polymorphisms and established coronary heart disease (CHD) was also analyzed in both groups with diabetes. Results. A greater proportion of homozygous individuals for the risk allele C of rs2070744 was found among subjects with ACKD. Association between ACKD and rs2070744 was observed in a recessive genetic model, both for comparison to subjects with diabetes but no ACKD [OR 2.17 (95% CI: 1.17-4.00), p=0.014] and for comparison to healthy controls [OR 1.61 (1.03-2.52), p=0.036]. The frequency of the C allele was significantly higher among subjects with CHD, but only in the group with ACKD. No associations were found for rs1799983. Conclusions. NOS3 rs2070744 is associated with ACKD in population with type 2 diabetes from Gran Canaria. A link between this genetic variant and CHD in Canarian subjects with type 2 diabetes could be restricted to cases with ACKD.
