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. -

Accuracy, Reproducibility and Reliability of Ultrasound Elastography versus Histopathology of Malignancy in Patients with Solid Thyroid NodulesActa Endo (Buc) 2014 10(3): 414-424 doi: 10.4183/aeb.2014.414
AbstractBackground. Thyroid nodules stiffness may predict thyroid malignancy. Objectives. The purpose of the study was to investigate the diagnostic value, interobserver agreement and reliability of real time ultrasound elastography (USE) when assessing solid thyroid nodules. Design. A prospective, observational study in a tertiary center. Subjects and Methods. In 49 patients scheduled for thyroidectomy, a senior radiologist and two radiologists in training independently assessed 81 solid thyroid nodules with USE using a 6600 Hitachi machine. Pathology results were used as a reference standard. Nodule stiffness was evaluated using the Asteria scoring system. The diagnostic ability of the elastography scores for the assessment of the thyroid solid nodules was evaluated using AUROC (area under the receiver operating characteristic curve) analysis. The Cohen’s kappa (k) values were used for interobserver agreement evaluation and interclass correlation coefficient (ICC) was used as a measure of reliability. Results. Pathology results revealed 20 papillary carcinomas and 61 benign nodules. The elastography identification of malignant nodules by the senior radiologist was performed with an AUROC of 0.84 [95% Confidence interval (CI) 0.74-0.91], with Sensitivity= 100%, and Specificity= 68.85%. When performed by ultrasound operators in training, the diagnostic performance slightly decreased. With no statistically significant difference between the diagnostic performance of the three readers, USE demonstrated good inter-observer agreement and good reliability (ICC= 0.81). Conclusion. USE may be an accurate tool of assessment for solid thyroid nodules, identifying with high sensitivity the malignant ones, particularly micronodules. USE is reproducible and reliable when used both by experienced operators and medical professionals in training. -

Prevalence of diabetic retinopathy in newly diagnosed type 2 diabetic patient in Isfahan, IranActa Endo (Buc) 2008 4(4): 415-423 doi: 10.4183/aeb.2008.415
AbstractBackground. Retinopathy is a common complication of diabetes and strongly related to the duration of the disease and the quality of its management. Despite this relationship, some studies have reported the prevalence of diabetic retinopathy at diagnosis to be 5-30%.\r\nAim. To investigate the prevalence of retinopathy in patients with newly diagnosed type 2 diabetes and its relation to some association factors in Isfahan, Iran.\r\nMethods. During 2001-2004, all newly diagnosed type 2 diabetics (n= 710) attending Isfahan Endocrine and Metabolism Research Center, were enrolled, by consecutive patient selection. Everybody accepted our invitation. The patients were examined by an internist and then by an ophthalmologist for retinopathy. Fasting plasma glucose, glycosylated hemoglobin, lipid profile, and 24-hour urinary albumin and creatinine concentrations were measured.\r\nResults. Of 710 patients, 286 were male. Mean age of the patients was 48.8(9.8) years (31-72 years) and median of diabetes duration was 6 months (0.5-12 months), respectively. Nine percent of patients (CI95%: 7-11) [(9.8% of men (CI95%: 6-13) and 8.5% of women (CI95%: 6-11)] had retinopathy (Odds ratio= 0.85, CI95%: 0.51-1.43, P= 0.5). In the final analysis using logistic regression test, body mass index (OR= 0.9, CI 95%: 0.8-1, P= 0.01), diastolic hypertension (OR= 3.9, CI 95%: 1.33-11.7, P= 0.01) and 24-hour urinary albumin concentration (OR= 1.005, CI 95%: 1-1.01, P= 0.01) were identified as association factors\r\nfor retinopathy.\r\nConclusions. Retinopathy was moderately prevalent in our patients. -

Myofibroblasts Hinder Recovery of Hashimoto Thyroiditis in the Ultrastructural LevelActa Endo (Buc) 2023 19(4): 415-420 doi: 10.4183/aeb.2023.415
AbstractBackground. Hashimoto thyroiditis (HT) is an autoimmune disorder associated with hypothyroidism. Lymphocyte infiltration leading to thyroid follicular cell destruction is counteracted by increased collagen production, deposition and scarring. However, only recently a specific subpopulation of modified fibroblasts with contractile properties, namely “myofibroblasts” (MFBs) have been linked to HT. Aim. Our ultrastructural study aims to delineate the presence and contribution of MFBs to the fibrotic milieu of HT. Material and Methods. Tissue biopsies were obtained from 5 HT-diagnosed patients and specimens were examined using a Transmission Electron Microscope (TEM). Results. Histopathological examination indicated extensive microvilli atrophy and atypical vacuolations of the thyroid follicular cells in the HT samples. In addition to interstitial extravasated lymphocytes, capillaries were encircled by MFBs (mean distance from lumen 1.248± 0.43μm) with the characteristic electron-dense α-smooth muscle actin (α-SMA), confirmable in higher magnifications. Myofibroblastic projections were found to have significantly higher representation near the capillary lumen compared to the impaired endothelial lining (P < 0.01). Conclusion. Our TEM findings suggest that the intrusion of endothelia by myofibroblastic projections can be a significant factor towards the malfunction of follicular cells in HT patients and offer a paradigmal understanding of the ultrastructural interactions that may underlie the HT pathology. -

The Potential of Diethylhexyl - Phthalate and Genistein to Induce Testicular Change in Rat's OffspringActa Endo (Buc) 2017 13(4): 417-424 doi: 10.4183/aeb.2017.417
AbstractObjective. To study the effect of diethylhexyl phthalate (DEHP) alone or in combination with genistein (GEN) on the reproductive system of offspring rats, focus on the induction of reproductive outcomes. Method. 180 Wistar rats were divided in 6 groups (30 animals per group): DEHP 250 mg/kg/day group, DEHP 1000 mg/kg/day group, DEHP 2500 mg/kg/day group treated with DEHP 2500 mg/kg/day, DEHP (2500 mg/kg) + GEN (50 mg/kg) group, DEHP (2500 mg/kg) + GEN (500 mg/kg) group and control group treated with the same quantity of corn oil. The differences in sperm quality and reproductive organs were observed. Results. After DEHP administration we observed an increase in rat’s abestrus, metaestrus and all estrus cycle (P < 0.05), a decrease in rat testicle’s organ coefficient and relative energy of testis Sertoli cells and an increase in the early, late and total apoptotic rate of testicular Sertoli cells in a dose dependent manner (P < 0.05). When combine DEHP with GEN the sperm density, sperm quality, the cell activity rate and testis tissue’s changes will decrease compared with the group that receive only DEHP in a dose dependent manner. Conclusion. DEHP exposure induces cryptorchidism in offspring rats and this is aggravated by adding GEN. -

Prevalence and Characteristics of the Polycystic Ovarian Syndrome in Overweight and Obese Premenopausal WomenActa Endo (Buc) 2022 18(4): 417-423 doi: 10.4183/aeb.2022.417
AbstractContext. Polycystic ovarian syndrome (PCOS) is commonly associated with obesity, but the prevalence of the syndrome in obese patients is not well established. Objective. The present study aims to investigate the prevalence of PCOS among overweight and obese premenopausal women and to evaluate the possible associations between the syndrome and metabolic disturbances in obese patients. Methods. Medical records of all women referred to a single endocrine center because of obesity and/or metabolic disturbances during a three-year period were analyzed. A total of 262 overweight and obese patients of reproductive age were included in the retrospective study. Results. The overall prevalence of PCOS using the Rotterdam criteria in the group of overweight and obese women was 26%. The degree of obesity did not influence the PCOS prevalence. Women with PCOS had higher blood glucose and insulin levels after glucose load in comparison to other obese patients despite the younger age. Conclusions. PCOS is a common finding among obese women seeking endocrine help. The oral glucose tolerance test is an important tool for the early detection of carbohydrate disorders in women with the syndrome. Furthermore, screening for PCOS components might be justified in young obese women with pronounced insulin resistance or dysglycemia. -

Central Macular Thickness in Diabetic Macular EdemaActa Endo (Buc) 2020 16(4): 417-425 doi: 10.4183/aeb.2020.417
AbstractContext. Retinal microvascular dysfunction differs in macular edema lesions in the two eyes of the same patient with diabetic retinopathy. Objective. To evaluate the relationship between central macular thickness (CMT) and metabolic/systemic factors including anthropometric and laboratory findings, in patients with regressed diabetic retinopathy and a history of pars plana vitrectomy (PPV) combined with internal limiting membrane peeling in one eye. Subjects and Methods. Forty-two eyes with PPV and the same patients’ fellow 42 eyes (without PPV) included this study. Fasting blood samples of these 42 diabetics were collected to study adiponectin levels and other routine parameters. Results. The average hemoglobinA1c value was 7.3±1.3%. CMT of the vitrectomized eyes were significantly correlated with atherogenic index of plasma, total cholesterol, low density lipoprotein cholesterol and uric acid (UA). On the other hand, CMT of the nonvitrectomized fellow eyes significantly correlated with glucose levels and diabetes duration. Adiponectin, adiponectin/body mass index, adiponectin/fibrinogen were found significantly higher in the subgroup with CMT≥300µm in the vitrectomized eyes (P<0.05). UA levels were higher in the subgroup with CMT≥300µm in the fellow (nonvitrectomized) eyes (P<0.05). Conclusions. Although there was no relationship between CMT and hemoglobinA1c values, CMT seemed to be affected by atherogenicity, prooxidant chemical alterations in the course of inflammation, so determination of adiponectin and UA levels may be suggested before surgery to predict the atherosclerotic damage and the postoperative CMT value. Vitrectomy performed at the proper time may be helpful in metabolic remodeling process of the retinal tissue along with life style changes, well control of diabetes, and intraocular treatments.
