    Serum Vitamin D Levels in Different Morphologic Forms of Age Related Cataract

    Acta Endo (Buc) 2020 16(2): 178-182 doi: 10.4183/aeb.2020.178

    Purpose. Vitamin D insufficiency and age related cataract (ARC) are public health problems. We evaluated serum vitamin D levels in ARC patients. Method. A prospective hospital-based crosssectional study was designed to measure the vitamin D status of patients with ARC. Patients have grouped either presence of any type of posterior subcapsular cataract (PSC) (group 1) or ARC without the PSC component (Group 2). After full ophthalmologic consideration, patients over 40 years of age with no history of ocular trauma, multivitamin supplement ingestion, chronic renal failure, thyroidectomy, parathyroidectomy, skin cancer, and cigarette smoking were included in the study. Results. Totally, 79 subjects of which 26 (32.9%) subjects in group 1 and 53 (67.1%) subjects in group 2 were included in the study. Group 1 had mean vitamin D levels of 17.31±13.30 ng/mL. Vitamin D levels in Group 2 were 13.34±7.87 ng/mL. Group 1 did not show vitamin D insufficiency (P = 0.31; one-sample t-test). However, Group 2 showed a statistically significantly lower vitamin D level compared to the insufficiency level of 20ng/mL (P= 0.00; one-sample t-test). Conclusion. Vitamin D may have an important function in lens metabolism. Vitamin D deficiency and cataract development need further extensive researches.

    A Patient with an Atypic Neck Mass Lesion

    Acta Endo (Buc) 2020 16(2): 232-235 doi: 10.4183/aeb.2020.232

    An 81-year-old woman presented with a history of essential hypertension for eight years and an asymptomatic multinodular goiter that had been incidentally discovered on neck ultrasonography two years ago and an-isohypoechoic mass lesion located adjacent to the right lobe inferior pole of the thyroid gland. Parathyroid adenoma or lymphadenopathy were the differential diagnosis. After two years, the endocrine surgeon decided to operate her multinodular goiter and her probably benign lesion. Intraoperatively, the blood pressure and pulse rate increased markedly and intravenous antihypertensive treatment was administered. She was discharged after blood pressure control. A 2 mm micromedullary thyroid carcinoma with C-cell hyperplasia located on the left lobe of the thyroid was detected. The aforementioned mass lesion was also reported as typical cervical paraganglioma. Because of concomitant medullary thyroid carcinoma with C-cell hyperplasia and paraganglioma the patient was subjected to genetic counseling and molecular testing for hereditary cancer syndromes. A variation of the succinate dehydrogenase gene D (SDHD) NM_003002.3: c.325C> T (Gln109Term) has been reported as the disease-causing mutation. Herein we present a case diagnosed for neck paraganglioma and medullary thyroid carcinoma after an intraoperative hypertensive crisis.

    Recombinant Human Thyrotropin Versus Thyroid Hormone Withdrawal in Differentiated Thyroid Carcinoma Follow-Up: a Single Center Experience

    Acta Endo (Buc) 2021 17(3): 337-345 doi: 10.4183/aeb.2021.337

    Introduction. Our goal was to evaluate and compare the diagnostic utility of thyroid hormone withdrawal (THW) and recombinant thyroid-stimulating hormone (rhTSH) methods in detecting recurrence/persistence (R/PD) of differentiated thyroid carcinoma (DTC). Methods. The study included 413 patients with DTC who underwent total thyroidectomy and had remnant ablation. DxWBS, s-Tg levels, R/PD were evaluated retrospectively. A s-Tg level≥2 ng/mL was considered as “positive s-Tg”. Results. DxWBS and s-Tg levels were evaluated with rhTSH in 116 and THW in 297 subjects, respectively. The sensitivity and specificity of “positive s-Tg” for R/PD in THW group were 77.3% and 92.7%, with 90.3% accuracy, respectively. The sensitivity and specificity of “positive s-Tg” for R/PD in rhTSH group were 58.8% and 100% with 93.9 % accuracy, respectively. An uptake outside thyroid bed at WBS showed a sensitivity of 17.1%, specificity of 100% for R/PD with 89.4% accuracy in THW group. An uptake outside thyroid bed at WBS showed a sensitivity of 7.7%, specificity of 100% for R/PD with 88.8% accuracy in rhTSH group. Conclusion. Method of TSH stimulation did not influence the reliability of DxWBS. The “positive s-Tg level” had a higher sensitivity with THW when compared to rhTSH in detecting R/PD.

    Thyrotoxic, hypokalemic periodic paralysis in a Turkish man: a case report

    Acta Endo (Buc) 2007 3(3): 345-349 doi: 10.4183/aeb.2007.345

    Thyrotoxic hypokalemic periodic paralysis (TPP) is a disorder leading to hypokalemia and muscle weakness. It mainly affects the Asian population, and it is rare in the Balkan and Caucasian people. We describe a case of a 34 year-old male presenting with TPP. To our knowledge, this case is the third Turkish patient diagnosed as TPP in the English medical literature. He was admitted to the Emergency Department (ED) with generalized weakness. Initial laboratory analysis showed that serum potassium was 1.6 mmol/L. His serum potassium was normalized after intravenous administration of potassium chloride (KCl) of 80 mmol over 4 h and 40 mg of propranolol administered orally, and then his generalized weakness was recovered. Thyrotoxicosis was treated with propylthiouracil and propranolol.

    Levels of Adinopectin, TNF-a, and Vascular Cell Adhesion Molecule in the Obese Women with Metabolic Syndrome

    Acta Endo (Buc) 2007 3(4): 405-416 doi: 10.4183/aeb.2007.405

    Adipocytokines involved in inflammation and the acute phase responders have been found to be increased in the metabolic syndrome (MS). The aim of the study was to compare the ‘normal’ weight women’s fibrinogen, hsCRP, adiponectin, TNF-α, vascular cell adhesion molecule (VCAM) with obese patients with MS, and to evaluate the association between fibrinogen, hsCRP, adiponectin, TNF-α, VCAM and insulin resistance. The study included 52 obese women who met the criteria for MS defined as in 2001, the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) ATP III and 24 normal women. Serum concentrations of glucose (FBG), triglyceride, total and HDL-Cholesterol were determined by enzymatic procedures, serum insulin was measured by chemiluminescence, plasma levels of adiponectin, TNF-α and VCAM by Elisa, hsCRP by immunoturbimetric assay and fibrinogen by coagulation method. Measurements of insulin resistance were obtained using the homeostasis model assessment. Mean plasma levels of adiponectin, TNF-α, VCAM, fibrinogen and hsCRP were found 6.11±2.39 mg/ml, 3.10±3.30 pg/ml, 14.21±4.00 ng/ml, 375.49±49.67 mg/dl, 0.33±0.10 mg/dl in the obese with MS; 6.20±2.48 mg/ml, 3.01±1.68 pg/ml, 12.63±2.54 ng/ml, 304.06±49.52 mg/dl, 0.30±0.19 mg/dl in the normal women, respectively. Mean fasting insulin level and HOMA-IR were measured 13.80±6.32 mU/ml and 3.69±1.90 mU/ml, respectively in obese with MS. In normal women, fasting insulin level and HOMA-IR were measured 8.30±3.08 mU/ml and 1.49±0.37, respectively. Mean levels of adiponectin were positively correlated with mean TNF-α levels in the obese with MS (r=0.472, p=0.001). VCAM was negatively correlated with TNF-α levels (r=-0.301, p=0.038) in the obese with MS. This study demonstrated that TNF-α showed a positive association with adiponectin and a negative association with VCAM in the obese women with MS.

    The Course of Autoimmune Thyroiditis in Women

    Acta Endo (Buc) 2021 17(4): 472-478 doi: 10.4183/aeb.2021.472

    Context. Although, many studies have been made on the clinical course of autoimmune thyroiditis, this study focused on women and the factors effecting the natural course such as Selenium. Objective. The study aimed to determine Hashimoto’s thyroiditis (HT) clinical course in adults and the factors that could affect it. Design. The study was in a retrospective manner between 2010-2018. Subjects and Methods. 101 patients with HT were followed for 60.7±32.7 months. Biochemical and ultrasonographic data were collected. We investigated whether the age at diagnosis, family history, smoking habits, levothyroxine replacement therapy, and serum selenium (Se) levels influenced the disease course. Results. No relationship was observed between age and thyroid functions, thyroid volumes (TV), and autoantibody (Ab) levels at diagnosis. Ab levels were irrelevant with TV, echogenicity, and nodularity at diagnosis. However, initial TSH levels were significantly associated with anti-TPO levels (p=0.028, r=0.218). In the untreated group, thyroid functions seemed to be stable. TV decreased significantly in both treated and untreated patients (p<0.001). The decrease in TV was significantly higher in the treatment group (p=0.002). In euthyroid and subclinical hypothyroid patients, levothyroxine therapy did not affect the decrease in TV. Ab levels remained stable in untreated patients, but anti-TPO levels significantly decreased in treated patients (p<0.001). Smoking seemed to increase only anti-Tg levels (p=0.009). Family history was not associated with any of the studied parameters. Serum Se level was negatively correlated only with thyroid echostructure and only in treated patients. TV showed a “Gaussian distribution” in all patients at the diagnosis and at the end, independent of levothyroxine treatment. Conclusions. Most euthyroid patients remained euthyroid during five years of follow-up. The decrease in TV was significantly prominent with LT4 treatment. Importantly, TV followed a normal distribution instead of the bimodal distribution that is classically described.
