    Serum Omentin-1 Levels and Endothelial Dysfunction in Obesity

    Acta Endo (Buc) 2017 13(2): 138-143 doi: 10.4183/aeb.2017.138

    Abstract
    Introduction. Our aim was to investigate the relationship between serum omentin-1 levels and endothelial dysfunction in obese patients. Material and Methods. We evaluated 50 obese patients, and age/gender matched 45 healthy non-obese subjects as controls. Oral glucose tolerance test, lipid parameters, uric acid levels, homeostatic model assessmentinsulin resistance (HOMA-IR) index, serum omentin-1 levels and flow mediated dilatation (FMD) % were measured in all subjects. Body compositions were analyzed with bioelectrical impedance method using a Tanita Body Composition Analyzer and ViScan. Results. Serum omentin–1 levels were found significantly lower in obese population compared to the control subjects. FMD response was significantly decreased in obese population. There was a significant positive correlation between serum omentin–1 levels and FMD response (r=0.359, p<0.001). Serum omentin–1 levels were negatively correlated with body mass index (BMI), waist circumference, total fat percentage, visceral fat, fasting insulin and HOMA-IR index. Conclusion. Lower serum omentin–1 levels and decreased FMD response may be an early marker of endothelial dysfunction in obese patients.

    A Rare Cause of Discordant TSH: MACRO-TSH

    Acta Endo (Buc) 2015 11(2): 170-173 doi: 10.4183/aeb.2015.170

    Abstract
    When the laboratory results are not compatible with the clinical features of the patient, the presence of assay interference should be considered. Patient and Methods. Here, we report a case of macro-thyroid stimulating hormone (macro-TSH) in a 31 yearold woman who had hypothyroidism due to thyroidectomy as well as discordant TSH levels with the clinical findings. Her TSH level was spuriously high with low levels of free T3 and T4 on levothyroxine treatment and she had only mild fatigue. To screen for the presence of interference, we performed TSH measurements in different platforms and serial dilution of the sample. Her rheumatoid factor was found to be negative. Results. The testing for heterophile blocking and non-specific anti TSH antibodies suggested lack of interference. We did further test for the clinical suspicion of interference and TSH decreased to 29.8 μIU/mL from 210.5 μIU/mL (recovery: 14.1%) after polyethylene glycol (PEG) precipitation indicating the existence of macro-TSH. After two months of increased dosage of levothyroxine, her TSH level was still very high (192.0 μIU/mL), but free T3 and free T4 increased to normal levels. PEG precipitation test was reperformed and TSH was decreased to 46.0 μIU/mL from 192.0 μIU/mL (recovery: 24.0 %). Her levothyroxine replacement dosage was not increased since free T3 and T4 levels were normal. Conclusions. If there is a suspicion for the discordant TSH level, the presence of macro-TSH by PEG precipitation should be investigated even though first step investigations for interference were found to be negative.

    The Evaluation of Short and Long-Term Quality of Life in Patients Undergoing Thyroidectomy Due to Benign or Malignant Diseases

    Acta Endo (Buc) 2024 20(2): 170-178 doi: 10.4183/aeb.2024.170

    Abstract
    Context. In patients undergoing thyroidectomy for malignant disease, lower quality of life scores were observed in the early postoperative period compared to those undergoing thyroidectomy for benign causes. Objective. Thyroid gland diseases are commonly encountered in society. This study presents health-related quality of life differences in thyroidectomies performed for benign and malignant diseases and the factors affecting this. Design. Patients who underwent thyroidectomy for thyroid disease between January 2021 and January 2022 were evaluated prospectively. Subjects and Methods. The SF 36 questionnaire was applied and interpreted at the 1st and 6th months after thyroidectomy in patients over the age of 18 who did not have a history of previous thyroid surgery. Results. The study included a total of 228 patients. Among them, 171 (75%) were female (male/female: 57/171). Multinodular goiter in benign cases and papillary carcinoma in malignant cases were predominant (68.3% and 90.6%, respectively). SF-36 scores were found to be worse in the malignant group. Conclusion. In patients undergoing thyroidectomy for malignant disease, lower quality of life scores were observed in the early postoperative period compared to those undergoing thyroidectomy for benign causes.

    Parathyroid Cancer: Review of Uncommon Disease

    Acta Endo (Buc) 2024 20(2): 212-221 doi: 10.4183/aeb.2024.212

    Abstract
    Parathyroid cancer is an uncommon endocrine malignancy. It has slow clinical course and low malignancy potential. It represents 1% of primary hyperparathyroidism. It results with more agrressive biological behaviour and severe clinical condition than benign reasons. Extended resection in the first operation is essential for PC treatment and decreases local recurrence that is observed in high frequency. Palliative surgery should be considered in patients with unresectable tumor. Immunotherapy and recent interventional radiological procedures are considered for patients that are unfit to surgery. Effect of adjuvant chemotherapy and radiotherapy is limited however recent immunization studies are promising. Parathyroid cancer epidemiology, staging system, diagnosis and advancements in treatment are considered according to recent literature in this review.

    Increased Dietary Intake and Serum Levels of Advanced Glycation End Products (Ages) are Associated With Diabetic Macular Edema

    Acta Endo (Buc) 2022 18(3): 278-287 doi: 10.4183/aeb.2022.278

    Abstract
    Aim. Diabetic macular oedema (DME) can develop at all stages of diabetic retinopathy, causing visual impairment and blindness. Modern diets are high in advanced glycation end products (dAGEs), derived from processing methods, exerting a pivotal role in promoting diabetic retinopathy risk. In present study, we investigate the relationship between dietary and serum levels of AGEs and DME in type 2 diabetic subjects. Methods. This case-control study was conducted between July 2018 and February 2019 on 50 case subjects with DME and 40 healthy controls without DM without DME. The sociodemographic characteristics, nutritional status, and anthropometric measurements were evaluated. The advanced glycation end products (AGEs) and receptor for AGEs (sRAGE) levels in serum were analysed. Results. The AGEs levels of the DME group were higher than in the control group (p <0.05). sRAGE levels were higher in the DME group, but not statistically significant (p >0.05). The dietary intake of AGEs was higher in the DME group (p <0.05). It was found that an increase in neck circumference increased the risk of DME (p <0.001). Conclusion. A positive correlation was found between DME and AGEs, dAGE, neck circumference, and waist circumference. For the validity of these results, studies, including controlled nutrition interventions, are needed.

    Evaluation of the Association of Plasma Pentraxin-3 Levels with Carotid Intima-Media Thickness and High-Sensitive CRP in Patients with Subclinical Hypothyroidism

    Acta Endo (Buc) 2023 19(3): 286-291 doi: 10.4183/aeb.2023.286

    Abstract
    Context. Inflammation-related markers may predict cardiovascular diseases. Objective. In this study, it was aimed to assess pentraxin-3 (PTX-3) levels and its relationship with carotid intima-media thickness (CIMT) and high-sensitive C-reactive protein (hsCRP) in patients with subclinical hypothyroidism. Design. Prospective cross-sectional study Methods. This study included 60 patients (aged 30-60 years) with subclinical hypothyroidism and 30 healthy volunteers as controls. The demographic characteristics and anthropometric measurements were performed in all patients and controls. In addition, sonographic carotid artery examination, thyroid functional tests, lipid profile, hsCRP, and PTX-3 levels of the participants were investigated. Results. The PTX-3, hsCRP levels and CIMT were higher in patients with subclinical hypothyroidism when compared to controls (p=0.008, p=0.001, p<0.001, respectively). The PTX-3 level was strongly correlated with hsCRP (r=0.865; p<0.001), but no such correlation was detected with CIMT (r=-0.255; p=0.50). In binominal logistic regression analysis, it was found that CIMT and serum uric acid levels were independent parameters associated with subclinical hypothyroidism. In ROC analysis, a cut-off value of >3.75 ng/mL for serum PTX-3 level predicted subclinical hypothyroidism with a sensitivity of 60% and specificity of 60.7% (AUC: 0.672, p=0.004). Conclusion. Showing inflammation and endothelial dysfunction, the PTX-3 may be a helpful marker in patients with subclinical hypothyroidism associated with increased risk for cardiovascular disease.

    Screening of PROP-1, LHX2 and POU1F1 Mutations in Patients with Ectopic Posterior Pituitary Gland

    Acta Endo (Buc) 2018 14(3): 300-306 doi: 10.4183/aeb.2018.300

    Abstract
    Objective. Ectopic posterior pituitary gland (EPP) is usually characterized by an abnormal pituitary stalk and hypoplasia of the anterior hypophysis. The genetic mechanisms involved in the development of EPP remain uncertain. The aim of this study is to determine whether mutations in the three genes, PROP-1, LHX2, and POU1F1, are associated with the risk for and the characteristics of EPP. Methods. In the Endocrinology Outpatient Clinic of “Dr. Behcet Uz” Children’s Hospital, 27 patients with EPP were submitted to sequencing analyses of the PROP-1, LHX2, and POU1F1 genes. Results. Growth hormone, thyrotropin, corticotropin, gonadotropin, and vasopressin deficiency were observed in 22 (81.5%), 23 (85.2%), 17 (63%), 14 (51.9%), and two (7.4%) patients. Thirteen patients (48.1%) presented with hyperprolactinemia. Fourteen patients (51%) had a history of birth dystocia, and 12 cases (42.1%) had a history of breech presentation. Central nervous system abnormalities included five cases with corpus callosum agenesis, one case with schizencephaly, and one case with Chiari type 1 malformation. We identified a homozygous p.S109* mutation in exon 2 in one male patient with EPP and two different PROP1 gene polymorphisms (A142T or c.109+3 G>A polymorphism) in thirteen patients. Conclusions. Our results suggest that PROP1 gene abnormalities might explain the genetic mechanisms involved in the development of EPP.

    Weight Loss and Beyond, Assessment of Quality of Life after Laparoscopic Sleeve Gastrectomy Using Baros in Patients with Obesity in Turkey

    Acta Endo (Buc) 2023 19(3): 326-332 doi: 10.4183/aeb.2023.326

    Abstract
    Context. Sleeve gastrectomy is an effective method for management of obesity. The Bariatric Analysis and Reporting Outcome System (BAROS) is a comprehensive and standard system for the assessment of outcomes of weight loss surgery. It is consisted of weight loss, changes in obesityrelated comorbidities and quality of life measurements. We investigated results of the sleeve gastrectomy based on the BAROS. Material and Methods. Outcomes of laparoscopic sleeve gastrectomy surgery was studied in 45 patients with obesity (11 male, 34 female), after 45 months in Turkey. Results. Total weight loss was 26.4±0.1% of body weight at 45 months. Weight regain was seen in 97.8% of the patients with an average 14.5 kg and 13.7% body mass index points. The surgery caused 76% decrease in incidence of obstructive sleep apnea, 73% decrease in type 2 diabetes, 63% decrease in hyperlipidemia and 62% decrease in hypertension. Significant improvement is observed in all quality-of-life parameters. The final score of the BAROS was 4.23±1.02. Conclusion. Based on BAROS, sleeve gastrectomy provides significant improvements in weight loss, incidence of medical comorbidities and quality of life after surgery. Future studies should address prevention of weight regain after the surgery.

    Vitamin D Deficiency is a Predictor of Mortality in Elderly with Chronic Heart Failure

    Acta Endo (Buc) 2021 17(3): 358-364 doi: 10.4183/aeb.2021.358

    Abstract
    Context. The prevalence of both heart failure and vitamin D deficiency increases with age and is associated with poor outcome in the elderly. Objectives. We aimed to investigate the relationship between all-cause mortality and vitamin D deficiency in elderly patients with chronic heart failure. Design. It is a retrospective, observational crosssectional study. Median follow-up time was 497 days. Subjects and Methods. 302 patients aged ≥65 years heart failure patients was categorized into tertiles based on the 25-hydroxy-vitamin D levels. Clinical and laboratory parameters were evaluated according to tertiles. Hospitalization rates and overall survival were compared between tertiles. Independent predictors of all cause mortality were defined. Results. Patients with low vitamin D tertile were mostly women (p=0.001), and had a worse NYHA functional class (p=0.005). During follow-up, deaths were more frequent in the first tertile (p = 0.001). All-cause mortality increased significantly with decreasing vitamin D tertiles (from third tertile 7.9%, to 11.9%, to 26%; log rank test p=0.003). No significant difference was observed at the composite endpoint of mortality or HF hospitalizations (P=0.451). Multivariate analysis supported that low vitamin D concentration was an independent predictor of all causes of mortality (HR 0.93; 95% CI 0.89-0.97; p=0.004). Conclusions. Low vitamin D levels were independent predictors of all-cause mortality in the elderly population with chronic heart failure.

    Cushing’s Syndrome Due to Primary Bilateral Macronodular Adrenal Hyperplasia and Metachronous Pheochromocytoma

    Acta Endo (Buc) 2022 18(3): 361-367 doi: 10.4183/aeb.2022.361

    Abstract
    Introduction. Primary bilateral macronodular adrenal hyperplasia (PBMAH) is one of the uncommon causes of endogenous Cushing’s syndrome (CS). Pheochromocytoma (PCC) is another adrenal tumor which is derived from neural crest arising in the adrenal medulla. Here we are reporting a case with recurrent overt CS due to PBMAH, 2 years after unilateral adrenalectomy, concomitant with recently developed PCC. Case Presentation. A 43-year-old woman was admitted to our clinic with a 30 kg weight gain, proximal muscle weakness, menstrual irregularity, easy bruising and excessive hair growth on face and body.The lab results were compatible with a diagnosis of solely ACTH-independent CS. Screening showed bilateral macronodular lesions and she underwent right adrenalectomy. Postoperatively, she had lost weight and her well-being had improved; 2 years later, she developed CS and paroxysmal hypertension. The left adrenal gland was laparoscopically removed. Histopatologically, the lesion was reported as a typical PCC and macronodularmicronodular hyperplasia of the adrenal tissue surrounding that lesion. Conclusions. Pheochromocytoma with synchronous ACTH-independent CS originating from the same adrenal gland is very rare. To the best of our knowledge,our case is the first one describing the coexistence of overt ACTHindependent CS due to PBMAH and metachronous PCC. The importance of detailed re-evaluation of patients with recurrent ACTH-independent CS is highlighted here.
