ACTA ENDOCRINOLOGICA (BUC)

Background. To investigate the association between inflammatory factors, such as complete blood count (CBC) components, neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and gestational diabetes mellitus (GDM). Methods. A total of 635 pregnant women with GDM and 296 with normal pregnancies at 7–13 weeks of gestation who underwent prenatal examinations in the obstetrics department were enrolled (June 2020–December 2020). CBC parameters, including WBC, neutrophil, lymphocyte (LYM), monocyte (MON), red blood cell (RBC), hemoglobin (HGB), mean corpuscular volume (MCV), platelet (PLT), platelet accumulation (PCT), mean platelet volume (MPV), NLR, MLR, PLR, alanine transaminase (ALT), aspartate transaminase (AST), gamma-glutamyl transferase (GGT), and other parameters were assessed. The receiver operating characteristic (ROC) curve was used to analyze the screening effects of the variables on the development of GDM. Results. There were significant differences in the blood levels of WBC, NEU, LYM, MON, RBC, HGB, PCT, ALT, AST, GGT, NLR, and MLR between the GDM and control groups (P<0.05). The diagnostic level of MON was the highest among all factors. Conclusion. Inflammatory factors (WBC, NEU, LYM, MON, NLR, and MLR counts) were correlated with GDM.

Objective. Romania has no national guidelines for hypothyroidism treatment, nor are there any recommendations from national societies to adhere to international guidelines. Our aim was to identify the attitudes of Romanian physicians relating to hypothyroidism treatment focusing on available formulations of levothyroxine (LT4). Methods. All 748 members of the Romanian Society of Endocrinology were invited to participate in a web-based survey. A total of 316 (42.24%) members responded, of whom 222 (70.2%) completed all questions. Results. Half of the respondents recommended LT4 treatment in euthyroid patients, from 3.6% in euthyroid patients with obesity to 36.4% in euthyroid females with infertility associated with high levels of thyroid antibodies. LT4 was considered the preferred treatment for hypothyroidism (compared to combination treatment of LT4 with LT3 or LT3 alone) by 98.6% of respondents. LT4 in liquid solution was preferred over tablets if malabsorption is suspected (56.5% vs. 27.3%), for patients with unexplained poor biochemical control (52.5% vs. 22.9%) and for patients not able to adhere to ingesting LT4 fasted (74.0% vs. 9.8%). The most and least probable explanations for persistent symptoms in patients with hypothyroidism who achieve a normal TSH under medication were “psychosocial factors” and “burden of having to take medication”, respectively. Conclusion. A significant proportion of Romanian physicians would use LT4 in some groups of euthyroid patients, contrary to current evidence. The preferred treatment for hypothyroidism was LT4. Alternative LT4 formulations (liquid solution) are considered in specific clinical conditions. Diversification of available thyroid hormone formulations was readily incorporated into everyday practice.

A 20-year-old woman was studied because of lack of spontaneous pubertal development and primary amenorrhea. At the moment of examination in the Medical Genetics Department she had normal height, sparse axillary and pubic hair, but breasts were well developed (she already had some estrogen therapy). She had normal but infantile external genitalia, normal vagina and small uterus. Laparoscopic investigation suggested the presence of gonadoblastoma in the dysgenetic gonads and histopathologic examination confirmed the diagnosis. The karyotype revealed a 46, XY chromosome constitution in lymphocytes, without structural defects of X or Y chromosomes. Because of the risk of malignancy, gonadectomy was performed.

Background and Objectives. Levels of insulin-like growth factor-I are characteristically low in Laron syndrome which is a factor that has important roles on vascular health and development. Congenital insulin-like growth factor-I deficiency was reported to be associated with some vascular disorders. However, vasculitis diseases and Laron Syndrome association has not been reported in English literature up to date. Patient. We report the case of a two and a half years old Turkish girl, who was diagnosed as Laron syndrome when she was 12 months old. She presented with acute vasculitis lesions. Her physical examination and laboratory studies did not reveal a specific infectious agent or also an autoimmune disease was not detected. Her lesions disappeared during hospitalization without a complication. Conclusion. Since insulin-like growth factor-I reduces endothelial cell oxidative stress and maintains the structural integrity of vessels, some common mechanisms might be responsible for the occurrence of vasculitis in this patient with Laron syndome. The role of insulin-like growth factor-I and recombinant human insulin-like growth factor-I treatment choice in vasculitis diseases is a matter of investigation.

Context. Impaired flow mediated dilatation (FMD) and increased carotid intima media thickness (CIMT) are the antecedent forms of atherosclerosis. Objective. The aim of this study was to evaluate vascular structural and functional changes in patients with asymptomatic primary hyperparathyroidism (APHPT), and whether biochemical alterations, related with PHPT and oxidative stress marker serum advanced oxidation protein products (AOPPs), may have influence on vascular alterations. Design. This is a cross sectional clinical study. Subject and Methods: Thirty-four patients with APHPT and 29 sex- and age and cardiovascular risk factors matched control cases were included in this study. Endothelial function was evaluated by FMD of the brachial artery; CIMT was measured by ultrasonography; in addition serum AOPPs and biochemical parameters were determined. Results. Serum Ca levels were higher in the patient group [10.93±0.60mg/dL vs. 9.45±0.31; p<0.001]. FMD measurement was significantly lower in patients group [0.07 (0.01-0.26) % vs. 0.14 (0.04-0.22) %; p=0.01]. CIMT measurements were comparable between the groups [52 (35- 69) mm vs. 56 (38-70) mm; p=0.821]. AOPPs levels were significantly higher in the patients [136.43 (55.14-1352) mmol/L vs. 84 (53.18-595.48) mmol/L; p=0.026]. There were significant negative correlations between FMD and serum Ca (r=–0.339, p<0.001); and serum AOPPs levels (r=–0.275, p<0.005). Serum Ca (p=0.007, β=–0.353) and AOPPs (p=0.024, β=–0.243) levels and hyperlipidemia (p=0.024, β=–0.288) were the predictors of FMD. Conclusions. Vascular endothelial function is impaired in patients with APHPT. Hypercalcemia, increased oxidative stress and hyperlipidemia may have role in the pathogenesis of endothelial dysfunction in patients with APHPT.

Context. High heritability of body composition variables is well-known, however, longitudinal effect of genes is still unclear. Objective. The aim of this study was to investigate the pattern of longitudinal changes in anthropometric variables in a small cohort of twins. Design. Longitudinal classical twin study, performed in 2009 and in 2011 on the same twin pairs. Subjects and Methods. Eighteen healthy adult Hungarian twin pairs (13 monozygotic [MZ], 5 dizygotic [DZ]; mean age 54.0 ± 15.2 years; average body mass index 24.4±5.4 kg/m2 in 2009 and 25.1±4.7 kg/m2 in 2011, respectively) recruited from the Hungarian Twin Registry underwent bioimpedance analysis (OMRON). Results. Significant, higher positive intrapair correlations were detected in the longitudinal change in weight (p<0.05), body fat mass (p<0.01), non-fat mass (p<0.01), and body mass index (p<0.01) in MZ compared to DZ twins, suggesting the possibility of longitudinal genetic determinants. Negative associations were observed with regard to the two-year change in waist and hip circumferences, suggesting the longitudinal role of environmental factors in these phenotypes. Conclusions. The findings of the present human twin study suggest that weight, body fat mass, non-fat mass, and body mass index are determined genetically and longer exposure to pathologic environmental factors is necessary to elicit alterations in the regulation of these parameters. Longer-term confirmation in a larger sample is required to confirm these results.

A 54 years old man, who had undergone a cystectomy and urinary diversion surgery 31 years previously, complained of progressive generalized bone pain, muscle weakness and walking abnormality for six months. Laboratory investigations revealed elevated alkaline phosphatase, high serum chloride level and metabolic acidosis. Osteomalacia was suspected due to clinical and laboratory findings. Osteomalacia due to hyperchloremic metabolic acidosis is a complication of urinary diversion. Regular monitoring of pH, chloride, bicarbonate, and calcium-phosphorus metabolism is therefore essential for early diagnosis and treatment.

Apart from endocrine and reproductive disturbances, polycystic ovary syndrome (PCOS) clusters several cardiovascular risk factors, mainly insulin resistance, obesity and dyslipidemia. In addition, androgen excess\r\nsignificantly contributes to enhanced vascular risk. Several mediators of endothelial dysfunction have been characterized lately in patients with PCOS, emerging as independent\r\npredictors of vascular abnormalities and potentially useful biomarkers of endothelial impairment in PCOS.

COVID-19 is a viral disease that is recognized now as a pandemic by the World Health Organization. It is known that some viral infections may trigger autoimmune diseases. It has been revealed that COVID-19 may also lead to the pathogenesis of some autoimmune diseases, including Type 1 DM (T1DM) and autoimmune thyroid diseases. Here, we aimed to present a young female patient with COVID-19, who we followed up in our clinic, who presented with diabetic ketoacidosis (DKA), and developed Hashimoto’s disease during the treatment process. In order to emphasize that COVID-19 may trigger the emergence of T1DM, that it may mask nonspecific DKA symptoms like nausea and vomiting, that it may cause delay in diagnosis of DKA, and also to emphasize the importance of evaluating other autoimmune diseases accompanying COVID-19, we found it appropriate to present this case.
