    Risk Factors for Acute Kidney Injury Associated with Severe Hypothyroidism

    Acta Endo (Buc) 2023 19(4): 456-462 doi: 10.4183/aeb.2023.456

    Abstract
    Objective. This study aims to investigate the factors affecting development of acute kidney injury (AKI) in patients with severe hypothyroidism. Methods. This retrospective observational study involved patients with primary hypothyroidism and thyroid stimulating hormone (TSH) levels of more than 50 mIU/L at their review in the endocrinology outpatient clinic, between January 2015 and April 2021. Factors affecting the development of AKI were examined by logistic regression analysis. Results. A total of 100 patients, 20 (11 male (M), 9 female (F)) in the AKI (case) group and 80 (23 M, 57 F) patients in control group, were included in our study. The median age of the case group (56 years, interquartile range (IQR) 44.3–68.5) was significantly higher than the control group (49 years, IQR 32.3–60; p = 0.027), and the ratio of males to females was significantly higher in the case group (p = 0.001). Multivariate logistic regression analyses showed that hypothyroidism diagnosed after the age of 60 years (odds ratio (OR) 59.674, 95% confidence intervals (CI) 5.955–598.031; p = 0.001), free triiodothyronine (FT3) < 1.3 pg/mL (OR 17.151, 95% CI 2.491–118.089; p = 0.004) and creatine kinase (CK) > 1000 U/L (OR 1.522, 95% CI 1.602– 82.848; p = 0.015) were predictors for the development of AKI in patients with severe hypothyroidism. Conclusion. We recommend close follow-up and monitoring of patients with AKI caused by severe hypothyroidism if patients who are diagnosed at age > 60 years, CK > 1000 U/L or FT3 < 1.3 pg/mL.

    Association of the Human PPARY2 PRO12ALA Polymorphism with Obesity in a Population from Turkey

    Acta Endo (Buc) 2018 14(4): 459-465 doi: 10.4183/aeb.2018.459

    Abstract
    Background. There have been a number of reports on the relationship between the PPARγ2 Pro12Ala genotype and the development of obesity. Objective. A case-control survey was designed to investigate the potential association between a Pro12Ala polymorphism in the PPARγ2 gene and obesity and/or obesity-related phenotypes in a population from Turkey. Materials and methods. The polymerase chain reaction and restriction enzyme digestion were used to genotype the Pro12Ala polymorphism of the PPARγ2 gene in 149 unrelated obese and 105 non-obese control subjects from Turkey. The data were analyzed statistically. Results. We found that the overall minor allele frequency was 0.12 in cases and 0.095 in controls. In terms of genotype distribution and allele frequencies among the cases versus controls in the population studied, only the genderstratified analysis revealed a significantly higher frequency of Pro/Ala genotype within males. The polymorphism was associated with significantly higher weight, height, waist circumference, central adiposity (waist-to-hip ratio, WHR), lean body weight as well as dry body weight, but not overall adiposity (total body fat percentage, TBF) in cases carrying Ala allele (Pro/Ala or Ala/Ala). However, in the subjects carrying Ala allele of the control group, WHR values were found significantly lower. Conclusion. Our results showed that the Pro12Ala polymorphism in the PPARγ2 gene is associated with obesity in the studied adult population from Turkey. These data suggest that the Pro12Ala polymorphism in PPARγ2 may be a potential genetic risk factor for central obesity.

    The Effect of Short Term Alpha Lipoic Acid Administration on Adiponectin and Body Weight in Type 2 Diabetes Mellitus Patient

    Acta Endo (Buc) 2017 13(4): 461-466 doi: 10.4183/aeb.2017.461

    Abstract
    Background. Alpha lipoic acid (ALA) acts as essential co-factor for mitochondrion respiratory enzymes. It has an increasing importance in diabetic neuropathy treatment. Its positive effects on weight gain and metabolic parameters have also been discussed. In this study, we aimed to search for the effect of ALA on weight, appetite, adiponectin and metabolic parameters in type 2 diabetes mellitus patients. Methods. This study is designed as a randomised, double-blind, placebo controlled, prospective study. 23 type 2 diabetes mellitus patients with peripheral neuropathy (6 normal weight, 17 obese) and 21 normal weight control group were included in the study. Patients were given 600mg/day oral ALA for 6 weeks, added to their routine therapy. Body mass index (BMI), adiponectin, fasting plasma glucose, HbA1C, lipid parameters and CRP levels were tested before and after ALA treatment. Results were evaluated using SPSS 15.0 for Windows. Results. Adiponectin levels were statistically significantly lower and CRP levels were higher in diabetes group when compared to control group. Although ALA treatment caused a slight weight loss, it was not statistically significant. Appetite scores were decreased in the diabetes group but it did not cause statistically significant weight loss. There was no significant change in metabolic parameters or adiponectin after the treatment. Conclusions. 600mg/dL ALA treatment for 6 weeks did not favor for metabolic parameters in type 2 diabetes patients. This result might be due to the dose or the duration of the treatment, genetic predisposition or dietery habits. Trial of higher doses for long terms might be needed for recovery.

    Anti-Implantation Activity of Methtrexate and Leucovorin in Albino Rats

    Acta Endo (Buc) 2011 7(4): 463-474 doi: 10.4183/aeb.2011.463

    Abstract
    Background. The loss of reproductive function is one of the mostimportant adverse effects of chemotherapy. Folic acid deficiency may be harmful in pregnancy. Hence, it is imperative to investigate if leucovorin (LCN), a folinic\r\nacid supplementation and withdrawal of MTX treatment facilitate maintenance of pregnancy in albino rats.\r\nAim. The aim of this study was to examine the role of leucovorin (LCN) and withdrawal of MTX treatment in the\r\nprotection of pregnancy at very early stage of pregnancy in MTX treated rats.\r\nAnimals and Methods. Rats with regular oestrous cycle were randomly divided into five groups (n=6) as follows: Control,\r\nMTXLD (low dose), MTXHD (high dose), MTXHD + LCN (leucovorin), and MTXHD + WD (withdrawal). Animals were treated intramuscularly (im) on days 1-5 of pregnancy. MTXHD treatment was withdrawn and female rats showing regular cycle were caged with male rats. Laparotomy was performed on day 8 of pregnancy to note the number of implantation sites. Rats were sacrificed on day 20.\r\nResults. MTX significantly reduced maternal weights, number of corpora lutea, and implantation sites. 100% foetal\r\nresorption was prevalent in MTX treated groups. LCN supplementation did not help maintain pregnancy. While approximately 45% foetal resorption was observed in\r\nwithdrawal group.

    Assessment of the Shox Gene and Chromosomal Abnormalities by Molecular and Classical Cytogenetics in Patients with Short Stature

    Acta Endo (Buc) 2015 11(4): 463-469 doi: 10.4183/aeb.2015.463

    Abstract
    Context. Genetic factors are responsible for up to 80% of height variation in humans. SHOX gene mutation could be an important etiologic factor in short stature, being observed in up to 15% of patients. Aim. Our aim was to evaluate the genetic causes of short stature, using classical and molecular cytogenetic techniques by analyzing a group of Romanian patients diagnosed with short stature. Material and methods. Seventy nine patients were analyzed and the main criteria for inclusion in the study was the presence of a height below -2DS. For each of these patients a karyotype was performed. In those with normal karyotype it was indicated FISH technique using probes for SHOX and centromeric regions. Results and discussion. The karyotype revealed the presence of abnormalities in 13 patients (16%), 62% (8 patients) of these being represented by heterosomal abnormalities. SHOX deletion was seen in one patient (2.3%) with short stature and normal karyotype. The initial analysis of the cases with short stature directly by FISH technique can be proposed, using probes for X chromosome centromere and SHOX gene, because it allows, approximately at the same costs with the karyotype, but faster and at a higher rate of mosaicism detection, the explanation of short stature by sex chromosomes abnormalities.

    The Effect of Therapy with Insulin Analogues (Aspart and Glargine) on Oxidative Stress Parameters in Patients with Type 1 Diabetes Mellitus

    Acta Endo (Buc) 2023 19(4): 463-470 doi: 10.4183/aeb.2023.463

    Abstract
    Context. There are evidences that excessive production of reactive oxygen species is one of important abnormalities that contribute to development of chronic diabetic complications. Objective. To test the effect of intensive insulin therapy with analogues through the examining the level of oxidative stress parameters. Subjects and Methods. Comparison of data obtained by prospective analysis in 49 patients with T1DM was used, before and after six months of intensive insulin analog therapy. Results. The values of all three investigated parameters of oxidative stress malondialdehyde (MDA); xanthine oxidase (XO) and nitrates and nitrites (NOx) in our population with T1DM compared to the control (group of 42 voluntary blood donors) are statistically higher. The levels of antioxidant protection parameters compared to the control group also differ; the activities of catalase and glutathione peroxidase (GPx) are statistically higher in our population of T1DM patients compared to the control and superoxide dismutase (SOD) activities are statistically lower. The values of all three examined parameters of oxidative stress decrease after six months of intensive insulin analog therapy and were statistically lower after the therapy: for MDA p<0.001, for XO p<0.01 and for NOx p<0.05. The activities of catalase (p<0.001) and GPx (p<0.01) both decrease with therapy, while the activity of SOD is highest after the sixth month of therapy (p<0.001). Conclusion. In our patients with T1DM compared to the control the level of oxidative stress is significantly higher. Intensive insulin analog therapy with aspart and glargine promotes predominantly the improvement of oxidative stress, and in a less degree antioxidant protection.

    Aplastic anemia during antithyroid drugs in hyperthyroidism. Case report

    Acta Endo (Buc) 2008 4(4): 465-470 doi: 10.4183/aeb.2009.465

    Abstract
    It is known that antithyroid drugs have been associated with development of agranulocytosis or secondary autoimmune neutropenia. Aplastic anemia is an unusual but severe form of haematological complication after antithyroid drugs. We are presenting a case of a 34-year old woman diagnosed with Graves&#8217; disease, based on ophthalmopathy, symptoms and signs of hyperthyroidism, a diffuse enlargement of the thyroid gland; TSH level= 0.17 mU/L, fT4= 28 pmol/L, T3= 4.92 nmol/L, thyroglobulin antibodies= 117 IU/mL. The patient developed, after six weeks of treatment with Carbimazole 60 mg daily, a moderate aplastic anemia (pancytopenia: haemoglobin level= 8.2 g/dL, granulocytes= 800/mmc, platelets= 40,000/mmc; hypocellular bone marrow with increased fat cells and lymphocytosis, plasmocytosis and mastocytosis, in the absence of neoplastic or infectious infiltrations, possibly with immune aetiology suggested by disturbance of CD4/CD8 and favourable response after immunosuppressive therapy). Therapy was represented by: stopping the administration of carbimazole, broad spectrum antibiotics, antiviral and antifungal prophylaxis,general and dental hygiene, high doses of methylprednisolone followed by Cyclosporin A 12 mg/kg/day, with favourable evolution. The serum T3 and T3/T4 ratio increased after the antithyroid drug regimen was stopped . After 3 months of therapy, the patient was in complete haematological response with haemoglobin value= 11.8g/dL, granulocytes= 2.200/mmc, platelets = 130,000/mmc and was submitted to subtotal thyroidectomy.

    A Child with Laron Syndrome Associated with Vasculitis

    Acta Endo (Buc) 2016 12(4): 465-468 doi: 10.4183/aeb.2016.465

    Abstract
    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.

    Usefulness of Strain Measurement in the Assessment of Carotid Arteries Stiffness in Type 1 Diabetes Patients

    Acta Endo (Buc) 2015 11(4): 470-475 doi: 10.4183/aeb.2015.470

    Abstract
    Context. Increased arterial stiffness is an independent risk factor of cardiovascular events in patients with diabetes mellitus (DM). Objective. We aimed to evaluate elastic properties of common carotid arteries (CCA) in patients with DM type 1 (T1DM) by means of ultrasonographically based technique – two-dimensional speckle tracking. Design. Case-control observational study. Subjects and Methods. Examination of both CCA was performed in 50 patients with T1DM. The mean age of patients was 36.1 (±11.9) years and duration of diabetes was 8.9 (±11.9) years. 28 controls (mean age 38.6 ± 10.8) were examined according to the same protocol. Strain and strain rate reflected arterial wall stiffness and intimamedia complex thickness (IMCT) indicate presence of morphological changes. Parameters were compared between groups and regression analysis was performed to predict determinants of evaluated parameters. Results. Patients with T1DM had significantly more elastic CCA arteries than the healthy control (mean strain [%]: 6.05 ± 2.55 vs. 5.19 ± 1.79, p=0.0295; mean strain rate [1/s]: 0.91 ± 0.33 vs. 0.78 ± 0.25, p= 0.0142; respectively), but no significant differences in IMCT were revealed (0.49mm ± 0.12mm vs. 0.49mm ± 0.10mm, p=0.9893; respectively). Women had significantly decreased strain parameters in comparison with men, although the difference in IMCT was not significant. Conclusions. Two-dimensional speckle tracing revealed increased elasticity of CCA in patients with T1DM with no deterioration of arterial wall.

    New Molecular and Metabolic Aspects in Romanian Patients with Classic 21-Hydroxylase Deficiency

    Acta Endo (Buc) 2012 8(3): 471-478 doi: 10.4183/aeb.2012.471

    Abstract
    21-hydroxylase deficiency is with 90% the most frequent cause of congenital adrenal hyperplasia and is due to an inborn enzymatic defect of adrenal steroidogenesis inherited in an autosomal recessive manner. Here we report on the mutational spectrum of Romanian patients with classic\r\n21-hydroxylase deficiency and describe differences to other surrounding or Latin countries. The overall genotype-phenotype correlation was 87.8%. A new mutation P94L has been identified in a subgroup of patients with 11-?-hydroxylase deficiency. Furthermore, we address the issues of early alterations in bone mineral density and metabolism as well as early discrete alterations in lipid and carbohydrate metabolism with enhancement of the atherogenic small dense LDL-subfraction and emerging insulin resistance. The relationship of these discrete changes to treatment variables such as the mean and cumulative hydrocortisone dose stress once more the importance of an optimal glucocorticoid treatment with the lowest effective individual doses, to preclude the achievement of a suboptimal peak bone mass as well as the early appearance of traits of the metabolic syndrome.
