ACTA ENDOCRINOLOGICA (BUC)

Antithyroidperoxidase antibodies (ATPO), antithyroid antibodies directed to thyroid follicular microsomes, are recognized as the test for diagnosis of Hashimoto?s thyroiditis. The study tries to establish relationships between the ATPO and echographic picture in thyroiditis. In 383 patients (15-85 years, 354 women and 29 men) the antithyroperoxidase assay was performed using ELISA technique, (N= 0 - 34 ?U/ml). Therefore, 185 patients had Hashimoto thyroiditis and 198 patients were excluded. The images obtained from all the patients and controls, classified in 7 patterns, showed that pattern #1 (?hypoechogenic and pseudonodular?) could be considered as pathognomonic for the diagnosis of Hashimoto thyroiditis: the predictive positive value was 95.61%. Five hundred and six evaluation moments echo-ATPO were correlated in both Hashimoto thyroiditis and control group. In patients with Hashimoto thyroiditis, 301 evaluations were performed, both immune (ATPO) and echographic. For all cases and patterns (36 degrees of freedom), &#967;2 test was 77.35. P value was < 0.0001. When ATPO are high, pattern #1 was the most frequent, while for pattern #7 (normal), ATPO should be the lowest. The ATPO evolution can be considered mostly as unchanged during over one year observation. There is no correlation between the ATPO level, echographic pattern and thyroid function: the patients were in the same percent euthyroid and hypothyroid associated with similar echographic patterns. In conclusion, this study shows a highly correlative relationship between the echographic pattern and ATPO levels in Hashimoto patients.

Background. Alcohol ingestion can induce either a hypoglycemia or a hyperglycemia,\r\nin patients with acute and chronic ethanol poisoning, unknown with diabetes mellitus.\r\nAim. The aim of this study was to evaluate whether 5 hours prolonged oral glucose\r\ntolerance test (5h-OGTT) is useful in evaluating the abnormalities of glucose metabolism in\r\nacute and chronic ethanol poisoning, in comparison with standard methods (fasting blood\r\nglucose - FBG, and/or 2h-OGTT).\r\nMethods. 497 consecutive patients were enrolled in a 34 months cross sectional study.\r\nIn all cases, glucose tolerance was assessed by a 75-g oral glucose tolerance, OGTT 2 hours,\r\nprolonged to 5 hours. The relationship between clinical and biochemical variables of ethanol\r\npoisoning (liver status, lipid profile, metabolic syndrome) and glucose tolerance was\r\ninvestigated. Risk factors for hypoglycemia in ethanol poisoning were identified.\r\nResults. 349 subjects presented acute ethanol poisoning, and 148 subjects had chronic\r\nethanol poisoning. 254 patients (51.10%) had documented alcoholic liver disease (ALD -\r\nclinical, biochemical and imagistic criteria). Glucose metabolism abnormalities were\r\nrecorded in 143 subjects with chronic ethanol poisoning and ALD (96.63%), and in 207\r\ncases with acute alcohol poisoning (59.31%). 371 patients (74.65%) showed normal FBG,\r\ndiabetes mellitus (DM) was diagnosed in 54 subjects (10.86%), impaired glucose tolerance\r\n(IGT) in 43 subjects (8.65%), delayed hypoglycemia in 172 subjects (34.60%) and normal\r\nglucose tolerance (NGT) in 147 subjects (29.57%) using OGTT and ADA diagnosis criteria.\r\nHypoglycemia was recorded in more than two thirds of acutely poisoned patients, when alcohol\r\nlevel was 0.5-1.5 g/L. Impaired glucose tolerance (IGT) were recorded in half of patients with\r\nblood ethanol levels > 2.5 g/L.\r\nConclusions. OGTT 2 hours and OGTT 5 hours revealed the same number of patients\r\nwith diabetes mellitus. Frequent co morbidities in patients with ethanol poisoning influence\r\nthe prolonged OGTT and revealed .especially delayed hypoglycemia, and IGT, as an indicator\r\nof alcoholic liver disease (ALD).

Background. Ghrelin is a gastro-duodenal hormone which plays a major role in the regulation of food intake, energy balance and gastrokinesis. Ghrelin represents a novel biological marker for assessment of the presence as well as the severity of liver cirrhosis. We aimed to measure the level of plasma ghrelin in patients with liver cirrhosis (compensated and decompensated) and to correlate its level with different studied clinical and laboratory parameters. Subjects and methods. 40 cirrhotic patients were included in a cross-sectional study and divided equally according to the Child-Pugh classification into Group I: patients with compensated liver cirrhosis (Child A), and Group II: patients with decompensated liver cirrhosis (Child B|C). Also, 20 age and sex matched healthy subjects were included as a control group (Group III). All patients were subjected to: full history taking, full clinical examination, routine biochemical studies together with estimation of plasma ghrelin level, assessment of the severity of liver disease according to Child–Pugh classification, also, abdominal ultrasonography was done. Results. Plasma ghrelin level was low among cirrhotic patients (both compensated and decompensated) in comparison to normal control subjects. Conclusion. Ghrelin can be used as a serum biomarker for detection and assessment of the severity of liver cirrhosis.

Introduction: Pseudo-primary hyperaldosteronism of pregnancy was previously reported by our group during correction in twin-to-twin transfusion syndrome (TTTS). Aim: Focus on plasma volume changes and renin-angiotensin (RAS) and aldosterone response in 45 TTTS patients requiring amnioreductions above 1000 ml for severe hydramnios. Methods: 45 patients necessitating placental surgery and amnioreduction >1000ml for severe TTTS, under local anesthesia, as previously described. Assesment of plasma volume variations (%ΔPV) and simultaneous assays of aldosterone, renin, angiotensin II and ANP performed by standard kits prior to, 6 hours after and 12-24 hours after procedure. Statistical results expressed as median and interquartile ranges for non-parametric data, after correction of post-op levels with %ΔPV. Results: Depletion of 1600 ml (1000-3700) amniotic fluid (extravascular depletion) unexpectedly increased the intravascular plasma volume by 20,38% and dramatically changed the hormonal picture of primary hyperaldosteronism. Aldosterone decreased from a median of 730 pg/ml (T0) to 553 pg/ml (T6) to 515,9 pg/ml (T24). ANP increased from 8,95 pg/ml (T0) to 14,51pg/ml (T6) to 19,9 pg/ml (T24) pg/ml (ANOVA p=0,0036), while renin and angiotenin II stayed unchanged (ANOVA p=0,91). Conclusion: Depletion of extracelular fluid (amnioreduction) is indicated for the correction of hyperaldosteronism in pregnancies with severe hydramnios, to reduce to normal the aldosteron levels without the interference of the renin-angiotensin system, while natriuretic activity increases through ANP and, possibly, other less known natriuretic factors .

Context. The socio-economic and medical burden of obesity represents a continuous challenge for both developing and developed countries. For Romania, the available data on the eating patterns, behavior and other components of lifestyle are scarce. Objective. The objective of this study was to assess the prevalence of overweight and obesity in the Romanian general population and to identify lifestyle patterns characteristic for the Romanian population in terms of eating patterns and physical activity. Design. Cross-sectional, epidemiologic, multicenter non-interventional study Subjects and Methods. Between January 2014 and August 2014 were enrolled 2128 adults by 8 investigators spread in the main historical regions of Romania. The following data: demographic, anthropometric, employment status, education, family history, personal medical history, information on the lifestyle and eating habits. Results. The final population included in the analysis presented here consisted of 2103 participants with no missing information on height and weight. The prevalence of overweight and obesity was 31.1% and 21.3%, respectively. The prevalence of obesity was 9.9% in the 18-39 years age group, 30.1% in the 40-59 years age group, 41.6% in the 60- 79 years age group and 24.1% in the ≥80 years age group (p <0.001). Irregular meals together with eating while watching TV were the most frequent unhealthy eating habits of the participants. Conclusions. We found a high prevalence of overweight and obesity among the participants enrolled. Our study has important implications for increasing the knowledge on the prevalence of overweight and obesity in Romania and associated lifestyle habits.

Context. Subacute thyroiditis is an inflammatory thyroid disease, which is treated by nonsteroidal antiinflammatory drugs (NSAIDs) or steroids. Objective. Defining characteristics of patients with subacute thyroiditis at diagnosis and during follow-up. Investigating the efficacies of NSAID and different doses of steroids and their effects on rates of relapse, recurrence, development of hypothyroidism and on quality of life and sleep parameters. Design. A 3-year observational study in a tertiary referral center. Subjects and Methods. A total of 63 patients with subacute thyroiditis were included. Clinical outcomes of patients treated with NSAIDs and NSAID unresponsive patients treated with prednisolone with initial doses of 0.5 mg/kg/day and 15 mg/day were evaluated. Results. White blood cell count at diagnosis was an independent predictor of NSAID unresponsiveness. No relapse or recurrence was observed in patients receiving low dose of steroids. Long symptom duration until diagnosis and treatment with NSAIDs were associated with development of hypothyroidism. Subacute thyroiditis caused significant deterioration in quality of life and sleep of patients and low dose of steroid was as effective as higher doses in improving these parameters. Conclusions. For patients with no response to NSAID therapy, an initial low dose of prednisolone (15 mg/ day) is determined as a safe treatment method when dose reduction is performed with appropriate timing.

Context. Natriuretic peptides (NP) and oxytocin (OT) play an important role in cardiovascular and hydroelectrolytic homeostasis. Changes in NP levels and their roles in cardiovascular adaptations in pregnancy and labor have not been clear. Objective. The present study aimed to investigate the changes and correlations in plasma levels of atrial natriuretic peptide (ANP), C-type natriuretic peptide (CNP), B-type natriuretic peptide (BNP) and OT during labor and the postpartum period. Study design. Blood samples were collected from 29 healthy pregnant women in the active phase of spontaneous labor, 15 minutes after delivery and 3 hours postpartum. Plasma levels of OT and the stable N-terminal fragments of NPs (NT-proANP, NT-proCNP, NT-proBNP) were measured using enzyme or electrochemiluminescence immunoassays. Results. The plasma levels of NT-proANP and NTproCNP significantly decrease 3 hours postpartum compared to the active phase of labor and to 15 minutes after delivery. The plasma NT-proBNP levels significantly higher after delivery and 3 hours postpartum compared to the active phase of labor. A significant correlation exists between OT and NTproANP levels during the active phase of labor and 15 minutes after delivery. Conclusions. The data show that during labor and postpartum, the plasma concentrations of the NPs change differently. Elevations in NT- proBNP after delivery suggest that BNP may be involved in postpartum adaptations. The correlations between OT and ANP levels indicate that OT may be partly responsible for the increased levels of ANP and may have a role in the modification of the cardiovascular system.

Oxytocin is a complex molecule involved in a variety of biological processes at both the central and the peripheral level. Although its role was initially associated almost exclusively with birth and breastfeeding, recent studies are suggesting that in fact oxytocin could be involved in many other physiological and pathological processes. In this way, lately there is a growing interest towards a possible involvement of oxytocin in many etiopathogenic and psychopathological processes, as for example in the affective disorders, where the roles of oxytocin are not yet clearly understood. In this paper we shortly describe the main aspects regarding the relevance of oxytocin administration or its mechanisms in the affective disorders, as well as its relations with the hypothalamic-pituitary-adrenal axis and cortisol secretion. It seems that although the researches on the importance of oxytocin in the affective disorders are rather at the beginning, an increasing number of evidence is supporting the involvement of oxytocin in the pathogenic processes of these psychiatric disorders. Still, the studies covering this topic are still in their early days, and the results that are trying to understand if there is a major role of oxytocin in affective disorders are not consistent enough to draw definitive conclusions and establish with certainty where the place of oxytocin in the affective disorders pathology is
