Diagnostic and therapeutic approach to small bowel carcinoid tumor. Case reportActa Endo (Buc) 2008 4(4): 447-453 doi: 10.4183/aeb.2008.447
AbstractDetecting the primary tumours in carcinoid malignancies is a critical challenge. We report the case of a 25 year old male patient with a typical clinical carcinoid syndrome. Metastatic carcinoid malignancy was easily diagnosed by very high plasma chromogranin, plasma serotonin and urinary 5-Hydroxy-Indol Acetic Acid levels, and the detection of multiple liver metastases by ultrasound. Somatostatin receptor scintigraphy (SRS) failed to detect the primary lesion, as did upper and lower gastrointestinal (GI) tract endoscopy, bronchoscopy, total body CT, MRI, and GI video tract endoscopy; only F-DOPA PET-scan ascertained and accurately localized the primary ileal tumor. Surgery confirmed the localisation, and pathology revealed a 3 cm highly differentiated carcinoid tumor with low proliferation grade (Ki67<2). The therapy with short and long acting somatostatin analogues was started before surgery and continued after surgical intervention. There was a regression of the clinical carcinoid syndrome and a numerical involution of liver metastases, but the levels of chromogranin A and serotonin remained elevated. Other therapeutical option should be discussed. -

The Effect of Exenatide Therapy in Previously Insulin-Treated Type 2 Diabetic PatientsActa Endo (Buc) 2017 13(4): 447-453 doi: 10.4183/aeb.2017.447
AbstractObjective. To evaluate the effect of multiple daily injection (MDI) treatment replaced by Exenatide BID as compared with continuation of MDI. Patients and Methods. A total of 140 patients with type 2 diabetes, taking metformin and multiple daily insulin injections, were randomized to exenatide or insulin group that continued their insulin treatment. Patients were followed-up for 16 weeks. Blood glucose profiles, BMI, waist circumference, HbA1C, serum lipids and side effects were assesssed at weeks 0,12 and 16. Results. There were no significant differences between the two groups with respect to baseline parameters. Glycemic control was similar between the two groups. The mean changes in HbA1C in exenatide group were -0.66±0.63% and in insulin group -0.74±0.92 % (p=0.594). In exenatide group, 59.6 % of patients and in insulin group 85.71 % of patients had maintained or improved glycemic control at the end of the study. In insulin group, insulin requirement increased 5.86 ± 4.46 units/day. Body weight and waist circumference decreased significantly in exenatide treatment group with respect to insulin group (p<0.001). Conclusions. Substituting exenatide for insulin might be an option in insulin-treated, type 2 diabetic patients having obesity, and poor glycemic control. However, patients with longer duration of diabetes and insulin treatment and with lower C-peptide levels might not benefit from exenatide therapy. -

Effectiveness of Anethum Graveolens L. on Antioxidant Status, Thyroid Function and HistopathologyActa Endo (Buc) 2018 14(4): 447-452 doi: 10.4183/aeb.2018.447
AbstractContext. Anethum graveolens L. is used in the treatment of numerous diseases. But there is limited data about the Anethum graveolens efficiency in thyroid tissue. Objective. The aim of this study is to assess the functional and histopathological changes in thyroid tissues from rats treated with Anethum graveolens L. extract. Design. This is an experimental animal study and duration of the study was 30 days. Subjects and Methods. Twenty-eight female Wistar Albino rats were divided into four equal groups. A gavage of Anethum graveolens L. extract at 0, 50, 150 and 300 mg/kg/day doses were given to the rats with 1 mL 0.9% NaCl, respectively, for 30 days. Blood was taken at day 0, 15 and 30. fT3, fT4, TSH values and antioxidant efficiency were observed. Also the thyroidectomy tissue was assessed histopathologically. Results. There is no difference observed in the fT3, fT4 and TSH values of groups 1, 2 and 3 at day 1, 15 and 30 (p>0.05); however, in group 4, TSH value decreased on days 15 and 30 when compared to day 1 and the other groups (p<0.05). Also the hypertrophy and thyroid follicular cell hyperplasia were significantly increased in group 4 (p<0.05). There is no difference in antioxidant efficiency in any of the groups (p>0.05). Conclusion. Anethum graveolens L. extract is effective on both the function and the histology of thyroid tissue but it has no effect on antioxidant status. -

Posttransplant Diabetes Mellitus Incidence and Risk Factors in Adult Liver Transplantation RecipientsActa Endo (Buc) 2020 16(4): 449-453 doi: 10.4183/aeb.2020.449
AbstractAim. Posttransplant diabetes mellitus (PTDM) is a metabolic complication that usually occurs after liver transplantation (LT) due to immunosuppression. In this study, our aim was to identify PTDM incidence after LT in our center and the potential risk factors. Materials and Methods. In this study, 238 adult LT patients were evaluated in terms of PTDM development. Results. Of 238 patients included in the study, 170 (71.4%) were male, 68 (28.6%) were female and the mean age was 43.5± 13.7 years. Of all patients, PTDM developed in 24 (10.1%). Transient-Hyperglycemia (t-HG) was detected in 31 (13%) patients. PTDM and t-HG patients had a greater body weight than non-PTDM patients (BMI kg/ m2 : 27.6± 5.3, 25.8± 4.3and 23.9± 3.3, respectively p<0.001 p= 0.028). PTDM and t-HG patients mean age was higher than non-PTDM patients (51.5± 9.68, 48.2± 11.1 and 41.5± 14 years, respectively, p= 0.002 p= 0.023). In the univariate analysis, the only independent risk factor for PTDM was age (OR 1.93, 95% CI 1.31-2.97). Conclusion. Age is the most important risk factor for PTDM development after LT. PTDM was found more common in the patient group with greater body weight. Patients with older age and greater body weight should be examined more carefully for PTDM before LT. -

Role of Targeting Asymmetric Dimethylarginine in Streptozotocin-Induced Diabetic Nephropathy in Rats: Effects of Taurine and RosiglitazoneActa Endo (Buc) 2015 11(4): 449-456 doi: 10.4183/aeb.2015.449
AbstractIntroduction. Insulin resistance or dysfunction of pancreatic beta cells represents one of the important worldwide endocrine disease challenges. In fact, vascular endothelial dysfunction (VED) is involved in the pathogenesis of one of the most significant causes of diabetes-induced morbidity; diabetic nephropathy (DN). Asymmetric dimethyl arginine (ADMA) is one among other incriminating mechanisms of VED. The aim of this study was to assess whether ADMA modulation could be achieved by taurine or rosiglitazone, and whether they could improve tubulo-interstitial ischemia and subsequent renal damage in experimental DN in rats. Material and methods. 40 male Wistar rats were randomly assigned into 4 groups: normal saline-injected control, diabetic control induced by intraperitoneal injection of streptozotocin (STZ) (45 mg/kg), and two diabetic groups daily treated orally with rosiglitazone (3 mg/kg) and taurine (500 mg/kg) respectively, for 12 weeks after STZ injection. Results. Both rosiglitazone and taurine treatments significantly decreased fasting blood glucose, renal functions (serum creatinine, blood urea nitrogen, albuminuria), and renal oxidant potential (Malondialdehyde), as well as, tumor necrosis factor-alpha (TNF-α). They also significantly improved renal antioxidant capacity (reduced glutathione) and histopathological changes. Furthermore, taurine significantly diminished serum ADMA, while rosiglitazone showed no significant effect. Conclusion. The present study suggests that the treatment with rosiglitazone or taurine can reduce the progression of renal damage in streptozotocin-induced diabetic nephropathy in rats by different mechanisms. However, reducing ADMA could be a potential therapeutic target. -

Phenotypes of patients with type 1 diabetes mellitus and autoimmune diseasesActa Endo (Buc) 2007 3(4): 451-460 doi: 10.4183/aeb.2007.451
AbstractAutoimmune diseases are a heterogeneous group that involves almost any tissue and organ, a patient could frequently present more than one autoimmune disease. Type 1 diabetes mellitus is frequently associated with other autoimmune diseases in polyglandular autoimmune syndrome. Aim of the study is to evaluate a phenotype of diabetic patients with autoimmune diseases. There is a retrospective study; we analyzed type 1 diabetes inpatients from our department in late 4 years based on clinical records. We state that type 1 diabetes mellitus diagnosis is established based on insulin treatment at onset or less than 1 year from onset. We analyzed the presence of the following autoimmune diseases: Graves’ disease, Hashimoto thyroiditis, autoimmune hypothyroidism, Addison’s disease, vitiligo, psoriasis, systemic lupus erythematosus, pernicious anemia. We recorded 151 patients with type 1 diabetes mellitus: 91 (60.3%) women. Mean age was 38.4?15.8 years, mean span of type 1 DM was 12 years, mean age at the onset of DM was 26.5 years, and mean BMI was 23.4 kg /m2. Patients were insulin treated with 2 doses of insulin 11.3%, 3 doses of insulin 41.6%, 4 doses of insulin 45%, and insulin pump 2%. 41 patients (27.2%) associated other autoimmune diseases, most frequently being chronic thyroiditis. Type 1 DM preceded autoimmune disease in 60%. Patients that associated autoimmune disease have mean age at the onset of type 1 DM 29.1 years. Mean glycated hemoglobin among patients with autoimmune diseases was 10.1% vs. 9.9% among patients without autoimmune diseases (NS); mean insulin needs were respectively 0.78 u/kgc vs. 0.72 u/kgc (NS). In conclusion, type 1 DM is frequently associated with other autoimmune diseases, patients being mainly women. The most frequent association is Graves’ disease. In over 50% of cases type 1 DM precedes autoimmune disease with several years. Even though more than half of patients were treated with multiple doses of insulin, glycated hemoglobin was high, slightly higher among patients with autoimmune diseases but the differences were not statistically significant. -

The Effect of Melatonin Against Gastric Oxidative Stress and Dyslipidemia in Streptozotocin-Induced Diabetic RatsActa Endo (Buc) 2018 14(4): 453-458 doi: 10.4183/aeb.2018.453
AbstractObjective. The aim of this study was to evaluate the possible protective effects of MT against gastric oxidative stress and dyslipidemia in streptozotocin (STZ) - induced diabetic rats. Methods. Forty male Wistar rats were randomly divided into five groups: control, diabetic, MT 5 mg/kg+ STZ, MT 10 mg/kg+ STZ and MT 20 mg/kg+ STZ. STZ (60 mg/kg) was intraperitoneally (ip) injected as a single dose for diabetes induction. One week after STZ administration, MT was injected daily as ip for 14 days. The levels of malondialdehyde (MDA), total thiol and glutathione, as well as superoxide dismutase (SOD) and catalase activities were measured in gastric tissue. Serum concentrations of triglycerides (TG), total cholesterol (TC), high density lipoprotein (HDL) and low density lipoprotein (LDL) were also determined. Results. Serum glucose significantly increased in diabetic group compared to control group. STZ induced a significant decrease in gastric tissue levels of total thiol, glutathione, catalase and SOD activities and a significant increase in MDA concentration. In diabetic rats, serum TG, LDL and TC were significantly higher and HDL was significantly lower than in the control group. Treatment of diabetic rats with MT caused a significant increase in gastric total thiol content and glutathione concentration as well as SOD and catalase activities. Gastric MDA concentration and serum LDL, TG and TC were significantly lower in MTtreated groups when compared with diabetic group. Conclusion. These data suggested that MT has a therapeutic effect on gastric oxidative damage and dyslipidemia induced by diabetes that possibly may be due to its antioxidant effects. -

Endoscopic and laparoscopic treatment of obesityActa Endo (Buc) 2005 1(4): 453-461 doi: 10.4183/aeb.2005.453
AbstractToday therapeutic options for obesity include miniinvasive methods. The authors present the results of a prospective study regarding a lot of 224 obese patients treated between January 2003 ? January 2005 with laparoscopic adjustable gastric banding (LAGB) (n=184) and endogastric balloon (n=40). The medium body mass index (BMI) of admission for LAGB was 46.08 kg/m2 (extremes between 36 ? 71 kg/m2), 42 patients being super obese (BMI over 50 kg/m2). There were no conversions to open techniques. Postoperative evaluations were at 1, 6 and 12 months. Medium BMI was 39.1 kg/m2 (115 patients) at six months after surgery and 38.78 kg/m2 (59 patients) at one year after surgery. Comorbidities were remitted at 72% of patients at 6 months postsurgery. The patients treated with endogastric balloon endoscopically introduced (40 cases) were followed 6 months, after that they were extracted (26 cases). The medium BMI of admission was 33 kg/m2 (extremes between 21 ? 43 kg/m2) and at 6 months the medium BMI was 26.8 kg/m2. Although we do not benefit of a long time follow-up, the favorable initial results allow us to state that miniinvasive techniques deserve an important place in the efforts of struggling against obesity and its consequences. -

Serum Testosterone, Free Testosterone Index and SHBG Concentration for Reduction of Metabolic Syndrome in Tehranian MenActa Endo (Buc) 2012 8(3): 453-466 doi: 10.4183/aeb.2012.453
AbstractBackground. Although androgen deficiency in men is associated with obesity, whether the deficiency is a consequence of the syndrome is still unclear. Aim. The aim of this study was to determine the association between low levels of sex hormones and development of the metabolic syndrome. Subjects and Methods. A total of 836 men, aged ≥ 20 years, participants of the Tehran Lipid Glucose Study, were assessed at baseline and after 6.5 years follow-up, based on both ATP III and IDF criteria for occurrence of metabolic syndrome. The association between serum total and free testosterone index and SHBG and metabolic syndrome was investigated using logistic regression models. Results. After 6.5 years of follow-up, the metabolic syndrome developed in 131 and 207 men based on ATP III and IDF criteria respectively. Multiple logistic regression analysis showed an inverse relationship for total testosterone in the lower tertile concentration, and serum triglycerides, according to both criteria mentioned (OR = 1.6; 95%CI 1.02-2.5). According to ATP III criteria, adjustment of waist circumference eliminated most of the correlations between total testosterone and metabolic syndrome (OR=1.34, 95% CI (0.8-2.3), while SHBG and free testosterone index were not significantly associated with the syndrome. According to IDF criteria, statistical adjustment of waist circumference eliminated most of the correlations between total testosterone and metabolic syndrome [(OR=1.45, 95% CI (0.9-2.3)], and adjustment with triglycerides eliminated all correlations between SHBG and metabolic syndrome (OR=1.5, 95% CI (0.9-2.5). Conclusions. Androgen deficiency may be related to poorly controlled serum triglycerides and increased waist circumference. -

Thyroid Surgery, IONM and Sugammadex Sodium Relationships: Benefits in Sugammadex Sodium Use for IONMActa Endo (Buc) 2019 15(4): 454-459 doi: 10.4183/aeb.2019.454
AbstractBackground. It is important to protect recurrent laryngeal nerve (RLN) during thyroid surgery. Thus, intraoperative neuromonitoring (IONM) has got popularity. But, the half life of neuromuscular blocking agents used has a reverse correlation with reliability and effectiveness of IONM. This study aimed to research the effect of Sugammadex Sodium, a specific nemuromuscular blocking agent antagonist, on nerve conduction and IONM. Materials and methods. Twenty patients who underwent thyroidectomy under IONM followed an enhanced NMB recovery protocol-rocuronium 0.6 mg/kg at anesthesia induction and sugammadex 2 mg/kg at the beginning of operation. To prevent laryngeal nerve injury during the surgical procedures, all patients underwent intraoperative monitoring. At the same time, the measurement of TOFWatch acceleromyograph of the adductor pollicis muscle response to ulnar nerve stimulation was performed; recovery was defined as a train-of-four (TOF) ratio ≥ 0.9. Age, sex, recurrent laryngeal nerve transmission speeds prior to and after operation, BMI, duration of surgery, the change in nerve transmission after drug administration and complications were analyzed. Results. The mean age and the mean BMI were 47.6±11.82 years and 28.74±3.20, respectively. The mean operation duration was 52.65±5.51 minutes. There was no difference in either right or left RLN monitoring values before and after surgery. Following the drug injection, the TOF guard measurements on the 1st, 2nd, 3rd and 4th minutes were 23.5±4.90; 69.5±6.86; 88±4.1 and 135.9±10.62, respectively. Conclusion. Neuromuscular blocking antagonist use and monitoring nerve transmission speed with TOFguard can provide a safer resection.
