The Potential of Diethylhexyl - Phthalate and Genistein to Induce Testicular Change in Rat's OffspringActa Endo (Buc) 2017 13(4): 417-424 doi: 10.4183/aeb.2017.417
AbstractObjective. To study the effect of diethylhexyl phthalate (DEHP) alone or in combination with genistein (GEN) on the reproductive system of offspring rats, focus on the induction of reproductive outcomes. Method. 180 Wistar rats were divided in 6 groups (30 animals per group): DEHP 250 mg/kg/day group, DEHP 1000 mg/kg/day group, DEHP 2500 mg/kg/day group treated with DEHP 2500 mg/kg/day, DEHP (2500 mg/kg) + GEN (50 mg/kg) group, DEHP (2500 mg/kg) + GEN (500 mg/kg) group and control group treated with the same quantity of corn oil. The differences in sperm quality and reproductive organs were observed. Results. After DEHP administration we observed an increase in rat’s abestrus, metaestrus and all estrus cycle (P < 0.05), a decrease in rat testicle’s organ coefficient and relative energy of testis Sertoli cells and an increase in the early, late and total apoptotic rate of testicular Sertoli cells in a dose dependent manner (P < 0.05). When combine DEHP with GEN the sperm density, sperm quality, the cell activity rate and testis tissue’s changes will decrease compared with the group that receive only DEHP in a dose dependent manner. Conclusion. DEHP exposure induces cryptorchidism in offspring rats and this is aggravated by adding GEN. -

Central Macular Thickness in Diabetic Macular EdemaActa Endo (Buc) 2020 16(4): 417-425 doi: 10.4183/aeb.2020.417
AbstractContext. Retinal microvascular dysfunction differs in macular edema lesions in the two eyes of the same patient with diabetic retinopathy. Objective. To evaluate the relationship between central macular thickness (CMT) and metabolic/systemic factors including anthropometric and laboratory findings, in patients with regressed diabetic retinopathy and a history of pars plana vitrectomy (PPV) combined with internal limiting membrane peeling in one eye. Subjects and Methods. Forty-two eyes with PPV and the same patients’ fellow 42 eyes (without PPV) included this study. Fasting blood samples of these 42 diabetics were collected to study adiponectin levels and other routine parameters. Results. The average hemoglobinA1c value was 7.3±1.3%. CMT of the vitrectomized eyes were significantly correlated with atherogenic index of plasma, total cholesterol, low density lipoprotein cholesterol and uric acid (UA). On the other hand, CMT of the nonvitrectomized fellow eyes significantly correlated with glucose levels and diabetes duration. Adiponectin, adiponectin/body mass index, adiponectin/fibrinogen were found significantly higher in the subgroup with CMT≥300µm in the vitrectomized eyes (P<0.05). UA levels were higher in the subgroup with CMT≥300µm in the fellow (nonvitrectomized) eyes (P<0.05). Conclusions. Although there was no relationship between CMT and hemoglobinA1c values, CMT seemed to be affected by atherogenicity, prooxidant chemical alterations in the course of inflammation, so determination of adiponectin and UA levels may be suggested before surgery to predict the atherosclerotic damage and the postoperative CMT value. Vitrectomy performed at the proper time may be helpful in metabolic remodeling process of the retinal tissue along with life style changes, well control of diabetes, and intraocular treatments. -

Retinal Microcirculation Investigation in Type I and II Diabetic Patients Without Retinopathy Using an Adaptive Optics Retinal CameraActa Endo (Buc) 2019 15(4): 417-422 doi: 10.4183/aeb.2019.417
AbstractContext. State of art imaging techniques might be a useful tool to early detect the retinal vessels lesions in diabetes. Objective and design. This analytical observational study investigates the retinal microcirculation changes in type I and II diabetic patients without retinopathy using adaptive optics ophthalmoscopy (AOO) and optical coherence ophthalmoscopy angiography (OCTA). Subjects and methods. Fifty-five subjects were included in this study and were divided in three groups: type I diabetic group (n=16), type II diabetic group (n=19) and control group (n=20). An adaptive optics retinal camera was used to assess the parameters of the temporal superior retinal arterioles. Moreover, vessel density of the superficial capillary plexus across the parafoveal area was measured with OCT-A. All cases were investigated once, in a cross-sectional design. Results. Diabetic patients from both groups had a higher wall-to-lumen-ratio compared to the controls (p=0.01 and 0.01, respectively). Interestingly, no significant differences were found between the two diabetic groups (p=0.69). Moreover, the vessel density was smaller in the type I diabetic group than in the control group (p=0.001) Conclusion. AOO might be a useful tool to detect early retinal vascular changes in diabetes before any clinical signs and together with OCTA it might bring important information on the prognostic and pathophysiology of the disease. -

Prevalence and Characteristics of the Polycystic Ovarian Syndrome in Overweight and Obese Premenopausal WomenActa Endo (Buc) 2022 18(4): 417-423 doi: 10.4183/aeb.2022.417
AbstractContext. Polycystic ovarian syndrome (PCOS) is commonly associated with obesity, but the prevalence of the syndrome in obese patients is not well established. Objective. The present study aims to investigate the prevalence of PCOS among overweight and obese premenopausal women and to evaluate the possible associations between the syndrome and metabolic disturbances in obese patients. Methods. Medical records of all women referred to a single endocrine center because of obesity and/or metabolic disturbances during a three-year period were analyzed. A total of 262 overweight and obese patients of reproductive age were included in the retrospective study. Results. The overall prevalence of PCOS using the Rotterdam criteria in the group of overweight and obese women was 26%. The degree of obesity did not influence the PCOS prevalence. Women with PCOS had higher blood glucose and insulin levels after glucose load in comparison to other obese patients despite the younger age. Conclusions. PCOS is a common finding among obese women seeking endocrine help. The oral glucose tolerance test is an important tool for the early detection of carbohydrate disorders in women with the syndrome. Furthermore, screening for PCOS components might be justified in young obese women with pronounced insulin resistance or dysglycemia. -

Thyroid hormones and proinflamatory cytokines' profile in amiodarone-induced thyrotoxicosisActa Endo (Buc) 2007 3(4): 417-436 doi: 10.4183/aeb.2007.417
AbstractIn this study we aimed to assess amiodarone’s effects on thyroid hormones, C reactive protein (CRP), interleukin 6 (IL-6) and tumor necrosis factor (TNF-α) profile in amiodarone-induced thyrotoxicosis (AIT) and their relationship with arrhythmias. In 60 patients with AIT (29M/31F), aged 59.7 ? 1.5 years and 105 hyperthyroid patients (25M/80F), aged 59.4 ? 1 years, TSH, total T3, total T4, free T4 were measured by IRMA or microenzymatic immunoassay. In 11 AIT patients and 26 patients with common hyperthyroidism, without significant Graves’ ophthalmopathy, CRP, IL-6 and TNF-α were measured by chemiluminescent immunoassays. AIT patients showed significantly lower T3 levels (273.82 ? 18.76 ng/dL) as compared to common thyrotoxicosis (361.89 ? 13.47 ng/dL), p<0.001, while T4 and FT4 were similar. AIT patients showed similar CRP, IL-6 and TNF-α levels to common hyperthyroidism (10.22 ? 3.03 mg/L vs. 6.31 ? 2.33 mg/L, p=0.11, for CRP, 17.46 ? 13.09 pg/mL vs. 6.46 ? 1.14 pg/mL, p=0.65, for IL-6, and 9.9 ? 1.76 pg/mL vs. 12.85 ? 2.22 pg/mL, p=0.22, for TNF-α, respectively. Patients with arrhythmias (n=19) showed significantly higher CRP, IL-6 and TNF-α levels as compared to patients without arrhythmias (n= 18): 10.81 ? 3.35 mg/L vs. 3.96 ? 1.08 mg/L, p=0.05, for CRP, 15.15 ? 7.52 pg/mL vs. 4.02 ? 0.74 pg/mL, p=0.007 for IL-6, and 15.16 ? 3.33 pg/mL vs. 9.2 ? 0.82 pg/mL, p=0.037 for TNF-α. In conclusion, AIT showed a similar pattern of proinflammatory cytokines to common hyperthyroidism. Increased CRP, IL-6 and TNF-α are found only in patients with thyrotoxicosis associated with atrial fibrillation or other arrhythmias. -

Association between Low Bone Mineral Density, Metabolic Syndrome and Sex Steroids Deficiency in MenActa Endo (Buc) 2016 12(4): 418-422 doi: 10.4183/aeb.2016.418
AbstractObjective. To analyze the association between low bone mineral density (BMD), metabolic syndrome (MS) and sex hormones deficiency in men. Methods. We included in this retrospective study 199 men with osteoporosis or osteopenia and 167 men with normal BMD as controls, aged between 55-85 years old. Patients’ evaluation included: medical history and physical examination, X-ray of thoracic and lumbar spine, measuring BMD at hip and lumbar spine, serum glucose and lipid profile, serum levels of total testosterone (tT), free testosterone (fT) and estradiol (E2). Results. The results revealed a significant association between low BMD and MS (p=0.011). Vertebral fractures were more frequently associated with MS (p=0.041). Patients with MS had lower vertebral BMD (p=0.037) and lower E2 levels (p=0.024) compared with those without MS. In men with MS, E2 deficiency can predict the value of vertebral and hip BMD. fT deficiency can predict only the value of hip BMD. Conclusions. A significant association between MS, low BMD, vertebral fractures and sex steroids deficiency, in particular E2 and fT was found. The presence of MS and sex hormones deficit can predict the reduction of BMD. -

What is Before the Autoimmune Seroconversion in Type 1 Diabetes?Acta Endo (Buc) 2015 11(4): 419-424 doi: 10.4183/aeb.2015.419
AbstractIn the past years a high interest has been observed for understanding the early stages of type 1 diabetes. That interest has been stimulated by the failures of the various “preventive” approaches of the autoimmune mechanism operating in this phenotype, carried out in young diabetic patients, soon (several months) after the clinical onset of the disease. Unfortunately, the recent Statement of three scientific organisations from the USA proposed a reconsideration of the well-known classical stages, not going backward to know better the true early onset of the autoimmunity, but refining only the second part of the classical stages which are closer to the clinical onset of diabetes (when the β-cell mass/function is about 70% already irreversibly lost). In opposition with the above mentioned initiative, our effort has been devoted to the detection of earlier stages of diabetes which silently operate before the detection of the first islet autoantibodies (mainly proinsulin/insulin antibodies) which strangely was omitted in the new mentioned reclassification of preclinical stages of type 1 diabetes. -

Gender-Related Differences in the Practices and Attitudes of Early Detection in Rumanian Skin Cancer PatientsActa Endo (Buc) 2013 9(3): 419-428 doi: 10.4183/aeb.2013.419
AbstractContext. Advanced skin cancers have high mortality and morbidity, and early detection is crucial for prognosis. Information regarding the patterns of skin self-examination and tumor early detection in the Central and Eastern Europe is scarce. Objective. Analyze the gender differences in the practices and attitudes related to skin cancer early detection of skin cancer patients in Romania. Methods. Prospective questionnaire- based survey of patients with confirmed diagnosis of skin cancer, registered in a university reference center for dermatooncology between 2011-2012. Results. 122 skin cancer patients completed the survey (response rate 72%). Female skin cancer patients reported lower level of education and likelihood to receive a medical full skin examination. Women were more likely to check their own skin and to detect suspicious lesions on themselves and their partners than men. They delayed longer the presentation to a physician after noticing a suspicious lesion (11.4 months vs. 6.4 months median). 90.76% of all skin cancer patients were not warned by any doctor about their skin cancer risk; 30% of them never check their skin. Conclusions. Women tend to be more concerned about their skin than men, but receive less medical attention and delay longer the diagnosis. Our study also signaled an urgent need of improving the patients and physicians education for skin cancer early detection in Romania. -

Efficacy of radiotherapy in patients with gonadotropin-expressing pituitary tumor cells in non-functioning and GH-secreting adenomasActa Endo (Buc) 2006 2(4): 419-435 doi: 10.4183/aeb.2006.419
AbstractThis study evaluates the differences of radiotherapy in patients with pituitary tumors, in relation to gonadotropin immunoreactivit.\r\nDesign. It is a longitudinal, retrospective study of 117 patients submitted to pituitary surgery and high voltage radiotherapy. The excised tumors were 70 non-functioning adenomas (NFA) and 47 GH-secreting adenomas producing active acromegaly (ACM). They were evaluated before and after pituitary surgery, before radiotherapy as baseline, then at 3 different intervals at 0 - 2, 2 - 5 and > 5 years after baseline.\r\nMethods and patients. Computer tomography was used for measuring the tumor size and specific immunoassays were used for FSH, LH and nadir GH during 75 g oral glucose load. Immunohistochemistry (IHC) was performed with avidin-biotine method. High voltage conformational radiotherapy used a linear accelerator of 10 meV, with a 50 Gy on target tumor. For statistics, student’ t test was used. Data before surgery (tumor volume and hormonal sexretion) were available in 70 unselected patients (31 NFA and 39 ACM from the above group). Postsurgery we defined following groups: NFA-A1 exposed to radiotherapy (n=21) and NFA-C1 unexposed to radiotherapy (n=22); ACM-A2 exposed to radiotherapy (n=20) and ACM-C2 unexposed to radiotherapy (n=10).\r\nResults. Immunohistochemistry for NFA showed 27 immunopositive for FSH or/and LH (GD+) and 40 immunonegative for FSH and LH (GD-), 3 undetermined, while for ACM were 12 GD+, 33 GD-, 2 undetermined. Immunohistochemistry data on defined groups was as follows: NFA-A1 (n=21: 12 GD+, 9 GD-) and NFA-C1 (n=22: 6 GD+, 16 GD-); ACM-A2 (n=20: 4 GD+, 16 GD-) and ACM-C2 (n=10: 3 GD+, 7 GD-). In patients with NFA presented before therapy, there are not significant differences of tumor sizes or of the levels of FSH/LH between GD+ and GD- adenomas. In ACM, before any therapy, the GD+ patients showed a significantly higher FSH levels (20.7+11.4 U/L, n=6) than GD- patients (FSH 6.6+1.6 U/L, n=22, p< 0.05) and a nonsignificant lower serum GH levels (15.1+3.5 ng/mL, n=8 versus 33.5+8.9 ng/mL, n=30 p=0.06), although the tumor size was similar between the two groups. Radiotherapy upon NFA: GD+ adenomas did not decrease their volume after radiotherapy (cranio-caudal diameter 1.63+0.79 cm, before and 1.54+0.68 cm at 2 - 5 years post-radiotherapy n=6, p= NS), in contrast with GD- tumors in which a slightly, but significant decrement in volume could be demonstrated (from 2.79+0.53 cm to 2.43+0.31 cm at 2 - 5 years, n=5, p= 0.01). Radiotherapy in ACM resulted in a decrement of serum GH level and tumor size, as compared with the control group without radiotherapy. The effect was maximal at the interval of 2-5 years. The ACM, GD- tend to respond better to radiotherapy, (i.e. GH levels decreased from 15.1+5.4 to 6.6+2.4 ng/ml at 2-5 years, p=0.05), while in patients with ACM, GD+ the GH level did not show a significant decrease (serum GH was 7.3+3.3 ng/ml before and 5.1+4 ng/mL at 2-5 years post-radiotherapy, p = NS). The CC diameter of GD- decreased from 1.1+0.3 to 0.7+0.2 at 2-5 years, p=.059, while in GD+: from 1.64+0.4 to 1.2+0.3 ng/mL at 2-5 years, p = NS.\r\nConclusion. Pituitary adenomas, both NFA and ACM that contain gonadotropin immunoreactive cells tend to be more radioresistant than those without gonadotroph cells.
