ACTA ENDOCRINOLOGICA (BUC)

Purpose. Minimally invasive follicular thyroid carcinomas (MIFCs) are uncommon; literature offers limited guidance on their natural history and management. Starting January 2015 we measured circulating tumor cells (CTCs) in patients with MIFC (n=22) or benign thyroid tumors with follicular features (n=4). Methods. In a retrospective analysis, we assessed detectability of and serial changes in CTC, compared demographic/clinical differences between CTC-positive versus CTC-negative subgroups using Student’s t-test, and examined correlations between CTC status and serum thyroglobulin using Spearman’s test. CTCs were quantitated via immunomagnetic separation/microscopic inspection. Results. Thirteen patients (50%: 12/22 MIFC, 1/4 benign tumor) were initially CTC-positive; 3 remained CTC-positive in ≥1 subsequent measurement. CTC-positive patients had larger tumors and more frequent multifocality and vascular invasion versus CTC-negative patients (n=13). However, no tested variable differed significantly between the subgroups. After 17.2±10.5 months, neither subgroup showed evidence of disease. Significant correlation was absent (p ≥ 0.263) between CTC and Tg negativity (r = 0.243; n=13 evaluable) or initial CTC positivity and Tg positivity (r = -0.418; n=9 evaluable). Conclusions. In the studied settings, CTC measurement is feasible, has unclear clinical/outcome implications, but may provide different information versus thyroglobulin testing. Lengthier assessment is warranted in larger series.

Background. The purpose of this study was to explore the influencing factors of serum uric acid (SUA) level and related gene polymorphisms in the healthy population. Methods. A total of 346 healthy individuals screened from different areas in Shenyang City and 195 patients with high SUA levels were included. Results. The levels of TC (total cholesterol), HDL-C (high-density lipoprotein cholesterol), LDL-C (lowdensity lipoprotein cholesterol), TG (triglycerides), GLU (blood glucose) ALT (alanine aminotransferase), TBA (total bile acid), TBIL (total bilirubin), CR (creatinine) and CYSC (Cystatin C) were statistically different between the healthy and hyperuricemia population (P<0.05). However, there was no statistical difference in the UA level between the two groups (P>0.05). After adjusting for UA, TC, HDL-C, LDL-C, GLU, TBIL and CYSC, the additive and recessive models of rs2231142 were statistically significant in females (P<0.05). For males, haplotypes of A-C-A-A-G-G, A-CG- C-G-G and A-T-G-A-A-G had significant difference between the healthy and hyperuricemia population (P<0.05). For females, the haplotypes of A-C-G-C-G-G and A-T-A-CA- T had significant differences (P<0.05). Conclusion. The distributions of SLC2A9 (solute carrier family 2 and facilitated glucose transporter member 9), ABCG2 (ATP-binding cassette G2), GCKR (glucokinase regulatory protein), KCNQ1, IGFIR (Insulin-like growth factor-I receptor) and VEGFR (Vascular Endothelial Growth Factor Receptor) were balanced in the population in Shenyang City. The haplotypes of A-C-A-A-G-G, A-CG- C-G-G and A-T-G-A-A-G were the influencing factors of high SUA in the population in Shenyang City.

Aims. The aims of our study were to assess the prevalence of prostate tumors in patients with metabolic syndrome.\r\nMaterial and methods. Subjects were patients recruited from three medical centers in Bucharest, Romania. For this study we selected men over 45 years of age with metabolic syndrome. The anthropometric measurements included height, weight, waist circumference and hip circumference. We calculated the body mass index (BMI) and measured the\r\nblood pressure. Biochemical tests included fasting plasma glucose (FPG), HbA1c, total cholesterol (TC), TG, HDL-C, fasting plasma insulin (FPI), prostate-specific antigen (PSA)and free-PSA. The prostate gland volume was measured by transrectal ultrasound. The diagnosis of prostatic cancer was based on a positive finding of the histological\r\nexamination obtained from 14-core biopsy.\r\nResults. There was a high prevalence of prostate tumors (benign and malignant) - 82.85% (n=343). Prostate cancer was\r\ndiagnosed in 7.9% of patients (n=33) using DRE, PSA, free PSA/PSA ratio and TRUS. The prevalence of BHP was 74.9% (n=310). The results of the present study indicate that\r\nPSA detects a significant number of prostate tumors missed in DRE. The use of DRE, PSA and TRUS, in combination, provided the highest rate of detection of prostatic tumors in patients with metabolic syndrome without infectious diseases of the prostate.\r\nConclusions. The prevalence of prostatic tumors, prostate cancer and benign prostatic hyperplasia in metabolic syndrome patients is high. Due to its increased prevalence, the BPH can be considered as a feature of metabolic syndrome.

Insulinoma is the most common endocrine tumor of the pancreas. The diagnosis suspicion is usually based on clinical symptoms and is confirmed by biochemical tests. Because the majority of insulinomas have a small size, the real problem is the localization of these tumors before surgery. We present the diagnostic and therapy difficulties, the value of available imaging techniques as well as our experience in five consecutive insulinoma patients from our clinic.

Introduction. The prevalence of obesity has reached alarming levels in the European Union, including in Romania. Data on the prevalence of obesity is only available at the national populational level, but this may hide the increased levels in disadvantaged groups. The purpose of this study was to evaluate the prevalence of overweight and obesity in the Roma population in Southern Romania. Material and method. This cross-sectional, epidemiological, non-interventional study was conducted from March 2014 to May 2017 in several settlements from Calarasi County. Screening procedures included interviews about medical history, lifestyle, anthropometric and clinical measurements and fasting capillary glucose. Results. The study population consisted of 1120 adult subjects, of which 735 Roma. In Roma population group, the prevalence of underweight, normal weight, overweight and obesity was 4.5% (n=33), 25% (n=184), 25.3% (n=186) and 45.2% (n=332) respectively. In Romanian Caucasians group, the prevalence of underweight, normal weight, overweight and obesity was 2.3% (n=9), 20% (n=77), 33.8% (n=130) and 43.9% (n=169) respectively. Among the Romanian Caucasians significant predictors of obesity were a sedentary lifestyle and current smoking. The odds of being obese in Roma population were higher in sedentary lifestyle persons and lower in current smokers, with primary education, and in those living in rural settlements. The family history of obesity had a significant association with obesity only in Roma population. Conclusions. Our results confirm the need to implement prevention programs in high-risk populations due to the double burden of malnutrition, lack of medical education and preventive healthcare, low socio-economic level.

We present the case-report of a 56 years-old woman with hypothyroidism due to autoimmune thyroiditis. The family history was positive for biopsy proven celiac disease (CD) in her daughter. The patient declared gluten-containing diet and was completely asymptomatic regarding gastrointestinal tract. The serological screening for CD reflected an activity of the disease by the presence of antiendomysial antibodies (EMA). Consequently, an upper gastrointestinal endoscopy was performed and biopsy specimens were obtained. The standard histopathological examination was unremarkable for a defined CD. However, the results of immunohistological techniques showed intestinal IgA deposits compatible with early developing CD. In patients with family history of CD, even without any suggestive symptoms, high index of suspicion regarding CD should be kept even more in those associating other autoimmune disease.

Context. Urolithiasis and obesity are now public health problems with an increased incidence worldwide. Management of urolithiasis in patients with morbid obesity is usually associated with higher morbidity and mortality compared to non-obese patients. ESWL is a nonsurgical procedure for the treatment of lithiasis. In obese patients the ESWL efficacy is influenced by the skin-to-stone distance or poorer detection of the calculus because of the fatty tissue. Objective. To highlight the overweight or obese lithiasic patient profile that could be best treated by ESWL. Subjects and Methods. We evaluated ESWL results in 1393 patients with kidney or ureteral stones between 5 and 20 mm. They were divided into 4 groups according to the BMI: Group A-overweight (BMI=25-30 kg/ m2); Group B-grade I obesity (BMI=30-35 kg/m2); Group C-grade II obesity (BMI=35-40 kg/m2) and a control group of normal weight (BMI=18-25 kg/m2). Results. Patients with a higher BMI required a greater number of ESWL sessions. A statistically significant greater number of patients with a waist circumference of >102 cm required more than 2 SWL sessions (p=0.007). Location of the stones in the pelvic ureter had the highest rate of success for obese patients (p=0.00001). The ESWL success rate in overweight and obese patients can be negatively influenced by BMI, abdominal circumference over 102 cm, and hardness of calculi reflected in the radiopacity on KUB. Conclusions. In patients with grade II obesity, pyelocaliceal calculus and increased hardness, other urological alternatives to lithiasis should be considered from the beginning.

Objective. Although bariatric surgery including gastrectomy has recently emerged as a useful treatment for type 2 DM with obesity, it is not clear whether gastrectomy itself can have beneficial effects on glucose metabolism. Therefore, in this study, we investigated changes in blood glucose in patients with and without diabetes who underwent gastrectomy. Methods. From Jan 2010 to May 2014, 77 patients with diabetes and 77 patients without diabetes who underwent gastrectomy at Chonbuk National University Hospital, South Korea, were included. We compared fasting plasma glucose levels and HbA1c value before and after gastric surgery. Results. After gastrectomy, 59 patients (38.3%) showed reduced fasting plasma glucose levels at the 1 year point, and 80 patients (51.9%) exhibited reduced fasting plasma glucose at 3 years, irrespective of their diabetes status. Among 77 patients with diabetes, decreased fasting plasma glucose was observed in 22 (28.6%) and 46 patients (59.7%) 1 and 3 years after gastrectomy, respectively. In patients who exhibited reduced fasting plasma glucose after gastrectomy, the degree of reduced glucose was as follows: 56.4±48.5 vs 23.2±16.1 mg/dL after 1 year, 58.3±52.3 vs 18.4±13.7 mg/dL after 3 years, in DM and non-DM patient respectively. Conclusions. Although there was a significant drop in mean fasting glucose after gastrectomy, not all patients experienced a drop in fasting glucose. Gastrectomy did not show a consistent association with glucose reduction in patients with and without diabetes, and in about half of the patients, fasting plasma glucose levels increased after gastrectomy. Therefore, bariatric surgery including gastrectomy needs to be performed with care in diabetes, and glucose monitoring including oral glucose tolerance tests should be done for assessing or prediction of the glucose state after gastric surgery in non-DM patients.

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.

Context. Both human immunodeficiency virus (HIV) infection and hepatitis C virus (HCV) infection represent systemic diseases that may develop metabolic complications, thus HIV/HCV coinfection metabolic changes need to be depicted. Objective. We aimed to evaluate the body composition changes in patients with either HIV and HCV monoinfections or HIV/HCV coinfection. Methods. 123 young men divided into three groups: 41 with HIV/HCV coinfection, 42 with HIV-monoinfection, and 40 with HCV-monoinfection were evaluated for total and regional bone and soft tissue body composition assessments using a Dual-energy X-ray absorptiometry (DXA) and were compared with 40 healthy men with age and body mass index similar to the study groups. To detect sarcopenia, we calculated the appendicular limbs’ lean mass index (ALMI), for obesity, we used the percent of body fat, and for lipodystrophy, we calculated the trunk/limbs index. Results. HIV/HCV coinfection is associated with a significant higher bone demineralization in all regions of interest compared to HCV or HIV monoinfections and to controls. The prevalence of bone demineralization in HIV/ HCV patients was 31.7%, more frequently at lumbar spine. Fat mass and lean mass were significantly lower in HIV/ HCV-coinfected patients than in controls. Lipodystrophy was found in similar percentages in all three evaluated groups (80.4% in HIV/HCV, 92.5% in HIV, and 95% in the HCV group). Sarcopenia was higher in HIV/HCV group (43.9%) and important in HCV-monoinfection group (30%). Conclusions. HIV/HCV-coinfected patients had the highest prevalence of bone demineralization, fat mass, and lean mass loss, compared to controls and to HIV and HCV monoinfections.
