ACTA ENDOCRINOLOGICA (BUC)

Objective. Medical Nutrition Therapy (MNT) is important in the treatment and regulation of diabetic patients. In this study, it was aimed to evaluate the effects of medical nutrition therapy on Pentraxin-3, hsCRP and body composition analysis in Type 2 diabetes patients (DM). Methods. This study included 160 individuals who were admitted and diagnosed with Type 2 DM. Laboratory, clinical, anthropometric and body composition parameters were obtained 3 months after baseline evaluation of the patients and the MNT was given by the dietitian. Results. After 3 months MNT, weight, body mass index, waist circumference, body fat weight, body fat ratio and visceral fat area (p<0.001), glucose (p<0.001), insulin (p=0.033), HOMA index (p=0.004), HbA1c (p<0.001), total cholesterol (p=0.001), LDL (p=0.008), ALT (p<0.001) and hsCRP (p<0.001) levels were significantly lower than they were before MNT. There wasn’t significant difference in triglyceride (p=0.509), HDL (p=0.079), Pentraxin-3 (p=0.706) levels and waist-to-hip ratio (p=0.802). The level of Framingham risk score after MNT was significantly lower (p<0.001). Conclusion. In this study, it was cocluded that MNT, applied to patients with Type 2 DM decreased cardiovascular risk and inflammation, contributed to the maintenance of glycemic control, and a significantly improved the body composition.

Context. In patients undergoing thyroidectomy for malignant disease, lower quality of life scores were observed in the early postoperative period compared to those undergoing thyroidectomy for benign causes. Objective. Thyroid gland diseases are commonly encountered in society. This study presents health-related quality of life differences in thyroidectomies performed for benign and malignant diseases and the factors affecting this. Design. Patients who underwent thyroidectomy for thyroid disease between January 2021 and January 2022 were evaluated prospectively. Subjects and Methods. The SF 36 questionnaire was applied and interpreted at the 1st and 6th months after thyroidectomy in patients over the age of 18 who did not have a history of previous thyroid surgery. Results. The study included a total of 228 patients. Among them, 171 (75%) were female (male/female: 57/171). Multinodular goiter in benign cases and papillary carcinoma in malignant cases were predominant (68.3% and 90.6%, respectively). SF-36 scores were found to be worse in the malignant group. Conclusion. In patients undergoing thyroidectomy for malignant disease, lower quality of life scores were observed in the early postoperative period compared to those undergoing thyroidectomy for benign causes.

Context. Follicular thyroid carcinomas (FTC) represent 6-10 % of all thyroid carcinomas; the evolution of FTC is quite controversial, partly due to frequent changes of the histopathological definition (minimally invasive–MIFTC or widely invasive carcinoma–WIFTC) and treatment strategies adjustments. Objective. This research aims to examine the diagnostic procedure, therapeutic attitude and survival rates of patients with FTC, over a period of 16 years in the same institution, with a follow-up of at least 4 years, by analyzing correlations between histology subtype, treatments and the rate of recurrent disease. Subjects and methods. We have studied 5891 patients with thyroid carcinomas who have undergone surgical or oncological treatment within the institution, between 1st January 2000 – 31st December 2015; among them we found 133 patients (2.25%) with “pure” follicular thyroid carcinoma: 114 (86%) women and 19 (14%) men, with a female-male ratio of 6:1. The age of the patients ranged from 10 to 76 years, with an average of 47.8 years. Statistical analysis was done comparing differences among groups of MIFTC and WIFTC. Results. There was an unexpected high percentage of WIFTC and also an increased number of biochemically persistent and/or recurrent disease in patients with MIFTC. A stronger correlation was observed with the tumour dimensions, rather than with the histopathological subtype. Conclusions. This research observed that overall survival was associated with tumour size rather than histopathological subtype and there is an important need to perform further studies to assess the effectiveness of treatment strategies.

Renal osteodystrophy and low bone mass are frequently found in patients with end-stage renal disease (ESRD). Our aim was to identify the independent predictors of age - and sex-adjusted bone mineral density (BMD), measured at different traditional sites, in patients with ESRD treated by hemodialysis (HD) or peritoneal dialysis (PD). Patients and Methods. We consecutively assessed 23 patients with ESRD (17 on HD and 6 on PD). Patients treated with 1,25 dihydroxyvitamin D, vitamin D derivates (paricalcitol) or calcimimetics were excluded. Serum parathormone and 25OH vitamin D were measured in all patients. In HD patients all biochemical measurements were done in the day between dialysis sesions. BMD was assessed at following sites: femoral neck, total proximal femur, 1/3 radius, ultradistal (UD) radius and total radius. Radial BMD was assessed in the forearm without arteriovenous fistula. BMD Z-score provided by the manufacturer was used. Results. In patiens undergoing PD the femoral neck BMD Z-score was significantly higher than in HD patients (difference -0.77 DS, 95% CI for difference -1.48 to -0.06). PTH correlated significantly with BMD Z-score at the 1/3 (r=-0.664, p<0.001) and total (r=-0.583, p=0.002) radius levels. Total proximal femur and UD radius BMD Z-scores did not correlate with any of the proposed variables. Years of dialysis, 25OH vitamin D and body mass index did not correlate with BMD Z-score at any site. Conclusion. In patients with ESRD PTH correlates strongly with BMD Z-score at cortical sites. PD seems to be less harmful to BMD than HD.

Background/Aims. Growth hormone deficiency (GHD) in children and adolescents is managed with growth hormone (GH) therapy and aims to achieve optimal height development. However, treatment adherence can be poor, reducing the likelihood of a successful outcome. Adherence varies between geographic regions. This observational study assessed satisfaction and adherence to NutropinAq (somatropin, recombinant human GH) treatment in Romanian children with GHD. Methods. Patients ≥3 years of age with GHD for which GH replacement therapy with NutropinAq had been initiated were recruited from 13 centres in Romania (protocol number: A-38-58035-016). The primary variable was patient/caregiver-reported treatment adherence (assessed at 3, 6 and 12 months on a 5-item Likert scale), secondary variables included treatment satisfaction assessed by the treating physician and patient/caregiver on a 5-point scale. Results. Most patients did not miss any treatment injections in any 3-month period between assessments (≥79.8% of patients were 100% compliant). The incidence of missed injections was higher among patients <7 years of age than older children, but no differences between genders was observed. At study end, 94.3% of patients/caregivers and 94.3% of physicians reported complete satisfaction with treatment. Conclusions. Overall treatment adherence to NutropinAq was high in the Romanian GHD paediatric population, and a high level of treatment satisfaction was reported by patients/caregivers. This suggests reliable treatment outcomes can be anticipated in this population.

Context. It is a challenge to determine the origin of Cushing syndrome (CS), especially in patients with low-normal adrenocorticotropic hormone (ACTH) concentrations. Objective. To evaluate the reliability of the corticotropin-releasing hormone (CRH) stimulation test in patients with CS whose origin of disease was not clearly identified using ACTH values, the high-dose dexamethasone suppression test (HDDST), and imaging in a single tertiary referral center. Design and Methods. Twenty-one patients with CS who were admitted to the endocrinology-metabolism clinic between 2004 and 2016 whose ACTH concentrations were 5-20 pg/mL and needed CRH stimulation test were retrospectively assessed. Results. Nine out of 21 patients were diagnosed as having Cushing’s disease (CD) and 12/21 had adrenal CS. The CRH stimulation test had a sensitivity and specificity of 100% and 8%, and positive and negative predictive values of 100% and 45% according to the current diagnostic criteria, respectively. An increase in ACTH ≥115% at 15 minutes and cortisol ≥86% at 60 minutes after CRH were associated with the highest likelihood ratio. The sensitivity and specificity of ACTH was 67% and 83% (AUC=0.75±0.12, 95% CI: [0.5-0.9]; p=0.03), and for cortisol it was 75% and 78% (AUC=0.71±0.15, 95% CI: [0.5-0.9]; p=0.03). Cortisol suppression of more than 64% from basal level in the HDDST suggested CD with the highest likelihood ratio. When these cut-off values were used together, both tests were negative in the patients with CD. Conclusion. The CRH stimulation test has low specificity to localize CS in patients with ACTH concentrations of 5-20 pg/mL according to the current diagnostic criteria. Different diagnostic criteria may be used in the CRH stimulation test and also in the HDDST in this group of patients.

A 51 years old woman, diagnosed 23 years ago with acromegaly and non-insulin dependent diabetes mellitus, who denied radical treatment and took bromocriptine 2.5 - 7.5 mg/day sporadically and oral antidiabetic drugs, presented with chronic headaches, acromegalic features, bilateral temporal hemianopia, hypertension, hyperglycemia. Her pituitary function was normal (random serum growth hormone 2.5 - 2.8 ng/mL). The skull X-ray showed an enlarged sella turcica, with blurred multiple contour and an &#8222;egg-shell&#8221; calcification boarding the interior sellar floor. Cranial CT scan revealed a 1.7/0.7 cm intrasellar macrocalcification with a low-density core, lying on most of the sellar floor. In addition there were partial empty sella, asymmetrical optic chiasm, multiple cerebral,\r\nvascular and pineal microcalcifications, but no visible pituitary or tumor mass. Apoplexy within a previous large pituitary growth hormone-secreting tumor, followed by resorption and peripheral calcification, may have produced this rare case of pituitary stone associated with remission of acromegaly and sequelar visual field defect.

Background and aims. Differences in the composition of the species of microorganisms in the gut may predict the evolution toward obesity and diabetes mellitus. We carried out a systematic review of the studies dedicated to the role of gut microbiota in diabetes mellitus and obesity. Methods. A systematic literature search of electronic databases was performed, using the search syntax: “Gut microbiota and diabetes and obesity”; abstracts in English, with data about mechanisms of pathogenesis and treatment options by changing the gut composition were included (259 articles). Studies were excluded if they did not have an abstract, or they contained no data about the exact implication mechanism of microbiota. Results. There are differences regarding the composition of the gut microbiota in healthy people and type 2 diabetes mellitus patients; the later proved to have significantly decreased Clostridium components, and increased Lactobacillus and Bifidobacterium populations. The intestines of obese subjects are less rich in microbial genes, have a reduced amount of Bacteroidetes and an increased amount of Firmicutes. Fecal microbiota transplantation from obese subjects resulted in adoption of the donor somatotype. Early differences in gut microbiota composition (higher number of Bifidobacteria) function as diagnostic markers for the development of type 2 diabetes mellitus in high-risk patients. The gut endotoxins contribute to metabolic syndrome manifestation. Experimental studies with prebiotic showed lower levels of cytokines and antiobesity potential. Conclusion. Microbiota composition and its changes since childhood have an important role in the metabolic syndrome. Any intervention in order to prevent or treat obesity and diabetes mellitus should have as target the gut immune system.

Context. Incidentally discovered solid adrenal tumors must be evaluated from two points of view: the risk of malignancy and the secretory feature. Objective. Our aim was to evaluate the surgical technique option in relation with clinical and histopathologic features. Design. We performed a retrospective study that included patients with adrenal gland tumors. Subjects and methods. All patients were operated between 2012 and 2019 by the same surgical team in a single center. Results. The batch included 102 patients with adrenal tumors operated through open surgery (OS, n=41) and laparoscopic surgery (LS, n=61). Tumor localization was especially on the right adrenal gland (n=52, 50.98%). Primary origin of the adrenal gland tumors was in 82 cases (80.39%) and a metastatic origin in 16 cases. Average dimension for surgical resected tumors was 4.02 cm (0.9-12 cm) for the LS group as compared to 7.22 cm (1.3-19 cm) for OS group with a predominant type of surgery represented by adrenalectomy and a conversion rate of 2.94%. The hospital stay was 7.22 days (5-12 days) in the LS group versus 12.72 days (6-57 days) in OS group with significant differences (p<0.01). Also, the postoperative recovery was significantly different (6.5 days versus 2.62 days, p<0.01). Conclusion. Laparoscopic approach represents the gold standard in adrenal gland tumors less than five centimeters in size. Adrenalectomy is mostly performed by LS and adenoma is the most frequent histopathologic type, while pheochromocytoma is operated through OS. LS has a significantly reduced hospitalization and postoperative stay compared to OS.
