ACTA ENDOCRINOLOGICA (BUC)

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.

Aim is to evaluate atherosclerotic risk factors and carotid intima media thickness [CIMT] in offspring of type 2 Diabetes Mellitus [DM] patients with normal glucose tolerance. Methods. We evaluated 96 offspring of Type 2 DM patients and 39 healthy control who were in similar age, sex and body mass. We measured fasting blood glucose [FBG], postprandial blood glucose [PBG], insulin, uric acid, homocystein, fibrinogen, HOMA-IR, lipid profile, hsCRP, microalbuminuria, glycosylated hemoglobin A1c and CIMT by Doppler ultrasonography. Results. FBG was found higher in study group [p<0.001]. The HOMA-IR was 1.7±0.98 and 1.2±0.58 mg/dL x uUI/mL for study and control group, respectively [p=0.007]. TCholesterol, triglycerides, HDL-C, LDL-C and homocystein levels were not different. HsCRP and fibrinogen levels were higher in study group [p=0.014 and p=0.035, respectively]. Microalbuminuria levels were higher in study group but not significant [p=0.111]. CIMT in study group increased distinctively [p<0,001]. In regression analysis, being in study group causes a significant increase on the mean CIMT level by 0.057 mm [0.029-0.086] Conclusion. Our study demonstrated that various atherosclerotic risk factors are aggregated in offspring of Type 2 DM patients having NGT even before they develop glucose intolerance. Having a diabetic family alone might be effective in developing increased CIMT.

Iodine plays an important biochemical role in human organism; its insufficiency produces disturbances in the synthesis of thyroid hormones and increases the volume of the thyroid gland. Iodine deficiency in pregnant women has severe consequences on maternal\r\nbody and fetal development. The aim of this study was to determine the incidence of iodine deficiency in pregnant women from Cluj city and county. Urinary iodine levels were determined by the Sandell-Kolthoff method. A group of 100 pregnant women was studied. The results show a mean iodine concentration at the lower limit of the normal range (107.58 ? 91.16 &#956;g/L), not correlated with the period of pregnancy.

The most common cause of hypercalcemia is parathyroid hyperplasia and carcinoma. Tuberculosis(TB) and sarcoidosis are the most common granulomatous diseases of the parathyroid. We report a case of parathyroid adenoma that can mimic many lesions. A 46-year-old woman on continuous ambulatory peritoneal dialysis (CAPD) with symptoms and signs of hypercalcemia. Laboratory findings were consistent with tertiary hyperparathyroidism. She underwent elective parathyroidectomy due to high PTH values despite effective treatment including calcimimetics and vitamin D receptor activators. Subtotal thyroidectomy and three and a half of parathyroid adenomas were removed. Histopathological examination revealed features of parathyroid adenoma with granulomatosis infection that supports tuberculosis. In order to confirm the pathological findings, the PCR study was performed on the pathology specimens. After obtaining a negative result, the treatment was stopped. We have reported a case of parathyroid adenoma that mimicking tuberculosis.

We present a 18 year old phenotypic female patient who presented for primary amenorrhea. Pelvic ultrasound revealed a hypoplastic uterus and CT scan showed a hypoplastic right gonad and a left gonadal tumor with extrapelvic location. Karyotype was 46XY. Hormonal assessment indicated hypergonadotropic hypogonadism: FSH was 39.69 mUI/ml, estradiol was 28.07 pg/ml, testosterone was 0.17 ng/ml. DHEA level was high &#8211; 21 ng/ml. Gonadectomy was performed at 15 years and histologic examination diagnosed left gonadoblastoma and right teratoma in a dysgenetic gonad. The patient had a good postoperatory evolution. Menses were induced with estrogenic and then estroprogestogenic treatment. Plastic breast surgery was performed at 18 years. Establishing the genotypic sex in patients with primary amenorrhea represents a crucial step knowing that intersex disorders bearing Y chromosomal material have a high risk for gonadoblastoma and germ cell tumors.
