ACTA ENDOCRINOLOGICA (BUC)

Context. Patients with Cushing’s syndrome (CS) of any etiology experience a number of physical and psychological symptoms which impact negatively on healthrelated quality of life (HRQoL). Subjects and methods. HRQoL was measured using CushingQoL questionnaire. Results. The first part of our study was a crosssectional analysis of 141 patients with CS over a 10-year period. CushingQoL score was lower in pituitary CS compared to adrenal CS. Remission and older age were associated with better outcome on item 7 (physical appearance anxiety). In a multivariate regression analysis after adjustment for etiology, remission status, age, UFC, duration of hypercortisolism and presence of hypercortisolism-associated comorbidities the female gender was the only negative predictor associated with poorer outcome on each of the three scores. The presence of hypercortisolism-associated comorbidities independently predicted poorer outcome on the psychological and the global subscales. The second part of our research was a prospective study of 27 patients with adrenal adenoma. Achievement of remission independently predicted improvement of the total score of any patient. Conclusion. Studying in details and understanding the mechanisms of the impaired HRQoL in patients with CS is the only way to become aware of the problem and create methods that could help these patients.

Context. Children having gonadal tumors and disorder of sex differentiation (DSD) are rare. Objective. To investigate the presentation of DSD children with malignant gonadal tumors. Methods. A retrospective study from 2010- 2020, that evaluated 17 children with DSD, including 13 females, eight months to 16 years, with congenital adrenal hyperplasia, 5-alpha reductase deficiency, androgen insensitivity syndrome, Turner, Sywer, and Klinefelter syndromes. Results. Ten children had malignant gonadal tumor; nine had germ cell tumors and one person granulosa cell tumors, while seven children with non-malignant tumor had gonadoblastoma, cystadenoma (five children), and cysts. Systemic malformations, obesity, elevated tumor markers, and psychosocial issues were observed in 90%, 90%, 70%, and 50% of children with malignancy unlike 28.6%, 42.9%, 14.35%, and 57.1% children without malignancy respectively. Most (9/10) children >12 years, had psychosocial issues, unlike 0/7 children ≤12 years. From 8/17 children presenting with symptoms suggestive of tumor, 75% had malignancy, while from 9/17 children with DSD presentation, 44% had malignant tumors. Malignancy was observed in 3/10 children between eight months to age six, while 7/10 children had stage 1-2 tumors. We reported a child, identified as female, aged 13 years, with partial androgen insensivity syndrome (PAIS) 46,XY, and testicular papillary serous cystadenoma with genomic variant AR NM_000044.4:c.2750del. p.(F917Sfs*27) chromosome Xq12, never published in people with PAIS nor population databases (GnomAD). Conclusion. DSD diagnosis raises numerous challenges. People with DSD have increased risk of malignancy, especially when obesity and, systemic malformations are present; also, psychosocial issues in these children are associated with postpubertal age.

Context. The metabolic syndrome is a profound, systemic impairment of the metabolism of lipids, carbohydrates and branched amino-acids, affecting specially obese people. Recently, many studies outlined the presence of the metabolic syndrome, also in non obese persons. Objective and design. To assess the relationship between insulin resistance and the cardiovascular component of the metabolic syndrome in a group of young, non obese subjects using a cross sectional study. Subjects and methods. We enrolled 103 subjects with body mass index < 30 Kg/m2, without metabolic syndrome to whom fasting glucose, triglycerides, high density lipoprotein cholesterol, insulinemia, waist circumference and arterial pressure were recorded in a crosssectional approach. Insulin resistance was evaluated using the homeostasis model assessment for insulin (HOMA-IR) index. Statistic data processing included Pearson relation and multiple regression (backward method), using the SPSS version 21 software. Results. A significant relationship between waist circumference, diastolic blood pressure and HOMA-IR is found. High value of HOMA-IR (>2.6) was more frequently in men (p=0.011). The incidence of the 2 metabolic components mentioned above was higher in the high value HOMA-IR group: 33% vs. 7% in women and 50% vs. 4% in men. Multiple regression showed a strong correlation between HOMA-IR and waist circumference (p<0.001) and diastolic blood pressure (p=0.008) that was maintained inside the women group (p=0.016 and p=0.032, respectively). In men, HOMA-IR correlated with waist circumference (p=0.031). Conclusion. We found a significant interdependence between waist circumference, diastolic blood pressure and HOMA-IR. Based on our results, we consider that lifestyle intervention should start as soon as abnormal waist circumference is recorded.

Background. Hip fractures are a major issue of public health as they are responsible for high morbidity, excess mortality and costs. There are differences in Europe and worldwide in the incidence rates of hip fractures and time trends, in the context of the population aging. Ten years ago, we characterized the incidence of hip fracture in Romania using data from the national hospital discharge register. Objective. This is the first Romanian study to assess the hip fracture incidence rates over a period of 11 years, between 2008 and 2018. Subjects and Methods. This analysis is a nationwide retrospective study on hospitals reporting primary DRG data on hip fracture, using a rigorous definition with both diagnostic and surgical procedure codes. The population aged 40+ was stratified in 5-year intervals and both the crude incidence rates and the adjusted incidence rates of hip fracture using standardization on age for the 2018 reference population were calculated in women and men. Results. From 2008 to 2018, the number of hip fractures rose by 53 % in women (from 7513 to 11512) and 22.4 % in men (from 4266 to 5220). Meanwhile, the Romanian population over 40 years increased by 12.5% in women and 14.2% in men. The crude incidence rate rose by 36.2% in women and 7.2% in men and the age-standardized incidence rates by 27.4% in women and 6% in men. These increases are mostly based on 85+ age populations’ changes. Conclusions. In Romania, the hip fractures incidence continues to grow throughout an 11-year-period, especially in women, representing an increasing burden for our society.

Background. Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of advanced cancers. Antibodies directed against programmed cell death receptor 1 (PD-1) interrupt the ability of the cancerous cell to depress the immune system. Methods and results. We report three patients who developed different endocrine abnormalities after treatment with nivolumab, a monoclonal antibody directed against PD-1. First, we report a 76-year-old male presenting with generalized fat loss after treatment with nivolumab which predominantly affected his face and trunk. Second, we described the development of thyroiditis that presented with thyrotoxicosis and the expression of thyroid-stimulating hormone receptor antibodies (TRAb). Finally, we observed the emergence of adrenal insufficiency due to hypophysitis in another case. Conclusion. Although immune checkpoint inhibitors are an effective anticancer treatment modality, adverse effects are evident that can affect the endocrine system. These adverse events may relate to different endocrine systems that include the thyroid and pituitary glands. Also, acquired generalized lipodystrophy should be suspected in patients developing unusual fat loss after treatment with ICIs.

Introduction. Spontaneous intracranial hypotension (SIH) is defined by reduced CSF pressure without an identifiable cause, hallmarked by acute onset of severe postural headache. Overlapping clinical presentation, MRI appearance, laboratory findings and prevalent risk population, may lead to diagnostic challenges in distinguishing SIH from the more common pituitary adenoma apoplexy (PAA). Cardinal MRI characteristics of SIH may be overlooked if sellar region examination is not coupled with a comprehensive cranial MRI examination. Pituitary enlargement in SIH was described with increased prevalence, but mostly as an incidental observation in neuroradiological series, without detailed functional pituitary assessment or follow-up. Case report. A young female with SIH presented with an intra-suprasellar mass lesion, imitating PAA. Mildly affected pituitary function, absence of visual impairments, and favorable clinical course influenced the decision against urgent pituitary surgery. Subsequent MRI confirmed spontaneous regression in pituitary size in first 5 months, along with clinical, hormonal and perimetric stability. Her initial mild central hypocortisolism resolved spontaneously, while baseline and follow-up dynamic pituitary assessment revealed no other abnormalities. Subsequent 9 years of endocrinological and neuroradiological follow-up confirmed gradual spontaneous pituitary lesion reduction. Awareness is raised that SIH may constitute a diagnostic pitfall due to clinical, neuroradiologic and laboratory overlapping with PA apoplexy, potentially leading to unnecessary surgery.

Background. Glycogen synthase kinase.3β (GSK.3β) has an important role in several signaling pathway including Wnt signaling pathway. Recent evidence has shown that this pathway is involved in follicle development, ovulation and Corpus luteum formation. Aim. In this study we have investigated the effect of LiCl (as a GSK.3β inhibitor) on the ovulation and corpus luteum formation in rat. Materials and methods. Immature 23-day female rats were injected with PMSG (15 IU) to induce follicular development, followed 48h later by HCG (15IU) to induce ovulation. To inhibit GSK3β activity 250 mg/kg LiCl were administerted at the time of LiCl injection. The ovaries were removed at 1,4,8,12,24 h after LiCl treatment and prepared for histological studies. Results. Our results show that the number of preovulatory follicle in LiCl treatment rats was not increased compared with control group. The number of corpus luteum blood vessels were decreased in comparison with control group (p<0.05). Conclusions. These findings show that although LiCl does not inhibit ovulation, it disrupts blood vessel formation in the corpus luteum.

Primary Pigmented Micronodular Adrenal Disease is a rare cause of Cushing’s syndrome, typically observed in children and young adults. It is often associated with the Carney complex. A typical, subclinical, or cyclic Cushing's syndrome clinic can be seen clinically. Treatment options include bilateral-unilateral adrenalectomy or medical treatment. This case presentation aims to draw attention to a rare condition by presenting a patient diagnosed with isolated PPNAD unrelated to the Carney complex.

Context. Mealtime insulin bolus is traditionally administered before meals in children with type 1 diabetes (T1D). Controlled studies on the use of pre-and postprandial insulin bolus have shown variable results. There are no realworld studies on postprandial bolusing of insulin in young children with T1D. Methods. Children with T1D aged <7 years were grouped into preprandial (Group 1) or postprandial (Group 2) groups according to the practice of prandial insulin use. Their retrospective data on mean glycosylated hemoglobin (HbA1c), hypoglycemic events, and diabetic ketoacidosis (DKA) episodes were compared. Results. Forty-four children (mean age 4.1±1.3 years, range 2-7 years) with mean diabetes duration of 2.0±0.7 years (range, 1-4 years) were identified; 23 (52.3%) belonged to Group 1 and 21 (47.7%) to Group 2. There were no differences in the mean HbA1c levels, mean hypoglycemic events, and DKA episodes between the two groups during a mean follow-up duration of two years. Conclusion. Young children with T1D administered insulin bolus during or immediately after meals showed similar long-term glycemic control and diabetesrelated adverse event profile compared to the premeal timing of insulin bolus. Larger real-world studies are needed on flexible insulin bolus timing in young children with T1D.

Background. The involvement of IGF 1 in renal pathophysiology has been studied in many details in type 1 diabetes but the role of IGF 1 in early nephropathy in patients with type 2 diabetes is less well characteristic. Objective. To determine whether serum IGF1 and GFBP-1 levels were different between patients with and without diabetic nephropathy and also to investigate the association between them and insulin resistance. Subjects and methods. Insulin resistance (HOMA-IR), IGF 1 and IGFBP-1 were measured in 20 type 2 diabetic patients with nephropathy, 20 type 2 diabetic patients without nephropathy and 15 control subjects. Results. Serum IGF 1 in diabetic nephropathy (333.3 +/-16.44 ng/mL) was significantly higher than in both diabetic patients without nephropathy (133.16 +/- 3.43 ng/mL) and in control subjects (174.33+/-6.23) (P <0.001). A significant negative correlation was observed between IGF 1 and HOMA, (r = -0.72) in diabetic patients without nephropathy and a positive correlation in diabetic nephropathy patients (r = 0.49). Conclusion. High IGF 1 and insulin levels in diabetic nephropathy patients in addition to the significant positive association between IGF 1 and HOMA suggest that both IGF 1 and insulin resistance may play major role in early renal changes in type 2 diabetes.
