    Bilateral Adrenal Myelolipoma in a 46 XX DSD patient with Congenital Adrenal Hyperplasia due to 21-hydroxylase Deficiency. case report

    Acta Endo (Buc) 2013 9(1): 109-119 doi: 10.4183/aeb.2013.109

    Increased frequency of adrenal tumours and adrenal myelolipoma has been reported in patients with 21-hydroxylase deficiency (21-OHD). Adrenal myelolipoma is an uncommon, benign, biochemically non-functioning tumor and occasionally reported in association with endocrine disorders. Diagnosis of myelolipomas is based on imaging with ultrasonography, CT or MRI being effective in more than 90% of cases. We present a 34-year-old man with massive bilateral adrenal masses which was detected on computed tomography and was diagnosed as 21-hydroxylase deficiency (21-OHD) based on biochemical findings. Computerized tomography of the abdomen demonstrated bilaterally very low-density adrenal masses (16x28 mm on the right side and 91x88 and 33x30 mm on the left side) consistent with adrenal myelolipomas. Since myelolipomas are considered as benign tumors, he was not operated. Tumor size did not increase during two year follow-up periods. It is recommended to the physicians to be aware of increased frequency of benign adrenal tumors that occur frequently in patients with 21-OHD. Untreated CAH with prolonged excessive ACTH stimulation might contribute to the growth of adrenal masses. CAH should always be ruled out in incidentally detected adrenal masses to avoid unnecessary surgical procedures.

    Risk of Hypercalcemia in Elderly Patients with Hypervitaminosis D and Intoxication

    Acta Endo (Buc) 2021 17(2): 200-206 doi: 10.4183/aeb.2021.200

    Objective. We aimed to determine the risk of hypercalcemia in a geriatric population with very high dose levels of 25-hydroxy-vitamin D (25(OH)D). Patients and Method. This study was designed as a retrospective, cross-sectional two-center study for examining the elderly patients with very high 25(OH)D levels (>88ng/mL) between January 2014 and December 2019. After recruitment, subgroup analyses of the patients were performed based on their calcium and vitamin D levels. Results. A total of 81.101 elderly patients, who had been evaluated for their vitamin D levels, were screened. Of the 458 (0.6%) elderly patients with 25(OH)D>88 ng/ mL according to our criteria, 217 patients with complete data were accepted into our study. The median 25(OH)D level was 103.7ng/mL (min-max:88.2-275.9). Most of the elderly patients (86.6%) with very high 25(OH)D levels were normocalcemic. When patients with hypercalcemia were compared with normocalcemic group, no difference was observed in the levels of 25(OH)D, intact parathormone (iPTH), phosphorus, alkaline phosphatase (ALP), and their age. However, the PTH suppression rate was significantly higher in hypercalcemic group (p=0.005). Conclusion. The elderly patients with very high 25(OH)D levels would appear to be mostly normocalcemic whereas life-threatening hypercalcemia would also occur. Treatment and follow-up planning should be done according to the clinical guideline recommendations.

    Protective Effect of Nigella Sativa Oil on Myocardium in Streptozotocin Induced Diabetic Rats

    Acta Endo (Buc) 2019 15(3): 289-294 doi: 10.4183/aeb.2019.289

    Background. To evaluate the protective effect of Nigella sativa oil (NSO) on the myocardium in streptozotocin-induced diabetic rats. Materials and methods. Thirty-two 7–8-week-old female Wistar albino rats (300–350 g) were equally divided into 4 groups: nondiabetic untreated animals (control), diabetes mellitus (DM), NSO, and DM+NSO groups. For the induction of diabetes, 45 mg/kg streptozotocin was applied to the rats in the DM and DM+NSO groups as a single intraperitoneal dose. NSO (400 mg/kg) was orally administered through an intragastric catheter once a day over 21 days. Formalin-fixed, paraffin-embedded tissue sections of the myocardium were evaluated histopathologically and immunohistochemically. Results. Compared to the control, NSO, and DM+NSO groups, the myocardial tissue samples from the rats in the DM group had significantly higher myositis, hyaline degeneration, and Zenker’s necrosis. Moreover, the Bcl-2 expressions were significantly higher in the control, NSO, and DM+NSO groups than in the DM group. Conclusion. NSO has a protective effect on the myocardium of streptozotocin-induced diabetic rats, most likely via suppressing apoptosis.

    The Course of Autoimmune Thyroiditis in Women

    Acta Endo (Buc) 2021 17(4): 472-478 doi: 10.4183/aeb.2021.472

    Context. Although, many studies have been made on the clinical course of autoimmune thyroiditis, this study focused on women and the factors effecting the natural course such as Selenium. Objective. The study aimed to determine Hashimoto’s thyroiditis (HT) clinical course in adults and the factors that could affect it. Design. The study was in a retrospective manner between 2010-2018. Subjects and Methods. 101 patients with HT were followed for 60.7±32.7 months. Biochemical and ultrasonographic data were collected. We investigated whether the age at diagnosis, family history, smoking habits, levothyroxine replacement therapy, and serum selenium (Se) levels influenced the disease course. Results. No relationship was observed between age and thyroid functions, thyroid volumes (TV), and autoantibody (Ab) levels at diagnosis. Ab levels were irrelevant with TV, echogenicity, and nodularity at diagnosis. However, initial TSH levels were significantly associated with anti-TPO levels (p=0.028, r=0.218). In the untreated group, thyroid functions seemed to be stable. TV decreased significantly in both treated and untreated patients (p<0.001). The decrease in TV was significantly higher in the treatment group (p=0.002). In euthyroid and subclinical hypothyroid patients, levothyroxine therapy did not affect the decrease in TV. Ab levels remained stable in untreated patients, but anti-TPO levels significantly decreased in treated patients (p<0.001). Smoking seemed to increase only anti-Tg levels (p=0.009). Family history was not associated with any of the studied parameters. Serum Se level was negatively correlated only with thyroid echostructure and only in treated patients. TV showed a “Gaussian distribution” in all patients at the diagnosis and at the end, independent of levothyroxine treatment. Conclusions. Most euthyroid patients remained euthyroid during five years of follow-up. The decrease in TV was significantly prominent with LT4 treatment. Importantly, TV followed a normal distribution instead of the bimodal distribution that is classically described.

    Effectiveness of Unilateral Adrenalectomy in Bilateral Adrenal Incidentaloma Patients with Subclinical Hypercortisolemia

    Acta Endo (Buc) 2021 17(4): 479-485 doi: 10.4183/aeb.2021.479

    Objective. Unilateral adrenalectomy (UA) is an alternative for treatment in bilateral adrenal incidentaloma (AI) to avoid possible long-term risks of bilateral adrenalectomy. In this study, we aimed to evaluate the effectiveness of UA in bilateral AI patients with subclinical hypercortisolemia (SH). Method. A total of 35 patients were included in this study. The patients were divided into two groups; those who underwent UA (n=27) and patients without adrenalectomy (PWA) (n=8). Hormone tests related to cortisol mechanism were reviewed to analyze results at the time of diagnosis compared to the latest available results to figure out any changes in cortisol mechanism and determine whether SH has recovered or not. Results. Median age of PWA group were higher compared to UA group (p=0.03). Median duration of followup in groups were similar (p=0.3). In the PWA group, none of the patients recovered from hypercortisolemia during their follow-up. In UA group 92.6% of the patients went into remission, whereas during follow-up 3.3% had recurred and another 3.3% were found to have post-adrenalectomy persistent SH. Patients in UA group had lower final cortisol level following dexamethasone suppression (p=0.003) and higher final adrenocorticotrophic hormone (ACTH) levels (p=0.001) than patients in PWA group. In UA group, final basal cortisol level (p=0.009) and final cortisol level after 1 mg dexamethasone suppression test (DST) (p=0.004) were lower than corresponding levels at the time of diagnosis. Discussion. Our study demonstrates unilateral adrenalectomy targeting the side with the larger lesion is an effective approach to reduce excess cortisol levels in bilateral AI patients with SH.

    18f-Fluorodeoxyglucose PET/CT Can Be an Alternative Method to Assessment of Insulin Resistance

    Acta Endo (Buc) 2019 15(4): 539-543 doi: 10.4183/aeb.2019.539

    Background. Insulin resistance is routinely measured by homeostasis model assessment of insulin resistance (HOMA-IR).Positron emission tomography of 18F-fluorodeoxyglucose combined with computed tomography (18F-FDG PET/CT) is a valuable assessment tool for patients with cancer or staging tumors. 18F-FDG PET/CT imaging can also be utilised to detect the metabolic activity of glucose in the adipose tissue, liver and muscles. The aim of this study was to determine insulin sensitivity in the liver, muscle visceral adipose and subcutaneous adipose tissue separately via18F-FDG PET/CT. Materials and method. Sixty three adult patients who underwent whole body 18F-FDG PET/CT scanning for clinical purposes (diagnosis or staging of cancer) between July and August of 2016 were included in the study. Patients were divided into two groups according to their BMI (Group 1: BMI<25kg/m2, Group 2: BMI>25kg/ m2). HOMA-IR,fasting glucose,insulin, triglycerides, total cholesterol, HDL levels were measured. We calculated SUV as the tissue activity of the ROI (MBq/g)/(injected dose [MBq]/ body weight [g]) on PET images and measured the maximum SUVs (SUVmax) of visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT),liver and rectus muscle ROIs (2 cm). SUV corrected by blood glucose level (SUVgluc) was calculated as SUVmax×blood glucose level/100. Student-t test, Chi-square test and Pearson correlation test were used for statistical analysis. Results. Mean glucose,insulin,HOMA-IR levels of the group-2 were statistically higher than of group-1. Muscle SUVmax and liver SUVmax of group-1 were statistically higher than of group-2. Muscle SUVgluc of group-1 was statistically higher than of group-2. HOMA-IR was negatively correlated with both SUVmax(r=-0.340, p=0.01) and muscle SUVmax(r=-0.373, p=0.005) Conclusion. 18F-FDG PET/CT has shown that the muscle tissue maximum FDG uptake was lower in the insulin resistance group. Therefore, 18-FDG PET/CT could be a valuable tool for diagnosing insulin resistance.

    Long term addison disease associated with new onset minimal change disease

    Acta Endo (Buc) 2012 8(4): 633-638 doi: 10.4183/aeb.2012.633

    A 40-year-old woman has been followed up for 19 years by the\r\nendocrinology clinic with the diagnoses of Addison disease and primary hypothyroidism. During the most recent\r\nvisit of the patient, she complained about fatigue and malaise with pretibial edema. In albumin analysis: 2.2 gr/dL and 5.8 g/day proteinuria were detected. In terms of\r\nnephrotic syndrome etiology, renal biopsy was performed and it was considered as minimal change disease. The dose of 7.5\r\nmg/day methyl prednisolone was potentiated to a dose of 1mg/kg/day. During her control, the proteinuria did not regress and 150 mg/day cyclophosphamide was added to the treatment. During the control, her proteinuria regressed from 5.8 r/day to 1.95 mg/day.
