ACTA ENDOCRINOLOGICA (BUC)

Objective. Opium is a narcotic drug that is commonly abused. The prescription of pharmaceutical derivatives of opium is limited due to their possible harmful effects on the body’s metabolism and tolerability by patients. The aim of the present study was to evaluate the effects of chronic opium consumption on some sexual and thyroid hormones in diabetic and non-diabetic male and female rats. Material and Methods. This experimental study was conducted on 56 Wistar rats. The animals were divided into diabetic addicted (DA), diabetic non-addicted (DNA), non-diabetic addicted (NDA) and non-diabetic non-addicted (NDNA) groups of male and female rats. Peripheral blood samples were collected to measure the thyroid and sex hormone levels. Student’s t-test was used to compare the mean values of the hormones between two groups. Results. T3 serum level in male addicted groups significantly increased in comparison with non-addicted ones in both diabetic and non-diabetic groups. The testosterone level of male rats decreased due to the consumption of opium while it was significantly increased in diabetic and NDNA female rats in comparison with non-addicts. In DNA female animals, the mean level of 17-hydroxyprogesterone increased significantly compared with non-diabetic groups, however, it decreased in addicted females (diabetic and non-diabetic) in comparison with non-addicts. The level of DHEA-S increased significantly in diabetic and NDA male rats as compared with the non-addicted group. Conclusion. Opium affects the endocrine system in a sex-dependent manner, and opium could have different effects in diabetic and non-diabetic conditions.

Background. Postoperative hypocalcemia after thyroid surgery has a high prevalence ( 16-55% in different series). Incidental parathyroidectomy (IP) is a less discussed complication of thyroidectomy with consequences not properly defined. The aim of our study was to find incidence, risk factors and how to prevent IP. Methods. Extensive search of English literature publications via PubMed was performed and 73 papers from 1980 to 2017 were analysed using the GRADE system/classification, quality of evidence was classified as “strong” when the result is highly unlikely to change existing recommendation and “weak” when opposite. Results. Incidence of IP is 3.7-24.9%, while prevalence of permanent hypoparathyroidism is less frequent 6-12%. Direct relation between IP and hypoparathyroidism/ hypocalcemia remains controversial. Female patients, ectopic parathyroids, small thyroids, Graves’, malignancy, redo surgeries and total thyroidectomy favour IP. Routine visualization of parathyroids, new hemostatic devices, magnifying instruments and fluorescence can prevent incidental removal of parathyroids. Incidence of IP during videoassisted or robotic thyroidectomies was similar to open procedures. High volume, experienced and younger surgeons have lower complication rates (including hypoparathyroidism). Conclusions. Incidental parathyroidectomy is more frequent than we might have expected. It should be avoided and parathyroid glands should be kept in situ. Majority of studies are retrospective (low degree of evidence according to previous mentioned GRADE classification) and further meta-analysis or randomized control studies are welcome in order to define the impact of incidental removal of parathyroids on postoperative outcome.

Context. We report the use of subcutaneous somatostatin injection three times a day to decrease hypercortisolism in a patient who had Cushing’s syndrome induced by bronchial carcinoid tumour progressive pneumonia due to immune suppression. Subject and Method. A 46-yearold man with 7-month history of DM type-2, hypertension and cerebrovasculardisease, vertebral compression-fracture was admitted to our clinic. Physical examination was consistent with Cushing’s syndrome. Laboratory results revealed hyperglycemia (143 mg/dL; reference range, <100 mg/dL) and hypokalemia (2.29 mEq/L; reference range, 3.5-5.1 mEq/L). His morning serum cortisol was 40 μg/dL (reference range 6.7- 22.6 μg/dL), urine cortisol-excretion was 2245 μg/24 hours (reference range 58-403 μg/24 hours), after 1 mg dexamethasonesuppression test serum cortisol was 28 μg/dL (6.7-22.6 μg/dL) and ACTH 354 pg/mL (reference range 7.9-66 pg/mL). Adrenal CT and hypophyseal MRI were normal. An ectopic source was searched for Cushing’s syndrome. Chest CT scan of the right lung showed 12x9 mm nodule. High fever cough occurred on the followp. Chest radiograph revealed diffuse pneumonic infiltration. Despite 3-drug antibiotic combination therapy, infection did not improve. Subcutaneous injection of octreotide 3x100 μ/g was initiated to decrease hypercortisolism. The infection improved rapidly after the therapy. The morning serum cortisol, urine cortisol-excretion, ACTH was at the upper normal range (77.1 pg/mL, reference range 7.9-66 pg/mL) on 10th day of treatment. The patient was a consulted for surgery and the nodule was excised. The pathology was consistent carcinoid tumor. Conclusion. Subcutaneous octreotide treatment may be helpful to gain time for exploring the focus in ectopic cushing’s syndrome and to control the serious infections due to hypercortisolism.

There is limited information on the long-term natural history of adrenal function in adrenal hemorrhage following sepsis. The 19-year history of a patient is described who suffered adrenal hemorrhage during pneumococcal sepsis. Adrenal reserve using Cosyntropin testing with the 250 mcg dose was evaluated at seven time points during this interval, and a close observation of the patient enabled clinical correlation with adrenal status. The cosyntropin testing showed a 60 minute cortisol level post-hemorrhage of: 303.4 nmol/L (11.0 mcg/dL), one month; 656.6 nmol/L (23.8 mcg/ dL), 1 year 10 months; and 714.5 nmol/L (25.9 mcg/dL), 19 years. Over the years the patient experienced hypoadrenal symptoms requiring both hydrocortisone and fludrocortisone until her adrenal function consistently demonstrated a 60 minute cortisol level of ~ 717.3 nmol/L (26 mcg/ dL). Adrenal calcifications were visualized by ultrasound imaging and ultimately resolved. In conclusion, the patient’s hypothalamic-pituitary-adrenal system appeared to have ultimately restored normal basal adrenal function 19 years after the initial hemorrhage, and the dynamic cosyntropin data indicate that normal adrenal function should not be assumed with a 60 minute cortisol level of 496.6 – 551.8 nmol/L (18 – 20 mcg/dL). Finally, mineralocorticoid as well as glucocorticoid may be important for improved mental acuity in primary hypoadrenalism.

Introduction. The published data showed the importance of metabolic control in preventing complications in metabolic syndrome (MS) and the role of nutritional medical therapy in glycemic control and in the control of dyslipidemia, hypertension, weight loss/normalization (in overweight or malnourished subjects). Objectives. This study follows the evolution of sarcopenic index (SI) and other clinical parameters (body mass index (BMI), homeostasis evaluation index (HOMA index)) correlated with MS after diet therapy or diet therapy combined with sports, in patients with MS. Patients and methods. Our research was conducted during 12 months, on 110 patients >18 years of age, with HOMA index>2, divided into three groups: control group (CG, N=20), diet therapy group (DTG, N=58), diet therapy and sports group (DTSG, N=32). HOMA index for insulin resistance was calculated as the product of resting plasma insulin (in microunits/milliliter) and plasma glucose (in millimoles/liter), divided by 22.5. SI was determined using BIA, as being the ratio between muscle mass and fat mass, measured in cm2 /m2 . Results. A significant decrease of BMI (p<0.05) in DTG (from 31.63 to 24.50) and DTSG (from 30.18 to 24.17) vs. CG was observed (Pearson coefficient r=0.281, p<0.001). Weight status changed significantly (p<0.05) in the high-risk patients. There was a significant decrease of HOMA index (p<0.05) in DTG (from 5.93 to 2.57), DTSG (from 3.93 to 2.23), and in CG an increase was observed (from 3.15 to 3.37). Conclusion. The best results in the prevention/ treatment of sarcopenia in MS patients were obtained for DTSG, which benefited from both the positive effect of diet and physical activity.

Context. Increased arterial stiffness is an independent risk factor of cardiovascular events in patients with diabetes mellitus (DM). Objective. We aimed to evaluate elastic properties of common carotid arteries (CCA) in patients with DM type 1 (T1DM) by means of ultrasonographically based technique – two-dimensional speckle tracking. Design. Case-control observational study. Subjects and Methods. Examination of both CCA was performed in 50 patients with T1DM. The mean age of patients was 36.1 (±11.9) years and duration of diabetes was 8.9 (±11.9) years. 28 controls (mean age 38.6 ± 10.8) were examined according to the same protocol. Strain and strain rate reflected arterial wall stiffness and intimamedia complex thickness (IMCT) indicate presence of morphological changes. Parameters were compared between groups and regression analysis was performed to predict determinants of evaluated parameters. Results. Patients with T1DM had significantly more elastic CCA arteries than the healthy control (mean strain [%]: 6.05 ± 2.55 vs. 5.19 ± 1.79, p=0.0295; mean strain rate [1/s]: 0.91 ± 0.33 vs. 0.78 ± 0.25, p= 0.0142; respectively), but no significant differences in IMCT were revealed (0.49mm ± 0.12mm vs. 0.49mm ± 0.10mm, p=0.9893; respectively). Women had significantly decreased strain parameters in comparison with men, although the difference in IMCT was not significant. Conclusions. Two-dimensional speckle tracing revealed increased elasticity of CCA in patients with T1DM with no deterioration of arterial wall.

Background. The COVID-19 pandemic hit the world in late 2019, and by 2020, everyone was affected. Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) belongs to the beta-coronavirus genre and uses the angiotensin-converting enzyme 2 (ACE2) receptor to penetrate cells. Thyroid cells are rich in such receptors. Therefore, this gland is frequently involved alongside other organs in the COVID-19 disease. Aim. To describe COVID-19 inflammation and, eventually, dysregulations of normal thyroid function in a case series of patients diagnosed in a tertiary endocrinology care centre. Patients and Methods. We described subacute thyroiditis cases related to COVID-19 infection or vaccination against SARS-CoV2 infection (clinical manifestations and evolution). We also reviewed the literature data regarding COVID-19 infection or vaccination implications in thyroid pathology. Results. The literature describes two types of thyroid involvement in SARS-CoV2 infection or vaccination: subacute thyroiditis (SAT) and non-thyroidal illness syndrome (NTIS). In our case series, 5 patients (3 males), aged 41-54 years, developed the classical clinical manifestation of SAT related to COVID-19 infection (3 patients, concomitantly to upper respiratory infection or a few weeks apart) or anti-SARS-CoV2 ARNm vaccination (1-2 weeks after the vaccine administration). Clinical, laboratory and imaging findings and the evolution (steroid anti-inflammatory treatment used in 4/5 cases) were unremarkable compared to other SAT etiologies. Conclusion. We found no differences between the ”typical” viral and post-COVID-19 SAT regarding clinical presentation, severity, response to treatment, and thyroid function alteration. The only remarkable difference is the association of SAT with anti-SARS-CoV2 ARNm vaccination

Context. Intraoperative parathyroid hormone (IO PTH) monitoring has determinative role in surgery for tertiary hyperparathyroidism (tHPT). Objective. We tried to find out whether the extent of surgery to be performed can be dedicated via IO PTH monitoring in tHPT. Design. Renal transplantation (RTX) recipients who had been operated and followed up because of tHPT between 9/2014 and 5/2021 at our institution were retrospectively analyzed. Subjects and Methods. We analyzed the preoperative and postoperative data of 41 patients with tHPT. Results. Considering IO PTH monitoring; 70% and more decrease of the hormone level leaded us favorable results (89% surgical success) regardless of the PTX method (p<0.05). We obtained the same surgical success rate (75%) in patients in whom monitoring was done and was not done. We observed high success ratios (100%) in the latter group via subtotal PTX and total PTX plus auto transplantation (AT) (p<0.05). Conclusions. In surgery for tHPT, IO PTH monitoring should be maintained. When we observe 70% or more decline in the hormone level, we can decide to finish the operation regardless of the surgical technique. If hormone level decrease is below 70%, we have to continue exploration.

Introduction. In our department the standard surgical procedure for multinodular\r\ngoiter used to be subtotal resection. Over the years, total thyroidectomy has progressively\r\nreplaced subtotal resections and is performed in most of our patients at present.\r\nPatients and Methods. In a prospective cohort, observational study, we assessed\r\nthe immediate surgical outcome in 742 consecutive patients with multinodular goiter\r\n(MNG), admitted for surgery and operated in our hospital. Of all patients, 664 were women\r\n(89.5%) and 78 men (11.5%), aged 15 to 85 years, mean (?SD) of 48 ?13.8 years. Pathology\r\nwas done on frozen and permanent sections. The complications directly related to surgery\r\nin subtotal thyroidectomy (STT) were compared to total thyroidectomy (TT) or near-total\r\nthyroidectomy (NTT) patients: temporary hypoparathyroidism, temporary RLN injury,\r\npermanent hypoparathyroidism and permanent RLN injury. The &#967;2 test (95% confidence\r\ninterval) was used and values of p<0.05 were considered significant.\r\nResults. There were no significant differences among the patients with SST for\r\nMNG, NTT or TT , and TT for recurrent MNG or completion thyroidectomy, with respect\r\nto temporary and permanent RLN injury. Significant differences were found for temporary\r\nhypoparathyroidism in STT for MNG (9 out of 361 patients, 2.45%) and NTT or TT for\r\nMNG (21 out of 266 cases, 7.89%) (p<0.01) and between STT for MNG (9 out of 361 cases,\r\n2.45%) and TT for recurrent MNG for completion thyroidectomy (8 out of 45 cases,\r\n17.77%) (p<0.01) and no difference between NTT or TT for MNG (21 out of 266 cases,\r\n7.89%) and TT for recurrent MNG or completion thyroidectomy (8 out of 45 cases, 17.77%)\r\n(p=0.11). We registered no permanent hypoparathyroidism in our patients.\r\nConclusions. Total thyroidectomy is now the preferred option for the management\r\nof patients with bilateral benign MNG. However, TT is associated with a considerable rate\r\nof complications, higher than of STT. In patients with bilateral MNG and no malignancy,\r\nSTT remains in our opinion, a valuable option.
