ACTA ENDOCRINOLOGICA (BUC)

Background. We know that mortality had increased in diabetic patients with COVID-19 pneumonia. The aim of this study was to compare the mortality and inflammation parameters difference in critically ill COVID-19 patients according to their admission HbA1c levels and diabetes mellitus status. Secondary aim was to evaluate the effect of the first week hyperglycemic episode frequency on mortality. Methods. Critically ill COVID-19 patients who were tested for HbA1c levels on ICU admission were analyzed retrospectively. Results. Of 218 COVID PCR(+) patients, 139 met the inclusion criteria in study period. The median age was 67[57-76] years and 55(40%) of them were female. Seventy-six (55%) of the patients required invasive mechanical ventilation (IMV). The IMV requirement was higher in diabetic patients (p=0.01). When the groups were compared in terms of inflammatory parameters no significant difference was found except for admission and first week’s highest fibrinogen levels (p=0.02 and p=0.03, respectively). In multivariate analysis, fibrinogen levels were not determined as a risk factor for mortality. Overall ICU mortality was 43% (60/139). In group-1 23(37%), in group-2 27(57%), and in group-3 10(34%) patients had died. There was no statistically significant difference between groups in terms of mortality (p=0.05). Records of 96(69%) patients revealed there were more than five glucose readings over 180mg/dL during the first week. Mortality was higher in patients with more frequently hyperglycemic recordings (p=0.03). Conclusions. There was no significant mortality and inflammatory parameters difference in patients with and without diabetes. However, more than five glucose readings over 180mg/dL during the first week were found with increased mortality.

Context. Health anxiety was rarely investigated in Type II Diabetes Mellitus (T2DM). Objectives. The present study examines the effect of health anxiety on glycemic control and evaluates factors associated with health anxiety in patients with T2DM according to HbA1c level. Design. Cross-sectional. Subjects and Methods. Socio Demographic Data Form (SDVF), Health Anxiety Inventory-Short Form(SHAI), The Hospital Anxiety and Depression Scale (HADS) were administered to 185 patients with Type II DM . Patients were divided into two groups according to HbA1 c level (HbA1c levels below 7 (Group 1, n=69) and above 7 (Group 2, n=185)). We analyzed prevalence of health anxiety, factors associated with health anxiety between poor and good glycemic control and evaluated of T2DM patients according to health anxiety scale scores. Results. SHAI scale scores were low in 52 (28%), intermediate in 58 (31.2%) and high in 76 (40.8%) of the patients. We found the severity of depressive symptoms was positively correlated with health anxiety in both groups. As a result of this study, there was a relationship between high education and low socioeconomic level, having a job, exercise and anxiety level and low SHAI score in T2DM patients. Depression, stressful life events in the last 6 months were related with high health anxiety. Although the level of health anxiety was not different between groups, low blood sugar levels were related with high health anxiety. Conclusions. This study found that the prevalence of health anxiety in T2DM patients was higher than expected irrespective to poor or good glycemic control, but level of health anxiety in patients with T2DM is not a good predictor for the HbA1c level.

Niemann-Pick disease (NPD), is a rare autosomal recessive lysosomal storage disorder. Niemann-Pick A and B are caused by homozygous or compound heterozygous mutations in the sphingomyelin phosphodiesterase-1 (SMPD1) gene on chromosome 11p15. Type B is panethnic, although its frequency is increased in Turkish, Arabic and North African populations. Clinical features vary significantly among patients. It is a rare condition and information about its management an outcome during pregnancy and labor is limited. Both maternal mortality and morbidity due to severe postpartum hemorrhage has been reported. We represent a case of successful pregnancy outcome in patient with NPD type B. Type of mutations in SMPD 1 gene and severity of disease before pregnancy can predict the prognosis of pregnancy.

Objective. Adrenal incidentaloma are lesions which are stated incidentally by imaging methods when there is no suspicion of any disease in adrenal gland. Inappropriate Jak2 signaling causes some solid and hematological malignancies. But the Jak2 mutation has not been previously evaluated with regard to adrenal tumors. In this study, we aimed to positivity of the Jak2 mutation in patients with non functioning adrenal incidentaloma (NFAI). Methods. 45 (38 female–7 male) patients, who were followed due to NFAI at Tepecik Training and Research Hospital, Department of Endocrinology and Internal Medicine between February 2014 and March 2015, and 45 (31 female–14 male) healthy controls were included in the study. Results. The average age was 54.02±11.7 years and 38 patients were female, 7 were men. All patients underwent the following analyses for excluding a functioning adrenal mass, overnight dexamethasone suppression test, 24 hour urinary metanephrine and normetanephrine, plasma aldosterone/ renin activity ratio. Jak2 mutation of the patients who were diagnosed as NFAI was all negative. Conclusion. We could not identify the JAK2 gene mutation positivity in any sample. Since other possible mechanisms may throw fresh light on the etiology of adrenal incidentaloma, further clinical studies are needed on this subject.

When the laboratory results are not compatible with the clinical features of the patient, the presence of assay interference should be considered. Patient and Methods. Here, we report a case of macro-thyroid stimulating hormone (macro-TSH) in a 31 yearold woman who had hypothyroidism due to thyroidectomy as well as discordant TSH levels with the clinical findings. Her TSH level was spuriously high with low levels of free T3 and T4 on levothyroxine treatment and she had only mild fatigue. To screen for the presence of interference, we performed TSH measurements in different platforms and serial dilution of the sample. Her rheumatoid factor was found to be negative. Results. The testing for heterophile blocking and non-specific anti TSH antibodies suggested lack of interference. We did further test for the clinical suspicion of interference and TSH decreased to 29.8 μIU/mL from 210.5 μIU/mL (recovery: 14.1%) after polyethylene glycol (PEG) precipitation indicating the existence of macro-TSH. After two months of increased dosage of levothyroxine, her TSH level was still very high (192.0 μIU/mL), but free T3 and free T4 increased to normal levels. PEG precipitation test was reperformed and TSH was decreased to 46.0 μIU/mL from 192.0 μIU/mL (recovery: 24.0 %). Her levothyroxine replacement dosage was not increased since free T3 and T4 levels were normal. Conclusions. If there is a suspicion for the discordant TSH level, the presence of macro-TSH by PEG precipitation should be investigated even though first step investigations for interference were found to be negative.

Context. Thyroid incidentaloma is a common disorder in endocrinology practice. Current literature regarding the risk of thyroid cancer in incidentalomas found in patients with non-thyroid cancer is limited. Objective. The aim of the present study was to investigate the frequency of thyroid malignancy in thyroid incidentalomas detected in patients with non-thyroid cancer. Design. Case control study. Subjects and Methods. The database of 287 thyroid nodules from 161 patients with a history of nonthyroid cancer followed between 2008 and 2014 were retrospectively evaluated. Results. From 287 thyroid nodules, 69.7 % had a benign final cytology. Thyroid cancer detected in one nodule while follicular neoplasia detected in 4 nodules, atypia of unknown significance (AUS) detected in 10 nodules, Hurthle cell neoplasia detected in 5 nodules and suspicious for malignancy detected in 6 nodules according to fine needle aspiration biopsy results. Metastasis of the non-thyroid cancer to the thyroid gland was detected in 4 nodules. Twenty seven nodules from 15 patients were removed with surgery. There were 3 malignant nodules found after surgery (1 papillary, 1 follicular and 1 medullary cancer). In addition to these three thyroid cancers, two patients with benign nodules had co-incidental thyroid cancer detected after surgery. Finally, 11.1 % of thyroid nodules which underwent thyroid surgery had malignant histopathology except for co-incidental and metastatic cancers. Conclusions. The frequency of thyroid malignancy seems not to be substantially increased in incidental thyroid nodules detected in patients with non-thyroid cancer when these patients were evaluated in nodule-based approach.

Tuberous sclerosis complex (TSC) is an inherited neurocutaneous disease characterized by multiple hamartomas in multiple organs. However, there is limited evidence about neuroendocrine tumors (NETs) in patients with TSC, and routine screening of NETs is not recommended in the guidelines. Insulinomas are also an extremely rare disease. According to our knowledge, we presented the 10th TSC patient diagnosed with insulinoma in the literature. Thirty-two years old male patient diagnosed with TSC at the age of 27 due to typical skin findings, renal angiomyolipoma, history of infantile seizures, and cranial involvement was referred to our clinic. The main symptoms of the patient were palpitations, diaphoresis, confusion, and symptoms were improved after consuming sugary foods. Seventy-two hours fasting test was performed, and a low glucose level at 41 mg/dl, a high insülin level at 21.65 μIU/mL, and a high C-peptide level at 7.04 ng/mL were found at the 8th hour. In addition, a 12x7 mm lesion in the pancreatic tail was detected in abdominal imaging. Ga-68 PET-CT (gallium-68 positron emission tomographycomputed tomography) detected an increased uptake of Ga-68 in the pancreatic tail. The patient underwent distal pancreatectomy, and pathological evaluation was consistent with an insulinoma. The patient’s symptoms improved postoperatively. Since in nearly all TSC cases, as in our case, neuropsychiatric abnormalities, such as epilepsy, are one of the main disease manifestations, and these symptoms may be confused with the clinical manifestations of hypoglycemia in insulinoma. Therefore, patients with newly developed neurological symptoms and behavioral defects should be evaluated in terms of insulinoma.

Objectives. Metabolic syndrome (MetS) is a cluster of metabolic abnormalities that is linked with increased circulating markers of oxidative stress and lowgrade inflammation. The link between inflammation and MetS is not yet fully understood. We aim to evaluate the relationship between the levels of pro and anti-inflammatory markers such as apolipoprotein A1 (Apo-A1), apolipoprotein B (Apo-B), interleukin (IL) 6, tumor necrosis factor alpha (TNF-α), fibrinogen and complement component 3 (C3) and adiponectin and MetS/MetS components. Methods. This study was a case-control study conducted in an outpatient internal medicine clinic of the Ondokuz Mayıs University Internal Medicine Department. A total of 108 subjects (59 female, 49 male) who were not under any dietary restrictions and older than 17 years were selected and divided into two groups (54 with MetS and 54 healthy controls). Results. Increased levels of IL-6, C3 and Apo-B/ Apo-A1 ratios and decreased levels of Apo-A1 and TNF-α (except in patients with hypertriglyceridemia) were detected in the MetS group. Apo-A1 and TNF-α exhibited decreased levels, and IL-6, fibrinogen, C3 and Apo-B levels and Apo-B/Apo-A1 ratios increased as higher numbers of MetS criteria were met in the total study group. Conclusions. We found that inflammatory marker levels were not affected by an increased number of MetS criteria met in the MetS group although these levels increased in the control group with higher numbers of MetS components. The presence of a high number of MetS components does not have an additive pro-inflammatory contribution for subjects already diagnosed with MetS.

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.

Background. Parathyromatosis is a rare clinical condition where hyperfunctioning parathyroid tissue is scattered in the neck and the mediastinum. It is difficult to diagnose and manage due to recurrent or persistent hyperparathyroidism. Case report. We present a peculiar case of hyperparathyroidism as the parathyroid tissue was in unusual location. Scintigraphy done revealed a lesion suspicious for ectopic parathyroid tissue in the retrosternum in a 58 years old female patient with primary hyperparathyroidism. No pathologic lesions were found on neck exploration, subsequently, sternotomy was performed and suspicious lesion removed but microscopic evaluation of the frozen section found no parathyroid tissue in the resected specimen. A decision to perform thymectomy and total resection of pericardial fatty tissue was made. Final histopathology revealed parathyromatosis and confirmed the first case of pericardial type 1 parathyromatosis. Conclusion. Long-term remission is rare in these patients, sometimes needing medical treatment and multiple surgeries. In this patient, there was no recurrence during the four years follow-up. In patients with no history of neck surgery, primary parathyromatosis should be considered in the differential diagnosis of hyperparathyroidism.
