The effect of mass functionality on laparoscopic adrenalectomy outcomes.

PURPOSE: This study aimed to determine the effect of adrenal mass functionality and different hormone subtypes synthesized by the adrenal masses on laparoscopic adrenalectomy (LA) outcomes. MATERIALS AND METHODS: The study included 298 patients, 154 of whom were diagnosed with nonfunctional masses. In the functional group, 33, 62, and 59 patients had Conn syndrome, Cushing's syndrome, and pheochromocytoma, respectively. The variables were analyzed between the functional and nonfunctional groups and then compared among functional masses through subgroup analysis. RESULTS: The incidence of diabetes mellitus, hypertension, and obesity, blood loss, and length of hospital stay (LOH) were significantly higher in the functional group than in the nonfunctional group. In the subgroup analysis, patients with pheochromocytoma had significantly lower body mass index but significantly higher mass size, blood loss, and LOH than the other two groups. A positive correlation was found between mass size and blood loss in patients with pheochromocytoma (p ≤ 0.001, r = 0.761). However, no significant difference in complications was found among the groups. CONCLUSIONS: In this study, patients with functional adrenal masses had higher comorbidity rates and American Society of Anesthesiologists scores. Moreover, blood loss and LOH were longer on patients with functional adrenal masses who underwent LA. Mass size, blood loss, and LOH in patients with pheochromocytoma were significantly longer than those in patients with other functional adrenal masses. Thus, mass functionality did not increase the complications.

Serological Screening for Celiac Disease and Gastrointestinal Absorption Disorders in Patients with Autoimmune Endocrine Diseases.

Celiac disease (CD) accompanying autoimmune endocrine diseases (AED) is generally asymptomatic. This study aimed to evaluate the frequency of clinically overt or silent CD in patients diagnosed with autoimmune endocrinopathy and the clinical effects of silent CD in these endocrinopathies. The study included 166 patients with known or newly diagnosed mono-/polyglandular AED and 90 age- and gender-matched healthy controls. The patients were classified into four groups: type 1 diabetes mellitus (DM) (n=44), Hashimoto's thyroiditis (HT) (n=68), Addison's disease (AD) (n=17), and autoimmune polyglandular syndrome (APS) (n=37). All subjects were serologically screened for tissue transglutaminase antibody (tTG) IgA and IgG. In addition, to evaluate the possible systemic consequences of CD, serum parathormone (PTH), 25-hydroxicholecalsiferol (25-OH-Vit D), vitamin B12, folic acid, iron, iron-binding capacity (IBC), and ferritin levels were measured. In the total series, 193 (75.4%) individuals were females, and 63 (24.6%) were males. TTG IgA antibody positivity was found in 23 among 166 patients, while no positivity was encountered in the healthy control group. The highest rates of positive tTg IgA frequency were detected in AD, with 29.4% (5/17). Serum 25-OH-Vit D, vitamin B12, folic acid, iron, and ferritin levels were significantly lower in AEDs compared to controls (p<0.001), and the lowest these parameters were detected in patients with AD. The serologic CD prevalence is higher in autoimmune mono-/and polyglandular endocrine diseases than in the control group. The data support recommends regular screening for CD in all patients with AEDs.

Urinary Neutrophil Gelatinase-Associated Lipocalin (NGAL) as a Marker of Diabetic Nephropathy in Type 1 Diabetic Patients.

BACKGROUND: Glomerular and tubulointerstitial damage plays a role in renal function failure in diabetic patients. While both serum and urine levels of neutrophil gelatinase-associated lipocalin (NGAL) show significantly increased levels in acute renal pathologies, the NGAL increase in active phase indicates a reversible condition in chronic cases. MATERIALS AND METHODS: 52 type 1 diabetic patients and 30 healthy volunteers participated in the study. The diabetic participants were separated into two groups as follows: a normoalbuminuria group consisting of those with an albumin/creatinine ratio less than 30 mg/g and an albuminuria group consisting of those with an albumin/ creatinine ratio equal or greater than 30 mg/g. Albumin, creatinine and NGAL were measured in all participants. RESULTS: Urinary NGAL median level was 21.1 ng/mL for diabetic patients and 11.9 ng/mL for healthy controls, and the difference between the two groups was statistically significant. When diabetic patients were compared as those with and without albuminuria, the median urinary NGAL levels of normoalbuminuria and albuminuria were 24.7 and 16.1 ng/mL, respectively, but the difference was not statistically significant. Statistically similar results were obtained through evaluation of the ratio of urinary NGAL excretion to creatinine excretion. The NGAL/Cr ratio was significantly higher in diabetic patients than in healthy controls, but no statistically significant difference was found between the diabetic patients with and without albuminuria. CONCLUSIONS: Urinary NGAL excretion in type 1 diabetic patients is found to be increased over a wide range, but it does not correlate with urinary albumin excretion. In this regard, urinary NGAL excretion should not be used as an alternative to microalbuminuria in detecting diabetic nephropathy. The greater amount of NGAL excretion among diabetic patients may be due to diabetic nephropathy with possible tubulointerstitial damage pathologies.

May hemocytometer parameters be a biomarker in distinguishing between adrenal adenomas and carcinomas and in prognosis of adrenocortical carcinomas?

Recently, studies have reported that inflammatory response and elevated platelet counts are associated with several cancers. In the present study, we aimed to evaluate hemocytometer parameters in differentiating adrenal adenoma and carcinoma, and the prognostic utility of hemocytometer parameters in adrenocortical carcinoma (ACC). We included 30 patients with nonfunctional adrenal adenoma and 13 patients with ACC having undergone surgery between 2005 and 2017 and followed up postoperatively at our centre. The neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), red blood cell distribution width (RDW), mean platelet volume (MPV) and plateletcrit (PCT) were evaluated preoperatively in all patients included in the study. There was a significant difference between the adrenal adenoma and ACC groups in terms of neutrophil and lymphocyte counts, NLR and PLR. There was no significant difference between the two groups in terms of platelet count and MPV, but PCT levels were significantly lower in ACC group. There was no statistically significant difference between recurrent and/or metastasis positive patients and negative ones according to NLR, PLR, RDW and MPV. There was a statistically significant difference in RDW levels and tumor diameter between the groups. Our study is the first to evaluate hemocytometer parameters in differentiating adrenal adenomas and carcinomas, and also in the prognosis of ACC. The present study suggested that the hemocytometer parameters may be a marker in the differential diagnosis of adrenal adenomas and carcinomas. However, our study also showed that these parameters had no prognostic value in ACC.

Cytokine signal suppressor (SOCS) 1-1478 CA/del gene polymorphism in Turkish patients with polycystic ovary syndrome.

Eighty-four subjects, premenopausal female patients (n = 42, mean (SD) age: 26.4 (4.2) years) diagnosed with polycystic ovary syndrome (PCOS) and age-matched healthy volunteers (n = 42, mean (SD) age: 27.6(3.4) years), were included in this study. Data on physical examination, anthropometric measurements and blood biochemistry analysis were recorded for each subject along with analysis for SOCS1-1478 CA/del polymorphism by polymerase chain reaction-restriction fragment length polymorphism. The relation of SOCS1-1478 CA/del polymorphism to PCOS status and insulin resistance was analysed via logistic regression analysis. Mean (SD) levels for BMI (28.5(6.5) vs.22.5 (4.9) kg/m2, p < .001), HOMA-IR (3.1(1.8) vs.1.5 (1.0), p < .001), LDL-cholesterol (115.9(32.7) vs.100.7 (27.3)mg/dL, p = .03) and triglyceride (113.8(64.9) vs.83.3(36.3)mg/dL, p = .017) were significantly higher in patients. Groups were similar in terms of SOCS1-1478 CA/del polymorphism. No significant relation of this polymorphism was noted to PCOS and HOMA-IR. Our findings revealed no difference between groups in terms of the rate of SOCS1-1478 CA/del polymorphism, and no significant relation of this polymorphism to insulin resistance and PCOS status. Impact statement Polycystic ovary syndrome (PCOS), the most common cause of anovulation and the most commonly encountered form of female endocrine disease. SOCS proteins have been suggested to play a fundamental role in the negative feedback regulation of the JAK-STAT pathway, which is the major signalling pathway involved in a wide range of physiologic and pathologic processes, including inflammatory diseases, malignancies and immune disorders. Pathways involving the induction of suppression of SOCS proteins were also shown likely to be involved in mediating cytokine-induced insulin resistance. The present study was designed to determine the frequency of SOCS1-1478 CA/del gene polymorphism in patients with PCOS in relation to healthy controls and insulin resistance. Our findings revealed significantly higher rates of insulin resistance, obesity and dyslipidaemia in Turkish patients with PCOS compared with age-matched healthy controls, while no difference between study groups in terms of the rate of SOCS1-1478 CA/del polymorphism along with no significant relation of SOCS1-1478 CA/del polymorphism to insulin resistance and PCOS status. Future larger scale studies with the application of standardised diagnostic methods and criteria, and of state-of-the-art modern techniques including genomics, proteomics and pharmacogenetics would provide better understanding of the association between PCOS and genomic variants.

Serum macroprolactin levels in pregnancy and association with thyroid autoimmunity.

BACGROUND: To assess the contribution of macroprolactin to high serum prolactin levels and their association with thyroid status and thyroid autoimmunity during pregnancy. METHODS: 138 pregnant women who suspected of having thyroid dysfunction were studied and divided into three groups according to the thyroid status; group 1; euthyroidism (n 40), group 2; hypothyroidism (n 54), and group 3; hyperthyroid (n 44). Polyethylene glycol (PEG) precipitation method was used for detection of macroprolactin. A percentage recovery of 40 % or less is considered as macroprolactinemia. If macroprolactin was negative, the percentage of monomeric prolactin recovery (monoPRL %) after PEG precipitation was used for comparison between the groups. RESULTS: Macroprolactinemia was found in two patients (1.4 %) one from hypothyroid and other from euthyroid group. Basal prolactin levels in these patients were 400 and 403 ng/mL respectively. Referring to all patients, there was no correlation between PRL, macroPRL or monoPRL % with thyroid hormone status and also with the serum levels of thyroid antibodies (p > 0.05). A positive correlation was observed between the serum levels of PRL with TSH (p = 0.014 and r = 0.219), while a negative correlation was found with FT4 (p = 0.011 and r = -0.227). CONCLUSIONS: Despite the fact that serum prolactin levels were found to be high during pregnancy, the contribution of macroprolactin was found to be insignificant in our study. Unlike other auto immune diseases, we could not find any relationship between thyroid autoimmunity and PRL, macroPRL or monoPRL %. These results confirmed that measured prolactin was quite homogeneous during pregnancy.

Relationship between glycemic control, microalbuminuria and cognitive functions in elderly type 2 diabetic patients.

AIM: The prevalence of diabetes is increasing in elderly populations, and is thought to be an important risk factor for cognitive dysfunction in this age group. METHODS: The study included 104 patients aged over 60 years who were followed-up for type 2 diabetes for at least 6 months, in addition to 44 controls. Glycemic parameters, microangiopathic complications, microalbumin elimination, and the Standardized Mini Mental State Examination (SMMSE) scores were used as indicators of cognitive function. RESULTS: The SMMSE scores of diabetic patients were significantly lower than the control group (p < 0.05). The average SMMSE score for normoalbuminuric diabetic patients was 22.36 ± 4.66, compared with 22.61 ± 4.90 for the microalbuminuria patients (p = 0.84). A positive correlation was found between SMMSE scores and patients' hemoglobin values and education levels, whereas a negative correlation was noted between SMMSE scores and systolic and diastolic blood pressures and hemoglobin A1c levels (p < 0.05). Patients with diabetic neuropathy, a microvascular complication of diabetes, were found to have significantly lower SMMSE scores (p = 0.011). CONCLUSION: Elderly diabetic patients showed decreased cognitive function compared to volunteers. No relationship was established between microalbuminuria and cognitive functions, although diabetic neuropathy was found to be related to decreased cognitive function.

Retrospective Evaluation of Bone Metastases in Patients With Thyroid Malignancy: A Single-Center Experience.

Background Thyroid cancer is one of the five most common cancers causing bone metastasis. If there is an increase in serum thyroglobulin-antithyroglobulin levels in differentiated thyroid cancer or calcitonin levels in medullary thyroid cancer, patients should be evaluated for recurrence and distant metastasis. The skeleton is the second most common site of distant metastasis in thyroid cancer after the lung. Bone metastases cause pain, fractures, and spinal cord compression, severely reducing the quality of life. They are associated with poor prognosis. Bone metastases severely reduce the quality of life. This study aimed to retrospectively evaluate the diagnosis and follow-up of patients with thyroid cancer with bone metastases diagnosed at our center. Methodology A total of 1,390 patients diagnosed with thyroid malignancy at our center between 2010 and 2023 were reviewed retrospectively. The study included 27 patients with differentiated and medullary thyroid cancer who had bone metastases. Results Of 27 patients, 19 (70.4%) had differentiated and eight (29.6%) had medullary thyroid cancer. Papillary thyroid cancer constituted 22.2% (n = 6) and follicular thyroid cancer constituted 14.8% (n = 4) of the cases. Papillary carcinoma follicular variant, oncocytic, and poorly differentiated thyroid cancer were diagnosed with similar frequency, each accounting for 11.1% (n = 3). It was found that vertebrae were most commonly involved, followed by the pelvis, sternum, costae, femur and patella, shoulder and humerus, cranium, and scapula. The five-year survival rate was 72%, and the 10-year survival rate was 53%. Conclusions The number of patients with papillary cancer was the highest, but the rate of bone metastases was the lowest in this group. The highest rate of bone metastases was found in patients with poorly differentiated, oncocytic, medullary, follicular, and papillary cancer, respectively. The results obtained in this study reveal the necessity and importance of bone metastasis evaluation in patients with thyroid cancer.

Comparative genotoxic and cytotoxic effects of the oral antidiabetic drugs sitagliptin, rosiglitazone, and pioglitazone in patients with type-2 diabetes: a cross-sectional, observational pilot study.

This cross-sectional, observational pilot study was designed to investigate the frequency of different endpoints of genotoxicity (sister-chromatid exchange, total chromosome aberrations, and micronucleus formation) and cytotoxicity (mitotic index, replication index, and nuclear division index) in the peripheral lymphocytes of patients with type-2 diabetes treated with different oral anti-diabetic agents for 6 months. A total of 104 patients who met the American Diabetes Association criteria for type-2 diabetes were enrolled in the study. Of the 104 patients, 33 were being treated with sitagliptin (100mg/day), 25 with pioglitazone (30mg/day), 22 with rosiglitazone (4mg/day), and 24 with medical nutrition therapy (control group). The results for all the genotoxicity endpoints were significantly different across the four study groups. Post hoc analysis revealed that the genotoxicity observed in the sitagliptin group was significantly higher than that observed in the medical nutrition therapy group, but lower than that occurring in subjects who received thiazolidinediones. All of the three cytotoxicity endpoints were significantly lower in patients treated by oral anti-diabetic agents compared with those who received medical nutrition therapy. However, the three indexes did not differ significantly in the sitagliptin, rosiglitazone, and pioglitazone groups. Taken together, these pilot data indicate that sitagliptin and thiazolidinediones may exert genotoxic and cytotoxic effects in patients with type-2 diabetes. Further investigations are necessary to clarify the possible long-term differences between oral anti-diabetic drugs in terms of genotoxicity and cytotoxicity, and how these can modulate the risk of developing diabetic complications in general and cancer in particular.

Central venous sampling and magnetic resonance imaging in the diagnosis of ACTH-dependent Cushing's syndrome.

OBJECTIVES: Central venous sampling (CVS) with corticotropin-releasing hormone (CRH) stimulation is a crucial technique in evaluating adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome (CS). We evaluated central venous sampling (CVS) and magnetic resonance imaging (MRI) findings in predicting the localization and lateralization of pituitary microadenomas. METHODS: We analyzed 29 patients with CS who underwent CVS with CRH stimulation and examined with MRI retrospectively. Catheterization to central sinuses was successfully performed in 26 patients. Three patients with variant anatomy or inability to cannulate were diagnosed with CD after examination of pathology. RESULTS: After CVS, among 26 patients, 23 patients were determined to have CD (88.4%) and 2 (7.7%) patients were diagnosed with ectopic ACTH syndrome. One patient was diagnosed with CD postoperatively. While the sensitivity of the CVS was 95.6%, sensitivity of the preoperative pituitary MRI was lower (69.5%). Also, the negative predictive value ratio was higher in CVS than in MRI (66% versus 22%). Diagnostic accuracy in the lateralization of the tumor was high as in CVS as in MRI (76.4% versus 73.9%). CONCLUSION: Central venous sampling with higher sensitivity in the localization of pituitary microadenoma, also has approximately similar diagnostic accuracy in lateralizing the tumor with MRI.

Co-existence of Papillary and Medullary Thyroid Carcinoma: Reports of Three Cases.

Medullary thyroid carcinoma (MTC) and papillary thyroid carcinoma (PTC) are two different types of thyroid carcinoma. They have different features in terms of cellular origin, histopathology, clinical features, prevalence, and prognosis. PTC originates from follicular cells, while MTC from parafollicular cells. MTC and PTC co-existence is a rare phenomenon and occurs in less than 1% of all thyroid tumors. We report three cases with coexistent MTC and PTC in the same thyroid. The papillary component was dominant in two cases and the medullary in one case. While the first case was given radioactive iodine therapy, the third was treated with vandetanib. The second case was followed up postoperatively and did not receive treatment other than levothyroxine replacement. The co-existence of these tumors requires a different clinical approach in treatment and follow-up, depending on which type is dominant. Key Words: Mixed thyroid carcinoma, Papillary thyroid carcinoma, Medullary thyroid carcinoma.

How the COVID-19 outbreak affected patients with diabetes mellitus?

Background: Global COVID-19 outbreak has been such a stressful experience for most of the people. Using a web-based cross-sectional study, we aimed to evaluate the acute stress response, depression, and anxiety in patients with diabetes mellitus (DM) during the COVID-19 pandemic, and to examine the effect of these psychiatric problems on diet habits and glycemic controls of patients. Methods: This web-based survey of COVID-19 was sent to the patients through the Whatsapp platform. All participants reported their demographic data, diabetes-related information, changes in self-monitoring blood glucose measurements, physical parameters, and eating habits after COVID-19, then completed Hospital Anxiety and Depression Scale (HADS) and the Impact of Event Scale, Revised (IES-R) questionnaires which assessed acute stress sypmtoms, anxiety, and depression. Results: Three hundred and four patients with DM [(141 type 1 DM (T1D) and 163 type 2 (T2D)] were included in the study. In our study, female gender, higher BMI and weight, decreased in financial income after outbreak, presence of diabetic complications and comorbid diseases (i.e., retinopathy, neuropathy, diabetic foot, hypertension, dyslipidemia), worsened glycemic levels, increased carbohydrate consumption, and snacking were associated with higher anxiety and depression scores. Depression was higher in patients with T2D and duration of illness was correlated with acute stress level. Conclusions: It is important to be aware of the possibility of acute stress, depression, and anxiety after pandemic in patients with DM whose glycemic control is impaired. Psychological problems should not be ignored beyond physical inactivity and worsening eating habits.

Comparison of the effects of medical and surgical treatments in giant prolactinoma: a single-center experience.

PURPOSE: Giant prolactinomas, which have extremely large sizes and high prolactin (PRL) values, are rarely seen. Although medical therapy is effective, surgical treatment is more frequently applied due to slightly lower response rates and compression symptoms. This study aimed to compare the medical and surgical treatment results in giant prolactinomas. METHODS: Thirty-nine patients who were followed up in our center for giant prolactinoma were included in the study, and the response rates of the patients were evaluated after the medical and surgical treatments. The treatment responses were compared in terms of tumor volume, PRL level, visual field, and pituitary function. RESULTS: The outcomes of the 66 treatment periods (medical n = 42; surgical n = 24) in 39 patients (mean age, 47.2 years; men, 89.7%) were evaluated. The most common presentations were hypogonadism and visual defects. The mean longest tumor diameter at diagnosis was 52.2 ± 11.8 mm, and the median PRL levels were 5000 ng/mL. PRL level normalization was achieved in 69% with medical therapy, and a curative response was obtained in only two patients with surgery. Tumor volume reduction was 67% (no cure) in the medical and 75% (13% cure) in the surgical groups (p = 0.39). Improvement of visual field was 70.8% in the medical and 84.2% in the surgical group (p = 0.12). CONCLUSION: In our study, it was observed that medical therapy was effective and safe in patients with giant prolactinomas. The use of surgical treatment should be limited to prolactinomas with compression or post-resistance to medical treatment in serious cases.

Insulinoma Case Admitted with Reactive Hypoglycemia Symptoms.

AIM: To present an insulinoma case with post-prandial hypoglycemic symptoms associated with glucose inducible endogenous hyperinsulinemia. CASE: A 52-year-old female patient was evaluated for hypoglycemic symptoms especially those occuring within 3 hours after consuming sugary foods. These symptoms were persistent for a year and a half. She was diagnosed with reactive (post-prandial) syndrome and followed a recommended diet and was given acarbose but there was no improvement. The results suggested post-prandial endogenous hyperinsulinemia related hypoglycemia. Multiphasic computerized tomography revealed an 11x15x12 mm size mass lesion, anteriorly in the head and uncinate process of the pancreas and then the patients were treated surgically with pancreatic enucleation and cured. CONCLUSION: Distinguishing post-prandial syndrome by careful history and clinical evaluation in patients with postprandial symptoms is of great importance in terms of cost-effectivity. However, it should not be forgotten that although organic pathologies are mostly presented with fasting hypoglycemia, they may also cause post-prandial symptoms. Severity and progression of the symptoms that point to neuroglycopenia is important, and in this condition the most convenient clinical approach to the patient should be performed with careful and appropriate assessment steps.

Control of Refractory Hypercalcemia with Denosumab in a Case of Metastatic Parathyroid Carcinoma.

Parathyroid carcinoma is a rare cause of hyperparathyroidism and leads to severe hypercalcemia. The etiology is not fully known. Parathyroid cancer should be considered in the differential diagnosis, if serum calcium and parathyroid hormone levels increase, and parathyroid gland is palpable. Severe hypercalcemia is the most common cause of death in patients diagnosed with parathyroid carcinoma. Fluid replacement, diuretic therapy, bisphosphonates, and calcimimetic agents are the main treatment steps in the control of life-threatening hypercalcemia. Surgery is the primary treatment option, while denosumab is a treatment option for refractory hypercalcemia caused by parathyroid carcinoma, or for patients who are not eligible for surgery. There are few case reports in literature about denosumab treatment for parathyroid carcinoma. Herein, we report a case of a patient who presented with the complaint of leg pain and was diagnosed with parathyroid carcinoma. The elevated calcium level of the patient was controlled with denosumab. Key Words: Parathyroid carcinoma, Denosumab, Hypercalcemia, Hyperparathyroidism.

Lipid profile in type 2 diabetic patients with new dapagliflozin treatment; actual clinical experience data of six months retrospective lipid profile from single center.

INTRODUCTION: Dapagliflozin is a sodium-glucose cotransporter 2 inhibitor that improves glycemic control in patients with type II diabetes mellitus which increasing urinary glucose excretion. With numerous controlled experimental studies of dapagliflozin, evaluation of real-life data after entry into clinical practice is an important condition. In our study, the effects of dapagliflozin (10 mg) on lipid profile were investigated retrospectively. METHODS: A total of thirty-one type 2 diabetic patients with HbA1c level between 6,5% and 13%, aged 45-80 years and whose body mass index higher than 20 kg/m2 were enrolled to the study. Data before dapagliflozin treatment and three and six months results were recorded. RESULTS: Dapagliflozin reduced HbA1c levels by 0,9% at 3 months and 0,79% at 6 months. Total cholesterol level decreased 17,6 mg/dl, LDL cholesterol level decreased 13,4 mg/dl and triglyceride level by 25.9 mg/dl at the 6th months and it is observed that there is no serious side effect on the usage for 6 months. CONCLUSION: There are conflicting results about the effect of SGLT2 inhibitors on the lipid profile in the literature. According to our data, dapagliflozin has positive effects on lipid profile as weight and glycemic control and it is well tolerated. Therefore, dapagliflozin therapy is beneficial because of the positive change in lipid profile and weight loss in diabetic patients with overweight and hyperlipidemia.

Anthropometric outcomes in type 2 diabetic patients with new dapagliflozin treatment; actual clinical experience data of six months retrospective glycemic control from single center.

INTRODUCTION: Dapagliflozin is an antidiabetic drug that has been used as a member of the new antidiabetic drug group that acts by inhibiting SGLT-2 and increasing urinary glucose excretion. With numerous controlled experimental studies of dapagliflozin, evaluation of real-life data after entry into clinical practice is an important condition. In our study, the effects of dapagliflozin on glycemic control and anthropometric measurements were investigated retrospectively. METHODS: A-total of thirty-one type 2 diabetics were enrolled in the study. Data of before dapagliflozin and three and six months of treatment were recorded. RESULTS: Dapagliflozin reduced HbA1c levels by 0,9% at 3 months and 0,79% at 6 months. Fasting plasma glucose decreased 41,1 mg/dl in the 3rd and 42 mg/dl in the 6th, postprandiyal glucose decreased 86,3 mg/dl in the 3rd and 74,2 mg/dl in the 6th. In the 3rd and 6th, body weights decreased by 3,3 kg and 4,2 kg, BMI decreased by 1,3 kg/m2 and 1,6 kg/m2 respectively. Similarly, it was observed that the waist circumference decreased by 1,3 cm at the end of 6th. CONCLUSION: Our data show that SGLT-2 inhibitors provide glycemic control with reduce HbA1c levels by 0.8-0.9%, and reduce fasting and postprandial plasma glucose levels without increasing the risk of hypoglycemia and causing weight lose around 5% at the six mounths. SGLT-2 inhibitors were found to be more effective in reduce postprandiyal plasma glucose in patients who did not use insulin and fasting plasma glucose in patients with diabetes mellitus less than 10 years.

Evaluation of upper gastrointestinal system in acromegaly.

PURPOSE: Acromegaly causes multiple comorbidities, including gastrointestinal disorders. The present study evaluated the frequency of hiatal hernia and other upper gastrointestinal pathologies in patients with acromegaly, given that visceromegaly and reduced nitric oxide levels in acromegaly may impact diaphragm and lower esophageal sphincter function and thus possibly the development of hiatal hernia. METHODS: Thirty-nine acromegaly patients followed our center for the previous 6months were recruited. Upper gastrointestinal endoscopy was performed once in all patients to evaluate hiatal hernia, esophagitis, gastroduodenitis and ulcer. RESULTS: Twenty-three patients were male and 16 female. Upper gastrointestinal endoscopy found hiatal hernia, esophagitis and gastroduodenitis or gastric ulcer in 3 (7.6%), 2 (1.7%) and 31 (79.4%) patients, respectively. Pathologic examination of gastric antrum biopsy found intestinal metaplasia in 12 (30.7%) patients, and Helicobacter pylori was positive in 13 (33.3%). There were no significant correlations between age, gender, disease duration or preoperative adenoma size on the one hand and hiatal hernia or other endoscopic findings on the other. Similarly, neither surgical success nor recurrence was associated with endoscopic findings. CONCLUSIONS: The study showed that prevalence of gastritis, duodenitis, peptic ulcer and intestinal metaplasia is higher and prevalence of hiatal hernia lower in acromegaly patients than in the healthy population. Various unknown disease-related pathophysiological conditions may play a role; there is a need for further studies.

The relationship between arteriovenous fistula blood flow rate and pulmonary artery pressure in hemodialysis patients.

PURPOSE: Although there is an increased prevalence of pulmonary hypertension in hemodialysis patients, the relationship between arteriovenous (AV) fistula blood flow and pulmonary hemodynamics is not known. The aim of this study was to evaluate the relationship between blood flow rate of AV fistula and pulmonary artery pressure (PAP) in hemodialysis patients. METHODS: Thirty-two hemodialysis patients were included in this study. Within 1 h of completion of dialysis, blood flow rate of AV fistula and pulmonary hemodynamics were evaluated using Doppler sonography. Pulmonary hypertension was defined as mean PAP > or = 25 mmHg at rest. RESULTS: Mean PAP, median blood flow rate of AV fistula, and mean cardiac index were 22.5 +/- 10.0 mmHg (range 8-39), 978.0 ml/min (interquartile range 762.0-1,584.5) and 3,043.0 +/- 694.3 ml/ min per m2 (range 1,251-4,140), respectively. Mean PAP has a relationship to cardiac index (r = 0.453, P = 0.014). However, there was no correlation between mean PAP and blood flow rate of AV fistula, hemoglobin, calcium-phosphorus (CaxP) product, and parathormone. Pulmonary hypertension was present in 43.7% of patients. Patients with pulmonary hypertension had significantly higher cardiac index (P = 0.036). CONCLUSIONS: We found there was no direct relationship between blood flow rate of AV fistula and PAP. Other factors may play a role in the development of pulmonary hypertension.
