Objectives: To describe biochemical and clinical features, and therapeutic outcomes of acromegaly patients in Turkey. Methods: Retrospective multicenter epidemiological study of 547 patients followed in 10 centers of the Turkish Acromegaly registry. Results: A total of 547 acromegaly patients (55% female) with a median age of 41 was included in this study. Majority of patients had a macroadenoma (78%). Transsphenoidal surgery was performed as primary treatment in 92% of the patients (n = 503). Surgical remission rate was 39% (197/503) in all operated patients. Overall disease control was achieved in 70% of patients. Remission group were significantly older than non-remission group (p = .002). Patients with microadenomas had significantly higher remission rates than patients with macroadenomas (p < .001). Patients with microadenomas were significantly older at the time of diagnosis when compared to patients with macroadenomas (p < .001). Preoperative growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels were significantly lower in the remission group (p < .001). Initial IGF-1 and GH levels were significantly higher in macroadenomas compared to microadenomas (p < .001). Medical treatment was administered as a second-line treatment (97%) in almost all patients without remission. Radiotherapy was preferred in 21% of the patients mostly as a third line treatment. Conclusions: This is one of the largest real life studies evaluating the epidemiological characteristics and treatment outcomes of patients with acromegaly who were followed in different centers in Turkey. Transsphenoidal surgery in the treatment of acromegaly still remains the most valid method. Medical treatment options may improve long-term disease outcomes in patients who cannot be controlled with surgical treatment (up to 70%).

(2014) Sizmaz, Selcuk; Altan-Yaycioglu, Rana; Bakiner, Okan Sefa; Bozkirli, Emre; Coban-Karatas, Muge; Ulas, Burak; https://orcid.org/0000-0002-9139-8848; 24215623; AAG-3306-2019; AAK-5525-2021; E-9887-2014; AEP-4897-2022
Purpose: To evaluate the tear-film meniscus with optical coherence tomography (OCT) in patients with Graves' disease (GD). Materials and methods: Patients with GD without clinical features of thyroid-associated ophthalmopathy (TAO) (Group 1, n = 35), patients with signs of TAO (Group 2, n = 31) and healthy participants (Group 3, n = 31) were enrolled. Palpebral fissure width, Schirmer test, tear break-up time (TBUT) test and tear-film meniscus height and area obtained with Fourier-domain-OCT were analyzed. Results: TBUT test scores were 8 s (2-25) in Group 1, 8 s (2-15) in Group 2 (p = 0.380); and10 s (5-17) in Group 3 (p = 0.000 Group 1 versus 3, and 0.000 for Group 2 versus 3). Tear-film meniscus height did not significantly differ between Groups 1 and 2 (257.5 mm (86-962) and 258 mm (99-1340), respectively, p = 0.980). In Group 3, tear-film meniscus height was 316 mm (122-720) (p = 0.005 Group 1 versus 3 and 0.004 for Group 2 versus 3). Tear-film meniscus area did not significantly differ between Groups 1 and 2 (0.025mm(2) (0.004-0.250) and 0.024mm(2) (0.003-0.316), respectively, p = 0.850). In Group 3, tear-film meniscus area was 0.048mm(2) (0.006-0.75) (p = 0.000 Group 1 versus 3 and 0.000 for Group 2 versus 3). Conclusion: Tear function is significantly disturbed in GD. OCT is an effective way to assess the tearing function also in patients with GD.
Association between Serum Osteopontin Levels and Cardiovascular Risk in Hypothyrodism
(2016) Duman, Gulhan; Ertorer, Eda Melek; Mete, Turkan; Bozkirli, Emre; Bakiner, Okan Sefa; Tutuncu, Neslihan Bascil
Purpose: Cardiovascular effects of hypothyroidism are well known. Osteopontin (OPN) is a new inflammatory marker which was first isolated from the bone. Flow-mediated dilatation (FMD), a noninvasive technique to measure this endothelium-dependent function, has been used in several clinical studies to show cardiovascular risks. The aim of our study was to assess FMD value in hypothyroidism patients and to investigate whether plasma OPN level is a parameter which can predict cardiovascular risks in this group of patients. Material and Method: This study included 39 patients who had high levels of thyroid-stimulating hormone (TSH) and 11 healthy euthyroid controls. Plasma TSH, free thyroxine, fibrinogen, high-sensitive C-reactive protein (hsCRP), fasting plasma glucose, total cholesterol (T-chol), low density lipoprotein (LDL), triglyceride and OPN levels were measured at the time hypothyroidism was first detected and after euthyroid state was achieved with levothyroxine treatment. In parallel with these assessments, brachial FMD measurements were also performed. Results: In hypothyroid patients cardiovascular risk factors such as T-chol, LDL and triglyceride levels were higher than in control group but fibrinogen and hsCRP levels were not different between the groups. OPN levels were similar in patient and control groups, but basal FMD levels were lower in patients with hypothyroidism. After euthyroidism was achieved, OPN levels significantly decreased and FMD levels significantly increased, but a correlation was not detected between these two parameters. Discussion: Our study did not show a significant correlation between OPN and cardiovascular risk parameters. Further studies are needed to use OPN as a cardiovascular risk marker in hypothyroid patients.

(2016) Bagir, Gulay Simsek; Bakiner, Okan S.; Bozkirli, Emre; Cavlak, Gulhan; Serinoz, Hulya; Ertorer, M. Eda; 26335185
Objective: The aim of this study was to determine the cardiometabolic risk factors in different polycystic ovary syndrome (PCOS) phenotypes. Subjects and Methods: This cross-sectional study was performed between 2010 and 2011. Eighty-nine patients with PCOS and 25 age- and weight-matched healthy controls were included in the study. Patients were grouped using the Rotterdam 2003 criteria as: group 1, oligomenorrhea and/or anovulation (ANOV) and hyperandrogenemia (HA) and/or hyperandrogenism (n = 23); group 2, ANOV and polycystic ovaries (PCO; n = 22); group 3, HA and PCO (n = 22); group 4, ANOV, HA and PCO (n = 22); group 5, controls (n = 25). Laboratory blood tests for diagnosis and cardiometabolic risk assessments were performed. Insulin resistance (IR) was calculated in all patients with the homeostasis model assessment of IR (HOMA-IR) formula. An euglycemic hyperinsulinemic clamp test was performed on 5 randomly selected cases in each subgroup, making 25 cases in total, and indicated as the 'M' value (mg/kg/min), which is the total body glucose disposal rate. Results: The mean BMl values of the groups were: group 1, 26.1 +/- 5.3; group 2, 27.9 +/- 5.2; group 3, 24.3 +/- 4.2; group 4, 27.9 +/- 7.5; group 5, 24.7 +/- 5.2 (p > 0.05). There were no differences in the lipid profile, plasma glucose, HOMA-IR, insulin and M values between the groups (p > 0.05). Phenotypes with oligomenorrhea/anovulation (groups 1, 2 and 4) were more obese than group 3 (p = 0.039). Conclusions: The cardiometabolic risk profile was similar among the PCOS subgroups. This finding could be attributed to the mean BMl values, which, being below 30, were not within the obesity range. Obesity appeared to be an important determinant of high cardiovascular risk in PCOS.

Effects of Infliximab Treatment in Terms of Cardiovascular Risk and Insulin Resistance in Ankylosing Spondylitis Patients
(2014) Bozkirli, Emine Duygu Ersozlu; Bozkirli, Emre; Yucel, Ahmet Eftal; https://orcid.org/0000-0002-4860-9072; 24252046; E-9887-2014
Objective. To assess the effects of infliximab treatment on insulin sensitivity and cardiovascular risk factors in patients with ankylosing spondylitis (AS). Methods. In this prospective study, 30 consecutive AS patients (23 men and 7 women) fulfilling the modified 1984 New York criteria for AS were investigated. All patients were treated with intravenous infliximab. A complete biochemical profile and assesments were obtained before and after 12 weeks of infliximab therapy. The Homoeostasis Model Assessment of Insulin Resistance Index (HOMA-IR) was used to measure insulin resistance (IR). Framingham equation was used to assess cardiovascular risk factors. Results. After 12 weeks of infliximab treatment, there was no statistically significant difference in fasting insulin, HOMA-IR, lipid parameters, body-mass index, waist circumference and waist hip ratio, whereas fasting glucose levels (p = 0.001), triglycerides/high-density lipoprotein (HDL) ratio (p = 0.043) and total cholesterol/HDL (p = 0.041) ratio increased significantly from baseline. A significant decrease was observed for both systolic blood pressures (p < 0.001) and diastolic blood pressures (p = 0.003) in the 12th-week visit. A significant decrease was also found in terms of Framingham risk scores (p = 0.028) after treatment. Conclusions. Study results suggest that infliximab treatment may reduce cardiovascular risk and blood pressures without changing IR.
Impact of Obesity on the Metabolic Control of Type 2 Diabetes: Results of the Turkish Nationwide Survey of Glycemic and Other Metabolic Parameters of Patients with Diabetes Mellitus (TEMD Obesity Study)
(2019) Bascil Tutuncu, Neslihan; Bozkus, Yusuf; Bozkirli, Emre; 30893706
Background: Obesity is the main obstacle for metabolic control in patients with type 2 diabetes. Turkey has the highest prevalence of obesity and type 2 diabetes in Europe. The effect of obesity on the metabolic control, and the macro-and microvascular complications of patients are not apparent. Objectives: This nationwide survey aimed to investigate the prevalence of overweight and obesity among patients with type 2 diabetes and to search for the impact of obesity on the metabolic control of these patients. We also investigated the independent associates of obesity in patients with type 2 diabetes. Methods: We consecutively enrolled patients who were under follow-up for at least 1 year in 69 tertiary healthcare units in 37 cities. The demographic, anthropometric, and clinical data including medications were recorded. Patients were excluded if they were pregnant, younger than 18 years, had decompensated liver disease, psychiatric disorders interfering with cognition or compliance, had bariatric surgery, or were undergoing renal replacement therapy. Results: Only 10% of patients with type 2 diabetes (n = 4,648) had normal body mass indexes (BMI), while the others were affected by overweight (31%) or obesity (59%). Women had a significantly higher prevalence of obesity (53.4 vs. 40%) and severe obesity (16.6 vs. 3.3%). Significant associations were present between high BMI levels and lower education levels, intake of insulin, antihypertensives and statins, poor metabolic control, or the presence of microvascular complications. Age, gender, level of education, smoking, and physical inactivity were the independent associates of obesity in patients with type 2 diabetes. Conclusion: The TEMD Obesity Study shows that obesity is a major determinant of the poor metabolic control in patients with type 2 diabetes. These results underline the importance of prevention and management of obesity to improve health care in patients with type 2 diabetes. Also, the results point out the independent sociodemographic and clinical associates of obesity, which should be the prior targets to overcome, in the national fight with obesity.

Insulin Resistance in Non-Obese Polycystic Ovary Syndrome Subjects and Relation with Family History of Diabetes Mellitus
(2015) Bozkirli, Emre; Bakiner, Okan; Ertorer, Eda; Anaforoglu, Inan; Tutuncu, Neslihan Basil; Demirag, Nilgun Guvener
Purpose: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women in reproductive age. Conflicting results are reported in the studies examining insulin resistance in lean PCOS subjects. We aimed to observe the controversial presence of insulin resistance in lean PCOS subjects with the gold standard method and assess the impacts of family history of type 2 diabetes mellitus (T2DM) on insulin resistance in these patients. Material and Method: Nineteen patients with PCOS and nine age-BMI matched control subjects were recruited into the study. Patients with PCOS were divided into two groups according to their FH of T2DM among their first degree relatives (FHneg vs FHpos). Insulin resistance was evaluated with homeostasis model assessment of insulin resistance (HOMA-IR) and hyperinsulinemic euglycemic clamp technique for all participants. Results: Mean M values were significantly higher in the control group when compared with PCOS patients (p=0.003). There was no statistically significant difference for HOMA-IR and M values when FHneg and FHpos patients were compared. Although HOMA-IR values were similar between all groups, M values were lower in FHneg and FHpos groups compared to the controls (p=0.02 and 0.004 respectively). Discussion: Lean PCOS patients have evident insulin resistance when compared to healthy subjects, and FH of T2DM seems to not affect insulin resistance. Even non-obese PCOS patients should be encouraged for healthy eating style and exercise to prevent the potential risks associated with insulin resistance. Furthermore these patients can see benefits from medical therapies which improve insulin sensitivity.

(2014) Ertorer, Melek Eda; Serinsoz, Hulya Karaoglu; Bascil, Sibel; Bakiner, Okan Sefa; Bozkirli, Emre; Tutuncu, Neslihan Bascil; https://orcid.org/0000-0001-7357-8709; https://orcid.org/0000-0002-1644-6790; https://orcid.org/0000-0002-1816-3903; ABI-3705-2020; AAA-8309-2021; AAK-5525-2021; E-9887-2014; ABG-5027-2020
Low Prevalence of Periodontitis in Acromegaly: Growth Hormone May Exert a Protective Effect
(2015) Serinoz, Hulya; Ertorer, Melek Eda; Bascil, Sibel; Bakiner, Okan; Bozkirli, Emre; Tutuncu, Neslihan B.
Purpose: To evaluate bone mineral density (BMD) measurements and the presence of periodontitis in patients with acromegaly, as well as to inquire the impact of interfering factors. Material and Method: Forty-seven acromegalic patients with any accompanying condition known to affect calcium-bone metabolism and 60 age-matched healthy controls were included. Age, gender, duration and activity of acromegaly, past-present therapy options, pituitary hormone profiles, replacement therapies, and the results of periodontal analysis were recorded. Results: Eighteen patients were male (38.3%), 29 were female (61.7%). The mean age of the patients was 46.6 +/- 11.5 years, twenty-five (53.1%) had active, 22 (46.8%) had inactive acromegaly. The latter were older and had longer disease duration (p=0.04, p=0.003, respectively). Serum calcium and phosphorus levels, 24-hour urinary calcium excretion and BMD at the lumbar spine and femur neck insignificantly associated with disease activity (p>0.05). Osteoporosis was detected in 6 patients (12.76%). Periodontitis and advanced periodontitis were more common in control group (66.7% vs. 44.7%), (43.3% vs. 12.8%) (p=0.022, p=0.0001, respectively). There was no difference in chronic periodontitis and severity between active and inactive groups (48% vs. 40.9%; p=0.279). No difference was noted in other study parameters, as well. Repeated measures analysis of variance demonstrated statistically insignificant distribution between GH change in time and periodontitis subgroups. Discussion: We demonstrated that acromegaly exerted no clear negative impact on vertebral BMD in the absence of overt hypogonadism. Regardless of disease activity, acromegaly cases exhibited lower rates of periodontitis with less severity which remained unchanged in the presence of accompanying metabolic disorders known to have negative impact on periodontal tissue. Chronic exposure to excess GH may have a protective role against periodontitis.
Mean platelet volume in Graves' disease: A sign of hypermetabolism rather than autoimmunity?
(2017) Bagir, Gulay Simsek; Haydardedeoglu, Filiz Eksi; Bakiner, Okan Sefa; Bozkirli, Emre; Ertorer, Melek Eda; 0000-0002-1644-6790; 0000-0002-0179-9673; 0000-0001-7357-8709; 29067056; AAK-5525-2021; E-9887-2014; AAK-5003-2021; ABI-3705-2020
Objective: To evaluate the impact of mean platelet volume (MPV) on predicting disease course among patients with Graves' disease (GD). Methods: This retrospective study was performed between 2013-2016 at the Outpatient Endocrinology Clinic of Baskent University Faculty of Medicine, Adana hospital on 65 patients with GD. Among participants, 30 cases experienced thyrotoxicosis again during the first six months after discontinuing anti-thyroid drug (ATD) sessions that had been carried out for at least 12 months prior to stopping (Relapse group). We also observed 35 patients who exhibited normal thyroid functions within six months following ATD withdrawal (Remission group). MPV levels and thyroid function tests were recorded and total duration of ATD therapy was calculated for all participants. Results: The mean MPV level that was measured at the time of drug withdrawal did not differ between groups, being 8.0 +/- 1.2 fL in the Relapse group vs. 8.0 +/- 1.0 fL in the Remission group (p=0.81). However, we found that the relapse MPV was higher than the withdrawal MPV in the Relapse group (9.2 +/- 1.3 fL) than it was in the Remission group (8.0 +/- 1.2 fL, p=0.00). Conclusions: Higher relapse MPV in Relapse group but similar MPV levels in both groups at ATD withdrawal may be attributed to hypermetabolism or hyperthyroidism rather than autoimmunity of GD.

(2014) Bakiner, Okan; Bozkirli, Emre; Ertugrul, Derun; Sezgin, Nurzen; Ertorer, Eda
Objective: To determine plasma fetuin-A levels in hypothyroid patients before and after treatment with L-thyroxine (T-4) and to determine the relation between plasma fetuin-A levels with cardiovascular risk factors. Design: A prospective, controlled, single-blind study. Methods: Forty-four treatment-naive female patients diagnosed with hypothyroidism and 39 age-and sex-matched control subjects were enrolled. Anthropometric measurements, blood pressure, plasma TSH, fetuin-A, free T-4, LDL-cholesterol, triglyceride, C-reactive protein, fibrinogen levels, and brachial artery flow-mediated dilatation were measured. All measurements were repeated after 3 months in the control group and 3 months after the attainment of euthyroidism with (L)-T4 replacement in the hypothyroid group. Baseline data were compared between the two groups. Posttreatment plasma fetuin-A levels of hypothyroid patients were compared with baseline levels of both groups. The relationship between plasma fetuin-A, TSH levels, and other cardiovascular risk factors was evaluated. Results: Plasma fetuin-A levels were similar to 20% lower in hypothyroid female patients compared with the controls (P=0.0001). Fetuin-A levels increased by similar to 20% in hypothyroid patients after achievement of euthyroidism (P=0.0001) and were no longer different compared with controls (P=0.38). There was a negative correlation between plasma TSH and fetuin-A levels (r=-0.79; P=0.001). There was no significant correlation between plasma fetuin-A levels and cardiovascular risk factors within or between groups. The fetuin-A levels were normalized with thyroid hormone treatment. Conclusion: Plasma fetuin-A levels are reduced in female patients with hypothyroidism, which are restored to normal during restoration of euthyroidism. There was no relation with cardiovascular risk factors.

(2016) Haydardedeoglu, Filiz Eksi; Torun, Ayse Nur Izol; Andic, Cagatay; Bakiner, Okan; Bozkirli, Emre; kayaselcuk, Fazilet; Ertorer, Melek Eda
Insulinoma is the most common type of islet cell tumor of the pancreas and its incidence is estimated at four per one million persons per year. Although fasting hypoglycemia is the typical presentation, cases with postprandial hypoglycemia have rarely been reported. A 48-year-old woman was admitted to our department for evaluation of hypoglycemia. Laboratory data suggested a state of postprandial endogenous hyperinsulinemic hypoglycemia. Abdominal computed tomography revealed a mass lesion measuring 20 mm at the distal pancreas. A decision was made to perform an arterial calcium-stimulated venous sampling for excluding nesidioblastosis coexisting with a pancreatic incidental mass. After that the patient was referred to surgery. Pathological examination revealed a low-grade well-differentiated neuroendocrine tumor with regional lymph node metastasis. Herein, we report a case of malignant insulinoma presenting with postprandial hypoglycemia and discuss the differential diagnosis and possible mechanisms of postprandial hypoglycemia in insulinoma cases.

Betatrophin is defined as a new marker in glucose homeostasis and lipid metabolism. We aimed to investigate the role of serum betatrophin in full-blown polycystic ovary syndrome (PCOS) patients and 47-aged healthy women, 51 full-blown PCOS patients were included in this cross-sectional study. Betatrophin concentrations were significantly lower in PCOS group and displayed a positive correlation only with serum tryglyceride in control group (p < .05). A cutoff level (464.5 ng/L) was determined for betatrophin according to Receiver Operating Characteristic curve. Using this value, 64.7% of PCOS patients were classified as below the cutoff and in this group betatrophin was found to correlate negatively with fasting glucose, fasting insulin, and homeostasis model assessment of insulin resistance (p = .038, p = .020, and p = .014, respectively), and positively with total testosterone (p = .041). In the rest of PCOS cases (35.3%) who had betatrophin higher than cutoff, positive correlation was found with low-density lipoprotein cholesterol (p = .009). In conclusion, betatrophin levels are reduced in full-blown PCOS patients who had worse metabolic phenotype.
Serum Immunoglobulin G4 Levels are Elevated in Patients with Graves' Ophthalmopathy
(2015) Bozkirli, Emre; Bakiner, Okan Sefa; Bozkirli, Emine Duygu Ersozlu; Haydardedeoglu, Filiz Eksi; Sizmaz, Selcuk; Torun, Aysenur Izol; Ertorer, Melek Eda; 0000-0002-1644-6790; 0000-0002-0179-9673; 0000-0001-7357-8709; 25400133; E-9887-2014; AAK-5525-2021; AAK-5003-2021; ABI-3705-2020
Objective Recent studies have shown close association between serum Immunoglobulin G4 (IgG4) levels and forms of autoimmune thyroiditis. However, there are limited data about the relationship between IgG4 and Graves' ophthalmopathy (GO). In the present study, we aimed to determine the possible association between IgG4 and GO. Design Cross-sectional study. Patients Sixty-five patients with Graves' disease (GD) and 25 healthy controls were recruited into the study. Thirty-two of these patients had GO. Measurements Serum IgG4 levels, thyroid functions and thyroid volumes were measured in all participants. Ophthalmological examination including Hertel's exophthalmometer readings (HER), Schirmer's test (ST), 'NO SPECS' classification and clinical activity score evaluation (CAS) were performed to all patients with GD. Results IgG4 levels were significantly elevated in patients with Graves' disease compared to controls (P = 0.0001). Also, IgG4 levels were significantly higher in patients with and without GO when compared to control subjects (P = 0.0001 and P = 0.002, respectively). Furthermore, IgG4 levels were significantly higher in the GO group compared with GD patients without GO (P = 0.024). IgG4 levels were observed to increase in parallel to CAS. Compared with other GD patients, 15 GD patients with serum IgG4 levels >= 135 mg/dl had higher CAS scores (P = 0.012). None of the factors including, TSH, T3, T4 levels, thyroid volume, HER and ST measurements, affect IgG4 levels as an independent factor. Conclusion IgG4 levels are evidently increased in patients with GD, and there is a possible relationship between IgG4 and GO. Our results suggest that IgG4 may be helpful in screening GD patients with high risk for GO and may well become a good indicator for the selection of right medication in the future.
Turkish Nationwide Survey Of Glycemic And Other Metabolic Parameters Of Patients With Diabetes Mellitus (Temd Study)
(2018) Bascil Tutuncu, Neslihan; Bozkirli, Emre; https://orcid.org/0000-0002-1644-6790; 30244051; E-9887-2014
Aims: Turkey has the highest prevalence of diabetes in Europe. It is therefore essential to know the overall cardiovascular risk and reveal the predictors of metabolic control in Turkish adults with diabetes mellitus. Methods: A nationwide, multicenter survey consecutively enrolled patients who were under follow up for at least a year. Optimal control was defined as HbA1c <7%, home arterial blood pressure (ABP) <135/85 mmHg, or LDL-C <100 mg/dL. Achieving all parameters indicated triple metabolic control. Results: HbA1c levels of patients (n = 5211) were 8.6 +/- 1.9% (71 +/- 22 mmol/mol) and 7.7 +/- 1.7% (61 +/- 19 mmol/mol), in Type 1 and Type 2 diabetes, respectively. Glycemic control was achieved in 15.3% and 40.2%, and triple metabolic control was achieved in 5.5% and 10.1%, respectively. Only 1.5% of patients met all the criteria of being non-obese, nonsmoker, exercising, and under triple metabolic control. Low education level was a significant predictor of poor glycemic control in both groups. Conclusions: Few patients with Type 2, and even fewer with Type 1 diabetes have optimal metabolic control in Turkey. TEMD study will provide evidence-based information to policy makers to focus more on the quality and sustainability of diabetes care in order to reduce the national burden of the disease.
