Abstract
INTRODUCTION Asprosin is a hormone that was first reported by Romere et al. [2016]. Its secretion is induced in the case of starvation. Asprosin promotes hepatic glucose release. There is no literature information available in humans to demonstrate how blood and saliva asprosin levels of patients with the newly identified type 2 diabetes mellitus (T2DM) changed after metformin treatment. We aim to examine these changes and contribute to the literature in this sense. MATERIAL AND METHODS A total of 60 individuals: 30 healthy volunteers and 30 newly identified cases of T2DM whose treatment had been initiated, were included in the investigation. Blood and saliva sample specimens were carefully taken from both groups. Saliva asprosin and serum levels were tested using the ELISA method. Immunohistochemical methods were used to test asprosin formation sites in salivary gland tissues. RESULTS Similarly increased asprosin levels were observed in patients from the newly diagnosed T2DM group compared with the healthy control group (p = 0.003). In the newly defined T2DM group, blood asprosin levels decreased significantly after three months of metformin treatment (p = 0.032). In terms of saliva asprosin levels, when the healthy control group and the newly identified T2DM group were compared, saliva asprosin levels were found to be higher in the newly identified T2DM group (p < 0.001). With immunohistochemical staining, asprosin immunoreactivity was observed in the submandibular and parotid glands. CONCLUSIONS In our study, serum and saliva asprosin levels increased significantly in the newly identified individuals with type 2 diabetes, which suggests that asprosin could form a critical risk related to T2DM. Higher asprosin levels are an important marker for predicting diabetes development, and that this hormone can be signified as a main or target molecule in the treatment of diabetes.

Abstract
INTRODUCTION Meteorin-like (Metrnl), also known as subfatin, is a recently discovered adipokine with a favourable effect on insulin sensitivity. Studies have shown lower Metrnl levels in obese patients. However, data on its circulating levels in type 2 diabetes mellitus (T2DM) patients are contradictory. This study aims to evaluate serum Metrnl levels in T2DM patients and determine the relationship between serum Metrnl levels and insulin resistance in these patients. MATERIAL AND METHODS This cross-sectional study was conducted among 150 participants. The study was carried out between June 2019 and December 2019 at the internal medicine outpatient clinic of a tertiary university hospital. The participants were divided into three groups: group 1 (control group, n = 50), group 2 (newly diagnosed T2DM, n = 50), and group 3 (long-standing diagnosed T2DM, n = 50). An enzyme-linked immunosorbent assay (ELISA) was used to measure the serum levels of Subfatin (Metrnl), and the correlations of Metrnl level with anthropometric parameters, HOMA index, and biochemical measurements were assessed. RESULTS There was no statistically significant difference between the gender (p = 0.468) and age (p = 0.067) characteristics of the three groups. The Metrnl (subfatin) levels of the participants were as follows: control group - 20.05 (1.56-103.78); newly diagnosed T2DM group - 2.62 (1.25-103.78); and long-standing diagnosed T2DM group - 2.01 (0.80-19.84) pg/mL. The Metrnl (subfatin) levels of the participants in the control group were higher than in the participants in the newly diagnosed T2DM and long-standing diagnosed T2DM groups (p < 0.001). Subfatin demonstrated a negative correlation with insulin and HOMA-IR in the control group and long-standing diagnosed T2DM group. CONCLUSIONS The subfatin level was found to be higher in the healthy control group than in both diabetic patient groups. Subfatin level showed negative correlation with both insulin level and HOMA index. There was a relationship between subfatin and insulin resistance. Low levels of subfatin in the diabetic patient groups may play a role in the pathogenesis of T2DM by increasing insulin resistance.

Abstract
BACKGROUND Elabela (ELA) is a hormone that is secreted at high levels in the kidneys of a healthy adult. This study aims to investigate whether serum ELA levels of patients with Type 2 Diabetes vary with the severity of renal damage. METHODS Our study included 50 healthy control subjects and 100 diabetic patients, who were categorized into groups based on urine albumin/creatinine ratios (ACR). Patients included in the study were assigned to four groups: Group 1 (healthy control), Group 2 (ACR<29mg/g), Group 3 (ACR=30-299 mg/g), and Group 4 (ACR>300 mg/g normal or high serum creatinine). Physical examination findings, demographic characteristics of the study group were recorded, and serum ELA levels and other laboratory parameters were assessed using appropriate methods. RESULTS The results of the study indicated that ELA levels determined in healthy individuals gradually decreased through stages of normal albuminuria, microalbuminuria, and macroalbuminuria. Moreover, ELA had a significant negative correlation with LDL-C (r=-0.201, p=0.014), glucose (r=-0.437, P<0.001), retinopathy (r=-0.222, P=0.006), serum BUN (r=-0.161, P=0.049), and a positive correlation with eGFR (r=0.250, P=0.002). CONCLUSIONS The fact that ELA levels are higher in healthy individuals compared to diabetic patients without microalbuminuria, and higher in diabetic patients without microalbuminuria compared to patients with advanced albuminuria and kidney damage, suggests that the ELA level can be an important clinical prognostic variable and even a promising agent for the treatment of diabetic nephropathy patients.

Abstract
INTRODUCTION Diabetes mellitus (DM) is a primary disease of the carbohydrate metabolism that is characterised by absolute or relative insulin deficiency, or insulin resistance. Although life expectancy is low for diabetic patients, the prognosis has been improved in recent decades. Metformin is an oral antidiabetic that reduces insulin resistance and plasma glucose levels by decreasing glucose production in the liver. It can be used as a standalone treatment or in combination with other antidiabetic medications or insulin. Urotensin 2 (U-II), which is one of the most effective known vasoconstrictor peptides, was observed to act as a vasoconstrictor in diseases such as hypertension and heart failure, and to induce vasodilation in healthy volunteers. Some studies have proposed that the activation of the U-II system could lead to metabolic syndrome. Certain studies have determined a link between DM and U-II. However, there exist no studies on the effects of U-II in recently diagnosed type 2 DM patients after metformin treatment. This study aims to investigate the plasma and saliva levels of U-II at diagnosis and after a three-month metformin treatment in recently diagnosed type 2 DM patients, and to compare these levels to those of healthy volunteers. MATERIAL AND METHODS Our study compared 30 recently diagnosed type 2 DM patients to their states after three-month metformin treatment and 30 healthy volunteers. RESULTS When compared with the control group, there was no significant increase in the plasma and saliva U-II levels of recently diagnosed type 2 DM patients. We determined a statistically significant increase in the plasma and saliva ureotensin-2 levels of recently diagnosed type 2 DM patients after a three-month metformin treatment (p < 0.05). CONCLUSIONS It was concluded that the patients with type 2 DM have a multifactorial aetiopathogenesis and an increase in U-II levels after metformin treatment. Metformin has no known effect on the U-II metabolism; therefore, the findings need confirmation through more clinical and experimental studies with more participants.

Abstract
OBJECTIVE We aimed to investigate the potential relationship between plasma alarin levels and type 2 diabetes mellitus (T2DM). PATIENTS AND METHOD We included 154 participants, divided into four groups in a cross-sectional study design. The first group includes patients with T2DM without complications (n=30), the second group patients with T2DM with microvascular complications (T2DM-noC n=32), the third group patients with T2DM with macrovascular complications, T2DM-MV (n=32) and the last group is the healthy control group (n=60). RESULTS In our study 94 patients were diabetic; 47 females and 47 males. The control group consists of 60 people, 30 women and 30 men. It was found that these had a significant (p>0.05) variation in serum alarin levels among the T2DM (T2DM-noC=3.1±0.7 ng/mL T2DM-mV=2.8±0.4 ng/mL, T2DM-MV= 3.6±0.4 ng/mL) versus control group (15.6±2.6).We failed to find a significant variation of serum alarin levels (p>0.05) between T2DM subgroups. Serum alarin levels were significantly higher among control patients (p<0.05). There was no difference between diabetic sub-groups. CONCLUSION We concluded that serum alarin levels in patients with T2DM are lower than in normal people. Further studies are needed to investigate the possible prognostic value of alarin in clinical practice in T2DM.

Abstract
CONTEXT Bone mineral density is normal in acromegalic patients and the cause of increased fracture risk that characterizes active acromegaly is unknown. OBJECTIVE This study compared serum sclerostin levels between patients with active acromegaly and healthy individuals. DESIGN, SETTING, AND PARTICIPANTS The serum sclerostin levels of patients with active acromegaly were compared with those of healthy volunteers in a cross-sectional study. The mean age of the 30 acromegaly patients (male/female: 14/16) was 47.26 ± 12.52 years (range, 18-64 years) and that of the healthy volunteers (male/female: 17/13) was 44.56 ± 10.74 years (range, 19-62 years). IGF-1 and GH levels were measured using an electrochemiluminescence method, and serum sclerostin levels using an ELISA. The Mann-Whitney U test was used to compare sclerostin levels between the 2 groups. The correlations of sclerostin level with IGF-1 and GH were determined using Spearman's test. RESULTS The 2 groups did not differ in age or sex (P > 0.05). The median GH and IGF-1 levels in the patient group were 2.49 ng/mL (range, 0.22-70.00 ng/mL) (interquartile range [IQR], 1.3-4.52) and 338.5 ng/mL (range, 147-911 ng/mL) (IQR, 250-426), respectively. The median GH and IGF-1 levels in the control group were 0.95 ng/mL (range, 0.3-2.3) and 144 ng/mL (range, 98-198), respectively. The median sclerostin level was 29.95 ng/mL (range, 7.5-78.1 ng/mL) (IQR, 14.37-37.47) in the acromegaly group and 22.44 ng/mL (range, 8.45-36.44 ng/mL) (IQR, 13.71-27.52) in the control group (P < 0.05). There was a moderate positive correlation between the sclerostin and IGF-1 levels (rho = 0.54; P < 0.01), and between the sclerostin and GH levels (rho = 0.41; P < 0.05). CONCLUSIONS High sclerostin levels may contribute to the increased fracture risk seen in patients with acromegaly.

Abstract
Objective To examine potential associations between neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, mean platelet volume (MPV), HbA1c and microvascular complications in diabetic patients from a cost-effectiveness perspective. Methods One hundred patients with type 2 diabetes attending our outpatient unit between May 2018 and October 2018 were included, and 100 healthy individuals served as the control group. A retrospective file search was performed to collect information on hemoglobin, mean platelet volume (MPV), glycosylated haemoglobin (HbA1c), hematocrit (Hct), neutrophil and lymphocyte count, neutrophil/lymphocyte ratio (NLR), platelets (Plt), platelet/lymphocyte ratio (PLR), and microvascular complications (neuropathy, retinopathy, nephropathy). Results Demographic and laboratory data were retrospectively controlled between diabetes (n=100) and healthy control (n=100) groups. The mean age in diabetic patients and healthy controls was 56.34 and 36.68 years, respectively. The mean NLR in diabetics and healthy controls was 2.48 and 2.11, the difference in NLR being significant (p=0.002). MPV in diabetics and controls was 8.54 and 8.53, respectively, and the difference was not significant (p=0.93). PLR was also similar, i.e. 149.7 and 145.3 in diabetics and healthy controls (p=0.067). With respect to microvascular complications, retinopathy was found to be significantly associated with MPV and NLR (p=0.015, and p=0.051), and nephropathy showed a significant association with NLR (p=0.027) among diabetics. In contrast with the two other microvascular complications, no significant association between neuropathy and NLR could be detected, while PLR and neuropathy was significantly associated (p=0.003). Conclusion Microvascular complications may be associated with certain hematologic parameters, as suggested by comparisons both between diabetics and healthy individuals and within the group of diabetic individuals. We believe that hematologic parameters such as hematocrit, MPV, NLR, and PLR, which can be obtained through a simple complete blood count, may be utilized as cost-effective predictors of diabetic microvascular complications. Further prospective studies with larger sample size are required to better delineate these associations.

Abstract
Background The aim of this study was to determine the prognosis of severe disease and treatment approaches of both normal and pregnant, especially in patients with severe pancreatitis due to hypertriglyceridemia. Material/Methods We included 30 patients (20 females and 10 males) in this study whose follow-ups and treatments were performed after a diagnosis of hypertriglyceridemia-induced acute pancreatitis between January 2011 and May 2017. Patient personal information, such as age, sex, pre-treatment and post-treatment triglyceride levels, receipt of anti-hyperlipidemic treatments or plasmapheresis, and family history, were collected from hospital records and patient files. Patients with severe pancreatitis history, score, and prognosis were included to increase the value of our study. Mild and moderate cases were excluded. Results The mean age of the patients was 35±6 years. Twenty-four patients (80%) received an anti-hyperlipidemic treatment before their pancreatitis attacks. Plasmapheresis was performed on 8 patients before their pancreatitis attacks. Eighteen patients (60%) had a family history suggesting familial hypertriglyceridemia. Twelve patients (40%) were pregnant. Conclusions The treatment of hypertriglyceridemia-induced acute pancreatitis was mostly confined to supportive, palliative treatments. However, plasmapheresis is a possible treatment option and should be used in the early stages of this disease. The response to medical treatment and support treatment was better in pregnant patients than in the other patient group, and pregnant patients did not require plasmapheresis.

Abstract
Objective In this study, we determined the relationship between the ambulatory arterial stiffness index (AASI) and clinical and laboratory parameters in patients with acromegaly. Methods Sixty-five patients with acromegaly, who visited to Dicle University Medical Faculty Department of Endocrinology (33 females and 32 males), were included in this study. The study control group consisted of 65 subjects. Demographic and clinical data were recorded. Laboratory data (complete blood count, blood urea nitrogen, creatinine, electrolytes, albumin, lipid profile, growth hormone [GH], insulin-like growth factor-1, and the 75-g oral glucose tolerance test) performed over the last year were evaluated. The AASI was obtained from 24-hour ambulatory blood pressure monitoring records of all patients. This study was completed in 15 months from 2013 to 2015. Results Twelve patients (18.4%) had diabetes and 21 patients (32%) had hypertension. The mean AASI value was 0.41 ± 0.14. The mean AASI value in the control group was 0.25 ± 0.09. Growth hormone (GH) levels were positively correlated with the AASI values. AASI values tended to be higher in hypertensive subjects than that in normotensive individuals. Conclusions Our results show that the AASI value increased in patients with acromegaly, independent of the increase in blood pressure. The AASI was strongly dependent on the degree of the GH increase in patients with acromegaly and may have an important role predicting cardiovascular risk in patients with acromegaly.

Abstract
BACKGROUND The capillary networks are less dense and have irregular structures in scleroderma. These abnormalities result in lower capillary blood flow causing severe tissue hypoxia, which is a major stimulus for angiogenesis. However, current knowledge about compensatory angiogenesis is ambiguous in scleroderma. Bevacizumab is an inhibitor of vascular endothelial growth factor (VEGF). OBJECTIVES The aim of the present study is to evaluate the protective effects of bevacizumab in bleomycin (BLM)- -induced dermal fibrosis. MATERIAL AND METHODS This study involved 4 groups of Balb/c mice (n = 10 per group). Mice in the control group received 100 μL/day of phosphate-buffered saline (PBS) subcutaneously, while the other 3 groups were given 100 μg/day of BLM (dissolved in 100 μL PBS) subcutaneously, for 4 weeks. Mice in BLM-treated 3rd and 4th groups also received bevacizumab (1 or 5 mg/kg twice a week, intraperitoneally). At the end of the fourth week, all mice were sacrificed and blood and tissue samples were obtained. RESULTS The BLM applications increased the dermal thicknesses, tissue hydroxyproline contents, and α-smooth muscle actin-positive (α-SMA+) cell counts, and led to histopathologically prominent dermal fibrosis. The bevacizumab treatments decreased the tissue hydroxyproline contents and dermal thicknesses, and these improvements were more prominent at doses by which α-SMA+ cell counts were markedly decreased, in the BLM-injected mice. CONCLUSIONS In our study, inhibition of VEGF with bevacizumab treatments prevented the BLM-induced dermal fibrosis suggesting that VEGF expression contributes to the pathogenesis of scleroderma.

Abstract
OBJECTIVES The aim of this study was to investigate the relationships between clinical features of rheumatic diseases and hematologic indices, including mean platelet volume (MPV), MPV/platelet ratio (MPR), platelet/lymphocyte ratio, and neutrophil/lymphocyte ratio (NLR). Subjects andMethods: Rheumatoid arthritis (RA; n = 91), systemic lupus erythematosus (SLE; n = 51), systemic sclerosis (SSc; n = 39), and Behçet's disease (BD; n = 53) patients, and 55 healthy controls (HC) were enrolled. Hematological indices were calculated and one-way analysis of variance, Mann-Whitney U and χ2 tests, and receiver operating characteristic (ROC) analyses were performed. RESULTS The MPV and MPR were higher in the SLE group than the RA group (p < 0.05 and p < 0.01, respectively). ROC analysis indicated that MPV (area under the curve, AUC, 0.68, 95% CI 0.58-0.77) and MPR (AUC 0.69, 95% CI 0.59-0.78) were sensitive and specific markers for SLE against RA. The NLR was higher in the RA, SLE, and SSc groups compared to the HC group (p < 0.05, p < 0.001, and p < 0.01, respectively). The NLR was higher in the active BD patients than those that were inactive (p = 0.008). Besides, NLR was higher in patients with neuro-BD and patients with active genital ulcers compared to patients without neurological involvement (p < 0.01) and active genital ulcers (p < 0.05). CONCLUSION The MPV and MPR were significantly higher in the SLE group than in the RA group. They were also higher in the active than in the inactive BD patients. The MPV and MPR are useful diagnostic tools for SLE, and NLR reflects disease activity in BD. However, further research should be performed to standardize these tools.

Abstract
The polyphenol curcumin has several pharmacological effects, including antioxidant, anti-inflammatory and anti-cancer features. In this study, we evaluated the effects of curcumin in cisplatin-induced nephrotoxicity in rats. Male Wistar rats were divided into four groups: (1) control; (2) cisplatin (7 mg/kg body weight, intraperitoneal as a single dose); (3) curcumin (100 mg/kg via gavage, for 10 days); and (4) cisplatin and curcumin. The cisplatin-treated rats exhibited kidney injury manifested by increased serum urea and creatinine (p<0.05). The kidney tissue from the cisplatin treated rats also exhibited a significant increase in the malondialdehyde (MDA) levels (p<0.05). The treatment with curcumin prevented a rise in the serum urea, creatinine and MDA levels when compared to the control group kidneys (p<0.05). The analysis the nicotinamide phosphoribosyltransferase (NAMPT) and sirtuin (SIRT) proteins (SIRT1, SIRT3 and SIRT4), which play important roles in the resistance to stress and the modulation of the threshold of cell death, showed similar trends (p<0.05). In the cisplatin-only treated rats, the induced renal injury decreased the levels of the NAMPT and SIRT proteins. Conversely, the curcumin increased the levels of the NAMPT and SIRT proteins in the cisplatin-treated rats (p<0.05). These data suggest that curcumin can potentially be used to reduce chemotherapy-induced nephrotoxicity, thereby enhancing the therapeutic window of cisplatin.

Abstract
AIMS This experiment investigated if chromium (Cr) as Cr-histidinate (CrHis) and Cr29 picolinate (CrPic) have a protective role in rats with hypoglycemia-induced brain injury, assessed by neuronal plasticity and regeneration potential. MAIN METHODS Male Sprague-Dawley rats were prospectively divided into 2 groups: control and hypoglycemic (induced by insulin administration, 15U/kg, i.p., n=56). Hypoglycemic rats were then received randomly 1) none, 2) dextrose (on the day of sampling), 3) CrHis, or 4) CrPic. Cr-chelates were delivered via drinking water (providing 8μg elemental Cr per day) for one week prior to the hypoglycemia induction. The expressions of neuroplasticity markers [neural cell adhesion molecule (NCAM), growth-associated protein-43 (GAP-43), glial fibrillary acidic protein (GFAP)], glucose transporters (GLUT), and nuclear transcription proteins [nuclear factor-kappa (NF-κB), nuclear factor (erythroid-derived 2)-like 2 (Nrf2), and 4-hydroxyl nonenal (HNE)] were determined using Western blot. KEY FINDINGS Hypoglycemia caused increases in the expressions of GLUT-1, GLUT-3, GFAP, NF-κB and HNE and decreases in the expression of NCAM's, GAP-43 and Nrf2 in the hippocampus, cerebellum, and cortex. Cr-chelates suppressed expressions of GLUTs, GFAP, NF-κB and HNE expressions and enhanced expressions of NCAM, GAP-43 and Nrf2, which were more notable for CrHis than for CrPic. SIGNIFICANCE In conclusion, hypoglycemia leads to cerebral injury and Cr-chelates, particularly CrHis have protective and regeneration potential in cerebral tissues through modulating neuroplasticity markers and nuclear transcription proteins as well as facilitating glucose transporters.

Abstract
Hepatitis delta virus (HDV) is a serious cause of liver-related morbidity and mortality. Coexistent infection with HDV tends to aggravate the course of hepatitis B virus (HBV)-associated liver disease. The aim of this study was to determine the prevalence of HDV infection among patients chronically infected with HBV in the Elazig region, which is in eastern Turkey. A group of 282 patients infected with chronic HBV were investigated for the study. Anti-HDV seropositivity was evaluated in all patients. The anti-HDV-positive patients were further tested for HDV RNA. Severity of liver disease was assessed by liver biopsy. Regression analysis was used to determine the relationship between independent variables and HDV positivity. Of 282 chronic HBV patients, 192 were men (68.1%) and 90 were women (31.9%). The mean age was 43.8 ± 12.7 (between 18 and 73 years). Anti-HDV was positive in 45.5% of the patients (128/282). Among the 128 anti-HDV-positive patients, 116 were checked for HDV RNA and 56.9% were found positive (66/116). Chronic HDV infection rate was therefore present in at least 23.4% of the whole study group (66/282). There were 83 patients with cirrhosis (29.4%) in the study group. Anti-HDV seroprevalence and HDV RNA presence were higher in those with cirrhosis (61.4% and 42.2%, respectively). No significant relationship was found between anti-HDV seropositivity and demographic factors such as age, sex and operation or transfusion history except family history. HDV-RNA-positive patients had significantly higher ALT and lower albumin levels when compared to HDV-RNA-negative patients. HDV-RNA-positive patients also had a significantly higher fibrosis stage. In conclusion, these findings demonstrated that HDV infection is endemic and still a serious problem in the Elazig region of eastern Turkey. HDV infection is significantly related to the family exposure and increases the risk of severe liver fibrosis in this region.
