Abstract
BACKGROUND Inflammation occurring after vascular endothelial damage plays a role in thrombus formation. Changes in various blood parameters that develop after the inflammatory condition can be used as a marker to predict thrombus. AIM This study aimed to investigate the relationship between the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and portal vein thrombosis (PVT). MATERIALS AND METHODS After applying the exclusion and inclusion criteria to the patients diagnosed with PVT and followed up in our center between January 2006 and May 2018, a total of 38 patients without acquired risk factors for the development of PVT and 52 healthy controls were included in the study. Clinical features and NLR and PLR at diagnosis were evaluated. RESULTS NLR and PLR values were detected to be significantly higher in patients diagnosed with PVT compared to the control group (P < 0.001 for NLR, P < 0.001 for PLR). Findings were as follows: In acute PVT patients for NLR = 3.645 (area under the receiver operating characteristic (AUROC) 0.886, sensitivity 69.2%, specificity 96.2%, P < 0.001), for PLR = 196.24 (AUROC 0.754, sensitivity 53.2%, specificity 96.2%, P = 0.005), while in chronic PVT patients, for NLR = 3.645 (AUROC 0.744, sensitivity 40%, specificity 96.2%, P = 0.001), and for PLR = 195.93 (AUROC 0.715, sensitivity 44%, specificity 96.2%, P = 0.002). CONCLUSION NLR and PLR were associated with the diagnosis of PVT. In PVT patients, NLR and PLR values were observed to be significantly higher than the control group. In our study, the relationship between NLR and PLR in patients with noncirrhotic, nonmalignant PVT without acquired risk factors for thrombosis was shown for the first time.

Abstract
Background and Aim The aims of the present study were to evaluate the real-life efficacy and tolerability of glecaprevir (GLE)/pibrentasvir (PIB) in the treatment of patients with chronic hepatitis C (CHC). Materials and Methods Between May 2019 and May 2022, 686 patients with CHC, treated with GLE/PIB combination from 21 participating centers in Turkiye, were enrolled in the study. Results All patients were Caucasian, and their median age was 56 years. At the start of GLE/PIB treatment, the median serum Hepatitis C virus RNA and serum alanine amino transaminase (ALT) levels were 6.74 log10 IU/mL and 47 U/L, respectively. Fifty-three percent of the patients were infected with genotype 1b, followed by genotype 3 (17%). Diabetes was the more common concomitant disease. The sustained virological response (SVR12) was 91.4% with intent-to-treat analysis and 98.5% with per protocol analysis. The SVR12 rates were statistically significant differences between the patients who were i.v. drug users and non-user (88.0% vs. 98.8%, p=0.025). From the baseline to SVR12, the serum ALT levels and Model for End-Stage Liver Disease score were significantly improved (p<0.001 and p=0.014, respectively). No severe adverse effect was observed. Conclusion GLE/PIB is an effective and tolerable treatment in patients with CHC.

Abstract
Aims and Background Suppressor of cytokine signaling 1 (SOCS1) is a prototype molecule of the SOCS family. Alterations in the SOCS1 expression have been reported in human cancers and some studies suggest that SOCS1 might act as a tumor suppressor in carcinogenesis. In the present study, we aimed to evaluate the association of SOCS1 promoter -1478CA/del gene polymorphism detected in DNA isolated from the tissues of patients with colorectal cancer (CRC) for histopathological characteristics and survival. Patients and Methods For the study, we retrospectively enrolled 53 patients with resected colon due to CRC and 23 control subjects with no systemic illness. SOCS1- 1478CA/del gene polymorphism was determined using the polymerase chain reaction-restriction fragment length polymorphism methodology. These results were evaluated in relation to histopathological features and survival results and analyzed statistically. A P value equal to or less than 0.05 was considered significant. Results Neither control subjects nor the CRC group showed a significant association with SOCS1 -1478CA/del gene polymorphism (p = 0.248). SOCS1 -1478CA/del gene polymorphism was not significantly associated with histopathological features either. However, in the overall survival (OS) analysis, those patients with the del/del allele were found to have a 3.9-fold greater risk of mortality compared to those with CA/CA allele (p = 0.05). Progression-free survival (PFS) was also significantly different in such patients (p = 0.05). Conclusion The present study examining the association of SOCS1 -1478CA/del gene polymorphism with CRC showed that CRC patients with del/del allele had both significantly shorter PFS and OS versus those with CA/CA or CA/del allele.

Abstract
Background Adiponectin (ApN) is a 244-amino acid protein mainly secreted from the adipose tissue and involved in various physiological functions. ApN exerts its metabolic effects by binding to two major receptors: adiponectin receptor-1 (Adipo-R1) and adiponectin receptor-2 (Adipo-R2). Recent studies have reported ApN's involvement in the progression of cancer. However, there are no studies evaluating the relationship between Adipo-R1/R2 expression and gastric intestinal metaplasia (IM), which is a predisposing factor in gastric cancer (GC) development, and Helicobacter pylori H. pylori infection. Aims In this study we aimed to investigate the relationship between the Adipo-R1/-R2 expression and H. pylori infection in patients with GC and gastric IM. Materials and Methods Forty patients that underwent gastric resection and 56 patients that developed gastric IM were included in the study. The Adipo-R1/-R2 expression and the presence of H. pylori were examined immunohistochemically. The univariate analyses showed that the expression of Adipo-R1/-R2 in GC patients was significantly lower compared to both complete metaplasia (CM) and incomplete metaplasia (ICM) patients (p <0.0001 for both). Results According to multiple multinomial logistic regression analysis, Adipo-R1/-R2 expression in the CM group was significantly higher than in the GC group (p = 0.05, p = 0.014, respectively). Moreover, Adipo-R1/-R2 expression was significantly higher in ICM group compared to the GC group (p=0.012, p=0.045, respectively). However, in both analyses no significant difference was determined in terms of H. pylori positivity between the groups. Conclusion The resulting data suggests that ApN plays a role in GC processes via Adipo-R1/-R2 receptors.

Abstract
Objective: This study aimed to compare the performances of the Glasgow–Blatchford Bleeding Score (GBS), pre-endoscopic Rockall score (PRS), complete Rockall score (CRS), and Cedars–Sinai Medical Center Predictive Index (CSMCPI) in predicting clinical outcomes in patients with upper gastrointestinal bleeding (UGIB). Methods: Patients who were admitted to the emergency department because of UGIB and underwent endoscopy within the first 24 hour were included in this study. The GBS, PRS, CRS, and CSMCPI were propectively calculated. The performances of these scores were assessed using a receiver operating characteristic curve. Results: A total of 153 patients were included in this study. For the prediction of high-risk patients, area under the curve (AUC) was obtained for GBS (0.912), PRS (0.968), CRS (0.991), and CSMCPI (0.918). For the prediction of rebleeding, AUC was obtained for GBS (0.656), PRS (0.625), CRS (0.701), and CSMCPI (0.612). For the prediction of 30-day mortality, AUC was obtained for GBS (0.658), PRS (0.757), CRS (0.823), and CSMCPI (0.745). Conclusion: These results suggest that effectiveness of CRS is higher than that of other scores in predicting high-risk patients, rebleeding and 30-day mortality in patients with UGIB.

Abstract
BACKGROUND The mean platelet volume (MPV) is the most commonly used measure of platelet size and is a potential marker of platelet reactivity. In this study, we aimed to explore the relationship between hepatic histopathology in viral hepatitis and MPV levels, which are associated with platelet count and activity. MATERIALS AND METHODS We performed a retrospective case-control study of baseline histological and clinical parameters in chronic hepatitis B and C patients in our tertiary reference center between January 2005 and January 2011. Two hundred and five chronic hepatitis B patients and 133 chronic hepatitis C patients who underwent liver biopsy were included in the study. The patients were divided into two groups: Chronic hepatitis B and chronic hepatitis C and were additionally divided into groups of two according to histological activity index (HAI) and fibrosis scores obtained by liver biopsy results (according to the Ishak scoring system). The clinical characteristics of chronic viral hepatitis patients, including demographics, laboratory (especially MPV), and liver biopsy findings, were reviewed. RESULTS One hundred and forty-three patients were male (69.1%), and the mean age was 41.9 ± 12.75 with an age range of 18-71 years in hepatitis B patients. In the classification made according to HAI, 181 patients were in the low activity group (88.3%) and 24 in the high activity group (11.7%). In the evaluation made according to fibrosis score, 169 patients were found to have early fibrosis (82.4%) and 36 were found to have advanced fibrosis (17.6%). In patients with hepatitis B, there was no statistically significant difference in terms of their MPV values between the two groups, separated according to their degree of activity and fibrosis. Sixty-three patients were male (47.3%), and the mean age was 50.03 ± 12.75 with an age range of 19-75 years. In the classification made according to HAI, 109 patients were in low activity group (81.9%) and 24 in high activity group (18.1%). In the evaluation made according to fibrosis score, 101 patients were found to have early fibrosis (75.9%) and 32 have advanced fibrosis (24.1%). There was a statistically significant difference between the activity and fibrosis groups of the hepatitis C patients (P = 0.04 and P = 0.02, respectively). CONCLUSION MPV values are more reliable in hepatitis C patients than hepatitis B for predicting the advanced damage in liver histology. This finding might be useful for the detection of early fibrosis and also starting early treatment, which is important in hepatitis C.

Abstract
BACKGROUND/AIMS To investigate the relationship between gamma-glutamyl transpeptidase (GGT) levels and histopathological status determined by biopsy in patients with chronic hepatitis B and C. MATERIALS AND METHODS Patients with chronic hepatitis B and C who were referred to the Uludağ University Faculty of Medicine Gastroenterology outpatient clinic between January 2005-January 2011 and underwent liver biopsy were included in the study. Overall, 246 patients with hepatitis B and 151 patients with hepatitis C were enrolled. According to the evaluation based on the Ishak score, patients with a histological activity index (HAI) between 0-12 were defined as low activity, and those with an HAI between 13-18 were defined as high activity. In addition, patients with a fibrosis score of 0-2 were defined as low fibrosis, and those with a score between 3-6 were defined as high fibrosis; comparisons were made accordingly. RESULTS In patients with hepatitis B, the mean GGT level was 38.86±42.4 (IU/L) in the low activity group and 60.44±44.4 (IU/L) in the high activity group (p<0.05). In hepatitis B patients, the mean GGT level was 26.89±14.83 (IU/L) in the low fibrosis group, whereas it was 65.60±59.7 (IU/L) in the high fibrosis group (p<0.001). There was no significant difference between HAI and fibrosis group with regard to GGT levels in the hepatitis C patients. CONCLUSION In conclusion, it is proposed that in patients with chronic viral hepatitis, GGT levels can be taken into consideration to predict advanced histological liver damage, especially in patients with hepatitis B.

Abstract
BACKGROUND Human adiponectin (ApN), a 30 kDa glycoprotein of 244-amino acids which is predominantly produced by adipocytes, exerts its effects via two receptors, namely adiponectin receptor-1 (adipo-R1) and adiponectin receptor-2 (adipo-R2) with differential binding affinity to globular adiponectin. Adiponectin receptor expression has been studied in several cancer tissues. However, there are no studies of colorectal adenomas which are considered to be precursors for colorectal carcinoma (CRC). OBJECTIVES In the present study, the expression of adipo-R1 and adipo-R2 was investigated immunohistochemically in colorectal adenomas and colorectal carcinoma tissues in an attempt to determine associations with these tumors. MATERIALS AND METHODS The study enrolled 50 CRC patients with tumor resection and 82 patients who were diagnosed with adenomatous polyps, classified as negative for neoplasia, low-grade dysplasia (L-GD) or high- grade dysplasia (H-GD). RESULTS Expression of both adipo-R1 and adipo-R2 was found to be significantly lower in the CRCs than in colorectal adenomas (tubular and tubulovillous, p=0.009 and p<0.001, respectively). Adipo-R1 and adipo-R2 expression was also significantly lower in the CRC group when compared with the groups of patients with low grade dysplasia, high-grade dysplasia or no neoplasia (p=0.012 and p<0.001, respectively). In addition, it was observed that adipo-R2 expression was generally positive in the non-neoplastic group irrespective of the adipo-R2 expression. In the L-GD, H-GD and CRC groups, the adipo-R2 result was positive whenever adipo-R1 result was positive but some patients with negative adipo-R1 had positive adipo-R2 (p<0.001, p=0.004, p<0.001, respectively). CONCLUSIONS This study indicated that ApN may play a role in the progression of colorectal adenomatous polyps to carcinoma through actions on adipo-R1 and adipo-R2 receptors.

Abstract
INTRODUCTION Human adiponectin (ApN) is a 30 kDa glycoprotein of 244-amino acids which is extensively produced by adipocytes. ApN acts via two receptors, namely adiponectin receptor-1 (Adipo-R1) and adiponectin receptor-2 (Adipo-R2). Studies have shown the presence of Adipo-R1 and Adipo-R2 expression immunohistochemically in human colorectal cancers (CRCs). However, only a few studies exist which investigated effects of adiponectin receptor expression on CRC characteristics. OBJECTIVES In the present study, we aimed to explore Adipo-R1/-R2 expression in human colorectal cancers and any association with clinicopathological characteristics and survival. MATERIALS AND METHODS The study enrolled 58 colorectal cancer patients with tumor resection and a control group of 30 subjects with normal colon mucosa. RESULTS Positivity for Adipo-R1/-R2 expression was significantly more common in the control group in comparison to the patient group (both p<0.001). There was no significant association between Adipo-R1/-R2 expression and clinicopathological characteristics including age, sex tumor location, pTNM stage, Duke's stage, metastasis, histological differentiation, perineural invasion, venous invasion sex, lymphatic invasion, cancer-related mortality, tumor size and recurrence. Adipo- R1/-R2 positivity was also not significantly linked to progression-free or overall survival [p values (0.871, 0.758 ) and (0.274, 0.232), respectively]. CONCLUSIONS Although significantly reduced Adipo-R1/-R2 expression was found in colorectal cancer patients, it had no influence on survival.

Abstract
INTRODUCTION Recent studies have indicated that down-regulation of the suppressor of cytokine signaling-1 (SOCS-1) gene results in tumor formation and that SOCS-1 acts as a tumor suppressor gene. SOCS-1 has been also suggested to function as a tumor suppressor with colorectal cancer. OBJECTIVES In the present study, we aimed to determine the association of SOCS-1 expression in colorectal cancer tissues with clinicopathologic characteristics immunohistochemically and also to identify its prognostic significance. MATERIALS AND METHODS SOCS-1 expression was studied immunohistochemically in 67 patients diagnosed with resected colorectal carcinomas and 30 control subjects. RESULTS SOCS-1 expression was found in 46.3% of tumor tissues and 46.7% of the control group. Statistical analyses did not establish any significant association between SOCS-1 expression and clinicopathologic characteristics. Also, no significant association with SOCS-1 expression was found using progression-free survival and overall survival analyses (p=0.326 and p=0.360, respectively). CONCLUSIONS Our results show that SOCS-1 has no prognostic significance in colorectal cancer.

Abstract
INTRODUCTION Adiponectin (ApN) is a complement C1q-related protein, mainly secreted from adipose tissue, that signals through ApN receptor 1 (Adipo-R1) and ApN receptor 2 (Adipo-R2). Low serum ApN concentrations are associated with obesity-related malignancies. However, there are very few studies on any prognostic role of ApN receptors in gastric cancer. OBJECTIVES The aim of this study is to investigate the relationship between AdipoR1/R2 expression and early/advanced stage gastric cancer in terms of clinicopathologic characteristics and survival. MATERIALS AND METHODS Eighteen patients with early and 39 with advanced stage gastric cancer who underwent surgical gastric resection were included in this study. RESULTS Adipo-R1 expression was low in 2 of the 18 patients with early stage gastric cancer (11.1%), while 4 had low Adipo-R2 expression (22.2%). In those with advanced stage gastric cancer, 7 of 39 had low Adipo-R1 expression (17.9%) and 16 had low Adipo-R2 expression (41%). Adipo-R2 expression was significantly higher (p=0.011) in moderately differentiated tumors when compared to well-differentiated tumors. While there was nearly a statistically significant relationship between TNM stage (T, tumor size; N, regional lymph node; M, whether distant metastases exist) and Adipo-R2 expression (p=0.054), there was no relationship between Adipo-R1/-R2 expression with tumor stage and survival. CONCLUSION Adipo-R1/-R2 expression has no prognostic significance of in early/advanced stage gastric cancer.

Abstract
Background/Aims We sought to examine whether the presence of gallstone disease (GD) in patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD) is associated with liver fibrosis and histological nonalcoholic steatohepatitis (NASH) score. Methods We included 441 Turkish patients with biopsy-proven NAFLD. GD was diagnosed in the presence of sonographic evidence of gallstones, echogenic material within the gallbladder with constant shadowing and little or no visualization of the gallbladder or absence of gallbladder at ultrasonography, coupled with a history of cholecystectomy. Results Fifty-four patients (12.2%) had GD (GD+ subjects). Compared with the GD- subjects, GD+ patients were older, had a higher body mass index and were more likely to be female and have metabolic syndrome. However, GD+ patients did not have a higher risk of advanced fibrosis or definite NASH on histology. After adjustment for potential confounding variables, the prevalence of GD in NAFLD patients was not associated with significant fibrosis (≥2) (odds ratio [OR], 1.06; 95% confidence interval [CI], 0.53 to 2.21; p=0.68) or definite NASH (OR, 1.03; 95% CI, 0.495 to 2.12; p=0.84). Conclusions The presence of GD is not independently associated with advanced fibrosis and definite NASH in adult Turkish patients with biopsy-proven NAFLD.

Abstract
Objective This study presented the demographic, clinical and laboratory data for the patients who presented to our emergency department (ED) with mushroom poisoning. Methods We retrospectively examined the data for adult patients with mushroom poisoning that presented to the ED of Uludag University, Faculty of Medicine between 1 January 2007 and 31 December 2010. Results A total of 53 patients were enrolled in the study. The mean age was 46.58±15.47. 52.8% of the patients were female, while 47.2% were male. These patients were typically admitted in the autumn. The most commonly seen symptoms were gastrointestinal such as nausea and vomiting. The time to symptom onset was <6 hours for 30.2% of the patients and >6 hours in 69.8% of the patients. While 73.5% of the patients received gastric lavage, activated charcoal and intravenous fluid therapy, 15.1% received penicillin, N-acetylcysteine and intravenous fluid therapy. For the remaining patients (11.4%) silibinin, dialysis and plasmapheresis were administered. While 35.8% of the patients were hospitalised, 64.2% were discharged from the ED. The median duration of stay in the ED was 6 hours (range: 1-27 hours); the median duration of stay among inpatients was 6 days (range: 1-36 days). Three of the hospitalised patients died, and two underwent hepatic transplantation. Conclusions Mushroom poisoning remains an important issue that is encountered in rural areas during the rainy autumn season in our region. The condition may be fatal, but can be prevented by early and appropriate treatment.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome (MS). However, not all patients with the MS will develop NAFLD and not all patients with NAFLD have the MS. We sought to investigate the differences between patients with biopsy-proven NAFLD with and without the MS. METHODS A total of 357 consecutive patients with biopsy-proven NAFLD were analysed. Of them, 216 patients had nonalcoholic steatohepatitis (NASH) and 96 a fibrosis score ≥ 2. The MS was defined as ≥ 3 of the ATP III criteria. RESULTS A total of 214 patients with NAFLD met the criteria for the MS, while the remaining 143 did not. In NAFLD patients with the MS, homeostasis model of insulin resistance (P = 0·03; OR, 1·06; 95% CI, 1·023-1·25 per unit increase) and diabetes (P = 0·01; OR, 1·2; 95% CI, 1·1-2·4) were independent predictors of NASH. In NAFLD patients without the MS, the only variable independently associated with NASH was haemoglobin (P = 0·007; OR, 1·9; 95% CI, 1·4-3·6 per 50 g/L increase). Alanine aminotransferase (P = 0·03; OR, 1·04; 95% CI, 1·006-1·11 per 10 U/L increase) was an independent predictor of fibrosis ≥ 2 in NAFLD patients with the MS, while haemoglobin (P = 0·02; OR, 1·4; 95% CI, 1·2-1·9 per 50 g/L increase) was the only variable significantly associated with fibrosis ≥ 2 in NAFLD patients without the MS. CONCLUSIONS Increased haemoglobin in NAFLD subjects without MS should be considered in the selection of cases for histological assessment.

Abstract
Cyclooxygenase-2 (COX-2) is upregulated in gastric carcinoma, and its increased levels were found to have a prognostic significance in some studies. Both angiogenesis and Helicobacter pylori infection have been reported to be associated with COX-2 expression of gastric cancer in recent studies. In this study, COX-2 expression and its association with CD31 staining, H.-pylori infection, and well-known clinicopathological factors were investigated in 65 gastric cancer patients. COX-2 and CD31 expression assessment was done by immunohistochemical methods. Whartin Starry stain was performed for H.-pylori infection. Of 65 patients, 32 (49%) revealed intense COX-2 immunostaining. Among various clinicopathologic characteristics, COX-2 expression was inversely correlated with tumor size, TNM stage, and lymph node status. Thirty-two (49%) patients revealed intense CD31 immunostaining. Among various clinicopathologic characteristics, CD31 expression was associated only with lymph node metastasis. COX-2 expression was not correlated with CD31 staining and H.-pylori infection. Both COX-2 and CD31 staining had no prognostic significance. In conclusion, we found that COX-2 expression was significantly higher in earlier stages of gastric cancer. It can be suggested that COX-2 expression may be important in the initial development of gastric cancer but not in progression of the disease. Other factors which may be associated with COX-2 in gastric cancer, including angiogenesis and H.-pylori infection, should be investigated in further studies.

Abstract
The etiopathogenesis of inflammatory bowel disease remains unclear, with various extraintestinal features often found with the disease. Sometimes more than one extraintestinal finding is found in the same patient. In this case report, a patient with more than one extraintestinal manifestation of Crohn's disease is presented. Extensive thrombi in the venous system and pyoderma gangrenosum in the left lower extremity was observed but there was complete recovery following treatment with both systemic and topical agents.
