Öğe Alstrom syndrome with liver cirrhosis: First case from Turkey(Turkish Soc Gastroenterology, 2013) Biyik, Murat; Ucar, Ramazan; Gungor, Gokhan; Ozer Cakir, Ozlem; Esen, Hasan; Aksan, Serkan; Ataseven, HuseyinAlstrom syndrome is a rare autosomal recessive genetic disorder characterized by cone-rod dystrophy, hearing loss, childhood truncal obesity, insulin resistance and hyperinsulinemia, type 2 diabetes, hypertriglyceridemia, short stature in adulthood, cardiomyopathy, and progressive pulmonary, hepatic, and renal dysfunction. Alstrom syndrome is a very rare cause of liver cirrhosis. Post-mortem biopsies of patients with Alstrom syndrome show relevant fibrosis in multiple organs especially in the liver, kidneys, heart, and lungs. We report the case of a patient with Alstrom syndrome who presented to emergency department with esophageal variceal bleeding and who was not known to have hepatic cirrhosis before.Öğe Are Pattern Recognition Receptors Associated with Hepatocellular Carcinoma?(Aves, 2021) Dertli, Ramazan; Asil, Mehmet; Biyik, Murat; Karakarcayildiz, Ahmet; Keskin, Muharrem; Kayar, Yusuf; Basdemirci, MuserrefBackground: Hepatocellular carcinoma (HCC) is one of the important causes of mortality due to malignancy. Toll-like receptors (TLRs) are very important in liver pathophysiology in terms of their roles in the innate immune system, such as the regulation of inflammation, wound healing, stimulation of adaptive immune responses, promotion of epithelial regeneration, and carcinogenesis. In this study, we planned to examine the role of TLR1 (rs4833095, rs5743551) and nucleotide-binding oligomerization domain (NOD2) (rs2066844, rs2066845, rs2066847) polymorphisms in the development of HCC and their effects on the clinical presentation of HCC patients. Methods: Our study was designed prospectively. Cirrhotic and HCC patients who were followed up in our clinic between January 2015 and September 2018 were included in the study. Sex, age, cirrhosis etiology, Child-Pugh class, and MELD scores were recorded. TLR1 and NOD2 polymorphisms were studied by the PCR method. Results: HCC developed in 88 (31.4%) of the 280 patients who were followed up, either during the recruitment phase of our study or during the follow-up. The mean follow-up time of our patient group was 17.04 +/- 11.72 months, and the mean follow-up time of HCC patients was 12.09 +/- 10.26 months. TLR1 (rs5743551) polymorphism was associated with HCC development (P =.003). TLR1 (rs5743551) and NOD2 (rs2066844) polymorphisms were associated with the development of spontaneous bacterial peritonitis (SBP) in the HCC patient group (P =.013 and P =.021, respectively). Conclusion: We think that increased bacterial translocation in cirrhotic patients may contribute to HCC development by causing chronic inflammation, especially in patients with TLR 1 (rs5743551) polymorphism.Öğe Authors' Reply to the Letter to the Editor: Comprehensive Assessment of Inflammatory Indices to Predict Outcomes in Acute Pancreatitis(Taylor & Francis Inc, 2023) Biyik, Murat; Asil, Mehmet; Keskin, Muharrem; Biyik, Zeynep[Abstract Not Availabe]Öğe Can Hematological Inflammatory Parameters Predict Mortality in Hepatocellular Carcinoma?(Springer, 2021) Dertli, Ramazan; Asil, Mehmet; Biyik, Murat; Karakarcayildiz, Ahmet; Keskin, Muharrem; Goktepe, Hakan Mevlut; Kayar, YusufPurpose Hepatocellular carcinoma (HCC) is one of the most common malignant tumors. Inflammatory and hematological parameters such as neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) provided useful information especially in the diagnosis, treatment, and follow-up of malignancies. In this study, we planned to demonstrate the efficacy of NLR and PLR levels in the evaluation of the prognosis of patients with HCC in our clinic. Material and Methods This study was planned as a prospective observational cohort study. The study included 105 patients with HCC on the base of cirrhosis. Our study group was classified according to Barcelona Clinic Liver Cancer (BCLC), Okuda staging system, and Milan criteria at the time of admission. Results The mean age of all cases was 60.6 +/- 12.4 years, and 77 (73.3%) of the patients were male. The mean life expectancy of all patients was 7.7 +/- 4.3 months. During 1-year follow-up, 61 (58.1%) HCC patients died. The mean survival of the patients who died was 4.6 +/- 3.0 months. In our study, patients with NLR > 2.7, patients with PLR > 100.29, BCLC advanced stage, and Okuda advanced stage, and patients who did not meet the Milan criteria had shorter survival duration. NLR > 2.7, BCLC advanced stage, and Child C were determined as independent risk factors affecting mortality. Conclusion There was a strong correlation between NLR-PLR levels and mortality. PLR and NLR levels can be used in conjunction with other staging systems to regulate, monitor, and predict the survival of HCC patients.Öğe Can neutrophil-lymphocyte ratio predict mortality in acute non-variceal upper gastrointestinal bleeding?(Turkish Assoc Trauma Emergency Surgery, 2022) Dertli, Ramazan; Toka, Bilal; Asil, Mehmet; Kayar, Yusuf; Karakarcayildiz, Ahmet; Goktepe, Mevlut Hakan; Biyik, MuratBACKGROUND: Acute non-variceal upper gastrointestinal bleeding (NVUGIB) is one of the common gastrointestinal problems and has a high mortality, especially in patients with poor hemodynamics. Therefore, treatment and follow-up should be managed dynamically. Neutrophil-lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR) are fast workable, cheap, and easy to calculate hematological parameters. We need easily accessible parameters as well as routine classifications such as Rockall score in the treatment and follow-up of NVUGIB patients, whose hemodynamics are unstable and progress with high mortality. In this study, we planned to evaluate NLR and PLR levels in patients with NVUGIB in the treatment follow-up with other scoring systems and their relationship with mortality in these patients. METHODS: Two hundred and forty-nine patients who were admitted to our clinic between January 2015 and January 2017 diagnosed with NVUGIB, and who underwent necessary examinations and follow-ups, were included in the study. The patients' Glasgow Blacthford, Rockall Score, NLR, and PLR levels were calculated at the first admission. RESULTS: One hundred and fifty-six of the patients were male (70.6%) and the mean age of all patients was 64.5 +/- 18.0 years. After follow-up and treatment, 28 (11.2%) patients died due to bleeding. High NLR and tachycardia at the time of admission and high patient age were found to be independent risk factors affecting the long of hospital stay. High Rockall score, high NLR at admission, and hypotension at admission were shown to be independent risk factors affecting mortality. CONCLUSION: Besides the use of various scoring systems in patients with NVUGIB, we think that the use of simple hematological parameters may be appropriate and the use of these hematological parameters may be useful in the management of patients with unstable hemodynamics.Öğe Can neutrophil-lymphocyte ratio predict mortality in acute non-variceal upper gastrointestinal bleeding?(Turkish Assoc Trauma Emergency Surgery, 2022) Dertli, Ramazan; Toka, Bilal; Asil, Mehmet; Kayar, Yusuf; Karakarcayildiz, Ahmet; Goktepe, Mevlut Hakan; Biyik, MuratBACKGROUND: Acute non-variceal upper gastrointestinal bleeding (NVUGIB) is one of the common gastrointestinal problems and has a high mortality, especially in patients with poor hemodynamics.

Plasma thiols are major defense mechanisms against oxidative stress and undergo oxidation to form disulfides under oxidative conditions. This study was conducted to investigate thiol-disulfide homeostasis in NAFLD patients. Methods: Thirty patients with biopsy proven non-alcoholic steatohepatitis (NASH), 40 patients with simple steatosis and 50 healthy controls were included in the study. Serum total and native thiol concentrations and serum disulfide concentration were measured using the Erel and Neselioglu's method. Results: The mean serum total thiol concentrations in the NASH, simple steatosis and control groups were 415 +/- 64 mu mol/L, 447 +/- 38 mu mol/L and 480 +/- 37 mu mol/L, respectively (p < 0.001). The mean serum native thiol concentrations in the NASH, simple steatosis and control groups were 378 +/- 62 mu mol/L, 416 +/- 41 mu mol/L and 451 +/- 36 mu mol/L, respectively (p < 0.001). The mean serum disulfide concentrations in the NASH, simple steatosis and control groups were 18.5 +/- 6.3 mu mol/L, 15.5 +/- 4.8 mu mol/L and 14.9 +/- 3.6 mu mol/L, respectively (p = 0.005). The native thiol/total thiol ratio was significantly lower and the disulfide/total thiol and disulfide/native thiol ratios were significantly higher in the NASH group than in the simple steatosis and control groups. Conclusions: Thiol-disulfide homeostasis is disturbed and shifted toward disulfide side in NAFLD and NASH patients.Öğe Dynamic thiol-disulfide homeostasis is disturbed in patients with non-alcoholic fatty liver disease(Walter De Gruyter Gmbh, 2018) Asil, Mehmet; Dertli, Ramazan; Biyik, Murat; Yolacan, Ramazan; Erel, Ozcan; Neselioglu, Salim; Ataseven, HuseyinBackground: Oxidative stress has been implicated in the pathogenesis of non-alcoholic fatty liver disease (NAFLD).

Emergency liver transplantation was decided for the case of a 48-year-old male patient, who at the same time had renal failure and acute pancreatitis. Bridge treatment with plasma diafiltration was applied until the liver transplantation, which was successfully performed on the fifth day of admission to the hospital. Acute pancreatitis and renal failure also resolved and the patient was discharged in a healthy condition on the 30th day of admission. The timing of the transplant in fulminant liver failure and criteria used to select the timing are particularly important. Transplantation should be performed not too early, nor too late. In addition, the development of multiple organ failure during the period until transplantation may result in the death of the patient. Therefore, extra corporeal liver support systems are suggested as an important treatment tool at this stage.Öğe Fulminant Liver Failure Due to Amanita Phalloides Toxicity Treated with Emergent Liver Transplantation(Modestum Ltd, 2015) Gok, Funda; Topal, Ahmet; Hacibeyoglu, Gulcin; Erol, Atilla; Biyik, Murat; Kucukkartallar, Tevfik; Yosunkaya, AlperThe clinical picture secondary to amanita phalloides, which began with gastrointestinal complaints, advanced to fulminant hepatic failure in two days.

Recent reports linked PPI use with development of hypomagnesemia. However, there is still uncertainty regarding risk of hypomagnesemia in outpatients who were on long-term PPI use. Thus, we aimed to evaluate frequency of hypomagnesemia among a well-defined outpatient patient cohort with no other possible risk factors affecting serum magnesium levels. This was a case-control study carried out at the outpatient gastroenterology clinic of a University hospital. Patients who were on PPI therapy for at least 6 months without diuretic use and chronic kidney disease were included. Patients who were subjected to the same inclusion and exclusion criteria and not using PPI were included as control subjects. One hundred fifty-four patients and 84 control subjects were included. The mean duration of PPI use was 27.5 +/- 2.5 months. Mean serum magnesium levels of PPI users and nonusers were 2.17 +/- 0.20 mg/dL and 2.19 +/- 0.15 mg/dL, respectively. None of the patient had a serum magnesium level below laboratory lower range of 1.7 mg/dL. Our results showed that for typical gastroenterology outpatient clinic patients with no other risk factors affecting serum magnesium levels, long-term PPI use did not affect serum magnesium levels.Öğe IRRITABLE BOWEL SYNDROME PREVALENCE IN PATIENTS WITH FAMILIAL MEDITERRANEAN FEVER(Carbone Editore, 2015) Kucuk, Adem; Biyik, Murat; Solak, Yalcin; Ucar, Ramazan; Polat, Ilker; Pektas, Fatih; Gungor, GokhanIntroduction: Patients with Familial Mediterranean Fever (FMF) and Irritable bowel syndrome (IBS) share some clinical features including abdominal pain, constipation and diarrhea. Furthermore, some patients with FMF do not have typical abdominal pain and fever attacks rather they have nonspecific symptoms. This makes the diagnosis of FMF harder and lead to a delay in starting the colchicine treatment. Both diseases lack specific diagnostic tests. We aimed to determine the prevalence of IBS in patients with established diagnosis of FMF. Materials and methods: FMF patients who had been diagnosed according to Tel-Hashomer criteria in Rheumatology clinic of a university hospital were included in the study between January 2011 and December 2011. 10 point IBS questionnaire according to Rome III criteria was used to determine the presence of IBS. Patients with recent FMF attack and abdominal pain from other reasons were excluded. Results: One-hundred and thirteen patients (67 females and 46 males) with an established diagnosis of FMF were included in the study. The mean duration of FMF was 6.4 +/- 6.7 years. IBS prevalence based on Roma III criteria was 40.7% (n=46). IBS prevalence was 30.4% (n=14) in male patients and 47.8 % (n=32) in female patients (p=0.06). In female patients IBS subtypes were as follows; IBS mixed type (IBS-M) 37% (n=12), IBS diarrhea predominant (IBS-D) 22% (n=7), IBS unsubtyped (MS-U) 22% (n=7), and IBS constipation predominant (IBS-C) 19% (n=6), whereas in male patients, IBS-M 57% (n=8), IBS-C 29% (n=4), IBS-D 7% (n=1) and IBS-U 7% (n=1). The most common subtype of IBS was IBS-M in both sexes. Conclusion: IBS is frequent in FMF patients when Rome HI criteria are used for diagnosis. The question to be answered is whether increased frequency or merely the failure of Rome III criteria to differentiate IBS in such patient groups with abdominal discomfort.Öğe Liver abscess after implantation of dental prosthesis(Baishideng Publishing Group Inc, 2012) Gungor, Gokhan; Biyik, Murat; Polat, Hakki; Ciray, Hilal; Ozbek, Orhan; Demir, AliPyogenic liver abscesses are rare but a life-threatening important condition. Dental procedures constitute only rare cases of pyogenic liver abscesses, with only a few cases in the literature. We report a patient with liver abscess following a dental procedure. A 74 years old diabetic male patient was admitted to our hospital with complaints of fatigue, 40 degrees C fever, rigors and right upper quadrant pain, 3-4 d after a dental procedure. Physical examination revealed fever and tenderness in the right upper quadrant. Laboratory examination revealed leucocytosis, elevated erythrocyte sedimentation rate and C-reactive protein and moderately elevated transaminases. An abscess was detected in radiological examination in the medial part of the left lobe of liver, neighboring the gall bladder. He was successfully treated with percutaneous abscess drainage and antibiotherapy. (C) 2012 Baishideng.

Hepatocarcinogenesis is a multiple-phases process, which involves changes in cellular genomes including high cell proliferation.In this study, we aimed to evaluate the relationship of NGAL level at the time of diagnosis with mortality in patients diagnosed with HCC. Material and Methods A total of 35 patients who developed HCC on the ground of HBV(+) and 30 healthy subjects were included in the study. Barcelona Clinic Liver Cancer (BCLC), Okuda staging system, and Milan criteria were used for staging of the patients with HCC. Results The mean age of all patients was 59.54 +/- 11.57 years. Seventeen (48.6%) HCC patients died during 1-year follow-up. Survival of the patients who met the Milan criteria was longer (log-rank (Mantel-Cox) test, chi 2 = 5.353,p= 0.021). Kaplan-Meier curve was drawn for NGAL cut-off value, mortality was found to be higher in patients with a NGAL level higher than 217.50 (log-rank (Mantel-Cox) test, chi 2 = 15.540,p< 0.001). Conclusion In this study, we found that high levels of NGAL at the time of diagnosis were associated with poor prognosis in HCC patients.Öğe Neutrophil gelatinase-associated lipocalin in prediction of mortality in patients with hepatorenal syndrome: a prospective observational study(Wiley, 2014) Gungor, Gokhan; Ataseven, Huseyin; Demir, Ali; Solak, Yalcin; Gaipov, Abduzhappar; Biyik, Murat; Ozturk, BahadirBackground & AimsHepatorenal syndrome (HRS) is a severe complication of cirrhosis which is characterized by renal dysfunction and associated with poor survival. Neutrophil gelatinase-associated lipocalin (NGAL) is a troponin-like biomarker for human acute kidney injury. We aimed to investigate levels of plasma and urine NGAL in HRS and predictive ability of these markers for all-cause mortality, in HRS, stable cirrhosis and control subjects. MethodsA total of 64 patients with cirrhosis (8 patients with type 1 HRS, 22 with type 2 HRS, and 34 without HRS) and 23 control subjects were included in the study. Blood and urine samples were measured with Human NGAL sandwich ELISA. Patients were followed up prospectively. ResultsPatients with type 1 and type 2 HRS had significantly higher plasma and urine NGAL levels compared with stable cirrhosis and control subjects. Cox regression analysis showed that plasma NGAL and MELD-Na scores were independent predictors of mortality. ROC-curve analysis showed that the plot of the plasma NGAL, urine NGAL, MELD-Na and Child-Turcot-Pugh score could predict all-cause mortality in cirrhotic patients' area under the curve (AUC 0.819, 0.686, 0.807 and 0.795 respectively). ConclusionsNGAL could predict mortality in patients with HRS independent of other commonly used risk factors.Öğe Non-Invasive Evaluation of Liver Fibrosis Using Real-Time Elastography and Comparison of Intercostal and Subcostal Approaches(Modestum Ltd, 2015) Uslu, Abdulaziz; Batur, Abdussamet; Biyik, Murat; Acikgozoglu, SaimIn patients with chronic liver diseases, the identification of significant fibrosis is of special interest, because the presence of fibrosis is an important parameter for the estimation prognosis, for survelliance and for treatment decisions in patients with Chronic Liver Diseases. Although percutaneous liver biopsy is the gold standart method for assessing liver fibrosis, it has some limitations including its invasive nature, inconvenience, sampling errors, inadequate specimen size and interobserver variability in pathology interpretation. Therefore many studies have focused on the evaluation of noninvasive methods for the assessment of liver fibrosis stage. One of these methods is real time elastography which measures tissue elasticity. In the present study, we assessed intercostal and subcostal measurement methods to discriminate between normal and fibrotic liver.Öğe A Novel Marker Affecting Survival in Acute Non-variceal Upper Gastrointestinal Bleeding: Cardiac Troponin I(Galenos Publ House, 2021) Dertli, Ramazan; Biyik, Murat; Yolacan, Ramazan; Keskin, Muharrem; Karakarcayildiz, Ahmet; Kayar, Yusuf; Ataseven, HuseyinIntroduction: Acute non-variceal upper gastrointestinal bleeding (ANVUGIB) is an important public health problem with high rates of morbidity and mortality. ANVUGIB results in hypovolemia, hypotension, and shock, increasing cardiac oxygen use and may cause elevated serum levels of cardiac troponin (cTn). In this study, we aimed to evaluate whether elevated cTnI has clinical significance in patients with ANVUGIB. Methods: A total of 62 patients diagnosed with ANVUGIB whose serum cTnI levels were studied at the time of admission and follow-up in our clinic from January 2015 to January 2016 were included in the study. Patients with acute cardiac diseases that may cause elevated cTn were excluded from the study. Results: Forty-three of the patients were male (69.4%), and the mean age of all patients was 71.52 +/- 13.30 years. The mean cTnI level was 0.042 +/- 0.097 in all patients, with cTnI levels higher than the reference value in nine (14.5%) patients. In logistic regression analysis, the factors found to contribute to cTnI were tachycardia, chronic kidney disease, and coronary artery disease. In receiver operating characteristic analysis, cutoff values of 0.025 and 6.5 were found for cTnI and the Rockall score, respectively. In addition, cTnI and the Rockall score were shown to affect survival [log-rank (Mantel-Cox) test: p=0.011; log-rank (Mantel-Cox) test: p=0.014; respectively]. Conclusion: We believe that serum cTnI levels studied during the first admission will be found useful as a biomarker in addition to the other existing risk determination systems, in order to identify patients at risk, even if findings of acute coronary syndrome are not observed in patients presenting with ANVUGIB.Öğe A polypoid mass in the common bile duct(Aves, 2016) Asil, Mehmet; Dertli, Ramazan; Biyik, Murat; Oltulu, Pembe; Ataseven, Huseyin; Polat, Hakki; Demir, Ali[Abstract Not Availabe]Öğe Predictive Ability of Liver Fatty Acid Binding Protein for All Cause Mortality in Patients With Hepatic Encephalopathy: A Prospective Observational Study(Nature Publishing Group, 2017) Cakir, Ozlem Ozer; Toker, Aysun; Ataseven, Huseyin; Demir, Ali; Polat, Hakki; Gungor, Gokhan; Biyik, Murat[Abstract Not Availabe]Öğe Predictive Ability of Liver Fatty Acid Binding Protein for All Cause Mortality in Patients With Hepatic Encephalopathy: A Prospective Observational Study(Nature Publishing Group, 2017) Cakir, Ozlem Ozer; Toker, Aysun; Ataseven, Huseyin; Demir, Ali; Polat, Hakki; Gungor, Gokhan; Biyik, Murat[Abstract Not Availabe]
