Pentoxifylline attenuates mucosal damage in an experimental model of rat colitis by modulating tissue biomarkers of inflammation, oxidative stress, and fibrosis. Turk J Med Sci 2017; 47:348-356. [PMID: 28263514 DOI: 10.3906/sag-1508-98] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2015] [Accepted: 05/31/2016] [Indexed: 11/03/2022] Open
Abstract
BACKGROUND/AIM This study was designed to identify the effect of pentoxifylline on trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats. MATERIALS AND METHODS Forty-two female Wistar rats were randomly divided into 7 groups: group A, TNBS + intraperitoneal (IP) pentoxifylline; group B, TNBS + IP saline; group C, TNBS + intrarectal (IR) pentoxifylline; group D, TNBS + IR saline; group E, IP pentoxifylline + TNBS; group F, IP saline + TNBS; group G, IR saline. Pentoxifylline was given daily for 3 days before or 6 days after the induction of colitis. Rats were killed after 6 days. RESULTS IP and IR pentoxifylline similarly and significantly reduced damage and histopathological scores. Pentoxifylline attenuated the accumulation of malonyldialdehyde and transforming growth factor β1 and the activities of myeloperoxidase, matrix metalloproteinase-3, and tissue inhibitor of metalloproteinases-1, and it also restored superoxide dismutase activity. The IP route was more effective than the IR route in this regard. Administration of IP pentoxifylline before or after induction did not influence all parameters. Conclusions: Pentoxifylline showed a therapeutic effect in this experimental colitis model. IP administration seemed to be better. This effect may occur as a result of inhibition of oxidative stress and metalloproteinase activity.

Long-term efficacy and safety of lamivudine, entecavir, and tenofovir for treatment of hepatitis B virus-related cirrhosis. Clin Gastroenterol Hepatol 2013; 11:88-94. [PMID: 23063679 DOI: 10.1016/j.cgh.2012.10.003] [Citation(s) in RCA: 62] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2012] [Revised: 09/26/2012] [Accepted: 10/02/2012] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Data are limited on the efficacy and safety of tenofovir and entecavir when given for more than 1 year to patients with hepatitis B-related cirrhosis. We investigated the long-term safety and efficacy of these antiviral drugs in patients with chronic hepatitis B virus (HBV) infection, with compensated or decompensated cirrhosis, and compared results with those from lamivudine. METHODS We performed a retrospective analysis of data from 227 adult patients with chronic HBV infection who were diagnosed with cirrhosis, beginning in 2005, at 18 centers throughout Turkey. There were 104 patients who had decompensated cirrhosis, and 197 patients were treatment naive before. Seventy-two patients received tenofovir (followed up for 21.4 ± 9.7 mo), 77 patients received entecavir (followed up for 24.0 ± 13.3 mo), and 74 patients received lamivudine (followed up for 36.5 ± 24.1 mo). We collected data on patient demographics and baseline characteristics. Laboratory test results, clinical outcomes, and drug-related adverse events were compared among groups. RESULTS Levels of HBV DNA less than 400 copies/mL were achieved in 91.5%, 92.5%, and 77% of patients receiving tenofovir, entecavir, or lamivudine, respectively. Levels of alanine aminotransferase normalized in 86.8%, 92.1%, and 71.8% of patients who received tenofovir, entecavir, and lamivudine, respectively. Child-Turcotte-Pugh scores increased among 8.5% of patients who received tenofovir, 15.6% who received entecavir, and 27.4% who received lamivudine. Frequencies of complications from cirrhosis, including hepatic encephalopathy, variceal bleeding, hepatocellular carcinoma, and mortality, were similar among groups. Lamivudine had to be changed to another drug for 32.4% of the patients. CONCLUSIONS Tenofovir and entecavir are effective and safe for long-term use in patients with compensated or decompensated cirrhosis from HBV infection.

Plasma thrombin-activatable fibrinolysis inhibitor as an indicator of inflammation and disease severity in acute pancreatitis. Clin Res Hepatol Gastroenterol 2012; 36:498-504. [PMID: 22230218 DOI: 10.1016/j.clinre.2011.12.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2011] [Revised: 11/28/2011] [Accepted: 12/05/2011] [Indexed: 02/04/2023]
Abstract
AIM In addition to suppressing fibrinolysis, thrombin activatable fibrinolysis inhibitor (TAFI) was suggested to be involved in inflammation. To date, no study has been published that reports the role of TAFI in acute pancreatitis (AP). Therefore, the objective of the present study was to investigate the role of plasma TAFI as an indicator of inflammation in AP, and its association with disease severity. METHODS Plasma TAFI antigen levels quantitatively determined by using ELISA kits in 21 AP patients at onset and remission and 17 healthy controls. Associations of TAFI with inflammatory markers to determine AP and disease severity were assessed. To predict the severity of AP, modified Glasgow prognostic score (mGPS) and computerized tomography severity index (CTSI) were used for each subject. RESULTS Plasma TAFI levels was higher in AP patients at onset of the disease compared with healthy controls. The disease severity according to mGPS was significantly correlated with TAFI levels. Overall, accuracy of TAFI in determining AP was 83.3% with a sensitivity, specificity, NPV and PPV of 80.9%, 85.7%, 81.8%, and 85% respectively (AUC: 0.915). CONCLUSIONS The present study for the first time demonstrated that TAFI is elevated in AP. The appraisal of TAFI levels in patients with AP in conjunction with other markers of inflammation may provide additional information in estimating AP severity.

Abstract
BACKGROUND AND AIM Macrophage inhibitory cytokine (MIC-1) and tissue polypeptide-specific antigen (TPS) are novel markers for several inflammatory and malignant disorders, and there are no sufficient data about the utility of these antigens as serum tumor markers. We aimed at measuring the serum levels of MIC-1 and TPS in patients with benign and malignant pancreatobiliary diseases and at determining their diagnostic efficacy. PATIENTS AND METHODS Sera collected from patients with pancreatic adenocarcinomas (56 cases), periampullary carcinomas other than pancreatic carcinomas (15 cases), benign pancreatic diseases (31 cases), benign biliary diseases (15 cases) and healthy volunteers (33 cases) were analyzed for MIC-1 and TPS and the results were compared with CA 19-9. RESULTS Serum MIC-1 levels increased more significantly in patients with pancreatic carcinomas than in patients with benign pancreatobiliary diseases and healthy controls (p < 0.05). MIC-1 has a similar sensitivity (81%) but a lower specificity (73 vs. 97%) than CA 19-9 in patients with pancreatic carcinomas. Serum TPS was comparable among patients with malignant and benign pancreatobiliary diseases, and healthy controls. CONCLUSION MIC-1 is a valuable tumor marker for the diagnosis of pancreatic cancer. It has a good correlation with CA 19-9. TPS has no diagnostic importance to differentiate pancreatobiliary diseases. and IAP.

Abstract
OBJECTIVE To investigate the diagnostic value of a terminal ileum biopsy in chronic non-bloody diarrhea with normal endoscopic appearance. METHODS Patients who had a terminal ileum biopsy performed between January 2007 and January 2010 during a colonoscopy despite normal endoscopic appearance were reviewed. They were divided into two groups according to the indication for the colonoscopy: non-bloody diarrhea and non-diarrhea; and their histopathological findings were compared. RESULTS By screening the colonoscopy records, 473 patients were found to have had a terminal ileum biopsy. Of these patients, 178 were excluded for various reasons. Finally, 295 patients were suitable for analysis. The non-bloody diarrhea group consisted of 135 patients, while the remaining 160 patients constituted the non-diarrhea group. A histopathological examination of the terminal ileum biopsy specimens in the non-bloody diarrhea group revealed an abnormal histology in eight patients (5.9%), compared with five patients (3.1%) in the non-diarrhea group. No statistically significant difference was found between the two groups (P=0.26). CONCLUSION Although performing a biopsy of the terminal ileum despite a macroscopically normal appearance may offer some additional benefit to the diagnosis of chronic non-bloody diarrhea, prospective trials are needed for assessing the diagnostic value of a terminal ileum biopsy in patients with chronic diarrhea.

Abstract
BACKGROUND/AIMS Cholangitis is one of the most morbid complications of endoscopic biliary drainage and among the commonest causes of endoscopic retrograde cholangiopancreatography-related death. The aim of this prospective study was to investigate the risk factors for the development of cholangitis after endoscopic retrograde cholangiopancreatography in a tertiary referral center. METHODS The study involved 503 consecutive patients with naive papilla who underwent endoscopic retrograde cholangiopancreatography. We included the cholangitis occurring within 72 hours after endoscopic retrograde cholangiopancreatography for all patients undergoing the procedure. All patients received antibiotic prophylaxis before endoscopic retrograde cholangiopancreatography. Factors including age, gender, presentation, nature of the papilla, therapeutic procedures, and the diagnosis were analyzed to predict post-endoscopic retrograde cholangiopancreatography cholangitis. RESULTS Median age was 61.2 +/- 14.8 years and there were 274 (54.5%) women and 229 (45.5%) men. Seventeen (3.3%) patients (9 F, 8 M) developed cholangitis after endoscopic retrograde cholangiopancreatography. The risk of post-endoscopic retrograde cholangiopancreatography cholangitis development was most probable in patients with hilar cholangiocarcinoma. Post-endoscopic retrograde cholangiopancreatography cholangitis risk was significantly higher in patients with biliary dilatation and biliary stent insertion, and without periampullary diverticula (odds ratio, OR: 4.8, 4.4, 1.2, respectively). Total procedure duration was significantly prolonged and common bile duct diameter was significantly increased in patients who had cholangitis. Five patients (3 F, 2 M; 0.9%) died because of post-endoscopic retrograde cholangiopancreatography complicated sepsis. CONCLUSIONS Increased common bile duct diameter, biliary dilatation, biliary stent insertion, prolonged total procedure time, and hilar cholangiocarcinoma have higher post-endoscopic retrograde cholangiopancreatography cholangitis risk. Moreover, the presence of periampullary diverticula was found to decrease cholangitis risk.

Abstract
BACKGROUND The aim of this study was to evaluate the prevalence and features of the major cutaneous manifestations (erythema nodosum [EN] and pyoderma gangrenosum [PG]) and to determine the associations between cutaneous manifestations and other extraintestinal manifestations in patients with inflammatory bowel disease (IBD). METHODS The mucocutaneous manifestations of patients with IBD were studied between December 2002 and June 2007. All patients underwent a detailed whole body examination by a gastroenterologist and dermatologist. RESULTS In all, 352 patients were included in this study; 34 patients (9.3%) presented with at least 1 major cutaneous manifestation. The prevalence of EN (26 patients) and PG (8 patients) in IBD was 7.4% and 2.3%, respectively. EN was more common in Crohn's disease (16/118) than ulcerative colitis (10/234) (P = 0.002). EN was found to be related to disease activity of the bowel (P = 0.026). The prevalence of arthritis was significantly higher in the IBD patients with EN (11/26) than in IBD patients without EN (53/326) (P = 0.006). Arthritis was more common in IBD patients with PG (7/8) than in IBD patients without PG (57/344) (P = 0.00). IBD patients with PG were significantly more likely to have uveitis (1/8) compared with IBD patients without PG (5/344) (P = 0.017). CONCLUSIONS We found the prevalence of 2 important cutaneous manifestations to be 9.3% in IBD in Turkish patients. EN was found to be more common in Crohn's disease and is associated with an active episode of bowel disease and peripheral arthritis. In addition, PG was connected with uveitis and peripheral arthritis.

Serum angiotensin converting enzyme levels in pancreatic diseases. HEPATO-GASTROENTEROLOGY 2008; 55:1814-1817. [PMID: 19102399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/27/2023]
Abstract
BACKGROUND/AIMS Recently, the existence of a local renin angiotensin system (RAS) in the pancreas has been demonstrated in laboratory animals as well as in human. It has been suggested that RAS and angiotensin converting enzyme (ACE) activity increase in diseases involving pancreas tissue. In the present study, we analyzed the relationship between serum ACE levels and pancreas disorders including acute and chronic pancreatitis, and pancreas adenocancer. METHODOLOGY The study groups comprised 14 cases with acute pancreatitis (male/female: 5/9), 38 chronic pancreatitis patients (male/female: 25/13) and 21 pancreas adenocancer cases (male/female: 11/10). The ACE activity in the sample was determined by comparing the sample reaction rate to that obtained with the ACE calibrator. RESULTS Serum ACE levels were 38.28 +/- 23.67 U/L (10-108), 43.71 +/- 23.58 UL (7-120), 39.14 +/- 19.31 U/L (5-77) and 38.04 +/- 13.69 U/L for patients with acute pancreatitis, chronic pancreatitis, pancreas cancer and healthy controls respectively. Serum ACE levels were not significantly different among all groups (p>0.05). There was no significant difference regarding ACE levels in patients with metastasis and without metastasis. There was no correlation between ACE levels and tumor size. CONCLUSIONS Our results showed that serum ACE levels increased in neither benign nor malignant pancreas diseases. However, serum ACE levels may not reflect the actual RAS activity because non-ACE pathways affecting RAS activity have been described. Further studies analyzing non-ACE pathways contributing to RAS activity in human pancreatic disorders are needed.

Abstract
We describe a 65-year-old man who had liver involvement with Churg-Strauss syndrome. He was admitted to the hospital because of fever, weight loss, dyspnea, abdominal pain, skin lesions and paraesthesias. His past medical history revealed a diagnosis of acalculous cholecystitis that had been made eight months earlier. Microscopic examination of a gall bladder biopsy specimen obtained at that time revealed an increase in extravascular eosinophils. There was evidence of a new bilateral pulmonary disease with bronchoconstriction and a transient infiltrated lesion in the right upper lung. The patient's white cell count was 14 620 per cubic millimetre, with 39% eosinophils (5800 per cubic millimetre) and 39% neutrophils. IgE was 503 g/L (normal range, 0 to 100 g/L). Liver function tests were mildly elevated. Fine needle liver biopsy showed active interface hepatitis. A diagnosis of Churg-Strauss syndrome was made. In this patient the syndrome occurred in a rare association with hepatitis, likely due to immunologic events in the liver. The patient was successfully treated with 60 mg/day of prednisolone monotherapy.

Abstract
BACKGROUND AND AIM Rebleeding has remained the most important determinant of poor prognosis in peptic ulcer bleeding. Gastric acid plays an important role in the pathogenesis of rebleeding. We aimed to compare the efficiency of intermittent and continuous pantoprazole infusion treatment on peptic ulcer rebleeding after endoscopic therapy. MATERIALS AND METHOD In this prospective study, patients with active peptic ulcer bleeding or non-bleeding visible vessel were treated initially with endoscopic therapy. They were randomized to receive intermittent or continuous intravenous pantoprazole treatment. Rebleeding rate, duration of hospital stay, need for total blood transfusion and need for urgent surgery were compared among both groups. RESULTS Rebleeding rate (6.1 vs. 8.3%), duration of hospital stay (4.17 vs. 4.41), need for total blood transfusion (2.18 vs. 2.59) and need for urgent surgery (4.1 vs. 4.2%) were similar in intermittent and continuous pantoprazole infusion therapy groups, respectively. There was no bleeding-related death in either group. CONCLUSION In patients with peptic ulcer bleeding, intermittent and continuous pantoprazole infusion after successful endoscopic therapy have comparable outcomes in reducing rebleeding. Both have similar effects on hospital stay, need for blood transfusion and urgent surgery. Intermittent administration has application and cost advantages over continuous infusion.

Abstract
Hepatoportal sclerosis (HPS) is a clinical disorder of obscure pathogenesis with a variable clinical profile. The aim of the study was to summarize the clinical features of Turkish patients with HPS and to measure the serum levels of interleukin (IL)-6 and interferon (IFN)-gamma to determine the T helper cell profile in the pathogenesis. The study was conducted on 34 HPS patients (17 men, 17 women; mean age at diagnosis, 27+/-10 years) and 15 healthy controls. The clinical features of HPS patients including demographics, clinical history, laboratory, and ultrasonography findings were summarized. Serum IL-6 and IFN-gamma levels were measured by using commercially available enzyme-linked immunosorbent assay kits. Gastrointestinal bleeding was the most common dominant presenting symptom. Majority of the patients had preserved liver function tests. Serum triglyceride levels were decreased in 30%. Abdominal ultrasonography revealed well-demarcated bands of increased echogenicity surrounding the portal vein wall and sudden narrowing of the intrahepatic second-degree portal vein branches in all cases. Spontaneous shunts and/or collaterals were seen in 13 cases (37%). Extrahepatic portal vein thrombosis were seen in 7 (20%) patients after at least 5 years of disease duration. Serum levels of both IL-6 (median, 3.2 pg/mL) and IFN-gamma (median, 7.8 pg/mL) were significantly higher in HPS patients compared with the control group (median, 1 pg/mL). HPS has variable clinical profile in different geographic areas of the world. Both Th1 and 2 cells may have a role in the regulation of immune response and pathogenesis of the disease.

Abstract
BACKGROUND Adenosine deaminase (ADA) is found in most tissues including the pancreas. Its role in inflammation and malignancy has been studied experimentally. To date, serum ADA levels in pancreatic diseases have not been studied before. AIM To assess the levels of ADA in patients with pancreatitis and cancer of the pancreas. METHODOLOGY Serum levels of ADA were investigated in 14 cases with acute pancreatitis (mean age 46 years; male/female 5/9), 38 with chronic pancreatitis (mean age 46 years; male/female 25/13), 21 with cancer of the pancreas (mean age 67 years; male/female 11/10), and 21 healthy controls (mean age 40 years; male/female 11/10). The ADA levels were also compared among patients with pancreatic cancer with regard to tumor size and localization and the presence of metastases. Correlation analysis between ADA and CA 19.9 was also performed. RESULTS Serum ADA levels were 12.66 (9.54-20.72), 12.51 (8.88-26.64), 15.36 (10.20-21.05) and 9.39 (6.58-11.84) U/l in patients with acute pancreatitis, chronic pancreatitis, pancreatic cancer, and healthy controls, respectively. Serum ADA levels were significantly higher in acute and chronic pancreatitis, and pancreatic cancer patients compared to the control group (p < 0.05). Pancreatic cancer patients had significantly higher serum ADA levels when compared with acute and chronic pancreatitis cases (p < 0.05). The serum ADA levels were comparable according to tumor size and location and the presence of metastases. There was a linear correlation between serum ADA and CA 19-9 levels (p = 0.027, r = 0.552). CONCLUSIONS Our data suggest that the ADA enzyme may play a role in inflammatory diseases of the pancreas. Serum ADA levels increase in pancreatic disorders especially in pancreatic cancer. It may be a serum marker for the diagnosis of pancreatic cancer.

Abstract
Autosomal-dominant polycystic kidney disease is an inherited disorder characterized by multiple cysts in kidneys and other organs. A 63-year-old man was evaluated for the etiology of recurrent pancreatitis and chronic renal failure. Multiple cysts of kidneys, liver, and pancreas and pancreas divisum was diagnosed. Pancreatitis should be included in the differential diagnosis of abdominal pain in patients with ADPKD. Pancreas divisum may be a predisposing factor for acute pancreatitis in these patients.

Abstract
Our aim was to analyze patients diagnosed with left-sided portal hypertension prospectively and to document the complications at follow-up. Twenty-four patients with isolated splenic vein thrombosis (diagnosed by ultrasonography or angiography or intraoperatively) and/or isolated fundal varices (diagnosed by endoscopy or endosonography) were involved in this study. Demographics, clinical presentation, diagnostic and therapeutic procedures, and morbidity and mortality were recorded in their follow-up. There were 11 and 13 left-sided portal hypertension cases associated with pancreatic diseases and nonpancreatic disorders, respectively. Chronic abdominal pain and gastrointestinal bleeding were the two most common complaints. All patients except one had isolated esophageal (2 cases) or fundal (21 cases) varices. Thirteen patients had splenomegaly on ultrasonography. On Doppler sonography, the splenic vein could be evaluated in 21 of the 24 patients (9 and 6 had complete and partial occlusion, respectively, and 6 had patent blood flow). Urgent intervention with therapeutic endoscopy and splenectomy was performed for two patients each. Medical therapy was begun for three patients according to the underlying diseases. Three patients underwent elective surgery. Two patients were lost to follow-up after the first visit and the mean follow-up of the remaining 22 patients after diagnosis of left-sided portal hypertension was 20 months. Only one patient (with pancreas cancer) had gastrointestinal bleeding at follow-up. All patients with pancreas and gastric cancer died within 2-12 months. Left-sided portal hypertension has various etiologies. It may be difficult to diagnose this entity both endoscopically and radiologically. Treatment should be directed at the underlying diseases. Recurrent hemorrhage due to left-sided portal hypertension is not usual and the prognosis depends mainly on the underlying etiology.
