RESUMO

BACKGROUND/AIMS: Proton-pump inhibitor and ranitidine bismuth citrate-based triple regimens are the two recommended first line treatments for the eradication of Helicobacter pylori. We aimed to compare the effectiveness and tolerability of these two treatments in a prospective, multicentric, randomized study. MATERIALS AND METHODS: Patients with dyspeptic complaints were recruited from 15 study centers. Presence of Helicobacter pylori was investigated by both histology and rapid urease test. The patients were randomized to either ranitidine bismuth citrate 400 mg bid plus amoxicillin 1 g bid plus clarithromycin 500 mg bid (n=149) or lansoprazole 30 mg bid plus amoxicillin 1 g bid plus clarithromycin 500 mg bid (n=130) treatment arm for 14 days. Adverse events have been recorded during the treatment phase. A 13 C urea breath test was performed 6 weeks after termination of treatment to assess the efficacy of the therapy. Eradication rate was calculated by intention-to-treat and per-protocol analysis. RESULTS: Two hundred seventy-nine patients (123 male, 156 female) were eligible for randomization. In per-protocol analysis (n=247), Helicobacter pylori was eradicated with ranitidine bismuth citrate- and lansoprazole-based regimens in 74,6% and 69,2% of cases, respectively (p>0,05). Intention-to-treat analysis (n=279) revealed that eradication rates were 65,1% and 63,6% in ranitidine bismuth citrate and in lansoprazole-based regimens, respectively (p>0,05). Both regimes were well-tolerated, and no serious adverse event was observed during the study. CONCLUSION: Ranitidine bismuth citrate-based regimen is at least as effective and tolerable as the classical proton-pump inhibitor-based regimen, but none of the therapies could achieve the recommendable eradication rate.

RESUMO

A 55-year-old hemiplegic woman with percutaneous endoscopic gastrostomy (PEG) was referred to our clinic for upper gastrointestinal system bleeding and for a high level of cholestatic enzymes. She had a medical history of cerebra vascular accident three years previously and cholecystectomy one year previously. We performed gastroscopy and saw a retained surgical sponge in the bulbus. After removal of the gossypiboma, endoscopic sclerotherapy was performed for the bleeding area at the bulbus. After the procedure, the upper gastrointestinal bleeding stopped and the high level of cholestatic enzymes returned to normal.

RESUMO

Ghrelin possesses various biological activities -- it stimulates growth hormone (GH) release, plays a major role in energy metabolism, and is one of the hormones that affects body composition. It also plays a role in modulating immune response and inflammatory processes. In this study we aimed to determine whether serum ghrelin levels had correlation with markers associated with disease activation. We also investigated any probable relationship between serum ghrelin level and nutritional status. Serum levels of ghrelin and its relationship with disease activity and nutritional status were evaluated in 34 patients with ulcerative colitis (UC), 25 patients with Crohn's disease (CD), and 30 healthy controls. Serum ghrelin levels, serum IGF-1 and GH levels, and markers of disease activity (sedimentation, C-reactive protein, and fibrinogen) were measured in all subjects. Body composition and nutritional status was assessed by both direct (by anthropometry) and indirect (by bioimpedance) methods. Serum ghrelin levels were significantly higher in patients with active UC and CD than in those in remission (108 +/- 11 pg/ml vs. 71 +/- 13 pg/ml for UC patients, P < 0.001; 110 +/- 10 pg/ml vs. 75 +/- 15 pg/ml for CD patients, P < 0.001). Circulating ghrelin levels in UC and CD patients were positively correlated with sedimentation, fibrinogen and CRP and was negatively correlated with IGF-1, BMI, TSFT, MAC, fat mass (%), and fat free mass (%). This study demonstrates that patients with active IBD have higher serum ghrelin levels than patients in remission and high levels of circulating ghrelin correlate with the severity of disease and the activity markers. Ghrelin levels in inflammatory bowel disease (IBD) patients show an appositive correlation with IGF-1 and bioelectrical impedance analysis, body composition, and anthropometric assessments. Finally, we arrived at the conclusion that ghrelin level may be important in determination of the activity in IBD patients and evaluation of nutritional status.

RESUMO

BACKGROUND: Helicobacter pylori eradication rates have tended to decrease recently possibly related with increasing antibiotic resistance. The present study investigated the efficacy of three different ranitidine bismuth citrate (RBC) based triple regimens in a population with high prevalence of H. pylori. METHODS: 300 consecutive H. pylori positive patients with non-ulcer dyspepsia were randomized into three regimens: (1) RBC 400 mg, amoxicillin 1000 mg and tetracycline 500 mg [RBC-AT], (2) RBC 400 mg, amoxicillin 1000 mg and clarithromycin 500 mg [RBC-AC], (3) RBC 400 mg, metronidazole 500 mg and tetracycline 500 mg [RBC-MT]. Tetracycline was given q.i.d, all other drugs were given b.i.d. for 14 days. Gastroscopy and (14)C-Urea breath test (UBT) were performed before enrollment and UBT only was repeated 6 weeks after the end of treatment. RESULTS: 274 patients completed the protocols. The overall 'intention to treat' and 'per protocol' H. pylori eradication rates in all subjects were 57.6% (95% CI: 52-63) and 63.1% (95% CI: 57-68), respectively. The eradication rates achieved in the groups (RBC-AT, RBC-AC and RBC-MT) were 64.4% (95% CI: 54-74), 66.2% (95% CI: 56-76), and 58.9% (95% CI: 49-68) on 'per protocol' analyses, respectively. There was no difference in eradication rates, compliance and major side effects between the groups. CONCLUSION: The current RBC-based H. pylori eradication therapy is not adequately effective.

RESUMO

We report a 35-year-old male patient with chronic constipation and infertility for 4 years. Spermiogram revealed severe oligospermia. An external mass compressing the rectum was found during rectal examination and flexible rectosigmoidoscopy. Abdominal computed tomography showed a presacral cystic mass which displaced the bladder anteriorly. The cyst was completely removed with open surgery. Histopathologic analysis revealed a cystic lesion covered with squamous epithelium including polymorphonuclear leukocytes, macrophages and sperm cells. After the operation, the patient's symptoms were relieved. We considered that the constipation was caused by external compression by the vesicula seminalis cyst. In cases of constipation with infertility, vesicula seminalis cyst should be kept in mind.

RESUMO

OBJECTIVE: To evaluate the organelle-based changes in acinar cells in experimental acute necrotizing pancreatitis (ANP) after taurine treatment and the association of electron microscopic findings with histopathological changes and oxidative stress markers. METHODS: The study was performed in February 2005 at Gulhane School of Medicine and Hecettepe University, Turkey. Forty-five rats were divided into 3 groups. Acute necrotizing pancreatitis was induced in groups II and III. Groups I and II were treated with saline and Group III with taurine 1000 mg/kg/day, i.p, for 48 hours. Histopathological and ultrastructural examinations were determined using one-way analysis of variance and Kruskal-Wallis tests. RESULTS: Histopathologic findings improved significantly after taurine treatment. Degree of injury in rough and smooth endoplasmic reticulums, Golgi apparatus, mitochondria and nucleus of acinar cells also decreased with taurine in correlation with biochemical and histological results. CONCLUSION: Taurine improves acinar cell organelle structure, and ultrastructural recovery in ANP reflects histological improvement.

RESUMO

BACKGROUND/AIMS: Fibrosis and cirrhosis are common complications of chronic liver diseases. An imbalance between fibrogenesis and fibrolysis results in scarring of the liver parenchyma. We aimed to investigate the possible antifibrotic effectiveness of a newly modified interferon molecule peginterferon alpha2b (PEG-IFNalpha2b) which has better antiviral activity, and ursodeoxycholic acid (UDCA). METHODOLOGY: Liver fibrosis was established on 60 male Sprague Dawley rats with CCl4 in 12 weeks. After cessation of CCl4 Group I was left for spontaneous recovery. Group II was treated with PEG-IFN 1.5 microg/kg/week, Group III with UDCA 25 mg/kg/day and Group IV with combination of both drugs. All rats were killed at week 16. Histopathologic fibrosis scores, tissue hydroxyproline, TIMP-1 and MMP-13 levels were determined. Hepatic stellate cell apoptosis was detected by dual staining with TUNEL technique and anti-alpha smooth muscle actin. RESULTS: Fibrosis scores were lower in Group II, III and IV than Group I (p<0.05 for group I vs. II and III; p<0.01 for group I vs. IV). Tissue hydroxyproline levels were significantly decreased in Group II, III and IV when compared to Group I (p<0.05 for group I vs. II, p<0.01 for group I vs. III and IV). Lower liver TIMP-1 and higher MMP-13 levels were measured in Group II, III, and Group IV than Group I (p<0.01 for TIMP-1 and p<0.01, for MMP). Activated HSC apoptosis was significantly increased in Group II, III and IV when compared to Group I (p<0.01, for all). There was significantly higher apoptosis in Group II than Group III and IV (p<0.01). CONCLUSION: Treatment with both PEG-IFNalpha2b and UDCA improved CCl4 induced rat liver fibrosis. Significantly higher effects were obtained using these agents in combination.

RESUMO

BACKGROUND AND STUDY AIMS: Caustic ingestion caused by swallowing a detergent can produce a progressive and devastating injury in the esophagus and stomach. One of the most important outcomes of the corrosive oesophagitis is the stricture formation, which is resistant to treatment. The aim of this study was firstly to determine the relation between agent, inflammation and stricture, and secondly investigate the efficiency of dilation in patients having esophageal stricture due to corrosive oesophagitis. PATIENTS AND METHODS: In this study, 58 cases with post caustic oesophagitis, which had been admitted to our clinic or emergency department between January 1999 and December 2004, were assessed retrospectively. Dilation of esophageal stricture of the cases was performed by Savary-Gilliard bougies. RESULTS: The most frequently ingested substance was alkaline (48.2%). Concerning all the patients, the most frequent location of caustic injury was upper esophagus (36.2%), and grade I injury was the most frequently encountered one (34.4%). Thirty patients (51.7%) developing stricture were treated by repeated dilations. The most common location of stricture was middle esophagus (50%), and severe stricture was the most common one among all stricture grades (46.7%). Alkaline ingestions yielded more severe stricture than acids. Eight of the patients with stricture (26.6%, 8/30), who didn't respond to periodic esophageal dilation, underwent esophageal resection or bypass surgery. CONCLUSION: Dilation with Savary-Gilliard bougies is a quite effective method for stricture after corrosive oesophagitis.

RESUMO

BACKGROUND: We aimed to investigate the effects of hyperbaric oxygen therapy on bacterial translocation and acinar cell ultrastructure in a rat model of acute necrotizing pancreatitis. METHODS: Forty-eight male Sprague-Dawley rats were randomly divided into three groups. Acute pancreatitis was induced in groups II and III. Groups I and II did not receive any treatment, and group III was treated with hyperbaric oxygen. All surviving animals were killed 48 h after the induction of pancreatitis. Bacterial translocation and histological and ultrastructural changes were determined. RESULTS: The incidence of bacterial translocation in group III was significantly lower in comparison with group II (P<0.001). Histopathological and ultrastructural injury scores were also significantly lower in group III (P<0.001 and P<0.04, respectively). CONCLUSIONS: Hyperbaric oxygen therapy displayed beneficial effects on pancreatic superinfection and or histopathological and ultrastructural changes in experimental necrotizing pancreatitis.

RESUMO

BACKGROUND: Although steatosis is common in patients with severe hyperhomocysteinemia due to deficiency of cystathionine beta-synthase, there are no satisfactory data on homocysteine concentrations in patients with non-alcoholic fatty liver disease. The main aim of the present study was to evaluate the clinical significance of plasma homocysteine concentrations in patients with non-alcoholic fatty liver disease. METHODS: Seventy-one non-alcoholic fatty liver disease patients, 36 patients with chronic viral hepatitis and 30 healthy persons were enrolled in the study. Homocysteine levels were measured by high-performance liquid chromatography. Insulin, folate, vitamin B(12) and lipoprotein levels were also determined in all groups. RESULTS: Homocysteine in the non-alcoholic fatty liver disease group was found to be significantly higher than other groups. Homocysteine was found to be significantly higher in the non-alcoholic steatohepatitis group when compared with simple steatosis group. A positive correlation was found between homocysteine and triglyceride, very-low-density-lipoprotein (VLDL) cholesterol, insulin, and index of insulin resistance in the non-alcoholic fatty liver disease group, and a negative correlation was found between homocysteine and folate, or vitamin B(12) in all groups. The homocysteine threshold for the prediction of steatohepatitis was 11.935 ng/mL. Furthermore; plasma homocysteine was a statistically significant predictor for severity of necroinflammatory activity in non-alcoholic steatohepatitis. CONCLUSIONS: The plasma homocysteine concentrations were significantly higher in patients with non-alcoholic fatty liver disease, while the concentrations were not affected by chronic viral hepatitis. Plasma homocysteine is a parameter for discriminating steatohepatitis from simple steatosis. Determining the plasma homocysteine concentrations may facilitate selection of steatosis patients in whom a liver biopsy should be performed.

RESUMO

BACKGROUND: Since it was described in 1980, percutaneous endoscopic gastrostomy (PEG) has been a widely used method for insertion of a gastrostomy tube in patients who are unable to swallow or maintain adequate nutrition. The aim of the present paper was to determine the complications of PEG insertion and to study pre- and post-procedural nutritional status. METHODS: During the period of March 1999-September 2004, placement of PEG tube was performed in 85 patients (22 women and 63 men). Patient nutritional status was assessed before and after PEG insertion via anthropometric measurements. RESULTS: The most frequent indication for PEG insertion was neurological disorders (65.9%). Thirty patients died due to primary disease and two patients due to PEG-related complications within 5 years. There were 14 early complications in 10 patients (15.2%; <30 days), and 18 late complications in 12 patients (19.6%). Total mortality was 37.6%. All complications other than four were minor. Before PEG insertion, patients were assessed with subjective global assessment and it was determined that 43.2% of them had severe, and 41.9% of them had mild malnutrition. After PEG insertion, significant improvements on patient nutrition levels was observed. CONCLUSION: Percutaneous endoscopic gastrostomy is a minimally invasive gastrostomy method with low morbidity and mortality rates, is easy to follow up and easy to replace when clogged.

RESUMO

A 14-year-old boy was admitted to the hospital with the complaints of epigastric pain and vomiting for three days following epigastric trauma. Physical examination revealed a palpable mass in the epigastrium without any signs of peritoneal irritation. Vital signs, biochemical analysis, chest and abdominal x-rays were normal. Abdominal US, CT and upper gastrointestinal endoscopy showed that there was a well-defined duodenal intramural mass suggesting hematoma. Intraabdominal solid organs were normal and we did not observe free air or extravasation of contrast media. Therefore, we followed up the patient by US. The hematoma completely resolved 48 days after the trauma.

RESUMO

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) procedure is quite difficult to perform in patients with Billroth II anastomosis because of anatomical alterations. The aim of this study is to evaluate retrospectively the results of ERCP applications done in patients with Billroth II operation. METHODOLOGY: Out of the 1632 patients who underwent ERCP between 1992 and 2002, 27 (1.65%) had Billroth II operation. The records of these 27 patients were reviewed. Details noted included indications for ERCP, therapeutic interventions, causes of failure and complications. RESULTS: Out of the patients, 3 were female and 24 male (mean age 62+/-11). 26 patients had extrahepatic biliary obstruction. 1 patient had an external bile drain. The procedure was carried out 1-5 times (mean 1.5+/-1.1). Cannulation was achieved in 17 patients (62.96%). Out of the patients cannulated, 10 had choledocholithiasis, 4 malign choledochal stricture, 1 chronic pancreatitis, 1 bile leak and 1 periampullary tumor. Success rate of endoscopic treatment was 82.35% (14/17). Proximal migration of the stent and hemorrhage in gastric cardia were the complications observed in the distinct patients. CONCLUSIONS: ERCP procedure is quite an effective and safe method for diagnosis and treatment in patients with Billroth II anastomosis and extrahepatic cholestasis in spite of all difficulties.

RESUMO

OBJECTIVES: The aim of the present study was to examine the systemic parameters of oxidative stress and antioxidants in patients with nonalcoholic fatty liver disease and investigate the relationship between these parameters and clinical and biochemical outcomes. METHODS: Fifty-one male patients with nonalcoholic fatty liver disease (group I), 30 age-matched and body mass index (BMI)-matched healthy male subjects, and 30 age-matched male patients with chronic viral hepatitis (group II) were enrolled in the study. RESULTS: Increased systemic levels of malondialdehyde and depletion of antioxidants such as coenzyme Q10, CuZn-superoxide dismutase, and catalase activity were observed in group I. Coenzyme Q10 and CuZn-superoxide dismutase correlated negatively with increasing necroinflammatory activity and fibrosis. Body fat was negatively associated with plasma coenzyme Q10 levels, while an inverse association was found between plasma catalase levels and TG. However, LDL was positively associated with plasma malondialdehyde levels. CuZn-superoxide dismutase levels were negatively associated with glucose, insulin, and HOMA-IR. In addition, the levels of CuZn-superoxide dismutase correlated significantly in a negative manner with BMI. CONCLUSIONS: Our results concerning correlations suggest that disturbances in BMI, body fat, and lipid metabolism may contribute to altered oxidative status in NAFLD, and insulin resistance may be related to decreased antioxidants in NAFLD as well as products of lipid peroxidation. However, although our results suggest interesting correlations, this different mostly "weak" relationships must be taken with caution.

RESUMO

Familial Mediterranean fever (FMF) is a recessively inherited inflammatory disorder, characterized by recurrent attacks of fever and polyserositis. It has been considered that miscellaneous cytokines take part in the pathogenesis of the disease. The aim of this study was to investigate serum levels of soluble interleukin-2 receptor (sIL-2R), interleukin-6 (IL-6), and interleukin-10 (IL-10) in patients with FMF. The study included 42 patients with FMF (3 females, 39 males, mean age: 24.43 years) and 20 healthy volunteers as the control group (18 males, 2 females, mean age: 23.2 years). The patients were chosen according to Eliakim criteria. After recording their history and performing an examination, leukocyte counts, erythrocyte sedimentation rates (ESR), C-reactive protein (CRP), fibrinogen, sIL-2R, IL-6, and IL-10 levels were measured before and during attacks. A significant increase was found in leukocyte ( p<0.001), ESR ( p<0.001), CRP ( p<0.001), and fibrinogen ( p<0.001) levels of the patient group in the attack period compared to those in the quiescent state. sIL-2R ( p=0.019) and IL-6 ( p<0.001) levels showed significant increases during attacks compared to the levels before an attack. There was no significant difference between IL-10 levels. The levels of the three cytokines were significantly high both before and during the attacks compared to the control group. As a result, the elevation of sIL-2R and IL-6 levels both before and during the attacks compared to control group suggests the existence of continuous cytokine activation in the patients. No significant increase in the IL-10 levels in spite of the significant rise of sIL-2R and IL-6 during attacks supports the notion of inflammation and also reveals that compensation by anti-inflammatory IL-10 does not seem to occur.

RESUMO

Arginine has been used by millions of athletes over the past 20 years to enhance production of human growth hormone. The effects of arginine supplementation include increased fat burning and muscle building, enhanced immunity, and improvement in erectile function in men. Excessive doses of basic amino acids such as ethionine, methionine and lysine are known to damage the rat pancreas. Recent studies have demonstrated that excessive doses of arginine induce necrotizing pancreatitis in rats. In this article, we report a 16-year-old male patient hospitalized in our clinic because of severe pain in upper abdomen, nausea and vomiting who was suspected to have arginine-induced acute pancreatitis.

RESUMO

Despite the new diagnostic and therapeutic advancements, acute pancreatitis has still high rate of morbidity and mortality. We aimed to evaluate the effects of hyperbaric oxygen (HBO) therapy alone or combined with S-methylisothiourea (SMT), and meropenem (MER) therapy in an experimental rat model of acute necrotizing pancreatitis. Rats were randomly divided into 8 groups, and acute pancreatitis was induced in all groups except group 1. Treatment protocols were saline for group 2, SMT for group 3, SMT + MER for group 4, SMT + HBO for group 5, HBO for group 6, HBO + MER for group 7, and MER for group 8. All surviving animals were killed 48 hours after the induction of pancreatitis, and specimens were collected. Oxidative stress parameters, histopathologic scores and amylase levels were better in treatment groups than in the positive control group (group 2). The most favorable results were obtained in HBO treatment groups, especially in HBO + MER group (group 7). Our results indicate that adding HBO therapy to the antibiotic therapy will decrease oxidative stress parameters, serum amylase levels, and histopathological score. We suggest that adding the HBO therapy as an adjunctive to the treatment protocol of acute necrotizing pancreatitis may yield improvement in the morbidity and mortality of the disease.

RESUMO

BACKGROUND/AIMS: There are some reports showing that resistance of Helicobacter pylori (H. pylori) to clarithromycin has increased in recent years. We aimed to investigate the current success of a most popular first-line eradication regimen by using two different proton pump inhibitors: lansoprazole and pantoprazole. METHODS: Ninety patients with H. pylori-positive functional dyspepsia were randomized to receive pantoprazole 40 mg b.i.d. or lansoprazole 30 mg b.i.d. in addition to amoxicillin 1,000 mg and clarithromycin 500 mg twice daily for 14 days in a multicenter study. H. pylori infection was determined by histological examination and a rapid urease test. A follow-up endoscopy was performed to assess the H. pylori eradication six weeks after the end of therapy. RESULTS: Seventy-nine patients completed the study protocol properly. The H. pylori eradication rates according to per protocol analysis were 70% in group pantoprazole, amoxicillin and clarithromycin (28/40) and 69.2% in group pantoprazole, amoxicillin and clarithromycin (27/39). The eradication rates according to intention to treat analysis were 62.2% and 60% in lansoprazole, amoxicillin, clarithromycin, pantoprazole, amoxicillin, clarithromycin groups, respectively. The eradication rates were similar in both protocols (p>0.05). CONCLUSIONS: The most popular first-line eradication protocols of H. pylori achieved only a moderate success in the current study. Alternative therapy options are needed instead of clarithromycin-based triple treatment for eradication of H. pylori. The choice of proton pump inhibitor is not important in the eradication rate of H. pylori.

RESUMO

It is well known that there may be an increased tendency for thrombosis in inflammatory bowel disease (IBD). This study presents a case with antiphospholipid antibody syndrome with ulcerative colitis diagnosed during pregnancy. A 30-year-old female patient, in her 6th week of pregnancy, applied to our clinic with complaints of abdominal pain and bloody diarrhea. She had a history of three abortions. She had been given aspirin and heparin treatment due to high levels of anticardiolipin antibody (ACA) in previous examinations that led to the diagnosis of antiphospholipid antibody syndrome. As the left colonoscopic examination of the patient showed ulcerative colitis, aspirin treatment was replaced with mesalazine (750 mg/day, in 3 equal doses). There was a significant relief in complaints of the patient. Medical treatment was interrupted three days before delivery. The patient delivered a baby, at full-term, of 3.6 kg by cesarean section. No adverse effects were observed in the mother or the baby due to the medical treatment. After delivery, mesalazine treatment was restarted. This case is interesting due to the co-diagnosis of IBD in a pregnant woman with antiphospholipid antibody syndrome. Successful and uncomplicated treatment of the patient with mesalazine should also be noted.
