Cryptogenic liver cirrhosis and hepatitis E virus (HEV): Are they related?

INTRODUCTION AND OBJECTIVES: Hepatitis E virus (HEV) is one of the most common causes of acute hepatitis. In recent years, its role in the development of chronic hepatitis and cirrhosis especially in immunosuppressed patients and its wide range of extrahepatic involvement have increased the amount of research on HEV. In this study we aimed to investigate the presence of HEV infection in individuals with cryptogenic cirrhosis. MATERIALS AND METHODS: HEV antibodies were analysed using the Anti HEV enzyme-linked immunosorbent assay (ELISA) kit (anti-HEV ELISA; Diapro Prodiagnostic Bioprobes, Milan, Italy). HEV RNA was isolated with using QIAMP Viral RNA mini kit (QIAGEN, Hilden, Germany). The HEV RNA titre was detected with the Rotor Gene 3000 real time polymerase chain reaction (PCR) system using GenoSen's HEV (Rotor Gene) Quantitative Real Time PCR Kit (Genome Diagnostics Private Limited, the Netherlands). RESULTS: Our study included 21 healthy volunteers (12 males) and 35 cryptogenic cirrhosis patients (19 males). The ages of the patients and the controls were similar (46±12.1 vs. 37.5±9.7years). The mean Child-Pugh score was 8±2.5. The anti HEV immunoglobulin G(IgG) positivity rate was 9.5% and 25.7% in the control and patient groups respectively (p>0.05). HEV RNA positivity was not detected in the control group, but 3 cases (8.6%) in the patient group were positive (p>0.05). The HEV RNA, aspartate aminotransferase (AST) and alanine aminotransferase(ALT) levels for these 3 cases were 326.461copies/mL, 91IU/L and 67IU/L; 480copies/mL, 68IU/L and 36IU/L and 72copies/mL, 42IU/L and 24IU/L respectively. There were positive correlations between HEV RNA levels and AST and ALT levels (p<0.05). CONCLUSIONS: Anti HEVIgG and HEV RNA positivity rates are high in cryptogenic cirrhosis although it is not statistically significant and there is a positive correlation between HEV RNA and aminotransferases.

Association of the MEFV gene variations with inflammatory bowel disease in Turkey.

BACKGROUND: Association of NOD2 (CARD15) gene mutations with inflammatory bowel diseases (IBD) is well known. We herein aimed to investigate the role of familial Mediterranean fever-associated MEFV variations in IBD patients as additional regional-specific risk factor. STUDY: One hundred thirty-seven (78 female, 56.9%) IBD patients [62 Crohn's disease (CD), 75 ulcerative colitis (UC)] were enrolled into the study. The diagnosis of all patients was confirmed by colonoscopy, histopathology, and the clinical findings. One hundred one healthy donors' samples were used as healthy controls. All patients were genotyped for the most common E148Q, M608I, M694V, and V726A variations of the MEFV and R702W, G908R, and 1007fs of the NOD2. RESULTS: The overall MEFV variation frequency was found to be higher in the IBD (25.5%) patients (28% in UC, 22.6% in CD) compared with controls (9.9%, P=0.006). This association was stronger with the penetrant exon 10 variations (M694V, M680I, V726A; odds ratio =4.5, P=0.001). Contribution of M694V was higher compared with the other variations (14.5% in CD, 17.3% in UC and 3% in controls, odds ratio =6.039, 95% confidence intervals, 1.7-20.7, P=0.002). The overall frequency of 3 NOD2 variants in the IBD group was not different from that of controls. CONCLUSIONS: The results of this study suggest that the MEFV variations may be an additional susceptibility factor for IBD in certain parts of the world where the carrier rate is high, and the genetic background of the IBD patients may show regional changes.

Anticoagulant therapy and Budd-Chiari syndrome: is it successful?

BACKGROUND/AIMS: Anticoagulant therapy is an accepted treatment for Budd-Chiari syndrome (BCS). However, the natural course of untreated patients is unclear. We aimed to evaluate the efficacy of anticoagulant therapy on survival in BCS. METHODOLOGY: Between 1995 and 2007, 45 patients diagnosed with BCS based on the clinical, biochemical, radiological and histological findings were retrospectively evaluated with respect to underlying disease, therapeutic interventions, complications and overall outcome. Complications and survival during the follow-up period were compared in between anticoagulant treated and untreated cases. RESULTS: Mean patient age was 34.4 +/- 11.8 years and 46.7% (21) of them were male. Median followup time was 24 months (6-132); 8.9% of patients were diagnosed as acute, 31.1% as subacute and 60% as chronic BCS according to disease duration. Centrilobular necrosis was found in 16 of 36 biopsy performed patients. Etiological factors were detected in 60% of patients and 40% of them were cryptogenic. Twenty four of them received anticoagulant therapy, the remaining 21 were followed-up with supportive medical therapy. Five patients who had shunt operation were excluded for survival analyses. Complications were similar between treated and untreated cases (p>0.05). There was a positive correlation between survival and centrilobular necrosis (r=0.376, p=0.037). The mean survival periods were 95.5 months (%95 CI 73-117 months) and 72.5 months (%95 CI 42-103 months) in anticoagulant treated and untreated patients, respectively (p>0.246). CONCLUSION: Most patients with BCS are admitted to hospital at the chronic stage and more than half of them have underlying thrombotic risk factor. In our study, no beneficial effects of anticoagulant therapy were observed on the survival and complications of liver disease.

Effect of proton pump inhibitor (PPI) treatment in obstructive sleep apnea syndrome: an esophageal impedance-pHmetry study.

BACKGROUND/AIMS: There is an increasing interest for a link between gastroesophageal reflux (GER) and obstructive sleep apnea syndrome (OSAS). There is no study in the literature which examines the relationship between OSAS and esophageal functions in adults with impedance. We first evaluated the role of reflux in OSAS with simultaneous polysomnography and impedance-pHmetry and then investigated whether the effect of proton pump inhibitor (PPI) treatment changes in these parameters. METHODOLOGY: Twenty two OSAS patients who had applied to sleep laboratory between September 2007 and May 2008 were consecutively enrolled to the study. Twenty four hours esophageal impedance study was performed during polysomnographic recording. At least 50% of all apneas in patients must proceed with a reflux event in 2 minute intervals in order to be considered reflux related apnea patient. RESULTS: Pathologic reflux episodes were determined in 20 patients (8 were weakly acidic, 12 were acidic). Reflux dependent apnea was found in 6 patients. There was endoscopically esophagitis in all reflux related apnea patients. There was a negative correlation between initial mean SaO2 and gas reflux events at night (p=0.004, r =-0.588) and mixed reflux events at night (p=0.02, r=0.493). There was a statistically significant regression of AHI (apnea hypopnea index) after 3-months PPI treatment (p=0.012). CONCLUSIONS: Reflux may trigger apnea in some of the OSAS patients. Therefore, each OSAS patient must be inquired about esophageal and extraesophageal symptoms of reflux.

Is portal hypertensive enteropathy an important additional cause of blood loss in portal hypertensive patients?

OBJECTIVE: Recently, mucosal changes of small bowel were defined by developing new imaging techniques including capsule endoscopy (CE) in portal hypertensive patients. However, the clinical impact of these changes is unknown. In this study, we aimed to determine the additional cause of blood loss in portal hypertensive patients. MATERIAL AND METHODS: A total of 444 portal hypertensive patients, hospitalized in our clinic between 2005 and 2007, were evaluated. Patients with obscure bleeding were enrolled to this prospective case-control study. CE was performed in 21 patients who met inclusion criteria. Gastroscopy, colonoscopy and computerized tomography/small bowel enema were performed in all patients. RESULTS: Fourteen cirrhotic and seven noncirrhotic portal hypertensive patients were enrolled to this study. Mean age of patients was 47.9±15.6 years, and 13 of 21 were male. Small bowel varices were found in 7 patients (1 active bleeding) and other mucosal abnormalities in 10 patients (vascular ectasia, erosion and edema, 1 active bleeding). Although two of them were normal, jejunal malignant mass was found in two patients (1 active bleeding). Of 21 patients, 19 (90.5%) patients had portal hypertensive abnormalities (including varices). However, ileal varices rate was 57.1% (4 patients) in noncirrhotic portal hypertensive patients and 21.4% (3 patients) in cirrhotics. CONCLUSION: Ninety percent of patients had portal hypertensive abnormalities in small bowel and one-third of them had small bowel varices. Small bowel varices and vascular ectasia were the main causes of obscure bleeding in portal hypertensive patients.

Electron microscopic findings in non-alcoholic fatty liver disease: is there a difference between hepatosteatosis and steatohepatitis?

BACKGROUND AND AIMS: Non-alcoholic fatty liver disease has long been accepted as benign; however, recent evidence suggests that the disease may progress to cirrhosis and hepatocellular carcinoma, although the natural course of the disease is still unclear. This study was designed to comparatively evaluate electron microscopic features of non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH). METHODS: Quantitative and semi-quantitative ultrastructural evaluations were performed on liver biopsies from 23 patients, 10 with NAFL and 13 with NASH. RESULTS: No statistically significant difference was noted between NAFL and NASH patients in ultrastructural features of hepatocytes including megamitochondria, intramitochondrial crystalline inclusions, mitochondrial matrix granules, foamy cytoplasmic appearance, electron-lucent and glycogen-containing nuclear regions, lipofuscin granules, or an increased frequency of vesicles containing electron-dense material in peribiliary Golgi zone; however, the mitochondrial diameter was significantly higher in the NASH patients. Intercellular distance and microvilli between hepatocytes, collagen and electron-dense material accumulation in the space of Disse, electron-dense material accumulation and microvillus density in bile canaliculi did not differ significantly between the groups. CONCLUSIONS: Our data show that, although NAFL and NASH can be distinguished by their distinct light microscopic features, ultrastructural characteristics are similar, which suggests that NAFL may also have the potential to progress to fibrosis and cirrhosis like NASH.

Decreased prohepcidin levels in patients with HBV-related liver disease: relation with ferritin levels.

BACKGROUND: Levels of prohepcidin, a homeostatic regulator of iron absorption, are altered in chronic hepatitis C and liver cirrhosis. However, data on the potential alterations of prohepcidin in patients with HBV-related liver disease are scarce. We investigated whether serum prohepcidin is related to iron overload and perenchymal dysfuction in HBV-related liver disease. METHODS: Three groups of subjects were studied: 66 patients with chronic hepatitis B, 32 patients with HBV-related cirrhosis, and 42 healthy controls without evidence of liver disease. Serum levels of prohepcidin were determined by enzyme-linked immunosorbent assay. RESULTS: Serum prohepcidin levels were significantly lower in patients with HBV-related cirrhosis (175.85 ± 71.5 ng/ml) than in patients with chronic hepatitis B (209.02 ± 62.7 ng/ml P < 0.05) and controls (222.4 ± 128.4 ng/ml, P < 0.05). After adjustment for potential confounders, prohepcidin was found to be an independent predictor of ferritin levels in multiple linear regression analysis (ß = -1.10, t = -3.11, P < 0.01). CONCLUSION: These results demonstrate that prohepcidin levels are reduced in patients with HBV-related cirrhosis and are an independent correlate of serum ferritin.

Are acquired hepatocerebral degeneration and hepatic myelopathy reversible?

BACKGROUND: Acquired hepatocerebral degeneration (AHD) and hepatic myelopathy (HM) are rare complications of chronic liver disease and are usually resistant to medical therapy. MATERIALS AND METHODS: The clinical and laboratory findings of 14 male and 2 female patients with AHD or HM were evaluated. RESULTS: The prevalence of AHD and HM was 2% inpatient case series in the last 10 years. The median age of the patients (5 Child's B and 11 Child's C) was 48.7 years (28 to 66 y), and the mean known duration of the liver disease was 75 months (24 to 194 mo). The median time of onset of neurologic findings after diagnosis of the liver disease was 14.5 months. Eight patients who had marked spastic paraparesis or tetraparesis were included in the HM group and all others had AHD group. Sixty-nine percent of the patients had a spontaneous or surgical portosystemic shunts, and the remaining dense retroperitoneal collaterals. During the follow-up period of median 29 months (4 to 72 mo), 12 patients died while waiting for liver transplantation, and these patients suffered from the several complications of chronic liver disease more than the living patients. A marked improvement was observed in 2 of the patients (1 with AHD and the other with HM) at 6 and 8 months after the liver transplantation, respectively. CONCLUSIONS: Our data suggest that liver transplantation had an important effect on the improvement in these patients.

Intestinal metaplasia in portal hypertensive gastropathy: a frequent pathology.

OBJECTIVE: To compare the frequency of intestinal metaplasia (IM) in patients with portal hypertensive gastropathy (PHG) to the control group with functional dyspepsia. METHODS: Two-hundred and eighty-nine cases were prospectively evaluated in three groups (controls:group I--123 patients; cirrhotics: group II--135 patients; noncirrhotic portal hypertensives: group III--31 patients). Mucosal biopsies (three antrum, one angulus, two corpus) were taken and examined for atrophy, IM, dysplasia, Helicobacter pylori (Hp) and histologic PHG. RESULTS: Frequencies of IM in groups I, II and III were 17.1% (type I, 3.3%; type II, 10.6%; type III, 3.3%), 34.3% (type I, 9.6%; type II, 17%; type III, 6.7%) and 33.3% (type I, 9.7%; type II, 12.9%; type III, 9.7%), respectively. In patients with PHG, frequency of IM was significantly higher than in control group (P<0.05) and correlated with the severity of PHG (P<0.05). The frequency of type III IM was not statistically different among the three groups. Frequency of atrophy in cirrhotic patients was higher than in control group (17.9% in group I, 32.6% in group II, 25.8% in group III; P<0.05). In the control group, Hp prevalence was significantly higher than in patients with PHG (P<0.05) and there was a positive correlation between Hp and atrophy (P<0.05). In multivariate analysis, PHG and age were found as independent predictors for IM; PHG, age and Hp for atrophy. CONCLUSION: Frequencies of atrophy and IM are higher in patients with PHG. PHG is a reliable marker for IM and atrophy in gastric mucosa.

What is the reason of elevated alanine aminotransferase level in HBeAg negative patients with low viremia: NAFLD or chronic hepatitis?

BACKGROUND AND STUDY AIMS: Increased alanine aminotransferase (ALT) levels with negative hepatitis B virus (HBV) DNA by hybridization is a common problem in Turkey where is a mild endemic region. We aimed to evaluate the causes of elevated ALT levels in patients who are negative for hepatitis B e antigen (HBeAg) and HBV DNA (by hybridization) for at least 6 months. PATIENTS-METHODS: Forty-nine patients were enrolled in this study. Histological changes [histological activity index (HAI), and the extent of fibrosis] were assessed according to the Knodell scoring system and steatosis were graded by Brunt's classification for NAFLD in all patients. RESULTS: A mean age of the patients was 34.9 +/- 12.1 years (16-70). 43 (87.8%) of them were male. Mean ALT level was 95 +/- 39.7 IU/L (50- 258). Hyperglycemia (>100 mg/dL) and hyperlipidemia were found in 12 and 24 patients, respectively. Hepatic steatosis (7 patients grade 1; 5 patients grade 2; and 7 patients grade 3), ground-glass hepatocyte, chronic hepatitis, and Wilson disease were found in liver biopsy in 38.8%, 32.6%, 26.6%, 2%, respectively. Mean HAI was 6.5 +/- 3.6 (4-12) in chronic hepatitis. Seven patients (53.9%) were in stage 1 and 2 while 6 patients (46.1%) were in stage 3 and 4. CONCLUSIONS: Nonalcoholic fatty liver disease is the most common cause of elevated ALT levels in HBeAg negative/HBV DNA negative patients. Chronic hepatitis B was found in 26.6% of these patients.

Pneumatic balloon dilatation in primary achalasia: the long-term follow-up results.

BACKGROUND/AIMS: Pneumatic dilatation is a safe and most effective treatment for achalasia. We analyzed the long-term results of pneumatic dilatation in primary achalasia by objective and subjective findings. METHODOLOGY: Pneumatic dilatation was performed in patients that were diagnosed with primary achalasia in our manometry laboratory between 1993-1999 years. We evaluated patients with clinical, radiologic, endoscopic and manometric results before treatment. Mean esophageal diameters on the level of the lower esophageal sphincter and middle esophagus were measured by barium esophagograms. The patients were clinically reevaluated after one week and barium esophagograms were repeated one month later after dilatation. Clinical examination, endoscopy and manometry were done at 1, 3, 6 and 12 months and repeated yearly for follow-up period. A statistical comparison of pre- and posttreatment on the frequency of dysphagia, radiological diameter of the esophagus and manometric data was performed using unpaired t tests and chi2 tests. RESULTS: Pneumatic dilatation was performed on 50 adult patients with a mean age 41.42+/-18.07 years. A single dilatation was successful in forty patients (80%) and two to three dilatations were performed in ten (20%) patients. The median number of dilatations was 1.26. In the postdilatation period, mean short-term (< 1 year) and long-term (2-7 years) clinical improvement was 82.8% and 66.85% respectively. The mean diameter of the esophagus was regressed to 26.51+/-7.69 mm from 36.66+/-11.23 mm (p<0.001) and the mean diameter of the lower esophageal sphincter was increased to 8.38+/-3.12 mm from 2.58+/-1.13 mm (p<0.001) with pneumatic dilatation. The mean pretreatment pressure of lower esophageal sphincter was 41.14+/-11.34 mmHg and these values were 18.79+/-7.85 mmHg (p<0.001), 13.18+/-9.53 mmHg (p<0.001) in the 1st, and 5th years of the posttreatment period, respectively. The mean pressure of the lower esophageal sphincter was 31.78+/-8.91 mmHg in nonresponder patients during the posttreatment period; there was no significant difference prior to pneumatic dilatation (p>0.1). Surgical operation was performed on 5 patients (10%), who had no benefit from pneumatic dilatation. CONCLUSIONS: Pneumatic dilatation is an effective procedure in the treatment of primary achalasia during the short- and long-term period. Treatment evaluation can possibly be made objectively with radiographic and manometric alterations of esophagus that occurred after pneumatic dilatation.

Ulcerative colitis: analyses of 116 cases (do extraintestinal manifestations effect the time to catch remission?).

BACKGROUND/AIMS: Evaluation of clinical, demographic and epidemiologic features of ulcerative colitis and therapy response of these patients. METHODOLOGY: Retrospectively, 116 patients (64.7% female) were enrolled in this study. Mean age and mean follow-up period were 36+/-16, 5+/-2 years, respectively. RESULTS: The most common anatomic involvement was pancolitis (60.3%) and the others were as follows: left side 25%, rectum 13.8% and ileum (backwash ileitis) 0.9%. Extraintestinal manifestations were observed in 42.2% of patients (sacroiliitis 12%, primary sclerosing cholangitis 7.6%, pyoderma gangrenosum 2.4%, peripheral arthropathy 1.6%, autoimmune hepatitis 1.6%, steatosis 12.9%, gallstone 0.8%, perianal fistulas 0.8%, sagittal sinus thrombosis 0.8%, psoriasis 0.8%). Multiple extraintestinal manifestations were observed (primary sclerosing cholangitis + pyoderma gangrenosum) in 2 patients. Colonic perforation due to toxic megacolon was observed in only one patient during follow-up period. The mean period for remission was 3.7 months in 72% of patients with pancolitis by the treatment of 5-aminosalicylic acid (5-ASA) (2-3 gr/day) + methylprednisolone (1 mg/kg/day) +/- (for maintenance of remission) azathioprine (AZT) (1.5-2 mg/kg/day); 3.7 months in 72% of left-sided colitis by 5-ASA +/- corticosteroid enemas +/- methylprednisolone (1 mg/kg/day) +/- (for maintenance of remission) AZT (1.5-2 mg/kg/day) and 3.7 months in 62.5% of patients with distal colitis by 5-ASA (p.o. +/- enema) +/- corticosteroid enemas. Colectomy was performed on 7 patients refractory to these treatments. Six patients (4 of them had pancolitis) were treated with cyclosporine (Cys) (4 mg/kg/day, p.o.). Only one patient, a non-responder to Cys therapy, had colectomy. The mean remission time was 4.7 months in 80.6% of patients with extraintestinal involvement and 3.2 months in 71.2% of patients without extraintestinal involvement (P=0.002). CONCLUSIONS: Medical therapy was generally enough for the treatment. Cys and/or surgery can be another choice for the patients that do not respond to the medical therapy. Extraintestinal manifestations do not change the remission rate, but prolong the time to catch remission.

Cyclosporin for severe ulcerative colitis attacks.

BACKGROUND/AIMS: Cyclosporin-A is used as alternative medical therapy in steroid refractory ulcerative colitis with severe activity. In spite of known effectivity, the long term results of cyclosporin-A therapy is not clear for today. METHODS: The results of 13 steroid refractory patients that treated with cyclosporin-A were retrospectively assessed. Cyclosporin-A was started as orally, 8 mg/kg/day in 4 patients and intravenously, 4 mg/kg/day in 9 patients. Intravenous therapy changed to oral therapy one week after beginning. Patients also received 5-ASA and azathioprine. Steroid was tapered. RESULTS: Ten patients responded to treatment in a mean of 9 days (range: 2-30 days). Three unresponded patients underwent total colectomy on 7, 11 and 19th day of therapy. Ten initially responded patients received the drug for average 4.9 months. Of these, four relapsed during and one relapsed soon after therapy. Four of 5 relapser patients underwent colectomy. One patient that not accepted surgical intervention is still receiving medical therapy. Remaining 5 patients, 38% of total group; 50% of patients that initially responded, maintain the remission at the end of average 17 months of follow up period. CONCLUSION: Cyclosporin-A therapy in severe ulcerative colitis that is refractory to steroids, provides initial remission in 80% of patients and allows 40% to retain their colon for 1 year.

Terlipressin and albumin combination treatment in hepatorenal syndrome.

OBJECTIVES: Hepatorenal syndrome (HRS) is a severe complication of cirrhosis, leading to death in nearly all of cases in the absence of liver transplantation. Several treatments have been attempted as a bridge to liver transplantation. Promising results have been shown with terlipressin and albumin treatment. The aim of this retrospective study was to evaluate our patients with HRS and the effects of combined therapy of terlipressin and albumin on survival. PATIENTS AND METHODS: Twenty two patients (15 with type 1 HRS and 7 with type 2 HRS) who were admitted to our clinic between 1996 and 2001, were enrolled. All 7 pts with type 1 HRS were given terlipressin 2-4 mg/day and albumin 2 x 20 g/day for 6 days (range: 3-14). RESULTS: Rate of mortality in hospital was 64% in total group, 80% in type 1 and 29% in type 2. Additionally rate of death was 57% in type 1 patients that received terlipressin+albumin and 100% in unreceived ones (p<0.05). CONCLUSION: In this retrospective study, survival following improvement in renal function was noted in nearly half (43%) of type 1 patients that received terlipressin+albumin. Parameters associated with response to terlipressin+albumin and increased survival should be defined better in a large cohort of cirrhotic patients with HRS.

Intestinal metaplasia of the gastric cardia: a study from Turkey.

BACKGROUND/AIMS: We aimed to investigate the prevalence of intestinal metaplasia in the cardia of a patient group with high incidence of Helicobacter pylori infection presenting for elective upper endoscopy. We also re-evaluated the relation between intestinal metaplasia in the cardia and gastroesophageal reflux disease, smoking, alcohol history, H. pylori infection, Barrett's esophagus and intestinal metaplasia elsewhere in the stomach. METHODOLOGY: Sixty patients presenting for elective upper endoscopy were included in this study. Prior to undergoing endoscopy each patient was questioned with regard to the clinical indication and symptoms including heartburn, regurgitation, and dysphagia. In addition, a smoking and alcohol history were recorded. Endoscopic biopsies: 1) one from the midantrum on the lesser curvature, 2) one from the incisura angularis, 3) one from the mid-corpus on the lesser curvature, 4) one from the columnar side of the squamocolumnar junction, 5) one from the squamous side of the squamocolumnar junction, 6) one from 2 cm distal to the esophagogastric junction, 7) one from across the squamocolumnar junction. Slides were stained using a combination of hematoxylin-eosin with Alcian blue at pH 2.5 for intestinal metaplasia. Each specimen was examined for the presence of H. pylori. RESULTS: The prevalence of H. pylori infection was 63%. Prevalence of the H. pylori infection was significantly lower in the patients with intestinal metaplasia of the cardia than in the patients without intestinal metaplasia of the cardia (P = 0.025). There was a positive correlation between the age of the patients and having intestinal metaplasia of the cardia (r = 0.286, P = 0.008). There was no relationship between intestinal metaplasia of the cardia and pyrozis, regurgitation, dysphagia, history of alcohol and smoking esophagitis determined by endoscopy or histopathology, sex, intestinal metaplasia elsewhere in the stomach (P > 0.05). CONCLUSIONS: The incidence of the intestinal metaplasia of the gastric cardia in Turkey is less than that of western countries. Intestinal metaplasia of the gastric cardia negatively correlates with H. pylori infection. And there was no relationship between gastric cardia intestinal metaplasia and reflux disease. Further investigations are needed for determining the premalign lesion and etiologic factors for cancer of the gastric cardia.

Liver abscess as a rare complication of Crohn's disease: a case report.

Pyogenic liver abscess is a rarely seen extraintestinal complication of Crohn's disease. It has different features from other liver abscesses. Its clinical and laboratory findings are not specific and mimic the reactivation of Crohn's disease and diagnosis can be delayed. The radiological methods are very useful in diagnosis and treatment of liver abscess. In this paper, we present a patient with pyogenic liver abscess which developed in the course of Crohn's disease.

Efficacy of cyclosporin in severe ulcerative colitis attack.

BACKGROUND/AIMS: Cyclosporin-A is used as a alternative medical therapy in steroid resistant ulcerative colitis with severe activity. In spite of its known efficacy, the long term effects of are not entirely clear. METHODS: The records of 13 steroid resistant patients treated with cyclosporin-A were retrospectively assessed. Cyclosporin-A had been prescribed orally at a dose of 8 mg/kg/day in four patients and intravenously, 4mg/kg/day in nine patients. Intravenous therapy was changed to oral therapy after one week and patients also received 5-ASA and azathioprine. Steroid treatment was tapered. RESULTS: Ten patients responded to treatment in a mean of nine days (range: 2-30 days). Three patients who did not respond underwent total colectomy on day seven, 11 and 19 of therapy. The 10 patients who initially responded received the drug for an average of 4.9 months; four of these relapsed during and one relapsed soon after discontinuation of therapy. Four of the five patients who relapsed underwent colectomy and the one patient who did not accept surgical intervention continued medical therapy. The remaining five patients (38% of the total group; 50% of the patients who initially responded) remained in remission at the end of an average 17 month follow up period. CONCLUSIONS: Cyclosporin-A therapy in severe ulcerative colitis that is resistant to steroids, provides initial remission in 80% of patients and allows 40% to retain their colon for one year.

Alverine induced toxic hepatitis: a case report.

Drug-induced hepatotoxicity is an important cause of hepatocellular injury. Hepatic necrosis may range from asymptomatic elevations in transaminases to fulminant hepatic failure and death. Alverine is an antispasmodic drug which is especially used in patients with irritable bowel syndrome. Only a few cases of alverine associated hepatotoxicity have been reported previously. We present the case of a patient with alverine induced hepatotoxicity and cholestasis, which has only seldomly been reported in the literature.

Foreign material in the gastrointestinal tract: cocaine packets.

Smuggling drugs by swallowing or inserting into a body cavity is not only a serious and growing international crime, but can also lead to lethal medical complications. The most common cause of death in 'body packers', people transporting drugs by ingesting a packet into the gastrointestinal tract, is acute drug toxicity from a ruptured packet. However, more than 30 years after the initial report of body packing, there is still no definitive treatment protocol for the management of this patient group. The treatment strategy is determined according to the particular condition of the patient and the clinical experience of the treatment center. Surgical intervention is also less common now, due to both the use of improved packaging materials among smugglers and a shift towards a more conservative medical approach. Herein, we report a case of toxicity from ingested packets of cocaine that leaked and, despite surgery, resulted in exitus of the patient.

Isolated hepatic tuberculosis: a rare cause of hepatic mass lesions.

Hepatic tuberculosis usually accompanies pulmonary and extrapulmonary tuberculosis. Although isolated hepatic tuberculosis is a very rare condition, it should be considered in the differential diagnosis of a hepatic mass. Here, we report a 42-year-old woman presenting with weight loss, fever, night sweats, and a hepatic mass on the abdominal ultrasonography and magnetic resonance imaging (MRI). Ultrasonography-guided percutaneous needle biopsy demonstrated a caseating granuloma with epithelioid histiocytes and giant cells compatible with the diagnosis of tuberculosis. The patient was treated with four anti-tuberculous drugs for 1 year. She recovered clinically, and her post-treatment abdominal MRI was normal.
