RESUMEN
OBJECTIVES: The need for colonoscopy is common among diabetic patients. However, there are no standards per se for bowel preparation in patients with type 2 diabetes. In this study, we evaluated the efficacy, safety, and tolerability of sodium phosphate (NaP), and the quality of bowel cleansing in relation to glycemic control and late complications. METHODS: A total of 50 consecutive type 2 diabetic patients and 50 non-diabetic patients underwent bowel preparation by NaP. Fasting blood glucose, sodium (Na), potassium (K), calcium (Ca), phosphorus (P), magnesium, and creatinine levels were measured on the procedure day. Patients were given a tolerability questionnaire regarding symptoms. RESULTS: With regard to bowel preparation quality, optimal bowel cleansing was achieved in 35 (70%) diabetic and 47 (94%) non-diabetic patients (P = 0.002). Abdominal pain or discomfort during and an hour after the procedure was similar in both groups (P >0.05). The changes in Na, K, Ca, P and creatinine levels after NaP use did not reach statistical significance between the groups (P >0.05). In the diabetic patients, there was a significant correlation between the quality of bowel cleansing and mean age, duration of diabetes mellitus, level of hemoglobin A1c (HbA1c), fasting blood glucose level, and diabetic late complications (P <0.05). CONCLUSION: These data suggest that NaP is safe and tolerable in diabetic patients, but the quality of bowel cleansing is worse than in non-diabetic patients. These observations support the concept that the quality of bowel cleansing in those with type 2 diabetes is closely related to the duration and regulation of the disease and the presence of late complications.

INTRODUCTION: The need for colonoscopy is common among diabetics. In this study, we aimed to evaluate the effect of autonomous neuropathy on bowel preparation in type 2 diabetes mellitus (DM) patients. MATERIALS AND METHODS: The study population consisted of 45 patients with DM and 48 non-diabetic, age- and sex-matched subjects. All colonoscopies were performed 5 h after the last dose of sodium phosphate. Colonoscopists rated the bowel preparation quality during the procedure using the Aronchick scale. All patients underwent a detailed cardiologic examination and 24-h Holter rhythm monitoring. Orthostatic hypotension and impairment in heart rate variability were accepted as indicators of autonomous neuropathy. RESULTS: Gender, age, blood pressure, and heart rates did not differ significantly between groups (p > 0.05). Autonomous neuropathy was detected in 14 (31.1%) patients in the DM group and in two (4.2%) in the control group (p < 0.05). Optimal bowel cleansing was achieved in 93.8% of controls and 73.3% of diabetics; bowel cleansing was suboptimal in 26.7% of diabetics and 6.2% of controls (p < 0.05). Optimal bowel cleansing was achieved in six of 14 (42.8%) diabetic patients with autonomous neuropathy; however, optimal bowel cleansing was achieved in 27 of 31 (87.1%) diabetic patients without autonomous neuropathy (p < 0.05). Although optimal bowel cleansing was more prevalent among control patients than in diabetic patients without autonomous neuropathy, the difference was not significant (87.1% vs 93.8%; p > 0.05). CONCLUSION: These data suggest that optimal bowel cleansing is poorer in diabetics with autonomous neuropathy than in those without autonomous neuropathy and controls.

BACKGROUND/AIMS: The correlation of the risk of malignancy with the sum of the diameters of small colonic polyps is unknown, and data regarding this topic are lacking. In this study, the relationship between the sum of the diameters of the total number of colonic polyps and poor histopathologic characteristics was examined. METHODS: A total of 920 neoplastic colon polyps were evaluated in 480 patients. The "total polyp diameter" (i.e. the sum of all polyp diameters identified during colonoscopy), which was calculated in each patient by adding the diameter of each polyp to a sum, was categorized as "small" (<10mm in diameter) or "large" (> or =10mm in diameter). The polyps were further categorized by histopathologic component as "unfavorable" or "favorable" and were divided into 2 groups: group 1 (those identified as carci noma, carcinoma in situ, villous adenoma, and tubulovillous adenoma with a villous component of more than 25%) and group 2 (mixed adenomatous polyps with various degrees of hyperplastic or inflammatory components and adenomas with a tubular component of more than 75%). RESULTS: Large polyps that had a total diameter greater than or equal to 10mm tended to have poor histopathologic characteristics (p<0.05). Polyps generally tended to localize in the left portion of the colon, and malignant polyps or those at risk for malignancy in particular tended to localize in the left colon (p<0.05). CONCLUSIONS: Polypectomy is recommended for patients in whom the sum of the diameter of all colonic polyps exceeds 10mm.

BACKGROUND/AIMS: We aimed to compare the level of thrombocytopenia in cirrhotic patients with HBV and those with HCV, and to investigate whether the reduced serum level of IL-6 in patients with HCV is responsible for the lower platelet count compared to those with HBV through the effect on serum thrombopoietin level. METHODOLOGY: Fifty-three patients with liver cirrhosis, 28 of who were HBV- seropositive (Group A), 25 of who were HCV- seropositive (Group B) and 15 healthy controls were enrolled in this study. RESULTS: Platelet count in group B [75 (1.5-99) K/microL] were lower than those of group A [140 (62-374) K/microL] (p < 0.001). The median levels of serum thrombopoietin in patients [group A: 31.9 (31-113) pg/mL and group B: 38.0 (31.2-102) pg/mL] and controls [31.3 (31-153) pg/mL] did not show statistically significant difference. The patients compared to controls, had higher serum IL-6 levels [3.6 (2-1150) vs. 2.0 (2-9.9) pg/mL], (p < 0.01), which showed similarity in group A and B patients [3.65 (2-1150) vs. 3.3 (2-45) pg/mL], (p=NS). Serum thrombopoietin level was not correlated with serum IL-6 levels in any group. Serum thrombopoietin and IL-6 levels had no relationship with platelet count and with Child-Pugh score. CONCLUSIONS: Our study showed that cirrhotic patients with HCV had lower platelet count than those with HBV and controls, and this difference does not appear to be related with either serum thrombopoietin or IL-6 level.

BACKGROUND: Infection is a serious complication of nutritional support, causing a high rate of mortality and morbidity. Critically ill patients having nutritional support are prone to infectious complications. Questions regarding the effects of the route of nutrition in infectious complications have been asked. We aimed to determine the relationship between the route of nutrition and the risk of developing infectious complications in severely ill patients on nutritional support in an intensive care unit. METHODS: A retrospective review was performed on the files of 144 severely ill patients who had either enteral or parenteral nutrition during follow-up in an intensive care unit. The primary diagnoses of patients were heterogenous. RESULTS: Sixty-eight (35.8%) of them acquired novel infections during the hospitalization period. Forty-nine and 19 of the 68 infected patients had enteral and parenteral nutrition support, respectively. Seventy-six (40%) of the patients were free of infection. Fifty-one of 76 infection-free patients had enteral nutrition support, and 25 of them had parenteral nutrition support. Pulmonary infections, urinary tract infections, catheter infections and septicemia were the most frequent types of infectious complications. There was no significant difference in the rate of infectious complications between enteral nutrition and parenteral nutrition groups (p > 0.05). CONCLUSION: We conclude that the route of the nutritional support in severely ill patients having nutritional support in an intensive care unit does not affect the rate of infectious complications. We think that comorbid medical conditions and the need of intensive care unit support are more important parameters that determine the risk of development of infectious complications.

Recently, continuous venovenous hemodiafiltration (CVVHDF) and plasmapheresis (PF) were suggested as supportive therapy options in combination with standard treatment in advanced liver failure. The aim of this study was to analyze the effects of supportive extracorporeal treatment (SET) in a group of patients with advanced hepatic failure. A total of 25 patients (7 women, 18 men; mean age, 39.3+/-15.4 years; 13 were transplant recipients [6 women, 7 men; mean age, 37.7+/-16.9 years]) were included. All patients were in hepatic coma and receiving standard coma and liver failure management when they received SET. Number of SET sessions; levels of serum blood urea nitrogen, creatinine, albumin, calcium, phosphorus, ammonia, alanine and aspartate aminotransferase, and total/conjugated bilirubin; and prothrombin times (PTT) before and after SET were recorded retrospectively. 7.7+/-7.9 SET sessions were performed. Thirteen liver transplant recipients required SET for an average of 9.7+/-8.3 days after transplantation. Serum ammonia and bilirubin levels were lower after termination of supportive therapy when compared with initial levels (p<0.0001 and p<0.005 respectively). During follow-up, hepatic encephalopathy and liver failure resolved in 11 patients, while 14 patients (7 transplant recipients) died. There was no significant difference between patients in either group except that PTT was shorter in patients who survived (p<0.01). Further analyses revealed that in surviving patients, ammonia clearance was higher (p<0.01). In patients with advanced liver failure, or liver transplants, CVVHDF and/or PF could be supportive options combined with standard treatment.

AIM: A high rate of seropositivity for antibodies against Helicobacter pylori has been found in many extra-gastrointestinal diseases. In addition, it has been reported that the risk of chronic bronchitis may be increased in subjects infected with H. pylori. This study was designed to determine the H. pylori seroprevalence in patients with and without chronic bronchitis. MATERIALS AND METHODS: This study enrolled 68 patients with chronic bronchitis (40 men and 28 women, aged 50.5+/-16.2 years (mean+/-standard deviation) and 95 control subjects (60 men and 35 women, aged 51.8+/-15.9 years) matched for age and sex. An enzyme-linked immunosorbent assay immunoglobulin (Ig) G test for H. pylori diagnosis was performed on all enrolled subjects (those with chronic bronchitis and controls). RESULTS: Forty-five of 68 patients with chronic bronchitis (66.1%) and 48 of 95 subjects in the control group (57.7%) tested positive for H. pylori (P=0.008). Rates of H. pylori infection are higher in patients with chronic bronchitis than in the control group. CONCLUSION: The main conclusion of this study is that H. pylori infection is associated with an increased prevalence chronic bronchitis. Further studies should be planned to understand the potential pathogenetic mechanisms that might underlie this association.

BACKGROUND: : The following study aimed to clarify the importance of arginase and NOS activities in thioacetamide-induced hepatic damage and to evaluate the underlying mechanism of proposed protection provided by melatonin, using commonly applied therapeutic dose. METHODS: : Rats were randomly assigned to four groups (n=5): control, melatonin (10mg/kg i.p.), thioacetamide (200mg/kg i.p., two doses with a 24h interval) and thioacetamide+three doses of melatonin (10mg/kg i.p., prior- and post-treatment with a 24h interval before thioacetamide administrations) treated groups. RESULTS: : Thioacetamide administration caused hepatic damage creating oxidative and nitrosative stress accompanying perivenous necrosis and eosinophil infiltration. The significant elevation of total nitrite level in livers of thioacetamide treated groups reflected the activation of inducible nitric oxide synthase activity. The decrease in arginase activity indicated hepatic damage. Non-altered specific activity of arginase in the livers of thioacetamide treated groups did not overcome the elevation of NO production. Melatonin treatment did not modulate the levels/activities significantly. CONCLUSIONS: : Our results have indicated that nitrosative stress seems to be essentially critical in thioacetamide-induced hepatic failure in rats. Possible regulatory effect of arginase on NO production and applied dose of melatonin could not prevent hepatic damage.
RESUMEN
AIM: To evaluate susceptibility of Helicobacter pylori to amoxicillin and clarithromycin in end-stage renal disease (ESRD) patients and non-uremic controls. METHODS: The subjects with dyspeptic complaints were 33 ESRD patients and 46 age- and sex-matched non-uremic controls who exhibited H pylori on antral biopsy specimens. The two groups were age and sex matched. The H pylori strains' pattern of susceptibility to amoxicillin and clarithromycin was investigated with the agar dilution technique. RESULTS: None of the H pylori strains from either group showed resistance to amoxicillin with the agar dilution method. Twelve (36.4%) of the ESRD group strains and 7 (15.2%) of the control group strains showed resistance to clarithromycin, and this difference was statistically significant (P<0.05). CONCLUSION: Resistance to amoxicillin does not appear to be an important problem in H pylori-infected ESRD and non-uremic patients in our region. In contrast, the rates of resistance to clarithromycin are high, particularly in the ESRD population.

AIM: To evaluate the effects of Helicobacter pylori infection on gastric epithelial cell kinetics in patients with chronic renal failure (CRF). METHODS: Forty-four patients were enrolled in this study and divided into four groups with respect to their Helicobacter pylori (H pylori) and CRF status. Groups were labeled as follows: 1a: normal renal function, H pylori negative (n = 12), 1b: normal renal function, H pylori positive (n = 11), 2a: CRF, H pylori negative (n = 10), 2b: CRF, H pylori positive (n = 11). Upper gastrointestinal endoscopy was done in all the patients involved in the study. During endoscopical investigation, antral biopsy specimens were taken from each patient. In order to evaluate the cell apoptosis and proliferation in gastric epithelial cells, Bax and proliferating cell nuclear antigen (PCNA) labeling indexes (LI) were assessed with immunohistochemical staining method. RESULTS: For groups 1a, 1b, 2a, and 2b, mean Bax LI was identified as 34.4+/-13.7, 44.1+/-16.5, 46.3+/-20.5, 60.7+/-13.8, respectively and mean PCNA LI was identified as 36.2+/-17.2, 53.6+/-25.6, 59.5+/-25.6, 67.2+/-22, respectively. When the one-way ANOVA test was applied, statistically significant differences were detected between the groups for both Bax LI (P = 0.004 <0.01) and PCNA LI (P = 0.009 <0.01). When groups were compared further in terms of Bax LI and PCNA LI with Tukeyos HSD test for multiple pairwise comparisons, statistically significant difference was observed only between groups 1a and 2b (P = 0.006 <0.01). CONCLUSION: In gastric epithelial cells, expression of both the pre-apoptotic protein Bax and the proliferation marker PCNA increase with H pylori infection. This increase is more evident in patients with uremia. These findings suggest that uremia accelerates apoptosis and proliferation in gastric epithelial cells.

AIM: To determine whether Helicobacter pylori (H pylori)infection caused hyperhomocysteinemia by altering serum vitamin B(12), serum folate and erythrocyte folate levels and whether eradication of this organism decreased serum homocysteine level. METHODS: The study involved 73 dyspeptic H pylori-positive patients, none of them had gastric mucosal atrophy based on rapid urease test and histology. Out of 73 patients, 41 (56.2%) showed a successful eradication of H pylori 4 wk after the end of treatment. In these 41 patients, fasting serum vitamin B(12), folate and homocysteine levels, and erythrocyte folate levels before and 4 wk after H pylori eradication therapy were compared. RESULTS: The group with a successful eradication of H pylori had significantly higher serum vitamin B(12) and erythrocyte folate levels in the post-treatment period compared to those in pre-treatment period (210+/-97 pg/mL vs 237+/-94 pg/mL, P<0.001 and 442+/-212 ng/mL vs 539+/-304 ng/mL, P = 0.024, respectively), but showed no significant change in serum folate levels (5.6+/-2.6 ng/mL vs 6.0+/-2.4 ng/mL, P = 0.341). Also, the serum homocysteine levels in this group were significantly lower after therapy (13.1+/-5.2 micromol/L vs 11.9+/-6.2 micromol /L, P = 0.002). Regression analysis showed that serum homocysteine level was positively correlated with age (P = 0.01) and negatively with serum folate level before therapy (P = 0.003). CONCLUSION: Eradication of H pylori decreases serum homocysteine even in patients who do not exhibit gastric mucosal atrophy. It appears that the level of homocysteine in serum is related to a complex interaction among serum vitamin B(12), serum folate and erythrocyte folate levels.

AIM: The eradication rate of Helicobacter pylori (H pylori) shows variation among countries and regimens of treatment. We aimed to study the eradication rates of different regimens in our region and some factors affecting the rate of eradication. METHODS: One hundred and sixty-four H pylori positive patients (68 males, 96 females; mean age: 48+/-12 years) with duodenal or gastric ulcer without a smoking history were included in the study. The patients were divided into three groups according to the treatment regimens. Omeprazole 20 mg, clarithromycin 500 mg, amoxicillin 1 g were given twice daily for 1 week (Group I) and 2 weeks (Group II). Patients in Group III received bismuth subsitrate 300 mg, tetracyline 500 mg and metronidazole 500 mg four times daily in addition to Omeprazole 20 mg twice daily. Two biopsies each before and after treatment were obtained from antrum and corpus, and histopathologically evaluated. Eradication was assumed to be successful if no H pylorus was detected from four biopsy specimens taken after treatment. The effects of factors like age, sex, H pylori density on antrum and corpus before treatment, the total H pylori density, and the inflammation scores on the rate of H pylori eradication were evaluated. RESULTS: The overall eradication rate was 42%. The rates in groups II and III were statistically higher than that in group I (P<0.05). The rates of eradication were 24.5%, 40.7% and 61.5% in groups I, II and III, respectively. The eradication rate was negatively related to either corpus H pylori density or total H pylori density (P<0.05). The median age was older in the group in which the eradication failed in comparison to that with successful eradication (55 yr vs 39 yr, P<0.001). No correlation between sex and H pylori eradication was found. CONCLUSION: Our rates of eradication were significantly lower when compared to those reported in literature. We believe that advanced age and high H pylori density are negative predictive factors for the rate of H pylori eradication.

Transient increased intra-abdominal pressure (IIAP) due to carbon dioxide insufflation is suspected to cause a form of ischemia-reperfusion injury. Considering this, a study was designed to assess the effect of transient IIAP on liver regeneration in a rat model. Six groups of animals (each n = 6) were studied. While experiments in Group 1 (IIAP+PHR) were subjected to IIAP, following partial hepatic resection (PHR), those in Group 2 (IIAP) experiments were subjected to IIAP. Animals in Group 3 (IR+PHR) were subjected to liver ischemia-reperfusion (IR) following PHR, and those in Group 4 (IR) underwent only IR. Group 5 (PHR) and Group 6 (healthy) served as controls. Blood was taken for assessment of tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 with enzyme-linked immunosorbent assay (ELISA) at day 5 postoperatively. Each rat was then given a lethal injection of pentobarbital. Gravimetric analysis and immunohistochemistry staining for proliferating cell nuclear antigen (PCNA) were used for assessments of liver regeneration. Apoptosis was assessed by immunohistochemical TUNEL index, expressed as the number of positive cells/per total number of cells at the same time. Although mean liver regeneration rates of Group 1 and Group 3 were the same, that of Group 5 was the highest (p = .04). Serum TNF-alpha levels of Group 1 versus Group 3 were 340 pg/ml versus 352 pg/ml. Serum IL-l levels of Group 1 versus Group 3 were 124 pg/ml versus 135 pg/ml. Serum TNl-alpha and IL-6 levels of Group 1 and Group 3 were the same at the first day of surgical procedure (p > .05). Mean serum TNF-alpha levels of Group 5 (387 pg/ml) were significantly higher than those of both Group 1 and Group 3 at 24 h of operation. Serum IL-6 levels of Group 5 (174 pg/ml) at the same time was higher than those of Group 1 and Group 3 at the same time (p = .01). Proliferating cell nuclear antigen indices of Group 1, Group 2, Group 3, Group 4, and Group 6 were the same; however, the mean PCNA-labeling index of Group 5 was higher than those of the others. There were no significant differences between the groups (p > .05). Liver regeneration is suppressed by transient IIAP. However, the effect of IIAP on liver apoptosis needs to be clarified.

Hepatic lymphoma metastasis is rare, and should always be considered in the differential diagnosis of hepatic malignancy. A 52-year-old man presented with a four-day history of fever, fatigue, yellowish skin and nausea. His past medical history was unremarkable. There was no history of alcohol intake or medications. His physical examination revealed generalized jaundice and hepatomegaly. His blood tests showed liver failure and coagulopathy. Abdominal ultrasonography illustrated hepatomegaly. A further work-up included bone marrow and liver biopsy. The pathology report was B-cell lymphoma. He was treated with chemotherapy, and his laboratory findings during follow-up showed steady improvement. In conclusion, lymphoma metastasis to liver can be a cause of liver dysfunction. A high index of suspicion is required for the diagnosis. We emphasize the importance of obtaining tissue sample in all patients with suspicious lesion in any organ to avoid missing the rare but curable pathologies.

Pancreatic fistula is a potential complication of trauma or inflammation of the pancreatic duct or accessory pancreatic ducts. These fistulous tracts tend to form external to the pancreas; internal cases are rare. Pharmacological inhibition of pancreatic exocrine secretion and conservative approaches such as percutaneous endoscopic interventions are widely used to treat pancreatic fistulae. However, these fistulae are still associated with significant mortality and morbidity. In this report, we describe a case with post-splenectomy pancreatic fistulae and related recurrent abdominal abscess who was successfully managed with long-acting somatostatin.

An 85-year-old woman was admitted to our hospital due to pain and swelling in her right inguinal region. She had a right inguinal hernia. Abdominal computerized tomography revealed an 8 x 8 cm cecal mass and also a 13.5 cm segmental asymmetric nodular thickening of the cecum. Colonoscopic examination revealed a sessile polypoid mucus-secreting mass mimicking carcinoma that narrowed the cecal lumen. Histopathological examinations of sections from colonoscopic biopsy materials on light microscopy revealed villous adenoma morphology. The patient underwent operation, and an 18 x 6 x 4 cm mass, which partially obstructed the cecum, was seen. A right hemicolectomy was performed for complete excision. Histopathological examination revealed a pure villous adenoma, and there was no sign of malignant degeneration. On the 6th postoperative day, the patient was discharged from the hospital. During follow-ups at three-month intervals throughout one year, no abnormal colonoscopic or laboratory findings were assessed. We believe that, in older patients with inguinal hernia, presence of intraabdominal mass should be considered. Furthermore, we showed in this report that villous adenomas can reach significant dimensions without causing any obstructing signs or electrolyte imbalance and can mimic colon carcinoma.

Fasciola hepatica infestation is known to cause bile duct inflammation and biliary obstruction. Endoscopic retrograde cholangiopancreatography shows distinct features in some patients with fascioliasis, but the condition may be overlooked in chronic cases. The endoscopic retrograde cholangiopancreatograpy images must be carefully examined to rule out other possible causes of irregularity and thickening of the common bile duct wall. Parasite removal during endoscopic retrograde cholangiopancreatograpy is one therapeutic option in patients with acute obstructive cholangitis due to F. hepatica. We present a case of fascioliasis-induced acute cholangitis that was diagnosed and treated via endoscopy. A review of the literature on extraction of living parasites is also included.

Duodenal varices that develop in patients with portal hypertension rarely cause hemorrhage, but varix rupture is a serious and often fatal event. We report the case of a 38-year-old man with hepatic vein occlusion who was referred to our hospital for gastrointestinal hemorrhage of unknown origin. Upper gastrointestinal endoscopy revealed varices in the distal third of the duodenum. These varices were identified as the source of the bleeding. The patient was treated with endoscopic band ligation, and with coil embolization of a shunt between the superior mesenteric vein and the left renal vein.

BACKGROUND/AIMS: The aim of this study was to assess the frequency of vitamin B12 deficiency in patients with non atrophic gastric mucosa and any relationship between the presence of vitamin B12 deficiency and demographic, hematologic, and histopathologic parameters. METHODS: Three hundred and ten patients with no gastric mucosal atrophy on histologic evaluation were included in the study. Chronic inflammation, neutrophil activity and H. pylori load were scored using the Sydney classification system. Variables that might influence or predict the presence of vitamin B12 deficiency (age, gender, hemoglobin, mean corpuscular volume, serum folate level, scores of histologic parameters) were evaluated by univariate/multivariate analysis. RESULTS: The percentages of patients with vitamin B12 concentrations of < 250 pg/mL, < 200 pg/mL, and =100 pg/mL were 67.4%, 46.8% and 6.5% respectively. Patient age and all three histologic were inversely related to vitamin B12 deficiency (p<0.05). By multivariate analysis, factors independently associated with serum vitamin B12 deficiency were age and antral H. pylori load (p<0.05). CONCLUSIONS: The higher frequency of vitamin B12 deficiency in this study compared with a western study may be a reflection of the effect of H. pylori infection on serum vitamin B12 level. In addition, age was shown to be an independent risk factor for vitamin B12 deficiency irrespective of gastric atrophy. It is already known that the presence of H. pylori on gastric mucosa influence serum vitamin B12 levels. Hematologic parameters are not useful in predicting the deficiency of this vitamin.
