BACKGROUND AND AIM:The postinfectious irritable bowel syndrome (PI-IBS) frequently follows bacterial infections. Since people suffering from PI-IBS and Trichinella spiralis–infected mice develop similar findings, this animal model has been successfully used for PI-IBS studies; however, IBS has never been studied in humans after trichinellosis. The aim of this study was to evaluate the IBS symptoms in people who had acquired trichinellosis.PATIENTS AND METHODS:A large outbreak of trichinellosis caused by Trichinella britovi occurred in Izmir, Turkey, in 2003–2004. The diagnosis of trichinellosis was confirmed by serology and muscle biopsy. After clinical and laboratory evaluations, 72 patients (38 women, 34 men, mean age 33.2 ± 10.4 yr) with trichinellosis without preexisting IBS were enrolled in the study. Noninfected people (N = 27) were used as control group. A questionnaire was developed to assess symptoms of IBS and alarm symptoms. The first interview was done face-to-face. After 2, 4, and 6 months of the first interview, the questionnaire was readministered to the patients without any information on the occurrence of a previous trichinellosis syndrome, while it was applied after a year only to the patients who had suffered IBS symptoms according to at least one of the previous interviews.RESULTS:According to Rome II criteria, PI-IBS developed in 10 of 72 (13.9%) people with confirmed trichinellosis, who had no preexisting IBS. The rate of PI-IBS was 13.9% and 13.9% at the 4th and 6th months, respectively. The symptoms of PI-IBS persisted in five of them up to 1 yr. People without trichinellosis did not develop any IBS symptoms.CONCLUSIONS:This is the first report of the development of PI-IBS after T. britovi. Consequently, IBS can be considered as a secondary syndrome induced by trichinellosis.

Introduction:  Mutations of hepatitis B virus (HBV) polymerase, especially occurring at the highly conserved YMDD region, are related to resistance to lamivudine. Although these mutations are frequently secondary to lamivudine use, they can also occur naturally. The aim of the present study was to determine the prevalence of YMDD variants that exist naturally in patients who are inactive HBV carriers.

Relationship between non-steroidal anti-inflammatory drug use and Helicobacter pylori infection in bleeding or uncomplicated peptic ulcers: A case-control study.

Abdullah Okan; Ethem Tankurt; Belgin Ünal Aslan; Hale Akpinar; Ilkay Simsek; Omur Gonen

Background and Aims: Non‐steroidal anti‐inflammatory drug (NSAID) use has been closely associated with an increased risk of bleeding peptic ulcers, while the prevalence of Helicobacter pylori infection has been reported to be lower in bleeding ulcers than in non‐bleeding ones. However, whether an interaction exists between NSAID use and H. pylori infection has not clearly been elucidated yet. The aims of this study were to determine the frequency of NSAID use and H. pylori infection, to predict risk factors in bleeding peptic ulcers and to determine whether NSAID use and H. pylori infection interact with each other.

Can Gönen; Ilkay Simsek; Sulen Sarioglu; Hale Akpinar

Background:  It has been shown that standard endoscopic features often labeled as gastritis has a poor correlation with histopathology. Recently, high resolution magnifying endoscopy has been reported to be an effective method to diagnose gastritis. The aim of the present study was to compare standard endoscopy with magnifying endoscopy for the diagnosis of Helicobacter pylori gastritis, and to determine whether gastritis can be diagnosed based on findings at magnification endoscopy.

BACKGROUND The aim of the present study was to investigate serum leptin levels in relation to anthropometric features in patients with liver cirrhosis (LC) and chronic viral hepatitis (CVH), and to determine the effect of the severity and aetiology of the LC on serum leptin levels. METHODS Forty-nine patients with LC, 32 patients with CVH and 69 control subjects were age, body mass index (BMI) and sex-matched and included in the study. Plasma glucose, serum leptin and insulin levels were determined. Insulin resistance was assessed using homoeostasis model assessment (HOMA). Body composition was estimated by skinfold thickness. RESULTS Female patients with Child-A LC had higher levels of leptin, and female and male patients with Child-A LC had higher absolute leptin (leptin/BFM) levels compared to patients with Child-C LC and control subjects. Serum leptin levels of the patients with alcohol LC were higher than the control subjects, but the absolute leptin levels were comparable. When alcoholic and post-viral hepatitis cirrhotic patients were compared with each other on an aetiologic basis, there was no significant difference between them in leptin and absolute leptin levels. There were significant correlations between leptin and BMI, body fat percentage (BFP), BFM (body fat mass) in all three groups in both sexes. CONCLUSIONS These data suggest that the physiologic correlations among serum leptin level, sex, BMI and BFM were well preserved in patients with chronic liver disease. Patients with alcohol LC had higher leptin levels. In early stages of liver disease, leptin levels and absolute leptin levels are higher than in normal subjects. However, in advanced stages of the disease the significant decline in leptin levels and similar levels of leptin expressed in relation to BFM compared to control subjects predominantly represent the expression of fat mass.Background: The aim of the present study was to investigate serum leptin levels in relation to anthropometric features in patients with liver cirrhosis (LC) and chronic viral hepatitis (CVH), and to determine the effect of the severity and aetiology of the LC on serum leptin levels.

Background and aimsIn this study, we investigated whether reticulated platelets (RP) would be useful markers in the evaluation of ulcerative colitis (UC) activity and also aimed to gain indirect information about the platelet kinetics.Materials and methodsComplete blood count, C-reactive protein, erythrocyte sedimentation rate, and proportion of RP were measured in 16 active, 21 inactive UC patients, and 20 healthy blood donors. UC activity was assessed by Truelove–Witts criteria.ResultsMean platelet count was increased in patients with active compared to inactive UC (p = 0.008) or healthy donors (p = 0.000). Mean platelet volume (MPV) was significantly decreased in patients with active compared to inactive (p = 0.015) and healthy donors (p = 0.001). RP values was significantly decreased in active and inactive UC groups compared to healthy donors (p = 0.000, p = 0.000, respectively), while there was no significant difference between active and inactive UC patients (p = 0.980). Significant negative correlation between platelet count and MPV in patients with active UC (r = −0.542, p = 0.030) was observed.ConclusionsRP values is reduced in active and inactive UC patients compared to healthy donors. To our knowledge, this is the first study about proportion of RP with UC in literature. However, the role of low RP values have not been determined clinically. Further studies are needed to evaluate the role of platelet abnormalities and changes in megakaryopoiesis caused by inflammatory state on low MPV and RP values during the course of UC.

Rheumatic manifestations are the most common extraintestinal findings of inflammatory bowel disease (IBD), although there are wide variations among different studies. The only previous Turkish study reported a rather high prevalence of spondyloarthritis (SpA) in patients with IBD. We aimed to determine the frequency of SpA and ankylosing spondylitis (AS) in patients with IBD attending a gastroenterology clinic from a referral centre. The study was conducted in 122 patients with established diagnosis of IBD [28 with Crohn’s disease (CD) and 94 with ulcerative colitis (UC)]. A detailed medical history was obtained and a complete physical examination was performed in all the patients. Standard pelvic X-rays for examination of the sacroiliac joints were performed only when clinically indicated. The X-rays were read blindly by an experienced rheumatologist and reported according to the established grading system. The modified New York criteria were used to classify AS, and the European Spondyloarthropathy Study Group criteria for SpA. The prevalence of AS and SpA in patients with IBD was 8.2 and 28.7%, respectively. SpA was found to be significantly more common in the patients with CD compared to patients with UC, but the frequency of AS was not different between these two groups. There was no correlation between localisation or extent of the intestinal inflammation and presence of AS and SpA. A higher frequency of women was observed in patients diagnosed as SpA. Almost half of the patients with SpA (45.7%) had not been diagnosed before the study, although they had a history of IBP and/or peripheral arthritis. This study suggests that the prevalences of SpA and AS in Turkish patients with IBD are similar to those in many other populations. There may be a significant female predominance of SpA among patients with IBD.

Mesalazine-induced myopericarditis in a patient with ulcerative colitis

Levent Doganay; Baris Akinci; Nihat Pekel; Ilkay Simsek; Hale Akpinar

Dear Editor: Cardiac involvement is an uncommon condition seen during the course of inflammatory bowel disease [1]. The pathogenesis of myopericarditis in inflammatory bowel disease has not yet been clearly identified. It has also been described as a side effect of the treatment of inflammatory bowel disease with 5-ASA and mesalazine [2]. A 21-year-old man recently diagnosed with ulcerative colitis on the basis of endoscopic and pathological findings was admitted to our hospital because of uncontrollable bloody diarrhea. He was on mesalazine (2 g/day) for 10 days. He complained of bloody diarrhea ten times a day. Physical examination was unremarkable. The laboratory data were within the normal range with the exception of the erythrocyte sedimentation rate, which was 21 mm/h, and C-reactive protein, which was 14 mg/l (normal 0–5 mg/l). He was considered to have active disease and budesonide (9 mg/ day) was added to the mesalazine. On the 2nd day of admission the patient had fever of 38.4°C. The ECG was normal. The chest X-ray did not show any signs of infection. Blood cultures were negative. Three days later the patient developed tachycardia and dyspnea on minimal exertion. The ECG showed ST-segment elevations in leads V2–V4, T wave inversions and biphasic Twaves in leads V4–V6. A pericardial rub was heard. Echocardiography showed global hypokinesia with decreased ejection fraction (EF) to 41%. Inferior and posterior pericardial leaflets had increased echogeneity. Cardiac troponin I and CK-MB were elevated (2.6 and 9.7 ng/ml respectively). Tuberculin skin test and the serological examinations for antinuclear antibodies (ANA) and rheumatoid factor (RF) were negative. Polymerase chain reaction (PCR) test for enterovirus RNA was negative in the nasopharynx. The patient was diagnosed with acute myopericarditis and mesalazine was stopped, as it was considered a possible etiologic agent. One week after the drug was stopped, the chest pain had gone, and the ECG showed normal findings. Cardiac troponin I and CK-MB decreased to normal levels. Repeated echocardiography revealed an EF of 67%. More than 100 inflammatory bowel disease patients have been reported to have associated cardiac diseases as extra-intestinal manifestations of inflammatory bowel disease or as a consequence of drug-induced side effects [4]. Once the patient is on inflammatory bowel disease therapy it is usually problematic to determine the cause of cardiac involvement. In our case the symptoms resolved without any treatment following withdrawal of mesalazine, so we assume that mesalazine was the causative agent for myopericarditis. In the reported cases reviewed it is generally recommended to administer L. Doganay . B. Akinci Department of Internal Medicine, Faculty of Medicine, Dokuz Eylul University, Izmir, Turkey

BACKGROUND Insulin-like growth factor-I is a liver-derived humoral factor, which has important anabolic and metabolic actions and is predominantly bound by insulin-like growth factor binding protein-3. Low serum concentrations of both insulin-like growth factor-I and insulin-like growth factor binding protein-3 have been reported in patients with chronic liver disease, especially cirrhosis, but their conditions in chronic hepatitis are uncertain. The aim of this study was to evaluate the effect of chronic hepatitis on serum concentrations of insulin-like growth factor-I and insulin-like growth factor binding protein-3 and their association with hepatic inflammation activity and fibrosis. METHODS Serum insulin-like growth factor-I and insulin-like growth factor binding protein-3 were measured by RIA (ng/ml) in 17 patients with mild to severe chronic viral hepatitis (12 chronic hepatitis C, 5 chronic hepatitis B) and 16 healthy subjects. The hepatic inflammation activity and the severity of fibrosis were evaluated using Desmet classification. RESULTS Both insulin-like growth factor-I and insulin-like growth factor binding protein-3 levels did not correlate with inflammation activity, fibrosis or transaminase levels. In the chronic hepatitis group, insulin-like growth factor-I levels were significantly higher than the control group (mean, 263.8 +/- 27.33 versus 127.14 +/- 10.83 ng/ml, P < 0.001, respectively), whereas insulin-like growth factor binding protein-3 levels were significantly lower when compared with the controls (1643.47 +/- 60.68 versus 2728.87 +/- 284.61 ng/ml, P < 0.05, respectively). CONCLUSIONS These results suggest that the concomitant states of serum insulin-like growth factor-I and insulin-like growth factor binding protein-3 levels in patients with chronic hepatitis may be different from cirrhotic patients and high serum IGF-I levels may be a specific finding of the stage of chronic hepatitis before developing cirrhosis.

AIM To investigate the effects of Saccharomyces boulardii (S. boulardii) in an experimental rat model of trinitrobenzene sulfonic acid (TNBS)-induced colitis. METHODS Thirty-two Wistar albino female rats were categorized into five groups. On the first day of the study, 50 mg TNBS was administered via a rectal catheter in order to induce colitis in all rats, except those in the control group. For 14 d, the rats were fed a standard diet, without the administration of any additional supplements to either the control or TNBS groups, in addition to 1 mg/kg per day S. boulardii to the S. boulardii group, 1 mg/kg per day methyl prednisolone (MP) to the MP group. The animals in the S. boulardii + MP group were coadministered these doses of S. boulardii and MP. During the study, weight loss, stool consistency, and the presence of obvious blood in the stool were evaluated, and the disease activity index (DAI) for colitis was recorded. The intestines were examined and colitis was macro- and microscopically scored. The serum and tissue levels of tumor necrosis factor-α (TNF-α) and nitric oxide (NO) were determined, and fungemia was evaluated in the blood samples. RESULTS The mean DAI scores for the MP and S. boulardii + MP groups was significantly lower than the TNBS group (3.69 ± 0.61 vs 4.46 ± 0.34, P = 0.018 and 3.77 ± 0.73 vs 4.46 ± 0.34, P = 0.025, respectively). While no significant differences between the TNBS and the S. boulardii or MP groups could be determined in terms of serum NO levels, the level of serum NO in the S. boulardii + MP group was significantly higher than in the TNBS and S. boulardii groups (8.12 ± 4.25 μmol/L vs 3.18 ± 1.19 μmol/L, P = 0.013; 8.12 ± 4.25 μmol/L vs 3.47 ± 1.66 μmol/L, P = 0.012, respectively). The tissue NO levels in the S. boulardii, MP and S. boulardii + MP groups were significantly lower than the TNBS group (16.62 ± 2.27 μmol/L vs 29.72 ± 6.10 μmol/L, P = 0.002; 14.66 ± 5.18 μmol/L vs 29.72 ± 6.10 μmol/L, P = 0.003; 11.95 ± 2.34 μmol/L vs 29.72 ± 6.10 μmol/L, P = 0.002, respectively). The tissue NO levels in the S. boulardii, MP and S. boulardii + MP groups were similar. The mean serum and tissue TNF-α levels were determined to be 12.97 ± 18.90 pg/mL and 21.75 ± 15.04 pg/mL in the control group, 18.25 ± 15.44 pg/mL and 25.27 ± 11.95 pg/mL in the TNBS group, 20.59 ± 16.15 pg/mL and 24.39 ± 13.06 pg/mL in the S. boulardii group, 9.05 ± 5.13 pg/mL and 24.46 ± 10.85 pg/mL in the MP group, and 13.95 ± 10.17 pg/mL and 24.26 ± 10.37 pg/mL in the S. boulardii + MP group. Significant differences in terms of the levels of serum and tissue TNF-α and the macroscopic and microscopic scores were not found between the groups. S. boulardii fungemia was not observed in any of the rats. However, Candida fungemia was detected in one rat (14%) in the TNBS group, two rats (28%) in the S. boulardii group, three rats (50%) in the MP group, and three rats (42%) in S. boulardii + MP group. CONCLUSION S. boulardii does not demonstrate considerable effects on the DAI, pathological scores, or cytokine levels but does decrease the tissue NO levels.
