RESUMEN
Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder diagnosed on the basis of Rome IV criteria. Stress is an important contributor to the development of IBS symptoms, while personality, perceived self-efficacy, resilience, and coping strategies may be indirectly involved in the modulation of the body's response to various stressors. The aim of this study was to assess the effect of selected personality traits and stress with IBS symptoms. We enrolled 129 participants (59 men and 70 women) aged from 18 to 61 years. The study group included 94 patients with IBS, while the control group comprised 35 participants without a diagnosed psychosomatic disorder and chronic comorbidities. Participants were assessed using a self-designed questionnaire as well as the Coping Inventory for Stressful Situations, NEO-Five Factor Inventory, 25-item Resilience Coping Scale (Skala Pomiaru Preznosci - SPP-25), and General Self-Efficacy Scale. We observed a significant effect of personality, perceived self-efficacy, resilience, and coping strategies in patients with IBS. Moreover, stress was shown to be associated with disease severity, while the type of a coping strategy was related to the frequency of symptoms. The groups differed in terms of personality traits such as resilience, self-efficacy, extraversion, and neuroticism. Our study confirms the significant effect of personality traits and coping strategies in patients with IBS.

INTRODUCTION: Interactions between oral microbiota and systemic diseases have been suggested. We aimed to examine the composition of oral microbiota with reference to antioxidative defense and its correlation with clinical state in Crohn's disease (CD) in comparison to ulcerative colitis (UC). MATERIALS AND METHODS: Smears were taken from the buccal and tongue mucosa of patients with CD, UC and controls, and cultured with classical microbiology methods. Bacterial colonies were identified using matrix-assisted laser desorption/ionization (MALDI) with a time-of-flight analyzer (TOF). Blood morphology and C-reactive protein (CRP) were analyzed in the hospital laboratory. Antioxidative defense potential (FRAP) was determined using spectrophotometry in saliva and serum. RESULTS: Oral microbiota in CD patients were characterized by lower diversity in terms of the isolated bacteria species compared to UC and this correlated with reduced FRAP in the oral cavity and intensified systemic inflammation. Oral microbiota composition in CD did not depend on the applied treatment. In CD patients, a negative correlation was observed between the FRAP value in saliva and serum and the CRP value in serum. Individual differences in the composition of oral microbiota suggest that different bacteria species may be involved in the induction of oxidative stress associated with a weakening of antioxidative defense in the oral cavity, manifested by ongoing systemic inflammation. CONCLUSIONS: Analysis of both the state of the microbiota and antioxidative defense of the oral cavity, as well as their referencing to systemic inflammation may potentially prove helpful in routine diagnostic applications and in aiding a better understanding of CD and UC pathogenesis associated with oral microbiota.

Diagnostics of Crohn's disease (CD) requires noninvasive biomarkers facilitating early detection and differentiation of the disease. Therefore, in this study, we aimed to determine the relationship between paraoxonase-1 (PON-1), the severity of CD, oxidative stress, and inflammation in CD. The CD activity index was based on the current classification. Plasma PON-1 was measured in 47 patients with CD, and in 23 control volunteers. Using quantitative variables such as receiver operating characteristics (ROC) (area under the curve (AUC)), the diagnostic utility of PON-1 in differentiating the severity of CD was assessed. Circulating PON-1 was found to be decreased in the CD group compared to the control group (269.89 vs. 402.56 U/L, respectively), and it correlated well with the disease activity. PON-1 correlated positively with hemoglobin (Hb) (r = 0.539, p < 0.001), hematocrit (Ht) (r = 0.48, p < 0.001), total cholesterol (TC) (r = 0.343, p < 0.001), high density lipoprotein (HDL) (r = 0.536, p < 0.001), low density lipoprotein (LDL) (r = 0.54, p < 0.001), and triglyceride (TG) (r = 0.561, p < 0.001) and correlated negatively with white blood cell count (WBC) (r = -0.262, p = 0.029), platelet count (PLT) (r = -0.326, p = 0.006), C-reactive protein (CRP) (r = -0.61, p < 0.001), and malondialdehyde (MDA) (r = -0.924, p < 0.001). PON-1 as a marker for CD differentiation possessed a sensitivity and specificity of 93.62% and 91.30%, respectively. CD was found to be associated with the decrease in the levels of PON-1, which correlates well with activity of the disease and reflects the intensification of inflammation, as well as intensified lipid peroxidation. High sensitivity and specificity of PON-1 determines its selection as a good screening test for CD severity.

Oxidative stress (OxS) has been implicated in the pathogenesis of Crohn's disease (CD). The aim of this study was to examine whether nonenzymatic antioxidants are associated with active CD, by using the FRAP and GSH assay in plasma. Additionally, we measured bilirubin and albumin levels as two individual components of the plasma antioxidant system. A total of 55 patients with established CD, 30 with active CD and 25 with inactive disease, and 25 healthy individuals were prospectively enrolled in this study. We evaluated CD activity index, BMI and blood morphology, platelet count, serum CRP level, and bochemical parameters of OxS: ferric reducing ability of plasma (FRAP), reduced glutathione (GSH) in plasma and bilirubin and albumin levels in serum. Plasma FRAP and GSH concentrations were decreased in both CD groups compared to controls and negatively correlated with CDAI values (FRAP: r = -0.572, p = 0.003; GSH: r = -0.761, p = 0.001), CRP and platelet count. Bilirubin and albumin levels were lower in the serum of active CD patients than inactive CD patients and controls and negatively correlated with the CD activity index (r = -0328, p = 0.036, r = -0.518, p = 0.002) and CRP (r = -0.433, p = 0.002). e decreased FRAP and GSH levels in plasma and bilirubin and albumin levels in serum of patients with active CD compared to inactive CD and controls underlines the importance of OxS in the pathophysiology and activity of CD.

Over the past few years, the role of intestinal alkaline phosphatase (IAP) as a crucial mucosal defence factor essential for maintaining gut homeostasis has been established. IAP is an important apical brush border enzyme expressed throughout the gastrointestinal tract and secreted both into the intestinal lumen and into the bloodstream. IAP exerts its effects through dephosphorylation of proinflammatory molecules including lipopolysaccharide (LPS), flagellin, and adenosine triphosphate (ATP) released from cells during stressful events. Diminished activity of IAP could increase the risk of disease through changes in the microbiome, intestinal inflammation, and intestinal permeability. Exogenous IAP exerts a protective effect against intestinal and systemic inflammation in a variety of diseases and represents a potential therapeutic agent in diseases driven by gut barrier dysfunction such as IBD. The intestinal protective mechanisms are impaired in IBD patients due to lower synthesis and activity of endogenous IAP, but the pathomechanism of this enzyme deficiency remains unclear. IAP has been safely administered to humans and the human recombinant form of IAP has been developed. This review was designed to provide an update in recent research on the involvement of IAP in intestinal inflammatory processes with focus on IBD in experimental animal models and human patients.

BACKGROUND: Difficulties in diagnosis of inflammatory bowel disease (IBD) motivate the search for new diagnostic tools, including laboratory tests. The aim of this study was to evaluate concentrations of the neutrophil (NEU) proteins leukocyte elastase (HLE-α1AT), lactoferrin and calprotectin as potential biomarkers used in the diagnosis and assessment of clinical activity of Crohn's disease (CD) and ulcerative colitis (UC). MATERIAL/METHODS: The study included 27 patients with CD, 33 patients with UC and 20 healthy controls. Plasma concentrations of calprotectin, lactoferrin and HLE-α1AT were measured using ELISA. RESULTS: In patients with CD higher concentrations of HLE-α1AT (64.3±43.1 vs. 30.1±7.7 ng/l, P<0.001), calprotectin (151.6±97.8 vs. 69.9±22.1 ng/l, P<0.001) and lactoferrin (243.2±102.0 vs. 129.7±32.7 ng/l, P<0.001) than in the control group were found. In patients with UC higher plasma concentrations of HLE-α1AT (62.0±30.9 vs. 30.1±7.7 ng/l, P<0.001), calprotectin (149.6±72.3 vs. 69.9±22.1 ng/l, P<0.001) and lactoferrin (242.6±107.5 vs 129.7±32.7 ng/l, P<0.001) than in the control group were found. HLE-α1AT/NEU and lactoferrin/NEU ratios in patients with UC were significantly higher compared with patients with CD. Calprotectin (P=0.010) and lactoferrin (P=0.023) levels were higher in patients with the active compared with inactive phase of CD. CONCLUSIONS: The diagnostic characteristics of plasma granulocyte protein concentrations indicate the usefulness of these tests in the diagnosis of IBD. Higher HLE-α1AT and lactoferrin/NEU ratios in patients with UC than with CD may suggest the usefulness of these ratios in differential diagnostics. Plasma calprotectin and lactoferrin levels may be useful in CD activity assessment.

INTRODUCTION: Oxidative stress with an excessive free radical production and a reduction in the activity of protective antioxidants is considered as one of the mechanisms responsible for gluten toxicity. However, its role in celiac disease (CD) is unclear. OBJECTIVES: Evaluation of plasma nonenzymatic antioxidant capacity in patients with CD (both untreated patients and those receiving gluten-free diet [GFD]) by measuring the ferric reducing ability of plasma (FRAP) as well as assessing selected plasma antioxidants. PATIENTS AND METHODS: The study included 169 adult patients: 48 patients with untreated active CD, 72 patients with CD on a GFD, and 49 healthy controls. In each group, we measured the serum levels of selected antioxidants (uric acid, bilirubin, albumin, and vitamin E) and used the FRAP assay to assess the total antioxidant capacity (TAC) of plasma. In each patient, serological and histopathological activity of CD was also evaluated. RESULTS: There were no significant differences in the TAC of plasma measured with the FRAP assay between the study groups. Patients with CD had higher uric acid levels compared with controls (p <0.001), while bilirubin levels were lower in patients with active disease than in controls (p <0.05). Serum vitamin E levels were lower in all patients with CD compared with controls (p <0.01). CONCLUSIONS: The FRAP assay is not the method of choice for assessing the TAC of plasma in patients with CD. Owing to high serum uric acid levels, the FRAP assay results in these patients may be overestimated despite the reduced levels of other plasma antioxidants.

Introduction: Crohn's disease (CD) is a chronic inflammatory disease, which may involve any part of the gastrointestinal tract, including the oral cavity. Mucosal lesions in the oral cavity are described in various populations, but observations in active disease with severe clinical symptoms are quite rare. Objectives: To evaluate the prevalence and nature of oral mucosa lesions in adult patients with active CD and their correlation with clinical and laboratory indicators of disease activity. Material and Methods: Prospective study was performed in 62 patients (29 women, 33 men, age 18-49 years) admitted between December 2010 and February 2013 to the gastroenterology department with a confirmed diagnosis of CD and exacerbations of symptoms, and 40 sex- and gender-matched healthy volunteers. CD activity was classified according to clinical and blood parameters, and the CD activity index (CDAI). We examined: blood morphology, hemoglobin and CRP levels, BMI. Examination of the oral cavity included a detailed interview and physical examination, based on the WHO recommendations. Results: In patients with active CD we found: increased CDAI score (258.4±21.5), higher CRP levels (24.6±1.3 mg/l) and platelet count, anemia with significantly reduced RBC and hemoglobin level, and reduced BMI, in comparison to controls. The specific for CD symptoms were found in the mouth: indurated tag polypoid lesions on vestibular retromolar region in 12.9% of patients, cobblestoning of the mucosa in 9.7%, diffuse asymptomatic buccal swelling in 16.2%, mucogingivitis in 19.4% of patients. Oral nonspecific lesions were more frequent: angular cheilitis in 29.1%, atrophic glossitis in 14.5% of patients. Oral lesions correlated with hemoglobin and CRP concentrations (r=-0.431 and r=0.437; respectively; p<0.001), platelet count (r=0.45; p<0.003), CDAI (r=0.421; p<0.001) and BMI (r=0.307; p<0.006). No correlation has been found between specific or non-specific lesions and location of inflammatory changes in the gastrointestinal tract. Conclusions: Changes in the oral mucosa in adult patients with active CD are frequent. They should be correlated with other clinical symptoms of gastrointestinal tract and biochemical parameters in patients with CD. The nature of these changes may have an impact on the further therapeutic approach.

BACKGROUND/AIMS: The aim of the study was to analyze the effect of celiac disease(CED) on the upper-gut motility and release of enteral hormones (ghrelin and pancreatic peptide (PP)). MATERIALS AND METHODS: the study included 25 patients diagnosed with CED and 30 healthy controls. Gastric myoelectric activities (EGG) in a fasted and fed state were recorded. The plasma concentrations of ghrelin and PP were determined. R e s u l t s: CED patients presented in a fasted state a decreased percentage of normogastria 54.8 ± 24.5 vs. 86 ± 12.3%, p = 0.02 and slow wave coupling (SWC) 52.7 ± 13.4 vs. 77.4 ± 11.9%; p = 0.00001 with increased dominant power (DP) 11.6 ± 1.5 vs. 11.1 ± 1.1. Contrary to the controls, they did not show an improvement in the percentage of normogastria, DP and SWC when examined in a fed state (p ã0.05). Furthermore, CED patients presented with significantly lower fasting plasma concentrations of ghrelin 156.8 ± 86.7 vs. 260.2 ± 87.6 pg/ml, p = 0.0002 and significantly higher fasting PP levels than did the controls 265.2 ± 306.3 vs. 54.1 ± 54.6 pg/ml, p = 0.0005. C o n c l u s i o n: CED affects gastric myoelectric activity (decreasing normogastria and coupling) and causes changes in fasting concentrations of enteral hormones (decrease in ghrelin and an increase in PP). Gastric myoelectric response to food is abolished in CED patients, probably due to the neurohormonal changes induced by primary inflammation associated with this disease.

Introduction: Gastroesophageal reflux disease (GERD) is connected with body mass index (BMI) according to some recent studies. However, the link between overweight and severity of GERD symptoms is still unclear. Objectives: The aim of our study is to assess the influence of BMI on clinical presentation and occurrence of inflammatory changes in the esophagus in patients with GERD. Material and Methods: 121 clinically diagnosed GERD patients: 66 males (54.5%) and 55 females (45.5%), aged 19 89 years were involved in the study. After the detailed anamnesis BMI was counted and gastroscopy was performed. All individuals who agreed for upper endoscopy were divided into three groups. 42 patients (34.7%) were classified as Non-Erosive Reflux Disease (NERD), 53 patients (43.8%) were diagnosed with Erosive Esophagitis (EE), 11 patients (9.1%) with Barrett's esophagus (BE). Among EE group 34 patients were diagnosed with grade A of esophagitis according to Los Angeles scale, 17 with grade B, 2 with grade C and none with grade D. The differences between groups were assessed using statistical analysis. Results: The mean age of patients was 50.2±12.9 years and the mean BMI was 25.5±4.2 kg/m2. Patients with BE were older (61.2±12.0 years) than NERD (48.5±13.6 years); (p=0.028) and EE (50.4±11.4 years); (p=0.008). BE had higher BMI (27.0±4.4 kg/m2) as compared to NERD (24.0±3.3 kg/m2); (p=0.022) and EE (24.4±3.1 kg/m2); (p=0.048). Hiatal hernia was more frequent in EE and BE (79.2% and 90.9%, respectively) as compared to NERD (45.2%); (p<0.001). Patients EE and BE more frequently complained to heartburn (84.9% and 72.7%, respectively) than patients with no mucosal injury (42.9%); (p<0.001). Sleeping problems were encountered by patients with higher levels of BMI. Conclusion: This study demonstrates that overweight predispose to esophageal inflammation and increase the frequency of heartburn and sleep problems in GERD patients.

Background: In inflammatory bowel disease (IBD) the imbalance between cytokines pro- and antinflammatory is observed. The aim of this study was the assessment of interleukin-10 (IL-10), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) concentration usefulness in the evaluation of the activity of ulcerative colitis (UC) and Cohn's disease (CD). Methods: 35 patients diagnosed with UC and 39 with CD were examined. The control group (CG) consisted of 35 healthy volunteers. Diagnosis of the disease was confirmed by videocolonoscopy and histopathological evaluation of intestinal biopsies. Disease activity of UC was assessed according to the Mayo Scoring System and by the Crohn Disease Activiti Index (CDAI) in CD patients. Among patients with UC 18 (51%) had severe, 14 (40%) moderate and 3 (9%) mild disease. Among patients with CD 7 (18%) was diagnosed with high, 27 (69%) moderate, and 5 (13%) with low activity of the disease. WBC, PLT, serum concentration of TNF-α, IL-6 i IL-10 were determined. Results: The average concentration of TNF-α in UC patients was: 14.3 (IQR=12.6), in CD: 12.6 (IQR=11.9), in the CG: 3.1 (IQR=1.7). The average concentration of IL-6 in UC was: 19.6 (IQR=21), in CD: 10.8 (IQR=7.6), in CG : 3.2 (IQR=1.6). The average concentration of IL-10 in UC was: 14.4 (IQR=5.9), in CD: 10.4 (IQR=9.3), in the CG: 3.3 (IQR=2.5). In the IBD TNF-α, IL-6 and IL-10 concentration was significantly higher than in CG. However, IL-10 was significantly higher in UC than CD. In patients with UC statistically significant positive correlation between the concentration of TNF-α, IL-6 and IL-10 and disease activity was noticed. There were no correlation between TNF-α, IL-6 and IL-10 concentration and CD activity. Conclusion: Determination of TNF-α, IL-6 and IL-10 serum concentration can be used for noninvasive evaluation of inflammation activity in patients with IBD. IL-10 concentration may be helpful in differentiation of UC and CD.

World Health Organization (WHO) defines adverse drug reaction (ADR) as "a response to a drug which is noxious and unintended, and which occurs at doses normally used in man for the prophylaxis, diagnosis, or therapy of disease, or for the modifications of physiological function". ADRs are a serious problem of contemporary pharmacotherapy. Expenditures for treatment of ADRs in the United States may cost up to 30.1 billion dollars annually. Factors affecting the development of ADRs are: age, gender, body weight, polypharmacy. About 10% of ADRs is associated with gastrointestinal tract (GIT). ADR can affect every part of GIT. Xerostomia is the most common ADR occurring in oral cavity. ADRs affecting esophagus include irritation and inflammation of the mucosa. Approximately one-third of all cases of esophageal inflammation results from administration of non-steroid anti-inflammatory drugs (NSAIDs). The main cause of ulcerations involving stomach and small intestine are NSAIDs. Drug-induced diarrheas are the most common adverse effect accounting for approximately 7% of all observed cases of ADRs. They may be triggered by antibiotics, magnesium salts, laxatives and others. On the other hand, some groups of medications may induce constipation. These drugs comprise opioids, diuretics, calcium channel blockers, cholinolytics and others. Proton pump inhibitors, metformin, orlistat and colesevelam may lead to restricted absorption of certain vitamins and minerals. Physicians' knowledge about most popular and well documented ADRs can improve patients' safety and make pharmacotherapy more comfortable for them.

Although progress has been recently made in understanding of inflammatory bowel diseases (IBD), their etiology is unknown apart from several factors from adipose tissue and skeletal muscles such as cytokines, adipokines, and myokines were implicated in the pathogenesis of ulcerative colitis. We studied the effect high-fat diet (HFD; cholesterol up to 70%), low-fat diet (LFD; cholesterol up to 10%), and the normal diet (total fat up to 5%) in rats with TNBS colitis forced to treadmill running exercise (5 days/week) for 6 weeks. In nonexercising HFD rats, the area of colonic damage, colonic tissue weight, the plasma IL-1ß, TNF-α, TWEAK, and leptin levels, and the expression of IL-1ß-, TNF-α-, and Hif1α mRNAs were significantly increased and a significant fall in plasma adiponectin and irisin levels was observed as compared to LFD rats. In HFD animals, the exercise significantly accelerated the healing of colitis, raised the plasma levels of IL-6 and irisin, downregulated the expression of IL-1ß, TNF-α, and Hif1α, and significantly decreased the plasma IL-1ß, TNF α, TWEAK, and leptin levels. We conclude that HFD delays the healing of colitis in trained rats via decrease in CBF and plasma IL-1ß, TNF-α, TWEAK, and leptin levels and the release of protective irisin.

UNLABELLED: Both ulcerative colitis (UC) and primary sclerosing cholangitis (PSC) are chronic and progressive diseases of uncertain etiology, that may affect one patient. Approximately 70% of PSC cases are also diagnosed with UC, whereas in the group of UC the prevalence of PSC is about 2-5%. The aim of the study was to compare clinical courses of PSC and UC in patients diagnosed with both diseases to those with the confirmed diagnosis of either PSC or UC. Three groups were distinguished and evaluated: patients with PSC and UC (n = 17) and two control groups: patients with PSC (n = 4) and with UC (n = 13). Clinical data, symptoms, laboratory tests, results of the magnetic resonance cholangiopancreatography and colonoscopy were analyzed to compare clinical courses of these diseases between the groups. CONCLUSION: there is no correlation between clinical course of simultaneous PSC and UC. However, it may differ depending on co-occurrence of the other disease.

INTRODUCTION: The aim was to assess the usefulness of TGF-ß1 and elastase in the evaluation of activity of ulcerative colitis (UC) and Crohn's disease (CD). MATERIAL AND METHODS: 32 patients diagnosed with UC, 31 with CD and 30 healthy volunteers were enrolled in this study. Diagnosis of the disease was confirmed by videocolonoscopy and histopathological evaluation of intestinal biopsies. Disease activity was assessed by use of the Mayo Scoring System for Assessment of Ulcerative Colitis Activity in UC patients and by CDAI in CD patients. hsCRP was determined by the immunonephelometric method, TGF-ß1 and elastase plasma concentration by ELISA. The results of the study were analyzed using Statistica and R statistical language. RESULTS: In UC a positive correlation between disease activity and platelet level, hsCRP and TGF-ß1 concentration was noted. Elastase concentration in UC patients was significantly higher than in CD, but there was no correlation with the activity of the disease. In CD patients we observed a positive correlation between disease activity and leukocytes, platelet levels and elastase concentration, and a very low correlation with hsCRP and TGF-ß1. DISCUSSION: Determination of TGF-ß1 can be used for evaluation of inflammatory activity in UC and it is connected with elevated concentrations of CRP and platelets. To a lower extent TGF-ß1 can also be used for evaluation of inflammatory activity in CD. Examination of elastase concentration may be useful in the assessment of CD activity. Plasma elastase concentration may be helpful in UC and CD differentiation. The preliminary results of this investigation seem promising; nevertheless, more studies are necessary.

INTRODUCTION: Clostridium difficile infection (CDI) is a bacterial infection of the digestive tract. Acute infections are accompanied by increased risk for venous thromboembolism (VTE). To date, there have been no studies of the rheological properties of blood during the course of digestive tract infections. The aim of our study was to examine the effects of CDI on red blood cell (RBC) rheology, specifically RBC deformability, RBC aggregation, and plasma viscosity. In addition, the activity of glucose 6 phosphate dehydrogenase (G6PD) and acetylcholinesterase (AChE) in RBC was studied. MATERIALS AND METHODS: Our study group included 20 patients with CDI, 20 healthy persons comprised the control group. We examined the effects of CDI on the rheology of RBCs, their deformability and aggregation, using a Laser-assisted Optical Rotational Cell Analyzer (LORCA). Plasma viscosity was determined using a capillary tube plasma viscosymeter. Moreover, we estimated the activity of AChE and G6PD in RBC using spectrophotometric method. RESULTS: A statistically significant increase was found in the aggregation index, viscosity and activity of G6PD whereas the amount of time to reach half of maximum aggregation (t½) and the amplitude of aggregation (AMP) both showed statistically significantly decreases among patients with CDI compared to the control group. We also observed that the Elongation Index (EI) was decreased when shear stress values were low, between 0.3 Pa and 0.58 Pa, whereas EI was increased for shear stress in the range of 1.13-59.97 Pa. These observations were statistically significant. CONCLUSIONS: We report for the first time that acute infection of the gastrointestinal tract with Clostridium difficile is associated with abnormalities in rheological properties of blood, increased serum viscosity as well as increased aggregation of RBCs, which correlated with severity of inflammation. These abnormalities may be an additional mechanism causing increased incidence of VTE in CDI.

BACKGROUND: Hyperhomocysteinemia seems to be a common phenomenon in both patients with ulcerative colitis and Crohn's disease. Many factors including deficiencies of cobalamin, folate and pyridoxine, smoking habits, alcohol and coffee intake, some medications and age may predispose subjects to hyperhomocysteinemia. The study aimed to evaluate homocysteine levels in an inflammatory bowel disease cohort as dependent of life style and disease activity. METHODS: 85 consecutive patients with inflammatory bowel disease (38 with Crohn's disease and 47 with ulcerative colitis) and 65 control subjects were included in the prospective study. The following parameters were analyzed: disease activity, duration of the disease, location of pathological changes, presence of complications, current medications, past surgical procedures, smoking history, concomitant diseases, biochemical parameters and plasma homocysteine levels. RESULTS: Mild hyperhomocysteinemia was found in 16 patients with Crohn's disease (42%), 19 patients with ulcerative colitis (40%) and 19 patients in the control group (29%) (p = 0.59). There was not any significant correlation between homocysteine level and disease activity. Only folic acid supplementation and gender affected homocysteine level. Folic acid intake led to reduction of homocysteine levels in all groups of patients (11.8 micromol/l vs. 8.33 miccromol/l, p = 0.0065 in Crohn's disease patients and 10.94 micromol/l vs. 7.78 micromol/l, p = 0.0069 in ulcerative colitis patients). CONCLUSION: Homocysteine level in patients with inflammatory bowel disease is mostly normal or slightly elevated. Disease activity does not have an impact on homocysteine level. Folic acid is the most important factor having an influence on homocysteine level in patients with inflammatory bowel disease.

INTRODUCTION: Celiac disease (CD) is an autoimmunological gluten sensitive enteropathy occuring to genetically predisposed individuals. Active CD is accompanied by presence of multiple antibodies. Anti alpha enolase antibodies were reported in several autoimmunological disorders like rheumatoid arthritis, primary sclerosing cholangitis. Data about its presence and role in CD is avaricious. AIM: The aim of this study was to determine presence of anti alpha enolase antibodies in CD, correlation with gluten exposure, presence of anti tranglutaminase antibodies and Marsh scale. METHODS: Sera from 31 patients with CD (21 females, 10 males) and 6 healthy subjects were collected. Evaluation of CD activity and adherence to gluten free diet were obtained by serology tests (presence of endomyslum antibodies and/or anti transglutamineses in IgA or IgG classes) and histological hallmarks. Anti alpha enolase antibodies were identified in sera using ELISA kit. Titres of anti alpha enolase antibodies were identified among patients with newly diagnosed CD, CD patients non adhering to gluten free diet (GFD), adhering to GFD and among healthy subjects. RESULTS: Mean titre of anti alpha enolase antibodies was higher in CD patients (both treated and non treated) in comparison to control group, respectively 1.1 ng/mL, and 0.795 ngl mL. Among CD patients non adhering to gluten free diet mean titre was 1.4 ng/mL. CONCLUSIONS: Higher anti alpha enolase antibodies titres in non treated CD suggest usefulness of its measurement. These antibodies might be a novel marker of chronic inflammation among CD patients non adhering to GFD.

INTRODUCTION: Endoscopic examination of the upper gastrointestinal tract (upper GI) with macroscopic and histopathological evaluation provides essential tool to differentiate the organic and functional causes of dyspepsia. The distinction, however, is often smooth and not fully defined. The aim of this study was to assess the frequency and type of the macroscopic and histopathological changes in the upper GI endoscopy in patients with symptoms of dyspepsia. MATERIAL AND METHODS: A retrospective study was performed on 212 patients with dyspepsia, at the age of 18-84 years, including 60 patients to 45 years of age (group I) and 152 patients older than 45 (group II) who underwent gastroscopy. The severity of esophagitis was classified according to the Los Angeles Classification and gastritis according the updated Sydney system. Biopsy specimens were taken from the gastric and duodenum for histopathological examination. The presence of H. pylori infection has been established on the basis of histopathological examination and positive rapid urease test. RESULTS: Reflux esophagitis was found in 18 patients (8.5%), slightly more common in people over 45 years of age (group I--5%, group II--9.2%). The mild forms of esophagitis occurred most frequently. A more advanced form of inflammation and Barrett's esophagus was found only in patients over 45 years of age. Normal gastric and duodenal mucosa was revealed in 30% of patients in group I and 9.2% in group II. The most common endoscopic lesion was gastritis, mostly erythematous-exudative and less often atrophic. The presence of H. pylori infection was varied in the different types of inflammation. H. pylori infection occurred most frequently in the case of erosive and follicular gastropathy. The most common location of H. pylori infec- frequent in older patients. Peptic ulcer was found in 4.7% of patients (group I--5%, group II--4.6%). In one patient (61 years old) stomach cancer was diagnosed and in one patient (<45 years old) Crohn's disease of the upper GI was diagnosed. The majority of patients had normal duodenal mucosa. In 3.3% of patients (group I--8.3%, group II--1.3%), who had not previously diagnosed celiac disease, histopathological changes typical of celiac disease has been shown. In all patients, in whom biopsy specimens were taken from normal duodenal mucosa (14% of patients), histopathological examination revealed the presence of non-specific inflammation, regardless of the coexistence of H. pylori infection. CONCLUSION: Regardless of the severity of lesions of the upper GI endoscopy in patients with dyspepsia, it is advisable to take biopsy from the gastric and duodenal mucosa, which allows for an individualized management of these patients. Celiac disease should be considered in the diagnosis of the causes of dyspepsia. Further studies of microscopic duodenitis in patients with dyspepsia are needed.

BACKGROUND: In chronic viral hepatitis C, hepatocytes inflammation, necrosis and apoptosis occur. To evaluate hepatocyte apoptotic rate, a serum concentration of proapoptotic FaS protein and its ligand (FaS/FaSL) as well tumor necrosis factor-alpha (TNF-alpha) and antiapoptotic hepatocyte growth factor (HGF) may be used. The aim of the study was to evaluate the hepatic apoptosis rate in patients with hepatitis virus C infection and its correlations with the degree of liver inflammation and staging, biochemical tests, viral load and the duration of the infection. PATIENTS AND METHODS: 60 adults (30 chronic hepatitis C patients and 30 controls) were included into the study. Serum levels of FaS/FaSL, TNFalpha and HGF were evaluated using the ELISA method. The results were correlated with viral load, biochemical tests, as well ultrasonographic and histopathological (grading, staging) examinations. RESULTS: TNF-alpha level in HCV-infected patients was significantly higher than in the controls (11.0 +/- 19.3 pg/ml vs. 3.3 +/- 2.8 pg/ml, p = 0.04). FaS/ FaSL and HGF did not differ significantly in both groups. TNF-alpha level was higher in patients with low staging (fibrosis F-0) than in those with higher staging (F-1, F-2, F-3)--according to the Batts-Ludwig scale. Other markers (FaS/FaSL and HGF) did not differ in groups with variant staging. No significant differences were observed in relation to grading. CONCLUSIONS: The measurement of FaSIFaSL, TNF-alpha and HGF does not allow for the assessment about apoptotic rate in patients with chronic hepatitis C. Explanation of this problem need follow-up studies on larger groups with the use of more complex methods.
