Abstract
BACKGROUND Previous data collected in separate studies using various different survey instruments have suggested some variability in the prevalence of symptoms between nations. However, there is a lack of studies which assess and compare the prevalence of upper gastrointestinal symptoms contemporaneously in various countries using a uniform, standardised method. AIM To determine the prevalence of upper gastrointestinal (UGI) symptoms in 13 European countries, and the association between socioeconomic factors and symptoms using a standardised method. METHODS A representative age- and gender-stratified sample of 23,163 subjects (aged 18-69 years) was surveyed. RESULTS The prevalence of UGI symptoms was 38%. UGI symptoms were most prevalent in Hungary [45%, 95% confidence interval (CI): 42.2-48.4] and lowest in the Netherlands (24%, 95% CI: 21.0-26.2). UGI symptoms were more prevalent in women (39%, 95% CI: 38.4-39.6) vs. men (37%, 95% CI: 36.4-37.6). Heartburn (24%, 95% CI: 23.4-24.6) and acidic reflux (14%, 95% CI: 13.6-14.4) were most common. With age, the prevalence of UGI symptoms decreased (e.g. 18-29 years: 43%, 95% CI: 41.4-44.3 vs. 50-69 years: 33%, 95% CI: 32.3-34.4); in contrast, the frequency of symptom episodes/year increased with age (e.g. 18-29 years: 11.3 episodes per years, 95% CI: 10.5-12.1 vs. 50-69 years: 21.8, 95% CI: 20.7-22.9). Socioeconomic status as measured by gross domestic product was inversely associated with symptoms and in total, socioeconomic factors, gender, body mass index, smoking habits and alcohol consumption explained 83% of the variance of UGI symptoms. CONCLUSIONS There are marked differences in the country specific prevalence of upper gastrointestinal complaints. Socioeconomic factors are closely associated with the prevalence of upper gastrointestinal symptoms.

Abstract
BACKGROUND Functional dyspepsia (FD) is now categorized into the epigastric pain syndrome (EPS) and the postprandial distress syndrome (PDS). However, the role of disturbed gastric emptying and sensory function for the reduction of health-related quality of life (HRQOL) has not yet been studied in EPS and PDS. METHODS A total of 300 refractory FD patients and 450 healthy blood donors (BD) were studied. BD were stratified in subjects with (BD+) and without (BD-) concomitant FD symptoms. Gastric motor and sensory function, generic and disease-specific HRQOL [physical (PCS) and mental component summary (MCS)] and affective disorders were assessed. Twenty randomly selected BD-, 50 BD+ (36 PDS, 72%), and 110 FD (95 PDS, 86.4%) patients had additional function testing. KEY RESULTS Health-related quality of life was significantly reduced in FD patients (PCS = 40.7 +/- 8.8, MCS = 39.7 +/- 11.3, both P < 0.0001) compared to BD+ (PCS = 52.0 +/- 7.6, MCS = 49.0 +/- 9.4) and BD- (PCS = 56.0 +/- 4.3, MCS = 52.8 +/- 7.2). GET (t((1/2)), min) was significantly (both P < 0.0001) longer in FD patients (143.0 +/- 7.3) compared to BD+ (101.1 +/- 6.3) and BD- (73.8 +/- 7.6). FD patients scored significantly higher for 'pain' (P < 0.0001) and 'nausea' (P = 0.023), there was no difference for 'fullness' compared to BD. Impairment of GET was not associated with HRQOL. In FD patients, an augmented symptom response to the test meal (fullness, nausea) was associated with MCS, there was no difference between FD patients with EPS or PDS. CONCLUSIONS & INFERENCES In EPS and PDS, delayed gastric empting and altered sensory function are disease markers but not directly linked to the severity of HRQOL impairment or clinical presentation of FD.

Abstract
Tandem mass spectrometry was used to identify naturally processed peptides bound to major histocompatibility complex (MHC) I and MHC II molecules in central nervous system (CNS) of eight patients with multiple sclerosis (MS). MHC molecules were purified from autopsy CNS material by immunoaffinity chromatography with monoclonal antibody directed against HLA-A, -B, -C, and -DR. Subsequently peptides were separated by reversed-phase HPLC and analyzed by mass spectrometry. Database searches revealed 118 amino acid sequences from self-proteins eluted from MHC I molecules and 191 from MHC II molecules, corresponding to 174 identified source proteins. These sequences define previously known and potentially novel autoantigens in MS possibly involved in disease induction and antigen spreading. Taken together, we have initiated the characterization of the CNS-expressed MHC ligandome in CNS diseases and were able to demonstrate the presentation of naturally processed myelin basic protein peptides in the brain of MS patients.

Abstract
In lung fibroblasts, proliferation is inhibited by activation of EP(2) prostanoid receptors which are known to couple to adenylyl cyclase. Beside the classic target of cAMP, protein kinase A (PKA), alternative cAMP effectors have been identified, among them Epac (exchange protein activated by cAMP). The present study aimed to illuminate transduction pathways mediating the anti-proliferative effects of EP(2) receptors in lung fibroblasts. Proliferative activity of human lung fibroblasts was determined by measuring [(3)H]-thymidine incorporation. The selective EP(2) receptor agonist butaprost inhibited [(3)H]-thymidine incorporation by 75%, an effect mimicked by forskolin, the phosphodiesterase inhibitor IBMX, the stable cAMP analogues dibutyryl-cAMP and bromo-cAMP, as well as by the Epac selective cAMP analogues 8-pCPT-2'-O-Me-cAMP and Sp-8-pCPT-2'-O-Me-cAMPS, whereas the PKA selective agonist 6-Bnz-cAMP was inactive. The PKA inhibitor Rp-8-Br-cAMPS inhibited butaprost-induced phosphorylation of CREB (cAMP response element-binding protein), but did not affect butaprost-induced inhibition of [(3)H]-thymidine incorporation. Partial knockdown of Epac1 by specific siRNA transfection resulted in a marked attenuation of the inhibitory potency of butaprost, whereas transfection of Epac2 siRNA or non-silencing siRNA did not affect the effectiveness of butaprost to inhibit [(3)H]-thymidine incorporation. In conclusion, Epac1 rather than the classic cAMP effector PKA is a crucial element in the signal transduction pathway mediating anti-proliferative effects of EP(2) receptor activation.

Abstract
Clinical observations indicate that in chronic obstructive pulmonary disease patients, the long-acting muscarinic antagonist tiotropium delays decline in airway function, suggesting that cholinergic mechanisms contribute to long-term structural changes. Human lung fibroblasts express muscarinic receptors and the present study aimed to explore their role in controlling collagen synthesis. MRC-5, HEL-299 and primary human lung fibroblasts (phLFb) were cultured. Incorporation of [(3)H]-proline into cellular proteins was determined as measure of collagen synthesis. In MRC-5 cells, the muscarinic agonist carbachol enhanced [(3)H]-proline incorporation in a concentration-dependent manner (effective concentration of 50%: 220 nM, increase at 10 microM by 40-55%, in a different series of experiments). Likewise, 10 microM oxotremorine caused an increase of approximately 65%. For comparison, transforming growth factor-beta1 (5 ng x mL(-1)) caused an increase of approximately 80%. Effects of carbachol on total [(3)H]-proline incorporation and collagenase-sensitive [(3)H]-proline fraction were similar. The effect of 10 microM carbachol was inhibited by tiotropium (inhibitory concentration of 50%: 110 pM), prevented by pertussis toxin and the mitogen-activated protein kinase inhibitor, PD 98059. Muscarinic agonists also enhanced [(3)H]-proline incorporation in a tiotropium-sensitive manner in HEL-299 cells and phLFb. In human lung fibroblasts, muscarinic receptors exert stimulatory effects on collagen synthesis. Prolonged blockade of muscarinic-induced collagen synthesis may contribute to reported beneficial long-term effects of anticholinergics in chronic obstructive pulmonary disease.

Abstract
BACKGROUND Health-related quality of life (HRQOL) is a marker of disease severity. Data on the relative impairment of HRQOL in chronic liver disease (CLD) and functional gastrointestinal disorders are lacking and no studies have assessed the link between impairment of HRQOL and psychosocial factors yet. AIM To assess predictors for, and the impairment of, HRQOL in CLD and FD. METHODS In 181 functional dyspepsia (FD) patients, 204 CLD patients and 337 healthy blood donors, HRQOL was assessed with the Short Form-36 (mental and physical component), and anxiety and depression utilizing the Hospital Anxiety and Depression Scale. RESULTS Compared with HC, HRQOL is significantly lower in FD and CLD (P-value for all <0.001). The mental but not physical component of HRQOL was significantly more impaired in FD compared with CLD (P < 0.05). After adjusting for confounders, impairment of mental (P < 0.001) and physical (P = 0.005) component of HRQOL was associated with the severity of CLD and FD. In FD, the multivariate analysis revealed depression and severity of symptoms as the most important predictors of HRQOL (R2 = 21.9 and 7.1). In CLD, the mental component of HRQOL was associated with depression and anxiety (R(2) = 9.9 and 9.7). CONCLUSIONS In tertiary care, HRQOL is more severely impaired in FD compared with CLD. Co-morbid psychiatric conditions significantly contribute to the impairment of HRQOL.

Abstract
BACKGROUND In Germany the physician staffed emergency systems have announced an increase in rescue missions over the years. The aim of this study is to analyse the development of the spectrum of patients in an emergency system over the last 20 years in order to highlight the significant changes. METHODS In a retrospective study we analyzed the prehospital chart views from 2004, 1992 and 1984 with respect to patients' demography, type of rescue mission, degree of internal disease or injury (NACA), state of consciousness (GCS), as well as prehospital interventions performed by prehospital emergency physician. RESULTS In 2004 (3,825), the absolute number of missions was 2 and 4 times higher than 1992 (2,114) and 1984 (957), resp. In all of these investigated time periods non-trauma missions (74%; 2,812 vs. 66%; 1,390 vs. 51%; 485) were leading, followed by trauma missions (18%; 690 vs. 22%; 464 vs. 39%; 375), aborted missions (3%; 126 vs. 7%; 154 vs. 6%; 56), and dead on arrival (5%; 197 vs. 5%; 106 vs. 4%; 41). Although, the percentage of patients with NACA IV-VI (39% vs. 50%) or patients with GCS < or =8 (18% vs. 34%) was lower in 2004, the absolute number of patients in each category was higher than in 1984 (NACA IV-VI: 1,434 vs. 448, p<0.01; GCS: 672 vs. 303, p<0.01). CONCLUSIONS The results of this study demonstrate, that the percentage of trauma, severely ill/injured or unconscious patients is lower than in previous years. However, the higher absolute numbers of patients demonstrate that the emergency physician now encounters more critically ill/injured, unconscious and trauma patients. It does not seem necessary to question the qualifications for an emergency physician, which have previously been considered essential for the management of acute life-threatening situations.

Abstract
BACKGROUND The mechanisms of interindividual variations in visceral pain sensitivity remain poorly understood. We characterized the neuroendocrine responses to rectal distensions in healthy individuals with high vs. low rectal pain sensitivity. METHODS Rectal sensory and pain thresholds were determined, and a series of random painful distensions was carried out. Eighteen subjects were stratified into groups with a low rectal pain threshold ("High Sensitivity" group) vs. a high rectal pain threshold ("Low Sensitivity" group) by median split, and were compared with regard to adrenocorticotropic hormone (ACTH) and cortisol, cardiovascular, and emotional responses. RESULTS Distensions led to an anticipatory stress response, reflected by elevated baseline anxiety, and increased baseline ACTH and cortisol in both groups. In response to distensions, the "Low Sensitivity" group showed significantly greater ACTH and cortisol concentrations analysis of variance (ANOVA time x group for ACTH: p<.05; for cortisol: p<.01), and elevated diastolic blood pressures (BP) (ANOVA group: p<.01) when compared to the "High Sensitivity" group. CONCLUSIONS Painful rectal distensions are associated with a pronounced anticipatory stress response, reflected by elevated anxiety and elevated stress hormones. Individuals with high rectal pain sensitivity differ from those with low pain sensitivity in distension-induced hormonal and blood pressure responses, suggesting that neuroendocrine responses may be relevant to the pathophysiology of visceral hyperalgesia.

Abstract
AIM In a prospective randomized, controlled trial, to compare the long-term outcome of intensive medical therapy (with or without cognitive-behavioural or muscle relaxation therapy) vs. standard medical therapy in patients with refractory functional dyspepsia (FD), referred to a tertiary referral medical center. METHODS A total of 100 consecutive FD patients were allocated to a standardized symptom-oriented 4 month therapy (SMT, n = 24), intensive medical therapy (IMT, medical therapy with testing-for and targeting-of abnormalities of motor-and-sensory function, n = 28) or IMT plus psychological interventions (either progressive-muscle relaxation (IMT-MR, n = 20) or cognitive-behavioural therapy (IMT-CBT, n = 28). The symptom intensity (SI) and health-related quality-of-life (HRQoL) after 12 months were prespecified primary outcome parameters. RESULTS After 12 months, significantly greater improvement of SI occurred in patients with IMT-all (with or without psychological interventions) compared with SMT (P < 0.025 vs. IMT-all). IMT, IMT-MR and IMT-CBT alone also resulted in significantly better improvement of the primary outcome parameters (P all < 0.025 vs. SMT). HRQoL significantly improved in all groups with intensive medical therapy but not standard medical therapy. Differences between intensive medical therapy-all and standard medical therapy were not significant. Concomitant anxiety and depression was improved significantly by IMT-CBT (vs. SMT) but not other treatments. CONCLUSIONS In FD patients with refractory symptoms, intensified medical management involving function testing and psychological intervention yields superior long-term-outcomes. Additional CBT may be effective for the control of concomitant anxiety and depression.

Abstract
OBJECTIVE Psychological stress has been implicated in the pathophysiology of both inflammatory and functional gastrointestinal (GI) diseases. The goal of this study was to address neuroendocrine modulation of cytokine production by peripheral blood cells in GI diseases. METHODS We analyzed the in vitro effects of the beta-adrenergic agonist terbutaline and the glucocorticoid agonist dexamethasone on TNF-alpha and IL-10 production by LPS-stimulated monocytes in whole cell blood cultures in patients with inflammatory bowel diseases in remission (N=10), diarrhoea-predominant irritable bowel syndrome (IBS, N=12), patients with a recent gastroenteritis (post-infectious group, N=10), and healthy controls (N=15). RESULTS In response to terbutaline, there was a significant increase in IL-10 production (concentration effect: p<0.05), which was diminished in IBD (group effect: p<0.01), comparable in IBS and controls, but enhanced in the post-infectious group (group x concentration effect: p<0.05). In contrast, terbutaline resulted in a concentration-dependent suppression of TNF-alpha production, which was comparable in all groups. Dexamethasone suppressed TNF-alpha production in a dose-dependent manner in all groups, but this effect was significantly more pronounced in post-infectious subjects (group effect: p<0.05). CONCLUSIONS In IBD, disturbed adrenergic regulation of IL-10 could be part of the mechanism(s) underlying the modulation of disease activity by psychological stress. Diarrhoea-predominant IBS was not associated with altered adrenergic or glucocorticoid regulation of cytokine production by peripheral blood cells, whereas a recent history of gastroenteritis was associated with disturbed neuroendocrine modulation of cytokine production, which may play role in the pathophysiology of post-infectious IBS.

Abstract
BACKGROUND Treatment satisfaction of patients with primary immunodeficiency diseases receiving hospital-based intravenous (IVIG) or home-based subcutaneous (SCIG) immunoglobulin infusions requires investigation. OBJECTIVE Evaluation of the properties and suitability of the Life Quality Index (LQI), as an instrument to assess treatment satisfaction. METHODS Patients received weekly SCIG and completed the LQI, two global treatment satisfaction questions and the CHQ-PF50 (children) or the SF-36 (adults) at baseline and 10 months. The LQI was psychometrically evaluated. RESULTS The LQI comprised four scales: treatment interference (I), therapy related problems (II), therapy setting (III), treatment costs (IV). Convergent/discriminant validity for scales I, II, III was acceptable, for scale IV moderate. CHQ-PF50 scales behavior, bodily pain, global behavior, global health, mental health, parental impact-emotion significantly correlated with LQI scale II, the family activity scale with LQI scales I, III. SF-36 scale bodily pain significantly correlated with scale III. Internal consistency was good for scales I, II, III, but poor for scale IV. Score values significantly increased for scales I, III, IV in patients switching from IVIG to SCIG. CONCLUSIONS Three valid LQI scales were determined. Cost-related questions should be removed due to low reliability. Patients-perceived therapy effectiveness and patient-physician/nurse interaction should be included in the instrument.

Abstract
BACKGROUND Our aim was to assess the relationship between gastric motor and sensory function and symptom patterns in community subjects and patients with functional dyspepsia (FD) or irritable bowel syndrome (IBS). METHODS We recruited 291 asymptomatic blood donors, 151 symptomatic blood donors (recurrent abdominal pain or discomfort), and 40 patients with FD or IBS. Abdominal symptoms were assessed using the bowel disease questionnaire (BDQ) and, in addition, the most bothersome symptom complex identified (dysmotility-type, ulcer-type dyspepsia, or IBS). Gastric emptying time (GET (t(1/2), min)) was measured by (13)C-octanoic breath test and a nutrient challenge performed. Twenty randomly selected asymptomatic blood donors, 48 symptomatic blood donors (30 FD, 18 IBS), and 40 patients (23 FD, 17 IBS) had additional function testing. RESULTS GET (t(1/2)) was significantly (p<0.05) longer in blood donors with FD symptoms (99 (6) min) and FD patients (110 (12) min) compared with asymptomatic controls (76.7 (7) min), but was not significant in IBS blood donors or patients. Overall, 25 of 48 blood donors with symptoms and 18 of 40 patients had slow gastric emptying. GET was most delayed in subjects with predominantly dysmotility-type symptoms (167 (36) min v controls; p<0.01). Symptom intensities after a nutrient challenge were significantly higher in FD patients and symptomatic blood donors compared with asymptomatic controls; 14 of 48 blood donors with symptoms and 16 of 40 patients had a symptom response to the nutrient challenge exceeding the response (mean (2SD)) of healthy asymptomatic controls. CONCLUSION Gastric emptying and the global symptom response to a standardised nutrient challenge are abnormal in population based (non-health care seeking) subjects with dyspepsia.

Abstract
BACKGROUND This study aimed to assess the efficacy of artichoke leaf extract (ALE) in the treatment of patients with functional dyspepsia (FD). METHODS In a double-blind, randomized controlled trial (RCT), 247 patients with functional dyspepsia were recruited and treated with either a commercial ALE preparation (2 x 320 mg plant extract t.d.s.) or a placebo. The primary efficacy variable was the sum score of the patient's weekly rating of the overall change in dyspeptic symptoms (four-point scale). Secondary variables were the scores of each dyspeptic symptom and the quality of life (QOL) as assessed by the Nepean Dyspepsia Index (NDI). RESULTS Two hundred and forty-seven patients were enrolled, and data from 244 patients (129 active treatment, 115 placebo) were suitable for inclusion in the statistical analysis (intention-to-treat). The overall symptom improvement over the 6 weeks of treatment was significantly greater with ALE than with the placebo (8.3 +/- 4.6, vs. 6.7 +/- 4.8, P < 0.01). Similarly, patients treated with ALE showed significantly greater improvement in the global quality-of-life scores (NDI) compared with the placebo-treated patients (- 41.1 +/- 47.6 vs. - 24.8 +/- 35.6, P < 0.01). CONCLUSION The ALE preparation tested was significantly better than the placebo in alleviating symptoms and improving the disease-specific quality of life in patients with functional dyspepsia.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most prevalent gastrointestinal disorders. The key feature of GERD is reflux of gastric contents into the esophagus. Medical treatment with proton-pump inhibitors (PPIs) is well established and is considered the standard treatment. Given the high prevalence of the condition and the excellent response to medical therapy, antireflux surgery is an option for patients with volume reflux that is not properly controlled by medical therapy. Adenocarcinoma is a rare but life-threatening complication of GERD. The only known precursor lesion for esophageal adenocarcinoma is Barrett's esophagus. In recent years, a clearer understanding of the development of Barrett's and of its progression toward invasive cancer has developed. Genetic factors almost certainly determine the individual risk. The length of the Barrett's esophagus segment and the size of a hiatal hernia are associated with the risk of developing high-grade dysplasia and esophageal adenocarcinoma.With regard to the clinical management of GERD patients with Barrett's, endoscopic surveillance at 3-year intervals is now considered appropriate in the absence of dysplasia. In patients with high-grade dyspepsia, the situation is more difficult. While a considerable proportion of these patients may already have invasive cancers, there is also the possibility that there is only focal dysplasia. For this reason, it is justifiable to carry out curative endoscopic resection. Mucosal ablation procedures may also be appropriate, but these still need to be properly investigated in clinical trials.
