Atypical Acute Neuroborreliosis With Leg Paresis and Constipation.

BACKGROUND/AIM: An 80-year-old male patient had complained of proximal paresis of the left leg, pain and sensory disturbances in the left abdomen, exanthema in the left lower abdomen, coprostasis, and severe abdominal pain, as well as a progressive deterioration of his general condition for weeks. The patient had already presented to three other medical centers. Colonoscopy and computed tomography of the abdomen could not explain the pronounced symptomatology. In addition, there was acute elevator paresis of the left leg and severe pruritic rash on both sides of the trunk. CASE REPORT: At the Israelitisches Krankenhaus Hamburg (IKH), laboratory parameters of urine, stool, and blood, ultrasound, electrocardiogram, and transthoracic echocardiography diagnosis showed no abnormalities. Esophago-gastro-duodenoscopy revealed patchy erythema and moderately severe chronic low-activity Helicobacter-positive gastritis. Colonoscopically, two polyps were ablated. A neurological examination with magnetic resonance imaging and electroneurography also showed normal findings. Evidence of autoimmune or rheumatoid disease was also absent. Finally, analysis of the cerebrospinal fluid revealed a lympho-granulocytic cell count (32/3 lymphocytes, 21/3 granulocytes) and an elevated Borrelia-specific IgG index (Ai) of 20.82. This finding was confirmed by a complementary serological diagnosis, in which Borrelia-specific IgM and IgG antibodies were detected. In sum, Bannwart's syndrome was assumed to be the cause of the neurological symptoms. The 21-day borreliosis therapy included doxycycline administration and analgesia with novaminsulfone and pregabalin as needed. CONCLUSION: A complex symptomatology of leg paresis, lower abdominal pain and sensory disturbances, exanthema, and coprostasis in combination with a long-lasting poor general condition were found to be the consequences of atypical neuroborreliosis.

[The new guideline on irritable bowel syndrome: what is new?] / Die neue Leitlinie zum Reizdarmsyndrom: Was ändert sich?

IRRITABLE BOWEL SYNDROME: WHAT IS NEW?: The following refers only to irritable bowel syndrome (IBS) in adults. The new guideline includes a separate section on IBS for paediatric patients. Irritable bowel syndrome (IBS) presents as a heterogeneous picture with chronic abdominal complaints related to the bowel. These are usually accompanied by changes in bowel movements and lead to impaired quality of life. The genesis is multifactorial and there are complex underlying pathophysiological mechanisms associated with IBS. Thus, disturbances in various components of the gut-brain axis and the increasing importance of the microbiome can be identified. Various psychological comorbidities also play a role. DIAGNOSTICS: The diagnosis is made by a thorough anamnesis and symptom-oriented exclusion of important differential diagnoses. A subdivision into different subtypes depending on the main symptoms is beneficial for the further management of IBS patients. The diagnosis of IBS should be made as early as possible after reliable exclusion of the important differential diagnoses. If diarrhoea dominates as a symptom, a detailed differential diagnosis and functional diagnosis should be carried out. THERAPY: There is no proven causal and no established standard therapy. Due to the variable genesis and symptom manifestation of IBS, a broad spectrum of therapy options results, whereby there is no individual prediction regarding effectiveness and therefore every therapy is initially probationary. Symptom-independent general therapies that can be used for all subtypes include dietary methods (e. g. the low-FODMAP diet), probiotics, psychotherapy methods and complementary medicine. The choice of symptom-dependent drug treatments is made according to the subtype/main symptom. In the case of diarrhoea, bile acid binders, the non-absorbable antibiotic rifaximin or, in individual cases, 5-HT3-antagonists can be used in addition to loperamide. In constipation, prucalopride and linaclotide have value in addition to the use of soluble fibre and macrogol/other laxatives. For abdominal pain/cramps, studies show good results for spasmolytics, especially peppermint oil, and for tricyclic-type antidepressants. For the main symptom of flatulence, probiotics, rifaximin and especially the low-FODMAP diet can show positive results in studies.

Heat-inactivated Bifidobacterium bifidum MIMBb75 (SYN-HI-001) in the treatment of irritable bowel syndrome: a multicentre, randomised, double-blind, placebo-controlled clinical trial.

BACKGROUND: Bifidobacterium bifidum MIMBb75 is one of a few probiotic strains that have been shown to be effective in the treatment of irritable bowel syndrome (IBS) and its symptoms. Non-viable strains might have advantages over viable bacteria for product stability and standardisation, as well as for tolerability because safety concerns have been raised for specific patient groups who are susceptible to infection. We aimed to assess the efficacy of non-viable, heat-inactivated (HI) B bifidum MIMBb75 (SYN-HI-001) in the treatment of IBS and its symptoms. METHODS: We did a double-blind, placebo-controlled trial in which patients with IBS were recruited from 20 study sites in Germany and randomly assigned to receive either two placebo capsules or two capsules with a combined total of 1 × 109 non-viable B bifidum HI-MIMBb75 cells to be taken orally once a day for 8 weeks. Eligible patients were diagnosed with IBS according to Rome III criteria and had abdominal pain (≥4 on an 11-point numerical rating scale) on at least 2 days during a 2-week run-in phase. Patients with chronic inflammatory bowel diseases, systemic diseases, cancer, autoimmune diseases, with an intake of antipsychotic medications 3 months before study start, or with an intake of systemic corticosteroids within 1 month before study start were excluded. Randomisation was in a 1:1 ratio according to a computer-generated blocked list. Patients, investigators, clinical monitors, project managers, and statisticians were masked to the randomisation. The primary composite endpoint was the combination of at least 30% improvement of abdominal pain and adequate relief of overall IBS symptoms being fulfilled in at least 4 of 8 weeks during treatment. Analysis of the primary endpoint included all randomly assigned patients receiving at least one dose of study medication and who had no severe protocol violation. Safety analysis included all patients who had taken at least one dose of the study medication and was based on frequency and severity of adverse events, laboratory evaluation, and global assessment of tolerability. This trial is registered with the ISRCTN registry, ISRCTN14066467, and is completed: the results shown here represent the final analysis. FINDINGS: Patients were screened between April 15, 2016, and Feb 3, 2017, and 443 patients were allocated to the placebo group (n=222) or the B bifidum HI-MIMBb75 group (n=221). The composite primary endpoint was reached by 74 (34%) of 221 patients in the B bifidum HI-MIMBb75 group compared with 43 (19%) of 222 in the placebo group (risk ratio 1·7, 95% CI 1·3-2·4; p=0·0007). No serious adverse events occurred in the B bifidum HI-MIMBb75 group; seven adverse events suspected to be related to the study product were reported in the B bifidum HI-MIMBb75 group as were eight in the placebo group. No deaths were reported in this study. The most common reported adverse event with a suspected relationship to the study product was abdominal pain, which was reported in two (<1%) patients in the B bifidum HI-MIMBb75 group and one (<1%) in the placebo group. Tolerability was rated as very good or good by 200 (91%) patients in the B bifidum HI-MIMBb75 group compared with 191 (86%) in the placebo group. INTERPRETATION: This study shows that B bifidum HI-MIMBb75 substantially alleviates IBS and its symptoms in a real-life setting. These results indicate that specific beneficial bacterial effects are mediated independently of cell viability. FUNDING: Synformulas.

Pancreatic Exocrine Insufficiency as a Complication of Gastrointestinal Surgery and the Impact of Pancreatic Enzyme Replacement Therapy.

BACKGROUND: Pancreatic exocrine insufficiency (PEI) is characterized by inadequate production, insufficient secretion, and/or inactivation of pancreatic enzymes, resulting in maldigestion. The aim of this review was to analyze the prevalence and pathophysiology of PEI resulting from gastrointestinal (GI) surgery and to examine the use of pancreatic enzyme replacement therapy (PERT) for effectively managing PEI. SUMMARY: A targeted PubMed search was conducted for studies examining the prevalence and pathophysiology of PEI in patients following GI surgery and for studies assessing the effects of PERT in these patients. PEI is a common complication following GI surgery that can lead to nutritional deficiencies, which may contribute to morbidity and mortality in patients. Timely treatment of PEI with PERT can prevent malnutrition, increase quality of life, and possibly reduce the associated mortality. Treatment of PEI should aim not only to alleviate symptoms but also to achieve significant improvements in nutritional parameters. Dose optimization of PERT is required for effective management of PEI, in addition to regular assessment of nutritional status, appropriate patient education, and reassessment if symptoms return. Key Messages: Difficulties in detecting PEI following GI surgery can result in undiagnosed and untreated maldigestion, leading to metabolic complications and increased morbidity. Both are preventable by early administration and monitoring for optimal doses of PERT.

European society of neurogastroenterology and motility guidelines on functional constipation in adults.

INTRODUCTION: Chronic constipation is a common disorder with a reported prevalence ranging from 3% to 27% in the general population. Several management strategies, including diagnostic tests, empiric treatments, and specific treatments, have been developed. Our aim was to develop European guidelines for the clinical management of constipation. DESIGN: After a thorough review of the literature by experts in relevant fields, including gastroenterologists, surgeons, general practitioners, radiologists, and experts in gastrointestinal motility testing from various European countries, a Delphi consensus process was used to produce statements and practical algorithms for the management of chronic constipation. KEY RESULTS: Seventy-three final statements were agreed upon after the Delphi process. The level of evidence for most statements was low or very low. A high level of evidence was agreed only for anorectal manometry as a comprehensive evaluation of anorectal function and for treatment with osmotic laxatives, especially polyethylene glycol, the prokinetic drug prucalopride, secretagogues, such as linaclotide and lubiprostone and PAMORAs for the treatment of opioid-induced constipation. However, the level of agreement between the authors was good for most statements (80% or more of the authors). The greatest disagreement was related to the surgical management of constipation. CONCLUSIONS AND INFERENCES: European guidelines on chronic constipation, with recommendations and algorithms, were developed by experts. Despite the high level of agreement between the different experts, the level of scientific evidence for most recommendations was low, highlighting the need for future research to increase the evidence and improve treatment outcomes in these patients.

The Prevalence, Comorbidity, Management and Costs of Irritable Bowel Syndrome.

BACKGROUND: Insufficient data are available on the administrative incidence and prevalence of irritable bowel syndrome (IBS) in Germany, as well as on its comorbidities, diagnostic evaluation, treatment, and costs. METHODS: We analyzed routine data from a statutory health insurance carrier with approximately eight million insurees. IBS was identified from the ICD-10 codes K58.0, K58.9, and F45.32 (outpatient care by a physician, outpatient and inpatient care in a hospital). The cumulative incidence for the year 2017 was determined by the exclusion of insurees who had carried the diagnosis of IBS in any of the preceding 12 years. The frequencies of comorbid diseases and of diagnostic and therapeutic measures were compared with those of persons in age- and sex- matched control groups without IBS. RESULTS: In 2017, the administrative incidence of IBS was 0.36%, and its prevalence was 1.34%. Persons with IBS were often documented as having other gastrointes- tinal diseases, headache, back pain, and mental disorders. There was evidence for the insufficient use of ultrasound and colonoscopy and for the excessive use of computed tomography and magnetic resonance imaging for diagnostic evaluation. The costs of medical care for insurees with IBS in the year of their initial diagnosis were higher than those of other insurees without the diagnosis of IBD (€ 3770 vs. € 2788) and rose in each of the eight years preceding the initial diagnosis. CONCLUSION: Patients with IBS in Germany are likely not receiving sufficient diag- nostic evaluation in conformity with the relevant guidelines. The high prevalence of comorbid mental disorders and other pain syndromes implies that the complaints of patients with IBS need to be more comprehensively evaluated and treated.

[Microbiome And Gastrointestinal Diseases]. / Mikrobiom und gastrointestinale Erkrankungen.

For some years, microbiome research has become a thriving topic. The most diverse and hitherto poorly understood connections of interactions of the microbiome with the host body (human) seem to play an important role in the genesis of a wide variety of diseases. This article focuses on the importance of the microbiome in gastrointestinal diseases and presents therapeutic approaches.The intestinal microbiome will not be understood completely for a long time due to the highly complex relationships and variety of different microorganisms. The intestinal microbiome is critically involved in the development of diseases, especially in the development of inflammatory bowel disease. Helicobacter pylori infection is a major risk factor for gastric carcinoma. Esophageal microbiome alterations can cause inflammation and decrease the tone of the lower esophageal sphincter. Inflammation is a crucial pathway for tumorigenesis, it can be caused by the "normal" flora and by pathogenic agents. In the microbiome of the colon, interactions of bacteria, viruses and fungi have a very special status. Good oral/dental status protects against pancreatic carcinoma. Fecal microbiome transfer has become more important in the American guideline. Understanding the processes in the intestinal microbiome provides approaches to new therapies that are likely to exceed our current imagination.

Contribution of pancreatic enzyme replacement therapy to survival and quality of life in patients with pancreatic exocrine insufficiency.

The objective of this study was to analyze the current evidence for the use of pancreatic enzyme replacement therapy (PERT) in affecting survival and quality of life in patients with pancreatic exocrine insufficiency (PEI). Systematic searches of the literature were performed using the PubMed database. Articles were selected for inclusion if they reported findings from trials assessing the effects of PERT on quality of life, survival, malabsorption, growth parameters (such as height, body weight and body mass index), or gastrointestinal symptoms (such as abdominal pain, stool consistency and flatulence). PERT improved PEI-related malabsorption and weight maintenance in patients with cystic fibrosis, chronic pancreatitis, pancreatic cancer, and post-surgical states. In patients with chronic pancreatitis, PERT improved PEI-related symptoms and quality of life measures. Several small retrospective studies have also suggested that PERT may have a positive impact on survival, but long-term studies assessing this effect were not identified. PERT is effective for treating malnutrition and supporting weight maintenance, and it is associated with improved quality of life and possibly with enhanced survival in patients with PEI. However, there is evidence that not all patients with PEI receive adequate PERT. Future work should aim to assess the long-term effects of PERT on the survival of patients with PEI.

Economic burden of moderate to severe irritable bowel syndrome with constipation in six European countries.

BACKGROUND: Irritable bowel syndrome with predominant constipation (IBS-C) is a complex disorder with gastrointestinal and nervous system components. The study aim was to assess the economic burden of moderate to severe IBS-C in six European countries (France, Germany, Italy, Spain, Sweden and the UK). METHODS: An observational, one year retrospective-prospective (6 months each) study of patients diagnosed in the last five years with IBS-C (Rome III criteria) and moderate to severe disease at inclusion (IBS Symptom Severity Scale score ≥ 175). The primary objective was to assess the direct cost to European healthcare systems. RESULTS: Five hundred twenty-five patients were included, 60% (range: 43.1-78.8%) suffered from severe IBS-C. During follow-up 11.1-24.0% of patients had a hospitalisation/emergency room (ER) visit, median stay range: 1.5-12.0 days and 41.1-90.4% took prescription drugs for IBS-C. 21.4-50.8% of employed patients took sick leave (mean: 11.6-64.1 days). The mean annual direct cost to the healthcare systems was €937.1- €2108.0. The total direct cost (combined costs to healthcare systems and patient) for IBS-C was €1421.7-€2487.1. CONCLUSIONS: IBS-C is not a life-threatening condition; however, it has large impact on healthcare systems and society. Direct and indirect costs for moderate to severe IBS-C were high with the largest direct cost driver being hospitalisations/ER visits.

Multi-omic based molecular profiling of advanced cancer identifies treatable targets and improves survival in individual patients.

A proof-of-concept study was conducted to assess whether patients with advanced stage IV cancer for whom predominantly no standard therapy was available could benefit from comprehensive molecular profiling of their tumor tissue to provide targeted therapy. Tumor samples of 83 patients were collected under highly standardized conditions and analyzed using immunohistochemistry, next-generation sequencing and phosphoprotein profiling. Expression and phosphorylation of key oncogenic pathways were measured to identify targets at the (phospho-) proteomic level. At genomic level, 50 oncogenes and tumor suppressor genes were analyzed. Based on molecular profiling, targeted therapies were decided by the attending oncologist. Accordingly, 28 patients who met the defined criteria fell in two equal-sized groups. One group received targeted therapies while the other did not. Following six months of treatment, disease control was achieved by 49% of patients receiving targeted therapy (complete remission, 14%; partial remission, 21%; stable disease, 14%; disease progression, 36%; death, 14%) and 21% of patients receiving non-targeted therapy (stable disease, 21%; disease progression, 64%; death, 14%). Individual patients experienced dramatic responses to a therapy which otherwise would not have been applied. This approach clarifies the value of multi-omic molecular profiling for cancer diagnostics.

Medical Therapy of Constipation: Current Standards and Beyond.

Chronic constipation is a very common medical problem with relevant impact on the patients' quality of life. Modern definitions recognize constipation as a polysymptomatic disorder, including various aspects of disturbed defecation. Current guidelines recommend a stepwise approach in the management of chronic constipation. Isolated or concomitant evacuation disorders should be identified and may need differential/additional treatment. Baseline measures include lifestyle components and bulking agents. The next step recommends treatment with conventional laxatives. In refractory patients, modern medical therapies, such as the prokinetic prucalopride or the secretagogues linalotide or lubiprostone, may be used effectively. For patients with opioid-induced constipation, the modern concept of peripherally acting µ-opioid antagonists has shown to successfully improve this increasing medical problem and even to potentially increase survival time in terminally ill patients on opioid therapy. Prolonged-released oral naloxone (in fixed combination with oxycodone), oral naloxegol or naldemedine, and subcutaneous methylnaltrexone have all demonstrated good efficacy and tolerability in the treatment of opioid-induced constipation. To adequately apply stepwise treatment algorithms, a simple tool to identify treatment failure may improve patient care.

Efficacy and tolerability of linaclotide in the treatment of irritable bowel syndrome with constipation in a real­world setting - results from a German noninterventional study.

BACKGROUND: Linaclotide is a minimally absorbed peptide guanylate cyclase-C agonist approved for the treatment of irritable bowel syndrome with constipation (IBS-C). This study assessed the efficacy and tolerability of linaclotide in IBS-C in routine clinical practice in Germany. METHODS: This was a 52-week, noninterventional study of linaclotide in patients aged ≥ 18 years with moderate to severe IBS-C. Severity of abdominal pain and bloating and frequency of bowel movements were assessed over 5 study visits. Treatment-related adverse events were recorded. RESULTS: The study enrolled 375 patients; the mean observation duration was 4.4 months. Linaclotide marketing was halted during the study period for economic reasons, accounting for low patient numbers and short observation duration. Linaclotide significantly reduced mean (standard deviation [SD]) scores between treatment start (visit 1) and study end (visit 5) for abdominal pain intensity (visit 1: 4.87 [2.63] vs. visit 5: 2.40 [2.20], p < 0.0001), mean [SD] bloating intensity (visit 1: 5.30 [2.70] vs. visit 5: 2.86 [2.34], p < 0.0001), and increased mean [SD] bowel movement frequency (visit 1: 2.71 [1.80] vs. 4.38 [1.86], p < 0.0001). Diarrhea, occurring in 5.1 % of patients, was the most common adverse event. CONCLUSION: Linaclotide is effective in improving the major symptoms of IBS-C and demonstrates a favorable safety profile in the real-world environment of routine clinical practice.

Expert consensus document: Advances in the diagnosis and classification of gastric and intestinal motility disorders.

Disturbances of gastric, intestinal and colonic motor and sensory functions affect a large proportion of the population worldwide, impair quality of life and cause considerable health-care costs. Assessment of gastrointestinal motility in these patients can serve to establish diagnosis and to guide therapy. Major advances in diagnostic techniques during the past 5-10 years have led to this update about indications for and selection and performance of currently available tests. As symptoms have poor concordance with gastrointestinal motor dysfunction, clinical motility testing is indicated in patients in whom there is no evidence of causative mucosal or structural diseases such as inflammatory or malignant disease. Transit tests using radiopaque markers, scintigraphy, breath tests and wireless motility capsules are noninvasive. Other tests of gastrointestinal contractility or sensation usually require intubation, typically represent second-line investigations limited to patients with severe symptoms and are performed at only specialized centres. This Consensus Statement details recommended tests as well as useful clinical alternatives for investigation of gastric, small bowel and colonic motility. The article provides recommendations on how to classify gastrointestinal motor disorders on the basis of test results and describes how test results guide treatment decisions.
