Helicobacter Pylori (H. pylori) is a Gram-negative flagellated microorganism that has been extensively studied since its first isolation due to its widespread diffusion and association with numerous diseases. While the bacterium is proved to be a causative factor for a number of gastric diseases such as gastritis, gastric adenocarcinoma, and MALT-lymphoma, its role at other gastrointestinal levels and in other systems is being thoroughly studied. In this article, we reviewed the latest published clinical and laboratory studies that investigated associations of H. pylori with hematologic diseases such as Vitamin B12- and iron-deficiency anemia, primary immune thrombocytopenia, and with a number of dermatologic and ophthalmic diseases. In addition, the putative role of the bacterium in inflammatory bowel diseases, esophageal disorders, metabolic, diseases, neurologic diseases and allergy were outlined.

BackgroundBismuth quadruple (BQT) and non‐bismuth quadruple (N‐BQT) therapies are the recommended first‐line treatments for Helicobacter (H.) pylori infection.ObjectiveTo compare the efficacy of BQT and N‐BQT in clinical practice in an area with high clarithromycin resistance, choosing the regimen on the basis of previous exposure to clarithromycin.MethodsA total of 404 consecutive H pylori‐positive, naïve patients were enrolled. A total of 203 patients without previous exposure to clarithromycin received N‐BQT, 100 patients for 10 days and 103 for 14 days, whereas 201 with previous exposure to clarithromycin received 10‐day BQT. Efficacy and treatment‐related adverse events were assessed.Results and ConclusionsEradication rates by intention‐to‐treat analysis were 88.2% for N‐BQT and 91.5% for BQT (P = .26); per‐protocol analysis eradication rates were 91.2% and 95.8% for N‐BQT and BQT, respectively (P = .07). Eradication rates were significantly higher with 14‐day than 10‐day CT (P < .003). Almost all patients had a good compliance with both N‐BQT (95.6%) and BQT (95%). Adverse events occurred in 24.1% and 26.9% (P = .53) of patients in the N‐BQT and BQT group, respectively. In conclusion, clarithromycin‐containing non‐bismuth or bismuth quadruple therapy, based on the knowledge of previous clarithromycin exposure, is effective and safe even in an area of high prevalence of clarithromycin‐resistant H pylori strains.

Introduction Normal sexual activity is an important determinant of quality of life. Unfortunately, several chronic health disorders are associated with an impaired sexual function. Objective To provide coverage of the current literature on prevalence and pathophysiology of sexual dysfunction in patients with gastrointestinal and liver disorders Methods A Comprehensive review of the literature on the prevalence of sexual dysfunction in chronic gastrointestinal and liver disorders, assessing the underlying mechanism (s) was performed. Results Many gastrointestinal disorders, either functional or organic, are associated with some degree of sexual dysfunction. The main pathogenic mechanisms are: (i) the disease itself causing fatigue, anxiety or depression with a potential alteration of self-esteem; (ii) worry of transmitting a potential infectious agent through sexual activity; (iii) alteration of the endocrine mechanisms which are necessary for normal sexual functioning; (iv) chronic pro- inflammatory conditions which may cause endothelial dysfunction and abnormal vascular responses; (v) iatrogenic. Conclusion Based on this review, a thorough evaluation of sexual function through validated questionnaires and/or psychological interviews with patients with chronic gastrointestinal disorders should be part of the clinical assessment in order to timely diagnose and possibly treat sexual dysfunction in this clinical setting.

: Inflammatory bowel diseases (IBD) are chronic multifactorial diseases characterized by partially unclear pathogenic mechanisms including changes in intestinal microbiota. Despite the microbiota alteration is well established in IBD patients, as reported by 16RNA sequencing analysis, an important goal is to define if it is just a consequence of the disease progression or a trigger factor of the disease itself. To date gut microbiota composition and gut microbiota-related metabolites seem to affect the host healthy state both by modulating metabolic pathways or acting on the expression of different genes through epigenetic effects. Because of this, it has been suggested that intestinal microbiota might represent a promising therapeutic target for IBD patients. The aim of this review is to summarize both the most recent acquisitions in the field of gut microbiota and its involvement in intestinal inflammation together with the available strategies for the modulation of microbiota, such as prebiotics and/or probiotics administration or fecal microbiota transplantation.

Background and Aims:The optimal management of naïve and not naïve Helicobacter pylori patients remains unclear. Therefore, it is essential to evaluate whether the actual clinical practice mirrors the indications suggested by the guidelines.
