Abstract
Malabsorption is a complex and multifaceted condition characterised by the defective passage of nutrients into the blood and lymphatic streams. Several congenital or acquired disorders may cause either selective or global malabsorption in both children and adults, such as cystic fibrosis, exocrine pancreatic insufficiency (EPI), coeliac disease (CD) and other enteropathies, lactase deficiency, small intestinal bacterial overgrowth (SIBO), autoimmune atrophic gastritis, Crohn's disease, and gastric or small bowel resections. Early recognition of malabsorption is key for tailoring a proper diagnostic work-up for identifying the cause of malabsorption. Patient's medical and pharmacological history are essential for identifying risk factors. Several examinations like endoscopy with small intestinal biopsies, non-invasive functional tests, and radiologic imaging are useful in diagnosing malabsorption. Due to its high prevalence, CD should always be looked for in case of malabsorption with no other obvious explanations and in high-risk individuals. Nutritional support is key in management of patients with malabsorption; different options are available, including oral supplements, enteral or parenteral nutrition. In patients with short bowel syndrome, teduglutide proved effective in reducing the need for parenteral nutrition, thus improving the quality of life of these patients. Primary care physicians have a central role in early detection of malabsorption and should be involved into multidisciplinary teams for improving the overall management of these patients. In this European consensus, involving 10 scientific societies and several experts, we have dissected all the issues around malabsorption, including the definitions and diagnostic testing (Part 1), high-risk categories and special populations, nutritional assessment and management, and primary care perspective (Part 2).

Abstract
BACKGROUND Although proton pump inhibitor (PPI) drugs have considered able to induce small intestinal bacterial overgrowth (SIBO), no data are so far available from primary care (PC). We assessed the prevalence of SIBO and methane (CH4) production consequent to chronic PPI therapy using Lactulose Breath Test (LBT). Secondary aim was to explore the possible role of rifaximin in treating PPI-induced SIBO patients. METHODS One hundred twenty-five gastroesophageal reflux disease patients, constantly treated with PPI for at least 6 months and undergoing to LBT, were retrospectively assessed. An age-matched control population (control) of 100 patients, which had not used PPI in the last 6 months, was also enrolled. In the PPI group, SIBO positive patients and CH4 producers were treated with rifaximin 1200 mg/daily for 14 days and re-checked with LBT one month after the end of treatment. The area under the curve (AUC) before and after treatment was also calculated for both SIBO positive patients and CH4 producers. RESULTS In the PPI group, SIBO prevalence was significantly higher vs. controls (38/125 [30.4%] vs. 27/100 [27%], P<0.05). 77/125 (61.6%) PPI patients were found to be CH4 producers vs. 21/100 (21%) controls (P<0.05). Among SIBO patients in the PPI group, 34 (89.4%) were also CH4 producers vs. 17/27 (63%) controls (P<0.05). After treatment, LBT resulted negative in 15/22 SIBO patients (68.1%) (P<0.05) and in 18/34 CH4 producers (52.9%) (P<0.05). At the AUC analysis, an overall reduction of 54.2% for H2 in SIBO patients and of 47.7% for CH4 was assessed after rifaximin treatment (P<0.05). CONCLUSIONS Our data showed that chronic use of PPI could be able to increase the prevalence of SIBO and to shift the intestinal microbial composition towards a CH4-producing flora. rifaximin could represent a useful therapeutical option for PPI-induced SIBO and for modulating CH4-producing flora.

Abstract
AbstractThe spectrum of gastrointestinal (GI) issues in the older population varies from common physiological age-related changes to devastating, less common sinister pathological illness. GI system has direct exposure to external environment. Thus, it is modeled to embrace the pathophysiological changes that occur due to interaction with external factors. Gastrointestinal tract (GIT) per se is more resilient to aging as compared to other organ systems. On the other hand, elderly may present with a large plethora of GI symptoms. This presents a challenge to all echelons of medical consultation for accurate attribution for the aging process or pathophysiological causation of GI symptoms. This dichotomy leads to hindrance in adequate and appropriate treatment of GI ailments. In GI system, non-neoplastic disorders are far more common than neoplastic disorders. Hence, it becomes imperative to understand the aging evolution of the GI system and management of GI disorders in the older population.

Abstract
Diarrhea is one of the most commonly reported adverse effect of hemotherapy and targeted cancer therapies, such as tyrosine kinase inhibitors (TKI), which often significantly impact patient quality of life, morbidity, and mortality. Neratinib is an oral, irreversible pan-HER tyrosine kinase inhibitor, which is clinically active in HER2-positive breast cancer. Diarrhea is the most common side effect of this potent anticancer drug and the reasons for this adverse effect are still largely unclear. We have recently shown that activation of the calcium-sensing Receptor (CaSR) can inhibit secretagogue-induced diarrhea in the colon, therefore we hypothesized that CaSR activation may also mitigate neratinib-induced diarrhea. Using an established ex vivo model of isolated intestinal segments, we investigated neratinib-induced fluid secretion and the ability of CaSR activation to abate the secretion. In our study, individual segments of the rat intestine (proximal, middle, distal small intestine, and colon) were procured and perfused intraluminally with various concentrations of neratinib (10, 50, 100 nmol L-1). In a second set of comparison experiments, intraluminal calcium concentration was modulated (from 1.0 to 5.0 or 7.0 mmol L-1), both pre- and during neratinib exposure. In a separate series of experiments R-568, a known calcimimetic was used CaSR activation and effect was compared to elevated Ca2+ concentration (5.0 and 7.0 mmol L-1). As a result, CaSR activation with elevated Ca2+ concentration (5.0 and 7.0 mmol L-1) or R-568 markedly reduced neratinib-induced fluid secretion in a dose-dependent manner. Pre-exposure to elevated luminal calcium solutions (5.0 and 7.0 mmol L-1) also prevented neratinib-induced fluid secretion. In conclusion, exposure to luminal neratinib resulted in a pronounced elevation in fluid secretion in the rat intestine. Increasing luminal calcium inhibits the neratinib-associated fluid secretion in a dose-dependent manner. These results suggest that CaSR activation may be a potent therapeutic target to reduce chemotherapy-associated diarrhea.

Abstract
Background/Aims To evaluate changes in gut microbiota composition following long-term proton pump inhibitor (PPI) treatment. Methods Twenty-four-week-old F344 rats were fed diets with (n=6) or without (n=5) lansoprazole for 50 weeks. Profiles of luminal microbiota in the terminal ileum were then analyzed. Pyrosequencing of the 16S rRNA gene was performed using an FLX genome sequencer (454 Life Sciences/Roche). Results Rats treated with lansoprazole showed significantly reduced body weights compared to controls (lansoprazole-treated rats and controls, 322.3±15.3 g vs 403.2±5.2 g, respectively, p<0.001). However, stool frequencies and consistencies did not differ between the two groups. The composition of the gut microbiota in lansoprazole-treated rats was quite different from that of the controls. In the controls, the microbiota profiles obtained from the terminal ileum showed a predominance of Proteobacteria (93.9%) due to the abundance of Escherichia and Pasteurella genera. Conversely, lansoprazole-treated rats showed an elevated population of Firmicutes (66.9%), which was attributed to an increased ratio of Clostridium g4 to Lactobacillus genera. Conclusions This preliminary study suggests that long-term administration of PPI may cause weight loss and changes to the microbiota in the terminal ileum.

Abstract
BACKGROUND & AIMS Use of proton pump inhibitors (PPIs) could predispose individuals to small intestinal bacterial overgrowth (SIBO) by altering the intraluminal environment and bacterial flora. There is controversy regarding the risk of SIBO among PPI users because of conflicting results from prior studies. A systematic review and meta-analysis were performed to evaluate the association between PPI use and SIBO, using objective clinical outcome measures. METHODS Clinical studies comparing SIBO risk among adult users of PPIs vs nonusers were identified in MEDLINE/PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and the National Institutes of Health Clinical Trials databases through July 2012. Two reviewers independently extracted data on study characteristics and outcomes. The primary metameter was the odds ratio (OR) of SIBO among PPI users vs nonusers. Subgroup analyses were performed to examine the influence of study characteristics, such as SIBO diagnostic modality, on study outcome. RESULTS Eleven studies (n = 3134) met inclusion criteria. The pooled OR of SIBO in PPI users vs nonusers was 2.282 (95% confidence interval [CI], 1.238-4.205). No significant single large study or temporal effect was seen. Subgroup analysis revealed an association between SIBO and PPI use in studies that used duodenal or jejunal aspirate cultures to diagnose SIBO (OR, 7.587; 95% CI, 1.805-31.894), but no relationship was found between SIBO and PPI use in studies that used the glucose hydrogen breath test (OR, 1.93; 95% CI, 0.69-5.42). Funnel plot analysis identified 4 outlying studies, indicating the possible presence of publication bias. CONCLUSIONS PPI use statistically was associated with SIBO risk, but only when the diagnosis was made by a highly accurate test (duodenal or jejunal aspirate culture). Differences in study results could arise from the use of different tests to diagnose SIBO.

Abstract
The topic of gastroenterology (GI) in the elderly has been extensively reviewed. It takes special skill, patience and insight to interview the elderly, as well as to appreciate their altered physiology and interpretation of their presenting symptoms and signs, often against an extreme background of complex medical problems. The maldigestion and malabsorption coupled with altered motility contributes to the development of malnutrition. There generally a decrease of function of the GI tract, but there may be loss of adaptability in response to changes in diet or nutritional stress. Pathological alterations which might lead to minor overall intestinal functional variations in the young because of a normal process of adaptation, may lead to much more serious events in the elderly.

Abstract
Small intestinal bacterial overgrowth (SIBO) syndrome is characterized in its florid form by diarrhoea and weight loss. The most common underlying factors are dysmotility, small intestinal obstruction, blind or afferent loops. Small intestinal bacterial overgrowth can be diagnosed by: 1) culture of jejunum aspirate for bacterial counts, 2) 14C-D-xylose breath testing, 3) non-invasive hydrogen breath testing using glucose or lactulose or 4) 14C-glycocholic acid breath testing. The treatment usually consists of the eradication of bacterial overgrowth with repeated course of antimicrobials, correction of associated nutritional deficiencies and, when possible, correction of the underlying predisposing conditions.

Abstract
Irritable bowel syndrome (IBS) may result from a dysfunctional interaction between the indigenous flora and the intestinal mucosa, which in turn leads to immune activation in the colonic mucosa. Some propose that bacterial overgrowth is a common causative factor in the pathogenesis of symptoms in IBS; others point to evidence suggesting that the cause stems from more subtle qualitative changes in the colonic flora. Bacterial overgrowth will probably prove not to be a major factor in what will eventually be defined as IBS. Nevertheless, short-term therapy with either antibiotics or probiotics seems to reduce symptoms among IBS patients. However, in the long term, safety issues will favor the probiotic approach; results of long-term studies with these agents are eagerly awaited.

Abstract
BACKGROUND/OBJECTIVES In older people, small bowel bacterial overgrowth syndrome may be a common, but under-diagnosed, cause of diarrhoea and nutrient malabsorption. We aim to determine which clinical features and baseline laboratory investigations indicate a high likelihood of small bowel bacterial overgrowth as defined by a positive glucose breath test. METHODS A retrospective analysis of records for all patients referred for glucose breath test over a 6-year period to a teaching hospital. RESULTS Out of 197 referrals, 168 patient records were located and analysed (62 male, 106 female; median age 65). Patient characteristics predictive of a positive glucose breath test were: increasing age (p < 0.01), low serum vitamin B12 (p = 0.02), low serum albumin (p = 0.03), previous partial gastrectomy (p < 0.01), previous right hemi-colectomy (p < 0.01), presence of small bowel diverticulae (p = 0.01) and concurrent use of a proton pump inhibitor (p < 0.01). 52.5% (n = 21/40) of patients studied who were over 75 years old versus 21.8% (n = 28/128) of those under 75 years old had a positive glucose breath test (p < 0.01). The median time to diagnosis, from first hospital visit to positive glucose breath test, was 39 weeks. CONCLUSIONS There is often a significant delay in diagnosis of small bowel bacterial overgrowth. We suggest that this diagnosis should be considered earlier in the investigative algorithm in older patients with indicative symptoms and a predisposing factor (including previous partial gastrectomy, previous right hemi-colectomy, small bowel diverticulae or use of a proton pump inhibitor) or concurring laboratory indices (low vitamin B12 or albumin).

Abstract
The observation that the intestinal Na(+)-glucose cotransporter remains intact in most diarrheal illnesses led to development of the life-saving, low-cost technology of oral rehydration salt (ORS) solutions. The primary therapeutic role of ORS solutions is in prevention and treatment of dehydration during management of acute gastroenteritis. Successful oral rehydration therapy involves early use of ORS with maintenance or timely resumption of regular feeding. Since the inception of the oral rehydration approach more than three decades ago, the widespread use of ORS solutions has revolutionized the management and outcomes of acute gastroenteritis in children and adults. The efficacy of the World Health Organization ORS solution and of commercial ORS formulations has been enhanced by reducing osmolarity. Newer formulations of ORS are under active investigation, with promise of added benefits, including promotion of intestinal healing. This article reviews fluid and electrolyte transport in the gastrointestinal tract, the pathophysiologic mechanisms of acute diarrhea, and the basis and formulation of current and newer ORS solutions. Guidelines for efficacious use of ORS in the management of acute gastroenteritis and short gut syndrome are also provided.

Abstract
OBJECTIVES Late-onset Crohn's disease (CD) may show a distinctive pattern of expression. The aim of our study was to describe the incidence or presentation of CD in the elderly and compare the outcomes in patients < 60 years or > or = 60 years at diagnosis. METHODS The study included a population based inception cohort of all incident CD cases diagnosed in Brittany (France) between 1994 and 1997. Sixty-three patients were > or = 60 years and 201 were < 60 years at diagnosis. The physicians managing the patients used standardized questionnaires to collect the study data. The questionnaires on outcomes and treatments were completed in 2002. RESULTS In patients > or = 60 years, the annual incidence was 2.5 per 10 persons and clinical features were similar to those in younger patients, except for a higher rate of colon involvement. Among older patients, those with diverticula (29/63, 46%) were more likely to have granulomas (58% vs 33% of patients without diverticula, P < 0.04), but the diagnosis of CD was confirmed by lesions remote from the diverticula in most cases (23/29). Early resection rates were not higher in older patients, who were less likely to require immunosuppressants or re-admission for CD flares, as compared to younger patients. Five year mortality in older patients was 16% but was unrelated to CD. CONCLUSIONS In Brittany, the age specific incidence, clinical features, and prognosis of CD among the elderly are comparable to those in younger individuals. Colon involvement is more common. Concomitant diverticular disease is common and should prompt a search for CD lesions at other sites to confirm the diagnosis. Older patients are less likely to require immunosuppressants or admission for flares.

Abstract
Small bowel bacterial overgrowth (SBBO) syndrome is associated with excessive numbers of bacteria in the proximal small intestine. The pathology of this condition involves competition between the bacteria and the human host for ingested nutrients. This competition leads to intraluminal bacterial catabolism of nutrients, often with production of toxic metabolites and injury to the enterocyte. A complex array of clinical symptoms ensues, resulting in chronic diarrhea, steatorrhea, macrocytic anemia, weight loss, and less commonly, protein-losing enteropathy. Therapy is targeted at correction of underlying small bowel abnormalities that predispose to SBBO and appropriate antibiotic therapy. The symptoms and signs of SBBO can be reversed with this approach.
