It has been reported that patients with chronic heart failure exhibit an intestinal overgrowth of primary gut bacterial pathogens, such as Shigella spp., Salmonella spp., Campylobacter spp., and Yersinia enterocolitica. We failed to reproduce these findings in a cohort of 39 patients admitted to the hospital with decompensated heart failure by means of conventional stool bacterial cultures and a multiplexed polymerase chain reaction assay.

Background/Aims: Fructose malabsorption (FM) mimics symptoms of irritable bowel syndrome (IBS), and its prevalence has increased. Diagnosing FM in IBS is challenging because of its overlap with small intestinal bacterial overgrowth (SIBO). We assessed the prevalence of FM by comparing patients with IBS with asymptomatic control individuals after excluding SIBO using the glucose hydrogen breath test (HBT). Methods: Patients diagnosed with IBS and asymptomatic control individuals were prospectively enrolled in the study...

Development of the extreme form of hypothyroidism defined as myxedema is very rare. Acute symptoms and their management have been described in detail previously. However, not much attention has been devoted to therapeutic challenges that are faced in the recovery phase of the treatment, especially pertaining to the gastrointestinal system. The link between myxedema and the appearance of severe Clostridium difficile infection (CDI) has not been established so far. A 61-year-old woman with no significant medical record was admitted to hospital because of infected heel pressure and thyroid dysfunction...

Clostridial abomasitis and enteritis are important alimentary diseases observed in all domestic ruminant species. These diseases most commonly result from overgrowth of Clostridium perfringens types A, B, C, D, and E with the associated release of bacterial exotoxins that result in necrosis of the abomasal or intestinal mucosa. Clostridium difficile may also be associated with enteritis in calves but is much less common than disease caused by C perfringens. This article reviews the causes, pathophysiology, clinical signs, diagnosis, treatment, and prevention of clostridial gastrointestinal diseases in ruminants...

Since time immemorial, phages-the viral parasites of bacteria-have been protecting Earth's biosphere against bacterial overgrowth. Today, phages could help address the antibiotic resistance crisis that affects all of society. The greatest hurdle to the introduction of phage therapy in Western medicine is the lack of an appropriate legal and regulatory framework. Belgium is now implementing a pragmatic phage therapy framework that centers on the magistral preparation (compounding pharmacy in the US) of tailor-made phage medicines...

REVIEW
Stephen J D O'Keefe
This article provides evidence that current dietary fiber intake levels may be insufficient to maintain colonic mucosal health and defense, and reduce inflammation and cancer risk in otherwise healthy people. Current commercial tube feeds generally overlook the metabolic needs of the colon and may predispose patients to dysbiosis, bacterial overgrowth with pathogens such as Clostridium difficile, and acute colitis. These results raise concern about the wide-scale use of prophylactic antibiotics in the intensive care unit and the use of elemental, fiber-depleted tube feeds...

Small intestinal bacterial overgrowth (SIBO), characterized by the presence of excessive bacteria in the small intestine, is typically described as a malabsorptive syndrome occurring in the context of gut stasis syndromes. SIBO is now considered to be a disorder associated with diverse clinical conditions without classic risk factors for SIBO and a cause of several nonspecific gastrointestinal and nongastrointestinal symptoms. Because there is currently no gold standard for diagnosing SIBO, its prevalence and role in the pathogenesis of other diseases remain uncertain; as does optimal treatment of patients with relapsing symptoms...

The gut and the liver are closely linked to each other, as changes in the gut microbiota can play a significant role in the development of many liver diseases. Gut bacteria respond rapidly to changes in diet and thus can affect the liver through their metabolites. The impact of a high lipid diet on the liver in the presence of an altered gut flora modulated by ampicillin was investigated. The study was performed on 30 male Western albino rats randomly divided into 3 groups: control (phosphate buffered saline treated), group II (ampicillin 50 mg/kg for three weeks to induce microbiota alterations and fed on standard diet) and group III (same dose of ampicillin and fed on a lipid rich diet)...

Marfan syndrome is an autosomal dominant disorder involving mutation in the FBN1 gene, which encodes fibrillin-1, a protein critical to maintain the integrity of connective tissue. A mutation in this gene can affect multiple organ systems, but it is not classically associated with gastrointestinal complications. We describe a man with Marfan syndrome with multiple small bowel diverticula leading to small intestinal bacterial overgrowth and recurrent small bowel perforations.

BACKGROUND: Clostridium difficile (CD) infection (CDI) increases patient morbidity, mortality and healthcare costs. Antibiotic treatment induces gut dysbiosis and is both a major risk factor for CD colonization and treatment of CDI. Probiotics have been trialed to support commensal gut microbiota and reduce CDI. This study investigated commensal microbe Faecalibacterium prausnitzii (FP) and a prebiotic, both known to yield butyrate and be anti-inflammatory and immunomodulatory, on CD colonization and gut integrity in mice...

Bacteria residing in oral biofilms live in a state of dynamic equilibrium with one another. The intricate synergistic or antagonistic interactions between them are crucial for determining this balance. Using the 6-species Zürich "supragingival" biofilm model, this study aimed to investigate interactions regarding growth and localization of the constituent species. As control, an inoculum containing all six strains was used, whereas in each of the further five inocula one of the bacterial species was absent, and in the last both streptococci were absent...

A patient with severe postural orthostatic tachycardia syndrome (POTS) and mast cell activation syndrome (MCAS) received immunotherapy with low-dose naltrexone (LDN) and intravenous immunoglobulin (IVIg) and antibiotic therapy for small intestinal bacterial overgrowth (SIBO). A dramatic and sustained response was documented. The utility of IVIg in autoimmune neuromuscular diseases has been published, but clinical experience with POTS is relatively unknown and has not been reported in MCAS. As a short-acting mu-opioid antagonist, LDN paradoxically increases endorphins which then bind to regulatory T cells which regulate T-lymphocyte and B-lymphocyte production and this reduces cytokine and antibody production...

BACKGROUND: Gut dysbiosis associated with the use of proton-pump inhibitors (PPIs) has been found to lead to the occurrence of infectious and inflammatory adverse events. A longitudinal observational cohort study has demonstrated the heightened risk of death associated with PPI use. SUMMARY: We evaluated meta-analyses to determine the association between PPI use and infectious and inflammatory diseases. Meta-analyses showed that PPI use is a potential risk for the development of enteric infections caused by Clostridium difficile, as well as small intestinal bacterial overgrowth, spontaneous bacterial peritonitis, community-acquired pneumonia, hepatic encephalopathy, and adverse outcomes in inflammatory bowel disease...

The prone (face down) sleeping position is known to be associated with a significantly increased risk of sudden and unexpected death in infancy (sudden infant death syndrome or SIDS), however, the reasons for this are unclear. Suggested mechanisms have involved suffocation from occlusion of the external airways by soft bedding/pillows or from flattening of the nose with backward displacement of the tongue, rebreathing of carbon dioxide, blunting of arousal responses with decreased cardiac responses to auditory stimulation, diaphragmatic splinting or fatigue, lowering of vasomotor tone with tachycardia, nasopharyngeal bacterial overgrowth, overheating, alteration of sleep patterns, compromise of cerebral blood flow and upper airway obstruction from distortion of nasal cartilages...
