Fecal microbial transplant

Jin Ah Cho, Daniel J F Chinnapen
Mucosal surfaces that line our gastrointestinal tract are continuously exposed to trillions of bacteria that form a symbiotic relationship and impact host health and disease. It is only beginning to be understood that the cross-talk between the host and microbiome involve dynamic changes in commensal bacterial population, secretion, and absorption of metabolites between the host and microbiome. As emerging evidence implicates dysbiosis of gut microbiota in the pathology and progression of various diseases such as inflammatory bowel disease, obesity, and allergy, conventional treatments that either overlook the microbiome in the mechanism of action, or eliminate vast populations of microbes via wide-spectrum antibiotics need to be reconsidered...

Parkinson's disease (PD) patients display alterations in gut microbiota composition. However, mechanism between gut microbial dysbiosis and pathogenesis of PD remains unexplored, and no recognized therapies are available to halt or slow progression of PD. Here we identified that gut microbiota from PD mice induced motor impairment and striatal neurotransmitter decrease on normal mice. Sequencing of 16S rRNA revealed that phylum Firmicutes and order Clostridiales decreased, while phylum Proteobacteria, order Turicibacterales and Enterobacteriales increased in fecal samples of PD mice, along with increased fecal short-chain fatty acids (SCFAs)...

In this prospective cohort study, we examine the feasibility of a protocol to optimize microbiota for fecal microbiota transplantation (FMT). Donor stool metrics generally accepted as markers of gut health were used to select a stool donor based on superior microbial diversity, balanced constitution of Bacteroidetes versus Firmicutes and high concentration of fecal butyrate. Selected donor microbiota was then administered via FMT. A total of 10 patients with median age of 12 years with recurrent Clostridium difficile infection (rCDI) received the intervention...

BACKGROUND: Conditions of excess androgen in women, such as polycystic ovary syndrome (PCOS), often exhibit intergenerational transmission. One way in which the risk for PCOS may be increased in daughters of affected women is through exposure to elevated androgens in utero. Hyperandrogenemic conditions have serious health consequences, including increased risk for hypertension and cardiovascular disease. Recently, gut dysbiosis has been found to induce hypertension in rats, such that blood pressure can be normalized through fecal microbial transplant...

PURPOSE OF REVIEW: Maintaining gut barrier defenses, modulating immune responses, and supporting the role of commensal microbiota are major factors influencing outcome in critical illness. Of these, maintaining a commensal 'lifestyle' and preventing the emergence of a virulent pathobiome may be most important in reducing risk of infection and multiple organ failure. RECENT FINDINGS: The polymeric formulas utilized for enteral nutrition in the ICU are absorbed high in the gastrointestinal tract and may not reach the microbial burden in the cecum where their effect is most needed...

Necrotizing enterocolitis (NEC) is a catastrophic disease caused by a variety of factors in neonates, especially preterm infants. Severe NEC has a high fatality rate, and most survivors may face short- and long-term adverse prognosis. Risk factors for NEC include preterm birth, non-breastfeeding, microbial abnormalities in the digestive tract, and ischemia-reperfusion injury. High-resolution abdominal ultrasound helps with the early diagnosis of NEC. The preventive measures for NEC include protecting the intestinal mucosa through nutritional intervention, interfering with intestinal injury signals, changing intestinal microflora, and performing early minimal enteral nutrition...

Chronic functional constipation is a kind of common intestinal disease that occurs in children, adults and elderly people. This disease not only causes great influence to physiological function, but also results in varying degrees of psychological barriers. At present, constipation treatments continue to rely on traditional methods such as purgative therapy and surgery. However, these approaches can disrupt intestinal function. Recent research between intestinal diseases and gut microbiota has gradually revealed a connection between constipation and intestinal flora disturbance, providing a theoretical basis for microbial treatment in chronic constipation...

Obesity is a major public health issue as it is causally associated with several chronic disorders, including type-2 diabetes, cerebrovascular disease (CVD), and cancer. In the United States and other countries worldwide, the obesity epidemic has drastically impacted the status of health of millions as well as healthcare costs. Aside from poor diet, hygiene, and genetics, there are many other factors thought to play an important role in the emergence of obesity. Nowadays, accumulating evidence is elucidating the relation of dysbiosis of intestinal bacteria with obesity and metabolic disorders...

Inflammation and infection are key promoters of colon cancer but the molecular interplay between these events is largely unknown. Mice deficient in leukotriene B4 receptor1 (BLT1) are protected in inflammatory disease models of arthritis, asthma and atherosclerosis. In this study, we show that BLT1-/- mice when bred onto a spontaneous tumor (ApcMin/+ ) model displayed an increase in the rate of intestinal tumor development and mortality. A paradoxical increase in inflammation in the tumors from the BLT1- / - ApcMin/+ mice is coincidental with defective host response to infection...

The intestinal microbiota comprise an important organ that plays a vital role in host digestion, development, energy maintenance, hemostasis, and immunity. Disruption of the gut microbial community due to diet, lifestyle, or antibiotic exposure increases susceptibility to chronic infection and disease. Fecal microbiota transplantation (FMT) involves the transfer of gut microbiota from a healthy donor to a patient in order to restore normal diversity and function of the microbial community. This method has become a well established alternative therapy for the treatment of recurrent Clostridium difficile infection...

Antibiotics are the cornerstone to cure infectious diseases, however, it also destroys the intestinal inherent microflora, and may cause serious gastrointestinal dysfunction, such as abdominal distension, diarrhea, mucosal barrier damage etc. In severe conditions, it may induce intestinal sepsis. With the development of the human microbiology group program and the popularity of microbial sequencing technology, people can comprehend the effects of antibiotics on intestinal flora deeply, meanwhile the traditional biomedical model (the basis of bacterial disease) is questioned...

Fecal microbiota transplantation (FMT), also known as fecal bacteriotherapy or fecal infusion, consists of injection of a liquid filtrate of feces from a healthy donor into the gastrointestinal tract of a recipient individual. FMT has been proposed as a therapeutic approach for functional diseases of the gastrointestinal tract by reestablishment of a wide diversity of intestinal flora. Clostridium difficile infection (CDI) treatment guideline from American Gastroenterology Association (AGA) recommends that FMT can be used as the treatment protocols of relapse CDI...

Chickens of good and poor feed efficiency (FE) have been shown to differ in their intestinal microbiota composition. This study investigated differences in the fecal bacterial community of good and poor feed efficient chickens at 16 and 29 days post-hatch (dph) and evaluated whether a fecal microbiota transplant (FMT) from feed efficient donors early in life can affect the fecal microbiota in chickens at 16 and 29 dph, chicken's FE and nutrient retention at four weeks of age. One-hundred-ten chickens were inoculated with a FMT or a control transplant (CT) on 1, 6 and 9 dph and ranked according to residual feed intake (RFI; metric for FE) on 30 dph...

The intestinal microbial ecosystem is actively regulated by Paneth cell-derived antimicrobial peptides such as α-defensins. Various disorders, including graft-versus-host disease (GVHD), disrupt Paneth cell functions, resulting in unfavorably altered intestinal microbiota (dysbiosis), which further accelerates the underlying diseases. Current strategies to restore the gut ecosystem are bacteriotherapy such as fecal microbiota transplantation and probiotics, and no physiological approach has been developed so far...

The intestinal microbiota is a plastic ecosystem that is shaped by environmental and genetic factors, interacting with virtually all tissues of the host. Many signals result from the interplay between the microbiota with its mammalian symbiont that can lead to altered metabolism. Disruptions in the microbial composition are associated with a number of comorbidities linked to the metabolic syndrome. Promoting the niche expansion of beneficial bacteria through diet and supplements can improve metabolic disorders...

INTRODUCTION: The intestinal microbial composition appears to differ between healthy controls and individuals with Type 2 diabetes (T2D). This observation has led to the hypothesis that perturbations of the intestinal microbiota may contribute to the development of T2D. Manipulations of the intestinal microbiota may therefore provide a novel approach in the prevention and treatment of T2D. Indeed, fecal transplants have shown promising results in both animal models for obesity and T2D and in human clinical trials...
