recurrent clostridium difficile infection treated with home fecal transplantation: a case report.clostridium difficile infection causes severe diarrhea, abdominal pain and weight loss. a course of metronidazole is the initial treatment; however up to 40% of patients have at least one recurrence. some patients have recurrent infections requiring further treatment with vancomycin, others need multiple courses of expensive treatment. fecal transplantation has been proposed as an effective treatment option for patients with recurrences. we report the case of a patient with recurrent clostridium ...201425430511
right hemicolectomy in a severely anemic jehovah's witness patient with an extremely low preoperative hemoglobin level and the decision to operate.severe anemia is associated with high mortality, and patients with this condition are typically treated with packed blood red cells. patients of jehovah's witness faith, however, do not accept blood transfusion therapy. the authors report the case of a jehovah's witness patient who presented with lower gastrointestinal bleeding secondary to clostridium difficile colitis. because the patient refused blood transfusion therapy, he underwent a right hemicolectomy with a preoperative hemoglobin level ...201425429083
clostridium difficile infection: prevention, treatment, and surgical management.clostridium difficile is increasing in both incidence and severity. although metronidazole and vancomycin remain the gold standard for medical management, and surgical colectomy the gold standard for surgical management, new treatment alternatives, including the creation of a diverting loop ileostomy along with colonic lavage and vancomycin enemas, are being investigated that may lead to changes in the current treatment algorithms. the most exciting development in the treatment options for c dif ...201425440127
review of the emerging treatment of clostridium difficile infection with fecal microbiota transplantation and insights into future challenges.clostridium difficile infection (cdi) is one of the most common health care-associated infections in the united states. currently, there are no standardized methods to prepare or deliver the fecal microbiota transplantation (fmt). various methods are used to prepare the fmt, which is usually administered via nasogastric tube, colonoscopy, or by enema. several clinical trials are underway to assess the true efficacy and safety of fmt for cdi. these trials include cdi studies assessing fmt via col ...201425439277
the impact of proton pump inhibitors on the human gastrointestinal microbiome.potent gastric acid suppression using proton pump inhibitors (ppis) is common in clinical practice but may have important effects on human health that are mediated through changes in the gastrointestinal microbiome. in the esophagus, ppis change the normal bacterial milieu to decrease distal esophageal exposure to inflammatory gram-negative bacteria. in the stomach, ppis alter the abundance and location of gastric helicobacter pylori and other bacteria. in the small bowel, ppis cause polymicrobi ...201425439276
