“…An oral anti-Clostridium whey protein from cows immunized to C. diffi cile toxoid was studied in the Netherlands. Early studies of C. diffi cile showed promise for treatment of patients with RCDI, with no further recurrences ( 128 ), but in a later study there was no signifi cant decrease in recurrences (44 % vs. 45 % ) ( 129 ). Further development of this product has been halted due to lack of funding.…”

Clostridium diffi cile infection (CDI) is a leading cause of hospital-associated gastrointestinal illness and places a high burden on our health-care system. Patients with CDI typically have extended lengths-of-stay in hospitals, and CDI is a frequent cause of large hospital outbreaks of disease. This guideline provides recommendations for the diagnosis and management of patients with CDI as well as for the prevention and control of outbreaks while supplementing previously published guidelines. New molecular diagnostic stool tests will likely replace current enzyme immunoassay tests. We suggest treatment of patients be stratifi ed depending on whether they have mild-to-moderate, severe, or complicated disease. Therapy with metronidazole remains the choice for mildto-moderate disease but may not be adequate for patients with severe or complicated disease. We propose a classifi cation of disease severity to guide therapy that is useful for clinicians. We review current treatment options for patients with recurrent CDI and recommendations for the control and prevention of outbreaks of CDI. Am J Gastroenterol 2013; 108:478-498; doi: 10.1038/ajg.2013 12. In patients in whom oral antibiotics cannot reach a segment of the colon, such as with Hartman's pouch, ileostomy, or colon diversion, vancomycin therapy delivered via enema should be added to treatments above until the patient improves. (Conditional recommendation, low-quality evidence)13. The use of anti-peristaltic agents to control diarrhea from confi rmed or suspected CDI should be limited or avoided, as they may obscure symptoms and precipitate complicated disease. Use of anti-peristaltic agents in the setting of CDI must always be accompanied by medical therapy for CDI. (Strong recommendation, low-quality evidence) Management of severe and complicated CDI14. Supportive care should be delivered to all patients and includes intravenous fl uid resuscitation, electrolyte replacement, and pharmacological venous thromboembolism prophylaxis. Furthermore, in the absence of ileus or signifi cant abdominal distention, oral or enteral feeding should be continued. 17. Vancomycin delivered orally (500 mg four times per day) and per rectum (500 mg in a volume of 500 ml four times a day) plus intravenous metronidazole (500 mg three times a day) is the treatment of choice for patients with complicated CDI with ileus or toxic colon and / or signifi cant abdominal distention. (Strong recommendation, low-quality evidence)18. Surgical consult should be obtained in all patients with complicated CDI. Surgical therapy should be considered in patients with any one of the following attributed to CDI: hypotension requiring vasopressor therapy; clinical signs of sepsis and organ dysfunction (renal and pulmonary); mental status changes; white blood cell count ≥ 50,000 cells / μ l, lactate ≥ 5 mmol / l; or failure to improve on medical therapy after 5 days. (Strong recommendation, moderate-quality evidence) Management of recurrent CDI (RCDI)19. The fi rst recurrence of CDI can be treated ...

“…Oral administration of bovine anti-C. difficile IgA in whey protein purified from immunized cow's milk (Mucomilk) (MucoVax, BV., The Netherlands) has shown efficacy with a sustained response in human primary CDI treatment and recurrence reduction [Mattila et al 2008;van Dissel et al 2005]. However, studies were not continued to include larger patient cohorts.…”

Clostridium difficile infection (CDI) is the most common infectious cause of healthcare-acquired diarrhoea. Outcomes of C. difficile colonization are varied, from asymptomatic carriage to fulminant colitis and death, due in part to the interplay between the pathogenic virulence factors of the bacterium and the counteractive immune responses of the host.Secreted toxins A and B are the major virulence factors of C. difficile and induce a profound inflammatory response by intoxicating intestinal epithelial cells causing proinflammatory cytokine release. Host cell necrosis, vascular permeability and neutrophil infiltration lead to an elevated white cell count, profuse diarrhoea and in severe cases, dehydration, hypoalbuminaemia and toxic megacolon. Other bacterial virulence factors, including surface layer proteins and flagella proteins, are detected by host cell surface signal molecules that trigger downstream cell-mediated immune pathways.Human studies have identified a role for serum and faecal immunoglobulin levels in protection from disease, but the recent development of a mouse model of CDI has enabled studies into the precise molecular interactions that trigger the immune response during infection. Key effector molecules have been identified that can drive towards a protective anti-inflammatory response or a damaging proinflammatory response.The limitations of current antimicrobial therapies for CDI have led to the development of both active and passive immunotherapies, none of which have, as yet been formally approved for CDI. However, recent advances in our understanding of the molecular basis of host immune protection against CDI may provide an exciting opportunity for novel therapeutic developments in the future.
