[Recurrence of Clostridium difficile-associated diarrhoea prevented by the administration of a whey concentrate from specifically immunised cows; prospective study].

Objective: To try to prevent recurrences of Clostridium difficile-associated diarrhoea (CDAD) by treatment with a specific neutralising secretory IgA-enriched whey-protein concentrate (40%) made from the milk of cows immunised with C. difficile and its toxins.

Design: Prospective, non-blinded, clinical cohort study.

Community-onset Clostridium difficile-associated diarrhoea not associated with antibiotic usage--two case reports with review of the changing epidemiology of Clostridium difficile-associated diarrhoea.

The emergence of hypervirulent strains of Clostridium difficile causing outbreaks in hospitals and nursing homes may result in a greater than before spread of the bacterium in the community. By consequence, the incidence of community-onset cases of Clostridium difficile-associated diarrhoea (CDAD) may increase outside known risk groups that are currently characterised by prior hospitalisation, prior antibiotic usage, older age and significant comorbidity. Here, we describe two case histories of community-onset CDAD.

Psoriasis is not associated with IL-12p70/IL-12p40 production and IL12B promoter polymorphism.

Psoriasis is a type-1 T cell-mediated, chronic inflammatory disease. Since interleukin (IL)-12p70 promotes the development of type-1 T cells, we investigated whether psoriasis is associated with an increased production of this cyctokine by blood cells. Results revealed that the production of IL-12p70 by cells of psoriasis patients stimulated by 1 and 10 ng per mL, but not 100 ng per mL of lipopolysaccharide (LPS) was higher (p=0.
