OBJECTIVE/BACKGROUND: Clostridium difficile infection (CDI) is a potential complication during hematopoietic stem cell transplantation (HSCT), and no specific recommendations exist regarding treatment of CDI in allogeneic SCT patients. Use of metronidazole and oral vancomycin has been associated with clinical failure. Fidaxomicin has previously been found noninferior to the use of oral vancomycin for the treatment of CDI, and no studies have compared the use of oral vancomycin with fidaxomicin for the treatment of CDI in allogeneic SCT...

Drug release from a new type of matrix material consisting of partially fibrillated microcrystalline cellulose was investigated. A mechanical treatment of novel AaltoCell™ cellulose microcrystals caused partial opening of the nanofibrillary structure of the cellulose particles and entanglement of individual particles led into formation of an elastic network of microcrystalline cellulose. The rheological properties of the stable hydrogel-like materials were characterised by shear rheometry. Model compounds metronidazole and lysozyme were successfully employed in drug release experiments carried out by delignified (bleached) and lignin-containing matrices...

Necrotizing fasciitis (NF) is a devastating disease that typically affects immunocompromised patients, chronically debilitated patients or drug users, but can also affect healthy patients. Necrotizing fasciitis can rapidly produce septic shock and requires immediate surgical management of the necrotic tissue. It is a bacterial infection that progresses rapidly and has a high mortality generally caused by aerobic and anaerobic bacteria. The patient was immunocompromised and drug user. During treatment, a combination of broad-spectrum antibiotic therapy with Ciprofloxacin and Metronidazole, besides the use of activated charcoal dressing composed of carbonized fabric and impregnated with 0...

A seven day pretreatment course of an oral antibiotic cocktail (Ampicillin, Metronidazole, Neomycin Sulfate, and Vancomycin) was shown to induce changes in peripheral immune regulation and protect mice from signs of experimental autoimmune encephalomyelitis (EAE). To determine if a shorter course of antibiotic pretreatment could also protect the mice from EAE and induce regulatory immune cells, studies were conducted using the same oral antibiotic cocktail for three days. In addition, the CNS was examined to determine the effects of antibiotic pretreatment on EAE disease course and immune modulation within the affected tissue...

Obesity and diabetes in humans are associated with increased rates of anxiety and depression. To understand the role of the gut microbiome and brain insulin resistance in these disorders, we evaluated behaviors and insulin action in brain of mice with diet-induced obesity (DIO) with and without antibiotic treatment. We find that DIO mice have behaviors reflective of increased anxiety and depression. This is associated with decreased insulin signaling and increased inflammation in in the nucleus accumbens and amygdala...
