Clostridium difficile infection: epidemiology, disease burden and therapy,A Clostridium difficile-fertozések epidemiológiája, betegségterhe és terápiája

Introduction:C. difficile causes 25 percent of the antibiotic associated infectious nosocomial diarrhoeas. C. difficile infection is a high-priority problem of public health in each country. The available literature of C. difficile infection’s epidemiology and disease burden is limited. Aim: Review of the epidemiology, including seasonality and the risk of recurrences, of the disease burden and of the therapy of C. difficile infection. Method: Review of the international and Hungarian literature in MEDLINE database using PubMed up to and including 20th of March, 2012. Results: The incidence of nosocomial C. difficile associated diarrhoea is 4.1/10 000 patient day. The seasonality of C. difficile infection is unproved. 20 percent of the patients have recurrence after metronidazole or vancomycin treatment, and each recurrence increases the chance of a further one. The cost of C. difficile infection is between 130 and 500 thousand HUF (430 € and 1665 €) in Hungary. Conclusions: The importance of C. difficile infection in public health and the associated disease burden are significant. The available data in Hungary are limited, further studies in epidemiology and health economics are required. Orv. Hetil., 2013, 154, 1188–1193.</jats:p

Antimicrobial therapy of Clostridium diffi cile infection: Systematic literature review and meta-analysis,A Clostridium difficile-fertozések antibiotikum- terápiája. A tudományos bizonyítékok szisztematikus áttekintése és metaanalízise

Introduction:Clostridium difficile is the leading cause of antibiotic associated infectious nosocomial diarrhoea. Limited number of new pharmaceutical products have been developed and registered in the past decades for the treatment of Clostridium difficile infection. The available scientific evidence is limited and hardly comparable. Aim: To analyse the clinical efficacy and safety of metronidazole, vancomycin and fidaxomicin in the therapy of Clostridium difficile infection. Methods: Systematic review and meta-analysis of the literature data. Results: Meta-analysis of literature data showed no significant difference between these antibiotics in clinical cure endpoint (odss ratios: fidaxomicin vs. vancomycin 1.19; vancomycin vs. metronidazol 1.69 and fidaxomicin vs. metronidazol 2.00). However, fidaxomicin therapy was significantly more effective than vancomicin and metronidazol in endpoints of recurrence and global cure (odds ratios: fidaxomicin vs. vancomycin 0.47; vancomycin vs. metronidazol 0.91 és fidaxomicin vs. metronidazol 0.43). There was no significant difference between fidaxomicin, vancomycin and metronidazole in safety endpoints. Conclusions: Each antibiotic similarly improved clinical cure. Fidaxomicin was the most effective therapeutic alternative in lowering the rate of recurrent Clostridium difficile infections. Orv. Hetil., 2013, 154, 890–899.</jats:p

Biogenesis of the insulin secretory granule in health and disease

The secretory granules of pancreatic beta cells are specialized organelles responsible for the packaging, storage and secretion of the vital hormone insulin. The insulin secretory granules also contain more than 100 other proteins including the proteases involved in proinsulin-to insulin conversion, other precursor proteins, minor co-secreted peptides, membrane proteins involved in cell trafficking and ion translocation proteins essential for regulation of the intragranular environment. The synthesis, transport and packaging of these proteins into nascent granules must be carried out in a co-ordinated manner to ensure correct functioning of the granule. The process is regulated by many circulating nutrients such as glucose and can change under different physiological states. This chapter discusses the various processes involved in insulin granule biogenesis with a focus on the granule composition in health and disease1134173
