Characterization of Circulating Clostridium difficile Strains, Host Response and Intestinal Microbiome in Hospitalized Children With Diarrhea

Conclusions: Children with diarrhea regularly carried toxigenic and non-toxigenic strains of C. difficile, demonstrating enhanced microbiotal diversity, and change in milieu, without apparent morbidity. This unexpected finding is contrary to that seen in adults with C. difficile disease.

AbstractIn acute gastroenteritis (AGE), identification of the infectious agent is important for patient management. Since symptoms do not reliably identify the agent, microbiological diagnostics are important. Conventional methods lack sensitivity and often take days. Multiplex PCR panels offer fast and sensitive alternatives. Our aim was to assess the performance of the new QIAstat Gastrointestinal Panel (GIP) detecting 24 different gastroenteric pathogens from stool in Cary-Blair transport medium (Adenovirus F 40/41, Astrovirus, Norovirus GI/GII, Rotavirus A, Sapovirus,Campylobacter spp.,Clostridium difficile,Plesiomonas...

ConclusionsLocal GXP testing compared to centralized multiplex PCR testing for IF, NV and CD, demonstrated sensitivities, specificities and NPV between 95% and 100%. Turnaround times were faster, enabling quicker infection prevention and control decision making. In our local setting (WCUH), the GXP demonstrated the potential to reduce NV and IFA/B outbreaks.

Clostridioides (Clostridium) difficile infection (CDI) is the most common causative pathogen of health care-associated gastrointestinal infections; however, due to the overlap of clinical symptoms with those of other causes of acute gastroenteritis, the selection of the most appropriate laboratory test is difficult. From April to October 2018, 640 stool samples requested for CDI testing were examined using the mariPOC CDI and Gastro test (ArcDia), which allows the detection of C. difficile glutamate dehydrogenase (GDH) and toxin A/B, norovirus genogroups GI and GII.4, rotavirus, adenovirus, and Campylobacter spp. In parall...

ConclusionXpert SA Nasal Complete for MRSA detection, Xpert C. difficile, and Xpert Norovirus can be used as POCT solely by HCWs in a ward setting. Each assay was used throughout a seven-day/24 h period with potential positive impact on bed management and patient care.

CONCLUSIONS: Current literature show similar risks for bacterial pathogens. Studies are limited for viral and parasitic pathogens. The evaluated risk-factors for PI-IBS varied among the included studies and the existing evidence is insufficient to identify pathogen-specific risk factors.

(University of Toronto - Leslie Dan Faculty of Pharmacy) Healthcare-associated infections are the fourth leading cause of death in Canada, predicted to move up to second place by 2050. Scientists at the Leslie Dan Faculty of Pharmacy, University of Toronto received $1.5 million in funding from Genome Canada to develop a new nanoparticle sensor technology that will allow hospitals and long-term care facilities to rapidly detect and visually identify highly infectious pathogens including C. difficile, methicillin-resistant S aureus (MRSA), Norovirus and influenza.

Conclusion: In our experience using the PCR- Biofire assay we show that this approach is feasible and can be used safely to tailor therapy in immunocompromised patients. In all cases, E.Coli was found, most frequently STEC (Shiga-like toxin producing E. coli). Using this approach enable us to identify new pathogens causing diarrhea in immunocompromised patients, extremely quickly. These preliminary results reveal the need for more clinical experience using the Biofire FilmArray as a diagnostic test for patients with MM and other haematological malignancies, who present acutely with severe diarrhea.DisclosuresTadmor: NOVART...
