Evidence-Based Practice in the Treatment for Antibiotic-Associated Diarrhea in the Intensive Care Unit

Lactobacillus sp as a Probiotic for the Prevention of Clostridium difficile Associated Diarrhea

Background: Antibiotic treatment can disturb the resistance of the gastrointestinal flora to colonization. This may result in complications, the most serious of which is Clostridium difficile associated diarrhea (CDAD). The aim of this study was to determine the effectiveness of probiotics for the prevention of CDAD.Method: The databases used were Scopus, Proquest, CINAHL, Medline, Pubmed and ScienceDirect, limited to having been published in the last 5 years. A literature review followed the keyword search. The keywords used were probiotics, Clostridium difficile, associated, diarrhea, randomized, control and trial using "AND" and “OR”. Twelve trials with 5102 participants were included. Eight trials reported a preventive effect for CDAD using a mixture of 2 strains of lactobacillus, a mixture of 4 combination strains, a mixture of lactobacillus and Saccharomyces or a mixture of Bifidobacterium, Lactobacillus and Saccharomyces.Result: Our findings indicate that probiotics may prevent CDAD. Most probiotics contain a singular strain. The combination with lactobacillus sp was the most effective at preventing CDAD.Conclusion: In addition, 6 out of 8 trials had an in relation to preventing CDAD containing lactobacillus sp. Four studies said that there were some factors that meant that the probiotic could not reduce or prevent the CDAD.

Tutorial on Diarrhea and Enteral Nutrition: A Comprehensive Step-By-Step Approach

This tutorial suggests a current strategy toward a multiprofessional therapy based upon a comprehensive step-by-step approach to the course of intensive care unit diarrhea episodes. Evidence published in the last 10 years, obtained through a database search (PubMed), shows that its prevalence is quite variable. Although multicausal, it is often erroneously associated with the supply of enteral nutrition. Several complications affect not only nutrition status but also the development of skin lesions, which can become the focus of infections, and the length of hospital stay. Here, we propose an early, objective, directed, and multimodal approach, aiming at optimizing care for these patients. In a dynamic walkthrough, the reader will find a guide for the general diagnosis and for colitis resulting from Clostridium difficile infections, as well as current instructions and recommendations for drug treatment and supportive therapy for these 2 modalities. We also bring together ways to prevent and treat associated skin lesions in this setting. Because it is neglected in the critical environment, diarrhea is still a poorly addressed disease, and its complications bring about a significant worsening in quality of life and hospital stay.

Fighting AMR in the Healthcare Environment: Microbiome-Based Sanitation Approaches and Monitoring Tools

Healthcare-associated infections (HAIs) affect up to 15% of all hospitalized patients, representing a global concern. Major causes include the persistent microbial contamination of hospital environment, and the growing antimicrobial-resistance (AMR) of HAI-associated microbes. The hospital environment represents in fact a reservoir of potential pathogens, continuously spread by healthcare personnel, visiting persons and hospitalized patients. The control of contamination has been so far addressed by the use of chemical-based sanitation procedures, which however have limitations, as testified by the persistence of contamination itself and by the growing AMR of hospital microbes. Here we review the results collected by a microbial-based sanitation system, inspired by the microbiome balance principles, in obtaining more effective control of microbial contamination and AMR. Whatever the sanitation system used, an important aspect of controlling AMR and HAIs relates to the ability to check any variation of a microbial population rapidly and effectively, thus effective monitoring procedures are also described.
