The effects of probiotics, prebiotics and synbiotics on the reduction of IBD complications, a periodic review during 2009–2020

Aims: To perform a systematic review on randomized controlled trials to examine the efficacy of probiotics, prebiotics and synbiotics in the treatment of IBD. Methods and Results: PubMed, Web of science, Scopus and Google Scholar were systematically searched from January 2009 to January 2020 using the following keywords: ‘Inflammatory Bowel Disease’, ‘Probiotics’ and ‘Clinical trial’. The statistical analysis was performed using SPSS software version 24.0. A total of 1832 articles were found during the initial search and 21 clinical trials were eligible. Studies comparing the effects of probiotics and placebo among patients with active ulcerative colitis (UC) showed a significant difference in clinical outcomes. Moreover, probiotics improved the overall induction of remission rates among patients with Crohn’s disease (CD). Probiotics significantly decreased the IL-1β, TNF-α and IL-8 levels. Also, the need for systemic steroids, hospitalization, surgery, as well as histological score and disease activity index significantly decreased in patients who used probiotic or pro-/synbiotics. Conclusions: The use of probiotics, as food supplements, can induce anti-inflammatory reactions, balance the intestinal homeostasis and induce remission in IBD. The efficacy of probiotics on remission induction is more reported in UC rather than CD. Larger well-designed clinical trials are needed to further determine whether probiotics are of clear benefits for remission in IBD. © 2020 The Society for Applied Microbiolog

First Report on the Characteristics of Methicillin Resistant Staphylococcus Capitis Isolates and a NRCS-A-clone Related Isolate Obtained from Iranian Children

BACKGROUND: Methicillin-resistant Staphylococcus capitis (MRSC) NRCS-A clone (Multi-resistant and vancomycin-non susceptible) has been recently described as an emerging cause of nosocomial bacteremia especially in neonatal intensive-care units (NICUs). OBJECTIVE: The objective of this study was to evaluate the antibiotic and antiseptic resistance patterns, biofilm producing ability and the prevalence of SCCmec and ACME types among MRSC isolates as well as to check the possible presence of NRCS-A clone at Tehran's Children's Medical Center, Iran. METHODS: A total of 256 coagulase negative Staphylococcal isolates were collected, of which 10 S. capitis isolates were obtained and tested for susceptibility against 13 antimicrobial and 3 antiseptic agents, as well as biofilm production. The presence of 15 distinct resistance genes, staphylococcal cassette chromosome mec (SCCmec), and arginine catabolic mobile elements (ACMEs) were tracked. RESULTS: Seven out of 10 S. capitis isolates were MRSC (MIC90 van=8mug/mL) and resistant to trimethoprim/sulfamethoxazole, produced biofilm, (3 as strong biofilm producers) and carried ACME types I and II. Despite the identification of mec and ccr complexes in some isolates, all the SCCmec cassettes were untypeable (UT). CONCLUSION: According to the studied features, only one isolate belonged to the NRSC-A clone. The results indicate that MRSC with high antibiotic resistance and unknown SCCmec might become a serious problem in the future for the treatment of patients particularly children

The effects of probiotics on reducing the colorectal cancer surgery complications: A periodic review during 2007�2017

Background & aims: To assess the effects of pro-/synbiotic treatment on patients with colorectal cancer (CRC), a systematic review was conducted on randomized controlled trials. Methods: International databanks (ISI Web of Science, PubMed, Scopus, and Google Scholar) were searched from January 2007 to December 2017 using the following keywords: �colorectal cancer� and �probiotics�. The search was restricted to original articles published in English. Reference lists of all related studies were also reviewed to find other relevant publications. The statistical analysis was performed using SPSS software version 18.0 (IBM, NY, USA). Also, p < .05 was regarded as statistically significant. Results: A total of 21 clinical trials were retrieved, involving 1831 patients subjected to elective colorectal surgery. The studies included in this review have investigated the effects of probiotics on different aspects of colorectal cancer treatment (p < .05). According to the present study results, probiotics could significantly decrease inflammatory factors, chemotherapy side effects, severe diarrhea, postoperative infectious complications, and duration of antibiotic therapy; shift fecal microbiota in favor of Actinobacteria; and change the tumor tissue microbiota (p < .05). Conclusion: Based on the present review, the preoperative use of pro-/synbiotics as prophylaxis for patients with CRC could improve clinical outcomes. More detailed data about the types of probiotic species and the optimal consumption dose of pro-/synbiotics should be taken in to account in future meta-analysis reviews. © 2019 Elsevier Ltd and European Society for Clinical Nutrition and Metabolis
