REVIEW
Vitória H M Mottin, Edna S Suyenaga
Acne and Atopic Dermatitis (AD) are chronic inflammatory skin conditions with severe impact on a patient's life. Current treatments are related to adverse effects and do not represent a definitive cure. The present paper reviews the alterations in skin microbiome, specifically in acne and AD, and aims in searching for potential treatments based on benefic microorganisms, called probiotics. The review was made through bibliographic search of the main databases (Science Direct, PubMed, Scielo, Medline) between September 2015 and June 2016...

OBJECTIVE: In recent years, a great number of studies have been directed toward the evaluation of gastrointestinal microbiota modulation through the introduction of beneficial microorganisms, also known as probiotics. Many studies have highlighted how this category of bacteria is very important for the good development, functioning, and maintenance of our immune system. There is a delicate balance between the immune system, located under the gut epithelial barrier, and the microbiota, but many factors can induce a disequilibrium that leads to an inflammatory state and dysbiosis...

Obesity is a risk factor for osteoarthritis (OA), the greatest cause of disability in the US. The impact of obesity on OA is driven by systemic inflammation, and increased systemic inflammation is now understood to be caused by gut microbiome dysbiosis. Oligofructose, a nondigestible prebiotic fiber, can restore a lean gut microbial community profile in the context of obesity, suggesting a potentially novel approach to treat the OA of obesity. Here, we report that - compared with the lean murine gut - obesity is associated with loss of beneficial Bifidobacteria, while key proinflammatory species gain in abundance...

The gut-liver axis plays a pivotal role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD), which is the third cause of hepatocellular carcinoma (HCC) worldwide. However, the link between gut microbiota and hepatocarcinogenesis remains to be clarified. The aim of this study is to explore what features of the gut microbiota are associated with HCC in cirrhotic patients with NAFLD. A consecutive series of patients with NAFLD-related cirrhosis and HCC (group 1: 21 patients), NAFLD-related cirrhosis without HCC (group 2: 20 patients) and healthy controls (group 3: 20 patients) was studied for gut microbiota profile, intestinal permeability, inflammatory status and circulating mononuclear cells...

Transfer of antibiotic resistance genes from probiotic bacteria to pathogens poses a safety concern. Orally administered probiotics are exposed to stressful conditions during gastrointestinal transit. In this study, filter mating experiments were performed to investigate the potential role of exposure of Bifidobacterium isolates to acid and bile stress on the transfer of a tetracycline resistance gene, tet (W), to Enterococcus faecalis ATCC 51299. No E. faecalis transconjugants were obtained after mating with either stressed or unstressed Bifidobacterium , thereby suggesting that tet (W) could not be transferred as a result of exposure to gastrointestinal stresses...

Natural killer (NK) cells are an important component of the immune response to influenza infection, but are subject to alteration during aging, which may play a role in impaired response to infection and vaccination in older people. Enhancement of NK cell activity could, therefore, present a means to improve the immune response to vaccination in older subjects, and pre- and probiotics offer an opportunity to modulate antiviral defenses via alteration of the gut microbiota. This study investigated the effect of a novel probiotic, Bifidobacterium longum bv...

This study was conducted to evaluate the protective efficacy of dietary Bacillus coagulans (B. coagulans) supplementation in birds receiving Salmonella enteritidis (SE). Two hundred and forty 1-day-old Cobb broilers were randomly assigned to 2 × 2 factorial arrangements of treatments with 2 levels of dietary B. coagulans (0 or 400 mg/kg) and 2 levels of SE challenge (0 or 1 × 109 SE between d 9 to 11). Results showed that SE infection did not affect growth performance, but caused intestinal inflammation and barrier function impairment by reducing intestinal goblet cells and beneficial bacteria numbers, increasing cecal Salmonella colonization and liver Salmonella invasion, downregulating jejunal mucin-2 (at 7 and 17 d post-infection, DPI), TLR2 (at 7 and 17 DPI), TLR4 (at 17 DPI), TNFSF15 (at 7 and 17 DPI) gene mRNA levels, and upregulating jejunal IFN-γ mRNA levels (at 17 DPI) compared to uninfected birds...

BACKGROUND: Imbalance of the human gut microbiota in childhood, mainly due to low gut biodiversity and a low bifidobacterial load, has been suggested as a risk factor for atopy. Administration of Enterococcus faecium L3 in infants has been shown to increase the gut bifidobacterial count. The aim was to verify if a mixture of Bifidobacterium animalis subsp. lactis BB12 and E. faecium L3 could reduce the signs, symptoms and need for drugs in atopic children. METHODS: We retrospectively analyzed, and compared with controls, clinical outcomes following use of BB12 and L3 strains when administered 3 months before or during the development of signs and symptoms of atopy...
