Abstract
BACKGROUND Severe acute pancreatitis is a potentially life-threatening disease. Despite being a common disorder, acute pancreatitis lacks a specific treatment. The present study aimed to examine the effects of probiotics on pancreatic inflammation and intestinal integrity in mice with acute pancreatitis. METHODS Male ICR mice were randomly divided into 4 groups (n = 6 per group). The control group received two intraperitoneal (i.p.) injections of normal saline as a vehicle control. The acute pancreatitis (AP) group received two i.p. injections of L-arginine 450 mg/100 g body weight. AP plus probiotics groups received L-arginine to induce acute pancreatitis as above. In the single-strain and mixed-strain groups, mice received 1 mL of Lactobacillus plantarum B7 1 × 108 CFU/mL and 1 mL of Lactobacillus rhamnosus L34 1 × 108 CFU/mL and Lactobacillus paracasei B13 1 × 108 CFU/mL by oral gavage, respectively for 6 days starting 3 days prior to the AP induction. All mice were sacrificed 72 h after L-arginine injection. Pancreatic tissue was obtained for histological evaluation and immunohistochemical studies for myeloperoxidase, whereas ileal tissue was used for immunohistochemical studies for occludin, and claudin-1. Blood samples were collected for amylase analysis. RESULTS Serum amylase levels and pancreatic myeloperoxidase levels in the AP group were significantly higher than in controls and significantly decreased in probiotic groups compared with the AP group. Ileal occludin and claudin-1 levels were significantly lower in the AP group than in controls. Ileal occludin levels significantly increased, whereas ileal claudin-1 levels did not significantly change in both probiotic groups as compared with the AP group. The pancreatic histopathology showed significantly higher degree of inflammation, edema, and fat necrosis in the AP group, and these changes improved in mixed-strained probiotic groups. CONCLUSIONS Probiotics, particularly the mixed-strain ones, attenuated AP via the reduction of inflammation and the maintenance of intestinal integrity.

Abstract
Antibiotics do not differentiate between good and bad germs, disrupting normal microflora and causing vitamin deficiency in the human body. They also kill healthy bacteria in the gut and genital tract on a large scale, weakening the host's defense mechanism. Probiotics are a colony of bacteria that live in our intestines and are regarded as a metabolic 'organ' due to their beneficial effects on human health, including metabolism and immunological function. They are used in clinical settings to prevent and treat conditions such as diarrhoea, colon cancer, hypertension, diabetes, acute pancreatitis, Helicobacter pylori infection, ventilator-associated pneumonia, migraine and autism. Probiotics may modify immunological activity by increasing innate and adaptive immune responses, altering microbial habitat in the intestine, improving gut barrier function, competitive adherence to the mucosa and epithelium, and producing antimicrobial compounds. The aim of this study is to index that further in depth researches to be conducted on probiotics pivotal role in the prophylaxis and therapeutic usage for a variety of disease that may or may not have treatment alternatives. Key words such as probiotics, microbiota, prophylactics, and therapeutic applications were searched extensively in research databases such as PubMed, PubMed Central (PMC), Scopus, Web of Science, Research Gate, Google Scholar, and Cochrane Library. This concise narrative review article summarized primarily the history, selection, mechanism/mode of action, recent advances in prophylactic and therapeutic applications, and future directions in the use of probiotics for prophylactic and therapeutic applications.

Abstract
Intestinal barrier dysfunction plays a critical role in the pathophysiology of many diseases including severe acute pancreatitis (SAP). Interleukin-22 (IL-22) is a critical regulator of intestinal epithelial homeostasis. However, the mechanism, origin site, and characteristics of IL-22 in the intestinal barrier dysfunction remains elusive. Studies were conducted in patients with SAP and SAP mice model. SAP mice model was induced by intraductal infusion of 5% taurocholic acid. The level and source of IL-22 were analyzed by flow cytometry. The effect of IL-22 in SAP-associated intestinal injury were examined through knockout of IL-22 (IL-22-/- ) or administration of recombinant IL-22 (rIL-22). IL-22 increased in the early phase of SAP but declined more quickly than that of proinflammatory cytokines, such as IL-6 and TNF-α. CD177+ neutrophils contributed to IL-22 expression in SAP. IL-22 was activated in the colon rather than the small intestine during SAP. Deletion of IL-22 worse the severity of colonic injury, whereas administration of rIL-22 reduced colonic injury. Mechanistically, IL-22 ameliorates the intestinal barrier dysfunction in SAP through decreasing colonic mucosal permeability, upregulation of E-cadherin and ZO-1 expression, activation of pSTAT3/Reg3 pathway and restoration of fecal microbiota abundance. This study revealing that early decreased colonic IL-22 aggravates intestinal mucosal barrier dysfunction and microbiota dysbiosis in SAP. Colonic IL-22 is likely a promising treating target in the early phase of SAP management. Research in context Evidence before this study Intestinal barrier dysfunction plays a critical role in the pathophysiology of severe acute pancreatitis (SAP). Interleukin-22 (IL-22) is a critical regulator of intestinal epithelial homeostasis. However, the mechanism, origin site and characteristics of IL-22 in the intestinal barrier dysfunction remains elusive. Added value of this study Firstly, we determined the dynamic expression profile of IL-22 in SAP and found that IL-22 was mostly activated in the pancreas and colon and decreased earlier than proinflammatory cytokines. CD177+ neutrophils contributed to IL-22 expression in SAP. Furthermore, we found that IL-22 ameliorates intestinal barrier dysfunction in SAP through decreasing colonic mucosal permeability, upregulation of E-cadherin and ZO-1 expression, activation of pSTAT3/Reg3 pathway and restoration of fecal microbiota abundance. Implications of all the available evidence This study highlights the role of colonic injury and colonic IL-22 in SAP. IL-22 is likely a promising treating target in the early phase of SAP management.

Abstract
Pancreatic-related disorders such as pancreatitis, pancreatic cancer, and type 1 diabetes mellitus (T1DM) impose a substantial challenge to human health and wellbeing. Even though our understanding of the initiation and progression of pancreatic diseases has broadened over time, no effective therapeutics is yet available for these disorders. Mounting evidence suggests that gut dysbiosis is closely related to human health and disease, and pancreatic diseases are no exception. Now much effort is under way to explore the correlation and eventually potential causation between the gut microbiome and the course of pancreatic diseases, as well as to develop novel preventive and/or therapeutic strategies of targeted microbiome modulation by probiotics, prebiotics, synbiotics, postbiotics, and fecal microbiota transplantation (FMT) for these multifactorial disorders. Attempts to dissect the intestinal microbial landscape and its metabolic profile might enable deep insight into a holistic picture of these complex conditions. This article aims to review the subtle yet intimate nexus loop between the gut microbiome and pancreatic diseases, with a particular focus on current evidence supporting the feasibility of preventing and controlling pancreatic diseases via microbiome-based therapeutics and therapies.

Abstract
The gut microbiota is a critical element in the balance between human health and disease. Its impairment, defined as dysbiosis, is associated with gastroenterological and systemic diseases. Pancreatic secretions are involved in the composition and changes of the gut microbiota, and the gut microbiota may colonize the pancreatic parenchyma and be associated with the occurrence of diseases. The gut microbiota and the pancreas influence each other, resulting in a "gut microbiota-pancreas axis". Moreover, the gut microbiota may be involved in pancreatic diseases, both through direct bacterial colonization and an indirect effect of small molecules and toxins derived from dysbiosis. Pancreatic diseases such as acute pancreatitis, chronic pancreatitis, autoimmune pancreatitis, and pancreatic cancer are common gastroenterological diseases associated with high morbidity and mortality. The involvement of the microbiota in pancreatic diseases is increasingly recognized. Therefore, modifying the intestinal bacterial flora could have important therapeutic implications on these pathologies. The aim of this study is to review the literature to evaluate the alterations of the gut microbiota in pancreatic diseases, and the role of the microbiota in the treatment of these diseases.

Abstract
In the early stage of acute pancreatitis (AP), abundant cytokines induced by local pancreatic inflammation enter the bloodstream, further cause systemic inflammatory response syndrome (SIRS) by "trigger effect", which eventually leads to multiple organ dysfunction syndrome (MODS). During SIRS and MODS, the intestinal barrier function was seriously damaged accompanied by the occurrence of gut-derived infection which forms a "second hit summit" by inflammatory overabundance. Gastrointestinal microecology, namely the biologic barrier, could be transformed into a pathogenic state, which is called microflora dysbiosis when interfered by the inflammatory stress during AP. More and more evidences indicate that gastrointestinal microflora dysbiosis plays a key role in "the second hit" induced by AP gut-derived infection. Therefore, the maintenance of gastrointestinal microecology balance is likely to provide an effective method in modulating systemic infection of AP. This article reviewed the progress of gastrointestinal microecology in AP to provide a reference for deeply understanding the pathogenic mechanisms of AP and identifying new therapeutic targets.

Abstract
A clear safety profile of probiotics in clinical practice is essential in decision-making for all stakeholders and regulators. Probiotics have been investigated in different target populations, conditions and age groups. This also includes the use of probiotics in critically ill patients. Despite promising results reported with the use of probiotics and synbiotics, there is still a lively discussion regarding the proper and safe use of probiotics among physicians, researchers and regulators. This doubt and debate was sparked by the high incidence in mortality reported in a study with critically ill patients. Whereas no causal relationship has been established since, safety of probiotic has been questioned. In response, an overwhelming body of evidence suggesting that probiotics are safe has been compiled. Moreover, data indicates that probiotics reduce the number of adverse events compared to the control. However, due to a lack of standardised safety reporting in clinical studies, a strong evidence base on probiotic safety remains to be established. Here, we will discuss: (1) the rationale for using probiotics in the critically ill; (2) what happened during the Dutch Pancreatitis trial; (3) what are the known safety risks of probiotics based on the available data; and finally (4) how standardisation in safety reporting can drive probiotic innovation. Building a strong safety profile for probiotic strains will solidify its use in individuals that can benefit the most from microbial modulation.

Abstract
Introduction: The role of pre-, pro-, and synbiotics supplemented to standard enteral nutrition in severe acute pancreatitis (SAP) remains unclear. We performed this updated meta-analysis to determine the value of pre-, pro- and synbiotics supplemented to standard enteral nutrition in predicted SAP. Methods: A systematic search in PubMed, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) databases was performed. Eligible studies were randomized controlled trials (RCTs) that compared the effects of pre-, pro-, and synbiotics supplemented to standard enteral nutrition with control regime in predicted SAP patients. Risk ratio (RR) and mean difference (MD) with 95% confidence interval (95% CI) were used to express the estimates of dichotomous and continuous data respectively. Results: 13 RCTs comprising an aggregate total of 950 patients were eventually enrolled. Pooled results suggested that supplemented use of pre-, pro- and synbiotics effectively shorten the length of hospital stay in Chinese SAP cohorts (6 RCTs, MD = −5.57, 95% CI = −8.21 to −2.93, P < 0.001); however significant differences with regard to remaining clinical outcomes were not detected for all patients. Further analysis based on category of interventions including pre-, pro- and synbiotics also confirmed the findings to be reliable. Conclusions: Supplemented use of pre-, pro and synbiotics reduced the length of hospital stay in Chinese SAP cohorts. And thus, we concluded that pre-, pro- and synbiotics supplemented to standard enteral nutrition may be a potential option for the treatment of SAP patients. However, we also suggest designing further studies with large-scale and rigorous methods of addressing data to establish the effects and safety of supplemented use of pre-, pro- and synbiotics for SAP patients due to the presence of limitations.

Abstract
The PROPATRIA (Probiotics in Pancreatitis Trial) study was a multicenter, double-blind, placebo-controlled clinical trial that aimed to reduce infectious complications in patients with predicted severe acute pancreatitis by the enteral use of a multispecies probiotic preparation. An unprecedented 24 of 152 patients (16%) in the group receiving probiotics died versus 9 of 144 (6%) in the placebo group. This high mortality rate in the probiotic-treated group contrasts strongly with observations from a previous smaller study and from our observations regarding the effects of abundant intestinal lactobacilli in patients with short small bowel (SSB) syndrome. We argue here that a lethal combination of mainly proteolytic pancreas enzymes and probiotic therapy resulted in the high mortality rate of the PROPATRIA trial and that elevated levels of lactic acid produced by bacterial fermentation of carbohydrates were a key contributing factor. We suggest that probiotic therapy may not be counter-indicated for the prevention of secondary infections associated with acute pancreatitis, provided that future clinical studies (i) start probiotic therapy immediately after first onset of disease symptoms, (ii) limit the supply of fermentable carbohydrates, (iii) prevent bacterial (over)growth of patient's own intestinal flora and (iv) massively increase the dose of probiotic bacteria.

Abstract
BACKGROUND/OBJECTIVES The aim of this focused review is to provide a valuable and updated source of information for clinical practice on fluid therapy (FT) and nutritional support in acute pancreatitis (AP). METHODS The review encompasses important new clinical information that has become available for understanding and offering these specific treatments since the 2013 publication of two guidelines, both the joint International Association of Pancreatology and American Pancreatic Association and the American College of Gastroenterology. The 2015 Revised Japanese Guideline is discussed selectively. To this end, the review is divided into 7 sections, including timing and cause of mortality; severity classification systems; predicting severity; response to treatment; nutritional support; fluid therapy and steps for further research. CONCLUSIONS In mild AP, begin oral feeding when nausea, vomiting and abdominal pain are improving. In (predicted) severe AP, feeding decisions should commence by 72 h, offering oral feeding if GI symptoms improve or enteral feeding if patients are symptomatic and/or intolerant to orals. All patients should be offered goal-directed FT during the first 6-12 h of presentation. Cautious FT is advised in those age >55 years or with preexisting organ failure or predictors of developing fluid sequestration.
