Abstract
Gut microbial irregularities can lead to increased gut inflammation and gut membrane damage in people with long covid. Symptoms such as cough and breathlessness are apparent in Covid 19 patients with harmful gut bacterial overgrowth. In Covid patients, antibiotic and dexamethasone treatment also aggravates gut microbial imbalances. Lactobacillus supplementation has been shown to lessen upper respiratory tract infection, increase gut bacterial diversity, improve gut wall integrity, reduce gastrointestinal symptoms and gut inflammation, decrease oxidative stress and improve immunity. This study analysed the efficacy of probiotics and prebiotics combined supplements in reducing the severity and longevity of symptomatic Covid infection. 126 participants with Covid symptoms consumed two capsules a day for a month of a supplement containing 5 species of Lactobacillus and chicory inulin. 32% of participants were in the early phase of infection, and 68% were in the late phase. Both early and late phase participants showed significant improvements in cough, fatigue, and subjective wellbeing after 30 days of intervention. The gut symptoms of 82% of the participants improved after a month of intervention. Inulin and Lactobacillus strains need to be studied further robustly to determine whether they provide additional benefits. Healthcare practitioners can use the results of this study to consider symbiotic interventions for those with Covid symptoms.

Plain language summary
Milk and dairy products are good sources of protein, calcium and other nutrients. However, many people experience lactose intolerance due to their digestive tract's inability to digest lactose, resulting in symptoms such as flatulence, abdominal pain and diarrhoea. Oral administration of certain friendly live microorganisms or probiotics can help digest lactose more efficiently as they have greater β-galactosidase (β-gal) activity. β-galactosidase is an enzyme responsible for the digestion of lactose in the dairy products. A total of twelve studies were included in this meta-analysis. The results of this meta-analysis showed an improvement in the symptoms of lactose intolerance in adult patients, following probiotic administration. Probiotic administration was also found to enhance the digestion of lactose and calcium absorption in adult patients. Healthcare professionals can use the results of this study to understand the potential benefits of oral supplementation of probiotics for adult lactose intolerance patients. However, further studies are needed to understand the relationship between calcium absorption and lactose digestion after probiotic administration.
Abstract
This meta-analysis aimed to investigate the effect of probiotic administration on adults with lactose intolerance. Twelve studies were identified from databases such as PubMed, Cochrane Library, and Web of Knowledge based on the inclusion and exclusion criteria. The effect size was estimated using the standardized mean difference (SMD), and Cochrane's Q test was used to evaluate the statistical heterogeneity of the effect size. Moderator analysis, including meta-ANOVA and meta-regression, were performed to determine the cause of heterogeneity in the effect size using a mixed-effect model. Egger's linear regression test was conducted to evaluate publication bias. The results showed that probiotic administration alleviated the symptoms of lactose intolerance, including abdominal pain, diarrhea, and flatulence. Among them, the area under the curve (AUC) showed the greatest decrease following probiotic administration (SMD, -4.96; 95% confidence interval, -6.92 to -3.00). In the meta-ANOVA test, abdominal pain and total symptoms decreased with monostrain probiotic administration. This combination was also effective for flatulence. The dosage of probiotics or lactose was significantly associated with a reduction in the total symptom score, and the linear regression models between the dosage and SMD were found to be Y = 2.3342 × dosage - 25.0400 (R2 = 79.68%) and Y = 0.2345 × dosage - 7.6618 (R2 = 34.03%), respectively. Publication bias was detected for most items. However, even after effect size correction, the probiotic administration effect for all items remained valid. The administration of probiotics was effective at improving adult lactose intolerance, and it is expected that the results of this study could help improve the nutritional status of adults by increasing their consumption of milk and dairy products in the future.

Plain language summary
Many fermented foods are associated with health benefits, including fermented dairy products. Whereby diary itself is part of many nutritional guidelines, the guidances rarely distinguish between dairy and fermented dairy. This qualitative, systematic review sought to capture how consumption of fermented milk products influences health. The review included 108 studies, with over 70% reporting beneficial health outcomes. A small number of studies reported insignificant or neutral results and four unfavourable ones. The aspects of health that were considered included lactose digestion and tolerance, gut health and disease, diarrhoea and constipation, irritable bowel syndrome, cardiovascular health and disease, hypertension, blood lipids, cancer risk, colorectal/breast/prostate cancer, weight and body composition, diabetes risk and metabolic syndrome and bone health. The authors concluded that eating fermented dairy products aided lactose digestion and showed a consistent link with reduced risk of breast and colorectal cancer, type 2 diabetes, and improved weight maintenance, cardiovascular, bone, and gastrointestinal health. As dairy appears to increase the risk for prostate cancer, fermented dairy seems to be no different here to unfermented dairy at increasing the risk. Some potential mechanisms are proposed in the discussion section, how fermented dairy may elicit its health benefits. Given the predominant health benefits of fermented dairy, the authors encouraged to include fermented dairy into national nutrition guidelines and stress distinction between dairy and fermented dairy products. This review captures current evidence of the widespread health benefits of fermented dairy consumption worthwhile considering in clinical practice. In the absence of more clear findings in relation to prostate cancer and prevention, a cautious approach to dairy and fermented dairy consumption may be warranted.
Abstract
Consumption of yogurt and other fermented products is associated with improved health outcomes. Although dairy consumption is included in most dietary guidelines, there have been few specific recommendations for yogurt and cultured dairy products. A qualitative systematic review was conducted to determine the effect of consumption of fermented milk products on gastrointestinal and cardiovascular health, cancer risk, weight management, diabetes and metabolic health, and bone density using PRISMA guidelines. English language papers in PubMed were searched, with no date restrictions. In total, 1057 abstracts were screened, of which 602 were excluded owing to lack of appropriate controls, potential biases, and experimental design issues. The remaining 455 papers were independently reviewed by both authors and 108 studies were included in the final review. The authors met regularly to concur, through consensus, on relevance, methods, findings, quality, and conclusions. The included studies were published between 1979 and 2017. From the 108 included studies, 76 reported a favorable outcome of fermented milks on health and 67 of these were considered to be positive or neutral quality according to the Academy of Nutrition and Dietetics' Quality Criteria Checklist. Of the 32 remaining studies, the study outcomes were either not significant (28) or unfavorable (4), and most studies (18) were of neutral quality. A causal relationship exists between lactose digestion and tolerance and yogurt consumption, and consistent associations exist between fermented milk consumption and reduced risk of breast and colorectal cancer and type 2 diabetes, improved weight maintenance, and improved cardiovascular, bone, and gastrointestinal health. Further, an association exists between prostate cancer occurrence and dairy product consumption in general, with no difference between fermented and unfermented products. This article argues that yogurt and other fermented milk products provide favorable health outcomes beyond the milk from which these products are made and that consumption of these products should be encouraged as part of national dietary guidelines.

Lactobacillus acidophilus NCFM
PROBIOTICS DATABASE, OptiBac Probiotics
2020
Abstract
Lactobacillus acidophilus NCFM® is a very well-researched strain - certainly the most researched strain of the acidophilus species - which has been extensively tested in vitro, and also in both animal studies and in human clinical trials. There are actually over 45 clinical trials on this strain, a fact which confirms its position as one of the best probiotic strains in the world, with a well-deserved and a secure place in this database of the most well-researched probiotics on the planet. It has been used in a broad range of studies focusing on its potential to support many areas of gastrointestinal and general health, including immune function, antibiotic-associated gut disturbances, and the symptoms of Irritable Bowel Syndrome (IBS). The L. acidophilus NCFM® strain was first identified when isolated from a human source back in the early 1970's. Its strain name, NCFM®, is derived from an abbreviation of the “North Carolina Food Microbiology”, which is the name of the research laboratory at North Carolina State University (NCSU) where the strain was first discovered. You may also see Lactobacillus acidophilus NCFM® referred to as Lactobacillus acidophilus ATCC 700396, NCK56, N2 as well as NCFM®. This strain is often used in clinical trials in combination with Bifidobacterium lactis Bi-07.

Plain language summary
Irritable bowel syndrome (IBS) is the most common functional gut disorder with symptoms primarily of bloating and diarrhea. Recently these symptoms have been associated with small intestinal bacterial overgrowth (SIBO), which occurs when bacteria from the colon resides in the small intestine. The aim of this study was to determine the efficacy of probiotics in improvement of symptoms of IBS patients with SIBO. In this prospective trial, five patients with IBS and SIBO and 21 patients with IBS without SIBO were given probiotic capsules twice a day for 30 days. Participants completed an IBS severity questionnaire at three visits throughout the trial. At the end of the trial, a 71.3% decrease of the total IBS score was detected in patients with IBS and SIBO, compared with those without SIBO. This study found there are clinical benefits from probiotic supplementation in IBS patients with SIBO. Based on these findings, the authors conclude larger, randomised studies be undertaken based on this prospective design.
Abstract
The effect of probiotics on small intestinal bacterial overgrowth (SIBO) in irritable bowel syndrome (IBS) has never been studied so far. In this prospective trial, five patients with IBS and SIBO and 21 patients with IBS without SIBO were administered an oral capsule containing Saccharomyces boulardii, Bifidobacterium lactis, Lactobacillus acidophilus, and Lactobacillus plantarum (Lactolevure®) every 12 h for 30 days. SIBO was defined by quantitative culture of the third part of the duodenum; IBS was defined by the Rome III criteria. Severity of symptoms was graded by the IBS severity scoring system (SSS). The primary study endpoint was the efficacy of probiotics in improvement of symptoms of IBS in patients with SIBO. Thirty days after the end of treatment, a 71.3% decrease of the total IBS score was detected in patients with IBS and SIBO compared to 10.6% in those without SIBO (p 0.017). A similar decrease was achieved among patients with constipation-predominant IBS without SIBO. Post-treatment satisfaction from bowel function was greater in patients with SIBO. Similar satisfaction improvement was found among patients with diarrhea-predominant IBS irrespective from SIBO; pain intensity score decreased in patients with constipation-predominant IBS irrespective from SIBO. The benefit of probiotics was greater among patients with a pro-inflammatory cytokine pattern in the duodenal fluid. This is the first study that prospectively demonstrated superior clinical efficacy of probiotics in patients with IBS with SIBO. Analysis also showed considerable benefit from probiotic intake regarding certain symptoms of patients with diarrhea-predominant and constipation-predominant IBS.Trial registration: ClinicalTrials.gov identifier NCT02204891.

Plain language summary
Ulcerative Colitis (UC) is a chronic debilitating inflammatory bowel disease that may need lifetime management. Dietary management of UC by eliminating food antigens that may be causing a delayed immune response is one of the approaches used widely to manage the disease. Food intolerance, mediated by immunoglobulin G antibodies in response to food antigens that are otherwise harmless, could be one cause of UC. Low levels of digestive enzymes may result in poor digestion of glucose, amino acids, and glycerol, followed by an immune reaction that leads to food sensitivities. Ninety-seven UC patients were enrolled in this open-label, stratified, prospective, randomised controlled trial to evaluate the effect of an elimination diet versus a sham diet (a normal healthy diet). Following an IgG-specific exclusion diet for six months resulted in the alleviation of UC symptoms and an improvement in health-related quality of life. Further studies are needed to confirm the effectiveness of the exclusion diet since the intervention group did not show a significant reduction in IgG antibody levels. These results can be used by healthcare professionals to understand the potential role of exclusion diets in the management of UC.
Abstract
BACKGROUND Most patients with ulcerative colitis (UC) rely predominantly on medication for disease control. Diet interventions can reduce pharmaceutical expenditures and prolong remission. We designed a prospective study to evaluate whether an immunoglobulin G (IgG)-guided exclusion diet would improve symptoms and quality of life (QoL) in patients with UC. METHODS The 6-month diet intervention included 97 patients with UC, who were randomly divided into an intervention group (n = 49) and a control (n = 48) group. Individual diet plans were created for the intervention group according to IgG titers; the control group ate a healthy diet as normal. Observational indices included disease activity, extraintestinal manifestations, nutritional status, and QoL. Relationships between food-specific IgG antibodies and these indices were also analyzed. RESULTS At baseline, there were no significant differences between the groups. Food-specific IgG antibodies were detected in 70.10% of participants. After intervention, the Mayo score was significantly lower in the intervention group than in the control group (2.41 ± 0.89 vs 3.52 ± 1.15, P < 0.05). The number of patients with extraintestinal manifestations decreased from 7 to 2 in the intervention group and from 6 to 5 in the control group. As for nutritive indices, the intervention group had higher mean body mass index and albumin than the control group (23.88 ± 3.31 vs 21.50 ± 6.24 kg/m2, respectively, P < 0.05; 48.05 ± 6.39 vs 45.72 ± 5.48 g/L, respectively, P < 0.05), whereas prealbumin and transferrin were not significantly different between the groups. QoL improved after food exclusion (P < 0.05). CONCLUSIONS An IgG-guided exclusion diet ameliorated UC symptoms and improved QoL. Interactions between IgG-based food intolerance and UC warrant further study.

Plain language summary
The gut microbiome is a complex ecosystem of different micro-organisms, such as bacteria, viruses and fungi, living in the human intestines. It’s involved in numerous functions, such as extracting energy and nutrition from food, protecting against disease-causing microorganisms, and supporting the immune system of the host, and therefore affecting human health and disease. This paper is a review of studies on the effects of antibiotics on the gut microbiota. It outlines how different types of antibiotics can alter the intestinal environment and the composition of the microbes, resulting in various physiological changes that can trigger disease. Relevant mechanisms, such as inflammatory response and the use of intestinal nutrients by infectious bacteria are discussed. Finally, it discusses faecal microbiota transplantation (FMT) and probiotics as treatment approaches, aimed at restoring a disturbed intestinal environment.
Abstract
The intestinal microbiota is a complex ecosystem consisting of various microorganisms that expands human genetic repertoire and therefore affects human health and disease. The metabolic processes and signal transduction pathways of the host and intestinal microorganisms are intimately linked, and abnormal progression of each process leads to changes in the intestinal environment. Alterations in microbial communities lead to changes in functional structures based on the metabolites produced in the gut, and these environmental changes result in various bacterial infections and chronic enteric inflammatory diseases. Here, we illustrate how antibiotics are associated with an increased risk of antibiotic-associated diseases by driving intestinal environment changes that favor the proliferation and virulence of pathogens. Understanding the pathogenesis caused by antibiotics would be a crucial key to the treatment of antibiotic-associated diseases by mitigating changes in the intestinal environment and restoring it to its original state.

Plain language summary
The role of the gut microbiota in health and disease is far reaching and there is a growing body of evidence on the therapeutic potential of probiotics in gastrointestinal (GI) disease. Patients with GI disease present with a variety of symptoms and current evidence suggests probiotics may play a role in ameliorating these adverse symptoms. The purpose of this review is to update the previous systematic review and incorporate new findings on the role of probiotics in adult patients presenting with a variety of GI symptoms. Based on the updated evidence, this study confirms the finding that specific probiotics are beneficial for certain lower GI problems. According to this review, the author deems this study useful for clinicians when recommending probiotics to patients.
Abstract
BACKGROUND In 2013, a systematic review and Delphi consensus reported that specific probiotics can benefit adult patients with irritable bowel syndrome (IBS) and other gastrointestinal (GI) problems. AIM: To update the consensus with new evidence. METHODS A systematic review identified randomised, placebo-controlled trials published between January 2012 and June 2017. Evidence was graded, previously developed statements were reassessed by an 8-expert panel, and agreement was reached via Delphi consensus. RESULTS A total of 70 studies were included (IBS, 34; diarrhoea associated with antibiotics, 13; diarrhoea associated with Helicobacter pylori eradication therapy, 7; other conditions, 16). Of 15 studies that examined global IBS symptoms as a primary endpoint, 8 reported significant benefits of probiotics vs placebo. Consensus statements with 100% agreement and "high" evidence level indicated that specific probiotics help reduce overall symptom burden and abdominal pain in some patients with IBS and duration/intensity of diarrhoea in patients prescribed antibiotics or H. pylori eradication therapy, and have favourable safety. Statements with 70%-100% agreement and "moderate" evidence indicated that, in some patients with IBS, specific probiotics help reduce bloating/distension and improve bowel movement frequency/consistency. CONCLUSIONS This updated review indicates that specific probiotics are beneficial in certain lower GI problems, although many of the new publications did not report benefits of probiotics, possibly due to inclusion of new, less efficacious preparations. Specific probiotics can relieve lower GI symptoms in IBS, prevent diarrhoea associated with antibiotics and H. pylori eradication therapy, and show favourable safety. This study will help clinicians recommend/prescribe probiotics for specific symptoms.

Plain language summary
The cause of IBS has yet to be established, however the role of the gut microbiota in modulating symptoms is the subject of significant recent research. This randomised, double-blind, placebo controlled trial of 88 healthy subjects with chronic diarrhoea, aimed to assess the impact of ingestion of probiotic strain Bacillus subtilis C-3102 over an 8 week period on patient symptoms. Approximately 8.5 billion spores of Bacillus subtilis C-3102 were administered daily to the treatment group, once a day, immediately after breakfast. The results, after 8 weeks of ingestion, showed: an improved Bristol Stool Chart score; a reduction in stool frequency; significantly decreased abdominal sounds; and significantly altered relative abundance of Lachnospira, Actinomyces and SMB53. Intake of 4 weeks or more were required to achieve these results. Even though this was a small study, nutrition and lifestyle practitioners looking to support the digestive health of IBS patients may wish to consider adding this probiotic strain to their recommendations on the grounds of improved symptoms of diarrhoea.
Abstract
Ingestion of Bacillus subtilis C-3102 spores (C-3102) has relieved the symptoms of diarrhoea in piglets and changed the composition of gut microbiota in humans. Recently, it was suggested that the composition of the human gut microbiota affects stool consistency. In this study, a double-blind, randomised, placebo-controlled trial was conducted to assess the preventive effects of chronic diarrhoea in healthy volunteers with loose stools by ingestion of C-3102. The results showed that oral doses of C-3102 tablets significantly decreased the Bristol Stool Scale score and stool frequency, and also significantly improved abdominal sounds. With regard to gut microbiota, the relative abundance of Lachnospira, Actinomyces and SMB53 were significantly changed. This study shows that C-3102 could be effective for treating loose stools (Trial registration: UMIN000022583, http://tinyurl.com/ya4refqn ).

Plain language summary
Acute radiation-induced diarrhoea is a potentially fatal side effect of radiotherapy for abdominal or pelvic cancers. The mechanisms are not yet known, but effects of the radiation on the microbiota may be a factor and probiotic treatment may therefore be beneficial. The authors of this meta-analysis looked at randomised controlled trials of probiotics in the prevention of radiation-induced diarrhoea with probiotics (there were not enough trials to evaluate probiotics for the treatment of radiation-induced diarrhoea). Only six studies qualified for inclusion into this meta-analysis, with a total of 917 patients (490 receiving probiotics, 427 controls). Compared with placebo, patients receiving probiotics had a significantly lower risk of developing diarrhoea, but there was no significant reduction in anti-diarrhoea medication use or Bristol scale stool form. Most studies did not report adverse events from probiotic treatment. The meta-analysis was limited by several factors: variety of bacterial strains, dosages and timings used, differences in cancer treatment (dose of radiotherapy, radiotherapy alone or with chemotherapy), variability of patient populations and diseases, and diagnostic criteria for diarrhoea.
Abstract
BACKGROUND Radiotherapy is commonly used for abdominal or pelvic cancer, and patients receiving radiotherapy have a high risk developing to an acute radiation-induced diarrhea. Several previous studies have discussed the effect of probiotics on prevention of radiation-induced diarrhea, but the results are still inconsistent. OBJECTIVE We performed a meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy of probiotic supplementation for prevention the radiation-induced diarrhea. METHODS Relevant RCTs studies assessing the effect of probiotic supplementation on clinical outcomes compared with placebo were searched in PubMed, EMBASE, and the Cochrane Library databases (up to March 30 2016). Heterogeneity was assessed with I2 and H2, and publication bias was evaluated using sensitive analysis. RESULTS Six trials, a total of 917 participants (490 participants received prophylactic probiotics and 427 participants received placebo), were included in this meta-analysis. Compared with placebo, probiotics were associated with a lower incidence of radiation-induced diarrhea (RR: 0.55; 95% CI: 0.34-0.88; P = 0.01; I2: 87%; 95% CI: 75%-94%; H2: 2.8; 95% CI: 2.0-4.0). However, there is no significant difference in the anti-diarrheal medication use (RR: 0.68; 95% CI: 0.40-1.14; P = 0.14) or bristol scale on stool form (RR: 0.64; 95% CI: 0.35-1.17; P = 0.14). CONCLUSION Probiotics may be beneficial to prevent radiation-induced diarrhea in patients who suffered from abdominal or pelvic cancers during radiotherapy period.
