See here for ISAPP letter to the Clinical and Translational Gastroenterology editor regarding this paper.

See related post Probiotics and D-Lactic Acid Acidosis in Children

Rao and colleagues incriminated probiotics in the induction of D-lactic acidosis in their paper titled “Brain fogginess, gas and bloating: a link between small intestinal bacterial overgrowth (SIBO), probiotics and metabolic acidosis” (Rao et al. 2018). Eamonn Quigley MD, Bruno Pot, microbiologist and I on behalf of ISAPP authored a letter to the editor of Clinical and Translational Gastroenterology (currently In Press), summarizing many medical and other concerns with the study design, execution and conclusions.

It is regrettable that one poorly controlled paper can lead to such negative backlash on the probiotic field. Respectable media outlets including Newsweek, Science Daily, Psychology Today, the Daily Mail, MSN.com, and others blindly reported the results of this study without critical analysis of the paper. These stories advance the opinion that probiotics are potentially harmful and should be sold only as drugs. This flies in the face of many scientific studies that document safety compounded with safe, worldwide consumption for decades of probiotic foods and supplements.

Bifidobacterium as a genus does not yield D-lactate as a metabolic end product. Some Lactobacillus species do (Table 19.1 in Pot 2014). Among common probiotic Lactobacillus species, the following are classified as species that can produce D-lactic acid: L. acidophilus, L. gasseri, L. delbrueckii subsp. bulgaricus (one of the 2 yogurt starter culture bacteria), L. fermentum, L. lactis, L. brevis, L. helveticus, L. plantarum and L. reuteri.  Individual strains within each species may vary with regard to levels of D-lactic acid produced.

The observational nature of the Rao et al. paper precludes any conclusive link between probiotic consumption and symptoms observed.  The authors acknowledge that they have only established an association between probiotic use and the symptoms, but the misleading paper title suggests an intention to indict probiotics, even in the absence of evidence.  It is much more likely that the patient population with underlying SIBO in this study sought relief from their gut symptoms by use of probiotics rather than the probiotics being the cause of their symptoms.

D-lactic acidosis is a rare but serious condition, typically occurring in people with short bowel syndrome. These patients should know that D-lactate-producing probiotics are not recommended for them. In people with a normal gut, D-lactate produced by members of the gut microbiota – including some probiotics – is metabolized by other members of the gut microbiota and does not accumulate. Thus, under normal circumstances, D-lactic acidosis does not result from consumption of D-lactic acid-producing probiotics. The patients in the Rao et al. study showed very low levels of D-lactic acid, calling into question if these SIBO patients were even acidotic.  Moreover, the D-lactic acid that was present was not proven to be a result of probiotic growth. This is important, as intestinal bacteria including Escherichia coli also produce D-lactic acid. In cases of SIBO, numerous metabolites are produced in the small intestine (including alcohol), leading to a variety of SIBO symptoms, possibly including the poorly defined phenomenon of “brain fogginess”.  Many issues that should have been were not addressed in the Rao et al. paper.

The real tragedy with the publication of this paper is that – similar to many such media scares in the past – it is may cause harm.  The sensationalist headlines may dissuade safe probiotic use in people who can truly benefit from them. Scientists and clinical researchers – both academic and from industry – must remain diligent in assessment and reporting of any probiotic harms. However, the Rao et al. paper is not an example of this.

CBER to hold public workshop on regulation of biologics

FDA’s Center for Biologics Evaluation and Research (CBER) is convening a public workshop Sept 17 in Rockville MD on the Science & Regulation of Live Microbiome-Based Products Used to Prevent, Treat, or Cure Diseases in Humans. It is now open for registration (free). See here for the program and here for additional info.

The evidence for efficacy, the safety and the regulatory framework for probiotics other live microbiome based products will be discussed. Prof. Dan Merenstein MD, ISAPP’s current Vice President, will speak on evidence, research and clinical use of probiotics for antibiotic associated diarrhea. Although the title suggests the meeting will focus on drugs, Dr. Bob Durkin from the Center for Food Safety and Applied Nutrition (CFSAN) of the FDA will speak on probiotic foods and dietary supplements.

This workshop is an opportunity for stakeholders to share with FDA and NIH concerns regarding the regulatory approach to probiotics adopted by the FDA. The path for development of probiotic drugs is reasonably clear. But the road to develop probiotic foods, supplements or microbiome-based dietary strategies to compensate for deficient microbiota is less so. These products are intended to improve gut function, nutritional status, immune status, metabolic properties and more. These are legal functions for foods and supplements, but the FDA doesn’t seem to see it that way.

The FDA has for the most part has approached probiotics as drugs (Sanders et al. 2016). Since probiotics are live microbes, and since CBER deals with drugs that are derived from living sources, CBER often oversees human research on probiotics. But there is no mechanism within CBER to oversee foods and supplements, and hence, human research on probiotics tends to be shunted into the investigational new drug (IND) process. But, the legal definitions of drugs and foods overlap – both can impact the structure/function of the human body and both can reduce the risk of disease. So conducting such research on probiotic foods – and not as part of the IND rubric – should be possible. Perhaps progress on this front can be achieved in the CBER workshop in September.

In a press announcement, FDA Commissioner Scott Gottlieb MD shared FDA perspective on probiotics and promoted this CBER conference. A couple of issues are noteworthy in this announcement by Gottlieb. First, the term ‘probiotic’ is used. Over the years, the FDA largely avoided use of this term, instead favoring the term live biotherapeutic product (LBP). But these terms are not synonymous. Probiotic is defined as a live microorganisms that, when administered in adequate amounts, confers a health benefit on the host (Hill et al. 2014). It spans multiple regulatory categories. A LBP is by definition a drug. The fact that Gottlieb used the term ‘probiotic’ may signal that he recognizes that not all probiotics are drugs. Second, Gottlieb’s announcement shows awareness that probiotics are legitimate components in foods and dietary supplements and states that the FDA is “committed to working with industry on efforts to provide information that can help consumers make more informed choices about these products.” This is a welcome statement to many researchers involved in probiotic foods and supplements in the United States. It suggests that the FDA is willing to look beyond probiotics as LBPs and develop regulatory approaches for research and claims appropriate to foods and supplements.

Innovation in this field, which has the potential to benefit many people globally, requires regulatory approaches that do not obstruct. Participation in this workshop may lead to improvements that both protect public safety and facilitate academic and industry researchers in the United States on the path to discovery.

ISAPP conducts webinar on definitions in microbiome space for ILSI-North America Gut Microbiome Committee

Dr. Mary Ellen Sanders presented a webinar July 23, 2018 – covering basic definitions of microbiota-mediated terminology – to the ILSI-North America Gut Microbiome Committee, which you can listen to here. The objective was to update the committee about terms with clear and actionable consensus definitions in the microbiome space. ISAPP is committed to proper use of terms such as ‘probiotics’ and ‘prebiotics’, as evidenced by the consensus panels it has convened (see here and here) on these topics. Definitions of some newly emerging terms such as postbiotic, abiotic, and probioceuticals are less clear.

Some issues covered in this webinar include comparison with historic definitions, minimum criteria for commercial probiotic and prebiotic products, contrasting probiotic food with fermented food, and a brief discussion of imminent taxonomy changes for the genus, Lactobacillus.

The webinar is now available here.

Welcome Seppo Salminen – ISAPP’s New President

An interview with Prof. Seppo Salminen

ISAPP President 2018-2021

 

1) What are your goals as the next president of ISAPP? 

My goal is to work together with the board and the members to advance excellence in the science of probiotics and prebiotics and to share research and conclusions with as wide an audience as possible. It is also my goal to leverage ISAPP’s scientific  expertise to work with organizations to promote  evidence-based applications of probiotics and prebiotics to advance health and well-being of people.

2) What do you hope to see the organization accomplish during your tenure?

ISAPP is engaged now in North America, Europe and Asia so maybe we can be really be global and reach out to South America and  connect with researchers in Africa as we have done with Professor Reid earlier. I would like to work toward common goals with more industrial, scientific and regulatory experts from different parts of the world.

3) What changes do you foresee in the field of probiotics and prebiotics in the next few years?

 I foresee rapid development in probiotics and prebiotics. There will be novel microorganisms developed and novel sources of prebiotics and this direction leads to challenges in safety evaluation and efficacy demonstration  as well as communication of the results to larger audiences.

4) How did you originally become involved in ISAPP?

I was originally invited to one ISAPP meeting, then to the next one, then to the third one and at the end was invited to be a member of the board, which I considered a special honour!

5) Which ISAPP meeting was your favorite so far?

They all have been excellent, but some I remember (each for different reasons) are the ones in Barcelona, New York, Chicago and Berkeley – and now Singapore. Of course, the one in Turku, Finland as well – when you help organize a meeting like that you certainly remember even on a minute-by-minute basis.

Thank you Prof. Salminen and welcome!

ISAPP board members share expertise in probiotic workshop in Buenos Aires

ISAPP board members, Prof. Seppo Salminen and Dr. Mary Ellen Sanders, along with over a dozen other renowned experts from the Southern Cone, Europe and Canada, participated in a workshop in Buenos Aires organized by Ricardo Weill of Instituto Danone Cono Sur April 26-27, 2018. The purpose of the workshop was two-fold. One goal was to share current science about probiotics with each other and with Codex Alimentarius and regulators from Argentina, to encourage a science-based approach to global probiotic standards that may end up with a draft of guidelines to be considered by the Codex Alimentarius late this year. Secondly, the intent is to convert each of the presentation topics into a chapter for a Spanish and English-language book to be published in the fall.

Two experts, Drs. Gabriel Vinderola and Rocio Martin, who participated in this meeting, will also serve as invited experts to the 2018 ISAPP meeting in Singapore June 5-6.

The concepts advanced by ISAPP in its papers on the scope and use of the term ‘probiotic’ and on the concept of core benefits and its regulatory implications were featured at this meeting. “The meeting was organized by Instituto Danone but it was devoid of all commercial content,” said Salminen.

Want some guidance on knowing which probiotic products have been tested for which clinical benefits, and understand the level of evidence supporting those benefits? Check out the 2018 versions of Clinical Guide to Probiotic Products Available in USA and Clinical Guide to Probiotic Products Available in Canada. Currently, these are the only 2 geographical regions covered by this initiative, although they are considering expanding to other regions. This guide is updated annually. Some changes for 2018 include addition of new indications ‘Mood and affect’, ‘Liver health’, ‘Weight management’ (Canada) and ‘Seasonal allergies’ and ‘Eczema/Dermatitis-Adult’ (United States). Evidence is reviewed independently by six academic experts and graded as Level I (highest), II or III. A grade of Level I requires evidence from at least one properly designed randomized human trial. This guide is produced by the Alliance for Education on Probiotics, and is an industry funded effort (see industry sponsors for US and Canadian versions).

ISAPP to host live webinar: Microbial metabolism associated with health

Update April 16, 2018:  Recording and slides from the webinar available here.

The International Scientific Association for Probiotics and Prebiotics (ISAPP), in partnership with the International Life Sciences Institute (ILSI) Europe’s Prebiotics and Functional Foods Task Forces, has jointly organized a free webinar, titled Microbial Metabolism Associated with Health. The webinar runs April 12th, 2018 at 15:00 CET, and will highlight recent activities of both ISAPP and ILSI on the beneficial aspects of gut microbial fermentation. The specific focus will be on gut microbiota functions, the effects of the intestinal microbiota on selected nutrients and non-nutrients, and the health benefits of fermented foods. Scientists from both academia and industry may find the webinar of interest. Sign up here.

Webinar participants will learn the status of the science making the links between live microorganisms in the diet and host health. The host gut microbiota is a key factor in determining gut function, nutritional status, biochemical transformations of food and the overall impact on health. This diverse microbial community inhabiting the human gut assists in food metabolism and contributes to the bio-availability of nutrients and non-nutrients; it also has an extensive metabolic repertoire that complements mammalian enzymes in the liver and gut mucosa. Microbial metabolism is an important factor to consider when discussing the management of host health and conditions such as obesity and metabolic syndrome.

The enhanced nutritional and functional properties of fermented foods are being increasingly recognized; not only do microbes transform the substrates and form bioactive or bioavailable end-products, but also, fermented foods contain live microorganisms genetically similar to the strains found in probiotics. The webinar will cover the possible interactions of fermented foods and beverages with the gut microbiota, and potential links to health.

The 90-minute live webinar will be hosted on StreamGo, and will include a question and answer period at the end. There is no cost; however, participants are required to register online beforehand.

Speakers:

  • Effects of the Intestinal Microbiota on Selected Dietary Components
    a) Introduction and Background to the Activity (Dr. Colette Shortt, Johnson & Johnson, UK)
    b) Impact of Intestinal Metabolism and Findings (Prof. Ian Rowland, University of Reading, UK)
  • Health Benefits of Fermented Foods: Microbiota and Beyond (Prof. Robert Hutkins, University of Nebraska, USA)

ISAPP works to have evidence-based usage of probiotics to prevent antibiotic-associated diarrheoa implemented in UK

January 12, 2018. Antibiotics are amongst the most commonly prescribed drugs in UK hospitals. However, as well as treating infection they can cause disruption to the gastrointestinal microbiota. This can lead to the relatively common side-effect of antibiotic-associated diarrhoea (AAD) which often delays discharge. More concerning is that a disruption to the normal gut microbiota can lead to reduced resistance to opportunistic pathogens such as Clostridium difficile, leading to C. difficile infection, a potentially severe or fatal infection. Based on the available evidence, probiotics are a safe and effective adjunct to antibiotics to reduce the risk of developing AAD and for the primary prevention of CDAD. The International Scientific Association of Prebiotics and Probiotics has reviewed available data and supports several published assessments, which recommend probiotics as adjunctive therapy for prevention of AAD and CDAD.

This effort was led by Dr. Claire Merrifield BSc MBBS PhD, Speciality Registrar in General Practice, St. Mary’s Hospital, Imperial College Healthcare Trust, Imperial College London and Prof. Daniel Merenstein, MD, Department of Family Medicine, Georgetown University Medical Center and ISAPP Board Member and Treasurer.

baby crying colic

ISAPP Digs Deeper into Evidence on Probiotics for Colic with New Meta-Analysis

January 3, 2018.

Evidence exists for gut microbiota differences between infants with and without colic, with one probiotic strain of particular interest therapeutically for colicky infants: Lactobacillus reuteri DSM17938. Discussion groups convened at the 2014 and 2016 ISAPP meetings, both led by Prof. Michael Cabana MD MPH of University of California, San Francisco, and member of ISAPP’s board of directors, focused on the existing randomized, controlled trials and how they might inform medical recommendations.

The discussion group at the 2014 ISAPP meeting in Aberdeen Scotland resulted in a paper describing the individual patient data meta-analysis (IPDMA) protocol, which was published in BMJ Open.  The 2016 ISAPP meeting in Turku Finland culminated in the publication of this IPDMA in the journal Pediatrics: Lactobacillus reuteri to treat infant colic: a meta-analysis. Dr. Valerie Sung, Royal Children’s Hospital, The University of Melbourne and Murdoch Children’s Research Institute, was lead author of this paper, whose coauthors included a team of 11 other experts spanning three continents.

This high quality meta-analysis used individual patient data rather than group means to get a more accurate picture of the efficacy of the probiotic. The paper concluded that L. reuteri DSM17938 is effective and can be recommended for breastfed infants with colic. However, data are lacking for efficacy in formula-fed infants.

“Any single randomized clinical trial involves a great deal of time and resources from investigators, institutions and most importantly, patients. By working together, our team was able to combine data to learn more about the effects of L. reuteri DSM 17983 on the treatment of infant colic. This analysis is a great example of the power of close international collaboration by clinical investigators.”

fermented foods

Fermented foods, health and ISAPP

By Mary Ellen Sanders PhD, Executive Science Officer, ISAPP

It seems that fermented foods have ‘arrived’. Just within the community of ISAPP board members, fermented foods and their importance to health have been a topic of great interest. The idea that adding foods containing live microbes may be sound dietary advice has been reflected in many venues and formats, as seen here:

  • Bob Hutkins:
    • Presented “Health benefits of fermented dairy foods: microbiota and beyond” at 5th YINI Summit (Danone Institute) Fermented Foods and Health: The Intersection of Gut Microbiota and Fermentation Microbes on October 18, 2017.
    • Will convene a discussion group at ISAPP 2018 in Singapore “Taking advantage of fermented foods for health.”
    • Submitted a paper on counts of live microbes in fermented foods “A survey of live microorganisms in fermented foods”
    • Along with lead author Maria Marco and others summarized a discussion group on fermented foods convened at the 2016 meeting of ISAPP in Turku, reflected in this popular Current Opinions in Biotechnology article, Health Benefits of fermented foods: microbiota and beyond.
  • Gregor Reid:
  • Mary Ellen Sanders
  • Seppo Salminen:
  • ISAPP board of directors
    • In 2015, published several comments to the US Dietary Guidelines Advisory Committee, presenting the scientific rational for fermented foods to be part of the US dietary guidelines. See here and here (and for a comment on prebiotic inclusion in dietary guidelines, see here)
    • Oversaw the ISAPP Science Translation committee, which published a consumer-friendly infographic and related materials on Fermented Foods.

ISAPP will continue to work to get this topic recognized by nutrition professionals globally.

probiotics for healthy people infographic

ISAPP releases new infographic: “Probiotics for Healthy People”

November 20, 2017. Probiotics are most commonly studied with for populations with a specific condition—frequent examples include diarrhea, irritable bowel syndrome, and pouchitis. But what kind of evidence exists on probiotics for healthy people?

A new ISAPP infographic gives an overview of what we know about the use of probiotics in healthy individuals. The resource was developed by ISAPP’s Science Translation Committee and approved by  the ISAPP board of directors.

“Studying health benefits in healthy people is a challenge. But there is evidence that probiotics can provide dietary management of some digestive conditions that don’t reach the level of diagnosed disease as well as prevent of some common infectious diseases and. These, and other benefits, are of value to healthy people,” says ISAPP’s Executive Science Officer, Dr. Mary Ellen Sanders. The new infographic  emphasizes it is not necessary to take probiotics to be in good health, but they may serve as a useful addition to a healthy lifestyle.

Research investigating how probiotics can affect healthy individuals through their microbiomes is ongoing in laboratories around the world, and ISAPP continues to track the latest findings.

ISAPP Releases Series of Informational Videos on Probiotics and Health

October 10, 2017. Probiotics are a hot topic—an online search for information yields millions of hits. But how much of this easily-accessible information is scientifically accurate?

The clinicians and scientists serving on the ISAPP Board of Directors constantly receive questions about what’s true when it comes to probiotics and prebiotics. That’s why ISAPP decided to commission a series of four informational videos on probiotics. These videos were overseen by members of our board of directors without input from industry, but industry provided educational grants for their production.

The four new videos focus on these topics:

  • What is a probiotic?
  • Benefits of probiotics
  • Are all probiotics the same?
  • How to choose a probiotic

Watch for the videos to roll out during the month of October 2017! They’ll appear here on the ISAPP website video page.

With our mission to advance scientific excellence in probiotics and prebiotics, ISAPP is committed to helping consumers access science-based information on probiotics and prebiotics. To stay up to date on ISAPP news, please sign up for our monthly newsletter!

The International Scientific Association for Probiotics and Prebiotics (ISAPP) is pleased to announce the opening of registration for its June 2018 international symposium in Singapore— and welcomes all interested participants around the world.

“Typically, ISAPP meetings are open only to invited experts and scientists from member companies,” says ISAPP Executive Science Officer Mary Ellen Sanders. “But in 2018, ISAPP features an open-registration event June 5th and 6th, welcoming all interested in the probiotic and prebiotic fields, including academicians, industry, regulators, and students.”

The 2018 conference will also mark the first time an ISAPP event has been hosted by a country in Asia. In choosing to congregate in Singapore, says Prof. Gregor Reid, the co-chair of this conference and featured speaker, “ISAPP recognizes the first-rate scientific expertise and growing markets in Asian countries.” He adds, “Our 2018 meeting in Singapore will allow us to better engage those in the Asian region while maintaining a top-notch program featuring global scientists.”

The theme of the conference is “Key Scientific Drivers Behind Probiotic and Prebiotic Applications.” Event’s speakers include global thought leaders in probiotic and prebiotic science, including Dr. Liping Zhao (China), Dr. Sarah Lebeer (Belgium), Dr. Glenn Gibson (UK), Dr. Seppo Salminen (Finland), and more. Plenary sessions will cover topics ranging from pediatric health and allergy to prebiotic mechanisms and strategies for health claim substantiation.

Invited experts and member company scientists will congregate on June 7th, after the main conference, for a “Day of Discussion” related to probiotics and prebiotics.
