Pre and probiotics in colorectal cancer Prevention By Dalia Khamis El-DeebDalia Deeb
This document discusses prebiotics, probiotics, and their potential role in preventing colon cancer. It begins with definitions of prebiotics as selectively fermented ingredients that change the gastrointestinal microflora to benefit health. Probiotics are live microorganisms that colonize the intestines and exert beneficial effects. The document explores how gut microbiota can contribute to carcinogenesis and the mechanisms by which probiotics and their short-chain fatty acid products may prevent colon cancer, such as decreasing pH, modulating compounds, and inducing apoptosis in altered cells. It concludes that while studies have shown potential, more research is still needed to fully understand mechanisms and generate conclusive evidence on using prebiotics and probiotics to prevent and manage colon
The term probiotics is a relatievly new word meaning “for life” and is currently used to name bacteria associated with beneficial effects for humans and animals. The development of resistance to range of antibiotics by some important pathogen has raised a possibility of return to pre antibiotic dark ages. So there was need of new treatment paradigm to be introduced to treat periodontal diseases. This need was fulfilled by the introduction of probiotics. Probiotics are counterparts of antibiotics thus are free from concerns for developing resistance, further they are body’s own resident flora hence are most easily adapted to host. The buzz about probiotics has become a roar but despite great promises, probiotics work is limited to gut. Periodontal works are sparse and need validation by large randomized trials. It can be said probiotics are still in “infancy” in terms of periodontal health benefits, but surely have opened door for a new paradigm of treating disease on a nano molecular mode. Novel species are likely to be added in the future as research data
accumulate. In-depth understanding of the intrinsic microbial ecological control of commensal microbiota may introduce new putative species to this discussion.

The document discusses the health benefits of probiotic foods. It begins with a brief history of probiotics and defines them as live microorganisms that benefit the host. Probiotics can establish a healthy gut flora, produce antimicrobial substances, and boost immunity. They help treat conditions like antibiotic-associated diarrhea, hepatic encephalopathy, and H. pylori infections. The document examines the selection of probiotic strains and establishes their role in supporting digestive and overall health.
This document discusses the benefits of probiotics beyond just treating diarrhea. Probiotics have been shown to help with infectious diarrhea, inflammatory bowel disease, and irritable bowel syndrome. Recent research also indicates probiotics may help prevent bacterial translocation, diabetes, hypertension, dyslipidemia, osteoporosis, H. pylori infection, and depression or anxiety by modulating the gut microbiome and immune system.
1. The document discusses gut microbiota and its relationship to health. It provides background on methods used to study the microbiome, such as next generation sequencing and fecal transplantation.
2. Intrinsic and extrinsic factors that influence microbiome composition are examined, including genetics, diet, medication, and disease states. Many diseases are associated with distinct microbiome profiles.
3. Studies of population cohorts explore the effects of various factors on the microbiome and identify biomarkers. Comparisons of healthy, IBS, and IBD groups show differences in taxonomic profiles and metabolic pathways between conditions.
1) The study examined the effects of probiotic supplementation with Lactobacillus paracasei or Lactobacillus rhamnosus on gut bacteria composition and host metabolism in humanized extended genome mice.
2) Probiotic exposure altered the gut microbiome and resulted in changes to hepatic lipid metabolism, lowered plasma lipoprotein levels, and stimulated glycolysis. It also impacted amino acid metabolism, methylamines, and short-chain fatty acid levels.
3) Multivariate analysis of metabolic profiles from multiple compartments, including biofluids, tissues, and cecal contents, provided a systems-level view of the host response to probiotic interventions. This integrated approach demonstrated how probiotics can
Probiotics in periodontal health and diseaseAysha Jabeen
This document discusses probiotics and their potential role in periodontal health. It defines probiotics as live microorganisms that provide health benefits when consumed. Probiotics may help periodontal health through several mechanisms, including competing with pathogenic bacteria, modulating the immune system, and producing antimicrobial substances. Clinical studies have shown probiotics can reduce gingivitis and inhibit the growth of periodontal pathogens. However, risks like sepsis must be considered, and more research is still needed to identify the best probiotic strains and delivery methods for oral health applications.
The document discusses the significance of the gut microbiome and potential roles of probiotics. It notes that the gut microbiome contains trillions of microbes and plays an important role in health, immunity, and metabolism. Factors like diet, lifestyle, antibiotics, and other medications can disrupt the normal gut microbiome and lead to dysbiosis, which has been linked to various conditions. Probiotics may help maintain a balanced gut microbiome and mitigate disruption through interactions with the immune system and production of metabolites. Future research could further explore probiotics and manipulation of gut flora to treat certain diseases.
Safety assessment of probiotics for human useDiwas Pradhan
The document summarizes safety assessment procedures for probiotic bacteria intended for human use. It defines probiotics and lists common strains used. Safety assessment includes taxonomic identification, assessing absence of pathogenicity and undesirable metabolic activities, determining antibiotic resistance and potential for horizontal gene transfer, and validation in animal models. Human studies are also important to establish tolerability and identify any adverse effects. Overall, the document outlines guidelines and criteria for evaluating probiotic safety prior to human use based on established scientific principles and evidence from the literature.

o Critical illness is characterized by a loss of commensal flora and an
overgrowth of potentially pathogenic bacteria, leading to a high
susceptibility to nosocomial infections
Probiotics significantly reduced the incidence of infectious
complications, including new episodes of VAP(Ventilator-associated
pneumonia )in critically ill patients.
o In the largest systematic review and meta-analysis of probiotics to date,
in 30 trials enrolling 2972 patients
Probiotics protect the gut barrier, attenuate pathogen overgrowth,
decrease bacterial translocation and prevent the infection.
Probiotic therapy with L. plantarum currently
demonstrates the most significant effect on the
reduction of infections..

Rousseaux C, Thuru X, Gelot A et al.Nat Med 2007;13:35–37.
Abstract
• Abdominal pain is common in the general population and, in
patients with irritable bowel syndrome, is attributed to visceral
hypersensitivity.
• Oral administration of specific Lactobacillus strains induced the
expression of mu-opioid and cannabinoid receptors in
intestinal epithelial cells, and mediated analgesic functions in
the gut-similar to the effects of morphine.

General Comments
• Adjunct to rehydration therapy reduced the duration of diarrhea
• Strain specific In efficacy and safety .
• The safety and clinical effects should not be generalized….
• A lack of evidence regarding the efficacy of a certain probiotic(s) does not
mean that future studies will not establish health benefits.
• The efficacy has to be confirmed in well-conducted RCTs,*

30. Probiotics in gastrointestinal
disorders
The precise mechanism's of action of probiotics has not thus far been
clarified.
o Potential mechanisms to consider include:
Modulation of GI immunity by:
altering inflammatory cytokine profiles
down regulating pro inflammatory cascades
inducing regulatory mechanisms in a strain-specific manner;
Inhibiting pathogenic bacterial adherence;
Acidification of the colon by nutrient fermentation;
Enhancement of epithelial barrier function;
Induction of opioid and cannabinoid receptors in intestinal epithelial cells;
Reduction of visceral hypersensitivity, spinal afferent traffic, and stress

Childhood Diarrhea
The microbiota is maintained in a stable ecology, and it appears that
probiotics are very helpful in shortening the course of acute
gastroenteritis diarrhea [Szujewsku H.2007. Guandalini S. 2008].
• There are numerous studies to establish this.

Reduction of diarrhea duration of little
more than 1 day, and to be exerted mostly
on diarrhea due to rotavirus.
The effect is strain-dependent, and dose-
dependent, with doses of at least 10
billion/d being necessary.
It is clear that starting Saccharomyces boulardii, LGG, or strains of
Lactobacillus reuteri are extremely helpful in shortening the course of
the diarrhea [Szujewsku H.2007. Guandalini S. 2008].

• Pouchitis can be prevented, and remission can be
maintained with the use of the probiotic VSL#3[Mimura T.2004].
Therapy reports , ProbioticsVSL#3( Escherichia coli Nissle, S.
boulardii and LGG; )was most successful [Miele E.2009).
• Regulate dysbiosis that occurs in simple ulcerative colitis [Floch 2012].
• Dysbiosis, which is seen with C. difficile, can be corrected in
selective ulcerative colitis patients and reduce symptom control By
FMT [Brace C.2014]
This is the same dysbiosis that is treated with FMT.

• FMT permits the administration of over 500 strains of human organisms.
• They certainly fit the definition of a probiotic in that they are human
organisms administered to benefit health.(Floch 2012)
• There are many papers in the literature that demonstrate a probiotic —
namely, VLS#3—which is effective in ulcerative colitis, pouchitis, and
Irritable Bowel Syndrome.(Guandalinni S 2010)
It enables total biological stimulation of the
immune system and seeding of the host basic flora

Chennai 2016
Synbiotics :manipulate the intestinal
microbiota and could improve the
quality of life for celiac patients
,especially on associated disease such
type 1 diabetes and other autoimmune
disorders (eczema herpitiforme )
(RossiMet al 2010 journal of Leukocyte Biology 87:749-751)
42. Probiotics & Pancreatitis
• The safe use of probiotics are raised by the outcomes of several clinical
trials.( Ridwan 2008 )
– A mixture of six probiotic bacteria (L. acidophilus, L. casei, L.
salivarius, L. lactis, B. bifidum, and B. infantis) used to treat patients
with severe acute pancreatitis ,
Increased their risk of mortality ,!!!!!!
– although this bacterial mixture inhibited the growth of most
pathogens that caused pancreatitis complications in the preclinical
animal studies. (Snydman 2008 Clin Infect Dis)

43. Lactose intolerance
• Application of pre- and probiotics to improve the clinical symptoms of
lactose intolerance
Lactobacillus delbrüeckii in a milk product can deliver β-galactosidase
activity.
Lactobacillus bulgaricus and Streptococcus thermophiles alleviate the
lactose intolerance through their enzyme lactase when the product
reaches the intestinal tract.
• lactose intolerance can be reduced by β-galactosidase enzyme of the
lactic acid bacteria which present in them. ( Masood et al. 2006)
(Roel J. Vonk 2012)
Chennai 2016
Meta-analysis show inconsistent results
(Levri et al. J Fam Pract 2005)
Benefit remains unproven.
Probiotics have an effect by two levels:
1.The Hydrolysis of lactose in the milk product
2.The hydrolytic capacity of probiotic to reduce the actual amount of lactose
44. Probiotics and Hepatic
Encephalopathy
Probiotics (VSL#3 or lactobacillus species.)are more effective than
placebo in;
– Reducing hospitalizations among cirrhotic patients,
– Improving MHE, (minimal hepatic encephalopath)
– Preventing progression of MHE to OHE. (overt HE)
• Probiotics appear to have similar effectiveness to lactulose in regard to
these outcomes.
• The potential role of probiotics in the treatment of minimal hepatic
encephalopathy in patients with cirrhosis.”still in research.

46. Summary
• Probiotics are a therapeutic class being increasingly used for a
variety of GI disorders.
• Probiotics appear to alter intestinal microflora and may exert
their effect's) by a variety of mechanisms.
• Many species of probiotics exist and it is generally accepted that
all probiotics are not created equal.
• Efficacy may be due to a single strain or multiple strains or a
combination of different probiotics.
• Probiotics do not provide additional benefit compared with
standard therapy alone.

52. Criteria for use a probiotic
• It must be safe for consumption:
– Not pathogenic or carrying antibiotic resistance genes
– Not degrading to intestinal mucosa or conjugating for bile
acids
• It must survival intestinal transit: Acid and bile tolerant
• It must adhere to mucosal surface and colonize the intestine
(at least briefly,)
• Produce antimicrobial substances and antagonize pathogenic
bacteria
• At least one phase 2 study documenting benefit.
• It must be stable during processing and storage…….
(Borchers et al. 2009)
Chennai 2016
53. Misconception with probiotics
• All probiotic supplements are basically the same.
• Could have different effects on health.
• Can replace medications.
• Food and supplement labels provide accurate microbe counts.
• Yogurts are generally a good source of probiotics.
• The More Strains The merrier and better .
• The Higher the Number of Billions, the Better.
• The Best Probiotics are Kept in the Fridge.
• lyophilisation ensure that the probiotics remain viability at room
temperature.
• Probiotics may not be used while taking antibiotics Course.

54. COLONIZATION
• A common misconception is that probiotics must always colonize the
intestinal tract to exert their effects.
• Some probiotics (e.g., Bifidobacterium longum and Bacteroides
thetaiotamicron) become part of the human intestinal microflora,
whereas others (e.g., Lactobacillus casei and B. animalis) may not .
• Non colonizing probiotics indirectly exert their effects either in a transient
manner as they pass through or, more likely, by remodeling or influencing
the existing microbial community .

55. Infection:
• Infective endocarditis or bacteremia (Extremely rare-) represent
0.05% -0.4%
• liver abscess caused by lactobacillus rhamnosus (500 ml/d).
Recovered with surgical drainage and antibiotics.

Safety of using probiotics
Chennai 2016
Review of 200 cases of lactobacillus infection 1950-2003;
114 cases of bacteremia*
Mortality rate 32%
All patients had significant morbidity including
malignancy
62 cases of endocardidtis with 22.9% mortality rate.
(Cannon et al. Eur J Clin Microbiol Infect Dis 2005.)
56. Safety PROBIOTICS
disadvantages Kelli Cooper 2013
• Metabolic and enzymatic effect :theoretically may have some
effect on metabolism of bile salts and mucous. (not reported
yet )
• Immunological effects : when we have immunodeficient
patient and ingest large amount of certain probiotics cause
relapse of autoimmune reactions.
• Gene transfer: if genetically modified probiotics used may
harbor antibiotic resistant genes.
Risk is transferring of antibiotic resistance genes to the host,
as L. reuteri and L. plantarum have been found to carry such
genes. (Egervarn MJ Appl Microbiol. 2009)
Chennai 2016
57. Chennai 2016
The use of probiotics during pregnancy, in neonates, and in
children has not been associated with any adverse
immunologic effects,(SrinivasanJ Pediatr Gastroenterol Nutr 2006)
Safety PROBIOTICS
disadvantages Kelli Cooper 2013
Infection : when probiotics, given to persons with
severe underlying disease, may cause systematic
infection.
Bacteremia and fungemia , occurrence in ill
patients and immuno deficient individuals has
also been reported . (Roy M Robins 2006)
Bacteremia reported in premature babies with
short-gut syndrome (Hala fatima 2010)
58. Dosage
Recommended Dosage for Probiotics
• Different brands of probiotics can contain anywhere from one to 10 billion
colony-forming units or CFUs.
• To maintain a healthy digestive tract, a probiotic with one to two billion
CFUs is recommended.
• However, if you are taking antibiotics, or if you have symptoms of a
bacterial imbalance such as diarrhea, you can take a probiotic with up to
10 billion CFUs until the problem clears up.
• To maintain microorganism balance, take a probiotic of one to two billion
CFUs daily or every other day.
• To correct a problem, probiotics containing 10 billion CFUs can be taken
daily for up to two weeks. -

59. Dose of probiotics for neonates
• The probiotic supplementation in infants should be done carefully,
especially those who are preterm because preterm of impaired immune
system, poor nutrition, and frequent exposure to harmful microorganisms.
• Recommended
- Neonates (less than 32 weeks age of gestation): 3 x 109 cfu/day
- Extremely low birth weight infants: 1.5 x 109 cfu/day until they reach
enteral feeds of 50-60 ml/kg/day
- The probiotic dose should be diluted in 1.0 to 1.5 mL of breastmilk or water.

60. Facts about Probiotics
• Not all Probiotics have same action and functions
• Probiotics are specific strains
• Probiotics are not absolute treatment , mainly adjuvant , ameliorate
inflammation
• There are side effects for probiotics , fungioma , carditis
• Probiotics absolutely not effective in pancreatitis
• Probiotics are not a treatment for asthma

Interestingly, reduced microbial diversity was associated
with diseases such as Crohn’s disease [Manichanh et al.
2006] and eczema in early life. [Forno et al. 2008]
62. As with diseases
• Most probiotics tested to date are more effective than
placebo in inducing or maintaining IBD remission
• There is good evidence to support the efficacy of S. boulardii
and LABs and the combination of the two for AAD, VSL#3 for
pouchitis, and B. infantis 35624 for IBS.
• Probiotics decrease the duration of symptoms in acute
infectious diarrhea.
• Probiotics, including E. coli Nissle 1917, LGG, and VSL#3 are
as effective as standard therapy (mesalamine) in inducing or
maintaining remission in UC or CD. When added to standard
therapy,

63. As with safety
• Probiotics have been shown to be safe in immunocompetent hosts in an
outpatient setting.
• Administration of probiotics to immunocompromised, chronically ill,
hospitalized patients with GI disorders, and indwelling catheters may
predispose to probiotic sepsis, probiotics may increase translocation of
bacteria into the bloodstream.
Chennai 2016
Summary
64. What MUST be finally resolved
• Optimal doses,
• Duration of treatment,
• Comparison of different strains and different probiotics,
• Single versus combination probiotics,
• Combination of probiotics with prebiotics,
• Efficacy of various probiotics in different disease states,
• Safety of probiotics in debilitated patients
• Safety in patients with compromised gut epithelial integrity
