Probiotic : A treatment option

in diarrhea and IBS

DIARRHOEA

• Increase in FREQUENCY, LIQUIDITY, VOLUME of stools

• Stool weight more than/equal to 200 gm/day (western diet) or 450 gm/day (indian diet)

• Diarrhea - WHO defines as passage of loose or watery stools; 3 or more per day.

• Among children in the U.S., diarrhea accounts for more than 1.5 million outpatient visits, 200,000 hospitalizations, and ~300 deaths per year.

PSEUDO-DIARRHOEA

Increased frequency but with NORMAL VOLUME

Seen due to local inflammation of rectum (IBS, proctitis)• Patient passes small but frequent stools

TYPES OF DIARRHOEA• ACUTE: less than 2 weeks

• PERSISTENT: 2-4 weeks

• CHRONIC: more than 4 weeks

SYMPTOMS AND SIGNS

IRRITABLE BOWEL SYNDROME (IBS)

Pathophysiology

Antidiarrheal medication is one of the approach for treating IBS

• Loperamide – effective when used prophylactically 2-16mg/d

• Cholestyramine

• Bismuth subsalicylate

NORMAL BACTERIAL FLORA OF THE GI TRACT

• Aerobic and anaerobic bacteria,

• yeast and fungi live into the GI tract 400 m2 of surface area.

• more than 2000 species of commensal bacterial organisms within our bodies

GI flora components


Probiotics• Microbes found in the food supply that enhance human

health.

Criteria: • bacteria of human origin

• able to adhere to the intestinal mucosa

• have potential to colonize in the GI tract

• can produce antimicrobial substances,

• stable against bile, HCl, and other acids, enzymes, and oxygen, and determined to be safe and effective.

Benefits of probiotics….

Mechanism of Action• Suppression of growth or epithelial binding/invasion by pathogenic

bacteria

– 1. Decrease luminal pH

– 2. Secrete antimicrobial peptides

– 3. Inhibit bacterial invasion

– 4. Block bacterial adhesion to epithelial cells

Altered Disease States

Probiotics have been thought to improve or ameliorate a plethora of states, the most commonly reported upon are:

• Various states of diarrhea

• Inflammatory Bowel Disease

• H. Pylori Ulcers

• Urinary Tract Infections

• Vaginal Candida Overgrowth

Diarrhea is the condition most beneficially treated by probiotic therapy.

This can include diarrhea associated with

• antibiotics,

• travel,

• gastroenteritis,

• lactose intolerance,

• and Inflammatory Bowel Disease.

Commercially used probiotic strains.

ROLE OF SACCHAROMYCESBOULARDI

Saccharomyces boulardii

• Saccharomyces boulardii (S. boulardii)-yeast isolated from the skin of Lychees

• non-pathogenic

• thermotolerant yeast

• grows optimally at 370C.

• It is a live yeast that is available as a lyophilized preparation for adults as a 250 mg capsule.

Prajapati P, Patel M, Krishnamurthy R. Saccharomyces boulardii- a probiotic of choice. CIBTech Journal of Biotechnology. 2013 Vol. 2 (2) April-June, pp.1-6

Properties of S boulardii

• resistant to stomach acids and bile acids

• Although the optimal temperature for most strains of Saccharomyces range from 22-30 c, S. boulardii survives best at 37 c.

• S. boulardii is a safe and effective biotherapeutic agent for the treatment of gastrointestinal disease.


Pharmacokinetics

S. boulardii, when given orally -• steady-state concentrations – 3 days• clearance- 3-5 d after discontinuation

• half life -6 hours, • fecal steady state concentration (2 × 107/g) – 3 days

• some types of fiber (psyllium) increase S boulardii levels by 22%, while other type of fiber (pectin) shows no effect.

McFarland LV. Systematicv review and meta-analysis of Saccharomyces boulardii in adult patients. World J Gastroenterol 2010 May 14; 16 (18):2202-2222

Stability of S boulardii

• Probiotics may be available as lyophilized or heat-dried preparations.

• Lyophilized preparations -• stable over one year at room temperature, as long as it is

protected from moisture.


Mechanism of Action

McFarland LV. Systematic review and meta-analysis of Saccharomyces boulardii in adult patients. World J Gastroenterol 2010 May 14; 16 (18):2202-2222

Anti-Microbial Action – Direct Anti-Toxin Effect

• The anti-toxin action-mainly due to small peptides produced by the yeast.

• Able to inhibit enterotoxin and cytotoxic activities of C. difficile by degradation of toxin A and B

• Different types of mechanisms of action. • luminal action• trophic action• mucosal-anti-inflammatory signaling effects.

• S. boulardii may interfere with pathogenic toxins, • preserve cellular physiology, • interfere with pathogen attachment, • interact with normal microbiota


Inhibition of Growth and Invasion of Pathogen

• S boulardii directly inhibits the growth of several pathogens (Candida albicans, E. coli, Shigella, and cell invasion by Salmonella typhimurium.

• This mode of action important for the treatment of (chronic) inflammation of the digestive tract.

Observations :

#3 Therapeutic effects of Saccharomyces boulardii on mild

residual symptoms in a stable phase of Crohn's disease

• Randomized, single-center, double-blind, placebo-controlled pilot study.

• 20 patients with established Crohn's disease suffering from diarrhea and moderate complaints

• Treatment : Saccharomyces boulardii (S.b.) in a dosage of 250 mg t.i.d., initially for two weeks in addition to the basic treatment.

• • Results: reduction in the frequency of bowel movements (5.0 ±1.4 vs. 4.1 ±

2.3 evacuations/day, p < 0.01)•

Plein K, Hotz J Department of Gastroenterology, General Hospital of Celle. Zeitschrift fur Gastroenterologie [1993, 31(2):129-134]

• After this initial phase, the patients were allocated in randomized order to the control group (n = 7) receiving placebo, or to the verum group (n = 10) receiving S.b.(250 mg t.i.d.) for 7 weeks, while the basic treatment was maintained.

• The group treated with S.b. showed a significant reduction in the frequency of bowel movements in the tenth week.No adverse drug events were observed.

#4 Lactobacillus rhamnosus GG in the prevention of antibiotic

associated diarrhea in children• Objective: efficacy of Lactobacillus rhamnosus (Lactobacillus GG) in

reducing the incidence of antibiotic-associated diarrhea.

• Study design: Two hundred two children between 6 months and 10 years of age were enrolled; LGG, 1 × 1010 – 2 × 1010 colony forming units per day, or comparable placebo was administered.

• Results:

• Twenty-five placebo-treated but only 7 LGG-treated patients had diarrhea.

• Lactobacillus GG overall significantly reduced stool frequency and increased stool consistency

• Conclusion: Lactobacillus GG reduces the incidence of antibiotic-associated diarrhea in children treated with oral antibiotics for common childhood infections.
