2IRRITABLE BOWEL SYNDROME
M. E. Money. M.D.
3Definition of IBS
- IBS is a functional bowel disorder in which
abdominal pain or discomfort is associated with
defecation or a change in bowel habit. Bloating,
distension, and disordered defecation are
commonly associated features. - Irritable bowel syndrome a global perspective.

4Diagnostic Criteria (Rome III)
- Onset of symptoms at least 6 months before
diagnosis - Recurrent abdominal pain or discomfort for gt3
days per month during the past 3 months - At least two of the following features
- Improvement with defecation
- Association with a change in frequency of stool
- Association with a change in stool form

6Mainstream concepts about IBS
-
- Exact cause of irritable bowel syndrome not
known. - Multiple factors thought to contribute to
etiology. - To date an 'IBS gene' has not been identified.
- The concept of IBS as a diagnosis of exclusion is
not acceptable any more. - The treatment of IBS is targeted at symptom
relief. - Cognitive behavioral therapy is very beneficial.
M. E. Money. M.D.
7Predisposing, and precipitating factors for
irritable bowel syndrome
- Predisposing factors
- Genetic predisposition
- Early life experiences
- Intergenerational transmission of illness
behavior - Gender
- Precipitating Factors
- Acute and chronic stress (life events)
- History of abuse
- Infection and inflammation
- Bacterial flora and small bowel bacterial
overgrowth - Intestinal gas and motility

11Treatment options conclusion in Prescire
International 2009
- There is currently no way of radically modifying
the natural course of recurrent irritable bowel
syndrome - Patients frequently complain of occasional bowel
movement disorders, associated with abdominal
pain or discomfort, but they are rarely due to an
underlying organ involvement. Even when patients
have recurrent symptoms, serious disorders are no
more frequent in these patients than in the
general population, unless other manifestations,
anemia, or an inflammatory syndrome is also
present - Irritable bowel syndrome a mild disorder purely
symptomatic treatment. Prescrire.Int. 18(100),
75-79. 2009

12Accuracy of symptom-based criteria for diagnosis
of IBS in primary care1
- Reviewed 25 primary diagnostic studies.
- 2 research questions
- Performance of symptom-based criteria in
excluding organic GI
disease. - Performance of signs and symptoms in
identifying IBS - Conclusion organic disease cannot be
accurately excluded by symptom-based IBS criteria
alone. - 1Jellema, P. et al. Systematic review accuracy

13How did this research get started?
- In September 2001, one of my patients came in
demanding that I prescribe something to help
with her diarrhea that would occur after she ate
out in restaurants with her family By that time,
I had given pancreatic enzymes to 2 patients in
my practice for after meal diarrhea due to
surgery on the pancreas with good results and
decided to give it to her as a clinical
experiment. - She returned 4 weeks later, reporting that 1
pill before the meal worked just fine, 4 made
her constipated. - By Christmas, I had prescribed it to another 10
individuals and all but one had complete symptom
relief.
M. E. Money, M.D
14How did this research get started?
- By Christmas, I had also researched the current
recommendations for IBS-D and had discovered
pancreatic enzymes were not mentioned. I had
also checked with 2 specialists to assure there
was no harm in using enzymes, and decided to do
my own study comparing pancreatic enzymes to
placebos. - The study was approved by the Washington County
Review Board in January 2002 and the first
patients were enrolled in February. - It concluded in 2003. 49 patients enrolled, 10
dropped out, and 25/39 who did participate
picked the enzymes as the effective agent.

26Effectiveness of pancreatic enzymes
- A retrospective review was recently completed of
all of the patients in my practice who had the
diagnosis of IBS and had been treated by me from
2001-2010 to evaluate the effectiveness of the
enzymes. - 278 patients had received a diagnosis of spastic
colon or IBS - 134 excluded since they had been treated by
another practitioner - 144 seen by me, and 104 had been offered PEZ
- 86/104 patients returned for follow-up, and 82.5
(71) reported positive improvement

28Example of new patient
- 43 yr female seen by me as a new patient 7/24/09
- History Complains of intermittent increased
loose stools after meals for 11 yrs, sometimes at
night if eats late. She wonders if she has IBS.
Symptoms may last for weeks once it gets started,
otherwise only when eats out in restaurants.
Worse with spicy foods, onions, garlicky Italian
meals and tomatoes. - Exam entirely normal. 64 tall, 161
- Chronic medical problems other than above Asthma
- Current meds Zyrtec, Advair Diskus, Ventolin
inhaler - Mother has similar digestion problem.
- Patient had never had a colonoscopy.
28
M. E. Money. M.D.
29New patient continued
- Patient referred to gastroenterologist who wrote
Patient states she has cramping, watery diarrhea
alternating with constipation, up to 10x/day,
mild in nature..symptoms are suggestive of IBS. - Investigation by gastroenterologist
- Colonoscopy negative
- X-rays for the stomach and small intestine were
normal - Blood tests for Celiac disease was normal
- Biopsy of colon negative for pathology
- Treatment Patient encouraged to try probiotics
by gastroenterologist.
M. E. Money. M.D.
30New patient continued
- Additional testing ordered by me
- Stool for fat SMALL amount (8/19/09)
- Fecal elastase-1 487 (normal gt200) (test for
pancreatic insufficiency) - Patient seen 9/4 in office. Probiotics tried by
patient but did not prevent post restaurant
dining diarrhea. I therefore gave the patient
some samples of prescription pancreatic enzymes
to try before restaurant meal or triggers.
They worked with the first meal! - Current treatment Pancreatic Enzymes before
trigger meals eliminates both the abdominal
pain and diarrhea.
M. E. Money. M.D.
31Why do the enzymes work?
- For the last 8 years, I have pursued trying to
figure out why the pancreatic enzymes work. This
presentation will focus on my current hypothesis
and why making the diagnosis of irritable bowel
syndrome-diarrhea may limit further research
into this condition.
M. E. Money. M.D.
32Pancreatic Enzymes
- Composition
- Amylase, Lipases, Proteases, Co-lipases, other
enzymes - Known Action
- Initiates digestion of carbohydrates, lipids and
proteins in the stomach - Amylase potentiates the action disaccharidases by
10-20x. - (Quezada-Calvillo, R. et al. Contribution of

34Incidence of diarrhea occurring after eating
- 50 of patients suffering with the diarrhea or
mixed form of IBS related symptoms to eating. -
- However, the current definition of IBS does not
encourage nor require the physician to inquire
about any precipitating factor such as the
condition occurring ONLY after eating.
M. E. Money. M.D.
35Differential diagnosis for IBS
- Celiac Sprue/gluten enteropathy
- Lactose intolerance (inherited or 2nd to mucosal
damage) - Inflammatory bowel disease
- Colorectal carcinoma
- Lymphocytic and collagenous colitis
- Acute diarrhea due to protozoa or bacteria
- Small-intestinal bacterial overgrowth (SIBO)
- Diverticulitis
- Endometriosis
- Pelvic inflammatory disease
- Ovarian cancer
- WGO Practice Guideline IBS 2009
M. E. Money. M.D.
36What is missing from this differential diagnosis?
- 1. Bile acid malabsorption diarrhea
- 2. Pancreatic insufficiency
- 3. Carbohydrate Malabsorption
- Alpha glucosidases (disaccharidases) deficiencies
(maladigestion of starches) - Congenital sucrase-isomaltase deficiency
- Fructase deficiency
- ? Possible disaccharidase inhibition
M. E. Money. M.D.
37Bile acid malabsorption
- Bile acid malabsorption can occur in patients
with or without an intact gall bladder - Bile acid malabsorption(BAM) may affect up to
30-50 of patients with chronic diarrhea - Can be treated with bile acid binding agents
Welchol, Cholestyramine, Questran - Diagnosis by measurement of serum 7alphaC4 (not
available for routine testing)
M. E. Money. M.D
38Diarrhea predominant IBS (IBS-D) fact or fiction
- Dr. Saad Habba, gastroenterologist in NY,
analyzed all patients seen by him over the last 8
yrs for IBS-D. - 575 patients seen, only 303 patients completed
all of the studies. Of these 303 patients, 204
(68) responded to bile acid binding agents with
resolution of diarrhea. - Diarrhea Predominant Irritable Bowel
Syndrome-Diarrhea Fact or Fiction. Habba,S.,
Medical Hypotheses 76(2011) 97-99.
M. E. Money. M.D
39Pancreatic insufficiency
- Pancreatic insufficiency was found in 6.1
(19/314) patients who had been diagnosed as
having IBS-D by the Rome Criteria. This was
determined by the measurement of the fecal
elastase-1 concentration in the stool. Patients
were then treated with pancreatic enzyme
supplements with a statistical improvement in
stool frequency, consistency, and abdominal pain. - Some Patient With Irritable Bowel Syndrome
May Have Exocrine Pancreatic Insufficiency.
Leeds, J et al, Clinical Gastroenterology and
Hepatology 2010 8433-438.
M. E. Money. M.D
40Carbohydrate malabsorption
- Carbohydrate malabsorption and intolerance is
suggested by the patients clinical history. The
relation of symptoms to feeding and the
occurrence of remission while fasting are crucial
to the history. In older children and adults the
symptoms can resemble those of dyspepsia or
irritable bowel syndrome (IBS)The diagnosis of
functional bowel disease usually is made without
evaluation of carbohydrate digestion symptoms
from IBS and carbohydrate intolerance can be
confused easily. - Disaccharide Digestion Clinical and Molecular
Aspects. Robayo-Torres, C. et al Clinical
Gastroenterology and Hepatology. 20064276-287
M. E. Money. M.D.
411 Lactose malabsorption
- Frequency Isolated deficiency in 16-24 of
patients with IBS and in 12 of patients with
functional bowel complaints. (Autosomal
recessive, CgtT 13910, Intron 13 or MCMG 6 gene.) - Is usually combined with fructose, sorbitol,
glucoamylase, sucrase, and maltase deficiency
among patients with functional GI complaints. - Disaccharide Digestion Clinical and Molecular
Aspects. Robayo-Torres, C. et al Clinical
Gastroenterology and Hepatology. 20064276-287
M. E. Money. M.D.
42Carbohydrate malabsorption syndromes
- 1 Lactose Maldigestion
- Due to Lactase deficiency,
- (a beta-glucosidase)
- Symptoms after the ingestion of milk products
- Abdominal pain
- Cramps
- Urgent diarrhea
- Time of onset variable depending upon quantity
and sensitivity of patient
- Disaccharide Maldigestion
- Due to alpha-glucosidase(s) deficiency
- Symptoms after the ingestion of carbohydrates
- (lettuce, beans, corn, etc)
- Abdominal pain
- Cramps
- Urgent diarrhea
- Time of onset variable depending upon quantity
and sensitivity of patient
M. E. Money. M.D.
43Digestion of starches
- Initial hydrolysis of starches begin with the
action of amylase from the saliva. 95 of
starches are not broken down until they reach the
small intestine where pancreatic amylase breaks
the starch into smaller units maltose,
maltotriose, and limits dextran size.
M. E. Money. M.D.
44Digestion of disaccharidesalpha-glucosidases
- Further hydrolysis of carbohydrates after
amylase involves the brush border disaccharidases
also known as alpha-glucosidases - Maltase
- Isomaltase
- Sucrase
- Trehalase
- Gluco-amylase
M. E. Money. M.D.
45Alpha-glucosidase inhibition
- Drugs Acarbose ( a diabetic medication to
reduce absorption of carbohydrates by preventing
absorption). - Side effect gt30 patients experience
diarrhea - Spices and foods
- gt1000 known to affect a-glucosidases
- Examples
- Clove extract
- Quercetin (found in onions, 5x more potent
than acarbose) - Some spices gt1000x more potent than acarbose
(verbal report Dr. Buford
Nichols) - Bacterial Overgrowth
M. E. Money. M.D.
46Sucrase-isomaltase deficiency in adults and
varied symptoms
- Sucrose-Isomaltose Malabsorption in an Adult
Woman - (Sonntag, W. M. et al, 1964, Gastroenterology
4718.) - 20 Greenlandic Eskimos found to have sucrose
malabsorption - 8 adults, only 1 with symptoms
- (McNair, et al. 1972, Sucrose malabsorption in
Greenland, Br. Med J. 219.) - Ringrose (1980) 13 adult patients with bx proven
SI def. - 5 had persistant or intermittent symptoms since
childhood - 2 symptoms in childhood, disappeared again until
20 40. - 3 symptoms first appeared in first or second
decade. - (1980, Dig. Dis. Sci. 25384)
- Gudmand-Hayer (1985) Studied 31 children, and 12
adults hospitalized in Greenland. Of the 12
adults, 8 had a long-lasting history of chronic
diarrhea and abdominal complaints.
M. E. Money. M.D.
47Sucrase-isomaltase and glucoamylase deficiency in
children
- 1-2 of children with severe diarrhea from birth
are found to have an inherited sucrase-isomaltase
disaccarhidase deficiency - Recent research by Dr. Buford Nichols (Baylor
College, Houston, Texas) in collaboration with
Dr. Susan Baker ( Woman and Children Hospital of
Buffalo, NY ) have found 26 of children with
digestion symptoms have difficulty digesting
starch due to a deficiency of glucoamylase.
M. E. Money. M.D.
48More support for maldigestion as possible cause
of diarrhea
- A very low-carbohydrate diet improves symptoms
and quality of life in IBS-D patients. 2009 - Prospective Study
- 17 enrolled with moderate to severe IBS-D
- Initially had 2 weeks of standard diet, then 4
weeks of very low (20gm carbohydrate/day). - 13 completed the study. 10 (77) reported
adequate relief for all 4 weeks on the low carb
diet stool number decreased, QOL improved, and
decrease in pain. - Clin Gastroenterol Hepatol. Austin, GL Dalton,
CB et.al. 2009 June 7(6) 706-708.el.doi10.10167
/j.cgh.2009.02.023
M. E. Money. M.D.
49More support for maldigestion as possible cause
of diarrhea
- In Indonesia, biopsies taken from the small
intestine were examined for concentration of
Lactase, Sucrase, and Maltase from 13 patients
with chronic diarrhea, and compared to biopsies
from 34 patients with dyspepsia. - Results All of enzyme concentrations from the
patients with chronic diarrhea were statistically
lower than those with dypepsia. - Examination of small bowel enzymes in chronic
diarrhea. J Gastroenterol Hepatol. Simadibrata,
m., et al.18(1) 53-6.
M. E. Money. M.D.
50Working hypothesis
- Diarrhea occurring after meals may actually be
a subclinical form of inherited or acquired
maldigestion, possibly related to a bile acid
malabsorption or a mild deficiency, relative
ineffectiveness or suppression of one or more
enzymes amylase, lipase, the disaccharidases, or
others.
M. E. Money. M.D.
51Summary
- The current Rome Criteria may be limiting
appropriate research and treatment for a subset
of IBS-D patients who recognize the direct
association of symptoms with meals or triggering
foods. The relationship to meals should be sought
in obtaining the history from patients. - A high percentage of these patients probably have
a subclinical form of maldigestion which may be
substantially improved by the use of enzymes or
bile acid binding agents when taken immediately
before eating the triggering meal.
M. E. Money. M.D.
52Proposed new diagnosis
- Intermittent Maldigestion Condition
- (IMC)
- Symptoms of increased bowel movement(s),
occurring after eating a specific meal type or
trigger according to the patient, which may be
altered in form or consistency. Symptoms may
occur immediately after eating or several hours
later and do not have to occur daily. -
M. E. Money. M.D.
53Potential treatment options for patients with
diarrhea after meals
- Over the counter agents
- Fiber capsules (which absorbs extra liquids)
- Calcium (which slows down the motility
naturally), - Enzyme supplement Essential Enzymes 500 mg
(by Source Natural), an over the counter
supplement (1-3) before eating any trigger meal
or daily as needed. - Prescription medications from a physician
- Pancreatic enzymes examples ZenPep 20,000
lipase, Creon 24 (1-3capsules) before eating any
trigger meal or daily as needed. - Bile acid binding drugs Questran 1-2
packages/day Welchol 625 mg (1-3) before eating
any trigger meal or daily as needed.
M. E. Money. M.D.
54Future research questions
- What is the incidence of sucrase-isomaltase
deficieny in adults with diarrhea after eating? - Do over the counter enzyme supplements work as
well as the prescription pancreatic enzymes? - How/why do certain food items cause the diarrhea?
- Do the foods suppress the disaccharidase action
or amylase from the pancreas or speed up the
motility? - Are there specific genes that are predispose a
person to having this problem?
