Crohn's disease begins with crypt inflammation and abscesses, which progress to tiny focal aphthoid ulcers. These mucosal lesions may develop into deep longitudinal and transverse ulcers with intervening mucosal edema, creating a characteristic cobblestoned appearance to the bowel.
Small bowel involved
involved in 80% of
cases
Gross rectal bleeding is rare, except in
75‒85% of cases of Crohn colitis.
Fistula, mass, and abscess development
is common
Stool analysis and culture to rule out bacterial, fungal, or parasitic infection as the cause for diarrhea
X-ray: On x-ray, bowel wall is affected asymmetrically
and segmentally, with skip
areas between diseased segments.
EGD: Endoscopic appearance is patchy, with
discrete ulcerations separated by segments
of normal-appearing mucosa.
Evaluation for malabsorption and vitamin and mineral deficiencies.
Iron deficiency and macrocytic anemia which result from inflammation of the terminal ileum and poor absorption of folate.
Inflammatory bowel disease affects people of all ages but usually begins before age 30, with peak incidence from 14 to 24. IBD may have a second smaller peak between ages 50 and 70; however, this later peak may include some cases of ischemic colitis.
Hypocalcemia and Vitamin D deficiency, hypoalbuminemia, and steatorrhea resulting from bile salt deficiency
1.5-28% of people with IBD have a first-degree relative who has IBD.
WBC and ESR may be elevated
Colonoscopy- reveals ulcers that are either minor erosions or deep longitudinal fissures. Cobblestone appearance is usually found above the rectum and rectosigmoid areas.
IBD affects Northern European and Anglo-Saxon origin and is 2 to 4 times more common among Ashkenazi Jews than non-Jewish White people from the same geographic location.
The incidence is increasing among Black and Latin American people living in North America
CT is used to identify bowel wall thickening or abscess formation and can be used for guided drainage of abscess.
Both sexes are equally affected
Inflammatory bowel disease (IBD), which includes Crohn disease and ulcerative colitis, is a relapsing and remitting condition characterized by chronic inflammation at various sites in the gastrointestinal tract, which results in diarrhea and abdominal pain.
Oral contraceptives may increase the
risk of Crohn's disease
Cigarette smoking seems to contribute to development or exacerbation
Etiology
Non-steroidal anti-inflammatory drugs (NSAIDs) may exacerbate IBD
Negative for antineutrophil cytoplasmic antibodies (pANCA)
NIH Theory: An autoimmune reaction. Experts think bacteria in your digestive tract can mistakenly trigger your immune system. This immune system response causes inflammation, leading to symptoms of Crohn's disease
Weight loss
Malaise
Moderate to severe abdominal pain
Fever
Weight loss
Strictures
People who have a higher socioeconomic status may have an increased risk of Crohn disease
Barium Enema
Encourage adequate rest and stress reduction to decrease bowel motility and promote healing
Educate on stress management techniques such as guided imagery and mindfulness
Behavioral Therapy
Crohn's and Colitis Foundation
Dietary modifications include low-residue diet when obstructive symptoms are present
Avoid foods high in fiber, inclding whole grain breads and cereals, fresh fruits and vegetables, seeds and nuts.
Pts can eat canned fruits and vegetables and white breads only
When to Refer?
GI
When your patient presents
with one or more of the
following:
Oral elemental or parenteral nutrition may be necessary if unresponsive to treatment or if growth retardation is treatment
Tenesmus
(Fecal Urgency)
Avoid dairy products if intolerant to lactose
If not in acute attack, may eat what they can tolerate
Fever
Nutrition Consult
Non-pharmacotherapy
Female patients before attempting pregnancy or who are pregnant
Bloody diarrhea or
GI bleeding
Chronic abdominal pain
Corticosteroids: Reduce the activity of your immune system and decrease inflammation.
Weight Loss
Joint pain, swelling, or redness
Signs of anemia
(5-ASA) Aminosalicylic Acid Agents: new research is showing this drug class has little value
Cutaneous signs such as: Oral lesions,
erythema nodosum, pyoderma gangrenosum
Ophthalmology Consult
Prednisone 1st line treatment for Mild to Mod:
Initial outpatient treatment: 40mg-60mg/day PO
Ocular Manifestations such as episcleritis, scleritis, iritis, or uveitis
Tapper after 2-4 months
Pts are at higher risk for osteopenia and osteoporosis. Educate on importance of increased weight bearing exercise for bone protection.
Our cultural background, where we grow up, our ethnicity, religion, and diet culture may all play a role in our relationship with food.
Research suggests that up to three quarters of patients with IBD have a decreased satisfaction in eating since their diagnosis
Educate on importance of hydration and low oxalate diet to prevent calcium oxalate stones
Aim to keep the cultural influences in
the diet wherever possible
Antibiotics prevent or treat complications involving infection: abscesses and fistulas. Metronidazole, Cipro, Ampicillin and Tetracycline all show aid in controlling CD ileitis & ileocolonic
Focus on swapping out trigger ingredients for better tolerated alternatives for patient satisfaction
Vaccinations
PNA
Shingrix
TDAP-tetanus every 10 years
Example: Spicy foods: sriracha, chili powder
HPV ages 9-26
HEP A/HEP B
Meningococcus for college students and military
Flu/COVID every fall
No live vaccines while immunosuppressed
Annual PAP smears if immunosuppressed
Try removing heat-producing chilies and add flavor in other ways, such as with fresh cilantro, lime juice, and green onions
Annual skin exam by dermatologist if immunosuppressed
Immunomodulators reduce immune system activity, decreasing inflammation in the GI tract.
Alternatively, the patient may reduce the heat-producing chili in the recipe to a level where they no longer experience symptoms.
Good for patient's who are unresponsive to other first line treatments
Smoking Cessation
Screen for and address anxiety and depression
Good for severe CD pt's who are dependent on high-dose steroids or nonhealing fistulas
Watch for signs of PTSD
Bezzy IBD APP: IBD Community and Support
Abdominal cramping
Flatulence
Soft or semiliquid stools
Steatorrhea
Sudden, violent diarrhea occurring nocturnally
Periods of acute exacerbation alternating with complete remission
Severe cases
Bowel Rest: Few days to a couple weeks
Can drink liquids, with nutrients or hospital admission with IV therapy
Surgery
Indications:
Crohn disease typically affects the ileum and/or colon but spares the rectum
Intermittent areas of diseased bowel are sharply demarcated from adjacent normal bowel (called skip areas)
Epithelioid (sarcoid-like) granulomas are detected in bowel wall or lymph nodes in 25‒50% of cases (pathognomonic).
Small Bowel resection
fistulas
intestinal obstructions
Bleeding that life threatening
Symptoms that can not improrve by medications
Side effects from medications that are life threatening
Subtotal Colectomy
Proctocolectomy
Ileostomy
Prevalence: 100 to 300 per 100,000 people.
Biologic therapies (MOD to Severe Cases): target proteins made by the immune system. Neutralizing these proteins decreases inflammation in the intestines.
Budesonide
Hydrocortisone
Methylprednisolone
LyfeMD is a virtual solution designed by gastroenterologists and registered dieticians to put the power of diet, nutrition, and lifestyle therapies into the hands of patients
Telehealth appointments

No increase in severe infections or malignancy as this is a Human IG Monoclonal Antibody
Can cause bone marrow suppression & increased risk for life threatening infection.
Can cause progressive multifocal leukoencephalopathy in immunocompromised pts. Common SE: fatigue and allergic reaction
When pt's disease is not controlled with low-dose Prednisone
Diet
Low-residue diet when obstructive s/s present.
Rest & stress management to decrease bowel motility and to promote healing
Guided imagery
Refer for concealing
Avoid foods high in fiber: whole grain bread, cereal, fresh fruit & veggies, seeds & nuts
Pt's can have canned fruits and vegetables and should only have white bread.
In-between attacks, pt's can eat whatever they can tolerate
Parental nutrition or oral supplementation for malnutrition pts can sometimes be indicated in severe cases.
This is a life long condition that is not curable, but with proper treatment, support and recourses we can decrease amount of flares pt's experience.
Ask to bring families in during education session, encourage families to be supportive and s/s of decline and when to see help
FIRST LINE THERAPY: Steroids for rapid ease of s/s with prompt referral to Gastroenterology for further symptom management/diagnosis and management.
Proper inflammatory management can reduces the risk of penetrating complications (fistulas/abbesses)
