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.

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)
