Overview |
|
|
Definition |
|
Ulcerative colitis (UC) is a chronic nonspecific inflammatory bowel disease
(IBD) involving the mucosa and submucosa of the colon. It involves the rectum
and is characterized by ulceration, bloody diarrhea, and rectal bleeding.
Disease severity depends on degree and extent of inflammation and proximal
colonic involvement. UC may present at all ages, but onset peaks between 15 and
30 years with a secondary onset peak between 60 and 70; it is a serious,
relapsing–remitting disease with significant morbidity
and mortality affecting at least 50 per 100,000 people in the United States.
Higher incidence in Jewish population. Familial incidence is established; 10% to
20% of UC patients have at least one family member affected with IBD. Medical
management controls symptoms in most cases, but colectomy is necessary in about
25% of those affected. |

|
|
Etiology |
|
Unknown. Infectious, genetic, immunologic, and psychological causes
likely. |

|
|
Risk Factors |
|
- Jewish ethnicity (Ashkenazi Jews in particular)
- Positive family history
- A diet high in margarine or chemically modified fat (diet of combined
western foods)
- Psychological disturbances
|

|
|
Signs and Symptoms |
|
UC typically manifests as bloody diarrhea interspersed with asymptomatic
intervals. Onset may be acute and fulminant, but more often is insidious, with
progressively severe urgency to defecate, mild abdominal cramps, and blood and
mucus in stools. Symptoms may include violent diarrhea, high fever, malaise,
abdominal tenderness or pain, anemia, anorexia, weight loss, and arthralgias. In
UC confined to the rectosigmoid area, stool may be normal or hard and dry, with
mucus discharged between or accompanying bowel movements. Stool abnormality
increases with proximal involvement, with up to 20 bowel movements a day,
diffuse cramping, distressing tenesmus, passage of pus, nocturnal sweats, pain,
and diarrhea. |

Diagnosis |
|
|
Physical Examination |
|
Patients with mild or moderate disease usually look well and exhibit few
abnormal signs; bowl sounds and rectal exam (apart from blood) are often normal.
Those with severe disease may also look deceptively well, but usually exhibit
tachycardia, tender colon, and systemic complications. Diagnosis is made on the
basis of history, absence of fecal pathogens, and endoscopic and histological
appearances of the colon.
Mild inflammatory changes include the following.
- Loss of normal vascular pattern
- Fine granularity of mucosa
- Pinpoint hemorrhage to mucosal swabbing
- Exudation of mucopus
Progressive inflammatory changes include the following.
- Coarse granularity and pinpoint ulceration
- Confluent hemorrhage
- Confluent mucopus progressing to gross ulcerations
- Spontaneous hemorrhage
- Exudation of pus
- Pseudopolyps
- Epithelial dysplasia
Acute disease stage includes the following.
- Loss of haustrations
- Thickening of smooth muscle of colon
- "Lead pipe" appearance of colon
- Occasional colonic stricture
|

|
|
Laboratory Tests |
|
- Nonspecific Iron-deficiency anemia
- Leukocytosis Hypoalbuminemia
- Elevated ESR Electrolyte
imbalance
|

|
|
Pathology/Pathophysiology |
|
Endoscopic appearance of mucosa ranges from normal-appearing to complete
denudation; UC is characterized by an even "microcarpet" of tiny ulcers.
Sigmoidoscopic appearance is rarely normal even during asymptomatic intervals.
Pathologic changes include:
- Degeneration of reticulin fibers beneath mucosal epithelium
- Occlusion of subepithelial capillaries
- Infiltration of lamina propria with plasma cells, eosinophils,
lymphocytes, mast cells, and polymorphonuclear leukocytes
- Crypt abscesses, epithelial necrosis, and mucosal
ulceration
|

|
|
Imaging |
|
- Radiography (plain view of abdomen)
- Air contrast barium enema
- Ultrasonography and CT may help determine extent of disease and
complications
|

|
|
Other Diagnostic
Procedures |
|
- Stool samples
- Rectal exam
- Endoscopy with biopsy
- Presence of IL-1ra allele 2 gene is marker for disease severity
- State-Trait Anxiety Inventory (Form Y); Sacks' sentence completion
tests (psychological
influences)
|

|
|
Treatment Options |
|
|
Treatment Strategy |
|
The goal of treatment is to control inflammation, prevent complications, and
replace nutritional and blood losses. Severe cases may require hospitalization;
perforations and hemorrhage may occur without warning. Control of active disease
with drug therapy depends upon extent and severity of mucosal ulceration. Most
widely used are steroids and 5-aminosalicylic acid (5-ASA) drugs.
Corticosteroids can induce remissions but do not prevent relapses. When
indicated, total proctocolectomy with ileoanal pull through and pouch is the
preferred surgical procedure. Indications for surgery include:
- Severe inflammation unresponsive to medical therapy
- Chronic active disease
- Cancer prophylaxis
- Growth retardation in
children
|

|
|
Drug Therapies |
|
Sulfasalazine is the treatment of choice for flare-ups, chronic treatment,
and to reduce frequency of relapse (1 to 4 g/day). Diarrhea may be treated
cautiously with diphenoxylate, loperamide, or opiates. Use of antidiarrheal
agents in severe disease could precipitate toxic megacolon. Toxic megacolon
requires immediate surgery if no improvement within 24 hours after
hospitalization.
- Ulcerative proctitis and proctosigmoiditis may be treated topically
with corticosteroid or mesalamine enema, foam, or suppository; oral prednisone
if refractory (20 to 60 mg/day); osmotic purgation to relieve
constipation.
- Parenteral or oral corticosteroids (prednisone 20 to 60 mg/day) for
more severe flare-ups; patients with chronic activity (10% to 15%) require
continuous low-dose corticosteroids.
- Immunomodulators such as 6-mercaptopurine and azathioprine reduce
need for corticosteroids .
- Oral prednisone (20 to 60 mg/day) or parenteral corticosteroids and
sulfasalazine (1 g bid or tid) and parenteral ACTH are useful in severe active
disease; iron and parenteral hyperalimentation if indicated; antibiotics in
toxic megacolon.
- A new class of topically-acting corticosteroids (budesonide,
fluticasone, beclomethasone dipropionate, prednisolone-21-methasulphobenzoate,
tixocortol pivalate) is an alternative in treating active UC.
- Cyclosporine may induce remission.
- Nicotine patches may induce remission but are not helpful in
maintaining remission.

|
Complementary and Alternative
Therapies |
|
Nutritional and herbal support, mind-body techniques, and physical aids can
help reduce the frequency and severity of ulcerative colitis as well as improve
the integrity of intestinal mucosa and correct nutritional deficiencies. Stress
reduction techniques through biofeedback, hypnosis, or counseling can help
patients to deal productively with stress. Other mind-body therapies such as:
yoga, tai chi, meditation, psychotherapy; stress management such as yoga, deep
breathing, stretching, regular exercise (walking), meditation, prayer,
visualization, and hypnotherapy; and support groups such as the Crohn's-Colitis
Foundation of America (CCFA) may also be helpful. |

|
Nutrition |
|
- Decrease refined foods, sugars, and saturated fats.
- Eliminate all food allergens from the diet. The most common
allergenic foods are dairy, soy, citrus, peanuts, wheat, fish, eggs, corn, and
tomatoes. An elimination/challenge trial may be helpful in uncovering
sensitivities. Remove suspected allergens from the diet for two weeks.
Re-introduce foods at the rate of one food every three days. Watch for reactions
which may include gastrointestinal upset, mood changes, headaches, flushing, and
exacerbation of symptoms.
- A rotation diet, in which the same food is not eaten more than once
every four days, may be helpful in reducing symptoms.
- Specific foods that may exacerbate ulcerative colitis are dairy,
Brassica vegetables (cabbage, brussels sprouts, broccoli, cauliflower, and kale)
and gluten-containing grains (wheat, oats, barley, triticale, rye).
- Fiber supplementation can help reduce abdominal pain, cramping, and
gas. These supplements include psyllium, flaxmeal, slippery elm (Ulmus
fulva) powder, and marshmallow root (Althaea officinalis) powder.
There may be increased bloating and gas initially but this should resolve within
7 to 10 days.
- Pro-flora supplements taken bid to tid can help to rebalance normal
bowel flora and reduce gas and bloating.
- Essential fatty acids may be protective of intestinal mucosa. Max-EPA
or fish oil (3 to 4 g, up to 18 g/day).
- Bromelain (250 to 500 mg between meals) is a proteolytic enzyme that
reduces inflammation.
- Minimum 48 oz. of water/day
- Eliminate caffeine and alcohol.
IBD is associated with low levels of the following nutrients due to poor
absorption, competitive inhibition from medications, or increased
requirement.
- Biotin (300 mcg/day)
- Beta-carotene (50,000 IU/day)
- Vitamin A (50,000 IU/day for one month, then 10,000
IU/day)
- Vitamin C (1,000 mg tid)
- Vitamin D (100 to 200 IU/day) is associated with secondary
hyperparathyroidism and osteomalacia, possibly due to poor calcium absorption
and utilization.
- Vitamin K (10 mg/day) may help normalize prothrombin levels and
decrease bleeding.
- B vitamins, specifically thiamine (100 to 250 mg/day), pantothenic
acid (100 mg/day), riboflavin (50 mg/day), B12 (1,000 mcg/day), and
folic acid (800 mcg/day). Folic acid may be depleted with sulfasalazine use,
which is a competitive inhibitor with folic acid.
- Magnesium (200 mg bid to tid) is associated with weakness,
hypotension, and tetany.
- Calcium (1,000 mg/day)
- Zinc (100 mg bid for one month, then 20 to 30 mg/day)
- Elemental iron (30 mg bid), especially with chronic blood loss.
Glycinate form is least constipating and 30% more absorbable than ferrous
sulfate.
- Selenium (200 mcg/day) protects against oxidative
damage.

Herbs |
|
Ascertain a diagnosis before pursuing treatment. Herbs may be used as dried
extracts (capsules, powders, teas), glycerites (glycerine extracts), or
tinctures (alcohol extracts). Unless otherwise indicated, teas should be made
with 1 tsp. herb per cup of hot water. Steep covered 5 to 10 minutes for leaf or
flowers, and 10 to 20 minutes for roots. Drink 2 to 4 cups/day. Tinctures may be
used singly or in combination as noted. The goal of herbal therapy is to relieve
spasm, reduce inflammation, and encourage healing of the intestinal mucosa.
- Enteric-coated peppermint oil: one to two capsules (0.2 ml peppermint
oil/capsule) tid after meals. Peppermint oil (Mentha piperita) is a
potent spasmolytic that reduces bowel irritability.
- A tincture of equal parts of the following herbs may be taken before
meals (20 to 30 drops tid): Cramp bark (Viburnum opulus),
passionflower (Passiflora incarnata), meadowsweet (Filipendula
ulmaria), wild yam (Dioscorea villosa), valerian (Valeriana
officinalis), and lemon balm (Melissa officinalis). Combined, they
enhance digestion and relieve spasm.
- For acute exacerbation with bleeding, use equal parts of the
following herbs in a tincture (30 drops qid): coneflower (echinacea
purpurea), goldenseal (Hydrastis canadensis), and geranium
(Geranium maculatum)
- Licorice root (Glycyrrhiza glabra) and marshmallow root
(Althaea officinalis) are soothing and promote healing of
gastrointestinal mucosa. Make a tea of licorice root by steeping 1 tsp. in one
cup of hot water for 20 minutes. Drink 3 cups/day. (Contraindicated in
hypertension.) For marshmallow root tea, soak 1 heaping tbsp. of root in one
quart of cold water overnight. Strain and drink throughout the day.
- Quercetin (250 to 500 mg before meals) may help reduce reactions to
food sensitivities.

|
|
Homeopathy |
|
An experienced homeopath should assess individual constitutional types and
severity of disease to select the correct remedy and potency. For acute
prescribing use 3 to 5 pellets of a 12X to 30C remedy every one to four hours
until acute symptoms resolve.
- Arsenicum album for intense cramping and burning, with scanty
dark blood in stool. Patient is restless, chilly, and anxious about their
health.
- China for extreme bloating and gurgling in abdomen; bloody
stools and exhaustion.
- Phosphorus for painless diarrhea with prostration and thirst
for cold drinks.
- Sulphur for morning diarrhea that drives patient out of
bed.
- Mercurius vivus for IBD associated with canker sores and
metallic taste.

Physical Medicine |
|
Castor oil pack. Used externally, castor oil is a powerful anti-inflammatory.
Apply oil directly to skin, cover with a clean soft cloth (e.g., flannel) and
plastic wrap. Place a heat source (hot water bottle or heating pad) over the
pack and let sit for 30 to 60 minutes. For best results, use for three
consecutive days. |

|
|
Acupuncture |
|
Ulcerative colitis may respond to acupuncture, which can help alleviate spasm
and normalize digestive function. |

|
|
Patient Monitoring |
|
Regularly scheduled appointments to evaluate disease activity, and
psychological well-being. The extreme variability and high incidence of relapse
and morbidity predispose patients to anxiety and
depression. |

|
|
Other
Considerations |
|
|
Prevention |
|
Severely ill patients must be monitored closely for peritonitis, perforation,
and toxic megacolon; long-term patients for epithelial dysplasia and cancer.
Annual liver tests and cholangiography for cholestasis are recommended.
Laboratory parameters measured serially during treatment are useful indicators
of disease activity. |

Prognosis |
|
The typically relapsing–remitting course of UC
depends upon severity of initial attack, extent of proximal colonic involvement,
and response to medical treatment. There is no cure excepting colectomy.
Left-sided and ulcerative proctitis have the most favorable prognosis. Drug
treatment is effective for about 70% to 80% of patients; surgery becomes
necessary in the remaining 20% to 30%. About 45% of patients are symptom-free at
any given time; most suffer at least one relapse in any 10-year period. About 5%
succumb to fulminant UC or require immediate colectomy; a smaller percentage
have a single attack without recurrence; and about 15% experience continuous
symptoms refractory to medication and rarely achieve full remission. In the 25%
of patients with ulcerative proctitis (disease localized to the rectum), 10% to
30% experience late proximal spread. UC in children affects the entire colon in
50% of cases. The prognosis is affected by the extent and the severity of the
disease, and by the physical condition of the patient. |

|
|
Pregnancy |
|
Maintenance treatment should be continued, with pregnancy timed to inactive
phase of disease and relapses treated aggressively with corticosteroids.
Corticosteroids and sulfasalazine are safe and nonteratogenic; immunosuppressive
agents are not recommended. Goldenseal, geranium, and quercetin are
contraindicated in pregnancy. In addition, high doses of vitamins should be
avoided. |
