Ulcerative Colitis
John K. Chen, PhD

ABSTRACT
Although some etiologic factors have been suggested as causal of ulcerative colitis, none have yet been proven. Thus, treatment focuses on symptomatic relief. Western medicine offers some pharmacological and surgical options; Oriental medicine offers herbal and acupuncture treatments for ulcerative colitis. This article discusses both approaches to the disease, with an extensive list of herbal and acupuncture therapies.

INTRODUCTION
Ulcerative colitis is a chronic, non-specific, idiopathic, inflammatory, and ulcerative disease of the colon and rectum.1 Both Western and Oriental approaches to this disease are discussed herein.

WESTERN MEDICINE
Etiology
Although many etiologic factors for ulcerative colitis have been suggested, no evidence links any definitively to the condition. Possible risk factors include immunologic factors, infectious agents (such as bacteria, viruses, or amoebae), dietary factors (including chemicals and drugs), and psychosomatic factors. Ulcerative colitis usually occurs between ages 15 and 30, or between 50 and 70.1

Clinical Manifestation
The clinical presentation of ulcerative colitis varies greatly depending on the extent and severity of the illness. It begins with gradual onset of diarrhea with mucus and blood. There are symptomatic and asymptomatic intervals of diarrhea. Patients may also experience tenesmus and left lower quadrant pain and cramps. Systemic symptoms are usually mild or absent in the early stages of ulcerative colitis. If the ulceration involves only the rectosigmoid area, the stool may be normal. Rectal discharge of mucus, red blood cells, and white blood cells will still be present. Systemic symptoms are usually mild or absent.

Occasionally, ulcerative colitis may present as an acute and fulminant attack characterized by sudden violent diarrhea and severe abdominal pain. The abdominal pain and tenderness are most obvious in the left lower quadrant. Patients may have 10-20 bowel movements per day, often accompanied by severe cramps and distressing rectal tenesmus. The stool is filled with mucus, pus, and blood. In addition, malaise, anorexia, weight loss, fever, signs of peritonitis, toxemia, and other systemic symptoms may be present.2

Toxic colitis and toxic megacolon are the most severe forms of ulcerative colitis. In toxic colitis, a transmural extension of the ulcerative process leads to localized ileus and peritonitis. The colon loses its muscle tone and gas begins to accumulate inside the colon, resulting in dilation and paralysis of the colon. When the colon expands beyond 6 cm in diameter, the condition is defined as toxic megacolon (or toxic dilation). In such cases, there is high fever (40ºC [104ºF]), tachycardia, leukocytosis, abdominal pain and distention, and rebound tenderness. A patient with toxic colitis or toxic megacolon should be hospitalized to avoid complications such as perforation, peritonitis, and septicemia.2

Diagnosis
Chronic history of bloody diarrhea with pus and mucus in the stool is suggestive of ulcerative colitis. A definitive diagnosis can be made using sigmoidoscopy, which provides a direct visualization of the rectal mucosa. Colonoscopy is sometimes helpful to differentiate ulcerative colitis from Crohn's disease. Biopsy should be performed if cancer is suspected.2

Differential Diagnosis
Crohn's disease and ulcerative colitis are both inflammatory diseases of the bowel. Crohn's disease may affect any part of the gastrointestinal tract, while ulcerative colitis affects only the colon and rectum.

Bloody stool is usually absent in Crohn's disease but is consistently present in ulcerative colitis. In addition, small bowel involvement, segmental colitis, rectal sparing, and intestinal fistula are diagnostic keys of Crohn's disease.
Other diseases with similar clinical presentation include acute infections of the gastrointestinal tract, ischemic colitis, drug-induced colitis, and colon carcinoma.2,3

Treatment
Since there is no known etiology for ulcerative colitis, no specific therapy is available. Drug treatment focuses on relieving symptoms and is divided into the following classes:

  1. Antidiarrheal. Diarrhea is commonly treated with diphenoxylate, loperamide, or other drugs containing codeine or opium. The most common adverse effects of these drugs are dizziness and sedation. Drugs containing codeine and opium may also cause dependence with long-term use. In addition, antidiarrheal drugs must be given with caution because they may cause toxic megacolon, an emergency condition characterized by dilation of the colon.4,5
  2. Aminosalicylates. These drugs suppress low-grade inflammation and are commonly used for mild to moderate ulcerative colitis. Their usefulness, however, is limited by their frequent adverse effects, including anorexia, dyspepsia, nausea, and vomiting. Commonly used 5-aminosalicylates include sulfasalazine, olsalazine, and mesalamine.4,5
  3. Corticosteroids. Mild to moderate cases of ulcerative colitis can be treated with oral or intravenous corticosteroids. Although corticosteroids have excellent anti-inflammatory effects, long-term use can produce many adverse effects, including but not limited to osteoporosis, glucose intolerance, cataract formation, fluid retention, dependence, and muscle wasting.4,5
  4. Surgery. Emergency colectomy is indicated for life-threatening complications such as massive hemorrhage, free perforation, or fulminating toxic colitis. Elective colectomy is indicated for carcinoma, symptomatic stricture, epithelial dysplasia, and intractable disease. Ulcerative colitis is more localized in comparison with Crohn's diseas; total proctocolectomy usually cures the disease. The disadvantages of surgery include per manent ileostomy, possible sexual dysfunction in males, and the physical and emotional burdens.3

ORIENTAL MEDICINE
Etiology
Similar to Crohn's disease, ulcerative colitis may be caused by constitutional deficiencies, invasion of exterior pathogenic factors, or unbalanced diet. Constitutional deficiencies usually refer to Spleen, Stomach, and Kidney deficiencies. Invasion of exterior pathogenic factors refers to damp-heat or damp-cold. An unbalanced diet high in raw or cold injures the Spleen and the Stomach, and obstructs their functions in transforming and transporting food and nutrients.

Differential Diagnosis
Depending on the severity and characteristics, ulcerative colitis can be divided into 7 major categories: damp-heat in the Large Intestine, damp-cold affecting the Spleen, alternation of heat and cold attacks, Liver overacting on the Spleen, Qi and Blood stagnation, damp accumulation with Spleen deficiency, and Spleen and Kidney Yang deficiency.

Damp-heat in the Large Intestine is commonly caused by excessive consumption of sweet, fatty, and greasy food, and is characterized by an acute and sudden onset of intestinal symptoms. Diarrhea is usually sudden and violent with pus, mucus, and blood. There is a feeling of tenesmus, abdominal fullness and distention, abdominal cramps and pain that diminish after defecation. In addition to intestinal symptoms, the patient may also experience fever, poor appetite, dry mouth, yellow urine, yellow greasy tongue coating, and wiry, slippery, or rapid pulse.

Damp-cold affecting the Spleen is commonly caused by excessive consumption of cold or raw food, fruits, or vegetables. There is a sudden onset of diarrhea with pus, mucus, and blood. The patient also experiences abdominal fullness, distention, and mild to moderate pain that increases with exposure to cold. There is a vague feeling of heaviness in the body and extremities. The tongue coating is white and greasy, and the pulse is soft and slippery.

Alternation of heat and cold attack is a chronic condition that may be caused by many different factors, such as invasion of exterior pathogenic factors or unbalanced diet. The patient experiences constant watery or bloody diarrhea. When there is more heat than cold, bloody diarrhea predominates and the patient experiences abdominal pain, bitter taste in the mouth, dry mouth, urgency to defecate, and fever. When there is more cold than heat, watery diarrhea predominates and the patient experiences abdominal pain (increasing with exposure to cold), aversion to cold, and muscle wasting. The tongue is red with a thin yellow or white coating. The pulse is wiry and thready.

Liver overacting on the Spleen represents an excess condition in which the Wood element overacts on the earth element. The patient has obvious Liver Qi stagnation evident by emotional disturbance. This corresponds with the psychosomatic cause of ulcerative colitis suggested by Western medicine. Clinically, the patient experiences emotional disturbance such as anger, irritability, and short temper. The severity of diarrhea is directly proportional to the severity of emotional disturbance. Other gastrointestinal symptoms include diarrhea with pus, mucus, and blood, abdominal pain, fullness and distention, borborygmus, acid regurgitation, bitter taste in the mouth, and lack of appetite. The tongue is slightly red with a thin white coating, and the pulse is wiry.

Qi and Blood stagnation usually results from damp-heat injuring the Middle Jiao leading to stagnation in the Stomach and Intestines. This condition is characterized by constant pain at a fixed location. Palpation may not be possible as pain increases with touch and pressure. Other symptoms and signs of Qi and Blood stagnation include borborygmus, abdominal distention, chest fullness and distention, acid regurgitation, lack of appetite, and dark facial complexion. The tongue is purple with petechia; the pulse is wiry and knotted.

Damp accumulation with Spleen deficiency represents a chronic condition of ulcerative colitis. Spleen deficiency may be due to congenital deficiency or secondary to excess intake of raw or cold food injuring the Spleen. Damp accumulates as Spleen loses its function to transform and transport food. Clinically, the patient experiences chronic incessant diarrhea with a watery stool, sticky with pus, mucus, and blood. Other local symptoms include dull pain and distention in the abdomen. Malabsorption and malnutrition are common due to the chronic nature of Spleen deficiency. The patient usually experiences fatigue, shortness of breath, lack of appetite, and decreased sense of taste. The tongue is flabby with teeth marks and a thin white coating. The pulse is soft. Spleen and Kidney deficiencies also represent a chronic condition of ulcerative colitis perhaps due to a congenital deficiency or secondary to chronic ulcerative colitis damaging the Spleen and Kidney.

The patient has chronic incessant watery diarrhea with pus, mucus, and blood. Diarrhea may occur early in the morning and throughout the day. Diarrhea worsens with exposure to cold. Other symptoms include fatigue, lack of energy, cold body and extremities, and abdominal pain that diminishes with exposure to warmth. The tongue is pale with a thin white coating; the pulse is deep and thready.

HERBAL TREATMENT
Damp-Heat in the Large Intestine
Herbal formula: Peony combination (shao yao tang). This formula eliminates heat and toxin and is commonly used to treat diarrhea due to damp-heat in the Large Intestine.6,7

Prevention
Both Western and Oriental medicine recognize the importance of diet and its role in the prevention and treatment of ulcerative colitis. Western medicine acknowledges that dietary intake (such as certain chemicals and drugs) may be linked to increased incidence of ulcerative colitis. Oriental medicine recognizes that dietary intake with excessive cold or raw food may injure the Spleen and the Stomach. Therefore, diet plays an important role in both prevention and effective treatment of the illness.

Patients should be encouraged to avoid foods that may trigger recurrence, such as certain chemicals and raw or cold food. Milk, cheese, and other dairy products should be avoided, especially if patients have lactose intolerance. High-roughage foods (such as raw fruits or vegetables) sometimes worsen intestinal obstruction and colic and may need to be avoided. Alcohol should be avoided. In addition to avoiding certain foods, it is equally important to ensure that patients have adequate caloric and fluid intake since malnutrition and dehydration are common problems associated with ulcerative colitis.

Oral iron supplements may be necessary for anemia due to chronic loss of blood through diarrhea; sustained-release iron products are an option. Certain over-the-counter or prescription antidiarrheal drugs may worsen the condition and create toxic megacolon. These drugs should not be taken unless supervised by a qualified health care provider.2-4

DISCUSSION
According to Western medicine, ulcerative colitis is a chronic, non-specific, idiopathic gastrointestinal inflammatory disease. Several etiologic factors have been suggested but none are proven. Because there is no established cause, specific therapy is not available and treatments focus on symptomatic relief. Surgery usually cures the disease, but requires permanent ileostomy and creates physical and emotional burdens.

CONCLUSION
Oriental medicine offers effective treatment for mild to moderate ulcerative colitis. Herbal and acupuncture treatments discussed herein are based on historical treatment guidelines for abdominal pain, diarrhea, and dysentery. Research and clinical experience greatly contribute to the understanding and treatment of this disease. However, Oriental medicine has its limitations. If the patient has such complications as toxic colitis or toxic megacolon, immediate hospitalization is required. In addition, serious complications such as massive hemorrhage, free perforation, or fulminating toxic colitis require immediate surgical intervention.
