Ulcerative colitis (UC) is a long-term condition that results in inflammation and ulcers of the colon and rectum. The primary symptoms of active disease are abdominal pain and diarrhea mixed with blood. Weight loss, fever, and anemia may also occur. Often, symptoms come on slowly and can range from mild to severe. Symptoms typically occur intermittently with periods of no symptoms between flares. Complications may include megacolon, inflammation of the eye, joints, or liver, and colon cancer.
Hematochezia is the passage of fresh blood through the anus, usually in or with stools. The term is from Greek αἷμα ("blood") and χέζειν. Hematochezia is commonly associated with lower gastrointestinal bleeding, but may also occur from a brisk upper gastrointestinal bleed. The difference between hematochezia and rectorrhagia is that, in the latter, rectal bleeding is not associated with defecation; instead, it is associated with expulsion of fresh bright red blood without stools. The phrase bright red blood per rectum (BRBPR) is associated with hematochezia and rectorrhagia.
Inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon and small intestine. Crohn's disease and ulcerative colitis are the principal types of inflammatory bowel disease. Crohn's disease affects the small intestine and large intestine, as well as the mouth, esophagus, stomach and the anus, whereas ulcerative colitis primarily affects the colon and the rectum.
Colitis is an inflammation of the colon. Colitis may be acute and self-limited or long-term. It broadly fits into the category of digestive diseases.
Mesalazine, also known as mesalamine or 5-aminosalicylic acid (5-ASA), is a medication used to treat inflammatory bowel disease, including ulcerative colitis and Crohn's disease. It is generally used for mildly to moderately severe disease. It is taken by mouth or rectally. The formulations which are taken by mouth appear to be similarly effective.
Sulfasalazine (SSZ), sold under the trade name Azulfidine among others, is a medication used to treat rheumatoid arthritis, ulcerative colitis, and Crohn's disease. It is considered by some to be a first line treatment in rheumatoid arthritis. It is taken by mouth.
4-Aminosalicylic acid, also known as para-aminosalicylic acid (PAS) and sold under the brand name Paser among others, is an antibiotic primarily used to treat tuberculosis. Specifically it is used to treat active drug resistant tuberculosis together with other antituberculosis medications. It has also been used as a second line agent to sulfasalazine in people with inflammatory bowel disease such as ulcerative colitis and Crohn's disease. It is typically taken by mouth.
Microscopic colitis refers to two related medical conditions which cause diarrhea: collagenous colitis and lymphocytic colitis. Both conditions are characterized by the presence of chronic non-bloody watery diarrhea, normal appearances on colonoscopy and characteristic histopathology findings of inflammatory cells.
Collagenous colitis is an inflammatory bowel disease affecting the colon specifically with peak incidence in the 5th decade of life, affecting women more than men. Its clinical presentation involves watery diarrhea in the absence of rectal bleeding. It is often classified under the umbrella entity microscopic colitis, that it shares with a related condition, lymphocytic colitis.
Balsalazide is an anti-inflammatory drug used in the treatment of inflammatory bowel disease. It is sold under the brand names Giazo, Colazal in the US and Colazide in the UK. It is also sold in generic form in the US by several generic manufacturers.
Olsalazine is an anti-inflammatory drug used in the treatment of inflammatory bowel disease such as ulcerative colitis. It is sold under the name Dipentum.
Management of ulcerative colitis involves first treating the acute symptoms of the disease, then maintaining remission. Ulcerative colitis is a form of colitis, a disease of the intestine, specifically the large intestine or colon, that includes characteristic ulcers, or open sores, in the colon. The main symptom of active disease is usually diarrhea mixed with blood, of gradual onset which often leads to anaemia. Ulcerative colitis is, however, a systemic disease that affects many parts of the body outside the intestine.
Ustekinumab, sold under the brand name Stelara, is a human monoclonal antibody used to treat psoriasis. It is also approved to treat Crohn's disease in the United States, Israel and Australia, and ulcerative colitis in the U.S., and in the European Union (EU) among people who have not responded to more traditional treatments. It was found not effective for multiple sclerosis.
Plantago ovata, known by many common names including blond plantain, desert Indianwheat, blond psyllium, and ispaghul, is a medicinal plant native to Western and Southern Asia. The plant can be found growing wild in the southwestern United States where it is native.
Pancolitis, in its most general sense, refers to inflammation of the entire colon. This can be caused by a variety of things. Pancolitis or universal colitis is frequently used in a more specific fashion to denote a very severe form of ulcerative colitis. This form of ulcerative colitis is spread throughout the entire large intestine including the right colon, the left colon, the transverse colon, descending colon, and the rectum. A diagnosis can be made using a number of techniques but the most accurate method is direct visualization via a colonoscopy. Symptoms are similar to those of ulcerative colitis but more severe and affect the entire large intestine. Patients with ulcerative colitis generally exhibit symptoms including rectal bleeding as a result of ulcers, pain in the abdominal region, inflammation in varying degrees, and diarrhea. Pancolitis patients exhibit these symptoms and may also experience fatigue, fever, and night sweats. Due to the loss of function in the large intestine patients may lose large amounts of weight from being unable to procure nutrients from food. In other cases the blood loss from ulcers can result in anemia which can be treated with iron supplements. Additionally, due to the chronic nature of most cases of pancolitis, patients have a higher chance of developing colon cancer.
HLA-B52 (B52) is an HLA-B serotype. The serotype identifies the more common HLA-B*52 gene products.
Vedolizumab is a monoclonal antibody developed by Millennium Pharmaceuticals, Inc for the treatment of ulcerative colitis and Crohn's disease. It binds to integrin α4β7. Blocking the α4β7 integrin results in gut-selective anti-inflammatory activity. It is marketed under the trade name Entyvio.
Etrolizumab is a biopharmaceutical drug candidate being developed for the treatment of ulcerative colitis and Crohn's disease. It is a humanized monoclonal antibody against the β7 subunit of integrins α4β7 and αEβ7. Etrolizumab was developed by Genentech by engineering the FIB504 antibody to include human IgGl-heavy chain and κ-light chain frameworks; it is manufactured in CHO cells.
Lloyd Mayer was an American gastroenterologist and immunologist. He was Professor and Co-Director of the Immunology institute at the Mount Sinai Medical Center, now known as the Lloyd Mayer Immunology Institute.
Eldelumab is a fully human monoclonal antibody that targets chemokine ligand 10 (CXCL10)/Interferon-γ-inducible protein-10 (IP-10) designed for the treatment of Crohn's disease and ulcerative colitis.
