E. histolytica and G. lamblia are waterborne infectious diseases that cause colitis and liver abscess, and enteritis, respectively.

Important members of this toxin family are Clostridium difficile toxins A and B, which are implicated in antibiotics-associated diarrhea and pseudomembranous colitis. The large clostridial cytotoxins are single-chain toxins with molecular masses of 250-308 kDa. The enzyme domain is located at the N terminus. The toxins are taken up from an acidic endosomal compartment. They glucosylate RhoA at Thr37 also, Rac and Cdc42 are substrates. Other members of this toxin family such as Clostridium sordellii lethal toxin possess a different substrate specificity and modify Rac but not Rho. In addition, Ras subfamily proteins (e.g., Ras, Ral, and Rap) are modified. As for C3, they are widely used as tools to study Rho functions [2] [4]. 

OA were aborted in 2003 due to the development of mild to moderate liver fibrosis in dogs treated for 9 months with high doses of pralnacasan. This was in spite of recent evidence demonstrating the effectiveness of pralnacasan treatment in the acute dextran sulfate sodium (DSS)-induced colitis model, which resembles Crohn s disease (CD) characteristics, and in transient ischemia induced brain damage. 

Colon inflammation 1. AEA levels are elevated in the colon of DNBS-treated mice and in the colon submucosa of TNBS-treated rats, two animal models of inflammatory bowel diseases, and in the biopsies of patients with ulcerative colitis, to control inflammation 1. Inhibitors of degradation (both FAAH and cellular re-uptake)... 

Entamoeba histolytica is an anaerobic rhizopod that occurs in tropical and subtropical areas. It can cause intestinal and extraintestinal manifestations. It is transmitted orally by ingestion of cysts that develop into trophozoites in the large intestine. Amebic trophozoites release several cytolytic factors, e.g. amoe-bapore, which enable the parasite to invade tissue. In intestinal amoebiasis, E. histolyticatrophozoites invade the intestinal mucosa, causing a form of ulcerative colitis with bloody and mucous diarrhoea. Extraintestinal manifestation of amebiasis results in abscess formation, usually in the liver but sometimes in the brain. 

In the pathogenesis of many chronic inflammatory diseases (e.g., rheumatoid arthritis, glomerulonephritis, colitis ulcerosa, Morbus Crohn, atopic dermatitis, psoriasis) autoimmune processes play an important role, too. Although first of all nonsteroidal antiinflammatory agents or glucocorticoids should be applied, immunosuppressive agents may also be indicated. 

As with all drugs, the specific side effects of the quinolones must be considered when they are chosen for treatment of bacterial infections [5]. Reactions of the gastrointestinal tract and the central neivous system are the most often observed adverse effects during therapy with quinolones. It should be underlined, however, that compared with many other antimicrobials, diarrhea is less frequently observed during quinolone treatment. Antibiotic-associated colitis has been observed rarely during quinolone therapy. Similarly, hypersensitivity reactions, as observed during therapy with penicillins and other (3-lactams, is less frequently caused by quinolones. Some other risks of quinolone therapy have been defined and must be considered if a drug from this class is chosen for treatment of bacterial infections.

Promoting an Optimal Response to Therapy The patient receiving a sulfonamide drug almost always lias an active infection. Some patients may be receiving one of Hiese drugs to prevent an infection (prophylaxis) or as part of Hie management of a disease such as ulcerative colitis. 

Discuss hypersensitivity reactions and pseudomembranous colitis as they relate to antibiotic therapy. 

Pseudomembranous colitis may occur after 4 to 9 days of treatment with penicillin or as long as 6 weeks after the drug is discontinued. 

DIARRHEA Diarrhea may be an indication of a super-infection of the gastrointestinal tract or pseudomembranous colitis. The nurse inspects all stools and notifies the primary health care provider if diarrhea occurs because it may be necessary to stop the drug. If diarrhea does occur and there appears to be blood and mucus in the stool, it is important to save a sample of the stool and test for occult blood using a test such as Hemoccult. If the stool tests positive for blood, the nurse saves the sample for possible further laboratory analysis. 

Therapy with cephalosporins may result in a bacterial or fungal superinfection. Diarrhea may be an indication of pseudomembranous colitis, which is one type of bacterial superinfection. See Chapter 7 for a discussion of bacterial and fungal superinfections and pseudomembranous colitis. 

DIARRHEA. Frequent liquid stools may be an indication of a superinfection or pseudomembranous colitis. If pseudomembranous colitis occurs, it is usually seen 4 to 10 days after treatment is started. 

The nurse inspects each bowel movement and immediately reports to the primary health care provider the occurrence of diarrhea or loose stools containing blood and mucus because it may be necessary to discontinue the drug use and institute treatment for diarrhea, a superinfection, or pseudomembranous colitis. 

Abdominal pain, esophagitis, nausea, vomiting, diarrhea, skin rash, and blood dyscrasias may be seen with the use of the lincosamides. These drag s also can cause pseudomembranous colitis, which may range from mild to very severe Discontinuing the drag may relieve mild symptoms of pseudomembranous colitis. 

Bacterial or fungal superinfections and pseudomembranous colitis (see Chap. 7) may occur with the use of both of these drugs. The administration of any drug may result in a hypersensitivity reaction, which can...
