Colitis Caused by Antibiotics ------------------------------------------------------------------------------ QUESTION: After a recent chest infection, I developed a terrible bout of diarrhea. This came on with severe stomach cramps and weakness. I took some medicine we had at home, but to no avail. When I finally visited my doctor, he performed a complete examination with a scope, and informed me that I had colitis that was caused by antibiotics. Despite my request, the doctor gave me no medications. I am wondering about both the diagnosis and the treatment. Will you please comment? ------------------------------------------------------------------------------ ANSWER: You may be aware of the fact that many types of bacteria normally live in our digestive system without causing us any ill effects. However, when antibiotics are given to combat infections in any portion of our body, these potent medications kill the normal bacteria in the intestines as well and allow certain resistant bacteria types to take over the territory usually occupied by the "friendly" germs. The most frequently recognized, Clostridium difficile, is a gram-positive rod that produces a poison that can damage the cells that line the colon. When this occurs, all the symptoms which you experienced may be provoked; diarrhea, abdominal pain, and fever. In some cases the disease, known as "antibiotic associated colitis," may be so severe that dehydration, hypotension (low blood pressure) and even perforation of the colon may occur. The diagnosis is based upon the findings of a colonoscopy (examination of the colon with a telescope-like instrument) as well as the results of a stool culture which finds the presence of Clostridium difficile, and the history of recent use of antibiotics. Taking medications which reduce the normal movement of the bowels (peristalsis), and which can help with ordinary diarrhea, is a no-no in this case as it may prolong the time that the bacteria and toxins remain in contact with the tissue of the colon. Treatment varies with the severity of the disease and the findings of the colonoscopic exam, but always requires stopping the antibiotic. Once the antibiotic has been discontinued, the colitis will generally subside by itself in 10 to 12 days, without any additional medication or treatment. Although the presence of the bacterial toxin may remain for several months, no further treatment is necessary if you remain without symptoms. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
