What causes IC/PBS?
Some of the symptoms of IC/PBS resemble those of bacterial infection, but medical tests reveal no organisms in the urine of people with IC/PBS. Furthermore, people with IC/PBS do not respond to antibiotic therapy. Researchers are working to understand the causes of IC/PBS and to find effective treatments. In recent years, researchers have isolated a substance found almost exclusively in the urine of people with IC. They have named the substance antiproliferative factor, or APF, because it appears to block the normal growth of the cells that line the inside wall of the bladder. Researchers anticipate that learning more about APF will lead to a greater understanding of the causes of IC and to possible treatments. Many women with IC/PBS have other conditions such as irritable bowel syndrome and fibromyalgia. Scientists believe IC/PBS may be a bladder manifestation of a more general condition that causes inflammation in various organs and parts of the body. Researchers are beginning to exp
