NIH launches unique effort to advance study of urologic chronic pelvic pain...(factors common to all the disorders and ...),Health

The innovative shift in research focus represented by the MAPP initiative is supported by recent epidemiological studies showing that interstitial cystitis/painful bladder syndrome and chronic prostatitis/chronic pelvic pain syndrome are frequently associated with other chronic pain disorders such as fibromyalgia (chronic pain of unknown origin), chronic fatigue syndrome, and irritable bowel syndrome. These latest findings suggest the possibility of common underlying disease processes in these chronic disorders.

"The bladder was assumed to be the origin of the interstitial cystitis/painful bladder syndrome symptoms and the prostate was assumed to be the source of chronic prostatitis/chronic pelvic pain syndrome symptoms," explained Leroy M. Nyberg Jr., M.D., Ph.D., the NIDDK urologist heading the program. "However, in spite of intense study funded by NIDDK, no organ-specific cause has been identified for either disorder."

The MAPP research effort is expected to lead to critical new insights into the underlying causes of urologic chronic pelvic pain. Widening the scope of research will be bolstered by the perspectives of project leaders not normally involved in urologic pelvic pain studies, but who have expertise in relevant scientific disciplines. This will expand the context in which research into interstitial cystitis/painful bladder syndrome and chronic prostatitis/chronic pelvic pain syndrome occurs and will encourage a more comprehensive approach to understanding chronic pelvic pain.

Scientists at Discovery Sites will conduct individual and collaborative multi-site research projects, supported by each Core Site. An important first step in these studies will be the careful and extensive phenotyping (clinical characterization) of the men and women
