Complex Persistent Pain Conditions: Unique and Shared Pathways of Vulnerability Complex persistent pain conditions (CPPCs) such as headache conditions, fibromyalgia, temporomandibular disorders, irritable bowel syndrome, and vulvar vestibulitis are high prevalent and shared or comorbid chronic pain conditions. There are two features of CPPCs that are fundamental to the aims and goals of this proposal: 1) the etiology of CPPCs is multifactorial and 2) the clinical manifestations of CPPCs are diverse. In this Program Project, we expect to identify a mosaic of risk factors for each of five CPPCs: fibromyalgia (FM), episodic migraine (EM), vulvar vestibulitis (VVS), irritable bowel syndrome (IBS), and temporomandibular joint disorders (TMD). Furthermore, we expect to characterize clusters of patients within each CPPC that vary significantly according to manifestations of their condition in addition to its painful characteristics (e.g., fatigue, dysfunction, sleep loss). Importantly, we expect some clusters of patients to be more alike across CPPCs than within any single CPPC, consistent with our view that there is some overlap in the manifestations of CPPCs. A unifying hypothesis integrating this Program is that multiple genetic factors, when coupled with environmental exposures (e.g. injury, infections, physical and psychological stress), increase the susceptibility to highly prevalent CPPCs by enhancing pain sensitivity and/or increasing psychological distress. To address the aims and goals of the subprojects and cores described in this application, a group of accomplished pain clinicians, pain researchers, psychophysiologists, molecular and cellular geneticists, biostatisticians and epidemiologists have been brought together to form this Program. Studies proposed in this Program Project application seek to identify the psychological and physiological risk factors, clusters, and associated genetic polymorphisms, that influence pain amplification and psychological profiles in enrollees who have established CPPDs. Additionally, the proposed studies seek to characterize the biological pathways through which these genetic variations causally influence CPPCs.
